ABSTRACT
Objective:To investigate the expression of AEG-1 gene in NSCLC and its clinical significance. Methods:Selected our hospital cardiothoracic surgical resection of 83 cases of postoperative cancer tissues of NSCLC patients and 20 paracancer to study, immunohistochemical staining was used to detect the expression level of AEG-1 protein in two groups,the clinical and pathological of AEG-1 protein in patients with NSCLC was analyzed. Results:NSCLC tissues AEG-1 protein expression 46 cases ( 55. 42%) was sig-nificantly higher than 2 cases ( 10. 00%) of paracancer ( P0. 05 ) . AEG-1 high expression of NSCLC in patients with a median survival time of 15. 0 months was significantly lower than that of 19. 0 months (log-rankχ2=4. 119 P<0. 05,) in patients with low expression of AEG-1. Conclusion:AEG-1 gene expression has been up-regulated in NSCLC tissue,which was related to the clinical stage and distant metastasis of the patients.
