Why should you ask your doctor about biomarker testing?

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

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

So why do the test results matter?

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

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

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

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

The results could also show that your cancer has a mutation or marker that may prevent a certain therapy from being effective, sparing you from getting a treatment that won’t work well for you.

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

How can you insist on the best lung cancer care?

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

What Are the Goals of Lung Cancer Treatment?


Transcript:

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:

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

Dr. Wakelee:

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

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

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

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

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

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

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

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

Katherine:

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

Dr. Wakelee:

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

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

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

Katherine:

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

Dr. Wakelee:

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

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

Katherine:

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

Dr. Wakelee:

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

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

Katherine:

Do you use imaging at all?

Dr. Wakelee:

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

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

Katherine:

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

Dr. Wakelee:

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

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

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

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

Katherine:

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:

Transcript:

Katherine Banwell:

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

Dr. Preeshagul:

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

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

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

Katherine Banwell:

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

Dr. Preeshagul:

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

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

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

Katherine Banwell:

Are there specific biomarkers that affect lung cancer treatment choices?

Dr. Preeshagul:

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

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

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

Katherine Banwell:

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

Dr. Preeshagul:

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

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

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

Katherine Banwell:

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

Dr. Preeshagul:

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

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

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

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

Patricia:

How is genetic testing changing the landscape?

Dr. Edelman:

So, genetic testing – and in this case the testing of the tumor, not the germline, not the individual – has been very, very crucial. If you go back about 20 years ago, there was a family of drugs called epidermal growth factor receptor inhibitors or EGFR inhibitors.

And the basic science at the time made it look like these would be best combined with chemotherapy in squamous cell carcinoma. And as it turned out, combined with chemotherapy they weren’t very useful. But as single agents, there were these occasional very dramatic results.

So, that came at a time when we were able to evaluate tumor DNA, sequence it with some degree of ease at a reasonable cost. So, there was a discovery of specific mutations, which were targeted by these drugs. So, it was sort of interesting in that it was the clinical observation that led to the discoveries in biology, not really the other way around.

But then that in turn resulted in looking for other mutations, which were found, and then the development of other drugs – in some cases, the repurposing of other drugs for those. And now we have about a half a dozen very validated targets, each one of which in a small slice of the population – between say 1 percent and 5 percent – 10 percent of the lung cancer population – but these – if the patient has within their cancer that particular mutation, these are drugs that are 80 percent-plus effective and frequently can be administered with relatively little toxicity.

And usually they’ll give them benefit for one-plus years or more. So, that’s been an example of progress there.

Transcript:

Patricia:

Let’s start with an overview of lung cancer’s research. Can you tell us a little bit about the field right now?

Dr. Edelman:

So, I think the field has been remarkable over the last few years. There’s been more progress, more drugs, more things that have happened in the last five years than probably the prior 50. It’s been an amazing time both for developments in microbiology as well as in immunotherapy of the disease, which is exciting for all concerned.

For patient’s, of course – really a promise of longer, better lives, even cures where we previously did not see any in advanced disease. For the scientists – an amazing amount of new information. And for clinicians and clinical investigators – just almost too many questions for us to answer.

Patricia:

It sounds like the field is really advancing quickly. What do you attribute that to?

Dr. Edelman:

Well, you know, I think there are a number of things. Everybody always talks about breakthroughs, but breakthroughs really happen after decades of other work. And what’s happening now is really a result of many, many years of different types of work. There were our colleagues in immunology who built this area of cancer immunology for many years – I have to say with much skepticism from many, myself included.

The advances in molecular biology – our abilities to do things with tumors to determine genetics at a rate and a pace and a cost that was previously unimaginable. All of these things have developed in the last few years but really are a result of the decades of work before that. If you look at immunotherapy – probably one of our biggest areas of progress – the roots of that are a century old. So, nothing’s really new. It’s just now we have the technology and the ability to really use it. And then I would also say that we’ve created the infrastructure that lets us test this – the people who have done the studies, the endpoints for the studies, the expertise in doing clinical trials – that also was there for decades, and we frequently were kind of ridiculed at times.

Oh, you’re just testing this drug against that drug, but the reality is is it was those incremental advances. It was the ability to know the endpoints, to refine the populations, to develop the infrastructure that allowed for all of this to happen.

Patricia:

Dr. Edelman, as a researcher in the field, tell us why you’re hopeful about lung cancer research.

Dr. Edelman:

Well, I think that we have gone from trials with very small incremental improvements and frequently a very slow degree of progress where if we had a positive study every two or three years, we were thrilled – to the point where we’ve had an avalanche of positive studies. I don’t think my younger colleagues know what a negative trial looks like anymore. Even our negative trials are pretty impressive. We’ve had studies where an immunotherapy agent was compared with chemotherapy. And it was designed to show that the drug would be better.

