What Are the Latest Lung Cancer Treatment Updates?


Transcript:

Dr. Nicole Rochester: 

Hello and welcome. I’m Dr. Nicole Rochester, I’m a pediatrician, a professional health advocate, and your host for today’s Patient Empowerment Network program. We are so happy that you tuned in. How can you access the best possible lung cancer care? What do the latest combination therapies mean for you? Should you consider a clinical trial as a path to enhancing your lung cancer care? This Best Lung Cancer Care program focuses on providing actionable steps to achieving equitable care and connecting to patient-centered care on your path to empowerment. We are joined today by international lung cancer expert, Dr. Christian Rolfo, Professor of Medicine and Associate Director for Clinical Research in the Center for Thoracic Oncology at the Tisch Cancer Institute. Thank you so much for joining us today, Dr. Rolfo.

Dr. Christian Rolfo: 

Thank you, Dr. Rochester, for having me. It’s a pleasure to be here. 

Dr. Nicole Rochester: 

Wonderful. I’m looking forward to our conversation. Now, following this program, you will receive a survey and we would be thrilled to get your feedback because this helps inform future lung cancer programs we produce. Please remember that this program is not a substitute for seeking medical care, so please be sure to connect with your healthcare team regarding the best options for your care. Now, let’s delve into this very important topic, how can I get the best lung cancer care? And, Dr. Rolfo, we’re going to start with an overview of the lung cancer treatment landscape. We know that this landscape is rapidly changing and keeping up with the pace of developments could be a challenge not only for doctors, but certainly for patients and family members, so I was hoping that you could give us an overview of the current lung cancer treatment landscape.

Dr. Christian Rolfo:

In the last year, lung cancer treatment was changing radically. We have actually, including some of their new concepts as precision medicine or personalized medicine, that we have actually different therapies that are specifically for some group of patients, that they have specific alterations in their tumors. And when I’m talking about alterations I refer to mutations, genomic alterations that can be targeted nowadays with specific medications, and currently, some of them are actually, the majority of them are actually pills, for example. So it was changing radically and we are not using it like before chemotherapy for everyone. Another area of important interest was the introduction of immunotherapy, this is also an important tool for fighting cancer, and there you have a substance that are administered generally, all of them are intravenous, and this is the principle of that is to await from your own inner system, from the patient immune system, they are the tools to fight against the cancer, so it’s a very innovative way to approach cancer, and this is.

The good thing is that these two approaches targeted therapies, immunotherapy, and also still obviously the combination with chemotherapy in some of the case with immunotherapy, we can use not only metastatic patients, so in patients who have advanced disease, but also we can use in patients who have earlier stage that they were operated, for example, and we want to prevent that this patient is not going to a further process of cancer metastases, or there are several, several innovations. Then we have innovations that are coming also from local treatments and we call local treatments the one that, for example, surgery or radiation, we have new technologies also that are arriving there, and the combination sometimes with the medical treatment or systemic treatments that are going everywhere that is the description of systemic are helping these patients to have not recurrence and improving. Actually, lung cancer survival was really improving in the last years, and we are very excited by that because, unfortunately, it’s very still an aggressive disease that we were able to change with all this armamentarium the prognosis of these patients.

Dr. Nicole Rochester:

Wow, that’s a lot. I mean it’s exciting to hear that there are so many new developments on the horizon and that so much has happened just in the last year as it relates to therapy. What have we learned about drug resistance as it relates to non-small cell lung cancer? Are there any new developments in that area?

Dr. Christian Rolfo:

Yeah, obviously the patients of the…as I just commented, we have different patients with different needs and different scenarios, so we are now fragmenting a lot of the diseases and we have actually different diseases, and one big disease that is the lung cancer, so now we are treating patients in a different way. And some patients have, for example, patients who are under treatment with targeted therapies, they can develop mechanics of resistance that we can nowadays not only identify but also treat. 

So we can treat and change the recurrence of these patients. One of the tools that we are using for that is liquid biopsy, for example, that is this blood draw that we are going for the patients, and actually, we are trying to do this determination from the very beginning and also monitoring the patients after we have this information to see if we are able to determine the mechanics of resistance, see also the outcomes of some of the therapies and change the treatment when it’s necessary. In immunotherapy, we have alterations that are resistant or refractory, that is another way of definitions so refractory we say patients that are not responding during the treatment and resistance of patients that or simply patients that are after the treatment having a progression in a very short time, so we need to identify these two categories and try to treat them in different ways that we have armamentarium for that as well.

Dr. Nicole Rochester:

Wonderful, thank you for that. So you’ve mentioned a lot about updates, are there any other exciting updates that patients and families should know about related to lung cancer, maybe things that are in the works that we may hear about in 2023?

Dr. Christian Rolfo:

Yeah, I said, for example, liquid biopsy I was mentioning liquid biopsy, and we are focused obviously, and in patients that have advanced disease or when they have this disease that is already confirmed. But we are now moving the tools that we have to the dedication of cancer using liquid biopsy from the very beginning, so we can use a minimal residual disease that is patients after the surgery. And I think I hear answering one of the questions that we have in the chat that this minimal residual disease is the quantity of two more that sometimes we are not able to see in the images or is very tiny, and we have equivocal information, the possibility to discover the patients that after surgery, have the possibility to recurrence or have come back of the disease is really important. 

And also we are looking for early detection of lung cancer trying to identify patients with the high-risk populations that they are maybe having the opportunity to be in lung cancer screening because they are smokers, or because they have all the characteristics on top of this model that we can also use the liquid biopsy there. But one of the most important messages that I want to say, because I mentioned it here smokers and I want to remind you that we have a big proportion of patients around 20 to 25 percent of the patients that they never smoked and that they can develop lung cancer, so we have a motto, we say if you have a lung, you can have it because we want to break this stigma that lung cancer has the only patients who are smoking, obviously, smoking and tobacco are related highly with lung cancer. 

