Conceptos Básicos
Hereditary renal cell carcinoma (RCC) is associated with genetic syndromes that require early diagnosis and targeted management to improve patient outcomes.
Resumen
The content discusses the current evidence on hereditary RCC, focusing on the key aspects of early diagnosis and management. It highlights the following:
- Hereditary RCC accounts for 2-8% of all RCC cases and is linked to various genetic syndromes, such as Von Hippel-Lindau (VHL) syndrome, hereditary papillary RCC, and Birt-Hogg-Dubé syndrome.
- Patients with hereditary RCC are typically younger (≤ 45 years) and present with bilateral or multifocal renal tumors, skin leiomyomas, or other associated manifestations.
- VHL syndrome is one of the more common hereditary RCC syndromes, characterized by clear cell RCC and other clinical features like central nervous system hemangioblastomas, retinal hemangioblastomas, and pheochromocytomas.
- Genetic risk assessment, including personal and family history, physical examination, and genetic counseling, is recommended to identify individuals at risk of hereditary RCC.
- Genetic testing can significantly impact patient management, as it allows for early detection and targeted surveillance of VHL-associated neoplasms.
- In the next 5 years, advancements in genetic testing and biomarkers are expected to lead to earlier diagnosis and the development of prevention strategies and targeted therapies for hereditary RCC syndromes beyond VHL.

Citas
"It is estimated that 2%-8% of RCCs have a hereditary component associated with germline pathogenic variants that may lead to specific types of tumors in different organ systems, including kidney, skin, and central nervous system."
"Typically, patients are younger (≤ 45 years of age) and present with bilateral or multifocal renal tumors, skin leiomyomas, or pheochromocytomas/hemangioblastomas, or report a family member with a clinical or genetic diagnosis of one of these syndromes."
