Can AML Be Cured?

Transcript:

Patricia:                         

Dr. Altman, let’s talk a little bit right now about treatments that are currently available for AML. What kinds of things might patients want to familiarize themselves with?

Dr. Jessica Altman:    

So, we are at a point in AML therapy where there’s not just one choice of treatment.

There are a number of choices that depend on patient characteristics, disease characteristics, and patient goals. So, there’s a lot that the physician with their patient and family members take into account and consider when they’re coming up with a therapeutic strategy.

Patricia:          

So, give us a couple of examples. Chemotherapy is one way to treat AML, correct?

Dr. Jessica Altman:    

Correct. So, the treatments all stem from a chemotherapy backbone. And there are more intensive chemotherapy regimens that usually involve a long, in-patient hospitalization and less intensive chemotherapy regimens. Those chemotherapy regimens can sometimes be combined with targeted therapy based on the genomic structure or the mutations present in leukemia cells. 

Patricia:          

Stem cell transplant is also an option as well?

Dr. Jessica Altman:                

Stem cell transplant is an option that is utilized ideally after the leukemia is in remission as a way of maintaining disease control.

And for some patients, that is the best approach for a curative option, and some patients’ leukemia does not require a stem cell transplant.

Patricia:          

Clinical trials available as well for AML, doctor?

Dr. Jessica Altman:    

So, we feel very strongly that the best treatment strategy for most patients is a well-designed, appropriate clinical trial for all phases of AML therapy. It’s because of research and clinical trials over the last number of years that we have had advances and more approvals for the treatments of Acute Myeloid Leukemia.

Patricia:     

So, when you’re talking with your patients, what kind of things are you considering when determining how to best treat AML?

Dr. Jessica Altman:    

So, that’s a great question. This is something that is the basis for the entire conversation that I have with my patients and their family members. 

I consider patient goals and patient fitness, other medical conditions, and a lot about the biology of the leukemia. If someone has an acute leukemia that is expected to be highly sensitive to intensive chemotherapy, then that is something that we want to think about. Versus if the patient has a disease that is not expected to be as sensitive to intensive chemotherapy, we frequently like to consider other alternatives in that space.

Patricia:     

So, in terms of options, as a patient what kind of things should I be thinking about when I’m working with you as my doctor about what the best treatment for me might be going forward?

Dr. Jessica Altman:    

So, I think the goal of the initial meetings and the initial consultation between a patient and their healthcare provider is to explore those things. We take a detailed history, understanding patients’ other medical issues. In addition to that, the social history and patients’ goals are very important, as things are not always a yes or no.  

They’re not dichotomous choices. And to be able to understand a patient’s goals, and for the healthcare provider to be able to explain what the intent of treatment is helps both parties come to the right decision for that individual patient.

Predictive (Familial) Genetic Testing vs. Cancer Genetic Testing: What’s the Difference?

Transcript:

Cytogenetics would be the term that I would say patients are unaware of and don’t understand it quite often. It’s probably the first time you hear it when you come and sit down and we talk about the disease because the first thing you want to know is what is my prognosis and what is the treatment. Well, a lot of that is made through the cytogenetics of the disease.

We use these terms and we don’t often explain what all of that means. And what that means is that the disease itself has chromosomes, has mutations, has genetic information that will help us determine which treatment is a better option for you or is there a genetic mutation that you perhaps have that we now have medications that are used to treat that genetic mutation as a said just a few seconds ago. Like for the three, if you have that mutation, we now have medication to treat that where we didn’t have that five years ago or even four years ago.

 So, that terminology of cytogenetic and biomarkers are very new. They’re not something that the general public knows or understands very well.

But when you come to academic centers like where I’m at right now that is all we’re going to talk to you about because we want to do personalized medicine. And personalized medicine means what is it that your disease looks like because your disease does not look like the other AML patients. Your disease is your disease and it looks different and it’s going to behave differently. And so, we want to know about those mutations. So, so much of your treatment, so much of the prognosis is so closely linked to that that I think it’s an important thing to know. It’s important to understand it. It’s important to ask. It’s important to pause your doctor and your nurses and say, “I don’t understand what you mean by that. What does that word mean? Can you explain that to me?”

