乳腺疾病中血管内皮生长因子的表达及其意义

目的 观察乳腺良恶性疾病中血管内皮生长因子（VEGF）的表达状况以及与肿瘤大小、临床分期、血行转移、腋淋巴结转移等预后因素的关系。方法 用免疫组化LSAB法分析了70例乳腺浸润性导管癌、30例良性乳腺病和7例癌旁组织中VEGF的蛋白表达情况。结果 乳癌组和癌旁组VEGF表达水平显著高于良性病组。有血行转移或淋巴结转移组VEGF表达水平高于无转移组，而在其他预后因素中分布无差异。结论 VEGF表达水平对判定乳腺疾病良恶性及乳癌血行转移或淋巴转移的可能性有一定的预示价值。

EXPRESSION OF VASCULAR ENDOTHELIAL GROWTH FACTOR IN BREAST DISEASES AND ITS IMPLICATION

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 non neoplastic 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.
