Could microRNA be used as a diagnostic tool for lung cancer?

Current methods for diagnosing lung cancer (LC) have varying degrees of risks and complications. MicroRNA (miRNA) is a small molecule noncoding RNA with gene regulation functions. Many studies have shown that miRNA can be used for the diagnosis of LC, but there are differences in diagnostic accuracy. Therefore, we aim to systematically review and meta‐analyze published articles to comprehensively evaluate the diagnostic value of miRNA for LC.