Dr. Christian Rolfo:

But also we have patients that are second-hand smokers or they have other causes of lung cancer, so we need to be aware and we need to try to get attention for that because, in this special population of non-smokers, we know that there is a special characteristic that we can treat them completely different, so it’s very important that we identify those patients as well.

Dr. Nicole Rochester:

I really appreciate you sharing that, Dr. Rolfo, because as I’m sure you know, there’s a lot of stigma associated with lung cancer and the assumption that if you have lung cancer, then that automatically means that you are a smoker, and not that we know that people who smoke, those are challenges, but to just acknowledge that not everybody with lung cancer is someone who is a smoker, and also that the approach, the treatment approach may be different, so I really appreciate you pointing that out.

Dr. Christian Rolfo:

And actually Dr. Rochester, you know this stigma was causing several domino effects. We have less funding for research, we have less support from the community sometimes like other tumors have, for example, breast cancer. So if we are looking specifically in lung cancer, the quantity of women that are dying or are going to a diagnosis of lung cancer, it’s very impressive, but actually it’s killing more people sometimes than other tumors. So we need to be very careful with this stigma because we need…and this is a call for action, now we need more funds, we need more support from the community, because this is a very important area that will need research.

Dr. Nicole Rochester:

Absolutely, so that brings me to the next section of our program, you’ve mentioned a lot of these therapies already, I just want to go a little bit deeper into exploring some of the lung cancer treatment strategies and also talk about clinical trials, so you talked about bio-markers. Can you expand a little bit on that? We know that no two lung cancers are the same. Can you explain to the audience how biomarkers help with lung cancer treatment and they can be so important? 

Dr. Christian Rolfo:

Yeah, we have different…as I say, we are looking at specific characteristics from the tumor when I’m referring to genomic alterations that I’m not referring to something that you can get from your family and bring to your descendants. So I’m talking about mutations that are occurring inside the tumors and only for the tumor, and so affecting only the subject that have this patient that has this alteration. So these biomarkers are an important way to identify populations that we can treat specifically, and I would like to be a little bit more specific on that. We have some of the alterations, for example, one of the mutations that we call EGFR or epidermal growth factor receptor mutation that is supported in different populations in different frequencies. 

For example, if we have patients that are with an Asiatic origin, we have there the possibility to have a…and I’m referring, for example, Chinese, Japanese, this area of the East Asia, we have a hyper-prevalence of these mutations in around 50 percent of the patients with lung cancer, non-squamous we’d say this is another characteristic of the tumor can have this specific alteration. If we are moving, for example, to Latinos, the pains of the areas of Latinos they are coming from, if you have Mexican or for example, Peruvian, they have also due to their ancestry, they are similar to the Asiatic population, 40 percent we’re going to white populations and Anglo-Saxons or Europeans, they have around 7 to 15 percent according to the different regions. 

African-Americans within 15 to 20 percent. So these kinds of alterations are giving us the opportunity to treat and we have nowadays inhibitors and that’s drugs that are from first, second and third generation, so we were evolving in January, this pharmaceutical in January to develop all drugs that are able to penetrate in the brain and acting not only in the tumor, but also in brain metastases. And patients who have this mutation, for example, are treated in first line, in front line, or the first treatment that they receive are pills, no chemotherapy. 

So for this reason, and that is something that is important because when we know that patients, when they start this journey of lung cancer diagnosis before they see an oncologist, they were struggling to get the diagnosis and then we’re passing through several doctors from the general practitioner or to the emergency room, going to CT scan and then a biopsy then a pulmonologist until they get the diagnosis, it’s a big period of time sometimes that we are very nervous because we want to each patient to have a treatment as soon as possible, and sometimes when they arrive to us, we say they need to wait until we have the results of these biomarkers.

So it’s difficult to understand, I put in the place of the patients and the families are really difficult to understand that I was passing a lot, I went here, I came here and I want your treatment right away, but this period that we are asking to wait is really important because we will have information that can change radically the treatment and the history of these patients. So one of the problems that we have in America is the lack of testing, so we have all the tools to test the patients, but if we are looking at some of the statistics, 50 percent of the patients have been tested…39 percent if we are moving to groups, for example, of African-Americans, so we need to be very careful that don’t push to get the treatment very quickly without having all the elements to this thing, which kind of treatment is the most adequate for the patient. 

Dr. Nicole Rochester:

That is such important information, and I really appreciate that, I appreciate it. That you put it in the perspective of the patients and family members. And that grueling, long wait, long time to diagnose this, and finally you’re in front of a specialist and the perception is that, Okay, now I’m going to get this treatment that I need, and then like you said to hear, now you have to wait a little bit longer, but also to understand that that wait is important to make sure that you get the treatment that is meant for your specific type of cancer, I think that is so incredibly important.

Dr. Christian Rolfo:

And believe me, we are trying to push as well from the that there are unfortunately technical times that we cannot overcome that are for testing and for having these results, and we can do that by like I said liquid biopsy, but also tissue biopsy, so we are sending the tissue that the patients gave for a biopsy in a biopsy or in a resection when they have surgery. We take these small biopsies and we send them for analysis and take longer sometimes, so it’s a pity, and we know but it’s the only way to go for the right treatment.

Dr. Nicole Rochester: 

So with regard to the biomarkers, you mentioned that these are kind of unevenly distributed among different populations depending on your origin, and so how does that play into the progression of the disease, what do we know about why patients with specific biomarkers have a different degree of disease progression?

