We have received some questions from audience members earlier on. And so, David writes, “My care team has suggested immunotherapy to treat my lung cancer. I’m optimistic about the results, but nervous about symptoms and side effects. What can I expect?”

Dr. Carbone:              

The immunotherapy is a potent therapy, but you have to understand, you’re dealing with lung cancer, which is a rapidly fatal disease when untreated. So, there’s a balance there. There’s a risk/benefit calculation that happens in picking any treatment.

And it turns out that I would say most lung cancer patients today have immunotherapy as part of their first treatment. Immunotherapy ramps up your own immune system to make it more effective at seeing the cancer, which has previously grown because it’s hidden itself behind a kind of invisibility cloak, and these immunotherapies remove this invisibility cloak so that the immune system can see it.

But at the same time, this process is a normal process that’s used to keep the immune system in check, and keep the immune system from attacking normal tissues, as well. So, it’s pretty common that we see people on immunotherapy have some kind of autoimmune side effect.

The most common side effect with immunotherapy is a skin rash, and usually it’s mild, and you just treat it with a topic corticosteroid, and it’s not a big issue. But it sometimes can be very severe. Like everything else, there’s a spectrum. I would say most patients have no skin problems; some have severe; and it’s almost always treatable. The next most common side effect is thyroid endocrine disorders. So, people will get thyroid function loss. And so, this is something that we follow carefully in the clinic, and people who are on immunotherapy.

And when we start seeing their thyroid levels going down, we just start them on thyroid medication, and that completely fixes that problem. So, but it’s usually permanent, and even after they stop immunotherapy, they’ll need to take thyroid medicines and adjust their thyroid levels.

And then, there’s a whole slew of other possible side effects that are less common. Some are very severe. Less than one percent of patients have a severe side effect called colitis, which causes diarrhea, which can even be life-threatening, but is also treatable if detected early. Very uncommon to be so severe, but patients should let their doctors know if they experience unusual diarrhea.

You can also have inflammation in your lungs called pneumonitis. So, if there’s an onset of shortness of breath, of course, you’ll tell your doctor, and that can be treated, as well. And anything else, there’s a huge list of other things. Arthritis, uveitis, other things that happen, but are pretty rare.

Katherine:                  

Hello, and welcome. I’m Katherine Banwell, your host for today’s program. Today, we’re going to discuss how you can insist on the best care for your non-small cell lung cancer.  

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. All right, let’s meet our guest today. Joining me is Dr. David Carbone. Dr. Carbone, welcome. Would you please introduce yourself?

Dr. Carbone:              

Thank you, Katherine. It’s a pleasure to be here. I’m David Carbone. I’m the director of the thoracic oncology center at Ohio State University in Columbus, Ohio. And I have a 35-year clinical and research interest in lung cancer, and I’m a medical oncologist myself.

Katherine:                  

Excellent, thank you. Thank you for joining us today. Before we get into our discussion, which will focus on non-small cell lung cancer, let’s talk about the types of lung cancer. What is the difference between non-small cell lung cancer and small cell lung cancer?

Dr. Carbone:              

Well, I like to tell patients every cancer is different from every other cancer, but they can be broadly categorized in two different categories, small cell and non-small cell.

And this derived from decades ago when small cell lung cancer just looked different under the microscope than non-small cell lung cancer. And different small cells can look different, and now we’re sub-typing small cells. But in general, small cells are treated pretty similarly. Non-small cells are divided into two main groups, the squamous cell carcinomas and the adenocarcinomas.

Adenocarcinomas have a variety of subtypes, as well, and then there are a few of the non-small cell lung cancers that are clearly non-small cell but don’t fit into either of those two categories, and they’re called large-cell or not otherwise specified.

And then, there’s a whole slew of rare types of lung cancers that we probably don’t have time to discuss, and mesothelioma that happened in the chest.

Katherine:                  

Right. Is one type of lung cancer more common than the other?

Dr. Carbone:              

So, the vast majority of lung cancers are the non-small cell lung cancers, about 85 percent. And among the non-small cell lung cancers, most of those are adenocarcinomas or non-squamous. Decades ago, squamous was the most common type, and in some parts of the world, it still is. But in the United States, it depends on the region; 60, 70 percent of lung cancers are adenocarcinomas.

Katherine:          

Right, okay, that makes sense. I’d like to pivot and talk about treatment for a couple of moments. What are the current approaches for treating non-small cell lung cancer?   

Dr. Carbone:          

Well, that’s a complex question. The basic modalities are surgery, which is really still what we prefer, if we can detect it early; radiation therapy; and medical therapy.

And medical therapy can be divided into chemotherapies of some sort – what we call targeted therapies, based on genetic abnormalities in the tumor – and then, immunotherapies to harness the immune system to fight cancer. Those are the three major kinds of therapies.

Katherine:                  

It seems like patients really do have a lot of options, which is a good thing for them. But how do you then decide which treatment is most appropriate for a given patient?

Dr. Carbone:              

Well, it’s not straightforward. When I started 35 years ago, it really wasn’t clear whether any treatment made any difference, and we actually did a large, randomized trial of doing nothing versus treating, and showed that we could improve survival by a month or two with the currently available treatments. Now, we have a huge toolbox of types of treatments and combinations of treatments. And it really requires a careful analysis of the characteristics of the tumor to pick the best therapy.

And specifically, for the adenocarcinomas, the most common type, we now do a detailed genetic analysis on all of the tumors, which can completely change the type of treatment people get and the prognosis, and result in being able to match a pill-type targeted therapy to a particular genetic abnormality with really high efficacy and low toxicity. And there are other markers we use for immunotherapy choices. It’s become quite complicated.

Katherine:                  

If we’re breaking it down to staging, let’s start with that. What are the stages?

Dr. Carbone:              

Right. So, lung cancer, like many cancers, is staged I, II, III, and  IV, and of course there’s now As, Bs, and Cs, and subcategories of those. But the basic distinction patients need to know has some utility.

So, the stage I lung cancers, in general, are small tumors that aren’t invading into anything, that haven’t spread anywhere to none of the lymph nodes, to no other structures; and they’re the tumors that we like to find. And they’re the ones whose optimal treatment is surgery, with a good cure rate.

Stage IIs, in general, are those lung cancers that are like stage I, except they involve the nearby lymph nodes in the lung that are called hilar lymph nodes, and those have also a high cure rate, but not quite as so high with surgery; and generally, are treated with surgery followed by chemotherapy, and now, immunotherapy.

Stage III is what we call locally advanced. It’s still only in the chest, but it invades some important structure or has multiple lymph nodes that are deep within the chest. And some of these are surgically resectable, but the majority of stage IIIs, I would say, are not surgically resectable, and are treated generally with chemoradiation, again followed by immunotherapy.

With the stage IV lung cancers, really, that is the lung cancer that’s spread outside the chest; typically, to bones, brain, or liver, or elsewhere in the body.

And that is typically not resectable; though again, there’s exceptions to each of these general rules, and you really need to have that multi-disciplinary evaluation of your cancers to determine the best therapy. But in general, stage IV lung cancers are not surgical candidates, not treated upfront as radiation candidates, and they’re generally treated with medical treatments that go throughout the body, and treat spots of cancer wherever they are.

Katherine:                  

How about when we look at general health and comorbidities? How do those influence the treatment choices that you would make?

Dr. Carbone:              

Every patient is different, like every cancer is different, and we have patients who are 20-year-olds and patients who are 90-year-olds; and patients who’ve taken care of themselves, and those that haven’t done so well taking care of themselves.

More than half of patients, even though they used to smoke, are ex-smokers. And so, they generally are in better condition, but we have to take into account frailty and presence or absence of diabetes, kidney disease, and all those other comorbidities, which are common in lung cancer, which has a median age of onset in the upper-60s, where people have these kinds of comorbidities.

We try not to use age alone as a factor, because there are many robust 90-year-olds, and there are many 50-year-olds on oxygen. So, we have to look at the complete picture to plan the best therapy.

Katherine:                  

Yeah. What about treatment side effects? How does that bear on what you decide to treat the non-small cell lung cancer?

Dr. Carbone:    

Well, unfortunately, we don’t cure most lung cancers. And so, our treatments are designed to prolong life and improve quality of life.

So, we’re very aware of the impact of our treatments on the quality of a patient’s life, and we’ve worked hard, over the years, to improve the risk-benefit ratio of our treatments, so to speak. And again, when I started, we didn’t have good nausea medicines, and people got desperately sick to have a six-week prolongation in survival, and that was really of questionable utility.

But now, even the chemotherapies that we give are generally super-well tolerated. The chemotherapies used in lung cancer are often – people will say, “I feel a little tired for a couple of days, but then, I’m fine,” and they’d often continue to work. Most, I would say, have no nausea; they have no significant side effects; and the immunotherapies, on average, people have very few side effects. They can hardly tell they’re getting the treatment, though sometimes the side effects can be significant.

