Tai Chi for cancer survivors: A systematic review toward consensus-based guidelines

The effect of traditional Chinese medicine on psychological conditions among elderly patients with cancer: a scoping review

Coping with cancer presents a multitude of challenges that encompass every aspect of a patient's life. These challenges not only strain the body but also weigh heavily on the mind, often culminating in profound psychological distress for cancer patients. The cumulative burden of these experiences can heighten the risk of developing psychiatric disorders, exacerbating the already daunting landscape of cancer care. Therefore, this study reviewed the available research with the aim of investigating the effects of traditional Chinese medicine on psychological conditions in elderly cancer patients. In this scoping review, we applied specific criteria to select studies that focused on elderly patients with cancer. We performed an extensive search across electronic databases, including Embase, Science Direct, PubMed, Google Scholar, Scopus, Cochrane Library and Web of Science. In our investigation, we identified a total of 3870 articles related to the topic under review. Following a meticulous screening process that involved evaluating titles, abstracts, and full texts, we ultimately selected five articles deemed relevant for inclusion in this review. Among these articles, three were randomised studies, while the remaining two were review articles. The outcomes of our analysis revealed that herbal decoctions, nutritional counselling, Tai Chi and acupressure, can effectively improve various psychological outcomes in elderly cancer patients. These interventions reduce fatigue, depression, anxiety, and stress, while also enhancing sleep quality and overall mental health. The present study highlights the importance of traditional Chinese medicine in addressing the needs of elderly patients with cancer. As a result, it is recommended that further extensive research be conducted to comprehensively assess the efficacy and safety of traditional Chinese medicine in managing cancer in the elderly.

Can strength training or tai ji quan training reduce frailty in postmenopausal women treated with chemotherapy? A secondary data analysis of the GET FIT trial

PURPOSE

To determine whether strength training or tai ji quan can reduce frailty in older, postmenopausal women treated with chemotherapy for cancer.

METHODS

We conducted a secondary data analysis from a 3-arm, single-blind, randomized controlled trial where older (50-75 years), postmenopausal women cancer survivors were randomized to supervised group exercise programs: tai ji quan, strength training, or stretching control for 6 months. We assessed frailty using a 4-criteria model consisting of weakness, fatigue, inactivity, and slowness. Using logistic regression, we determined whether the frailty phenotype (pre-frailty or frailty) decreased post-intervention, how many and which frailty criteria decreased, and what characteristics identified women most likely to reduce frailty.

RESULTS

Data from 386 women who completed baseline and 6-month testing were used (mean age of 62.0 ± 6.4 years). The odds of reducing overall frailty over 6 months were significantly higher in the strength training group compared to controls (OR [95%CI] 1.86 [1.09, 3.17]) but not for tai ji quan (1.44 [0.84, 2.50]). Both strength training (OR 1.99 [1.10, 3.65]) and tai ji quan (OR 2.10 [1.16, 3.84]) led to significantly higher odds of reducing ≥ 1 frailty criterion compared to controls. Strength training led to a three-fold reduction in inactivity (p < 0.01) and tai ji quan to a two-fold reduction in fatigue (p = 0.08) versus control. Higher baseline BMI, comorbidity score, and frailty status characterized women were more likely to reduce frailty than other women.

CONCLUSIONS

Strength training appears superior to tai ji quan and stretching with respect to reducing overall frailty phenotype among postmenopausal women treated with chemotherapy for cancer, but tai ji quan favorably reduced the number of frailty criteria.

TRIAL REGISTRATION

ClinicalTrials.gov identifier: GET FIT was registered as a clinical trial in clinicaltrials.gov: NCT01635413.

IMPLICATIONS FOR CANCER SURVIVORS

Supervised, group exercise training that emphasizes strength training and/or tai ji quan may help combat accelerated aging and reduce frailty after cancer treatment.

