Objective: The purpose of this study was to assess the diagnostic sensitivity and specificity for serum pro-gastrin-releasing peptide (Pro-GRP) in diagnosis of small cell lung cancer (SCLC) through pooling all the open published data. Materials and Methods: Databases of PubMed, Cochrane, ISI Web of Knowledge, and CNKI were electronic, searched by two reviewers to find the diagnostic study serum Pro-GRP in diagnosis of SCLC. The diagnostic sensitivity, specificity, positive likelihood ratio (PLR), negative likelihood ratio (NLR), diagnostic odds ratio (DOR), and area under the receiver operating characteristic (ROC) were calculated by Med DiSc1.4 software. Results: Finally, 21 studies were included in this meta-analysis. Because of statistical heterogeneity, the specificity, specificity, positive/negative likelihood ratio, and DOR were pooled by random effect model. The pooled sensitivity, specificity, PLR, NLR, DOR, and area under the ROC were 64% (95% confidence interval [CI]: 62%–66%), 94% (95% CI: 94%–95%), 11.87% (95% CI: 8.62–11.35), 0.32% (95% CI: 0.26%–0.39%), 40.98% (95% CI: 27.77%–60.64%), and 0.94 (95% CI: 0.91%–0.96%). Conclusion: Serum Pro-GRP was promising biomarker for SCLC diagnosis.
