Abstract

To evaluate the efficacy of decitabine (DAC) bridging therapy followed by allogeneic hematopoietic stem cell transplantation (allo-HSCT) in patients with myelodysplastic syndrome (MDS). The 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. With 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 decit...Continue Reading

Blood And Marrow Transplantation

The use of hematopoietic stem cell transplantation or blood and marrow transplantation (bmt) is on the increase worldwide. BMT is used to replace damaged or destroyed bone marrow with healthy bone marrow stem cells. Here is the latest research on bone and marrow transplantation.

Allogenic & Autologous Therapies

Allogenic therapies are generated in large batches from unrelated donor tissues such as bone marrow. In contrast, autologous therapies are manufactures as a single lot from the patient being treated. Here is the latest research on allogenic and autologous therapies.
