Finding Your Voice #patientchat Highlights

Last week, we hosted an Empowered #patientchat on finding your voice and what stops patients from seeking a second opinion.

A second opinion is crucial to prevent misdiagnosis or unnecessary procedures or surgeries. A study done by Mayo Clinic showed that as many as 88% of patients who get a second opinion go home with a new or refined diagnosis. That shows that only 12% of patients receive confirmation that their original diagnosis was complete and correct. Still, a lot of patients never get second opinions. So, we wanted to chat about this and see what the Empowered #patientchat community had to say, and these were the main takeaways:

Finding the Funny When the Diagnosis Isn’t

It’s not easy hearing your name and [insert dread diagnosis here]. I know this only too well after having to find the funny in my own journey through cancer. Cancer is, however, most often a diagnosis that you fight to a defined end. What’s it like to find the funny in a chronic condition like multiple sclerosis, or HIV, or diabetes?

I have a number of friends dealing with the life-long aftermath of an MS diagnosis. One of them tipped me off to Jim Sweeney several years ago. Jim’s MS journey started with vision problems in 1985, he was officially diagnosed in 1990, and has been wrestling with the impact of that diagnosis – finding the funny most of the time – ever since. Jim’s body of work includes decades of live improv, and his one-man show “My MS & Me,” which you can hear on the BBC Radio 1 site. His MS has progressed to the point that he’s now in a wheelchair, and his public presence is mostly limited to Twitter, where his profile says he “can’t complain but sometimes do,” and YouTube.

Some other sterling examples of funny-or-die in managing chronic disease are Mark S. King’s fabulously funny My Fabulous Disease blog. Mark is HIV+, so he shares information, resources, and myth-busting about all things HIV in his posts and videos. He’s brutally honest about pretty much everything, with plenty of humor to soften the impact of what it’s really like to live with what anti-retroviral treatments have made a chronic illness, not the death sentence it too often was in the first two decades after the viral epidemic started in 1980.

Then there’s the “laugh out loud at the absurdity” Six Until Me site from Kerri Marrone Sparling, who writes about her life as a Type 1 diabetic. She covers everything from exceedingly random TSA security agent behavior when confronted with diabetes-related medical devices, to “pregnant while diabetic” to dealing with the emotional impact of living with a busted pancreas, all with a good dose of highly-readable snark.

How much courage does it take to laugh out loud, in public, at an incurable disease? Jim, and Mark, and Kerri certainly have courage – and comedy chops! – at the level required.

On the provider side, there are a number of docs who are breaking up the waiting rooms and wards.

The most visible of these comedic clinicians is Dr. Zubin Damania, a/k/a ZDoggMD  – “Slightly Funnier Than Placebo” was his tagline for years, before he shifted to “The Voice of Health 3.0.” ZDogg is a hospital medicine specialist who’s built an empire of snark over the last decade plus, some G-rated and some most definitely NSFW. His videos alone guarantee hours of laughter, and he’s one of the best users of Facebook Live around.

I’ve even found a scholarly article entitled The Use of Humor to Promote Patient Centered Care – be warned, though, that (1) it’s a “scholarly article,” meaning that it’s had all the laughs surgically removed and (2) they want $42.50 for it. You have been warned.

What’s my point here? I actually have two:

1. Laughter really is the best medicine.

Humor keeps us in touch with our humanity, and – unless it’s insult comedy, which I do not recommend in the health care arena, unless it’s insulting bad health care – it helps to comfort others in the same situation.

2. Patients and providers need to work together to help each other find the funny.

If you’re a doctor, don’t just say “you’ve got [insert dread diagnosis here], here’s the treatment plan, call if you have any questions, … NEXT!” Look your patients in the eye, and channel your inner comedian whenever it’s appropriate. If you’re a patient, connect with other people in your situation and see how they’re finding the funny. And help your doctors find their funny. If they can’t find it, you should find another doctor.

We all need to work together to break each other up. Laughter can comfort, can calm, it can even heal.

That’s real disruptive health care, no prescription required.

MPN specialist Dr. Joseph Scandura from Weill Cornell Medicine answers patients’ burning questions.


Transcript:

Andrew:
Greetings from southern California. I’m Andrew Schorr from Patient Power. Welcome to this Patient Empowerment Network program where you can ask an MPN expert your question. I’ve been living with an MPN, a myeloproliferative neoplasm myelofibrosis, since 2011. So, believe me, I have questions and I want answers just like you. I want to thank the Incyte Corporation for its financial support, but tell you, of course, that all the editorial control is our expert and our producers and me. Nobody tells us what to ask or what to say.

Okay, let’s meet today’s MPN expert. Joining us from New York City is Dr. Joseph Scandura. He is with Weill Cornell Medicine in New York City and he is also the scientific director of the Richard T. Silver Myeloproliferative Neoplasm Center at Weill Cornell Medicine. Dr. Scandura, welcome and welcome back to Patient Power. We’ve had you before. Thanks for being with us.

Dr. Scandura:
Thanks for having me, Andrew.

Andrew:
Okay, and I should mention that Dr. Scandura is a physician-scientist, so you can see that whiteboard behind him. He spends time in the lab, as well as seeing patients, in-patients, and in clinic. So, he is meeting us, but also working on a cure and we’re gonna talk more about that and hopefully, we can get there. Okay, are you ready for our first question Dr. Scandura?

Dr. Scandura:
All set.

Andrew:
Okay. So, this one comes from Philip who writes and he says, “I’m a 63-year-old male with PV, polycythemia vera. What does it mean that my blood is too thick?”

Dr. Scandura:
What it’s probably referring to, the term too thick is a little bit – can be generalized in a lot of different directions. It’s a colloquial term, not really a medical term, but what people often are referring to there in the context of polycythemia vera is too many red blood cells. If you think of the blood vessels in your body as being highways, they can only accommodate a certain amount of traffic. And you being in southern California are probably aware of this, that sometimes there’s too many people trying to get on the highway at the same time and that slows everything down. You could consider the highways too thick in that situation and that’s what’s really happening in polycythemia vera.

There’s too many red blood cells. There’s about 1,000 red blood cells for every of the white blood cells there, so the most common blood cell type and they occupy about half of the whole blood volume. And when you have too many being produced, they end up causing traffic jams in the blood vessels and that is what people are trying to describe when they’re saying the blood is too thick.

Andrew:
And you’re at risk for stroke and blood clots?

Dr. Scandura:
Yeah. So, it has a lot of both short-term and long-term consequences. Short-term certainly it provides a risk of having abnormal blood clots. That can be in an artery, so that could be a stroke, an artery in your brain, or an artery in your heart, a myocardial infarction or heart attack. It can also be a clot in a vein and so these, I’m sure you’ve seen them on TV, the advertisements for DVT or deep venous thrombosis or pulmonary embolism which is usually a clot in a vein that then has broken off and traveled through the circulation and landed in the lung where it can cause symptoms there. And so, the short-term risks of a clot are certainly elevated in people with polycythemia vera when the blood counts aren’t controlled.

Andrew:
Okay. Just one follow up question. Philip was wondering about this too. So, we see ads on TV whether it’s the DVT medicine ads or the blood thinner ads. Does that apply to people with PV?

Dr. Scandura:
It can. We treat people with PV to reduce the risk of a clot, but some people are diagnosed with a clot at the same time they’re diagnosed with PV and some people, even with the best of treatment, end up developing a clot. If it’s a clot in the vein, then one of the things that is a standard of care is to administer drugs that colloquially again are referred to as blood thinners. In this context, it has a different meaning and this is a group of drugs that interfere with the blood clotting system. So, these are proteins, not cells, and it’s what – if you ever have cut yourself and you feel just with your fingers, it gets a little sticky between the fingers. That’s actually clotting.

It’s a little bit like Jell-O. It starts out liquid and then it solidifies and that’s what your body does to help prevent bleeding. It forms this sort of polymer fiber that ends up being part of the plug. And what the blood thinning medications, the so-called blood thinning medications, do is they interfere with that process. Either given by injection or given by pill, the ultimate goal is to reduce the formation of that sort of sticky acellular clot. And that’s more of a treatment and can be a preventative for future clots as well, but it’s a little different than what we were talking about before in terms of too thick blood from too many red blood cells.

Andrew:
Too many cells versus the quality of the cells.

Dr. Scandura:
Yeah, but not even the cells. A lot of the blood clotting factors are produced by your liver. They’re not from the cells themselves that are floating around in the blood.

Andrew: I’ve never understood that before. So, thanks for explaining. I should also just say one thing about Philip. He shared with us that he has AFib. So, when somebody, and that’s not uncommon atrial fibrillation, does that complicate all the treatment for somebody with PV?

Dr. Scandura:
Well, one of the risks with AFib, some of them can be just related to the heart, it can disturb a little bit in how the heart functions and if people have some mild symptoms, AFib can make symptoms worse just from a heart function standpoint. But one of the things that’s related to, again some of the commercials you see on TV and the rationale for blood thinners, is the heart – the atrium, the left atrium which is really what fibrillates, which is just – normally the heart is pumping like this, all together coordinated. And what fibrillation means is it’s sort of not doing that. It’s going like this and what happens is the blood and the surface of the heart ends up not being pushed out normally.

And sometimes actually clots can form on the surface of that fibrillating heart and then when they get pushed out, they can travel. And because it’s usually the left atrium where this happens, when they travel they go into the arteries and then they can form clots and that can be stroke is the big thing people worry about. So, you can have atrial fibrillation that puts you at risk for stroke and that’s why people think about anti-coagulation medications to prevent that risk. And so, again, that’s another rationale for blood thinner, although it has nothing to do with the blood being too thick. It has to do with atrial fibrillation itself.

Andrew:
Okay. So, two things going on. Here’s a question we got in from Julie. Julie says, “What is the significance of a very low allele burden in a JAK2 positive patient?” And may you could define allele for us too.

Dr. Scandura:
Sure. So, as you know, we have some of our genes from mom and some of our genes from dad and the genes that we get are always in these two copies. And so, one copy from mom, one copy from dad, and they’re mixed and matched while we’re being sort of grown up from the embryo. But what happens in MPN is sometimes one of those copies, always starts with one of them, becomes mutated and that can be for instance, in the most common mutation, in the JAK2 gene, JAK2 V617F, a particular mutation that’s associated with abnormal function of the JAK2 gene product. And so, if we have just one copy in a cell, then one copy’s normal and one copy is mutant.

So, if we are talking about that one cell, that variant allele frequency, so that’s the abnormal gene. The proportion of all the genes that are abnormal would be 50%. Right? One abnormal, one normal. But now we think about all of the blood cells, trillions upon trillions of blood cells and then we have to take sort of an average of all of those cells. Some of them will be normal, some of them will be MPN cells, some of them will have one copy normal, one abnormal, some two abnormal, and some both normal. And so, when we look in a composite from a blood draw which is generally what people are sending, it’s a representation of how many abnormal alleles are present among all of the alleles of all of the DNA from the blood cells that’s been selected.

So, what a low variant allele frequency means that the proportion of mutant alleles in that sample of your blood is low. So, low would be maybe 10% or 5% or something like that and what is the significance of that? It’s an area a little bit of some debate, but there’s certainly a number of studies that have shown a correlation between the variant allele frequency in blood and the disease type itself. So, for instance, essential thrombocythemia, or ET, generally has a lower bearing allele frequency than myelofibrosis for the same mutation. And polycythemia vera is often in between.

Andrew:
While we’re talking about genes, I just wanted to bring in this question from Jocelyn because we’ve been learning are we JAK2 positive, are we CALR positive, these others that you’ve been discovering. So, Jocelyn said, “In 2006 I tested positive for JAK2 V617F. In 2018 I was told that I’m not JAK2V617F positive, but that I’m CALR positive. So, is it common for mutations to change and what does it mean?”

Dr. Scandura:
So, it’s not common for the mutations to change in terms of going away if they’re present, although there are certainly examples of this happening. It’s not common. What is probably a little bit more common is sometimes people have one mutation or a couple mutations and then sometimes more mutations are found later. And that often, not always, is linked to the disease changing its character itself. So, somebody with polycythemia vera having more of a fibrotic phase of the disease. In this situation, it’s a little hard to know exactly what happened, but there is a fair amount of variability from one laboratory or one test type to another in terms of sensitivity and the specificity of what is being detected.

So, JAK2 may have been at a very, very low level, could have been an erroneous measure, or it could have been at a relatively low level and the calreticulin mutation wasn’t tested for. And then later somebody retested with a different test that wasn’t sensitive enough to pick up the JAK2 mutation and they looked for a CALR and now that’s coming up positive.

So, the testing modality, the type of test that’s being done, and its individual sensitivity is an important part of this story and it’s a little hard, I think even for many physicians, to sort of get their heads around because it’s not like a blood count where you have international standards and basically a half-dozen equipment makers everybody uses across the world. There’s a lot of different technologies, each of which have little wrinkles to them that can limit somewhat exactly what’s being reported.

Andrew:
Okay. Here’s another one we got. This was actually asked by several people. Nick, Maggie, and Philip all want to know related to phlebotomy. What are the goals of phlebotomy as a treatment and how does it work and when do you know when it’s time to switch from phlebotomy to medication?

Dr. Scandura:
Right. So, I just came from a conference the end of the week and this is a topic of debate among physicians. When, whether to do phlebotomy? Whether phlebotomy therapy by itself is sufficient? What are the alternatives and when to make those decisions? I would say, I can tell you what my own feeling is. I feel that there is good support to justify that, but to be totally honest, there are physicians who feel differently than I do and I don’t know if any of us can claim to be absolutely correct. But I think we can all agree that the goal of phlebotomy in the short term is basically to take cars off the highway.

If you go back to the analogy of having too many cars on the highway causing thickened blood or this sludging from the red blood cells, this is a therapy specific to polycythemia vera, is that phlebotomy is just a very simple way of taking blood out of the system, taking cars off the highway. So, if you were to imagine and I frequently imagine this in New York City, is all of the sudden a third of the cars disappeared, it’d be a lot easier to get around. And so, that’s really what the goal of phlebotomy is, is to make it a little easier on your body to pump the blood around because there’s less resistance to having all that traffic in the vessels. How much? Go ahead, you had a question.

Andrew:
I was just gonna say, but debate about when to leave phlebotomy behind and have medication try to do the job when you prove one or others that may be coming.

Dr. Scandura:
So, I think the first goal is to get people under what would be considered control. So, an adequate level of traffic. And the numbers that are generally accepted by people in the field is having a hematocrit, that’s the portion of blood occupied by red blood cells, in males it’s below 45% and in females below 42%. Although we can all argue about that a little bit. I think people settle down around those numbers.

When is too much? My personal feeling and this is where there isn’t great data, so you’re left with opinion, but my personal feeling is it depends a little bit on the patient, the convenience, and I find that people who are getting phlebotomy more than four or five times a year, it ends up being a real burden on them in terms of the amount of time that they’re having, poor control of their polycythemia vera, and the amount of time required for phlebotomy, and the amount of risk of things like iron deficiency which can cause symptoms.

And then there’s some suggestion, I wouldn’t say great data, that maybe iron deficiency or repeated phlebotomy may be a risk in the long term, although I think that data is not very clear. My biggest determinant is patients, in my experience, just get a little fed up with getting phlebotomy when it gets above four, five, six times a year.

Andrew:
Okay. Thank you for that. I should mention to our audience again if you want to send in a question, whether we can use it on this program or a whole bunch we’ll be doing coming up, send it to mpn@patientpower.info. Okay, so here’s a question we got from Nick and all of us wonder about it. How often or do we need bone marrow biopsies so that you, as our doctor, and we are well informed about what’s going on?

