Tai Chi and Qigong for cancer-related symptoms and quality of life: a systematic review and meta-analysis
Open accessAbstract
Purpose This study aims to summarize and critically evaluate the effects of Tai Chi and Qigong (TCQ) mind-body exercises on symptoms and quality of life (QOL) in cancer survivors.Methods A systematic search in four electronic databases targeted randomized and non-randomized clinical studies evaluating TCQ for fatigue, sleep difficulty, depression, pain, and QOL in cancer patients, published through August 2016. Meta-analysis was used to estimate effect sizes (ES, Hedges' g) and publication bias for randomized controlled trials (RCTs). Methodological bias in RCTs was assessed.Results Our search identified 22 studies, including 15 RCTs that evaluated 1283 participants in total, 75% women. RCTs evaluated breast (n = 7), prostate (n = 2), lymphoma (n = 1), lung (n = 1), or combined (n = 4) cancers. RCT comparison groups included active intervention (n = 7), usual care (n = 5), or both (n = 3). Duration of TCQ training ranged from 3 to 12 weeks. Methodological bias was low in 12 studies and high in 3 studies. TCQ was associated with significant improvement in fatigue (ES = - 0.53, p < 0.001), sleep difficulty (ES = - 0.49, p = 0.018), depression (ES = - 0.27, p = 0.001), and overall QOL (ES = 0.33, p = 0.004); a statistically non-significant trend was observed for pain (ES = - 0.38, p = 0.136). Random effects models were used for meta-analysis based on Q test and I 2 criteria. Funnel plots suggest some degree of publication bias. Findings in non-randomized studies largely paralleled meta-analysis results.Conclusions Larger and methodologically sound trials with longer follow-up periods and appropriate comparison groups are needed before definitive conclusions can be drawn, and cancer- and symptom-specific recommendations can be made.Implications for cancer survivors TCQ shows promise in addressing cancer-related symptoms and QOL in cancer survivors.

A 2018 meta-analysis of 22 studies (15 RCTs and 7 nonrandomized controlled trials; n = 1,283) associated TCQ with significant improvement in fatigue (g = -0.53), depression (g = -0.27), and QL (g = 0.33).
“In another 2018 meta-analysis of 22 studies (15 RCTs and 7 nonrandomized controlled trials; n = 1,283), TCQ was associated with significant improvement in fatigue (g = -0.53),depression (g = -0.27),and QL (g = 0.33) (Wayne et al. 2018).”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
