The Effectiveness of Yoga on Cancer-Related Fatigue: A Systematic Review and Meta-Analysis

Yoga intervention for colorectal cancer survivors: a qualitative study exploring participants' expectations and experiences

INTRODUCTION

Colorectal cancer (CRC) survivors often struggle with side effects following treatment such as reduced quality of life, fatigue and psychological distress and need therefore efficient comprehensive interventions. The aim of this qualitative study was to explore CRC survivors' expectations before the yoga intervention as well as their unique experiences beyond those reported with standard questionnaires.

METHODS

Interpretative phenomenological approach was used in this qualitative study. Semi-structured interviews were conducted before and after a 10-week yoga program (90 min once a week, Hatha Yoga) with CRC survivors enrolled in a randomized controlled trial. Thematic analysis was used to uncover themes present in participants' accounts.

RESULTS

Nine patients participated in the interviews, mean interview duration was 27.49 min (SD = 7.71) before and 38.41 min (SD = 15.93) after the intervention. Our analysis identified following themes: (1) representations and expectations from the yoga intervention; (2) course structure and implementation; (3) perceptions and effects of the intervention; (4) differences between the study yoga intervention and other physical activities. The superordinate theme regarding effects of intervention included aspects of intervention at multiple levels such as emotional, physical, behavioral and spiritual.

CONCLUSIONS

This qualitative study provides valuable insight regarding CRC survivors' expectations and experiences following a 10-week yoga intervention. While expectations varied from skepticism to specific symptom improvement, the majority of participants had a positive, open attitude towards yoga. Consistent with participants' experiences, yoga may represent a promising intervention for CRC survivors if the groups' specific concerns are taken into account.

Experiences of young adults affected by cancer within an 8-week yoga intervention delivered by videoconference: a qualitative interview study

BACKGROUND

Yoga may reduce negative cancer- and treatment-related effects and help improve a range of outcomes, including flexibility, mindfulness, and quality of life among adults affected by cancer. Yet there is little evidence for the role of yoga among young adults (18-39 years) affected by cancer.

PURPOSE

The purpose of this study was to explore the experiences of young adults affected by cancer in an 8-week yoga intervention delivered by videoconference.

METHODS

Young adults who were diagnosed with cancer between the ages of 18 and 39 years, at any stage of the cancer trajectory, who were living in Canada, and who completed an 8-week yoga intervention were approached to complete a semi-structured interview. A social constructivist paradigm was adopted. Interviews were transcribed verbatim and analyzed using reflexive thematic analysis.

RESULTS

Twenty-eight young adults (Mean age = 34.67 ± 5.11 years; n = 25 female) with varied cancer diagnoses participated. Participants' perspectives were represented across 6 themes: (1) I was juggling a number of challenges and changes throughout the yoga intervention; (2) I noticed some improvements in my mental and physical health; (3) I made time to discover new strategies to take care of myself; (4) I was able to see what my body is capable of; (5) I was held accountable and I appreciated that, and; (6) I was able to be around similar others in a safe (virtual) space.

CONCLUSIONS

Findings suggest that an 8-week yoga intervention may offer some benefits for young adults affected by cancer. Self-care, self-compassion, mindfulness, feelings of physical competence, establishing a routine, and being around similar others were viewed as important components of the intervention and may have contributed to the benefits experienced. Findings underscore the potential utility of yoga as a supportive care intervention for young adults affected by cancer.

Lifestyle and integrative oncology interventions for cancer-related fatigue and sleep disturbances

Fatigue, insomnia and sleep disturbances are common after cancer diagnosis, and have a negative impact on quality of life and function. This narrative review synthesised evidence on lifestyle and integrative oncology interventions for cancer-related fatigue, insomnia and sleep disturbances in cancer survivors. There is strong evidence in support of aerobic and strength exercise for the relief of cancer-related fatigue. Yoga, massage therapy, acupuncture, Tai Chi and qigong can also be recommended for cancer-related fatigue. The evidence on yoga, acupuncture and massage therapy for sleep disturbances in cancer is mixed, while exercise appears to have a modest favourable effect. There is insufficient evidence on nutrient supplements or dietary interventions for cancer-related fatigue or insomnia and other sleep disturbances after cancer. Beyond alleviating cancer-related fatigue and insomnia-related symptoms, integrative oncology and lifestyle interventions have potential to effect multiple other benefits, such as improvement in symptoms such as pain and menopausal symptoms. There is a need for well-designed randomised controlled trials of interventions, particularly in the areas of diet and nutrient supplements, and for implementation studies of interventions already supported by evidence.