Dr. Scandura:
So, another area where there isn’t – you know, in medicine we look for the perfect data. We’ve controlled – we treated one group of very similar patients one way, we’ve treated another group of people another way, and we compare and see who does better. What’s the better approach? This hasn’t been done for how often to check bone marrow. I think bone marrow evaluation is very important. Personally, I generally follow how the patient is doing as the primary determinant and if there are any signs that something is changing. And those signs can be how the patient is feeling, new symptoms that are arising, but oftentimes it can be just in how the blood counts are responding.

You’re on a stable dose of a medication for several years and all of a sudden it stops working or all of sudden it starts working too well. You have very low blood counts whereas before you were okay. That suggests to me something’s changing. The bone marrow is the factory for all the blood cells. So, if you wanna know what’s happening with the production in the factory you really have to look into the factory and see what’s going on. And so, that’s my personal threshold for doing a bone marrow, when I’m seeing something that’s suggesting that the factory is not functioning the way it was the last time I looked.

Andrew:
Okay. And for those of us who’ve had many bone marrow biopsies, and I have, hopefully where it’s done is someone who does it frequently. Usually, the anxiety we have is worse than the exam itself. It takes 15, 20 minutes, whatever and someday I’ll tell you the story of the lady down at MD Anderson who believed in voodoo and talked to the bone marrow as she was pulling it out. And it was so weird, that I was so distracted, I didn’t feel a thing, but anyway I understand it’s important.

Here’s a question that will help our friends with ET. This is from Michelle. She says – well actually now she has post-ET myelofibrosis. She says she has ASXL1 and TP53 gene mutations. Does the mere existence of these predict aggression and poor outcome? That’s what she worries about that those have been found.

Dr. Scandura:
Well, obviously every individual has their own history that they’re developing and so exactly what this means for you, for an individual, is different than what it would mean for a population of people with similar mutations. That’s really what we know in medicine. We look at people in a cross section and we say people who we can put into this bin tend to behave in that way, but within that bin, there are individuals who don’t act that way, the way that the others do. So, I would in myelofibrosis, in MDS, in polycythemia vera, P53 mutations are an area of some concern, as is ASXL1 mutations are also an area of some concern.

In ET it’s less well established and so I think because, if this was just ET and you had those mutations, I think many people, myself included, would say well, maybe we don’t know perfectly, but it is an area of some concern. I’m gonna keep a closer eye on you. Now that it has already evolved into myelofibrosis, I would say this is probably more like myelofibrosis where we know that P53 mutations, TP53 mutations, and ASXL1 mutations, can sometimes be some of the harder ones for us to treat. It’s something that, if an allogenic transplant is something that is possible, should at least be considered and discussed.

It doesn’t – speaking with a transplanter, getting typed doesn’t mean you have to get a transplant, but it gives you information and so I think that that would be a reasonable thing to do. Again, the decision at the end, it may not be the right decision for you, but it is something that is information for you to use in making informed decisions.

Andrew:
Right. I did have a consultation with Dr. Castro, who was at the time here in San Diego, exactly about that. Not to take action, but just to have the relationship and be typed, et cetera. Here’s a question we got from Paul. He says, “I was diagnosed in 2009. I take a weekly dose of 90 mg of interferon. How long can a patient continue to take interferon and what indicates a move to change treatment?”

Dr. Scandura:
So, we have people who have been treated for 20 plus years with interferon. So, I don’t know if there is a known duration which is too much. For many patients it’s a very well tolerated therapy, can be quite effective, and I think that it is one of the few medications that seems to have some disease-modifying activity. However, when to change? If it looks like it’s not working, it’s time to think about changing and that can be adjusting the dose, but I think if somebody has been on it for a long while, that’s when I think thinking about additional therapy, either adding another medication to the interferon or changing completely to a different medication.

Clinical trials, there’s a lot of activity in MPNs in clinical trials. Thankfully, over the past five years or so, it’s really been increasing. There’s a lot of options. There’s some drugs that we’re really pretty excited about right now in terms of thinking they might have some nice activity and talking to somebody about what might be a suitable treatment for you if the interferon was not working anymore.

Andrew:
Okay. Here’s a – again we’re getting similar questions from a number of people. So, Ragita, Nankin, Raven if I’m saying the name right, and Jacquelin sent in basically this question. How common is it in patients with MPNs to have bone pain? What causes it? Is there anything that can help with the pain?

Dr. Scandura:
So, bone pain is always on the list of symptoms reported by patients with myeloproliferative neoplasms. I wouldn’t say, in my experience, it’s one of the more common ones. It might be a little bit more common early in disease. Sometimes things like phlebotomy that you can actually have a rebound where the bone marrow is a little bit revved up to try to replace all those cells that were taken out, that can cause some bone pain. It can be seen in myelofibrosis occasionally and sometimes when the disease is becoming more aggressive or is having a – changing its pace. But the cause of bone pain, we think of as being related to sort of expansile pain.

So, the bone marrow, the factory for all the blood cells, sometimes is just working so hard that it causes, it irritates the bone fibers that are around the surface of the bone. There’s very little in the way of pain fibers inside the bone, but on the surface of the bone you have a lot and that expansile pain, that gives that sort of vague, achiness people often describe as bone pain. The treatment for bone pain in some ways is determined by what the cause is. If it’s just, for instance, a rebound after phlebotomy, it can last a day or two and then go away. And so, short-term symptomatic treatment with non-steroidal anti-inflammatories, NSAIDs like Motrin, can be helpful or Tylenol even.

But occasionally patients report a real benefit from things like histamine blockers which the mechanism for that is entirely unknown, but there’s certainly a population of patients who feel like the bone pain has gone away with medications like Claritin you can get over the counter. It’s worth a try. They are very well tolerated medications and not all patients have any symptomatic benefit, but a subset of people do. If the bone pain is related to the cells being too active, a very proliferative feature of the disease, sometimes it dictates treatment.

So, if you were on phlebotomy alone, well maybe it’s time to change to a more cytoreductive therapy and see if that can help with the pain. Sometimes it prompts additional evaluation. If you’ve never had bone pain, all of a sudden the blood counts are a little different, you have bone pain, it might be something somebody would think about doing a bone marrow evaluation for. Again, looking in the factory which is probably where the cause is coming from.

Andrew:
I have a couple more topics I want to cover just before we close. We’ll go just a little bit longer if that’s okay. So, Robert wrote in and said, “How does a stem cell transplant cure myelofibrosis?”

Dr. Scandura:
So, I’ll go back to that factory analogy. If you think of the bone marrow as being sort of corrupted by these MPN cells. You have, normally this is a very orderly factory. It’s producing a number of different lines if you think of it as a car factory. You can be producing red blood cells maybe your sports cars, and your white blood cells, your infection-fighting cells, as sedans, and platelets as SUVs, but it’s all very orderly and it should be proceeding in a regular way. And you get MPNs and somebody has just turned up the volume and are just cranking out a lot of cells. And sometimes that production starts becoming abnormal too and that’s more like in a myelofibrotic setting.

And so, what is the point of a stem cell transplant is really to clear out that factory, get rid of all the workers in there, and replace them with completely different workers to come in, set up shop, clean up the factory, and start normal blood cell production. There’s another part of it is, it’s not just the blood cells, it’s actually the immune system. And so, you’re giving the recipient an entirely new immune system. You have to wipe out the old immune system to allow the new donor cells to get a hold in the bone marrow and then they have to be educated to sort of relearn how to fight off infections and to figure out who is who.
So, graft versus host is one of the complications where those cells from another person come into the recipient and say, “Ah, I don’t know you. I’m going to attack.” And so, that can be a problem. It can be a short-term problem. It can be a long-term problem. It can be mild and it can be severe, but there’s another edge of that sword which is what we think of as graft versus leukemia effect, or in this case it would be graft versus MPN effect where some of those donor cells recognize the little differences between them and the MPN cells and wipe them out. And so, that’s really what you’re trying to do is allow that new immune system to find the bad actors and wipe them out.

Andrew:
Okay. You touched on something I think we’ve got to ask about and that is people are hearing in the blood cancers now the experimental and in some cases an approved approach called CAR-T, chimeric antigen receptor T-cell therapy, but again immunotherapy to train the T-cells to fight your ailment. What do you think about that in MPNs? Does it have promise?

Dr. Scandura:
I mean, it definitely has promise. It’s been a challenge in myeloid disease as a whole, so AML, MDS, MPNs have not been the first diseases where this has been shown to be successful, more lymphomas where it has had a lot of traction and some nice responses. What it really is it’s a living drug and this can be done in a couple different ways. They can be cells from yourself that then are treated in the laboratory so that they start recognizing these immune cells. You start tricking them into saying, “I’m going to attack this particular thing.” Even though they weren’t really trained to do that, they are now being tricked into doing that.

And so, in a disease like a B-cell lymphoma, most of them express a particular protein that’s on B-cells, CD19. So, if you take these CAR-T cells and you say, “Well, go out and kill everything you see that has CD19 on it”, it will wipe out a lot of those lymphoma cells. In myeloid diseases like MPNs, it’s a little harder. The targets are not so clear-cut and they’re shared with normal cells. There’s one area where I think it has the most promise is calreticulin because the mutation in calreticulin isn’t a tiny little mutation. It’s a mutation that causes a whole new end of the protein that doesn’t exist in the body otherwise.

And some of the calreticulin actually gets onto the surface of the cells so it’s displayed to the immune system, and so this is an area where I think there’s some promise for CAR-T cells to target those calreticulin mutant cells. There may be other targets as well and I think we’ll learn as time goes along. People are trying to target molecule CD123 which is expressed on certain abnormal stem cells. The problem is it’s expressed at relatively low levels on those cells. It’s also expressed on normal cells and it’s expressed at higher levels on much more common cells. So, it makes it a somewhat imperfect target, and also difficult from a drug standpoint because there’s a lot of people wearing the same mask, only some of them you want to kill. So, it can be a problem.

Andrew:
Okay. You have quite the analogies. But, I’m just gonna ask you about two more questions and then we’re gonna have to go. This came in from Linda who says, “I am CALR positive and I have many symptoms. What causes vision symptoms for me and migraines? Can that be tracked to the CALR somehow?”

Dr. Scandura:
It’s common in a subset of people with MPNs. Sometimes it’s linked to the platelets themselves, to the white blood cell count, so I would certainly unless there’s a reason not to try aspirin, that’s something that can help with patients. It may also be an indication for cytoreductive therapy, so actually trying to lower the blood counts. I don’t know exactly what disease that Linda has, but it’s one that I would think is a symptom that would warrant therapy because it can be quite bothersome.

The vision changes is something that may be related to the migraines, but it’s also something that might prompt a visit to an ophthalmologist so they can actually look at the blood vessels in the back of the eye and sometimes what happens is you can have a little irritation of the blood vessels or even clots in those blood vessels and that’s something that would definitely trigger a change or new therapy.

Andrew:
Dr. Scandura, our audience is saying, “Please, one more question, one more question.” So, if I can a couple more. Philip said, “Is iron deficiency a new normal if you have PV and you’ll, therefore, have weakness, fatigue, maybe even some cognitive issues because of anemia as well?”

Dr. Scandura:
Yeah, so I sort of fall in the camp, as I mentioned before, there’s some debate in the field and I sort of fall in the camp that if you’re getting symptoms from iron deficiency, it might suggest that something other that phlebotomy could be beneficial or could relieve that symptom. Everybody, if you take enough blood out of them, is going to become iron deficient and, in fact, most people diagnosed with polycythemia vera, if tested, actually meet the criteria for iron deficiency, not because they actually don’t have enough iron in their body, but because all of the available iron is soaked up in making red blood cells. Red blood cells are red because of iron.

So, if you think about all of the iron in your body and all of the places it’s used for metabolism and everything else, there’s a lot of enzymes that actually use iron as part of their catalytic site. A large proportion of all of the iron in our body goes to making red blood cells. In polycythemia vera, that regulation is completely abnormal and you end up just making a lot of red blood cells that aren’t needed and it soaks up all the iron. Then when you start doing phlebotomy, you’re taking all of that extra iron and you’re taking it out, but the bone marrow still wants to try to make red blood cells. So, it continues to scavenge as much of the iron as it can.

So, iron deficiency is pretty common and if you need a lot of phlebotomies it’s universal. Some patients, in my experience, meet all the criteria for severe iron deficiency have very little in the way of symptoms. Others meet criteria for mild iron deficiency, but they’re quite symptomatic. And so, in those instances, you need to individualize a little bit. At least give a try to a different therapy and allow the iron stores to normalize and see if that improves the symptoms.

Andrew:
Okay. You used the word individualize and that’s where I wanted to wrap up. So, you alluded to earlier, that you were encouraged by new medicines coming for MPNs and you have your whiteboard behind you where you’re charting things and I hope, Joe, coming up with a cure of tomorrow for all of us. How encouraged are you in the near term and the longer term for beating back or even curing these diseases?

Dr. Scandura:
I think we’re gonna cure these diseases, I do. I don’t know if it’s gonna be this year, but I think that the number of tools we have to understand how these diseases work and the number of new drugs that are being developed that have real promise, like real mechanistic reasons why they should work, I think is going to yield, reap rewards over time. People have heard this for a long time. The war on cancer has been going on for a long time, but I think we didn’t have the tools that we have now for that entire duration. Right now, we can sequence a genome in a week of a person. Now, do you need to do that? No, but it allows you to get a level of information that was in the past, really just fantasy world, science fiction, and now it can be done on a routine basis.
There are, virtually all of our patients, have sequencing for 40 plus genes. It allows us to know a little bit more about what their risks are, and also gives us a spectrum of targets to start hitting. There’s models that are better than what we’ve had in the past for many of the cancers that have been targeted. Breast cancer models, you know, there’s some decent breast cancer models, but they’re very complex tumors. MPNs, for better or for worse, if you look at the spectrum of genetic complexity, they’re really pretty simple meaning that they have one to half a dozen mutations.

Now mutations aren’t the whole story, but it’s a good starting point and if you only have maybe 10, 15 genes that are currently mutated in a disease, it’s trackable. You can figure this out. You can figure out what they’re doing to allow them to win and once you know that, you start figuring out how to beat them back. And so, I think that their time is gonna come. I don’t know if it’s this year as I said, but I think it’s definitely doable.

You know, CML, when I was a kid, when I was in medical school my parents had a good friend with CML who died with CML. Now, it just wouldn’t have happened. He would have been fine, but he was on, for a long time, ineffective therapy, transformed to an acute leukemia as they all did, and then it becomes really untreatable. And now we have these magical drugs, semi-magical drugs, that for the vast majority of people just – it’s a pill a day. It’s amazing.

Andrew:
Well, you’ve got that work on your whiteboard and in the lab and your colleagues around the world and you had told me before the program started that you all are collaborating better now than ever before. So, Dr. Joseph Scandura from Weill Cornell in New York City, thanks for what you do as a physician-scientist and thanks for spending time with us today.

Dr. Scandura:
It was my pleasure and thanks for helping patients through what is a difficult ordeal I think in terms of adjusting to a diagnosis and getting information.

Andrew:
Well, thank you for joining us and Weill Cornell folks have been great and send our best to Dr. Silver too. He’s in his 90s and still going strong.

Dr. Scandura:
Yeah, he’s traveling today.

Andrew:
Thank you so much for being with us for this Patient Empower Network program. Thanks to Incyte for helping fund our series. We appreciate their commitment to the MPN community and as always, I just sign off by saying I’m Andrew Schorr and remember, knowledge can be the best medicine of all.

Ask the MPN Expert – Dr. Pemmaraju

“Ask the Expert” session with MPN specialist Dr. Naveen Pemmaraju from The University of Texas MD Anderson Cancer Center.


Transcript:

Andrew: And greetings from near San Diego, Carlsbad, California. I’m Andrew Schorr from Patient Power. Welcome to this patient empowerment network program, and thanks to Incyte Corporation for helping make it possible. They have no editorial control. I’m a myelofibrosis patient, have been for several years, so I’m vitally interested in this. Welcome to our MPN community, and welcome to one of our favorite experts joining us from MD Anderson Cancer Center in Houston. There’s Dr. Naveen Pemmaraju. You can see behind his desk there all the working on the cures of tomorrow, but Naveen, thank you so much for being with us.

