Between 1976 and 1988 we treated 228 children age 18 years or less with AML on three consecutive protocols: Vapa, 80-035 and Hi-C Daze. All three protocols used intensive consolidation chemotherapy. VAPA and 80-035 used an anthracycline with standard dose cytosine arabinoside (ara-c) for remission induction followed by twelve to fourteen months of intensive sequential chemotherapy. Results were similar for these two treatment protocols. 90/125 (72%) of the patients achieved a complete remission with 45% projected disease free survival for the complete responders, and an event free survival of 31%. 8/26 (VAPA) and 3/21 (80-035) relapses were primary CNS. No factor significantly influenced the rate of complete remission, but M4 and M5 FAB subtypes and WBC greater than 100,000/ul predicted for shorter remission duration. 103 children received Hi-C DAZE. The protocol differed by utilizing high-dose ara-c during induction and consolidation and pairing VP-16 with azacytidine. Hi-C DAZE was modified after the first 33 patients (group 1) because of CNS toxicity; VP-16/azacytidine were substituted for high dose ara-c/daunorubicin as the second induction course for the next 70 patients (group 2). Twenty eight of 33 (85%) of group 1 and 54/70 (77%) of group 2 entered remission.
