From 1999 to 2020, age-adjusted mortality rates for patients with ALL aged 55 and up didn’t change, oncologist-hematologist Jamie L. Koprivnikar, MD, of New Jersey’s Hackensack University Medical Center, reported at the annual meeting of the American Society of Hematology. The rates were 10.8 per 1 million in 1999 and 10.6 per 1 million in 2020.
By contrast, the mortality rates for children aged 0-15 improved from 3.5 per 1 million in 1999 to 2.2 per 1 million in 2020.
“The findings were particularly surprising and disappointing to me,” Dr. Koprivnikar said in an interview. “My overall sense is that we’ve really improved our outcomes of treating patients with ALL and are making great strides forward, moving away from so much chemotherapy and toward more kinds of immunotherapies and targeted therapies. So we need to understand what’s driving this.”
According to Dr. Koprivnikar, ALL is more common in children than adults. However, “even though the majority of cases tend to occur in children, we know that the majority of deaths are actually in the adult patient population,” she said.
One challenge for treatment is that therapies that work well in the pediatric population aren’t as effective in adults, she said. ALL is biologically different in adults in some ways, she added, and older patients may have more comorbidities. “It ends up being a really complicated story with all of these different factors playing into the complexity.”
For the new study, Dr. Koprivnikar and colleagues analyzed death certificate data from the Centers for Disease Control and Prevention’s Wide-Ranging Online Data for Epidemiologic Research database. They found that 17,238 people died from ALL between 1999 and 2020. There were no significant differences in terms of gender, race, and region.
The study authors noted that mortality rates didn’t change despite medical advances in ALL such as blinatumomab, inotuzumab, and targeted tyrosine kinase inhibitor-based therapy. It’s unclear if the treatments have made it to the older-adult setting yet, Dr. Koprivnikar said.
There may be problems with access due to socioeconomic factors as well, she said. “ALL is actually more common among those of Hispanic heritage, and we don’t completely understand that.”
Marlise R. Luskin, MD, a leukemia specialist at Dana-Farber Cancer Institute, Boston, said in an interview that the study “is a reminder that clinical trial outcomes are limited — specifically trial results that often emphasize early results and report on a select population of older patients who generally are socially resourced and physically and mentally more fit.”
Dr. Luskin added that the study reports on outcomes through 2020, including years when newer regimens were not broadly disseminated outside of clinical trials.
Moving forward, she said, “this report suggests we need to continue to develop novel approaches and understand long-term outcomes as well as ‘real world’ outcomes. A similar study should be repeated again in 3-5 years as novel regimens become standard. We hope to see improvements.”
No study funding was reported. Dr. Koprivnikar disclosed consulting relationships with Alexion, GSK, Novartis, and Apellis. Other authors reported no disclosures. Dr. Luskin disclosed ties with Pfizer, Novartis, Jazz, Kite, and AbbVie.
