Lisa Hatfield:

Dr. Sabari, how do you explain non-small cell lung cancer to your patients and their care partners and families?

Dr. Joshua Sabari:

Yeah, so non-small cell lung cancer is a common cancer in the United States. It’s actually the third most common cancer. And really, you know, non-small cell lung cancer makes up multiple different histologies or types of cancer in the lung. The most common being adenocarcinoma, which is probably about 60 percent to 70 percent of non-small cell. We also hear about squamous cell cancer. And what this means is what is the original cell where the cancer arose? So adenocarcinomas occur in gland cells.

Whereas squamous cancers occur in cells such as the lining part of the lung. And it’s important to know what type of cancer you have because these are treated differently. And when you think about non-small cell lung cancer, we said there are many different ways that people can present. Some people can have shortness of breath, cough, you know, and weight loss. Whereas other people may have no symptoms at all.

So again, the important thing here is that lung cancer can be diagnosed in anybody. All you really need to have is lungs. We see lung cancer in people who’ve smoked in the past, but we also see lung cancer in people who’ve never smoked. And that brings me to a really important point. Once we understand the histology, the type of cancer that it is, we then want to understand some of the biomarkers, right? What are biomarkers?

Biomarkers are distinct sort of entities that help us better understand things about your cancer. And allow us to potentially match people to therapies. So two biomarkers that we generally think about, one is molecular or mutational biomarkers. These are the mutations or abnormalities that led to the cancer. Two kinds of mutations. One is a germline mutation, which is inherited from mom and dad and has a risk of being passed on to your children.

These are uncommon in lung cancer. The second type is called a somatic mutation. And these are mutations that are acquired from the environment, from smoking, for example, from pollution, from radon. And these are not generally inherited mutations. So really important to understand mutational profile and ask your doctor, what is my mutation? Because we can then match people to targeted therapies. The second biomarker that is really important is something called PD-L1 or programmed death-ligand 1. I know it sounds exotic.

But that’s a biomarker that helps us guide how likely immunotherapy will work in your cancer. If the PD-L1 expression is high, greater than 50 percent, immunotherapy may be a very good option. If the PD-L1 expression is low, immunotherapy may sometimes be used, but more commonly in combination with chemotherapy. So my activation tip here is know what type of cancer you have, the histology. Whether it be adenocarcinoma or squamous cancer. And equally as important, know your biomarker, what mutation is driving your cancer and what PD-L1 expression your tumor harbors.

How Can We Advance Equitable Access to Precision Medicine in Lung Cancer Care?

How Can We Advance Equitable Access to Precision Medicine in Lung Cancer Care? from Patient Empowerment Network on Vimeo.

With non-small cell lung cancer (NSCLC) precision medicine, what are disparities and strategies to equitable access? Expert Dr. Samuel Cykert from UNC School of Medicine discusses disparities, strategies to overcome disparities, and proactive patient advice toward optimal care.

[ACT]IVATION TIP

“…I know you do electronic health records, and as soon as this visit is done, you have data about my visit, so have you thought about creating a real-time registry to see how I’m progressing with my care and see how others are progressing with their care, whether to make sure that we don’t have missed appointments and to make sure that I’m not falling behind where I should be.”

Transcript:

Lisa Hatfield:

Dr. Cykert, are there any disparities in access to biomarker testing for Black and Latinx patients with lung cancer compared to other racial or ethnic groups, and if so, what strategies or initiatives can be implemented to address these disparities and promote equitable access to precision medicine?

Dr. Samuel Cykert:

Yeah, biomarker testing followed up by precision medicine is really fairly new in the last half-dozen years, so there haven’t been a lot of studies done looking at how well we’re doing in different groups, but there’s a journal called The Journal of Clinical Oncology and precision medicine that published such a study in 2022.

And what that showed…and again, keep in mind that in a lot of…as they do in a lot of database studies, they are a couple of years behind, but what they showed in looking at the cases of over 20,000 patients, is that on first time testing, we talked about initial biopsies, when the initial biopsy is tested, there is actually about a 7 percent difference between Black and white patients with the white number being only 37 percent and the Black number being 30 percent, so that was low all the way around.

And then if you look at any biomolecular testing at any stage of the cancer, those numbers change to around 55 percent for white patients and 44 percent for Black patients, and I want to point out that for Asian patients and Latinx patients, the numbers were also low, but there weren’t enough patients in the database to achieve statistical significance, but it looks like things are going in the wrong direction there too, and when you think about it, in the state of the right now, those numbers ought to be close to 100 percent for everybody, at least in some of the basic markers like ALK and EGFR and PD-L1.

So there’s a lot of work to do. So there is a disparity. It has been documented, but we’re not getting perfect care to even anyone, and in the ACCURE (Accountability for Cancer Care through Undoing Racism and Equity) Study that I had described a little bit earlier, where we did an intervention, we created real-time transparency through up-to-date electronic health records and digital data of where patients were in their care, we were able to create a real-time registry to know what had been done for every patient, and in the case of precision medicine, this would be so easy, because you basically put every patient that’s had a lung cancer biopsy in the registry, then you have another column in the registry tested for X, tested for Y, tested for Z, and then you have a next column that says, treated for X, treated for Y, and treated for Z. We have the digital information now to do all this in real time, and we have to build the systems to do it.

Lisa Hatfield:

Could you share any examples of successful initiatives or programs aimed at improving the implementation of biomarker testing in lung cancer and what factors contribute to the success of these initiatives, and how can they be replicated or scaled in other healthcare settings?

Dr. Samuel Cykert:

I’ll have to plead my ignorance on this question because I haven’t talked to enough cancer centers on whether or not they’re creating real-time registries for whether all their patients with probable lung cancer are, [a] getting biopsied promptly, [b] getting biomarker testing, and then following those patients over time to see if they’re getting the treatments to match to that, so I know that at my own institution at the University of North Carolina Lineberger Cancer Center, we’re actively talking about building these systems, but we haven’t built them yet.

And so going back to the work that our UNC team has done in partnership with Greensboro Health Disparities Collaborative, we’ve done an intervention with real-time transparency in lung cancer treatment and breast cancer treatment, and real-time quality improvement and audit and feedback for accountability in those treatments and using navigation, particularly for high risk patients to make sure that they’re able to follow through with their diagnosis and treatment.

So with that combination in lung cancer, we got almost perfect care, 96 percent and 95 percent completing treatment, so there’s no reason that the same system cannot be applied to biomarker testing and biologic and immunotherapy, and we need to look at it and implement it and apply it as soon as possible, because when you think about all this, and I’m not just talking about cancer, but when you’re thinking about the whole picture, when you look at, for instance, Black, white disparities, whether it’s in cardiovascular care, whether it’s in diabetes, whether it’s in cancer care, if you look at the result of that in one year, if we brought up care to benchmark levels of the Black community on all those things, we would save 74,000 lives a year.

That’s incredibly impactful. And we need to quicken up the pace of doing this. I’ve been a disparities researcher and intervention researcher for over 20 years, and people really haven’t taken note of really doing interventions until the last five or six years. We need to pay attention, we need to move. It’s important. People’s lives depend on it. And care improved for everyone with these systems, it improved for white patients too. It’s not a zero-sum game.

Lisa Hatfield:

I’m wondering, as a patient, is there anything that I can do or that a patient can do to request or to ask if they use real-time data, that institution to help with the treatment or help with testing or whatever, is there a question the patient might be able to ask to ensure the real-time data is used? Because I imagine it’s not being used as often, so it could be, like you said, there probably isn’t a system in place.

Dr. Samuel Cykert:

Here’s my double activation tip. So at an institution, you don’t know if you have a problem until you look. So the first problem is, as I go back and look behind, am I making sure whether or not I’m seeing disparities, whether it’s a man, woman, Black, white, Latinx, do we have disparities in our treatment application and treatment outcomes in our institution? Because if we look at that, we can start brainstorming on how to possibly fix it, and then the second thing is, I know you do electronic health records, and as soon as this visit is done, you have data about my visit, so have you thought about creating a real-time registry to see how I’m progressing with my care and see how others are progressing with their care, whether to make sure that we don’t have missed appointments and to make sure that I’m not falling behind where I should be.

Lisa Hatfield:

Great, that’s perfect, thank you. Having the patients be…have that accountability too, to ask the question, if that exists, that real-time data, if there’s a way to use that. So thank you, I appreciate that myself personally, so thanks.

Understanding Small Cell Lung Cancer Treatment Options

Transcript:

Katherine:

Dr. Sen, you are a leading researcher in the field. What is the latest research news that you can share with us about small cell lung cancer?

Dr. Sen:

There’s a lot of great research going on in my lab and labs all across the world. I think for the first time in a very long time, we are really trying to dissect the biology of small cell.   

It has been a research in making for many years. I think we have now really come to a point where we are really trying to understand the disease. I’ll go into a little more about the questions you are trying to answer. So, one of the main questions or one  of the main things that kind of is a hurdle to getting durable treatment options is that the frontline chemotherapy and immunotherapy doesn’t work as well as they should even for the approved regimens, which is the chemotherapy and the immunotherapy.  

The patients often do not have durable benefits. Even if patients have durable benefits, it’s only in a very minority of patient population which means in only about 10 to 15 percent of the total patient population actually do have any benefit from the frontline treatment. So, the main question that we are trying to answer is that why do these patients not respond to immunotherapy and chemotherapy in the frontline.  

What are the mechanisms of resistance to chemotherapy and immunotherapy? Primary resistance, what I mean by primary resistance is that patients who never respond. The disease comes back even while they’re getting the frontline chemo. So, the primary resistance, the mechanisms. Of course, when they have acquired resistance after the maintenance regimen when they come back, why are these patients having this acquired resistance to chemotherapy and immunotherapy? Because only when we understand resistance mechanisms will we be able to then come to the combination strategies.

That’s the next area of research is that once we understand the mechanism of chemotherapy and immunotherapy resistance is then coming up with effective combination therapy. So, what should we combine with immunotherapy in order to make immunotherapy better? I’ll give you an example from the research that we did. 

So, our lab focus is, as I said, on making immunotherapy better. What we understood is that there are certain epigenetic modifiers like LSD1.  

Repressing these, repressing LSD1, with a small molecule inhibitor actually augments or benefits the response to immunotherapy. So now, we are looking at LSD1 inhibitors in combination with immunotherapy. That’s one area that we are focusing on. The second are that we published extensively on is DNA damage response inhibitors which really works in combination with immunotherapy and makes immunotherapy response better.  

