Detailed Description
Poor graft function (PGF), defined by the presence of multilineage cytopenias in the presence of 100% donor chimerism, is a serious complication of allogeneic stem cell transplant (allo-HSCT). Emerging evidence demonstrates that the inadequate stem cells infusion, bone marrow microenvironment and immune dysregulation play a crucial role in maintaining and regulating hematopoiesis. Current therapies remain debatable, including selected CD34+ cells infusion, mesenchymal stromal cells infusion, prophylactic N-acetyl cysteine administration, etc. Thereafter, the investigators conduct a randomized trial aiming at validating the efficacy and safety of low-dose decitabine in PGF post allo-HSCT patients.