Dr. Pemmaraju: Thanks for having me, Andrew. My pleasure.

Andrew: Okay. Let’s get right started. We’ve gotten all sorts of questions in. If you have a question, send it to MPN@patientpower.info, but we’ve gotten a lot already and I’ll start to buzz through them over the next 30 minutes. This question is from Cynthia and she says, “I was diagnosed with ET (Essential Thrombocythemia). I’m JAK2 positive,” so she has that JAK gene. “When I was 66 years old,” now she’s 68, I’m about to be 68 as well, “What markers on my blood work, asides platelets, are important for my doctor to watch? What indicates a need for another bone marrow biopsy?”

Dr. Pemmaraju: Well, thanks, Andrew. And thanks to the question from Cynthia out there. This is very important. This is what we talk about day-to-day, week-to-week in the clinic. There are a couple of perimeters outside of the platelets. One, I would say the most important for us to watch are the other of the big two. That’s your hemoglobin number, also known as anemia; if it’s too low, or polycythemia, if it’s too high, and then the white blood cell count is also very important. Again, if too high, or too low, it can tell us what’s going on.

With ET, the key thing is it can transform, or change into any of the other MPNs. For example, PV (polycythemia Vera), myelofibrosis, or – and I hate to mention it, but it does happen five, maybe seven percent of our patients, where the disease can go to Acute Myeloid Leukemia, AML. So, distinct blood count changes, either too high, or too low, can give us clues if the MPN is changing, or in fact, going to AML.

And so, the answer for a repeat bone marrow is based on that, which is, let’s look together, patient and provider to see if there are subtle or avert changes in the blood counts that are markedly different from the previous visit, rather than having a pre-prescribed, every three months, or every six months type of a deal.
Andrew: But, Naveen, with all you’re doing now with sophisticated testing, do you still have to poke us in the hip, or couldn’t they just do it from our arm?

Dr. Pemmaraju: I wish, Andrew. I think this is very important. I think with the juxtaposition, you have this sophisticated gene panel testing, JAK2 CALR, MPL, and yet we’re still sticking a needle in people’s backs in a very painful procedure. Nothing still has overmatched as the gold standard, the bone marrow aspiration biopsy. So, for now, we’re – pun intended, I guess – stuck with this procedure. But your point is a good one. For example, with bone marrow transplant, can you believe it nowadays, they’ve moved from not having to exclusively do it from bone marrow source to peripheral blood, so I think you’re on the right track and we need to work on different ways of accessing this important information.

Andrew: Okay. One thing about bone marrow biopsy, it doesn’t have to be painful. It’s uncomfortable, but it doesn’t have to be painful if you have somebody experienced doing it.

Dr. Pemmaraju: I wanna emphasize how right that is because at least here, at our center at MD Anderson, as you know, we have a team that is dedicated to doing it many, many people, many repetitions doing it, so there might be local discomfort, but a lot of our patients do not experience pain. I’m glad you brought that up.

Andrew: Right. And that’s been my experience both there, and at other major centers. Okay. Here’s a question from Denise. Denise says, “I have PV and I’m trying to improve my health by making smoothies containing large amounts of dark green vegetables, such as spinach, kale, and watercress. I’ve been warned by some members of our community that these foods will increase iron and raise the hematocrit, putting me at risk. Is that true? And should people with PV avoid these foods that are high in vitamin K?”

Dr. Pemmaraju: Well, this is an important question and I remember five to 10 years ago we would say things like, “Well, we don’t really know the answer,” or you know, “Diet doesn’t really have anything to do.” But now with more and more understanding of the total therapy for patients and approach to the whole body, I think this is an important question. So, yes, iron levels do matter. Too low, then you’re iron deficient. (That can definitely happen in our patients.) Too high, potentially may fuel the fire, if you will, for polycythemia Vera.

So, I think iron levels are important to watch and certainly can be increased by what our question is being asked about. But there’s another aspect, too, that some of the medications that we prescribe and take. One example is Coumadin, or Warfarin that a lot of our patients know, which is a high-level blood thinner. It’s an anticoagulant. And man, oh, man, that is exquisitely dependent on the vitamin K pathway. So sensitive, that in some patients in some cases even salad consumption, or spinach, so healthy foods because of the vitamin K level in them can alter this level. It’s called the INR. And so, it’s something we have to watch out for.

So, not only in terms of iron metabolites, but also drug-to-drug interactions. So, it is always best to mention these things when we’re going on new medications.

Andrew: Right. Talk to your doctor.

Dr. Pemmaraju: Talk to your doctor.

Andrew: What you’re doing –

Dr. Pemmaraju: Everything.

Andrew: – what you’re eating. Yeah. Okay. Here’s a question from Sally. Sally says, “I have ET with the MPL mutation. So, I have JAK, but there’s also MPL. I believe, not much is know about my mutation. Can you shed light on it, or me and our community here today?”

Dr. Pemmaraju: Yeah, great question. So, when I look at these mutations as the big three, I go back to the time of William Dameshek, who hypothesized in the ‘50s and ‘60s that MPNs would be a unified group of diseases; ET, PV, and MF. And now, 67 years later, we’ve proven that. So, JAK2, we’ve known about since 2005. The most common, most major recurring mutation, fifty to 60 percent of patients of myelofibrosis. Then in 2013, 2014 the CALR mutation was elucidated. Can you believe, that’s only been four, five years. That’s the second most common. But there’s a third of the big three. That’s the least common, the MPL; MPL mutation.

That’s a mutation in something called the thrombopoietin receptor (TPO), which is in charge of helping to stimulate and make platelets. So, in terms of MPN patients, it does make sense and it has something to do with platelets, and that axis. It is the least common; by far the less common of these three, so I would say maybe something to the point of three to seven percent of our patients will have it.
Up until recently, we didn’t know if it had any prognostic significance, but our Italian colleagues published a very nice paper in Blood a few years ago, independent of the IPSS risk, that I’m sure we’ll talk about later. That if you just take patients with myelofibrosis, not ET and PV, you can stratify our patients based on the mutation risk. And not everyone knows about this.

For example, in this scoring, CALR mutation alone is the best prognosis for our patients. JAK2, or MPL is what’s called an intermediate prognosis, and the so-called triple negative, if you don’t have any of these big three, the implication being that you likely have something else, like ASXL1, then those patients tend to have the worst prognosis. So, MPL helps us to diagnose and confirm an MF diagnosis, and it also may have prognostic significance in our modern era.

Andrew: Okay. I don’t want people to freak out because this is a moving target as they learn and say, “Oh, my god. I have triple negative…

Dr. Pemmaraju: That’s right.

Andrew: Right. Okay? Because there’s progress going on all the time.

Dr. Pemmaraju: Well said.

Andrew: This is what they’re learning now. Okay. Now. Here’s the big one and you mentioned it. You said, a small percentage of us with myelofibrosis have the risk of progressing to AML. I know there been a lot of new drugs now either approved, or in development for AML. And some that help people who have secondary AML.

Dr. Pemmaraju: Oh, yes.

Andrew: Right? But tell us about the risk of progression, and then what do you do about it?

Dr. Pemmaraju: Right. So, that’s a great topic, and as you know, you’ve been doing this for so long now. This has often been a very not great part of the conversation, but it’s an exciting time for our patients based on the research I’m about to share. So, the first part is progression to AML, which we touched on earlier. We do have an objective prognostics scoring system. Actually we have so many scoring systems now that many of our patients are starting to see them.

But the IPSS, or International Prognostics Scoring System, was first developed by our colleague, Cervantes et al, this is right before 2010, so ’07 to ’09. That one is supposed to be applied at diagnosis and based on five of these risk factors, we can prognosticate, or tell which of our patients are at a higher risk for AML. And so, a lot of our viewers ask that. So, it is true. Age – over a certain age, white count of 25,000, circulating blasts, constitutional symptoms, and anemia made up that original five.

Since that time, there are dynamic scoring systems, DIPSS, DIPSS+ and others that include, or modify as some of those risk factors. So, we can tell, at least based on a textbook impression, who has a higher likelihood of going to AML. Once our patients go to AML, there’s a lot of hope now. There have been four – count them – four new FDA approvals for AML in just the last 12-24 months. They apply to different segments of AMLs, two of them are targeted therapy, so one drug called Midostaurin hits the FLT3 inhibitor, one drug hits the IDH1 and 2. Actually those are two separate drugs.

The drug you were referring to had a code name CPX-351, or VYXEOS, and it does have an approved label for so-called secondary, or therapy-related AML. Although I will caution our viewers that – MPN patients, specifically, we’re not included in those early data sets. They were more geared towards patients with MDS leading to AML, but the principle is there for us.

And then finally there’s another drug called Gemtuzumab or Mylotarg. So, you have four FDA approvals, ongoing clinical trials with combination therapy, excitement and ongoing investigation for CAR-T cells, optimizing stem cell transplant, and then combining possibly MPN drugs with AML drugs in a clinical trial setting. So, I think this is actually a very, very important time to talk about AML in all of our MF and MPN sessions.

Andrew: Okay. Just one brief question, and – if someone like me, where I’m on Jakafi myself, but if that sort of poops out, or that, or another medicine is not working for me, and I’m developing AML, do you feel now it’s a more hopeful time than it’d had been previously?

Dr. Pemmaraju: I do, Andrew, and you know me. I used the word ‘hope’ very seriously and very carefully. Before with AML – and I mean, just five to seven years ago, it was not as hopeful of a time for us, as researchers, and for our patients. Not just because of the FDA approvals. That obviously is very encouraging and applies to a lot of our patients, but also because of the funding, the research, and the ideas for combination chemotherapies, and the emergence of these immune therapies. I think it’s a hopeful time for all of us involved with AML.

And specifically as you were mentioning this secondary, or post-MPN, or post-MDS AML, which is largely been an urgent unmet medical need.

Andrew: Okay. And just to everybody understands, AML, Acute Myeloid Leukemia, so it’s acute and as has been in the past a five alarm fire and now they’re developing medicines for that. All right. Let’s go on. Bonnie has a question. “I have myelofibrosis and my only symptom is that my spleen is enlarged. I’m on Hydroxyurea, but hesitant to switch to Jakafi or Ruxolitinib. Assuming no real discomfort and just moderate weight loss and stable blood counts, does an enlarging spleen itself cause problems?” And also, I guess the bigger question, Naveen is, is there a penalty for waiting if there is a treatment that might line up with what you got?

Dr. Pemmaraju: You’re right on. Yeah. This is very, very serious, important topic. So, for the first part of the question, the spleen itself being enlarged can in fact cause some really, really big problems for a lot of our patients. It is true, as the questioner’s asking, that one can have mild splenomegaly. So, a spleen that’s slightly enlarged, not yet causing physical symptoms of early satiety, which means getting full fast, or physical discomfort, but a lot of patients do have that. So, yes, a big spleen alone can cause not only local problems, but also systemic. Because again, it’s a disease of cytokines; messengers and proteins that are being scattered all throughout the body, causing the body to feel flu-like symptoms, or fatigue.

Now, the studies for Ruxolitinib are very specific. These are two Phase 3 studies, they are called Comfort 1 and 2, published in the New England Journal five six years ago now. And they did include patients with intermediate to, or high-risk disease. Or intermediate to high-risk disease, shall we say. And although the spleen itself doesn’t come out in the scoring system, some position is that it should be patients with more advanced, or higher scoring diseases than say someone with lower risk disease.

So, with the trial data that we have we know a couple of things. 1) The drug got approved in those more advanced patients. 2) There was early crossover that was allowed. So, one of the comfort studies, Andrew, was as you know, randomize to placebo. So, no active therapy, and one was best available therapy. Even with the early crossover allowed to the Ruxolitinib, both are not showing overall survival benefit. Translated into more layman’s terms, what that means is, it does appear, maybe, possibly, that if you got the drug at the beginning early on, there looks to have been some long-term benefit.

We won’t know that until further studies are done, and those studies are being planned. Those are called ‘early intervention’ studies, so people at a lower, earlier stage, low risk, Intermediate 1, and I think we’ll all be eager to see how that benefits our patients.

Andrew: Okay. Great. So, the penalty for waiting – right now it appears there could be a penalty. In other words, it could be better to get on it. Don’t wait. If you and your doctor agree, there’s a therapy for you.

Dr. Pemmaraju: I think that’s exactly the resource position to take, which is I think that – I believe that there are a subset of our patients who exactly fit what you said. They are symptomatic, out of proportion to the risk scores that are available. The spleen is highly enlarged, although they have lower intermediate risk by IPSS. And that’s exactly the are of investigation for myself, and our colleagues. And even in the clinic there might be some role to assessing patients as you said like that. So, it shows you the limitation of these text book scoring systems and how much research we have left to do.

Andrew: Okay. Well, you know more than you did before, so, I –

Dr. Pemmaraju: Well said.

Andrew: – I’m happy about that. Okay. So, here’s a question from Jane. She says, “I have myelofibrosis, but it’s not progressing, and I’m CALR negative.” So, that’s one. “I’m JAK negative.” That’s two. “And I’m waiting to hear if I’m actually triple negative, as you said, which would be JAK, CALR, and MPL. Are there medicines to slow progression for me?”

Dr. Pemmaraju: Well, that’s the ultimate question. Isn’t it? So, the first concept is this triple negative. And if our viewers have heard that before you have, that was borrowed from the breast cancer literature, which was a similar sentiment, which is having the top three markers negative. And just in that case, as in RMF, the supposition is the same, that that means that you have a higher risk disease.

But going from negative to positive, what it does mean now with the new sequencing and molecular studies that are coming out, is that it really looks like 90 percent, maybe even close to a 100 percent of patients, have some form of a molecular driver. And those other mutations you’re going to start to hear about are becoming common; ASXL1, TP53, EZH2, IDH, etc. etc. So, triple negative may mean that we don’t have those big three, but there might be something else that’s driving the MF, and it means that it’s a higher risk to progress to AML and for some patients to not do as well.

But this questioner brings up a very good point. What the textbook risk score says does not have to imply to each individual patients. So, just because the finding is that, okay. Triple negative patients as a population may do worse, it may not apply to that individual patient. So, in this person’s case, maybe they’ve been diagnosed very, very early. That’s a good thing. Maybe the driver mutations and the triple negative matter, which is what I think. So, ASXL1 mutation vs. some other ones.

And then finally, each patient is different. Everyone’s case is different. You have other co-morbidities, other underlying drivers of disease. So, I think that’s the good point. But, we do have to say, at least for right now, I like your phrase ‘of a moving target’. The understanding that if you are this triple negative disease in this classical sense, should mean that you are a higher risk at some point to progress, as compared to others in your group, and so, possibly closer monitoring and observation is necessary.

Andrew: Right. And see an MPN specialist. Because what if there’s a drug in development that’s an AS – What is it? AS –

Dr. Pemmaraju: ASXL1.

Andrew: Inhibitor. And that’s driving your bus. Right? Maybe you wanna be in that trial. [

Dr. Pemmaraju: Absolutely right. Clinical trials are important for all of our patients with any rare cancers, or any cancers in general.

Andrew: Right. Okay. Let’s go on. I just wanna take this question from Susan. It really rang true for me. Susan writes, “Is it common for an ET patient to experience numbness in the scalp, ears, and face? I’m currently on 1,500 milligrams of Hydrea daily.” And I wonder if you can broad this out because I was telling you before the program, I’m getting every once in a while – I wake up with a little prickliness. Not itchy, and I go back to sleep, but is that related to my MPN? So, she has scalp questions, is it the MPN, ET whatever? Is it the medicine?