Dr. Christian Rolfo: 

Yeah, so we know more or less that the characteristics, I mean more or less in terms of the evolution of the clinical characteristics of these patients, in terms of organ affection in case of progression, but what is most important of this is that we are able to continue to identify, and I say monitoring these patients with liquid biopsy for example, this is a good tool to understand or to understand it a bit better, which kind of mechanistic involvement. So because we have, for example, patients who were receiving the case that I was discussing before EGFR mutations and they received one graft from the very beginning, a third generation TKI is the one that is approved for the first line, and this patient has a progression.

 The possibility to have a mechanism of resistance is different, so we can have mutations that are coming in the same pathway, so in the same area, same kind of mutation, but different location, just to the people understand is the kind of line and we have the mutation that is here, the one that we are attacking, but we have another mutation that is in this area and it’s not covered by the track that is covering this mutation. 

Dr. Christian Rolfo: 

So we have nowadays drugs that are going to, in this area in clinical trials, or we have in other cases other areas of the task of mutations that have nothing to do with the original one. So we are activating another kind of pathway, or we are transforming the tumor from one kind of tumor to another kind of tumor, so for this reason, identify which kind of mechanism of resistance is in place can have an important or have important implications for how we are treating these patients, so we need to look at that to treat the patients.

Dr. Nicole Rochester: 

Wonderful. And speaking of resistance, we know that there are some patients who end up trying multiple therapies in order to treat their lung cancer, are there alternative treatment strategies for lung cancer patients who have failed all therapies? 

Dr. Christian Rolfo: 

Yeah, absolutely, we have research in lung cancer is never stopping in oncology generally, but in lung cancer it’s really exciting to see how this research is evolving and it’s arriving to the patients the meaning of the research when we are doing access to the patients, to the discovery of the finding that we have, and obviously, we have strategies in the clinical practice, but also we have the clinical trials. So clinical trials, and that is something we need to try to define very well because some patients believe that when we are going to clinical trials there are no more options or we don’t have any other options to do. We are sometimes using clinical trials even in the first line, so even in patients that are for the first time being treated. 

Because we know that some of the cases we are treating patients with from some standard of care and using drugs on top, we want to explore it, we can improve these outcomes that we already know. That could be also a clinical trial, that is also a clinical trial. So don’t take the participation in a clinical trial as the last option that you have, sometimes you will go to your doctor and the first time that you see a doctor for your first diagnosis, they can propose a clinical trial. 

And this is really valuable. What we really appreciate is the collaboration of the patients to be in clinical trials, because we need to remember that the drugs that we are using today were analyzing other patients before, so the treatment that you are receiving in a standard of care today were before a clinical trial, it’s really important how we can interact with the research and the clinical practice very easily, so we have also some options that are…for what we call early drug development, that there are some drugs that are in patients who are receiving the standard of care, and they have the opportunity to be treated in new drugs, and you can discuss…believe me there, and 

I know that there is a lot of questions about clinical trials but the clinical trial setting is really restrictive, it’s very well-coordinated, so you would be part of a very coordinated and structured things that they try to protect the patients in the first instance, and try to understand also how we can help the patients and the future generations. So that is really why we appreciate patients, that the contribution of patients that are giving to this clinical research because it’s helping to advance the knowledge for the new patients as well.

Dr. Nicole Rochester: 

And I really appreciate how you described clinical trials, and particularly your distinction about it’s not always this last-ditch effort that sometimes you all are using clinical trials as first line therapy. One of the common things is that clinical trials are tomorrow’s medicine today, and helping patients and families to understand that there’s value in being involved in clinical trials and that…and I think with COVID there’s a little more understanding, but certainly, we have a long way to go, and so I appreciate you sharing that. Do you have any specific examples of patients in your practice, and not names of course, but examples of…that have benefited from clinical trials?

Dr. Christian Rolfo: 

Absolutely, we have several of examples and actually FDA was doing a terrific job in the last year to try to get access quickly access to the drugs for patients, and some of this access that was granted was based in clinical trials that we’re starting for a phase one or phase two trials, so we are really doing a very rapid evolution of the drug development, and this is a revolution actually of the drug development because we have access very quickly. I can tell you that it was certainly in my career, several patients in clinical trials that they got benefits. Obviously, clinical trials are answering questions, so that is the way that we can answer questions scientifically and is the only way that we can advance in clinical therapeutics. 

Dr. Nicole Rochester: 

Wonderful. So I want to move into treatment access, we’ve talked a little bit today about some of the differences that we see in lung cancer with regard to the biomarkers, you and I know, and I’m sure that was in the audience, know that health disparities are widely reported here in the United States with really any all conditions, including lung cancer. So I’d love for you to talk a little bit, Dr. Rolfo about some of the challenges related to appropriate access to lung cancer care as it relates to different socio-demographic populations, and then how can we begin to address those disparities.

Dr. Christian Rolfo: 

Yeah, this is a topic that is really in my heart because I was coming with you before we start the communication, the recording of this. I was working in Europe before coming to the United States. I was shocked by the disparities that we see in some healthcare situations, so in my position before in Europe, we have a healthcare system that discovering for patients and we have, obviously, difficulties, but here I saw in some communities really underserved in terms of access to different service and healthcare is one of them. So we need to be conscious about that when we have patients that are struggling to get transportation, we have patients that are struggling to get approval for some drugs. 

