“…QOL, a common gauge of cancer treatment effect, is widely used to measure the health of breast cancer patients (70) QOL is a multidimensional assessment with physical (including function/disability and symptoms/complications concepts), mental (including emotional distress, psychological well-being, perceived cognitive functioning, and spiritual/existential concerns concepts) and social (including socioeconomic challenges, role/relationship changes, perceived support/satisfaction, and social participation concepts) domains (70). Yan's and Tao's systematic reviews found TCC failed to improve QOL in breast cancer survivors (71,72), but this study showed 12 weeks TCC had a positive influence on QOL. Three studies in Yan's systematic review were not included in this review because the intervention therapy of two studies (73,74) was Tai Chi combining aerobics, and another study (75) was a prospective longitudinal study from a larger randomized controlled trial.…”

Background: Tai Chi Chuan(TCC), as a mind-body exercise, may have a positive impact on physical function and psychological well-being in breast cancer patients. The latest systematic review and meta-analysis of TCC for breast cancer was made 4 years ago and some new clinical trials about it were published. We remade a systematic review and meta-analysis to evaluate the effect of TCC in breast cancer patients.Methods: In this systematic review and meta-analysis, we searched MEDLINE (via PubMed), EMBASE (via embase.com), CENTRAL, CNKI, COVIP, Wanfang, Chaoxing, CiNii, J-SSTAGE, DBpia, and ThaiJO with no language restrictions from inception to December 31, 2018 (updated on February 16, 2020), for randomized clinical trials comparing TCC with non-exercised therapy in breast cancer patients. The primary outcome was quality of life in patients with breast cancer and data pooled by a randomeffects model. Subgroup analyses were conducted to estimate the effect of different durations of TCC for breast cancer patients. This study was registered in PROSPERO, number CRD 4201810326.Results: Fifteen articles involving a total of 885 breast cancer participants were included in this review. Compared with non-exercised therapy, TCC had a significant effect on quality of life in breast cancer patients (SMD = 0.37, 95% CI 0.15-0.59, p = 0.001), and subgroup analysis found that TCC showed beneficial effect in 12 weeks and 25 weeks (12 weeks: SMD = 0.40, 95% CI 0.19-0.62, p = 0.0003; 25 weeks: SMD = 0.38, 95% CI 0.15-0.62, p = 0.002). Meta-analyses of secondary outcomes showed that 3 weeks TCC increased shoulder function (SMD = 1.08, 95% CI 0.28-1.87, p = 0.008), 12 weeks TCC improved pain (SMD = 0.30, 95% CI 0.08-0.51, p = 0.007), shoulder function (SMD = 1.34, 95% CI 0.43-2.25, p = 0.004), strength of arm (SMD = 0.44, 95% CI 0.20-0.68, p = 0.0004), and anxiety (MD = −4.90, 95% CI −7.83 to −1.98, p = 0.001) in breast cancer patients compared with the control group.Conclusions: TCC appears to be effective on some physical and psychological symptoms and improves the quality of life in patients with breast cancer. Additional randomized controlled trials with a rigorous methodology and low risk of bias are needed to provide more reliable evidence.

“…This raises an issue as cancer patients are in a vulnerable state of mind after diagnoses and the ethics of selling health supplements to patients are questionable especially when the efficacy of CAM use among breast cancer has been investigated and found to have varying results (Hajime et al, 2013;Yan et al, 2014). Although the results of multivariate analyses did not support this information source (other medical staff) as an independent factor influencing CAM use, this may be due to lack of power of the analyses.…”

Background: Breast cancer is a common cancer affecting women in Malaysia and the use of complementary/ alternative medicine (CAM) has been associated with delays in getting treatment. The aim of the study was to explore the use of CAM and the influencing factors in the Northern region of Peninsular Malaysia. Materials and Methods: This was a cross-sectional descriptive study on a convenience sample of 100 Malaysian breast cancer survivors. Findings: The reported use of CAM among the breast cancer survivors was lower than in other studies but the types of CAM used had a similar pattern with nutrition supplements/vitamins being the most common. The factors that positively influenced the use of complimentary/traditional therapy were income and getting information from television or radio. Survivors with access to internet/blogs appear to have lower odds of using complimentary/traditional therapy compared to the respondents who reported no such access. Conclusions: Information transmitted via television and radio appears to have a positive influence on CAM use by breast cancer patients compared to other information sources and it is important to ensure that such information is accurate and impartial.

“…Relative to yoga, tai chi and qigong have been less frequently studied in cancer but have increasingly received attention after a landmark study published in the New England Journal of Medicine suggested therapeutic benefits in patients with fibromyalgia with a single-blinded RCT design [71]. Yet, findings in the cancer literature are believed to be mixed at this stage as two recent meta-analyses (one involving 5 RCT’s of 407 women with breast cancer [72] and one including 13 RCT’s with 592 patients with mixed cancer types [63]) suggested. Both independent reviews concluded that, although treatment gains are evident, caution is warranted due to methodological constraints and the small sample of included trials.…”

Mind-Body Practices in Cancer Care

Being diagnosed with a life threatening disease such as cancer and undergoing treatment can cause unwanted distress and interferes with quality of life. Uncontrolled stress can have a negative effect on a number of biological systems and processes leading to negative health outcomes. While some distress is normal, it is not benign and must be addressed, as failure to do so may compromise health and QOL outcomes. We present the evidence for the role of stress in cancer biology and mechanisms demonstrating how distress is associated with worse clinical outcomes. The National Comprehensive Cancer Network states that all patients be screened with the single-item Distress Thermometer and to also indicate the source of distress and to get appropriate referral. In addition to the many conventional approaches for managing distress from the fields of psychology and psychiatry, many patients are seeking strategies to manage their distress that are outside conventional medicine such as mind-body techniques. Mind-body techniques such as meditation, yoga, tai chi, and qigong have been found to lower distress and lead to improvements in different aspects of quality of life. It is essential that the standard of care in oncology include distress screening and the delivery of different techniques to help patients manage the psychosocial challenges of diagnosis and treatment of cancer.

Abstract: Background: It is controversial whether Tai Chi (TC) benefits breast cancer survivors (BCS) on quality of life (QoL). We therefore undertook a meta-analysis to assess this question.