Now, we are investigating that in the lab the combination strategies of combining these DNA damage response inhibitors with immunotherapy. So, combination strategies. I think always coming up with novel targets. I will mention there are many novel targets that are right now in the clinical trials actually showing really, really encouraging data.  

I’m talking about DLL3 targeted BiTEs or ADCs we have seen that are showing preliminary data. We have seen a really good really good response in patients. So, finding these targets that are very specific for small cell and that can work in these unique population of patients.  

So, DLL3 targeted agents. There are agents that target B7-H3. So, we are looking at these novel targets and where they could fit in the current therapeutic regimen. Finally, since small cell lung cancer is not a surgical disease, we have to look for other options to find biomarkers. So, liquid biopsy. Liquid biopsy, what I mean by that is understanding the disease not just from tissue but also from blood.  

There’s a lot of research that’s happening in understanding the biology of small cell from blood draws from these patients.  

So, the field of using liquid biopsy or understanding the disease from blood draws is one of the areas that many labs, including ours, are focusing on, and how we can utilize these blood samples to then monitor the disease and also understand the resistance mechanisms to various drugs. I think these are the areas that we are investigating and seems, to me, very important areas that we need to address in order to really manage small cell lung cancer.   

Katherine:

What do these advances mean for small cell lung cancer patients? Are you hopeful?  

Dr. Sen:

Oh, yes. Of course. We’re always hopeful. That’s the goal, right. The goal is to have effective therapies that work and that works for a long time. That also benefits the patients in terms of quality of life which means without very severe adverse effects.   

So, very hopeful. Because I think what was limiting us for all those years for the last 40 to 50 years is that we really did not understand the complexity of small cell lung cancer. It is a very complex disease. It is very different from non-small cell lung cancer which has these mutations that you can target drugs against. So, there are this EGFR mutations and KRAS mutations in non-small cell.  

But small cell, it’s not that. It is not a disease where we have these GATA function mutations that we can devise therapies against. It’s a very different disease. The disease is aggressive. The disease progresses fast, and it also changes its physiology very fast. So, I think for the first time, we really are trying to understand the biology. What that helps is then to come with very informed decisions about therapy.  

So, yeah, I’m very hopeful. Because I think we have now targets that we are actually seeing benefits in patients. I think the more and more we understand resistance mechanisms, we’ll also be able to manage that better.   

Katherine:

That’s very promising news.

How do test results impact care? 

Dr. Sen:

So, you know, once the doctor has confirmed the small cell lung cancer and we have confirmed what stage it is at – what I mean by staging is that it could be either a limited stage disease which is an early stage small cell, or it could be an extensive stage of small cell. The treatment for those two are quite different. So, if it is an early stage or limited stage, patients are usually treated with chemoradiation. If it is an extensive stage or a metastatic small cell, then patients are usually given a standard of care which is chemotherapy in culmination with immunotherapy which is an antibody against PD-L1.  

Katherine:

You’re talking about treatment options that are currently available for small cell lung cancer. What about targeted therapies?  

Dr. Sen:

There aren’t very many therapeutic strategies that are targeted therapies as we speak like we hear from non-small cell lung cancer.  

So currently, like I mentioned, the frontline treatment for small cell lung cancer is with chemotherapy and immunotherapy and maintenance with immunotherapy alone.  

Once the patient relapses, which often is the case – all patients actually have resistance to the frontline chemo-io (chemoimmunotherapy) at some point in time. Once they have a relapse disease, the second line of therapy until now is with either topotecan or irinotecan which are two topoisomerase inhibitors or with lurbinectedin which is in the second line.  

So, when it comes to targeted therapies, so far we a have seen, you know, the conventional way that we think about EGFR inhibitors or KRAS inhibitors, it hasn’t been the case so far with small cell lung cancer. It’s very limited in the current approved setting. But there are many clinical trials that are investigating several targeted therapies that are either targeting – I can speak about that more as I talk about research strategy. But there are many targeted agents that are targeting surface targets like DLL3, B7-H3, or SEZ6. There are other targets that are targeting things like DNA damage repair, proteins, or epigenetic regulators like LSD1. But so far in the approved setting, it is quite limited.  

Katherine:

When we look at what therapies are available, what treatment options are available, what are some typical side effects? How are they managed?  

Dr. Sen:

Some of the major side effects that you see, especially with a frontline chemo-io (chemoimmunotherapy), are very common like you see with other cancer types. Also, it’s usually myelosuppression.  

I think it is prevented or is managed either by dose reduction or treatment delays or treated with transfusion. There has been research that CDK4/6 inhibitors, trilaciclib, when treated with in combination with chemotherapy can bring down the side effects that we see with chemotherapy.  

Some of the immunotherapy related adverse events includes pneumonitis, colitis. They are usually treated with early steroids, treatment withholding, and also it could be leading to permanent discontinuation of the treatment if the adverse events are really severe. Those are mainly what we see we the chemo-io (chemoimmunotherapy) regimen that is given up front.  

Katherine:

Okay. What questions should someone be asking about their proposed treatment plan?  

Dr. Sen:

Right. So, I think, of course, first is what stage. The treatment will depend upon the stage of small cell. Usually, on the frontline, everyone is given chemotherapy and immunotherapy. 

It’s a systemic therapy that’s being given. But I think the patient should be asking questions like are there clinical trials available for me. Because there are multiple clinical trials right now in the frontline and the second line setting.  

So, I think definitely the patient should ask about the clinical trials that the qualify for. In terms of contributing to research, I think if there are options for them to either sign up for blood collection protocol or for tissue collection protocol, I think the patient should definitely enroll for that.   

Because that really helps our research strategy. But in terms of treatment, I think they should ask about available clinical trials that they qualify for.  

Katherine:

Let’s turn to clinical trials then. Patient participation, of course, is essential to finding new and better treatments. What would you say to someone who’s hesitant to participate in a clinical trial?  

Dr. Sen:

Yes. I mean, that’s often the thing. We hear about these novel drugs. They’re in trial. For a disease that’s that aggressive, I think once there is a relapse, I think clinical trials could be a very good option for patients. These are novel drugs that have come out of very robust research that we do in the lab. They can often work quite a bit. So, I think, of course, talk to your physicians. Talk to them at length about whether you do qualify for it. But if there is a trial at the center that you’re getting treated at and if the doctor advises that, I think enrolling in a clinical trial could be a very good option for patients, especially in the aggressive setting where there are not many options available for patients.  

As I mentioned here, research is my true north. I mean, all my lab does is understanding the biology of small cell. It’s extremely essential that we actually try to get the knowledge of the patient tumor. So, if you have availability of contributing either in terms of tissue or blood to research, I think I would advise and encourage patients to definitely contribute to that.

And finally, before we get into the discussion, please remember that this program is not a substitute for seeking medical advice. Please refer to your healthcare team about what might be best for you. Well, let’s meet our guest today. Joining me is Dr. Yelena Janjigian. Dr. Janjigian, welcome. Would you please introduce yourself? 

Dr. Janjigian:

Thank you so much, Katherine, for this opportunity. My name is Yelena Janjigian. I’m a medical oncologist. And I oversee the GI oncology service at Memorial Sloan Kettering Cancer Center in New York. We’re a large group of doctors, over 40 physicians who treat everything from esophagus cancer to rectal cancer. And my research focus and my passion has been in developing new treatments for patients with stomach cancer, so I personally focus on this disease clinically and from research perspective.  

Katherine:

Okay. Lovely.  

Well, thank you so much for joining us today. I’d like to start by learning about the latest research news. Are there recent advances in gastric cancer that patients should know about? 

Dr. Janjigian:

That’s a great question. The field of gastric cancer research has accelerated and evolved immensely over the last three years. We’ve had several important approvals for treatment of metastatic disease both for biomarkers selected population and immunotherapy targeted therapies. So, there’s been a lot of research, a lot of effort and some positive data that the patients and clinicians should be aware of.  

Katherine:

And what excites you about the research you’re involved with? 

Dr. Janjigian:

I’ve been focused on gastric cancer for nearly two decades. So, my recent advances have really helped to understand how we can improve patient’s survival better, potentially cure more patients, and understand the different subsets of cancer treatments and patients with gastric cancer understanding that not all gastric cancer is the same.  

So, I think being able to zoom in on different subsets and target personalized approaches for each individual patient is why I stay in research, why I stay in gastric cancer research because we’ve been able to make some major breakthroughs.  

Katherine:

That’s excellent news. How can patients stay up to date with treatment options? 

Dr. Janjigian:

That’s a great question. And recently there’s been a lot of resources online through both the big pharma really educating patients with patient-friendly handouts. And many of my big recent papers when we publish them in big journals like Lancet or Lancet Oncology, for example, or JCO, there’s always a patient-friendly handout that comes with that data that helps patients understand some of the endpoints, how do we describe why this study is positive? 

Or why is the FDA decided to approve the drug? So, there are many patient handouts that come with some of these papers. And it’s interesting, a lot of my patients come in. When they see me, they say, “Oh, it’s so good to finally meet you. I’ve watched a lot of your videos.” So, because of COVID actually, a lot of the scientific content that used to be just in in-person meetings behind doors for doctors, now it’s all online because a lot of these scientific presentations are now made for virtual content as well. So, patients have access to it. That’s double-edged sometimes. It’s a little bit of an information overload, and it may actually make patients feel more anxious than reassure them, right? Because it’s a lot of jargon and not too – but some patients find it helpful.  

Katherine:

Yeah, I can see that. It can be a double-edged sword.   

Dr. Janjigian:

Yeah.   

Katherine:

Well, thank you for that advice. So, now that we’ve heard what’s happening in research, let’s review some more basic information about gastric cancer. First, gastric cancer is sometimes referred to as stomach cancer. Is that the same thing, or are both terms correct?  

Dr. Janjigian:

Yeah. So, stomach is really where the cancer starts. But we can talk about stomach or abdomen. But gastric and stomach are the same tumor location basically. What’s interesting actually, some patients also have tumors that start at the bottom of their esophagus and extend into the stomach. So, biologically a lot of these cancers behave similarly. In fact, in United States the most common location for these cancers actually is in between the gastric esophageal junction and the stomach.  

So, it’s in the location in of the cancer that’s at the very top of the stomach. But in short, stomach cancer and gastric cancer are interchangeable. And as I mentioned, for many of our viewers, actually gastro-esophageal junction is also part of the same disease.  

