Katherine:

Dr. Rosko, what do the results of these tests tell you about prognosis? 

Dr. Rosko:

Yeah, I think this is a really important question. And, in my experience, when we encounter a patient newly diagnosed with myeloma, it is like drinking from a firehose in terms of the amount of information that we are reviewing and the amount of information that we are discussing with the patient and with their family. And oftentimes, we talk about this piece of these cytogenetic abnormalities, and we talk about – but I really encourage your patients and anyone who is listening in today to really take a deeper dive. 

Because sometimes it’s helpful as, one, you’re navigating a new cancer diagnosis, but that’s challenging in and of itself. And then, two, talking about a cancer, multiple myeloma, that is – most people don’t know so much about multiple myeloma, unlike breast or colon or lung cancer, and so I really encourage patients and their caregivers. And a lot of times this happens, where we’ll go over all the cytogenetic abnormalities, we’ll talk about how it plays a role in their overall treatment trajectory, and their prognosis, but also good just to circle back and say. 

Settling into what this diagnosis is, oftentimes, people on first time treatment. And then even sometimes months or even years into their diagnosis, they stop and they come back and they say, “Can we talk about this FISH data?  

Can we talk about what changes that I had within the DNA? What does this mean?” And that’s not uncommon at all.  

So, I really feel like for many people that are on the call here today, I think it’s important to say it’s okay to go back to your physician and say, “I’m learning more about this, now that I’m more familiar with what this diagnosis is, can we talk about these FISH changes, or can we talk about the stage of my cancer?” Because I think it’s oftentimes an overwhelming period of time to have a new cancer diagnosis. And I also want to just give permission to everyone on the call that it’s okay to go back and ask questions, even if it’s been months or years.  

So, having high-risk mutation can upstage a cancer and in the absence of high-risk mutations can downstage a cancer. So, what that really means is saying, “These biologic changes that are happening in the cancer cells give a sense of what we anticipate that the trajectory is going to be when someone is diagnosed.” 

Now, it’s imperfect. I feel like cancer just generally is unpredictable, and there are many things that we try as clinicians. And especially with the experience that we have, to say, “This is what we anticipate the course will be like you, in terms of response, in terms of the cancer being quiet.” As you all know, multiple myeloma is not a curable cancer right now. And for all patients, when they’re diagnosed, they’re often able to get disease control and be able for that cancer to be put in remission. And we do focus on remission. 

I think that’s also something that I talk to my patients about. Even though we can’t cure it, we can certainly control it, and that’s a big part of what we do. So, when we get good disease control, we’ll talk more about next therapies, but that is how Dr. Cottini – Dr. Cottini is a wonderful scientific investigator and knows all of the latest and greatest when it comes to different mutations that are identified within cancer cells. We partner very closely with her in terms of  scientific investigation and how the mutations that were newly identified, too, play a role in terms of response to treatment, and how we’re able to best treat them. 

Katherine:

Thank you for that. Dr. Cottini, do you have anything to add as far as what type of questions patients should ask their healthcare team about test results?  

Dr. Cottini:

I mean, I think Dr. Rosko already pointed out the most important things. So, multiple myeloma is a rare disease, and it’s not as intuitive to understand as breast cancer, lung cancer, prostate cancer. 

So, it’s really important as a patient to understand which tests are we ordering. Why are we ordering? How do we monitor the disease? Because that’s one of the most important questions the patient asks, because for different types of solid tumor, we get imaging, and we know that the tumor is growing or not. Where, for us, we look at the markers I had described previously. And sometimes, we maybe see small changes in the markers that are very concerning and worrisome for the patient, but sometimes they are not. So, I think asking questions about the testing and how we treat them and monitor the disease is a very important part of being a good applique for itself.

Katherine:

Part of accessing more personalized care starts with test results. Dr. Cottini, what testing should take place following a myeloma diagnosis?  

Dr. Cottini:

So, once somebody is diagnosed with multiple myeloma, there are different types of tests that we need to get. Some are blood tests, some are urine tests, some are bone marrow tests, and others are just different types of imaging. So, the reason for all these tests is because multiple myeloma can kind of go everywhere and can cause the damage to different types of organs. 

