BackgroundBreast cancer is the most prevalent cancer in women worldwide. Treatment for breast cancer can be expensive, painful and can significantly affect the quality of life, leading to various side effects such as depression and anxiety, fatigue, sleep disorders, and cognitive impairment. Tai Chi Chuan (TCC) is the most prominent manifestation of tai chi in Chinese martial arts. TCC has been reported to be potentially effective for health and well-being of both the sick and the healthy. However, it is still controversial whether TCC benefits breast cancer patients. It is therefore of great value to evaluate the effectiveness of TCC on the psychological well-being and quality of life in people with breast cancer.MethodsThis review will summarize and meta-analyze all relevant randomized controlled trials on TCC in patients with breast cancer in the light of their anxiety, depression and fatigue level, inflammatory cytokine as well as quality of life, sleep quality, and cognitive function. The following electronic databases will be searched: PubMed, Cochrane Library, EMBASE, Web of Science, China National Knowledge Infrastructure Database, Chinese Biomedical Literature Database, VIP Chinese Science and Technology Periodical Database, and Wan Fang Data. The methodologic quality of randomized controlled trials has been assessed using the Cochrane risk assessment tool. All trials included are analyzed according to the criteria of the Cochrane Handbook. Review Manager 5.3, R-3.5.1 software and grading of recommendations assessment, development, and evaluation pro-GDT online software are used for data synthesis and analysis.ResultsThe results of this systematic review will be used to summarize and evaluate the evidence available from randomized controlled clinical trials of TCC as supportive and adjuvant therapy for breast cancer.ConclusionThis review will provide a detailed summary of the evidence to assess the effectiveness of TCC for breast cancer.Osf RegistrationDOI 10.17605/OSF.IO/Z2FSA.
