Lisa Hatfield:

So I just want to take a step back and kind of looking at this through the lens of a newly diagnosed CLL patient. You’d mentioned that sometimes you don’t treat every CLL patient. So is there something, if you find a patient who does not need treatment, is there something you tell the patients as far as regular monitoring? Will you monitor them to see if it progresses to the point where it requires treatment?

Dr. Ryan Jacobs:

Yeah. And we’re fortunate that this is a blood cancer that most of the time we can follow with a simple blood count and follow the white count, follow how the…follow the health of the bone marrow by looking at things like anemia, low red cell count, or a low platelet count that we call thrombocytopenia.

So that’s the easiest thing to follow, but I’m also talking with my patients and examining my patients. I want to know if their lymph nodes are causing them a lot of pain, because we should treat that, there’s no reason they should live in pain. I want to know if they’re waking up drenched in sweat all the time, if their quality of life has been really affected by that or a dramatic amount of fatigue that we can’t explain by some other cause. And I also, of course, examine the nodes myself and make sure that there are no alarming findings there. So that’s really what’s involved with checking on a CLL patient that’s on active surveillance, that’s what we call it. And there’s a list of criteria that the oncologist should know in terms of deeming who needs treatment and who doesn’t. And so we’re kind of following the same rules, so to speak, in terms of who gets treated for CLL.

Katherine Banwell:

How do you know when it’s time to change treatments? 

Dr. Raajit Rampal:

Well, I think really two things. One is if we aren’t meeting our goals like we just talked about. But the other aspect of that is if we are incurring toxicities that are just not tolerable to the patient and that’s a reason to change therapy always. 

Katherine Banwell:

Many patients, of course, worry about disease progression. Are there key predictors or tests for progression that patients should know about? 

Dr. Raajit Rampal:

This is a key area of investigation currently. I think one of the things that patients say to us so often when we meet them is what’s going to happen to me. And right now, we don’t have great prediction tools. We can say on a population level well, there is X percent of chance of progression at 15 years. That’s useful if you’re talking about a population. That’s not really useful if you’re talking to an individual. Because if I say to somebody there’s a 20 percent chance of your disease progressing to leukemia, it doesn’t really make a difference. That’s a meaningless statement because if you’re in the 20 percent who progress, it’s not a relevant statistic anymore. 

It’s sort of a binary thing. We’ve got to do better at developing this. This is something that the MPN Research Foundation is really heavily invested in in trying to identify predictive biomarkers. 

If we can do that, then perhaps what we can do is say to a patient this is really what we think your actual risk is. And then, the next step is asking the question if we intervene early, can we prevent that progression from occurring. So, that’s where I think we need to go. We aren’t there yet. 

Katherine Banwell:

What signs or symptoms do you look for that may indicate that the disease is progressing? 

Dr. Raajit Rampal:

The blood counts are often the canary in the coal mine regardless of the disease. They can tell us if ET or PV is progressing into MF or whether MF is progressing to more of a leukemic phase. Changes in symptoms sometimes can be a harbinger of disease progression. So, Patient 2, for example, is doing really well and now, he’s having drenching sweats and losing weight. So, those types of symptoms are a sign that physical findings is the size of the spleen if it’s increasing. All of those things together give us a hint about progression.  

Katherine Banwell:

Well, is there any way to prevent progression? 

Dr. Raajit Rampal:

That is the million dollar question. Again, that’s where we ultimately need to be. We want to be able to intervene to a point where patients don’t get that sick. It would be amazing if we’d come to the point where we can intervene early and nobody progresses to late stage MF. Nobody gets leukemia. And I think that’s a worthy goal. That’s not something that we should think is too lofty of a goal. That should be our ultimate goal here. And a number of groups are investigating this exact question. It’s complicated and it’s going to take time. But I think that’s a worthwhile investment.

Understanding and Managing Common MPN Symptoms and Side Effects


Transcript:

Katherine Banwell:

So, what are the types of treatments available for MPNs?  And let’s start with myelofibrosis or MF. 

Dr. Raajit Rampal:

If we had had this discussion five years ago, it would be pretty simple, and it would take a minute or two. And that’s completely changing and that’s amazing, and it’s good for all of our patients.  

