Auricular Point Acupressure to Manage Chemotherapy Induced Neuropathy

Chemotherapy-induced neuropathy (CIN)-pain, numbness, or tingling distributed in the hands and feet-produces persistent symptoms affecting sensation and balance in cancer survivors. Up to 50% of cancer survivors still suffer CIN 6 years after treatment. Duloxetine, the only recommended drug by the American Society of Clinical Oncology, was found to be superior to placebo but improved CIN by only 0.73 points (0-10 scale). No effective treatment for CIN has been established except exercise, with an effect size of \<0.508. Opioids relieve CIN pain, but long-term use is strongly discouraged due to opioid overuse. The investigators propose to test auricular point acupressure (APA), an innovative and scalable solution developed from auricular acupuncture. APA is a non-invasive (needleless) and active treatment for patients with pain, whereas acupuncture is an invasive (using needles) and passive treatment (administered by a licensed practitioner). In APA, small seeds are taped on specific ear points by a skilled provider and patients press on the seeds to stimulate ear points three times daily, three minutes per time, for a total of nine minutes per day. APA provides pain relief within 1-2 minutes after ear stimulation and sustains pain relief for one month after a 4-week APA intervention. APA is popular in Taiwan, China, and Europe. Though its use is sparse in the U.S., a limited number of clinical trials have supported APA in pain management.
