简要总结
This study aimed to evaluate the efficacy of reduced intensity conditioning (RIC) regimen in elderly or high comorbidity burden patients who receive haploidentical hematopoietic stem cell transplantation (haplo-HSCT). Haplo-HSCT is an effective treatment option for patients who did not have identical sibling donor (ISD) or unrelated donor (URD). However, post-transplant transplant-related mortality (TRM) is one of the major causes for transplant failure, and the risk of TRM for old patients or those with high comorbidity burden was higher. RIC regimen may decrease the risk of TRM for haplo-HSCT recipients. The study hypothesis: Using RIC haplo-HSCT regimen in elderly patients or those with high comorbidity burden can reduce TRM and improve survival.
详细描述
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.

研究组 & 干预措施
RIC regimen
Old patients or those have high comorbidity burden without identical sibling donor or unrelated donor would receive RIC haplo-HSCT.
RIC preconditioning regimen consisted of cytarabine (2 g/m2/day, days -10 to -9), busulfan (3.2 mg/kg/day on days -8 to -6), cyclophosphamide (1.0 g/m2/day, days -5 to -4), fludarabine (30 mg/m-2/day, days -6 to -2), semustine (250 mg/m-2, day -3), and rabbit antithymocyte globulin (thymoglobulin, 2.5 mg/kg/d, days -5 to -2; Sanofi, France).
干预措施: Cytarabine (Drug)
