摘要：

目的:探讨miRNA-221在非小细胞肺癌组织中的表达及其与预后的相关性。方法:回顾性收集分析南通大学附属医院2010年1月至2012年12月期间行完全切除术治疗的153例非小细胞肺癌患者的临床资料,同时应用RT-PCR检测患者组织标本miRNA-221的表达量,分析其与患者临床资料及总生存期(OS)的关系。结果:年龄、临床分期与miRNA-221表达存在相关性,P<0.05。单因素COX回归分析显示, 临床分期(OR=1.96,95%CI:1.14~2.67)、腺癌(OR=2.54,95%CI:1.77~5.12)、肿瘤大小(OR=1.33,95%CI:1.01~2.14)和miRNA-221(OR=3.07,95%CI:1.76~6.31)表达均是影响OS的危险因素;多因素COX回归分析显示,临床分期(OR=3.32,95%CI:1.67~7.05)和miRNA-221表达(OR=2.55,95%CI:1.41~4.85)是影响OS的独立危险因素。结论:miRNA-221高表达提示非小细胞肺癌患者OS较短,有望作为肺癌预后预测的分子标志物。

Objective:To investigate the expression of miRNA-221 in non-small cell lung cancer and its correlation with prognosis. Methods:the clinical data of 153 patients from January 2010 to December 2012 with non-small cell lung cancer who were treated by surgery were retrospectively analyzed, and the expression of miRNA-221 was detected by RT-PCR analysis, and the relationship between the clinical data and the overall survival(OS) of patients was analyzed. Results:there was a correlation between age, clinical stage and miRNA-221 expression with P<0.05. COX regression analysis showed that clinical staging (OR=1.96, 95%CI:1.14-2.67), adenocarcinoma (OR=2.54, 95%CI:1.77-5.12), tumor size (OR=1.33, 95%CI:1.01-2.14) and miRNA-221 expression (OR=3.07, 95%CI:1.76-6.31) were the risk factors of OS, clinical stage (OR=3.32, 95%CI:1.67-7.05) and miRNA-221 expression (OR=2.55, 95%CI:1.41-4.85) were independent risk factors of OS. Conclusion:miRNA-221 highly expresses in the short-lived patients with non-small cell lung cancer, and may be expected to be a molecular marker for predicting the prognosis of lung cancer.
