Mitoxantrone and cytarabine versus daunorubicin and cytarabine in previously untreated patients with acute myeloid leukemia.

ABSTRACT

A total of 44 adults aged 18-78 years were allocated to an open randomized study whose aim was to compare the efficacy and toxicity of mitoxantrone with those of daunorubicin in previously untreated patients presenting with acute myeloid leukemia. In one arm, induction treatment consisted of mitoxantrone plus cytarabine given on a 3- plus 7-day schedule. Post-induction treatment consisted of two courses of mitoxantrone plus cytarabine given on a 2- plus 5-day schedule. In the control arm, mitoxantrone was replaced by daunorubicin. In all, 14 of 21 eligible and evaluable patients in the mitoxantrone arm achieved a complete remission (CR). In the control arm, 14 of 20 subjects attained a CR. The median survival was 365 days for patients randomized to mitoxantrone-cytarabine and 401 days for those given daunorubicin-cytarabine. The efficacy and toxicity of mitoxantrone were similar to those of daunorubicin.