So, if we look at blood tests, usually you would see that you get the complete blood count, so we can count the number of red blood cells, white blood cells, and platelets. And then we’ll look at kidney function, through a chemistry profile, calcium levels, multiple myeloma can affect bone cells can affect kidneys. And then, you will see some more sophisticated tests that are really important for the diagnosis of multiple myeloma but also for monitoring and seeing if you’re actually responding to the treatment or you are progressing. 

These two tests that you can see are kind of difficult to say, but very important and needs to be remembered. So, one is called serum protein electrophoresis with immunofixation. And the other one is free light chain assays. 

And the practicum with these two tests is we can identify the specific marker of the multiple myeloma cells and it is either something monoclonal protein or M-protein or kappa light chain numbers. And as I said before, these numbers can be monitored. So, in response to the treatment, they should go down. And then, unfortunately, if we see progression, they might go up again.

And then, urine tests can also give the same type of numbers. Usually, we have our patient keep the urine for 24 hours, for a day, and we can see if there’s monoclonal proteins or light chains there, too. Then there is a least favorite test of all of them that is the bone marrow testing. So, this is very important for us, because it’s where most of the myeloma cells stay. So, we need to have a look at the bone marrow. 

We need like a piece of the bone and some of the liquid tissue to look at specific characteristics of the myeloma. And then, I said before, the myeloma can go to bones, so we need to kind of get some imaging of the bones. These are usually a set of X-rays – it’s called skeletal survey – to see if there is any area that is abnormal or at risk of fractures.  

Then, we are also looking at PET scan, which is a more sophisticated test that is based on sugar consumption. We know that myeloma cells and all cancers enjoy sugar, so with the PET scan, we can see visually where the myeloma cells are in the body.  

Katherine:

What is cytogenetics? 

Dr. Cottini:

So, this is a really interesting question. So, cytogenetics, or FISH tests, are tests that practical tests  allow us to look at the chromosomes of the multiple myeloma. 

So, everybody has 46 chromosomes, right? Multiple myeloma cells can have more of them or less of them. So, they can have – some myeloma cells have 17 chromosomes instead of 46. So, cytogenetics in the karyotype counts how many chromosomes there are. And then, there is another type of test that is called FISH test, or fluorescence in situ hybridization – I get all the difficult names – that practically look at specific area of chromosome. It can tell us if some areas of chromosomes are lost. That’s what you can read as deletions, or practically missing pieces of chromosomes. 

Or there are extra pieces of chromosomes. These are the amplification gains. Or if there are different pieces of chromosomes that stick together. And these are the translocational chromosomes. And all of these data are important for deciding for knowing how aggressive or difficult to treat the myeloma.  

Katherine:

Dr. Cottini, what mutations or abnormalities are you looking for? 

Dr. Cottini:

So, as Dr. Rosko said, and as I quickly previously mentioned, so there are different types of DNA tests that we can do. One is this FISH test, and that’s a standard test. It’s usually done practically everywhere. And it practically tells us if there are specific deletions or changes. 

And we don’t really have yet a specific medication that we know works for specific abnormalities. But all this information is important to decide, as Dr. Rosko said, number of drugs, and maybe that can be helpful in the future when hopefully thanks to the research, we will be able to say, “Based on this abnormality, you would benefit more from this type of treatment.”   

There are other types of tests. One is called DNA testing, so we look at the mutation. So, really to point to small changes of a particular gene. This is done not routinely, but I think it can still give lots of good information. And there are lots of genes that are normally myeloma, that has potential drugs that have been studied, those with multiple myeloma and any other type of cancer.

Transcript:

Katherine Banwell:

Dr. Blue, how often should bone marrow biopsy be performed in the years following a stem cell transplant?  

Dr. Brandon Blue:

So, typically following stem cell transplant patients are kind of switched to what we call maintenance therapy.  

Meaning that the disease is typically under control after transplant, and our job right now is to kind of put the lid on the disease and keep that lid on so that the disease doesn’t kind of bubble over. And likely, people are on that maintenance therapy for three, four, sometimes even five years, or more. And so, sometimes when the disease is very stagnant or very stable, and people are on maintenance therapy, there may not be a need for multiple repeated bone marrow biopsies. 

