PROGNOSTIC ROLE OF FUHRMAN GRADE AND VASCULAR ENDOTHELIAL GROWTH FACTOR IN pT1a CLEAR CELL CARCINOMA IN PARTIAL NEPHRECTOMY SPECIMENS

Our study shows that recurrence and death are possible even in patients with small renal tumors. MVD, VEGF and Flk-1 expression do not depend on tumor size in pT1a RCC. Therefore, to date Fuhrman grading appears to be the only factor predictive of survival even in small RCC. Thus, Fuhrman grading is predictive of mortality. While VEGF is not predictive of survival as a single parameter, based on its percent of expression (lower or higher than 25%) it can determine 2 groups that are different from the prognostic point of view.
