简要总结
Recent studies demonstrated that allogeneic hematopoietic stem cell transplantation (allo-HSCT) could be a valuable treatment choice for mixed-lineage-leukemia (MLL)-rearranged acute leukemia. Unfortunately, some patients relapsed after allo-HSCT. In this prospective randomized controlled study, the safety and efficacy of Decitabine + BUCY and BUCY myeloablative conditioning regimens in MLL+ acute leukemia undergoing allo-HSCT are evaluated.
详细描述
Recent studies demonstrated that allogeneic hematopoietic stem cell transplantation (allo-HSCT) could be a valuable treatment choice for mixed-lineage-leukemia (MLL)-rearranged acute leukemia. BUCY conditioning regimen is the standard myeloablative regimen for MLL+ acute leukemia undergoing allo-HSCT. However, it appears to have higher relapse rate and lower survival. To reduce the relapse rate and improve the survival, decitabine is added in the conditioning regimen. In this prospective randomized controlled study, the safety and efficacy of Decitabine + BUCY and BUCY myeloablative conditioning regimens in MLL+ acute leukemia undergoing allo-HSCT are evaluated.
