目的:探讨cortactin(皮层肌动蛋白)在非小细胞肺癌(non-smallcelllungcancer,NSCLC)组织中的表达及与临床病理因素之间的关系。方法:采用免疫组织化学SP法检测117例NSCLC及相应癌旁正常肺组织中cortactin的表达情况。结果:cortactin在正常肺组织中阳性表达率为19.7%(23/117),在NSCLC组织中的阳性率为59.0%(69/117),二者比较具有显著性差异(P〈0.001)。cortactin的表达与NSCLC的临床分期(P=0.006)及淋巴结转移(P:0.003)正相关,与其它临床病理因素无关(P〉0.05)。结论:cortactin在肺癌组织中的表达显著高于正常肺组织,其高表达与淋巴结转移及临床分期相关。cortactin的高表达可能是促进NSCLC进展的因素之一。
Objective:To investigate the expression of cortactin in non- small cell lung cancer (NSCLC) and its correlation with clinicopathological factors. Methods:The expression of cortactin in 117 NSCLC specimens and adja- cent normal tissues was detected by immunohistochemical method. Results: The positive expression rate of cortactin inNSCLC was 59.0% (69/117) ,much higher than that in normal lung tissues ( 19.7% ,23/117) (P 〈 0. 001 ). The expression of eortaetin was positively eorre!ated with lymph node metastasis ( P = 0.003 ) and TNM stage ( P = 0.006 ). There was no statistically significant eorrelation between eortaetin expression and other elinieopathologieal factors. Conclusion:Increased eortaetin expression in NSCLC was associated with lymph node metastasis and advanced TNM stage. The expression of eortaetin may play a role in tumor progression of NSCLC.