Like everything I’m telling you, there’s always a spectrum.

Katherine:                  

Of course.

Dr. Carbone:              

And the targeted therapies: Again, most often, people have very mild side effects, with maybe a little skin rash or a slight loose stool, or something. But often, it’s insignificant compare to the magnitude of the benefit they get from these treatments.

Katherine:                  

Let’s talk about biomarker testing. What is it, first of all, and what are you looking for, exactly, when you receive the results?

Dr. Carbone:              

Well, you have to order the results, so you have to know what to order. And we already touched on it a little bit. The genetic analysis of a tumor has become central to picking a therapy. And when I say “genetic analysis,” that is what you’re referring to as one of the biomarker tests we use.

Unfortunately, it’s true that many patients have therapies started without waiting for the results of these biomarker tests, and that really can have a negative impact on their care, because the results of this testing can make the difference between chemotherapy or a pill. It’s a totally diametrically different therapy.

So, these genetic tests look for things that we call driver mutations, and these are alterations in the genes of your cancer that are not present in the rest of your body; they’re not passed down to your children, or need to get looked for in your brother or your sister, like some of the breast cancer mutations you may hear about.

These are mutations that are present in the tumor that act like light switches, and they turn the cancer on to grow like crazy.

And through scientific research, we’ve discovered many of these in lung cancer, where, if we can find the specific driver mutation, many of these have specific drugs that can turn that switch back off. And virtually 100 percent or very close to every patient where we can find that matching drug to their driver will have some tumor shrinkage.

And it’s quite remarkable, but we need to do that matching, because these new drugs only work in that subset of patients with that mutation, and that’s why it’s so important to do that matching. And now, we have eight or 10 of these types of mutations that need to be looked for.     

Katherine:                  

Where do clinical trials fit in, Dr. Carbone?

Dr. Carbone:              

Well, I like to say that clinical trials are tomorrow’s standard of care available today, and all of the new treatments that I’m talking about for lung cancer that have made this dramatic difference in survival and quality of life: They’ve all come because of basic science research, understanding how cancers grow, designing drugs, and using them in people in an intelligent way.

Historically, we used to just grind up tree bark or dig things up from the bottom of the sea, and test them in tissue culture to see if they killed cancer cells a little more than normal cells. But today, the treatments we have are based on science, and the success of these treatments is very high compared to what they were historically.

And the way we determine whether a treatment is effective is through something called a clinical trial, where generally the new treatment is compared to the standard treatment.

And if there is no standard treatment, we still do sometimes use placebo-controlled trials, but often that’s placebo plus some chemotherapy, versus the new drug plus that same chemotherapy.

So, it’s really not a placebo-only type situation. But the trials are designed to rigorously test whether the drug improves outcomes, and are an extremely important step in developing these new drugs and finding new things to help patients.

Katherine:                  

A lung cancer diagnosis often has a certain stigma associated with it, but the majority of that is not based in fact. So, I’d like to play a little game with you called Fact or Fiction. All right? All right, first one. Fact or fiction: Lung cancer is a disease of the older population.

Dr. Carbone:              

If you have lungs, you can get lung cancer. That’s it. I’ve seen 20-year-old lung cancer patients. So, I think it can happen to anybody, and unfortunately, things like the CT screening programs are limited to people over the age of 50, but I’ve had many patients in their 30s and 40s. So, if you have lungs, you can have lung cancer.

Katherine:                  

Okay. Next one, fact or fiction: Quality of life is greatly diminished after undergoing treatment for lung cancer.

Dr. Carbone:              

I completely – fiction. I actually tell people often their quality of life is dramatically improved after starting treatments, and that’s my goal.

And with the new treatments, that’s often true. People will tell me within a week that they feel so much better on the treatment than they did before. So, that’s our goal. Our goal is not to make you feel worse. Our goal is to make you feel better.

Katherine:                  

Of course. All right, last one. Fact or fiction: There are no effective treatments for advanced lung cancer.

Dr. Carbone:              

So, the average survival for lung cancer years ago was four to six months from the time of diagnosis to death. That’s bad. And now, we are seeing in these subsets of patients years and years of survival with simple even pill-type treatments or immunotherapies. And even with the immunotherapies, sometimes you get treatments for a year or two, and then we stop; and we have patients who are years later, off of all treatments for metastatic lung cancer, still with no evidence of disease.

So, that is definitely fiction. We have highly-effective treatments for lung cancer. But unfortunately, like everything else, and like I’ve said multiple times, it’s not true for everyone. Our treatments aren’t ideal. Sometimes for a particular patient we can’t find a matching treatment, the standard treatments don’t work, and nothing we can find makes a difference. But I would say you never know that until you try, and for the vast majority of patients, we can definitely give them prolonged, good-quality life. And so, I think that that’s definitely fiction.

Katherine:                  

Okay, thank you. We have received some questions from audience members earlier on.

And so, David writes, “My care team has suggested immunotherapy to treat my lung cancer. I’m optimistic about the results, but nervous about symptoms and side effects. What can I expect?”

Dr. Carbone:              

The immunotherapy is a potent therapy, but you have to understand, you’re dealing with lung cancer, which is a rapidly fatal disease when untreated. So, there’s a balance there. There’s a risk/benefit calculation that happens in picking any treatment.

And it turns out that I would say most lung cancer patients today have immunotherapy as part of their first treatment. Immunotherapy ramps up your own immune system to make it more effective at seeing the cancer, which has previously grown because it’s hidden itself behind a kind of invisibility cloak, and these immunotherapies remove this invisibility cloak so that the immune system can see it.

But at the same time, this process is a normal process that’s used to keep the immune system in check, and keep the immune system from attacking normal tissues, as well. So, it’s pretty common that we see people on immunotherapy have some kind of autoimmune side effect.

The most common side effect with immunotherapy is a skin rash, and usually it’s mild, and you just treat it with a topic corticosteroid, and it’s not a big issue. But it sometimes can be very severe. Like everything else, there’s a spectrum. I would say most patients have no skin problems; some have severe; and it’s almost always treatable. The next most common side effect is thyroid endocrine disorders. So, people will get thyroid function loss. And so, this is something that we follow carefully in the clinic, and people who are on immunotherapy.

And when we start seeing their thyroid levels going down, we just start them on thyroid medication, and that completely fixes that problem. So, but it’s usually permanent, and even after they stop immunotherapy, they’ll need to take thyroid medicines and adjust their thyroid levels.

And then, there’s a whole slew of other possible side effects that are less common. Some are very severe. Less than one percent of patients have a severe side effect called colitis, which causes diarrhea, which can even be life-threatening, but is also treatable if detected early. Very uncommon to be so severe, but patients should let their doctors know if they experience unusual diarrhea.

You can also have inflammation in your lungs called pneumonitis. So, if there’s an onset of shortness of breath, of course, you’ll tell your doctor, and that can be treated, as well. And anything else, there’s a huge list of other things. Arthritis, uveitis, other things that happen, but are pretty rare.

Katherine:                  

Lindsay sent in this question: “My doctor has talked about putting me on maintenance therapy following my treatment regimen. What is maintenance therapy for lung cancer?”

Dr. Carbone:              

So, many of our treatments have a maintenance phase, and I’m not sure which treatment she’s talking about. But even with chemotherapy, now, if people are on chemotherapy alone, will usually use a double chemotherapy to start, and then will drop one of the chemos after a few cycles, and then continue the other as a maintenance.

A more typical regimen today is a combination of two chemos and an immunotherapy. And generally, we’ll stop the more toxic chemotherapy after a few cycles and continue the less toxic chemotherapy plus the immunotherapy, usually for up to two years.

After chemo-radiation, you’d have a maintenance immunotherapy as well. So, maintenance therapy is just a lower-intensity therapy after your initial therapy, designed to keep the cancer from coming back.

Katherine:                  

Right. Okay. We have one other question, this one from Shelley: “Is lung cancer hereditary? I’m curious if my children should undergo genetic counseling, since I was diagnosed with lung cancer.”

Dr. Carbone:             

Well, that’s a simple, complicated question.                                   

So, in general, lung cancer is not hereditary. It’s not like familial breast cancer or ovarian cancer, or those kinds of cancers, or retinoblastoma. Most cases of lung cancer are caused by environmental exposure to cigarette-smoking or radon, and are not passed on to your kids genetically, though there is shared exposure, right?

There are some really rare genetic predispositions that we sometimes find on these biomarker panels.

But the vast, vast majority of lung cancers are not heritable, and you don’t need to worry about your kids, except to tell them not to smoke, and test for radon.

