Yoga, breast cancer-related lymphoedema and well-being: A descriptive report of women's participation in a clinical trial

The Effects of Online Yoga Practice on Cancer Patients: A Systematic Review

Background: Cancer remains a leading cause of death, with 9.7 million deaths in 2022. Despite advancements in diagnosis and treatment, many cancer patients experience side effects that significantly impact their quality of life, including chronic pain, anxiety, depression, sleep disturbances, and cancer-related fatigue. Non-pharmacological interventions, such as yoga, have gained attention for their potential to reduce stress and improve overall well-being. However, barriers such as fatigue, pain, and transportation issues limit access to in-person yoga, leading to the growing adoption of online yoga as a viable alternative. Objective: This systematic review synthesizes research on the effectiveness of online yoga for cancer patients. A comprehensive search was conducted across Medline, PsycINFO, and Scopus databases on 24 October 2024. The methodological quality of the studies was assessed using the CASP Checklist. Of 6266 articles initially identified, 14 studies met the inclusion criteria, comprising qualitative (n = 4) and quantitative (n = 10) studies. Results: The results suggest that online yoga can improve stress and sleep quality, with moderate effects on anxiety, depression, and fatigue. However, variability in study designs and methodological limitations complicate the evaluation of its overall effectiveness. Conclusions: Online yoga offers a practical, accessible option for cancer patients unable to attend in-person sessions, showing the potential to enhance mental and physical health outcomes. Nevertheless, the variability in study methodologies highlights the need for more standardized research to establish its role as a supportive intervention in oncology care.

Effects of a tailor-made yoga program on upper limb function and sleep quality in women with breast cancer: A pilot randomized controlled trial

Purpose

Upper limb dysfunction and sleep disturbance are common and serious health problems in women with breast cancer. Yoga is a mind-body intervention which is shown to improve physical and psychological health. The aim of this study is to evaluate the effectiveness of a tailor-made yoga program on upper limb function and sleep quality in women with breast cancer.

Methods

A pilot randomized controlled trial (RCT) study design was used. Participants were randomly allocated to either the yoga intervention group (YG; eight weekly 60-min group-based yoga sessions) or the wait-list control group (CG). The primary outcome measures were upper limb function and sleep quality, which were assessed by the self-reported questionnaires - the shortened version of the Disabilities of the Arm, Shoulder and Hand (QuickDASH) and the Pittsburgh Sleep Quality Index (PSQI), respectively. The secondary outcome measures were upper limb muscle strength and mobility, heart rate variability (HRV), anxiety and depression, fatigue, and health-related quality of life. All participants underwent assessment at four time-points (baseline, mid-intervention, post-intervention, and 1-month follow-up). The effectiveness of the intervention was tested by two-way mixed-design repeated-measures analysis of covariance.

Results

For the primary outcomes, there was no significant between-group difference in the upper limb function. The YG demonstrated significantly shorter sleep latency and higher HRV, and less sleep disturbance than the CG at post-intervention, and 1-month follow-up, respectively. For the secondary outcomes, the YG demonstrated significantly improved shoulder muscle strength and arm symptoms compared to the CG from mid-intervention until the 1-month follow-up.

Conclusion

This pilot trial revealed that the yoga program was feasible to be implemented for women with primary stage breast cancer. Although yoga was not found to be effective in improving the upper limb function, it improved sleep latency, HRV, shoulder muscle strength and arm symptoms of women with breast cancer.

Experiences of Irritable Bowel Syndrome Patients in a Virtual Yoga Program: Qualitative Findings from a Clinical Trial

BACKGROUND AND AIMS

In-person yoga interventions have shown feasibility and effectiveness in improving the outcomes of patients with irritable bowel syndrome (IBS), but experiences in virtual yoga interventions have not been examined. This study aimed to explore patients' experiences of a virtually delivered yoga intervention for IBS.

METHODS

An embedded qualitative substudy was included in a randomized controlled trial examining the feasibility and effectiveness of a virtual yoga program among adult patients with IBS. Semi-structured interviews captured participants' past and current experiences, program satisfaction, perceived impact on IBS symptoms and overall physical and mental health, facilitators and barriers to participation, perceptions of social support and supervised learning, and input on improving future programming. Data were coded and analyzed in duplicate using NVivo 12. An analytic template based on the interview guide was developed and thematic analysis identified themes, as well as the relationship between themes and subthemes.

RESULTS

Among the 14 participants (all female, mean age 47.7 years), three major themes were identified: (1) positive experience in the yoga program, (2) incorporating yoga into IBS management post-study, and (3) recommendations for program improvement.

