Serum CA125, CA199 and CEA Combined Detection for Epithelial Ovarian Cancer Diagnosis: A Meta-analysis

OBJECTIVE To evaluate the diagnostic value of combination detection of serum cancer antigen 125 (CA125), carbohydrate antigen 19-9 (CA199) and carci noembryonic antigen(CEA) in patients with epithelial ovarian cancer by pooling the open published studies according to meta-analysis method. METHODS Diagnostic studies related to combination detection of serum CA125, CA199 and CEA in patients with epithelial ovarian cancer were electronic searched in the databases of PubMed, Cochrane, Google scholar, EMBASE, ISI Web of Knowledge and CNKI by two independent reviewers. The combined diagnostic sensitivity, specificity, positive likely hood ratio (+LR), negative likely hood ratio (-LR), diagnostic odds ratio (DOR), and area under the receiver operating characteristic curve (AUC) were pooled by Med DiSc1.4 software. RESULTS Twelve prospective diagnostic publications were finally fulfilled the inclusion criteria and were included in this meta-analysis. The pooled diagnostic sensitivity specificity, positive likely hood ratio, negative likely hood ratio, diagnostic odds ratio, and AUC were 0.90 (95%CI: 0.80 to 0.92), 0.83 (95%CI: 0.80 to 0.86), 5.35(95%CI:3.90 to 7.33), 0.13 (95%CI: 0.10 to 0.16), 48.53 (95%CI: 29.91 to 78.72) and 0.92 (95%C: 0.89 to 0.94) respectively by fixed or random effect model. No publication bias was found according to the funnel plot and line regression test (t=-1.34, P=0.21). CONCLUSION Combination detection serum CA125, CA199 and CEA was a promising biomarker forepithelial ovarian cancer diagnosis with relative high sensitivity and specificity.