Katherine:                  

Patients can sometimes feel like they’re bothering their healthcare team with their comments and questions. Why is it important for patients to speak up, and become a partner in their own care?

Dr. Carbone:              

So, it’s a fact that when patients get the diagnosis of lung cancer, everything changes in their lives. They suddenly have a whole new vocabulary thrown at them. It’s like their doctor is speaking French to them. They have to trust their life to a person they’ve never met before, and a whole cadre of people coming in and talking to them and poking them and running through scanners.

It’s very difficult for someone whose biggest concern was what to make for dinner that night, and now has a diagnosis of lung cancer, to really comprehend what’s going on. And lung cancer is complicated, so I recommend that patients really try their best to have at least a basic understanding of what’s going on, where their cancer is. I always show the patient their scans.

“Your cancer is here; this is what it looks like; that’s why you’re having that pain over there, because you have this spot here. Your genetic testing shows this and this, and that’s why it’s important, and that’s why we’re using this drug to match this mutation.” And these are things patients will understand if doctors will explain it to them.

And similarly, the side effects. Lung cancer patients tend to be tough people. They’ll say, “It’s not so bad, I feel better; but the side effect is not so bad. I’m just not going to tell them.” And it even happens in clinic that they’ll tell me they feel fine, and then they’ll tell the nurse that they hurt in their left elbow. And I have to go back in and ask them some more questions on that.

So, it’s extremely important to feel comfortable in communicating with your doctor, asking questions; “Why am I getting this scan? Why are we using this treatment? Is this the best treatment? Are there clinical trials available? I have this new symptom, x, y, z,” because symptoms are often much easier to treat when you catch them early than when you catch them late.

And you don’t get a medal for being a tough guy in this situation. Tell your doctor if you have pain, and they can manage it. Tell them if you’re short of breath, and they can help you feel better. They can’t help you if you don’t tell them, and you are your own best advocate in this situation. Ask questions about the treatment, and why that’s the best one for you; and, as I said, about clinical trials.

Katherine:

Excellent. Thank you so much. It’s important for people to remember that.                   

And I just want to remind our audience that you can send in your questions to question@powerfulpatients.org, and we’ll get them answered, hopefully, on future programs.

So, Dr. Carbone, just to wrap things up, what are you excited about in lung cancer research right now, and what would you like to leave the audience with?

Dr. Carbone:              

Well, there’s a lot to be excited about in lung cancer right now. There’s new therapies being approved all the time. We have more new approvals in the last few years than in the last few decades put together. So, there’s a lot to be excited about.

But there’s still a lot of room for improvement, and there are a lot of patients who still suffer and die from lung cancer. So, my message to patients would be to make sure they get their biomarker testing before they start treatment. And it doesn’t mean to get the tests sent off and start on Joe Random treatment, until the test comes back. This means wait until the test comes back before starting treatment.

And then, I would recommend getting second opinions, if a patient is in a private practice without availability of clinical trials, to investigate if there might be new clinical trials available for them; again, before starting treatment, because sometimes even that first dose of standard chemo may make you ineligible for a trial. So, No. 1 is biomarkers.

Katherine:                  

All right. Thank you so much for joining us today.

Dr. Carbone:              

Well, you’re very welcome. Thank you for helping patients better understand how to deal with this disease.

Katherine:

Why should you ask your doctor about biomarker testing?

Biomarker testing, sometimes referred to as molecular testing or genetic testing, identifies specific gene mutations, proteins, chromosomal abnormalities, and/or other molecular changes that are unique to YOU and YOUR lung cancer.

The analysis is performed by testing the tumor tissue or by testing tumor DNA extracted from blood to identify unique characteristics of the cancer itself.

So why do the test results matter?

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

In some cases, biomarkers can indicate that a newer approach, such as targeted therapy or immunotherapy, may work better for you.

Common mutations associated with lung cancer include the EGFR, ALK, ROS1, BRAF, TP53 and KRAS genes, among others. In some cases, there are inhibitor therapies that target specific mutations. For example, if the EGFR mutation is detected, it may mean that an EGFR inhibitor, a type of targeted therapy, may work well for your type of lung cancer.

Another common biomarker associated with lung cancer is PD-L1. PD-L1 is a receptor expressed on the surface of tumor cells. The presence of PD-L1 indicates that a lung cancer patient may respond well to immunotherapy.

The 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.

Identification of biomarkers may also help you to find a clinical trial that may be appropriate for your particular cancer.

How can you insist on the best lung cancer care?

  • First, bring a friend or a loved one to your appointments to help you process and recall information.
  • Before you begin treatment, ensure you have had biomarker testing. Talk with your doctor about the results and how they may impact your care and treatment plan.
  • Finally, always speak up and ask questions. Remember, you have a voice in YOUR lung cancer care.

Katherine:

We have a question that we received from an audience member earlier. Jeff asks, “How do you know if your lung cancer treatment is working?”

Dr. Wakelee:

So, there are a lot of ways of knowing if treatment is helping. So, the one I rely on the most is, “Does the patient overall feel better?” That is difficult to say exactly how. Sometimes people are having breathing problems; they feel that that’s better. Sometimes their energy’s lower. They feel better. It can be vague. We also use scans. So, we tend to get scans, depending on the treatment we’re giving, every couple of months plus or minus, sometimes, every three months to help track what’s actually going on. But occasionally, there are discrepancies.

So, sometimes, the scan, is it better? Is it not better? Can’t really tell. And then, you’re always taking that, “How does the patient feel?” So, usually, if the scans are better, the patient feels better. It’s easy. Usually if the patient’s feeling worse and the scan looks worse, clear decision. Not a good one, but clearly, we need to do something different. But sometimes, you’re left, and especially this happens with the first scan because you get a scan, it takes a little while, you start the new treatment, then you get the next scan, how much of the changes happened before you started the new one and how much didn’t? So, these can be more challenging conversations, but generally if the patient’s feeling a little bit better, the scan’s unclear, we usually say, “You know, let’s give this treatment a little bit more time.” We also, I think your question was specifically around how do we tell if it’s working, but you also often need to be thinking about, “Well, what’s it doing that’s negative to the person and is that potential, those side effects worth the benefits we are or are not seeing?”

So, it’s kind of all of those things together. It can be a bit complex.

Katherine:

What goes into the decision to change therapies if it becomes necessary?

Dr. Wakelee:

So, when we’re thinking about making a change, the way I always look at it is, is where we are today still okay or not? And, if it’s not, that would be because clearly the cancer’s growing or clearly the side effects are just not tolerable. Then, we decide together with the patient we need to do something different. And, when we think about what do we do next, we look at what have we’ve already done, did it work or not, if not, let’s do something more different. And so, let’s think about something that might be somewhat similar. When we’re dealing with targeted therapies, we have ways to try to figure out what changed in the tumor that made it now resistant or not working with that treatment.

And so, with some of the pill drugs, there’s been a lot of research and understanding how does the tumor change that helps it evade, get away from, be resistant to whatever treatment you’re on.

And then, sometimes, we have other pill drugs that work in that particular setting, not always. With immune therapy, we’re trying to better understand why does the immune therapy stop working?

Sometimes you can add back to it, like, you can add chemotherapy back to immune therapy alone or sometimes you can do radiation with immune therapy to get that response back. Or, add other combinations to it. So, that’s another thing that we’re working on. And then, like I said, if someone hasn’t ever had chemotherapy and the tumor’s become resistant, we’re going to be thinking a lot about chemo because that can play a role against so many different reasons that the cancer might not be responding to whatever treatments someone’s on. And then also, looking at how the patient’s feeling and doing, what their overall what we call “performance status, ” their sort of overall health, and how well do we feel with them that they’re going to be able to tolerate the next treatment because, you’re always having to weigh how much is this likely to help, and how might this harm in finding the right balance.

Katherine:

Let’s turn to treatment, Dr. Wakelee. On a basic level, what are the goals of treatment for lung cancer?

Dr. Wakelee:

So, with lung cancer, we’d love to cure everybody, that’s the ultimate goal, and do it in a way where people are able to continue living their life as they were before the cancer diagnosis. The ways that we do it, first of all, we’ve got to find the cancer, and that’s where screening is such an important aspect of things. If we can find the cancer at an earlier stage, we’re more likely to be able to cure someone.

So, what do I mean by “earlier stage?” Well, when a tumor first develops, usually, there is a single cell that develops a mutation, meaning a change in the gene, which gives that cell an advantage so it doesn’t die the way it’s supposed to. And then, it keeps growing, and dividing, and making new cells. And those over time get to a large enough size that they are the cancer. And given more time, those cancer cells start to spread into other parts of the body, usually first into what we call the lymph nodes, and from there then into other organs in the body. And this stage refers to health or how the cancer spread. So, the stage I cancer is still in that ball of cancer. Stage II means that it’s spread into some lymph nodes. Stage III is it spread into more lymph nodes, usually in the center part of the chest or mediastinum, and that’s where it starts to be much more difficult for the surgeons to be able to truly remove all of the cancer.

