Zusammenfassung: | Graft-versus-host disease (GVHD) is one of the leading causes of non-relapse mortality and morbidity after allogeneic hematopoietic stem cell transplantation (allo-HCT).
We evaluated the outcomes of two well-established strategies used for GVHD prevention: in vivo T cell depletion using antithymocyte globulin (ATG) and ex vivo T cell depletion using a CD34-selected (CD34+) graft. A total of 525 adult patients (363 ATG, 162 CD34+) with intermediate or high-risk cytogenetics acute myeloid leukemia (AML) in first complete remission (CR1) were included. Patients underwent myeloablative allo-HCT using matched related or unrelated donors.
Two-year overall survival estimate was 69.9% (95% CI, 58.5-69.4) in the ATG group and 67.6% (95% CI, 60.3-74.9) in the CD34+ group (p = 0.31). The cumulative incidence of grade II-IV acute GVHD and chronic GVHD was higher in the ATG cohort [HR 2.0 (95% CI 1.1-3.7), p = 0.02; HR 15.1 (95% CI 5.3-42.2), p |
