There are a few terms that often come up. No. 1 is “leukocytosis.” This often is a term that’s thrown around, especially in relation to myelofibrosis and also polycythemia vera, and this term means an elevated white blood cell count. That is a common thing that, as medical providers, we may just throw around in the room and not necessarily think about the fact that we should explain that a little bit better.

Additionally, “anemia” is a term very often used when talking about myelofibrosis, and that just means a decrease in red blood cells.

Often, people associate anemia with iron deficiency because this is probably the most common form of anemia, but as it relates to MPNs – and specifically, myelofibrosis – it is generally a problem with production that does not have anything to do with iron, but is actually more so just related to the disease and how the red blood cells are impaired because of the fibrosis of the bone marrow.

When considering treatment, remembering that clinical trials are an option – and often, a very good choice – is something that I really try to communicate to my patients. Generally, there’s a stigma around clinical trials as patients feeling like a lab rat or some sort of a study subject, and there is a perception that they’re not receiving as good of care as they would if they were not on a clinical trial. However, in my patients, I really try to dismiss this thinking because at this point in time, we do have really fairly good options for treatments with MPNs.

However, we do not have a cure for MPNs outside of a transplant, and our treatments are not perfect, and so, enrolling in a clinical trial really should be considered by patients and their providers as a very viable option.

It’s generally introducing perhaps a new way of approaching the disease treatment. Oftentimes, clinical trials are using a combination of agents, which is not necessarily available outside of the clinical trial.

And so, with clinical trials, we’re always trying to make something better. We’re trying to learn something, we’re trying to, No. 1, help the patient – so, my No. 1 goal in enrolling one of my patients in a clinical trial is to, first of all, help them, help control their disease, help them to feel better, and to live a long and good life. No. 2, we learn as we go along. Clinical trials are critical for drug development and for the future of treatment in patients with MPNs.

So, not only are our patients helping themselves, but hopefully, they are helping the future MPN patients who may come along and need a treatment. So, I always like to keep this really in the conversation when discussing treatments, and it may be up front, and it also may be after a treatment has stopped working that we consider a clinical trial.

So, there are also a lot of things that kind of go into clinical trial management and different requirements, so if a patient lives very far away, it may be challenging for them to come back to the academic center on a regular basis for routine clinical trial monitoring that’s required by the study, but if they live close by, I generally do recommend this. They are also associated with clinical research coordinators or clinical trial nurses.

And, these patients are monitored really very closely, and it’s kind of nice to have that extra person in it with you in the clinical trial, just another point person to discuss, perhaps, how you’re feeling or different questions or concerns as the clinical trial proceeds. So, when talking about treatments, in my opinion, especially in MPNs, clinical trials really should be one of the options that is first discussed when thinking about starting treatment, and especially if a treatment has stopped working.

So, there are very many exciting possibilities in MPN research right now. We have a lot of combination therapies, which I think I am most excited about, because we have a decent backbone of therapy at this point, but building on that and trying to maybe enhance the way that the backbone therapy works, and also to perhaps change the microenvironment of the bone marrow – basically, trying to reverse fibrosis.

So, there is currently a drug in clinical trial that is looking at this, and we are proceeding with this trial, and really hoping for the best, but I think that to combination therapies where we can put two things together that we think work really well together to help produce good outcomes – I think I’m most excited about that at this point.

When deciding about a treatment, it’s really important for the healthcare professional and the patient to discuss the patient’s goals.

The patient really is the key player here, and we as medical professionals are here to support the patient’s goals. So, what might work for one patient is not going to be necessarily the same treatment I would choose for a different patient. So, right off the bat, identifying the patient’s goals – and really, what are we trying to fix in one specific patient is going to look different from the next patient I see in that day.

For example, there are certain clinical manifestations of MPNs that need specific treatment approaches and maybe honing in on trying to help one clinical issue.

So, first of all, identifying the disease process – that’s No. 1. What is the diagnosis? No. 2: Coming up with a goals of care plan with the patient. What is causing them the most difficulty in their everyday life, and how are we going to fix that? That’s generally where I start.

Then, I discuss with the patients the different options for treatment, which either include therapies that are FDA-approved or enrolling in a clinical trial. And then, we really talk about pluses and minuses for each of these therapeutic decisions.

