Katherine:

Welcome to Insist! Lung Cancer, a program focused on empowering patients to insist on better care. Today, we’ll discuss the latest advances in lung cancer, including the role of genetic testing and how this may affect treatment options.

I’m Katherine Banwell, your host for today’s program. Joining me is Dr. Tejas Patil. Dr. Patil, would you introduce yourself please?

Dr. Patil:                     

Sure. Thank you for inviting me to speak on this platform. My name is Dr. Tejas Patil. I am an Assistant Professor at the University of Colorado, where I take care of patients diagnosed with thoracic cancers, which include non-small cell lung cancer, small cell lung cancer, and also include mesothelioma and thymic cancers. My main research focus is on molecular alterations in lung cancer and development of targeted therapies.

Katherine:                  

Thank you. Before we start, a reminder that this program is not a substitute for seeking medical advice. Please refer to your own healthcare team.

Dr Patil, before we get into an in-depth discussion on lung cancer, would you tell us about the types of lung cancer?

Dr. Patil:                     

Absolutely. Lung cancer has a bit of a confusing nomenclature. Historically, Lung cancer was divided into small cell lung cancer and non-small cell lung cancer, and this distinction was based on how the lung cancer appeared under a microscope, but it also has practical implications. Small cell lung cancer tends to have a very different biology than non-small cell lung cancer. It originates from neuroendocrine cells and is treated very differently than non-small cell lung cancer.

Non-small cell lung cancer is also a bit of a misleading term because it really is a catch-all term. It represents a wide group of histologies that are not small cell lung cancer. So, basically, anything that isn’t small cell lung cancer will be non-small cell lung cancer, but that group is very heterogenous and includes subtypes like adenocarcinoma, squamous cell carcinoma, adenosquamous, large cell and even sarcoma type variance.

Distinguishing between the two is important because the prognosis and treatment options are actually very different between small cell and non-small cell lung cancer.

Katherine:                  

Well, let’s talk about testing and diagnosis. Following a diagnosis, are there specific tests that patients should ask their doctor for?

Dr.  Patil:                    

Right. After a diagnosis of lung cancer has been made, the most important next step is to establish a cancer stage, and so this is typically done through the TNM staging criteria. The T typically reflects the size of the tumor. The N reflects whether there’s lymph nodes involved with cancer and the M refers to whether there’s a metastasis, and metastasis refers to whether the cancer has spread outside of the lung.

Based on a combination of scores using the TNM criteria, lung cancers are staged from one to four. Now, to establish these different scores, oncologists will typically request varieties of scans. These include CT scans, PET CT scans, MRI and in some cases, very sophisticated ultrasound techniques called endobronchial ultrasound, so that’s the staging component. I think, in addition to the staging component, once a patient has a diagnosis of lung cancer, the tissue itself can be subject to a variety of different molecular tests which we will cover in this talk.

Katherine:                  

Well, let’s get into the tests. How are each of these tests administered?

Dr. Patil:                     

Well, first let’s discuss imaging.

Staging is a very important component of lung cancer, and at minimum, a patient should have a CT scan of the chest and abdomen with extension down to the adrenal glands. The reason for this is that this type of imaging, at least the extent of the imaging, will cover most of the metastatic sites that lung cancer tends to go towards. Additionally, a PET CT scan can be obtained.

Now, a PET scan is a very unique form of imaging. Patients will receive a radio labeled form of glucose and the principle of a PET scan is that since cancers metabolize glucose, which is sugar at a higher rate than normal tissue, the scan in principle helps clinicians identify spots where cancer could be. One important point about imaging and this is something patients should be aware of, is that lung cancers are unique cancers in that there’s a very high risk of spread to the brain.

And so, as part of baseline staging, almost every patient with lung cancer should be getting an MRI of the brain to rule out brain metastases.

Then a final point I’ll make is that patients with Stage 2 or 3 lung cancer really should have their cases reviewed in a multi-disciplinary context where there’s input from surgeons, pulmonologists, medical oncologists, and radiation specialists because the treatment for Stage 2 and 3 lung cancer can be quite complicated. I think, and we’ll talk about the – so, that was the staging part. Now, we can talk a little bit more about the diagnostic testing and molecular testing specifically.                    

There’s been tremendous advances in lung cancer. One of the biggest advances has been the appreciation that there are very specific mutations that actually “drive” cancers that cause them to grow, divide and metastasize.

We call this mutation an oncogene. Over the past two decades, there have been many oncogenes in lung cancer that have been identified. Interestingly several of these oncogenes, such as the ALK mutation, or the EGFR mutation, tend to occur in patients who were never smokers.

So, while smoking is the major environmental risk factor for lung cancer, our understanding of these, through molecular testing has identified a group of patients who were never smokers yet still developed lung cancer. The reason this is important to know is that there’s a variety of targeted therapies available for patients who do have mutations such as ALK or EGFR, and these are typically associated with very favorable outcomes in lung cancer.

