How Is Metastatic Breast Cancer Treated?


Transcript:

Katherine:

Well, let’s get into the specific treatment options that are available for breast cancer patients. Could you tell us about those?  

Dr. Waks:

So, fortunately, the answer to that question is enormous, because we have so many effective treatment options in breast cancer and generally our patients do very well in the long term when they are diagnosed with early stage breast cancer, so stage I or II or III breast cancer.  

That might involve the breast, it might involve the lymph nodes under the arm, but it hasn’t traveled anywhere else in the body. So I’ll set aside metastatic breast cancer and just talk about stage I, II, and III. 

So, as you may know, we think about as medical oncologists we completely separate treatment considerations for three different subtypes of breast cancer. Those are hormone receptor-positive, HER2-positive and then triple-negative. So, again, highlighting just important developments and not really the overall treatment planning for each of those subtypes, in ER-positive disease or estrogen receptor-positive disease hormonally-driven, estrogen-driven breast cancer – those are all sort of terms for the same thing, I think there have been a couple of important developments over the last few years.  

Probably the most important recent one is the new understanding and demonstration that the CDK4/6 inhibitor abemaciclib, the brand name of that drug is Verzenio. 

That drug when we administer it for two years after a patient has had their surgery and in conjunction with alongside the antiestrogen medicines; the antiestrogen medicines are usually done for a minimum of five years, when we add on to that the CDK4/6 inhibitor abemaciclib, we see that for women with higher risk disease, so maybe some lymph node involvement or a large tumor in the breast or both that the addition of the Verzenio, the abemaciclib seems to decrease their risk of recurrence of breast cancer a couple of years out. So, that’s been an important exciting development. 

Again, not for all women within early stage estrogen-driven breast cancer, but for a little bit more advanced early stage disease like lymph node involvement. You know, we’re obviously always looking for ways to reduce that risk of recurrence for women who have a little bit more risk at diagnosis and the addition of abemaciclib was an exciting and welcome addition to our toolkit there. 

In HER2-positive disease, which is about 20 percent of breast cancers overall, I think what the recent years have brought us is increasing understanding that in many cases we give women too much chemotherapy and that we need to be – so, here it’s less about adding on. Like the Verzenio example I was just talking about and more about individualizing and figuring out in whom and how we can pull back from sort of the kitchen sink approach that we take often to treating a HER2-positive early stage breast cancer and be more thoughtful and more personalized in the amount of treatment that we give women with HER2-positive breast cancer. 

The reason for that is that we’re basically 20 years into understanding that for HER2-positive breast cancers we can treat those cancers very effectively with anti-HER2 antibody drugs like trastuzumab or Herceptin. We didn’t even know that until 20 years ago. And so, Herceptin, trastuzumab and similar drugs have really revolutionized how effectively we can treat women with HER2-positive breast cancers. And so, at this point, it’s becoming more and more clear that we can really lean more on our arsenal of anti-HER2 targeted therapies like Trastuzumab. Pertuzumab (Perjeta) is another one and trastuzumab MTNC and TDM1 is another one. 

So, we have all these excellent smart targeted treatments for women with HER2-positive disease, but yet the standard of care is still to give all those good rational targeted treatments with a whole bunch of chemotherapy that comes with a lot of side effects. 

I think more and more we’re figuring out that we can lean more on our anti-HER2 treatments and require less of the really side effect heavy chemotherapy, but how do we do that thoughtfully? We obviously don’t want to undertreat anybody, so how do we do that thoughtfully? How do we pick out the women who only need the anti-HER2 treatment and can get away with less chemotherapy. I think that’s really what’s exciting in HER2-positive early stage breast cancer right is how do we individualize and take advantage of targeted agents that we have? 

And then finally, in the third subtype of breast cancer which is triple-negative breast cancer which accounts for about 10 percent of breast cancers, the most exciting development there clearly in the last year or so is the realization and the demonstration in randomized clinical trial that we can improve outcomes for those women if we give them not just chemotherapy but also chemotherapy combined with immunotherapy and specifically the immunotherapy agent called pembrolizumab or Keytruda. 

So, up until a year or two ago, the standard for a stage I or II or III triple-negative breast cancer was to get a multiagent chemo regimen and chemo was really the only type of option we had to treat those triple-negative breast cancer patients and now we know from a major important clinical trial called Keynote 522, that if we take a standard chemo backbone and add Pembrolizumab immunotherapy onto it, that we can help those women do better in the long term. So, that’s really a pretty new in the last one or two years standard of care for triple-negative breast cancer. 

And I guess the last thing I’ll say is not about one of those three subtypes of breast cancer but specifically for women with a BRCA1 or BRCA2 mutation associated with their breast cancer, which is a minority. It’s about 5 percent of breast cancer patients. Obviously, the proportion changes depending on your subtype of breast cancer and your age when you’re diagnosed, but for women who have a breast cancer associated with BRCA1 or 2 mutation and have a higher risk or early stage breast cancer. 

So, again, they have a number of lymph nodes involved or a big tumor in the breast or something like that, we now know that we can add on one year of the PARP inhibitor medication called olaparib or Lynparza to the postoperative treatment of those breast cancer patients in addition to whatever other treatment they got; the antiestrogen pills, the chemotherapy, or a combination of those two, and with the addition of olaparib or Lynparza for a year that we can again see better long-term outcomes for those patients and help them avoid recurrences. 

So, that’s not a majority of breast cancer patients but is a targeted treatment that we’re very excited about that definitely makes an important contribution to reducing risk for women with a BRCA1- or BRCA2-associated cancer or men for that matter. I’m saying women, but it could absolutely apply to men.

What Are the Treatment Options for Early Stage Breast Cancer?


Transcript:

Katherine:

What about people who have metastatic disease? What treatment advances are available for them?  

Dr. Waks:

Yeah. You know, I think that’s an incredibly important question and a totally different set of discussions than we have with women with early stage breast cancer and unfortunately and unacceptably at this point for a woman diagnosed with metastatic breast cancer still typically that can become a life-threatening diagnosis. 

So, it’s exceptionally important that we rapidly improve the treatment options that we have for women with metastatic breast cancer. Maybe everybody says this every year, but I think that this year, 2022, has been a particularly exciting year in terms of advances that we’re making in the treatment of metastatic breast cancer, really of all subtypes. I would say the most exciting class of drugs or type of drugs that’s coming out in breast cancer and in all malignancies honestly, is called antibody drug conjugates, which is to say an antibody. So, a molecule that’s targeted to some particular approaching on a cancer cell surface and then is attached to or conjugated to a chemotherapy molecule.  

So, the antibody is like a smart delivery system directly to the cancer cell for what’s call a payload, basically like a sort of action molecule or the killer molecule, which is the chemotherapy. 

Those kinds of antibody drug conjugants have made a huge impact in recent years in improving outcomes for women really with all subtypes of breast cancer, so that drug class I think is a very exciting one to watch in general. In terms of specific recent developments in metastatic breast cancer, so probably the biggest blockbuster development over the past year and really over just the past three months is the understanding that we can break out a subtype of metastatic breast cancer that we really didn’t even talk about before which is called HER2-low breast cancer. So, before if you asked me in May of 2022, there really were only two types of HER2 readouts for a breast cancer tumor. 

There was a HER2-negative breast cancer tumor and there was a HER2-positive breast cancer tumor and as I already told you, the HER2-positive accounts for about 20 percent of breast cancers overall. The other 80 percent are HER2-negative. And so, historically, again you asked me three months ago I would have said if you’re HER2-positive and that 20 percent will give you these different HER2-directed treatments and if you’re not, we can’t use those. And what’s changed is that we’ve developed new antibody drug conjugants. So, drugs that are targeted against in this case the protein HER2 that seem to be so effective and work so well, that you don’t truly have to be HER2-positive.  

You can be HER2-low and still benefit from these treatments, which is to say your cancer has a little bit of HER2 protein on the surface of the breast cancer cells but not a lot. So, not enough to make it positive but enough to make it low in its designation. 

That’s actually a large proportion of breast cancer patients. It’s over 50 percent of breast cancer patients, so it’s significantly more than HER2-positive, so a large proportion of breast cancer patients actually fit into this new category called HER2-low and we now know from data that were presented in June of 2022 and then published in the New England Journal of Medicine, which is our biggest most high profile academic medical journal, we know that for patients who fall into that HER2-low category, again that’s more than 50 percent of breast cancer patients, that they can, if they have a metastatic breast cancer, benefit from this new antibody drug conjugate called trastuzumab deruxtecan (Enhertu).  

When it was compared to the existing chemo options we have for those patients which do have some efficacy but nonetheless, when trastuzumab deruxtecan was compared to the existing chemo options, it clearly looked better for patients with HER2-low breast cancer. So, that was not just an exciting advance in terms of new treatment options which we always love to be able to offer to patients but also in terms of breaking out this entirely new designation and subcategory that captures more than half of our metastatic breast cancer patients and helping us to offer them something new and hopefully will be a pathway for other drugs to be developed in this space and for this new subcategory. 

So, that was very exciting. I’ve been talking about it with patients all the time in the past just three months since those data came out.  

You know, a second antibody drug conjugate that has also been very exciting in recent months and recent years is called sacituzumab govitecan which Trodelvy is the brand name of that one. That’s an antibody drug conjugate that’s targeted against a different protein on the cell surface that’s targeted against the protein Trop-2, so that’s where the Trodelvy comes from. It’s targeting Trop-2. That’s an antibody drug conjugate that we’ve known for probably three or more years now can be very effective in triple-negative metastatic breast cancer. So, we’ve had that option for a number of years in metastatic triple-negative breast cancer. 

But again, just in the past few months have gotten good and exciting data that this Trodelvy or sacituzumab drug also works in estrogen-driven breast cancers.  

And so, it’s giving another option to patients with not just triple-negative but also estrogen-driven breast cancer. So, that was another very recent development just in the last three months or so. 

Katherine:

That’s really exciting.

Katherine Banwell:

Since prostate cancer affects men differently, let’s review what factors could impact which treatment is right for their individual disease. How about we start with symptoms? 

Dr. Rana McKay:

So, yeah. I mean absolutely. I think symptoms are definitely something that plays into effect. Sometimes when patients are first diagnosed, they may not have symptoms. But, you know, boney pain, symptoms of urinary obstruction. You know, there’s specific treatments and strategies that we can deploy to help with those kinds of things. You know other factors that I think I – we take into account when we’re making decisions about which agent should any one patient receive is where are their sites of metastases? Is there disease just in the bones and lymph nodes or are there other organs involved? What’s the genomic make-up of the tumor? There are certain treatments that we would utilize if someone had a certain specific you know, genetic make-up for their tumor. You know, other things that are really important are what kind of drugs has the patient seen before or has that tumor been exposed to? Because that also helps us strategize for what to give them in the future.  

Katherine Banwell:

Do you take into consideration the patient’s comorbidities and their age and overall health? Things like that?  

Dr. Rana McKay:

Absolutely. Yeah. I think we need to absolute take that in account. I think – I think age is one thing. But I think functional status is just as – as important as the actual number itself because people are very different regarding the things that they can do at various age limits and so, that absolutely takes into account weighing the side effects of any given therapy and how that may interact with someone’s existing comorbidities and it may be something that we have to work with a team of other doctors to basically make sure that there is comprehensive, well-rounded care for any one patient.   

For example, some therapies may increase the risk of hyper-tension or increase the risk of volume overload. And so, if somebody has issues with that already we may have them see a cardiologist so we can make sure that, you know, we’re kind of addressing the totality of the patient experience. 

Katherine Banwell:

What do you mean by volume overload? 

Dr. Rana McKay:

Volume overload, I mean if they’ve got too much fluid on board. So, maybe if they have heart failure or something like that, and we have a therapy that’s going to cause them to retain fluid. And so then, we would have to work with a cardiologist to make sure that they don’t run into issues 

Katherine Banwell:

Mm-hmm. Once a man is undergoing treatment for advanced prostate cancer, how are they monitored to see if it’s actually working? 

Dr. Rana McKay:

So, a lot of ways. So, one is by just, you know, visiting with the patient. Making sure that their symptoms are in check. Making sure that they’re not developing new aches or pains that are worrisome. It’s by checking their labs in addition to their organ and bone marrow function. We would check their PSA. And PSA isn’t the whole story. But it is one factor that contributes to us determining whether treatment may or may not be working. It’s also doing intermittent scannings. So, you know, CT scans of the organs, of the lymph nodes. Bone scan and now we actually have PSMA based imaging, which can be integrated to help assess where the disease is and not yet being utilized to assess whether something is working, because we haven’t really defined the criteria there. But, it can be utilized as well.  

Understanding Advanced Prostate Cancer Treatment Approaches

Understanding Advanced Prostate Cancer Treatment Approaches from Patient Empowerment Network on Vimeo.

What approaches are available to treat advanced prostate cancer? Dr. Rana McKay discusses advanced prostate cancer treatment goals and reviews current options for patients.

Dr. Rana McKay is a medical oncologist at UC San Diego Health and an associate professor in the Department of Medicine at the UC San Diego School of Medicine. Learn more about Dr. McKay, here.
 
 

Katherine Banwell:

We’re going to talk about treatment approaches. But first, how would you define treatment goals? 

Dr. Rana McKay:

So, you know when I look at defining treatment goals it’s focusing on what do we want to achieve from the standpoint of the cancer? Meaning, you know, what are objectives that are associated with patients living longer?  

And then what are objectives and strategies that we can set-up to make sure that patients are living better? So, I think the treatments are basically set up to basically help you achieve those two goals. What can we do to help you live longer and feel better? 

Katherine Banwell:

Yeah. Well, let’s walk through the types of treatments that are used today to treat advanced prostate cancer. What are the treatment causes and who are they appropriate for? Let’s start with surgery, for instance. 

Dr. Rana McKay:

So, surgery is something that’s utilized early on when people are diagnosed with cancer. It tends to be utilized when the cancer has not necessarily spread to other parts of the body but is still localized within the prostate itself, or maybe there’s just some little bit of breakthrough in the capsule. Sometimes it can be used in people who have involvement of the prostate cancer in the lymph nodes. But it’s generally not utilized in people who have cancer that’s spread to other parts of the body. 

Katherine Banwell:

Mm-hmm. What about other treatment classes? What are they? 

 Dr. Rana McKay:

So, radiation can also be utilized. Radiation is a treatment modality that can be used for people with localized disease, and also it can be utilized for people with advanced disease to treat the primary tumor. 

Additionally radiation therapy can be used to help treat symptoms if there’s a bone lesion causing pain or other areas that are causing discomfort. Sometimes radiation to those areas can mitigate pain. When I think about the treatment classes for prostate cancer, they generally break down into several categories. The first, most predominant category is the hormonal therapy category. Hormonal therapies are really the backbone of treatment for men with prostate cancer, and they include the more traditional hormonal therapies that really work to just drop testosterone. So, just LRH – L – LRHA agonists and antagonists and also, they include newer hormonal therapies in the form of pills that really target strategies at also affecting testosterone function and testosterone production. Another class is also the chemotherapy agents. There are two FDA-approved chemotherapies for prostate cancer that are life-prolonging, and there’s a certain role for chemotherapy for people with advanced disease. 

There’s also immunotherapy that can be utilized. There’s a vaccine therapy that’s actually one of the first FDA vaccines for any solid tumor that’s proving in prostate cancer that can be utilized. There’s also radio pharmaceuticals.  

So, these are specific agents that deliver bits of radiation to specific areas. Whether it be radium 223, which targets the bone or the newest radio pharmaceutical, which was approved called Lutetium PSMA that basically delivers beta-radiation to little – sites of PSMA expressing cancer cells and the last category that I would highlight is the category of targeted therapy. There are two targeted therapies for prostate cancer for patients who have like genomic alterations. Those include the drugs olaparib and rucaparib. So, as you can see there’s a wide spectrum of drugs that can be utilized to really keep this disease at bay.

Katherine Banwell:    

Hello and welcome. I’m Katherine Banwell, your host for today’s program. Today we’re going to focus on how patients can aim to live and thrive with advanced prostate cancer. We’re going to discuss treatment goals and the role patients can play in making key decisions. Before we get into the discussion, please remember that this program is not a substitute for seeking medical advice. Please refer to your healthcare team about what might be best for you. Well let’s meet our guests today. Joining me is Dr. Rana McKay. Dr. McKay, welcome. Would you please introduce yourself?

Dr. Rana McKay:     

Of course. Thank you so much for having me. My name is Rana McKay and I’m a GU medical oncologist at the University of California San Diego.  

Katherine Banwell:    

Excellent. Thanks so much for taking time out of your schedule to join us. Since this webinar is part of PEN’s Thrive series, I’d like to ask you from your perspective, what do you think it means to thrive with advanced prostate cancer?

Dr. Rana McKay:        

That’s a very good question and I think that’s what um, a lot of patients want to actually you know, do in their day-to-day existence. I think it means that they are combatting their disease. They’re taking a proactive role in um, you know, uh tackling um, their illness. They um, are uh, attentive to sort of doing the activities of daily living that really bring them joy and satisfaction and happiness and setting up a treatment plan that is a mutually agreed upon treatment plan with their clinician. That they have buy-in on. That their caregivers have buy-in on. That allows them to do the things that they love to do while keeping their cancer at bay.

Katherine Banwell:    

Okay. Thank you for sharing your insights. Before we move onto treatment, I mentioned that this webinar is focused on advanced prostate cancer. What does it mean for prostate cancer to be considered advanced?

Dr. Rana McKay:        

So, generally what that means is that the cancer may have spread outside of the body – outside of prostate to other parts of the body such as the bone or the lymph nodes which is a common location where prostate cancer um, uh, can go. Additionally, it may mean that the cancer may have come back after um, it was initially treated with an intent um, to cure um, a patient. But then you know the PSA demonstrates um, that you know, there’s a rise in the PSA and the cancer is recurrent.

Katherine Banwell:    

As you mentioned uh, appropriate treatment is part of thriving. We’re going to talk about treatment approaches. But first, how would you define treatment goals?

Dr. Rana McKay:       

So, you know when I look at defining treatment goals it’s focusing on what do we wanna achieve from the standpoint of the cancer? Meaning, you know, what are objectives that are associated with patients living longer?

