✦ Synopsis

Abstract

A complete family history was obtained for 501 patients with Wilms' tumor, treated in departments of pediatric oncology in whole France. The information was collected by self‐questionnaire and/or by interview of parents. The proportion of bilateral cases is 4.6% and there are 12 patients (2.4%) with a positive family history of Wilms' tumor. The affected relatives are most often distant and no first degree relative was affected. Apart from the well‐known associations with aniridia, hemihypertrophy, genitourinary anomalies, Beckwith‐Wiedeemann, and Drash syndromes, there is also a significant excess of congenital heart defects (P = .008) which remains to be explained. Several findings support the bimutational hypothesis such as earlier diagnosis and increased parental age in bilateral cases. No particular anomalies and no increased frequency of childhood cancer were found in patients' relatives. The frequency of Wilms' tumor in relatives was estimated to be less than 0.4% in sibs, 0.06% in unclesand aunts, and 0.04% in first cousins. These figures are very different from those found in retinoblastoma and suggest that the mechanism may be more complex in Wilms' tumor. This conclusion is in agreement with molecular biology studies in tumors and linkage analysis in multiple case families which suggest that more than one locus is involved. © 1992 Wiley‐Liss, Inc.

Wilms tumor (WT), a sporadic and familial childhood kidney tumor, is genetically heterogeneous. One WT gene, WT1 at 11p13, has been cloned, but only a minority of WTs carry detectable mutations at that locus. WT1 can also be excluded as the predisposition gene in most WT families, implying the exist

Epidemiology is the study of the distribution of disease in human populations and the factors that determine that distribution. There are two main types of epidemiologic research descriptive and analytic. Descriptive studies focus on the incidence of disease regarding person, place, and time. Such s