Katherine:                  

What are common lung cancer mutations, first of all?

Dr. Patil:                     

There are many mutations that are found in lung cancer. I should mention that the scope of what mutations we find very much depends on the type of molecular test that’s performed. This is a topic that’s beyond the scope of this discussion, but know that when you say you are getting genetic testing, a lot of that depends on the genes that are in the test, meaning if a molecular test is only looking for 10 genes, or 10 mutations, it’s only going to pick up 10 mutations versus more comprehensive molecular testing, which look at hundreds or even thousands of genes, will identify more mutations.

That being said, there are approximately 10 mutations currently for which there are targeted therapies, either that are commercially licensed through the FDA, or are being evaluated in the context of the clinical trial.

And in patients who are heavy smokers, the most common mutation that we see that’s an oncogene is a KRAS mutation, and there’s currently drugs in clinical trials that are looking to target a very specific KRAS mutation. 

Dr. Patil:                     

In never smokers, the mutation spectrum is actually quite a bit more varied, and here, we see mutations such as ALK, EGFR, ROS1, RET, MET, HER2 and BRAF.

I want to make a quick point that there’s another biomarker that we use in lung cancer that’s not technically a mutation, per se, but it’s very important for clinicians to obtain, and that’s called a PD-L1 score. This is a score that helps clinicians decide how effective immunotherapy can be in a certain patient.

Katherine:                  

Are some mutations more common than others?

Dr. Patil:                     

Yes. I mean, there are mutations that are very common. I think to answer that question a little bit more in this cleanly, I would say that there are some mutations that are very common in lung cancer such as TP53, but these are mutations where we can’t actually, we don’t have a targeted approach to manage them. So, when I refer to common mutations, I’m talking about mutations where I either have a drug that is available and able to target the mutation, and this drug is being either investigated in a clinical trial, or is commercially licensed.

In lung cancer, the most common oncogene would be KRAS, and there, there’s a couple of exciting clinical trials where there are some promising drugs in development for treating this specific mutation which has been very challenging to treat in lung cancer.

Katherine:                  

How is genetic testing for lung cancer different from hereditary genetic testing?

Dr. Patil:                     

That’s a great question. We have learned that there are several cancers, such as breast and colorectal cancer, where there’s clear evidence that there are hereditary genes that increase an individual’s risk for developing cancer. I personally prefer the term molecular testing over genetic testing as this emphasizes that we’re looking for specific mutations that are really acquired during a patient’s lifetime and typically not inherited.

Katherine:                  

How do genetic mutations in lung cancer affect treatment options for patients?

Dr. Patil:                     

Well, the finding of a molecular alteration, or an oncogene, is really important for a patient with lung cancer because it offers a unique class of therapy that the patient would not have had otherwise. Finding a mutation is important because it allows patients to have treatment options outside of traditional chemotherapy or immunotherapy.

Katherine:                  

Dr. Patil, how do targeted therapies work?

Dr. Patil:                     

Targeted therapies are interesting. They work by specifically targeting and blocking specific mutations in lung cancer, and so it’s kind of like a lock and key model. By blocking the binding site of a mutation, the treatment actually prevents that cancer cell from properly functioning, and this in turn causes the cancer cell to be unable to divide, unable to grow, and ultimately results in cancer cell death. Targeted therapies typically come in either a form of a pill.

That’s the most common way that patients take targeted therapies.

As an aside, I will note that there’s a very unique class of targeted therapies called antibody-drug conjugates. These are really fascinating molecules. They are treatments that are consistent, but very complex, bioengineered structures, so what you have is an antibody that targets some protein on the surface of a cancer cell, a mutation.

This antibody is linked to a chemotherapy payload, and so it allows for very potent chemotherapy to be delivered effectively and selectively to cancer cells, sort of like a Trojan Horse effect where the antibody finds the cancer cell, goes inside the cancer cell, and once the whole structure is inside the cell, that’s when the chemotherapy is released.

Therefore, it’s a way of giving chemotherapy in a more targeted way, and there are several of these in clinical trials right now.

Katherine:                  

Well, you mentioned patients taking pills. What other treatment regimens are there for the targeted therapies?

Dr. Patil:                     

For targeted therapies, the most common is a pill. The schedule depends on the mutation, so it can sometimes be once a day or twice a day. And then, there are IV treatments that we see, and that is the antibody drug conjugate that I’m referring to where patients will have to go to a infusion center to get those. But to my knowledge, most of those are still in the context of a clinical trial, and so I think it’ll be a while before we start seeing them commercially licensed.

Katherine:                  

How do the newer therapies differ from the more traditional chemotherapy?

Dr. Patil:                     

Chemotherapy is still an important tool in an oncologist’s arsenal.