Empowering mind-body wellness: effect of bundling seated exercises and psychoeducational rehabilitation using the teach-back approach on fatigue and coping of women postmastectomy

BACKGROUND

Being diagnosed with Breast Cancer (BC) is a crisis that throws the patient's life out of balance. Cancer-related fatigue is a debilitating sign experienced by women during and after BC treatment. Regular physical exercise may help mitigate patients' fatigue, enhance coping abilities, improve their quality of life, and overall well-being. In parallel, psychological interventions are geared toward normalizing the lived painful experiences among oncology patients.

OBJECTIVE

to examine the effect of bundling seated exercises and psychoeducational rehabilitation using the teach-back approach on fatigue and coping of women postmastectomy.

METHODS

A quasi-experimental study was conducted in the Oncology Surgical Department and chemotherapy unit at the Alexandria Main University Hospital, Egypt. A total of 60 women were randomly allocated to either to the study or the control groups. Women in the study group practiced seated exercises and psychological rehabilitation interventions, including mindfulness breathing, problem-solving training, cognitive reframing technique, and thought stopping while the control group received the routine care.

RESULTS

The study revealed a significant decline in the fatigue mean scores among participants in the intervention group from 136.10 ± 27.76 to 98.43 ± 25.99 (p < 0.001). Similarly, there was a significant decrease in the patients' mean scores of maladaptive coping, helplessness/ hopelessness (p = 0.014), and anxious preoccupation (p = 0.008). In contrast, there is a noticeable increment in the scores of adaptive coping, such as fighting spirit (p = 0.012), cognitive avoidance (p = 0.002), and fatalism (p = 0.009).

CONCLUSION

Bundling seated exercises and psychological rehabilitation interventions using the teach-back approach have been proven to be simple and inexpensive non-pharmacological methods of reducing cancer-related fatigue and improving coping skills among women post-mastectomy.

Effect of yoga as a complementary therapy in prostate cancer survivors: a systematic review

PURPOSE

Currently, available evidence suggests a positive impact of yoga on physical and psychological well-being in patients across different types of cancer, especially breast cancer survivors. However, there are no available systematic reviews on the effects of yoga on male prostate cancer survivors. The objective of the current systematic review is to specifically examine the quality of life, feasibility, and other effects of yoga on prostate cancer survivors.

METHODS

Bibliographic databases such as PubMed/Medline, CINAHL, EMBASE, Cochrane Library, and Google Scholar were searched for studies that were conducted till December 2022 to assess the effect of yoga on prostate cancer survivors. Studies that met predefined eligibility criteria were included. The quality of the included studies was assessed by the Cochrane risk of bias tool, and for single-arm studies, the Newcastle-Ottawa Scale was used.

RESULTS

A comprehensive literature search yielded a total of 137 studies. After careful consideration, this review included five studies involving 129 prostate cancer survivors. The included studies were published between 2012 and 2022. This systematic review observed that yoga has the potential to enhance erectile function, reduce fatigue and urinary symptoms, alleviate psychological stress, boost immune function, and improve the overall quality of life in prostate cancer survivors. Furthermore, it demonstrates the feasibility of incorporating yoga into their regular routine.

CONCLUSIONS

Yoga could be an effective complementary therapy in the management of physical and psychological symptoms experienced by prostate cancer survivors. However, until more comprehensive evidence becomes available, it would be premature to draw definitive conclusions about the effectiveness of yoga in the context of prostate cancer (PCa).

