Essential Thrombocythemia Watch & Wait | What Patients Should Know

Essential Thrombocythemia Watch & Wait | What Patients Should Know from Patient Empowerment Network on Vimeo.

What is watch and wait, and what does it mean for essential thrombocythemia (ET) patients? Dr. Naveen Pemmaraju defines this term, helps viewers to understand why it’s beneficial to wait before beginning treatment, and shares advice for managing the worry that can be associated with this time period.

Katherine Banwell:

Stephanie writes, “I have ET, and I’m not being treated. Do you have advice for the watch-and-wait period? I’m anxious about the disease changing and don’t know what I’m waiting for.” So, before you answer the question, Dr. Pemmaraju, would you define this term, watch and wait?  

Dr. Pemmaraju:

I will. And to Stephanie and everyone out there, this is a great question. I will say half the folks I talk to actually call it watch and worry, okay. Some people call it watch and wait, and as Stephanie’s saying, some people call it watch and worry.  

Yeah, the concept is threefold. One is that there are many cancers, many cancers, including blood cancers, that can be caught so early on that they don’t require treatment. A lot of patients with CLL, chronic lymphocytic leukemia, ET, as Stephanie mentioned, in the solid tumor. It’s very common to be diagnosed with a prostate cancer that’s low grade, early stage that can be observed. Number two is in ET, there is a science behind it.   

What we found in our studies, and they can be updated over time and you’ll see those, the traditional is that if you’re below the age of 60 and/or you’ve had no blood clot, thrombotic event, that’s considered low risk. And the treatment can be observation, perhaps adding in a baby aspirin to prevent against blood clots if there’s no contraindication. Now what’s magic about that age 60, obviously as you know, it’s not magic. It’s more of a statistical, continuous variable algorithm that says around that time, the risk of blood clots goes up.

And so then you’d consider cytoreductive therapy at that point. Now there’s exceptions to that. Many of our young patients are on therapy, but there’s usually some reason for that. Some high-risk feature, wildly uncontrolled blood counts, for example, symptom burden, some other high-risk features. So, it’s a suggestion. It’s a guideline, not an absolute. And then the third part of it is, the what do you do in that time? And that’s the frustrating thing. And I think that’s what Stephanie’s getting to.  

Again, that’s why I said the watch and worry versus watch and wait. Some of it is, how are you feeling outside of this? Some patients take it as a great news. Hey, you have this blood cancer, that’s not good news. But the good news is it’s probably not going to be active for a long time, we can, “just watch it.” But some people, as Stephanie is saying, take it the opposite way. What do you mean I got a blood cancer? I got something lurking in my body. You’re telling me it’s there, you know it’s there. And so what’s up with that? And the concept there is that some of these situations like low-risk ET, we found that if you treat too early, too aggressively, you can actually do harm.  

So, that’s the key. These chemo drugs are not benign as you had me discuss earlier. They have toxicity, side effects, short-term, long-term. So, it’s a risk-benefit thing. If the risk far outweighs the benefit, as in the younger patient with no symptoms, no high-risk features, observation is okay. But at some point, when it turns, that’s the threshold.  

So, really the key is, if we believe these are stem cell blood cancer disorders, we need to be thinking about and designing therapies with minimal to no toxicity. Something that actually modifies the disease early on and something that leads to long-term outcomes. And we don’t have that yet in ET. We’re working on that in PV and myelofibrosis. So, stay tuned for that.

And then finally, let me also add, this is an important point, not everybody gets it. This watch and wait versus watch and worry. So, I’m glad Stephanie brought that up because it’s not always good news, uniformly, when you tell someone, good news is you don’t have to do anything bad news, there’s something there. 

Expert Advice | Strategies for Managing MPN-Related Fatigue

Katherine Banwell:

Well, it’s obvious that there’s some symptom overlap along with this.  And so I’m wondering what the strategies are for managing these. Let’s start with fatigue first.  

Dr. Pemmaraju:

Let’s do that.  

Katherine Banwell:

How do you manage that?  