Key Genetic Testing After an AML Diagnosis

Transcript:

Dr. Pinkal Desai:         

So for patients who are undergoing molecular testing or any diagnosis of AML, both cytogenetics and molecular profiling are important, so they do not supersede each other. This is the conglomerate information that we need from the diagnosis to make important medical decisions. Usually the diagnosis would include: looking at the cells under the microscope by the pathologist; flow cytometry, which is a way to identify the subtype of leukemia; chromosomes or karyotypic analysis, which is to look at the individual chromosomes and whether they are abnormal in these leukemia cells; and the last one would be the molecular mutations, which would be single-gene profiling of the leukemia cells.

All of these are important, and it’s not that one can be omitted. They’re all part and parcel of the diagnosis of AML, and all of them should be done.  

So my advice to patients whenever this topic comes up of molecular mutations is always an unequivocal – there should be no question that this should not be done. The advice is plain and simple. This has to be done at diagnosis and, in certain cases, at relapse as well in order to figure out the best treatment possible. If they’re at a site or a clinic where this molecular testing is not available, then they should seek a second opinion to a site that would do this testing because in this day and age of leukemia, there is no treatment and diagnosis that can be done without all of these components in place.

In the old days, we didn’t have a lot of treatment in AML. It was either chemotherapy or hypomethylating agents, and that’s it. But now we have several drugs, five or six of them, that were just approved in the past two years specifically for leukemia and targeting some of these mutations. We have Midostaurin, Gilteritinib, Ivosidenib, Enasidenib, and I don’t want to go on and on about these drugs, but the most important thing is that in this day and age where you have so many drugs, how to incorporate these drugs into the management for patients, both upfront and in the relapse setting, it’s extremely relevant to do this testing, and this is highly encouraged and should be done as part of the diagnosis and treatment.

Dr. Pinkal Desai:         

So we at Weill Cornell are a big leukemia center, and we are leading a lot of the clinical trials in AML, both in the upfront and the relapse setting. There are several research initiatives that we are highly interested in. One of them is how to incorporate some of these targeted treatments, both in the upfront and in the relapse setting.

The most important one that we’re actively working on is to monitor these patients, so MRD testing, or minimal residual testing, is extremely relevant in order to figure out whether the treatments are working in the right fashion, and would you change treatment or would it impact the patient’s overall survival if some of these mutations persist or not.

And we are really interested in monitoring these patients and these mutations to figure out a plan which is targeted not only for the mutation but also for the specific patient, and that is one of the things that we are very interested in and doing at Cornell.

We’re also looking at pre-disease mutations. There are several mutations – this is personally my research interest as well – there are certain people who are at risk of developing leukemia; for example, people who are undergoing chemotherapy for other cancers, and the presence of some of these mutations before the diagnosis of leukemia would highly be relevant because if we’re monitoring some of these people and figuring out who can develop this leukemia and can you do something about it, so this is sort of more on the prevention aspect of leukemia or secondary leukemia, which is also something we are interested in at Cornell and ongoing research is for us.

But the most important things is obviously for patients who actually have the diagnosis of AML, the best available agents as part of clinical trials, the best way to monitor them and design treatments so that we can achieve the best possible results for the patient is what we are striving for at Cornell, and it would be extremely helpful for patients to enroll into these trials and contribute both to their own treatment outcomes and also to the AML community at large.

Key Genetic Testing after an AML Diagnosis

Transcript:

Dr. Pinkal Desai:         

So there are several genes that we look for, but the most important ones from a standpoint of choosing treatments and monitoring, the first one would be FLT3. There are two kinds of FLT3 mutations, ITD and TKD; both can have different drugs that target them.

This is relevant because some of the upfront management, even when we choose – in younger patients, for example, when we are choosing chemotherapy, there are approved FLT3 agents that can be added to the chemotherapy. For example, Midostaurin, that’s a FLT3 inhibitor; we use that, and it’s important to know the FLT3 results, and preferably within 48 hours from the diagnosis, in order to choose the right treatment.

The other mutations that are relevant are IDH1 and IDH2. Both of them have approved targeted treatment against them, so depending on the clinical scenario of the patient, whether it’s new diagnosis or a relapse, these mutations are important to test, and the same for FLT3 as well.

