Although the aromatase inhibitor anastrozole has been shown to be very effective in the treatment of hormone-dependent postmenopausal breast cancer, some patients with advanced disease will develop resistance to treatment. To investigate therapeutic strategies to overcome resistance to anastrozole treatment, we have used an intratumoral aromatase model that simulates postmenopausal breast cance...

BACKGROUND Endocrine therapy is one of the standard treatments for estrogen-receptor-positive breast cancer patients. Letrozole is the only aromatase inhibitor (AI) included in Thailand's essential drug list since the change of reimbursement policy in 2008, when patients had to change their AIs (other than letrozole) to letrozole. This study aimed to prove that the efficacy of anastrozole plus ...
PURPOSE In the Anastrozole, Tamoxifen Alone or in Combination trial, the combination arm was inferior to anastrozole alone in terms of disease-free survival possibly due to an adverse pharmacokinetic interaction or a predominant estrogenic effect of tamoxifen under estrogen deprivation. We assessed whether the addition of a lower dose of tamoxifen influenced anastrozole bioavailability and favo...
PURPOSE Multiple studies have shown that adherence to adjuvant hormonal therapy in women with breast cancer is suboptimal. Measurements of compliance with self-report, pill counts, and/or pharmacy records are susceptible to bias. We assessed the feasibility of using a urine anastrozole assay as an objective biomarker of nonadherence to anastrozole treatment. PATIENTS AND METHODS We recruited ...
BACKGROUND In the adjuvant setting, tamoxifen is the established treatment for postmenopausal women with hormone-sensitive breast cancer. However, it is associated with several side-effects including endometrial cancer and thromboembolic disorders. We aimed to compare the safety and efficacy outcomes of tamoxifen with those of anastrozole alone and the combination of anastrozole plus tamoxifen ...
PURPOSE To compare the efficacy of adjuvant anastrozole and letrozole in hormone receptor-positive postmenopausal patients with early breast cancer. METHODS A total of 569 hormone receptor-positive postmenopausal early breast cancer patients were included and analyzed in this study. Of them 238 were taking adjuvant anastrozole and 331 adjuvant letrozole. Demographic and medical data including...
Background Epidemiological studies have reported positive associations between anthropometric measures and risk for developing breast cancers that express hormone receptors and associated mortality. However, the impact of nutritional status on the molecular response to endocrine therapy has yet to be described. Methods Body mass index (BMI), waist circumference (WC), hip circumference (HP), a...
Tamoxifen and anastrozole are widely used as adjuvant treatment for early stage breast cancer, but their hepatotoxicity is not fully defined. We aimed to compare hepatotoxicity of anastrozole with tamoxifen in the adjuvant setting in postmenopausal breast cancer patients. Three hundred and fifty-three Chinese postmenopausal women with hormone receptor-positive early breast cancer were randomize...