And then what are objectives um and strategies that we can set-up to make sure that patients are living better? So, I think the treatments are basically set-up to basically help you achieve those two goals. What can we do to help you live longer and feel better?

Katherine Banwell:    

Yeah. Well, let’s walk through the types of treatments that are used today to treat advanced prostate cancer. What are the treatment causes and who are they appropriate for? Let’s start with surgery, for instance.

Dr. Rana McKay:       

So, surgery is something that’s utilized uh, early on when people are diagnosed with cancer. It tends to be utilized when the cancer has not necessarily spread to other parts of the body but is still localized within the prostate itself or maybe there’s just some little bit of breakthrough in the capsule. Sometimes it can be used in people who have involvement of the prostate cancer in the lymph nodes. But it’s generally not utilized in people who have cancer that’s spread to other parts of the body.

Katherine Banwell:    

Mm-hmm. What about other treatment classes? What are they?

Dr. Rana McKay: 

So, radiation can also be utilized. Radiation is a treatment modality that can be used for people with localized disease and um, also it can be utilized for people with advanced disease to treat the primary tumor.

Additionally radiation therapy can be used to help treat symptoms um, if there’s a bone lesion causing pain or other areas that are causing discomfort. Sometimes radiation to those areas um, can um, mitigate pain. When I think about the treatment classes for prostate cancer um, they generally break down into several categories. The first um, um, most predominant category is the hormonal therapy category. Hormonal therapies are really the backbone of treatment for men with prostate cancer and they include the more traditional hormonal therapies that really work to just drop testosterone. So, just LRH – L – LRHA agonists and antagonists and also, they include um, newer hormonal therapies in the form of pills that really target um, strategies at also affecting testosterone function and testosterone production. Another class is also the chemotherapy agents. There are two FDA approved chemotherapies for prostate cancer that are life prolonging and um, uh there’s a certain role for uh, chemotherapy for people with advanced disease.

There’s also immunotherapy that can be utilized. Um, there’s a um, uh, vaccine therapy that’s actually one of the first uh, FDA vaccines for any solid tumor that’s proving in prostate cancer that can be utilized. There’s also radio pharmaceuticals.

So, these are specific agents that deliver um, a bits of radiation to specific areas. Whether it be radium 223 which targets the bone or the newest radio pharmaceutical, which was approved called uh, lutecium PSMA that um, basically delivers beta-radiation to little – sites of PSMA expressing cancer cells and the last category that I would highlight is the category of targeted therapy. There are uh, two targeted therapies for prostate cancer for patients who have like genomic alterations. Those include the drugs olaparib and rucaparib. So, as you can see there’s a wide spectrum of drugs that can be utilized to really keep this disease at bay.  

Katherine Banwell:    

Dr. McKay, for these treatment classes, what can patients expect as far as side effects?

Dr. Rana McKay:       

Absolutely. So, I think side effects – discussing side effects is a really important part of the discussion for selecting any one given therapy and in general, I think um, when we talk about the hormonal therapies one of the side effects that people can get is largely fatigue.

But a lot of the symptoms are related to low testosterone. And so, that may mean muscle loss, bone loss, um, you know, uh, hot flashes, um, fatigue, decrease libido, um… So, you those are things to consider with hormonal therapies. With the chemotherapies, I think the big ones we worry about are fatigue, risk of infection, um blood counts dropping a little bit, people getting tired, numbness and tingling in the hands and feet can occur, some swelling in the legs are common side effects for chemotherapy agents. With regards to the um, uh, immunotherapy with the vaccine therapy, it actually tends to be a fairly well tolerated treatment. Maybe some fatigue, rarely some dizziness or some lip – lip sensitivity, numbness with the – the process of kind of collecting the cells. But it actually tends to be fairly well tolerated.

The um, targeted therapies can cause fatigue. They can cause the blood counts to drop and can impact bone marrow function. There can be sometimes GI side effects. Nausea, um, rash, um and then the immune therapy, the pembrolizumab, that is FDA approved sometimes that can cause immune related adverse events which is kind of over activation of the immune system developing you know, what I’d call it as the itises. Colitis or pneumonitis which is inflammation of various organs and symptoms related to wherever that may be.

Katherine Banwell:    

When should a patient consider a clinical trial as a treatment option?

Dr. Rana McKay:        

So, I generally think that a patient should consider a clinical trial at almost every juncture that a – a clinical decision is being made. I think sometimes there’s this misperception that, “Oh. Clinical trials should only be utilized when I don’t have any other options.” Where in fact I would say clinical trials should be an option to discuss every single time a treatment is being changed. Um, because you know the ultimately the goal is to make sure patients are as I said, living longer and living better and um, you know, making sure that clinical trials are an option on the table at every juncture is really a key step in that process.

Katherine Banwell:    

What are the benefits of being part of a clinical trial?

Dr. Rana McKay:       

So, I think there’s a lot of benefits. I think um, you know, uh for patients with advanced disease it may provide access to drugs that they otherwise not necessarily have access to.

Um, so the standard of care therapies you know, we can prescribe those at any juncture. They’re standard of care. But clinical trials um, really offer an opportunity to experiment with a uh, uh another agent um, and doesn’t necessarily take away from the standard of care options.

I think um, the other thing is you know, I think a lot of patients with advanced prostate cancer, they um, they – want to give back to the community. They want to leave a legacy. They want to contribute to the science. They wanna be a part of that mission to make tomorrow better than today for men with prostate cancer and I think participating in clinical trials can really help achieve that goal. Um, and also benefit the individual as well.

Katherine Banwell:    

What about emerging treatments? Are there any that patients should know about?

Dr. Rana McKay:       

Absolutely. So, there’s a lot of treatments that I think are currently undergoing extensive testing.

There’s um, additional uh, targeted therapies um, for example CDK46 inhibitors that are being tested broadly in the um, um hormone resistant space and the newly diagnosed setting. Um, there’s um, also AKT inhibitors. There are other targeted therapies that are being tested. There’s novel hormonal treatments that target resistant pathways like the antigen receptor degraders. There’s a slew of immunotherapy options um, cell therapy, bi-specific antibodies that are also being tested. So, there’s a lot of really exciting and novel treatments that are looking at overcoming resistance for people with advanced disease.

Katherine Banwell:    

Hm. Do you recommend that men with advanced prostate cancer get the COVID vaccines and the boosters?

Dr. Rana McKay:       

Very good question and in general, I do recommend the vaccines. Especially for patients with advanced disease and those that are on therapy. Um, several studies have demonstrated that patients with cancer are at increased risk of having complications related to COVID and particularly patients that are on active treatment with cancer are at even greater riskSo, um, I would definitely recommend vaccination as a preventative strategy to prevent really complications related to COVID.

Katherine Banwell:    

Mm-hmm. Thanks, Dr. McKay. That’s helpful information. Since prostate cancer affects men differently. Let’s review what factors could impact which treatment is right for their individual disease. How about we start with symptoms?

Dr. Rana McKay: 

So, yeah. I mean absolutely. I think symptoms are definitely something that plays into effect.

Um, sometimes when patients are first diagnosed, they may not have symptoms. But, you know, boney pain. Um, Symptoms of urinary obstruction. You know, there’s specific um, uh, treatments and uh, strategies that we can deploy to help with those kinds of things. Um, you know other factors that I think I – we take into account when we’re making decisions about which agent should any one patient receive is where are there sites of metastases? Um, is there disease just in the bones and lymph nodes or are there other organs involved? Um, what’s the genomic make-up of the tumor? Um, there are certain treatments that we would utilize if someone had a certain specific you know, uh genetic make-up for their tumor. You know, other things that are really important are what kind of drugs has the patient seen before or has that tumor been exposed to? Because that also helps us strategize for what to give them in the future.

Katherine Banwell:    

Do you take into consideration the patient’s comorbidities and their age and overall health? Things like that? 

Dr. Rana McKay: 

Absolutely. Yeah. I think we need to absolute take that in account. I think – I think age is one thing. But I think functional status is um, just as – as important as the actual number itself because people are very different regarding um,  the things that they can do at various uh, age limits and so, that absolutely takes into account weighing the side effects of any given therapy and how that may interact with someone’s existing comorbidities and it may be something that we have to work with a team of other doctors to basically make sure that there is comprehensive, well-rounded care for any one patient.

For example, some therapies may increase the risk of hyper-tension or increase the risk of volume overload and so, if somebody has issues with that already we may have them see a cardiologist so we can make sure that um, you know, we’re kind of addressing the totality of the patient experience. 

Katherine Banwell:    

What do you mean by volume overload?

Dr. Rana McKay: 

Uh, volume overload I mean if they’ve got too much fluid on board. So, maybe if they have heart failure or something like that and we have a therapy that’s gonna cause them to retain fluid. And so then, we would have to work with a cardiologist to make sure that they don’t run into issues.

Katherine Banwell:    

Right. That makes sense. What are the common symptoms of advanced prostate cancer?

Dr. Rana McKay: 

So, um, you know, I would probably say there common symptoms and just because somebody has these symptoms doesn’t mean they have prostate cancer. But fatigue, weight loss, urinary symptoms, trouble urinating, you know, benign prostatic atrophy is one of the most common symptoms or most common conditions in men and um –

Katherine Banwell:    

What does that mean?

Dr. Rana McKay: 

Um, so sort of benign enlargement of the prostate. Um, you know that’s a common phenomenon that happens with age and it can affect somebody’s ability to urinate.

Um, but um you know uh, sometimes with prostate cancer it can also impact somebody’s ability to urinate. Their stream, their flow. Um, they may have rectal discomfort. They may feel tired, boney pains. Usually, I tell patients you know persistent progressive symptoms that are just you know not going away, not getting better. Those need to be looked at by a physician to evaluate further. 

Katherine Banwell:    

Mm-hmm. You mentioned genetic mutations. Should patients advocate for genetic testing if they haven’t had it already?

Dr. Rana McKay: 

Um, it all depends on uh, what kind of uh, where they are in the process. So, for most men who have advanced disease, they should undergo genetic testing of both their tumor, and it is also recommended to do hereditary testing for patients who have advanced disease. Um, and that information may not necessarily be utilized at the exact time that the test is done.

But it may be utilized down the road for treatment options at a later time point. Um…

Katherine Banwell:    

Mm-hmm. Once a man is undergoing treatment for advanced prostate cancer how are they monitored to see if it’s actually working?

Dr. Rana McKay: 

So, a lot of ways. So, one is by just you know, visiting with the patient. Making sure that their symptoms are in check. Making sure that they’re not developing new um, aches or pains that are worrisome. It’s by checking their labs um, in addition to their organ and bone marrow function. We would check their PSA. Um, and PSA isn’t the whole story. But it is one factor that contributes to us determining whether treatment may or may not be working. It’s also doing intermittent scannings. So, um, you know, uh, CT scans of the organs, of the lymph nodes. Bone scan and now we actually have PSMA based imaging which can be integrated to help um, assess uh, where the disease is and um, not yet being utilized to assess whether something is working because we haven’t really defined the criteria there.

But um, it can be utilized as well.

Katherine Banwell:    

Mm-hmm. Dr. McKay, how would you define precision or personalized medicine and how close are we getting to personalized medicine for advanced prostate cancer?

Dr. Rana McKay: 

Yeah. So, what I – how I define it is the right treatment for the right patient at the right time. It’s basically you know, based off of somebody’s genomic profile of their tumor and ideally that genomic profiling is done close to the time that that treatment is being initiated. So, within six months or twelve months of somebody starting a given therapy we understand the genetic make-up of the tumor. The tumor has you know, for example a BRCA1 alteration and we know that olaparib is a drug that can be utilized and has demonstrated efficacy for people that have that mutation and then we would use that agent. So, it’s basically trying to um, personalize therapy based on the genomic information of that tumor.

And um, I think we are getting there. There are actually trials now that are being launched that are bio-marker driven trials with bio-marker selected therapies for patients based on -off of not just DNA but also RNA to help with um, allocating a given therapy.   

Katherine Banwell:    

What do you feel are the common obstacles to care for a man with advanced prostate cancer?

Dr. Rana McKay: 

So, I think that there can be a lot of obstacles with regards to um, you know, comprehensiveness of the care. You know it’s one thing to sort of, “Okay. This is the next therapy to treat you with.” But there’s a lot of side effects that can happen with any one given therapy and ensuring that there is open dialogue between um, uh a man and his – his clinician and caregivers.

You know, I think that that can sometimes be a hurdle. Like that open communication can be so important. It’s not just about picking the next best drug but it’s ensuring that there’s sort of comprehensiveness in care. I think a lot of um, you know, patients they may not necessarily know and they’re really kind of dependent on their clinician to sort of go through the compendia of options that may be available and why one may be better than the other for any one given scenario. So, I think it’s like that shared decision-making, that open dialogue.

Um, you know, I think also thinking about advocacy networks, I think um, you know, I can say things until I’m blue in the face like this is what being on ADT feels like. But I think sometimes actually connecting with another patient whose gone through the same experience who can kind of weigh in from the patient perspective like what it actually feels like, I think is not to say a hurdle. But I think we can do a better job as a medical community of making those networking connections available for patients so they can be a part of a broader community of individuals like them going through the same thing they’re going through.

Katherine Banwell:    

Yeah. It helps to know that there are others going through exactly what you’re going through or similar symptoms. We received a patient question prior to the program. What is the difference between my PSA level and Gleason score?     

Dr. Rana McKay: 

Yeah. So, very good question. So, Gleason score is something that is determined based off a pathologic assessment. So, it’s basically you know, a biopsy is done from the prostate or the – the surgical specimen from the removal of the prostate is looked at under the microscope and a Gleason score is based off what something looks like underneath a microscope and ideally, a Gleason score is given really only for the prostate – for tissue derived from the prostate.

So, if somebody has a bone biopsy for example or a lymph node biopsy, they’re not going to necessarily get a glycine score per se. It’s been – been validated from the prostate itself and ideally, also, an untreated prostate. So, if somebody has you know had radiation therapy and then has a biopsy, the Gleason score there is – there should not necessarily be a notation of what a Gleason score is. It’s really an untreated prostate. Now PSA is prostate specific antigen and it’s a protein that’s made from the prostate gland and it’s found in circulation. PSA doesn’t hurt any – the actual you know, molecule itself is – is innocuous. It doesn’t hurt anything. It’s just a marker of um, sometimes can be a marker of burden of disease in prostate cancer and I think sometimes we as clinicians do you know, you know a disservice to some patients because I think we fixate – we can fixate a lot on PSA.

But PSA is not the whole story and it’s one factor of several factors that we take into account in determining whether someone needs treatment or whether a treatment is working or not working.

Katherine Banwell:    

Why should patients feel confident using their voice in partnering in their care? Do you have any advice?

Dr. Rana McKay: 

Um, I mean it’s – it’s absolutely important for patients to share their perspective and for there to be shared decision making at every single juncture along the way. Even around decisions to not treat. So, you know, I think it’s a lot of um – there’s a lot of grays in prostate cancer and a lot of art in deciding what treatment to do and at what specific time and for any given patient given the values that that patient brings to the table, they may come back with a different decision compared to another patient. So, without the patient you know voicing what their values are it’s impossible to make a treatment decision.

So, it is so critically important to have that open communication with your clinician.

Katherine Banwell:    

So, in addition to that – in conjunction with that, should men diagnosed with advanced prostate cancer consider a second opinion or consulting with a specialist?

Dr. Rana McKay: 

I think it’s always a great idea to get a second opinion. Um, you know, I think that um, you know, it will only empower individuals um, when they seek sort of a second opinion to either confirm um what their physician has already told them and then they have reassurance that they’re on the right path or maybe provide some new um, novel insights that they can take into consideration and just think about how that could be applied to them. So, you know, I think that a second opinion is always really valuable.

I will balance that by saying um, sometimes it can be detrimental if there’s lots of opinions because I will say that coming to a consensus when there’s lots of different specialists that are involved, and everybody makes the soup a little bit differently –

Katherine Banwell:    

Yeah.

Dr. Rana McKay: 

Sometimes that I think that can actually um, hurt patients in being able to actually come to a decision because then they’re like, “I don’t know what decision to make. This person said do this. This person said do that. This person said do that.” Um, and so that can sometimes be um, detrimental. But a second opinion, I do always encourage it. I do always value it. But I always want the patient to bring it back to me so I can share with them and discuss, “Okay. I understand. This is why x said X-Y-Z. This still aligns. This still doesn’t.” They need a quarterback like you know, it’s one thing to sort of get second opinions. But I think every man with prostate cancer should have a quarterback that’s driving their care and advocating for them.

Katherine Banwell:    

Yeah. How can patients find specialists near them?

Dr. Rana McKay: 

So, um, I will say that they are national comprehensive cancer institutes. They’re all across the country in rural areas and not. I think um, you know finding the closest NCI designated comprehensive cancer center close to you is probably a good place to start and identifying who is seeing um patients with genetic urinary malignancies or prostate cancer at that facility is a good place. I think the prostate cancer foundation is an excellent advocacy group for patients with prostate cancer. They have a tremendous amount of resources um, to help connect patients with um, clinicians, and other resources um, in their journey with cancer.

Katherine Banwell:    

How can caregivers best support their loved ones?

Dr. Rana McKay: 

So, I think being present is one of the first things. Um, you know, I think that uh, um, you know, uh, being you know, supportive, being present.

Like you know, attending the doctor – doctor’s visits. It doesn’t necessarily have to be every single doctor visit. But those critical doctor visits where um, you know clinical decisions are being made. I think it’s really important also um, to there may be some hesitancy on the part of patients to sometimes be open or vocal with their clinicians about various aspects of what they may be experiencing at home, or they may be undermining or sort of – I think caregivers can help in sort of giving an outsider’s perspective. “Well, this is how things are going at home,” and “You know this is how things are,” and “These are the things that we value and we’re gonna go on this family trip,” and “This is a big-ticket item for us. So, how can we work around planning a treatment plan that allows us to do that?” So, I think it’s really important.

Katherine Banwell:    

ASCO was held in June. Is there news from the conference that patients should know about?