It works by killing, or rather it works by affecting a cancer cell’s ability to divide and grow. The logic here is that since cancer cells typically grow faster than normal cells, chemotherapy is more likely to kill cancer cells. It should be noted that while that is true, there are certain cells in the human body that grow very quickly as well, such as hair follicles, the lining of the mouth, and cells within the bone marrow. And so, as a result, it’s very common that the side effects of chemotherapy typically affect these cells, so you typically see hair loss. You see mucositis, or inflammation of the mouth, diarrhea, and low blood counts, and this a general side effect of chemotherapy.

Katherine:                  

Are there common side effects for some of the newer therapies as well?

Dr.  Patil:                    

That’s a great question and the way I’m going to answer that is it depends on the mutation that the targeted therapy’s affecting. So, a mutation that I’m going to use as an example is a mutation called EGFR. Now, this is a mutation that we see in lung cancer that causes cancer cells to grow, divide, and metastasize.

But EGFR is interesting because it also is found in normal cells, and specifically it’s found in the cells of the skin and the gut lining. This is an example where you’re giving a very targeted therapy that’s trying to attack just the cancer cell, but because normal skin cells and gut cells have this EGFR receptor, the side effects there tend to be rash and diarrhea. Now, that’s unique to EGFR. There are other drugs such as the ALK mutation or the ROS1 mutation that do not have this side effect because that specific receptor is not found in the human body.

Katherine:                  

Oh, I see. Well, how is the effectiveness of treatment monitored?

Dr. Patil:                     

Typically, I have the philosophy that patients generally know their body and can tell when symptoms are getting better or worse. So, as a guiding principle, I rely on patient input very heavily. That being said, I corroborate that experience with some testing. In my practice, I frequently use what we call serum tumor markers, so these are very nonspecific-like tests that sort of let us know if there’s cancer type proteins in the blood that we can detect while they are on targeted therapy.

And then additionally I would recommend that patients get scans frequently, at the minimum every three months if they are on targeted therapy and doing otherwise well. That includes a CT scan of the chest and abdomen, and in certain cases, an MRI of the brain, if there were brain metastases before.

Katherine:                  

Is it necessary to retest at any time?

Dr. Patil:                     

This is a good question and it’s an evolving question. In general, I strongly advocate that patients who are on targeted therapies obtain additional molecular testing after they’ve progressed, and the reason is the following. Cancer cells evolve resistance mechanisms to overcome targeted therapies and understanding these resistance mechanisms can be quite helpful in designing next lines of treatments.

A very good example of this is in EGFR lung cancer. The very first type of targeted therapy for EGFR positive lung cancer was a drug called Erlotinib. What we had seen was that when patients were on this drug, Erlotinib, they would respond, and they would do really well for a period of time.

But after a period of time, patients would progress on this therapy, and a very common mutation that we would find, once they progressed was a mutation called T790M. By biopsying this patient and finding this mutation, it was very helpful because it allowed the medical community and researchers to investigate a new drug called Osimertinib, which can overcome that resistance mutation.

And we’re learning a lot about resistance pathways and resistance mutations in lung cancer, so I think it’s very important that patients who are on targeted therapies specifically get retested and re-biopsied.

Katherine:

Let’s move on then. Dr. Patil, what are you excited about in lung cancer research right now?

Dr. Patil:                     

I thought ASCO 2020 this year was a very exciting cancer conference, and I’m very excited about where lung cancer research is going. I think there are two areas to be very hopeful about.

First, is that there have been several oncogenes or mutations that we had known about for a very long time, but there was just no targeted therapy available. I think in the next several years, you’re going to start to see more and more targeted therapies available for patients who have otherwise rare mutations.

And examples of this would include KRAS G12C, RET, Met and HER2, so this is very exciting because these were mutations that we had known about for a long time, but just until more recently really haven’t had any successful therapy for.

The other area that’s very exciting is that we’re starting to see the use of targeted therapy and immunotherapy in patients who have earlier stage cancer. So, there was a lot of talk this ASCO about using targeted therapies in patients who have, for example, Stage 3 lung cancer, and is there a benefit in doing that? I think that’s going to be a very interesting development of patients who have Stage 1 to 3, which we typically treat with curative intent, how do we make sure that they improve their outcomes and really stay cured?

Katherine:                  

Right. What would you say to patients who are nervous about participating in a clinical trial?

Dr. Patil:                     

That’s a great question. I really appreciate you asking that. In general, I would highly recommend patients consider clinical trials. I think there’s a couple of things to point out. It’s very important to remember that clinical trials are evaluating novel therapies as compared to current standard best practice. So, placebos are rarely used in cancer research unless there’s no known effective therapy. It’s important to remember, it’s not ethical to have someone take placebo if there’s known treatment that work, so when a patient enrolls in a clinical trial, sometimes they don’t know which treatment they’re getting, but at least they will know that whatever treatment they’re getting is the best current standard of care.

I want to also point out that clinical trials really answer, in my mind, two important questions. The first question is, is the new treatment safe? And does the new treatment work better than current standard of care? These are really important questions for advancing the field, especially in cancer research. Clinical trials are a small part of the research. I mean, when a drug that’s getting introduced into a clinical trial, it’s sometimes helpful to think about all the investment that has gone in before them. The drug has to be discovered, created.

