title: [An early phase II study of autologous peripheral blood stem cell transplantation for acute myelogenous leukemia in first remission. Japan Blood Cell Transplantation Study Group].
abstract: We performed a multicenter, an early phase II clinical trial to evaluate the feasibility, safety and efficacy of myeloablative therapy supported by autologous peripheral blood stem cell transplantation (auto-PBSCT) for the treatment of acute myelogenous leukemia (AML) in first remission. A total of 105 patients were enrolled in the study, and 56 patients in first complete remission received auto-PBSCT. The median age was 44 years. Of the 56 patients, 34 (60.7%) had M2 or M3 AML by the French-American-British Classification system. The median concentration of infused CD34+ cells was 2.3 x 10(6)/kg by recipient body weight. Median days to reach an absolute neutrophil count > 500/microliter and a platelet count > 20000/microliter were 14 and 16, respectively. The median disease-free survival rate was estimated to be 62.0% at a median follow-up time of 534 days. Although the study enrolled a small number of patients and the follow-up period was relatively short, the preliminary results were encouraging and indicated that myeloablative chemotherapy with auto-PBSCT is feasible and can be performed safely as a post-remission therapy for AML. A prospective randomized clinical trial of auto-PBSCT versus standard chemotherapy alone will be necessary to assess the efficacy of high-dose therapy facilitated by auto-PBSCT as a post-remission therapy for AML.