Because the disease may just be in a kind of dormant or remission stage. However, at the first sign that we see that things are changing, we see that unfortunately the disease may be starting to relapse, or maybe even there’s a new pain, or things happening that just need further investigation, I think a bone marrow biopsy would be very warranted at that time.  

Katherine Banwell:

Okay. So, when patients are in a kind of remission stage you just monitor them. Do you continue to do bloodwork, and test their urine, and so on?  

Dr. Brandon Blue:

Blood, urine, imaging. Blood, urine imaging. 

Katherine Banwell:

Yeah. Blood, urine, imaging.   

Dr. Brandon Blue:

Yup. Those would be the best ways to follow it. Of course, the gold standard would be a bone marrow biopsy, but typically what happens is that the blood, the urine, and the imaging typically reflect what’s happening in the bone marrow. It’d be sometimes very unlikely for a patient’s bloodwork to be normal, but then the bone marrow to be ridden with cancer. Typically, it doesn’t work that way. There are some unique circumstances where bone marrow biopsies are needed in people who have something called non-secretory myeloma, but that’s a very small percentage.

Transcript:

Katherine Banwell:

What testing and treatments are appropriate for smoldering myeloma? And first, could you define smoldering myeloma for us?  

Dr. Brandon Blue:

Yeah. So, one of the things that makes multiple myeloma kind of a very difficult disease is that it can attack people’s bones.  

When people have the smoldering myeloma, they have none of those bone disease. When people typically have multiple myeloma it can affect their kidneys, and actually cause low blood counts called anemia.  

When people have smoldering, they don’t have any of those classic features, however, they still may have a burden of cancer cells. Anywhere from 10 to 59 percent of plasma cells is really still considered this smoldering, or inactive cancer, but it’s still cancer. And so, we know that roughly in the first five years about 10 percent of those patients will go from this inactive smoldering stage to the active myeloma and required treatment. 

A lot of times we do observation for those patients to kind of make sure that they get the treatment when they need it. There is some studies to show that some people do get treatment during the smoldering stage, but for a lot of times observation is needing because sometimes it can be several years really before someone would need treatment. 

And a lot of times we try not to expose people to treatment if it’s really not necessary at the time.  

Katherine Banwell:

I see. So, it’s more of a watch and wait. 

Dr. Brandon Blue:

Exactly right. And sometimes you actually watch and wait, and then you keep watching, and waiting, and sometimes people never develop the active disease. And so, especially in those patients, you would’ve exposed them to chemotherapy that they really never needed. And one thing that I always tell my patients is that it’s important to know that you have cancer cells, but it’s also important for us to follow it. We are here to help and support you, right? And having cancer in your body sometimes can be very anxiety-provoking. 

And so, for a lot of patients who are in that category, sometimes we offer them clinical trials that we have available to say, “Hey, this is something that we’re trying to explore and learn more about smoldering myeloma. And maybe this is something that may benefit you.” 

Katherine Banwell:

Yeah. Can a patient with smoldering myeloma be monitored through blood work? Is that something you would do?  

Dr. Brandon Blue:

Yeah. So, typically what we try to do because the disease is so multifaceted, meaning that myeloma is not the same for each person. So, the blood is a fantastic way of following the disease, and monitoring, however, we need to do a little bit more than that. We also like to collect urine because, again, multiple myeloma can affect people’s kidneys. And the good thing about urine is that we flush it down the toilet all the time, but there’s so much information that gets flushed down that we really can learn about the disease and learn about the person by following the urine over time. 

The next thing is that we can follow imaging because, again, multiple myeloma can affect people’s bones. Sometimes if you get aches, and pains, we don’t know if that’s the muscle, we don’t know if that’s a ligament, we don’t know if that’s the bone. Pain is such a subjective thing, so we need to follow people, and have them be monitored with imaging. So, I think that combination of blood, urine, and imaging would be the best thing to do.

Katherine Banwell:

Is there any research on predicting hereditary risk of myeloma? 

Dr. Irene Ghobrial:

Yes, so part of the PROMISE study is trying to understand what is the risk of developing myeloma? So, we’re recruiting people who are either African American, because they have a three times higher chance of developing myeloma compared to the white population, as well as people who have a first degree family member with a plasma cell disorder. 

