[New approaches to the classification, grading, and prognosis of renal cell carcinoma].

Renal cell carcinoma is a heterogeneous group of tumors. Frequent revisions of its histological classification and TNM staging system complicate the retrospective studies of large patient groups and hamper the estimation of survival rates and quality of life for patients. Due to improving therapeutic possibilities, the problems of the staging, morphological diagnosis, grading, and determination of prognostic factors of renal cell carcinomas have assumed a particular significance. Despite the long-term history of studies dealing with renal cell carcinoma, there is no general agreement among specialists at to these issues. The paper reviews the recent International Society of Urological Pathology Consensus held in Vancouver in March 2013.