Dr. Rana McKay:        

Yeah. So, I think some of the biggest therapies in prostate cancer that was one of the newest therapies that was just FDA approved is um, Lutetium PSMA. It’s um, a radioligand therapy that targets specifically PSMA expressing cells. Um It delivers a little bit of beta radiation to those cells. Um, that therapy was approved this past Spring and there highlights at ASCO about the utility of this therapy. Um, and again, there’s a series of novel compounds that are being tested in prostate cancer not yet ready for prime time but a lot of exciting work that’s being done um, to try to get new drugs that work better for our patients.

Katherine Banwell:    

Mm-hmm. Going back to ASCO and new developments, how can patients stay informed about research developments like – like these that happen at ASCO.

Dr. Rana McKay:

So, very – very good. I think there’s a lot of networks for people with prostate cancer. I think one like I mentioned, the prostate cancer foundation it’s a wonderful community. Um, that really focuses on making sure that up to date, you know, uh, evidence-based data is uh, distributed to patients in a manner that is – that makes sense. That’s there’s not a lot of medical jargon and so I think that the PCF is really a wonderful resource. Uh, ASCO itself also has um, you know patient interfacing you know, materials through their website.

American Cancer Society does as well. Um, the American Cancer Society can also be a wonderful resource for patients that are newly diagnosed or going through treatment.

Katherine Banwell:    

Mm. Before we end the program, Dr. McKay, I wanted to ask. Are you hopeful that men can thrive with advanced prostate cancer?

Dr. Rana McKay:       

Oh, I am absolutely hopeful that they can thrive. I mean that is um, the name of the game and I think there’s a lot of um, uh, people who can look to for motivation.

Um, uh, to basically show that despite treatment, despite having advanced disease patients can thrive and continue doing all of the things that they love that give them joy and satisfaction in their lives.

Katherine Banwell:    

It seems like there’s a lot of progress and hope in the field which is good. Dr. McKay thank you so much for taking the time to join us today.

When Should Prostate Cancer Patients Consider a Clinical Trial?


Transcript:

Katherine:                  

I’d like to address a list of common concerns about treatment that we’ve heard from the community. So, I’d love to get your take on these. “There’s nothing that can be done about advanced prostate cancer.” Is that true?

Dr. Choudhury:           

So, that is very much untrue in that even patients with pretty advanced prostate cancer – even what we call “high-volume” kinds of prostate cancer – can live for years, and years, and years with appropriate treatments.

And the concern, oftentimes, is that the way that we get those years, and years, and years are with treatments that lower levels of testosterone, and I’m guessing that some of your questions coming up are related to concerns around side effects of treatment. But many of our patients tolerate those side effects pretty well and can live quite a good, and vigorous, and fulfilling life even with pretty advanced prostate cancer.

Katherine:                  

The next one: “Clinical trials are a last-resort treatment option.”

Dr. Choudhury:   

Yeah, so, as I’d mentioned before, clinical trials can be appropriate anywhere along the treatment trajectory of prostate cancer, and they are often being compared against standards which are often pretty good, but can we make them better? And certainly, participating in clinical trials isn’t for everyone, but for a long of our patients who are interested in seeing if an experimental approach might be beneficial to them or contributing some knowledge to patients down the line really do find trial participation to be quite fulfilling.

Katherine:                  

All right. The next one is: “Prostate cancer isn’t genetic, so I don’t need to be tested.” Is that the case?

Dr. Choudhury:        

No. So, it turns out that prostate cancer is actually one of our most heritable cancers. Somewhere between 40% and 50% of the predisposition to prostate cancer is actually genetic, or inherited based on family. So, the part that’s tricky and the part that is hard to maybe explain to patients is that a lot of that heritability is not encompassed in particular cancer genes in the way that many people are familiar with with breast and ovarian cancers, which are often linked to genes called “BRCA-1” and “BRCA-2.” So, a small subset of patients with prostate cancer do have alterations in that BRCA-2 gene, or BRCA-1, or ATM, or some other genes involved in breast and ovarian cancers.

And that does impact, potentially, their treatments down the line, and certainly is impactful for themselves, their siblings, their children as far as, potentially, screening recommendations for other cancers. But oftentimes, we’ll do one of these tests in patients who have a pretty extensive family history of prostate cancer, and they come out negative, and the patient is very confused because they clearly have a family history, but it’s because not all the risk of prostate cancer is actually encompassed in these gene tests that we run.

Katherine:                  

Ah, okay. The next concern is “I’ll lose all sexual function when I receive treatment.”

Dr. Choudhury:         

So, it very much depends exactly what the treatment is, and what’s being offered, and what the recovery is like.

So, for example, for patients who go into a prostatectomy and have very good erectile function, it’s not inevitable that you’ll lose your sexual functioning after a prostatectomy. There is a process – we kind of refer to it as “penile rehab” – of using medications like a Viagra or Sialis to restore the blood flow. You could use certain things like vacuum pump devices to restore the blood flow, and again, it’s not inevitable that people are going to lose their sexual functioning after a prostatectomy.

Even with testosterone suppression, while it plays a role in libido and erectile function, it’s not inevitable that people lose their libido and erectile function completely, even on these drugs. But certainly, more often than not, people will lose their erectile function on testosterone-lowering medications.

And so, there are alternative ways to get erections – involving, again, use of vacuum pump devices or injections that people can give themselves into the penis. People can have penile implant surgery to be able to get erections that way. And so, it’s really dependent on what the situation is.

Again, none of those more mechanical interventions are really ideal, but particularly when people have a defined course of treatment – for example, a surgery or radiation with a brief course of hormones – people can recover erectile function even after those sorts of interventions. And if they can’t, then we do have other approaches that will allow people to still be able to be sexually intimate with their partner after all of the treatments are completed.

Katherine:                  

Dr. Choudhury, one more concern: “My symptoms and side effects can’t be managed.”

Dr. Choudhury:           

Yeah. So, again, it’s very rare that we run into situations where there are side effects or symptoms that can’t be managed at all, in the sense that we have very effective medications against hot flashes, or moodiness, or pain, or –just fatigue. And certainly, lifestyle plays a big role in this. Also, a lot of the symptoms that people express are related to underlying depression and anxiety issues, and certainly, engaging with a mental health provider can be helpful in terms of managing those as well.

And then, there’s a lot of nonpharmacologic treatments – meaning nonmedication approaches that can provide people a lot of benefit in terms of their quality of life, and we have an integrative center called the Zakim Center for Integrative Medicine that helps with the relaxation techniques, and massage, and yoga, and acupuncture…

And people find different approaches to help manage these symptoms and side effects. And so, it’s very unusual where we run into a situation where the side effects are unbearable and unmanageable. Usually, we can manage them in some form of way that allow people to have, again, a good quality of life and a meaningful life, even on prostate cancer treatment.

Using Your Voice to Partner in Your Prostate Cancer Treatment Decisions


Transcript:

Katherine:                  

Hello, and welcome. I’m Katherine Banwell, your host for today’s webinar. Today, we’re going to explore the goals of advanced prostate cancer treatment and discuss tools for playing an active role in your care decisions.

Before we get into the discussion, please remember that this program is not a substitute for seeking medical advice. Please refer to your healthcare team about what might be best for you. Joining us today is Dr. Atish Choudhury. Dr. Choudhury, welcome. Would you please introduce yourself?

Dr. Choudhury:        

Hello. Thank you so much for the invitation. So, I’m a medical oncologist at Dana-Farber Cancer Institute, and I’m the codirector of the prostate cancer center at the Dana-Farber/Brigham and Women’s Cancer Center. And I serve as the chair of the Lank Center for Translational Research as well, and ’t’s my pleasure to be here.

Katherine:                  

Thank you so much for taking the time out of your schedule to join us. Today, we’re talking about advanced prostate cancer.

What exactly does “advanced” mean in terms of this cancer?

Dr. Choudhury:          

Yeah. So, it’s actually a pretty broad term, and it can mean different things in different contexts. But generally, what it means is that it’s cancer that has extended outside of the confines of the boundaries of the prostate itself – either locally where it is into the surrounding fat around the prostate capsule or to local lymph nodes, where it could also spread to other parts of the body – like lymph nodes, bone, and other organs.

So, it can really mean different things depending on the context.

Katherine:                  

Before we get into the types of treatment available, let’s start by understanding the goals of treatment. What are the goals of advanced stage prostate cancer?

Dr. Choudhury:              

So, in general, the goal of treating any cancer is to a live a long, happy, healthy life with limited quality of life troubles from the cancer itself or its treatments. And so, for localized prostate cancer, that generally means treating with curative intent – that we give radiation or surgery, potentially in combination with hormonal treatments so that the cancer is taken care of and people can be cured and not need further treatments moving forward at all.

And there are situations, even in fairly advanced cases, where that’s a reasonable and accomplishable goal. And there are other situations that we might not be able to cure the cancer completely, but the treatments can be quite effective at keeping it under control and keep people with a very good quality of life so that prostate cancer is not a day-to-day burden for them and that they can survive with cancer for years, and years, and years.

Katherine:                  

It sounds like these goals would be determined with members of your healthcare team. So, who is typically on a patient’s prostate cancer healthcare team?

Dr. Choudhury:            

Yeah. So, generally, the consultations here at Dana-Farber are multidisciplinary, with a medical oncologist, a radiation oncologist, and a urologic oncologist – so, a surgeon.

And so, if a patient is a good candidate for treatment to the prostate itself, then certainly, the surgeon and the radiation oncologist will talk about those treatments. And if the treatment is primarily with medications, then the medical oncologist will generally sort of take the lead. But there is often a role for local treatment to the prostate itself, even in cancer that’s spread beyond the prostate. So, that’s why the multidisciplinary consultation is so important.

Katherine:                  

Right. What do you feel is the patient’s role as a team member?

Dr. Choudhury:           

Absolutely. So, I think it is very important for the patient to make sure that they come into these multidisciplinary meetings with questions around “What is my stage?” “What are the choices?” “What do I expect with treatment? Without treatment? With the various treatment options?” And basically, to take in the advice that they’re getting from the different members of the multidisciplinary team, and really think about how that’s impactful for them and their goals for themselves and what they really hope for the short term and for the long term.

I think what gets tricky is that there’s really very not-great sources of information that’s out there online and in YouTube videos and things like that, and I think it does play an important role for the patient to really understand what are the real high-quality sources of information – they tend to come from academic medical centers like ours. And certainly, we do encourage second opinions at other high-quality, high-volume centers so that the patients understand that the recommendations that are being made are generally made based on the based data and with people with a lot of experience at treating their kind of cancer.

Katherine:                  

What about caregivers? How do they fit into the team?

Dr. Choudhury:             

Caregivers are critical because patients are not always the most expressive at, really, what their wants, and needs, and desires are. And especially when they’re on treatment, sometimes they’re not so expressive around the things that are bothering them on a day-to-day basis.

So, the caregivers are really important for communication with us to be kind of another set of eyes and ears in terms of kind of reporting what the patient’s symptoms are or what their goals or desires are that maybe they themselves don’t feel comfortable expressing. But they also play an important role in helping us with, kind of, lifestyle recommendations to the patient. Because certainly, much of the process of doing well with prostate cancer treatments is kind of lifestyle modifications – makes sure you’re eating healthy, exercising regularly – and the caregivers can play a very important role in making sure that patients stick to that kind of regimen as well.    

Katherine:                  

I would think one of the issues for a patient too is that just having a cancer can be overwhelming and can make it difficult for them to even remember all the questions and concerns that they have.

Dr. Choudhury:            

Yeah, that’s absolutely critical, and the caregivers play a very important role. So, often, people who are not partnered, for example, will just bring a friend to these appointments just to be that second set of eyes and ears.

Katherine:                  

Dr. Choudhury, we received this question from an audience member prior to the program: What is palliative care?

Dr. Choudhury:           

So, palliative care is really a branch of medicine that helps with symptom management. And so, that symptom management doesn’t necessarily have to be end-of-life sort of symptoms relating to death and dying. It can be just along the way to help with managing the symptoms related to cancer and its treatment, but also to be kind of another medical provider to help with communication of goals of care – what’s really bothersome, what’s really important – so that we kind of incorporate those wishes and desires into the management decisions that we make.

So, a patient does not have to be at end-of-life to engage with palliative care. Certainly, even earlier engagement with palliative care can be helpful to maximize quality of life along the treatment journey. But as symptoms become more bothersome, certainly, our palliative care colleagues can be incredibly helpful – not just in helping manage pain, but also nausea, also depression and psychological side effects. So, they’re a really critical part of our treatment team.

Katherine:                  

Yeah. I think we have a pretty good understanding and the goals of treatment. So, let’s walk through the types of therapy that are used today to treat prostate cancer.

If you would start with surgery?

Dr. Choudhury:            

Sure. So, surgery is a radical prostatectomy, and they take out the prostate – they take out neighboring structures called seminal vesicles, they take out the surrounding fat, and they’ll usually take out some neighboring lymph nodes as well. And there are advantages of surgery in that when the prostate is out, the pathologist can examine the whole prostate front to back, side to side, as well as those neighboring structures to really understand the stage of the cancer – “Where is it?” – and also, the grade – “Is it a high-grade cancer, a low-grade cancer, somewhere in the middle?”

And it really helps guide “What is the risk of developing recurrence afterwards, and are there further treatments that we should be giving after the surgery? For example, radiation to the prostate bed to decrease the risk of recurrences. Surgery does have its own set of potential side effects and complications, so it’s not appropriate for everyone, but in general, that’s the process.

Katherine:                  

What other treatment options? You mentioned radiation. What else is there?         

Dr. Choudhury:          

Yeah, so, radiation comes in two forms: there’s seed radiation, which is implantable little radioactive pellets that are implanted throughout the prostate. And then, there’s external radiation, and that can be given in several forms and over several schedules that it’s really important to discuss with the care team.

The other forms of treatment that people on this call might’ve heard about or read about are in a category called “focal treatments,” and these are basically ways to – and the term we use is a blade but zap – an area of the prostate using lasers, or high-intensity ultrasound, or with freezing an area of the prostate, or with something called “irreversible electroporation.”

These are basically all ways to, again, zap an area of the prostate either with heat or with cold with the intention of killing off cancer cells in an area. And the trouble is that none of these treatments have actually been demonstrated to improve outcomes related to prostate cancer compared to just surveillance alone. And it does complicate, sort of, the monitoring afterwards to see if something has come back.

But there might be very selected patients where there’s an area of cancer that’s seen on a scan – like an MRI – with no cancer seen outside of that area who might decide to pursue this possibility of focal treatment with the goal of maybe putting off the need for something like radiation or surgery. But that’s something that really should be discussed with a multidisciplinary team so that people really understand what they’re getting into in terms of risks and potential benefits.

So, those treatments are not really considered standard at this time.

Katherine:                  

What about hormonal therapy?        

Dr. Choudhury:   

Yeah, so, hormonal therapy plays a role in the treatment of prostate cancer, really depending on the stage and the other treatments that are being considered. So, for example, if a patient is going to surgery for a localized prostate cancer, in general, we wouldn’t use hormonal treatment either before or after the surgery unless they’re planned for radiation after the surgery.

However, for patients who have intermediate risk or higher localized prostate cancer and are getting radiation, then we will often recommend hormonal treatments, which are basically testosterone-lowering drugs, to make the radiation work as well as possible. And then, for patients who have advanced cancer beyond where surgery or radiation is going to be of help, then, hormonal treatments are important to treat the cancer wherever it is.

And that’s because prostate cancer cells, wherever they are in the body – wherever they’re in the prostate itself, or in lymph nodes, or bones, or other organs – depend on the testosterone in your body to supply a fuel – to support its growth and survival.

And so, lowering the level of testosterone in the body basically deprives the cancer cells of that fuel and starts a process of killing cancer cells even without any need for radiation, or chemotherapy, or things like that. However, hormonal treatments are not curative. They don’t kill all the cancer – they kill some and put the rest to sleep. And so, if you stop the hormonal treatment, the cancer will grow back, and that’s why it’s not a treatment on its own for localized prostate cancer.

And that’s also why, for prostate cancer that’s spread, we often add on additional medications to the testosterone-lowering drugs to be more effective at really killing the cancer wherever it is compared to the testosterone suppression alone.

Katherine:                  

Oh, I see. For advanced disease, what treatments are available for patients that are hormone-sensitive or -resistant?

Dr. Choudhury:           

Yeah, so “hormone-sensitive” means that the cancer has advanced, but the patient hasn’t started on testosterone-lowering drugs yet. And so, as I had mentioned, testosterone lowering is really the backbone of treatment of these patients. And so, there are additional treatments that have been demonstrated previously to be effective after testosterone-lowering by itself stops working, and these include a chemotherapy drug called docetaxel. And in addition, there are more potent hormonal drugs called abiraterone, enzalutamide, apalutamide, and darolutamide.

And the role of these other drugs is to block hormonal signaling within the cancer cells from hormones other than testosterone. And so, by doing the more potent hormonal drug in conjunction with the testosterone lowering, that leads to a much deeper response – much more tumor shrinkage – and, it turns out, also prolonged survival in patients treated with those combination treatments – compared top people who are treated with testosterone lowering alone and then receive these drugs later.

So, there’s something about treating more aggressively at the beginning in this hormone-sensitive state that plays out in prolongation of survival. And not only prolonged survival, but improved quality of life due to delaying the symptoms of cancer grown and progression.

Katherine:                  

Right.        

Dr. Choudhury:   

When we then talk about castration resistant disease, certainly we use the same classes of drugs, but then, there’s a wider armamentarium of things that we use that include, again, other kinds of chemotherapy.

There are radiation drugs, and an approved drug Radium-223. And there’s another drug on the horizon called Lutetium PSMA. There are immune therapy drugs – something called Sipuleucel-T – and then, this is also a situation where we do genetic testing of the cancer to understand if there’re certain –what we call “therapeutic vulnerabilities.”

Other treatment options that are available based on the genetics of the cancer that might be helpful in some people? And specific options include a chemo-immune therapy called “Keytruda” in a small subset of patients with particular genetic changes involving genes involved in mismatched repair of DNA. And then, there’s another set of targeted treatments called “PARP inhibitors” for certain sets of patients who have alterations in genes involved in homologous recombination repair of DNA.

