title: Cyclophosphamide/etoposide: effective reinduction therapy for children with acute nonlymphocytic leukemia in relapse.
abstract: Reinduction therapy consisting of cyclophosphamide (250 mg/m2 orally daily for 4 days) followed by etoposide (250 mg/m2 iv daily for 3 days) was administered to 14 children with refractory or recurrent acute nonlymphocytic leukemia. Five complete remissions were achieved in eight patients who had relapsed in the bone marrow 1-27 months after cessation of initial therapy, which included anthracyclines, cytarabine, etoposide, and 5-azacitidine. Reinduction attempts were unsuccessful in patients who had failed to achieve an initial remission and in those whose relapses occurred while receiving therapy. Toxicity, including myelosuppression and mucositis, was within acceptable limits. This drug combination deserves further assessment in therapeutic protocols for patients with acute nonlymphocytic leukemia.
