Hereditary Kidney Cancer Syndromes and Surgical Management of the Small Renal Mass

Abstract

The management of patients with hereditary kidney cancers presents unique challenges to clinicians. In addition to an earlier age of onset compared with patients with sporadic kidney cancer, those with hereditary kidney cancer syndromes often present with bilateral and/or multifocal renal tumors and are at risk for multiple de novo lesions. This population of patients may also present with extrarenal manifestations, which adds an additional layer of complexity. Physicians who manage these patients should be familiar with the underlying clinical characteristics of each hereditary kidney cancer syndrome and the suggested surgical approaches and recommendations of genetic testing for at-risk individuals.
