Observational Study to Evaluate Mechanisms of Aromatase Inhibitor Associated Musculoskeletal Symptoms

March 3, 2016 updated by: Lynn Henry

Prospective Observational Study of Breast Cancer Patients Starting Therapy With an AI to Evaluate Mechanisms Underlying Development of Aromatase Inhibitor Associated Musculoskeletal Symptoms

Early stage hormone receptor positive breast cancer is typically treated with adjuvant endocrine therapy in order to decrease risk of breast cancer recurrence and to improve overall survival from the disease. Typical agents used for treatment include tamoxifen and the aromatase inhibitors. In postmenopausal women, aromatase inhibitor therapy is increasingly common because it is associated with fewer long-term serious toxicities compared to tamoxifen. However, aromatase inhibitors cause arthralgias in 40-50% of patients, which can influence adherence to therapy and can lead to treatment discontinuation in a minority of cases. The mechanism underlying development of this toxicity remains unclear, and predictors of who will develop these symptoms remain undefined. This observational study is designed to collect patient-reported outcomes and serial serum samples in order to investigate potential etiologies of this bothersome toxicity.