Right now, for patients with MF, it depends on what the issue is. If the issue is symptoms or spleen, JAK inhibitors are our first line of therapy. Three approved JAK inhibitors are currently available, two on the first side ruxolitinib (Jakafi) and fedratinib (Inrebic). And pacritinib (Vonjo) can be used for patients with really low platelet counts.  

There is a fourth JAK inhibitor that we expect to be, hopefully, approved in June of this year, momelotinib. So, the landscape is about to complete broaden in terms of just JAK inhibitors. 

But beyond the JAK inhibitors themselves, there are a number of late stage clinical trials that are combining JAK inhibitors with agents that work through a different mechanism that don’t work through inhibition of the JAK pathway. So far, these drugs have all shown promise in early phase trials. Now, the definitive Phase III trials are being done. We have to wait and see what the data tells us. But if these are positive trials, this could completely alter the landscape of MPN. 

Katherine Banwell:

There’s also transplants available, right? 

Dr. Raajit Rampal:

Correct. Transplants for more advanced patients, which comes with some major risks. And so, that has to be thought of very carefully in terms of the risks and benefit. But it is a potentially curative strategy. 

Katherine Banwell:

Let’s turn to polycythemia vera or PV. What types of treatments are available? 

Dr. Raajit Rampal:

It’s really quite a range. So, there are things like phlebotomy and aspirin, which has been the mainstay of therapy for many years. There are drugs like hydroxyurea (Hydrea), interferons, JAK inhibitors. So, ruxolitinib is approved in certain settings for treating polycythemia vera. So, the landscape is broad. There are a lot of questions going on right now with polycythemia vera with regards to how it should best be treated. Is the mainstay of phlebotomy and aspirin really what we should be doing or should we be giving patients treatment earlier on. 

And there is some data to suggest that. There is this drug called ropeginterferon (Besremi) that’s FDA-approved for polycythemia, which was compared in the study to phlebotomy and aspirin.  

And at least the data suggests that there may be better control of the disease and less progression possibly, and it’s a small number of patients, by treating patients earlier. Whereas we would have just given phlebotomy and aspirin. So, it’s something to consider. There are drugs in clinical trials as well that look promising one of which is called rusfertide, which actually works by changing the way iron is used by the body. 

Iron is a key component to hemoglobin and it is, of course, a key component to polycythemia in the sense that we phlebotomize patients to make them iron deficient and that’s how we control the disease. But this is a pharmacological way to do that. So, that drug is now in Phase III trials. So, that may also alter the landscape of treatment of PV in the near future.  

Katherine Banwell:

Finally, how is essential thrombocythemia treated? 

Dr. Raajit Rampal:

So, in some cases, with absolutely nothing as we had talked about a moment ago. There is some thought that in really, really low-risk patients. Maybe you don’t need to do anything except observe them. Whereas most patients are on an aspirin. And beyond that, we have drugs like interferon, pegylated interferon, and hydroxyurea and anagrelide, all of which can be utilized. It’s not entirely clear if there is one distinct first line treatment that is the best but these drugs are all active. JAK inhibitors have been studied in this setting. And to date, the data hasn’t led to their approval but, certainly, people have studied it.   

Katherine Banwell:

Dr. Rampal, how can you tell if a treatment is effective? Are there signs that you look for? 

Dr. Raajit Rampal:

Well, I think it’s a couple of things.  

One, are we meeting the treatment goals in terms of are we controlling blood counts with ET or PV? That’s one of the first principles in management. And with regards to MF, the same thing. Are patients’ symptoms being controlled? Is the spleen being adequately controlled? And then, there’s the symptom burden because just because the blood counts are being controlled, patients may still have symptoms, in which case, they are not being adequately treated. And then, we have to do our best to try to find a treatment strategy that does control their blood counts but also does control their symptoms. So, there is the blood count perspective but there is the symptom perspective as well.

Lisa Hatfield:

Okay. So, Dr. Sirintrapun, the importance of connecting to specialized care when living with a rare cancer is so paramount. But with anything comes risk and rewards. What are the risks and rewards of telemedicine and maybe even some of the limitations? You both touched on that a little bit. But if you can talk about that a little bit, that would be great.

