Abstract

The objective of this study was to perform a systematic review of the correlations between the single nucleotide polymorphism rs4680 in the catechol-O-methyltransferase (COMT) gene and susceptibility to ovarian cancer. A computer search was carried out for relevant case-control studies published between January 2000 to January 2014 in databases such as Ovid, EBSCO, PubMed, CNKI, CBMDISC, VIP, and WanFang Data. The literature was screened based on inclusion and exclusion criteria. A meta-analysis was performed by calculating the combined odds ratios (OR) and 95% confidence intervals (CI) using the RevMan 5.0. A total of 7 case-control studies were selected, which included 1439 cases and 2927 control subjects. Meta-analysis showed that the rs4680 polymorphism was not associated with ovarian cancer [GG vs (GA+AA): OR = 1.02, 95%CI = 0.88-1.19; G vs A allele: OR = 1.0, 95%CI = 0.90-1.11]. We, therefore, conclude that the COMT rs4680 polymorphism is not associated with susceptibility to ovarian cancer.