So, that’s all very complicated, and so that’s why it’s important to get treated with high-volume providers of prostate cancer patients so that they’re really aware and onboard with these various treatment options that are available.

Katherine:                  

Yeah. Where do clinical trials fit in?

Dr. Choudhury:       

So, clinical trials can fit in anywhere along the treatment trajectory for prostate cancer. It’s not something that’s reserved for kind of late-stage disease. So, for example, for people with localized disease, there are different types of treatment strategies that might be available to maybe enhance the activity of the surgery or the radiation that’s planned. And so, we might consider a clinical trial even for localized prostate cancer.

And then, anywhere along the way, there are standard treatments that are available, and then, there are some experimental approaches that might be available. And the experimental approaches might be to add an additional drug to the standard or to actually – what we call “deescalate treatment” – give a little bit less of the medication and see if the outcomes are the same. And these are tests.

And so, the control arm, when there’s a randomized trial, is generally considered a standard of care. And then, the experimental arm is some alteration or deviation from that standard. But many of our trials are also single-arm trials where we’re testing some experimental regimen that all patients who participate in the trial will take part in, and it’s really important for the patient to ask, “What are the clinical trials available?” “What are the alternatives as far as standard treatments?” and “Are there other clinical trials other than the one that’s being discussed,” that might be appropriate for them?

Katherine:                  

Are there emerging approaches that patients should know about?   

Dr. Choudhury:        

Yeah. So, a lot of the emerging approaches are related to the genetics of the prostate cancer, as I just mentioned. And then, these different forms of radiation drugs – in addition to the ones that have already demonstrated survival advantage, there are other ones in the pipeline. And then, one thing that patients are very curious about is immune therapy approaches to prostate cancer.

Now, the standard kind of immune therapy drugs that are approved for lung cancer, and melanoma, and kidney cancers don’t tend to work particular well for prostate cancer. But there are many clinical trials trying to combine those kinds of drugs with other drugs or have newer approaches to immune therapies that patients with advanced cancer can certainly ask about.

Again, all of this is really experimental, and people need to understand that these sorts of approaches aren’t going to help everyone. But participating in a clinical trial allows our patients to contribute to knowledge that can be useful for other patients down the line.

Katherine:                  

Right. Now that we’ve delved into the types of treatment, let’s talk about what goes into deciding on an approach. What do you typically consider when determining the best treatment approach or option for a patient?

Dr. Choudhury:   

So, the starting point and the ending point is the patient themselves. And so, “the patient” means “What is their age? What is their fitness level? What are their activities? What’s the overall life expectancy? What are there other medical issues?” And then, we consider the cancer – “What is the stage? What is the grade? Where has it spread to, if it’s spread?”

And then, we try to incorporate all of those pieces with data – with clinical trials that have already been reported – and we have a lot of data in prostate cancer from patients who’ve participated in clinical trials, often randomized to one approach versus another, that gives us a sense of “What are the approaches that really benefit patients in terms of increasing likelihood of cure or prolonging the survival?”

And so, once we incorporate all of those things, we can come up with some treatment suggestions, and then patient preference on those suggestions obviously plays a very important role. But sometimes, we start down a line, and the patient is having troublesome side effects or it’s not working as well as we’d really hoped, and it’s important to be adaptive and to change things if things are not going down a route that we’d really hoped. So, that’s an ongoing conversation. It’s not that you make a treatment plan at the first visit and that’s the plan that’s stuck with throughout the whole course of things.

It’s a conversation at every visit on how things are going in terms of how the patients are doing and how the cancer is responding. And then, again, try to manage side effects as well as we can and adjust things if we need to along the way – and maybe switch to something that’s potentially going to be better tolerated or more effective, depending on what we see.

Katherine:                  

Right. It sounds like there are many factors to weigh when making this decision. I’d like to address a list of common concerns about treatment that we’ve heard from the community. So, I’d love to get your take on these. “There’s nothing that can be done about advanced prostate cancer.” Is that true?

Dr. Choudhury:           

So, that is very much untrue in that even patients with pretty advanced prostate cancer – even what we call “high-volume” kinds of prostate cancer – can live for years, and years, and years with appropriate treatments.

And the concern, oftentimes, is that the way that we get those years, and years, and years are with treatments that lower levels of testosterone, and I’m guessing that some of your questions coming up are related to concerns around side effects of treatment. But many of our patients tolerate those side effects pretty well and can live quite a good, and vigorous, and fulfilling life even with pretty advanced prostate cancer.

Katherine:                  

The next one: “Clinical trials are a last-resort treatment option.”

Dr. Choudhury:   

Yeah, so, as I’d mentioned before, clinical trials can be appropriate anywhere along the treatment trajectory of prostate cancer, and they are often being compared against standards which are often pretty good, but can we make them better? And certainly, participating in clinical trials isn’t for everyone, but for a long of our patients who are interested in seeing if an experimental approach might be beneficial to them or contributing some knowledge to patients down the line really do find trial participation to be quite fulfilling.

Katherine:                  

All right. The next one is: “Prostate cancer isn’t genetic, so I don’t need to be tested.” Is that the case?

Dr. Choudhury:        

No. So, it turns out that prostate cancer is actually one of our most heritable cancers. Somewhere between 40% and 50% of the predisposition to prostate cancer is actually genetic, or inherited based on family. So, the part that’s tricky and the part that is hard to maybe explain to patients is that a lot of that heritability is not encompassed in particular cancer genes in the way that many people are familiar with with breast and ovarian cancers, which are often linked to genes called “BRCA-1” and “BRCA-2.” So, a small subset of patients with prostate cancer do have alterations in that BRCA-2 gene, or BRCA-1, or ATM, or some other genes involved in breast and ovarian cancers.

And that does impact, potentially, their treatments down the line, and certainly is impactful for themselves, their siblings, their children as far as, potentially, screening recommendations for other cancers. But oftentimes, we’ll do one of these tests in patients who have a pretty extensive family history of prostate cancer, and they come out negative, and the patient is very confused because they clearly have a family history, but it’s because not all the risk of prostate cancer is actually encompassed in these gene tests that we run.

Katherine:                  

Ah, okay. The next concern is “I’ll lose all sexual function when I receive treatment.”

Dr. Choudhury:         

So, it very much depends exactly what the treatment is, and what’s being offered, and what the recovery is like.

So, for example, for patients who go into a prostatectomy and have very good erectile function, it’s not inevitable that you’ll lose your sexual functioning after a prostatectomy. There is a process – we kind of refer to it as “penile rehab” – of using medications like a Viagra or Sialis to restore the blood flow. You could use certain things like vacuum pump devices to restore the blood flow, and again, it’s not inevitable that people are going to lose their sexual functioning after a prostatectomy.

Even with testosterone suppression, while it plays a role in libido and erectile function, it’s not inevitable that people lose their libido and erectile function completely, even on these drugs. But certainly, more often than not, people will lose their erectile function on testosterone-lowering medications.

And so, there are alternative ways to get erections – involving, again, use of vacuum pump devices or injections that people can give themselves into the penis. People can have penile implant surgery to be able to get erections that way. And so, it’s really dependent on what the situation is.

Again, none of those more mechanical interventions are really ideal, but particularly when people have a defined course of treatment – for example, a surgery or radiation with a brief course of hormones – people can recover erectile function even after those sorts of interventions. And if they can’t, then we do have other approaches that will allow people to still be able to be sexually intimate with their partner after all of the treatments are completed.

Katherine:                  

Dr. Choudhury, one more concern: “My symptoms and side effects can’t be managed.”

Dr. Choudhury:           

Yeah. So, again, it’s very rare that we run into situations where there are side effects or symptoms that can’t be managed at all, in the sense that we have very effective medications against hot flashes, or moodiness, or pain, or –just fatigue. And certainly, lifestyle plays a big role in this. Also, a lot of the symptoms that people express are related to underlying depression and anxiety issues, and certainly, engaging with a mental health provider can be helpful in terms of managing those as well.

And then, there’s a lot of nonpharmacologic treatments – meaning nonmedication approaches that can provide people a lot of benefit in terms of their quality of life, and we have an integrative center called the Zakim Center for Integrative Medicine that helps with the relaxation techniques, and massage, and yoga, and acupuncture…

And people find different approaches to help manage these symptoms and side effects. And so, it’s very unusual where we run into a situation where the side effects are unbearable and unmanageable. Usually, we can manage them in some form of way that allow people to have, again, a good quality of life and a meaningful life, even on prostate cancer treatment.

Katherine:                  

Thank you, that’s really helpful. I’d like to talk about the term “shared decision making.” What does that mean to you, exactly?       

Dr. Choudhury:   

So, shared decision-making really means that when the physician conveys information to a patient, that the patient really understands what’s being said, and what, really, the alternatives are – and the real risks and the benefits of the different alternatives. And so, if a patient goes to see a surgeon and they say, “Well, we should take this out,” and there’s never really discussion of what the risks and benefits of the alternatives are –and the alternatives could be just watching, or radiation, or even more intensive treatment, then that’s not really shared decision making.

But what I think is not exactly shared decision making is when the patient is getting information from really non-knowledgeable or non-reputable sources and then starts to come up with conclusions based on hearsay or people trying to sell them a product that really hasn’t been FDA approved or really tested. And so, those are situations where when the information is really not good, then we can run into troubles with communications. But there are a lot of really excellent sources for patient information that’s available, and the Prostate Cancer Foundation is a really good source, and a lot of the academic prostate cancer centers are really great sources of information.

And so, being educated and asking good questions is really the best way for a patient to feel comfortable that they’re not missing anything and that they’re, again, having all the information that they need to make a good choice for themselves.

Katherine:                   

Do you have any advice to help patients speak up if they’re feeling like they’re not being heard?

Dr. Choudhury:           

Sure. So, I mean, there’s never any barrier to bringing up concerns with whoever that you’re seeing, and if you feel like whoever you’re talking to isn’t being receptive to those concerns, then certainly, second opinions are very useful. But if you see multiple doctors and they’re kind of telling you the same thing based on good evidence, then you probably have to take in what they’re saying, and process it, and see if it really does apply to your particular situation.

But any cancer doctor who really has your self-interest in mind will be very open to discussing the concerns that you have, so you should absolutely bring them up.

Katherine:                  

To close, Dr. Choudhury: What would you like to leave the audience with? Are you hopeful?

Dr. Choudhury:          

Yes. I’m actually incredibly hopeful. There’s been such a transformation in our diagnosis and management of prostate cancer compared to when I first started as an independent attending back in 2012. In the last ten years, there’s been so many new treatments that’ve been approved in the last decade and a lot of newer technologies available for staging patients – really finding where their prostate cancer is.

And newer technologies for treating the cancer wherever it is and in a really smart way. And so, we can really individualize our treatments for the patient that’s in front of us being a bit more intensive for people with higher-volume or higher-risk cancers, and actually potentially being able to back off treatment, and actually stopping some of the testosterone-lowering drugs in patients who are responding exceptionally well to the medications and the local treatments that we’re giving them.

And then, also, I’m really hopeful about the newer treatments and newer technologies that are on the horizon. We have newer – what we call “molecularly targeted agents.” We have new approaches involving immune therapies that are being tested – newer radiation approaches. And I feel like all of this put together allows us to, again, satisfy the goal of maintaining patients’ good, healthy, meaningful quality of life moving forward.

Katherine:                  

Yeah. Dr. Choudhury, thank you so much for taking the time to join us today.

Dr. Choudhury:           

Oh, you’re welcome. It’s so wonderful to have this opportunity.

Why should you ask your doctor about metastatic breast cancer genetic testing?

The National Comprehensive Cancer Network – also known as the NCCN – recommends that every metastatic breast cancer patient undergo genetic testing. The test results can help predict how your cancer may behave and could indicate that one type of treatment is more effective than another.

This testing identifies specific gene mutations, proteins, chromosomal abnormalities, and/or other molecular changes that are unique to YOU and YOUR breast cancer.

There are two main types of genetic tests used in breast cancer:

  • Germline or hereditary genetic testing, which identifies inherited gene mutations in the body. These mutations are present from birth, can be shared among family members and be passed on to subsequent generations.
  • The second is somatic or tumor genetic testing, which identifies markers that are unique to the cancer itself. It is also commonly referred to as genomic testing, biomarker testing, or molecular profiling. Somatic mutations are NOT inherited or passed down from family member to family member.
  • Depending on your history, your doctor may order one–or both–of these types of tests.

So why do the test results matter?

  • If you have specific gene mutations – such as the BRCA1 or BRCA2 inherited gene mutations – it could indicate that a targeted treatment approach may be the most effective option. For example, there are two oral targeted therapies that are approved specifically for use in metastatic patients with BRCA1-positive or BRCA2-positive breast cancer.
  • Results of these tests may also help you to find a clinical trial that may be appropriate for your particular cancer.
  • Additionally, results from germline genetic testing may suggest that close family members should also be tested to determine their risk.

How can you insist on the best breast cancer care?

  • First, always speak up and ask questions. Remember, you have a voice in YOUR breast cancer care.
  • Ask your doctor if you have had–or will receive–genetic testing, including germline and somatic testing.
  • If you have already undergone genetic testing, bring a copy of your results to your current doctor, so they can understand your results and determine whether additional testing is needed.
  • Have a discussion with your healthcare team about the test results – including which markers were detected and how results may impact your care and treatment plan.
  • Ask whether your family members should meet with a genetic counselor or undergo testing to help gauge their risk of developing breast cancer.
  • And, finally, bring a friend or a loved one to your appointments to help you process and recall information.

What Is a Prostate Cancer Genetic Mutation?

Why should you ask your doctor about genetic testing?

The test results may predict how your prostate cancer will behave and could indicate that one type of treatment may be more effective than another type.

Genetic testing identifies specific gene mutations, proteins, chromosomal abnormalities, and/or other molecular changes that are unique to YOU and YOUR prostate cancer.

There are two main types of genetic tests used in prostate cancer:

  • Germline or hereditary genetic testing, which is conducted via blood or saliva and identifies inherited gene mutations in the body. Germline mutations are present from birth and can be shared among family members and passed on to subsequent generations. Results can identify whether you could be at risk for another type of cancer or if your family members may need genetic counseling and testing to guide their own cancer risk.
  • The second is somatic or tumor genetic testing, which is performed through testing tumor tissue or by testing cancer cells/DNA extracted from blood to identify gene mutations that are unique to the cancer itself. It is also commonly referred to as genomic testing, biomarker testing, or molecular profiling. Somatic mutations are NOT inherited and are NOT passed on to subsequent generations or shared among family members.
  • Depending on your history, your doctor may order one–or both–of these types of tests.

So why do the test results matter?

Both germline and somatic mutation testing can identify the presence of certain genetic mutations that may help to guide your treatment plan, and germline testing specifically can inform cancer risk for you and, potentially, family members.

  • In some cases, mutations can indicate that a newer approach, such as targeted therapy or immunotherapy, may work better for you.
  • Results of these tests may also help you to find a clinical trial that may be appropriate for your particular cancer.
  • And, genetic testing results could also show that your cancer has a mutation or marker that may prevent a certain therapy from being effective, sparing you from getting a treatment that won’t work well for you.

How can make sure you have had essential biomarker testing?

  • First, always speak up and ask questions. Remember, you have a voice in YOUR prostate cancer care.
  • Ask your doctor if you have had or will receive genetic testing, including germline and somatic testing, and how the results may impact your care and treatment plan.
  • Ask whether your family members should meet with a genetic counselor or undergo testing to help gauge their risk of developing prostate cancer.
  • And, finally, bring a friend or a loved one to your appointments to help you process and recall information.

All right, let’s meet our guest today. Joining us is Dr. Jane Meisel. Dr. Meisel, welcome. Would you please introduce yourself?

Dr. Meisel:

Absolutely and thank you so much for having me. My name is Jane Meisel and I’m a medical oncologist at the Winship Cancer Institute at Emory University. I’ve been here for about six years and before that, I did my training in Boston and at Memorial Sloan-Kettering in New York. And I specialize in breast cancer and have had a lot of great opportunities to treat amazing patients and participate in a lot of research.

And I’m looking forward to having this discussion with you today.

Katherine:

Thank you for joining us, we really appreciate it. So, let’s start by discussing the latest developments in treatment and research updates. Are there recent developments you feel breast cancer patients should know about?

Dr. Meisel:

Absolutely and I think it’s really been such a remarkable time because even during COVID, a pandemic, where I think a lot of people worried that research efforts would shut down or stall. We’ve still seen the approval of a number of drugs in the past year that’ve really already markedly changed lives. And a lot of important findings that’ve come out of other trials that they have opportunity to do that as well.

I think some of the biggest information that was presented at our most recent large meeting, which was the American Society of Clinical Oncology, or ASCO National Meeting in 2021, were a few things that pertain to the metastatic breast cancer population. One was two studies, the PALOMA-3 Trial and the MONALEESA-3 Trial, which looked at a class of drugs called CDK4-6 inhibitors along with anti-estrogen pills in metastatic estrogen-positive breast cancer.

And really confirm for patients that not only do these drugs improve the amount of time that people can stay on treatment before their cancer progresses, but actually improve how long people live. Even when they’re used very, very early on in treatment, they impact survival down the line for many, many years. So, it really confirms for physicians like me that this class of drugs should be used as the standard of care and first line for patients with estrogen-positive stage IV breast cancer, and I think that’s important for patients to know. Along those lines, there a drug called sacituzumab govitecan, or Trodelvy, which is a much easier to say name.

Katherine:

Yes.

Dr. Meisel:

A new antibody drug conjugate in triple-negative metastatic breast cancer. And we’ve also seen, since this drug was approved last year, it has markedly changed the lives of many patients with triple-negative disease. And the study called the ascent trial, which is what led to that drug’s approval was studied further and some of these additional results presented at ASCO this year.

And found that this drug not only improves again, how long people get before they have to move on to another treatment, but actually improves how long people live as well, even when given later on in the course of therapy. So again, really encouraging use especially in triple-negative metastatic disease, which is hard to treat. And I think another study that’s really worth patients and doctors taking a hard look at, was actually a study that looked at patient outcomes and patient experience. This is a study that actually talked with metastatic patients and gathered their views on treatment related adverse effects.