CONCLUSION

Patients with IBS experience in a virtual yoga program was positive with improvements in physical and mental health outcomes. Considering the barriers and facilitators to participating in an online yoga program along with participant recommendations may improve future intervention design and delivery to increase self-efficacy and confidence among patients with IBS.

Women's experiences with yoga after a cancer diagnosis: a qualitative meta-synthesis-part I

BACKGROUND

Qualitative research on women's experiences participating in yoga after a cancer diagnosis is growing; systematic synthesis and integration of results are necessary to facilitate the transfer and implementation of knowledge among researchers and end-users. Thus, the purpose of this meta-synthesis was to: (1) integrate findings from qualitative studies, (2) compare and contrast findings to elucidate patterns or contradictions in conclusions, and (3) develop an overarching interpretation of women's experiences participating in yoga after a cancer diagnosis.

METHODS

Using meta-study methodology, six electronic databases were searched using a sensitive search strategy in November 2020, a supplemental scan of reference lists was conducted in August 2021, and the database search was replicated in October 2021. Two reviewers independently screened titles/abstracts and full-texts to determine eligibility.

RESULTS

The searches yielded 6804 citations after de-duplication. Data from 24 articles meeting the eligibility criteria were extracted, and the results, methods, and theoretical approach(es) were analyzed. The analysis revealed that there was a predominant focus on two focal points in the primary articles: (1) women's well-being and quality of life (QoL; part I) and (2) intervention preferences (part II). Five overarching categories emerged related to well-being and QoL: (1) yoga can support improvements in multiple dimensions of QoL in women diagnosed with cancer, (2) women diagnosed with cancer experience an interaction between QoL dimensions, (3) elements of yoga that support improvements in QoL dimensions, (4) breathwork and meditation are integral elements of yoga, and (5) yoga practice may support lifestyle behavior change. The articles reviewed had notable limitations related to: (1) reporting about instructor(s), content of the intervention, and environmental characteristics of the setting, (2) identifying and incorporating optimal features in the intervention design, (3) incorporating theory and real-world considerations into the study procedures, and (4) including positive and negative conceptualizations of QoL as an interconnected and multidimensional concept.

CONCLUSION

Moving forward, it remains critical to identify the ideal structure and content of yoga programs for promoting well-being and QoL among women diagnosed with cancer, as well as to explore barriers and facilitators to sustainable program implementation.

An Exploration of Rural-Urban Residence on Self-Reported Health Status with UK Cancer Survivors Following Treatment: A Brief Report

Objective: To explore the effect of rural−urban residence on the self-reported health status of UK cancer survivors following primary treatment. Design: A post-positivist approach utilizing a cross-sectional survey that collected data on demographics, postcode and self-reported health status. Methods: An independent samples t test was used to detect differences in health status between rural and urban respondents. Pearson’s χ2 was used to control for confounding variables and a multivariate analysis was conducted using Stepwise linear regression. Setting: East Midlands of England. Participants: Adult cancer survivors who had undergone primary treatment in the last five years. Participants were excluded if they had recurrence or metastatic spread, started active oncology treatment in the last twelve months, and/or were in receipt of palliative or end-of-life care. Main outcome: Residence was measured using the UK Office for National Statistics (ONS) RUC2011 Rural−Urban Classifications and Health Status via the UK ONS self-reported health status measure. Ethics: The study was reviewed and approved (Ref: 17/WS/0054) by an NHS Research Ethics Committee and the Health Research Authority (HRA) prior to recruitment and data collection taking place. Results: 227 respondents returned a questionnaire (response rate 27%). Forty-five percent (n = 103) were resident in a rural area and fifty-three percent (n = 120) in an urban area. Rural (4.11 ± 0.85) respondents had significantly (p < 0.001) higher self-reported health statuses compared to urban (3.65 ± 0.93) respondents (MD 0.47; 95% CI 0.23, 0.70). Conclusion: It is hoped that the results will stimulate further work in this area and that researchers will be encouraged to collect data on rural−urban residency where appropriate.

Qualitative studies conducted alongside randomized controlled trials in oncology: A scoping review of use and rigour of reporting

BACKGROUND

Randomized controlled trials (RCTs) are the gold standard for generating evidence to inform clinical oncology practice. Knowledge gained through qualitative research methodologies can be complementary to that gained through RCTs. How qualitative research has been combined with RCTs in oncology has not been previously characterized.