The effect of Tai Chi/Qigong on depression and anxiety symptoms in adults with Cancer: A systematic review and meta-regression

OBJECTIVE

We expand on prior systematic reviews of Tai chi/Qigong (TCQ) practice on depression or anxiety symptoms in adults with cancer to estimate the mean effect of TCQ on depression and anxiety in randomized controlled trials. Additionally, we perform moderator analysis to examine whether effects vary based on patient features, TCQ stimuli properties, or characteristics of research design.

METHODS

Guided by PRISMA guidelines, we located articles published before August 31, 2023 using a combination of electronic database search and a complementary manual search through reference lists of articles and published reviews. Two separate multilevel meta-analyses with random-effects model were employed to estimate the overall effect of TCQ on depression and anxiety respectively. Further, multilevel meta-regression analysis was utilized to examine moderating effects based on moderators derived from patient features, TCQ stimuli properties, or characteristics associated with research design. Meta-analyses were performed in R4.0.0 and certainty of evidence with GRADEpro software.

RESULTS

The TCQ intervention yielded a standardized mean effect size of 0.29 (95% CI, 0.18 to 0.40) for anxiety, indicating homogeneity among the included studies. Conversely, for depression, the standardized mean effect size was 0.35 (95% CI, 0.14 to 0.55), signifying heterogeneity: reductions were larger when the trial primary outcome, predominantly function-related outcomes, changed significantly between the TCQ and control group.

CONCLUSIONS

TCQ practice exhibits small-to-moderate efficacy in alleviating depression and anxiety symptoms among cancer patients and survivors. Moreover, patients with depressive symptoms for whom TCQ intervention coupled with improvements in function-related outcomes manifested greater antidepressant effect.

Perspectives and experiences of leisure-time physical activity in adults with stage 4 cancer: a qualitative interpretive-description study

PURPOSE

Leisure-time physical activity (LTPA) can be beneficial for individuals with advanced cancer, but little is known on how to tailor rehabilitation strategies targeting LTPA in cancer care. Our objective was to explore perspectives and experiences of LTPA in people with stage 4 cancer.

MATERIALS AND METHODS

Guided by interpretive-description methodology, our qualitative study consisted of individual, semi-structured interviews with 20 Canadian adults diagnosed with stage 4 cancer. Interviews were transcribed verbatim and analyzed inductively.

RESULTS

The participants' median age was 51.5 (range, 35-73) years. Cancer types included breast (n = 12), lung (n = 4), and other (n = 4). Participants highlighted their experiences of LTPA as diverse and complex, impacted by individual and cancer-related factors. They emphasized being intentional with LTPA through activity planning and modification. LTPA participation was linked to physical well-being, social connections, and meanings of accomplishment and loss. Many participants desired personalized support related to LTPA, that is integrated, interprofessional, and accessible in cancer care.

CONCLUSION

The experiences of LTPA for people with stage 4 cancer are personal and connected to health and psychosocial meanings. Further efforts in rehabilitation are needed to address the challenges faced by people with advanced cancer and optimize safe, meaningful participation in LTPA.IMPLICATIONS FOR REHABILITATIONExperiences of leisure-time physical activity in individuals with stage 4 cancer are personal and linked to health benefits and psychosocial meanings.Activity participation frequently involves consideration of cancer-related symptoms, management of risks, and intentional planning and modification of activities.Trained rehabilitation professionals integrated in cancer care may be well suited to support people with stage 4 cancer through personalized activity recommendations.This research can help inform future clinical, research, and educational efforts in rehabilitation aimed at targeting physical activity in individuals with advanced cancer.

Effects of different Chinese traditional exercises on sleep quality and mental health of adults: systematic review and meta-analysis

OBJECTIVE

To evaluate the effects of traditional Chinese exercises on sleep quality and mental health in adults with different health statuses. METHOD   : This review was registered a priori (CRD42023382188) and executed according to PRISMA statement guidelines. We searched the databases CNKI, China Biology Medicine disc (CBM), Wangfang, PubMed, Web of Science, and Embase from the date of database creation to March 2023. Two researchers independently screened the literature, extracted the data, evaluated the methodological quality of the included literature, and then used Revman 5.4 and Stata 17.0 for the corresponding statistical analysis and graphing.

