Katherine:

We received an audience question prior to the program. They asked, “What does it mean to be refractory, and how is that different from relapsing?” 

Dr. Coombs:

I actually just had a conversation about this. I’m not sure that’s formally defined. I have heard one definition suggested is – I think everyone agrees refractory means you did not respond to your last therapy. That’s actually really bad. Most of our therapies work in almost everyone. So, refractory is a term that is generally accepted means no response. So, whatever therapy you’re on, the CLL did not get better, it got worse. That’s refractory.  

Another definition that I’ve heard based on this recent discussion is if you had a short remission duration, such as six months or shorter. Most of the therapies we use should work for quite a while, usually on the order of years. So, some people also consider refractory a short remission duration, six months or shorter.  

Relapse is probably the more common scenario. That’s a patient who has had some type of therapy, but they had a decent response, but that response wore off, more on a normal pace. Again, not on the order of months, but usually on the order of years.

Katherine:      

Let’s talk about if someone doesn’t respond to initial treatment or they relapse. Let’s start by defining some terms for the audience. What does it mean to be refractory?

Dr. Kline:       

So, refractory is a term that’s used to describe a situation where a person has received treatment but that treatment hasn’t worked as well as we have expected. And the most – probably the most important scenario is after initial treatment.

Most people, for example, who receive R-CHOP, somewhere between 80 and 85 percent will have a completely negative PET scan after treatment. That’s remission. If the PET scan is not negative and you do a biopsy and it shows that there’s still lymphoma there, that’s what’s called primary refractory. In other words, the person’s lymphoma was refractory to initial or primary treatment. And in clinical trials that are testing agents, drugs or immunotherapies in folks who’ve had multiple treatments, usually refractory is used to define someone who has either not responded or has had a very, very short response to whatever the last treatment they had was.

Katherine:                  

How does relapse then differ from refractory?

Dr. Kline:       

So, right, so relapse suggests that the lymphoma at some point was in a remission, right?

And so for example, a person gets six treatments of R-CHOP, has a PET scan at the end, the PET scan is clean. We say you’re in remission. Eight months later, the person develops a newly enlarged lymph node, and a biopsy shows that the lymphoma has come back, right? That’s what we would call a relapse. There was a period of remission, whereas refractory usually means there was never a period of remission to begin with.

Katherine:                  

Got it. How typical is it for a patient to relapse?

Dr. Kline:       

Well, again, if you look at all comers, if you treated 100 people with DLBCL, most, probably 70 to 75 percent, would go into remission. About 10 or 15 percent would have primary refractory disease and another 10 or 15 percent would have a remission that would end at some point and they would have a relapse. So, it’s not terribly common.

The problem is that once the lymphoma has either demonstrated that it’s refractory to treatment or it’s come back, it’s relapsed, it’s a little bit more difficult to cure the lymphoma at that point.

Katherine:      

How are patients treated then if they’ve relapsed or refractory?

Dr. Kline:       

Well, so for somebody who’s had primary refractory lymphoma or has a lymphoma that’s relapsed after initial therapy, again, say for the sake of argument with R-CHOP, for many, many years, the next line of treatment if you will was to administer what we call salvage chemotherapy, and this is different chemotherapy from the original R-CHOP, that’s meant to put the lymphoma back into remission. In other worse, to salvage a remission. And for folks whose lymphomas were sensitive or responded, shrunk down to that salvage chemotherapy, we would consolidate that remission.

We would make it deeper using high dose chemotherapy and an autologous or a cell, stem cell transplant. And that’s been the standard of care for younger patients for decades.

That paradigm has been challenged, particularly in refractory patients or those who have very early relapses after R-CHOP, by two important clinical trials that have demonstrated superiority of a type of immunotherapy, a cellular immunotherapy called CAR T-cell therapy, which seems to be more effective even than stem cell transplantation in that population of folks.

Transcript:

Katherine:                  

Before we move on to discuss the types of treatment, what are the goals of DLBCL treatment and how do they vary by patient.

Dr. Westin:                 

It’s a very important question to define at the outset what are we trying to accomplish when we’re talking about different treatments that we could recommend. DLBCL is a curable disease but, unfortunately, we don’t cure as many patients as we’d like. The majority of patients are cured but we always want to try and do better. But at the outset, we define our goals. And if somebody’s newly diagnosed, the goals of treatments is to try and go for a cure. That’s the end of that sentence when I am talking to my patient, that we are going for a cure, period. And then, we describe how we get there.

