BACKGROUND: Both immunosuppressive therapy and bone marrow transplantation are accepted treatments for patients with aplastic anemia. Choosing one of these therapies for a given patient depends not only on donor availability but also on such factors as patient age. OBJECTIVE: To compare survival rates and long-term complications after bone marrow transplantation or immunosuppressive therapy in patients with acquired aplastic anemia and to identify prognostic factors associated with improved survival. DESIGN: Center-based, retrospective analysis. SETTING: Referral center for patients with aplastic anemia. PATIENTS: 395 patients with acquired aplastic anemia. INTERVENTION: Bone marrow transplant from an HLA-identical, related donor or immunosuppressive therapy. MEASUREMENTS: Kaplan-Meier survival curves, results of log rank tests, and cumulative incidence curves. RESULTS: Of 168 bone marrow transplant recipients, 89% had sustained engraftment. Forty-six patients developed grade II to IV acute graft-versus-host disease, and 68 developed chronic graft-versus-host disease that required therapy. Of 227 patients who received immunosuppressive therapy, 44% achieved a complete, partial, or minimal response. Fifty-four percent died or had no response to therapy. Actuarial survival at 15 years was 69% for bone marrow transplant recipients and 38% for patients receiving immunosuppressive therapy (P < 0.001). Improved survival was associated with having bone marrow transplantation as prim...
