The survival of adult patients with standard-risk acute lymphoblastic leukemia(ALL) need to improve. We want to compare the efficacy of haplo-identical hematopoietic stem cell transplantation (HSCT) with chemotherapy for adult(age:18-39 years old) ALL patients in first phase of complete remission (CR1)
Although the high complete remission rate (80%-90%) can be achieved, the long-term survival rate of standard-risk adult patients with acute lymphoblastic leukemia(ALL) is only 25%-55% when they receive chemotherapy alone. The survival rate can be further improved uo to 50%-75% when they receive HLA-matched HSCT However, the chance of finding a HLA-matched donor is low, especially in China. Alternative donor such as halpo-identical related donor might be an choice. Our retrospective analysis showed about 59% overall survival could be achieved when standard-risk adult ALL patients received halpo-identical HSCT.Therefore, we start this randomization controlled trial to compare the efficacy of haplo-identical HSCT with chemotherapy for adult(age:18-39 years old) ALL patients in CR1.

Haplo-identical Protocol: myeloablative human leukocyte antigen (HLA) haploidentical stem cell transplantation (haplo-SCT) using pretransplant ATG and granulocyte colony-stimulating factor (G-CSF)-stimulated grafts (ATG+G-CSF) GVHD prevention regimen: CSA/MMF/MTX, 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 HRD-HSC and then gradually tapered. Every 12h, 0.5g MMF(0.25g for children) was administrated orally from day -10 to +30 and subsequently 0.25g from days +30 to +60. MTX was administrated at a dose of 15mg/m2 on day +1 and 10mg/m2 on days +3,+6, and +11.
Patients receive 6 cycles of consolidation chemotherapy after randomization, including Hyper-CVAD-B regimen-Hyper-CVAD-A regimen/Hyper-CVAD-B regimen/Hyper-CVAD-A regimen/Hyper-CVAD-B regimen/Hyper-CVAD-A regimen.Maintenance treatment includes MTX 20mg/m2/w，po，6-mercaptopurine 60 mg/m2/d，po，d1-d28，VP（VDS 4mg,d1, Prednisone 1mg/kg d1-7) every one month for 2 years.