Dr. Pemmaraju:

This is one of the tougher parts of what we do. I’m glad you’re pinning me down to say it, because really this is the majority of what we need to be talking about in the clinic. I’m going to just be honest, you know, with all the scientific breakthroughs and everything, some of these are limited. The fatigue, this is some of the strategies I use and some of the experts in the field. I think one is managing the underlying disease. So, as you mentioned, if you have high-risk, intermediate to high-risk myelofibrosis, one of the great findings of our field is the JAK inhibitor class generally helps to improve symptom burden.  

So, that is the splenomegaly, the fatigue, the pruritus. Maybe not so much the itching, but some of these other things. So, I think treating the underlying disease, that’s okay. Number two is many clinics, onc centers around the country are starting to open up a supportive care or fatigue center clinic. So, I am referring several of my patients there, we’re talking about diet, nutrition, exercise. We used to never talk about these things. Ruben Mesa has found that doing yoga and meditation can genuinely actually help the pathobiology to reduce the cytokine storm and improve the fatigue and quality of life. 

Dr. Angela Fleischman, our colleague at UC Irvine, has done work suggesting that possibly an antioxidant diet such as the Mediterranean diet can help the overall general fatigue, well-being, wellness. And then of course I mentioned earlier, but I’ll mention here too, sometimes fatigue is outside of the MPN. Have you had your TSH or thyroid checked? What about your vitamin D levels? How are you doing on these PCP general checks? Things that may be contributing to the life and the happiness.

And finally, let me make a plug for mental health. I don’t know how much we were emphasizing before the COVID pandemic, but after, the last three or four years have been tough. Healthcare providers, caregivers, patients themselves, mental health checkup, that can also be contributing to fatigue, not getting out of bed, in addition to the organic medical problems. So, let me advocate a multifactorial approach, scientifically summed up as treating what you can with the underlying MPN, fine, treating the side effects and symptoms of the MPN, as you said. 

And then, other, which can be a huge bucket, particularly as we get older, to not forget about that. Again, checking the thyroid level. And then when you’re on these different treatments, you can personalize it. Interferon, obviously, has its own separate set of side effects and then of course the other agents. So, I think that may be the best way to approach it. Maybe a three-bucket approach. The MPN itself, and then the treatment itself, and then the other, something like that.  

Katherine Banwell:

And as you’ve mentioned, it’s all going to be personalized and individualized.  

Dr. Pemmaraju:

Hugely.   

Katherine Banwell:

Right, because what’s going to work for one person is not necessarily going to work for another.  

Dr. Pemmaraju:

Hear, hear, well said to that. You know, you think you make a great diagnosis in the clinic, someone’s having fatigue, they’re on therapy for your MPN. You check the TSH, it’s wildly abnormal. Okay, you refer them to endocrine. Six months later, the thyroid level is completely normal now on thyroid medicine. And yet, the fatigue, brain fog, everything is still not clear.  

The MPN is under good control. What gives? That’s the difficult part of these diseases. So, I really love what you said about the personalization and to keep looking and keep trying.

What Are the Beginning Stages of Multiple Myeloma (MM)?

Where Should I START Following My Myeloma Diagnosis

Transcript:

Healthcare professionals use a combination of lab test results, imaging tests, and bone marrow exams to determine the stage of multiple myeloma. The revised International Staging System or Durie-Salmon Staging System may be used in determining a patient’s multiple myeloma stage. 

Dr. Abdullah Khan:

The patients are assigned stages I to III. To determine the ISS you need lab values for the beta-2 microglobulin and albumin. For the revised ISS, you add on the lab value for LDH, lactate dehydrogenase, and you also add in the chromosome risk profile. So, there are certain genetic changes that predict a more aggressive myeloma. And the ones added to the revised ISS staging system are translocation 4;14, translocation 14;16, and deletion 17p.” 