Talked to patients about what adverse effects they were experiencing from drugs. How they managed those adverse effects. And found that most patients, over 90%, will be willing to talk about reducing the dose of drugs or changing dosing schedules, in order to improve quality of life. And I think that’s really important because a lot of times, the doses of drugs that get approved are the doses that are the highest doses that don’t cause extreme toxicity. But sometimes people can have effective, really good outcomes on lower doses and have much better quality of life.

And in metastatic breast cancer where really the goal often times is to help people live as long as they can, but also as importantly, as well as they can, be able to have those open-ended conversations between patients and doctors about what’s really impacting your quality of life now and how can we make that better is important. And this study I think really highlighted that both for patients and physicians, how important that back and forth is to having a successful outcome. Both in terms of how life is lived, but in terms of quality of that life.

Katherine:

Right. Right. How can patients stay up to date on developing research?

Dr. Meisel:

It’s so interesting because there is so much coming out and I think it can be hard to figure out what Phase I study that looks exciting is really going to become something, versus what really could be important in my treatment today. And what I always tell people is actually, the NCI website. So, the National Cancer Institute, has a phenomenal page looking at advances in breast cancer research. So, if you Google “NCI advances in breast cancer research,” there’s a great page that comes up. And it’s impressively up to date and I think very patient-friendly.

Breaks things down into early stage and metastatic and then in the metastatic section, talks about estrogen-positive, HER2-positive, triple-negative, which we can talk about more today but are the three big subtype of metastatic disease that dictate how we treat them. And then have links to all the different research updates and talk about what these drugs are, what the classes are and what the settings are in which they’re studied.

And so, I think that’s a really great first stop and then the links can take you to all different stuff that’s on the page that you might want to look into more in depth. And then also, the Breast Cancer Research Foundation, which is a phenomenal organization. They have a great website, too and if you click around on the website, you can see not only who they’ve donated money to that’s doing promising research, they also have podcasts, they have a blog with science and research news. I think that’s a really great site for patients to use to stay updated.

Katherine:

Let’s shift gears for a moment and talk about another time sensitive topic, COVID. Now that vaccines are available, are they safe and effective for breast cancer patients?

Dr. Meisel:

Yeah, I think the short answer to that is yes, absolutely. I’m encouraging all my patients, no matter what their treatment status is to go ahead and get vaccinated. And we are seeing now this third surge in COVID with cases rising all over the country, and really among unvaccinated populations. And with the delta variant being more transmissible, I think it’s all the more time, even if you haven’t considered vaccination up until now, to really go ahead and strongly consider getting a vaccine.

I think some of the hesitations that some of the people have talked to me about is that there were not a lot of active cancer patients, if any, included in the initial trials. And whereas that is true, it’s still the case that now, so many cancer patients have been vaccinated. We haven’t really heard about adverse effects in vaccination being something that’s higher in patients who have cancer who are on active treatment. I think the one challenge is, if you have a compromised immune system because of cancer treatment, there’s the possibility that you might not mount the same immune response to the vaccine as someone who doesn’t have cancer or isn’t getting active treatment.

So, while I would say yes, definitely get vaccinated, I would also at the same time encourage caution in saying, because you might not mount the same, 95 percent or whatever immune response, it may still be a good idea to wear a mask when you go to the grocery store, taking those precautions because no one really knows what’s coming and it’s better to be safe than sorry. But I think we will get a lot of information as the months go on about, do we need boosters? Who might need boosters more soon than others and some of that will get clarified for us, but my short answer would be yes, vaccines for all.

Katherine:

Excellent, that’s very helpful.

Dr. Meisel:

Thank you.

Katherine:

Since this webinar is focused on metastatic disease, would you define metastatic breast cancer for us?

Dr. Meisel:

Absolutely. And I think metastatic breast cancer is one of those terms that as doctors, we throw around a lot and often times don’t stop to check understanding as to what that means.

And what metastatic breast cancer is and means, is breast cancer that is spread outside of the breast and surrounding lymph nodes to another organ system. So, metastatic breast cancer, some of the most common places where it spreads are to the bone, to the skin, to the lungs, to the liver, to the brain. There are other places it can spread to. I’ve seen it on the ovaries, in the GI tract. But basically, when breast cancer spreads outside of the breast and surrounding lymph nodes to another organ system, that’s when we consider it metastatic.

Katherine:

How can a patient ensure they are getting an accurate diagnosis?

Dr. Meisel:

Another good question. And I think the most important thing when you’re considering whether or not you have a diagnosis of metastatic breast cancer is to get a biopsy of that metastatic site. So, you wouldn’t want to assume, just based on a CT scan that shows something in the bone that you have metastatic disease. Ideally, we would biopsy that spot or some spot that was indicative of metastatic disease to actually prove that there is metastatic cancer in that distant site.

Because sometimes it’s nothing. Sometimes you get scans and a little bone abnormality, maybe a scar from a prior fall. And then also, sometimes if it is metastatic, sometimes the breast cancer, the hormone receptor status, for example, can change from the primary site to the metastatic site. And that might impact treatment. So, it’s important to both get a metastatic biopsy to confirm diagnosis. And also, to understand what the treatment plan might be. And I think also for patients, just to make sure that you understand what your stage is, ask your doctor.

Say, what is my stage? Because sometimes doctors think people understand and they don’t actually, so checking that understanding is important. But if your doctor or provider is not actively checking your understanding, you can check it with them to make sure that if you are metastatic or have Stage IV disease, which is another way we define metastatic or talk about metastatic cancer, that you make sure you have the definition right.

Katherine:

Right, right. So, once someone has been diagnosed with metastatic disease, are there key tests that’re used to help understand how their disease may behave and progress?

Dr. Meisel:

Absolutely. So, I think the first thing as I said is that metastatic biopsy. Another thing that’s very important is understanding the hormone receptor status and the HER2 status of the breast cancer. And probably for a lot of you listening, if you have listened to metastatic breast cancer webinars before or maybe know someone or have had a diagnosis yourself, you’re well versed in this. But for some who may not be, I think a quick overview is maybe helpful. Breast cancer can be divided into three different subtypes. So, triple-negative, estrogen-positive or HER2-positive. And estrogen-positive breast cancer is the most common kind.

That tends to be driven by hormones and often treated with what we call, endocrine therapy. So, anti-estrogen pills, things like Tamoxifen or aromatase inhibitors are examples of that. And that’s one kind. And then there’s HER2-positive breast cancer, which is a type of breast cancer that over expresses a marker called HER2. And we now, since we know about that marker, have been able to develop a lot of different treatments that target HER2 selectively.

And can be used to treat that subtype. And then triple-negative is basically estrogen-negative, progesterone-negative and HER2-negative. And that type of breast cancer traditionally was treated essentially only with chemotherapy. But now we’ve had some breakthroughs, which we’ll talk about I think later in this program talking about immunotherapy and more targeted therapy for that. But those subtypes help determine how we treat patients. And it also can sometimes predict behavior.

I would say one of the other things that helps us predict behavior of metastatic disease is, if a patient had early-stage disease before, how quickly they developed metastatic disease. So, for example, someone who develops estrogen-positive metastatic breast cancer 12 years out from their original diagnosis is statistically more likely to have a slower progressing course of disease than someone who develops triple-negative metastatic disease very soon after their initial treatment. So, I would say that’s the primary thing we look at in terms of determining treatment plan and then predicting overall course.

Katherine:

Right. Well, let’s talk about treatment options for advanced disease.

Can you review the types of treatments available for metastatic breast cancer?

Dr. Meisel:

Absolutely. And what I’ll do is, I’ll give you a broad overview and then because there’s so much and this is such a rich environment, I mean, I give hour long lectures just about the treatment of metastatic triple-negative breast cancer to our fellows. So, there is so much meaty information here. But I’ll give an overview with some key buzzwords so then people can go look up things that matter more to them or interest them more. So, as I said, we start with thinking about, is this hormone receptor-positive or estrogen-positive breast cancer? Is this HER2-positive or is this triple-negative? And those factors really send us down different paths.

So, if someone is estrogen-positive, I had mentioned before the PALOMA and MONALEESA studies showing that CDK4-6 inhibitors, which is a class of drugs that the first one was approved in 2015 and then two others have been approved subsequently. So, relatively new drugs. But those drugs, which are pills, added to traditional anti-estrogen therapy which would be aromatase inhibitors or fulvestrant.

Are often great first-line options for these patients. And people can do well for years on just that alone, with estrogen-positive metastatic breast cancer. On average, about two years before people progress and need something new. And then after that, there are lots of trials ongoing looking at different ways in which an estrogen-positive breast cancer might progress on that regiment and how do we target that. So that there are multiple other anti-estrogen options down the line that people can use in estrogen-positive breast cancer before they need to even think about going on to something like chemotherapy.

So, really lots and lots of options for those patients, but probably starting with a CDK4-6 inhibitor plus anti-estrogen combination. And then in HER2-positive breast cancer, typically the first-line treatment would be what we call monoclonal antibodies directed at HER2. So, something like Herceptin and Perjeta, which you may have heard of. And often combined with chemotherapy. But again, this is one of those areas that is also very, I think the art of medicine is very important and patient dependent.

Some of these regiments depend a little bit on patient’s age and other medical problems and desires, whether to include chemotherapy along with that frontline anti-HER2 regimen. Or whether to think about something like anti-estrogen therapy if the patient is HER2-positive and estrogen-positive. And then there are a lot of other different things we’re also using in HER2-positive disease after patients progress on that initial therapy, so there are what we call, antibody drug conjugates, where a chemotherapy like drug is attached to an antibody that then brings the chemo to the HER2-positive cell and allows for chemotherapy penetration more directly.

And then a class of drugs called tyrosine kinase inhibitors, which are oral drugs that get directed at HER2. So, another really exciting area to treat and a place where we’ve seen so many advances. And then in triple-negative breast cancer, I’d mentioned that chemotherapy has really been the mainstay of treatment historically because there weren’t great targets. But recently we’ve seen that immunotherapy, along with chemotherapy drugs like Keytruda, which you may have heard of.

Or atezolizumab, which is Mesenteric, can be used along with chemo and patients that overexpress a molecule called, PDL1. And that can actually include not just how long patients spend on the first treatment, but how long they live. So, we’re seeing a lot of triple-negative patients being great candidates for immune-based regimen now. And then for patients who have inherited a BRCA gene mutation, which many of you may have heard of. That gene mutation can actually predispose a triple-negative patient to be more receptive to a class of drugs called PARP inhibitors.

So, drugs like olaparib (Lynparza) or talazoparib (Talzenna) are new drugs that’ve been approved in the last couple of years in triple-negative metastatic breast cancer for patients who carry a BRCA1 mutation or BRCA2 mutation. And then there are also antibody drug conjugates in triple-negative breast cancer as well. The Trodelvy that’s been approved and then of course others that are in clinical trials currently. So, as you can see, it’s complex. I mean, the treatment of metastatic breast cancer is complicated. And so, it’s important I think to really be able to have a dialogue with your provider about what they’re recommending for you and why.

And I think there are often lots of options. And so, as much as you can make your doctor aware of what matters to you in terms of what side effects are you most afraid of or would you like most to avoid, what dosing schedules would be idea for your schedule for the rest of your life. So that you can deal with taking kids to school or the job that you’re currently working on or whatever, I think helps your doctor help you come up with the right regiment for you.

Katherine:

Yeah. Yeah. So, what factors are considered when deciding on the best treatment approach for an individual patient?

Dr. Meisel:

So, I think certainly the tumor type that we were talking about. Is it estrogen-positive or HER2-negative or HER2-positive? I think response to past treatments, both in terms of if someone has had metastatic disease for a long time and has had a few treatments already, how long did they respond to those treatments and how completely did they respond to those treatments. Did they have stable disease for a while or did their cancer actively shrink?

And then I think other than that, it would be some of the things I touched on. Side effect profiles. Do patients have pre-existing neuropathy from other chemotherapy? If so, maybe you want to avoid a regiment that causes more neuropathy. Schedule. Some patients, it’s really important to be on a certain schedule, as opposed to a different schedule. I think whether there are clinical trials available instead of whatever the standard of care regiment would be is also important.

Because for some patients who are interested in pushing the envelope or who might be a great candidate for a particular trial, if there is one that they’re a candidate for that’s not horribly inconvenient from a logistics standpoint, then trials I think are also a great option to consider. So, I think from an effectiveness standpoint, you want to think about the tumor type response to past treatments. And then potentially, if the patient has had, what we call genomic profiling, where the tumor has been sent for basically genomic analysis, to see what genes might be mutated in the tumor that could potentially drive a response to a newer, different therapy.

All those things can be taken into account as we think about the cancer. But then there is the patient specific factors, and I think those would be mainly side effects, schedule, clinical trials and desire or not to pursue those. And then, just what the patient’s perspective is on the plan that you’re offering them.

Katherine:

What is biomarker testing and how do results impact treatment options?

Dr. Meisel:

Great question. So, I think people often confuse germline mutations and somatic mutations. So, I’ll talk about that a little bit as we talk ab out biomarkers. So, I think biomarkers in general are factors within the tumor that allow us to make treatment decisions. So, if a biomarker in the tumor can predict response to a certain type of treatment, we want to know what that biomarker is so we can better treat the patient and more elegantly design a regimen. So, for example, having an estrogen-positive tumor, estrogen positivity is a biomarker suggestive of response to anti-estrogen treatments, which is why we give anti-estrogen therapy to ER-positive breast cancers.

But more recently, we’ve been able to move a little bit beyond estrogen, HER2- and triple-negative as our subtypes and think a little bit more in some patients about more sophisticated biomarkers. And that’s where somatic mutation testing comes in. So, there are germline mutations, which are inherited mutations that’re present in every cell in your body. So, for example, if your mother was a BRCA mutation carrier and based that BRCA mutation down to you, you would have a germline BRCA mutation. So, your cancer would carry a BRCA mutation, but so would every other cell you have.

And that’s a biomarker. That would make you a candidate for something like a PARP inhibitor. But in cancers, which the genes in the cancer have gone awry by definition, there are often other biomarkers within that tumor that may make you a candidate for certain treatments. And so, those mutations that arise in the cancer itself are called, somatic mutations. Those are mutations in the tumor, can’t be passed down to your offspring or anything like that and were not inherited by your parents. But mutations that’ve accumulated over time as these cancer cells have gone awry.

And so, genomic testing, or biomarker testing can be done often on a metastatic specimen. So, to be specific about it, say you had a metastatic breast cancer to the liver. You could have a liver biopsy done and that tissue from the liver biopsy could be sent for genomic testing. There are a lot of companies that do this and there are also some larger cancer centers that actually do in house testing for genomics. So, this testing can be done and what it does then is, it helps you determine, do you have a biomarker that predisposes you to a certain treatment.

So, if that metastatic liver tissues, for example contained high levels of PBL1 expression for example and you were triple-negative, that would say to your doctor, “Ooh, this is a great candidate for immunotherapy along with chemotherapy.” Or if you’re estrogen-positive, for example, and your tumor contains a mutation in the gene called PIK3CA and that might make you a candidate for a drug called, alpelisib (Piqray). So, these mutations could often be paired to a drug or treatment options, or sometimes to a clinical trial to allow patients to come take advantage of more targeted therapies.

That sometimes, because they’re targeted, have fewer side effects than drugs that are a little more discriminate.

Katherine:

Marie sent in this question prior to the program. Are there some genetic tests that’re more accurate than others?

Dr. Meisel:

That’s a good question. I would say most genetic testing platforms have been heavily vetted and approved by national organizations and laboratories that’ve been tested multiple times before they’re allowed to be marketed. So, I wouldn’t say that one genetic testing program is necessarily better than another. I think that any of the commercially available platforms that’re used are probably pretty accurate.

Katherine:

Okay. How does symptom management play into the treatment decision?

Dr. Meisel:

I was just going to add one thing to that, if that’s okay. I was going to say that I think it’s important when you’re using genetic testing platforms though to know what you’re testing for. So, there are some platforms that will just test for say, the three most common mutations in BRCA1 and BRCA2 that Ashkenazi Jews have.

And so, if you get that testing back and you’re negative, you might think oh, I don’t have a mutation in those genes. Well, we know from that testing, just as an example, is that you don’t have a mutation in those three alleles of that gene. But if you haven’t had full gene sequencing, you could have a mutation somewhere else in that gene. So, I would say all genetic testing that’s commercially available is probably pretty accurate. But it is important when you get testing done to know what you’re testing for and what you’re not testing for so you can interpret your results accurately. And genetic counselors, as well as your doctors can help you do that.

Katherine:

Right, right. Okay, I’m going to ask the question, this question again. How does symptom management play into the treatment decision?

Dr. Meisel:

I think symptom management is huge, because like I said and I tell this to all my patients at the outset of treatment that most of the time, metastatic breast cancer becomes a chronic diagnosis for a patient. You’re dealing with it, essentially like a chronic illness for the rest of your life. And you’re on some form of treatment for the most part, for the foreseeable future.

And so, making sure quality of life is as good as it can be is critically important. And I think symptom management is a huge part of that and we know that if we can treat and manage symptoms well, people can live better and often live longer because then they can stay on treatment for more extensive periods of time comfortably. And so, I always encourage patients, don’t be a martyr.

Don’t think you have to just bounce in here and tell me everything’s okay if it’s not okay. If you’re having symptoms and side effects from treatment, or from the cancer, I want to know about them so that we can really aggressively manage those symptoms just like we’re aggressively managing the cancer. A lot of times oncologists can do that on their own. We are pretty well versed in managing a lot of symptoms and side effects.

But a lot of times also, there are teams of doctors either who do palliative care or here at Emory, we call it supportive oncology where they are specially trained in things like pain management and managing more common side effects like nausea, constipation, diarrhea, appetite suppression, that can go along with cancer and with treatment.

And then they often will co-manage patients with us as well, just to make sure there’s that really strong focus on maintaining as much of a low symptom burden as possible.

