Summary

This project is a prospective, single-center, randomized controlled clinical study. The subjects were high-risk or relapsed/refractory AML or ALL patients aged ≤ 65 years diagnosed by bone marrow cell morphology, immunology, genetics and therapeutic efficacy evaluation. The TmBU scheme or modified Bu/Cy (mBuCy) scheme was used for pretreatment in allo-HSCT. The primary endpoint of the study was the 2-year cumulative incidence of relapse (CIR) after allo-HSCT, and the secondary endpoints were 2-year overall survival rate (OS), progressing-free survival rate (PFS), non-relapse mortality rate (NRM), graft-versus-host disease (GVHD)-free relapse-free survival (GRFS) rate.
