Acupuncture for Aromatase Inhibitor Induced Joint Pain

Not Applicable

Completed

• Conditions: Breast Cancer
• Interventions: Procedure: Sham Acupuncture; Procedure: Acupuncture

• Registration Number: NCT00826397
• Lead Sponsor: Columbia University

Brief Summary

This is a randomized, controlled, pilot study to determine the safety and efficacy of acupuncture as an adjunct to pharmacological treatment compared to pharmacological intervention alone for the treatment of musculoskeletal pain related to aromatase inhibitors (AI) in postmenopausal breast cancer patients. Twenty participants (20 in each arm) will be enrolled at the Breast Oncology clinic at Columbia University Medical Center (CUMC). Patients in the treatment arm will receive acupuncture administered twice weekly for six weeks and will be allowed to take pain medication as necessary. The control patients will initially receive pain medication alone, then will cross-over to the acupuncture arm after six weeks. The investigators hypothesize that acupuncture will reduce AI induced joint symptoms.

The study will enroll a total of 40 patients, half of whom will be randomized to one of the two arms to receive acupuncture plus pharmacological treatment (arm A) or pharmacological treatment alone (arm B). Joint pain will be assessed by the BPI-SF score at baseline and six weeks. All patients will have a baseline BPI worst pain item (#2) ≥3 points on a scale of 0-10.

Detailed Description

The purpose of this study is to determine the safety and efficacy of acupuncture as a complementary therapy to pain medication for joint pain associated with aromatase inhibitors for breast cancer treatment. Breast cancer patients are living longer largely due to the benefits of hormonal therapy. Aromatase inhibitors (AIs) are a new class of hormonal agents which block estrogen synthesis in postmenopausal women. However, musculoskeletal pain occurs in up to 50% of patients treated with AIs and often does not respond to conventional pain medications. AI-induced joint pain interferes with patient compliance and may cause major disability. Therefore, safe and effective treatments are needed to alleviate AI-induced musculoskeletal pain.

Acupuncture is a traditional Chinese method of medical treatment and a popular modality for treating musculoskeletal pain. Acupuncture involves the use of thin needles to stimulate specific points of the body and leads to pain control through the release of endorphin in the central nervous system. Clinical trials have found a benefit of acupuncture for the treatment of knee and back pain. Given the lack of effective treatments for AI-induced joint pain and the safety and efficacy of acupuncture, it is therefore reasonable to evaluate whether acupuncture is effective in breast cancer patients who experience musculoskeletal pain related to AIs.

Arm && Interventions

Group	Intervention	Description
Control Arm	Sham Acupuncture	The control patients will receive a form of sham acupuncture, which will consist of superficial needling at nonspecific body points, administered twice weekly for six weeks.
Acupuncture Arm	Acupuncture	Patients in the treatment arm will receive acupuncture administered twice weekly for six weeks and will be allowed to take pain medication as necessary.

Primary Outcome Measures

Name	Time	Method
Change in Joint Pain	Baseline and 6 weeks	This is defined as the difference in the Brief Pain Inventory - Short Form (BPI-SF) scale at six weeks versus baseline.

Secondary Outcome Measures

Name	Time	Method
Change in Joint Stiffness and Function	Baseline and 6 weeks	The Western Ontario and McMaster Universities Osteoarthritis (WOMAC) index Version 3.1 will be used and consists of 24 questions related to three subscales: pain (0-20), stiffness (0-8) and physical function (0-68).
Safety and Tolerability measured by Frequency of Adverse Events	6 weeks	Reporting of the severity and frequency of adverse events (NCI Common Terminology Criteria Version 3.0) (40) related to the interventions will be conducted every two weeks during telephone interviews. All treatment-related adverse events will be reported for both treatment arms.
