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.

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.

Lisa Hatfield:

So, Dr. Brander, how do you explain CLL treatment options and prognosis to your newly diagnosed patients? And I think that the prognosis piece is really important, especially if they do start treatment. 

Dr. Danielle Brander:

What are the things we’re looking for in terms of needing treatment? Because some of those, especially the symptoms we’re noting a lymph node or spleen, for example, or symptoms of anemia, which is low red cells or bleeding from low platelets, it’s helpful for patients to understand what we’re looking for, but, of course, in the time between visits those are the things we want to help patients with if they notice.

And so we encourage them all the time to call our triage or send us, you know, most electronic medical records now, have ways to send your team a message. And we want to know about that from patients in between visits. In terms of prognosis, as I mentioned before, there are other CLL-specific labs usually on the blood, meaning a regular blood draw.

Most patients don’t need another lymph node biopsy or a bone marrow biopsy, though that happens in some cases. And two of those or some of those key markers I mentioned before, but they test in the leukemia, there’s one test called the FISH, F-I-S-H, it’s not specific to CLL, we use it in other cancers. But it’s to look for specific changes in the leukemia genomics, meaning the DNA, the genetic material of the leukemia, not genetics you’re born with, but the cancer itself.

And there are specific patterns and that can be helpful as I sit down with patients to say this isn’t 100 percent, but this is kind of what to expect and likelihood of needing treatment over the next couple of years. There’s another test called IGHV, another mutation test TP53 kind of beyond this to go over right now, but as you mentioned, I think it’s important to meet with your medical team and say, ‘How does this pertain to me specifically?”

In terms of prognosis, I think there’s two parts to that of understanding what to expect. There’s likelihood of needing treatment, there’s likelihood of time to treatment, and those kind of markers and staging system help in a good way. Right now, our historical expectations, meaning 5 or 10 years ago, we could often also sit with patients and say, “This is the prognosis in terms of survival.” Expected life expectancy on average, but in a good way, most of our systems nowadays with the newer treatments likely vastly underestimate patient survival, meaning those systems were designed when we only had chemotherapy treatments.

Now, we know patients even with the highest risk markers, the faster progressions are living, you know, years and years beyond what was expected with chemotherapy. So I just caution especially materials around from just a couple of years ago that likely they don’t pertain, but they can be helpful in knowing what to expect.

How Do Biomarker Test Results Impact a Gastric Cancer Treatment Plan?


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:

So, how is biomarker testing conducted? Is it via a blood test?  

Dr. Matthew Strickland:

This is also an excellent question. Biomarkers can often be tested in different ways. Most of the biomarkers that I’ve outlined start by being tested via cell surface expression of those proteins. Basically, that translates to once the biopsy of the tumor is taken out and is now in the pathology lab, a pathologist can apply different stains to identify these proteins and biomarkers.  

Then, they can assess, in other words, quantify the level of expression. This method is called immunohistochemistry. I would say it’s a fair statement to think this is a first pass method of detecting biomarkers.  

But it’s not the only one. Beyond that…there’s, for example, HER2 can sometimes reflex to assessing the copy number of the gene. So, we’re no longer talking at the protein level. Right now, we’re talking about using a method…the acronym is FISH, which stands for fluorescence in situ hybridization. This is a method to quantify the number of copies of the gene.  

If the cancer has indeed overexpressed HER2 to gain a growth advantage, then often we’ll see a very significantly high copy number. Then, to address your question regarding biomarkers detected in the blood, this is also a new area, relatively new. We know that there are fairly effective tools to test for circulating tumor DNA.   

Backing up for a moment, cancer cells can – let me rephrase. Cancer cells will to some degree shed their DNA into the bloodstream. We are able to detect that unique DNA to some degree. So, these tools, which are generally called circulating tumor DNA assays, there are different companies. The names of their products can be different. But they’re becoming increasingly effective at detecting tumor DNA in the blood.  

So, there are several approvals for these tools. But this can get a little bit tricky. Because the tools are so new, they’re not yet integrated into our standard management. So, perhaps, at larger cancer centers you might see providers utilizing these tools, but it might not be offered at every location.

Donna Catamero:

So, FISH is a cytogenetic technique. So, what we do is, when we do the bone marrow, we send that off and we look at the genetics. Like I said, it’s a snapshot. And certain mutations will put patients in different risk stratifications, so we normally do this at the time of diagnosis and then with each relapse.

In a FISH test, a bone marrow biopsy is taken to map out the genetic material of a cell using fluorescent dyes. These dyes show specific parts of chromosomes and help locate genetic issues like 11;14 translocation, 17 deletion, and others that are important in determining multiple myeloma treatment. If you have not had a FISH test, make sure to ask your doctor if the test should be performed to aid in your diagnosis and treatment.