And then stage IV means that the cancer is not something that we’re going to be able to remove with surgery. It’s spread either within the lung to the lining of the lung or it has spread to other organs in the body. And so, when we talk about those stages that I, II, III, IV, it’s a bit more complicated than that. But, I think for most people, if they just think about it as stage I, just the cancer, stage II, lymph nodes and the lungs, stage III, lymph nodes in the center, and then stage IV, elsewhere, that’s a good way to kind of wrap your head around it.

And when we talk about stage I and II, that’s the truly early stage where we hope to be able to cure people with surgery. Surgery alone is enough for the majority of people with stage I cancer, and for maybe half, a little more than half of people with stage II. So, how can we be better than that? Well, that’s where there’s been a lot of new advances. So, adding chemotherapy after surgery can help a lot of stage II patients.

If the tumor genomic testing biomarkers shows that there’s a mutation called EGFR, we now know that there’s a pill drug that people can take that would prolong the time to when the cancer might come back. And then, just very recently, there was stated that that immune therapy drugs

IV can also prolong time to when the cancer comes back and maybe improve cure if the tumor has that biomarker called PD-L1. So, that’s that early stage. So it’s, again, getting more and more complicated and emphasizing that you’ve got to understand the biomarkers of the tumor to know how to best help someone.

When we move to stage III, some have surgery, but when you can’t have surgery, then we do the chemotherapy and the radiation. That’s the key part of the treatment there. And, we also know that immune therapy can be really helpful for a lot of patients when it’s given after the chemo and radiation’s completed. And then for stage IV, I talked about that already, which is you’ve gotta do the biomarkers to figure out the best treatments for some people starting with a targeted pill drug is the right thing if their tumor has those right gene mutations.

For other people, immune therapy alone might be an option if the PD-L1 level is very high and they don’t have one of those gene mutations in the tumor. And for a lot of people, chemotherapy or chemotherapy plus immunotherapy is the right strategy.

Katherine:

Would you help the audience understand the types of therapy for small cell lung cancer specifically?

Dr. Wakelee:

Yes. So, small cell still has the same kind of staging, but it’s a little bit more simple. We talk about extensive stage or limited stage. And what that has to do with is we rarely do surgery for small cell. It tends to have spread earlier. There are a few cases where that’s done, but normally, we divide it up into limited or extensive. And when we talk about that, limited is the radiation doctors can get all of the cancer in one radiation field, and then radiation plus chemotherapy is the standard approach to try to cure. If it’s more extensive than that, then it becomes extensive stage.

And, the best treatment are going to be chemotherapy plus those immune therapy drugs added together.

And so, the chemotherapy drugs that we use for non-small cell and small cell, the platinum drugs play a role in all of it. The drug we partner is a little bit different. There’s a drug etoposide we use a lot in small cell and a lot of other options for non-small cell. And then, the immune therapy drugs, there are a lot of options that are fairly similar for both small cell and for non-small cell.

Katherine:

Dr. Wakelee, but what is genomic or biomarker testing?

Dr. Wakelee:

So, we are struggling with how to have one unifying way of describing it because it’s so complicated. So, to me, biomarker testing is any aspect of the tumor that helps us choose the best treatment for that patient. And so, it’s a very broad term. And, within biomarker testing, there are several different ways that we look at it.

So, one is to look at what proteins are on the cell’s surface. And, we do that by having stains that we use to stain the tissue. So again, complicated, but when a piece of tissue is taken out of the person, part of the tumor is removed. It’s sliced into little tiny slices, which are then put on glass slides that can be looked at under the microscope. And, that’s how the pathology doctors can look and see, “Ah, this looks like cancer,” or, “It doesn’t look like cancer.” When it does look like cancer, you can then put on stains, so basically, different colored antibodies that will light up if that particular protein is there. And so, that helps us figure out for sure that this started in the lung because there are specific proteins that are only found in lung. So, that’s one way we used it, and this is an older technology. But we also can use that to look for how much of this PD-L1 protein is expressed.

And so, that’s an important biomarker, but it’s not based on genomics, which is when we’re talking about the DNA.

Then, we have the genomic testing, and that’s when we’re looking at the genome of the tumor and how that genome is different. And, that’s that DNA or RNA testing. We talk about it with the next-gen sequencing. So, “sequencing,” any of those terms are all meaning we’re looking at some aspect of what makes the tumor genes and therefore the proteins made by the tumor different than the rest of the genes in the person.

And so, that testing, that genomic testing can be done on either the tumor specimen or that’s where we can do blood tests that will be able to pull out those bits of the DNA that are from the tumor versus from the person and help us figure out what’s going on with the cancer. So, when we talk about biomarkers, the whole picture, and when I’m talking with patients who are diagnosed with lung cancer, we talk about well, there’s chemotherapy treatment, which is good for almost everybody. There is targeted therapy.

Targeted therapy is usually based on those genomic tests, and the genomic tests can be done either on the tissue or on blood. But, they’re really important to have a full understanding of the

tumors to do a comprehensive or next-gen sequencing analysis of the tumor or DNA. And then, you have the immune therapy where that PD-L1 biomarker is important. So, that’s the way I think about it, and the biomarkers are really critical for helping us figure out what’s the best path forward for any individual patient.

When I started treating lung cancer patients 20 years ago, we only had chemotherapy. And now, for metastatic disease, with using the right biomarkers, we can figure out so much more about the cancer to be able to personalize the treatment, for many patients, being able to offer pill therapies that are somewhat less toxic and highly active and give people more time. And now, we’re in the immune therapy revolution, which is helping a whole other group of patients living with lung cancer to be able to live with quality life for much longer. And the pace of discovery is just going up so quickly. And, I think that’s what I’m most hopeful about is just how much attention is being paid on lung cancer and finding better therapies that are going to help more people for a longer period of time.

Katherine:

Can you provide an overview of important tests following a lung cancer diagnosis?

Dr. Wakelee:

That’s a fabulous question. When we think about the tests that we need to have done, they’re mostly tests that are done on the tumor, so, either if someone has a surgery or at the time of biopsy. and, that’s where we can figure out what we call, again, the histology that’s squamous or non-squamous. That’s when they look at it under the microscope. But, they also, with the tumor specimen, you can pull the DNA out of the tumor and then test for the gene mutations in the tumor. And, I always emphasize these are not changes in the genes that are in the whole person. They are things that are unique to the tumor. They are what make the tumor different from the rest of the person.

So, we look at those gene mutations, or that’s kind of a biomarker. So, there are a lot of terms that we use, and I know it gets really confusing. So, I try to use “biomarker” to mean all of these things, but that gene mutation is what we look at in the tumor tissue to see if there are specific changes that will allow us to give a pill therapy, a targeted pill therapy. And then, there are also aspects of the tumor that help us figure out whether or not the immune therapy might work, and most commonly, that’s something called PD-L1. That’s a protein that we look at on the surface of the tumor, and so again, under the microscope.

Katherine:

And, when you talk about extracting DNA, is that via a blood test?

Dr. Wakelee:

So, we have two different ways to do that. So, what I was talking about before was from the tumor tissue, you can extract the DNA. But now, there are these liquid biopsies where we can draw blood and find the tumor DNA that is different from the rest of the person’s DNA and look for those gene mutations in the tumor.

And that is where there’s a lot of developments happening. And, that’s so fabulous because they’re often faster results for patients, and it means that you cannot have to go through another biopsy. We still need the biopsy to establish whether or not there is even cancer. But, once we know that there’s cancer for sure, then we can use the liquid biopsies to get a faster information result on those gene mutations and to follow over time to see how the tumor evolves because tumors change after they’ve been treated.

Katherine:

Do you use imaging at all?

Dr. Wakelee:

Yes. Always. So, when someone is first diagnosed with cancer, we usually find that because of imaging, so, a CT scan or an X-ray, maybe they had a screening CT scan or maybe they had a cough that led someone to go get an X-ray, an examination. So, the imaging is a part of the original diagnosis. And in addition to CT scans, we’ll often get a PET scan that helps us look for, in a different way, the rest of the body, maybe an MRI of the brain to look in that area.

And then, wherever we’ve found the tumor, we will track that area with scans over time. And, it gets a little complicated for a patient that was found with what we call early-stage disease. So, stage I or II. Many of the times, those patients can have surgery and then we don’t have any tumor we can follow anymore. But we get CT scans to look to see if it could have come back. For patients with more advanced disease, so, stage III that couldn’t have surgery or stage IV, there we have areas that we’re going to continue to follow with the scans. And which scans and how often is going to depend a lot on what treatment the patient’s on and where the tumors are located that we’re tracking.