Or even any blood cancer because now we see that CLL and lymphoma and myeloma can actually come together. And we’re now doing something called whole genome sequencing of all of the DNA that you inherit from Mom or Dad called the germ line. Basically, we try to see did you inherit the gene from Mom or Dad that increases your risk to myeloma? 

Now, it’s not as high as something like BRCA1 mutation or 2 mutation, where if you have that, you’re high, high chance of developing breast cancer or ovarian cancer and so on. We probably have several factors that need to be put together. You inherit something and then the environment adds something, and then as we get older, we get the hit. 

Or you inherit something that changes your immune system, and that allows the plasma cells to start proliferating faster because they are reacting as an immune cell, and that allows the hit of myeloma to happen. And we’re working on that, and we would really encourage everyone who has a relative with myeloma, sign up on PROMISE study. 

Because that’s how we can get the answer. That’s how we can say it’s not because you are an African American or you’re white. It’s not because you have a first-degree family member or not. It’s because of this gene. So, taking away race, taking away all of those factors, taking away age and trying to go back to the biology. Is it a certain gene, is it the certain immune cell that makes us go to that risk? 

And then Dr. O’Donnell is really taking it to the next level. Now what is in the macro environment? So, we talked about what we inherit, but it’s like nurture and nature, right? So, nature is the genetics and then nurture, what do we eat? What do we change? Obesity, health, all of those things change our inflammation level and change our ability to basically prevent those myeloma cells from starting or from continuing to progress. And she can potentially talk about her work on microbiome, on the tiny bacteria that are in our body from what we eat. So, maybe, Betsy? 

Katherine Banwell:

Okay.  

Dr. Betsy O’Donnell:

Absolutely. Yes, so one of the things that particularly interests me is the effect of lifestyle on our risk of getting cancer. 

And specifically within plasma cell disorders, and I think there have been other cancers, breast cancer and colon cancer, where they’re a couple steps ahead of us just in understanding the influence of things like obesity and the gut microbiome. So, the specific bacteria that are within your intestinal tract. It makes a lot of sense in colon cancer, but we think that that’s not limited to diseases like that. We actually think that these microbiomes, which are influenced by the foods that you eat, may have a relationship with your immune system. And remember, myeloma is a cancer of the immune system. 

So, we’re all working together on our team here on a very scientific level to understand lifestyle influences and how they may cause or potentiate multiple myeloma. And so we’re excited to kind of bring this piece together. When you think about the spectrum of plasma cell disorders, not everybody goes on to myeloma, but a lot of people sit in these early precursor diseases, MGUS and early smoldering.  

And so are there things that people can do for themselves that might influence their gut microbiome, or if it’s the amount of body fat that we have that’s very involved in cell signaling? Can we modify those things, exercise more potentially, that will decrease our body inflammation levels or alter those pathways that have been set in process that, by altering them, may decrease the risk of going on to more advanced plasma cell disorders? 

Katherine Banwell:

That’s such great information.

Understanding MRD and What It Means for Myeloma Patients


Transcript:

Katherine Banwell:

Dr. O’Donnell, Alex wrote in with this question. “What is the difference between a complete response, VGPR, and PR as it applies to prognosis and maintenance after an autologous stem cell transplant?” And before you answer the question, would you define VGPR and PR for us?   

Dr. Betsy O’Donnell:

Sure. So, we have different criteria that help us understand how well a drug is working, and they’re uniformly used across clinical trials so that we’re all speaking the same language. And so we talk about a PR, a VGPR, and a CR. So, a CR is a complete response, which is 100 percent of that monoclonal protein that we initially detected is gone. We can’t measure it. Or if you have an elevated light chain, which is another piece of the protein, that has gone back down to normal. 

Taking that a step further, astringent CR is if we do a bone marrow biopsy and we can’t find any cancer plasma cells in there. A VGPR is where we see a 90 percent reduction in the amount of protein we can measure, and a PR is anything over – a partial response is anything over 50 percent. 

So, that’s a language we speak really just so that when we’re interpreting clinical trials, we all are using the same criteria. 

And so these are different terms that classify it. If the example that you gave, someone’s had a transplant, what would typically happen 100 days after that transplant is a patient would restart maintenance therapy.   

The classic maintenance is just lenalidomide (Revlimid), which is the pill that they were probably taking before that. And there’s a lot of controversy now but no good answers about changing therapy after a transplant, if you haven’t received a deep response. 

