Efficacy and safety of acupuncture in patients with cancer-related fatigue A protocol for systematic review and meta-analysis

Background: Cancer-related fatigue (CRF) is considered a common complication of cancer or cancer treatment, which has a serious adverse effect on the life and of cancer patients, leading to a decline in their quality of life (QoL). The existing clinical trials revealed that acupuncture has a positive effect on CRF, and there are fewer adverse events confirmed in the corresponding systematic review. However, in recent years, new studies on using acupuncture to treat CRF were conducted, so in order to evaluate its efficacy, an updated systematic review. This protocol provides research methods for systematic review and meta-analysis of the safety and effectiveness of acupuncture for the treatment of CRF. Methods: We will searched the randomized controlled trial literature of acupuncture treatment for CRF in 4 English and 4 Chinese databases, including PubMed, MEDLINE, Web of Science, Cochrane Central Register of Controlled Trials (Central), China National Knowledge Infrastructure (CNKI), China Biomedical Literature Database(CBM), China Science Journal Database (VIP), and Wanfang Database. Simultaneously, other resources are manually retrieved which include reference lists of identified publications, conference articles, and grey literature. We also included the clinical randomized controlled trials of acupuncture treatment for CRF in the study. The search language is limited to Chinese and English. Two trained reviewers independently completed research screening, data extraction, and research quality assessment. RevMan (V.5.3) software was used to perform data statistical analysis and Grading of Recommendations Assessment, Development, and Evaluation (GRADE) was used to evaluate the quality of evidence. Results: This study is based on past and present clinical evidence to comprehensively evaluate the effectiveness and safety of acupuncture treatment for CRF. Conclusion: Through this systematic review, we will provide the latest high-quality evidence of whether acupuncture treatment for CRF is effective and safe and also provide a theoretical basis for clinicians to choose acupuncture for the treatment of CRF.