It has to be purified, tested in animal studies, before it ever reaches human studies. And so, there’s only the most promising agents are actually ever introduced at clinical trials, and there’s a lot of data to show that the biggest barrier for completing clinical trials, and therefore understanding which treatments are effective, is really participant enrollment.

I think there was a recent study that showed that about, I think less than five percent of patients, less than 1 in 20, with cancer will ever take part in a clinical trial, Therefore, if a patient has that opportunity, I would strongly encourage them to consider it.  

Katherine:                  

Do you think a second opinion is necessary? Would you encourage patients to consult with another specialist?

Dr. Patil:                     

In general, I’m a big advocate that patients should get all the information they need to make informed treatment decisions, and if that involves getting second opinions, I welcome that.

 I think that a knowledgeable patient is an empowered patient, and certainly a knowledgeable patient is one that I think will be able to guide themselves through a very complex medical journey. So, in general my philosophy is I’m always encouraging of second opinions if the patient feels that they need more information to make a best decision.    

Katherine:                  

What advice do you have for patients who may be hesitant to speak up and advocate for themselves when it comes to their care and treatment?

Dr. Patil:                     

Great question. In general, I’m a big believer that an empowered patient is a patient that can make really good medical decisions as they navigate their own medical journey. Ultimately, it’s important for patients to be knowledgeable and seek multiple opinions. Really get the best advice, so that they make the best decisions. Oncology is a very complicated field. The treatment options can be very nuanced.

Therefore, it’s important to know that when a decision is presented to a patient, that it is a decision that is made with the knowledge of what is the best standard of care. But if the patient doesn’t feel like they have the most informed data to guide their own medical decision making, then it’s really important for them to advocate for themselves.

To that point, especially for some of these rarer mutations, there are many social media patient advocacy groups that are very, very, very well organized, very effective, and have a list of really useful questions. Some examples of that are the ALK Positives and the EGFR Resisters.

Katherine:                  

Okay. I would be remiss if we didn’t discuss COVID-19 to some extent. What should lung cancer patients be considering at this time?

Dr. Patil:                     

This is also a very important and timely question. lung cancer patients are certainly at very high risk of complications from COVID-19. And it’s understandable, especially given the kinds of treatments that patients with lung cancer receive, that there’s a lot of them will wind up having compromised immunity which makes them at increased risk for adverse outcomes from COVID-19. That being said, I think it’s really important that this be balanced with the actual risk of untreated or inadequately treated lung cancer, which is also a major medical concern. What I tell patients is that, at least at our institution, we do everything we can to create an environment that is as safe as possible from a COVID mitigation standpoint.

But at the end of the day, untreated lung cancer can have a very aggressive course, and so making sure that patients understand that as we try to move things to a more telemedicine type approach, that there are some things where you really just have to come and see your doctor. Not everything can be done virtually.

Katherine:                  

Right, and my next question was is telemedicine the best approach right now?

Dr. Patil:                     

Well, that’s also, I’m going to answer that in a somewhat frustrating way, which is that there’s – yes and no. I think telemedicine is helpful for patients who have very stable disease and are on anti-cancer treatment, so specifically a patient on targeted therapy, for example.

A pill once a day. Their last scans show that they’re doing really well. They feel well. They’re exercising every day. That patient, probably we can do a visit virtually and just make sure and check in that there’s nothing new or concerning that’s come up.

The other patient that probably I can see a role for telemedicine is someone who had, let’s say, a Stage 1 lung cancer that was treated with surgery, and we’re just monitoring them on surveillance. That patient probably doesn’t have to come into the clinic to see us. But in general, the thing about lung cancer is that most patients are getting some kind of chemotherapy or immunotherapy and will be coming into an infusion center, and so what I would tell patients is if there’s any new or concerning symptoms, to a very low threshold for seeking an in-person evaluation.

Katherine:                  

As a researcher in this field, Dr. Patil, what do you want to leave the audience with? Are you hopeful?

Dr. Patil:                     

I’m very hopeful. I think, it’s kind of amazing when I look at the history of lung cancer and where the field was in the 2000s, now that we’re in 2020, and what remarkable advances have been made in 20 years. It’s worth reminding patients that in 2000, there was, platinum chemotherapy was the first line for metastatic lung cancer, and then there was a second line chemotherapy and that was basically it. Now we’re in an era where we have extensive molecular testing of lung cancer. We’re identifying new mutations that can be targeted with very sophisticated pill-based therapies. We have immunotherapy. We’re learning about how these combine with each other to produce the most optimal outcomes, so I think in 20 years a lot has been achieved, and I’m really excited to see where we go from here.

Katherine:

Hello, and welcome. I’m Katherine Banwell, your host for you today’s program. Today, we’re going to discuss how to access the most personalized lung cancer therapy for your individual disease and why patients should insist on essential testing. 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.

