Oncologist briefing given by Dr. Castel as Principal Investigator of the Breast Cancer Adjuvant Therapy prospective longitudinal study (NCT00954564) to communicate interim results and help oncologists identify and refer eligible breast cancer patients into the longitudinal cohort study. The goal of this presentation was to help achieve study enrollment targets.

2. Aims of the prospective cohort
Among women with early breast cancer initiating adjuvant endocrine therapy with an
aromatase inhibitor, and among postmenopausal women without breast
cancer, to:
• AIM 1: Estimate arthralgia time-to-onset, prevalence, incidence, background
rate, trajectories, and risk factors
• AIM 2: Measure the impact of arthralgia on health-related quality of life and
medication adherence (adherence for AI pts only)
• SECONDARY AIM: Develop a roster of current physician-advised or prescribed
treatments, as well as self-management techniques being used for AI-induced
arthralgia (AI pts only), to further inform intervention development.