Dr. Sirintrapun:

Yeah, I’m so glad that Dr. Palmer actually illustrated to everybody, including myself, kind of how the processes work and if you had a trial, particularly with monitoring, and getting the right tests. So being a pathologist, that’s the other hat, I look at glass slides, but I also handle a lot of tests in particular, is looking at them. And in Memorial we do those complex humongous genome panels, it’s actually become much more commonplace to have 500 genes. And as Dr. Palmer had alluded to, sometimes you don’t know out of the 500, which are really meaningful, which are not. But out of that, you do know with some of them. I see it like the initial diagnosis, at least with technology, like the complex testing being done, still centered. It’s hard to outsource that to locally.

But in terms of convenience, I can see a future where a lot of these tests can be done more closer to the patient, where they’re simpler, there’s more automation. Somebody who might be a lab tech or nurse practitioner might, the instrument might be simple enough to press a button and you’ll get your results. And that’ll be just the right amount of genomes to monitor. Now going back to rare diseases and such, it depends on the rare disease. Because rare diseases have been kind of the classic paradigm for a clinical trial where you have to go to a centralized center because a lot of times the way rare diseases work is that they’re, at least in pathology, there centrally to an expert. Because there’s only one person that’s ever looked at it in the entire world and nobody else really knows. And you end up sending it to that guru.

And so the problem with that is that somebody has to know from the outside, “Hey, I think it’s this, I should send it to that person.” So you have, you already have friction and a gap right there. And you have the logistics of it just, okay, once it’s there and you get the diagnosis, what happens next? Can the patient who might be living from wherever be able to go and get enrolled in that trial? So you have all these different barriers that I alluded to before. So the advantage of the telemedicine is that you basically might have diminished the gap. You can bring that expert in terms of consultation to the patient who lives very far away. Now, going back to all the logistics about monitoring, if you had the right lab tests, and this is where the FDA comes in, and we don’t have time to go into the way lab tests are developed, but if the lab test is simple enough, you can do the monitoring more closer to the patient.

And in that way the clinical trial is much more enabling. They don’t have to fly somewhere, you have to go some…it all depends on how they can actually get the test to the right quality level and closer to the patient so that you can have the monitoring as more frequently and you don’t have the cost of actually having to ship either the patient or the sample elsewhere. So things that are changing, I’m hoping, because the technology’s there and it takes architects of clinical trials to rethink that. What’s the right technology now that we can apply it locally, so that we don’t have to do all this back and forth. And so that’s the type of thing. So going with the record, there’s lots of opportunity. I think the cautionary part would be is that tech, if you’re going to deploy something, let’s say near the patient, we call it point of care in lab testing, point of care, right?

Right, right near the patient. You have to make sure that lab test is quality, it’s actually good enough, like it met all the standards, and then you can trust the results. That’s the trick. And that’s where the cautionary part comes in. Are these things really good enough that anybody with a little experience can use it and that people can interpret the result and you can trust the result. That all these things are in place. I’m giving you the ins and outs with the way, when you want to deploy something, these are the different things you have to consider. But there’s a lot of potential as I mentioned. 

Lisa Hatfield:

Sure. Great. Dr. Palmer, do you have anything that you want to share or add to that? Risks, rewards, limitations for MPN patients about telemedicine?

Dr. Palmer:

So, I think that brought up a really good point. So when we look at these tests that you can order, I think there’s a lot of companies that do very reputable tests that are even sometimes utilized by some centers. And so at the first diagnosis, I think there’s the piece that what is going to help clinically based on the knowledge that we know, and that is some of these tests that actually can, are very good quality have somebody to be deployed, draw the blood, send it to wherever and do the test. Sometimes it’s good to be at the center itself where there’s actually labs and that increases the learning. I think that the architecture of the clinical trial which was a great way to put it, is going to be really important, because if I take a complete blood count, honestly, I mean, anyone can do a complete blood count and I can get the information that I really need to get out of it.

If we look at drug levels, that’s a far different animal is to make sure that these drug levels get drawn in the right way at the right time, sent to the right place. That can be a real challenge. So there are going to be different aspects of the clinical trial that can and cannot be done virtually and through outside resources. So I think that, that it’s certainly not all created equal. So there’s no way I can do the entirety of a clinical trial without physically having a patient at the center. However, on the other side of that coin, I think there’s probably a number of things, especially with like really routine visits where we’re not getting drug levels, we’re just checking a CBC, or a complete blood count or chemistries or something in the blood, that that can probably be done almost anywhere.

