Prevention of chemotherapy-induced nausea and vomiting with acupuncture

BACKGROUND: Nausea and vomiting are the most common complications following chemotherapy and usually lead to decreased quality of life. Acupuncture therapy is an effective method for chemotherapy-induced nausea and vomiting (CINV), the effects and safety have been observed by many clinicians and demonstrated in a systematic review, which was included in the Cochrane Library in 2014. After several years, new studies have occurred and an updated systematic evaluation is needed. This protocol describes a method for performing a systematic review and meta-analysis to further evaluate the beneficial effects and safety of acupuncture for CINV. METHODS: A searching strategy will be carried out mainly in eight databases in English and Chinese, Cochrane Central Register of Controlled Trials, PubMed, Embase, China National Knowledge Infrastructure, the Chinese Scientific Journal Database, the Wanfang database, China Doctoral Dissertations Full-text Database, and China Master's Theses Full-text Database. Only randomized controlled trials related to acupuncture for CINV will be included to enhance the effectiveness. The effective percentage will be used as primary outcome. Changes in the symptoms of nausea and vomiting, like severity, duration, and frequency as well as quality of life will be assessed as secondary outcome. Side effects and adverse events will be used as safety evaluations. To ensure the quality of the systematic evaluation, study selection, data extraction, and quality assessment will be independently performed by 2 authors, and the third author will deal with any disagreement. The Review Manager V.5.3.3 s will be used to perform the data synthesis and subgroup analysis. RESULTS: There are additional studies, further explanations and more subgroup analyses compared with the previous systematic analysis to determine the effects and safety of acupuncture for CINV. CONCLUSION: The result of this systematic review may offer clinicians stronger evidence to assist patient in relieving CINV. ETHICS AND DISSEMINATION: There is no need to acquire ethical approval for individuals come from literatures instead of recruiting directly. The findings of this review will be reported in peer-reviewed publications and/or presented at relevant conferences TRIAL REGISTRATION NUMBER:: CRD42016045223.
