Abstract:

目的研究P21ras、CD44v6、骨桥蛋白(OPN)在肺鳞癌和腺癌中的表达及其与肺鳞癌和腺癌预后的相互关系。方法应用免疫组化方法对96例非小细胞肺癌患者分别检测P21ras蛋白、CD44v6、OPN的表达,分析P21ras蛋白、CD44v6、OPN与肺癌组织学类型、分化程度、TNM分期等的关系,并通过34例随访病例了解以上指标与肺癌预后的关系。结果⑴中OPN及CD44v6在鳞癌中表达率高于腺癌,而P21ras蛋白则在鳞癌及腺癌间表达差异无统计学意义,但P21ras蛋白、CD44v6、OPN三者共同表达在鳞癌则高于腺癌;(2)晚期肺癌P21ras蛋白、CD44v6、OPN的阳性表达率均显著高于早期患者,而CD44v6及OPN则在淋巴结已有转移者阳性表达率显著高于无淋巴结转移者;(3)P21ras蛋白、CD44v6、OPN阳性组累积生存率低于阴性组。结论P21ras蛋白、CD44v6、OPN在鳞癌三者共同高表达,三者共同作用可能与肺鳞癌的发生、发展密切相关,P21ras蛋白、CD44v6、OPN的阳性表达预示着非小细胞肺癌不良预后。