Yoga as a Therapeutic Intervention in Cancer Care: An Umbrella Review of Systematic Reviews and Meta-Analyses

The therapeutic efficacy of yoga in cancer care has increasingly attracted attention due to the imperative to address the physical and psychosocial obstacles encountered by cancer patients. Despite previous research presenting conflicting findings on the effectiveness of yoga, there is a need for a comprehensive review to consolidate existing evidence and identify commonalities across studies. An umbrella review was undertaken to aggregate and analyse findings from multiple systematic reviews and meta-analyses on the role of yoga in cancer care. Relevant literature was identified through searches on the Web of Science, Cochrane Library, PubMed, and Scopus databases, using a combination of MeSH (Medical Subject Headings) terms and free-text terms with Boolean operators. The quality of the included reviews was evaluated using the AMSTAR-2 tool to ensure the reliability and validity of the discussed findings. The outcomes revealed a predominance of favourable results associated with yoga interventions, particularly in enhancing psychosocial well-being and the quality of life among cancer patients. Consistent reports indicated significant reductions in symptoms such as anxiety, depression, and stress, as well as enhancements in physical outcomes such as fatigue and sleep quality. However, variations in the efficacy of yoga were observed and were dependent on the type of intervention, patient adherence, and comparative analyses with other forms of exercise. While the benefits were substantial in the short term, they did not uniformly surpass those of other therapeutic exercises in the medium term. Despite yoga demonstrating significant immediate benefits in managing both the physical and psychological symptoms associated with cancer, the variability in its long-term and comparative effectiveness suggests the necessity for personalised approaches. The findings emphasise the importance of considering individual patient needs and treatment contexts when integrating yoga into cancer care protocols. Future research should focus on identifying the optimal conditions under which yoga is most beneficial to tailor interventions for enhanced therapeutic efficacy.

Health benefits of yoga for cancer survivors: An updated systematic review and meta-analysis

Objective

To evaluate the effects of yoga on health-related outcomes [i.e., physical function, mental health, and overall quality of life (QOL)] of cancer survivors via a systematic review and meta-analysis of randomized controlled trials (RCTs) over the past 5 years across cancer types.

Methods

An updated systematic review and meta-analysis was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses. RCTs published from January 1, 2018, to February 23, 2023, were searched in five English databases (PubMed, The Cochrane Library, ISI, PsycINFO, and CINAHL), three Chinese databases (Wan Fang, China National Knowledge Infrastructure, and Chinese Biomedical Literature Database), and three English clinical trials registry platforms (International Clinical Trials Registry Platform, ClinicalTrials.gov, and EU Clinical Trials Register).

Results

A total of 34 RCTs were included in this updated review. Yoga benefited the physical function, mental health, and overall QOL of cancer survivors. The effect size of yoga for most physical and mental health-related outcomes was relatively small, but that for the QOL was generally large. The impact of yoga on the QOL of cancer survivors ranged from moderate to high.

Conclusions

Yoga has health benefits for cancer survivors and could therefore be used as an optional supportive intervention for cancer-related symptom management.

Non-pharmacological interventions for chemotherapy-induced diarrhoea and constipation management: A scoping review

PURPOSE

Chemotherapy-induced diarrhoea (CID) and constipation (CIC) are among the most common and severe gastrointestinal symptoms related to chemotherapy. This review aimed to identify and describe the evidence for non-pharmacological interventions for the management of CID and CIC.

METHODS

The scoping review was based on the Joanna Briggs Institute methodology and reported in line with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews checklist. Evidence from five databases were included: CINAHL, MEDLINE, Embase, PubMed, and APA PsycInfo. Data were systematically identified, screened, extracted and synthesised narratively to describe the evidence for non-pharmacological interventions and their effects on CID and CIC.

RESULTS

We included 33 studies, of which 18 investigated non-pharmacological interventions for CID management, six for CIC management, and nine for both CID and CIC management. Interventions were categorized into five groups, including (1) digital health interventions, (2) physical therapies, (3) diet and nutrition therapies, (4) education, and (5) multimodal. Diet and nutrition therapies were the most common to report potential effectiveness for CID and CIC outcomes. Most of the interventions were implemented in hospitals under the supervision of healthcare professionals and were investigated in randomised control trials.

CONCLUSIONS

The characteristics of non-pharmacological interventions were diverse, and the outcomes were inconsistent among the same type of interventions. Diet and nutritional interventions show promise but further research is needed to better understand their role and to contribute to the evidence base. Nurses are well placed to assess and monitor for CIC and CID, and also deliver effective non-pharmacological interventions.

