AbstractOne hundred patients were entered in a cooperative study comparing the efficacy of two different regimens in the induction treatment of acute nonlymphocytic leukemia (ANLL). Patients were randomly allocated to receive either the DAT or VAT combination; half of the patients were also randomized to receive CNS prophylaxis including intrathecal methotrexate + prednisone and cranial irradiation. Consolidation and maintenance therapy were uniform in responding patients. Out of 82 evaluable patients 41 (50%) attained complete remission (CR) with no significant difference between the two regimens. Median remission duration was slightly longer in the DAT group (32.5 vs 22 weeks); median survival was 34 weeks for all evaluable patients with no difference between the two schedules. Meningeal relapse occurred only in two patients after 19 and 99 weeks of continuous remission. Fourteen patients are still alive after 61 to greater than or equal to 155 weeks, of whom seven are in their initial remission (six in the DAT and one in the VAT group). We conclude that 1) DAT and VAT are equally effective in inducing CR in a high proportion of ANLL patients; 2) until marrow remission can be prolonged significantly, preventing CNS leukemia will not have any significant impact of the course of ANLL.
