title: [Wilms' tumor. Clinico-prognostic correlates].
abstract: A series of 42 children with Wilms' tumor collected in 11 years is reported. The female-to-male ratio was 1,5:1 and 85 per cent of the patients were under 5 years at diagnosis. The majority of the tumors were Stage I (38 per cent) followed by Stages III and IV. Pathological findings following Belkwith's criteria are commented upon. The 5 year survival was 72 per cent, and tumor-free survival was 62 per cent. There was a clear relationship between survival and Stage, age and the presence or absence of intra-abdominal lymph-node spread. Efficacity of preoperative chemotherapy and its' influence on the stage of tumor at operation is discussed.