And it was just as good, and that was a negative study. That’s the correct interpretation, but still I would point out that that’s quite remarkable because these other drugs had taken us 25-30 years to develop. And now we have another drug with a very different mechanism of action that’s as good potentially. That’s impressive. I think we’ve just had an amazing degree of progress in the last few years. We have far more drugs. We understand far more about the disease – the technology at every point from diagnosis to assessment of response to the ability to evaluate better what we’re not doing well. So, our studies now frequently have biopsies before, during, and after treatment in a way of trying to figure out why is stuff working or not working.

Back in 2006 or so, I proposed a study. We ended up doing it, but it took two or three years because we were requiring a biopsy result – actually, not even a new biopsy but just an archived specimen from the original biopsy to determine eligibility, and there was strong pushback that we would never be able to do that. And now, we routinely are getting biopsies and re-biopsying, and that’s over a brief period of time.

So, we’re getting to get better understanding of the disease, and why stuff works and doesn’t work. And I think that that’s why our progress will accelerate. And I would again emphasize progress only happens – real progress – only through clinical trials. We’ve cured a lot of mice for many decades. A mouse is not a person. You actually have to do the studies patient by patient, and I think we are making substantial progress. We almost have too many things to test right now.

What Patients Should Know About CT Scans and MRIs

As patients, we normally rely on our doctors to tell us which tests and medications to take for the betterment of our health. Rarely do we question them since they know a whole lot more than most of us when it comes to medical ailments and overall health. However, that doesn’t mean you can’t find out more about the various suggestions doctors make.

If you have an ailment in the body and your doctor finds it hard to determine exactly what it is, they will likely ask you to get either a CT scan or MRI done. The tests are used to provide a detailed view of your internal body to help determine the ailment. We breakdown the two for your better understanding:

CT Scans

CT scans provide imaging using x-rays at different angles. This scan is more in-depth as compared to an x-ray. X-ray tests use a beam of radiation from a set angle and display the image. Since a CT scan uses a series of radiation beams at different angles, it slices the same image up, giving a 3D view so doctors can understand the ailment better. With the help of a computer, an image is produced. CT scans can help determine ailments such as cancer, bone injuries, and chest and lung ailments.

MRI

Magnetic resonance imaging (MRI) uses a magnetic field instead of radiation and provides a more detailed image of the body which also includes soft tissues along with the internal body. It is used to help diagnose the following:

  • Brain injury
  • Cancer
  • Damaged blood vessels
  • Spinal cord injury
  • Stroke
  • Multiple sclerosis
  • Bone infections
  • Damaged joints
  • It can also be used to ensure that various organs are healthy.

Both methods are noninvasive and rely on heavy technology. But when it comes to CT scans, more and more hospitals are opting for mobile CT scanners, which make it easier for them to manage.

Getting Ready for the Test

Preparing for CT Scan and MRI is slightly different. With CT scans, your doctor may recommend you take a contest dye. The dye helps highlight the scanned region more and is generally consumed when scanning the abdomen. It is important to notify your doctor if you have any allergies because you may react to the dye. If you’ve previously had reactions to prednisone (a steroid), iodine, or seafood then the doctor should be immediately notified. Other than that, the doctor may ask you not to drink or eat several hours before the test.

For an MRI, the one thing you need to make sure is that you are not wearing anything that can be detected by magnets. This means, no jewelry, watches, hearing aids, glasses, and other items that may have a metal can be worn during the test. In some cases, a gadolinium dye may be recommended which is injected into the hand or arm. The dye highlights certain details in the imaging and rarely results in any type of reaction. The test can be lengthy for some as it takes anywhere from 30-45 minutes, so if you are claustrophobic, you may want to discuss that with your doctor since you are required to stay in a closed space for that period.

The Test

  • CT Scan: You will be asked to put on a robe and remove jewelry and other metal objects so they don’t have any impact on the image produced. The scanner itself is a doughnut-shaped machine and you lie on a flat table in the middle. The table starts to move back and forth and x-ray tubes fitted into the scanner send out beams and different angles. They pass through your body to the other end of the scanner. The test is painless but make sure you are comfortable because you will be asked to stay still as the scan is going on.
  • MRI: The MRI machine is a long narrow tube that is open at both ends. Like in a CT scan, you lie down on a flat movable table that slides into the tube. As you slide in, the table stops at the specific part of the body being examined and a magnetic field is created and radio waves are directed to the body. The machine does make tapping and thumping noises, so the technician will likely offer earplugs to block it out.

Understanding the Test Result

After getting either a CT scan or MRI done, you will need to consult your doctor. Unless you are a trained doctor, the images will make little to no sense to you. You will need to consult a radiologist that can explain the results to you. In case of an ailment, they will usually recommend you consult a specialist, depending on the ailment, that can assist you further.

As a patient, it is important for you to understand the tests and treatment doctors recommend. Most of the time, you can consult your doctor and they will be more than willing to give you the information you need. Knowing makes it easier for you to undergo the tests and treatments with a little more ease.