I want to clarify here that sometimes the molecular mutations are absolutely important at diagnosis, but some of these mutations are also important to be retested in people who have relapsed because it’s not always the case that what is present at baseline may be the same at the time of relapse.

It’s possible that the clone is different, so some of these targeted mutations against which we have drugs, like FLT3, IDH, we need to test these mutations at relapse to make sure that we’re not missing them, particularly if they were present at diagnosis. The other mutation that is also relevant is TP53 because there are ongoing clinical trials that are targeting against these mutations, so the relevance of mutations are not only important in approved agents, but also in the ongoing clinical trials that are targeting these mutations.

 NPM1 is the other important mutation that is important in risk profiling, as well as monitoring over time to see if we can anticipate relapse or do something about it in the future.

There’s a laundry list of other mutations, but these are – I don’t think that patients should get lost into the individual mutations at the beginning. I think the relevant point here is that all of these need to be sent, and once the panel comes back with all of these mutations, then it’s time to sit down and go through, “Okay, the patient has FLT3, NPM1, plus some other mutation. What does that mean for me?” I think that’s what the patients should be asking. “Okay, I got these three mutations. I have these four mutations. Tell me how this is going to impact my care and my chances of survival?” I think that’s the most important thing.

Everybody’s leukemia is different. It’s more than a mixed bag; it’s actually unique to patients. Someone’s profile and genetic signature is different than someone else’s.

It’s important that every mutation is actually dealt with in relation to the other because it’s not just the presence of individual mutations, but the combinations of all of these mutations that are high relevant in figuring out whether this is important in the future or not.

 What Causes a Gene Mutation?

What Causes a Gene Mutation?

Transcript:

Dr. Pinkal Desai:         

So the reason that genetic testing is important and the patient should go through genetic testing after a diagnosis of AML, there are several reasons, actually, and we’ll go one by one. But before I go there, I want to clarify that genetic testing in AML does not mean that we’re testing for whether the patient inherits this mutation or genetic abnormality.

This is actually a mutation or genetic damage in the leukemia cells and not in the patient’s body elsewhere, so it’s important; this is a tumor-defining test and not meant to actually figure out whether this is inherited or not because most AML is actually not inherited. The other part that I want to focus on is that this testing, genetic testing or molecular testing or molecular profiling of leukemia, as we call it, is different than cytogenetics. Sometimes patients can be a little bit confused between what is molecular profiling and what is cytogenetics. Cytogenetics are big DNA or big changes in the chromosomes, while molecular mutations are single point gene mutations, which requires a much more detailed analysis of the leukemia cells.

The reasons that this testing is important, and the other part of it is that it’s just not after; it’s actually during the whole process of diagnosis of AML. If AML is suspected, then it should be done on the diagnosis bone marrow at the time when we’re drawing the blood. Otherwise, many times patients have to repeat a bone marrow biopsy to get this testing. So if something is already suspected that we are gonna maybe find leukemia, this should be done at the time of diagnosis. The first reason, which is the most important, is that when we do this molecular testing there’s a set of genes that we test. It’s 200s, 300s; every panel is a little bit different, but generally have the best components that we care about in the AML diagnosis.

There are targeted treatments against some of these mutations, and it’s important to know these mutations before the treatment begins. Not all mutations will change the way the treatment is designed, but there are certain mutations like FLT3, IDH, where it might matter as to what you choose as the frontline or the first line treatment, so it’s important that we actually get these results, at least some of these results, by the time we decide to choose the right treatment for the patient.

The second reason this is relevant is when patients go through AML induction or the first line treatment, the goal of which is induce remission, once they are in remission, the work is not done. There are several other things that we have to do and more treatments that are designed based on this molecular testing.

For example, depending on the molecular testing and the cytogenetics or the chromosomes, we profile patients as low risk, intermediate risk, or high risk. This risk means what is the likelihood that this leukemia will come back in the future, and how would that impact the patient’s survival? Some of the post-remission treatments are designed to change depending on the results of these mutations, so it’s important to actually know this at diagnosis because then the patients would go into remission, and yet we have to make a decision on what kind of best treatment to give post-remission in order to make sure that the patient is cured, or we maximize the chance of cure in this patient.

