HLA-mismatched MST vs HLA-matched NST for AML in Intermediate-risk
Acute Myeloid Leukemia
About this trial
This is an interventional treatment trial for Acute Myeloid Leukemia focused on measuring Acute Myeloid Leukemia, microtransplantationHLA-mismatched microtransplantation, nonmyeloablative stem cell transplantation, graft-versus-host disease

Active Comparator
MST(microtransplantation)
NST(nonmyeloablative transplantation)
The microtransplantation conditioning regimen included high-dose Ara-C chemotherapy (2.0 to 2.5 g/m2 per 12 hours intravenously on days -4 to -2) followed by an infusion of HLA mismatched stem cell 24 hours (day 0) after the completion of cytarabine.
The NST(nonmyeloablative transplantation)conditioning regimen consisted of 30 mg/m2/d fludarabine for days -6 to -2, 1.5-2 mg/kg/d anti-lymphocyte globulin for days -5 to -2, 40 mg/kg/d cyclophosphamide for days -4 and -2 and 2.0-3.0 g/m2/d cytarabine for days -6 to -4,followed by an infusion of HLA matched stem cell after the completion of regimen. The GVHD prophylaxis included cyclosporine A and mycophenolate mofetil