Let’s meet our guest today. Joining me is Dr. Heather Wakelee. Dr. Wakelee, would you please introduce yourself?

Dr. Wakelee:              

Sure. Thank you so much and I’m really delighted to be on this and get to address all of our listeners. So, I am Dr. Heather Wakelee and I am a lung cancer specialist. I work at Stanford University where I’m also the chief of the Division of Medical Oncology.

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?

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:                  

Well, I imagine that much of personalized immunotherapy for a patient requires a number of tests and then a thorough review of the results. So, 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 can not 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:                  

Well, let’s go a little deeper. And, you did mention some of this already, 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.

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.

Lung Cancer: Gina’s Clinical Trial Profile from Patient Empowerment Network on Vimeo.

Lung cancer survivor Gina was shocked after receiving her diagnosis at age 38. Watch as she shares her lung cancer journey including her diagnosis, treatment, clinical trial experience, and advice to other patients. In Gina’s words, “So what I’ve learned is that clinical trials are really the best and newest care for patients, and I feel like all patients should have access and have the experience of a clinical trial.”

Patient-to-Patient Diverse Lung Cancer Clinical Trial Profiles

Transcript:

Gina:

My lung cancer story is probably not that unique. There are actually a lot of people that are just like me. I was 38 years old, a nurse at the peak of my physical health, and I was actually training for a triathlon. And I just developed a cough, and no one would take me seriously. As a nurse, I felt like something was wrong because I was losing weight, and I wasn’t trying, and eventually I had to self-pay for a chest X-ray, and the chest X-ray showed that I had something going on in my left lung, but they weren’t really sure what it was. So, I took that chest X-ray to the emergency room for exactly what they tell you not to — a cough, and thankfully, the ER doctor took me very seriously and finally that led to a stage IV incurable, inoperable lung cancer diagnosis. As a nurse, I knew the severity of, of the diagnosis, and I knew that also there was a possibility for some new drugs, and so I’m so thankful that my doctor in Memphis knew to do biomarker testing, he found out that I was ALK-positive (anaplastic lymphoma kinase). My very first thing that had to happen was I had brain surgery.

And I feel like I’m a very lucky girl to have survived all that I have, and I watched the pain in my husband’s eyes as I rolled back from brain surgery and the f as I woke up from that brain surgery. And then the next thing was my left lung was removed, and I remember seeing my two boys and as I rolled back, how they were afraid for me to lose my lung, something that they felt like I needed. And so again, we experienced so much joy as I came back from that lung surgery and eventually recovered, and then I remember the first day that I actually was able to run a mile again, and that was so incredibly exciting for me. So now I was diagnosed in 2015, and now it’s 2021 and through the years, I went through each targeted therapy and cancer outsmarted it, and so the targeted therapy failed me eventually. And each one lasted about a year or so, and I think that through these years, I kept thinking that science would keep up with me, and I kept riding that wave of science and research, and I was so thankful. But we knew that it was incredibly important to continue to fund research for lung cancer, because when it comes to lung cancer, it seems like even though it’s the number one cancer killer of men and women and anyone with lungs can get it. The funding for it is so low because there’s still a thought process that smoking is the cause of lung cancer, and while we know that there’s a lot of people that are just like me who have absolutely no risk factors, we know that research is incredibly important for this disease. So, fundraising for lung cancer research and through our group, ALKpositive.org was incredibly important for me.

I just kept hoping that the next thing would happen, but I finally ran out of the last targeted therapy, and so that’s when I started looking for a clinical trial. And right now, it’s not that easy to find a clinical trial. Within our group, we have some amazing volunteers and members who really work to put the clinical trials out there for ALK-positive patients and to make sure that we know that we’re aware of them. And so anyway, I had a great friend who helped me look through the clinical trials, and eventually I found the perfect clinical trial for me. But it required me to travel to Boston, Boston quite a bit, and so that was really difficult raising two young boys and having my husband, who is also working, not be available. It was just really not fitting with our family to be able to travel and be away from my family so much, so I kept looking for clinical trials, and I finally found one that was about 200 miles away. And it still requires me to leave my family about every two weeks or so, sometimes just for a blood draw, but I’m so incredibly encouraged, because we found out that the clinical trial of this combination drug is working, and we found that cancer though it had kind of spread everywhere in my body, in my brain and in my pancreas, and even around my pulmonary artery, all of the cancer had decreased by about 50 percent. So, I’m incredibly encouraged, and that’s where we are now in the journey, and we’re just going to hope that the clinical trial keeps working and that new options are coming down the pipeline for other lung cancer patients.

A clinical trial is something that has, my perception has completely changed about. I thought when I was first diagnosed, a clinical trial was kind of like being a guinea pig, and now I think that it’s more like being a pampered poodle. So, what I’ve learned is that clinical trials are really the best and newest care for patients, and I feel like all patients should have access and have the experience of a clinical trial. We know that sometimes clinical trials don’t always pan out to have the best thing, but I see over and over again that clinical trials for patients have a lot of science behind them, and it’s an opportunity for patients to try the latest and greatest.