So the kind of chemotherapy, whether to transplant or not transplant, all of this is dependent on the molecular mutations. The third reason, which is becoming more and more relevant now in AML, is some of these mutations can be monitored over time.  

 It’s a much detailed testing to know the kind of remission or the extent of remission that they patient achieves, and you can actually follow these mutations over time, even in remission, to know that – is the molecular mutation zero, is it 0.2%? This is a very upcoming field in AML, and the idea of monitoring these mutations is relevant because if you have a mutation, can you do something about it post-remission? Would that alter some of the treatments? Would that help us anticipate if a relapse is coming before the actual clinical relapse happens and the blood counts go abnormal? Can we anticipate is this patient likely to relapse, for example, six months later, and could you prevent these relapses?

These are all the reasons why these genetic testing or molecular profiling of leukemia is highly relevant in the field of leukemia. We all cannot even make a decision anymore without having this full panel.

Key Genetic Testing after an AML Diagnosis

Transcript:

Acute myeloid leukemia, or AML, is a complex cancer that begins in the bone marrow.

Not all AML patients have the same disease. AML has many subtypes and understanding YOUR individual disease and subtype is key to accessing personalized therapy.

How can you learn more about your AML?

Genetic tests can provide more detail about your specific AML

These tests use laboratory approaches to identify changes in chromosomes, genes or proteins. A gene mutation is an abnormal change in a gene’s DNA sequence.

The results of genetic tests can inform your prognosis and treatment options.

The types of genetic tests that physicians use for patients with AML include:

  • Cytogenetic Analysis (or Karyotyping)
  • Fluorescence in situ Hybridization also known as a FISH test
  • Molecular Testing, which includes:
    • Polymerase chain reaction – PCR for short
    • DNA sequencing;
    • and Next-generation sequencing

Your healthcare team can help decide which test is best for you.

Genetic test results are used to identify genetic mutations that determine your specific AML subtype and help your healthcare team to better understand your prognosis, treatment path and assess how well therapy is working.

Once you have your results, there a number of targeted therapies currently available for AML.

Targeted therapies block the growth of cancer by interfering with specific molecules involved in the progression and spread of cancer. 

Targeted therapies include a class of treatment called “Inhibitors.”   AML Inhibitor therapies that target a genetic mutation include FLT3 Inhibitors and IDH Inhibitors.

Novel inhibitor therapies that are used across all mutational subtypes of AML include BCL-2 inhibitors and hedgehog inhibitors

Research is moving quickly in this field as new treatments are being studied to target genetic mutations in AML and other diseases.

How can you take action?

First, make sure you seek the opinion of an AML specialist. Discuss which tests you should undergo and review the results with your doctor. Educate yourself by doing some of your own research on the findings then collaborate with your healthcare team to determine a personalized treatment plan for your AML.  Finally, follow-up with your doctor regularly to understand when you should be re-tested.

Transcript:

Ross:

How easy is it to diagnose AML?

Dr. Pollyea:           

Well, I mean, I think there’s very clear diagnostic criteria for AML. But I guess that doesn’t really answer the question. And we certainly have patients who come to us after many months of frustration without a clear diagnosis.

So, those scenarios can play out. Many times AML’s a very dramatic presentation, so people get very, very sick very, very quickly with extraordinarily high white blood cell counts and suppression of all the other blood counts that come from the bone marrow like red blood cells and platelets.

In those cases it’s pretty clear that there is a type of acute leukemia going on. There can be some difficulty distinguishing Acute Myeloid from Acute Lymphoblastic Leukemia; those are sort of like cousins, but very different and treated differently. So, it kinda runs the gamut. I mean, it can be pretty clear, but it’s sometimes missed, so yeah.

Ross:

This is a great lead-in to my next question, which is about the symptoms of AML. What should be the warning signs that this might be something you need to get looked at?

Dr. Pollyea:                 

Right. So, at presentation, the main symptoms are reflective of the fact that the bone marrow, the organ that makes all the cells of the blood, has failed.