What we do know is that after a transplant, when someone goes on lenalidomide maintenance, they continue to respond. So, the greatest depth of response is not necessarily achieved in the induction phase or right immediately after transplant, but over time on maintenance. 

There’s another tool that we’re now using and incorporating, both in terms of how we assess treatment but also potentially in how we modify treatment, which is something called minimal residual disease, MRD, which goes a step beyond. When people have astringent CR, a CR, looking for really just traces of the disease on a molecular level.  

And all of those help us understand how well the patient has responded and how long that remission might last, but they’re not definitive in terms of how we should adjust treatment based on those right now.

Katherine Banwell:

Dr. Nadeem, many patients are on maintenance therapy following active treatment. So, how is a patient on maintenance therapy monitored? 

Dr. Omar Nadeem:

Yes, so, majority of the time just with blood work. We don’t necessarily need to do a lot of bone marrow biopsies and PET scans for a majority of patients that are on maintenance therapy unless we’re either worried about their blood markers or some symptoms. Generally speaking, any time – it depends on what maintenance therapy they’re on, of course. If they’re just on lenalidomide (Revlimid), which is the most commonly used maintenance therapy, a lot of times we check in with them every one to three months. 

Depending on how their disease status is and how they’ve been doing and whether there’s any side effects that we need to worry about. So, they still have to see their doctors, still have to get the blood work. Usually you can get away with having it done no more than once a month or so, unless they are on other medications along with Revlimid, where we then have to check in with them a little bit more frequently. 

And some of that changes, so patients can be on maintenance therapy for five plus years, and we get a very good sense of how they are doing and kind of how their disease is doing, and we can kind of be a moving target in terms of the frequency of the follow-ups.

Transcript:

Katherine Banwell:

Dr. Ghobrial, how are people with MGUS monitored? 

Dr. Irene Ghobrial:

Yes, so how do we even diagnose them, right? It’s a big question because it’s incidentally found. Someone will go to their primary care doctor and have a little bit of a high protein or slight anemia, and it may not be related, and then their doctor will check for serum protein electrophoresis, and that’s pure luck. We want to take away luck from this equation. We want to take away chance from this equation. 

And we want to start screening people who are at risk, and we are doing that with the PROMISE study. It’s online available to everyone nationwide, international now, where you can sign up on promisestudy.org and try to ask the question that we do for you research level, the serum protein electrophoresis, and a new test called mass spectrometry that is much more sensitive than SPEP to find it. 

Now, once we find MGUS, we want to know what is my own personal risk of progressing to myeloma? Because I could be 30 years old with MGUS, and likely I will progress to myeloma in the next 10 years, 20 years, and by the time I’m age 60, I would have been diagnosed with myeloma. Just a true case in many, many people. If people are diagnosed today with myeloma, they are going to their doctor because they had back pain or anemia, and they are diagnosed with myeloma. In almost all of the cases, they would have had MGUS and smoldering, but they didn’t know about it three years ago, four years ago because they never got tested for it. 

So, we want to change that completely and become proactive rather than being reactive and waiting for symptoms to happen. Once you have MGUS or smoldering, because we don’t know, we start looking for all of the things to help us identify your risk of progression. So, we look at the height of your M-spike. Is it small or big? And then we in many cases say okay, maybe you need a bone marrow biopsy if your M-spike is a little bit on the higher side because we don’t want to miss smoldering myeloma, which will change the prognosis. 

And then we start looking at do you have anemia? Do you have kidney failure? Do you have any of the other things that may predict that you may be actually going into myeloma? 

We also look at it more as a movie rather than as a snapshot, rather than a picture. If your M-spike is changing or your light chain is changing every three months, every six months, that’s an indicator that the cancer cells are doing something. They’re working in there and growing, and that’s why they’re increasing the M-spike and the light chain. 

And that evolving number is actually a very big predictor of telling us that there is a risk of progressing. Those are all clinical markers that we can do. When we look at the FISH, which we talked about, we can tell the certain markers are chromosomal changes that tell you that those cancer cells want to grow a little bit faster. So, 1q abnormality, 4;14, 14;16, 17p, all of those have been shown that when you have them, the cancer cells are not just sitting around and doing nothing. They’re actually starting to grow, and we want to catch them and understand what is the biology of the disease rather than just how many cancer cells you have. 

