Adjuvant therapy for hormone receptor-positive breast cancer: Perspective from a survey on breast cancer physicians' acceptance of practice-changing data.

A cross-sectional online survey was conducted. A high proportion of the Chinese breast cancer (BC) physician respondents (n=77) would prescribe extended adjuvant endocrine therapy (AET) with aromatase inhibitors (AI) beyond 5 years for postmenopausal females with BC, especially those with higher risk. Respondents with ≥15 years of clinical experience were more likely to prescribe a longer duration of AET for low-risk patients.