So it’s just going to take an extra layer of thought. I think that a lot of times you use what you know, so you say, “Well, this is how this clinical trial was run and they have to come in and they have to get an exam and they have to get a CBC and they have to get everything else.” I think that there’s going to be ways that we can alter that to really think what are the meaningful things we need? Like we don’t use every single solitary time point, What are the safety measures we need to make sure we capture? So it is going to require sort of a lot of thoughtful processing to figure out how to do that. The other thing to be cautious about is if you have the interpretation of the test.

So let’s say I send out a lab to one of the companies that does really extensive panels of genes, and then it goes back to their primary provider. They might look at that and go, “Well, geez, I don’t know what any of this actually means.” I mean, frankly, out of those 400 genes, there’s a number of them that I don’t even know how to interpret. I say, “Well, this is interesting, but these are the ones that I know are really critically important and can impact your, what I anticipate is going to happen to you. But some of these we don’t know yet.” I mean, I think that’s what we’re learning about. So doing these tests, sometimes getting these big panels can be confusing and frankly scary if you don’t have somebody there who is able to say, “Yes, these are the important ones. These are probably not that important. So it’s interesting that you have them, but we don’t need to worry about them right now.”

And so that’s really key, because otherwise you start to go to Dr. Google and, which is not anybody’s friend, and get yourself really terrified. So I think that that ability to put things into perspective is also, and have the ability to incorporate it into the education given and the treatment plan is really critical. So again, a hybrid model is really necessary for a lot of these to work well. And how that hybrid model works is going to be dependent on the disease type, the clinical trial in that situation. But I think that there’s ways to do it, and I personally in my own practice have created a set of rules that I’m like, “Okay, well, for this and this and this and for this you have to do that and I need to do this.” So I have certain things set up to make sure that I feel like I am providing safe care, but also being able to provide it virtually.

Laura Beth:

Dr. Ravandi, does maintenance therapy have a role in AML?  

Dr. Ravandi:

Maintenance therapy is something that has been used in other leukemias for a long time, and other types of cancer, particularly in ontological cancers. In AML, it hasn’t been normal practice, traditionally, mainly because in AML, we haven’t had many good relatively nontoxic, easily taken drugs.  

So, about 30 years ago, some groups, for example, a German group actually tried to do maintenance with cycles of chemotherapy, and you can imagine if a patient is in remission, and somebody says to you, “I’m going to give you cycles of chemotherapy for the next three years,” most patients wouldn’t take it because they say, “Well, you know, maybe I have three years to live. I want to go to Bahamas and be on the beach rather than getting cycles of chemotherapy.” But over the last several years, in a number of effective, highly effective oral agents that have been developed, and one specific agent that has been developed for maintenance. Now, this specific agent is not curative, as it’s not that if you take it, you will live forever.  

But it does improve survival, and it’s relatively well-tolerated. And there are other clinical trials of maintenance. Agents are being developed, and I think it’s a very important area in AML. And I think in the next several years, it will actually become common practice to do maintenance regimens.  

Laura Beth:

That’s good news. So, once an AML patient is in remission how are they monitored? 

Dr. Ravandi:

So, I mean, I usually tell my patients that once you’re in remission, you’re in remission until something goes wrong with your blood counts. So, in my opinion, it’s not important to do – definitely not important to do weekly blood counts, for example.  

Depending on patient’s anxiety levels and comfort, we do check their labs maybe once a month, once every two or three months, depending on how far they are from their remission. And in my opinion, routine bone marrows are not necessary during remission, unless the patient is a part of a clinical trial that they have accepted to participated in, because we do get a lot of information by doing those bone marrows. So, some studies have follow-up bone marrows, but that’s really as a part of a clinical trial and to help further the knowledge in therapy.

Understanding Treatment Options for ET, PV, and Myelofibrosis


Transcript:

Katherine Banwell:

Okay. Katie had this question. “What are the signs of progression from PV to MF or AML, both clinically and in blood tests, and when do you need a new bone marrow biopsy to check for this happening?” 

Dr. Jeanne Palmer:

So, in terms of progression, there are several things that we see happen. 

I think most importantly is, let’s say you have PV, and you’ve always been on medication, and it’s been hard to control. And all of a sudden, you don’t need medication to control it anymore, or the same thing for essential thrombocythemia. You have been taking medication, and all of a sudden your platelets go down, and you don’t need to take drugs anymore. A lot of times people are like, “Oh, that means I’m fixed and I’m well,” not necessarily, you really need to make sure to talk to your healthcare provider and potentially get a bone marrow biopsy. 