Lisa Hatfield:

So staging with multiple myeloma is really unique. A lot of times people think that every cancer has four stages. That is not true with myeloma. There are three stages for myeloma. And even now as of this year, some providers, some oncologists are not even staging myeloma. They’re looking at the risk factors, the cytogenetic risk factors to see if you’re standard risk or high risk. They’re not even using the staging system. It’s interesting. Back when I was diagnosed back in 2018, there were two staging systems used. One was the Durie-Salmon scale. I was diagnosed as stage III, which is the highest level. Mine was based on the fact that I had a lot of bone lesions and bone involvement.

But there’s also one called R-ISS, the revised ISS staging. And that one I was staged at stage I. So it’s really important to get a myeloma specialist on board quickly, because my myeloma specialist explained why I had two different stages I was staged at. She used the R-ISS, the more current system, the stage I and also looked at my cytogenetic risk factors. So your doctor will talk to you about FISH testing. And FISH testing might show something like translocations in the myeloma cells themselves or genetic abnormalities in the myeloma cells themselves. And that helps them dictate also what your risk will be going forward and how to treat that, how to treat your myeloma as a result of those risk factors and the stage you’re diagnosed at.

Your care provider may use other criteria in determining a person’s best optimal treatment. Make sure to ask if you have additional questions.

Transcript:

Katherine Banwell:

Is there research being done on MPN progression to understand how it happens or even prevent or slow progression? 

Dr. Scandura:

Yeah. There’s a lot. I think there is a – from both the sort of basic laboratory using animal models to try to understand what are the kind of systems that are involved in how these diseases change. What genes are involved? How do they talk to each other? You know, these are not cells that live in a vacuum, right? They live in a special microenvironment. What are the signals that crosstalk between the MPN cells, the MPN stem cells, and their microenvironment?  

And so, there’s a lot of research on that and the basic side of things. In humans, there’s a lot that has been done over the years in terms of trying to understand what are some of the genetic features of progression. And I think we’re beginning to get a little bit of a better understand of what are the non-genetic things that are associated with progression.  

I was part of an effort from the MPN Research Foundation and still am.  

They have what they call the Progression Network, where they tried to put together a number of investigators from really across the world to share ideas about the nature of progression and how we might look at studying this and understanding ways to prevent progression.  

I think we do have some drugs now that show some promise in terms of being able to prevent progression. I think interferons have shown this in polycythemia vera in terms of a promise for improved long-term outcomes and delayed risk progression. I think that the gold standard randomized trials are maturing and are sort of bearing out some of the same findings that have been observed retrospectively, so sort of kind of looking back in time.  

But the difficulty is that it can take a long time for patients to progress. And you say, “Oh, that’s great.” And that is great. But, from a research – from a statistical side, it means things are really slow. If you have to wait 15 years to assess whether or not people progressed less in one treatment versus another, it’s really slow going. And so, we have to do a compromise of what’s – you know, what do animal studies say? What does retrospective analysis, when we might have people who started treatment 30 years ago, and now we’re just seeing how did it all work out? It’s not a perfect study, because biases can creep in, but it’s what we have now. And so, there’s a lot. And I think, increasingly, progression is being recognized as a goal of therapy, to prevent progression.   

Personally, it is one of my major goals, because I think we do a pretty good job at preventing clots with available treatments. But I don’t think we do a very good job at preventing progression, mostly, because we don’t exactly understand what’s driving that. And so, I think until we develop that deeper understanding and really invest the time and effort in terms of learning which approaches can help prevent progression, we’re going to continue to have these questions.

What Standard Testing Follows a Myeloma Diagnosis?


Transcript:

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.

Myeloma Treatment Decisions: What Should Be Considered? 


Transcript:

Katherine Banwell:

What is cytogenetics, and how is it used in myeloma patient care?

Dr. Shah:

We use the term cytogenetics and FISH sort of interchangeably, and really what it is, is the DNA characteristics of the bad plasma cells. So, the myeloma cells, and a lot of them may have changes in their DNA that are what we call clonal, meaning that they’re in a significant percentage of those cancer cells, or they might be non-clonal, which are less significant. But it’s the way the DNA is put together or maybe cut and pasted so that it changes the characteristics and maybe the aggressiveness of the disease.