Katherine:

Do these tests differ for small cell lung cancer and non-small cell lung cancer patients? And, I know that non-small cell lung cancer is also known as NSCLC.

Dr. Wakelee:

Yes. So, long ago, the only distinction we had with lung cancer was that small cell versus non-small cell, and that is something that is seen under the microscope when that tissue is taken out from the biopsy. The pathology doctors look at it under the microscope, and the cells look different. And, the small cell lung cancer, those cells are small. It’s not very creative naming. And then, everything else is non-small cell or NSCLC. So, it’s SCLC and NSCLC. So, that was one of the first distinctions.

And, it is still very important because the chemotherapy drugs that we use are slightly different. And, the genetic, those gene mutations, we see them in any cancer. That’s what makes a cancer different from the rest of the body. But in small cell lung cancer, the tumor mutations that we see are not things that we know how to target specifically. In non-small cell, there are targets that we can target specifically for some patients.

So, just there, it’s different in having the targeted pill drugs in non-small cell, not so much in small cell. With immune therapy, those newer immune therapy IV drugs, they can work in both small cell and non-small cell.

But for small cell, the biomarkers, that PD-L1 level is not as important for helping us figure out who’s going to benefit. For non-small cell, with many of the drugs, it is important. So, there are differences there.

Katherine:

We’ve been hearing the term “personalized medicine” a lot more often. How would you define that term?

Dr. Wakelee:

That’s a great question. So, I think back when I first started taking care of patients living with lung cancer 20 years ago, we really just had chemotherapy for those with metastatic disease. And for those with earlier stage disease, it was just surgery radiation. And since that time, we’ve learned a whole lot and brought in a lot of different types of treatment. Surgery and radiation still have important roles for many patients.

And we think about them as being targeted and personalized based on stage, but it’s a little bit different. When we talk about personalized, we’re thinking more about what are aspects about the tumor that allow us to pick the right systemic treatment. So, “systemic” meaning a pill or something that we give IV.

With chemotherapy, we don’t have much to pick between them as far as specifics for the tumor. We can look at what we call the histology, which is how it looks under the microscope, whether it’s the squamous type or the non-squamous type and some of the chemotherapy drugs matter there. But, in the last 15, 20 years, we’ve learned about the specific what we call “gene mutations” that define the tumor.

And, depending on the gene mutation in the tumor, for some patients, we can give them pill therapy drugs that will work well. So, that’s personalized. Or, immune therapy now is an option for a lot of patients. That’s usually IV therapy.

And, there are some aspects of the tumor that can help us pick that also.

Katherine:                  

Excellent. Thank you. Before we get into an in-depth discussion on lung cancer treatment, we’ve been hearing the term “personalized medicine” a lot more often. How would you define that term?

So, that’s the way I think about it, and the biomarkers are really critical for helping us figure out what’s the best path forward for any individual patient.

Katherine:                  

Let’s turn to treatment, Dr. Wakelee. On a basic level, what are the goals of treatment for lung cancer?

Dr. Wakelee:              

So, with lung cancer, we’d love to cure everybody, that’s the ultimate goal, and do it in a way where people are able to continue living their life as they were before the cancer diagnosis. The ways that we do it, first of all, we’ve got to find the cancer, and that’s where screening is such an important aspect of things. If we can find the cancer at an earlier stage, we’re more likely to be able to cure someone.

So, what do I mean by “earlier stage?” Well, when a tumor first develops, usually, there is a single cell that develops a mutation, meaning a change in the gene, which gives that cell an advantage so it doesn’t die the way it’s supposed to. And then, it keeps growing, and dividing, and making new cells. And those over time get to a large enough size that they are the cancer. And given more time, those cancer cells start to spread into other parts of the body, usually first into what we call the lymph nodes, and from there then into other organs in the body. And this stage refers to health or how the cancer spread. So, the stage I cancer is still in that ball of cancer. Stage II means that it’s spread into some lymph nodes. Stage III is it spread into more lymph nodes, usually in the center part of the chest or mediastinum, and that’s where it starts to be much more difficult for the surgeons to be able to truly remove all of the cancer.

And then stage IV means that the cancer is not something that we’re going to be able to remove with surgery. It’s spread either within the lung to the lining of the lung or it has spread to other organs in the body. And so, when we talk about those stages that I, II, III, IV, it’s a bit more complicated than that. But, I think for most people, if they just think about it as stage I, just the cancer, stage II, lymph nodes and the lungs, stage III, lymph nodes in the center, and then stage IV, elsewhere, that’s a good way to kind of wrap your head around it.

And when we talk about stage I and II, that’s the truly early stage where we hope to be able to cure people with surgery. Surgery alone is enough for the majority of people with stage I cancer, and for maybe half, a little more than half of people with stage II. So, how can we be better than that? Well, that’s where there’s been a lot of new advances. So, adding chemotherapy after surgery can help a lot of stage II patients.

If the tumor genomic testing biomarkers shows that there’s a mutation called EGFR, we now know that there’s a pill drug that people can take that would prolong the time to when the cancer might come back. And then, just very recently, there was stated that that immune therapy drugs IV can also prolong time to when the cancer comes back and maybe improve cure if the tumor has that biomarker called PD-L1. So, that’s that early stage. So it’s, again, getting more and more complicated and emphasizing that you’ve got to understand the biomarkers of the tumor to know how to best help someone.

When we move to stage III, some have surgery, but when you can’t have surgery, then we do the chemotherapy and the radiation. That’s the key part of the treatment there. And, we also know that immune therapy can be really helpful for a lot of patients when it’s given after the chemo and radiation’s completed. And then for stage IV, I talked about that already, which is you’ve got to do the biomarkers to figure out the best treatments for some people starting with a targeted pill drug is the right thing if their tumor has those right gene mutations.

For other people, immune therapy alone might be an option if the PD-L1 level is very high and they don’t have one of those gene mutations in the tumor. And for a lot of people, chemotherapy or chemotherapy plus immunotherapy is the right strategy.

Katherine:                  

Would you help the audience understand the types of therapy for small cell lung cancer specifically?

Dr. Wakelee:              

Yes. So, small cell still has the same kind of staging, but it’s a little bit more simple. We talk about extensive stage or limited stage. And what that has to do with is we rarely do surgery for small cell. It tends to have spread earlier. There are a few cases where that’s done, but normally, we divide it up into limited or extensive. And when we talk about that, limited is the radiation doctors can get all of the cancer in one radiation field, and then radiation plus chemotherapy is the standard approach to try to cure. If it’s more extensive than that, then it becomes extensive stage.

And, the best treatment are going to be chemotherapy plus those immune therapy drugs added together.

And so, the chemotherapy drugs that we use for non-small cell and small cell, the platinum drugs play a role in all of it. The drug we partner is a little bit different. There’s a drug etoposide we use a lot in small cell and a lot of other options for non-small cell. And then, the immune therapy drugs, there are a lot of options that are fairly similar for both small cell and for non-small cell. 

Katherine:                  

Dr. Wakelee, you mentioned targeted therapies. How do they work?

Dr. Wakelee:               

Targeted therapies are something we can use when we find a specific gene mutation in the tumor. So, I mentioned before that in order for a cancer cell to become cancer, something has to happen to the DNA in the cell.

And, there’s a change or a mutation in the DNA of the cell which leads it to be a cancer. And, a lot of the time, that mutation happens in a specific kind of gene that makes a type of protein called a tyrosine kinase. And for those of you who haven’t studied a lot of science, it’s a word you might not have heard before. But basically, these tyrosine kinases are proteins in the body that make a lot of changes to what’s going on in the rest of the cell. So, they’re sort of what we call regulators. And, one way of thinking about them is like on and off switches. So, normally, their job is to sit and if the right molecule comes around, that turns it on, and then it turns on other proteins in the cell. And if that molecule isn’t there, it’s turned off. So, it’s this on and off switch that does a lot of other aspects of what’s going on in the cell. But, sometimes, a mutation happens. It turns it on all the time. So, it’s like if you leave the light on.

It’s on all the time, that’s using a lot of energy, and that’s actually what’s driving the cell to act like a cancer. And so, we can now look for some of those mutations that turn some of these tyrosine kinases on all the time. But, we’ve also developed drugs that we can use to turn them off. So, if we find this specific gene mutation that’s turning, say, the EGFR protein on all the time, if we find that, we can have the patient take a pill that then turns that off.

And that helps the cancer slow down, some of it die, some of the cancer cells die, but it doesn’t completely wipe it out. It helps the patient for a long time though by shrinking the cancer, helping them feel better because the symptoms are gone, keeping the cancer from growing. But, cancer cells are clever. They continue to divide, they can continue to make new mutations, and eventually, they figure out ways around that. So, when we talk about targeted therapy, it’s a setting where we find the cancer.