Now, the other thing – sometimes the blood counts will actually drop too low, so you’ll have somebody who has PV, who has always been too high and then all of the sudden they come in, and their hemoglobin is very low, and they’re anemic, and that’s another situation where you do that. So, anytime the blood counts start to drop is concerning. 

Now, it’s a continuum, so the blood counts may drop as you’re at the point of transitioning but it doesn’t – it’s not like if your blood count is dropping you say, “Oh my God, I have myelofibrosis, I need a bone marrow transplant tomorrow.” That’s not necessarily the case. This is generally a transition type process. 

Also when the spleen starts to get enlarged. Now, the spleen can be enlarged even in the setting of just ET or just PV, so spleen enlargement does not necessarily mean you’re transforming, but it can be one of the things that we would see that would indicate that. 

Katherine Banwell:

Okay. 

Dr. Jeanne Palmer:

And then finally white blood cell count increasing can often be a sign of that. Now, in terms of progression to AML, that is generally something we’ll see in the blood. AML or acute myeloid leukemia, is indicated by the presence of blasts at greater than 20 percent. Now, many patients with myelofibrosis, in particular, but even PV and ET, may have blasts in their peripheral blood. Blasts are normal. If I did a marrow on every healthy person out there, they are going to have some blasts, because these are the first part of the development of white blood cells. So, they’re like baby white blood cells. But what the problem is, is when they start to grow too much. 

And so in the setting of myelofibrosis and even sometimes with these other diseases, the blasts will be in the peripheral blood primarily because the bone marrow is damaged and doesn’t hold them in very well. It becomes AML when it gets greater than 20 percent, so that blasts of greater than 20 percent in the peripheral blood or in the bone marrow but a lot of times we find it in the peripheral blood is where we indicate this has progressed to AML. 

Katherine Banwell:

Yeah.  

Dr. Jeanne Palmer:

Blasts of greater than 10 percent are also something that we really want to pay attention to, because that would suggest that the disease is starting to become more aggressive. Now, blasts vary, so for example, I’ve had patients go up to 11 and then drop back down to 3 or 4, and then they say around 3 or 4 or 5. So, you always want to make sure to double-check because one blast count at 11 percent, whereas it’s very important to address, may not necessarily reflect that you need to change in treatment at that time. Again, these blood tests, I always tell people, do not freak out over one blood test. 

Make sure you get at least a couple of them to really confirm what you are looking at.

COVID-19 Vaccination: What Do Myelofibrosis Patients Need to Know?


Transcript

Katherine Banwell:

Once on therapy, how is the disease monitored and how do you know if the treatment is working?

Dr. Pemmaraju:         

So, it differs from each disease, but let’s take polycythemia vera for a good example. So, let’s suppose you have polycythemia vera. I think there’s three markers here that you can check. One is the blood counts, right?

So, you want to make sure that the blood counts are controlled. New England Journal, five or six years ago now, our Italian colleagues published a very seminal paper which shows that the goal of therapy should be that the hematocrit should be below 45. So, that’s actually a very nice number to have. So, not just waiting for symptoms of the disease but keep the number low. And if you do that, that correlates with decreased cardiac events, thromboembolic events.

Number two, I think that, besides the blood count, the spleen. The spleen and liver size also is a nice surrogate for how the disease is doing. So, if that’s enlarging or getting out of control, that may be time to stop what you’re doing, reassess. The disease may be progressing to myelofibrosis, for example.

And then I think, lastly, the absence of stuff actually helps, too. So, the absence of major bleeding, the absence of blood clots, the absence of transformation to MF. I think if the quality of life is good, you’re decreasing blood clots and bleeding, you’re not going to a more advanced disease state, these are all wins for us with P vera.

Katherine Banwell:    

You touched on this briefly, but I’m wondering when a patient should consider changing treatments.

Dr. Pemmaraju:      

Yeah, changing treatments is more art than science, I would say. So, it does – that’s one of those that is kind of specific from patient to patient. In general, what we just talked about gives you that guidance. So, in polycythemia vera, since we brought that up earlier, uncontrolled blood counts despite maximum medication intervention, the phlebotomy requirement being untoward and impossible to keep up with, the spleen size growing out of control, the quality of life being impossible – these are some aspects to look into changing therapy and/or clinical trial.