RESULTS

Thirty-four randomized controlled trials (RCTs) were included, with a total sample of 2563 adults (1276 in the experimental group and 1287 in the control group). The meta-analysis results showed that traditional Chinese exercise significantly improved sleep quality in different groups [WMD =  - 1.58, 95% CI =  - 2.17, - 1.00, P < 0.00001] and that Badaanjin was better than Taijiquan in improving sleep quality. For mental health, traditional Chinese exercise had good effects on anxiety [WMD =  - 1.66, 95% CI =  - 2.64, - 0.69, P = 0.0009] and depression [WMD =  - 1.67, 95% CI =  - 3.23, - 0.11, P = 0.04].

CONCLUSION

Traditional Chinese exercises can improve the quality of sleep and mental health in different groups of people and are highly recommended for good health effects.

Exploring Guolin Qigong (Mind-Body Exercise) for Improving Cancer Related Fatigue in Cancer Survivors: A Mixed Method Randomized Controlled Trial Protocol

BACKGROUND

Cancer-related fatigue and its associated symptoms of sleep disorder and depression are prevalent in cancer survivors especially among breast, lung, and colorectal cancer survivors. While there is no gold standard for treating cancer-related fatigue currently, studies of mind-body exercises such as Qigong have reported promise in reducing symptoms. This study was designed to evaluate the feasibility and effect of Guolin Qigong on cancer-related fatigue and other symptoms in breast, lung and colorectal cancer survivors while exploring their perceptions and experiences of Guolin Qigong intervention.

METHODS

This is an open-label randomized controlled trial with 60 participants divided into 2 study groups in a 1:1 ratio. The intervention group will receive 12 weeks of Guolin Qigong intervention with a 4-week follow-up while control will receive usual care under waitlist. The primary outcome will be feasibility measured based on recruitment and retention rates, class attendance, home practice adherence, nature, and quantum of missing data as well as safety. The secondary subjective outcomes of fatigue, sleep quality and depression will be measured at Week-1 (baseline), Week-6 (mid-intervention), Week-12 (post-intervention), and Week-16 (4 weeks post-intervention) while an objective 24-hour urine cortisol will be measured at Week-1 (baseline) and Week-12 (post-intervention). We will conduct a semi-structured interview individually with participants within 3 months after Week-16 (4 weeks post-intervention) to obtain a more comprehensive view of practice adherence.

DISCUSSION

This is the first mixed-method study to investigate the feasibility and effect of Guolin Qigong on breast, lung, and colorectal cancer survivors to provide a comprehensive understanding of Guolin Qigong's intervention impact and participants' perspectives. The interdisciplinary collaboration between Western Medicine and Chinese Medicine expertise of this study ensures robust study design, enhanced participant care, rigorous data analysis, and meaningful interpretation of results. This innovative research contributes to the field of oncology and may guide future evidence-based mind-body interventions to improve cancer survivorship.

TRIAL REGISTRATION

This study has been registered with ANZCTR (ACTRN12622000688785p), was approved by Medical Research Ethic Committee of University Malaya Medical Centre (MREC ID NO: 2022323-11092) and recognized by Western Sydney University Human Research Ethics Committee (RH15124).

Review of psychological interventions in patients with cancer

OBJECTIVE

Cancer is one of the leading causes of mortality in the world and also causes morbidity and deterioration in the mental health of patients and their caregivers. The most commonly reported psychological symptoms include anxiety, depression, and the fear of recurrence. The purpose of this narrative review is to elaborate and discuss the effectiveness of the different interventions employed and their utilities in clinical practice.

METHODS

Scopus and PubMed databases were searched, with a timeframe from 2020 to 2022, to identify randomised controlled trials, meta-analyses, and reviews and reported using PRISMA guidelines. Articles were searched by the following keywords: "cancer, psychology, anxiety, and depression". An additional search was performed with the keywords "cancer, psychology, anxiety, depression, and [intervention name]". The most popular psychological interventions were included in these search criteria.

