Summary

Allo-HSCT is the most effective way to cure high-risk MDS patients. At present, the best conditioning regimen for high-risk MDS patients undergoing allo-HSCT remains in discussion. In this prospective study, the safety and efficacy of G-CSF+DAC+BUCY and G-CSF+DAC+BF conditioning regimens in high-risk MDS patients undergoing allo-HSCT are evaluated.

Detailed description

Allo-HSCT is the most effective way to cure high-risk MDS patients. At present, the best conditioning regimen for high-risk MDS patients undergoing allo-HSCT remains in discussion. A previous study by the investigators 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 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, the investigators 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 high-risk MDS patients undergoing allo-HSCT.

DRUG	Decitabine (DAC)	Decitabine was administered at 20mg/m2/day on days -14 to -10.
DRUG	Busulfan	Busulfan was administered at 3.2 mg/kg/day on days -7 to -4 in G-CSF+DAC+BUCY group.
DRUG	Fludarabine (FLU)	Fludarabine was administered at 30 mg/m2/day on days -7 to -3.
DRUG	Cyclophosphamide (CY)	Cyclophosphamide was administered at 60 mg/kg/day on days -3,-2.
DRUG	Busulfan (BU)	Busulfan was administered at 3.2 mg/kg/day on days -6 to -3 in G-CSF+DAC +BF group.
