title: Results of induction and consolidation treatment with intermediate and high-dose cytosine arabinoside and m-Amsa of patients with poor-risk acute myelogenous leukaemia.
abstract: 50 patients (aged 18-58 years) with acute myelogenous leukaemia after a preleukaemic phase (n = 14), acute myelogenous leukaemia that previously failed to respond to conventional chemotherapy (n = 9) or relapsed disease (n = 27) were given remission induction therapy consisting of cytosine arabinoside (1 g/m2 q 12 h x 12) and m-Amsa (115 mg/m2 for 1 or 3 days). Overall, 27 patients (54%) achieved complete remission. The complete remission rate for patients with acute myelogenous leukaemia after a preleukaemic phase (7/14) and those with primary refractory or relapsed leukaemia (20/36) seems superior to that obtained with conventional remission-induction therapy. 12 patients received 1-3 courses of consolidation chemotherapy with cytosine arabinoside (3 g/m2 q 12 h x 8) and m-Amsa (115 mg/m2 for 1 d). 3 of them subsequently underwent autologous bone marrow transplantation. The median duration of remission for the remaining 9 patients was 8 months. 11 patients did not receive consolidation therapy; their median duration of remission was 3 months. The difference between the two groups was not significant. 4 patients underwent allogeneic bone marrow transplantation after achievement of complete remission. The impact of high-dose cytosine arabinoside consolidation chemotherapy on poor-risk acute myelogenous leukaemia remains unclear.