 

Lisa Hatfield:

The first time I heard FISH test I had no idea what my doctor was talking about. It was actually a nurse practitioner who works with my myeloma specialist who said, “Your FISH test came back, and you have two abnormalities. One of them is called translocation 11;14, standard risk. And one is called monosomy 13, which sometime in the past used to be considered a higher risk but apparently it’s not anymore.” She was trying to explain this to me. I had no idea what she meant what a FISH test was. As time went on and I started to study a little bit more, do a little bit more research on myeloma, I understand the significance and the importance of having a FISH test done for anyone who’s getting diagnosed at a local hospital or community cancer center. I encourage everyone to make sure they can have a FISH test done even if that means consulting with a myeloma specialist to ensure that they can find those cytogenetic abnormalities or to test for those. Because that will help guide your treatment and your prognosis going forward. You want to know what those cytogenetic abnormalities are. They’ll be tracking those over time. So a FISH test is kind of confusing. But without going into too much detail, it’s an interesting test that they can do. It’s very helpful if it’s done at diagnosis. Important to be done at diagnosis,  so those genetic abnormalities can be tracked over time through further testing.

Lisa Hatfield:

So now we’re going to jump into our questions. So, thank you again, Dr. Ailawadhi. So we have a patient asking for newly diagnosed patients, say a patient comes into you, maybe they were sent by their community oncologist or a family practitioner, something…I have myeloma, doesn’t know anything about it. Have even heard of it before. How do you start that conversation? How did you explain myeloma and the treatment and very importantly to the patient, how do you explain the prognosis when you know it’s not curable yet?

Dr. Sikander Ailawadhi:

An extremely important question. And I agree that we should be starting at the beginning, so I think I had the privilege of working at an institution where we tend to spend a lot of face time with the patient, so typically in the outpatient, I have at least about an hour of time blocked is how we’re set up. So at that visit, first of all, I’m hoping that a patient comes in with a caregiver, but if they don’t have a caregiver with them, I start off by asking them, Is there someone they would like us to call during the visit? Because it is always better to have a caregiver or an extra set of ears listening in, and once that has started, then I typically will explain to them literally from what is a plasma cell, what is the role of a normal plasma cell, because that tells us the type of proteins plasma cells produce.

And that leads us to how a plasma cell can become cancerous and lead to multiple myeloma, what are the signs and symptoms of multiple myeloma? What are the markers, these protein markers that come in the blood and are picked up as markers of disease for patients, because again, patients need to know what they’re looking for in the labs that are drawn, so very frequently.

We talked about the role of a bone marrow biopsy, a lot of times it has been done, sometimes it has to be done after that visit, we talk about the genetic mutations in plasma cells that can be seen because that is what helps determine the risk category of standard risk or high risk.

I do offer to patients about discussing the prognosis, again, it’s a good time where we know that the average survival of patients is close to about 8 to 10 years when they look at a general national data, U.S. data, but all the large centers, all of us who focus on myeloma, we have several patients who are living quite a bit in excess of 10 years, so more hopeful time, but it is important to put that prognosis in perspective with high risk or standard risk disease that can be determined based on mutation testing from the plasma cells from the bone marrow, something called the FISH test, part of it is to explain to the patient the prognosis, but other reason is also because sometimes that can determine the type of treatment, and this also importantly tells the patients about their disease much better, so they can be more educated, they can interact with other patients, they can ask the right kind of questions, and they can understand their disease process and follow-up better.

Now, after we have discussed all of this, we start talking about treatment, I can tell you when I talk to a newly diagnosed patient, I will tell them that in my way of thinking their treatment initially is broadly divided into three different discussions during three different visits. The initial visit is talking about any symptom or sign from the myeloma, increased calcium, kidney dysfunction and tumors, how are we going to tackle that? So we will come up with the right “induction regimen.” I really don’t think one-size-fits-all, so based on the patient’s age, comorbidities, other diagnosis or the treatment drugs, family support system, financial situation, there are so many factors that go into it.

We come up with an induction regimen, I’ll tell them that the second component is about controlling all the symptoms and manifestations of the disease, whether that means radiation therapy, bone-strengthening agents, multivitamins, minerals, whatever we need to do as supplements, then we’ll talk about…starting that treatment. What does it involve? Side effects, we will set that path, you will notice I have not even talked about transplant, and I’ll tell the patients that only thing I mentioned to patients in that first planning, visitors and down the road, we will be talking about transplant. Today is not the time, because in my experience at the moment, we start talking about bone matter, transplant tenants, everything was out the window. That’s what patients think about…and I don’t want them to do that.