Andrew: This is coming up in my clinic on a weekly basis. The short answer is, yes. It’s always due to the MPN. And I’m here to tell you why. This is an underappreciated part of what we do as healthcare providers in patients. For anyone who’s ever filled out the Myeloproliferative Neoplasm (MPN) Symptom Assessment Form Total Symptom Score:, developed by Ruben Mesa, his colleagues, now shortened down to a nice, nifty 10 ques – sheet. You know, actually, peripheral neuropathy is one of those 10 questions. Do you have numbness and tingling? So, even though we don’t talk about it, that’s our fault, peripheral neuropathy is a thing. It’s a common aspect of the MPN.

No. 2 is – and you brought this up to me nicely as well, is some of the mediations that we prescribe at the chemotherapeutic level can also cause nerve damage and neuropathy. JAK inhibitors either as a class, or some of these individual ones, both FDA approved in clinical trials have been associated with either a central, or peripheral neuropathy. So, I think that’s another big aspect.

And then finally, I hate to say it, but these drug-to-drug interactions of all of these medicines can cause that. When you factor that, plus vitamin deficiencies, thyroid deficiencies, iron abnormalities, restless leg syndrome, our patients have a host of reasons to have neuropathy. Usually this is an intermittent phenomenon, a come and go phenomenon. When it starts to become more of a permanent phenomenon and progressive, that’s a big concern, and that would really require a separate neurologic work up.

True, there are some chemotherapy drugs that can cause that, but I would say that would necessitate a multi-disciplinary approach; neurologists and all of this kind of thing.

Andrew: Okay. You used the name of a drug that people take. Is a blood thinner, Coumadin. Somebody may take diabetes medicines, I also have Chronic Lymphocytic Leukemia and take medicines for that. Okay. So, if we’re developing some of this and we have an MPN, which of the many doctors we have doo we go to first – do we go to you as our MPN specialist? Do we start there?

Dr. Pemmaraju: Yes. Absolutely. I think the phrase and the motto of every MPN expert that you’ll meet (and you and I know all of them now) is, ‘Tell us everything.’ Because I will tell you what. Now that we have more understanding – not full understanding yet, but more understanding of the biology of these diseases, it turns out that a lot of things that are happening are due to MPN.

One example I’ll give you, Andrew, our colleague and friend, Claire Harrison has pioneered this phrase called, ‘presenteeism’. Presenteeism. Not absenteeism, as we learned when we were younger. The concept that our patients with MPN are there, they’re here at work, with their loved ones, they’re at dinner, but they’re not really there. That’s also a question on the questionnaire; inability to concentrate. Subtle, subtle, subtle, but this is part of the MPN process. We’re not talking about it enough, but programs like this will get the message out there. So, tell your MPN doctor everything because more than likely they know it’s part of the MPN.

Andrew: I gotta tell my wife. I’ve been married 33 years.

Dr. Pemmaraju: This is all recorded, so you can tell her.

Andrew: All right. Esther, where are you? Okay. No. Let’s go on. So, Heather sent in this question. “My local hematologist, oncologist will only give me a phlebotomy after my hematocrit is over 51. What is the standard marker? I have PV and I’m really struggling with symptoms.”

Dr. Pemmaraju: I actually have data to share with you and your viewers. So, before four years ago, we did use to do it either based on convention, symptom burden, or a pre-designed abstract number. But now we have data. So, our Italian colleagues, Barbui and colleagues published in the New England Journal about four years ago a very nice paper that starts to answer this question. They randomize patients with P. Vera to two groups. They called it a liberal group, where you could get phlebotomies at any number essentially just like what’s being asked here, and then a more stringent group, which they came up with the hematocrit goal of 45 and below. Or below 45.

And the trial was actually stopped early because it showed a four-fold decrease in cardiovascular morbidity and mortality. That means, four times less chance of people having cardiac events or cardiac deaths in the stringent phlebotomy group. That is when you put the goal below 45. Yes, it’s only one study, but it’s with several hundred patients with P. Vera in a nice controlled situation. So, that has become a lot of us – for us, the de facto of standard of care.
So, I would advise, if you’re a higher risk patient with P. Vera, the so-called triple therapy approach, where you’re doing, you know, baby aspirin if you qualify. The phlebotomy goal of 45 and below, and then of course, cytoreductive therapy if you need it in the higher-risk situation. So, 45 and below, it should be validated, we should do more studies here in the States, but that’s something that I think we can use with high-level data.

Andrew: Okay, thanks. Here’s a question we got in from Kimberley. She says, “My daughter is 22, she was diagnosed in 2013 with ET, and she’s been on Hydroxyurea, but is decided she no longer wants to take the med. What should she be aware of, or cautious about, given that she’s no longer taking it?”

Dr. Pemmaraju: Ugh. Well, this is an area that’s very dear to me and very important to my research. With our group here, with Dr. Serge Verstovsek and my colleagues, we just published a paper on our experience with adolescents and young adults with MPN, or AYA. As its own separate field, AYA cancer has become a very important understanding that really didn’t exist, in my opinion, 20 years ago. But our patients are not always older patients. So, young patients can get MPN, too. Yes, patients in their teens and twenties can get them just like this questioner.

So, this is a type of patient that I’m seeing quite commonly in the clinic. Couple of points to say. One is, who can blame her? Who wants to take a life-long, indefinite oral chemotherapy that may or may not have short-term and long-term side effects? In our study what we found is, approximately 10 percent of our patients met this definition. The NCCN gives it, I think, age 16 to 39. So, younger than 40. And out of those patients, I was surprised to see that a good seven percent had a thrombotic event. That means a blood clot, either at the time of diagnosis just prior to, or just after. Well, that’s a pretty good clip, and that would be more than the general population than what you would expect.

The problem with the young patient with MPN has several issues. One is, what about at the time of fertility and pregnancy? Two, what about at the time of surgical procedures? I’m talking about routine things, such as dental and other care. And then three, as they start to transition into their older adult years. So, in this patient’s case, this is a very difficult thing. We don’t have many drugs. We have Hydroxyurea, we have Interferon, which possibly might be better for a younger patient. If someone has myelofibrosis, there’s no age requirements. So, if you qualify, then the JAK inhibitor, as a class.

But this is just one of those in-between, vulnerable populations, and we really don’t have great treatments for in general, an AYA cancer, and specifically here. And so, the main thing that we would say to this person is, really, really close follow-up early on with an MPN expert, as you always advocate. Two, is at the time of fertility planning, pregnancy in our family planning is to have high-risk maternal-fetal experts involved early on. (I think, this is something important.) And three, really cautious planning in and around surgical procedures, looking for bleeding and blood clots. I think those are some basic guidelines for anyone to follow.

Andrew: Well, great advice for mom and daughter. I wanted to post this, just a quick question from Caroline who lives in the United Kingdom is diagnosed with primary myelofibrosis four years ago at age 49. And she said, “I’ve tried to find others with myelofibrosis of a similar age, but so far no luck.” So, is being diagnosed at her age, age 49 with myelofibrosis, unusual?

Dr. Pemmaraju: There you go. That’s perfect. So, that also goes along with our “Young people get MNPs as well.” This was a disease – first of all a disease, now we recognize it as a cancer that was thought to be 60, 70, 80, 90 and older. And now we realize that there’s a significant subset of our populations diagnosed in their teens, twenties, thirties, and forties. So, we definitely want our question – our viewer to know, no, you’re not alone at all. Please, see our paper that we just put out there and several other of my colleagues, including Brady Stein and others.

Two is, my goodness. Not only you’re not alone, but I actually believe – and I know you know this too – that a lot of rare cancers are sometimes are under diagnosed and underappreciated. It does require expert bone marrow, expertise, someone to identify it, someone to do a bone marrow. And lastly, for this patient looking for other patients, I would refer them to sources, such as this one. Patient Power, support groups on Facebook, we have a Twitter feed, as you know, a grassroots Twitter, that’s investigators initiative called #MPNSM (myeloproliferative neoplasm on social media).

So, there are lots of different ways for this person to connect with not only younger patients with the disease, but also as a support group, virtually. And I think platforms, such as Patient Power, have frankly revolutionized the way people have obtained information, have communicated with each other, and specifically for a patient like this in the UK, who is not able to connect with me. And when there are people all over the world waiting to talk to her.

Andrew: Right. I wanna call at our friends in the United Kingdom, MPN Voice.

Dr. Pemmaraju: Oh, yes.

Andrew: It’s Claire Harrison, who you mentioned, wonderful, devoted.

Dr. Pemmaraju: Outstanding.

Andrew: She’s an expert, out of London, helps run it. So, please, connect with them. Okay, here is a question from Erin, as we’re getting near the end of our program. “Can ET ever cause systemic inflammation? And is that what causes symptoms? The inflammation.”

Dr. Pemmaraju: Yes, yes, and yes. So, inflammation, I think, used to be a word that may have been potentially, if I may say, a wastebasket term, but now is a very specific term. So, now we know that a lot of our hematologic disorders and malignancies lead to a high level of inflammation. That means tissue damage. Tissue injury. That’s what inflammation means. There are some conditions that the patient does not even have a blood cancer diagnosis, but has a molecular mutation, that’s called CHIP (clonal hematopoiesis of indeterminate potential), and those patients appear to have a higher likelihood of cardiovascular disease and death. That’s New England Journal of Medicine. The likely pathway is inflammation.

In our patients with MPN, even the quote on quote, earlier stages, such as ET and PV. This is a disease of cytokines and inflammation. So, high levels of abnormal messengers and signals. So, yes, inflammation is part of the disease, patients have a higher rate of cardiovascular events and death. That’s inflammation. And then of course, the bone marrow milieu itself, as it progresses to myelofibrosis has an up ramp, if you will, of cytokines and inflammation. Last part of it is the therapies that we’re working on are trying to either target inflammation itself, or to bring down that level.

Andrew: Okay. I wanna see if – Here’s a – one that just popped in as we get near the end of our program. Roger says, “Are there any drugs being studied that improve anemia in patients with a low hemoglobin?” What’s the easiest way to find out about clinical trials if you live out of the state, or out of the country where this trial may be –?

Dr. Pemmaraju: Yes. Your best resource to look that up is run by the Federal Government, the NH, it’s called clinicaltrials.gov, that’s dot G-O-V. This is an outstanding website, well curated, updated as quickly as they can, and it has a nice search function. You can search by investigator, disease type, condition, and there’s even a box for ‘other’ where you can type in something like ‘myelofibrosis’.

There are several drugs in development. These drugs are known as Luspatercept and Sotatercept, for example. And they’re a class of drugs that are anemia targeting in myelofibrosis and myelodisplastic syndrome. So, the answer is, yes. And you can find out these types of clinical trials either online at this website, or at other websites. But this is an important, urgent, unmet medical need that we are working on, and there are active clinical trials for patients to enroll on.

Andrew: Well, okay. And the last thing I would ask you about – and this always comes up, Naveen, but I wanna hear what you have to say is somebody we have people with ET, we have people with PD, MF, and we talked at one end about acute myeloid leukemia. What do we know about progression now? So, if I’m sitting there with ET, am I necessarily going to go onto PV, or MF? Or anywhere along the line, and how do we know?

Dr. Pemmaraju: We do know a little bit more. So, the answer is no. So, a lot of our patients do stay in the chronic phase, as you’re asking. So, if you’re ET, or PV – and our European colleagues have really done these nice population studies, where the majority – the vast majority of patients with ET and PV are expected in the modern era to have normal life expectancies as long as you’re mitigating in some bleeds, clots, and these type of events.

But for the minority, who don’t have a normal life expectancy, you’re talking about progression to AML, which is a minority of all these. Right? Maybe 5-7 percent of cases at the most. There are some things we have identified. One is that there are some dynamic acquisition of molecular mutations that are happening at the time of progression. And what I mean by that is, there are new injuries to the DNA that people appear to be picking up. So, two important studies our colleague, Raajit Rampal showed that the acquisition of TP53 mutation, which is the guardian of the genome present in 50 (five, zero) percent of human cancers. That looks like it’s more common when ET and PV are trying to take off to AML.

Another study by our Mayo colleagues just published in Blood Advances showed that other mutations, such as PTPN11, or RUNX1, just to name some particular ones, and then we’ve known about ASXL-1 now for a while. So, rapidly change in blood counts in concert with new molecular mutations, and then a baseline if you have high-risk mutations. That seems to be a way for us to predict who might transform faster than others.

Now, that’s an addition to the traditional risk factors that you and I have already discussed, the IPSS risk, or etc. So, there are some ways that we can monitor. A lot of these may be in the research setting. Some are ready for the clinic, but there are some ways now.

Andrew: Okay. So, ladies and gentlemen, I hope this program is been worthwhile for you. Remember that the big meeting of Dr. Pemmaraju and his colleagues from around the world with thousands of hematologists is this the American Society of Hematology meeting, which once again, will be, yay, near me, in San Diego.

Dr. Pemmaraju: Very good.

Andrew: Esther and I’ll just drive over. And the Patient Power team will be there, the Patient Empowerment Network team will be there. So, we’re there for you. So, look for more programs as we go through the fall, and certainly in December, when this meeting happens. And that’s where a lot of the research that Dr. Pemmaraju talks about is presented.

Dr. Pemmaraju: Right.

Andrew: And then we’ll have more news. So, we’re living with these long-term conditions, thank god for most all of us, and it’s a moving target, as I’ve described. I wanna thank you for joining the Patient Empowerment Network program, for sponsoring this program. We thank Incyte Corporation for its support, and Dr. Naveen Pemmaraju from M.D. Anderson, and the Leukemia Department there, thank you for being a partner in this, and just explaining things, and your passion. And Naveen, again, back to your whiteboard back there. Figure it out.

Dr. Pemmaraju: It’s all there. Yes, sir, Andrew.

Andrew: It’s all there. Figure it out. Okay? All right. Thank you so much for being with us from around the world. We love it. We’ve got a community. This is what it’s all about and we’ll have future ask the expert programs. I’m Andrew Schorr near San Diego. Thanks to the Patient Empowerment Network for making all this happen. Remember, knowledge can be the best medicine of all.

What Does It Mean To Be An Empowered Patient?

The term “patient empowerment” is among the top buzzwords in health care circles, but as with many buzzwords, they can mean different things to different people.  The term is most often used to emphasize the value of having patients assert greater control over their health and health care.  WHO defines empowerment as “a process through which people gain greater control over decisions and actions affecting their health” (WHO 1998).  This shift is due in large part to the use of technology that facilitates increased patient access to information via the Internet, peer-to-peer sharing, consumer health devices, and mobile apps.

In a recent Twitter chat, I set out to explore what it means to be an empowered patient today.  The global participation of those who shared their views on the topic shows that patient empowerment is something of universal interest.

Seven Essential Components of Patient Empowerment

1. Information

Information is fundamental to the process of patient empowerment.  Rare disease advocate and parent, Anne Lawlor (@22Q11_Ireland) believes that “an informed educated parent is an empowered one.”  Patients make the best decisions when armed with the right information.  To make genuinely informed decisions about our treatment we must have access to the relevant information needed to make those decisions. “Being informed is key to empowerment for me,” says specialist palliative care social worker, Deirdre McKenna (@KennaDeirdre). “Accurate information, clearly communicated and an available space to discuss and explore options and choices.”

Research shows that access to the right information, at the right time, delivered in the right way, leads to an increase in a patient’s desire and ability to take a more active role in decision-making.  Open and transparent communication and access to a patient’s own medical records is a key driver of patient empowerment. Medical Director and Consultant Surgeon, Dermot O’Riordan (@dermotor) believes to truly empower patients “we should be aiming for the “Open Notes” principles of default sharing of all documents.”    As patient advocate and CEO of Medistori Personal Health Record, Olive O’Connor (@MediStori) points out, “the patient is at the very core of every single service they use – they know everything there is to know about themselves, in the home and outside of it. Yet patient records are not kept with them!”

