A meta-analysis of serum cancer antigen 125 array for diagnosis of ovarian cancer in Chinese

Objective: To further evaluation the diagnosis accuracy of serum cancer antigen 125 (CA125) in the diagnosis of ovarian cancer in Chinese patients. Materials and Methods: The PubMed, Wanfang and CNKI databases were electric searched and relevant diagnosis trials were reviewed and finally included in this meta-analysis. The diagnosis sensitivity, specificity, positive likely hood ratio (+LR), negative likely hood ratio ( LA), diagnostic odds ratio (DOR) and receiver operating characteristic curve were pooled by Meta DiSc 1.4 software. Results: Nineteen studies with a total of 2426 subjects were included in this meta-analysis. The pooled sensitivity, specificity, +LR, LA and DOA were 0.75 (95% confidence interval = 0.73-0.78), 0.80 (0.77-0.82), 4.52 (3.27-6.26), 0.31 (0.28-0.35) and 15.76 (10.45-23.75) respectively. The area under the summary receiver operating characteristic curve was 0.84. Conclusion: Serum CA125 was potential biomarker for diagnosis of ovarian cancer with acceptable diagnosis value.