The second part of my discussion comes around a month or so into the treatment, because by then we want to start seeing some responses, some symptoms turning around, but that month two to three is very importantly the time to rebuild things. Does the patient need to go to physical therapy, pain control? Supportive or palliative care services? Lipoblasty or tuboplasty to strengthen their spine. I mentioned physical therapy, I’ll say it again, because I really think that’s very, very, very important for controlling the pain and supporting the movement and quality of life, managing any side effects, making sure that the dose is correct, do we need to tweak the doses, etcetera. And at that visit is tell them that, “Okay, very soon we will be talking about…we’ll be going into the details of a transplant, we will be passing along more information to you. But at your next visit, which would be probably at that two- to three-month mark, two- to three-cycle mark,” is when I will really sit and talk to them about our transplant…

So for me, the main transplant discussion comes on that cycle to recycle the two to three seconds have already got in patients feeling better, they are much more receptive for the next phase of treatment, which is when we talk about transplant, that’s how I do it, typically. And then we’ll explain a lot about what this transplant need…what does it involve? Caregiver needs a supportive care, vital organ testing, bone marrow biopsy, response depth, MRD, all of that.

So for me, this is kind of the journey that a patient, newly diagnosed patient goes through for the first few months, then their transplant, then their maintenance and hopefully good long disease control state.

Lisa Hatfield:

Great, how often do you expect a patient will have to have appointments during that…talk about the induction phase, the first month to three months, how often do you think they will have appointments, whether it’s for treatment or to come see you? What should they expect that way?

Dr. Sikander Ailawadhi: 

Sure, so the regimens that we typically use in myeloma, some of them, the drugs are given twice a week, a majority of the way we give the drugs, it’s once a week, so one to two times a week would be visits, we do the labs for the first month, we will do sometimes every week, but by the time the patient has gone to the second or third cycle, once every two to four weeks, labs are reasonable because by then things have stabilized, but the treatment still would, I think the once or twice every week depending upon the regimen that they have, we don’t typically see the patient for a clinic appointment every time, but a lot of centers do, so every time the patient comes, as I said, one to two times a week, typically that translates to about four visits in every three to four weeks they coming on the cycle, some regiments are three weeks regiments, some regiments are four week regiments, etcetera.

So patients come, I can say that the first one to two months are most intensive for follow-up for labs, we wanna make sure everything’s been fine, been start reading the treatment, they are not having side effects it and etcetera, and then things can be spaced out a little bit for the next couple of months before we go into the transplant thing, if the patient is going for transplant.

Transcript:

Katherine Banwell:

Dr. O’Donnell, let’s move on to testing. What tests are necessary to help understand a patient’s specific disease? 

Dr. Betsy O’Donnell:

Absolutely. So, testing really does depend a little bit on the stage at which your disease is found. In general, we use a very specific blood test that lets us know that there is clonal protein present. Remember, plasma cells are a type of white blood cell, and they make something called antibodies. We use a test called a serum protein electrophoresis, which is a blood test – an SPEP, we call it – that can tell us the difference between normal, healthy antibody and clone that are made from the plasma cells that we see in MGUS, smoldering, and multiple myeloma. 

So, that’s a very important test, and sometimes your primary care doctor may notice that your total protein is elevated and send that test. 

Or there may be other things that tip them off. Perhaps the kidneys are not where they used to be. And so that test is sent, and that’s the first tip-off that someone might have a plasma cell disorder.  

Once we identify that there’s a plasma cell disorder, then that can set in place a workup, depending on the amount of clonal, monoclonal, M-protein that we see. So, sometimes that involves bone imaging. Historically that was a skeletal survey where we took lots of X-rays of your body. Now we have other tests we use. PET scans, CT scans, whole body MRIs. Sometimes it depends where you’re getting your treatment, and also it depends a little bit on your doctor’s degree of suspicion.  

Bone marrow biopsies are a procedure that we sometimes do. We use a thin, hollow needle to take out just a little piece of bone, about the size of an inchworm, and take some fluid with it. There’s actually fluid inside the bone marrow.  

And that can tell us, just as Dr. Ghobrial was defining the spectrum of plasma cell disorders, based on the percent of plasma cells, that can tell us where somebody belongs, which group they might belong in. So, we can use all of these tests to help give us a good sense of how much disease someone has and where in the spectrum or continuum a person is – MGUS, smoldering, or multiple myeloma. 

Katherine Banwell:

Okay, great. Thank you. I’m assuming these tests can help with understanding the stage of a patient’s myeloma. So, Dr. Nadeem, how is myeloma staged? 

Dr. Omar Nadeem:

Yes. So, myeloma is staged very differently than traditional cancers. Because this is a blood disease, we don’t really think about it like we may in other solid tumor cancers, where if it’s spread to multiple locations it’s IV, etcetera. That doesn’t apply to multiple myeloma. It’s actually staged out of three stages, and uses your blood work for the most part, some blood tests, to help identify which stage you are. Historically, that has correlated with how you may do. 

However, now we are learning that it’s far more to this story than just the blood work. So, we’re now using our bone marrow test results, particularly a test called a FISH test, which looks at the mutations that are present in examinable plasma cells, and if you have presence of some of these high-risk markers, that can actually either upstage you or downstage you if you don’t.  

