RIC Regimen for Elderly or High Comorbidity Burden Patients Receiving Haplo-HSCT

RIC regimen was given for elderly patients or those with high comorbidity burden who would receive haplo-HSCT. The elderly patients were defined as older than 55 years. The burden of comorbidities in HSCT recipients was assessed based on the hematopoietic cell transplantation-specific comorbidity index (HCT-CI), and patients with score ≥3 were assigned as high burden. The primary end point was transplant-related mortality, and the secondary endpoints included overall survival, disease-free survival, relapse, engraftment, graft-versus-host disease (GVHD), and infections. Following time is 1 years.
