The impact of pretransplant minimal residual disease (MRD) on outcome of myeloablative cord blood transplant (CBT) for acute myeloid leukemia (AML) in complete remission (CR) has not been reported. Seventy-two AML patients were assessed for MRD before CBT, and the majority (84.7%) of these patients received single-unit CBT. All patients received intensified myeloablative conditioning with BUCY2 or TBICY plus high-dose cytarabine, and graft-versus-host disease (GVHD) prophylaxis consisted of cyclosporine and mycophenolate mofetil. The cumulative incidences of neutrophil and platelet engraftment, acute or chronic GVHD were comparable between MRD-negative and MRD-positive groups. The cumulative incidence of transplant-related mortality (TRM) and relapse did not differ significantly between the two cohorts (25.6% vs. 32.5%, 16.1% vs. 19.2%; p=0.52, 0.61). There were no apparent differences in 3-year overall survival (OS) (68.9% in MRD-negative group and 57.9% in MRD-positive group, p=0.31) and 3-year leukemia-free survival (LFS) (62.5% in MRD-negative group and 52.7% in MRD-positive group, p=0.42) between both groups. The current study suggests that AML patients in morphological CR1 or CR2 who have detectable MRD might benefit from unrelated CBT with intensified myeloablative conditioning.