So, there are a lot of areas that need to be addressed, disparity also in terms of language, we have also patients that are not understanding the doctors,  we have patients that are having difficulty when to get to the app information when we are saying, “Oh, you can see your report in your app,” so it’s not easy for some of them, we have generational gaps as well, these are disparities as well. So taking or being conscious of all these factors is making us take action and how we can take actions in our institutions, and in several institutions in the country, we have the support of an experienced team that is addressing that and teams are specific that are working for disparities. Some of them are social workers, some of them are advocate patients, so we have a big team of institutions that are helping to the patients to go for different scenarios, and even we have patients that are homeless, so how we treat patients in these conditions when we know that the patient is in a shelter, so if you have toxicity, what will we be doing. 

So all these things are taken into consideration, believe me, because it is like New York, you have a big disparity of or a big diversity, and we say of populations in one consultation morning, you can see all of them in your waiting room, so we need to try to address all this, and there are politics that are coming from us as a healthcare system, but there are also politics that they need to come from governmental politics, so try to use these…all the tools that we have at our disposal are important, and also we have a very good support of advocacy groups. 

Dr. Christian Rolfo: 

And this is something that I want to really profit their patient to say thanks because we have several, several advocacy groups that are doing a terrific job from testing to helping patients to go through this journey. So it’s really an important job, and obviously families, families are helping to these disparities and patients, so patients themself. So what I say always to the patient, raise your voice, empower yourself.

 Try to ask for your rights if you don’t understand your doctor… Ask again, if you want to have a second opinion, talk to your doctor, that is the most important thing. We are very open to help the patients, and that is our mission. So if I say to my patients, If you want to have a second opinion, please let me know, and I try to direct you to somebody who is an expert in the field and can help us to learn better your disease or your treatment, but I think it’s a situation that everyone is winning, especially the patient, but also ask for future patients understanding better every case.

Dr. Nicole Rochester: 

Well, as an independent patient advocate, myself, Dr. Rolfo, I always get super excited when physicians like yourself are talking about and emphasizing the importance of patients and families advocating for themselves, so I just want to reiterate a couple of things that you said just to make sure that our audience heard it very clearly and asking questions is one of the things that you said that is, I believe one of the most important ways that we can advocate for ourselves and for our family members in healthcare settings, and I really appreciate that you offer advice around second opinions.

A lot of people feel that they are sending their doctor if they ask for a second opinion, but a confident doctor like yourself and a good doctor is going to encourage that, particularly if the patient or family just needs that extra reassurance, so I just really appreciate that you brought that up. Before we wrap up, there are a few questions from our audience that I would love to present to you, and so one of them comes from MacKenzie and MacKenzie asked, can you speak about MRD testing and what that means for lung cancer?

Dr. Christian Rolfo: 

Yeah, and that we were discussing briefly. So minimal residual disease is the… As I say, when we have an operation, we can have the opportunity to have completely resected a tumor, but we don’t know more than with the CT scan when the patient will recover. So we are without an answer believing every follow-up visit what has happened, seeing if it has gone). So we are trying to reduce this…reduce the anxiety first of all, to try to get the tools that are able to identify patients that they can recurrence, have a recurrence so liquid biopsies, one of them, and we have now the several methods that are trials and several data coming that there are some companies that actually they are a market for some of the options, we are still having validations,  required validations, but we will certainly be there very shortly in time to identify these patients and to treat them in the proper time.

Dr. Nicole Rochester: 

Wonderful, and I think you just addressed a question that came in from Herald, which was is liquid biopsy playing a role in monitoring disease recurrence in lung cancer?

Dr. Christian Rolfo: 

Sure, we are actually tailoring treatments and checking the patients, and I have several, several experiences in patients that they’re monitoring over the time, and we have actually some of the vendors that are proposing this approach monitoring, liquid biopsy is a great tool because it’s minimally invasive, it’s just a blood draw and we can continue. Not all the patients have the possibility in terms of they are not all cheaters, that is something we need to know DNA, so it’s the majority of them, we can do it in some minimal proportion, we cannot do it when there are also possibilities to follow them.

Dr. Nicole Rochester: 

Excellent, and our last question from the audience comes from Laura, and she wants to know, “Are immunotherapy combinations in the metastatic setting, expanding to treat earlier stage lung cancer?”

Dr. Christian Rolfo: 

Yeah, absolutely, we have actually an FDA approval for us, one of the immunotherapeutic drugs in patients after the resection of the disease with some characteristics, but we are there and actually we are having more and more clinical trials using in earlier stages so we will say in the other stage from the earlier stage from that is the neoadjuvant and we call that when we are doing a treatment to reduce two months to be operated later on, so we have also some trials that are going there, but we have an approval already for the adjuvant setting that is after the surgery in some patients.

Dr. Nicole Rochester: 

That’s wonderful. You’ve given us a lot of good news. A lot of hopeful news, Dr. Rolfo, it is time for us to wrap up. I want to thank you again for being here for sharing your expertise. In closing, is there any takeaway that you want to leave with our audience today regarding lung cancer and advocating for themselves.

 Dr. Christian Rolfo: 

I will say that, first of all, thanks for the opportunity and it was a pleasure to discuss with you and I’d write to the population and say, Try to ask for your rights as a patient, so ask for your rights, be proactive in terms of your disease, you are the main actor here,  we are tools of trying to help you to arrive to the destination, but the good important thing is to create a good relation with your doctor, and to create a good relation with your doctor is part of the trust from both sides, so having an open communication… Open communication with the family as well. Sometimes we are smuggling or hiding things as a patient for our families to don’t help them, and vice versa that is not helping in this process, absolutely. And if you want, if you have that asking if you’re never deserving, so this is what we are here and all the team is here to help you.