But remember, it’s not a one-size-fits-all, right? So, some patients, the counts – some of these things may or may not actually play out. So, it has to be more of a gestalt, more of a total picture there.

What standard testing follows a myeloma diagnosis?

Dr. Richter:

So, the standard testing that follows a myeloma diagnosis is multifaceted. So, the first one is blood work. And we draw a lot of blood tests to look at the bad protein that the cancer cells make. So, we send tests like a protein electrophoresis which tells us how high that bad protein is. We send immunofixation. That test tells us what type of bad protein it is. You’ll hear names like IgG kappa and IgA lambda.

These are the different types of bad proteins made by myeloma cells. Oftentimes, we’ll send urine tests to find out how much of that bad protein that was in the blood is coming out in the urine. We will, typically, do a bone marrow biopsy. It’s a test where we put a needle into the back of the hip bone to look at the marrow itself. And we’ll use that marrow to figure out how much myeloma there is, any other characteristics like the genetic changes in those cells.

The other big thing is imaging. So, the classic imaging that we do with myeloma is something called a skeletal survey. It’s, basically, a listing of X-rays from head to toe. But nowadays, we have newer techniques, things like whole body low-dose CAT scans, something called a PET-CT scan, and MRI scans. And your care team may have to figure out which one is right for you at what given time.

Katherine:

Mm-hmm. Are there additional tests that patients should ask for?

Dr. Richter:

Absolutely. One of the most important things from myeloma has to do with the genetic risk stratification.

So, for almost all cancers, the staging has a very big impact. And people will often think of cancer in stages I, II, III, and IV, and they’re managed very differently depending upon what stage it is. Myeloma has three stages, stage I, II, and III. But the most important thing is, actually, beyond the staging is what’s called the cytogenetics risk stratification. So, it’s really important when the bone marrow is sent to be sure that it is sent for, kind of, advanced techniques. Because you really want that snapshot of exactly what the genetic profile is, because that gives us information of A) how to treat, and B) prognostic, you know, who will tend to do better or worse based on this information. And even though that may not tell us which drugs to use, specifically, it may say, should we do something like a transplant or not? Should we consider a clinical trial early or not?

Katherine:

I see. How do test results affect treatment choices?

Dr. Richter:

So, test results can affect treatment choices in a number of ways. Probably, the most common one is thinking about the routine blood tests like your CBC or complete blood count and your chemistry, which looks at things like your kidney function. Some drugs tend to have more toxicity to the blood counts. So, if your blood counts are very low, we may choose drugs that don’t lower the blood counts very much.

Kidney function which we, usually, measure by something called the creatinine. Creatinine is made by the muscles and cleared out by the kidneys. So, if your kidneys aren’t working very well, you don’t pee out creatinine, and that creatinine level will rise in the blood. If your creatinine level is high, we may choose certain drugs that don’t affect the kidneys or not metabolized or broken down by the kidneys.

The genetic studies that we use – we’re not quite at this base yet where we can say, if you have this genetic abnormality in your myeloma, we should use this drug except there’s some really great data on the cutting edge about a drug called venetoclax.

Venetoclax is a pill that’s used to treat other diseases like lymphoma and leukemia. And it turns out that people who have what’s called a translocation (11:14) which means part of the 11th chromosome and part of the 14th chromosome in the cancer cells swap material.

Those people respond amazingly well to venetoclax. So, we’re starting to have what we would call precision medicine where we find your genetic abnormalities, not that you got from your parents or passed to your kids, but the genetics inside the tumor cells to tell us which treatments will work best for you.

Katherine Banwell: 

What testing should take place following a myelofibrosis diagnosis? 

Dr. Scandura:  

So, a diagnosis of myelofibrosis always comes after a bone marrow exam and a physical examination. Often, patients have an enlarged spleen and blood count testing and a variety of other laboratory tests. So, after that and a diagnosis is made of myelofibrosis and, sort of, coincident with the diagnosis, we often look for molecular markers of myelofibrosis. So, these are malignancies of the bone marrow, cancers, if you will, on the bone marrow, although the term is scarier than or is different than what we think of for many malignancies in how it acts. But the myelofibrosis, this is a disease that’s characterized by, really, mutations in the malignant cells, the abnormal cells. 

They’re really just one of three genes. And so, JAK2 being one of the genes, calreticulin or CALR being another one, and MPL one.  