So, that can cause severe anemia. Signs of anemia: a white sort of appearance, feeling dizzy or lightheaded when standing, short of breath, weak, tired, fatigue. Those are all pretty clear presenting symptoms for AML. Because the bone marrow also is responsible for making platelets that clot the blood, some people will present with a bleeding complication, or a very subtle rash made up of these particular red dots. We call that a petechial rash. And that rash can come on when the platelet count gets very low.

Sometimes a person will present with an infection or infections that don’t go away or don’t clear because of decrease in white blood cells, the infection-fighting cells of the bone marrow. Those are made in the bone marrow and can fail in the setting of this disease. So, those are the most common symptoms at presentation, symptoms that are reflective of bone marrow failure.

Ross:

You mentioned that sometimes the presentation could be very dramatic, and it sounds like the symptoms are very severe, very quickly. Is that always the case? Is that often the case?

Dr. Pollyea: 

That is the case in, I would say, a minority of times. That’s usually the case. It’s more often seen in younger patients with AML. Typically, older patients with AML have a more smoldering course and a much less dramatic presentation, although this sort of very dramatic and dangerous presentation can happen in older patients, but it’s probably something like a third of the time that those very dramatic and medical emergency presentations occur.

Ross:                          

How important is early diagnosis?

Dr. Pollyea:                 

Well, I mean, it’s crucial. I mean, in particular in those cases where it’s a very dramatic and proliferative diagnosis, or presentation. A quick diagnosis and recognition of this condition is very important because the sooner a person starts effective treatment the better the ultimate outcome is.

I would say in general terms that applies to all AML patients, but certainly there’s some degrees of variation. So, there’s some AML patients that when I hear about their case on the phone from a referring doctor, it’s appropriate to see them next week in the clinic.

So, it’s not always a medical emergency, but we would never, even in those next-week-in-the-clinic patients, this isn’t something that can wait for weeks or certainly months. This is something that needs to be addressed fairly quickly.

Second Opinions in AML: The Importance of Moving Swiftly

 

Transcript:

Ross:

Dr. Pollyea, let’s start out with the basics. What are the causes of AML?

Dr. Pollyea:    

So, Acute Myeloid Leukemia, it’s a disease, a cancer of the bone marrow.

And it’s the result of an accumulation of mutation and chromosomal abnormalities that affect the DNA of a precursor cell in the bone marrow, otherwise known as a stem cell.

And those abnormalities accumulate until that cell can no longer properly mature, and it also can’t properly die. And so, a cell like that just makes copy after copy after copy of a cell until it crowds out the whole bone marrow with these sorta useless, immature cells.

And the end result of that is the failure of the bone marrow, which causes all of the problems associated with this disease. So, biologically, that’s sort of what happens to make this disease occur.

Ross:                                          

What are some of the myths that you hear from patients that come in and they say, “Oh, this must’ve caused my AML,” but you have to tell them that’s not so?

Dr. Pollyea:                           

Right. So, I mean, this is one of the most frustrating issues for patients and their families after diagnosis. I mean, it’s a rare disease, only about 30,000 cases a year in the United States. And so, trying to associate a rare disease with external or environmental factors is difficult to impossible. So, although there are a variety of exposures that probably contribute to this disease, we have very little understanding of what those exposures typically are or how that all works.

So, there’s a few things that we know pretty well; large doses of radiation, either associated with like industrial accidents like the Chernobyl disaster, or some of the radiation therapies that patients receive for other types of cancer. Other types of chemotherapy that are used to cure other cancers can contribute to this disease in later years.

We know that there are certain precursor conditions that can evolve to AML, so a person with myelodysplastic syndrome, for instance, has a fairly high chance of someday evolving to develop Acute Myeloid Leukemia. But beyond these sort of a few associations, there isn’t a whole lot that’s known or proven.

Ross:                                          

Now there is radiation associated with X-rays, and some people think that X-rays can cause AML. Is that true?

Dr. Pollyea:                           

So, I mean, I think a priori no because millions of people get X-rays every day, and only 30,000 people a year get AML. So, clearly it’s not a simple association between getting an X-ray and developing AML. But I think that there is an unknown interaction between environmental exposures and a person’s individual genetic makeup that makes a person more or less susceptible to developing something like AML with respect to exposure to the environment or X-rays and things.

