摘要 目的观察非小细胞肺癌(NSCLC)组织中CC类趋化因子受体7(CCR7)、哺乳动物雷帕霉素靶蛋白(mTOR)的表达变化,并探讨其临床意义。方法应用免疫组织化学染色(MaxVisionTM二步法)检测42例NSCLC患者癌组织中的CCR7、mTOR,分析其与NSCLC临床病理参数的关系。结果 NSCLC组织中,CCR7阳性表达率59.5%,mTOR阳性表达率为50.0%。CCR7表达与NSCLC患者的年龄、性别、TNM分期、病变部位及有无淋巴结转移无关(P均>0.05),但在腺癌中阳性表达率为82.6%(19/23),鳞状细胞癌为31.6%(6/19),P<0.01;在肿瘤直径≤3.0 cm者阳性表达率为82.4%(14/17),而>3.0 cm者仅为44.0%(11/25),P<0.05。mTOR表达与NSCLC患者的年龄、性别、病理类型、TNM分期、肿瘤大小、有无淋巴结转移及病变部位均无关(P均>0.05)。NSCLC组织中,CCR7与mTOR的表达呈正相关(r=0.340,P<0.05)。结论 NSCLC组织中均有CCR7、mTOR表达,且CCR7表达与病理类型和肿块大小有关,有助于鳞癌和腺癌的鉴别。
