Haplo-identical HSCT
Drugs: Drug:Methotrexate 1g/m2 d1,IV (in the vein) , used in cycle 1,3,5 Drug:arabinoside 2-3g/m2,q12h, d2-3, IV, used in cycle 1,3,5 Drug:cyclophosphamide:300mg/m2 q12h, d1-3, IV,used in cycle 2,4,6 Drug:Epirubicin 60mg/m2.d,d4,used in cycle 2,4,6 Drug:Vindesin 4mg/d,d4,d11, IV,in cycle 2,4,6 Drug:dexamethasone 40mg/d,d1-4,d11-14, IV, in cycle 2,4,6 Drug:Methotrexate 20 mg/m2/w,po, during maintenance treatment for 2 years Drug:6-mercaptopurine 60 mg/m2/d,po,d1-d28,during maintenance treatment for 2 years Drug:Vindesin 4mg/d,Predisone:1mg/kg, d1-7, every month during maintenance treatment for 2 years
Haplo-identical HSCT Protocol:G, donor treatment with recombinant granulocyte colony-stimulating factor (rhG-CSF); I, intensified immunologic suppression; A, antihuman thymocyte immunoglobulin (ATG) for the prevention of GVHD; C, combination of peripheral blood stem cell transplantation (PBSCT), and bone marrow transplantation (BMT),named GIAC regimen. Graft versus-host disease(GVHD) prevention regimen: CSA/MMF/MTX, cyclosporine A(CSA) 1.25mg/kg/d, i.v administrated in two doses from day -109 until bowel function returned to normal, at which time patients receive oral CSA until 12months after HSCt and then gradually tapered. Every 12h, 0.5g mycophenolate mofetil (MMF)(0.25g for children) was administrated orally from day -10 to +30 and subsequently 0.25g from days +30 to +60. Methotrexate (MTX) was administrated at a dose of 15mg/m2 on day +1 and 10mg/m2 on days +3,+6, and +11.