So, while you cannot say that getting an X-ray will lead to AML, certainly there are some people who are more sensitive to the damage that’s done by something like an X-ray. And so, the best course of action is to be cautious and judicious about your exposure to these things, but not to not get these things when they are medically necessary.

So, that’s the challenging balance.

Ross:                                          

Here’s something else we’ve heard, that weed killers can be a risk factor for AML. Is that true?

Dr. Pollyea:                           

I mean, I think there’s a lot coming out now about weed killers and their association with other types of cancers. Again, I go back to the limitation we have in that in only 30,000 people a year in the United States get AML. Millions of people are exposed to weed killers.

We’re statistically never going to be able to make a clear association. I think that there are certainly some risks for some people. Whether you’re that person who’s more susceptible to developing leukemia or any other cancer because of exposure to a weed killer is impossible to know.

So, like all of these things, I think the advice we have is you have to live your life. You have to do your best to sort of avoid things that you can avoid that you think would be… Or that may cause problems. But not to let those things prevent you from living a normal life.

I know that’s not a satisfying answer, but at the moment that’s the best answer we have.

Ross:                                          

And, Dr. Pollyea, someone asked if benzene can be a risk factor for AML. 

Dr. Pollyea:                           

Yeah. So, benzene is one of the sort of rare environmental exposure associations that we do have clear associations with AML.

But the level of benzene that a person would need to be exposed to is really something that hasn’t been seen in this country in a very long time.

We’d be talking about like an industrial accident type exposure in almost all cases, so being exposed to a cleaning solution or some other fairly minor exposure to benzene, we don’t think is enough, in most cases, to prompt this disease. But benzene in very high doses, like an industrial accident, yes, that is something that we understand can certainly contribute or cause AML.

Ross:                                          

Autoimmune diseases, such as arthritis, can they increase the risk of AML?

Dr. Pollyea:                           

Oh, boy. That is a really interesting one. So, there are papers in the literature that do support those associations. And I know in my own practice I certainly see that trend. So, I do think that there is something there. There is a proven association between autoimmune conditions and myelodysplastic syndrome, which I said before can be a clear precursor condition to AML. So, certainly, that is an association that is a possibility.

It can be a little difficult to tease out whether it’s those diseases that are associated with ultimately developing AML, or the treatments that people get for some of those autoimmune diseases. Those treatments can modulate the immune system in certain ways that may, in fact, contribute or drive the disease. So, that’s a difficult thing to tease out.

But in general terms, yes, I think there are some associations. Now not by a long shot everyone with an autoimmune disease gets AML. It’s a teeny, tiny fraction. But I think there is an association there.

Ross:                                          

Is formaldehyde exposure another risk factor for AML?

Dr. Pollyea:                           

Yeah. We think that it is, and kind of along the lines of benzene. But, again, we think that those studies that have shown those types of association show it in very high amounts, amounts that most people in this country would not be exposed to. But I do think, or we do think that there is something to that, to formaldehyde somehow contributing to this.               

Ross:                                          

What’s the difference between a risk factor for AML and a cause of AML?

Dr. Pollyea

Yeah. So, I think risk factors by definition are things that may contribute to AML. And a risk factor for AML by that definition could be walking down the street and having some exposure to radiation from the sun. A cause of AML is something that is a much more solid sort of well-understood factor.

Like I said before, having myelodysplastic syndrome, there is a high chance that that can evolve to Acute Myeloid Leukemia. And if that happens then the MDS, the myelodysplastic syndrome, could be considered or would be considered the cause of your AML. So, very, very different in terms of the amount of evidence that goes into making those determination.

You’ve mentioned gene mutations. What mutates a gene? What causes that to happen that could lead down the line to AML? 

Dr. Pollyea:                 

That’s a great question. Most of the time we do not know the answer to that. These gene mutations occur spontaneously, randomly, and we don’t understand why they happen when they do happen.

And I know that’s, again, not a satisfying answer. It’s very frustrating, particularly patients come in, and, “I’ve lived a healthy lifestyle. I’ve done everything right. I exercise. I eat right. How could this have happened?”

