Abstract:
The most important prognostic parameter in renal cell carcinoma is tumor stage. Although pathologic primary tumor (pT) categories are influenced by tumor size (pT1-pT2), critical elements (≥pT3) are dictated by invasion of structures, including renal sinus, perinephric fat, and the renal vein or segmental branches. Because this invasion can be subtle, awareness of the unique characteristics of renal cell carcinoma is critical for the pathologist to aid in clinical decision making. This review addresses challenges in pathologic stage and grade reporting and updates to the World Health Organization and American Joint Commission on Cancer classification schemes.