Dr. Nicole Rochester: 

Wonderful. Well, I just want to echo what Dr. Rolfo said about asking questions about being an active member of your medical team, the doctors are there to assist you, but you are ultimately the expert for your disease for your body, so I just wanna thank you again deferral for being here for sharing such important information thank you all again for tuning into this patient empowerment network program. If you’d like to watch this webinar again, there will be a replay and you will receive an email when that recording is available, and remember, following this program, you will receive a link to a survey, please fill out that survey. Let us know what was helpful so that we can serve you better in the future to learn more about lung cancer and to access tools to help you get the best care no matter where you live.

Key Factors That Guide Myeloma Treatment Decisions


Transcript:

Katherine:

We know that patients undergo testing when diagnosed. How do test results affect treatment choices? 

Dr. Alsina:

So, in general, we do a bone marrow, we check for the genetics of the myeloma cells, see what are the genes that are affected in the myeloma cells, and that helps us define myeloma as high-risk or standard-risk, and that can help us decide what treatment we want to give these patients. Unfortunately, it’s not totally well defined. 

I wish we could use that in a better way and there are drugs that could really target, but there is some information. We know, for example, that proteasome inhibitors are important for patients with high-risk myeloma, so we definitely try to include that in a patient that is high-risk, and the other thing is that patients that are high-risk, it’s even more important to get to that remission, so we’re going to push treatment to get there, treat these patients a little bit more aggressively. 

Other than that, depending on, for example, what are the blood counts – some patients have a lot of bone marrow involvement and their blood counts are very low. This is not common, but it happens, and so, when that happens, we might be more aggressive up front and give these patients more aggressive chemotherapy to clean the bone marrow before changing them to the more normal therapies because the treatments that we give, like Revlimid (lenalidomide), Velcade (bortezomib), Darzalex (daratumumab) can depress the counts, right? 

So we’re in that battle. The patients already have low counts, we give the treatment, the treatment lowers the counts further, so it’s hard to give these treatments in these settings. And then, the third thing that we take into account is kidneys. About 25 percent of the patients will have renal insufficiency when they are diagnosed. Some of these drugs, particularly the immunomodulatory drugs like the Revlimid are metabolizing the kidneys, so it’s very hard to dose these drugs when the patients have renal insufficiency. 

So sometimes, for these patients, we avoid the IMiDs up front. We give a different combination until the disease gets better, and then we introduce the IMiDs. We think these immunomodulatory drugs like Revlimid are super important in the treatment of myeloma, so we want to give them, but sometimes we have to delay starting them until the patient’s kidney function improves.  

What Testing Should Take Place After Non-Small Cell Lung Cancer Treatment?

What Testing Should Take Place After Non-Small Cell Lung Cancer Treatment? from Patient Empowerment Network on Vimeo.

It’s well-known that patients should undergo testing before choosing lung cancer therapy, but what testing should take place following treatment? Lung cancer specialist Dr. Tejas Patil, from the University of Colorado Cancer Center, discusses the role of testing after treatment.

Dr. Tejas Patil is an academic thoracic oncologist at the University of Colorado Cancer Center focused on targeted therapies and novel biomarkers in lung cancer. Learn more about Dr. Patil, here.

Lung Cancer Targeted Therapy: What Is It and Who Is It Right For?

Why Do Lung Cancer Patients Need Molecular Testing Before Choosing Treatment?


Transcript:

Katherine:

We know that patients should undergo testing before choosing therapy, but what testing should take place following treatment? 

Dr. Patil:

That’s a really good question. And it’s a complex question depending on the type of treatment that the patient is receiving. So, broadly speaking in lung cancer, we’ve separated the field into two types of treatments.  

Patients with lung cancers will get molecular testing at the onset, right? When they’re diagnosed to look for what’s called a driver oncogene. So, these are mutations that can be targeted with pill-based treatments. And if patients have these mutations, there’s about 10 of these right now and several in development, then the patients can receive a targeted therapy.

However, if they don’t have these mutations, then the standard of care right now is some kind of chemotherapy with immunotherapy. Now, the question asked was what kind of testing do you do after diagnosis? And that really depends on which camp you’re in. So, if you’re in the targeted therapy camp, my general practice has been to repeat molecular testing upon progression. The reason is that patients who are receiving targeted therapies typically evolved some kind of resistance to targeted therapy.  

Broadly speaking, you can categorize these as on target or off target resistance, but the major reason for doing repeat molecular testing is to understand a mechanism of resistance and then hopefully develop a new treatment with that knowledge. Now for the camp that doesn’t receive targeted therapies, let’s say they receive chemotherapy and immunotherapy, there it gets a little bit more nuanced.  

And if there is a role for repeating a biopsy and looking for dynamic changes in the patient’s cancer, but it is not routine and should be done with consultation with a thoracic oncologist. And really the idea here is that if patients who are on chemo immunotherapy progress, any additional molecular testing should really help inform what the next line of treatment will be and sometimes that can be a clinical trial.

What Testing Should Take Place After Non-Small Cell Lung Cancer Treatment?

Katherine:

Biomarker testing is important prior to choosing therapy for non-small cell lung cancer. What is this test and how long does it take to get results? 

Dr. Patil:

That is a great question. So, a biomarker is a biological molecule found in blood or other body fluids or tissues that is a sign of a normal or an abnormal process.  

Or let me reframe that as it represents having some kind of medical condition or disease. Now, it’s a very broad definition. Basically, a biomarker can be used to see how well the body responds to a treatment for a disease or a condition. And when we look at it from a genetic perspective, sometimes the term that you’ll see is a molecular marker or a signature molecule.  

So, these are terms that are sort of interchangeable with biomarkers. But the role of a biomarker is to help ascertain how well the body responds to a certain medical intervention, broadly speaking. 

