'''Clear Cell RCC'''
'''Clear Cell RCC'''
This tumor type accounts for 70-75% of all renal cell carcinoma cases (citation needed).
This tumor type accounts for ~70% of all renal cell carcinoma cases.<ref name=eble>Eble JN, Sauter G, Epstein JI, Sesterhenn IA. World Health Organization Classification of Tumours. Pathology and Genetics of Tumours of the Urinary System and Male Genital Organs. Lyon: IARC Press; 2004.</ref>
== Description ==
== Description ==
Malignant epithelial cells with clear cytoplasm and a compact-alveolar (nested) or acinar growth pattern interspersed with intricate, arborizing vasculature. A variable proportion of cells with granular eosinophilic cytoplasm may be present. Infrequently, clear cell renal cell carcinoma has a distinct tubular pattern and rarely a pseudopapillary architecture is focally present."

== Main Pathways Involved ==
1) Loss of VHL function results in an uncoupling of an oxygen-sensing pathway, which results in stabilization and activation of the HIF transcription factors, leading to overexpression of a number of factors that promote proliferation, cell survival, angiogenesis, and metabolic changes, such as vascular endothelial growth factor (VEGF), platelet-derived growth factor (PDGF), and epidermal growth factor (EGF). 2) histone acetyltranferases/components of the SWI/SNF complex; mutations in chromosome 3p chromatin modifiers PBRM1, SETD2 and BAP1 associated with widspread alterations in transcription or methylation MAP kinase pathway phosphoprotein signature PI3K/AKT and mTOR pathways elevated; high expression of several genes representing targets for immunotherapy including PDCD1, CD247, PDCD1LG2, CTLA4, TNFRSF9, TNFRSF4

Loss of 14, loss of 9p, loss of 18q and highly complex genotype are associated with high risk histological features and adverse clinical outcome, also significantly associated with high risk histologic features: loss of 1p, 4p, 9q, 15q, 16q, 17p, 18p, 21q, 22q and gains of 3q, 5p, 7p, 7q, 17q.<ref>Wolff, Nicholas C, Andrea Pavía-Jiménez, Vanina T Tcheuyap, Shane Alexander, Mridula Vishwanath, Alana Christie, Xian-Jin Xie, Noelle S Williams, Payal Kapur, Bruce Posner, Renée M Mckay, and James Brugarolas.
