Genetic transmission of susceptibility to cancer in families of children with soft tissue sarcomas.
Cancer 1996 October 2
BACKGROUND: This article presents analysis of clinical and family data for 239 patients with childhood soft tissue sarcoma (STS) treated at the Institut Gustave Roussy in Villejuif.
METHODS: A molecular study was performed to detect germline p53 mutations in the 44 families in which at least 1 relative developed cancer before the age of 46 or in which the proband had a second neoplasm. Mutations were found in five families. Standardized incidence ratio calculation and segregation analysis were used to study cancer occurrence in 4448 relatives, including first- and second-degree relatives and first cousins.
RESULTS: An excess of brain tumors was observed in all relatives, and of breast carcinoma and STS in first-degree relatives of patients with STS. An excess of breast carcinoma was observed only in young mothers of patients with rhabdomyosarcoma. This excess might be mostly linked to the presence of a germline p53 mutation because it was no more significant when excluding families in which such a mutation existed. No association between breast carcinoma in the mother and rhabdomyosarcoma of the genitourinary tract in the proband was observed. This should be kept in mind when developing a screening strategy for breast carcinoma in mothers of patients with STS. Segregation analysis showed evidence for transmission of an autosomal dominant gene with complete penetrance by the age of 84. The genetic component was explained primarily by p53 germline mutations.
CONCLUSIONS: These results show that most relatives of patients with STS are at the same risk for cancer as the general population.