The Effect of Psychoeducational Interventions on Cancer-Related Fatigue: A Systematic Review and Meta-analysis of Randomized Controlled Studies

BACKGROUND

Cancer-related fatigue is one of the most common symptoms of cancer patients. Psychoeducation is often used in the management of cancer-related fatigue.

OBJECTIVE

The aim of this study was to synthesize the effects of psychoeducational interventions on cancer-related fatigue.

METHODS

This article is a systematic review and meta-analysis of randomized controlled studies. The 11 electronic databases were searched, and studies using psychoeducational interventions to manage cancer-related fatigue were included. Data synthesis was performed using Comprehensive Meta-Analysis software version 3.0. The random-effects model was used to pool the effect size for intervention. The subgroup analysis was conducted to investigate the effect of the characteristics of psychoeducational interventions. This study was reported according to the Cochrane Handbook for Systematic Reviews of Intervention version 6.3 and the Preferred Reporting Items for Systematic Reviews and Meta-Analyses 2020 guidelines.

RESULTS

This analysis included 10 studies with a total of 1369 participants. Most of the included studies compared the psychoeducational intervention group with the passive control group. Our meta-analysis revealed that psychoeducational intervention has a positive medium effect on improving cancer-related fatigue with a low quality of evidence. Subgroup analyses indicated no difference between group and individual interventions, between face-to-face and digital interventions, or between ≤3 and >3 sessions.

CONCLUSIONS

Psychoeducational interventions can improve cancer-related fatigue. Additional well-designed randomized controlled studies are needed to upgrade the quality of evidence for psychoeducational interventions on cancer-related fatigue.

IMPLICATIONS FOR PRACTICE

Nurses may practice psychoeducational interventions to manage cancer-related fatigue and may use this study design for randomized controlled studies for psychoeducational interventions on cancer-related fatigue.

Development and Implementation of a Culturally Informed Spanish Language Yoga Program for Latiné Women With Overweight or Obesity Diagnosed With Cancer: A Single Arm Pilot Study

Background

Given limited yoga research in health disparities populations, we developed and evaluated a 12-week Spanish language yoga program for Latiné women with overweight or obesity affected by cancer. The program aimed to empower participants through culturally tailored yoga practice and opportunities for social connection and support.

Methods

Partnering with a community-based organization, the program was co-created by bilingual (English and Spanish-speaking) yoga instructors, Latiné cancer survivor support professionals, and integrative medicine researchers. The single arm intervention consisted of 12 separate, 60-minute Hatha yoga classes, including physical postures, breathing exercises, culturally relevant poetry, and post-practice socialization opportunities. Measures were administered at baseline, 12-week, and 24-week.

Results

Thirty-five eligible participants enrolled in the program, demonstrating high feasibility and relevance as well as high levels of engagement in home practice. Some participants faced barriers to regular home practice, including family responsibilities and concerns about proper pose execution. Preliminary outcome analyses indicated improvements in sleep disturbance, pain interference, depression, and blood pressure post-intervention, with sustained improvements in depression, anxiety, and blood pressure at 24-week. No significant changes were observed in fatigue, physical function, positive affect, satisfaction with social roles and activities, and weight. Structured post-practice social snack time with yoga instructors (compared with unstructured time with peers) was associated with self-reported improvements in satisfaction with social roles and activities and weight loss.

Conclusion

This yoga program successfully engaged female Latiné cancer survivors with overweight and obesity and serves as a foundational step in empowering this population to improve their health and well-being through culturally tailored yoga practice. Future research should utilize controlled study designs and engage participants from different geographical regions to study the efficacy and sustainability of findings.

Baduanjin Mind-Body Exercise for Cancer-Related Fatigue: Protocol for a Remotely Delivered Randomized Wait-List Controlled Feasibility Study

BACKGROUND

People living with a cancer diagnosis often experience cancer-related fatigue (CRF). Between 9% and 45% of people report CRF as moderate to severe, negatively impacting their quality-of-life (QOL). The evidence-base for managing CRF recommends exercise-related therapies over pharmaceutical interventions. One such exercise-like therapy is Baduanjin mind-body exercise (MBE), which has additional benefits. A remotely delivered program may further benefit people with CRF. The primary objective of this pilot will test study feasibility of a remotely delivered Baduanjin MBE exercise program for people living with CRF.