Katherine:

Could you tell us what tests are used to diagnose gastric cancer? 

Dr. Janjigian:

Most of our patients, when they come in to see me, by then the diagnosis of cancer has been made because I’m on oncologist.  

In clinical practice, patients often present with vague symptoms or no symptoms at all. And that’s an important point for our clinicians to understand. In patients who have chronic acid reflux or have, for example, other risk factors such as H. pylori infection, often they end up getting endoscopy at the time, for example, for their first colonoscopy. So, the age of colonoscopy, the first colonoscopy has is getting earlier and earlier with each update, because colon cancer is increasing in incidents in younger adults. So, sometimes patients present and get first endoscopy, for example, which is an upper test with a camera when they’re getting their colonoscopies. In other patients, unfortunately, they present with more progressive symptoms. Often, it’s difficulty swallowing, regurgitation of food, and weight loss, which is obviously very dramatic.  

And so they end up getting an endoscopy because of that and referred by their doctors.   

Katherine:

How is gastric cancer staged? And what do the stages mean? 

Dr. Janjigian:

Yeah. So, the most important part of the staging of gastric cancer and what patients ask me, “What is my risk of cancerous recurrence? What is my stage?” Really what it comes down to is the depth of invasion. So, it’s not only the size of the tumor, but how deep is it going into the muscle of the stomach, because stomach and your esophagus are basically a muscular bag, right? And so how deep is the invasion of the tumor into the wall? And also how likely are the lymph nodes to being involved? So, we assess it based on clinical symptoms such as swallowing difficulty and so forth. But in some patients, because the tumor is lower down in their stomach, they may not have very many symptoms, because there’s a lot more give in this muscular bag that our stomach is.  

And so we test the endoscopic ultrasound to look at the depth of an invasion and also other X-ray type imaging such as a PET scan, a P-E-T scan or a CAT scan, which gives us a sense of tumor location whether or not we think the lymph nodes may be involved. And ultimately the final way to assess, especially in patients who are undergoing surgery, is their microscopic involvement of the lymph nodes? Because that often drives the likelihood of cancer coming back after surgery.  

Katherine:

And how do the stages work for gastric cancer? 

Dr. Janjigian:

So, in gastric cancer it’s either early, intermediate, or late stage. And this goes from stage I to IV. So, stage IV  tumors is where most of the cancers are present. Over probably 50 percent of our patients present already at the time of diagnosis with more advanced stages. 

Biologically this cancer just tends to move quickly. So, even in between endoscopies in patients who get endoscopies frequently, often it goes from 0 to stage III or IV because of the lymph node involvement and also spread of microscopic cells, right? Tiny, tiny cells before we even see them, they spread through the bloodstream to other organs or lymph nodes outside of your abdomen. So, that’s considered to be stage IV. And then early, early stage disease is stage I. Those usually that we can just scoop them out using endoscopic procedures. They don’t even need to have full surgery. And then stage II and III is usually if there’s some involvement of the tumor through the muscle or into the muscle of the stomach and also some lymph node involvement. But that’s how we stage it.  

Katherine:

Okay. I’d like to move onto current gastric cancer treatment options. Can you provide an overview of what’s available now?  

Dr. Janjigian:

Right. So, in patients with intermediate or early-stage tumors, really surgery is the main way to cure patients. Occasionally when we have an amazing response to chemotherapy or chemotherapy with immunotherapy or just immunotherapy, we can avoid surgery. But in most patients, surgery in early-stage disease is a gold standard for cure. Of course, it can be a very jarring thing to say to someone. “We have to take out. your stomach.” But patients do live without either fully their stomach removed or partially removed. And that’s the gold standard. We do additionally other treatments to help maximize chances of cure, but surgery is the main state. As I mentioned earlier, most of our patients, however, present with later stages where surgery is not feasible.  

And when I say it’s not feasible, we would only attempt an operation if we thought there was a possibility of removing the cancer completely. Leaving some of the tumor behind, even if it’s only 1 percent of the cancer behind, makes patients unwell. They may not be able to tolerate additional chemo, so we do not recommend doing suboptimal surgery unless cancer can be completely removed. So, in those patients, we always explain the situation. And the disease is not potentially as curable, but it’s absolutely always treatable. And since the development of our immunotherapy options, really, we’ve changed the trajectory and the course of those cancers. We won’t know the stage or the final response to therapy until we’ve start it. But in those patients, usually a form of long-term therapy. Chronic treatment is very important.  

And usually it involves a combination of chemotherapy and some targeted agents, biologic agents, meaning that they were designed in the lab to target the cancer specifically. And usually, they involve some sort of immunotherapy.  

Katherine:

Excuse me. Can you go into some detail about the targeted therapies and immunotherapies that you use?  

Dr. Janjigian:

Sure. So, conventional chemotherapy works on any rapidly dividing cell. And these are chemotherapies that have been tried and true in the clinic for decades, right? And they work still in gastric. And in  particular they’re very important. And then over the last 10 years or so, we’ve started developing target agents in the lab that target the specific biologic tumor biomarkers. And when you think about tumor biomarkers, I would think about them as almost ZIP codes, right? How do you direct the cancer cell to die? 

And how do you inhibit the cancer cell for the thing that is uniquely what’s making it grow as opposed to normal cells, right? So, that’s the difference between chemotherapy because chemotherapy can affect any rapidly dividing normal cell and cancer cell, while biologic agents ideally only affect the target, cancer, the cell. So, that’s why it’s very appealing to do both to help maximize response and survival on treatment. So, the biologic therapies that are available in and already approved in our disease for stomach cancer are something called HER2 directed treatments. And that’s been my focus in the lab. And then in my group has really spearheaded a lot of this research for HER2-positive tumors. In gastric cancer it occurs in up to 20 to 30 percent of tumors, but we have drugs such as trastuzumab or Herceptin, T-DXd, trastuzumab deruxtecan-nxki (Enhertu) or in HER2 that target these agents.  

And furthermore, our work here at Memorial Sloan Kettering demonstrated the combination therapies really for HER2-positive disease has helped improve outcomes in those patients. So, that’s biologic therapy. Other biologic therapies that’s approved in gastric cancer is something called VEGFR-2 inhibitor. These are drugs that target blood vessel formation around the tumor to help the chemotherapy drugs work well and better. Those drugs are called ramucirumab or Cyramza. And that’s used in a combination of chemotherapy in second-line treatment. And there’s other drugs such as regorafenib (Stivarga) and other inhibitors that maybe have some targetable activity in our disease. And last but not the least is immunotherapy. So, immunotherapy’s a completely different class of drugs.  

We think about immunotherapies, really the fundamental problem with cancer, right? The cancer issues that it started as a normal cell. So, at some point, it was a normal cell that then became and went awry and went rogue. And the body did not recognize that there was a problem. And the immune system did not eliminate that cancer cell. Before it started to metastasize and give us problems in their body, right? So, the fundamental question is why is the body’s immune system, why did it not recognize it as a abnormal cell? Well, because it really acts and looks like a normal cell from the immune perspective. Our immune system is trained not to hurt us, right? And that’s why in patients with rheumatoid arthritis or other autoimmune disorders, what happens is the immune system goes awry. So, what the immune checkpoint blockade or immunotherapy for cancer does, is it helps take some of those brakes off our immune system and help our immune system recognize the cancer and give it permission to say, “Hey, you know what?  

You thought it was a normal cell. It’s not. It’s a cancer cell. Please help us eliminate it.” And that’s worked well because I think in for some of our patients, the immune system actually knows how to target and suppress the cancer much better than any of the fancy drugs we can design in the lab. And that’s why in some patients, immune checkpoint blockade immunotherapy has been such a game changer if you do respond, your duration and durability of response is so much more better than anything that would go to just done on our own in the lab or with other chemotherapies. So, it really is a nice way to think about it. And the patients feel like they’re part of the solutions. It’s always nice for them to have that.  

But it’s been a real game changer for both HER2-positive and HER2-negative disease in combination with chemotherapy. I’ve had the pleasure of leading some of these studies. And it’s nice to be able to update the three or the four or the five-year survival rate from these studies in a disease where in the past most patients died within a year.   

Katherine:

Dr. Janjigian, I’d like to talk about what goes into deciding on a best treatment for a patient. Is there testing that helps you understand a patient’s individual disease? 

Dr. Janjigian:

One is an important factor about this disease, and when the patient comes in, the number one factor that helps us decide, what treatment to assign, is how well is the patient feeling? What are their nutritional deficits? How functional they are. Are they able to tolerate the treatment?

Because as an oncologist, the first rule is do no harm. Most patients come in when they’re first diagnosed are pretty well functional. They’re still able to eat. And so, they’re really up for the most aggressive. And that’s probably the number one wish I have from patients. I just want us to stay well and stay alive. So, we can be very aggressive with them, at least folks that come to see us in New York. And so, then the decision fork is really do you want only standard therapy, or are you interested in clinical trials? And I think what I am able to really explain to the patients, which is great, is that the benefit of trials – and, of course, you can never guarantee that a trial will be successful, right? Because that’s by definition – a clinical trial is experimental therapy. But for gastric cancer and stomach cancer where we need as many treatment options as possible, a clinical trial gives you an opportunity to try something different, and then go back to standard therapy, and then try experimental therapy, and then go back to standard therapy.  

So, it gives you as many options as possible. The way that I help our patients visualize this is you’re trying to cross a very wide and somewhat turbulent river. And you need as many stepping stones as possible. And a clinical trial, if it makes sense for you and if you’re able to do it physically, it gives you that other option. The most important other factor is to understand which subset of stomach cancer you have, right? Because biomarker testing has helped us tremendously to advance this disease. If you look at and if you watch any of my talks, I usually have this timeline of therapeutic development in stomach cancer until really this past year.  

We’re 2022, 2021. There was over a decade of negative trials, right? And the reason why I think is because the design of the trial really focused on targeting all the patients the same way. And now the trials are becoming more and more sophisticated. So, when we talk about the biomarker testing of the tumor, the patient’s specific tumor.  

It’s important for the patient to ask their physician. “What is the status of my tumor?” And the four critical biomarkers are microsatellite instability, HER2, PD-L1, and Claudin-18.2. So, those four biomarkers have really helped us transform this field especially in patients with metastatic disease. And in all of the tertiary cancer centers, certainly here at Memorial Sloan Kettering,  for each of the subsets we have a full research portfolio.  

