Potential Role of MicroRNA-375 as Biomarker in Human Cancers Detection: A Meta-Analysis

Abstract EN

The association between circulating microRNA-375 (miR-375) expression and cancers has been studied; however, the results are inconsistent.

We searched PubMed, Embase, and Web of Science for studies concerning the diagnostic value of miR-375 for cancer.

The bivariate meta-analysis model was employed to summarize sensitivity, specificity, and diagnostic odds ratio (DOR) for miR-375 in the diagnosis of cancer.

Summary receiver operating characteristic (SROC) curve analysis and the area under the curve (AUC) were also used to check the overall test performance.

A total of 645 cancer patients and 421 cancer-free individuals from 12 studies were contained in this meta-analysis.

The summary estimates revealed that the pooled sensitivity was 78% (95% confidence interval (CI): 64%–87%), the specificity was 74% (95% CI: 62%–84%), the DOR was 10.04 (95% CI: 6.01–16.77), and the AUC was 0.82 (95% CI: 0.79–0.85).

In addition, we found that the diagnostic effect of miR-375 varies according to the race and cancer type.

Our data suggest that miR-375 profiling has a potential to be used as a screening test for cancers but the specific race and cancer should be considered.

More studies on the diagnostic value of miR-375 for cancer are needed in the future.
