摘要
目的:探讨miR-141、miR-145作为非小细胞肺癌(non-small cell lung cancer,NSCLC)生物标志物的诊断价值。方法:采用实时荧光定量PCR技术检测80例正常人和80例非小细胞肺癌患者血清中miR-141、miR-145的表达量,分析miR-141、miR-145的表达与非小细胞肺癌临床病理参数的关系,并绘制ROC曲线分析其诊断非小细胞肺癌的价值。结果:非小细胞肺癌患者miR-141、miR-145表达与对照组比较有统计学差异(P〈0.05),二者联合的诊断效能分别为:灵敏度92%(95%CI:0.86~0.96),特异度83%,(95%CI:0.73~0.88),阳性预测值(PPV)86%,阴性预测值(NPV)92%。结论:血清中miR-141、miR-145测定的诊断性能较高,可以作为非小细胞肺癌的潜在的诊断标志物。
Objective: To evaluate the value of expression of serum miR-141 and miR-145 in the diagnosis of non-small cell lung cancer( NSCLC). Methods: Serum miR-141 and miR-145 level were measured by real time-PCR. 160 samples were divided into two sets 80 patients with NSCLC,80 healthy volunteers. sensitivity,specificity,positive predictive value( PPV) and negative predictive value( NPV). Results: In training set,the expression of miR-141 and miR-145 were significant different compared to the control group. In the test set,the diagnostic values of miR-141 and miR-145 were as follow: sensitivity 92%( 95% CI: 0. 86 ~ 0. 96),specificity 83%( 95% CI: 0. 73 ~0. 88),PPV86% and NPV 92%. Conclusion: Serum miR-141 and miR-145 can be used as early biomarkers for NSCLC.
