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.

Transcript:

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 Does Essential Testing Affect Myeloma Care and Treatment? 


Transcript:

Katherine Banwell:

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.

Transcript:

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.

Katherine:

Hello. And welcome. I’m Katherine Banwell, your host for today’s program. Today, we’re going to discuss how to access the most personalized care for your myeloma and why you should insist on essential testing. Before we get into the discussion, please remember that this program is not a substitute for seeking medical advice. Please refer to your healthcare team about what might be best for you. Okay. Let’s met our guest today. Joining me is Dr. Saad Usmani. Dr. Usmani, would you introduce yourself please?

Dr. Usmani:

Certainly. Thank you for inviting me, Katherine. I’m Saad Usmani. I’m the incoming chief of myeloma at the Memorial Sloan Kettering Cancer Center in New York.

Katherine:

Excellent. Thank you for taking the time out of your schedule to join us today. Before we delve into the discussion, let’s start by defining a term that we’re hearing more frequently. What is personalized medicine?

Dr. Usmani:

Personalized medicine is a fancy term to examine different aspects of a patient’s health outside of their cancer diagnosis. And also, the cancer itself – factors that are associated with good response to treatment or an early relapse from treatment. So, it’s a holistic kind of an approach that looks at all of these factors together. Also, looks at the patient’s mental and social well-being and comes up with a game plan for them.

So, I would probably divide the various factors that kind of come into play with the personalized medicine or personalized approach to cancer treatment by taking into account factors that are patient-related, factors that are cancer- or disease-related, and then factors that are related to treatments that they maybe receiving.

So, these three kinds of combined together to form a plan that is unique to that individual patient.

Katherine:

Right. 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 in 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.

Katherine:

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:

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 autologus 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:

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 (Daralex) RVd or carfilzomib (Kyprolis) 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 f 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:

Right. I see. Okay. And where do clinical trials fit into treatment?

Dr. Usmani:

So, as a clinical researcher, I’m a big proponent of telling my patients that if there’s a clinical trial that’s available to you, it doesn’t matter which stage of disease you’re at. Whether you’re newly diagnosed, or another myeloma has come back. Consider a clinical trial as your first and best option. Talk to physicians about both the standard of care options as well as clinical trial options.

Most clinical trials in myeloma are not someone getting treatment and the other person not getting anything. The trials that we’re doing, patients are getting at the very least the standard of care treatment. So, I would say that the – yeah. I mean, the clinical trials end up being the best option for majority of patients instead of standard of care.

Katherine:

Who is stem cell transplant right for?

Dr. Usmani:

So, stem cell transplant are kind of a misnomer. There is nothing magical about getting your own – collecting your stem cells and giving them back to you. I think the stems cells are – the way that – what they’re really doing is helping the patients bone marrow recover from the melphalan chemotherapy that’s given as part of the stem cell transplant because it’s melphalan, which was our first anti-myeloma medicine discovered back in the ‘50s and early ‘60s. That has been a mainstay of treatment of myeloma for six, seven decades now.

But if you give high doses of melphalan, there’s certain side effects. It can damage the stem cells and delay blood count recovery. So, that’s why patients get stem cells. So, in the body of evidence we have, most myeloma patients would be eligible for a stem cell transplant either at the time of diagnosis or if they decide to collect their stem cells and hold it back for the first relapse. That would be the other setting. But age is not a barrier. It’s more about how fit a patient is. And this is where a comprehensive myeloma geriatric assessment becomes important because an eyeball test is not good enough. You need to have more complex assessment of patients. So –

Katherine:

So, this is looking at comorbidities.

Dr. Usmani:

It is looking at comorbidities.

It’s looking at performance status. It’s looking at cardiopulmonary reserve. It’s looking at cognition and mental health as well. So, all of those factors. And obviously besides that, if you don’t have good social support, then going through a stem cell transplant becomes a challenge as well. So, there’s all these factors that kind of come into play together.

Katherine:

Yeah. Dr. Usmani, how is immunotherapy advancing in this field?

Dr. Usmani:

I think that’s the big area of research and clinical therapeutics over the past five or six years is immunotherapies. And it’s a broad umbrella. There are a few things that kind of fall under it – under that category.

