Effects of Mind-Body Exercise in Cancer Survivors: A Systematic Review and Meta-Analysis.

TLDR: The current evidence demonstrates that mind-body exercise is relatively safe and modestly effective for symptom management in cancer survivors, and randomized trials with larger sample sizes and of higher methodological quality are needed to confirm these results.

Abstract: Objective. Mind-body exercise may have potential benefits for cancer survivors according to previous studies. We performed a systematic review and meta-analysis to summarize the published evidence and evaluate the safety and efficacy of mind-body exercise on general quality of life (QOL) and symptom management in cancer survivors. Methods. Four English language databases were systematically searched for existing randomized controlled trials (RCTs) of mind-body exercise in cancer survivors from database inception through October 23, 2019. Methodological quality was appraised with the Cochrane Risk of Bias tool. A meta-analysis of comparative effects was performed using the Review Manager v.5.3 software. Results. Fifteen studies encompassing 1461 patients were included. Analysis results showed that mind-body exercise could have a statistically significant effect on the outcomes of physical fitness, fatigue, sleep quality, depression, anxiety, and BMI, while effects on general QOL and stress were not statistically significant (all ). No serious adverse events were reported. Conclusions. The current evidence demonstrates that mind-body exercise is relatively safe and modestly effective for symptom management in cancer survivors. Furthermore, randomized trials with larger sample sizes and of higher methodological quality are needed to confirm these results.
