Abstract | Outcomes in patients with acute lymphoblastic leukemia (ALL) who experience relapse after allogeneic hematopoietic cell transplantation (HCT) are unsatisfactory. This study aimed to evaluate the outcomes of patients with ALL who underwent second HCT (HCT2) for relapse after first HCT. It was a single-center retrospective study including adult patients with ALL who underwent HCT2 between 1991 and 2020. The cohort was stratified according to the transplant year, and included 39 patients with a median age of 29 years. A more recent transplant year was associated with achievement of complete remission (CR) and use of reduced-intensity conditioning (RIC), compared with an earlier transplant year. The overall survival (OS) rate and 2-year cumulative incidence of non-relapse mortality (recent vs. earlier) were 55% vs. 8% (P < 0.001) and 26% vs. 75% (P < 0.001), respectively. In multivariate analysis, non-CR (vs. CR; HR 3.6, 95% CI 1.2-11.3, P = 0.025) and myeloablative conditioning (vs. RIC; HR 3.5, 95% CI 1.3-9.4, P = 0.011) were negative prognostic factors for OS. Outcomes of the recent cohort from real-world data are promising, and achieving CR and using the RIC regimen at HCT2 may be an important therapeutic strategy. |
