Acupuncture in Reducing Muscle and Bone Symptoms in Women Receiving Letrozole, Exemestane, or Anastrozole for Stage 0, Stage I, Stage II, or Stage III Breast Cancer

Overview

RATIONALE: Acupuncture may help relieve muscle and bone pain caused by aromatase inhibitor therapy, such as letrozole, exemestane, and anastrozole. PURPOSE: This randomized phase II trial is studying acupuncture to see how well it works in reducing muscle and bone symptoms in women receiving letrozole, exemestane, or anastrozole for stage 0, stage I, stage II, or stage III breast cancer.

OBJECTIVES: Primary * To determine if acupuncture can reduce aromatase inhibitor (AI)-associated musculoskeletal symptom severity, in terms of function and pain, in woman with stage 0-III breast cancer. Secondary * To assess if acupuncture decreases oral analgesic use in these patients. * To assess if acupuncture decreases the proportion of patients who change or discontinue AI therapy. * To assess if acupuncture improves menopausal symptoms, mood (i.e., depression or anxiety), sleep quality and sleep disturbance, and overall quality of life of these patients. * To assess if acupuncture changes plasma concentrations of estrogens (i.e., E1, E2, and E1S), cytokine profile, and beta endorphin. OUTLINE: This is a multicenter study. Patients are stratified according to participation in the aromatase inhibitor trial, "A Multicenter Randomized Clinical Trial Correlating the Effects of 24 Months of Exemestane or Letrozole on Surrogate Markers of Response With Aromatase Polymorphism" (yes vs no). Patients are randomized to 1 of 2 treatment arms. * Arm I (control): Patients receive 8 weekly sessions of sham acupuncture treatment comprising 20 minutes of a non-penetrating device consisting of a retractable needle and an adhesive tube on the skin using the Park Sham Device (PSD) in 14 non-acupuncture points. Patients may receive 4 free acupuncture sessions (not sham) after the 12-week (previously 24-week) follow-up visit. * Arm II (treatment): Patients receive 8 weekly sessions of acupuncture treatment comprising 20 minutes of needle insertion in 15 acupuncture points including CV 4, CV 6, CV12 and bilateral LI 4, MH 6, GB 34, ST 36, KI 3, BL 65. Quality of life is assessed periodically to measure changes in symptoms that may be related to hot flashes and estrogen deprivation (i.e., menopausal symptoms, mood \[depression and anxiety\], sleep quality, and overall quality of life using the menopausal symptoms checklist); the Hot Flash Related Daily Interference Scale (HFRDI) and the Hot Flash Daily Diary; the Pittsburgh Sleep Quality Index (PSQI); the Center for Epidemiologic Studies Depression Scale (CESD); the Hospital Anxiety and Depression Scale (HADS-A); and the EuroQOL. Patients complete questionnaires including the Health Assessment Questionnaire (HAQ) and visual analog scales (VAS) to assess both pain and global health status at baseline, after 4 and 8 weeks of acupuncture or sham acupuncture, and at follow-up at 12 weeks (previously 24 weeks). The average amount of daily oral analgesic usage is assessed at weeks 0, 4, 8, and 12(previously 24). Patients undergo blood sample collection periodically for correlative studies. Samples are analyzed for plasma concentrations of estrogen (i.e., estrone E1, estradiol E2, and estrone sulfate E1S) via HPLC-MS/MS, level of 35 serum cytokines via addressable laser bead immunoassay (ALBIA) or classical sandwich ELISA, cytokines and their soluble receptors via classical sandwich ELISA techniques, and Beta-endorphin via competitive ELISA. All patients are followed for 12 weeks(previously 24 weeks). Patients in arm I may be followed for an additional 4 weeks if they choose to receive the free acupuncture sessions.
