    PurposeTo evaluate prospectively the feasibility and results of bone marrow transplantation (BMT) after induction and intensification chemotherapy (CT) in patients with de novo acute myeloid leukemia (AML).Patients And MethodsA total of 159 patients less than 51 years of age were treated. Induction CT consisted of daunorubicin 60 mg/m2 for 3 days, cytarabine (ARA-C) 100mg/m2 for 7 days, and etoposide 100 mg/m2 for 3 days. The first intensification therapy included mitoxantrone 10 mg/m2 for 3 days and ARA-C 1.2 g/m2 every 12 hours for 4 days. Amsacrine (100 or 150 mg/m2 for 3 days) and ARA-C (1.2 g/m2 every 12 hours for 2 or 4 days) were given as the second intensification therapy. Depending on the availability of a human leukocyte antigen (HLA)-identical sibling, the intention of treatment after CT was allogeneic BMT (allo-BMT) or autologous BMT (ABMT).ResultsComplete remission (CR) was obtained in 120 patients (75%) and partial remission (PR) in 11 (7%), while 15 patients (10%) were refractory and 13 (8%) died during induction. There was a trend for better leukemia-free survival (LFS) at 4 years for patients assigned to the ABMT group (50% +/- 6%) compared with the allo-BMT group (31% +/- 7%) (P = .08). This difference in LFS reached statistical significance when considering only transplanted patients (63% +/- 3% at 4 years after ABMT and 38% +/- 11% after allo-BMT, P = .02). The favorable results in patients who received ABMT (no toxic deaths and 37% +/- 7% probability of relapse at 4 years) contrast with the poor outcome of allografted patients (11 patients with transplant-related mortality).ConclusionOur study reflects the difficulties in the completion of a therapeutic strategy that include BMT and suggests that intensification before BMT may be useful in the setting of ABMT, but this approach was associated with a high mortality rate in allo-BMT patients.
