摘要
目的探讨Delta样配体4(DLL4)、环氧合酶-2(COX-2)和基质金属蛋白酶-2(MMP-2)在不同乳腺癌分子亚型组织中的表达情况及意义。方法采用免疫组化SP法检测乳腺癌(Luminal A型41例,Luminal B型18例,HER-2过表达型22例,基底细胞样型19例)组织100例及癌旁组织40例中DLL4、COX-2和MMP-2的表达情况,并分析三者表达及与淋巴结转移的相关性。结果 DLL4、COX-2和MMP-2在乳腺癌组织中的阳性表达率分别为73.0%、81.0%和93.0%,均明显高于癌旁组织(P<0.05)。在不同分子亚型乳腺癌组织中,DLL4、COX-2和MMP-2在HER-2过表达型乳腺癌组织中的阳性表达率分别为95.5%、100.0%和100.0%,在基底细胞样型乳腺癌组织中分别为89.5%、94.7%和100.0%,均高于Luminal A型和Luminal B型乳腺癌组织(P<0.05)。DLL4、COX-2和MMP-2在有淋巴结转移的乳腺癌组织中阳性表达率分别为88.7%、92.5%和96.2%,显著高于无淋巴结转移者的阳性表达率(P<0.05)。DLL4分别与COX-2、MMP-2表达呈正相关(r=0.215,P<0.05;r=0.435,P<0.05)。结论 DLL4、COX-2和MMP-2在基底细胞样型和HER-2过表达型乳腺癌组织中呈高表达,DLL4、COX-2和MMP-2共同参与乳腺癌的发生、发展及浸润转移,联合检测三者表达可评估乳腺癌的转移情况。
