Relationship Between cmet, p53 Expression in Breast Carcinoma and Tumor Angiogenesis

ObjectiveTo find the role of oncogene cmet and suppressor gene p53 in the process of tumor angiogenesis and their clinical significance. MethodsBy immunohistochemical method and computer image analysis technique, microvessel count and cmet, p53 protein expression were quantitatively determined in 80 cases of breast carcinoma and 20 cases of breast fibroadenoma. ResultsThe high microvessel count and the positive expression of cmet, p53 were significantly correlated with histologic grade, lymph node metastasis and the stage of the tumor (P＜0.01). The high microvessel count was significantly correlated with the positive expression of cmet and p53 (P＜0.01).ConclusionBoth oncogene cmet and suppressor gene p53 modulate tumor angiogenesis of breast carcinoma.