The OpenNotes initiative began in 2010 as a year-long demonstration project, with 105 primary care physicians at three diverse U.S. health care centers inviting 20,000 patients to read visit notes online through patient portals. Findings from the study suggest that shared notes may improve communication, safety, and patient-doctor relationships, and may help patients become more actively involved with their health and health care.  Evidence also shows a sixty percent improvement in the patient’s ability to adhere to medications, a major problem with managing chronic pain conditions. What is key to the discussion on patient empowerment is that this initiative “demonstrates how a simple intervention can have an enormous impact, even absent advanced technology” (my emphasis).

2. Health Literacy

While access to information is a key driver of patient information, health literacy is  defined as “the degree to which individuals have the capacity to obtain, process, and understand basic health information and services needed to make appropriate health decisions.” (National Library of Medicine).  Health literacy should come before digital literacy. “Health literacy is crucial,” says healthcare analyst, Matthew Loxton (@mloxton), “and you cannot get empowerment without health literacy.” Soo Hun (@soo_cchsc), Programme Manager at the Centre for Connected Health and Social Care, believes “digital is a key aspect but health literacy, even basic literacy is a must. Not all things digital requires tech know-how but all health information requires basic literacy. An app for meds reminder is no use if a patient lacks understanding of why medication is needed in the first place or why they need to be taken promptly.  We spend too little time transferring knowledge to patients.”

This transfer of knowledge is crucial to the empowerment process, according to Olive O’Connor. “At the first point of contact with the patient,” she says, “education on how, what, why, where and when in relation to a condition or medication should be talked through fully. All other tools (digital, leaflets etc.) should come after the conversation which is key to empowerment.”

3. Digital Literacy

Cornell University defines digital literacy as “the ability to find, evaluate, utilize, share, and create content using information technologies and the Internet.”  It’s interesting to note that opinions vary on whether digital literacy is essential to patient empowerment. RN turned patient advocate and health activist, Kayoko Ky Corbet (@kkcorbet) doesn’t believe that “digital literacy is an absolute requirement, but the ability to find accurate relevant information, and understand the information is.” Breast cancer advocate, Jennifer (@vitalfrequencis) agrees that “digital literacy is not fundamental and should not be part of the equation. Empowerment needs to be across all socioeconomic groups. Otherwise…a whole bunch of patients may never be empowered.”

Dermot O’Riordan is convinced that “whilst it sounds nice to say that digital is not ‘necessary’ for patient empowerment, in practice it is going to be pretty tough to do it properly/completely without digital.” Transplant recipient and rare disease patient, Carol McCullough (@Imonlyslightly ) also believes “digital literacy strengthens the empowerment process.” She too points to “access to your medical information online” as a key component of the empowerment process. “Knowing your personal medical data is strength, as is education about your illness,” she says.

Maternity campaigner, SeánaTalbot (@SeanaTalbot) believes that “those with long-term conditions and access to technology have a better chance of accessing information and support.”  Indeed many patients have found in the online world of peer-to-peer healthcare an environment in which they are supported to become a more empowered participant in their healthcare. As I look back on my own empowerment journey, my progress was advanced step-by-step by learning more about my disease initially from doctors, then through Internet searches, and most helpful of  all  through patient peers online. Finding and being part of a patient community can be an important step on the path to empowerment.

4. Self-Efficacy

Self-efficacy, as it relates to healthcare, is belief in your ability to effect change in outcomes so that you can achieve your personal health goals. The patient empowerment definition which comes to us from the European Patient Forum describes empowerment as a process that “helps people gain control over their own lives and increases their capacity to act on issues that they themselves define as important.”

Developing a sense of personal control over your health is in itself empowering. The empowered patient is confident in their ability to manage their condition. When unsure about where to go or what to do next they will feel confident to ask questions of the healthcare professionals providing their care.  This confidence comes easier to some than others, and even the most confident may need guidance from their doctors in managing their disease. Endocrinologist, Iris Thiele Isip Tan, MD (@endocrine_witch) points out that “some of my patients are surprised when I teach them how to adjust/titrate insulin doses. Apparently not all MDs ‘allow’ this. Some need handholding because they get anxious about the responsibility.”

Digital leader and physiotherapist, Linda Vernon (@VernonLinda), believes “for authentic patient engagement to occur, we need to establish what the patient brings to the table, something akin to an individual, personal take on Asset-Based Community Development – perhaps we could think of it as Asset-Based Personal Development, supporting the patient to tap into their own internal, community or environmental resources to improve their health and wellbeing.  Engaging patients should be as much about exploring what they can do for themselves and to help the health and care system, as what we professionals can offer to the patient.”

5. Mutual Respect

The healthcare professional is the most important contact point for the patient and the system and (dis)empowerment often manifests in the patient/professional relationship. At the heart of the empowerment approach is seeing the patient-professional relationship as a partnership of equals.  Carol McCullough describes it as a reciprocal process of “mutual respect for what each person knows and being allowed to make informed choices. It is not about command and control.”

This is a partnership approach that seeks to balance clinician expertise with patient preference. It recognizes that while healthcare professionals are the experts in their knowledge of a disease, patients are the experts by experience. The empowerment process is about sharing both knowledge and experience to set new goals and learn with and from each other. Dr Kit Byatt (@Laconic_doc) agrees. “Many patients are experts”, he says, “especially rare disease patients.  I’ve learned from many in my career.”

Building better relationships and seeing the patient as more than ‘just a patient’ was a recurring theme in the Twitter chat. Elena Vaughan (@StigmaStudyIE), who is researching the impact of HIV-related stigma in Ireland, believes that “an empowered patient is treated with respect, involved in shared decision-making regrading care and treatment, and is not patronised. For people with chronic conditions, effective communication, continuity of care and establishing a relationship of trust is very important.” Sometimes, as ME blogger and patient advocate, Sally Burch (@KeelaToo) points out, “not all patients are lacking confidence to speak. The problem is being heard.”

Patient and community advocate, Triona Murphy (@Murpht01) advises doctors to get to know your patients as individuals.  “Know your patient!!…and their family,” she says. “No one size fits all! BUT there was/is still a culture of the ‘person’ stops at the door of the hospital and that person is now a patient.’”  As antibiotic resistance campaigner, Vanessa Carter (@_FaceSA) says, “I might be a patient but I am also a creative director by profession. No one recognises me on that level. They see me as an underdog.”

6. Shared Decision Making

This partnership approach allows for Shared Decision-Making (SDM) – the conversation that happens between a patient and clinician to reach a healthcare choice together. Examples include decisions about surgery, medications, self-management, and screening and diagnostic tests. There is ample research which suggests that health outcomes are better in patients who are more involved in decisions about their treatment.

In the SDM model, the clinician provides current, evidence-based information about treatment options, describing their risks and benefits, and the patient expresses his or her preferences and values. Matthew Loxton points to how seldom we have metrics to track whether patient goals are being met. “Yet this,” he believes, “is THE most important part of quality.”

7. A Facilitating Environment

Linda Vernon defines patient engagement as “activating the person’s inner assets and supporting them to make the best use of them.” Being supported is a key component of patient empowerment. Many patients would like to take more responsibility for their own health and care, given the opportunities and support to do so. Empowerment does not happen in a vacuum: it is a two-way process. The patient needs a counterpart in the health professional who welcomes the patient’s involvement and knows how to create an enabling healthcare environment. Kayoko Ky Corbet states she became an independent patient advocate when she realized most doctors simply do not have the time (and often skills) to take this facilitating role and promote shared decision-making that patients desperately need. As Patient Critical Co-op (@PatientCritical) puts it, “if you have a patient who wants to advocate for themselves, and become informed, you also need a doctor that respects the patient’s right to share decision making.”

Is It Empowerment or Participation?

Not everyone likes to use the term “empowerment”, as it implies that it is an authority given to someone to do something. “I balk at the idea that professionals can ‘give’ (usually on their terms) power to the powerless,” says Alison Cameron (@allyc375). “We need to create conditions whereby people can “empower” themselves.” Seána Talbot agrees that patient empowerment “doesn’t mean ‘giving’ people power.’ Rather it’s about ‘enabling’ them to recognise and use their power.”

Perhaps the term ‘participation’ (which is a more active state) is preferable? This distinction is important because empowerment cannot be imposed ‘top down’ (although it can be facilitated).  Sharon Thompson (@sharontwriter) believes that “patients should not be pressurised or need to be in a position of ‘power.’ It should be automatic that a patient is central and key to their care. Patients are automatically empowered when they are respected as being people who are entitled to understand and know about their care.”

Neither is patient empowerment about the patient taking full control or shifting responsibility to the patient.  “If the empowerment amounts to abandonment”, says Matthew Loxton, “then the patient’s health goals are not being met. Patient empowerment should never be an excuse for abandoning or burdening the patient.”

Rather, the empowerment approach, as defined by the European Patient Foundation (EPF) “aims to realise the vision of patients as ‘co-producers’ of health and as integral actors in the health system.”  Caregiver Reinhart Gauss (@ReinhartG) agrees that “patient advocates want to work with not against doctors – to share experiences and to grow in knowledge.”  Vanessa Carter is clear that “we still want our doctors, but they are not there 24/7 so patients need the right tools to make self-care possible.”

Equally, it is about recognizing that there are degrees of involvement and not all patients wish to be ‘empowered.’  There is a spectrum of interest in wanting to assume an active role in care – from being passively receptive to fully engaged. It is up to the patients themselves to choose their own level of engagement. Pharmacist Chris Maguire (@chris_magz) sees this choice as the essence of empowerment. Patients “get to decide how much they want to look into things and take control. Or they want to be guided on the journey and have trust in their healthcare providers. But the key is that they decide the level of interaction and are not dictated to.”  Kayoko Ky Corbet agrees that “true patient empowerment should be about helping patients get involved at their highest potential or at the level they choose.” However, she says “it’s also important to keep the option of involvement open. Ideally patients should get opportunities to change their minds to participate in decision-making later.”

Empowerment as an Ongoing Process

Empowerment is a non-binary, non-linear process. Your needs may change over time. You might feel empowered in a certain context, but disempowered in another. Healthcare communicator, Michi Endemann (@MichiEndemann) makes the distinction that “talking about empowerment as a healthy person is quite different than talking about it as a patient.”  As patient advocate, Rachel Lynch (@rachelmlynch) puts it, “it can be quite tiring being empowered when all you want to be is well.” A sentiment echoed by Kathy Kastner (@KathyKastner), founder of Best Endings, who clarifies how “to me ‘empowered’ assumes I’m feeling physically and mentally up to the task of ‘being engaged’. I’ve seen powerhouses who cannot bring themselves to take responsibility for their own health.”

Mental health advocate and co-founder of #DepressionHurts, Norah (@TalentCoop) calls attention to the fragile nature of empowerment. “Even the strongest can quickly feel disempowered by a deterioration in health,” she says. “Fear disempowers. Sometimes it’s a case of ‘can’t’ not ‘won’t.’”

For those who feel ready for a greater degree of participation in their healthcare (and that of their family and loved ones), Jennifer advises that “being willing to self-advocate, along with self-confidence, communication skills, compromise, research skills, and relationship building” are some of the key traits and skills you need to become an empowered patient. Terri Coutee (@6state), patient advocate and founder of DiepCjourney Foundation, adds that “empowered patients do their research, ask questions, go to appointments organized, and take a friend to help listen.”

Barriers to Patient Empowerment and Overcoming Challenges

What are some of the current barriers to involving patients more in their care? Jennifer points to a “lack of adequate time during the doctor’s visit (on both sides), language barriers, technology barriers, generation gaps, and cultural gaps.”  The solution?  “All solved by building good relationships,” says Jennifer.

Norah also calls attention to the technology barriers. “For older patients simple things like communication (hearing), or uninformed changes are extremely disempowering; as is over reliance on technology for a generation who may not have ‘tech’ understanding or access.”  Tim Delaney (@FrancosBruvva), Head of Pharmacy at a leading hospital in Ireland highlights the fact that “in acute hospitals we treat huge numbers of elderly people whose engagement with social media and new technology is lower. We need to design technology that meets their usability needs AND use whatever suits them best be it old tech or new.” Soo Hun agrees that “the tech savvy few have quicker and better access to health information and therefore can have choice and autonomy. To reverse that we need to make technology ubiquitous and make health information and choice easily accessible.”

Whilst Vanessa believes it should be “governmental policy to have digital resources in place, for example, disease specific websites / apps supported by health authorities,” Kayoko believes it can start with “tech-savvy advocates (like me) who could help patients learn to use simple digital tools.”

Matthew Loxton sees a core barrier to empowerment to be “the large knowledge/power gradients between patients and health care providers. Without access to their data, trustworthy sources of medical knowledge, and the power to execute their choices in achieving health goals, empowerment is an empty phrase.”  Triona Murphy echoes this systemic challenge by clarifying that “the whole system needs to understand the patient’s right to be equal partners in their care. IF that is what the patient wants.”

Sometimes the fear of being labelled a difficult patient can be a barrier to empowerment. “Some patients feel uncomfortable challenging the judgement or actions of their caregivers for the fear of being labelled as ‘difficult’, of offending staff and/or because of concerns of compromising their healthcare and safety,” says Tim Delaney.

Final Thoughts

Not everyone wants to be empowered in making decisions about their care, and not every doctor wants to take the time. Some doctors use medical terminology which is incomprehensible to patients, while some patients have low health literacy skills or come from cultural backgrounds that lack a tradition of individuals making autonomous decisions.  That said, Carol McCullough points out that while “not everyone may want to be empowered, for the health service to be sustainable, more people are going to have to take on more responsibility.”

Medical Doctor and Chair of Technical Advisory Board, Pavilion Health, Dr Mary Ethna Black (@DrMaryBlack) points to the inevitability of the shift towards patient empowerment. “Empowerment is an inevitable shift that is happening anyway, “she says. “We cannot turn back the tide or turn off the internet.”

Kayoko Ky Corbet agrees that we “must understand that patients making informed decisions is the ultimate way to reduce waste, pain and regrets in healthcare. It’s also morally the right thing to do!”  Patient Critical Co-op also believes in the moral imperative that “empowerment essentially means a group or society recognizing your right. Patient empowerment exists as an action patients can take to improve themselves, but the key to achieving that improvement is having a group, organization, or state enshrine and recognize those rights.” In fact, the Alma Ata Declaration defined civic involvement in healthcare as both a right and a duty: “The people have the right and duty to participate individually and collectively in the planning and implementation of their healthcare.” The Declaration highlights the collective dimension of empowerment and the importance of action towards change. By working together to think internationally and act nationally we can draw on each other’s experiences so that as individuals and as a collective we can work towards better outcomes for all patients.  To quote Terri Coutee, “When we gather our collective empowered voices, we feel a strong responsibility to give voice to others.”

MPN Patient Story: Ruth Gerwin

My journey began in 1999 when I was diagnosed with Essential Thrombocythemia (ET). All I took was a baby aspirin, even then they [platelets] soared to over 1 million.

In November 2004, I had a bad cold and had this aching on my left side. It was discovered my spleen was enlarged and I had a bone marrow biopsy. I was at that time diagnosed with Myelofibrosis (MF). I went to see Dr. Richard Silver in New York and he put me on Interferon. I saw him for 5 years and then transferred to Cleveland Clinic as my insurance company was making it harder and harder for Dr. Silver to be paid. There I was under the very capable care of  Dr. Ramon Tui. It was under his care that I did a trial for Jakafi. It only helped the spleen size for a couple of months, but it has kept some of the other side effects of the disease at bay. I still take 20 mg. twice daily. Also, in 2014 I had a double mastectomy.

In the spring of 2017, I was so horribly uncomfortable because by this time I looked 9 months pregnant with my spleen. I also had swollen legs and feet. I could hardly walk. I made a decision at that time to radiate the spleen to give me some relief. I was supposed to receive 10 treatments, but was stopped at 7 because my blood counts bottomed out. Hmg 6.0, Pl 5, WBC 0.8. I started with transfusions twice weekly of one platelet and two blood. I did this for several weeks and developed a horrible headache. I stopped the transfusions and my Dr. said to go home and call Hospice. He thought I had 2 weeks to 2 months to live. I was really sick, but as my spleen began to recover, my counts went up. By the fall of 2017, I was basically back to normal with the blood counts and, of course, out of Hospice. My family think I’m a miracle. But, the spleen, by December 2017 was becoming very uncomfortable again and I started radiation again January, 2018. This time I had 4 treatments and had to stop because of my blood dropping.