METHODS

This is a randomized wait-list controlled pilot study and will take place in Sydney, Australia. Subject to informed consent, 40 adults with moderate CRF levels and receiving or previously received adjuvant chemotherapy, will undertake a home-based 8-week Baduanjin MBE program supported by online resources and instructors. The primary feasibility outcomes are recruitment, enrollment, retention, and adherence rates; and safety as measured by tolerance and adverse-event frequency. Clinical outcomes (eg, changes in CRF, QOL, and participant perceptions) are assessed at pre-intervention, week 1, week 4, week 8, and post-intervention. Analyses follows the Intent-to-Treat (all participants as per randomization) and per-protocol (participants adhering to the protocol). Missing data will be imputed from previous data entries and regression models may be tested to predict missing outcomes.

DISCUSSION

To our knowledge, this is the first study evaluating the feasibility and effects of Baduanjin MBE on CRF using a remote delivery method. These feasibility data will inform a fully powered future trial investigating evidence of effect on CRF and QOL.Trial registration: Australian and New Zealand Clinical Trials Registry (ANZCTR 12623000177651).Ringgold ID: 651498 Chinese Medicine Centre.

No effects were found in favor of Hatha or Iyengar yoga exercises for improving cancer-related fatigue, depression symptoms, or quality of life: a systematic review with meta-analysis and metaregression

OBJECTIVE

To summarize the evidence on the effectiveness of Hatha or Iyengar yoga exercises on cancer-related fatigue, depression symptoms, and the overall quality of life in adults with cancer.

METHODS

A systematic review with meta-analysis was conducted. The CINAHL (via EBSCOhost), Embase, PubMed, and SPORTDiscus (via EBSCOhost) databases were searched from inception to 7th November 2022. Clinical trials evaluating cancer-related fatigue, depression symptoms, and the overall quality of life were included. The risk of bias was assessed using the Cochrane Risk of Bias tool 2. The Template for Intervention Description and Replication (TIDieR) checklist was used to check if the interventions reviewed were described in detail to be implemented in the clinical setting. The Grading of Recommendations, Assessment, Development, and Evaluations approach was used to rate the certainty of evidence. Meta-regressions, sensitivity analyses, and subgroup meta-analyses were conducted to explore sources of heterogeneity.

RESULTS

Eleven studies were included (N = 777 participants). Overall, Hatha, Iyengar, and the combination of both yoga styles did not improve any of the outcomes of interest. In addition, five studies had a high risk of bias, and six studies had some concerns about biases. Weaknesses in reporting modifications during the development of the study were observed (TIDieR item 10). The certainty of evidence ranged from low to very low across the outcomes.

CONCLUSIONS

We could not make sound clinical recommendations with the current quality of the findings.

Effects of Yoga on Cancer-Related Fatigue, Psychological Distress, and Quality of Life Among Patients With Cancer Undergoing Chemotherapy and/or Radiotherapy: A Systematic Review and Meta-analysis

BACKGROUND

Yoga can be considered supportive therapy for patients with cancer to alleviate cancer-related symptoms. However, there has been no meta-analysis examining yoga's effects among patients with cancer undergoing chemotherapy and/or radiotherapy.

OBJECTIVE

To synthesize the evidence regarding the effects of yoga on improving cancer-related fatigue, psychological distress, and quality of life among patients with cancer undergoing chemotherapy and/or radiotherapy.

METHODS

Ten English databases and 2 Chinese databases were searched from inception to December 2022. Two independent reviewers screened studies and extracted the data. Randomized controlled trials examining the effects of yoga on cancer-related fatigue, psychological distress, and quality of life were included. Meta-analysis was conducted, and narrative synthesis was performed when meta-analysis was not applicable.