We do a lot of research level, and potentially now we’re going to give them back to the patients as clinical level, where we can give you more information about that prediction of your risk of progression. One of my colleagues calls it predicting the hurricane. We know that the hurricane will happen, and it’s a question of how precise could you be? We’re the Weather Channel men here.  

And we could be very precise and tell you it’s going to hit Miami at 2:00 in the afternoon tomorrow, and you could be prepared for it and get out of there. Or, you could be completely unprepared because we were not very accurate in our prediction and tell you it may hit the whole East Coast in the next two weeks. That’s not accuracy. So, we want to be more accurate in our prediction of myeloma because one person will never develop myeloma and can go have fun and enjoy life and not be worried and anxious about their risk, and another person we might say let’s watch you more carefully, or let’s think of interception preventing things. 

So, we do things called next-generation sequencing, taking all of those small numbers of cancer cells, even as little as single cells, and we can do whole genome sequencing and give back that information.  

We look at the immune cells and give back that information. We can do mass spectrometry. And with Betsy and Omar, we’re doing more and more tests so that when we have this prediction model, circulating tumor cells and so on, we can be more accurate in giving you that prediction. 

And help you make the next decision of are we watching carefully, are we preventing and intervening with behavior modification with other things? Are we intervening with therapy to intercept the disease? 

Katherine Banwell:

When are more in-depth tests necessary?  

Dr. Irene Ghobrial:

It depends, of course, on everything. I would probably say for every patient, it is a unique discussion. Some patients will tell me, “Let’s watch again in three to six months, and then I will do more testing,” and some patients want to know everything immediately. And we have those discussions with every patient, and we tailor our therapy as well as our diagnostics workup with every patient, depending on how much they want to know, how much their risk is, and how much they want to be involved in that discussion of how much to prevent myeloma.

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.

Katherine Banwell:

Dr. Ghobrial, what is MGUS? 

Dr. Irene Ghobrial:

So MGUS, or monoclonal gammopathy of undetermined significance, is a precursor or the stage before myeloma happens, and it’s actually a very common disease or entity in many, many of us as we get older. In fact, maybe 5 percent of the population over the age of 50 would have this early MGUS. 

It doesn’t mean that it’s cancer. It’s a precursor to cancer, and we can talk more about it as we go on. 

Katherine Banwell:

All right. Is it the same as smoldering myeloma, or is that something different? 

Dr. Irene Ghobrial:

It’s not. It’s an earlier stage than smoldering myeloma, and it’s hard to actually make the right definitions. But currently what we say is if you have more than 10 percent cancer cells or plasma cells in your bone marrow, then it’s smoldering myeloma. And by the name, smoldering, it’s almost myeloma. It’s ready to go on fire, but it’s not there yet.  

MGUS is before that, and the difference is that the chance of progression from MGUS to myeloma is only 1 percent per year, so many, many people will never progress to myeloma. While smoldering myeloma, just because there are more cancer cells in the bone marrow, has a higher chance of progressing, which is 10 percent per year. And in some people, a very high chance of progression of 50 percent in two years. 

And we want to make sure that we catch those cases early and not wait for myeloma to happen. 

Katherine Banwell:

How would you define myeloma? 

Dr. Irene Ghobrial:

So, myeloma is currently defined as the same thing. The number of plasma cells in the bone marrow could be above 10 percent or more, or you have a protein in the blood. But the problem is that you’ve already had problems. You’ve had symptoms of end organ damage, so we have either high calcium, bone lesions, or bone fractures, anemia, kidney failure.  

And then now or more recently, we added a few more things to tell us these people are going to really develop myeloma soon. So, it used to be part of smoldering myeloma, now it’s part of the definition of myeloma, so that we can treat patients earlier, which is if your light chain level is very high, above 100 for a ratio, or if you have multiple lesions by something called an MRI or a PET CT scan instead of the traditional X-rays, or if your bone marrow has a lot of the plasma cells, more than 60 percent. 

And these were new definitions to make sure we don’t wait too much until people have an organ damage or symptoms and then we treat them. And you’ll hear from us that we think we should be treating people even earlier than that.

