Katherine Banwell:

What are the indicators that a patient’s disease may have relapsed?  

Dr. Mark Schroeder:

Yeah, so we would typically be following a patient about every three months. Somebody that has gone through the initial induction, consolidation, maybe they’re on maintenance therapy, or maybe they’re on active therapy for after they have relapsed from a myeloma.  

Each of those visits every three months, we are monitoring bloodwork, we’re monitoring the monoclonal protein that the myeloma produces.  

Or if it doesn’t produce much of that protein, we’re monitoring other parameters, so urine testing or maybe even imaging like a PET scan. And we’re looking for consistent rises in that number, and we’re looking for, not necessarily a little rise in the protein, but incremental continuous rise – that suggests that the myeloma is starting to grow again, and it’s growing on the current treatment, and we need to switch gears and try a different treatment. There are some patients who – that protein, the myeloma or the myeloma cancer doesn’t die to treatments – that’s refractory. So, we try a treatment, and there’s just no response. We don’t see a drop in the protein in the blood, we still see a good burden of the myeloma in the bone marrow biopsy. And those patients, that’s also an indication to try a different treatment.  

Katherine Banwell:

You mentioned that myeloma often returns, so how typical is it for a patient to relapse? 

Dr. Mark Schroeder:

Yeah, I would say that’s the norm for patients with myeloma. There are reports in patients who undergo things like stem cell transplant, that maybe 10 percent of patients might be out 10 years without detection of their myeloma, but that’s not the norm. So, most patients who are diagnosed with myeloma will go through periods of treatment and hopefully periods of remission – the majority go into periods of remission to myeloma where it’s not very active, but the myeloma tends to come back. 

Katherine Banwell:

I think you’ve already answered this, but I’m going to ask you in case you give different or more information. If a person is relapsed or refractory, how are they typically treated? 

Dr. Mark Schroeder:

So, when they relapse, it depends on their prior treatment. So, if the myeloma is not responding to a drug, then it is, from the physician’s perspective that’s treating you, a good idea to change the type of chemotherapy drug that you’re on. Any time, whether it’s diagnosis or relapse, clinical trials are appropriate to engage with and potentially even use as primary treatment. All clinical studies in myeloma or for cancer in general are typically engineered around active treatments for the cancer. And so, those studies in myeloma when you’re having the cancer relapse, say, early in the course of your cancer, those studies typically are geared to use drugs that are approved by the FDA. Later in the lines of treatment, maybe you’ve had to progress after four lines of treatment, but trying to move them earlier, and they’re very active in the fourth line.  

So, you could potentially have access to an active treatment moved earlier in the treatment through a clinical trial. There is also a long list of other approved myeloma therapies. There is a good handout, I think, through the NCCN for patients for myeloma that lists a lot of the approved myeloma therapies and kind of guides patients. It’s a good resource book that I would point any of the listeners to.

Katherine Banwell:

I would imagine monitoring patients is different for each of the MPNs. So, how are patients typically monitored over time, and let’s start with essential thrombocythemia?  

Dr. Scandura:

Yeah. I think – again, it’s similar. You know, what’s near-term, what’s long-term? And so, in all of these diseases, thrombosis risk is a near-term risk. That’s something that I am monitoring in certain ways to help mitigate that risk. In ET and PV, I approach them similarly. Blood counts are certainly – these are diseases of the blood forming system. Certainly, monitoring blood counts I find helpful. But the reality of it is, in ET, there is not a clear linkage between blood counts and risks.  

And so, I like to keep the platelet count near normal if I can. But I also recognize that it may not be worth suppressing all of the blood counts to achieve that landmark, because it’s not clear that that’s really reducing the risk any more than just having somebody on a medication that helps control the blood counts. In polycythemia vera, different blood counts are very important. The red blood cells are kind of like part of the clotting risk. We know from clinical trials that keeping the red blood cell parameters within certain ranges reduces the risk of clotting. And so, what I monitor in polycythemia vera is the hematocrit. In women, I like to keep it below 42. In men, I like to keep it below 45.  

But I don’t just – I’m not a slave to the hematocrit. I am keeping an eye on the other blood counts and the other red blood cell parameters. So, for instance, what’s the size of the red blood cells? That tells me a little bit about what’s going on in the blood formation for that patient. And what’s the number of red blood cells? So, sometimes people can have very small red cells, because they’re a little iron-deficient and have a huge surplus of the number of red blood cells. And that tells me a little bit about how their blood forming system is responding to therapy.  