RESULTS

Fourteen studies from 16 articles were included. The results showed that yoga reduced cancer-related fatigue (standardized mean difference [SMD], -0.75; 95% confidence interval [CI], -1.12 to -0.38; P < .001), anxiety (SMD, -0.91; 95% CI, -1.68 to -0.14; P = .02), but not depression (SMD, -0.82; 95% CI, -1.67 to 0.04; P = .06). The effects of yoga on distress and quality of life were inconclusive.

CONCLUSIONS

Yoga significantly helped reduce cancer-related fatigue and anxiety but did not reduce depression among patients with cancer undergoing chemotherapy and/or radiotherapy. Further rigorous studies are needed to identify the optimal characteristics of yoga for these patients.

IMPLICATIONS FOR PRACTICE

It is possible to recommend yoga to patients with cancer undergoing chemotherapy and/or radiotherapy for managing cancer-related fatigue and anxiety after duly considering patients' physical conditions and ensuring appropriate instructions are given.

The Effects of Complementary Therapies on Patient-Reported Outcomes: An Overview of Recent Systematic Reviews in Oncology

Many patients with cancer make use of complementary medicine alongside conventional medicine, but clinicians in oncology often lack the knowledge to adequately advise patients on the evidence base for complementary therapies. This study aims to provide an overview of recently published systematic reviews that assess the effects of complementary therapies on patient-reported health outcomes in patients with cancer. Systematic reviews, including a meta-analysis of at least two randomized controlled trials, were identified from the PubMed, Embase, Cochrane Library, CINAHL and PsycINFO databases. The methodological quality was assessed with AMSTAR 2. One hundred systematic reviews were included. The results suggest that several complementary therapies can improve health outcomes reported by patients with cancer, such as acupuncture to relieve pain, music interventions to reduce anxiety and yoga to improve cancer-related fatigue. The side effects related to complementary therapy use are generally mild. The results remain inconclusive for some intervention-outcome combinations. Many of the included systematic reviews insufficiently assessed the causes and impact of bias in their interpretation of the results. This overview of systematic reviews can support clinicians in counselling their patients on this topic and provide directions for future research and clinical practice guidelines in the field of complementary medicine.

Qualitative similarities and distinctions between participants' experiences with a yoga intervention and an attention control

PURPOSE

This manuscript aims to compare and contrast acceptability and perceived benefits of yoga-skills training (YST) and an empathic listening attention control (AC) in the Pro-You study, a randomized pilot trial of YST vs. AC for adults receiving chemotherapy infusions for gastrointestinal cancer.

METHODS

Participants were invited for a one-on-one interview at week 14 follow-up, after completing all intervention procedures and quantitative assessments. Staff used a semi-structured guide to elicit participants' views on study processes, the intervention they received, and its effects. Qualitative data analysis followed an inductive/deductive approach, inductively identifying themes and deductively guided by social cognitive theory.

RESULTS

Some barriers (e.g., competing demands, symptoms), facilitators (e.g., interventionist support, the convenience of clinic-based delivery), and benefits (e.g., decreased distress and rumination) were common across groups. YST participants uniquely described the importance of privacy, social support, and self-efficacy for increasing engagement in yoga. Benefits specific to YST included positive emotions and greater improvement in fatigue and other physical symptoms. Both groups described some self-regulatory processes, but through different mechanisms: self-monitoring in AC and the mind-body connection in YST.

CONCLUSIONS

This qualitative analysis demonstrates that participant experiences in a yoga-based intervention or an AC condition reflect social cognitive and mind-body frameworks of self-regulation. Findings can be used to develop yoga interventions that maximize acceptability and effectiveness and to design future research that elucidates the mechanisms by which yoga is efficacious.

Meditation and Yoga for Irritable Bowel Syndrome: A Randomized Clinical Trial

INTRODUCTION

Delivered in person, yoga is effective in managing irritable bowel syndrome (IBS) symptoms. The evidence for efficacy, feasibility, and safety of virtually delivered yoga for patients with IBS is unknown.

METHODS

Adults diagnosed with IBS were randomized to either Hatha yoga intervention of 8 weekly online classes delivered virtually or an advice-only control group and assessed at baseline and postintervention. We used an unadjusted ANOVA to determine differences between and within groups on the primary outcome (decrease of ≥50 points in IBS Symptom Severity Scale [IBS-SSS]) and secondary outcomes (quality of life, anxiety and depression, fatigue, somatic symptoms, perceived stress, COVID-19 stress, and self-compassion). We assessed feasibility through recruitment and attrition rates, adherence, participant satisfaction, and safety (i.e., adverse events).

