Myelodysplastic Syndrome, Allogeneic Hematopoietic Stem Cell Transplantation, Conditioning
Conditions
Brief summary
Allogeneic hematopoietic stem cell transplantation (allo-HSCT) appears to be an efficient tool to cure refractory anemia with excess blasts-1 (RAEB-1), refractory anemia with excess blasts-2 (RAEB-2) and acute myeloid leukemia (AML) secondary to myelodysplastic syndrome (MDS). At present, the best conditioning regimen for RAEB-1, RAEB-2 and AML secondary to MDS undergoing allo-HSCT remains in discussion. In this prospective randomized controlled study, the safety and efficacy of G-CSF+ Decitabine + BUCY and BUCY myeloablative conditioning regimens in patients with RAEB-1, REAB-2 and AML Secondary to MDS undergoing allo-HSCT are evaluated.
Detailed description
Allo-HSCT appears to be an efficient tool to cure patients with MDS and AML secondary to MDS. At present, the best conditioning regimen for MDS and AML secondary to MDS undergoing allo-HSCT remains in discussion. BUCY conditioning regimen is the standard myeloablative regimen for MDS and AML secondary to MDS undergoing allo-HSCT. However, it appears to have higher relapse rate. To reduce the relapse rate, decitabine is added in the conditioning regimen. In this prospective randomized controlled study, the safety and efficacy of G-CSF + Decitabine + BUCY and BUCY myeloablative conditioning regimens in RAEB-1, REAB-2 and AML secondary to MDS undergoing allo-HSCT are evaluated.
Interventions
Decitabine was administered at 20mg/m2/day on days -14 and -10.
Busulfan was administered at 3.2 mg/kg/day on days -7 to -4.
Cyclophosphamide was administered at 60 mg/kg/day on days -3 to -2.
G-CSF was administered at 5-10 ug/kg/day on days -17 and -10. When white blood cell is more than 20G/L, stop using G-CSF.
