In this retrospective, multicenter study, we compared the outcomes for older AML patients (age 60每77 years) receiving allogeneic hematopoietic cell transplantation (alloHCT) (nˋ=ˋ431) with those treated on prospective National Clinical Trials Network induction and nontransplantation chemotherapy (CT) consolidation trials (nˋ=ˋ211). AlloHCT patients were younger (median age: 64.2 versus 67.9 years, pˋ<ˋ0.001), but more frequently had high-risk AML (high WBC, secondary AML, and unfavorable cytogenetics). Overall survival (OS) was worse in alloHCT during the first 9 months after CR1 (HRˋ=ˋ1.52, pˋ=ˋ0.02), but was significantly better thereafter (HRˋ=ˋ0.53, pˋ<ˋ0.0001) relative to CT. Treatment-related mortality (TRM) following HCT was worse in the first 9 months (HRˋ=ˋ2.8, 95% CI: 1.5每5.2, pˋ=ˋ0.0009), while post-HCT relapse was significantly less frequent beyond 9 months (HRˋ=ˋ0.42, 95% CI: 0.29每0.61, pˋ<ˋ0.0001). Despite higher early TRM, alloHCT recipients had superior long-term OS [29% (24每34%) versus CT 13.8% (9每21%) at 5 years]. Although this is a retrospective analysis with potential biases, it indicates that alloHCT led to heightened early risks from TRM, yet reduced relapse and superior long-term survival relative to CT in older AML patients in CR1 %U https://www.nature.com/articles/s41375-019-0477-x
