title: Histologic variants of renal cell carcinoma: does tumor type influence outcome?
abstract: Each histologic type of renal cell carcinoma (RCC) has different pathologic and clinical parameters; however, the independent role of histologic type in outcome prediction remains contested. Most studies show relevance for outcome of each histologic type when correlated with survival by univariate analysis, whereas few studies show differences in outcome once other key prognostic factors, such as stage and grade, are considered. These studies highlight the challenges to prove outcome relevance. Despite the contested independent value of type for outcome prediction, separation of RCC into types is well accepted and can be substantiated on clinical, pathologic, molecular, and general outcome differences.