So, we’re now I think becoming a little bit smarter how we think about this disease. It’s not just based on some blood test. We’re actually looking at the biology of some of these cells and the amount in the bone marrow. A lot of times patients ask, “Well, if I have 50 percent, 60 percent, or 80 percent involvement of the bone marrow, that actually does not have anything to do with staging, right?” So, I think it’s important to know that it’s actually a very unique staging system in multiple myeloma.  

Katherine Banwell:

Okay. Dr. O’Donnell, the landscape of myeloma has changed significantly in recent years. How have advances in testing changed care from myeloma patients?

Dr. Betsy O’Donnell:

So, I mean, the landscape has changed incredibly just in terms of the treatments we have, and I think that Dr. Nadeem was talking about something really important. 

In that when we look at FISH, which allows us to know the biology a little bit more, sometimes it helps us to decide kind of the risk that a patient is. We aren’t really at the point now where we do truly tailored therapies, like you see in some cancers, where we can detect specific mutations and pick drugs that align with that, but there are some that we do use. An example would be a drug called venetoclax (Venclexta), which works very well in patients who have a specific translocation, 11;14. 

So, there is some degree in which we use that FISH and those cytogenetics to help define our treatments, but also really we’re just fortunate that we have new and evolving therapies. We’ve changed how we treat myeloma in the up-front setting, and then at the back end we have an exploding field of immunotherapies, CAR-T cells, bispecific antibody that we’re now using that really have tremendously benefited our patients.  

Katherine Banwell:

Dr. O’Donnell, should all patients undergo in-depth testing, like cytogenetics?  

Dr. Betsy O’Donnell:

Yes, so if you’re doing a bone marrow biopsy, absolutely. The question in terms of who needs bone marrow biopsies, if someone has a low risk MGUS, those patients don’t necessarily require a bone marrow biopsy. It’s an invasive procedure, it’s an uncomfortable procedure. But if we’re doing a workup for multiple myeloma or smoldering myeloma that includes a bone marrow biopsy, then absolutely. 

Katherine Banwell:

Okay. Dr. Nadeem, what are you looking for with cytogenetics, and how might test results affect prognosis and treatment? 

Dr. Omar Nadeem:

Yes, so as mentioned earlier, there are some mutations that are considered high risk, I will say with the caveat that we don’t fully understand every single mutation yet or have identified every single mutation yet that may be high risk or low risk.  

But there are roughly five that we have identified that if a patient has one or two or several of those abnormalities, then their disease may behave a little bit more aggressively or may not respond as well to treatment. 

However, I think myeloma is just very complicated, so we look at a lot of these results in the beginning, both whether they may be good or bad. But I think, ultimately, we have to see how patients do, and that by far is the most important prognostic factor, in my opinion. So, if we look at some of these tools, including staging, some of the bone marrow results and cytogenetics, and try to give some prediction in terms of what we may see from this person’s disease, but ultimately the treatments that are so effective now really dictate the course for the majority of the patients. 

Katherine Banwell:

Are there specific tests that patients should ask for that could impact their care decisions? 

Dr. Omar Nadeem:

Yes, I think it depends on where they are in their disease state. So, if we’re looking at whether a patient has a precursor or plasma cell disorder or multiple myeloma, then they need all the testing to help us figure that out. 

So, that includes a bone marrow biopsy, the FISH testing as we just talked about. Advanced imaging like a PET scan or an MRI is now critical to identify patients that may have multiple myeloma versus those that have a precursor condition. So, we used to count on X-rays, as Dr. O’Donnell mentioned, but now really we do prefer one of those advanced imaging techniques for patients to undergo so that we can know. 

So, I think if they have basically those tests completed, that gives us most of the information that we need.

Should DLBCL Patients Consider a Second Opinion?


Transcript:

Laura Beth:

Dr. Winter, why do you think it’s important for patients to be empowered in their DLBCL care?  

Dr. Winter:

You know, a patient who is, I like the word “engaged” as well as “empowered.” I think it’s important for patients to be empowered or engaged because medicine is very complicated and very fragmented these days.  

Now, it’s so difficult to be a patient and to be sick and not be able to really take control. So, patients need to be empowered and they need partners, advocates. It’s a very sad comment on our healthcare system, but to be sure that things don’t slip through the cracks, we, the providers, the hematologist, our job is tough, but we need a patient to partner with us.  

So, for example, if you’re a patient with diffuse large B-cell lymphoma as your diagnosis, make sure to ask, “Was there a result for the FISH?” You need to make sure that doesn’t slip through the cracks. Or, if you are going for a second opinion or going to another medical center, make sure you have your records. I really wish that every patient who had a scan of one kind or another as they walked out the door got a copy of that scan, a disc. Now, that would make life so much simpler. But, make sure that you keep your own records. It’s hard and hopefully, every sick individual has a family member or a friend, someone who’s going to help them with this because this is very tough.  

