ABSTRACT
Graft-versus-host disease (GVHD) is one of the major complications after allogeneic hematopoietic stem cell transplantation (allo-HSCT), which seriously affects the prognosis of patients. At present, a new regimen of post-transplantation cyclophosphamide (PTCy) combined with antithymocyte globulin (ATG) has been used to prevent GVHD, indicating that PTCy combined with ATG may have a good effect on the prevention of GVHD in different types of transplantation. However, the mechanism of this regimen, its effect on immune reconstitution and viral reactivation still needs to be further studied. Therefore, this article briefly reviews the research progress of PTCy combined with ATG in preventing GVHD after HSCT.

AIM: To investigate the therapeutic method of fludarabine combined with subsequent cyclophosphamide in the prevention of GVHD in haploid hematopoietic stem cell transplantation. METHODS: A total of 52 patients receiving PTCY (50 mg/kg, on days 3 and 4) were matched with 29 patients receiving ATG. RESULTS: The median follow-up time was 359 days. Complete donor chimerism was achieved in all patients by STR DNA detection on days +30, +60. The median time to neutrophils ≥0.5×10