If you’re considering a clinical trial as an option, the most important thing is for you to become informed, really make sure you understand some clinical trial, really understand what the expectations are of you, and make sure that you’re willing to do what’s required of the clinical trial, make sure, that also that it’s conducive to your lifestyle and to your family. I think those are the things that are the most important. A clinical trial is an opportunity for the latest and greatest, but you also have to make sure that you understand what’s required and make sure that you are okay with the requirements of the trial.

If I were to tell you how I’m feeling today, I would tell you that I’m feeling encouraged that I have so much hope for the future. Being a part of a clinical trial has…honestly, if I’m very, very truthful, it was scary at first. In fact, I even cried when I signed the clinical…the clinical trial consents. It was completely scary, but now that I’ve been into the clinical trial now about nine weeks, my last scans were really good and really promising, and so for me, I feel very, very hopeful for the future, and I’m hoping that this is a drug combination that can be brought to other patients and that they can all benefit from this clinical trial and from my experience.

Lung cancer patient Donna had a sub-optimal experience with her first treatment regimen. Watch as she shares her lung cancer journey, knowledge and benefits gained from a clinical trial, and her advice to patients seeking additional treatment options.

Patient-to-Patient Diverse Lung Cancer Clinical Trial Profiles

Transcript:

Donna: 

I’m Donna, I am 68 years old, and I was diagnosed with lung cancer in 2012. 

When I was first diagnosed with lung cancer, I was put on a regimen of paraplatin (Carboplatin) and bevacizumab (Avastin) drugs. I received that for four or five months and did not do particularly well on it.  My body did not react well to those chemicals, my tumors, however, did respond as long as I was getting the drug. 

After we discovered that my tumors were not going to respond to chemo unless I was getting it all the time, my doctor suggested that I either go on another drug, chemo drug that was even harsher than what I had been on and did not have as good of results or suggested that I might do a clinical trial. I had been told that I probably only had about four months to live. And I decided that, number one, I was in no hurry to be sicker than I already was and number two, that if there was a way I could help future patients by participating in a trial that the trial was the way I wanted to go. I never ever assumed that I would benefit from being in a clinical trial, I was very uninformed about clinical trials. 

A clinical trial is a way that the pharmaceutical company or researchers test certain drugs. They will see if the drug works at all, it moves to humans and out of the laboratory, and everything doesn’t necessarily work the same way or on humans as it did in the lab. So…in the Phase III trial like I was in, by that point in time, they’re learning how in the fairly general population, how the drug is going to react, if it’s actually going to work, how much of a dose is the right dose, and how frequent it should be. The clinical trial is just to provide the information that’s needed to determine whether a drug should go forward into the general population or not.  

One tumor started growing again, and I chose to have radiation, which made me have to get out of the clinical trial. But after radiation, I went back onto the same drug that we had been testing through the clinical trial, because I had responded so well through it, and I stayed on that drug until from 2013 until 2019. And during in April of 2019, I quit having any kind of treatments, and so now I’m just monitored every four months to make sure that my tumors have remained stable and so far, so good. 

I would go into a clinical trial without hesitation if my tumors begin to grow again, my first consideration will be to get into another clinical trial, you are getting the cutting-edge drug. And not only that, while I was in the clinical trial, I had a researcher and I had my oncologist, I had a lot of people really following my health. I had multiple, far more scans done, which some people might look at as a negative, but they were really following me closely to make sure that my response was what it needed to be. You can get out of the clinical trial, you are not stuck in a clinical trial. So, if you get into it and you are either sick or if your tumors are not responding the way you hope they would, you’re not stuck in a clinical trial, and that’s an important thing to know. To me, there will never be another option that I will consider first, I will always consider the clinical trial first. And because I felt that the quality of care I got was higher, and it also saves you a lot of money because at least the drug itself is going to be provided at no cost. 

So that’s a huge consideration too. 

I would not be afraid to look into clinical trials, I would never accept a doctor telling me that there were no options for me. I have friends who had doctors tell them that they just didn’t think there was anything more that could be done, they needed to go into hospice. My advice is to look for a different doctor, because that’s not always true. And clinical trials are not necessarily easy to find, but I would certainly do my due diligence and look into whether there is one that’s good for you. And I would also strongly recommend that you immediately go through genetic testing so that you know what kind of mutations you might have, because that will drive the kind of clinical trial you might be wanting to get into, and also just the treatment in general.

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.

Transcript:

 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.

Dr. Nicole Rochester: 

If we shift gears a little bit and talk about access and some of the concerns about treatment access for lung cancer patients, we know that sometimes these barriers that patients face actually limit their access to treatments, and you indicated surgery as being the mainstay and some difficulties with that, so how can we empower patients so that they don’t feel limited in their care, and how do we make them aware of these treatment options that are available, so that if they are in an office and maybe something’s being offered, but that’s not actually, the standard of care, how do we empower them to get that information and then to act on it? 

