Abstract
PURPOSE: Aromatase inhibitor (AI)-induced arthralgia (AIA) is a common side effect that may lead to premature discontinuation of effective hormonal therapy in patients with breast cancer. Acupuncture may relieve joint pain in patients with AIA. We conducted a meta-analysis of randomized controlled trials (RCTs) to evaluate the effectiveness of acupuncture in pain relief in AIA. METHODS: The PubMed, Embase, Cochrane Library, and Scopus databases and the ClinicalTrials.gov registry were searched for studies published before February 2017. Individual effect sizes were standardized, and a meta-analysis was conducted to calculate the pooled effect size by using a random effect model. Pain was assessed using the Brief Pain Inventory (BPI) and Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) at 3-4, 6-8, and 12 weeks. Secondary outcomes included disability level, upper extremity function, physical performance, and quality of life. RESULTS: Five trials involving 181 patients were reviewed. Significant pain reduction was observed after 6-8 weeks of acupuncture treatment. Patients receiving acupuncture showed a significant decrease in the BPI worst pain score (weighted mean difference [WMD]: -3.81, 95% confidence interval [CI]: -5.15 to -2.47) and the WOMAC pain score (WMD: -130.77, 95% CI: -230.31 to -31.22) after 6-8 weeks of treatment. One of the 4 trials reported 18 minor adverse events in 8 patients during 398 intervention episodes. CONCLUSION: Acupuncture is a safe and viable nonpharmacologic treatment that may relieve joint pain in patients with AIA. Additional studies involving a higher number of RCTs are warranted.
