摘要: Summary Prior therapy with rituximab might attenuate disparate histocompatibility antigen presentation by B cells, thus decreased the risk of acute graft-versus-host disease (GVHD) and improved survival. We tested this hypothesis comparing outcomes 435 B-cell lymphoma patients who received allogeneic transplantation from 1999 to 2004 in Center for International Blood Marrow Transplant Research database: 179 subjects within 6 months prior (RTX cohort) 256 did not receive RTX (No-RTX cohort). The cohort had a significantly lower incidence treatment-related mortality (TRM) [relative (RR) = 0·68; 95% confidence interval (CI), 0·47–1·0; P = 0·05], grade II–IV (RR = 0·72; CI, 0·53–0·97; P = 0·03) III–IV GVHD (RR = 0·55; 0·34–0·91; P = 0·02). There was no difference chronic GVHD, progression or relapse. Progression-free survival (PFS) (RR = 0·68; CI 0·50–0·92; P = 0·01) overall (OS) (RR = 0·63; 0·46–0·86; P = 0·004) were better cohort. Prior correlated less similar TRM, PFS OS.
