Description

Allo-HSCT is the most effective way to cure secondary acute myeloid leukemia evolving from MDS (sAML) patients. At present, the best conditioning regimen for sAML patients undergoing allo-HSCT remains in discussion. Our previous study has showed that G-CSF+DAC+BUCY conditioning regimen could reduce the relapse and improve the survival compared with BUCY conditioning regimen, while the two conditioning regimens both have high non-relapse mortality (NRM). Several retrospective and prospective studies including ours have demonstrated that BF conditioning regimen has a lower NRM compared with BUCY conditioning regimen, while the relapse and survival are similar in patients undergoing BF and BUCY conditioning regimens. Based on the above, we design the prospective randomized controlled study to evaluate the safety and efficacy of G-CSF+DAC+ BUCY and G-CSF+DAC+BF conditioning regimens in sAML patients undergoing allo-HSCT.
