Abstract
Although antithymocyte globulin (ATG) had been widely used in hematopoietic stem cell transplantation from unrelated donor due to its ability to prevent acute and chronic graft-versus-host disease (GVHD), the comparative efficacy and safety of ATG-Thymoglobulin (ATG-T) and ATG-Fresenius (ATG-F) in patients undergoing HLA-mismatched allogeneic peripheral blood stem cell transplantation from unrelated donors (UR-PBSCT) has not been evaluated. Retrospective analysis of patients who underwent HLA-mismatched UR-PBSCT between January 2003 and December 2013 and received pre-transplant ATG-T at a total dose of 10 mg/kg or ATG-F at a total dose of 20 mg/kg was performed. Patients who received ATG-T (n = 23) or ATG-F (n = 28) had similar baseline demographic, disease, and transplant characteristics. There were no significant between-groups differences in the probability of acute GVHD (P = 0.721) and chronic GVHD (P = 0.439). ATG-F was associated with nonsignificant trends toward higher disease-free survival at 3-year follow-up compared with ATG-T (45.7 ± 11.1 vs 61.3 ± 9.7 %, respectively, P = 0.07). A significantly greater proportion of ATG-T patients experienced high fever than ATG-F patients (P < 0.01) during ATG infusion. There was no difference in the rate of infection between the two treatment groups. There were less adverse effects comparing ATG-F with ATG-T. ATG-T at a total dose of 10 mg/kg and ATG-F at a total dose of 20 mg/kg had a similar clinical outcome in the setting of HLA-mismatched UR-PBSCT.