If somebody has relapsed or refractory disease, if the first treatments don’t work, usually we’re still trying to go for a cure, but there are some contexts where a curative treatment may be too toxic, the treatment itself may be a bad idea, just because of the potential of toxicities to be too much for a patient to tolerate.

So, there are situations, if the patients had a cancer that’s not gone away with the standard approach, sometimes we’re still going for a cure. Sometimes that may be difficult to achieve and we’d be going for a palliative treatment to try and prolong the patient’s quality of life and to try and give the patient more good days without harming them with treatments. But by and large, when we’re talking about the category or large B-cell lymphoma, the intention of treatment is to go for a cure.

Katherine:                  

How can patients make sure they understand their goals of treatment?

Dr. Westin:                 

It’s important to ask physicians, and PAs, and nurses at the outset about the goals of treatment. Sometimes we move quickly from diagnosis to treatment and don’t necessarily take a moment to talk about, “What are we trying to accomplish with this treatment?” We just see a fire and we’re trying to put it out. And the patient’s excited to get started after the scare of a diagnosis.

But I do think clarifying, “Can we talk a little bit about what the goal of this treatment is” – because sometimes there can be a mismatch between what a patient might expect a goal is and a physician, or a PA, or a nurse might expect a goal is. And if we’re not clarifying that and on the same page about that, sometimes there could be conflicts or confusion as we go into the treatments.

Katherine:                  

All right. I think we have a good understanding of treatment goals. So, when is it time to treat DLBCL?

Dr. Westin:                 

DLBCL is not a cancer that we wait to treat. This is a cancer that needs treatment very quickly after diagnosis. If a patient were not treated, the cancer would progress very rapidly. Some DLBCL’s progress faster than others but we would expect that if treatments were not administered, if we lived a century ago when treatments didn’t really exist, people would live, at the most, a few months with this cancer. This is a rapidly growing cancer that would result in death if we didn’t take care of it.

So, the time to initiate treatment is basically after a biopsy is obtained, the pathologist says, “This is large B-cell lymphoma,” a meeting with and oncologist occurs that says we got to start a treatment. Than then, ASAP after that to get going. What we know from DLBCL patients in the past is those that require treatment sooner – meaning you get a biopsy on a Monday and by Friday night you’re sick and you need treatment now or else – that tends to go along with a more aggressive version of DLBCL and perhaps can be associated with worse outcomes.

Patients who get a biopsy and four weeks later then they’re in the oncologist’s office talking about, “Maybe we should start a treatment,” but no symptoms, no problems, that usually goes along with a better prognosis. The so-called diagnosis to treatment interval can be actually powerfully prognostic.

Katherine Banwell:

What are the main factors that you take into consideration before a treatment approach is decided on?

Dr. Shah:

We always have to remember that treating a patient is also treating a person. So, it’s not just about what the disease the patient has but who the patient is. And so, we take into consideration goals that the patient as well as other health factors that may take – be taken into consideration. For example, the patient may have high blood pressure or a heart condition. But regarding the disease, we really also take into consideration what the profile of the disease is, maybe how much disease burden the patient has and some genetic factors that may impact our decision-making.

Katherine Banwell:

What is the patient’s role in treatment decisions?

Dr. Shah:

The patient should always be the center of the decision-making. I think that’s a really important thing for us to remember because ultimately, it’s the patient who has to make the decision and has to withstand the treatment. Alongside of that there may be some caregivers as well, but the patient has to, 1.) understand the disease, and 2.) understand the treatment options. So, it’s best if the patient has as much information as possible.

Katherine Banwell:

Are treatment considerations different for patients with relapsed disease?

Dr. Shah:

For patients with relapsed disease, there’s a lot of things to consider that may not have been true when the patient was first diagnosed. For example, you always have to think of what maybe the patient had as a prior – excuse me, as a prior treatment, and also how the patient tolerated it.

Katherine Banwell:

Why should a patient consider participating in a clinical trial?

Dr. Shah:

I am a huge fan of clinical trials, as you probably figured out. And the reason for that is that it’s the only way we know how to do things. And for everything we figured out about myeloma, it’s because patients participated beforehand in clinical trials. So, of course, it’s a way to pay it forward. But aside from that, there’s an experience that a patient can have on a clinical trial that is really unlike other experiences that patients may have. For example, they will be given the opportunity to understand a lot about their disease that maybe they may not have understood before, and they may have the opportunity to try a treatment that might be beneficial.