Katherine:

Okay. What question should a patient ask their doctor about test results? 

Dr. Patil:

So that’s a very complicated question, and I will do my best to answer it succinctly. So, my personal view is that for any test to be meaningful, it should impact medical decision-making in some very concrete way.  

Specifically, with biomarkers, the result should either be prognostic or predictive and I’ll define what those terms are. So, a predictive biomarker is one that helps determine if a certain therapy will be effective. So, I’m going to use lung cancer as an example. In EGFR mutation in non-small cell lung cancer allows a doctor to prescribe an EGFR targeted therapy called osimertinib (Tagrisso). Therefore, in this example, the EGFR mutation is predictive.  

It opens the door for this targeted option that would otherwise not have been available if the patient did not have this EGFR mutation. A prognostic marker is a little different. This is the type of marker that helps categorize risk. So, in the same example I used earlier, that patient may have an EGFR mutation.  

They can also have a different mutation called TP53. Now this TP53 mutation doesn’t influence therapy. It’s not targetable, but it does influence risk.  

And so, there’s been a lot of emerging data to show that patients with TP53 mutations have worse outcomes on targeted therapies than patients without TP53. And in that case, that mutation is what we call a prognostic biomarker.

Katherine Banwell:

What is immunotherapy and how does it work to treat bladder cancer?  

Dr. Anari:

So, immunotherapy, the analogy that I often use when I see patients is immunotherapy goes in by IV, and it acts as the drill sergeant. And it trains your own body’s immune system or the soldiers to find and fight the cancer cells. So, that’s really how it really works. The drug itself is training your own body to do the work. 

Most people will have no side effects from this. And they tolerate it really well. However, because the immune system is getting a little bit activated, sometimes those soldiers or your immune cells can go rogue. And they can start attacking normal healthy tissue in the body, almost like an autoimmune disease. 

So, when on these drugs, it’s really important if anything is new or different to let your doctors know, because it’s often easy to troubleshoot over the phone or at a quick office visit if it’s related to immunotherapy or not. So, it’s really important that you keep that in mind whenever a new symptom or anything may pop up.  

Katherine Banwell:

That’s great information – it’s really important to communicate any issues you may be having. So, who is immunotherapy right for? Is it right for every bladder cancer patient?  

Dr. Anari:

So, immunotherapy is used in several different settings for bladder cancer treatment. It’s used in the metastatic bladder cancer treatment world mostly. Often, we use it as either a second-line treatment after chemotherapy or in a maintenance-type approach after someone’s completed their chemotherapy, meaning we plan for about two years of treatment. And patients that can’t get chemotherapy for whatever reason we can use immunotherapy as a first-line treatment.  

And it’s also used in localized bladder cancer meaning cancer that’s contained only to the lining of the bladder in patients who’ve gotten treatments that go inside the bladder called BCG. When their cancer isn’t responding, immunotherapy is also an option there.  

Katherine Banwell:

And what might be some of those side effects that patients should look out for?  

Dr. Anari:

So, what I tell everyone is they can get inflammation or an “itis” of anything. So, some examples of that: If someone has a rash, that’s called dermatitis. That can be mild, or it can be severe. If someone has inflammation of the bowels or colitis, they can have diarrhea that starts all of a sudden.  

Another example is pneumonitis or inflammation of the lungs. People may have cough, trouble breathing, low oxygen levels. It really can affect any organ system that you have. So, that’s why it’s really important if something feels different to let your doctors know.   

It’s also really important if you’re not near your doctor for whatever reason and you end up seeing a local doctor, let’s say, at an emergency room that you let them know that you’ve received immunotherapy because they’ll think about the problems that you’re having a little bit differently.

Katherine Banwell:

What is targeted therapy, and how does it work to treat bladder cancer?  

Dr. Anari:

So, targeted therapy is really a newer, more tailored approach to treating certain types of bladder cancer. Targeted treatments because they’re targeted have most of their effect on the cancer cells. Although, obviously, there’s other potential side effects. But the way it works to treat bladder cancer really depends on the different types. There are several different targeted treatments out there.   

Often, targeted treatments are approved for people after they’ve gotten chemotherapy and/or immunotherapy for their bladder cancer treatments. There are several different ones out there. Erdafitinib is one of them. It’s a pill. It’s approved for patients who have an FGFR alteration.  

Well, what is that? It’s something that your doctor finds by getting the DNA or genetic makeup of your cancer cells. So, those pills are available to people with that certain alteration that’s found on special testing. 

With these pills, potential side effects – we talked about how the effects are mostly on the cancer cells. But there are other side effects that we have to keep in mind. This drug in particular can have different eye disorders. So, we work closely with ophthalmologists.  

And then we check blood work because people can have high phosphate levels in the blood. Phosphate levels can be controlled often with diet, sometimes with medications, and sometimes with just adjusting the dose of the pill itself.  

Katherine Banwell:

You mentioned the FGFR genetic alteration. Should bladder cancer patients undergo molecular testing?  

Dr. Anari:

So, the most common place where we do that is when people have metastatic bladder cancer. It’s a good idea to test the biopsy sample or bladder cancer sample that’s already been removed.  

That way we get this information. While it doesn’t always change the up-front treatment for bladder cancer, it is really important to know really what tools in our toolbox we have for the treatment of bladder cancer.

Lung Cancer Targeted Therapy: What Is It and Who Is It Right For?


Transcript:

Katherine Banwell:

What is molecular testing? 

