摘要: Aim: This study tested for associations between SLCO1B1 polymorphisms and circulating estrogen levels in women with breast cancer treated letrozole or exemestane. Patients & methods: Postmenopausal hormone-receptor positive were genotyped SLCO1B1*5 (rs4149056) rs10841753. Pretreatment on-treatment plasma estrogens aromatase inhibitor (AI) concentrations measured. Regression analyses performed to test pharmacogenetic drug concentrations. Results: was associated elevated pretreatment estrone sulfate an increased risk of detectable after 3 months AI treatment. Conclusion: These findings suggest may have effect on estrogenic response treatment, therefore adversely impact the anticancer effectiveness these agents.