There are no guarantees in a clinical trial, and that informed consent procedure where the doctor tells you about the risks, benefits, and alternatives, should be very comprehensive and clear. But it does allow for patients to get access to something they may not have had before. And I think one of the other things that’s important is that it’s sort of a concierge service, I would say, with clinical trials, because you have to be monitored very closely. So, of course, all your symptoms have to be known. And you get a little bit more time, I would say, when you participate in a clinical trial because we really want to know the pluses and minuses of these treatments.

Katherine Banwell:

How can patients participate in research? Where do they start?

Dr. Shah:

Participating in research is a great opportunity for patients and something that we’re grateful for as myeloma physicians. There are many ways to look on various websites. There are things like SparkCures. There’s ClinicalTrials.gov. You can look at any academic website. Almost all advocacy groups also have opportunities for you to look at clinical trials.

And any time you get the opportunity to look at patient education sites, they may have a link for you to look for other clinical trials that might be relevant to your particular stage in disease or the particular kind of myeloma that you have. When in doubt, please, if you have a chance, talk to your local oncologist perhaps to maybe refer you to a myeloma specialist. We can do this by Zoom now, so there should be no reason that we can’t be a part of your care team at least for a consultation.

Katherine:

What advice do you have for patients when it comes to asking for appropriate testing and speaking up in their own care?

Dr. Carraway:            

This is so important. I think patients are leery to stir the pot or be difficult. I think coming from a place of inquiry, teach me about this, that, or the other thing, help me understand this, that, or the other thing – I would like you to show me why this decision or talk with me about why this decision versus another decision might be better for me compared to somebody else.

I can’t underscore the importance of advocating for yourself and asking questions about why am I getting this drug? What are the side effects to this drug? What is my prognosis? What is different about my case versus somebody else’s situation? How do I best prepare myself in getting ready for the therapy that I’m about to go through?

Those are all important questions that patients should ask. They should certainly have people, if possible in their family be advocates for them. I welcome that, and I think that that’s a really important part of going through this type of therapy for any patient. Your physician should welcome having your involvement in that. Don’t be shy about that. It’s your health, and any investment in that the most important people in that is inclusive of you and your caregivers. They should be a welcome part of the team.

Would you define induction therapy and consolidation therapy and tell us what the differences are?

Dr. Carraway:            

For most patients that are diagnosed with an acute myeloid leukemia, over the last 30 to 40 years we’ve used an intensive chemotherapy regimen that we call induction. Induction means that we’re trying to get the leukemia into remission with an intensive chemotherapy regimen. Classically, that has been two agents; one, a cytarabine based regimen along with an anthracycline, either idarubicin, danorubicin, or some anthracycline that’s similar.

Now, the cytarabine based therapy is a continuous infusion over seven days. The anthracycline is given over three days as an intravenous IV push, and so that’s why it’s kind of been nicknamed seven and three – seven days of cytarabine and three days of another anthracycline.

Now, that has constituted the induction intensive regimen in the hospital with the idea that that leukemia gets under control and goes away. More recently for patients, they can receive therapy that is not this inpatient, in-hospital, induction chemotherapy but rather use oral therapy combining with venetoclax, which is a Bcl-2 inhibitor, along with azacitidine, which is either IV or subcutaneous given to patients over seven days. The oral, venetoclax is every day.

That type of induction can also be given and is now an outpatient regimen and more often offered to patients that are older, over the age of 75.

That, too can be considered induction with the idea that once a patient is diagnosed with leukemia this regimen is started, and after one month or even two months on venetoclax plus azacitidine patients’ leukemia can get into what we call remission, where the blast percentages are less than 5 percent. Then, normal hematopoiesis of platelets being greater than 100,000 and a neutrophil count greater than 500 or 1,000, and the patient is then transfusion-independent.

In general, induction chemotherapy is that first round of chemotherapy that’s trying to get the leukemia under control.

Consolidation chemotherapy is when you use subsequent cycles of chemotherapy to keep the leukemia under control because we know that if we don’t continue to give some continuation of therapy that the small, little seeds of leukemia will re-emerge and leukemia will relapse.
