[Good prognosis childhood cancers].

Wilms' tumours, neuroblastomas occurring in patients aged less than 1 year or localized neuroblastomas in older patients, malignant germ cells tumours, Hodgkin's disease, and malignant non Hodgkin lymphomas can be cured in more than 80% of the cases with treatment strategies adapted to risks factors in each tumour. The knowledge of low risk groups of patients allows the decrease of cumulative doses of alkylating agents and anthracyclines and limits the use of irradiation in order to reduce long term sequelae.
