Background: Administration of anti-CD19 chimeric antigen receptor T-cell (CART19) immunotherapy for large B-cell lymphomas (LBCLs), a subset of non-Hodgkin lymphoma (NHL), involves high costs and access to specialized tertiary care centers. We investigated whether minority health populations (MHPs) have equal access to CART19 and whether their outcomes are similar to those of non-MHPs.
Methods: We analyzed the prevalence and clinical outcomes of patients treated with commercial CART19 at two geographically and socioeconomically different institutions: the Abramson Cancer Center (ACC, Philadelphia, Pennsylvania) and the Knight Cancer Institute (KCI, Portland, Oregon).
Results: In the ACC catchment area, 8956 patients were diagnosed with NHL between 2015 and 2019 (latest available data from the state registry), including 17.9% MHPs. In the ACC, between 2018 and 2022 (CART became available in 2018), 1492 patients with LBCL were treated, and 194 received CART19. The proportion of MHPs was 15.7% for the entire LBCL cohort but only 6.7% for the CART19 cohort. During the same time, in the KCI catchment area, 4568 patients were diagnosed with NHL, including 4.2% MHPs. In the KCI, 396 patients with LBCL were treated, and 47 received CART19. The proportion of MHPs was 6.6% for the entire LBCL cohort and 4.2% for the CART19 cohort. The 3-month response, survival, and toxicities after CART19 infusion showed similar results, although the number of patients who were treated was limited.
Conclusions: This study shows that the access of MHPs to tertiary centers for LBCL care was preserved but appeared reduced for commercial CART19 immunotherapy. Although clinical outcomes of MHPs seemed similar to those of non-MHPs, the small sample size precludes drawing firm conclusions. Further studies are needed.
