In summary, this meta-analysis suggests that Leu432Val polymorphism is associated with ovarian cancer, lung cancer, and endometrial cancer risk; Asn453Ser and Arg48Gly polymorphisms are associated with endometrial cancer risk among Caucasians, Ala119Ser polymorphism is associated with prostate cancer risk, and Ala119Ser polymorphism is associated with breast cancer risk in Caucasians.
The CYP1B1 and ERalpha genes may play a role in endometrial cancer and the Arg48Gly (142C > G) -CYP1B1 and 975C > G-ERalpha polymorphisms may be considered as independent, early diagnostic markers in this disease.
An association of CYP1B1 gene R48G polymorphism with endometrial cancer was found [GG vs. GC+CC: odds ratio (OR)=0.55, 95% confidence interval (CI): 0.42-0.73, P<0.0001; GG vs. CC: OR=0.46, 95% CI: 0.23-0.91, P=0.03].