But, ask questions. “Are there clinical trials I might be eligible for? Are there alternatives to the therapy you’re recommending?” These are all important questions to ask. Don’t be afraid to say, “With this treatment, what is the likelihood that my disease is going to come under control and be cured?” I think you need to know that. And, “Is there a difference between this treatment and that treatment?” Do we know? Oftentimes, we don’t have the answer for the newer treatments, but we’re hopeful.  

I just want to underscore the existence of a growing number of clinical trials that patients need to consider and think about. It’s hard at the time of the new diagnosis to be struck with not only the emotional impact of a new diagnosis and so on and not feel well and so on, but just ask the question. “Are there clinical trials I might consider?” So, that’s important, and also have optimism because the vast majority of patients, we do amazing, amazing things, and that’s why it’s so much fun to be a hematologist right now is that we have so many new and exciting treatments. And what’s more exciting than to make someone healthy again?  

So, these are exciting times. 

What Is a JAK2 Mutation?

Editor’s Note: This resource, What is a JAK2 Mutation?, was originally published by MyHealthTeam.


One of the most commonly mutated proteins found in myeloproliferative neoplasms (MPNs) is the protein Janus kinase 2 (JAK2). This important discovery has changed how doctors diagnose and treat people with MPNs. We will be discussing both the JAK protein and the JAK gene.

MPNs are blood cancers caused by the overproduction of blood cells in the bone marrow. Mutations in the gene controlling JAK2 protein production occur most often in the three classic types of MPNs:

The V617F mutation in the JAK2 gene is found in:

  • 96 percent of polycythemia vera cases
  • 50 percent to 60 percent of primary myelofibrosis cases
  • 50 percent to 60 percent of essential thrombocythemia cases

Additionally, more than 50 different JAK2 mutations have been found in other parts of the JAK2 gene, primarily in PV cases.

What Is the JAK2 Gene?

The JAK2 protein plays an important role in controlling the production of blood cells from stem cells found in the bone marrow.

The JAK2 gene is responsible for genetically coding the JAK2 protein. This protein is part of the JAK/STAT pathway, which transmits signals to promote cell growth.

When the JAK2 protein is activated, it relays a signal to the protein STAT, which then binds to another STAT molecule in a process called dimerization. This group of molecules then moves into the cell’s nucleus, turning on genes that tell the cell to grow and proliferate.

What Causes JAK2 Mutations?

There are two main types of JAK2 mutations found in MPNs.

V617F Mutation

The V617F mutation is caused by a change in a single base in the genetic code. This simple change then switches the amino acid valine (V) to phenylalanine (F) at position 617 in the JAK2 protein, changing the shape of the protein. When this mutation is present, JAK2 signaling is turned on and cannot be turned off, leading to uncontrolled cell growth. In the case of MPNs, this causes an overproduction of blood cells, leading to blood cancers.

Multiple Mutations

Many different types of mutations can be found within multiple parts of the JAK2 gene. More than 50 different mutations have been identified in the gene, and almost all of these occur in people with PV.

One part of the JAK2 gene is particularly susceptible to mutations. This area genetically codes for a linker that connects two parts of the JAK2 protein. Common mutations here include deletions and insertions. A deletion is when entire pieces of the protein are lost. Insertions occur when incorrect pieces are put into the protein. Insertions and deletions change the shape of the JAK2 protein, which can affect its function.

Do JAK2 Mutations Cause MPNs?

MPNs are caused by a mutation in a single stem cell found in the bone marrow. These mutations cause the cell to rapidly divide, creating too many of one cell type. JAK2 gene mutations are involved in many cases of MPNs. In addition to JAK2 genesmutations found in CALR and MPL genes are also common contributors to the development of MPNs. These three mutations are usually mutually exclusive, meaning that if one mutation is present, then the others are not.

JAK2 Mutations and MPN Diagnosis and Prognosis

A number of tests are required to diagnose MPNs, each providing a different piece of information. The doctor will begin with a physical examination and health history. They may also order a complete blood count (CBC) with a differential, which assesses the number of red blood cells, platelets, and white blood cells.

Because most MPNs are associated with a specific genetic mutation, a pathologist may use blood samples to test for these. Two tests used to identify genetic abnormalities are quantitative polymerase chain reaction (qPCR) and fluorescent in situ hybridization (FISH). Typically, only one of the two tests is required for diagnosis. It is also an option to perform DNA sequencing to identify the driving mutation in an MPN case.

Quantitative Polymerase Chain Reaction

Quantitative polymerase chain reaction (qPCR) is the most commonly used method for diagnosing JAK2 mutations. qPCR is also the most sensitive test, and it can detect small amounts of mutation when other methods fail.