Katherine:

So, you mentioned earlier, clinical trials. When should patients consider participating in a trial?

Dr. Meisel:

I think it’s a great question and I think the answer is really, almost any time. There are trials in every setting. So, I think one of the common misconceptions about clinical trials is that you really only should be in a clinical trial, or your doctor might only mention a clinical trial if they don’t have other options for you or if you’re really in stage. And I think that perception is changing. But I think the reality is that there are clinical trials in every setting.

So, we have clinical trails looking at prevention of breast cancer. Clinical trials looking to optimize early-stage treatment of breast cancer. Clinical trials looking at secondary prevention, so once you’ve had breast cancer, how can we reduce your risk of recurrence. And then lots of clinical trials in the metastatic setting both for patients who are initially diagnosed with metastatic breast cancer.

And then in second, third, fourth line and even for patients who have had tons and tons of additional therapy that we’re looking at new drugs for. So, I think at almost any juncture where you’re making a treatment change, it’s probably appropriate to say, would there be a clinical trail that you can think of that would be good for me in this setting? And it may be that there’s a one that’s 12 hours away, and it’s not convenient for you or feasible.

And it may be that your doctor doesn’t necessarily know of one but then that prompts them to ask a colleague who may be more involved in clinical trial design and development. Or it may be that there is one, but you ultimately choose not to pursue it because you have a different option. But I think it’s always appropriate to ask, would there be a trail for me? Because if there is, then maybe that opens up an option you hadn’t thought about before.

Katherine:

Sure. For patients who aren’t familiar with the stages of clinical trials, would you give us a brief overview of the stages?

Dr. Meisel:

Yeah. Absolutely. So, in terms of clinical trials that’re being done in humans, we talk about Phase I, Phase II and Phase III typically. So, a Phase II clinical trial is typically an earlier stage trial.

Looking at either a drug that has not been tested in humans before or a drug that has not been tested in a particular combination in humans before. And so, those trials are done only in select institutions, usually academic institutions as opposed to private hospitals. And they often have what’s called a dose finding phase and then a dose escalation phase. So, the earliest part of those trials is actually looking at, what is the safest dose to give to patients?

So, they start the first patients at a low dose of the compound. And if those patients do well, the next patients that’re enrolled get enrolled at a slightly higher dose. And then up until they reach the highest dose they can find where people are tolerating it and doing reasonably well. And in those Phase I trials, doctors and investigators are also evaluating efficacy, is this drug working. But the primary goal of the early phase trial is actually to find the right dose to then study in larger groups. And so, if they find the right dose and there’s good biological rationale for the compound, then the trial would go on to a Phase II.

Which might be just what we call single arm Phase II study, where every patient is getting that experimental drug. And we monitor them to see, is the drug effective, or is it less effective than the standard of care? Or sometimes they’re what we call, randomized Phase II trials where patients are randomized to either get the experimental drug, or to get what the standard of care would be in that situation. I think a lot of people get afraid about the idea of a randomized trial because they’re afraid they’re going to be randomized to a placebo. And that is really not done in the metastatic setting, because it wouldn’t be ethical to give a patient with active cancer a placebo.

So, usually the randomization would be either to the study compound or to a standard of care drug. And then if things look good in a Phase II trial, then a Phase III study is done which is usually what the FDA requires to allow a drug to go on and be administered outside of a study for approval. And those Phase III trials tend to be larger studies that’re done in larger groups of patients with more statistical validity because of their size, to determine, is this drug really better than the standard.

Katherine:

Right. We have another question we received earlier, this one from Eileen. She asks, how will I know whether my treatment is working?

Dr. Meisel:

That’s a really good question. So, I think for patients who have symptoms from their cancer, they often will know the drug is working because their symptoms improve. Say if you have lung metastases and you are short of breath and your shortness of breath gets better. That’s a really good sign that the treatment is working. I would say that often what we are doing, and it depends a little bit on the regimen and what the patient is getting and how often they’re coming in.

But we’re checking labs as well and sometimes there are lab abnormalities when a patient is diagnosed with metastatic cancer that can then improve over time. So, for example, if someone has a heavy burden of bone involvement with breast cancer, there’s a lab value called the alkaline phosphatases that will often be elevated. If that starts elevated and comes down, that’s a really good sign. And some of their liver function tests that we check and if a patient has liver metastases, we often will see those come down if a patient is responding.

There are also, what we call tumor markers that we can check in patients with metastatic breast cancer. Those would be proteins in the blood basically that can be made by the breast cancer in abundance. And those are called CA27-29 and CA15-3. Some doctors check both of them. Some will just check one depending on which one their laboratory at their institution is running. But typically, I will check those at diagnosis of metastatic disease. And then if it’s elevated, I know it’s a good marker to follow for my patient. And then I’ll follow that monthly or every three weeks, depending on when the patient is coming in to see me.

And if I see that marker start to go down, it’s not an absolute, but it can be a good early indicator of improvement with the treatment. And then I think it varies a little bit from practice to practice and based on patient preference. But often there will be scans done when a patient is initially diagnosed to determine the extent of the disease. So, usually a CT scan of the chest and the abdomen and the pelvis or a PET scan, which some of you may have heard of. Either one of those is good.

And that can be done about every 12 weeks usually in the beginning, to make sure a patient is responding and once you feel confident that they are, those can be done sell frequently. So, I would say the scans and the lab work and then the patient’s overall condition are usually the way that we look to see, are we having a response or not.

Katherine:

We’ve talked about several key tests. Some patients may be confused about whether they’ve received these tests. So, what questions should they ask their physician to make sure they’re getting appropriate testing?

Dr. Meisel:

I think it’s probably useful because not everybody needs every test, and I think there are often things you hear about online or from friends or even in a webinar like this, and there may be a good reason why you haven’t had that particular test. So, I wouldn’t assume that if you haven’t had everything that we’ve talked about today even, that someone’s made a mistake or that you need that and aren’t getting it. But I would ask. I think it’s always helpful to know more, knowledge is power. And so, if you have never had a CT scan or a CA27-29 level or a genomic testing.

I think it’s not a bad thing if you’re curious about it, to just ask your treating team, “Hey, I heard about genomic testing, is there a reason I haven’t had that? Or have I had that?” Maybe you have, and they called it something else. I think it is complicated, but I think it helps to understand what you’ve had done and what you haven’t had done. And sometimes, asking about something like that may prompt the team to do things that my benefit you.

Katherine:

Before we wrap up, Dr. Meisel, how do you feel about the future of breast cancer research and what would you like patients to know?

Dr. Meisel:

Yeah, I think one of the most important things and I actually said this to a family this morning where a loved one had received a new diagnosis of metastatic breast cancer is that the field has evolved so much over the past five years. I think often when people get a diagnosis of metastatic breast cancer, it’s the most dreadful feeling they ever had. They remember that day for the rest of their lives. But we are seeing so many people do so well for so long now and tolerate treatments well because the treatments are better tolerated.

And there’s I think more attention being paid now to symptom management. That people really can do so much better than they’ve been doing. And I would say really, every year, even every six months, when I go to give a lecture on a topic in metastatic breast cancer, I can’t just give the same talk. I’m always having to update my slides because there’s so many new things coming out, so much new research on the table.

And we’re seeing so many new drug approvals now that we’re starting to unlock some of these new mutations and reasons for progression and understanding new drug classes. So, really think it is a bright time to be in breast cancer research, and there’s never been a better time to be a patient if you have to fall into that category.

Katherine:

It all sounds so promising, Dr. Meisel. Thank you so much for joining us today.

All right, let’s meet our guest today. Joining me is Dr. Maha Hussain. Dr. Hussain, would you please introduce yourself? 

Dr. Hussain:

Sure. Thank you, Katherine. 

It’s my pleasure to join you. And to the audience, nice to meet you all virtually. My name is Maha Hussain. I am a genitourinary medical oncologist with a focus on prostate cancer and bladder cancer. And I am a professor at Northwestern University Feinberg School of Medicine, Department of Medicine, and endowed professor there. And I also serve as the deputy director for the Robert H. Lurie Comprehensive Cancer Center of Northwestern University. 

Katherine:

Wonderful. Thank you so much for taking time out of your busy schedule to join us today. 

Dr. Hussain:

My pleasure. 

Katherine:

I’d like to start by asking about developments in prostate cancer research and treatment. Experts recently gathered at the annual American Society of Clinical Oncology meeting, also known as ASCO, to share their research. 

So, what were the highlights from that meeting that you feel patients should know about? 

Dr. Hussain:

I think probably perhaps I can focus on two major – what I would consider major highlights, and those were the results from two randomized Phase III clinical trials. 

One of the trials is called the VISION trial. And the VISION trial was a Phase III randomized trial evaluating lutetium-PSMA-617 treatment in patients with metastatic castration-resistant prostate cancer. And the delightful thing about this study is that that study was positive. The PSMA story has been really going on for a few years now. And there’s the PSMA for purposes of scans, imaging, to assess the cancer. And the FDA just approved a PSMA PET imaging this year. 

I think it was in May when it was approved. And that would help better define if the cancer is spread or not, and it help with the decision regarding treatment. But the second part is treatment purposes, so identifying the cancer location and trying to attack it with a specific sort of targeted attack to the tumor is really important. 

And so, the FDA is currently looking at this particular agent. And I am hopeful that we will hear soon from the FDA, hopefully before the end of the year, and maybe – who knows? – maybe by summer, middle summer or end of summer. Because I do think that would be a major benchmark in there. And so, that’s one thing. 

The other clinical trial that I thought was interesting from a data perspective – and for disclosure, I am one of the investigators on this study. And this was an intergroup Southwest Oncology, or SWOG, sponsored clinical trial. So, it’s a federal study that Dr. Aggarwal presented. And this was a study that was aiming at maximizing, again, the anti-tumor therapy with the use of a drug which I call is the younger brother of abiraterone. 

So, abiraterone is a drug that is FDA-approved and has been around for several years right now for both castration-resistant prostate cancer and certainly hormone-sensitive metastatic disease. And so, TAK 700 (Orteronel) is a younger brother, I call it, of abiraterone. And one of the potential advantageous when this trial was designed was the fact that you don’t need to use prednisone. And the trial was completed. It was a national clinical trial. And what was interesting is that there is certainly what appears to be a potential benefit, but not in terms of the conclusive based on the way the study was designed.

Having said that, what I thought was remarkable is that patients who basically were only on the control arm was LHRH therapy, so this could’ve been like Lupron, Zoladex, or something like that plus bicalutamide, which is what we call combined androgen deprivation. And that was sort of like the strongest control arm we could do at the time when the trial was designed. 

Remarkably, the patients who were on that arm had a median survival of basically 70 months. That’s the median. That’s the bell-shaped curve with the number in the middle. Seventy months is probably the longest ever in any other randomized trials in this disease space, in the hormone sensitive space. So, that tells us is that men are living longer with prostate cancer, even though it’s metastatic disease; and, yes, it’s not necessarily curable, but men are living longer. And it’s a function of all of the better treatments that are supportive care and everything that was going on.  

And so, the control arm, as I mentioned, was the 70.2 months. The actual experimental arm was about 81.1 months. And again, I don’t know where things will go from this. Obviously, I’m not the sponsor not the FDA. But the point here is that men are living longer, and so wellness and health become even more so important than we ever did. And as I tell my patients, every day you’ll live longer. The odds of living longer is there because of better treatments coming on. 

So, to me – not to take too much time from the interview – to me, these were the two highlights: new, approved – I’m sorry, new treatment that I’m hoping will be FDA-approved and, obviously, the fact that men are living longer.  

Katherine:

How can patients keep up to date on the research that’s going on? 

Dr. Hussain:

I’m a bit biased, obviously. I’m a member of ASCO. 

And what I would recommend to my patients is to look at the cancer.net website. The cancer.net is a website that is an ASCO-generated website specifically for patients and families to review. It is vetted. The committees are not run just by physicians, oncologists, a multidisciplinary team, but also patient representative. So, the lingo and the presentation are lay-friendly, I call it, there. 

The other part I would say, the NCI website, and the American Cancer Society, the American Urological Association. I would say there’s a lot of stuff on the media. The difficulty is vetting what is sort of fake, what is not so accurate, or bias versus there. I also think that the NCCN has also some resources for patients. 

And one thing I always tell patients: explore, look, but make sure that you talk to your doctor about the meanings of everything because sometimes it can be not – it could be misleading, I should say, or maybe not very clear on what the implications are. 

Katherine:

Right. One thing that’s a topic on the mind of many people right now is COVID. 

Dr. Hussain:

Yeah. 

Katherine:

Is the COVID vaccination safe and effective for prostate cancer patients? 

Dr. Hussain:

The answer is yes and yes. So, I have to say, by default, I deal mostly with older men. Age brings in other comorbidities. And certainly, while I see all kinds of shades of gray in terms of the disease extent, going all the way from newly diagnosed all the way to end-stage disease, the bulk of the patients I end up seeing tend to have more systemic disease and have other issues going on. And I have to say, surprisingly, less than a handful of my patients had the infection. 

Only one required hospitalization with supportive measure, but not even needed incubation; however, he needed a lot of CPAP and other respiratory support. I’m not aware of any of my patients or my colleague’s patients who deal with prostate cancer that have died from COVID. So, I would say that’s the good news and that we have not seen a big hit in the population that I deal with. 

I also know that I would say 99.9 percent of my patients have opted to be vaccinated, and they have tolerated the vaccine just fine. There’s only one case, which I actually even saw just this week, who had been vaccinated but have a very, very severe end-stage disease with significantly compromised bone morrow, who got infected but hospitalized for a few days and is recovering. 

And so, I would say just by the pool of patients I see, my answers are yes and yes. 

Katherine:

Very good. Thank you. 

Dr. Hussain:

And I would encourage all the audience to go get vaccinated. I myself am vaccinated. And I’ve advised all my family members to be vaccinated, just to clarify that too. 

Katherine:

Good. Good to know. Dr. Hussain, we’re going to spend most of this conversation talking about advanced prostate cancer. But before we move on, would you give us a brief overview of the stages of prostate cancer? 

Dr. Hussain:

Absolutely. So, with any cancer, we count sort of like four stages. But I would say in prostate cancer the biggest thing is when the cancer is newly diagnosed, which could be confined to the prostate or locally advanced, meaning the cancer has gotten outside the capsule of the prostate but still within that pelvic region. 

There is the group of patients who have pelvic lymph nodes at time of diagnosis. And of course, that is the patients who have systemic disease, which would be technically stage four. Now, the systemic disease implies any abnormality that is found on scans that is beyond the public region. So, that could be lymph nodes in the back of the belly. That could be thoracic lymph nodes. That could be neck nodes. That could be lung lesions, of course, or bone, or liver. 

Now, the most common area where the cancer goes to is really – when we talk about metastatic disease – is the bone. And then lymph is another area where the cancer goes to. Prostate cancer that is confined to the prostate is curable in the vast majority of patients. There is a category of men who undergo surgery or radiation, and then their PSA begins to go up afterwards. 

And this is what we call biochemical relapse. And this is a situation where we know that, in all likelihood obviously, especially of the patients who have had their prostate out, that the cancer has spread. With the current imagine, a good chunk of times, we do not find anything because we’re able to pick up PSA that goes from undetectable to 0.2 to 0.3, but there’s not enough cancer to show up on the scans. We’re hoping, obviously, the better scans, the PET Axumin scan, the PSMA scans are going to help us to identify sites of metastases. 

But this is a group of men where if there is no cancer visible and the only thing we’re dealing with is PSA that’s going up, if they’ve had surgery, then there’s room for what we call salvage therapy with radiation and hormonal treatment. The case is a bit different if there’s only just the prostate – if radiation was given previously. And of course, we talked about metastatic disease. 

Katherine:

Yeah. Once someone has been diagnosed, what tests are used to help understand the aggressiveness of their disease and their overall prognosis? 

Dr. Hussain:

Well, I think there is different basic things, as in, what was the extent of the cancer? How did it look under the microscope? And what is the PSA levels? So, these are the general things. There are different sort of genomic panels that the urologist will use to kind of decipher and other things to kind of help with figuring out aggressiveness and things like that. What I would say is this, is a patient who is diagnosed and has a cancer, and at a minimum has what we consider a Gleason 7 prostate cancer – so, that’s the scoring system that is done with the original Gleason score, or the new patterns where it’s talking about intermediate risk to high risk – to me, this is a cancer that needs to be treated. 

And again, that’s all to do with if a person has other comorbidities, they have some other terminal condition that’s a separate story. But talking generically, that would be when we would recommend. And these are the patients that are generally not seen by the medical oncologist. They’re seen by the urologist, and then they can refer them to radiation oncology also for consultation. 

Katherine:

Now that we understand how test results can help inform a patient’s cancer and how it may behave. Let’s discuss how they can affect treatment options for men with advanced disease. First, let’s do a brief review of the treatment types currently available. There’s hormone therapy, right. What else? 

Dr. Hussain:

Perhaps, it’s simpler if we focus on advanced disease, specifically metastatic disease. 

So, if that’s the deal, then the backbone of treatment is hormone treatment. And it really is. We call it hormone, but technically it’s an anti-hormone. What we’re trying to do is shut down the hormonal pathway that stimulate the testes, which is the factory that makes testosterone. So, we are looking at shutting down testosterone production from the testes in order to starve the cancer. 

Now, the male hormone is produced predominantly – somewhere about 95 percent of it is made by the testes, and then there are about 5 percent-ish that comes from other sources. These are, again, male hormones like the adrenal gland and so on. And there was a while ago some research – I want to say from the MD Anderson crowd, but this is two years ago – that suggested also that the tumor may start to make sort of in-house production of male hormone to support itself. 

Now, having said that, again, testes continue to be the source of the majority of the male hormone. And so, historically, the first data that showed benefit was actually by surgically removing the testes, which is what we call orchiectomy or bilateral orchiectomy. And then medications began hitting the market and were evaluated in the late ’80s and then 1990s, beginning with Lupron – which by the way, in the ’80s, it was an injection that the patient had to give themselves every day, which is remarkable. 

