| Summary: | Non-small-cell lung cancer (NSCLC) is a major subtype of lung cancer, accompanied by dismal prognosis. Recent studies have reported microRNAs (miRNAs) may act as diagnosis biomarkers in NSCLC. This network meta-analysis was performed toidentify miRNA and their potential diagnostic value for NSCLC systematically. Several databases were recruited for eligible studies, and the retrieval spectrum ranged from the inception to June 2018. Besides, 142 NSCLC patients and 168 patients with benign lung disease were enrolled. Direct and indirect evidence were incorporated to evaluate weighted mean difference (WMD) and ranking probability (RP) based on surface under the cumulative ranking curves (SUCRAs). The expressions of miRNAs were further validated by RT-qPCR. The sensitivity, specificity, and receiver operator characteristic (ROC) curve were used to evaluate diagnostic performance. The expression of miR-192 and miR-17 was lower than that of miR-21 in plasma samples of NSCLC. However, the expression of miR-16, miR-34a and miR-1-5p was lower while the levels of let-7g and mR-218-5p were higher than that of miR-21 in NSCLC tissues. miR-21 and let-7g levels were upregulated in plasma/tissues of NSCLS, but miR-16, miR-34a, let-7b-5p and miR-218-5p expression wasdownregulated. In the analysis of ROC curve, let-7g (sensitivity: 0.901; specificity: 0.893) and miR-218-5p (0.817, 0.964) in plasma as well as miR-16 (0.915, 0.964), miR-34a (0817, 0.964) and miR-218-5p (0.831, 0.964) in tissues revealed higher diagnostic value for NSCLC. It demonstrates that let-7g/miR-218-5p in plasma and miR-16/miR-34a/miR-218-5p in tissues can potentially be used as diagnostic biomarkers of NSCLC. |
