Analyses of transplantation outcomes for adult patients with mixed-phenotype acute leukemia.

ABSTRACT: Mixed-phenotype acute leukemia (MPAL) is associated with poor prognosis. Although allogeneic hematopoietic stem cell transplantation (allo-HSCT) can achieve long-term survival, optimal transplantation strategies remain unclear. We analyzed a national registry of adult patients with MPAL who underwent allo-HSCT between 2008 and 2022 in Japan. Among 417 patients, median age at transplant was 44 years (interquartile range, 32-55); 61% were male, 20% were BCR::ABL1-positive, and 66% underwent transplant during the first complete remission (CR; CR1). At 5 years posttransplant, overall survival (OS) was 54%, disease-free survival was 49%, relapse was 28%, and nonrelapse mortality was 23%. Multivariate analysis identified older age (adjusted hazard ratio [aHR], 1.78 [95% confidence interva
