Fifty-seven previously untreated adult acute myeloid leukemia patients received idarubicin (IDA) in sequential combination with cytarabine as induction therapy; post-remission treatment included two courses of IDA and cytarabine alternating with two courses of VP-16 and cytarabine. As late intensification, patients received either high-dose cytarabine or, in 10 cases, autologous bone marrow transplantation. Complete remission (CR) was achieved in 48 patients (84.2%), 41 after one induction course and seven after two courses. Median length of disease-free survival (DFS) was 26 months. Univariate analysis did not identify any of the investigated variables as having prognostic significance in predicting DFS. On the other hand, patients achieving CR after one induction course had a better DFS than those requiring two courses. Furthermore, the analysis of DFS slightly favors autologous bone marrow transplantation. In conclusion, the antileukemic activity of the present IDA protocol is testified by the high CR rate and by the possibility of minimizing the role of prognostic factors. The better outcome of patients achieving CR after one induction course further supports the opinion that the intensity of the induction treatment, offered by an agent as potent as IDA, might significantly influence DFS.