Iron deficiency in polycythemia vera is very prominent. I personally believe it’s a very major driver of symptoms in patients who are receiving phlebotomy as part of their care. And it’s something that I monitor and really counsel patients on. My goal is to make phlebotomy independent, but it can take a while.  

Everybody starts out iron-deficient, and then we take iron out of their body through blood with the phlebotomy. And that makes them more iron-deficient.  

Katherine:

Right. 

Dr. Scandura:

I monitor symptoms from patients, and sometimes that can tell me that their disease needs to be – their treatment needs to be tweaked a little bit, even something as simple as aspirin. People can sometimes have burning in the skin or itching that is sometimes responsive to changing the aspirin dose or how it’s given, once a day versus twice a day.  

And that simple thing can be a big change for a patient who’s kind of, literally, climbing out of their skin or wishing they could and to try and find something that is helping.   

I had a patient the other day. He had COVID. I said, “Oh, you should probably get this medication.” Do you have your primary care physician? Who’s taking care of you?” And he goes, “Well, to be honest with you, you’re my guy.” And so, it’s true. I see this patient a lot. And so, sometimes they forget. If I’m not paying attention to their blood pressure, the risks or treatment of diabetes, cholesterol, lipids, their screening programs for mammogram or colonoscopy, health maintenance issues, I do keep an eye on that in patients, because I do think it’s a part of the MPNs.  

I think that there are excess risks for patients for some of these factors. Certainly, if you think of it as three strikes, they get a strike for having an MPN. I don’t want them to have any other strikes. So, diabetes, hypertension, those are strikes that I can potentially, at least, treat or refer them to somebody to help comanage with me. And so, that’s kind of my general approach. 

Katherine:

What about patients who have myelofibrosis? Are they monitored more closely? 

Dr. Scandura:

Yeah, I think it depends a little bit on the patient. Patients with early myelofibrosis often don’t have any symptoms or near-term risks much different than those from ET or PV. As the disease can progress, then some of these patients have more profound problems with symptoms, which I may be trying to find a solution to make them feel better. And also, blood counts can become more of an issue.  

Transfusions in some patients who are very high white blood cell count, the spleen is often quite enlarged. Although, in my experience, most patients aren’t really bothered by the size of their spleen as the physicians are. But it is something where I think, on average, they’re monitored a little bit more closely to quite a bit more closely depending on the patient. 

Katherine:

What happens if someone suddenly has a change in blood counts? What do you do? 

Dr. Scandura:

Yeah. I mean, repeat it. That’s the first thing. Also, check what’s going on. It’s not uncommon in patients with MPNs that I’ll see them and the counts are a little bit out of whack, the white count is much higher than it’s been, and questioning them. “Oh, yeah. I had X, Y, or Z last week or the week before.” It used to be a upper respiratory tract infection, or they had a minor surgical procedure.  

And sometimes the responses to these things can be accentuated in patients with MPNs. And so, if that’s what of this story, I certainly would repeat it and let things calm down a little. And that’s often all it is. I’m much more of a monitor of the trends. So, one-time measure doesn’t generally excite me. It might make me want to have a follow-up a little more – in a shorter period of time. Of course, it depends on what the change is. But, for most of the changes that we observe, they’re relatively minor. And I will monitor them over time.  

If I see a trend where something is progressively increasing or decreasing over time, then I start thinking about what else is going on. And that’s always in the context of what’s going on with the patient. How are they feeling? What’s their physical exam like? What are the other laboratory values like?  

Katherine:

When is a bone marrow biopsy necessary? 

Dr. Scandura:

I would say a bone marrow biopsy is absolutely necessary at the time of diagnosis. I personally do not routinely monitor by bone marrow biopsy unless it’s part of a clinical trial.  

But I do perform a bone marrow or want to look at the bone marrow morphology if there is one of these changes or at least a trend that I want a little bit more information about. And so, if – or if it’s been a very long time since somebody has had a bone marrow. If it’s been five or ten years, then sometimes I may recommend we look just so we can collect a little bit more up-to-date information.  