So the patients have both standard and experimental options available to them.             

Katherine:

Well, how can test results like biomarker testing affect the patient’s prognosis and treatment options? 

Dr. Janjigian:

It will depend on the treatment and how it is paired to the biomarkers. So, for example, a certain subset of tumors such as microsatellite and stable tumors are patients with PD-L1 high tumors or even patients with HER2-positive tumors. Now in clinical trials, we see that those patients have an outstanding dramatic response to combination therapies often with chemotherapy or immunotherapy together or even HER2 directed therapy with immunity therapy. So, it really will impact how likely your tumor is to shrink. And if the tumor is shrinking, and if you’re feeling better, obviously that translates to better survival.  

Katherine:

Yeah. What questions should patients be asking about their test results? 

Dr. Janjigian:

I think it’s important for patients to be very clear with their providers about their willingness to undergo repeated biopsies if needed.  

I think the number one misunderstanding or misnomer that I see when patients come in to see me as a highly trained specialists, and they’re seeking me out for expertise and second and third and fourth opinions is that when the biomarker test is not done, often the answer in the community from the physician was, “Well, there was insufficient tissue or the tissue quality was not great, and that’s we’re going to do it. And it turns out the patient is perfectly willing and able to undergo a second biopsy. They really do not mind because a lot of times it’s just as simple as having a repeat endoscopy. Or even on treatment off and the problem is it’s a constantly evolving cancer. So, for example, if you receive first-line treatment and then you progressed and you need additional treatment, often it’s important to get a second biopsy to understand what your biomarkers are at that point. 

And I described this to my patients. We can’t get into a battle with outdated maps. We need to know. And sometimes when there’s a misunderstanding, the doctors think, “Maybe the patient wouldn’t be willing to do it. Or they are risk-averse.” And the patient’s more than willing to do it. So, I think communicating your wishes and your intent clearly with your doctors and not being shy to ask questions, and also not being shy to seek out clinical trials, right? So, yesterday I was in clinic. I see a lot of this disease. I often see 30 patients at clinic. I had an 80-year-old patient in my clinic, right? And before you meet the patient, most doctors would think, “Well, it’s an elderly patient. They wouldn’t even be interested in clinical trials. What are we trying to accomplish here?” 

Katherine:

Right.  

Dr. Janjigian:

But this patient clearly is – he exercises five days a week. He’s extremely active. He wants the best options for him.  

So, I am not an ageist, so I asked him. I said, “What are your sort of goals of this therapy? And how interested are you in clinical trials?” And him and the family were extremely enthusiastic. And, “We’re going to go for it, and we’re going to try.” So, I think having those conversations with your doctors – because you remember gastric cancer is very rare. In my clinic I see 30 patients, but in most normal sort of oncology practices, it’s lung, breast, and colon, the big three that sort of saturate the schedule of the oncologists. So, if they see one or two gastric cancers a month, they may not be thinking along the same lines of your disease. So, then you have to ask the questions of, “Are there any clinical trials? Should I see a specialist?” Did you do all of my biomarkers? 

Katherine:

Yeah, yeah. That’s really great information to have.  

Are there other decision factors involved in deciding on treatment options? You mentioned age, comorbidities. What else do you look at? 

Dr. Janjigian:

Yeah, the other important factor as I said is nutrition. Being able to stay fit and stay independent is very important. Some of my patients ask me, and then they feel like what they eat is so important that as soon as they get their diagnosis, they restrict their diet. And then they start losing weight. And that’s not good. The number one negative prognostic factor is if you lose more than 10 percent of your body weight within the first few months of the diagnosis – because you get really weak, and then you can’t tolerate the chemotherapy. So, I tell the patients, “Your body will take from you whatever it wants. The cancer will take from you, from your body. So, you need to support yourself nutritionally.” So, if you don’t feel like eating a salad, but you are craving a cookie, it’s okay.  

Have that cookie; just don’t lose weight. And I think that’s the number one. And also, the other factor is how do you communicate your diagnosis and your prognosis to your family and your friends? Because then everybody’s asking and making you in some ways anxious, your job. And what I tell patients is, “It’s on need-to-know basis.” If you find love and support, then you can tell people. Otherwise, you can just loosely kind of mention that you need some help, and you’re going through treatment without specific details. And the great part about these combination immunotherapies is that a lot of our functional patients actually continue to work through this. And so, we fill out whatever forms they need for their jobs and so forth. But we have lawyers that are continuing to work, teachers, and sometimes even construction workers. So, really, I would say make decisions as they come up.  

Don’t run too far ahead and sort of assume that you’re going to not be well. But if you want to take some time off, that’s okay too. And so, I think the treatment paradigm for this disease has evolved so much that there’s a lot of misconceptions. And I think the job of a good oncologist is to let the patient live their life in as normal a fashion as possible. So, we work the chemo schedules around their schedule. Some of these immunotherapies you can give once a month. So, I have patients who will fly into see me, for example, get the dose, and then go back home. So, I think don’t be afraid to ask for what you need.  

Katherine:

Yeah. Well, that leads us very smoothly into self-advocacy. And it’s really important that patients advocate for themselves. So, if a patient has a question or they’re unsure about a decision, why is it so important for them to speak up?  

Dr. Janjigian:

What I always tell my patients and I explain to them, that often the doctors know a lot of information. But there’s so much information that it’s almost impossible to – and we only have 15 to 20 minutes together. So, it’s almost impossible to communicate everything that we know to you. So, you need to drive a bit of what the focus is of priorities in each visit and get as much information as you can. But also in some ways, follow the doctor’s lead. So, it’s a balance of information exchange. Use the portal as much as possible as well. The patient portal is often for follow-up questions. Write questions down. We have our nurse practitioners, our nurses, our fellows that continue to educate the patients because as things come up, and the field is so complicated that there  are just so many things that you can ask at one single appointment.  

So, it’s okay to forget something, but just write it down. In the end like anything else, you only have one sort of chance to do this in a way that you want it to be done. And as treatment progresses and you’re not feeling well, and maybe you don’t want to keep coming in for appointments and would rather go spend time in Aruba or Florida or somewhere sunny as opposed to – that’s okay. I think a lot of times it’s your life. You only have one. And I strongly believe in anything to try to get as much out of every interaction as possible using all the resources that are available to you.  

Katherine:

Well, I’d like to close today with getting your thoughts on how you feel about the state of gastric cancer care. Are you hopeful about treatment options? 

Dr. Janjigian:

I’m extremely hopeful. And usually, I finish all of my scientific talks. I’m a physician scientist.  

I travel a lot to meetings. And my goal now in my career is to attract more and more young talent and scientists that will help us make the next wave of breakthroughs for this difficult disease. I think we’ve made a lot of progress, but the reality is: We’re still not curing enough patients. And so, our next wave is not just to stabilize and help people live longer but cure them definitively and permanently. And so, I finish every single presentation I have by how much the possibility and how fruitful this field has been. Personally, for my work and career of those that I’ve mentored throughout the years all over the world. So, I’m very hopeful for the next five, 10 years in this field. It will continue to get better.   

Katherine:

It sounds very promising. Dr. Janjigian, thank you so much for joining us today.  

Dr. Janjigian:

Thank you. Great question.

 Katherine:

Hello and welcome. I’m your host, Katherine Banwell. Today’s program focuses on helping patients understand gastric cancer treatment options based on their individual disease. We’ll review the latest research and provide tips for self-advocacy to help patients access better care.  

Before we meet our guest, let’s review a few important details. The reminder email that you received about this webinar contains a link to a program resource guide. If you haven’t already, click that link to access information to follow along during the webinar. At the end of this program, you’ll receive a link to a program survey. Please take a moment to provide feedback about your experience today in order to help us plan future webinars.  

And finally, before we get into the discussion, please remember that this program is not a substitute for seeking medical advice. Please refer to your healthcare team about what might be best for you. Well, let’s meet our guest today. Joining me is Dr. Yelena Janjigian. Dr. Janjigian, welcome. Would you please introduce yourself? 

Dr. Janjigian:

Thank you so much, Katherine, for this opportunity. My name is Yelena Janjigian. I’m a medical oncologist. And I oversee the GI oncology service at Memorial Sloan Kettering Cancer Center in New York. We’re a large group of doctors, over 40 physicians who treat everything from esophagus cancer to rectal cancer. And my research focus and my passion has been in developing new treatments for patients with stomach cancer, so I personally focus on this disease clinically and from research perspective.  

Katherine:

Okay. Lovely.  

Well, thank you so much for joining us today. I’d like to start by learning about the latest research news. Are there recent advances in gastric cancer that patients should know about? 

Dr. Janjigian:

That’s a great question. The field of gastric cancer research has accelerated and evolved immensely over the last three years. We’ve had several important approvals for treatment of metastatic disease both for biomarkers selected population and immunotherapy targeted therapies. So, there’s been a lot of research, a lot of effort and some positive data that the patients and clinicians should be aware of.  

Katherine:

And what excites you about the research you’re involved with? 

Dr. Janjigian:

I’ve been focused on gastric cancer for nearly two decades. So, my recent advances have really helped to understand how we can improve patient’s survival better, potentially cure more patients, and understand the different subsets of cancer treatments and patients with gastric cancer understanding that not all gastric cancer is the same.  

So, I think being able to zoom in on different subsets and target personalized approaches for each individual patient is why I stay in research, why I stay in gastric cancer research because we’ve been able to make some major breakthroughs.  

Katherine:

That’s excellent news. How can patients stay up to date with treatment options? 

Dr. Janjigian:

That’s a great question. And recently there’s been a lot of resources online through both the big pharma really educating patients with patient-friendly handouts. And many of my big recent papers when we publish them in big journals like Lancet or Lancet Oncology, for example, or JCO, there’s always a patient-friendly handout that comes with that data that helps patients understand some of the endpoints, how do we describe why this study is positive? 

Or why is the FDA decided to approve the drug? So, there are many patient handouts that come with some of these papers. And it’s interesting, a lot of my patients come in. When they see me, they say, “Oh, it’s so good to finally meet you. I’ve watched a lot of your videos.” So, because of COVID actually, a lot of the scientific content that used to be just in in-person meetings behind doors for doctors, now it’s all online because a lot of these scientific presentations are now made for virtual content as well. So, patients have access to it. That’s double-edged sometimes. It’s a little bit of an information overload, and it may actually make patients feel more anxious than reassure them, right? Because it’s a lot of jargon and not too – but some patients find it helpful.  