But even then, there is a personal preference by patients to go and take injections as opposed to go through surgery with orchiectomy. But still, I would say for some patients it may be an option until it ought to be discussed as an option. Then what we know is this, is because of the potential other sources for the male hormone, the concept of what we call combined androgen depravation was being evaluated. 

And again, this goes back to the ’80s when the first drug was flutamide and then bicalutamide, and there are other drugs that became. And they kind of added a sprinkle, I call it, to survival. But it wasn’t dramatic, huge differences in survival. And so, generally, while we used it, everybody believed in using it. Moving forward, the drugs like abiraterone, enzalutamide, apalutamide are the three hormonal drugs that have demonstrated conclusively really an advantage in terms of prolonging life when added to the Lupron. 

So, what I tell my patients is that, when it comes to hormone treatment there is really no way around it. You can delay it. Some people are exploring for some patients who don’t have a lot of cancer, maybe a couple of areas, maybe just do targeted radiation and then leave the person alone to buy them some treatment-free time. 

And, to me, this is where the discussion that has to happen with the patient. What is the objective? Is the objective to kind of be ahead of the game and maximally treat the cancer with the hope of prolonging life? Or is the objective to delay treatment? And I would tell you that, with these types of conversation, nine out of 10 or 9.5 out of 10 men opt for moving aggressively up front with management. So, that’s that. 

Now, the one thing I should point out, one of the trials that also was a landmark trial in this disease was the study CHAARTED, which was an intergroup clinical trial at the time it was designed, led by ECOG, and the PI was Dr. Chris Sweeney. I was part of the team that worked on the design also of the study. 

And that was a trial that looked at adding docetaxel to hormone therapy, versus hormone therapy alone, to try to see if it adds something. Historically, all the chemotherapies prior to that that were added to hormone treatment for patients with newly diagnosed metastatic disease had not delivered. And docetaxel did. 

However, one thing I should point out, based on that trial – and I don’t want to go into too much details for the sake of time – the patients that seemed to be benefiting were the patients that had more aggressive, more disease in their system. And so, liver metastases, lung metastases spread in the bone at different areas, not like few isolated areas in the spine or the pelvis, but much more than that. 

And so, for the patients who have what we call high-volume prostate cancer based on scans – and I’m happy to explain what that means if it’s needed – these are the patients that I would offer either the docetaxel plus hormone treatment, which is the injection, or the injection plus the hormonal pills that I mentioned earlier. 

Katherine:

What about targeted therapy? How is that used? 

Dr. Hussain:

Okay. So, let’s begin with the molecularly targeted therapy. So, as we speak right now, for patients who have newly diagnosed metastatic disease that we call hormone sensitive, molecularly targeted therapy is not standard of care. So, I would encourage patients who may qualify for clinical trial to be involved in those. The flipside is – we can talk about it – is that molecularly targeted therapies, specifically with PARP inhibitors have pretty much entered in the space of prostate cancer with a couple of drugs that were FDA-approved. 

The other way of targeted treatment, which would be what we refer to targeted radiation, this would be a different story. This is not systemic treatment. This is a local treatment. And what is done is basically if patients do not have a lot of cancer in their body based on scans, and only certain areas, and they are starting systemic therapy, they can certainly consult with a radiation oncologist to target radiation to areas that are visible on scan. So, if somebody has a couple of, let’s say, pelvic bone lesions, maybe a lymph node, and they are already starting systemic therapy, they can consult with a radiation oncologist focal radiation. And so, that would be the general scheme. 

Katherine:

Many patients are confused about the role of genetics and biomarker testing in prostate cancer care. 

For people who haven’t heard of some of these terms before, let’s go into the definitions. So, what is genomic or biomarker testing, first of all?  

Dr. Hussain: So, I think there’s one thing. Maybe I can explain because the wording can be confusing. So, there is the genetics, and there is the genomics. The genetics would be what we inherit from our families. So, this would be present in our body. The genomics testing would be to look for what the structure of the genes of the cancer itself, cancer cells itself. Now, that doesn’t mean that this was inherited. It’s just that this is a renegade, and it evolved. And that is what is going to show up. 

The reason these two are important, both of them have implications potentially for treatment or perhaps clinical trials. And again, with the PARP inhibitors, the BRCA-like genes will have implications for treatment sort of for resistance cancers. 

With regard to the genetics, the implications are for, again, inheritance of family and potential risk for blood relatives. Now, there are panels that are FDA-approved for the purpose of genetic testing. And the requirement or the indications right now, anybody who presents with metastatic disease or an aggressive disease and diagnosis, the recommendation is to proceed with the genetic testing, certainly counseling and testing, because there are some people who prefer not to be tested. And that’s something else. 

What I tell my patients is this, even if the testing is done and it was negative for inherited genes that might put the patient family at potential higher risk, the fact that a person has prostate cancer by default puts potential, adds risks to family, to blood relatives. 

And the risks aren’t just for the males with regard to prostate cancer, but certainly breast cancer, ovarian cancer, pancreatic cancer potentially, and things of that sort. So, this is where I think a patient needs to be discussing with their doctors. And certainly, there are many centers that have genetics counselor, and so that’s where I generally refer my patients to. I counsel them myself, and then refer them also for more discussions with genetics counselor. 

Katherine:

What exactly are genetic mutations? And how do they impact a treatment path? 

Dr. Hussain:

Well, I think, again, it’s the changes that happens in specific genes that may promote the aggressiveness of a cancer. And so, the BRCA gene is one of the oldest genes that have been identified in breast cancer. And essentially, the body regulates itself. 

And when cancer cells come up and they sort of – the body no longer sustains that regulation, the genetic regulation in those cancer cells. Those cancer cells will behave the way they want to. That means that they’re going to grow faster. That means they could be resistant to treatment and things like that. And so, that’s what we check for, these alterations. And there are certain medications that would allow – and again, in prostate cancer, it’s not a lot. It’s just, as I said, right now the only things that are proven is the PARP inhibitors. This is essentially to kinda gang over the cancer cell, preventing from allowing it to repair itself so it can continue to grow. 

Katherine:

Some patients may not know if they’ve received these important tests. So, for patients that aren’t all that sure, what key questions should they be asking their physician or their specialist? 

Dr. Hussain:

So, I would say when it comes to the genetics testing, I believe a patient has to consent. 

Because again, we live in the U.S., and this is a private matter for the patient. So, this generally has to be the case. Otherwise, depending on the institution, sometimes some tests will require for the overall testing for looking for any genetic alterations, general tumor alternation. Different centers have different things. But the patient should ask and say to their doctor, “Have my cancer genes been tested? Have my genes been tested? And if they have, what are the results?” Because we generally share with the patients once it’s been done. 

The other things I should point out, some of the good things that have happened recently. Up until recently, when it comes to the tumor genomic testing, tissue was required. Nowadays, the FDA has approved blood tests that several companies now run that can actually collect blood sample and basically test it for circulating tumor cell genes there. 

Now, no testing is 100 percent perfect. But in situations like patients with prostate cancer who may not have recent tissue or adequate tissue for testing, certainly doing the blood test to verify if there is anything reflective of the genes of the cancer, and that may allow for potential actionable-type treatments. Again, up until now, this is more going to apply for potential clinical trials or resistant metastatic disease. 

Katherine:

Are there other important factors to consider, like a patient’s age, that can help them access the best treatment for their prostate cancer? 

Dr. Hussain:

Yes. And I think that age is one factor. What I say and what I tell my fellows, age is to be respected, but used to discriminate in terms of management. 

 We all age. And certainly, the body reserve is not the same. And so, that’s why I would say that has to be respected. But it doesn’t mean that we cannot treat patients. 

And I’ll tell you, it’s interesting. There are times where you have – I have a gentleman who used to run seven miles a day. He was 87 years old. This was in my days when I used to be in Ann Arbor at University of Michigan. And the gentleman came to me, and he said, “Dr. Hussain, I don’t feel good.” And I said, “Sir, why? What has happened?” “I can’t run like I did before.” And I said, “You’re not running?” “No, I am running. I’m just not able to do seven miles a day. I can do only four miles a day.” I’m like, whoa, that’s about 100% more than I do. 

Now, again, I’m bringing this as an extreme example. But for some of the oral agents, like the Olaparib trial, there were men in there literally late-’80s, early-’90s that were included in the clinical trials. Same thing goes for several of the other trials. 

I do think that functionality is important. So, if somebody comes to you so sick they are in a wheelchair, you really have to be very careful. And again, I’m just using kind of extremes. And so, you have to be careful by what you are able to do. And any time the doctor thinks the odds are going to be more harm than good, this is really where absolutely a situation where the physician needs to be careful about it, and the patient needs to understand it also. At the end of the day, it’s a shared decision. 

Katherine:

Before we close, Dr. Hussain, how do you feel about the future or prostate cancer research, and what would you like patients to know? 

Dr. Hussain:

First, let me say that I would love for the patients to know that they are a partner, a most critical partner in the process.  

That we need to continue the research and investment in research. It is research that will end up curing cancer. Wishful thinking will not do it. And patient volunteering, which I think is remarkable across all cancers. The business I’m in, the way that drug discovery and evolution often happen because patients volunteered. And without testing these new treatments and combinations, we will not be able to get better results.  

And I will tell you that, when I started my training, the median survival for patients with resistant prostate cancer was on the magnitude of about nine months. Now it is three years-plus. Now, you could argue, well, that’s not huge. But that is a huge change because, again, we’re picking up the cancers much earlier. And the patients who had, as I mentioned, metastatic disease, again, the longevity then at the time I was in training, but even afterwards, was give and take in the three years. And now we’re talking six-plus years. 

And so, there’s been tremendous progress. And really partnership with the patients and their families and supportive others is very critical, and investment in research. So, yes, advocate constantly for more investment in research. 

Katherine:

All sounds very promising, Dr. Hussain. Thank you so much for taking the time to join us today.

Transcript:

Dr. Valente:                

So, there are a lot of reasons that a woman undergoes a mastectomy. The first one is choice. So, anytime somebody is diagnosed with breast cancer, they actually have the choice of whether or not they want to remove their whole breast. So, even if their cancer is small, they do have the option of removing the whole breast. If the cancer is smaller, they might have the option to save the breast, which is called a lumpectomy.

Sometimes cancer is found, and it’s a little bit more advanced where saving the breast is not an option. So, the cancer is larger than a lumpectomy would allow. And sometimes that’s what’s called the extent of disease. So, the amount of breast tissue that’s involved requires a majority of the portion of the breast to be removed.

So, just because a woman has breast cancer that’s made its way out of the breast, into the lymph nodes, or beyond – so, metastatic cancer – doesn’t necessarily mean that she needs a mastectomy. So, just because you’ve got metastatic cancer doesn’t necessarily mean that the breast needs to be completely removed.

So, I think that one of the biggest misconceptions is that the more aggressive somebody is with their surgery, the better their chances with survival.

And again, taking a step back and saying you can choose a more aggressive surgery, but a more aggressive surgery doesn’t necessarily mean it gets you out of chemotherapy or it gets you out of radiation therapy. Those things are recommended, independent of a woman’s choice for the type of surgery that she may or may not pick.

Katherine:

Welcome to Insist Breast Cancer, a program focused on empowering patients to take an active role and insist on better care. Today, we’ll discuss the latest advances in metastatic breast cancer, including the role of genetic testing and how this may affect treatment options. I’m Katherine Banwell, your host for today’s program, and joining me is Dr. Julie Gralow. Welcome, Dr. Gralow. Would you introduce yourself?

Dr. Gralow:   

Hi, thanks, Katherine. I’m Dr. Julie Gralow. I’m the Jill Bennett Endowed Professor of Breast Medical Oncology at the University of Washington, Fred Hutchinson Cancer Research Center, and the Seattle Cancer Care Alliance.

Katherine:    

Excellent, thank you. Before we begin the discussion, a reminder that this program is not a substitute for seeking medical advice. Please refer to your own healthcare team. Well, Dr. Gralow, let’s start by helping people understand how breast cancer is staged. Could we go through those stages?

Dr. Gralow:     

The staging of breast cancer has traditionally been by something we call anatomic staging, which has the tumor size, the number of local lymph nodes involved, and whether it has metastasized beyond the lymph nodes. So, that’s TNM – tumor, nodes, metastases. And so, that’s the classic staging, and based on combinations of those things, you can be a Stage 0 through Stage 4. Stage 0 is reserved for ductal carcinoma in situ, which is a noninvasive breast cancer that can’t generally spread beyond the breast, so that’s Stage 0, and then we go up for invasive cancer.

Interestingly, just a couple years ago, the big group that oversees the staging of cancers decided that in breast cancer, that TNM – the size, the lymph nodes, and the location beyond the lymph nodes – is not good enough anymore, so they came up with a proposal for what we call a clinical prognostic stage, which is a companion to the traditional TNM staging.

What they were getting at here was it’s not just how big your cancer is, how many lymph nodes, or whatever, it’s also at the biology of your cancer. So, this new clinical prognostic stage takes into account the estrogen and progesterone receptor of your cancer, the HER2 receptor at the grade, which is a degree of aggressiveness, and then, if your tumor qualifies, one of the newer genomic testing profiles that we use in earlier-stage breast cancer, such as the Oncotype DX 21-gene recurrence score or the MammaPrint 70-gene assay.

So, all of that goes into account now, and the whole point here is that the estrogen receptor, the HER2, the grade, and some of these genomics may actually make more difference than how many lymph nodes you have, where the cancer is, and how big it is, so it’s not just the size, but also the biology of the cancer that we’re trying to include in the new staging systems.

Katherine:    

In this program, Dr. Gralow, we ’re focusing on metastatic breast cancer. Would you explain when breast cancer is considered to have metastasized?

Dr. Gralow:  

That’s a great question because technically, if the lymph nodes in the armpit – the axillary area – are involved, that does represent spread beyond the breast, but if it stays in the local lymph node areas, it’s not technically called a metastatic or Stage 4 breast cancer. So, metastatic breast cancer would have traveled beyond the breast and those local lymph nodes, and some common sites would be to the bone, to the lungs, to the liver, less commonly – at least, up front – to the brain, and it could also travel to other lymph node groups beyond those just in the armpit and the local chest wall area as well.

Katherine:   

What about subtypes? How are they determined?

Dr. Gralow:   

The main way that we subtype breast cancer right now is based on the expression of estrogen and progesterone receptor, the two hormone receptors, and the HER2 receptor, the human epidermal growth factor receptor. So, to date, those are the most important features when we subtype, and so, a tumor can either express estrogen and progesterone receptor or not, and it can overexpress or amplify HER2 or not, and if you think that through, you can come up with four different major subtypes, in a way, based on estrogen receptor positive or negative and HER2 positive or negative.

When all three of those are negative, we call that triple negative breast cancer, and that’s about 18-20% of all breast cancers as diagnosed in the U.S. And then, when all three are positive, we sometimes call it triple positive, and the reason that we subtype is because we know that those different subsets act differently and that we have different drugs to treat them with, and we’ve got great drugs in the categories of hormone receptor positive and HER2 positive, and increasingly, some recently hope in a new drug approval or two in triple negative breast cancer as well.

Katherine:     

For a patient to get diagnosed, what are the essential tests?

Dr. Gralow:  

So, we’re talking about metastatic breast cancer here, and in the U.S., maybe up to 10% or slightly less of breast cancer is technically Stage 4 or metastatic at diagnosis. That means at the time we first found it in the breast, it had already spread beyond. So, an important thing that we’ll do with a newly diagnosed breast cancer is especially if there are a lot of lymph nodes are involved or the patient has symptoms that might say there’s something in the bone, liver, or lung is staging.

So, we’ll use scans – maybe a CAT scan, bone scan, or PET scan – and we will look at whether the disease has gone beyond the breast and the lymph nodes, and if so, where. So, maybe 8-10% of breast cancer diagnosed in the U.S. already has some evidence that it has spread beyond the breast, but the most common way that metastatic breast cancer happens is that a patient was diagnosed possibly years and years ago, treated in the early-stage setting, and now it comes back, and that is the most common presentation for metastatic breast cancer, and sometimes that can be due to symptoms.

As I said, if it comes back in the bone, maybe that’s bone pain. If it’s in the lung, it’s a cough. There are symptoms. Sometimes, it’s because we’ve done a blood test or something and we find some changes there.

And so, when a breast cancer has recurred, it’s really important to document that it’s really breast cancer coming back, first of all, and so, if we can, we generally want a biopsy, and we want to stick a needle in it if it’s safe to do, and look and verify that it looks like breast cancer, and also, it’s really important that we repeat all those receptors that we talked about from the beginning because it can change.

So, a cancer up front 10 years ago could have been positive for estrogen receptor, but the only cells that survived – mutated, changed – were estrogen receptor negative, so what comes back could be different. So, it’s really critical to get that biopsy, repeat the estrogen/progesterone receptor and HER2, and also, in an ideal world, now that it’s 2020 and we’re moving more toward genomics, to do a full genomic profile and look for other changes and mutations that could drive our therapeutic options.

So, staging, knowing where the cancer is, getting a good baseline by understanding where it is and how big it is so that we can follow it and hopefully see that it’s responding to treatment, and then, repeating all of the biology components so that we know what the best options are for treatment are really critical.

Katherine:  

Right. How can patients advocate for a precise breast cancer diagnosis, and why is that important?

Dr. Gralow:    

Well, all those things I just mentioned are key. Knowing exactly where it is so that we can monitor it – for example, if the cancer has come back in the bones, we would add what we call a bone modifying agent, a drug like zoledronic acid or denosumab – Zometa or – which can suppress bone destruction from the cancer, but if it’s not in the bone, we wouldn’t add that.

And, we want to have a good look everywhere so that we can see if it’s responding because sometimes, the tumor can respond differently in one area than another. Also, I think it’s really important to know what your treatment options are by doing that biopsy, getting a full panel, and looking at potentially hundreds of genes that could be mutated, deleted, or amplified so that we know what our treatment options are.

And, we’re not going to use all the treatment options up front, so it’s helpful for knowing that if this treatment doesn’t work or is too toxic, what are the second-line or third-line options? So, we make sure that there’s what we call good staging up front so we know where the cancer is, and then we make sure that we’ve looked at it as best we can in 2020 with all the genomics.

