Objective: To study the expression and significance of VEGF-C, D2-40, and E-Cad in Human breast carcinoma. Methods: S-P immunohistochemical method was used to assess the expression of VEGF-C in 88 cases of infiltrating ductal carcinoma of the breast (with intact clinicopathologic and follow-up in-formation) and 54 cases of different intraductal hyperplastic lesions. The relationship of VEGF-C expression with D2-40 and E-Cadherin in infiltrating ductal carcinoma of the breast was analyzed. Results: VEGF-C ex-pression was higher in the invasive group than that in the dysplasia group and benign lesions. VEGF-C ex-pression in the metastatic group was significantly higher than that in the group without lymph node metasta-sis, indicating that VEGF-C plays an important role in the growth and metastasis of breast cancer. VEGF ex-pression in breast cancer group was higher than that in the dysplasia group and benign lesions. LVD count in the group with lymph node metastasis was significantly higher than that in the group without lymph node me-tastasis. The positive rate of E-Cad expression in the invasive group was significantly lower than that in the dysplasia group and benign lesions. VEGF-C expression was positively correlated with D2-40 expression. VEGF-C expression was negatively correlated with E-Cad expression. Conclusion: VEGF-C and D2-40 could be used for the detection of early lymphatic metastasis of breast cancer. VEGF-C and E-Cad can be used as important indices for the evaluation of the prognosis of breast cancer.
