Abstract:

Objective

To evaluate the diagnostic value of sputum miRNA-21 in lung cancer and provide evidence for the clinical diagnosis and treatment of this malignancy.

Methods

The PubMed, Cochrane Library, Embase, CNKI, SinoMed, VIP, and Wanfangdata databases were searched for relevant articles, which were then selected according to the inclusion and exclusion criteria. Stata and MetaDiSc were used for Meta-analysis.

Results

Four articles including five studies of diagnostic value of sputum miRNA-21 in lung cancer were used for this Meta-analysis. The results showed that the pooled sensitivity was 0.72 (95%CI: 0.66-0.78), the pooled specificity was 0.77 (95%CI: 0.71-0.82), the pooled diagnostic odds ratio was 8.71 (95%CI: 5.46-13.89), and the area under the summary receiver operating characteristic curve was 0.8263.

Conclusion

MiRNA-21 in sputum is of high value in the diagnosis of lung cancer. Limited by the number and quality of the included studies, there still needs more clinical trials to verify our findings.