Katherine:

Yeah, I can see that. It can be a double-edged sword.   

Dr. Janjigian:

Yeah.   

Katherine:

Well, thank you for that advice. So, now that we’ve heard what’s happening in research, let’s review some more basic information about gastric cancer. First, gastric cancer is sometimes referred to as stomach cancer. Is that the same thing, or are both terms correct?  

Dr. Janjigian:

Yeah. So, stomach is really where the cancer starts. But we can talk about stomach or abdomen. But gastric and stomach are the same tumor location basically. What’s interesting actually, some patients also have tumors that start at the bottom of their esophagus and extend into the stomach. So, biologically a lot of these cancers behave similarly. In fact, in United States the most common location for these cancers actually is in between the gastric esophageal junction and the stomach.  

So, it’s in the location in of the cancer that’s at the very top of the stomach. But in short, stomach cancer and gastric cancer are interchangeable. And as I mentioned, for many of our viewers, actually gastro-esophageal junction is also part of the same disease.  

Katherine:

Could you tell us what tests are used to diagnose gastric cancer? 

Dr. Janjigian:

Most of our patients, when they come in to see me, by then the diagnosis of cancer has been made because I’m on oncologist.  

In clinical practice, patients often present with vague symptoms or no symptoms at all. And that’s an important point for our clinicians to understand. In patients who have chronic acid reflux or have, for example, other risk factors such as H. pylori infection, often they end up getting endoscopy at the time, for example, for their first colonoscopy. So, the age of colonoscopy, the first colonoscopy has is getting earlier and earlier with each update, because colon cancer is increasing in incidents in younger adults. So, sometimes patients present and get first endoscopy, for example, which is an upper test with a camera when they’re getting their colonoscopies. In other patients, unfortunately, they present with more progressive symptoms. Often, it’s difficulty swallowing, regurgitation of food, and weight loss, which is obviously very dramatic.  

And so they end up getting an endoscopy because of that and referred by their doctors.   

Katherine:

How is gastric cancer staged? And what do the stages mean? 

Dr. Janjigian:

Yeah. So, the most important part of the staging of gastric cancer and what patients ask me, “What is my risk of cancerous recurrence? What is my stage?” Really what it comes down to is the depth of invasion. So, it’s not only the size of the tumor, but how deep is it going into the muscle of the stomach, because stomach and your esophagus are basically a muscular bag, right? And so how deep is the invasion of the tumor into the wall? And also how likely are the lymph nodes to being involved? So, we assess it based on clinical symptoms such as swallowing difficulty and so forth. But in some patients, because the tumor is lower down in their stomach, they may not have very many symptoms, because there’s a lot more give in this muscular bag that our stomach is.  

And so we test the endoscopic ultrasound to look at the depth of an invasion and also other X-ray type imaging such as a PET scan, a P-E-T scan or a CAT scan, which gives us a sense of tumor location whether or not we think the lymph nodes may be involved. And ultimately the final way to assess, especially in patients who are undergoing surgery, is their microscopic involvement of the lymph nodes? Because that often drives the likelihood of cancer coming back after surgery.  

Katherine:

And how do the stages work for gastric cancer? 

Dr. Janjigian:

So, in gastric cancer it’s either early, intermediate, or late stage. And this goes from stage I to IV. So, stage IV  tumors is where most of the cancers are present. Over probably 50 percent of our patients present already at the time of diagnosis with more advanced stages. 

Biologically this cancer just tends to move quickly. So, even in between endoscopies in patients who get endoscopies frequently, often it goes from 0 to stage III or IV because of the lymph node involvement and also spread of microscopic cells, right? Tiny, tiny cells before we even see them, they spread through the bloodstream to other organs or lymph nodes outside of your abdomen. So, that’s considered to be stage IV. And then early, early stage disease is stage I. Those usually that we can just scoop them out using endoscopic procedures. They don’t even need to have full surgery. And then stage II and III is usually if there’s some involvement of the tumor through the muscle or into the muscle of the stomach and also some lymph node involvement. But that’s how we stage it.  

Katherine:

Okay. I’d like to move onto current gastric cancer treatment options. Can you provide an overview of what’s available now?  

Dr. Janjigian:

Right. So, in patients with intermediate or early-stage tumors, really surgery is the main way to cure patients. Occasionally when we have an amazing response to chemotherapy or chemotherapy with immunotherapy or just immunotherapy, we can avoid surgery. But in most patients, surgery in early-stage disease is a gold standard for cure. Of course, it can be a very jarring thing to say to someone. “We have to take out. your stomach.” But patients do live without either fully their stomach removed or partially removed. And that’s the gold standard. We do additionally other treatments to help maximize chances of cure, but surgery is the main state. As I mentioned earlier, most of our patients, however, present with later stages where surgery is not feasible.  

And when I say it’s not feasible, we would only attempt an operation if we thought there was a possibility of removing the cancer completely. Leaving some of the tumor behind, even if it’s only 1 percent of the cancer behind, makes patients unwell. They may not be able to tolerate additional chemo, so we do not recommend doing suboptimal surgery unless cancer can be completely removed. So, in those patients, we always explain the situation. And the disease is not potentially as curable, but it’s absolutely always treatable. And since the development of our immunotherapy options, really, we’ve changed the trajectory and the course of those cancers. We won’t know the stage or the final response to therapy until we’ve start it. But in those patients, usually a form of long-term therapy. Chronic treatment is very important.  

And usually it involves a combination of chemotherapy and some targeted agents, biologic agents, meaning that they were designed in the lab to target the cancer specifically. And usually, they involve some sort of immunotherapy.  

Katherine:

Excuse me. Can you go into some detail about the targeted therapies and immunotherapies that you use?  

Dr. Janjigian:

Sure. So, conventional chemotherapy works on any rapidly dividing cell. And these are chemotherapies that have been tried and true in the clinic for decades, right? And they work still in gastric. And in  particular they’re very important. And then over the last 10 years or so, we’ve started developing target agents in the lab that target the specific biologic tumor biomarkers. And when you think about tumor biomarkers, I would think about them as almost ZIP codes, right? How do you direct the cancer cell to die? 

And how do you inhibit the cancer cell for the thing that is uniquely what’s making it grow as opposed to normal cells, right? So, that’s the difference between chemotherapy because chemotherapy can affect any rapidly dividing normal cell and cancer cell, while biologic agents ideally only affect the target, cancer, the cell. So, that’s why it’s very appealing to do both to help maximize response and survival on treatment. So, the biologic therapies that are available in and already approved in our disease for stomach cancer are something called HER2 directed treatments. And that’s been my focus in the lab. And then in my group has really spearheaded a lot of this research for HER2-positive tumors. In gastric cancer it occurs in up to 20 to 30 percent of tumors, but we have drugs such as trastuzumab or Herceptin, T-DXd, trastuzumab deruxtecan-nxki (Enhertu) or in HER2 that target these agents.  

And furthermore, our work here at Memorial Sloan Kettering demonstrated the combination therapies really for HER2-positive disease has helped improve outcomes in those patients. So, that’s biologic therapy. Other biologic therapies that’s approved in gastric cancer is something called VEGFR-2 inhibitor. These are drugs that target blood vessel formation around the tumor to help the chemotherapy drugs work well and better. Those drugs are called ramucirumab or Cyramza. And that’s used in a combination of chemotherapy in second-line treatment. And there’s other drugs such as regorafenib (Stivarga) and other inhibitors that maybe have some targetable activity in our disease. And last but not the least is immunotherapy. So, immunotherapy’s a completely different class of drugs.  

We think about immunotherapies, really the fundamental problem with cancer, right? The cancer issues that it started as a normal cell. So, at some point, it was a normal cell that then became and went awry and went rogue. And the body did not recognize that there was a problem. And the immune system did not eliminate that cancer cell. Before it started to metastasize and give us problems in their body, right? So, the fundamental question is why is the body’s immune system, why did it not recognize it as a abnormal cell? Well, because it really acts and looks like a normal cell from the immune perspective. Our immune system is trained not to hurt us, right? And that’s why in patients with rheumatoid arthritis or other autoimmune disorders, what happens is the immune system goes awry. So, what the immune checkpoint blockade or immunotherapy for cancer does, is it helps take some of those brakes off our immune system and help our immune system recognize the cancer and give it permission to say, “Hey, you know what?  

You thought it was a normal cell. It’s not. It’s a cancer cell. Please help us eliminate it.” And that’s worked well because I think in for some of our patients, the immune system actually knows how to target and suppress the cancer much better than any of the fancy drugs we can design in the lab. And that’s why in some patients, immune checkpoint blockade immunotherapy has been such a game changer if you do respond, your duration and durability of response is so much more better than anything that would go to just done on our own in the lab or with other chemotherapies. So, it really is a nice way to think about it. And the patients feel like they’re part of the solutions. It’s always nice for them to have that.  

But it’s been a real game changer for both HER2-positive and HER2-negative disease in combination with chemotherapy. I’ve had the pleasure of leading some of these studies. And it’s nice to be able to update the three or the four or the five-year survival rate from these studies in a disease where in the past most patients died within a year.   

Katherine:

Dr. Janjigian, I’d like to talk about what goes into deciding on a best treatment for a patient. Is there testing that helps you understand a patient’s individual disease? 

Dr. Janjigian:

One is an important factor about this disease, and when the patient comes in, the number one factor that helps us decide, what treatment to assign, is how well is the patient feeling? What are their nutritional deficits? How functional they are. Are they able to tolerate the treatment?

Because as an oncologist, the first rule is do no harm. Most patients come in when they’re first diagnosed are pretty well functional. They’re still able to eat. And so, they’re really up for the most aggressive. And that’s probably the number one wish I have from patients. I just want us to stay well and stay alive. So, we can be very aggressive with them, at least folks that come to see us in New York. And so, then the decision fork is really do you want only standard therapy, or are you interested in clinical trials? And I think what I am able to really explain to the patients, which is great, is that the benefit of trials – and, of course, you can never guarantee that a trial will be successful, right? Because that’s by definition – a clinical trial is experimental therapy. But for gastric cancer and stomach cancer where we need as many treatment options as possible, a clinical trial gives you an opportunity to try something different, and then go back to standard therapy, and then try experimental therapy, and then go back to standard therapy.  

