Objective To investigate the relation of vascular endothelial growth factor (VEGF) and angiogenesis to the progression of colorectal carcinoma (CC). Methods VEGF protein expression and microvessel density (MVD) in 102 cases of human CC were examined by use of immunohistochemical staining. MVD and VEGF expression were analysed with their relation to histological grade, depth of invasion, Dukes stage, lymph node metastasis, liver metastasis and prognosis of CC. Results MVD was significantly higher in VEGF positive CC than in VEGF negative CC ( P

ObjectiveTo determine the prognostic value of angiogenesis in non-metastatic colorectal carcinoma at the time of laparotomy.Methods Microvessel counts(MVC) of 58 specimens were investigated by immunohistological staining with a monoclonal antibody against F-Ⅷ RAg. Correlation between MVC, clinicopathologic factors, postoperative local recurrence, and liver metastasis was evaluated.Results MVC correlated positively with postoperative local recurrence(P21, the risk of liver metastasis and local recurrence significantly increased. MVC also correlated with prognosis (P
