The search for the optimal conditioning regimen before allogeneic hematopoietic stem cell transplantation (HCT) for acute myelogenous leukemia (AML) and myelodysplastic syndromes (MDS) has been ongoing for decades. In this issue, Solh et al present an original analysis evaluating the impact of conditioning intensity on different disease risk index (DRI) groups of patients with AML and MDS. An impressive difference was observed in outcomes between reduced-intensity conditioning and myeloablative conditioning (MAC) regimens in the low/intermediate-risk disease groups, supporting the use of MAC in this population. Further prospective trials in this population are encouraged.
