Objective To evaluate the efficacy and safety of HLA identical and haploidentical related allogeneic hematopoietic stem cell trans?plantation in the treatment of acute myeloid leukemia(AML)and myelodysplastic syndrome(MDS). Methods A total of 21 patients with AML and 8 patients with MDS who underwent allogeneic hematopoietic stem cell transplantation in our hospital from April 2011 to April 2016 were ana?lyzed retrospectively,including 16 cases of HLA?identical allogeneic HSCT,10 cases of haploidentical allogeneic HSCT,and 3 cases of syngeneic HSCT. BUCY2 or TBI plus CY ± chemotherapeutic agents was the regular conditioning regimen. No graft versus host disease(GVHD)prophylax?is was required for syngeneic HSCT,but cyclosporine in combination with methotraxate was essential for allogeneic HSCT,cyclosporine,methotrax?ate,antithymocyte globulin,mycophenolate mofetil and glucosteroids for haploidentical HSCT. Results All patients achieved fully donor?originat?ed hematopoiesis. Two patients died of severe acute GVHD within 100 days post HSCT. Acute GVHD with gradeⅡ?Ⅳoccurred in 23.1%(6/26) patients,chronic GVHD in 50%patients,therapy and relapse?relevant mortality was 4/29(13.8%)and 6/29(20.7%)cases within a median follow?up of 23(1?60)months,respectively. Two?year overall survival and leukemia free survival rates are 68.09%( 95%CI:45.77%?82.78%)and 60.22%(95%CI:38.19%?76.55%),respectively. High risk AML is still the main challenge to long?term leukemia free survival. Conclusion HLA identical and haploidentical allogeneic HSCT for AML and MDS is safe ,effective and feasible. Minimal residual disease monitoring and pre?ventative as well as preemptive intervention is necessary for improving prognosis of high risk AML.
