Abstract
We investigated the expression of vascular endothelial growth factor (VEGF) in 175 colorectal carcinomas by immunohistochemistry. VEGF expression was correlated with advanced TNM stage (III, IV), advanced T stage (T3, T4), vessel involvement, lymph node metastasis, and liver metastasis. With regard to the prognosis, both overall and relapse-free survival was significantly poorer, and furthermore, the hematogenous recurrences were significantly more commonly found in the patients with VEGF-positive tumors. VEGF expresion in colorectal carcinomas may have a substantial value in predicting those patients at high risk for hematogenous recurrence after surgery.
