Contribution of catechol-O-methyltransferase Val158Met polymorphism to endometrial cancer risk in postmenopausal women: a meta-analysis
Catechol-O-methyltransferase (COMT) is a critical enzyme to detoxify the carcinogenic catechol estrogen and the Val158Met polymorphism of COMT could influence its enzymatic activity. Recent epidemiological studies have investigated the correlation of COMT Val158Met polymorphism with endometrial cancer risk; however, the results are inconsistent. To better evaluate the role of COMT Val158Met in endometrial carcinogenesis, we performed this meta-analysis, considering menopausal status, study quality, ethnicity, and source of controls.