So, it gives you as many options as possible. The way that I help our patients visualize this is you’re trying to cross a very wide and somewhat turbulent river. And you need as many stepping stones as possible. And a clinical trial, if it makes sense for you and if you’re able to do it physically, it gives you that other option. The most important other factor is to understand which subset of stomach cancer you have, right? Because biomarker testing has helped us tremendously to advance this disease. If you look at and if you watch any of my talks, I usually have this timeline of therapeutic development in stomach cancer until really this past year.  

We’re 2022, 2021. There was over a decade of negative trials, right? And the reason why I think is because the design of the trial really focused on targeting all the patients the same way. And now the trials are becoming more and more sophisticated. So, when we talk about the biomarker testing of the tumor, the patient’s specific tumor.  

It’s important for the patient to ask their physician. “What is the status of my tumor?” And the four critical biomarkers are microsatellite instability, HER2, PD-L1, and Claudin-18.2. So, those four biomarkers have really helped us transform this field especially in patients with metastatic disease. And in all of the tertiary cancer centers, certainly here at Memorial Sloan Kettering,  for each of the subsets we have a full research portfolio.  

So the patients have both standard and experimental options available to them.             

Katherine:

Well, how can test results like biomarker testing affect the patient’s prognosis and treatment options? 

Dr. Janjigian:

It will depend on the treatment and how it is paired to the biomarkers. So, for example, a certain subset of tumors such as microsatellite and stable tumors are patients with PD-L1 high tumors or even patients with HER2-positive tumors. Now in clinical trials, we see that those patients have an outstanding dramatic response to combination therapies often with chemotherapy or immunotherapy together or even HER2 directed therapy with immunity therapy. So, it really will impact how likely your tumor is to shrink. And if the tumor is shrinking, and if you’re feeling better, obviously that translates to better survival.  

Katherine:

Yeah. What questions should patients be asking about their test results? 

Dr. Janjigian:

I think it’s important for patients to be very clear with their providers about their willingness to undergo repeated biopsies if needed.  

I think the number one misunderstanding or misnomer that I see when patients come in to see me as a highly trained specialists, and they’re seeking me out for expertise and second and third and fourth opinions is that when the biomarker test is not done, often the answer in the community from the physician was, “Well, there was insufficient tissue or the tissue quality was not great, and that’s we’re going to do it. And it turns out the patient is perfectly willing and able to undergo a second biopsy. They really do not mind because a lot of times it’s just as simple as having a repeat endoscopy. Or even on treatment off and the problem is it’s a constantly evolving cancer. So, for example, if you receive first-line treatment and then you progressed and you need additional treatment, often it’s important to get a second biopsy to understand what your biomarkers are at that point. 

And I described this to my patients. We can’t get into a battle with outdated maps. We need to know. And sometimes when there’s a misunderstanding, the doctors think, “Maybe the patient wouldn’t be willing to do it. Or they are risk-averse.” And the patient’s more than willing to do it. So, I think communicating your wishes and your intent clearly with your doctors and not being shy to ask questions, and also not being shy to seek out clinical trials, right? So, yesterday I was in clinic. I see a lot of this disease. I often see 30 patients at clinic. I had an 80-year-old patient in my clinic, right? And before you meet the patient, most doctors would think, “Well, it’s an elderly patient. They wouldn’t even be interested in clinical trials. What are we trying to accomplish here?” 

Katherine:

Right.  

Dr. Janjigian:

But this patient clearly is – he exercises five days a week. He’s extremely active. He wants the best options for him.  

So, I am not an ageist, so I asked him. I said, “What are your sort of goals of this therapy? And how interested are you in clinical trials?” And him and the family were extremely enthusiastic. And, “We’re going to go for it, and we’re going to try.” So, I think having those conversations with your doctors – because you remember gastric cancer is very rare. In my clinic I see 30 patients, but in most normal sort of oncology practices, it’s lung, breast, and colon, the big three that sort of saturate the schedule of the oncologists. So, if they see one or two gastric cancers a month, they may not be thinking along the same lines of your disease. So, then you have to ask the questions of, “Are there any clinical trials? Should I see a specialist?” Did you do all of my biomarkers? 

Katherine:

Yeah, yeah. That’s really great information to have.  

Are there other decision factors involved in deciding on treatment options? You mentioned age, comorbidities. What else do you look at? 

Dr. Janjigian:

Yeah, the other important factor as I said is nutrition. Being able to stay fit and stay independent is very important. Some of my patients ask me, and then they feel like what they eat is so important that as soon as they get their diagnosis, they restrict their diet. And then they start losing weight. And that’s not good. The number one negative prognostic factor is if you lose more than 10 percent of your body weight within the first few months of the diagnosis – because you get really weak, and then you can’t tolerate the chemotherapy. So, I tell the patients, “Your body will take from you whatever it wants. The cancer will take from you, from your body. So, you need to support yourself nutritionally.” So, if you don’t feel like eating a salad, but you are craving a cookie, it’s okay.  

Have that cookie; just don’t lose weight. And I think that’s the number one. And also, the other factor is how do you communicate your diagnosis and your prognosis to your family and your friends? Because then everybody’s asking and making you in some ways anxious, your job. And what I tell patients is, “It’s on need-to-know basis.” If you find love and support, then you can tell people. Otherwise, you can just loosely kind of mention that you need some help, and you’re going through treatment without specific details. And the great part about these combination immunotherapies is that a lot of our functional patients actually continue to work through this. And so, we fill out whatever forms they need for their jobs and so forth. But we have lawyers that are continuing to work, teachers, and sometimes even construction workers. So, really, I would say make decisions as they come up.  

Don’t run too far ahead and sort of assume that you’re going to not be well. But if you want to take some time off, that’s okay too. And so, I think the treatment paradigm for this disease has evolved so much that there’s a lot of misconceptions. And I think the job of a good oncologist is to let the patient live their life in as normal a fashion as possible. So, we work the chemo schedules around their schedule. Some of these immunotherapies you can give once a month. So, I have patients who will fly into see me, for example, get the dose, and then go back home. So, I think don’t be afraid to ask for what you need.  

Katherine:

Yeah. Well, that leads us very smoothly into self-advocacy. And it’s really important that patients advocate for themselves. So, if a patient has a question or they’re unsure about a decision, why is it so important for them to speak up?  

Dr. Janjigian:

What I always tell my patients and I explain to them, that often the doctors know a lot of information. But there’s so much information that it’s almost impossible to – and we only have 15 to 20 minutes together. So, it’s almost impossible to communicate everything that we know to you. So, you need to drive a bit of what the focus is of priorities in each visit and get as much information as you can. But also in some ways, follow the doctor’s lead. So, it’s a balance of information exchange. Use the portal as much as possible as well. The patient portal is often for follow-up questions. Write questions down. We have our nurse practitioners, our nurses, our fellows that continue to educate the patients because as things come up, and the field is so complicated that there  are just so many things that you can ask at one single appointment.  

So, it’s okay to forget something, but just write it down. In the end like anything else, you only have one sort of chance to do this in a way that you want it to be done. And as treatment progresses and you’re not feeling well, and maybe you don’t want to keep coming in for appointments and would rather go spend time in Aruba or Florida or somewhere sunny as opposed to – that’s okay. I think a lot of times it’s your life. You only have one. And I strongly believe in anything to try to get as much out of every interaction as possible using all the resources that are available to you.  

Katherine:

Well, I’d like to close today with getting your thoughts on how you feel about the state of gastric cancer care. Are you hopeful about treatment options? 

Dr. Janjigian:

I’m extremely hopeful. And usually, I finish all of my scientific talks. I’m a physician scientist.  

I travel a lot to meetings. And my goal now in my career is to attract more and more young talent and scientists that will help us make the next wave of breakthroughs for this difficult disease. I think we’ve made a lot of progress, but the reality is: We’re still not curing enough patients. And so, our next wave is not just to stabilize and help people live longer but cure them definitively and permanently. And so, I finish every single presentation I have by how much the possibility and how fruitful this field has been. Personally, for my work and career of those that I’ve mentored throughout the years all over the world. So, I’m very hopeful for the next five, 10 years in this field. It will continue to get better.   

Katherine:

It sounds very promising. Dr. Janjigian, thank you so much for joining us today.

Transcript:

Katherine Banwell:

What are the various subtypes of lung cancer, and how are they identified?  

Dr. Erin Schenk:

Absolutely. So, there are a number of different subtypes of lung cancer that are important for us to identify, because it helps to stratify or helps to select the right treatment approaches for a patient. So, usually when someone is diagnosed with lung cancer there was a scan done at some point that noticed a mass or masses in the body. 

What happens next is a biopsy happens where a needle is used to sample the tissue, and that could be in the lung, that could be in lymph nodes or other parts of the body and that tissue that’s sampled is first sent to my colleagues in pathology.  

And they’re a group of doctors who look at tissues underneath the microscope and try to identify what those are. And based on that initial pathology analysis, we can identify usually pretty straightforward, what is the type of cancer that they see under the microscope.  

And so, in very general terms there are non-small cell lung cancers, there is a group called small cell lung cancers, and there’s also a group called neuroendocrine cancers as well. Oftentimes, times we’re able to differentiate these types of tumors, these types of lung cancers based on how different markers show up, and these are called stains. 

And these stains can differentiate non-small cell between adenocarcinoma versus squamous cell carcinoma. And then they can also help differentiate small cell lung cancer. And then, of course, they can also help to identify if this is a neuroendocrine tumor. 

Katherine Banwell:

Today we’re going to focus on non-small cell lung cancer. Are there specific tests that patients should ask their doctor for following a diagnosis? 

Dr. Erin Schenk:

Absolutely, and I think it’s sometimes helpful to understand what are all the pieces of information I need when I first meet a patient to make decisions about treatments? So, we just went over the histology or another word, the pathology, what does the cancer look like underneath – under the microscope? That can help and that’s one of the pieces, understanding what type of non-small cell lung cancer is present. 

Additional information that’s needed includes certain tests, and you might hear say like, molecular testing or sequencing.  

Those pieces of information can be really important for treatment selection. So, whether there’s a diagnosis of adenocarcinoma or squamous cell lung cancer, we always try to know the PD-L1 status. And that’s actually a surface marker that’s present on the outside of the cancer cells and is able to help us select immunotherapy treatments as appropriate.  

Oftentimes, patients with lung adenocarcinoma will get further sequencing of the tumor itself. And again, you might hear of this called molecular testing or next-generation sequencing, NGS. There are a lot of terms we use for it, but fundamentally, what we’re trying to do is understand the vulnerabilities of the cancer cells. 