But I don’t routinely do a bone marrow, but I will do it if there are laboratories that are kind of trending in the wrong direction, there’s symptoms, there’s physical findings that I’m just not sure about. And I think it would help me be more sure as to what’s going on and be able to discuss that with the patient. Sometimes, just to say, “Hey. Look, we were worried about this, but the bone marrow looks really good.”

Katherine Banwell:

“What complications can arise from an MPN during pregnancy?” 

Dr. Scandura:

Well, look, pregnancy – here you have two things, one of them common and complicated and the other one uncommon and complicated. So, common is pregnancy, but every pregnancy is different. And there’s a lot of changes going on in the body, and there’s certain risks that can go along with that as well. So, clotting risks sometimes can be increased in pregnancy. And then you have an MPN, where you have a clotting risk on top of that. The pregnancy really changes what kinds of medications we can think about using. And so, there are certain medications that we use comfortably in patients that would be an absolutely forbidden medication in a pregnant woman.  

And so, it depends a little bit on what’s going on with the patient. But, if they have a history of clotting, then certainly, we would think about wanting to control the blood counts. It depends a little bit on what the disease is how we would do that. Interferons are commonly used in pregnancy, and they are safe in pregnancy and can improve the outcomes in some patients with pregnancy.  

But short of that, in patients, for instance, who are very thrombotic risk, sometimes we have to sort of balance the risk of having a clot and something that can interfere with the pregnancy and the risk of bleeding. So, it’s not uncommon that people are on blood thinners during pregnancy at some point, but it really depends on the individual patient. What we do here is we keep very close contact with the patients.  

And all of our patients are seen by the high-risk OB/GYN. So, it’s not the general obstetrics people who are monitoring the patient, so they’re much more closely monitored for complications of pregnancy. And we are seeing them more frequently during pregnancy to help, from the MPN side, to try to optimize and minimize the risks of clot. And that doesn’t end as soon as the baby’s out. If breastfeeding, their clotting risk is not normalized after pregnancy, as soon as the baby comes out. And so, you know, there’s an adjustment for several months afterwards where we’re still kind  of thinking about this person a little bit differently than we would if they were not or had not been recently pregnant.

Katherine:

We’d be remiss if we didn’t bring up financial concerns, treatment and regular appointments can really become quite expensive. Understanding that everyone’s situation is different, of course, where can patients turn if they need resources for financial support? 

Dr. Scandura:

Yeah. It depends on what the issue is. So, one of the biggest areas that I found this can interfere with care is when we have copays that are really not reasonable and not affordable. And so, how do we fix that? How do we get access to an agent that might be beneficial for a patient but that – you know, and the insurance has approved it, but they’ve approved it with such a high copay that it’s just not an option anymore.  

And so, there are foundations. The PAN Foundation, we often will reach out to for copay assistance. And, actually, many companies have copay assistance programs for their individual drugs. And so, we have some of our nurses who are quite good at navigating these different agencies, and some of them are kind of drug-specific.  

And because we see a lot of patients with MPNs and the number of drugs is not that great, we’re pretty tapped into what are the options for copay assistance that might be helpful. And it often works. It doesn’t always work. I had a patient I saw pretty routinely, and I kind of like my certain group of labs that kind of make me feel like I have a good sense of what’s going on. But he was getting killed with the lab costs. And he mentioned this to me, and then I have to do what I tell my – I have three teenage daughters, right? And, when they were littler – smaller, younger, we spent a lot of time distinguishing needs from wants, right?  

So, this was one of those instances. What laboratory do I need to make sure that this patient is safe? What do I want because it makes me feel like I have a better idea of what’s going on? And maybe I can back off on those wants if I’m seeing the patient pretty frequently, which I happen to be at that time. And so, some of that is a conversation.   

And it depends on the specifics of the insurance and a little bit of back and forth and knowing how to kind of minimize that financial burden when that’s starting to compromise care.

Katherine:                        

Once a patient has started treatment, how do you know if it’s working?

Dr. Forsberg:              

So, we’re lucky in myeloma in that we have some pretty easily accessible tools to evaluate how our response is going. How the myeloma is responding to treatment. How we’re sustaining that response and if we may be losing it at some point in time. And a lot of those come down to those blood tests I mentioned before.