Dr. Estelamari Rodriguez:

So, that is very critical for lung cancer patients today. So, molecular testing is when we get tumor cells, and we analyze the genetic changes that lead to that tumor growth. And that can be done today in different ways. The usual goal standard have been to do a biopsy of the tumor, and then do next generation sequencing when we analyze many, many genes that can impact cancer growth, and then we get a signature what drives that cancer. And in doing that, we discovered that some patients, for example, regardless of who they are, women or men, smokes or non-smokers, they may have a genetic driver that we have a treatment for, that does better than chemotherapy. 

So, that is important that you identify that as early as possible.  

Katherine Banwell:

Why is it necessary for patients to undergo molecular testing prior to a lung cancer treatment plan? 

Dr. Estelamari Rodriguez:

So, it is extremely critical because we have data today that several of these targeted treatments, the improvement of survival is not in the span of months, it’s in the span of years. 

People will do years better if they started with the treatment for their specific cancer driver mutation than if they received chemotherapy.  

We also saw that when immunotherapy came in the market a lot of patients, rightly so, doctors thought, “This is the best new thing, let’s put this patient on immunotherapy” and they were not testing patients for mutations before they started. And we found out two things, one is that there is toxicity if you give immunotherapy followed by some of the targeted therapies, specifically one called osimertinib (Tagrisso), so that you could cause harm.  

And then, number two, that immunotherapy doesn’t work in every case. A lot of patients with targeted driver mutations, they do better with a targeted treatment than they will do with chemotherapy and immunotherapy. So, I think it is important to define that early. We also now have approval for at least one targeted therapy after surgery. 

So, even patients that are early stage, which is not the majority of patients, but those patients also will get an improvement if they have an EGFR mutation specifically if they receive that targeted pill treatment after surgery. So, understanding the tumor is important so you can select the right treatment for the patient.  

Now, this is a dynamic thing, so tumors can evolve over time. So, there are many times that patients come to us for second opinions, and we actually recommend a repeat biopsy to understand the new genetic signature of that tumor because we may find a new option that was not there at the beginning.

Transcript:

Katherine Banwell:

Dr. Rodriguez, research advances aren’t possible without patients participating in clinical trials. 

So, where do clinical trials actually fit into a lung cancer treatment plan? 

Dr. Estelamari Rodriguez:

So, clinical trials are really what move the science of all these developments that we saw at the oncology conference, the ASCO conference.  

So, it’s not until patients join trials that we can approve drugs. So, I think clinical trials are very important, so we move the science. But then, for specific patients in lung cancer, now that we’re moving all of our best therapies upfront, we run out of options faster than we did for some patients. So, it is important that A) that we have access to clinical trials, which if we look across the country many of our cancer patients don’t have either Phase I programs near them, they’re very difficult to get to, or very expensive to get to. 

So, we have to do a lot in terms of increasing access to clinical trials. 

But I think your specific question has to do where it comes in. I think if you have advanced lung cancer, where most patients today will not have a cure, clinical trials is at the center of things that should be considered from the get-go. Sometimes some of the drugs are what is called Phase I, that these are new drugs that we’re trying to find a dose, we don’t really understand the efficacy of the drugs. So, those trials are reserved for patients that have failed standard treatment. 

But then we have patients with very difficult situations that are progressing really fast that should join clinical trials. And I think that as we do more biomarker testing, we are learning a lot about the individual patient tumor.  

So, the promise of precision medicine is that you can actually find drugs for specific patients, and that’s what clinical trials that are called basket trials, where if you have a mutation regardless of your tissue of origin. So, for example, we have two large basket trials that we are enrolling patients, one called the TAPUR trial and the other one called MATCH.  

And MATCH is organized by the NCI and TAPUR by ASCO, and these trials if you find you have a biomarker analysis of next generation sequence, you find a specific mutation, you can actually see there’s a trial for this specific patient. So, the trials come in, I think they’re very critical to move the science, they’re very important for individual patients with rare mutations, but I think it’s upon us to make sure that these trials are available.   

Katherine Banwell:

What advice do you have for patients who may be hesitant to participate in a clinical trial? 

Dr. Estelamari Rodriguez:

So, I think you have to ask questions, I think that there’s a lot of misconceptions in different communities. So, we take care of a lot of Hispanic patients, and we have kind of really have to do a lot of education about what patients and patients family’s think about. Because sometimes I feel I have to convince the family members before I can get to really talk to the patient about the trials. 

But I think in the past, trials have been considered only experimental, and patients are used for science but not really getting a benefit. So, I think that’s the first misconception. When we open a trial at our cancer center, and I’m part of the experimental therapeutics’ unit, we are opening trials that we believe that that science will move and offer something in addition. So, I think, that is not because we want to do an experiment, it’s because we really want to offer this patient the latest, or something new, that could potentially offer them a better response than what we are achieving with our standard treatments. 

So, I think that’s the first misconception, that these are experiments on patients and patients don’t benefit. The whole point of the trial is to find better drugs and benefit.  

So, it’s been shown in multiple parts of the country and big cancer centers that patients that join clinical trials do better at the stage of their disease. And part of the reason that they do better is that instead of having one doctor that is making decisions, and they’re running out of options, and kind of coming up with ideas out of nowhere, when you join a Phase I clinical trial or an organized trial, you have at least 10 to 20 doctors that are looking at your case or reviewing your images. There’s a lot of check to make sure that you’re not getting unwanted toxicity and that the trial is stopped if you’re not getting a benefit. 

And this is important so that we don’t expose more patients to toxicity, but that’s another misconception that it’s not safe. And we’ll do our best to make sure that it’s safe.

Immunotherapy for Lung Cancer Treatment: What to Expect


Transcript:

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.

Shared-Decision Making Your Role in Lung Cancer Treatment Choices


Transcript:

 Katherine Banwell:

Why should lung cancer patients ask their doctor about biomarker testing?