With qPCR, DNA obtained from a blood test is mixed with a fluorescent dye, which is run through a machine that amplifies the sequences containing the JAK2 mutation.

Fluorescent In Situ Hybridization

This test determines whether someone has chromosomal abnormalities contributing to a cancerous phenotype. For example, one type of MPN, chronic myeloid leukemia (CML), is characterized by the presence of a Philadelphia chromosome (named for where it was discovered). A Philadelphia chromosome forms when two pieces of broken chromosomes stick together. This is also called the BCR-ABL1 gene, because one broken piece contains the BCR gene, and the other contains the ABL1 gene.

Most people with MPNs who are Philadelphia chromosome-negative (Ph-) have the V617F mutation in JAK2. This important discovery revealed the driving mutation behind Ph- MPNs. Before the discovery of JAK2 mutation, the cause of these defects was unknown. This also led to the development of specific JAK2 inhibitors for treatment of myeloproliferative disorders.

In 2016, the World Health Organization (WHO) revised its document “WHO Classification of Tumours of Haematopoietic and Lymphoid Tissues.” This revision included new criteria for diagnosing MPNs by the three main driver mutations in JAK2, CALR, and MPL genes. PV is characterized by the presence of a JAK2 mutation. ET and MF are characterized by the presence of any of the three driver mutations.

JAK2 Mutations and MPN Treatments

Since the discovery of JAK2 mutations in MPNs, researchers have developed a number of inhibitors targeting the protein. There are currently two JAK2 inhibitors approved by the U.S. Food and Drug Administration (FDA) for the treatment of MPNs:

Jakafi

Jakafi (ruxolitinib) is approved for treatment of MF hydroxyurea-resistant PV. It is also being investigated for use in people with hydroxyurea-resistant ET. Additionally, some trials are investigating the effects of Jakafi in combination with the antimetabolite chemotherapies Vidaza (azacitidine) and Dacogen (decitabine). Antimetabolites are a special type of cancer drug that interfere with DNA by acting as a substitute for the normal building blocks of DNA.

Inrebic

Approved in 2019, Inrebic (fedratinib) is the newest MPN drug in almost a decade. It’s used to treat three forms: high-risk MF, post-polycythemia vera MF, and post-essential thrombocythemia MF with splenomegaly (enlarged spleen).

Other JAK2 inhibitors are currently in phase 3 clinical trials, including Pacritinib for the treatment of MF and severe thrombocytopenia, and Momelotinib for the treatment of MF. These promising new drugs are in final phases of testing.

Overall, the discovery of JAK2 mutations in MPNs has helped advance drug research, development, and MPN treatment. It has also helped combat uncontrolled proliferation of blood cells, improving the lives of people with MPNs. New medications continue to be developed and tested, providing a hopeful future for those affected by myeloproliferative diseases.

Three Tests You Should Have Before Seeing a CLL Specialist

What are three tests patients should have before seeing a CLL specialist? In the “What Tests Should I See Before Seeing a CLL Specialist?” program, expert Dr. Nadia Kahn from Fox Chase Cancer Center shares three tests that chronic lymphocytic leukemia (CLL) patients should get to assist with predicting each patient’s CLL progression, treatment response, and waiting period before starting treatment.

1. Fluorescence in Situ Hybridization (FISH) Test

In a fluorescence in situ hybridization (FISH) test, the function of fluorescence is used to identify genetic mutations from CLL and where the mutations have been relocated to. The information gathered from FISH testing helps your doctor determine your CLL prognosis and optimal treatment options for your specific CLL.  

2. Immunoglobulin Heavy-Chain Variable Region (IgVH) Mutational Test

In IgVH testing, immunoglobulin gene mutation status is checked for the expression in CLL cells. The IgVH mutational status then helps the CLL specialist determine which CLL subset the patient’s disease falls under – which helps in determining the disease progression that is likely to occur in that patient.  

3. TP53 Sequencing Test

In a TP53 sequencing test, a mutation in the TP53 gene – translated as tumor protein 53 – is searched for. Normal function of the TP53 gene helps prevent the growth of tumors. But when TP53 is mutated, it may lead to uncontrolled cell growth and then cancer growth. TP53 mutation can either be passed down from your parents or can result from environmental factors that cause a mistake during the cell division process. The result of the TP53 sequencing test will help determine CLL prognosis and treatment options.

By getting the three vital CLL tests of FISH, IgVH mutational, and TP53 sequencing tests, they can help in determining a CLL patient’s prognosis and best treatment options. If you’d like to learn more about CLL, check out our CLL information.

Transcript:

Katherine Banwell:

Once a patient begins therapy, how do you monitor whether a treatment is working?

