摘要:目的检测S100A7蛋白和CD34蛋白在基底细胞样乳腺癌中的表达情况,分析S100A7与基底细胞样乳腺癌临床病理特征之间的关系及其与CD34标记的微血管密度(MVD)值之间的关系,探讨S100A7在基底细胞样乳腺癌血管生成和侵袭转移中的作用。方法采用免疫组织化学二步法检测60例基底细胞样乳腺癌、40例非基底细胞样乳腺癌、20例正常乳腺组织中S100A7和CD34的表达情况。结果S100A7在基底细胞样乳腺癌、非基底细胞样乳腺癌及正常乳腺组织中的表达率分别为83.33%、62.50%、35.00%,差异有统计学意义(χ2=5.556,P<0.05; χ2=17.107,P<0.05; χ2=4.051,P<0.05)。S100A7与基底细胞样乳腺癌患者的淋巴结转移、TNM分期及MVD值呈正相关,而与患者的年龄、肿瘤大小无明显相关性。结论S100A7的表达上调可能与基底细胞样乳腺癌的发生发展、侵袭转移及血管形成过程有关。S100A7促进血管的生成的作用可能是其促进肿瘤的局部侵袭和远处转移的重要因素。

Abstract:ObjectiveTo detect the protein expressions of S100A7 and CD34 in basallike breast carcinoma and analyze the clinical relationship between S100A7 and basallike breast cancer and the connection with CD34 markers microvessel denisity (MVD). To study the function of S100A7 in basallike breast cancer angiogenesis, invasion and metastasis. MethodsImmunohistochemistry (IHC) was used to detect the expressions of S100A7 and CD34 in 60 cases of basallike breast cancer, 40 cases of non basallike breast cancer and 20 cases of normal breast tissues. ResultsThe expressions of S100A7 in basallike breast cancer, non basallike breast cancer and normal breast tissues were 83.33%, 62.50% and 35.00% respectively. There were significant differences among them (χ2=5.556, P<0.05l; χ2=17.107, P<0.05; χ2=4.051, P<0.05). There was positive correlation between S100A7 and lymph node metastasis, TNM staging and MVD of basallike breast cancer patients. But there was no significant correlation between S100A7 and patient′s age and tumor sizes. ConclusionThe upregulation of S100A7 expressions may be associated with the occurrence and development, invasion and metastasis, angiogenesis of basallike breast cancer. The effects of S100A7 promoting angiogenesis may be an important factor in the acceleration of the local invasion and distant metastasis in basallike breast cancer.
