Evaluation of the Prognostic Significance of Microvessel Count and Tumor Size in Renal Cell Carcinoma

Abstract

Tumor size cannot be readily justified as a determinant of prognosis in patients with medium- or large-sized tumors. In patients with low-stage tumors, microvessel count served as the only significant determinant for prognosis. When the patients were considered as a whole, microvessel count, M criteria, macrovenous invasion and histological grade were significant prognostic factors.