Dr. Usmani:

So, as part of the diagnostic work-up, we typically have identified in the blood using serum protein electrophoresis and serum free light chains. What kind of myeloma proteins these – that particular patient’s myeloma cells are making. And we can monitor them every cycle of treatment. So, every three or four weeks.

And that’s the most noninvasive way of seeing if the treatment is working. The second obviously important thing is if someone has symptoms. If they have kidney damage, if they have bone pain, all of those things start improving as you’re getting treatment. And then in some patients, we’re also looking at imaging like PET CT scans at certain time points. And at some point, we do also look at the bone marrow biopsies to see what’s really going on in the factory.

Katherine Banwell:

We often hear the term MRD, or minimal residual disease used in the myeloma space. So, what is it exactly and how is it used in patient care?

Dr. Usmani:

So, minimal residual disease is a way to measure how much myeloma is left over in a given patient.

And historically, we were simply looking at the serum proteins and the light chain levels along with just the morphology of the bone marrow to see if – kind of determine a response. But we can have a much deeper assessment of how many cancer cells as a leftover from a bone marrow biopsy by different measurements. Someone can be in a complete response with M-Spike is gone. The light chains have normalized.

Yet they can still have 10,000 – 100,000 myeloma cells still in the bone marrow. And just using the bone marrow biopsy the way that we used to, we won’t be able to see them. We’ll just see, “Oh, these look like normal plasma cells.” So, using next-generation sequencing and flow cytometry, we can look at normal myeloma cells at a very deep level – one out of one million.

But these tests are highly specialized. And especially the flow cytometry requires a lot of expertise. The NGS requires good sampling at the time of diagnosis as well as subsequent specimen

How can the results of these tests affect prognosis and treatment?

Dr. Usmani:

So, currently for the most part, we’re treating myeloma patients in a similar fashion. Except for some tweaking based on these quote unquote high-risk features. So, there are certain chromosomes abnormalities that tell us that a patient has a higher chance of relapsing early even if they get the standard of care treatment. So, we try to enroll those patients into a clinical trial or have better optimization of their induction treatment and their maintenance strategy.

So, identifying these high-risk abnormalities is important because our treatment decisions may be modified for that patient’s disease. Or we might be able to get them to a clinical trial sooner than later.

Katherine Banwell:

Right. What is risk stratification? And how is it used in patient care?

Dr. Usmani:

So, risk stratification helps us identify people who are going to do well in terms of getting to a good response and maintaining that response and maintaining being progression free or being disease free versus those folks who maybe relapsing sooner. And that’s called risk stratification. So, you are essentially identifying and dividing patients into two different buckets saying, “All right. I have to pay attention to this person a bit more because they can relapse soon. So, I’m going to be keeping an eye on their labs and such very much, much closely.”

Katherine Banwell:

Let’s talk about therapy for myeloma patients. How are low-risk patients treated?

Dr. Usmani:

So, typically, the low or standard risk patients are treated with at least a three-drug induction treatment at the time of diagnosis. Or sometimes with four-drugs if you combine an antibody treatment. There are various regimens but the standard of care is at least three drugs. Then for patients who may be eligible for a stem cell transplant, they go on to receive autologous stem cell transplant. Once they’ve recovered from the stem cell transplant, they go on to maintenance treatment.

And the idea is that the induction along with stem cell transplant for those patients who are eligible gets patients to as deep as a response as possible. And the concept of maintenance is you maintain them in that response and delay the disease from coming back.

Katherine Banwell:

Right. And then what about high-risk patients? How are they treated?

Dr. Usmani:

So, for high-risk patients, we typically prefer using a four-drug regimen. Either daratumumab RVD or carfilzomib with Len Dex or KRD as induction treatment for high-risk patients. After the stem cell transplant, most patients would continue both the lenalidomide as maintenance along with the proteasome inhibitor. If patients had low or standard risk disease, they would only be getting lenalidomide as maintenance. So, here for high-risk patients, you’re adding a proteasome inhibitor.

Katherine Banwell:

What tests are necessary to help understand a patient’s specific disease both at diagnosis and prior to treatment?

Dr. Usmani:

So, the testing includes – what’s the objective of testing – we do tests to help diagnosis to assess how much of cancer we’re dealing with and then what kind of cancer we’re dealing with. Even within a given cancer, how much cancer you have and what kind you have is important. Folks can have a little bit of cancer in terms of burden. But it can be aggressive in its nature. So, you can have King Kong at your door, or it could be the green giant just trying to serve up veggies. Whereas King Kong will bite your head off.

So, with that in mind, there are things that we do such as blood tests to see effects on blood counts, kidneys, liver. We also do certain blood tests to identify what kind of multiple myeloma a patient may have as an example. So, the kind of myeloma protein they’re secreting. The kind of light chain they’re secreting. Then urine tests are done to see if there are any proteins that are leaking through the kidneys if there is kidney damage. Then bone marrow biopsy to a) look at how much myeloma and b) what kind by specific testing that we do on the bone marrow biopsy. And then imaging to see what parts of the bone’s affected.