The tools that measure protein levels or antibody levels in the blood, whether that’s intact antibodies or fragments of antibodies. So, that is that serum protein electrophoresis or serum free light chain levels.

Sometimes in conjunction with urine collections, which can measure abnormal antibodies in the urine. Those are ways that we can monitor on a month-to-month basis, how well the myeloma is responding to treatment. How well we are sustaining in a response or remission status. Or if it might be starting to come back.

We do at times use those in conjunction with other tests that look at things like bones using X-rays, MRIs or higher resolution scans like a PET scan. Or things like bone marrow biopsies which we may do at specific time points to evaluate the myeloma in different ways.

Whether that’s to evaluate a remission and see how deep that response might be, correlating it with blood work. Or if the myeloma come back, making sure we understand the characteristics of it. So, we’re lucky to be able to draw on tools that are not very invasive using bloodwork and sometimes urine. But we may couple that at certain other points in time with more substantial evaluations as well.

Katherine:                  

What could indicate that it’s time to switch therapies?

Dr. Forsberg:              

So, the most common indicator may be a change in one of those tests that I just mentioned. If we notice that there’s an increasing level of an abnormal antibody in the blood, one that’s usually produced by the myeloma, that may be our first indicator that the myeloma has become more active and that we need to change our treatment approaches. Other times people may develop symptoms from the myeloma that shows that it is becoming active and those would be our indicators. So, those are different ways that we help to monitor the myeloma. One is assessing the bloodwork and other things that we monitor pretty closely.

The other is being vigilant for new problems that may come out. So, we end up spending a lot of time with folks over the years with the myeloma and some of that may feel a bit routine, but we’re always trying to make sure that we’re attentive to new issues as they come up.

Why You Should Consider a Clinical Trial for Lung Cancer Treatment

New and Improved Lung Cancer Treatment Options


Transcript:

Dr. Erin Schenk:

We have a very active clinical trial practice in the lung cancer world for one reason alone, and that’s that while our current therapies are good, we can still do better. Lung cancer accounts for significant cancer-related deaths in the United States and the world. And we wanna work to try and improve how well patients do and also improve how many patients we are able to cure. Clinical trials can be at any step of your workup or treatment.

So, even patients with earlier-stage disease meaning lung cancer where we can resect it with surgery, there are a number of clinical trials going on right now to try to better improve the outcomes we see with our normal standards of care. So, whether you are having a lung cancer removed by surgery whether you’re receiving chemotherapy and radiation and immunotherapy whether your lung cancer has happened to spread outside of the lungs, there are clinical trials available at every step in the game.

And I would really encourage you to ask your cancer care team or your doctor about whether or not clinical trials might be available in your area. Because often, they can help identify new targets or other ways of trying to attack the vulnerabilities of your lung cancer.

If you are considering a clinical trial, there are a number of important questions to find out from the clinical trial team as well as your cancer care team. Some of the things are really practical, logistical questions and one of those is, “How often do I need to come to clinic? How many more schedule visits do I need?”

Usually, with clinical trials, upfront so before you get on the clinical trial or once you start receiving the clinical trial medicine or therapy, often there are more frequent visits in that initial time period. But after things are – after you’ve had several treatments with the trial medicine, often it becomes more standard of care meaning visiting once every three weeks for blood work and a visit with your team and then infusion.

So, it’s often a little more work up front, and then it gets back to the usual expectations of how often you have to be in our offices. So, I think those logistical concerns are very real because especially for larger institutions, sometimes, coming to our campuses can be a bit of a challenge. So, that would be one. I would recommend discussing logistics. Discussing with your team as to why they think this would be a trial for you is important.

Occasionally, we are able to screen for certain markers or certain things that are expressed on the cancer cells and then match you with clinical trials that try to target those specific molecules or proteins or flags that are on the surface of the cancer cell. So, oftentimes, we try to match patients up to a specific clinical trial, so better understanding why that one was recommended. And then I would ask your team to also discuss what are the side effects that have been noticed.

Often with these clinical trial medicines, we don’t have a lot of experience with how well patients do on these therapies. But sometimes, we can give you an idea in terms of what we expect and what we will watch closely for. So, I think logistics are important, why your doctor or your cancer team thinks this is a good trial for you, and then finally, what sort of side effects have been noticed as best we can tell with this new trial medicine.
