ABSTRACT
We compared transplantation outcomes of adult patients with AML that underwent cord blood transplantation (CBT) in CR1 following 1 versus 2 induction courses. Study included 325 patients, 243 (75%) with 1 and 82 (25%) with 2 induction courses. Engraftment was lower for patients achieving CR1 after 1 vs. 2 induction courses 91% vs. 99% (p = 0.02). Incidence of acute GVHD was similar, 38% and 36% (p = 0.81), as was 2-year chronic GVHD at 23.4% and 27.5%, respectively (p = 0.65). Two-year non-relapse mortality (NRM), relapse incidence (RI), leukemia-free survival (LFS), overall survival (OS) and GVHD-free, relapse-free survival (GRFS) were not statistically different between patients achieving CR1 with 1 vs. 2 induction courses with 23% vs. 24% (p = 0.87), 25% vs. 30% (p = 0.4), 52% vs. 46% (p = 0.3), 59% vs. 50% (p = 0.2), and 44% vs. 41% (p = 0.66), respectively. Results were confirmed by multivariable analysis, NRM (hazard ratio (HR) = 1.1; 95% CI, 0.6-1.8, p = 0.7), RI (HR = 1.4; 95% CI, 0.9-2.3, p = 0.1), LFS (HR = 1.3; 95% CI, 0.9-1.8, p = 0.2), OS (HR = 1.3; 95% CI, 0.9-1.9, p = 0.1), and GRFS (HR = 1.1; 95% CI, 0.8-1.5, p = 0.5). Overall, outcomes of AML patients undergoing CBT in CR1 achieved after 1 or 2 induction courses are similar.