Katherine:

Have there been advances in molecular testing for myeloma patients?  

Dr. Khan:

Molecular testing is a broad term and can indicate checking genes, proteins, and other molecules. Even let’s say speaking outside of the world of myeloma, molecular testing can be used to determine in individuals if they have a high chance of developing cancers or other diseases.  

It can be done to confirm so cancer diagnoses using the tissue biopsy specimens. It can also be used to help plan treatment, find out how well the treatment is working, provide prognosis information, and other information. In the world of myeloma, there are – in the world of myeloma, there are researchers looking at all of these molecular changes that can happen with disease.  

Katherine:

So, how do the results of these tests affect treatment?  

Dr. Khan:

There’s a particular cytogenetic change called translocation 11;14 that’s found in maybe a quarter of all patients with newly diagnosed myeloma, and it predicts a high likelihood of responding to a new drug called venetoclax.  

In the clinical trial of venetoclax, when it was given to all patients with multiple myeloma, there was actually higher mortality in patients when given venetoclax in combination with bortezomib and dexamethasone. And this is despite a higher response rate by adding the venetoclax.  

The thought process was maybe those patients were not doing well because of higher chances of serious infections. But when they took the data and they looked at that subgroup of patients with the translocation 11;14, there was no such concern in that subgroup. So, in this case of having translocation 11;14, it actually giving you a new treatment option based on the findings of the molecular testing. 

We participate in a national clinical trial called MyDRUG, and that’s looking at other molecular changes to see if a more targeted treatment when added to the backbone of myeloma therapies translates to better outcomes.  

Another recent development in molecular testing is diagnostic testing for minimal residual disease, and that’s from the bone marrow in patients with multiple myeloma.  

The most commonly used test in clinical trials is the clonoSEQ test; it’s an FDA-cleared diagnostic test. The way it works it looks for specific DNA sequences on the receptors of the cancer cells. So, each cancer cell has like a genetic barcode.  

Using the liquid part of the marrow, we can look for those cells that harbor that genetic barcode. 

And the test is so sensitive, we can find one in a million cells in a patient’s bone marrow aspirate. So, it’s a very sensitive test, but it is not yet approved for making treatment decisions. One way we can use it though is for prognostic information. So, a patient attaining minimal residual disease-negative status or MRD-negativity, probably will do better than someone who has MRD-positive disease.  

And there’s an emerging concept called sustained MRD negativity. So, let’s take an example of someone getting MRD testing at one year and two years after their stem cell transplant. The patient who is MRD-negative at both the one-year and two-year marks will likely do better than the one who is MRD-negative at one year but turns positive at the two-year mark. 

So, these are some of the new developments in molecular testing in multiple myeloma.

Katherine:

What is MRD, and what does it mean for patients? 

Dr. Alsina:

So, MRD stands for minimal residual disease. So, it means that if a patient is in complete remission, what it would mean is that I don’t see any myeloma cells in the bone marrow and I don’t see an M spike. The M-spike is zero in the blood and in the urine, and the light chains are fine.  

But even with that, there maybe be some disease that is residual that I can’t see by conventional methods, so there’s two methods that have been developed that are able to detect one cancer cell in a million cells. 

Katherine:

Wow. 

Dr. Alsina:

So, if I have a patient that is in complete remission, I can use one of those methods to look, and that will tell me if the patient still has minimal residual disease or not. 

So, the reason why it is important is because there are many studies that have shown that if I can get a patient to be minimal-residual-disease-negative, no evidence of disease by those two tests – that I can explain a little bit more if you want – then those patients are going to do better, their response is going to last longer, and the patients are going to live longer. 

So, nowadays, with our better treatments, we use also that as a goal. We say okay, I not only want to get a patient in a complete remission, I want to get that patient to MRD negativity.  

And we do adjust our therapy to get there. As an example, I can do a transplant in a patient, and three months after transplant, I look at that minimal residual disease. If it’s negative, then I do Revlimid (lenalidomide) maintenance, which would be standard of care. If it’s positive, I use two drugs to try to get that patient to that MRD-negativity level, and there are many studies right now looking at how to adjust our treatment based on response.

Katherine Banwell:

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 Banwell:

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 Banwell:

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 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