RESULTS

Seventy-nine people participated (mean age 45.4 years [SD = 14.0], 92% women, 20% attrition rate). IBS-SSS decreased significantly in the treatment group (Δ change = 54.7, P = 0.028), but not in the control group (Δ change = 22.6, P = 0.277). Fourteen patients (37%) in the yoga group reached a clinically relevant decrease of ≥50 points on the IBS-SSS postintervention compared with 8 patients (20%) in the control group ( P = 0.242). No significant difference was found between groups in IBS-SSS score postintervention ( P = 0.149), but significant differences in favor of the treatment group for quality of life ( P = 0.030), fatigue ( P = 0.035), and perceived stress ( P = 0.040) were identified. The yoga program demonstrated feasibility. Intention to practice yoga decreased significantly in both groups from baseline to postintervention ( P < 0.001). However, the decline in intention did not correlate with practice minutes.

DISCUSSION

Virtually delivered yoga is safe and feasible, and effective in reducing IBS symptoms. Based on the primary end point, the intervention was not superior to an advice-only control group.

The Role of Complementary and Alternative Medicine on Cancer-Related Fatigue in Adults: An Overview of Systematic Reviews

BACKGROUND

Cancer-related fatigue (CRF) has an enormous adverse impact on quality of life and subsequent therapy of cancer patients. Complementary and alternative medicine (CAM) is reported to improve CRF in many systematic reviews (SRs), but the effects are controversial because of variations in the quality and outcomes.

METHODS

Thirteen databases were searched from inception to September 2022. Only SRs of randomized controlled trials (RCTs) were included. We assessed the quality of included SRs with the AMSTAR-2 tool, the strength of evidence with the GRADE system, the risk of bias with the ROBIS tool, and the integrity of SRs with the PRISMA checklist.

RESULTS

We included 30 eligible SRs (27 meta-analyses). Based on the AMSTAR-2 tool, 29 SRs were rated as "critically low" quality, and only one was rated as "low" quality. With the ROBIS tool, 19 SRs demonstrated a low risk of bias. According to the PRISMA checklist, no SRs reported all the items, and 10 SRs sufficiently reported over 70%. Based on the GRADE system, 7 outcomes were assessed as high-quality evidence.

CONCLUSION

This overview demonstrates promising evidence for the effectiveness of CAM interventions in the treatment of CRF in adults. The roles of qigong, music, auricular point therapy, and dietary supplements in CRF need further evaluation. Although findings are mixed, it is recommend to select appropriate CAM to manage cancer-related fatigue under the guidance of physicians. More studies with rigorous methodological designs and sufficient sample sizes are needed.

Psycho-oncology interventions focusing on fatigue and sleep disturbances

PURPOSE OF REVIEW

Cancer-related fatigue (CRF) and sleep disturbances are common symptoms among patients with cancer. They are often conceptualized as a part of a larger symptom cluster, also comprising pain and emotional distress. Despite their prevalence and long-lasting effects, CRF and sleep disturbances are still poorly addressed in clinical settings. Specific interventions are needed to manage these symptoms.

RECENT FINDINGS

In addition to conventional pharmacological therapies, other kinds of interventions are increasingly being developed in oncology. This review will discuss three categories of interventions for patients with cancer and their interest in alleviating CRF and sleep disturbances: physical exercises (e.g., aerobic, resistance training, running, free weights), psychological interventions (e.g., cognitive-behavioural therapy, psychoeducational interventions), and mind-body interventions (e.g., yoga, mindfulness, hypnosis). The multicomponent aspect of these interventions seems particularly important to address these symptoms.

SUMMARY

The findings detailed in this review will allow the scientific community, as well as health professionals working in oncology settings, to be informed about new nonpharmacological therapeutic options to help patients to manage their symptoms. It could eventually help to improve existing interventions for these patients.

