Prognostic Significance of Venous Thrombus in Renal Cell Carcinoma. Are Renal Vein and Inferior Vena Cava Involvement Different?

Abstract

For patients with pT3b disease, local tumor stage and grade are better predictors of prognosis than extent of venous involvement. Based on our data we support the current TNM classification of venous involvement with RV and IVC invasion categorized as T3b and IVC involvement above the diaphragm categorized as T3c.