Patients may have different comorbidities, so they may suffer from different chronic diseases that may impact the treatment that is chosen with the patient and their provider, as well as discussing stem cell transplant, which we haven’t talked much about, but stem cell transplant is an option, and at this point, the only curative therapy for patients with myelofibrosis. And so, determining whether or not transplant is in the patient’s best interest is also a topic of discussion when deciding on therapy approach.

When somebody is diagnosed with an MPN, there are a variety of tests that are important for coming up with treatment strategies. And so, really, before starting treatment, it’s fairly imperative to have a CBC, or complete blood count, which was very likely done that led to the diagnosis of the MPN, but that’s very critical, as well as having a differential. This is basically just looking a little bit deeper at the white blood cells and their components, so that’s a critical part of the CBC, or complete blood count.

And then, having a chemistry panel, just to look at organ functioning, such as the kidney functioning and the liver functioning, as well as different electrolytes that may be indicative of something going on that would maybe impact treatment.

Additionally, having a bone marrow biopsy with molecular testing is advised. This is very critical in leading to the diagnosis of the MPN and then, also, really differentiating what subtype of MPN a patient may have.

The bone marrow is very critical for this purpose, and the genetic testing helps us to understand perhaps if a patient is having a higher-risk disease or a lower-risk disease and can help guide treatment as well. There are a variety of other chemistry tests that are done that can help specifically when looking at patients with polycythemia vera. This may be called an erythropoietin level.

Additionally, iron studies are generally recommended before starting treatment for MPNs, just to assess iron storage, availability, and that sort of component to the treatment may vary depending on that result. Additionally, if patients are having any sort of symptoms related to an enlarged spleen, generally, having an imaging study may be warranted if the symptom is quite severe and causing problems, and getting a baseline prior to starting treatment is generally a good idea.

When looking at a CBC, there are really three main cell lines that we monitor closely in MPNs regardless of the subtype, and this includes the white blood cell count, the red blood cell count or hemoglobin and hematocrit – those are measures of the total red blood cell count – and then, also, platelets. And so, these really are three different types of cells that your bone marrow produces that help with different functions.

And so, monitoring for any sort of changes within these three cell lines – white blood cells, red blood cells, or platelets – can really help us know maybe how the disease is changing, how a patient is responding to treatment, so these three key laboratory values are very necessary and really help us as providers and U.S. patients monitor progress, or for any changes in a positive way, or perhaps in a way that needs to be addressed.

When a patient is initially diagnosed with an MPN, seeking a second opinion is generally a very good idea, especially if patients are perhaps in an area where they do not have access to academic medical center.

The reason is that MPNs are such a small percentage of blood cancers – and, blood cancers in and of themselves are very rare, so MPNs are very rare, and especially in rural places, physicians do not have access or experience so much with MPNs. So, especially in those scenarios, I always advise a second opinion.

However, even within the academic medicine world, for example, if a patient is referred to me by their primary care physician or our institution, we always offer patients to seek a second opinion. Really, this is to gather information and either encourage the patient because the recommendation is the same or also to perhaps have a different idea for treatment that may fit the goals of the patient better, and so, I’m always telling patients to seek second opinions.

To overview the treatment types for MPNs, we have a variety of different mechanisms in which we use, and clumping these three main MPNs together, we can kind of break it down into, first of all, cytoreductive therapy, which is nonspecific, but really just reduces the amount of cells the bone marrow is producing. And so, it’s really to control the blood counts. And, different types of cytoreductive therapy generally are – hydroxyurea is used probably the most commonly.

There are some other sorts of chemotherapy that may be used in different instances. We also have biological agents, such as interferons, that may be used in patients with MPNs. We then have JAK inhibitors, which there are two FDA-approved JAK inhibitors at this point for myelofibrosis, and one approved for polycythemia vera.

We also have a variety of novel agents in clinical trials. These may be inhibiting different pathways of the cellular production or different signaling pathways at the level of the stem cell, so there are a variety of those. We also use hypomethylating agents in some patients who maybe have higher-risk disease, mainly myelofibrosis, that really changes the way that the stem cells are produced in the bone marrow in order to control the cell counts and also symptoms.

So, there are a variety of therapeutic measures that are taken. Additionally, not necessarily medication-related, but phlebotomy, which is considered a therapy for polycythemia vera, is generally used in order to reduce red blood cell volume, and then, aspirin is commonly used, especially in polycythemia vera and essential thrombocythemia as a supportive care medication to reduce risk of complications from the disease.