Katherine Banwell:

Great. I’m assuming that these tests will help with the opening of the stages of myeloma.

So, how is myeloma staged?

Dr. Usmani:

So, the staging of myeloma is still a work in progress. The reason why I say that is we have a good way of accessing how much myeloma a patient may have. But if we don’t combine it well with what kind or how aggressive it may be. So, staging in myeloma relies on two blood tests that are serum albumin and serum beta-2 macroglobulin.

And they help us give a good assessment of how much myeloma patients have. And maybe a little bit of information about whether patients may have a bit more aggressive kind. But then you overlay that with cytogenetic information from the myeloma cells that are from the biopsy as well as another blood test called LDH.

If patients have any of the quote unquote high-risk features, they are – along with a high level of beta-2 microglobulin, you stage them as stage 3. If they don’t have them, they’re stage 1. If they have some of the features, they’re kind of in between in stage 2. And that’s how we stage multiple myeloma.

Katherine Banwell:

You mentioned cytogenetics. What testing is involved in that?

Dr. Usmani:

So, bone marrow biopsy – it’s very broad. But there are two parts to it.

One part is getting the bone marrow aspirated where we insert a needle into the pelvic bone and get parts of the bone marrow – the blood inside the bones out. And look at how much percentage of plasma cells are there. What kind of surface markers or features they have.

And then we look at if those cancer cells have any chromosome abnormalities that are unique to myeloma. And some chromosome abnormalities can be high-risk.

What does high-risk mean? High-risk means if you treat patients in a certain fashion, they have a higher chance of relapsing or a higher chance of the myeloma coming back out of remission. So, we identify those features by way of looking at cytogenetics. And there are different techniques in which we can take a look at that.

Katherine Banwell:

And what are those techniques? There’s something called FISH, right?

Dr. Usmani:

Yes.

Katherine Banwell:

And flow cytometry and also next generation sequencing?

Dr. Usmani:

Yes. So, and there is also conventional cytogenetics. So, flow cytometry looks at the different proteins that are part of the surface of any cell – any blood cell for that matter. It could also be any other cell as well, not just blood cells.

But in this particular case when we do flow on the blood marrow aspirate, we’re looking for unique features of those myeloma cells. But that does not tell us anything about the chromosomes. Conventional cytogenetics is the old fashion way. It’s a 40 – 50-year-old technique in which you make the cells in a test tube. You make those cells go through cell division. Each human cell has 46 chromosomes or 23 pairs. And when the cells are dividing, those chromosomes kind of line up in the center.

And the old fashion technique of conventional cytogenetics was take a look at the cells when those cells – when the chromosomes are aligned, and see if some parts of the chromosomes are missing or one chunk of one chromosome has attached to the other. That’s the old fashion way. The FISH technique, what it does is it’s geared toward identifying specific abnormalities.

And one part of that particular protein or molecule that goes and attaches to that chromosome has a color-coded probe. So, you can see within a cell different colors light up. And based on those unique features, you can identify “Okay. This cell over here is missing a part of chromosome 17. Or this part of chromosome 14 is attached to chromosome 4.” That’s FISH. So, FISH is very specific. Conventional cytogenetics is not. Next-generation sequencing, there are – that’s a broad term.

You can measure different types of nucleic acids: RNA versus DNA. And those different techniques identify specific – they can identify specific mutations in a cancer cell.

So, each of these techniques provide different layers of information for our myeloma patients.

Why should you ask your doctor about essential myeloma testing?

When a patient is diagnosed with myeloma, they typically undergo a series of tests that aid in diagnosing and staging their individual disease. The standard tests include:

  • Blood Test
  • Urine Test
  • Bone Marrow Biopsy, and
  • Imaging

As research in the field evolves, genetic profiling via more in-depth cytogenetic testing is increasingly common to further classify your myeloma. This testing often identifies unique biomarkers of the myeloma, such as translocations or changes in chromosomes.

So why do the results of these tests matter?

  • The presence of certain biomarkers can indicate a patient is low-risk, which can suggest a more positive prognosis.
  • There are certain biomarkers that indicate high-risk myeloma, meaning an aggressive treatment approach may be more effective.

Knowing your risk in myeloma is useful to your healthcare team when choosing a treatment approach or may help in determining if a clinical trial might be right for you.

How can you Insist on the best care for YOUR myeloma?

  • First, always speak up and ask questions. Remember, you have a voice in YOUR myeloma care. Your doctor is expecting you to ask questions and should be able to answer them.
  • Ask your doctor if you have had or will receive genetic testing for risk stratification and how the results may impact your care and treatment plan. Be sure to ask for paper or electronic copies of your important test results.
  • And finally, bring a friend or a loved one to your appointments to help you process information and to take notes.
