title: Prognostic factors of patients with acute myeloid leukemia (AML) allografted in first complete remission: an analysis of the EORTC-GIMEMA AML 8A trial. The European Organization for Research and Treatment of Cancer (EORTC) and the Gruppo Italiano Malattie Ematologiche Maligne dell' Adulto (GIMEMA) Leukemia Cooperative Groups.
abstract: The Leukemia Cooperative Groups of the EORTC and the GIMEMA conducted a prospective randomized phase III trial, in order to assess the value of autologous BMT (ABMT) vs a second intensive consolidation course (IC2), following a common intensive consolidation course (IC1) for patients with AML. Patients with an HLA-identical sibling donor were not randomized, but were included in an allogeneic BMT (alloBMT) program. This is an analysis of prognostic factors which influence the outcome of treatment after alloBMT in first complete remission (CR). The study included 730 patients < 46 years of age in CR, 270 having a histocompatible sibling donor. In 169 of these patients alloBMT was performed in first CR. Early remitters (122 patients achieving CR with one course of treatment) had a DFS at 3 years of 67%, significantly longer than that of 44% for late remitters (47 patients achieving CR after more than one course of treatment) (P = 0.006). The relapse risk for early vs late remitters was 16 and 40% at 3 years (P = 0.001) and the treatment-related mortality (TRM) at 2 years was 21 vs 27%. Age appeared to be a prognostic factor for TRM, WBC for DFS, whereas the FAB classification was not of prognostic importance. Patients with poor risk cytogenetic abnormalities showed a trend towards a higher relapse risk. Patients transplanted shortly after achieving CR appeared to have a worse prognosis than those transplanted further into remission. Overall, the number of courses of induction therapy needed to achieve CR was the most important prognostic factor for outcome after allogeneic BMT.
