ABSTRACT=<p><bold>Objective:</bold> Melanoma is the most aggressive and deadly form of skin cancer, especially at later stages. There is currently no excellent diagnostic test established for the diagnosis of melanoma; however, circulating microRNAs (miRNAs) have shown some promise. We seek to conduct a systematic review and meta-analysis to establish the clinical utility of circulating miRNAs in diagnosing melanoma.</p><p><bold>Methods:</bold> PubMed, Wiley, and Web of Science were searched for studies that determined miRNA sensitivity and specificity in patients with melanoma. The included studies were assessed in Stata, and the sensitivity, specificity, summary receiver operating characteristic (SROC), positive likelihood ratio, negative likelihood ratio, and the area under the SROC curve (AUC) were calculated.</p><p><bold>Results:</bold> 9 studies with 898 melanoma patients were included in the meta-analysis. The circulating miRNAs showed high diagnostic accuracy with a sensitivity of 0.89 (<italic>p</italic> &lt; 0.001), specificity of 0.85 (<italic>p</italic> &lt; 0.001), diagnostic odds ratio of 45, and an area under the curve of 0.93.</p><p><bold>Conclusion:</bold> Circulating miRNAs have shown a high diagnostic power in detecting melanoma.</p>