Dr. Patel:

It’s extremely important. Biomarker testing is really the guiding principles by which we make a treatment plan for lung cancer patients in 2021.

We know that every patient’s lung cancer is a little bit different at the molecular level. So, they might look the same under the microscope, but, you know, if we get to a more deeper level, we can understand that they are quite different and they may respond differently to different treatments.

And so, it’s extremely important. And I think it’s important to know that nationwide we don’t always do a great job of doing real adequate biomarker testing. And so, from a patient perspective, it’s really useful to be an advocate for yourself and to ask your physician, you know, “Have we done biomarker testing, and to what extent have we done biomarker testing?” because it’s not uniform across the country at the moment.

Katherine Banwell:

Are there specific biomarkers that affect treatment choices?

Dr. Patel:

Absolutely there are. So, as an example, the molecular testing with DNA mutation analysis – so we actually look at the mutations that are present within a patient’s tumor, and that really does define a group of patients both in the curative setting and in the setting with more advanced disease that defines our treatment choices. Likewise, PD-L1 is a biomarker now that is being incorporated onto whether or not we use immunotherapy or whether we use immunotherapy with chemotherapy for patients that don’t have mutations.

So, it’s become an extremely important part of our treatment regimen.

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.

What about biomarker testing results?

Dr. Nastoupil:

So, in a perfect world, we would be able to take a patient’s specific tumor, sequence it, and provide a recipe or a solution to solve the problem. And that’s what a biomarker is.

It’s something that’s unique to the patient’s given tumor that then would inform what is the best treatment. So, we’re lacking in some ways a perfect scenario. What we do have, as what I’ve mentioned, some molecular studies where we can look for specific genes or rearrangements in the genes that may help us predict the future.

And in diffuse large B-cell lymphoma, one of the most common examples of this is what we call double hit where we’re looking for two genes – MYC, which is M-Y-C, and either BCL-2 or BCL-6. These are genes that we all have. It’s just the lymphoma has moved these genes into sort of more of a prime real estate location that makes it a little bit more resistant to standard treatments.

So, if you move those genes in that tumor DNA, we call that our rearrangement. And we pick that up based off a FISH study. And if both of those features or all three of those features are there, we call it a double or triple hit.

That’s a potential biomarker that may suggest that particularly R-CHOP or standard treatment may not be the best strategy. There’s some limitations to that conclusion in that that’s not true for every patient. For about 20 percent to 30 percent of patients with double hit features, they’re going to do really well with R-CHOP.

So, that’s why we are lacking in how effective these biomarkers are. And it would be great if we had additional biomarkers that were more precise or could tell us more than just that the standard may not be optimal.

So, that’s where we’re spending a great deal of time and effort in our research efforts just trying to identify biomarkers that may tell us what’s the best approach for a given patient or what we like to call personalized medicine.

How Do Genetic Mutations Impact Breast Cancer Risk, Prognosis and Treatment?


Transcript:

Katherine:

Many patients are confused by genetic testing. Let’s look at the difference between germline and somatic testing.

Dr. Sammons:

Yes, that’s a really good question and one that comes up in the clinic quite frequently. When I tell a patient that I want to get some sort of genetic testing, they often are confused, and say, “Well, I’ve already had genetic testing, maybe when I was first diagnosed with early-stage breast cancer.” And so then, I do often times need to explain what the difference between germline and somatic genetic testing is.

So, germline testing is testing that’s done on cells in your body that actually don’t have cancer. And the purpose of germline testing, which we often do in early-state breast cancer or in metastatic breast cancer, is to understand if you have inherited genes that could pre-dispose you to developing breast cancer. But also, in the metastatic setting, it’s important to do germline testing because we do have drugs that are approved for patients that have germline mutations in the BRCA genes. And research is evolving, but there are other germline genes of interest that could be biomarkers for other therapies.

Somatic testing is basically genetic testing on the breast cancer cells themselves. So, most often we will get a biopsy, usually of a metastatic area, like the liver, or bone, or lung. Really the safest, most accessible place. If we’re able to safely get a biopsy, oftentimes we’ll send somatic testing – that’s also referred to as usually next generation sequencing – is all somatic testing. And that tests mutations that have developed in the breast cancer itself. It could potentially be biomarkers for optimizing and tailoring personalized treatment approaches to the patient’s cancer.

Katherine:

I’d like to define a few terms. First of all, what is biomarker testing?

Dr. Sammons:

That’s a really good question. So, a biomarker is really anything – it could be a gene; it could be a protein – that is expressed on a patient’s cancer, that makes them a good candidate for a certain drug, essentially.

So, one of the earliest biomarkers that we’ve had in breast cancer – and still, I would argue, the most important biomarkers – are estrogen receptor and HER2.

Now, we test all breast cancers for estrogen receptor and HER2 because we know for estrogen receptor – if a patient has estrogen receptor high positivity at their initial diagnosis, that is the best biomarker for endocrine therapies, whereas HER2 present on a breast cancer cell – patients that overexpress HER2, they are great candidates for drugs that specifically target HER2.

So, it simply means that we found something on their breast cancer cell that makes them a good candidate for a treatment.

What is a genetic mutation?

Dr. Sammons:

So, genetic mutations are a permanent change in the DNA of a gene, in either a cancer cell or a cell that somebody was born with. So, it’s a change in the DNA sequence. And some gene mutations drive cancers to grow. Some mutations do not drive cancers to grow. Generally, in the treatment of all advanced cancers, we only target with drugs those gene mutations that we know are what we call “driver mutations.” So, mutations that actually cause the cancer to grow.
