Purpose: Approximately 5% to 8% of renal cell carcinoma (RCC) is hereditary. No guidelines exist for patient selection for RCC germline mutation testing. We evaluate how age of onset could indicate the need for germline mutation testing for detection of inherited forms of kidney cancer. Patients and Methods: We analyzed the age distribution of RCC cases in the SEER-17 program and in our institutional hereditary kidney cancer population. The age distributions were compared by sex, race, histology, and hereditary cancer syndrome. Models were established to evaluate the specific age thresholds for genetic testing. Results: The median age of patients with RCC in SEER-17 was 64 years, with the distribution closely…(ver más)
