ABSTRACT
Objective The 4-and 16-hydroxylated metabolites of estrogens have been implicated in carcinogenesis,whereas its 2-hydroxylated metabolites have been shown to have antiangiogenic effects.We aimed to examine whether the polymorphisms of catechol-O-methyltransferase(COMT)involved in the estrogen metabolism are associated with endometrial cancer risk.Methods Polymerase chain reaction- restrictive fragment length polymorphism(PCR-RFLP)analysis was used to study the variant allele frequency distributions of COMT Val158Met genetic polymorphism in a population based case-control study with 132 endometrial cancer cases and 110 controls.Odds ratios(OR)and 95% confidence intervals(CI) were estimated by unconditional logistic regression after adjustment for known or suspected risk factors for endometrial cancer.Results The most frequent genotype was COMT~(Val/Val)(47.2%,52/110)in control group and COMT~(Mal/Met)(58.3%,77/132)in endometrial cancer group.The difference between the two groups was of statistical significance(P