In the cancer, we find the gene mutation, it’s in one of these specific types of proteins, genes that make specific protein that turn something on that we can then turn off, and with those pill drugs, we can have a big impact for people.

Katherine:                  

And, what exactly is immunotherapy?

Dr. Wakelee:              

Immunotherapies are treatments that were used to help keep the immune system more active.

So, the immune system is a very complex mechanism. There are cells that their whole job is to figure out and find things that are not us. So, they are looking for bacteria, they’re looking for cells that have a virus in them, and when they find it, they attack. And, that attack can be in the form of antibodies, it can be cells that actually go in and attack other cells directly, and we are all familiar a little bit with the immune system because we know that if we get a cold, our body, we can get a fever, that’s part of our immune response, and we get better. And then, some people know the bad side of the immune system if they have allergies or certain autoimmune diseases where the immune system gets a little bit too revved up and starts to recognize normal things as foreign.

So, in the setting of cancer, normally, the immune system is able to recognize a cancer cell, see that it’s different from the rest, and get rid of it. But, cancer cells are clever and they figure out ways to evade the immune system. And, one of the ways they do this is they put a protein called PD-L1. So, PD-L1 is a protein that a lot of our normal cells use to say, “Just a normal cell. Ignore me.” And so, when an immune cell comes in and sees that, it gets turned off it goes away. So, what our immune therapies do is most of them are blocking that PD-L1 protein. And, when they do that, it’s sort of like taking away the stop sign. So, you’ve got a tumor using a stop sign to say, “Go away, immune cell,” you block it so the immune cells can’t see that stop sign, and so then it kills the cancer cell better. So, that’s how these drugs work, and that’s the immune therapy.

There are some other stop signs besides PD-1 and PD-L1, but that’s the most common. So, when we’re talking about immune therapy, it’s drugs that block that. So, they increase the ability for the immune cell to recognize cancers. The risk from them is that you can get the body to recognize normal tissue as a problem sometimes. So, that’s the toxicity that we watch for.

Katherine:                  

Right. What are the advantages of these new treatment approaches compared to standard chemotherapy?

Dr. Wakelee:              

Well, I think the most exciting news that we’ve seen in lung cancer over the last few years is that we’re actually helping more people live longer. And the way that we’re doing that is through these newer treatments. So, when we can personalize treatment by recognizing that a person’s cancer has a specific gene mutation and we can give them the right targeted pill drug, we can help them live longer and feel better because those often have fewer side effects. Wish I could say they were curing the disease, but they’re helping people live longer.

And, that can be measured in years for some folks, which is fantastic. And then, with immune therapy, again, they’re not working for everybody, but they were for a large number of patients with lung cancer with non-small cell to help them live longer with their cancer controlled. And so, we’ve actually improved the overall survival rates for lung cancer with these new developments. Where we can make even more of an impact is also by finding more of the cancers earlier, and that’s where cancer screening is so important also. So, by having more choices, chemotherapy can still help a lot of people. Targeted therapies can help probably close to 20, 30, 40 percent of people with non-small cell lung cancer that’s the adenocarcinoma type. And then, the immune therapies can help other people living with lung cancer. Usually immune therapies don’t work on the same tumors the way the targeted pills work. So, you’re kind of getting at different groups of people with those different strategies. It’s not completely true, but it’s a kind of general principle about it.

Katherine:                  

What about side effects for some of these treatment choices?

Dr. Wakelee:               

So, chemotherapy is one people fear the most, but I think it has a bit more of a bad reputation than it needs. A lot of the lung cancer therapies that are chemotherapy can be reasonably tolerated. I mean, I’m not signing up to go get chemotherapy just because. There definitely are side effects. The biggest one is people get fatigue, get really tired. Though, if they’re feeling horrible because of the cancer, a lot of times people feel dramatically better. But, tiredness, it can impact appetite a little bit, though cancer does that also. There can be nausea, vomiting, but we’re much better at controlling that with the newer drugs. Some cancer therapies cause hair loss, but a lot of our non-small cell lung cancer therapies don’t cause hair loss. So, there are a lot of options there you can talk about with your doctor. And then, when the blood counts are low, there can be risk for infection, low red blood cells with anemia.

So, there are a lot of different things. But in general, chemotherapy is better tolerated than people think it’s going to be because in the movies, they make it look horrendous.

With the pill therapies, again, lots of variability depending on the specific pill. Some of them cause rash. Some don’t. Some of them can cause some changes to the heart that we have to monitor with EKGs, electrocardiograms, some don’t. Some cause some changes to labs like for liver tests that we have to monitor. Some don’t. Some cause hair color changes. Some don’t. It’s always to gray, unfortunately.

So, there are a lot of different variations in what different treatments can do. And so, it’s just really important if your doctor is talking with you about starting one of the targeted pill drugs that you really ask what are the side effects I need to be watching for, what are the ones I need to know to call you about, and which are the ones I just know, “Okay, this is happening and it’s okay. It’s going to cause swelling in the ankles,” no, just a huge range of them. And then, with the immune therapy drugs, they tend to be mostly fatigue, just like with chemotherapy, though some people feel fine.

What we have to watch for is that they can cause what we call autoimmunity. So, it’s talking about the fact that the way they work is they help the immune system better recognize the cancer, and they do that by taking away one of the stop signals. But, that stop signal, the PD-1, PD-L1, that stop signal is also used by a lot of normal cells to tell the immune system to back off. So, when you remove it, when you block it, the immune system can get confused and start to attack normal cells. So, you can get a rash, people can end up with gut symptoms like diarrhea, they also can end up with it attacking the lungs and causing what we call a pneumonitis lung inflammation or brain symptoms, so, almost anything. Now, those are rare, and we can treat them with steroids. But, people need to be aware that if something new is happening, they need to alert their doctor. I think sometimes, there’s this false impression that immune therapy is completely safe, but, it’s not. And, all of the treatments that I’m talking about are designed to help people live better and live longer when they’re dealing with lung cancer, but they all also have risk.

And so, it’s just really important to have those discussions with the care team as you’re starting something new about what are the things I need to be watching for and to know how to reach people if you’ve got a new and concerning symptom, especially if you’re starting on something new.

Katherine:                  

That’s all really helpful information. Thank you, Dr. Wakelee. We have a question that we received from an audience member earlier. Jeff asks, “How do you know if your lung cancer treatment is working?”

Dr. Wakelee:              

So, there are a lot of ways of knowing if treatment is helping. So, the one I rely on the most is, “Does the patient overall feel better?” That is difficult to say exactly how. Sometimes people are having breathing problems; they feel that that’s better. Sometimes their energy’s lower. They feel better. It can be vague. We also use scans. So, we tend to get scans, depending on the treatment we’re giving, every couple of months plus or minus, sometimes, every three months to help track what’s actually going on. But occasionally, there are discrepancies.

So, sometimes, the scan, is it better? Is it not better? Can’t really tell. And then, you’re always taking that, “How does the patient feel?” So, usually, if the scans are better, the patient feels better. It’s easy. Usually if the patient’s feeling worse and the scan looks worse, clear decision. Not a good one, but clearly, we need to do something different. But sometimes, you’re left, and especially this happens with the first scan because you get a scan, it takes a little while, you start the new treatment, then you get the next scan, how much of the changes happened before you started the new one and how much didn’t? So, these can be more challenging conversations, but generally if the patient’s feeling a little bit better, the scan’s unclear, we usually say, “You know, let’s give this treatment a little bit more time.” We also, I think your question was specifically around how do we tell if it’s working, but, you also often need to be thinking about, “Well, what’s it doing that’s negative to the person and is that potential, those side effects worth the benefits we are or are not seeing?”

So, it’s kind of all of those things together. It can be a bit complex.

Katherine:                  

What goes into the decision to change therapies if it becomes necessary?

Dr. Wakelee:              

So, when we’re thinking about making a change, the way I always look at it is, is where we are today still okay or not? And, if it’s not, that would be because clearly the cancer’s growing or clearly the side effects are just not tolerable. Then, we decide together with the patient we need to do something different. And, when we think about what do we do next, we look at what have we’ve already done, did it work or not, if not, let’s do something more different. And so, let’s think about something that might be somewhat similar. When we’re dealing with targeted therapies, we have ways to try to figure out what changed in the tumor that made it now resistant or not working with that treatment. And so, with some of the pill drugs, there’s been a lot of research and understanding how does the tumor change that helps it evade, get away from, be resistant to whatever treatment you’re on.

