INTRODUCTION: Aromatase inhibitors (AIs) have become the standard of care for the adjuvant treatment of postmenopausal, hormone-sensitive breast cancer. However, patients receiving AIs may experience joint symptoms, which may lead to early discontinuation of this effective therapy. We hypothesize that acupuncture is a safe and effective treatment for AI-induced arthralgias. METHODS: Postmenopausal women with early-stage breast cancer who had self-reported musculoskeletal pain related to adjuvant AI therapy were randomized in a crossover study to receive acupuncture twice weekly for 6 weeks followed by observation or vice-versa. The intervention included full body and auricular acupuncture, and a joint-specific point prescription. Outcome measures included the Brief Pain Inventory-Short Form (BPI-SF), Western Ontario and McMaster Universities Osteoarthritis (WOMAC) index, the Functional Assessment of Cancer Therapy-General (FACT-G) quality of life measure, and serum levels of inflammatory markers, IL-1 beta and TNF-alpha. RESULTS: Twenty-one women were enrolled and two discontinued early. From baseline to the end of treatment, patients reported improvement in the mean BPI-SF worst pain scores (5.3 to 3.3, p = 0.01), pain severity (3.7 to 2.5, p = 0.02), and pain-related functional interference (3.1 to 1.7, p = 0.02), as well as the WOMAC function subscale and FACT-G physical well-being (p = 0.02 and 0.04, respectively). No adverse events were reported. DISCUSSION/CONCLUSIONS: In this pilot study, acupuncture reduced AI-related joint symptoms and improved functional ability and was well-tolerated. IMPLICATIONS FOR CANCER SURVIVORS: Musculoskeletal side effects are common among breast cancer survivors on adjuvant AI therapy, therefore, effective treatments are needed for symptom relief and to improve adherence to these life-saving medications
