Dr. John Sweetenham, of the UT Southwestern’s Harold C. Simmons Comprehensive Cancer Center, and Dr. Marc Braunstein, of NYU Langone Health, discuss key data from the CAPTIVATE and GRIFFIN trials and other compelling studies in hematologic malignancies featured at the 2022 ASCO Annual Meeting.
Dr. John Sweetenham: Hello. I'm John Sweetenham, the associate director for Clinical Affairs at UT Southwestern Harold C. Simmons Comprehensive Cancer Center and host of the ASCO Daily News podcast.
For my guest today, I'm pleased to introduce Dr. Marc Braunstein, a hematologist, and oncologist at NYU Perlmutter Cancer Center. We'll be discussing key posters on advances in hematologic malignancies that will be featured at the 2022 ASCO Annual Meeting.
Our full disclosures are available in the show notes and disclosures of all guests on the podcast can be found on our transcripts at asco.org/podcasts.
Marc, it's great to have you on the podcast today.
Dr. Marc Braunstein: Thank you, John. It’s a pleasure to be here.
Dr. John Sweetenham: So, Marc, there are going to be some very interesting abstracts with some provocative results presented at the ASCO Annual Meeting this year. I know we've selected a number of these to speak about today, beginning with Abstract 8027 on the subject of multiple myeloma. And this I think is a long-term follow-up study for long-term survivors of multiple myeloma more than 12 years out now. Can you comment on this and let us know what you believe the key takehomes from this study are?
Dr. Marc Braunstein: Sure. Absolutely, John. So, this was a prospective registry that has been in place since 2009, and it's composed of various practice settings, but primarily community practices where most patients get their myeloma care. And what they did was they looked at about 1,400 patients with newly diagnosed multiple myeloma across 250 sites in the U.S. between 2009 and 2011 who were included in the registry. The participants also filled out the quality-of-life surveys, and they compared a group of long-term survivors who had more than 8 years of follow-up to patients who were not long-term survivors below that 8-year threshold.
So, about 20% were in the long-term survival group and 80% in the non-long term survival group. And they basically characterized those 2 groups. What they found was that the individuals who did have long-term survival were generally younger—median age of 62 versus 68, and had better performance status, were more likely to receive stem cell transplants, about 66 versus 60%.
And therefore, the implication of this is that patients who fit those criteria may have a better prognosis in addition to the other cytogenetics and other factors we use as prognostic indicators. And what was also interesting was that the 8-year overall survival of the overall group was about 36%.
So, we still have room to go in terms of bringing new therapies to extend survival in this condition. And only 20% of the total population were long-term survivors at that 8-year threshold. So, those were the general findings of the abstract.
Dr. John Sweetenham: Do you think it gives us new information on patient selection for more intensive therapies upfront?
Dr. Marc Braunstein: Well, I think it certainly tells us which patients are more likely to have longer-term survival. I think we know in multiple myeloma that it's essential to really use the patient's presenting features, their disease features, their comorbidities, and their degree of fitness or frailty to guide how intensive a therapy or regimen we can devise for that individual patient. But I think it certainly says that if you have a patient who is on the younger side of the spectrum, who is eligible for stem cell transplant, who has a better performance status, those are the patients that are more likely to have the long-term survival. It doesn't necessarily say that if you're not in that category, you won't have long-term survival, but on average, those were the patients who fared better in the long term.
Dr. John Sweetenham: Okay. So, staying for a little while on the subject of multiple myeloma, Abstract 8037 is really addressing a very different question. It's the application of circulating tumor DNA analysis and its association with relapse in patients with refractory myeloma. Would you comment a little on this and maybe let us know what you think the significance of this will be for the future?
Dr. Marc Braunstein: Sure. My colleagues in the solid tumor space are using circulating tumor DNA regularly and in the myeloma field, we're a little bit jealous of them.
So, it's helpful to have a study like this that's lookin...