And then, sometimes, we have other pill drugs that work in that particular setting, not always. With immune therapy, we’re trying to better understand why does the immune therapy stop working? Sometimes you can add back to it, like, you can add chemotherapy back to immune therapy alone or sometimes you can do radiation with immune therapy to get that response back. Or, add other combinations to it. So, that’s another thing that we’re working on. And then, like I said, if someone hasn’t ever had chemotherapy and the tumor’s become resistant, we’re going to be thinking a lot about chemo because that can play a role against so many different reasons that the cancer might not be responding to whatever treatments someone’s on. And then also, looking at how the patient’s feeling and doing, what their overall what we call “performance status, ” their sort of overall health, and how well do we feel with them that they’re going to be able to tolerate the next treatment because, you’re always having to weigh how much is this likely to help, and how might this harm in finding the right balance.

Katherine:                  

I’d be remiss if I did not bring up COVID-19, and, I’m sure a lot of patients are curious whether the vaccine is safe and effective.

Dr. Wakelee:              

So, we do believe the vaccine is safe and effective for patients living with lung cancer, and really important to be protected as much as possible. I was part of a group of other physicians around the world looking at the impact of COVID-19 on patients living with lung cancer. And, we collaborated with a group of physicians, Rayna Garcina was the lead. She was living in northern Italy at the time of the first wave, and so, was really face-to-face with it early on when there was so much we didn’t know. And, she gathered a group of us to watch and see, and what we were able to figure out before the vaccine was available was that people living with lung cancer who were overall healthy still except for their cancer were perhaps on a pill, targeted therapy, or immune therapy seemed to really not have that different of an impact compared to people who didn’t have lung cancer.

Chemotherapy was a little bit harder to see that, but didn’t seem to be such a big issue. It’s different than people living with, say, leukemias or lymphomas where the treatments are impacting their immune systems even more. They seem to have worse outcomes. A lot of lung cancer patients were okay, but still, it’s a higher risk. And so, we want to protect our patients as much as possible.

So, we are, now that we have the vaccines, strongly advocating vaccines for any patient who was living with cancer really for almost anybody because as a physician, we really think that makes a big impact. We have not seen any negative impacts of the vaccine on any aspect of cancer treatment. It does not have a negative impact on how well the cancer is treated by the therapies. We did notice that when someone gets the vaccine, they can get some enlargement of the lymph nodes. That’s part of having an immune response is your lymph nodes get enlarged. And so, we did get a bunch of scans that the vaccines came out showing, “Well, this person has some lymph nodes in the axilla, which is the armpit.”

And it seemed to be correlating with the side that someone had a vaccine. And then, those go away. And, this was actually an interesting medical literature thing because for people getting screened with mammograms for breast cancer, there were suddenly all these lymph nodes showing up. But that was actually a sign that the person was responding to the vaccine and it went away over time. And, it was a fine thing. It was just – I remember the first patient I had where that happened, we’re like, “Oh, well, that makes sense. Okay.” So, it’s okay. So, it was not cancer. It was just the immune response. But, yeah, so, we are recommending vaccines. There’s no data showing it is not working for lung cancer patients. The vaccines are less effective in people getting certain types of cancer treatment that are really suppressing the immune system. But even some response is better than none, and we’re still recommending the patients really do their best to stay safe with masks and things like that.

Katherine:                  

Dr. Wakelee, what are you excited about in lung cancer research right now? And, what do you want to leave the audience with? Are you hopeful?

Dr. Wakelee:              

I’m very hopeful. When I started treating lung cancer patients 20 years ago, we only had chemotherapy. And now, for metastatic disease, with using the right biomarkers, we can figure out so much more about the cancer to be able to personalize the treatment, for many patients, being able to offer pill therapies that are somewhat less toxic and highly active and give people more time. And now, we’re in the immune therapy revolution, which is helping a whole other group of patients living with lung cancer to be able to live with quality life for much longer. And the pace of discovery is just going up so quickly. And, I think that’s what I’m most hopeful about is just how much attention is being paid on lung cancer and finding better therapies that are going to help more people for a longer period of time. And again, I’m going to emphasize the screening is making a big difference also. If we can find the disease early, we can have an even bigger impact on people.

Transcript:

Katherine Banwell:

Well, let’s define a few terms that are often confusing for patients. What are biomarkers?

Dr. Preeshagul:

Those are somatic alterations in the tumor just like EGFR, or ALK fusions, or MET exon 14, or MET amplification, or KRAS G12C.

These are all genes that are altered in the tumor. And these are genes that drive the tumor to grow. There are also other markers like PD-L1, which is a marker for response to immunotherapy. And there are various markers.

I could go on and talk about it for hours, but those are the more common ones that we know how to treat and how to handle and prognosticate.

Katherine Banwell:

And another term that’s sometimes confusing, what is a genetic mutation?

Dr. Preeshagul:

So, for genetic mutations, you have germline, and you have somatic. So, a germline mutation may be something like a BRCA1 or a BRCA2 that we see in patients with breast cancer or prostate cancer versus a somatic mutation which would be EGFR that I had mentioned or ALK fusion. So, germline mutations are the ones that we worry about being heritable.

And somatic mutations are those that are not thought to be heritable but thought to happen spontaneously within the tumor itself and cause the tumor to grow. We are constantly learning more about these though, however. But it’s really important to talk with your doctor to see if you have a germline mutation or a somatic mutation or if you have both.

And it is never wrong to seek an opinion with a genetic counselor to make sure that everyone in your family is safe, that you’re up to date on age-appropriate cancer screening, and that your family gets screened appropriately as well if indicated.

Katherine Banwell:

Are there specific biomarkers that affect lung cancer treatment choices?

Dr. Preeshagul:

Oh, definitely. One that I had mentioned is PD-L1. And this is a marker that we look for expression. So, based on FDA approval for pembrolizumab, if you have an expression of 50 percent or more, you are able to get immunotherapy alone in the upfront setting. If you have less than 50 percent, we often give you chemotherapy plus immunotherapy. And that’s based on a clinical trial known as KEYNOTE-189.

Other markers such as EGFR, as I had mentioned, ALK fusions, RET, NTRK, MET exon 14, ROS1, KRAS, HER2, you name it, those are alterations that we look for ideally in the upfront setting as well and can really affect treatment planning.

And those patients that harbor mutations like EGFR and ALK and ROS1 or MET exon 14, we know that these patients do better with targeted therapy upfront, not standard-of-care chemo. So, it’s really important to know about the presence of these alterations before you start treatment if possible.

Katherine Banwell:

When it comes to lung cancer, Dr. Preeshagul, what important tests should patients undergo that help in making treatment decisions?

Dr. Preeshagul:

So, it’s important to obviously confirm the diagnosis and make sure that it’s lung cancer, first of all. After that, you need to know the histologic subtypes. So, I mean, is this non-small cell, or is it small cell lung cancer?

And the difference between those two, it’s very important. They are not the same. Their treatments are different. Their prognosis is different. The staging is different. Everything is different. If you have non-small cell lung cancer, it’s important to know if you have adenocarcinoma or squamous cell carcinoma, large cell, neuroendocrine. It’s really important because the treatments vary. The prognosis varies. And how we approach those patients is different.

In addition to that, over the past 10 years, we have really come to understand the importance of next-generation sequencing testing, which I know we’re going to get to. But evaluating to see if your patient harbors any mutations or alterations that could be targetable because that would really change your treatment plan.

Katherine Banwell:

All right. So, let’s get to some of that testing. What is biomarker or molecular testing?

Dr. Preeshagul:

Sure. So, we use a lot of these terms synonymously. So, alteration, mutation, positive biomarkers, these are all basically one and the same. So, if you look at lung cancer 20 years ago, we really didn’t know about any of these. You had lung cancer, you got X, Y, and Z chemo. And that really was it.

But with the discovery of EGFR alterations and realizing that some patients harbor an EGFR mutation, and this mutation is what’s driving their tumor and then the discovery of erlotinib, or Tarceva, we realized that it’s important to evaluate for the presence of these mutations.

So, these are somatic mutations that occur within your tumor and drive your tumor to grow, and some of these alterations are targetable.

But some of these alterations that we find, unfortunately, and the majority of them, we don’t really know the significance of them as of yet, or we know the significance of them, but we don’t have a magic bean to treat them. But that does not mean that there won’t be something in the future.

Katherine Banwell:

Dr. Preeshagul, when it comes to lung cancer research and emerging treatment options, what specifically are you excited about? 

Dr. Preeshagul:

So, honestly, I feel that my interest and excitement are getting pulled in a million different directions as of now. Over the past 16 months, we’ve had 10 approvals in lung cancer, which is unheard of. 

Katherine Banwell:

Wow. 

Dr. Preeshagul:

It’s been a very, very, very busy time for us as thoracic oncologists, which is really exciting. 