These are things that for the most part are out of the control of a person. These aren’t impacted by your diet or your activity levels, what you eat or don’t eat, what you do or don’t do. That’s a real frustration. In the end, in almost all cases we don’t know or understand why these gene mutations or these, I call them mistakes in the body, occur when they occur. We don’t understand them.

Dr. Pollyea:

So, this is a disease of the genome. So, I mean, in a lot of respects it is a genetic disease. But the question is very different when you ask is this an inherited genetic disease? Is this disease due to a gene that I inherited from a parent or could pass along to a child?

For many, many years, the answer from the medical community was, “No.” This was not considered to be a disease that clustered in families or that could be inherited. We now know that that’s not necessarily the case. There are some very rare cases where this does seem to travel in families or cluster in families. And we’re now beginning to understand who those people are and what those genes are.

But the vast majority of people with this disease d  id not inherit a gene to contribute to it and cannot pass this along to a child. This is a random, spontaneous event that occurred within one person’s own body and is not traveling within family. So, we’re learning more and more about this, but really, the vast majority of this is not an inherited genetic condition.

You know, when you find out something like this, your tendency might be to jump on the web and start searching for AML. How do you vet those sources that you look at? How do you figure out that their – what would be a sign that they’re bogus sources?

 

Dr. Pollyea:                 

Yeah. I mean, I think this field is so rapidly changing and the treatment that we have, that I would, for the most part, assume that what you’re finding on the web is not relevant and is not an up-to-date resource. So, the resources that I listed, the NCCN, UpToDate, the Leukemia & Lymphoma Society, I should mention.

A very important resource that has up-to-date information, and they have even phone numbers for patients and their families to call to get connected with the proper people in a particular city, so that is a really important resource. But I’d be really, really cautious about what you find on the internet because things are changing so fast in this field. There’s a lot of outdated and misinformation on the internet.

 

Ross:                          

Well, then there’s outright scams. One of the things you mentioned before we went on is be cautious if someone’s asking you to put money upfront, or if it’s a nonmedical facility. What are some things that people should watch out for?

 

Dr. Pollyea:                 

Yeah. So, one of the things that is so important in our area is clinical trials and participating in clinical trials. Patients who opt to do this and receive experimental therapies can sometimes get the treatment of the future, get a drug that’s not currently available through the FDA, but may have a lot of promise.

And this is the way that we fight this disease. We’ve recently had an onslaught of approvals for AML and that’s because the patients being willing to participate in sanctioned clinical trials. So, participating in a sanctioned clinical trial is crucial, and it’s always a recommendation of all leukemia doctors.

When you participate in a conventional clinical trial, you’re asked to sign a consent form that explains what you’re doing and why. There is a confirmation that this has been vetted by an institution’s regulatory board that is prioritizing the safety and well-being of you, the patient. This has been approved by the FDA as a clinical trial. Nobody would ever ask you to pay money. That’s not ethical to participate in a clinical trial. Insurance covers whatever standard of care. And the clinical trial covers anything that isn’t.

So, if you find yourself in a situation where you’re not being asked to sign a consent form, where a clinical trial has not been reviewed by a regulatory board, where your doctor is not a leukemia specialist, where the FDA has not sanctioned the treatment, all of those are alarm signs.

Because there are people out there that are preying on patients in a desperate situation, a very difficult time in their life, and giving them sort of false hope and leading them down paths that are not legitimate.

One easy thing to do to sort of check to see if a clinical trial is legitimate is to go onto clinicaltrials.gov.

This is a resource set up by our national healthcare system that now feeds in every legitimate clinical trial from all over the world, needs to be registered on clinicaltrials.gov. So, if you can’t find your clinical trial on clinicaltrials.gov, I would have a lot skepticism and caution about that.

Dr. Elizabeth Bowhay-Carnes:

When doctors or people within the medical community use a term called personalized medicine, specifically we’re talking about some advanced testing that can be done on a patient’s DNA. Usually, this is talking about a specialized test that is called next-generation sequencing, and that particular test, next generation sequencing, is a technology that allows us to look deeper into a particular patient’s DNA or problems within the DNA of the cancer cell.

We then try to pick treatment options that match that patient’s particular problems with the DNA of their cancer cell. So, you will sometimes hear this particular technology referred to as personalized medicine, and usually we’re talking about next generation sequencing.
