Association of CYP2C19 gene polymorphism with anastrozole in treatment of postmenopausal breast can-cer patients / 实用医学杂志

ABSTRACT

Objective To investigate the correlation between CYP2C19*2 gene polymorphism and efficacy of anastrozole in postmenopausal women with breast cancer. Methods The polymorphisms of CYP2C19*2 gene in postmenopausal women with postmenopausal breast cancer were detected by PCR. Results The A allele frequency of the CYP2C19*2 gene(OR=3.146,95% CI1.244~7.275,P<0.05)was a risk factor for the efficacy of post-menopausal breast cancer patients.The survival rate was lower than that of GG(χ2=6.26,P<0.05).After treat-ment,the FSH and LH of GG patients were significantly lower than those of AA and GA(t=5.29,6.47,P<0.05). Multivariate logistic regression analysis showed that anastrozoleand CYP2C19*2 gene polymorphism were indepen-dently associated with serum FSH and LH levels in postmenopausal women with breast. Conclusion CYP2C19*2 gene polymorphism is associated with anastrozole in the treatment of postmenopausal breast cancer.
