[Wilms' tumor. Our clinical experience].

The survival of children with Wilms' tumour is evaluated in 11 males and 12 females treated between 1967 and 1975 in the light of the clinical stage, age at diagnosis, and sex. The subjects were aged from 4 months to 6 years. Six were in stage I, 4 in stage II, 4 in stage III, 7 in stage IV, and 2 in stage V. Survival in stage I was 100% at 36 months and gradually decreased with the stage. Patients aged less than 2 years presented a survival of 50% two years after diagnosis, compared to 24% in those over 2 years old. Sex appears to be irrelevant to prognosis.
