OBJECTIVETo evaluate the efficacy of decitabine (DAC) bridging therapy followed by allogeneic hematopoietic stem cell transplantation (allo-HSCT) in patients with myelodysplastic syndrome (MDS).
METHODSThe clinical characteristics and curative effect of MDS patients who received allo-HSCT from 2010 July to 2013 December were retrospectively analyzed. Of them, 25 MDS patients who received decitabine bridging allo-HSCT were randomly selected (referred to as the bridging group),while at the same time another 33 MDS patients who did not receive decitabine for allo-HSCT in MDS were also randomly selected as control group. The effect of decitabine bridging allo-HSCT on the patients' survival and occurrence of graft versus host disease (GVHD) was analyzed.
RESULTSWith decitabine bridge therapy, 64.0% patients (16/25) achieved marrow complete remission before allo-HSCT, while the control group was only 15.1% (5/33, P<0.05). Decitabine bridging group of early transplant-related mortality was lower than that of the control group (4.0% vs 18.2%), but the difference was not statistically significant (P=0.106). Up to follow-up deadline, the mortality of decitabine bridging group was 12.0%, while that of the control group was 30.3% (P<0.05). The 2-year OS of decitabine bridging group was 83.0%, while that of the control group was 59.0% (P<0.05). Of the 14 patients in decitabine bridging group with aGVHD, 7 was grade IaGVHD, 3 grade II and 4 grade III. Of the 16 patients in control group with aGVHD, 7 was grade IaGVHD, 8 grade II and 1 grade III.
CONCLUSIONDecitabine bridging therapy followed by allo-HSCT in the treatment of MDS is safe and effective.
