Endocrine therapy for breast cancer: assessing an array of women's treatment experiences and perceptions, their perceived self-efficacy and nonadherence.

Background: Although adjuvant endocrine therapy effectively prevents breast cancer recurrence, nonadherence rates are substantial. We therefore examined associations of women's experiences and perceptions regarding the efficacy, side effects, and practical problems of endocrine therapy with nonadherence. Furthermore, we examined whether women's perceived self-efficacy moderated these associations.

Trade-off preferences regarding adjuvant endocrine therapy among women with estrogen receptor-positive breast cancer.

Background: There is substantial nonadherence to effective adjuvant endocrine therapy for breast cancer prevention. We therefore examined patients' trade-offs between the efficacy, side-effects, and regimen duration, and whether trade-offs predicted nonadherence.

Patients And Methods: Trade-offs from 241 women were assessed with an Adaptive Conjoint Analysis (ACA) choice task that was customized to each individual patient.