And these vulnerabilities can be identified by these molecular tests. They often are able to recognize mutations or fusions or genetic changes within the cancer cells that are present. This is critically important, because we have a whole number of oral targeted therapies that can go after these mutations or alterations, and in other words, they go after the vulnerability in the cancer cells. That’s the adenocarcinoma histology.  

That’s the majority of non-small cell lung cancer diagnoses but I think also if you have been told your diagnosis is of squamous lung cancer, classically we don’t often think of those driver alterations or those fusions or mutations that I just spoke about. But I think it’s also quite important for patients in that situation to also undergo molecular testing.  

As we learn more and more, sometimes those squamous lung cancers can also bear those same alterations. Not to the same frequency, but they can be present, and I think it’s important as you’re thinking about a patient to try to understand what are all the tools I have for them to do that sequencing just to make sure you’re not missing something. So, that’s a really in-depth look to molecular testing.  

I’d like to transition to some of the other tests that would be necessary to help put that molecular testing in context. Another important piece is something called staging.  And staging is a way to determine if the lung cancer has traveled elsewhere in the body. 

Sometimes it can be involved in the lymph nodes of the middle of the chest. Sometimes it can go outside the chest. For example, to the bones or the liver or the brain, and understanding that information, understanding that lay of the land before we start treatment, is really important, not only for treatment selection, like the treatments, the medicines I would give as a medical oncologist.  

But also, in thinking about which other colleagues of mine who help take care of patients with lung cancer should I also involve in some of these treatment decisions. So, staging can often involve CT scans of the chest, abdomen, pelvis. A PET scan can be done. As well as an MRI of the brain. 

Katherine Banwell:

Dr. Schenk, I just want to confirm that you’ve been speaking about molecular testing, that’s the same as biomarker testing, right? 

Dr. Erin Schenk:

Exactly. Exactly. 

Katherine Banwell:

And how is it performed? 

Dr. Erin Schenk:

So, biomarker testing, molecular testing, NGS, there’s a whole range of synonyms we use, that is done primarily on the tumor tissue.  

So, the first test that usually comes back is a marker on the cancer cell. 

That’s PD-L1. That is an IHC test that is able to be done pretty quickly and we’re able to have a turnaround time of just a few days to understand that first biomarker. But the PD-L1 status does not make sense unless we have all of the other information to get the best context, the best understanding of the tumor and what drives the tumor. That additional testing is actually the next-generation sequencing where the genetic material of cancer cells, the DNA and RNA is sequenced in a laboratory to look for those mutations or fusions or other alterations that can drive the cancer cells. And again, it helps me identify additional vulnerabilities in the cancer cells to allow me to pick the optimal therapy for the patient in front of me.  

The tissue testing is the gold standard and we try to get all of our answers from the tissue. Sometimes we’re also able to get additional information from the blood, and that’s what’s called a liquid biopsy. Cancer cells – in some patients, cancer cells shed their genetic material into the bloodstream.  

And these specialized tests are able to pick up that genetic material, have the sequencing done on that, and then report back to me about what may or may not be found.  

Now, as I mentioned, not all of lung cancers shed this information into the blood, so it’s not – if the blood does not reveal an answer or information, that’s – we still need to look closer at the tissue, but occasionally if the blood reveals certain alterations, that can be acted upon, and we don’t have to wait for the tissue testing. 

I think one of the challenges that I absolutely sympathize with their biomarker or molecular testing is that it can take a series of weeks to really get all of the information necessary to make the best choice for the patient in front of us.  

And I have a – I have a saying I like to share with patients that is really important and I think really fundamental to the treatment choices for patients with lung cancer and that is, it’s better to get started on the right treatment rather than the fast one, and that’s true. We know through a series of clinical trials that if I were to start a patient on a treatment that wasn’t appropriate to their biomarkers I actually hurt them. So, I actually reduce how well their later therapies will work. 

And so, it’s a tough wait and I anxiously wait with all of my patients but it’s a really important – it’s really important to get all of that information together. 

Katherine Banwell:

Well, would the cancer change dramatically over a period of three or four weeks?  

Dr. Erin Schenk:

That’s it, you know, that’s a question I hear a lot from patients, and, again, to empathize with the agony of waiting, it’s hard to wait but I can tell you as a doctor who’s taken care of many, many patients with lung cancer the weeks do not make a difference in terms of will have – will it hurt me? So, it will not in general it does not hurt to wait. It’s better to get started on the right treatment because the right treatment has the highest chance of being effective. 

So, the two to three weeks very rarely in my experience has that changed a situation for a patient, but that’s also why we frequently do the liquid biopsy testing at the same time as the tissue testing, because we too want to try to get the answer as quick as possible. So, we try to exhaust all of the routes that we have to get the answer that we need for our patients. 

Katherine Banwell:

What about the latest advances, is there anything in lung cancer testing that patients should know about?  

Dr. Erin Schenk:

Yes, absolutely. I think more and more we’re using these liquid biopsies in different situations for patients with lung cancer. So, Katherine, you and I have mostly been talking about patients who’ve been diagnosed with metastatic disease or a disease that’s been spread outside of the lungs. The liquid biopsy testing, though we’re starting to use in patients who have tumors we can remove with surgery or tumors we can try to cure with a combination of chemotherapy and radiation therapy. 

And we’re using more as a marker of response, and what I mean by that is let’s say someone with a cancer that can be surgically resected or removed by surgery, we can check their liquid biopsy. And if we see a marker in their liquid biopsy, we can then follow that over time in conjunction with scans to try to understand is the cancer – you know, with all the information we can, is the cancer completely gone or are we starting to see that marker again? Do we need to think about doing different scans or different tests to look for a potential area of recurrence of the cancer? 

Katherine Banwell:

What sort of questions should patients be asking about their test results? 

Dr. Erin Schenk:

Uh-huh. I think there are – I think the primary question is “Have you sent my tissue for biomarker testing?” 

And this is true – in my opinion, this is true regardless of the stage of diagnosis, again in the non-small cell lung cancer space, and that’s because we are starting to use some of our targeted therapies as well as our immunotherapies in patients with cancer that can be resected by surgery or maybe would get chemotherapy and radiation therapy. So, these biomarkers are also important in that decision-making for patients that have an earlier stage of disease. And so, I think the first question is, “Has my tissue been sent for biomarker testing?” because I think that’s a part as a necessary part of care given the advances that we’ve made.  

That’s the first question, two, “When do you expect the results? When did it get sent off?” and then three, you know once that has been sent off and whether that’s tissue testing, liquid biopsy, or both, talking with your doctor and your team about what it means.  

How they incorporate this data into your treatment decisions, and then occasionally, asking about did they get all the information they need? Because while we’ve been able to do this biomarker testing for lung cancer for years now, you know, no test is perfect and sometimes cancer cells aren’t the best material to start with when you’re trying to get a really definitive answer.  

So, occasionally patients might need to be biopsied again to really and truly get the full spectrum of information necessary prior to making treatment decisions.

Transcript:

Advances in gastric cancer research are leading to more targeted treatments and giving patients access to personalized care. Personalized medicine – or precision medicine – is a type of care that is based on the genetic makeup and individual characteristics of your disease.  

Biomarker testing identifies key markers such as genes, proteins, or other molecules in a sample of tissue, blood, or other bodily fluid. The test results help the healthcare team better understand your cancer and may influence treatment options – leading to more tailored options with potentially fewer side effects.  

For example, if the PD-L1 receptor is detected during biomarker testing, you may benefit from immunotherapy. The tumor’s HER-2 status or mismatch repair protein expression status may indicate that you may respond well to a targeted therapy. And, treatment targets continue to be identified as research moves forward.  

When deciding on a treatment approach, physicians may consider factors such as: 

  • Your age, overall health, and any pre-existing conditions. 
  • Your type and stage of gastric cancer. 
  • And your test results, including biomarker testing. 

So, how can you partner with your doctor to guide a personalized treatment approach for YOUR gastric cancer? 

  • First, seek a gastric cancer specialist to lead your care. A second opinion consultation with a specialist can confirm your diagnosis and treatment plan. 
  • Ask your doctor if you have had, or will receive, all essential testing, including biomarker testing, and discuss if there are any markers that impact your risk, prognosis, or treatment options.  
  • Inquire about clinical trial options suited to your specific cancer and biomarker test results. 
  • Discuss the potential side effects of each treatment option and ask if any of your existing health conditions may impact your choices. 
  • Include a care partner, such as a friend or loved one – someone you trust – in discussions, so you can feel confident in your decisions.  
  • And finally, always speak up and ask questions. Remember, you have a voice in YOUR gastric cancer care.

Katherine Banwell:

Dr. Strickland, how do biomarker test results impact gastric cancer prognosis?  

Dr. Matthew Strickland:

So, biomarkers will directly guide our treatment decisions in how we can assemble the best treatment plan for our patient as an individual. That will have direct ramifications for how well and for how long that therapy can work for.  

So, I would say that there’s a direct correlation between the biomarker analysis to prognosis.  

Katherine Banwell:

Dr. Strickland, how do biomarker test results impact gastric cancer treatment options?  

Dr. Matthew Strickland:

So, for example, depending on the stage…if a patient has a stage IV cancer, PD-L1 expression will guide our treatment decision whether to include immunotherapy typically with a chemotherapy background or not. To say that a different way, if the expression is very low or absent, we know that patient likely will not benefit from immunotherapy and could actually be harmed, because there is some toxicity that comes with these treatments. That’s one example. But similarly for HER2+ patients, we’ll similarly assemble a treatment regimen with a targeted therapy that is included.  

That certainly guides treatment options, specifically based on a HER2-positive result or negative. The next biomarker I want everyone to know about is called PD-L1. That stands for programmed death ligand 1. This is also a protein that’s expressed on the surface of cancer cells.  

That usually leads to a better outcome than for patients that we can’t include a targeted therapy and left relying on chemotherapy only.  

Katherine Banwell:

Dr. Strickland, what questions should patients ask their healthcare team about testing and test results?  

Dr. Matthew Strickland:

Because biomarker status is so critical for treatment decisions and leading to outcomes and prognosis, I would encourage patients to ask their provider if all standard biomarkers have been obtained at the time of their diagnosis. Sometimes that answer is no, but they’re working on it. That’s okay. But I would highly encourage patients to just ensure that standard biomarkers are being tested for, that they will directly guide the treatment recommendations.  

