Abstract

Cord blood transplantation (CBT) is an alternative donor transplantation method and has the advantages of rapid availability and the possibility of inducing a more potent graft-versus-leukemia effect, leading to a lower relapse rate for patients with non-remission relapse and refractory acute myeloid leukemia (R/R AML). This study aimed to investigate the impact of CBT, compared to human leukocyte antigen-matched related donor transplantation (MRDT). This study included 2451 adult patients with non-remission R/R AML who received CBT (1738 patients) or MRDT (713 patients) between January 2009 and December 2018. Five-year progression-free survival (PFS) and the prognostic impact of CBT were evaluated using a propensity score (PS) matching analysis. After PS matching, the patient characteristics were well balanced between the groups. The five-year PFS was 25.2% (95% confidence interval [CI]: 21.2–29.5%) in the CBT group and 18.1% (95% CI: 14.5–22.0%) in the MRDT group (P = 0.009). The adjusted hazard ratio (HR) was 0.83 (95% CI: 0.69–1.00, P = 0.045); this was due to a more pronounced decrease in the relapse rate (HR: 0.78, 95% CI: 0.69–0.89, P < 0.001) than an increase in the NRM (1.42, 1.15–1.76, P = 0.001). In this population, CBT was associated with a better 5-year PFS than MRDT after allogeneic HSCT.
