Optimal postremission therapy choice in this heterogeneous patient population is currently unsettled. In the current study, we compared outcomes in IRcyto AML recipients of autologous (autoSCT) (n = 312) or allogeneic stem cell transplantation (alloSCT) (n = 279) in first complete remission (CR1). Molecular risk was defined based on CEBPA, NPM1, and FLT3-ITD mutational status, per European LeukemiaNet 2017 criteria. Five-year overall survival (OS) in patients with favorable molecular risk (FRmol) was 62% (95% confidence interval [CI], 50-72) after autoSCT and 66% (95% CI, 41-83) after matched sibling donor (MSD) alloSCT (P = .68). For patients of intermediate molecular risk (IRmol), MSD alloSCT was associated with lower cumulative incidence of relapse (P PB Elsevier YR 2020 FD 2020-12-24 LK http://hdl.handle.net/10668/17556 UL http://hdl.handle.net/10668/17556 LA en NO Rodríguez-Arbolí E, Martínez-Cuadrón D, Rodríguez-Veiga R, Carrillo-Cruz E, Gil-Cortés C, Serrano-López J, et al.