RESULTS

A total of 4829 articles were retrieved by the first preliminary search. After reducing duplicates, 2964 articles were assessed for inclusion according to eligibility criteria. After the full-text screening, 25 final articles were chosen. To systematise psychological interventions as described in the literature, the authors have divided them into 3 broad categories, each type targeting a specific domain of mental health: cognitive-behavioural, mindfulness, and relaxation.

CONCLUSION

The most efficient psychological therapies, as well as therapies which require more extensive research, were outlined in this review. The authors discuss the necessity of primary assessment of patients and whether they require the help of a specialist. With the limitations of the potential risk of bias, an overview of different therapies and interventions targeting various psychological symptoms is outlined.

Is physical activity effective against cancer-related fatigue in lung cancer patients? An umbrella review of systematic reviews and meta-analyses

OBJECTIVES

To discuss the effects of physical activity on cancer-related fatigue (CRF) in lung cancer patients, summarize the types of physical activity in the published reviews, assess the quality of the evidence, and provide suggestions for the clinical selection of exercise intervention.

METHODS

PubMed, EMBASE, Web of Science, and the Cochrane Database of Systematic Reviews were searched through 8 November 2021 to identify relevant systematic reviews and meta-analyses. We also performed a manual search of the reference lists of included articles as supplements. Two researchers independently performed literature screening, data extraction, and quality assessment. The umbrella review has been registered in the International Prospective Register of Systematic Review (PROSPERO) registry (CRD42021292548).

RESULTS

From the 13 systematic reviews or meta-analyses identified, 10 physical activity interventions were included. The most mentioned intervention was aerobic combined with resistance exercise; however, no reduction of the symptoms of CRF was observed in lung cancer patients by this exercise intervention. Most of the patients who performed aerobic exercises alone showed improvement in CRF after the intervention. In addition, Tai Chi and breathing exercises have been shown to improve fatigue, but more high-quality research is still needed to support its effectiveness.

CONCLUSIONS

Aerobic exercise, respiratory muscle training, aerobic combined with balance training, and other exercise interventions have been shown to improve CRF in lung cancer patients. But it should be noted that according to the different treatment methods and disease stages of patients, individualized rehabilitation programs should be developed for patients. Due to the low methodological quality and evidence quality of some systematic reviews and meta-analyses included in this study, more high-quality clinical studies and systematic reviews are still needed for validation in the future. This umbrella review helps to identify effective ways of exercise to improve fatigue in lung cancer patients before dedicated evidence-based medical guidelines are established.

Review of Under-Recognized Adjunctive Therapies for Cancer

Patients and providers may not be aware that several adjunctive measures can significantly improve the quality of life, response to treatment, and possibly outcomes for cancer patients. This manuscript presents a review of practical under-recognized adjunctive therapies that are effective including exercise; stress-reduction techniques such as mindfulness, massage, yoga, Tai Chi, breathing exercises; importance of sleep quality; diet modifications such as calorie restriction at the time of chemotherapy and avoidance of high carbohydrate foods; supplements such as aspirin, green tea, turmeric, and melatonin; and repurposed prescription medications such as metformin and statins. Each recommendation should be tailored to the individual patient to assure no contraindications.

Association of Daily Sitting Time and Leisure-Time Physical Activity With Survival Among US Cancer Survivors

IMPORTANCE

Sedentary behaviors, particularly prolonged sitting and lack of physical activity, may influence survival after cancer.

OBJECTIVE

To examine the independent and joint associations of daily sitting time and leisure-time physical activity with mortality outcomes among cancer survivors.