Dr. Olugbenga Okusanya: 

Yeah, so number one, which is something I think people do and they don’t realize how valuable it is, bring a friend to the appointment, don’t come by yourself, because you are in an incredibly vulnerable position, you’ve learned or are learning something incredibly emotionally charged and usually very scary. So, you want to bring someone who obviously is going to love you and care about you, but has enough emotional distance from it that they can be your advocate, they can ask those questions in the room that you may just not be there mentally to ask. Number two, never be afraid to get a second opinion, if you’re lucky enough to live in a populous area with multiple health systems, get a copy of your chart, get a copy of your data, get your disc, make an appointment to see another specialist in another health system and see what they say. Because at the very least, if the information is concordant, then you’re going to feel pretty good about saying, “Okay, then I should just go where I think I feel best or who I have the best sort of relationship with?” And again, if you are not lucky enough to have that opportunity, I would be very aggressive about seeing if telehealth is an option to reach out to someone who is a specialist, I’ve had not happened to me in the past, I remember I had a woman who telehealth, me from Ohio, because she’d actually read one of my papers about lung cancer, and she sent her scans, uploaded them, I looked at them and I gave her my opinion, and this is the new age or medicine. 

This is where we’re at now. This is a viable option, and even if telehealth isn’t an option, you can always just get on the phone. As a lung cancer specialist, a lot of the information I need can be garnered from test scans and images, so frankly, the physical exam has some role, but is not the mainstay of how a lot of the decisions are made. So even if I see your scans and I talk to you, I can give you an opinion over the phone, it takes me 15 to 20 minutes, and a lot of times, those visits may not even be charged, depending on who you actually ask to give you an opinion. 

Dr. Nicole Rochester: 

I’m a huge proponent of second opinions, I’ve talked to so many patients and family caregivers who think that they’re offending their doctor if they ask for a second opinion, so I appreciate that you brought that to the forefront and you deserve to have multiple opinions as you’re making these very important life-changing decisions.

Dr. Nicole Rochester:

What are some things that patients of color can do in order to protect themselves from these inequities that you’ve talked about, starting with diagnosis and treatment, what can we do? What can patients of color do? 

Dr. Olugbenga Okusanya: 

So, I think the number one thing is to ask questions, the number one thing is to say, what are my options? What am I dealing with? What should I do or what shouldn’t I do? And to really make sure you get the most at that time when you see a physician, because that is really what we’re there for apart from the surgery, I’m really there to be an educator. I teach as much as I operate on a daily basis whether it be the medical training is whether in my patients, my job is to communicate information back and forth, so you really want to spend the time asking questions and getting as much information out, as much as you can. Number two is, see a specialist. There’s also very good data to indicate that as a Black patient, if you see a board-certified thoracic surgeon, you are more likely to get lung cancer surgery than if you were to see a surgeon of unknown specialization, a general surgeon. So clearly the training gives specialist the ability to make finer determinations and discernments that I think in large part favor Black and minority patients, so you want to find someone who deals with these disease processes all the time because they’re going to look at it in a much higher level and look at it with a lot more granularity. 

Dr. Nicole Rochester:

Just have to repeat what you said, you said, I teach as much as I operate. That just really resonated with me, and I think that…that’s so incredibly important. Doctor means teacher, right? I think that’s the Latin…we are obligated to teach our patients, so I just really appreciate that that’s something that you incorporate in your daily practice.

Dr. Patil:                     

Lung cancer patients are certainly at very high risk of complications from COVID-19. And it’s understandable, especially given the kinds of treatments that patients with lung cancer receive, that there’s a lot of them will wind up having compromised immunity which makes them at increased risk for adverse outcomes from COVID-19. That being said, I think it’s really important that this be balanced with the actual risk of untreated or inadequately treated lung cancer, which is also a major medical concern. What I tell patients is that, at least at our institution, we do everything we can to create an environment that is as safe as possible from a COVID mitigation standpoint.

But at the end of the day, untreated lung cancer can have a very aggressive course, and so making sure that patients understand that as we try to move things to a more telemedicine type approach, that there are some things where you really just have to come and see your doctor. Not everything can be done virtually.

I think telemedicine is helpful for patients who have very stable disease and are on anti-cancer treatment, so specifically a patient on targeted therapy, for example.

A pill once a day. Their last scans show that they’re doing really well. They feel well. They’re exercising every day. That patient, probably we can do a visit virtually and just make sure and check in that there’s nothing new or concerning that’s come up.

The other patient that probably I can see a role for telemedicine is someone who had, let’s say, a Stage 1 lung cancer that was treated with surgery, and we’re just monitoring them on surveillance. That patient probably doesn’t have to come into the clinic to see us. But in general, the thing about lung cancer is that most patients are getting some kind of chemotherapy or immunotherapy and will be coming into an infusion center, and so what I would tell patients is if there’s any new or concerning symptoms, to a very low threshold for seeking an in-person evaluation.

