Improved survival for patients with acute myelogenous leukemia.

PURPOSEDespite improvement in chemotherapy and supportive care over the past two decades, overall survival for patients with acute myelogenous leukemia (AML) remains poor; only 25% to 30% of individuals with this disorder will be cured. In 1987, we initiated a prospective multiinstitution study designed to improve long-term survival in adults with AML.METHODSWe modified the usual 7-day treatment scheme of daunorubicin and cytarabine with high-dose cytarabine (HiDAC) on days 8 through 10 (3 + 7 + 3). Allogeneic or autologous bone marrow transplantation (BMT) was offered to all patients who entered complete remission (CR) to decrease the rate of leukemic relapse. Data were analyzed by intention to treat.RESULTSCRs were achieved in 84 of 94 patients (89%; 95% confidence interval [CI], 83 to 95). Because of the high remission rate, factors previously thought to predict outcome, such as cytogenetics, WBC count, French-American-British (FAB) classification, sex, and age, were not useful prognostic variables.
