Résumé
What's known on the subject? and What does the study add? Hereditary non-polyposis colorectal cancer (HNPCC), also known as Lynch syndrome, is an autosomal dominant multi-organ cancer syndrome. Upper urinary tract urothelial carcinomas belong to HNPCC-related tumours and rank third within this group after colorectal and endometrial cancer. However, many urologists are not aware of this association and it is presumed that some hereditary cancers are misclassified as sporadic and that their incidence is underestimated. Consequently, family members of patients with upper urinary tract urothelial carcinomas secondary to HNPCC may be denied appropriate surveillance and early detection. A significant proportion of patients (21.3%) with newly diagnosed upper urinary tract urothelial carcinomas may have underlying HNPCC. Demographic and epidemiological characteristics suggest different mechanisms of carcinogenesis among this population. Recognition of such potential is essential for appropriate clinical and genetic management of patients and family. In order to help to identify these patients, we propose a patient-specific checklist. OBJECTIVE: * To identify, based on previously described clinical criteria, hereditary upper urinary tract urothelial carcinomas (UUT-UCs) that are likely to be misclassified as sporadic although they may belong to the spectrum of hereditary non-polyposis colorectal cancer (HNPCC) associated cancers. PATIENTS AND METHODS: * We identified, using established clinical criteria, suspected hereditary UUT-UC among 1122 patients included in the French national database for UUT-UC. * Patients were considered at risk for hereditary status in the following situations: age at diagnosis
