Prognostic scores have been developer for various cancers to provide a tool for patient stratification. Ultimately the application of a successful prognostic score should help the physician to plant he follow-up and decide on the use of adjuvant therapies.
Several prognostic systems have been proposed for patients with renal cell carcinoma (RCC). For resected localised or locoregional disease, the most widespread ones include the Stage, Size, Grade, and Necrosis (SSIGN), the University of California Los Angeles integrated staging system (UISS), and the Leibovich score (1-3).
All the above models for prognostication of port-operative survival for non-metastatic RCC are based on the TNM classification and evaluation of the tumour grade.
