Twenty-one children, between eight months and twelve years old, diagnosed as having acute nonlymphoblastic leukemia (ANLL), were treated with an intensive chemotherapy based on a modified VAPA protocol. Complete remission rate was 80%, and the 5 year-survival rate is 46%. One chloroma, one central nervous system, and four bone marrow relapses were observed; all except the first having an unfavourable outcome. Significant risk prognostic factors in this series proved to be hepatomegaly (greater than 5 cm) and delay in obtaining remission. No fatal complications were observed.