It has been suggested to me by two doctors to have my spleen removed and have a bone marrow transplant. But, I have read about this procedure and I know I wouldn’t survive as I am very sensitive to most of the medications they would have to give me. My current hematologist is looking for a trial I can do, but my bone marrow is nothing but fatty tissue. I have nothing there…not even fibrosis. I keep telling them my spleen is doing it all, but they won’t believe me. With no bone marrow tissue, I can’t do a trial. So, I don’t know what they are going to do with me. Anyone else have this problem? I’d love to hear what you are doing.

I know the Lord has a good plan for me and I just have to wait and see what it is. He is the “great physician”!  I’m just not real patient. I haven’t felt really well for a long time.

Uber Health App

The Community Transportation Association estimates that approximately 3.6 million Americans miss or delay medical care because of transportation issues that cost the health care system $150 billion each year.

To help combat this issue, Uber has created a new app called Uber Health. Earlier this month Uber announced that they are working with providers to offer reliable rides for patients, care partners, and families to get to and from doctor’s appointments and the hospital.

The app will allow medical and administrative staff to either call an Uber to drive a specific patient home, or to dispatch an Uber to the patient’s house for pick up. The app also allows users to schedule the ride up to 30 days in advance, so important appointments are never missed. Planning transportation in advance enables patients to schedule rides to and from follow-up appointments even while they are still in the healthcare facility. With the ability to schedule and manage multiple rides from a single dashboard, healthcare professionals can take their level of care to the next level with Uber Health.

How It Works

Patient Advocacy: Understanding Your Illness

The news that you, or a loved one, has a serious illness can be a terrible blow.  You may be faced with an array of emotions ranging from shock to fear to anxiety. You will likely have many questions and concerns about what the coming days and months will bring, and the impact living with this illness will have on your life and the lives of your family. Although you may be reeling from the news, it’s important that you learn as much as you can about your diagnosis, its symptoms, how it may progress and what treatment options are available. In this article, you will learn which questions you should ask your healthcare team and where to find reliable and trustworthy information to become better informed about your health condition.

1. Obtaining Information From Your Doctors And Healthcare Team

Having answers to your questions can help you understand your illness better and feel more in control about your treatment decisions.  How much information you want is up to you. Some patients feel overwhelmed by too much information at this stage.  Others say they didn’t receive enough information.  While information upon first diagnosis is vitally important, you may be in shock and in a heightened emotional state which makes it difficult to fully comprehend all the information you are given. If possible, bring a trusted friend or family member to appointments with you to take notes. If this is not possible, ask your doctor if you can record the consultation so you can focus on listening, and go back and review what was said later.

Medical care is a conversation and to have influence in that conversation you have to speak up. Never be embarrassed to tell your healthcare team if you don’t understand something they’ve said. Sometimes doctors use medical jargon without realizing they are not explaining things in terms we understand. Repeat what the doctor has told you to be sure you understand and ask for clarification if needed.

Some questions to ask your doctor about your diagnosis:

  • What are the symptoms of this illness?
  • What should you do if you notice new symptoms or if existing symptoms worsen?
  • Do you need any further diagnostic tests?
  • What are your treatment options?
  • What are the side-effects of the recommended treatment?
  • What are the benefits vs the risks?
  • What happens if you do nothing?
  • Are there other treatment options available?

Finally, ask your healthcare team if they can recommend further reading, support groups and other resources to help you learn more about your illness.

2. Finding Reliable Information Online

As you move along the patient journey and better understand your illness, you may want higher levels of information. However, you may find the information healthcare professionals provide has not keep pace with your increased needs. This is the point where many patients turn online to seek more information. While the Internet can be a useful source of health information, it’s important to know how to critically evaluate the information you find online. Always discuss what you find with your healthcare team and ask them to put the information into context for your particular situation.

Here are some questions to help you determine the trustworthiness of online sources of information.

  • Who has produced the information?
  • Does the organization have commercial interests or another reason they are promoting this information?
  • Is the name of the organization and their aims in setting up the website clearly shown?
  • Does the site provide contact details if you have any questions?
  • Is the information on the website up to date?
  • Does it cite the source of the information that is being presented?
  • Does the site link with other reputable sites that give similar information?

3. Evaluating Medical News Reports

Whether it’s published in hard copy or online, medical news reports can mislead people into thinking a certain drug or treatment is the next breakthrough in a disease.  As patient advocates we must learn to read beyond the headlines to filter out the good, the bad, and the questionable.

The following questions will help you evaluate the reliability of medical news reporting.

  • Does the article support its claims with scientific research?
  • What is the original source of the article?
  • Who paid for and conducted the study?
  • How many people did the research study include?
  • Did the study include a control group?
  • What are the study’s limitations?
  • If it’s a clinical trial that is being reported on, what stage is the trial at?

Always try to read an original study (if cited) to critically evaluate the information presented. Understanding research literature is an important skill for patient advocates. For tips on how to read a research paper click on this link.

4. Learning From Peers

From helping us to uncover a diagnosis and finding the right doctors and treatments, to learning about everyday coping tips, turning to our peers can make all the difference in how we live with our illnesses.  Much of this peer-to-peer learning takes place through social media discussions on patient blogs and in Facebook groups and Twitter chats. On Facebook you can connect with other patient advocates and join Facebook groups related to your disease or health condition. On Twitter you have a greater mix of patients, physicians, healthcare professionals and medical researchers coming together to discuss healthcare matters. It is becoming increasingly popular for attendees at key medical conferences, such as ASCO, to “live-tweet” sessions. You can follow along on Twitter using the conference hashtag which you should find published on the conference website. Another way to learn on Twitter is to join a Twitter chat related to your health condition. Twitter chats can be one-off events, but more usually are recurring weekly chats to regularly connect people. There are chats for most disease topics and a full list can be found by searching the database of the Healthcare Hashtag Project.

Final Thoughts

Understanding your illness is the first step on the path to advocating for yourself and others.

Being an advocate involves asking lots of questions, conducting your own research, and making your preferences known to your healthcare team. By doing this, you will be better informed and in a stronger position to get the treatment that is right for you. If this feels overwhelming to you right now, go at your own pace, and reach out to others who have walked this path before you. There is an army of patients who are standing by, ready to share their healthcare wisdom and practical coping tips with you. Seeking their advice will help lessen the fear and isolation you may be feeling, give you a sense of shared experience and connection, and help you feel more in charge of your healthcare decisions.

Fact Checking 101: Health Literacy in Real Time

There’s a medical miracle every day, if you believe headlines on popular media sites. If you just read those headlines, cancer is cured daily, as are hepatitis C, and a host of neurological conditions. Dive into the stories, though, and you’ll all too often find the “in mice” red flag, meaning that scientific experiments have indicated that mice are having terrific outcomes from whatever substance is being touted. Humans? Not so much.

Information flows at the speed of life – thank you, Internet – but information does not always equal factual truth. Which is where fact checking comes in, and what I’ll be offering tips on here. As a journalist, I’ve hunted down confirmations on stories for years – here’s a quick primer on doing it for your own health/science literacy building.

  • Snopes.com: this site is the granddaddy of online myth busting. They have a dedicated channel for health news, which is definitely a good first stop to fact check a headline touting a “cure” for an illness or condition.
  • Sense About Science USA: the US arm of the UK-based Sense About Science and AllTrials, this site takes a deep dive into advocacy and literacy building for both the public, and professionals, around medical science. They’re in the process of creating an AllAccess Patient Guide on clinical trial participation, and transparency in reporting on all trials, which will be published in the fall of this year (2017).
  • Health News Review: the editors and reviewers behind this site are professional healthcare journalists dedicated to reading and scoring the reporting on health science in major media. I think of them as Politifact For Healthcare – they don’t issue “pants on fire” or “Pinocchio” warnings, but their 5-star review system is rigorous, and great reading.
  • FactCheck.org and FlackCheck.org: these sites assess news stories and sources in many categories, from politics to science to health policy. They’re produced by the Annenberg Public Policy Center at the University of Pennsylvania, and are great resources for fact checking in all news categories, not just science.
  • Retraction Watch: this is in the Super Science Nerd Journalist zone, covering the retraction of scientific papers around the world. There’s an old news adage about corrections being buried deep beneath the front page – that rule goes double in science publishing. A paper is published, and makes big headlines. If it’s retracted weeks/months/years later, there’s seldom a screaming headline announcing the retraction, leaving the untruth out there to be misunderstood and often misused.

Building your own health and science literacy is a process. Reading the latest medical science news is a starting point, but you have to add fact checking as a critical part of your learning curve. Then use the “see one, do one, teach one” method to help your friends and family build their health literacy, teaching them how to find and fact check the science news that matters – that’s how we all build healthy, science-literate communities.

Living Well with MPNs – What You Should Know About Genetic Mutations

What You Should Know About Genetic Mutations

Living Well With MPNs: What You Should Know About Genetic Mutations from Patient Empowerment Network on Vimeo.

Should you get a genetic test? JAK2, MPL, CALR, ASXL1: Mutations associated with myeloproliferative neoplasms (MPNs) can bring up lots of questions. What do they mean, and how do they impact your disease? The goal of this webinar, featuring Dr. Alison Moliterno from Johns Hopkins School of Medicine and Dr. Stephen Oh from Washington University School of Medicine, is to help patients understand genetic mutations.


Transcript:

Andrew Schorr: Hello and welcome to this Patient Empowerment Network program, produced by Patient Power. I’m Andrew Schorr joining you from Carlsbad, California. Over the next hour we’re going to talk about something that’s very personal to me and probably to you, and that is the whole idea of genetics related to living with an MPN. What does it mean? Does it change over time? What is your version of an MPN? What does it mean for prognosis? What does it mean for treatment? What does it mean for clinical trials opportunities? So we’re going to be discussing all of that.

I want to thank our sponsor, Incyte Corporation for supporting this educational activity. We’re going to cover the country and we invite your questions as we go along. Send them to MPN@patientpower.info. Many of you have. And remember if you have to bow out at some point, the replay will be available and we’ll have video clips. So we’ll reach literally a few thousand people living with MPN worldwide, and we’re happy to do that.

Let’s get started. First I want to introduce you to one of our medical experts who’s joining us. He’s been on programs before. He joins us from Washington University and the Siteman Cancer Center in St. Louis; that’s Dr. Stephen Oh, who is an MPN expert there. Dr. Oh, thank you so much for joining us.

Dr. Stephen Oh: Hi, Andrew. Thanks for having me.

Andrew Schorr: Thank you, Stephen. Okay, let’s go from St. Louis to Baltimore, Maryland and the Johns Hopkins University Medical Center and another expert in MPNs who’s been with us before, and that is Dr. Alison Moliterno. Dr. Moliterno, thank you so much for being with us today.

Dr. Alison Moliterno: Thank you, Andrew. Thank you for having me.

Andrew Schorr: Sure, pleasure. We’ve got a lot to cover. And then also I want to welcome back one of the members of our community, someone who was diagnosed many years ago, a couple of decades ago with ET, and then a year ago it became myelofibrosis. She’s a preschool teacher in Peoria, Illinois. She’s been with us on our programs before; Marsha Krone. Marsha, thank you for being with us once again.

Marsha: Thank you. Hi, Andrew.

Andrew Schorr: Marsha, let’s visit for a minute. I was diagnosed in 2011 and then eventually had a genetic test which came up with a bunch of results. One of them for me, if I get it right, JAK2V617F.

I had no idea what that was, and then a couple of other genes that to me seemed kind of like alphabet soup. And I had one of the peers of these experts here, Katrina Jamison. We went over it and she said I think it’s the JAK that’s kind of driving things. We’re going to talk about what are the driver genes, and what may not be, or what do we know at this point. Marsha, you had a genetic test, too. What did it say?

Marsha: My genetic test came out as Calreticulin type 2.

Andrew Schorr: Okay, so we’re going to figure out what that means. Dr. Oh, let’s start this way. People think genetics. I know genetics maybe had something to do with being bald, and I see you have a similar hairline; or dark hair, or brown eyes, or whatever. Hereditary genes; are we talking about that or are we talking about something different?

Dr. Stephen Oh: That’s a basic question that comes up with almost every new patient that I see.

The short answer is that when we’re talking about genetics with relation to the MPNs, we’re not talking about those kind of things that you’re born with that may affect your hairline and whatnot. These are genetic mutations that are acquired over time that you’re not born with; they’re not passed down to your children or your relatives, etc. So that is a very important distinction that I try to make clear with every new patient that I see.

Andrew Schorr: Okay, and one follow up question to you. People say okay, Doc, what gave me this genetic injury, if you will, to lead to these illnesses? Do we know?

Dr. Stephen Oh: That’s another question I cover with almost every new patient; that I think for that one I guess the answer is a little less satisfying. My answer is that for the most part it’s random chance.

What I mean by that is that we know particularly from research that’s come out n the last five or so years that all of us acquire mutations randomly over time as we age. But fortunately for most individuals, those mutations land in spots where they really have little to no consequence. But for those that, for instance, acquire the JAK2V617F mutation or acquire a Calreticulin mutation, that really becomes most likely the main driver for what ultimately becomes an MPN.

Patients of course ask did I do something wrong, was I exposed to something? And while we can’t necessarily exclude that those are factors, I think for the most part it’s that just kind of randomly these mutations landed in the wrong place.

Andrew Schorr: Dr. Moliterno, we’ve mentioned a couple of these onco genes I think you call them – cancer genes, the JAK2 gene and Calreticulin type 2, I didn’t even know about that.

Can you first of all rattle off some of them just so we know the landscape of what are genes that seem to be associated with MPNs today, knowing that this will probably expand?

Dr. Alison Moliterno: I always like to tell patients a little bit about the history when these were first diagnosed because we talk about them now as if they’re common knowledge, but they are really quite recent in our understanding. We’ve known about the myeloproliferative diseases for more than 100 years, but it wasn’t until 2005 until the driver of many of the diseases was understood to be JAK2V617F. So that discovery occurred in 2005. Before the JAK2 discovery, we didn’t understand really if it was acquired mutations and what genes were involved. JAK2 is the most common of these.

If you look at 100 patients with the classical MPN, meaning PD, ET, and myelofibrosis, 75 percent overall of those individuals will have the JAK2V617F mutation. Not long after the JAK2V617F mutation there was a discovery in mutations in M-P-L or MPL. That accounts for about 5 percent of those 100 individuals with either ET or myelofibrosis and then in 2013, that was the discovery of the calreticulin mutations that comprise about 20 percent of individuals who have ET or myelofibrosis. So 2013, that’s fairly recent and those are the three drivers.

I like to say that if you could put the same mutation, the JAK2V617F or Cal or MPL mutations that we see in our patients, if you could put those, say, in a mouse; they would drive a similar disease in the mouse so that you get polycythemia vera in a mouse if you make the mouse have the V617F mutation. That’s how we’ve kind of come to understand that they drive the disease. They may not drive all aspects of it but they drive the basic process.

Andrew Schorr: I know there’s another gene that people have seen too; ASXL1. What is that one?

Dr. Alison Moliterno: In addition to these drivers we’ve also discovered a lot of genes that seem to modify the MPN or associate with certain subtypes of MPN. So for instance I said usually JAK2 MPL or CALR can all drive platelet count high and give a disease like ET. Then what happens when patients develop myelofibrosis? We find that perhaps other lesions are acquired.

