Electroacupuncture vs. Auricular Acupressure vs. Waitlist Control for Breast Cancer Endocrine Therapy-Related Joint Pain
Sponsor: First Teaching Hospital of Tianjin University of Traditional Chinese Medicine
Summary
The purpose of this pragmatic, multicenter, randomized controlled trial is to evaluate the clinical effectiveness and safety of electroacupuncture and auricular acupressure for improving joint pain related to endocrine therapy in breast cancer patients. A total of 200 participants will be recruited and randomly assigned to one of three groups: the Electroacupuncture Group (n=80), the Auricular Acupressure Group (n=80), or the Waitlist Control Group (n=40), using a central stratified block randomization method. The primary objective is to compare changes in Worst Pain Item score among the three groups from baseline to the end of the treatment period, as measured by the Brief Pain Inventory-Short Form (BPI-SF). Secondary objectives include assessing pain interference, overall health status through the PROMIS scale, and quality of life specifically related to endocrine therapy using the FACT-ES. Additionally, the study will evaluate analgesic medication use (QAQ), patient expectations (Acupuncture Expectancy Scale), treatment adherence, and the occurrence of adverse events. By comparing these interventions, this study aims to generate high-quality evidence for the management of treatment-related arthralgia in breast cancer survivors.

Interventions
Electroacupuncture Group
Electroacupuncture is performed using the basic prescription combined with the prescription for the affected joints. Basic prescription: Shuigou (GV26), Hegu (LI4), Neiguan (PC6), Zusanli (ST36), Yanglingquan (GB34), Taichong (LR3), Sanyinjiao (SP6). On this basis, 1 to 4 additional acupoints are selected based on the two most severely affected joint areas. Needle selection: The acupuncture needles (40 or 75 mm x 0.25 mm gauge, and 40 mm x 0.18 mm gauge, Huatuo, Suzhou, China) will be used. An electroacupuncture stimulator (SDZ-V, Huatuo, Suzhou, China) will be used, delivering alternating frequencies of 2 Hz/10 Hz with no more than four electrode pairs simultaneously.
Auricular Acupressure Group
The auricular acupressure protocol is formed by combining the basic auricular point prescription and the auricular point prescription corresponding to the affected joints. The basic points include Shenmen, Sympathetic, Endocrine, and Subcortex, while the additional points are selected by the acupuncturist based on the 1-2 joint regions with the most pain as reported by the patient. Once identified, Vaccaria seed (Zhongyan Taihe, Beijing, China) is taped onto the points until the patient perceives a distinct sensation of soreness or tenderness. Participants will be instructed to apply pressure to each ear three times per day, pressing each side for approximately 3 minutes per session. The auricular patches will be removed 2 to 4 days after during a follow-up visit at the clinic.
