RCC (Renal Cell Carcinoma)
RCC (Renal Cell Carcinoma)
A type of kidney cancer, arising from the tubular epithelium, responsible for a majority of primary kidney cancers.
Incidence of RCC
Incidence of RCC
RCC accounts for a significant portion (up to 90%) of primary kidney cancers and a relatively small percentage of overall cancers (2-3%).
RCC Predisposing Factors
RCC Predisposing Factors
Factors increasing the risk of RCC include smoking, obesity, hypertension, unopposed estrogen therapy, exposure to asbestos, cadmium, petroleum products, and heavy metals, and acquired cystic kidney disease in dialysis patients.

Study Notes
Renal Cell Carcinoma (RCC)
- RCC accounts for 90% of primary kidney cancers and 2-3% of all cancers.
- Also known as hypernephroma due to its resemblance to adrenal cortex cells.
- Originates from renal tubular epithelium (renal adenocarcinomas).
Epidemiology and Predisposing Factors
- Male to female ratio is 5:2 to 3:1.
- Predisposing factors:
- Smoking
- Obesity
- Hypertension
- Unopposed estrogen therapy
- Exposure to asbestos, cadmium, petroleum products, and heavy metals
- Acquired cystic kidney disease in dialysis patients
Genetic Predisposition to RCC
- Most RCC cases are sporadic.
- 5% are inherited and associated with:
- von Hippel–Lindau (VHL) syndrome:
- Multiple neoplasms (especially haemangioblastomas of cerebellum and retina)
- Multiple bilateral renal cysts
- Pheochromocytomas
- Multicentric bilateral RCC
- Hereditary leiomyomatosis and renal cell cancer syndrome:
- Autosomal dominant inheritance
- Mutation in Fumarate Hydratase (FH) gene
- Uterine and cutaneous leiomyomas
- Aggressive papillary RCC
- Hereditary papillary RCC:
- Autosomal dominant inheritance
- Multiple cytogenetic abnormalities
- Mutation in MET proto-oncogene
- Multiple bilateral papillary RCCs
- Birt–Hogg–Dube (BHD) syndrome:
- Autosomal dominant inheritance
- Mutation in the BHD gene (encoding folliculin)
- Skin appendageal tumors (hair follicle origin)
- Pulmonary cysts
- Renal tumors
- von Hippel–Lindau (VHL) syndrome:
