CURRENT TNM CLASSIFICATION OF RENAL CELL CARCINOMA EVALUATED: REVISING STAGE T3a

Abstract

: We suggest revising the current pT3a classification based on perirenal fat infiltration but rendering a modified pT1/pT2 classification, which resolves pT3a cases without the loss of prognostic validity. Perirenal fat infiltration should not be used to assign T category. Tumors directly infiltrating the adrenal gland should be reclassified as T4.
