Renal cell carcinoma, or RCC, is also called hypernephroma, adenocarcinoma of renal cells, or renal or kidney cancer. Almost all cases of ccRCC that run in families are found in people with a genetic condition called Von Hippel-Lindau syndrome, but other hereditary conditions may also be associated with ccRCC. However, these biomarkers have not had strong predictive value in clear cell renal cell carcinoma, suggesting that the immune tumor environment may be more unique and complex compared to other tumor types. Assessment of tumour-associated necrosis provides prognostic information additional to World Health Organization/International Society of Urological Pathology grading for clear cell renal cell carcinoma. Fuhrman grading of renal cell carcinoma focuses on features of nuclear size, nuclear shape, and nucleolar prominence. Grade is assigned based on the highest grade present. And within a stage, an earlier letter (or number) means a lower stage.