And more than 90 percent are people having mutation in just one of those three genes. And so, often at the time of diagnosis, tests for those mutations are done, and they help eliminate the possibilities of other causes of myelofibrosis – infections, rheumatological diseases. Sometimes, you can have marrow fibrosis but they don’t go along with mutations and the same clinical situation. And so, at the time of diagnosis, we usually know something about a mutation in JAK2, CALR, or MPL.    

More commonly now, and it’s increasingly common over the past 10 years in, I would say, in New York City and many places across the country, we also look more broadly for other common mutations in the MPN cells. And these are what we refer in the batch as next generation sequencing or NGS panels, and we use the term panels because we’re looking at from a few tens to even 100 or a couple hundred genes for mutations that occur far less frequently than in JAK2 or MPL or CALR.  

But they occur often enough that some of them we use to help guide treatment decision-making or approach to therapy. The reality of it is that that the technology to sequence and identify mutations has really outstripped our knowledge of what to do with all of that information. 

And, for the vast majority of people, it comes down to do you have a marker, a genetic marker that tends to go along with higher risk, meaning a higher likelihood of something that we don’t want to have happen. And in that instance, although it may be looking at a hundred or so genes, it comes down to a binary thing – either you have or you don’t have. 

Katherine Banwell:

Is there any other testing that you usually want to do? 

Dr. Scandura:

Laboratory testing, for sure and, as I mentioned before, a bone marrow exam. But physical examination, some people might do imaging of the spleen size. Honestly, I don’t routinely do that outside of the setting of the clinical trial. I don’t really think it dictates therapy very often. 

And if the spleen is so small that you can’t feel it on physical exam, it probably isn’t clinically meaningful anyway in terms of something to treat. It might be there, but it doesn’t really change things too much.   

Katherine Banwell:

How often should patients have a bone marrow biopsy? 

Dr. Scandura:

So, I’ll answer there is no standard in terms of monitoring for myelofibrosis with the marrow or otherwise. My personal approach is I do a marrow when I think it’s going to help medical decision-making. And so, for a patient who’s got early myelofibrosis, who’s been very stable, responding well to therapy, that could be three, five years between marrow exams. 

For somebody who’s being considered for a clinical trial, oftentimes, a marrow exam is required before they start on the clinical trial and at various intervals afterwards. If there’s somebody who had been stable and something is changing, like the blood counts are changing or his symptoms are changing, or any of a number of clinical features, then I might look in the marrow to see what’s happening there, to see if explains and can help guide a treatment approach to help people feel better. So, there is no single standard, but my personal approach is to do a bone marrow exam when I think it’s going to help make a decision.

Dr. Michaelis:             

So, the regular follow-up for myeloproliferative neoplasms, whether that is somebody with ET, PV, or myelofibrosis, is incredibly variable. It depends on the risk stratification. It depends on how frequently you’re needing intervention.

For example, somebody with low-risk polycythemia vera whose hematocrit is elevated and gets a phlebotomy – that person I follow relatively frequently.

Maybe every month or so until I know for sure that the phlebotomy frequency, the number of times we are removing blood, and the frequency, the rate at which that happens, is adequate to ensure that that person is not spending too much time with a hematocrit of over 45 percent.

We know that because randomized trials have shown that a hematocrit over 45 percent leads to an increased risk for bad clinical outcomes.

So, early on in that person’s trajectory, I might check their blood counts more often. Once I know that they are stable and can go longer periods of time, we can relax that out. And that may happen, for example, when they become iron deficient, and the need for phlebotomies decreases.

In somebody with essential thrombocythemia that’s well controlled, again, one might do blood counts every three months or maybe, if things are very stable, every six months.

This is something that I usually make sure that I’m following the national guidelines on and that I adjust from a patient standpoint. If somebody is seeing their PCP in three months and getting blood counts, and things have been stable, then there’s no reason to see more frequently.

Now, when do I see people more frequently? For example, if they’ve started a new treatment, and we want to make sure that their kidneys and liver are doing okay. If I’ve noticed a change in one of their organ functions on the basis of something and do a little tweaking of their medicines, then I might see them more frequently.

So, again, there’s no set-in stone. This is part of the art of medicine, and you wanna talk with your doctor about what you should expect and who’s gonna be following up on the tests that are drawn.