Meta-Analysis of Randomized Controlled Trials on Yoga, Psychosocial, and Mindfulness-Based Interventions for Cancer-Related Fatigue: What Intervention Characteristics Are Related to Higher Efficacy?

Simple Summary

Many individuals with cancer suffer from persistent exhaustion due to cancer therapy, known as cancer-related fatigue (CRF). Yoga, psychosocial, and mindfulness-based interventions are recommended to reduce CRF. However, it is not clear yet how interventions need to be designed to maximize their efficacy. This meta-analysis aimed to identify intervention characteristics associated with greater reductions in CRF. A total of 70 interventions with 6387 participants were included in the analysis. Our results found a positive effect of yoga, psychosocial, and mindfulness-based interventions, while all invention types revealed large differences in intervention effects. In psychosocial interventions, using a group setting and working on cognition was related to higher efficacy. Regarding yoga and mindfulness-based interventions, no specific intervention characteristics emerged as more favorable than others. Overall, this meta-analysis suggests opportunities to optimize psychosocial interventions for CRF, whereas the design of yoga and mindfulness-based interventions seems to allow for variation.

Abstract

Cancer-related fatigue (CRF) is a burdensome sequela of cancer treatments. Besides exercise, recommended therapies for CRF include yoga, psychosocial, and mindfulness-based interventions. However, interventions conducted vary widely, and not all show a significant effect. This meta-analysis aimed to explore intervention characteristics related to greater reductions in CRF. We included randomized controlled trials published before October 2021. Standardized mean differences were used to assess intervention efficacy for CRF and multimodel inference to explore intervention characteristics associated with higher efficacy. For the meta-analysis, we included 70 interventions (24 yoga interventions, 31 psychosocial interventions, and 15 mindfulness-based interventions) with 6387 participants. The results showed a significant effect of yoga, psychosocial, and mindfulness-based interventions on CRF but with high heterogeneity between studies. For yoga and mindfulness-based interventions, no particular intervention characteristic was identified to be advantageous for reducing CRF. Regarding psychosocial interventions, a group setting and work on cognition were related to higher intervention effects on CRF. The results of this meta-analysis suggest options to maximize the intervention effects of psychosocial interventions for CRF. The effects of yoga and mindfulness-based interventions for CRF appear to be independent of their design, although the limited number of studies points to the need for further research.

Tele-Yoga in Long Term Illness-Protocol for a Randomised Controlled Trial Including a Process Evaluation and Results from a Pilot Study

BACKGROUND

For people with long-term illness, debilitated by severe symptoms, it can be difficult to attend regular yoga classes. We have therefore developed a tele-health format of yoga that can be delivered in the home. The tele-yoga was co-designed with members of a patient-organisation, yoga-instructor, and IT-technician. It includes live-streamed group-yoga sessions twice a week and an app with instructions on how to self-perform yoga.

AIM

To describe a study protocol for a randomised controlled trial (RCT) including a process evaluation and report on a pilot study evaluating method- and intervention-related components including feasibility, safety, and efficacy.

METHODS

Ten participants with heart failure aged between 41-76 years were randomised to tele-yoga (n = 5) or to the control group (n = 5). In the pilot study recruitment, enrolment, randomisation, and data collection of all outcomes including primary, secondary and process evaluation measures were tested according to the study protocol. Fidelity, adherence and acceptability to the tele-yoga group training and app use was determined. Safety was assessed by adverse events.

RESULTS

The pilot revealed that the methodological aspect of the protocol worked sufficiently in all aspects except for missing data in the physical test of two participants and one participant in the control-group that dropped out of the study at three months follow-up. The tele-yoga training did not lead to any adverse events or injuries, adherence of tele-yoga was sufficient according to preset limits. The tele-yoga intervention also showed some favourable trends of improvements in the composite-end point compared to the active control group. However, since data only was presented descriptively due to the small sample size, the impact of these trends should be interpreted carefully.

CONCLUSION

Our pilot study showed promising results in feasibility, safety, and acceptability of the tele-yoga intervention. Some changes in the protocol have been made to decrease the risk of missing data in the measures of physical function and in the full-scale RCT now ongoing the results of the sample size calculation for 300 participants have included the estimated level of drop outs and missing data.
