Abstract
Although acupuncture has been used in clinical practice for thousands of years, it remains a controversial treatment option to help alleviate pain in cancer patients. In this study, we analyzed published material on randomized trials of acupuncture from MEDLINE published up until July 31, 2018, to assess its effects on pain experienced by cancer patients. Revman 5.0 software was used to conduct meta-analysis with pain score as the index. The results of nine randomized controlled trials involving 592 patients were analyzed and showed that acupuncture can relieve the pain caused by aromatase inhibitors. Weighted mean difference of worst pain and pain severity was -3.03, 95% CI (-3.90,-2.16) and -2.69, 95% CI (-4.08,-1.30), respectively (P < 0.01). This led us to conclude that acupuncture has pain relieving effects against pain caused by aromatase inhibitors.
