So, Dr. Kahl, you also mentioned treatments and how oftentimes it’s not a cancer where you can just remove the cancer. Can you talk about some of the exciting developments with treatments and new innovative therapies, and what are the most important highlights for patients and families?

Dr. Brad Kahl:

Yeah. There’s a lot to talk about here. So I’ll start with how we approach a newly diagnosed patient, and then we’ll go into how we approach patients who have relapsed disease. So the most often, or the most common way a follicular lymphoma patient comes to medical attention is they just either notice a lump from an enlarging lymph node, or some enlarged lymph nodes are just found incidentally, because they’re having some testing for some other condition.

And so, like I said, very often patients don’t have symptoms. That’s very typical. Occasionally, the patients will have symptoms, and those symptoms might be pain from a large lymph node mass that’s pushing on something. Occasionally, they might have fevers or night sweats. They wake up in the middle of the night just drenching wet, or unexplained weight loss. Those would be symptoms that can occur in follicular lymphoma. But most patients who come to see us for the first time don’t have symptoms.

When we have a newly diagnosed patient and it takes a biopsy to make the diagnosis, we then need to do the staging evaluation. So that involves some sort of imaging. And nowadays that’s usually in the form of what’s called a PET scan, which gives us a good snapshot of the whole body. And it’ll show us enlarged lymph nodes. And then the PET portion of the scan will show us if the lymph nodes are metabolically more active.

So they show up as these bright spots on the PET scan. And that’s what allows us to stage the patient. It tells us where the disease is located and how much of the disease we see. And so I’m often telling patients, I don’t worry so much about the stage. I worry more about the disease burden. So the way I explain that to patients is, suppose I could take all the follicular lymphoma cells out of your body, and I made a pile. How big is the pile? And that’s actually, I think, more important than the stage in determining our initial strategy.

Because believe it or not, if we have a patient who comes to us with a new diagnosis of follicular lymphoma and they have no symptoms, and it turns out that their tumor burden is very low, we often will recommend an initial approach of no treatment, which is a strange thing for patients to hear. And we spend a lot of time trying to explain the rationale for that. So I’ll try to explain that to you now. Follicular lymphoma is hard to cure. So it’s this weird cancer in that it’s slow-moving. It often doesn’t make people sick, and we have good treatments for it, but curing it, like making it go away once and for all, proves to be kind of difficult.

And studies in the past have shown if you have a patient who has no symptoms and is low tumor burden, that their prognosis is just as good if you leave them alone at the beginning. And many patients will not need any treatment at all for two years, three years, five years. I even have follicular lymphoma patients who I’ve been observing for more than 10 years that have never needed any treatment.

About two out of every 10 patients that are newly diagnosed can go 10 years without needing any treatment. So that’s why we’ll start that strategy for some patients. And that psychologically can be difficult for patients. You’re telling me I’ve got a new cancer diagnosis. You’re saying you have good treatments for it. And yet you’re saying you don’t want to use any of those treatments. And so it takes a lot of talking and explaining to try to get people comfortable with that.

Some people never get comfortable with that, I admit it. But some people get very comfortable with it. But it is a very appropriate initial strategy for a low tumor burden asymptomatic person just to observe and get a handle on the pace of the disease. If the disease starts to grow, or if the patient starts to get symptoms, we can start our treatment at that time. And the treatment is going to work just as well as it would have had if we started it last year, or two years ago.

So we feel like we’re putting the patient in no harm, no risk of harm by starting on this strategy of a watch and wait. On the other hand, some patients have high tumor burden, they have a lot of disease, or they have symptoms. And for those patients we need to start them on treatment, because the treatment can put them in remission and get them feeling better. Right now, the most common frontline treatment in follicular lymphoma will be a combination of some chemotherapy and some immunotherapy.

The most commonly used regimen in the United States right now is a two drug regimen, a chemotherapy drug called bendamustine (Treanda), and an immunotherapy drug called rituximab (Rituxan). And you give that treatment every 28 days for six months. And it’ll put 90 percent of people into remission. And on average, those remissions last five-plus years. And it’s a very, very tolerable treatment. It’s not too bad as far as chemotherapy goes. There’s no, most people don’t lose their hair. They don’t get peripheral neuropathy that sometimes chemotherapy drugs give.

It’s not too bad for nausea and things like that. I’m not saying it’s easy or it’s fun. It’s none of that. But as far as chemo goes, it’s not too bad. And it’s effective, it is very effective. And I’ve given that treatment, and I have people who are still in their first remission 10 years later, so you can get, for some people can get these really long remissions.