Katherine Banwell:

What is the goal of this in-depth testing? Are there specific markers you’re looking for?

Dr. Shah:

When we look for things like cytogenetics and send FISH testing, we look to see if patients have changes that might make their disease may be more aggressive.

For example, it may cause their plasma cells, the myeloma cells, to grow faster or more aggressively. So, we look for changes that might, for example, have a deletion of a certain chain that puts the brakes on tumors, or it may have a translocation, which is when the chains sort of do-si-do together and that makes the cells grow faster.

Transcript:

Katherine Banwell:

What are the main factors that you take into consideration before a treatment approach is decided on?

Dr. Shah:

We always have to remember that treating a patient is also treating a person. So, it’s not just about what the disease the patient has but who the patient is. And so, we take into consideration goals that the patient as well as other health factors that may take – be taken into consideration. For example, the patient may have high blood pressure or a heart condition. But regarding the disease, we really also take into consideration what the profile of the disease is, maybe how much disease burden the patient has and some genetic factors that may impact our decision-making.

Katherine Banwell:

What is the patient’s role in treatment decisions?

Dr. Shah:

The patient should always be the center of the decision-making. I think that’s a really important thing for us to remember because ultimately, it’s the patient who has to make the decision and has to withstand the treatment. Alongside of that there may be some caregivers as well, but the patient has to, 1.) understand the disease, and 2.) understand the treatment options. So, it’s best if the patient has as much information as possible.

Katherine Banwell:

Are treatment considerations different for patients with relapsed disease?

Dr. Shah:

For patients with relapsed disease, there’s a lot of things to consider that may not have been true when the patient was first diagnosed. For example, you always have to think of what maybe the patient had as a prior – excuse me, as a prior treatment, and also how the patient tolerated it.

Transcript:

Katherine Banwell:

Why should a patient consider participating in a clinical trial?

Dr. Shah:

I am a huge fan of clinical trials, as you probably figured out. And the reason for that is that it’s the only way we know how to do things. And for everything we figured out about myeloma, it’s because patients participated beforehand in clinical trials. So, of course, it’s a way to pay it forward. But aside from that, there’s an experience that a patient can have on a clinical trial that is really unlike other experiences that patients may have. For example, they will be given the opportunity to understand a lot about their disease that maybe they may not have understood before, and they may have the opportunity to try a treatment that might be beneficial.

There are no guarantees in a clinical trial, and that informed consent procedure where the doctor tells you about the risks, benefits, and alternatives, should be very comprehensive and clear. But it does allow for patients to get access to something they may not have had before. And I think one of the other things that’s important is that it’s sort of a concierge service, I would say, with clinical trials, because you have to be monitored very closely. So, of course, all your symptoms have to be known. And you get a little bit more time, I would say, when you participate in a clinical trial because we really want to know the pluses and minuses of these treatments.

Katherine Banwell:

How can patients participate in research? Where do they start?

Dr. Shah:

Participating in research is a great opportunity for patients and something that we’re grateful for as myeloma physicians. There are many ways to look on various websites. There are things like SparkCures. There’s ClinicalTrials.gov. You can look at any academic website. Almost all advocacy groups also have opportunities for you to look at clinical trials.

And any time you get the opportunity to look at patient education sites, they may have a link for you to look for other clinical trials that might be relevant to your particular stage in disease or the particular kind of myeloma that you have. When in doubt, please, if you have a chance, talk to your local oncologist perhaps to maybe refer you to a myeloma specialist. We can do this by Zoom now, so there should be no reason that we can’t be a part of your care team at least for a consultation.

Katherine Banwell:

Is there emerging myeloma research that you feel patients should know about? And what are you excited about?

Dr. Shah:

There are so many aspects of myeloma treatment and the patient’s journey that we have been looking at. One of the things that I’m most excited about and I do a lot of research in is immunotherapy, which includes both CAR T-cell therapy as well as natural killer cell therapy and bispecific T-cell engager and other novel immunotherapies.