DESIGN, SETTING, AND PARTICIPANTS

A prospective cohort of a nationally representative sample of cancer survivors, age 40 years or older (n = 1535; weighted population, 14 002 666), from the US National Health and Nutrition Examination Survey from 2007 to 2014. Participants were linked to mortality data from their interview and physical examination date through December 31, 2015. Daily sitting time and leisure-time physical activity (LTPA) were self-reported using the Global Physical Activity Questionnaire. Data analyses were performed from January 1 to May 1, 2021.

MAIN OUTCOMES AND MEASURES

All-cause, cancer-specific, and noncancer mortality.

RESULTS

Among 1535 cancer survivors (mean [SE] age, 65.1 [0.4] years; 828 [60.1%] females; 945 [83.1%] non-Hispanic White individuals), 950 (56.8%) reported LTPA of 0 minutes per week (min/wk) during the previous week (inactive); 226 (15.6%) reported LTPA of less than 150 min/wk (insufficiently active); 359 (27.6%) reported LTPA of 150 min/wk or more (active); 553 (35.4%) reported sitting for 6 to 8 hours per day (h/d); and 328 (24.9%) reported sitting for more than 8 h/d. Of note, 574 (35.8%) cancer survivors reported no LTPA with concurrent sitting of more than 6 h/d. During the follow-up period of up to 9 years (median, 4.5 years; 6980 person-years), there were 293 deaths (cancer, 114; heart diseases, 41; other causes, 138). Multivariable models showed that being physically active was associated with lower risks of all-cause (hazard ratio [HR], 0.34; 95% CI, 0.20-0.60) and cancer-specific (HR, 0.32; 95% CI, 0.15-0.70) mortality compared with inactivity. Sitting more than 8 h/d was associated with higher risks of all-cause (HR, 1.81; 95% CI, 1.05-3.14) and cancer-specific (HR, 2.27; 95% CI, 1.08-4.79) mortality compared with those sitting less than 4 h/d. In the joint analyses, prolonged sitting was associated with an increased risk of death among cancer survivors who were not sufficiently active. Specifically, inactive and insufficiently active survivors reported sitting more than 8 h/d had the highest overall (HR, 5.38; 95% CI, 2.99-9.67) and cancer-specific (HR, 4.71; 95% CI, 1.60-13.9) mortality risks.

CONCLUSIONS AND RELEVANCE

In this cohort study of a nationally representative sample of US cancer survivors, the combination of prolonged sitting with lack of physical activity was highly prevalent and was associated with the highest risks of death from all causes and cancer.

Tai Chi for cancer survivors: A systematic review toward consensus-based guidelines

To manage acute, long‐term, and late effects of cancer, current guidelines recommend moderate‐to‐vigorous intensity aerobic and resistance exercise. Unfortunately, not all cancer survivors are able or willing to perform higher intensity exercise during difficult cancer treatments or because of other existing health conditions. Tai Chi is an equipment‐free, multicomponent mind–body exercise performed at light‐to‐moderate intensity that may provide a more feasible alternative to traditional exercise programs for some cancer survivors. This systematic review evaluated the therapeutic efficacy of Tai Chi across the cancer care continuum. We searched MEDLINE/PubMed, Embase, SCOPUS, and CINAHL databases for interventional studies from inception to 18 September 2020. Controlled trials of the effects of Tai Chi training on patient‐reported and objectively measured outcomes in cancer survivors were included. Study quality was determined by the RoB 2 tool, and effect estimates were evaluated using the Best Evidence Synthesis approach. Twenty‐six reports from 14 trials (one non‐randomized controlled trial) conducted during (n = 5) and after treatment (after surgery: n = 2; after other treatments: n = 7) were included. Low‐level evidence emerged to support the benefits of 40–60 min of thrice‐weekly supervised Tai Chi for 8–12 weeks to improve fatigue and sleep quality in cancer survivors. These findings need to be confirmed in larger trials and tested for scaling‐up potential. Insufficient evidence was available to evaluate the effects of Tai Chi on other cancer‐related outcomes. Future research should examine whether Tai Chi training can improve a broader range of cancer outcomes including during the pre‐treatment and end of life phases.
