Help us understand when it’s time to treat. Certain patients, as you said, don’t really need treatment right away because they’re asymptomatic. So, which patient type should begin to get treatment?

Dr. Castillo:               

That’s really the most important aspect of the discussion, I would say, because from my perspective – you know, I’ve been doing this for almost a decade, seeing probably 3,000, 4,000 patients with Waldenstrom’s in my career, I think one of the most important decisions is when to treat.

A number of our patients will be asymptomatic, and they will remain asymptomatic for years. So, really, treatment initiation in this scenario is not reasonable. Number one, we don’t cure the disease. Number two, patient have a long survival. I’m talking about 15, 20 years of survival in a large proportion of patients. So, a treatment that is going to last a year is not going to change a 20-year survival, so we don’t extend the survival of our patients in most cases.

Katherine:                  

Right. If a patient has been on watch and wait, how do you know when it’s time to begin therapy?

Dr. Castillo:               

Yeah, so essentially, when we see patients in whom we decide to monitor, right, watch and wait, which is monitor them, we follow them over time, and we see them sometimes every three months or every six months, and we get bloodwork.

We do bloodwork on those patients to look at the hemoglobin, just to see if there’s anemia or not, to look at the IgM to see if it gets too high or not. And if the IgM is too high, sometimes, we’ll have the patients have eye examinations on a yearly basis to make sure that there’s no changes in the vessels in the back of their eyes, in their retinas. That’s an indication of hyperviscosity. And every time we see them, not only do we look at the numbers, which I think is important, but we also look at the symptoms.

So, I classically ask my patients, “How’s your energy level, how well you’re doing, still able to do everything you want to do? Any numbness in your feet? Right? Any nosebleeds, any headaches, any blurred vision, right? Any lumps? So, I just go over this list of different symptoms that patients can experience. Are you having fevers? Are you having night sweats? Are you losing weight for no reason? Right? So, it’s a monitoring process.

Just to clarify further, for example, a patient can come to see me with anemia, and I know that Waldenstrom’s causes anemia, as I said before. But it is my duty as a doctor to make sure that there’s no other reason why the patient might be anemic. So, even though in the scenario, which is very likely that the disease is causing this problem, I still need to make sure that it is not something else driving this anemia for the patient, and then the anemia is severe enough. You know, some patients say, “Yeah, I’m a little tired, but I’m still able to do everything I want to do.”

So, really that’s a very minor process. And there are people who tell me, “You know what, I cannot play with my children anymore, right, because I’m so tired,” then that’s a different process. So, the severity of the symptom and how related to the disease it is, that combination is what really tells us who needs to be treated or not.

So, what I would say in terms of treatment timing for Waldenstrom’s patients, it’s not that you need treatment and then you don’t need it, and then you need it. It’s not like that. It’s more like you don’t need it; you don’t need it; and then it is reasonable to treat. And there is a period in which it’s reasonable to treat, and that period can last sometimes months to years. Some patients can decide to be treated a little earlier in the process with less symptoms. And some patients can decide to be treated a little bit later with more symptoms.

So, it has to do a lot with the patients, how they feel, how they’re tolerating the symptoms, how dangerous or potentially threatening those symptoms are. And that’s a conversation that it needs to take place between the doctor and the patient, understanding the patient’s preferences.

Katherine:                  

Let’s start with the very basic. What is Waldenstrom macroglobulinemia?

Dr. Castillo:               

Yeah, Waldenstrom’s macro – it’s a mouthful.

Katherine:                  

It is.

Dr. Castillo:               

I can just call it WM for ease.

It is a blood cancer, and in this blood cancer, the malignant cells are nesting in the bone marrow. And not only that. These malignant cells kind of secrete, produce, a protein called IgM.

IgM is an antibody that should be protecting us from infections, and in a normal state, we all have a little bit of IgM, and that’s a good thing. But in these patients, with these malignant cells, as these cells accumulate in the marrow, they actually increase the levels of IgM in our patients, and that can translate into a number of different symptoms, which we will probably talk about later.

Katherine:                  

Yes. How is it staged?

Dr. Castillo:               

So, the staging is a very interesting aspect. So, when we think about cancer, we think about stage I is in one spot, stage II in another spot, stage III, right, and it gets more extensive as we go along. That doesn’t really apply to Waldenstrom’s. Waldenstrom’s is a whole-body disease right from the start. The main reason for that is because it’s a disease of the bone marrow, and we all have bone marrow in all our bones, from our skull all the way to the great toe, so if you were to get a sample from each bone space, we would find the malignant cells there. So, this is a disease that is a whole-body disease right from the start, so therefore, there’s no stage I, II, or III. That is just the way we envision this.

Katherine:                  

How does the condition progress?

Dr. Castillo:               

So, it’s interesting because a number of the patients that we see in my clinic are actually asymptomatic at the time of the presentation. I would say maybe about a third of the patients I see in my clinic that were diagnosed with this disease for other reasons. They either had an abnormal laboratory value or an abnormal imaging study or some other reason. And when they come, they are worked up. Initially, they are found to have these malignant cells and these IgM elevation, but they have no other problems whatsoever.

So, I would say most patients will be asymptomatic at the beginning of the disease, and probably they will be asymptomatic for years before the symptoms actually do start. So, what happens is the malignant cells start taking over the bone marrow space, and it reaches a point in which the bone marrow, the healthy bone marrow, doesn’t have space to produce the normal cells that they should produce.

So, the first things that we tend to see in these patients is anemia, so the hemoglobin level starts dropping.

The red cells are the first ones that are being affected by this process so that the anemia is being seen first. If we leave that for a long time, then the other blood cells will decrease also, the white blood cells and the platelets over time. But the first one is almost always the anemia. And obviously, that, patients feel tired. They feel short of breath. They feel fatigued and all of that.

Now, the IgM itself can cause other problems on their own. If they have there’s too much IgM, they can actually make the blood a little thick, and that can cause a little bit of problems with the circulation, specifically in the eyes, for example. Some patients have blurred vision. Some patients have nosebleeds or headaches, right, with all that hyperviscosity, which means the blood is too thick. In some other patients, we have nerve damage. You know, they can have numbness in their toes, and then that increases into the – progresses, extends into the feet, into the shins, into the knees and then the fingers.

And so, that happens over years sometimes. Some patients can have enlargement of lymph nodes in their necks and in the axillary areas or in the inguinal areas, or even enlargement of organs, the spleen and liver and things like that. So, when we think about the clinical manifestations of Waldenstrom’s, it varies, very diverse. But I would say most patients would have anemia. I think that’s probably the most important aspect of it.
