Combination of cyclosporin and methotrexate for prophylaxis of acute graft-versus-host disease after allogeneic bone marrow transplantation for leukemia.

From May 1985 to July 1989, 76 patients with leukemia (30 acute myelogenous leukemia, 24 acute lymphoblastic leukemia and 22 chronic myeloid leukemia) were randomized to receive either cyclosporin (CSP) alone (n = 39) or CSP combined with methotrexate (CSP + MTX, n = 37) for graft-versus-host disease (GVHD) prophylaxis. Patients were conditioned with total body radiation and cyclophosphamide followed by bone marrow infusion from an HLA-identical sibling. Engraftment of the transplanted bone marrow was similar in both groups. The incidence of moderate to severe acute GVHD was significantly higher in the CSP group compared with the CSP + MTX group (20 (51%) versus 9 (25%), chi 2 = 4.76, p less than 0.02). There was no significant difference in the incidence of chronic GVHD. Survival was significantly better for the CSP + MTX group (63 +/- 16%) compared to CSP alone (42 +/- 18%). Leukemia-free survival tended to be better for the CSP + MTX group (55 +/- 17% versus 32 +/- 16%).
