Collecting System Invasion and Fuhrman Grade But Not Tumor Size Facilitate Prognostic Stratification of Patients With pT2 Renal Cell Carcinoma

Tumor size did not have a significant influence on cancer specific survival in pT2 tumors, neither continuously applied nor based on various cutoff values. To enhance prognostic discrimination, multifactorial staging systems including pathological features should be implemented. The prognostic relevance of the variable subsuming Fuhrman grade and collecting system invasion should be considered for future evaluation.