And I think these are interesting, because they allow for the patient’s own immune system sometimes to be used to kill the myeloma. And that’s something that is spring-boarding the way we treat myeloma to give patients better outcomes with less toxicity, if you can believe that. So, we’re really excited about that.

The other thing I’m really excited about is patient experience research that we’re doing. We now know that multiple myeloma patients live for maybe over a decade, and those patients are on a marathon of treatment; and how that treatment is a part of their life is very important in their experience as a patient. So, we’re trying to make that easier for patients as they go through, for example, transplants or maybe immunotherapy to give them more information, more control and more ability to talk about their symptoms with their provider and their care team.

Katherine Banwell: 

Some patients may not know if they’ve received these important tests. So, what key questions should they ask their physician about testing?

Dr. Mascarenhas:       

Well, I think it’s important that the patients feel empowered to understand sort of where the field is and what key questions you would ask a physician, hematologist who’s taking care of you. So, I think all patients should be aware of their diagnosis, the name of the diagnosis, the subtype, but also do they have any of the key driving mutations, the JAK2 mutation, the calreticulin mutation, the MPL mutation, and that’s usually done off of a bone marrow biopsy sample, but it can be done off peripheral blood. And, they may not always know that it’s done. So, I think having a discussion with the position to understand there are criteria that exist called the World Health Organization criteria that are updated frequently and should set a standard throughout the world of how you diagnose and establish these diagnoses.

So, I think it’s important for physicians to be able to convey to the patients with confidence, “We follow these criteria and you have these criteria and we’ve done this testing that shows that you have these mutations.” And not just regurgitate what they found, but help them understand and navigate with that means, which again, I will point out that sometimes we don’t know. But, I think it’s important for physicians to convey sometimes that some of the findings that they may see, for example, patients look on portals these days and they can look at their labs and stuff like that. And, we don’t always have a terrific answer or an informed answer for everything that we get back. And, we will potentially in 10 years from now, but sometimes at the moment, we don’t. But, I think a discussion about the meaning of the labs that are obtained is probably good for the patient to understand what’s being done.

Katherine Ba:nwell:

Absolutely. It sounds like each person’s situation is unique and should be considered before making any treatment choices. Can you talk about how the results of these tests may affect prognosis and treatment?

Dr. Mascarenhas:     

So, we do have risk stratification systems that we use for essential thrombocythemia, polycythemia vera, and myelofibrosis. I’ll talk about myelofibrosis because that’s probably a little bit more of a complex and sophisticated model. It’s also changing, and we update it frequently. And, these models are imperfect, so I always warn patients to not put all of their money in one basket when we talk about risk stratification. They broadly help us understand where a patient is in their disease course. So, for example, in myelofibrosis, historically, the DIPSS, the Dynamic International Prognostic Scoring System is used, which considered five clinical variables that have been shown to be independently prognostic. So, at age over 65, the presence of blasts or circulating immature cells in the peripheral blood, anemia, hemoglobin less than 10, symptoms, fevers, night sweats, weight loss or a high white count over 25,000, you those points up.

And patients can do this online. There are calculators that you can calculate your DIPSS score. And, you’ll see that there are four different risk groups that range from low risk to high risk, and they are associated with median survivals. We now know that mutations influence those, have influence on prognosis. So, there are a group of high molecular risk mutations like ASXL1, SRSF2, IDH1/2. So, there are mutations that also have prognostic significance, and we incorporate them into the decision-making.

And, essentially, and this is where I think patients have to be very careful, physicians have to be very careful with conveying this. With these risk models whether they are clinical variable risk models or these integrated molecular risk models, each category is associated with a median survival, that’s based on retrospective studies. But that doesn’t tell the patient specifically what they should expect in terms of survival. And, I always fear that patients, when they look at these things, or even physicians when they convey them that they may inadvertently misrepresent or convey what those really mean.

And, I think the purpose of those risk stratifications is really to help guide a risk adapted treatment approach that’s reasonable and is weighted for benefit to risk of the disease. So, for example, if you have advanced disease with a high-risk score of intermediate to or higher, bone marrow transplant in certain patients may be a warranted therapy to consider. So, they really help inform treatment.

