<section begin="oncology" /><section begin="pathology" /><section begin="radiology" />'''Renal cell carcinoma''' (RCC) is the most common histological type of [[kidney cancer]] in adults, accounting for 80+%. It's a malignant epithelial tumor that arises from the kidney tubules. It's usually discovered incidentally. When symptomatic, it usually presents with a classic triad of haematuria (with normal and not dysmorphic RBCs), costovertebral pain and/or a palpable mass in the flank. | <section begin="urology" /><section begin="oncology" /><section begin="pathology" /><section begin="radiology" />'''Renal cell carcinoma''' (RCC) is the most common histological type of [[kidney cancer]] in adults, accounting for 80+%.

It's a relatively rare malignancy, with an incidence of 15/100 000 new cases every year. It's mostly a disease of elderly men. Most are diagnosed with localised disease. Up to 70% of cases are incidentally diagnosed on imaging.<section end="radiology" /> | It's a relatively rare malignancy, with an incidence of 15/100 000 new cases every year.

Renal cell carcinomas are adenocarcinomas which arise from the tubular epithelium. The most common types are clear cell carcinoma (80%+ of cases) and papillary carcinoma (10% of cases). <section end="oncology" />Other types include: | Renal cell carcinomas are adenocarcinomas which arise from the tubular epithelium.

=== Grading === | === Grading === | ||
The Furhman system is used as grading system for kidney tumors. It’s based mostly on how prominent the nucleoli are – the more prominent, the higher the grade. A grade IV RCC has ''sarcomatoid'' or ''rhabdoid'' appearance. | The Furhman system is used as grading system for kidney tumors.

Targeted therapy may be combined with immune checkpoint inhibitors for palliative therapy of metastatic RCC. These are tyrosine kinase inhibitors like cabozanitinib, sunitinib, or lenvatinib.<section end="oncology" />[[Category:Oncology]] | Targeted therapy may be combined with immune checkpoint inhibitors for palliative therapy of metastatic RCC.
