Multicenter StudyRisk assessment and outcome of chronic graft-versus-host disease after allogeneic peripheral blood progenitor cell transplantation in pediatric patients.
We retrospectively evaluated the incidence, risk factors for chronic graft-versus-host disease (cGvHD) and outcome in 80 pediatric patients (36 male) (median age 13 years) who underwent allogeneic peripheral blood progenitor cell transplantation. Patients were grafted from an HLA-identical sibling after myeloablative conditioning (total body irradiation (TBI) based 52; non-TBI 28). GvHD prophylaxis used were: cyclosporin A (CsA)+ short methotrexate (MTX) in 52 and CsA+/-prednisone in 28. ⋯ The probability of disease-free survival was better for patients with cGvHD (69.9+/-10 vs 37.9+/-7%; HR: 3.59, 95% CI: 1.47-5.56; P=0.001). Our data suggest that the GvHD prophylaxis used is the most relevant predictor of cGvHD. Patients with cGvHD had a lower risk of relapse and a better survival.

Comparative Study Clinical TrialTacrolimus as monotherapy or combined with minidose methotrexate for graft-versus-host disease prophylaxis after allogeneic peripheral blood stem cell transplantation: long-term outcomes.
We report long-term outcomes for allogeneic peripheral blood stem cell (PBSC) recipients, evaluating cumulative incidence (CI) of acute and chronic graft-versus-host disease (GVHD), after use of tacrolimus with or without minidose methotrexate for GVHD prophylaxis. From April 1996 to April 1998, 97 adults underwent allogeneic PBSC transplantation. The first 49 received tacrolimus monotherapy as GVHD prophylaxis and the subsequent 48 received combination therapy. ⋯ Within the good-risk disease category, patients receiving methotrexate had a trend towards improved OS (P=0.07). Multivariate analysis indicated good-risk disease status and methotrexate were independently associated with improved OS, progression-free survival (PFS), and relapse. In addition, patients developing chronic GVHD had a significantly reduced risk of relapse and improved PFS.
