DOI: 10.1016/j.thromres.2021.08.020The curative potential of hematopoietic stem cell transplantation (HSCT) is greatest in pediatric patients with relapsed or refractory B-cell acute lymphoblastic leukemia (B-ALL) is greatest when remission is achieved prior to transplant. Chimeric antigen receptor (CAR) T-cell therapy offers a novel path to remission for chemotherapy-refractory patients, most of whom subsequently undergo HSCT. While the toxicities of HSCT and CAR T-cell therapy are increasingly well-described, data on outcomes when both modalities are used sequentially remain limited. This single-center retrospective study aims to compare survival and transplant-related toxicity in pediatric patients with B-ALL who received CAR T therapy prior to HSCT versus those who did not. The hope is that we can identify patients at higher risk of transplant-related complications and intensify supportive care strategies for these patients during the HSCT process.
