Pre-transplant consolidation chemotherapy may not improve outcomes after reduced intensity conditioning hematopoietic stem cell transplantation for acute myeloid leukemia in first complete remission

Abstract: The role consolidation chemotherapy prior to reduced-intensity (RIC) HCT is unclear. We reviewed 60 consecutive patients with AML in CR1 undergoing RIC HCT at the University of Minnesota and evaluated outcomes based on exposure to pre-transplant consolidation chemotherapy. The two year incidence of relapse and the probability of overall survival were similar between those who did and did not receive consolidation chemotherapy. The 2 year incidence of transplant-related mortality was slightly higher in those who did not receive consolidation and correlated with a higher HCT comorbidity index (HCT-CI) in that cohort. Our data suggest that exposure to consolidation chemotherapy prior to RIC HCT may not improve post-transplant outcomes for patients with AML in CR1. [Copyright &y& Elsevier]
