Emerging evidence demonstrated that circular RNAs (circRNAs) were dysregulated in lung cancer, indicating that circRNAs might serve as novel diagnostic and prognostic biomarkers for lung cancer. However, the clinical value of circRNAs on lung cancer remains unclear. This study aimed to evaluate the efficiency of circRNAs in the diagnosis and prognosis for lung cancer in China. 2122 Chinese individuals were enrolled in this investigation for assessment of diagnostic value and examination of prognostic analysis. In the diagnostic analysis, the pooled sensitivity, specificity, PLR, NLR, DOR, and AUC of the sROC curve with their 95% CIs were 0.80 (95%CI: 0.74-0.84), 0.80 (95%CI: 0.73-0.86), 3.97 (95%CI: 2.80-5.62) and 0.26 (95%CI: 0.19-0.34), 15.51 (95%CI: 8.76-24.47), and 0.85 (95%CI: 0.82-0.88), respectively. As for the prognostic power of circRNAs, lung cancer patients with higher expression levels of circRNAs tend to possess lower overall survival with the overall pooled HR (1.70, 95%CI: 1.26-2.29). Furthermore, in stratified analysis, upregulated and downregulated circRNAs were manifested to exert significant effects on prognosis with HR values of 2.17 (95%CI: 1.74-2.72) and 0.52 (95%CI: 0.34-0.80). This study validates that circRNAs are promising diagnostic and predictive biomarkers for lung cancer patients in China.
越来越多的证据表明,环状 RNA(circRNA)在肺癌中失调,表明 circRNA 可能作为肺癌的新型诊断和预后生物标志物。然而,circRNA 对肺癌的临床价值尚不清楚。本研究旨在评估 circRNA 在中国人群中对肺癌的诊断和预后价值。共有 2122 名中国人参与了本研究,用于评估诊断价值和预后分析。在诊断分析中,汇总敏感性、特异性、PLR、NLR、DOR 和 sROC 曲线的 AUC(95%CI)分别为 0.80(95%CI:0.74-0.84)、0.80(95%CI:0.73-0.86)、3.97(95%CI:2.80-5.62)和 0.26(95%CI:0.19-0.34)、15.51(95%CI:8.76-24.47)和 0.85(95%CI:0.82-0.88)。至于 circRNA 的预后能力,circRNA 表达水平较高的肺癌患者总生存率较低,总合并 HR(1.70,95%CI:1.26-2.29)。此外,在分层分析中,上调和下调的 circRNA 对预后均有显著影响,HR 值分别为 2.17(95%CI:1.74-2.72)和 0.52(95%CI:0.34-0.80)。本研究验证了 circRNA 是中国肺癌患者有前途的诊断和预测生物标志物。
