Abstract:
[Abstract] Objective: To determine the potential diagnostic value of miRNA-29 (miR-29) for malignant tumor. Methods: A systematic search of literature regarding miR-29 was performed in three English databases (PubMed, Web of Science, and Embase) and two Chinese databases (Chinese National Knowledge Infrastructure [CNKI] and WanFang). The retrieval was ended until September 15,2018. Search terms included miRNA-29 (miR-29), tumor, cancer, serum, plasma, diagnosis, etc. Quality Assessment of Diagnostic Accuracy Studies-2 (QUADAS-2) was carried out to evaluate the quality of the selected articles. STATA12.0 was used to calculate the combined sensitivity, specificity, positive likelihood ratio (PLR), negative likelihood ratio (NLR) and diagnostic odds ratio (DOR). Subgroup analysis and Meta-regression analysis were carried out to explore the origin of heterogeneity. Results: Twenty eligible articles were selected from 1 172 literatures related to tumors and miR-29. The combined sensitivity was 0.76 (95%CI: 0.68-0.83), combined specificity was 0.83 (95%CI: 0.74-0.89), combined PLR was 4.5 (95%CI: 2.7-7.4), combined NLR was 0.28 (95%CI: 0.20-0.41), DOR was 16 (95%CI: 7-35), and the AUC was 0.86 (95%CI: 0.83-0.89). The combined specificity of plasma samples was higher than that of serum samples, and the difference was statistically significant (P<0.01). There was a higher diagnostic value of miR-29 for breast cancer and pancreatic cancer (DOR=101.52, 11.22), but lower diagnostic value for colorectal cancer and non-small cell lung cancer (DOR=5.05, 6.57); miR-29b showed a high diagnostic value for cancer (DOR=60.91). The publication bias was not obvious in this study (P>0.05). Conclusion: This systematic review and Meta-analysis suggests that miR-29 family is a potential biomarker in the diagnosis of cancers with great sensitivity and specificity.
