Wilms' tumor: Riyadh armed forces hospital experience

The aim of this study is to analyse Wilms' tumor cases treated at Riyadh Armed Forces Hospital. twenty patients with Wilms' tumor were identified between January 1983 and November 1995. Mean age at presentation was 38.6 months, ranging from 5 months to 7 years. The prevalence of associated congenital abnormalities was as high as 20%. Females tended to present about 9 months younger and had less advanced disease compared to males. Disease at presentation tended to be advanced with one quarter of patients presenting with stage four disease. The five years disease-free survival probability was 93.5% with a median follow-up of 3 years and 6 months. females tended to present at a younger age, had less advanced disease and a more favourable outcome compared to males. There is an increased prevalence of associated abnormalities compared to international series. Long term survival proved to be similar to international studies
