Aromatase Inhibitor Clinical Trial
Official title:
Auricular Point Acupressure to Self-Manage Chronic Pain or Aromatase Inhibitor Musculoskeletal Symptoms in Breast Cancer Survivors: Effectiveness and Scientific Underpinnings
Aromatase inhibitor therapy has become a standard adjuvant endocrine therapy for postmenopausal women with hormone receptor-positive breast cancer. Up to 50% of postmenopausal breast cancer survivors exhibit significant aromatase inhibitor musculoskeletal symptoms, defined as severe joint pain and stiffness. Aromatase inhibitor musculoskeletal symptoms in turn has a negative effect on the women's physical function and quality of life, leading to discontinued aromatase inhibitor therapy and causing significant social and economic burden. Given aromatase inhibitor musculoskeletal symptoms' profound effects, the management of aromatase inhibitor musculoskeletal symptoms is an essential component in cancer care. The investigators propose to test auricular point acupressure- -an innovative, non-invasive, nonpharmacologic, and low-cost intervention- -to manage aromatase inhibitor musculoskeletal symptoms in breast cancer survivors. Auricular point acupressure applies an acupuncture-like stimulation to ear acupoints without using a needle (i.e., seeds are taped to the acupoints) to treat illness/symptoms. Auricular point acupressure is particularly well suited for current challenges of unmet aromatase inhibitor musculoskeletal symptoms management. The investigators propose a randomized controlled trial to (1) determine the efficacy of auricular point acupressure in relieving aromatase inhibitor musculoskeletal symptoms, and (2) examine the inflammatory signaling of auricular point acupressure effects in breast cancer survivors treated with aromatase inhibitor. The investigators will also measure psychological, behavioral, personal, and social factors that may moderate or mediate the effects of auricular point acupressure. The investigators also believe inflammatory cytokines may partially explain the mechanism of action of auricular point acupressure for improved aromatase inhibitor musculoskeletal symptoms and physical function, and plan to measure these. This study will identify a novel approach to manage aromatase inhibitor musculoskeletal symptoms in postmenopausal breast cancer survivors, with minimal side effects. If successful, the paradigm of pain management will shift from a traditional medical model to a larger integrative medicine and patient-management paradigm to avoid unnecessary evolution towards prolonged disability.