So, it includes antibody-based treatments, includes CAR T-cell therapies. Yeah. I mean, it’s a very active area. Again, we can have a one-day seminar just talking about all the advances that are happening in that specific space. But that’s the new frontier. I think that’s the immunotherapies play a big role in finding a cure for myeloma.

Katherine:

You mentioned CAR T-cell therapy. Is it showing a lot of promise in myeloma care and treatment?

Dr. Usmani:

It is in the relapse refractory as in the advance refractory patients as well as in early relapse patients. And we are just starting to do clinical trials in newly diagnosed, high-risk patients. So, yes. It’s showing good promise. One advantage of CAR T-cell therapy is once you get the CAR T-cell therapy, it’s a one and done deal.

You just get CAR T-cell therapy and there’s no maintenance. So, patients really enjoyed that part of being off of therapy. They go into remission and then they don’t have to take anything for months or even a few years. So, I think that’s the biggest excitement about CAR Ts.

Katherine:

Yeah. 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:

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.

Katherine:

Here’s a question we received from a viewer before the program. Mary writes: “I was just diagnosed with MGUS, and I’m obviously very concerned. What should I be looking for and how often should I check in with my doctor?”

Dr. Usmani: That is a very good question. MGUS is a precursor disease to myeloma and other class cell muscle disorders. And based on the original homestead county data from the mayo clinic, if there were 100 folks who had MGUS, one out of 100 every year would – there’d be one percent likelihood of them progressing to myeloma or some other plasma cell disorder.

So, the overall risk say in the next 20 years for a given patient is fairly low. And what we look at when we’re determining how frequently to check the blood or see the patient is the value of that M-spike.

If it’s a high value, if it’s two or three, we’ll be checking the labs more frequently every three months or so. Maybe seeing them every six months for the first year or two. If the M-spike value is very low, it’s one gram or less, we might be just checking labs once or twice a year and seeing patients once a year. But I would highly recommend in addition to seeing your regular hematologist who diagnosed you with this MGUS to do seek an opinion at a myeloma center of excellence.

Katherine:

Okay. If a patient is interested in participating in a clinical trial, what question should they ask their doctor?

Dr. Usmani:

The question that they should ask each time when you’re at that fork is can you please share with me what clinical trial options I have and compare them. Give me more information about “How do they compare with the standard of care treatments that are being offered?” And if you do not have any clinical trial options, would it be worthwhile, to again seek an opinion at a myeloma center of excellence to see if there are clinical trials available.

And in today’s day and age, you can have a virtual consult with a myeloma center of excellence. You don’t have to even go in. You can just chat with an expert on video and see if a clinical trial maybe right for you.

Katherine:

Are there common misconceptions you hear from patients concerning clinical trials?

Dr. Usmani:

Yeah. I think the most common perception patients have is “Oh, I’m going to be used a Guinea pig for something that hasn’t been used in humans before.”

Katherine:

In a human before. Exactly.

Dr. Usmani:

So, most of the clinical trials are not first in human trials. Yes. We do have first in human trials where we are using novel treatments in some instances.

But there is strong rational and safety guardrails built around that. And if you’re participating in a first in human study, it’s highly likely that the other treatments have stopped working and there might not be other options. However, majority of trials that patients end up participating in are getting at least the standard of care treatment. So, I think it’s very clear to kind of communicate this to patients that, “Hey, you are going to be getting a standard of care treatment even if you go on the quote unquote control arm. It’s not that you’re getting placebo.”

So, I think clarifying what the protocol is, giving patients information kind of alleviates some of those concerns. But that’s the most common misconception people have.

Katherine:

If patients are concerned about voicing their concerns and I think many of us are, why should they feel like they’re a partner in their care?

Dr. Usmani:

Well, that’s the only way that they will feel empowered. And we have to remember why we’re doing this, right? So, we’re doing this so that we can alleviate the burden of this disease from our patients and give them as good of quality of life as possible. And it’s a partnership. And in that partnership, the patient is the most important partner. Everyone else – it’s like you’re the main character.

The patient’s the main character in the movie. And all of us are supporting cast around them. I think that’s how you have to approach it. That’s how – that’s why it’s very important. And of course, patients – we’re not expecting our patients to read the papers and be knowledgeable about everything. But have a general sense of what to expect and it will be – so, having a more educated patient helps them deal with treatments better and have realistic expectations of what’s to come.