Katherine:

Blood and urine tests, bone marrow biopsy and imaging tests are all standard following a myeloma diagnosis, but what about more in-depth testing?

Because the terminology around biomarker testing varies, can you help break this down for patients, and how this in-depth testing is referred to in myeloma?

Donna:

So, biomarkers is a term that is commonly tossed around in many different cancer diagnoses and it means different things. But in general, it’s characteristics that can inform us about a diagnosis, about a patient’s prognosis and about their response to treatment. So, this can include things that we measure in the bloodwork, in the urine, even imaging. These are all things or markers that we look at to determine a patient’s either, like I said, response or risk stratification.

Katherine:

What about cytogenetics? What is that exactly and does that fit under the umbrella of biomarker testing?

Donna:

Yeah, so cytogenetics is a genetic snapshot of a patient’s cancer. So, it will give us a sense of how the disease will – the characteristics of how it will behave. But again, it’s just a snapshot and it’s not a precise science but certain mutations or certain genes will kind of inform us like “This might be maybe a more aggressive form and we need to do X, Y and Z.”

Katherine:

Which of these more in-depth tests are necessary in myeloma? Let’s start with the FISH test.

Donna:

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.

Katherine:

It seems that all of the test results can aid in determining outpatient’s risk. So, why is risk stratification so important?

Donna:

So, risk stratification is important.

It will give us a sense of how a patient might respond to certain treatments. Maybe a patient won’t respond as well to a stem cell transplant as someone with standard risk. So, we take this into account, but in this current time, in 2021, we don’t typically change our treatments according to risk. That’s why clinical research is very important because we’re studying right now patients with high-risk cytogenetics, do they do they better on certain therapies.

Katherine:

How do the results of these tests affect treatment choice and prognosis?

Donna:

So, someone who might have high-risk cytogenetics, we might want to be maybe more aggressive with our therapy. So, we might change how we want to maintain a patient. Usually, after a stem cell transplant, we give patients maintenance therapies. So, patients who have high-risk disease, we might change our strategy and have a more aggressive regimen in that maintenance setting. And with patients with higher risk, we probably will monitor them very, very closely in case – looking for signs for relapse.

Katherine:                  

What do the results of these tests tell us about prognosis and treatment choices?

Dr. Forsberg:             

So, the tests that we do are important in terms of understanding some degree how aggressive the myeloma may be or what the prognosis may be. One of the most common or challenging things to break through when diagnosing myeloma or learning about your myeloma is that it’s a little different than other types of cancer. Unlike other cancers that’re more common, stage in myeloma is very different than it is in breast cancer or lung cancer or things that people may have more experience with. In myeloma, everybody has systemic disease.

That’s a part of the diagnosis of myeloma. It means it’s a body-wide condition. So, being stage I or II or III is very different than what it might be in other diseases where that has a huge prognostic impact and also, really shapes what treatment might be. In myeloma, we do use blood tests and chromosomal changes to help us assign a stage to the myeloma, which may tell us about how aggressive the myeloma may be over time.

But our treatment approaches tend to be pretty similar, even for people regardless of their stage. So, our goals are always to get patients’ myeloma under control and maintain it there. So, treatment ends up overlapping pretty substantially. Regardless of what those in initial tests are that stratify potential disease aggressiveness. That being said, there are some ways that we do adjust treatment potentially in patients that we see evidence of potentially more aggressive disease or less. And that might be ways that we amplify treatment regiments, adding extra medicines or using maintenance approaches that’re a little more robust to try to help overcome those high-risk features.

Katherine:                  

What about the significance of chromosomal abnormalities?

Dr. Forsberg:             

So, chromosomal abnormalities are part of some of those staging systems. They’re included in what we call our revised international staging system, as well as just being part of our routine risk assessment.

To try to understand myeloma. So, in myeloma, at this point those genetic changes or chromosomal changes don’t necessarily drive specific treatment choices except in that they may stratify how aggressive disease could be and may be informative in that regard.

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.
