摘要 目的为了寻找适当的能反映喉癌浸润转移的肿瘤标志物,研究能够降解细胞外基质的膜型-Ⅰ型基质金属蛋白酶(M T 1-MM P)蛋白在人喉鳞癌中的定位及其量的表达的临床意义。方法采用免疫组化方法对50例喉鳞癌患者的50个原发灶,34个癌旁组织,22个转移的淋巴结,20个正常黏膜标本中的膜型-Ⅰ型基质金属蛋白酶蛋白进行检测,采用图像分析对其进行定量分析,并统计分析其与肿瘤的分期、淋巴结转移等临床病理参数的关系。结果原发灶中M T 1-MM P蛋白主要在肿瘤细胞的胞浆和胞膜中呈强阳性表达,进展期肿瘤的癌巢周边的基质细胞(成纤维细胞及成纤维样细胞等)中呈弱阳性表达。M T 1-MM P蛋白的表达与淋巴结转移、术后的复发有关(P=0.000),对有淋巴结转移的正确预测值为95.5%,无淋巴结转移的正确预测值为60.7%。结论M T 1-MM P蛋白主要在肿瘤细胞的胞浆和胞膜中表达,其高表达与喉癌淋巴结转移与复发有关,是预测其早期浸润转移的一个较好的指标。