Katherine Banwell:

Dr. Strickland, is there developing research or treatment news that gastric cancer patients should know about?  

Dr. Matthew Strickland:

I think it’s a very exciting time for the treatment of gastric cancer. Now, we still have a lot of work to do. I don’t want to minimize. This is still a tough and can be an aggressive cancer. It’s no time to let up.   

That being said, if we use immunotherapy as an example alone, there’s been a flurry of new approvals for standard of care in the last three to four years. Our understanding is only increasing of how to select the right patients that will benefit as well as how to avoid some of the toxicities. Beyond immunotherapy, there are new and emerging targets that we can design targeted therapy for.  

We don’t yet have mainstream approvals for targets like Claudin 18.2. But this is a very exciting new target that I think will lead to an approval in the short future.

Katherine Banwell:

Dr. Strickland, what biomarker testing is standard following a gastric cancer diagnosis?  

Dr. Matthew Strickland:

This is a very active area both for approved targets as well as from a research side of things. We’re trying to discover new biomarkers. I think it’s a critically important question. There are really three major biomarkers to help us make conventional treatment decisions. I’ll list them off first. Then, perhaps, I’ll break them down. The first is HER2. That’s H-E-R-2. Typically, folks have heard of this biomarker who are more in the cancer.  

But the truth is that the same molecular alteration happens at a relatively high frequency for gastric cancer. It’s a critically important biomarker because if we determine that the tumor is HER2-positive, what this tells us is that the cancer is thriving based on this protein in the signaling machinery downstream of this protein. The reason we like to know that is we can then target it as a vulnerability of that cancer.  

That certainly guides treatment options, specifically based on a HER2-positive result or negative. The next biomarker I want everyone to know about is called PD-L1. That stands for programmed death ligand 1. This is also a protein that’s expressed on the surface of cancer cells.  

What we’ve come to understand is that high expression of this protein will interact with immune cells in such a way that it tells immune cells to turn the dial down on their activity. From the cancer cell standpoint, this is a very clever mechanism. Because in normal circumstances, our immune system actually can detect cancer and eliminate it to some degree.  

However, when cancer cells choose, if you will, to overexpress this protein on their surface, it can act as a cloak. Suddenly, the immune system can no longer effectively detect and, of course, attack that cancer cell. This is critically important to know because if indeed a cancer cell is using this mechanism to survive, then we can also take advantage of this vulnerability. 

We can add various immunotherapy therapeutics to the treatment plan. The last biomarker of three that I think up front are very important to know about is called mismatch repair status. Mismatch repair proteins are important proteins that we have in all of our cells. Nature basically gave us these proteins to fix small mistakes in the DNA replication.  

That is to say when we’re growing and cells are dividing, DNA, which is the blueprint for our healthy cells, is copied. There’s a very low rate of mistakes, but there is a constant rate of mistakes. So, nature gave us what are called mismatch repair proteins that literally sit on the back of the enzymes that are doing the work.  

They can detect mistakes; they can snip out those mistakes. They can reinsert the right base pairs to fix the proper DNA code. Now, if these proteins are lost or their function is impaired, this can be advantageous to a cancer cell. The reason is mutations and mistakes will pile up, and they don’t get corrected. This can lead to certain growth advantages for the cancer.  

We know that gastric cancer at a relatively high frequency will utilize this mechanism to propagate itself. So, again, by knowing that the cancer is relying on this mechanism, we can directly take advantage of this as a vulnerability. We can improve the outcomes for the patients through their treatment.

Lisa Hatfield:

Dr. Smith, what is the role of immunotherapy or targeted therapy in breast cancer, specifically those whose cancer has relapsed or is in advanced stages?

Dr. Demetria Smith-Graziani:

Currently, we are using immunotherapy mostly for triple-negative breast cancer, for early stage breast cancer, that is not stage IV breast cancer,  we use immunotherapy sometimes in combination with chemotherapy for higher risk, triple-negative breast cancers to help reduce the risk of it coming back in the future.

We also use immunotherapy for metastatic or stage IV triple-negative breast cancer, specifically those cancers that are positive for a protein called PD-L1, we are also doing a number of clinical trials across the country and the world to figure out other situations in which we can use immunotherapy, whether without chemotherapy to treat other types of breast cancer, and my activation tip for patients is ask your oncologist about the standard of care or clinical trial options for the use of immunotherapy for your cancer, and if it would be beneficial to do any testing on your cancer to assess the benefit of immunotherapy.

Expert Perspective | The Value of Empowering Patients

Katherine:

Since no two people with lung cancer are the same, how do you decide which treatment is best for each patient? 

Dr. Patel:

So, the process of evaluating a patient can actually take a little bit of time. So, we first meet a patient, and they may have suspicious findings. We want to understand the full stage of their cancer. And so, in 2022, that’s doing an MRI of the brain, a CT of the chest and abdomen, and often times a pet scan to look for any evidence of distant disease.  

So, once we have radiographic modeling of where we think the tumor is, sometimes we need to do a repeat biopsy to confirm whether or not lymph nodes are involved or the cancer has spread. After we do the biopsy and say that it’s non-small cell lung cancer or small cell lung cancer, we make decisions about looking for genetic markers.  

And so, we’ll often take the tumor tissue and stain for things like PD-L1, which is a marker of response to immunotherapies.  

Very importantly, with all these new targeted therapies, we want to understand the genetic makeup of cancer. So, we want to look for things like EGFR mutations or ALK translocations which are more effectively treated with targeted therapies than chemotherapy or immunotherapy.  

So, those are the tumor characteristics. But, again, I’ve said before, a tumor exists in a person.  

And so, you need to understand what’s important to the person, what do they prioritize, what’s their health like, what, again, are the preferences, are there other comorbidities that could perhaps make some treatments more difficult? Many people, for example, have autoimmune disease. And so, that can be something that’s relatively minor, like some psoriasis that is well-controlled versus perhaps lupus which can cause organ failure.  

Often with psoriasis there are ways that we can give immunotherapy safely. Sometimes other autoimmune diseases would put patients at very high risk with immunotherapies. And so, again, understanding the overall health, understanding other competing causes of toxicity, are absolutely important as you make decisions together.  

Katherine:

Yeah. It seems like we’re getting closer to personalized medicine. For you, how would you define that term? 

Dr. Patel:

Personalized medicine comes in two forms. So, one is the biologics of the tumor itself. So, what do I understand about the genetic markers, the likelihood of response to the available therapies. The other piece, again, is personalizing it to the person that has the cancer.  

And so, again, what are the preferences? What are the risks they’re willing to take? What are their goals? What are the preferences?

Lung Cancer Research Highlights From ASCO 2022

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

How Does Immunotherapy Treat Lung Cancer?


Transcript:

Katherine:

Researchers came together earlier this summer at the annual ASCO meeting. Were there highlights from the meeting that lung cancer patients should know about? 

Dr. Patil:

Right. So, the ASCO ’22 meeting this year had some really interesting publications. So, for me, the key publications that I thought were kind of interesting from ASCO ’22, 2022, one was a publication looking at the role of immunotherapy in patients who are – have a very high PD-L1 expression, so greater than 50 percent. And there’s – 

Katherine:

Reminds us what PDL is. 

Dr. Patil:

Oh, yes, of course. So, PD-L1 is a biomarker. It’s a predictive biomarker that lets us know whether some patients will benefit from immunotherapy. It’s also prognostic because if patients have a high PD-L1 score, they tend to do better with immunotherapy than patients who have a low PD-L1 score. 

Katherine:

Okay.  

Dr. Patil:

Now the interesting data that was presented was a pooled analysis of all the immunotherapy trials to date. And there’s been this ongoing question in lung cancer as to whether patients should get chemo with immunotherapy or whether they should just get immune therapy alone.  

And this study showed that if you have a very high PD-L1 score, it is potentially possible to just use immune therapy and forgo chemotherapy. And I thought that was a very interesting analysis.  

There’s also several other papers that came out as well. Mostly there was a lot of interest in something called circulating tumor DNA. So, let me just take a step back. This is a type of molecule that can be detected in the blood that can help determine whether cancer is present in your blood or not. And there was a lot of publications at ASCO looking at using a concept called minimal residual disease.  

So, when we treat patients with early-stage lung cancer, a big question is how do we know they’re cured or not cured? And a lot of abstracts and publications this ASCO were looking at this concept of minimal residual disease. So, if I can detect some cancer in your blood after you’ve had cured curative therapies, we’re – we have a problem because there’s still cancer around and we’re detecting it in the blood.  

And I think this type of approach is going to really inform how we think about early-stage lung cancer management in the future.

Katherine Banwell:

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

Dr. Estelamari Rodriguez:

So, immunotherapy technically can be used to treat almost every cancer. So, it’s this concept that over time the cancer cells learn to bypass the immune surveillance, which is the way that your body identifies cells that are abnormal and gets rid of them.  

Your immune system can do that. And over time cancer grows and grows faster because your immune cells don’t even recognize that the cancer cells are there. So, immune therapy, specifically the checkpoint inhibitors, they target a receptor that is overexpressed in cancer cells, that make cancer cells invisible to the immune system. So, when you use, for example, some of these antibodies that bind the PD-L1, the programmed death ligand-1 receptor, that in itself gets rid of that veil that is covering the tumor cells. And now, your immune system can recognize the cancer. 

And that is one way of activating the immune system against the cancer, checkpoint inhibitors. There are newer drugs that are coming in the market, newer kind of engineered immune cells that will, in the future, be able to be developed for that specific cell. And in a way, immune therapy is more natural because you’re not getting a chemotherapy is that causes nausea or hair loss.  

You’re getting your immune system kind of ramped up, activated, against your cancer cells. It can have side effects of when you activate all these immune cells, you can cause inflammation in the body that has to be monitored, and some patients can be serious. And also, people have developed autoimmune kind of antibody reactions. So, there is a lot of monitoring that needs to be done. It’s given intravenously. We have doses now that last up to six weeks in some of the major immunotherapies that we use, like pembrolizumab, so you don’t have to come all the time. 

And I think the one thing that I’ve seen that is very promising about immunotherapy is that if you activate your immune system, almost like when you were young you got a vaccine, and you don’t have to get it every year, you have a memory response against that virus. Immunotherapy can achieve that for about 20 to 30 percent of patients today, where they get this memory against the cancer cells, and they could potentially come off treatment.