Those are genes that don’t drive myeloproliferation so much but they seem to drive the way that the chromatin or the nucleus is managed; they seem to maybe set up the other aspects of MPN that associate with myelofibrosis. And ASXL1 is probably the most common additional genetic lesion or acquired mutation that occurs in individuals with myelofibrosis.

Andrew Schorr: Okay. Dr. Oh, people may be tested and we’re going to talk about who should be tested and when. How do you know what’s the driver gene? And it sounds like this continuation of identifying genes just keeps going, too.

Dr. Stephen Oh:Certainly Dr. Moliterno gave a nice circle overview of when the three primary driver mutations were discovered.

We’re sort of lucky now that in today’s day and age we kind of look at this now as standard testing. So JAK2, MPL and calreticulin so much so that many physicians including myself, we kind of go about this in an algorithmic fashion. So for instance if I have a patient with newly diagnosed myelofibrosis, I’ll start by screening for the JAK2 mutation; if that’s negative, go to Calreticulin and if that’s negative go to MPL.

And so with those three genes, the majority of patients with any of the three main MPN subtypes, whether that’s QV, ET, or myelofibrosis; they’ll be positive for one of those three. There’s a subset that’s at least on the order of 10 to 15 percent of patients with ET and myelofibrosis who will be negative for all three of those mutations, what we’re now calling the triple negative category. But the vast majority of MPN patients will have one of these three mutations which we consider the main driver of mutations.

So, in some sense again we’re sort of fortunate that it’s become almost straightforward in terms of at least the top level genetic testing for these diseases.

Andrew Schorr: So that was my question to you, Dr. Moliterno. Some people have maybe had fights with their insurance company or their doctor as related to testing. How do you view this now and how could it be positioned on how it’s really not elected, if you will, but essential to get a clear picture of an individual patient’s situation?

Dr. Alison Moliterno: This comes up in my practice and I’m sure Dr. Oh’s practice all the time, in that in the olden days before our understanding of what causes these diseases, and again the cause was these acquired mutations and in the olden days we would use histology, looking under the microscope, looking at blood counts and sort of put a name to this polycythemia vera and myelofibrosis.

But within that was such a vast variability of what the disease actually was, that that name really did not tell us too much. Now, we’ve really come to understand that what you have is defined by these molecular lesions. They’re not just of academic interest; they actually really tell us quite a bit about what you’ve got, what your prognosis is, and where it’s going. So physicians, we really can’t function and counsel patients appropriately without this knowledge. So there’s no longer elective or of interest; it’s really critical in defining what you’ve got.

Andrew Schorr: Okay, everybody. You heard it, so this is what you’re advocating for with your MPN specialists, which hopefully you have like the two with us. This is standard operating procedure; there shouldn’t be nay question with an insurance company or anybody to help you and your doctor know what you’re dealing with

But then the next question is, Dr. Oh, where are we now even in research, where things are headed so there will be treatments that line up with the different genetic situation?

Dr. Stephen Oh: I’ll start my answer to that question by going back to when the field began to develop inhibitors of JAK2 for the treatment of patients with MPNs and extrapolating from other diseases, I think there was an assumption that the patients that would respond best or if at all to JAK2 inhibitors would be those that carry the JAK2V617F mutation. What we now know quite clearly is that even those patients that do not carry the JAK2 mutation, they also tend to respond to JAK2 inhibition. So again in the case of myelofibrosis, patients who are calreticulin mutants, they also respond to JAK2 inhibitors as well.

So that’s an example where I think in a good way the use of those kinds of treatments is not limited or defined or restricted mutational profile. But otherwise in terms of the research front, identifying or defining treatments specific to different mutations, we haven’t made a lot of headway there. For instance, you can imagine now we have identified the calreticulin mutation in many patients with MPNs; can we devise a treatment specific for that? So while again on the one hand like I mentioned, it’s a good thing that those patients do respond to JAK 2 inhibitors; can we come up with something very specific to calreticulin with the patients there?

There are certainly a number of research groups that are working on that kind of question, but we currently do not have anything specific in that regard.

Andrew Schorr: Dr. Moliterno, I want to get a question from you about that because I’m sure you’re asked. Somebody says well – Marsha could come to you and say well, I’m CALR so what do you have for me? And/or you also mentioned triple negative, and I think often I’ve heard that term in breast cancer; women who were triple negative there, and say what do you have for me in that situation? So talk to us a little bit about those situations, and does it vary now with treatment approaches yet?

Dr. Alison Moliterno: I think another aspect of this is we may not today have the specifically targeted treatment but as Dr. Oh mentioned, what we’ve learned is that these three main lesions, CALR, MPL, and JAK2 all seem to over signal or work their effects through this JAK pathway.

So even though you may not have the JAK2 mutation but you have the CALR, it seems like the end result of over signaling is in the same pathway and therefore JAK inhibitors would be beneficial in individuals who have that over signaling pathway. So that’s one thing we’ve taken away; that while even though we don’t have – and that’s a good thing because that tells us that inhibiting this pathway overall will benefit the majority of individuals with these lesions, whether they’re JAK2 or CALR or MPL.

The other thing about the profiling is how much of the mutation you have. So another I think we’ve learned is that we can measure the amount of these mutations, and that’s a variable across patients and gives us quite a bit of information about – again – the type of lesion, disease you have and gives us  better information about the prognosis and why you might have a little more fibrosis than someone else.

So again, the type of lesion you have and the amount; we’re now learning to use that information. I think another thing we’ve learned is these terms triple negative, which is a term that we understand okay, that means you don’t have any of the three drivers that we know of.

But as we’re learning more about extended mutation paneling or doing different tests to look at the entire genes, we’re finding that most of those individuals really do have lesions in the JAK2 gene, or the CALR gene or MPL that maybe aren’t in the specific areas that the test was sent for. So that’s another benefit of this revolution in being able to define these lesions personally so that your disease really can be diagnosed.

Andrew Schorr: Okay Marsha, you’ve been sitting there quietly and I wonder, is this making sense to you? You’re my co-host with this; is it making sense?

Marsha: It does make sense. When I first was diagnosed, they just said you simply have ET because you have it. Then they discovered more mutations. I like to know everything about how my body is working, so I wonder how valuable it is to have additional genetic testing to see if you have other mutations that may affect prognosis?

Andrew Schorr: Right. So Stephen, and also like serial testing at some other time? She went from ET to MF over many years, so when do you test again or how does this change?

Dr. Stephen Oh: Speaking sort of broadly at first, the more extensive genetic testing which is available through numerous laboratories now, which can test for any – quite often these panels went through 20 or 40 genes; some of them hundreds or more.

The use of those in the clinic has evolved pretty rapidly over the past three, four, five years. In my own practice five years ago I was certainly not routinely recommending that kind of testing. But today, particularly with patients with myelofibrosis, I am doing it much more frequently and the question of course is as you raised; what utility does it have in terms of prognosis.

And there especially I think in myelofibrosis, is where more and more literature has come out giving us a better handle on what effect these different mutations might have on prognosis. That’s why more and more I’m beginning to recommend this kind of testing for my patients with MF.

In the case of QV and ET, it’s a little bit further behind in terms of data to indicate what these different mutations might mean, but we have also seen more literature come out, not as often but do consider that kind of testing for those patients as well. In every case it’s kind of an individualized discussion with the patient. I always start out with how much do you want to know. Marsha said I want to know everything, so that’s the kind of patient where you say alright, well, maybe let’s do this.

Others say well, I don’t really necessarily know I’m going to interpret this; it’s alphabet soup. Do I necessarily want to know what the statistics say to expect in 20 years, etc.? Again, it’s an individualized decision with every patient.

Andrew Schorr: Dr. Moliterno, there was another patient who was going to join us who couldn’t make it because she’s being scheduled for a transplant. She’s getting her life in order for that; someone with I think myelofibrosis in the Seattle area.

But she did have three mutations identified, so let’s see if this makes sense: ALX1, if I get it right, TP53 and SFB1, if those are other ones? So the fact that she has this sort of alphabet soup, does that mean that that meant you’re headed for transplant because that shows up? You know, one knows is more – more weighty, if you will.

Dr. Alison Moliterno: This is knowledge that we’re kind of pulling in as we speak, and that the meaning of more than one mutation, different types of mutations do seem to have prognostic significance.

So as we’ve learned that generally the more mutations you have, more individuals at a certain point of time generally is concerning. It means that there’s a lot going on in that stem cell and that maybe there’s some instability to allow these mutations to occur. And then it does matter which type. Some mutations seem to have more independent prognostic than others. ASXL1 tends to be one that is seemingly more associated with developing myelofibrosis. SF3B1, one of those she has, may be a less negative prognostic indicator.

But again, these are important and having three at once is a concern, and it sounds like a reasonable plan to move forward with transplant because we understand that we don’t really have a medicine that can address all of those lesions and that this is more high risk disease.

Andrew Schorr: I want to remind our audience a couple of things. One is you’re hearing how sophisticated the testing is, and then you can imagine the interpretation.

We have two noted experts. The typical hematologist is not going to see this very often. So whether you go to Washington University, I go to UC San Diego, Marsha goes to the Lurie Cancer Center, Dr. Moliterno is at Johns Hopkins. You know some of the others where you go; you want to consult with an MPN specialist. As the data comes back, what does it mean for me now or on your journey in the future.

The other point I wanted to make is of course we want to take your questions. So send them to MPN@patientpower.info and our wonderful MPN community manager, Jamie, is standing by and she’ll be forwarding these to me. Obviously, a lot of you ask very personal questions; what should I do, Dr. Moliterno, Dr. Oh; I’ve got XYZ. And that’s not fair to do that here, so that’s our disclaimer. You want to go back to your MPN specialist – it could be one of them – to discuss it.

We did get some questions in earlier. Dr. Oh, Tammy wrote in and she said can you provide more information on being PV JAK2 negative? She says I know we’re limited in number compared to other patients. It would be nice to know the basics. How much more different are we and is our treatment any different? So, JAK negative PV.

Dr. Stephen Oh: That’s a great question and it’s a challenging question. I would say that in part because we know that in the case of PV, at least 95 percent or greater of patients with bonafide PV carry the JAK2V617F mutation and it’s at least 95 percent; it may be higher than that. And even those that are negative to the JAK2V617F mutation, there’s another small group, probably less than 1 percent, who carry an alternative JAK2 mutation, an exon 12.

 So between those two, patients with PV, again the vast majority do have a mutation in JAK2. That does leave a small sliver that you could call JAK2 negative PV, and there – it’s sort of being a skeptic – the first thing I say when I’m asked to evaluate a potential case like that is am I convinced that is the correct diagnosis? Do they truly have PV versus a potentially secondary cause of erythrocytosis?

And so there, sort of again you have to rely on the old school diagnostic criteria; do they otherwise have the features of the disease? Does the bone marrow, is it consistent with the diagnosis? Are they like a classic patient in that they have a low epo level, etc. But to get to more specifically to the question, if you’re convinced that that’s the correct diagnosis, essentially I treat the patient the same way I would treat a JAK2 positive PV patient.

In other words, I would use the same kind of treatment calls in terms of a hematocrit less than 45, treat them with cytoreductive therapy and the appropriate circumstance if they’re considered high risk, if they have had a prior history of thrombosis; aspirin considered standard therapy for these patients. Again, if I do believe that is the correct diagnosis, I essentially treat them similarly to patients with JAK2 positive PV.

Andrew Schorr: Okay, and Alison, do you concur in that?

Dr. Alison Moliterno: I do. I think we have a name for the disease, polycythemia vera, where you make too many cells due to an inherent stimulus of the bone marrow. I think now in this age, we are really coming to redefine PV as the disease that has mutations in the JAK2 gene. I’m always concerned when someone has been diagnosed with JAK2 negative PV because as Dr. Oh says, maybe they have something else.

A couple circumstances that I’ve observed is that sometimes the diagnostic testing, when it was done and it was done with JAK2V617F testing that was not sensitive enough. So again we have this issue of how much of this do you have? And some PV patients can have very low levels of the JAK2 mutation that if you use an assay in a laboratory that wasn’t very sensitive and you only detected levels of 10 or 20 percent, they would be read out as negative. That’s happened in my practice a few times where patients went high and low all over the place trying to get a diagnosis; JAK2 negative. Finally when a more sophisticated or sensitive test was done, they’re positive.

The other issue is that there are other mutations aside from V617F in the JAK2 as Dr. Oh said; there’s exon 12 and then there are some others in various parts.

So when we do some of this more expanded molecular profiling, the laboratories are able to look not just at the V617F site, which is where most tests – they only tell you yes or no at that site; but they’ll look at the entire part of the coding region of the JAK2 gene. You’ll find patients who have an unusual mutation down the way that’s like – And I think it’s important because there are some people who really don’t have a myeloproliferative neoplasm; they have something else and they’ve been told for 25 years that they have PV.

And it is nice to either make that diagnosis or not. And so I think Stephen has been in that situation also, where maybe they were labeled because that was the best information we had at the time, but they really should be reevaluated.

Andrew Schorr: And I think that’s the point for our audiences. You with the best testing, with the best specialists you can get to, you want to know what you’re dealing with; what is your situation.

Here’s a question we got so Marsh, just for you. You mentioned at the beginning, Marsha, that you have CALR type 2. Can you describe that? So let’s make sense of that. There was a support group leader, Kim, who wrote in. Kim wanted to know how do CALR types 1 and 2 manifest and progress? Dr. Oh, what’s the difference between CALR1 and CALR2? What does it mean?

Dr. Stephen Oh: There are a variety of different types of mutations in the calreticulin gene, but the so-called type 1 mutations are the most common and the type 2 are the second most common; slightly different. Functionally they may have slightly different effects, although I think as a class, these calreticulin patients have more similarities than they do differences.

But there has been some literature to suggest that overall, calreticulin mutations are felt to be associated with a more favorable prognosis, at least compared to patients whoa re JAK2 mutant or perhaps triple negative. But specifically those that have the type 1 calreticulin mutation, the data is strongest that they have the most favorable prognosis. So based on that, you could say – the simplest thing is to say if you’re calreticulin mutant, you have a more favorable prognosis.

But perhaps the more nuanced is that that is particularly so for those that have the type 1 calreticulin mutation. In Marsha’s case it’s interesting, and to me a little bit of a paradox in that type 2 calreticulin mutations are, relatively speaking, more common in ET than they are in myelofibrosis.

So in that sense it’s perhaps not surprising that she has the type 2 calreticulin mutation. But overall, of course, ET has a more favorable prognosis than MF so it’s a little, in that way, a bit of a paradox. And the other way to look at this, and this has certainly happened for myself and I’m sure it happens with Dr. Moliterno is these patients with ET or myelofibrosis who were diagnosed many years prior, before calreticulin testing became available, you then tested for the mutation and confirm they were calreticulin once that test became available.

It’s one of those sort of: well, I just confirmed what I already knew which is that they had a more indirect course over these many years.

Andrew Schorr: It’s just amazing. Fortunately we can talk about this, and hopefully the word better prognosis sounds ] great.

So I, with primary myelofibrosis diagnosed with the JAK2V617F gene, Dr. Moliterno. But when you talk about prognosis, now you’re introducing medicines that we haven’t had that long; like for me. I’ve been on ruxolitinib now four and a half years and it’s been working. So how do we – when you talk about prognosis related to genes, though, that relates to what treatments you have, right?

Dr. Alison Moliterno: Right. We have a lot of work because these genes do have meaning; what version you have, and they’re going to have meanings in terms of prognosis but hopefully also we’ll start to gain information about really how you respond to therapy. So far, it seems that it doesn’t matter too much whether you have JAK2 or CALR mutation in response for  ruxolitinib.

But I think as we extend or molecular profiling, maybe we will learn that some lesions are less responsive or less favorably responsive to have some of these agents, and might be more responsive to agents that we have in the future. So I think we have to use this information both diagnostically, prognostically, and also just kind of monitoring our treatment expectations to some of these new agents.