What Are Common Lung Cancer Mutations?

Transcript:

Katherine:                  

Is it necessary to retest at any time?

Dr. Patil:                     

In general, I strongly advocate that patients who are on targeted therapies obtain additional molecular testing after they’ve progressed, and the reason is the following.

Cancer cells evolve resistance mechanisms to overcome targeted therapies and understanding these resistance mechanisms can be quite helpful in designing next lines of treatments.

A very good example of this is in EGFR lung cancer. The very first type of targeted therapy for EGFR positive lung cancer was a drug called Erlotinib. What we had seen was that when patients were on this drug, Erlotinib, they would respond, and they would do really well for a period of time.

But after a period of time, patients would progress on this therapy, and a very common mutation that we would find, once they progressed was a mutation called T790M. By biopsying this patient and finding this mutation, it was very helpful because it allowed the medical community and researchers to investigate a new drug called Osimertinib, which can overcome that resistance mutation.

And we’re learning a lot about resistance pathways and resistance mutations in lung cancer, so I think it’s very important that patients who are on targeted therapies specifically get retested and re-biopsied.

How Can You Access Personalized Lung Cancer Treatment? Resource Guide

Transcript:

Dr. Patil:

In general, I would highly recommend patients consider clinical trials. I think there’s a couple of things to point out. It’s very important to remember that clinical trials are evaluating novel therapies as compared to current standard best practice. So, placebos are rarely used in cancer research unless there’s no known effective therapy. It’s important to remember, it’s not ethical to have someone take placebo if there’s known treatment that work, so when a patient enrolls in a clinical trial, sometimes they don’t know which treatment they’re getting, but at least they will know that whatever treatment they’re getting is the best current standard of care.

I want to also point out that clinical trials really answer, in my mind, two important questions. The first question is, is the new treatment safe? And does the new treatment work better than current standard of care? These are really important questions for advancing the field, especially in cancer research. Clinical trials are a small part of the research. I mean, when a drug that’s getting introduced into a clinical trial, it’s sometimes helpful to think about all the investment that has gone in before them. The drug has to be discovered, created.

It has to be purified, tested in animal studies, before it ever reaches human studies. And so, there’s only the most promising agents are actually ever introduced at clinical trials, and there’s a lot of data to show that the biggest barrier for completing clinical trials, and therefore understanding which treatments are effective, is really participant enrollment.

I think there was a recent study that showed that about, I think less than five percent of patients, less than 1 in 20, with cancer will ever take part in a clinical trial, Therefore, if a patient has that opportunity, I would strongly encourage them to consider it.

Lung Cancer Treatment: How Do Targeted Therapies Work?

Lung Cancer Staging: What Patients Should Know

Transcript:

Katherine:                  

How do the newer therapies differ from the more traditional chemotherapy?

Dr. Patil:                     

Chemotherapy is still an important tool in an oncologist’s arsenal.

It works by killing, or rather it works by affecting a cancer cell’s ability to divide and grow. The logic here is that since cancer cells typically grow faster than normal cells, chemotherapy is more likely to kill cancer cells. It should be noted that while that is true, there are certain cells in the human body that grow very quickly as well, such as hair follicles, the lining of the mouth, and cells within the bone marrow. And so, as a result, it’s very common that the side effects of chemotherapy typically affect these cells, so you typically see hair loss. You see mucositis, or inflammation of the mouth, diarrhea, and low blood counts, and this a general side effect of chemotherapy.

Katherine:                  

Are there common side effects for some of the newer therapies as well?

Dr. Patil:                     

That’s a great question and the way I’m going to answer that is it depends on the mutation that the targeted therapy’s affecting. So, a mutation that I’m going to use as an example is a mutation called EGFR. Now, this is a mutation that we see in lung cancer that causes cancer cells to grow, divide, and metastasize.

But EGFR is interesting because it also is found in normal cells, and specifically it’s found in the cells of the skin and the gut lining. This is an example where you’re giving a very targeted therapy that’s trying to attack just the cancer cell, but because normal skin cells and gut cells have this EGFR receptor, the side effects there tend to be rash and diarrhea. Now, that’s unique to EGFR. There are other drugs such as the ALK mutation or the ROS1 mutation that do not have this side effect because that specific receptor is not found in the human body.

Katherine:                  

Oh, I see. Well, how is the effectiveness of treatment monitored?

Dr. Patil:                     

Typically, I have the philosophy that patients generally know their body and can tell when symptoms are getting better or worse. So, as a guiding principle, I rely on patient input very heavily. That being said, I corroborate that experience with some testing. In my practice, I frequently use what we call serum tumor markers, so these are very nonspecific-like tests that sort of let us know if there’s cancer type proteins in the blood that we can detect while they are on targeted therapy.

And then additionally I would recommend that patients get scans frequently, at the minimum every three months if they are on targeted therapy and doing otherwise well. That includes a CT scan of the chest and abdomen, and in certain cases, an MRI of the brain, if there were brain metastases before.
