Patients aged 15 to 60 years , presenting with newly diagnosed acute myeloid leukemia ( AML ) were randomized to receive either high-dose cytarabine , 3 g/m2 12 hourly on days 1 , 3 , 5 , and 7 for 8 doses , daunorubicin 50 mg/m2 days 1 to 3 , etoposide 75 mg/m2 days 1 to 7 , ( HIDAC-3 - 7 ) or standard dose cytarabine 100 mg/m2 continuous intravenous infusion for 7 days with daunorubicin and etoposide at the same dose and schedule as above ( 7 - 3 - 7 ) .
A randomized study of high-dose cytarabine in induction in acute myeloid leukemia. High-dose cytarabine (ara-c) may overcome cytarabine resistance in leukemic blasts. It has been used as a successful salvage and in postremission therapy but not as initial induction treatment. Patients aged 15 to 60 years , presenting with newly diagnosed acute myeloid leukemia ( AML ) were randomized to receive either high-dose cytarabine , 3 g/m2 12 hourly on days 1 , 3 , 5 , and 7 for 8 doses , daunorubicin 50 mg/m2 days 1 to 3 , etoposide 75 mg/m2 days 1 to 7 , ( HIDAC-3 - 7 ) or standard dose cytarabine 100 mg/m2 continuous intravenous infusion for 7 days with daunorubicin and etoposide at the same dose and schedule as above ( 7 - 3 - 7 ) . Patients could receive a second or third induction course if complete remission (CR) was not achieved. All patients received the same postinduction consolidation therapy (5-2-5) for 2 courses. Eligible patients had no prior chemotherapy or myelodysplastic disease. Patients have been followed for a median of 4.5 years. Of 301 patients treated, complete response (CR) was achieved in 71% with HIDAC-3-7 and 74% with 7-3-7. For patients in CR, the estimated median remission duration was 45 months with HIDAC-3-7 and 12 months with 7-3-7 (P = .0005 univariate analysis, P = .0004 multivariate analysis). The estimated percentage of patients relapse free 5 years after achieving a CR was 49% on HIDAC-3-7 and 24% on 7-3-7. Patients in CR tended to survive longer with HIDAC-3-7 but there were no overall survival differences between the two arms. HIDAC-3-7 was associated with significantly more toxicity in induction with more leukopenia, thrombocytopenia, nausea, and vomiting and eye toxicity (all P < .001) but a similar incidence of severe central nervous system and cerebellar toxicity compared to 7-3-7. The consolidation treatment was the same in both arms but caused significantly more leukopenia and thrombocytopenia in patients previously treated with HIDAC-3-7 induction (P < .0001). We conclude that a dose-effect exists for cytarabine in AML and that HIDAC-3-7 prolongs remission duration and disease-free survival and is tolerable when used as initial induction therapy in patients with de novo AML.