That would give us the best chance of being tailored – individualized – to the tumor. Sometimes, if we can’t biopsy it, like with a needle that would go into a liver spot, then increasingly, we’re looking at what we call liquid biopsies, and that can be drawing the blood and seeing if we can find parts of the tumor, whether it be the DNA or the RNA that’s floating around in the blood, and sometimes we can get that information out of the blood as well.

Katherine: 

All right. Dr. Gralow, when you meet with patients, what are some of the more common misconceptions that you hear related to diagnosis?

Dr. Gralow:  

Well, I think people do confuse – especially at an early diagnosis – that the metastases, the travel to the local lymph nodes, is not the same as a metastatic breast cancer, so we spend some time talking about how it’s still curable and not considered a distant metastasis if the lymph nodes are in the armpit or up above the collarbone, and so, that’s something that we spend some time talking about.

This whole term of “metastatic recurrence” – unfortunately, when you start looking online and get your information from Dr. Google, you read right away that it’s no longer curable, and in 2020, yes, that’s true. That’s probably the most specific statement that we can make. We are not going with curative intent, which means we treat for a defined amount of time, and then all the disease goes away, and we stop treatment, and then you go on with your life, and it never comes back. That would be cure.

But, I think it’s really important to point out that much of metastatic breast cancer can be highly treatable, and what we hope to do – and certainly, at least a subset of metastatic breast cancer – we want to convert it more to what we would call a chronic disease, and so, think of it more like hypertension, high blood pressure, or diabetes. These are diseases that we generally don’t cure with treatment, but that we can control with drug therapy, which sometimes has to be adjusted, and if we don’t control it, we can get some bad complications.

So, that’s not all metastatic breast cancer, unfortunately – we can’t convert all of it do something where we can use a therapy for a long time that keeps it in check and where you have a pretty good quality of life – but we’re hoping that more and more, we’re getting targeted therapies and more specific treatments to patients so that we can convert more patients to a more chronic kind of situation.

Katherine:

So, it’s something that patients live with.

Dr. Gralow:  

Right.

Katherine:  

Many people are confused about genetic testing. They often think that it relates to ancestry or physical traits like hair and eye color. What’s the role of genetic testing in breast cancer?

Dr. Gralow:    

Well, you can do genetic testing of the patient’s inheritance, which is how most people think of genetic testing, and that’s actually really important and increasingly important in metastatic breast cancer to do your own inheritance. Have you inherited a gene that was associated with how your cancer developed? Because now, we actually have a class of drugs called PARP inhibitors that are approved for tumors that have a BRCA1 or BRCA2 mutation with them. Most of those mutations were inherited, but not all. Sometimes they can develop as well.

So, now, when my patient – if she didn’t previously have genetic testing for an inherited risk for breast cancer either coming from mom or dad’s side of the family, a lot of people do have that up front, especially if they’re younger at diagnosis or they have a lot of family members with breast cancer. If she didn’t have that genetic testing done previously, at the time of the metastatic occurrence, I’m going to recommend that that be done because knowing if the cancer is associated with one of these DNA repair genes – BRCA1, BRCA2, some other genes – we have a new treatment option, which is an oral pill that actually is highly effective if the tumor has a mutation in one of these.

But, we can also – so, that’s genetic testing of the patient’s own DNA, but we can also do what we call genetic testing – or genomic testing, if you will – of the genes of the cancer. What were the changes in the DNA at the gene level that caused a normal breast cell over time to develop into a cancer cell that’s now growing without responding to our body’s checks and balances? So, what were those mutations, deletions, or amplifications in the tumor itself?

So, we’ve got the patient’s genetics, we’ve got the tumor’s genetics, and both of those come into play when we’re making our best treatment recommendations and trying to understand what the right approach is.

Katherine:       

How is testing administered?

Dr. Gralow: 

So, for our inherited testing, those gene changes can be found in every cell in the body, so we can do that from a simple blood test where we just look at the blood cells. We can actually do it with our sputum and with a cheek swab, even. You can get enough of the DNA from the inside of the mouth to do that.

For a tumor’s genetics, we need some of the tumor, so that’s either done with a biopsy into the metastatic site or, as I mentioned before, increasingly, we’re exploring the potential for a liquid biopsy – so, drawing some blood and then trying to find pieces of the tumor that are shed into the blood.

Katherine:      

What advances have there been in testing?

Dr. Gralow: 

Well, it used to be – just going back a couple of years ago – that we didn’t do a lot of this genetic testing or genomic profiling of the tumor because we didn’t have many – the term is an “actionable mutation.” So, if we found something, would we do something with it? Did we have a drug we could use to do it? But, more and more and more, even in breast cancer, we’re finding actionable mutations that would drive therapy.

For example, in estrogen receptor positive breast cancer, we have a new class of targeted therapies called PI 3-kinase inhibitors – a drug called alpelisib or Piqray was approved in the last couple of years in that category – and it only is effective in estrogen receptor positive breast cancer that has a mutation in the PI 3-kinase gene. So, that would be something we’re looking for in the tumor’s genes, and actually, we need to know that there’s a mutation to even get the drug approved for treatment because it doesn’t work if you don’t have that mutation.

Increasingly, we’re finding some changes that can happen in the estrogen receptor gene and the HER2 gene, interestingly, so that you can have estrogen receptor expressed on your tumor, but over time, that tumor might develop an estrogen receptor mutation so that it stops responding to certain drugs that target the estrogen receptor.

And so, that’s called an ESR1. That’s the name of the estrogen receptor gene – an ESR1 mutation – and that would tell me probably not going to respond as well to a drug in the class we call aromatase inhibitors, but might respond better to a drug in the class that we call the selective estrogen receptor degraders like fulvestrant or Faslodex, is the name of a drug in that class.

We’re also finding that you can have what we call activating mutations in HER2, and they can be present whether the tumor overexpresses HER2 or not, and we’ve got some ongoing clinical trials looking at if the tumor doesn’t have extra HER2 on its surface – so, it doesn’t have extra HER2 protein, but at the gene level, it’s got an activated HER2 gene – we can use certain types of HER2 therapy to treat it, and we’re testing that right now in clinical trials.

So, could we even use some HER2 drugs even though technically, the tumor would be classified as HER2 negative? So, fascinating increasing information that we’re understanding, and I also mentioned before we can inherit mutations in genes such as BRCA1 and 2, but fascinatingly, the tumor can acquire those mutations. Even if we didn’t inherit a mutation, we can see mutations in the BRCA1 and 2 gene – we call those somatic as opposed to germline mutations. So, “germline” means it’s in every cell in your body, but “somatic” means the tumor somehow acquired this over time.

And so, we’ve done – we just presented some very early results of a trial, and we’re expanding this trial, looking at if you didn’t inherit a BRCA1 or 2 mutation, so technically, you don’t qualify for a PARP inhibitor, but if the tumor acquired a mutation and we can prove that with testing the tumor’s DNA, then we have seen responses from these PARP inhibitors, so that opens up another whole class of treatments, and there are other DNA repair genes that actually may be qualified as well that we can inherit or that can be acquired by the tumor.

So, more and more, we’re doing this genomic profiling, and it is leading to results that would give us possible treatment options.

Katherine:  

Dr. Gralow, the goal of this program is to provide the confidence and tool for patients to advocate for the essential tests to get best care personalized to them. Are there specific tests that patients should make sure they have?

Dr. Gralow:  

Well, there are a lot of assays out there to do this genomic profiling or genetic testing of the tumor, so I don’t promote any one. Various institutions do it and do it well, various companies do it, but I think every metastatic patient should have the tumor looked at in this kind of profiling.

I also think every metastatic patient should advocate for having a biopsy of their cancer, and if a biopsy cannot be done safely in the recurrence, then see if they could get a liquid biopsy – have blood drawn to find it. So, I think that patients should be asking about this. Sometimes, insurance won’t always cover it, and so, my job as a treating physician is to advocate for that, to do an appeal.

More and more, because we have so many actionable mutations in breast cancer now, I’m not having insurance decline, but occasionally, it does, and then it’s our job as the healthcare providers to make the case that yes, this will impact the patient, and yes, it should be covered by insurance.

Katherine:  

You’ve been referring to a number of terms. Patients may have heard the BRCA or “braca” that relate to breast cancer in genetics. Would you give us an overview of common mutations in breast cancer?

Dr. Gralow:    

So, of the mutations that we can inherit, the first two that were discovered were BRCA1 and BRCA2, and for all breast cancer – not just metastatic, but all breast cancer – we think that maybe 5-10% of breast cancer is the direct result of the inheritance of a strong gene that gives you a high – not 100%, but a high likelihood of developing breast cancer.

So, for BRCA1 and 2, these two genes are associated predominantly with breast and ovarian cancer, and if you live out your normal lifespan, you could have up to a 75-80% chance of getting one of those two cancers, and breast cancer being more common. Also, some association with some other cancers including, interestingly, prostate cancer, which we’re learning more about.

So, BRCA1 and 2 are the most common, and they tend to be found – because they have such a high association with the risk of breast and ovarian cancer, they tend to be found in families that have a lot of other breast cancers, and also breast and ovarian cancer presenting at a younger age. So, you’ve inherited a gene that leads to a high predisposition, and the cancer occurs earlier.

So, whereas the average age of diagnosis of breast cancer in the U.S. is 61-62 most commonly, in a patient who’s inherited a BRCA1 or 2 gene mutation, it’s closer to 40-42 – so, a lot younger. And then, there are a variety of other genes that can be inherited that are either much less common or have a weaker link. So, for example, there are genes called CHEK2 or PALB2, ATM, P53 – I just mention that because some of the listeners will potentially have one of those mutations or have heard it. Those are either rarer or they’re associated with a weaker chance of getting cancer.

So, those might be more commonly found in a family that doesn’t have a lot of cancer in it because a carrier – the mother or the father – and their other relatives would have maybe only a 30% chance of getting breast cancer in some cases. So, there would be a lot of carriers who don’t get cancer.

So, as I mentioned earlier, I think it’s really important – especially right now in metastatic breast cancer – that pretty much everybody, even if you didn’t have a strong family history, even if you weren’t diagnosed at a young age, get tested because if we find one of these inherited mutations, we now have some additional treatment options, especially right now, approved for BRCA1 or 2, but clinical trials going on for many of these other genes.

Katherine: 

How do these mutations affect disease progression and prognosis?

Dr. Gralow:          

So, most of the genes I’ve mentioned – in their normal state, they’re critical, actually. They’re called DNA repair genes, and their job in our life is when we accidentally make a mistake when we’re replicating our DNA and two cells are dividing, if there’s a mistake in the DNA, they go in and repair it. And, we’ve got all kinds of mechanisms to try to prevent mutations from happening as cells divide, and BRCA1 and 2 are a key part of that, and so, they’re fixing it.

So, if you inherit a mutation in one of those genes, you still have some ability to repair any routine mistakes that are being made, but over time, you have less ability, and then, if you get a cancer that has a deficiency in BRCA1 or 2, those cancers can be more sensitive to certain kinds of chemotherapy that affects DNA repair.

So, for example a class of chemotherapy agents called the platinum drugs – carboplatin and cisplatin – may be more effective in BRCA1- or 2-mutated cancers, also more generally in triple negative breast cancer because they can be more similar to BRCA1-mutated cancers in a lot of ways.

So, to go back to your original question, once a cancer has developed in a patient who has a BRCA1 or 2 mutation, we treat that cancer for what it is. So, it might have developed estrogen – have estrogen receptor on the surface or HER2, so we treat it as the subtype that developed, and actually, the chance of cure is just the same for BRCA1-associated breast cancer as it would be for one that doesn’t have a BRCA.

But, the chance of getting a second breast cancer – a totally new breast cancer – would be higher unless you chose to remove both of your breasts and the bulk of your breast tissue. So, decisions like surgery – if you had a known BRCA1 mutation, we’d treat the cancer you have now aggressively and for cure, but when you talk about your surgery options, we’d say doing more aggressive surgery, like removing both of your breasts – that’s not gonna improve your chance of surviving the cancer you have now, but it will markedly reduce the chance of getting a second breast cancer.

So, you could consider that as an option for surgery – not to improve your chance of this cancer, but to reduce the chance of another breast cancer. So, your surgery decisions might be impacted by knowing your BRCA1 or 2 mutation. And then, clearly, if you had metastatic breast cancer, knowing if you had the option of a PARP inhibitor, one of the drugs in that class could be – you could have a different treatment option for drug therapy.

Katherine: 

Well, Dr. Gralow, what other factors should be taken into consideration with a treatment route?

Dr. Gralow:   

I always like to think of the treatment decision as relying on three factors, and the first relates to the tumor factor, the cancer factor.

So, we talked a lot about the biology, the estrogen receptor, the HER2, the genomic profiling. So, that’s critical, but there are two other components that we need to really strongly consider when trying to devise the right treatment regimen. One of those is patient factors, and not just the patient’s genetics, but are they pre- or post-menopausal?

What is the age? Where are they in life? Are they young with young kids? Are they working, and is that an important priority for them? Are they older and with grandchildren, and they don’t need to work? What is it that would be critical? What are the patient’s priorities here, and what are their fears, what are the things they would – what would be really important as we plan a regimen? And so, the patient factors which would be patient priorities and where they are in life right now.

And then, there’s factors related to the treatment itself, which would include not just how effective it is, but – and, this is really important when trying to decide regimens – what are the side effects of a regimen? For some patients, hair loss is a big deal, and we can put it off as long as possible – maybe choosing the first couple regimens don’t cause hair loss sometimes.

But, for other people, that doesn’t matter to them. For some, we have oral – some regimens, and that could keep them out of the infusion room, and others actually – I’ve had patients who actually like coming into the infusion room regularly so that they can review the side effects and get the reassurance provided by it. So, we’ve got different route of administration of the drugs, different side effects. If you already had, for example, a neuropathy – a numbness/tingling of fingers and toes – from treatment that you might have gotten for early-stage disease, we’d probably want to avoid drugs where that’s their major side effect in the metastatic setting and that would increase that even further.

We’ve got some drugs that cause a lot of toxicity to our GI system – nausea, vomiting, or diarrhea – and other drugs that don’t. And so, understanding what symptoms the patient already has and actually tailoring the treatment based on some of the side effects of the drug could also be done, as well as how they’re administered. So, again, patient factors, tumor factors, and then, factors related to the treatment itself all come into play when we make decisions.

Katherine:    

There have been so many advances in breast cancer research. What are you excited about in research right now?

Dr. Gralow: 

Well, every single drug that’s been approved, every single new regimen that’s been approved in breast cancer is the direct result of clinical trials, and this is a major part of my career, is to help patients get access to clinical trials and run important clinical trials that could lead to new discoveries – is this regimen better? What’s the toxicity?

Because until we have a cure for breast cancer, we need to do better, and we need to research better treatment options. So, doing trials, having access to clinical trials where you can participate, help move the science forward is key.

I think where we’re moving with breast cancer is the more we’re understanding the patient and the tumor, the more we’re realizing every single breast cancer is different, actually, and whereas when I started my training 20-plus years ago, breast cancer was breast cancer – we weren’t even using HER2 yet, we were just learning how to use estrogen receptor, and we kind of treated everything the same – now, we’re subsetting, and subsetting, and subsetting. Even in triple negative breast cancer now, which is about 18-20% of breast cancer, we’re subsetting.

Does that triple negative breast cancer have PD-L1, which is associated with being able to get immunotherapy drugs? Does it express androgen receptor? Because sometimes, even a breast cancer that doesn’t have estrogen or progesterone receptor can express the androgen receptor, like prostate cancer, and we can use some prostate cancer drugs. So, even triple negative breast cancer we’re subsetting and subsetting, and could that triple negative breast cancer be associated with a BRCA1 or 2 mutation, and then we can use the PARP inhibitors?

So, I’m actually really excited about that we’re learning more and more, and subsetting, and not treating breast cancer as one size fits all, and if we can better tailor the treatments to the patient and the tumor, that we are going to get to the point where I can tell my patients yes, we can get cures in metastatic breast cancer.

Katherine:    

For patients who may be hesitant to speak up – to advocate for themselves in the process – I’m gonna start again. For patients who may be hesitant to speak out for themselves and advocate for their own care and treatment, what advice do you have?

Dr. Gralow:   

You have a whole team who’s behind you, and I’m the MD on the team, but I’ve got a nurse practitioner, and a nurse, and a scheduler, and a social worker, and a nutritionist, and a physical therapy team, and financial counselors. I’ve got a whole team who works with me. And so, a patient might be hesitant to speak up during the actual appointment with their physician. It’s a short amount of time. I would recommend come into it with written-down questions because things go fast. You don’t get a lot of time with your doctor.

Things go fast, but don’t come in with 25 questions, either. Pick your top few that you want to get taken care of this visit because if you come in with 25 or 30, you’re gonna lose the answers to most of them. Maybe bring somebody with you who’s an advocate and a listener for you who could be taking notes, so you can process and you don’t have to write it down, or ask if you can record it. It’s really important if you’re newly diagnosed or maybe there’s a progression and you’re going on a new treatment. That’s okay too.

But, I would also say you have a whole team behind you, so sometimes, if you don’t have time or if you’re hesitant to speak up in your doctor’s visit, you can ask the nurse, or maybe you can ask the social worker for help, even. See if there’s support groups around.

Interestingly, we’ve got a peer-to-peer network where patients can request to talk to somebody else who’s matched to them by some tumor features, and their stage, and things like that. Maybe finding somebody else who’s gone through something similar, and somebody independent to talk to instead of relying on your family.

It can also be really helpful to talk to a therapist or a psychologist about your fears, and sometimes, you want to be strong for your family, strong for your children and all, but you need a safe space with somebody that you can just express your fears and your anger if that’s what’s going on, or your depression or anxiety to while you’re trying to hold a strong face for others in your family. So, I would encourage patients to look at who is the whole team and talk to the other members of the team as well, and sometimes, they can help advocate.

Also, find somebody who might be able to come to your appointments with you, somebody who will help you advocate or remind you – “Didn’t you want to ask this question?” – or be another set of ears that you can process it with afterwards.
