【Abstract】Objective To evaluate the status of vascular endothelial growth factor (VEGF) expression in breast carcinoma and benign disease and define the relationship with age,menopause, tumor size，clinical stage，distant metastasis and lymph node metastasis. Methods Seventy cases of invasive ductal breast carcinomas,30 benign breast diseases and 7 adjacent nonneoplastic specimens were assessed for VEGF protein expression by immunohistochemistry LSAB method. Results VEGF were expressed more frequently in breast cancer than in benign diseases.VEGF was significantly correlated with axillary lymph node metastasis and distant metastasis,whereas no statistical correlation with other factors. Conclusion VEGF status has certain value to make differential diagnosis between malignant and benign breast diseases and predict the possibilities of distant and lymph node metastasis.