Andrew Schorr: Right, it’s a moving target and I know you have a few things in trials. So just to tie the knot on testing, Dr. Oh; somebody wrote in and said: look, my doctor doesn’t require genetic tests. Where do I start and how do I ask for it? Because we’re hearing the two of you saying it’s pretty standard for you to get a clear picture of what the situation is. So is, how shall I say it, self advocacy related to testing today for an MPN patient important?

Dr. Stephen Oh: I think it definitely is. These diseases, while they’re not super rare, they’re not as common as hypertension or whatnot. When you go to a hematologist or oncologist who does not see very many of these types of patients, they might not be TransDigm on the testing that’s available. And so from that standpoint, I think certainly self advocacy is important. This has been emphasized already but getting to an MPN specialist is important.

If we’re talking about in the workup stage, it’s just sort of imagine different scenarios. There certainly could be a situation where the physician, whether they’re an MPN specialist or a more general hematologist or oncologist; they may not feel there’s a testing and that could certainly be the case.

[00:54:02]

But if there is a strong suspicion of a possible MPN, then I think there’s no question this kind of testing should be done. Even in the situation I’ve encountered with some patients where the insurance may require preauthorization, if you go through that it’s almost never rejected.

Andrew Schorr: Dr. Moliterno, here’s a question we got in from Jane. Jane writes: my understanding is that JAK2 is an acquired genetic mutation, and you both spoke about that; not inherited so we’re clear on that. Is it known what variables cause this mutation? I got the impression from what Steve said, no. But then she asks; can this gene expression be reversed?

Dr. Alison Moliterno: Right. First, why did this happen. I always joke with my patients; I tend to think MPN patients tend to be the most highly educated, intelligent, beautiful and have healthy lifestyles; why would they get this? MPN or not, disease is a lifestyle or other processes that we can sort of point to. I think in terms of if we just focus on JAK2V617F, that’s an acquired mutation in the bone marrow stem cell, but we’ve come to learn that this is a fairly common mistake, acquiring this mutation.

So if you look at my bone marrow stem cells, you can find evidence that this occurs frequently as a mistake; almost like a typing error that we all make on our keyboards, and that this happens at a fairly high rate. Most of the time as Dr. Oh mentioned, it is deleted or it’s in a cell that doesn’t have a long lived lifespan so it really doesn’t propagate in the bone marrow.

 Some fascinating studies looking at the cause of this; what are the factors? So, this Danish study looked at 43,000 individuals that participated in a healthy Danish lifestyle activity. They said they had stored DNA samples from blood. These were well people; they did not have myleoproliferative disease. But they found that they could detect the JAK2 mutation, V617F in a reasonable percentage of these well individuals, and that this was more prevalent the older they got. So that over 80, I think it was .2 percent of individuals actually tested positive for this. They were able to look back and show that yes, most of these people didn’t have an MPN, although some of them did have higher blood counts.

When they followed them, some of them did go on to develop MPN. But the point of that is wow, this is a common, natural occurrence and it most strongly associated with aging. Most MPN patients are in their mid 50s when they’re diagnosed; some very young and some are much older. So again, while gee, 50 isn’t that old, 50’s not that old. So again, there must be other factors that allow that to occur. And these large population studies, I think smoking has been an association; again maybe helps accelerate that mutation growing.

There’s host factors, and that maybe we have reasons that we will make that mistake more often; s genes that we have perhaps that we’ve inherited that influence how well we have integrity in our DNA. So that just gets a little to why did this occur.

Andrew Schorr: What about turning it back, though?

Dr. Alison Moliterno: Right, turning it back and I think this is another thing that is important. Again, when we think about surveillance, we do know there are some therapies that can specifically turn down or squash that clone and I think many of us have heard or even experienced patients who are on interferon, or pegasys, pegylated interferon. And we can see that if JAK2 disease can go into a hematologic remission and even molecular remission that the JAK2 clonal burden reduces and may even go to zero.

This has also been shown with CALR mutation positive individuals in small studies that perhaps we can suppress that. So we hope someday to – it’s still a little frustrating; not all patients have that benefit. It’s not clear which patients will go into these molecular remissions of turning it down.

But I think we will get there and we hope that JAK2 inhibitors would have that effect. I think the data still there are not pointing in that direction, but I think we will ultimately be able to actually target that clone and control how it expands and turn it back.

Andrew Schorr: So Stephen, take us into your labs and into the research that’s going on around the world. How fast is this changing now? Alison talked about 2005 with JAK2 discovery and you had CALR and some of these others. What’s the rate of change now?

Dr. Stephen Oh: I think there’s different perspectives you can look at this. For those of us that are doing laboratory research, we feel in the field that things have progressed quite rapidly.

To go from 2005 discovery of the JAK2 mutation to small molecule inhibitors going into patients I think within two years or less to this one drug being FDA approved a few days later; that pace of discovery and development has been quite rapid. The identification of the calreticulin mutation in addition to MPL, those are really landmark discoveries in this field.

For patients, I think the perspective might be that wow, I wish it could move faster and we kind of know as a class in general what JAK inhibitors do; can we move onto the next level, or next phase, or next class of treatments? And I think there is where my long term outlook is very optimistic, but in the short term we don’t really have that  kind of next candidate clearly identified as to what to do next after the JAK inhibitors.

Andrew Schorr: Dr. Moliterno, we always talk about clinical trials. This relates to the progress you all are trying to make. We’re your partners in that. As you do the testing and you say oh, now we see this gene, and we see this one and this one and we’re trying to figure out who’s the bad guy, or is this new one a factor that we’ve identified? So what would you say to us as we lived hopefully long term with these conditions about considering being in a clinical trial to help you make these discoveries?

Dr. Alison Moliterno: We have had great support from our patients, not only in participating but also helping design these trials or partnering with us. As Stephen said, these are rare diseases so we don’t have 50,000 individuals to test whether aspirin works or not like you can in a cardiology trial, and get that answer in a year and make a difference for individuals.

I would say that the trials now are going to be a lot more molecularly based. So instead of just disease, MF yes or now; these trials are now going to have the molecular profiling and response to therapy as part of their design. I think that will give us a lot more information overall than we’ve had in the past. So there’s many benefits to this molecular revolution.

One is understanding the cause of the disease, the other is monitoring it over time, and then response to trials which individuals respond to; which therapies. I think we’ve all seen the television ads about Keytruda and patients, as you mentioned early on with different solid tumors and particularly lung cancer, and how really the profile of that tumor needs to specific targeted therapy, and that’s what we want for MPN.

 Then now we’re even learning that it really doesn’t matter where a cancer may have started; if it’s in the kidney or in the lung, that again the molecular – the drivers of that indicate that you may respond regardless of what organ it started in; it’s really the lesion that you’ve got. And I think we will be bringing that to MPN patient trials.

Andrew Schorr: I’m involved in an initiative called Precision Medicine for Me, and it started in lung cancer but it is about this testing to see is there either existing therapies or investigation ones that line up. Or F dot now and as you know one of the major cancer medical societies called ASCO, American Society of Clinical Oncology.

The whole mission of the new president, a guy named Bruce Johnson from Dana Farber in Boston, a lung cancer specialist, is that these precision medicine approaches of each patient and their doctor knowing what are they dealing with at the molecular level to push that out throughout oncology; certainly in the U.S. if not worldwide. So I think we’re all in this together. Marsha, you’ve been listening patiently.

Now you’ve had this transition from ET many years, which Stephen was talking about we know often a very good prognosis. But then it changed, and a little scarier. I’ve already started that point, myelofibrosis. But when you hear this, how do you feel, just listening?

Marsha: I think when I was first diagnosed I was scared to death. But I think through education, I’ve learned to calm down and I just try to tell myself that this isn’t a sprint in my case, hopefully it’s going to be a marathon.

And until then, I’m just going to learn what I can do to help myself. I’m very curious about additional mutations; however my doctor said that really would not affect the treatment I would be currently undergoing. And the big thing, insurance, has come about. He’s very concerned about whether or not insurance would cover the cost and the value of it.

Andrew Schorr: Right. Stephen, is this – it sounds like maybe we’re making progress with insurance companies; that they want us to get a clearer picture with our doctor? What’s your take on that now?

Dr. Stephen Oh: The driver mutations, the JAK2, MPL< calreticulin testing, I think it should be and almost always is covered by insurance.

But when you get into the more extensive genetic testing, that’s where the insurance companies will often balk at covering it. Then it becomes somewhat problematic as to is this really worthwhile. Obviously that the costs for it and for any particular patient can vary in terms of what insurance will cover, what the copay is, and what they can reasonably afford. In general, while I do believe that there’s much utility to this kind of testing these days, if the cost is prohibitive I do not push it and I certainly do not think it’s mandatory.

Andrew Schorr: Dr. Moliterno, and I’ll mention to our audience we have a few more minutes; if you have a question and we haven’t covered it, please send in your question to MPN@patientpower.info, MPN@patientpower.info.

Dr. Moliterno, so we have the JAK inhibitor now, ruxolitinib. There are others that are being tested in various trials. As you look not just at the genes but at the treatments, are you fairly encouraged there that you will have a broader array to line up with people’s different situations, and also what the side effects of treatment, if somebody gets anemic or whatever their profile is?

Dr. Alison Moliterno: Yes, I am very optimistic. I think many of us, again if you look back at where we were five years ago in terms of the options that we have and where we assume we’re going to be in five years, hence I think there’s lots of room for application of these therapies, for combination therapies to use therapies together, even the ones that we have. So I’m very optimistic.

And I think I would say it is very anxiety-provoking to hear you need molecular profiling, and yet your doctor is saying we don’t really need that, or we’re concerned about the cost, which is certainly a concern. One thing I always say is that’s fine; the molecular profiling isn’t going to go away as an option, and the cost will come down in the next few years. We are now able to do things that we couldn’t even imagine we could do clinically in terms of looking at all aspects of genes, and this cost will come down.

So I would say to, for instance Marsha, yes we may not need it today but we can always get it in two years when things are different in terms of the availability of it and the interpretation of it. So again, I think it is reasonable to say your treatment is this, you’re responding well; happily we don’t need this at the moment.

I would agree with that, but I’m also certain that in three or four years, we won’t be having this discussion so much about the cost of this testing.

Andrew Schorr: Dr. Oh, here’s a question we got in. you’ve got to decipher this one for us. We have some really smart people out there, like PhDs. Is a germ line ASXL1 mutation a high risk or detrimental factor in the same way as a somatic mutation? So what’s germ line, what’s somatic, and is this germline ASLX1 mutation bad news, basically?

Dr. Stephen Oh: That’s a great question, and I think it also connects to a broader question. But to first answer you, talking about our acquired mutations which is the same thing as somatics; somatic means acquired.

If you’re talking about a germline mutation, in this case ASX01, it’s not the same thing as an acquired or somatic ASX01 mutation, which is what we’re generally referring to when we talk about that gene and its affect on prognosis. That also connects to the more broader point which is that the devil’s in the details.

Whether it’s ASX01 or another gene, the exact mutation may matter a lot in terms of what the significance you attribute to that. In many of the labs that do this type of testing, they will have a column for each mutation where they’ll make a call as to what they think it’s significance is, and they’ll say yes, pathogenic or it will say no pathogenic, or it will say uncertain. Part of that interpretation depends on whether it’s the germline or somatic AKA acquired mutation.

Oftentimes they can’t say for sure because the only way to determine that conclusively is to test tissue that’s not from the MPN. So, sometimes it’s uncertain as to even whether it is germline or somatic/acquired. So again, just to be clear on this particular question; if it’s thought to be a germline ASX01 mutation, it’s unlikely to be relevant or have a prognostic impact on that particular patient.

Andrew Schorr: So Dr. Moliterno, the other question you must get from people is do I have to worry about a family member? Because when they start talking about genes, you’re talking about what your hair color is, or hairline as I was joking with Stephen, or whatever characteristics herein are hereditary.

But then we’d say gee, is there a hereditary factor to an MPN?

Dr. Alison Moliterno: That is a very important question, and long before the JAK2 discovery, we realized that about 10 percent of individuals with an MPN will have a first or second degree relative with either an MPN or another cancer. So there does seem to be heritable factors at play here. Some of the interesting – and again, it’s not because you inherited – in your individual case you inherited the JAK2 mutation from the germline directly from Mom, but you inherited a risk of acquiring it.

We’re trying to understand that and again, what does it relate to; does it relate to germline variation in genes that allow this to occur, that allow you to get mutations in blood stem cells or in other tissues?

So yes, we are still working on that. It does seem to be a component of that. And that’s not unlike CLL, chronic lymphocytic leukemia also has sort of a familial –

Andrew Schorr: And I have that, too. I’ve got them both. I understand. So I think about that all the time. Marsha, you have children, don’t you?

Marsha: Yes, I have two children. But I think even more importantly, I have a cousin who has CML and another cousin who had stem cell transplant for AML. So I think that’s interesting.

Andrew Schorr: This is all in the hematology world, so Dr. Moliterno, do we have, Marcia or me, with two blood cancers? And I have three kids; what about this and is there a testing they should have, or how do we go forward?

Marsha: We don’t have – I would to recommend that they need a JAK2 test or specific MPN testing. If they have normal blood counts and they’re well, they don’t need to be evaluated for disease at the moment. The question is are there family genes that need to be elucidated, and if you have a lot of cancer in the family, so for instance families that have a lot of breast cancer, we often will send them for genetic counseling to understand what their particular risk is. And in breast cancer and some other cancers, we do understand some genes to test that can give us that information; familial genes. So far in the MPN, we don’t really have the knowledge of which genes are at play. 

Andrew Schorr: Dr. Oh, any comment on that because I’m sure you get the same questions. People say oh, my God, should I worry about family members?

Dr. Stephen Oh: Absolutely. It comes up pretty routinely and just to echo Dr. Moliterno, I generally do not recommend any special screening for family members, of those who have an MPN. I would also point out that even if there is, certainly it’s established that there is a slight increased risk for family members of patients with an MPN. Even if the risk was, let’s say, four fold higher for a first degree relative, the overall risk of developing MPN is so low that that overall risk for a family member is so unlikely that they’re going to develop an MPN.

Andrew Schorr:  Really? That gives some comfort; maybe you too, Marsha.

Marsha: Certainly.

Andrew Schorr: We’ve covered a lot of ground over the last hour, and I think on a very important topic now as mirroring the progress related to some treatments either approved or developing is, understanding our slice of an MPN, and the working with you on monitoring that and how does that relate to care. We have two noted experts with us who are helping propel this forward. So we’re your partners in helping that. Dr. Stephen Oh from Washington University and the Siteman Cancer Center, thanks for being with us once again and giving us of your time; I really appreciate it.

Dr. Stephen Oh: My pleasure.

Andrew Schorr: Okay, and Dr. Alison Moliterno, being back with us again from Johns Hopkins in Baltimore; thank you. Thanks for both of you; your very clear explanations, and Marsha Krone, we learned a lot, didn’t we Marsha?

Marsha: We sure did.

Andrew Schorr: Okay. Marsha’s my partner here; she’s done it twice and we’ll have you back sometime, Marsha.

Also, we should tell you Marsha is a very active preschool teacher so she has these little rug rats running around all the time, and thank God you have the energy to do that and I’m really glad you do, Marsha.

Marsha: Me, too.

Andrew Schorr: All the best to you. Well, this has been a wonderful program. We want to thank the Patient Empowerment Network for leading the way in this series, and Incyte Corporation for its support of this educational activity, and Patient Power our wonderful team Alan and Jamie who make it happen behind the scenes. We’ll be having more throughout the y ear. We welcome your questions; always send them to MPN@PatientPower.info.

And all of us moving forward living with an MPN, we’re going to live well and we have wonderful physician partners to help us do that as they understand the genetics and all those people working with them to develop therapies to help us live a long and strong life. Thanks for being with us in Carlsbad, California near San Diego.

I’m Andrew Schorr. Remember, knowledge can be the best medicine of all.
