## Abstract A British populationβbased cohort study was carried out to determine the risk of second primary neoplasms in survivors of Wilms' tumour. The cohort was obtained from the British Childhood Cancer Survivor Study, a populationβbased cohort study of treatment toxicities in 18,044 individual

Abstract
Eight second malignant tumours developed in a populationβbased series of 218 patients diagnosed with renal tumours in childhood: renal cell carcinoma of the contralateral kidney, hepatocellular carcinoma, Hodgkin's disease, and 4 basal cell and 1 squamous cell carcinomas of skin. Excess risk of developing a second malignancy (excluding skin carcinomas but including a registrable spinal neurofibroma) was 14.7 (95% Cl 4.0β37.7, P = 0.0003) for Wilms' tumour patients. Cumulative incidence of second malignant neoplasms (excluding skin carcinoma) was zero at 10 years, 5.0% at 20 years, and 10.2% at 30 years. The most common second neoplasms seen were benign osseous/chondromatous tumours and 4 of the 7 Wilms' tumour patients with malignant tumours had previous or synchronous tumours of this kind. Development of bony exostoses may be a marker for those patients at particularly high risk of subsequent malignancy. Β© 1994 wileyβLiss, Inc.

We studied second primary cancer among 25,947 patients diagnosed with squamous cell carcinoma of the skin (SCC) in Sweden between 1958 and 1992. In total, 5,706 patients developed a second primary cancer at any site, compared with an expected number of 2,651 [standardized incidence ratio (SIR) β«Ψβ¬ 2