I feel that we’ve really come to the forefront of cancer research, which is outstanding. In terms of what makes me excited, right now, I think it’s probably two things. There have been genetic alterations, somatic, that have really been almost like the orphan child in lung cancer. And we have unfortunately had to tell patients, “Listen, you have this KRAS G12C alteration. We know that it portents a poor prognosis. We know it’s more aggressive, but we don’t have anything for you that can target that.” 

And as of recently, within the past two months, we had this approval for a drug called sotorasib (Lumakras). This is based on the AMG 510 study. And it is a targeted therapy for patients with KRAS G12C, and the responses have been excellent. 

So, finally, we have something. So, it makes me feel good that when I have a patient that unfortunately has this alteration, I no longer have to give them the same song and dance, that I can talk about sotorasib and talk about it with confidence and talk to them about the data. And the same thing is true for patients with an EGFR exon 20 alteration with amivantamab that just got approved. So, it is now, I feel, that research is now unveiling these orphan alterations that we are now having targeted therapies for. 

So, that makes me excited. Also, something else that’s making me excited is the fact that we’re realizing and learning to anticipate these resistance alterations. So, we know if you have an EGFR mutation for say, we know now that, unfortunately, at some point, the treatments that we’re going to give you, this targeted therapy, this pill called osimertinib (Tagrisso) in the frontline setting, for some patients, unfortunately, at some point, it’s not going to work for you anymore. 

And this is because the cancer gets smart. It develops these resistance alterations. It knows how to usurp the osimertinib, and resist it, and make an alternate pathway, or change its form, turn into small cell, or come up with another alteration that makes the osimertinib not work. 

So, we’re realizing to look for these alterations earlier, faster than when a patient starts progressing, and anticipating them. So, our trials are now being designed in a way with combination therapy to figure out a way to outsmart this cancer. We always have to be one step ahead. And unfortunately, cancer is still many steps ahead of us. But we are learning to be smarter.

 Katherine Banwell:

Dr. Preeshagul, let’s start with you introducing yourself, please.

Dr. Preeshagul:

So, my name’s Isabel Preeshagul. I’m a thoracic medical oncologist at Memorial Sloan Kettering Cancer Center, which is a large academic cancer center in the Northeast. And I’m part of a group of 24 thoracic oncologists.

I specialize in treating patients with non-small cell lung cancer, small cell lung cancer, mesothelioma, and some other thoracic malignancies but most really just focused on lung cancer. I have a very strong research interest in predictive markers for response to immunotherapy as well as targeted therapy.

Katherine Banwell:

Excellent. Thank you so much. What are the considerations when choosing a treatment for lung cancer?

Dr. Preeshagul:

So, that is a very weighted question. And I could talk about that for forever. But to try to be as succinct as possible, the most important thing is to really look at who you’re treating in front of you and try to treat the patient as a whole. It’s not only their diagnosis and their histologic subtype and their stage that’s important.

You really need to think about what’s important to the patient. Is someone a concert pianist or a violinist and giving them a treatment that could potentially cause neuropathy, could that be life altering for them? Or, are they of child-bearing age? What are their priorities?

So, that’s really important to me. Social aspects of a patient’s life, religious aspects, beliefs, ethical beliefs, all of that you need to take into consideration. And then getting more granular, you need to know about the tumor biology.

Do they have any driver alterations? Do they have any other predictive markers that may help you plan your treatment? So, it’s a lot of different things that go into treatment planning.

Katherine Banwell:

Just remind us what neuropathy is.

Dr. Preeshagul:

Sure. So, neuropathy is when the nerves that are in, I guess you could say, your fingers and toes start to damaged.

This can happen from diabetes, from having glucose that is too high for too long, or it can happen from certain chemotherapy agents that can affect the fine nerves in your fingers and toes and cause them to go numb. And this can really be painful. It can be life-altering. It can keep you up at night. It can make your sensation decrease.

So, if you’re walking on the floor, you may not feel a fine, little nail, or you may not even really feel the floor. And if you’re really focused on using your hands for playing the piano or violin or sewing or even any other kind of activity, it can really affect how well you’re able to perform.

Katherine Banwell:

Yeah. What is the role of the patient in making treatment decisions?

Dr. Preeshagul:

So, I think every doctor will give you a different answer for this. But for my practice, I really make sure that the patient is part of the team as well as family members, as long as the patient gives permission. I run everything by the patient, of course. I give them all the possible options ranging from ones that I think would be most efficacious to ones that I think are other options and of course, the option of no treatment, which is always an option, and sometimes, the best options.

So, I really say these are the things that we can offer you, but what do you feel most comfortable with? What’s important to you? And sometimes, patients are taken aback by this question because some patients like to be told, “Well, this is what we’re going do, and this is when we’re starting,” and X, Y, and Z. That’s not how I practice.

And it’s really important to me that the decisions come from the patient but are guided by me and my team.

Katherine Banwell:

Why is it important for patients to feel like they have a voice in their treatment?

Dr. Preeshagul:

So, that is such a good question. And I think a lot of it comes from the fact that you have a patient that had a completely normal life and all of a sudden get delivered this life-altering news that they have cancer. And everything that they had control over just seems to completely go out the window just in a matter of seconds.

So, making sure that a patient is back in the saddle and has control again and feels like they know what the next steps and feels like they know what they can expect is really important to them from what I can see. And I think that is something that allows them to feel like they’re a little bit more like themselves again.

They come to meet me. They don’t know anything about lung cancer. Their world has been completely rocked. And when they know their treatment plan and they know their stage and they know what to expect and they’re kind of a little bit more on autopilot, I can see in some patients them being able to exhale a little bit and feel like they’re in control again, and they know what – every Monday, I’m going to come and see Dr. Preeshagul. I’m going to get my treatment. I might not feel so good the next couple days, but I know the week after and the week after that, I might feel a little bit better. And they kind of are back in control again.

Let’s talk about patient self-advocacy. Patients can sometimes feel like they’re bothering their healthcare team with their comments and questions. But why is it important for patients to speak up when it comes to their symptoms and their side effects?

Dr. Bauman:                

So, this, I would say, it’s a partnership. The bottom line is, and if I don’t know that something is going on, I can’t help to solve the problem. And if I don’t know about something, a new symptom that could be, potentially, majorly concerning, patients can also get really sick or even end up in life-threatening situations. And so, ignoring things or just hoping things will go away is not in a patient’s best interest.

I think that it is critical that patients are their own self-advocate. I think that I say that often, and I’ve already said that a couple of times on this, but we don’t know unless we’re hearing from them what’s going on. And so, it is so important for patients to keep us updated if they’re worried about something. Certainly, we see them very frequently, and so they can often tell us at their visits what’s going on. But overall, the in-between time is just as critical because it is often the treatments that we give can cause side effects at any time. And so, it is really important that we know about anything that’s going on and for patients to always give us a call.

I mean, that’s the bottom line is, is that if they’re worried about something, we need to know about it.

Katherine:                   

What supportive care options are there for patients who may have pain management difficulties or even emotional support? Where do they start?

Dr. Bauman:                

So, there are often many different kinds of supportive care for patients. I would say that oncologists, of course, are one layer of supportive care. We do a lot of help with symptom management and often even pain management as well as coping and emotional support. However, there are also other people often within cancer centers that are also available to help. And this includes social workers. It also includes psychologists and psychiatrists.

And then the other thing that I think is really important to mention is that we know for patients who have lung cancer or an advanced lung cancer diagnosis, that integrating a palliative care team – a supportive and palliative care team – early into their diagnosis actually helps them live longer as well as better.

They have better quality of life, and they have decreased problems with mood.

And so, we know that supportive care and palliative care, specifically in lung cancer, is particularly helpful for both patients and their caregivers. And so, it’s important for patients to also know that there is a whole team, that I think of as, sort of, an extra layer of support, that can help them with symptom management as well as with coping with the day-to-day of what can be a devastating diagnosis.

Once a patient has started treatment, how do you know if it’s working?

Dr. Bauman:                

So, we do regular imaging. So, once you have a diagnosis of lung cancer, a CAT scanner will become your friend. In general, depending on what stage of lung cancer you have, you will have a bunch of imaging up front, and then once a treatment plan is put into place, after that treatment has either been completed or started, you will be monitored, in general, regularly for the lung cancer diagnosis. Now, after surgery, that will be for more for surveillance to make sure that the lung cancer doesn’t come back. But if it is more in the setting of a stage IV lung cancer, then the imaging really helps us determine, “Is the treatment working or not?”

And so, after we start a treatment, usually anywhere between six and eight weeks, we repeat imaging to see, “Is this working? Is it smaller? Is it the same? Has it grown?”

And based on that imaging, and based on how the patient is doing with the treatment, we then decide, “Do we continue this treatment, or do we need to change to a new treatment?” And so, we regularly monitor the patient’s cancer through regular imaging.