Katherine:

Right. As I mentioned at the start of this program, Dr. Usmani, patients should insist on essential myeloma testing prior to choosing a treatment. As we conclude, I think it’s important to point out that some patients may not know if that can even receive these important tests. So, what key question should they ask their physician about them?

Dr. Usmani:

So, you should be asking your physician about what kind of myeloma you have? What stage of myeloma you have? How much involvement in the bones you have? Do you have any chromosome abnormalities or any features of disease that put you at a higher chance of the myeloma coming back?

As you ask these questions, your physician will be prompted to think about “Okay. Am I missing something in my work?” And you can always ask is there anything else you need to do in terms of testing to give you a better idea of how best to approach my treatment and follow up.

Katherine:

I’d like to close by asking about developments in myeloma research and treatment.

What’s new that you feel patients should know about?

Dr. Usmani:

Oh, my. We can spend a long time with this answer. I would say that we understand what’s driving myeloma as a disease. We have a better understanding of what’s going on with the rest of the immune system and the bone marrow microenvironment where the myeloma cells live. So, the treatments that are being developed right now are trying to combine different ways in which you can shut the myeloma cell down by targeting those abnormalities or those abnormal pathways. And also, to harness the patient’s immune system to go after the cancer cells. So, combining what we’re calling immunotherapy with small molecule or more cancer directed treatments.

So, I think that’s kind of where the field is headed. And it’s – these are smarter strategies, smarter treatments. And we’re moving away from old fashioned conventional chemotherapies.

Katherine Banwell:

If a patient wants testing beyond the standard, what should they be asking their doctors for?

Dr. Shah:

Well, thankfully a lot of these tests can be done as a standard. We actually have some approved testing for it. So, the most important thing is to ask the doctor at all. For example, the patient may ask, 1.) “When will my next bone marrow biopsy be?” and 2.) “When I get that bone marrow biopsy, will you be looking at cytogenetics and FISH?” and 3.) “When you get the bone marrow biopsy, will you be also looking for minimal residual disease?” And finally, “What technique will you use to look for that minimal residual disease?” There are different ones that the patients might find useful to know about.

Katherine Banwell:

What are some of the different techniques?

Dr. Shah:

There are a variety of ways that we can look for minimal residual disease. One of them is called flow cytometry. What that is is you send all the cells that are in the bone marrow through a chute, and in that chute you can sort of detect one or however many cells that are – that have a specific characteristic on their cell surface.

You think of it as a bunch of balls with lollipops sticking out of it. And based on the characteristics of those lollipops, you can tell if there are any plasma cells or myeloma cells. Another thing we do with minimal residual disease, another technique, is called the next-gen sequencing or NGS.

And for that, we need to know the specific DNA sequence that is very personal to your myeloma cells. So, your particular plasma cell or the cancer cell will have a sort of sequence, a specific sequence that can be identified when you’re first diagnosed. And if you have access to that tissue, that can be sent off to the company, and they use that as sort of a template or a measure – an individual identification. And then, they scan the subsequent bone marrow samples against that to see if there’s any sequence that matches that original one, and that’s the way you can detect one in a million positive cells, if there are any.

Katherine Banwell:

What is minimal residual disease testing, and when should it take place?

Dr. Shah:

Minimal residual disease is exactly what it sounds like. It’s the disease that you can’t see under the microscope, but it’s still there.

And I sort of equate it to the little deep food particles that are in a pot after you clean it and really, really scrub it, but still, something is in there. And that’s what it is for myeloma. And really, that depends on how sensitive your test is. We now know we can test for at least one in a million cells by some advanced techniques, and we like to test to see if there’s any disease left after certain treatments are done – for example, after a patient undergoes an autologous stem cell transplant.

Katherine Banwell:

What impact do results have on care decisions?

Dr. Shah:

Minimal residual disease testing can be useful for patients to understand the true burden of their disease. For example, it may be that there’s no more M-protein in the blood, or the light chains are normal, or even the bone marrow showed no plasma cells. But the minimal residual disease testing may show that, in fact, there are a few cells still in there, and that can help patients to decide, “Yes, I want proceed with maintenance therapy,” for example, or “No, I would not like to.” Although, we generally recommend it, patients like to have as much information as possible to make their decisions.
