Answer

Tumor stage is the key prognostic parameter in renal cell carcinoma (RCC). [1] The grading schema of renal cell carcinoma (RCC) is based on the microscopic morphology of a neoplasm with hematoxylin and eosin (H&E) staining. The most popular and used widely system for grading renal cell carcinoma (RCC) has been a nuclear grading system described in 1982 by Fuhrman et al, [2]  which concurrently evaluates nuclear size and shape, and nucleolar prominence. [3] However, discordance and grading imprecision may occur among these three parameters, rendering the Fuhrman grading inapplicable. [3]