OBJECTIVE

This scoping review was conducted to summarize how qualitative research associated with RCTs in the oncology setting has been conducted and examine the quality of reporting.

ELIGIBILITY CRITERIA

Manuscripts reporting on qualitative research linked with RCTs in the cancer context that involved patients (both adult and pediatric) and/or informal caregiver (friends/family) were included.

SOURCES OF EVIDENCE

Peer-reviewed manuscripts indexed in MEDLINE (OVID) and CINAHL, published in English between 2008 and January 2019.

CHARTING METHODS

Formal scoping review methods were followed. A data extraction tool informed by the research questions as well as the COnsolidated criteria for REporting Qualitative research (COREQ) was utilized. Extraction was conducted independently by two authors, with disagreements resolved by a third.

RESULTS

Fifty-four articles were included. Assessing information sharing, diet/exercise, and psychotherapeutic interventions were the most common focuses of the RCTs. The most common focus of the qualitative component was on gaining insight into the experience of receiving the intervention or participating in RCT procedures. How the intervention impacted the cancer experience was not a common focus of the qualitative components. Some reports provided insufficient information to understand how the qualitative components aligned with the RCT components. The results of the qualitative and RCT components were not integrated to draw meaningful conclusions about the efficacy of the intervention under study in most cases. Reports focusing on only qualitative methods had higher median (Mdn) reporting of COREQ items compared to reports that included both the qualitative and RCT components (Mdn = 18 vs. Mdn = 14, respectively; p <0.001).

CONCLUSIONS

This review identified that qualitative research has been combined with RCTs in the cancer context in a number of ways, most commonly to understand the experience of receiving study interventions or participating in trial procedures. Exploring how interventions impact other aspects of the cancer experience is an approach that should be considered in future work. Formalized guidelines for the design and reporting of investigations that combine qualitative and RCT approaches in the cancer context are expected to be of value.

TWEETABLE ABSTRACT

Combining qualitative research with randomized controlled trials in oncology: an impornt opportunity for discovery.

A Qualitative Study Exploring Feasibility and Acceptability of Acupuncture, Yoga, and Mindfulness Meditation for Managing Weight After Breast Cancer

Introduction:

Weight gain is common after breast cancer. Yoga, mindfulness meditation, and acupuncture may assist with managing weight. However, evidence on effectiveness is limited. This study assessed the feasibility and acceptability of recruiting for and implementing a randomized controlled trial (RCT) evaluating these interventions as adjuncts to lifestyle interventions (diet and exercise) for weight management in women with breast cancer.

Methods:

Qualitative study involving virtual focus groups or semi-structured interviews. Participants were recruited via email invitation from a breast cancer consumer organization and breast cancer center in Australia. Eligible participants had received treatment for breast cancer, and were fluent in English. A purposive sample of culturally and linguistically diverse (CALD) participants was also recruited. Focus groups and interviews were audio-recorded, transcribed verbatim and analyzed using thematic analysis with the constant comparison method.

Results:

Emails were sent to 1415 women of which 37 provided data in 5 focus groups and 1 semi-structured interview, including 1 focus group (n = 6) with only women from CALD backgrounds. Yoga and mindfulness meditation were perceived as feasible and acceptable for weight management, but acupuncture was seen to be too invasive to be acceptable. A focus on wellness rather than weight reduction, flexible program delivery, trusted advice, consideration of participant burden and benefit, and peer-support were key factors perceived to increase feasibility and acceptability.

Conclusions:

Yoga and mindfulness meditation are acceptable and useful adjuncts to lifestyle interventions for weight management after breast cancer. This research places end-users at the forefront of trial design, and will inform future trials using these interventions for weight management and improving health and wellbeing after breast cancer.

What is known about the role of rural-urban residency in relation to self-management in people affected by cancer who have completed primary treatment? A scoping review

PURPOSE

Despite wide acknowledgement of differences in levels of support and health outcomes between urban and rural areas, there is a lack of research that explicitly examines these differences in relation to self-management in people affected by cancer following treatment. This scoping review aimed to map the existing literature that examines self-management in people affected by cancer who were post-treatment from rural and urban areas.

METHODS

Arksey and O'Malley's framework for conducting a scoping review was utilised. Keyword searches were performed in the following: Academic Search Complete, CINAHL, MEDLINE, PsycINFO, Scopus and Web of Science. Supplementary searching activities were also conducted.

RESULTS

A total of 438 articles were initially retrieved and 249 duplicates removed leaving 192 articles that were screened by title, abstract and full text. Nine met the eligibility criteria and were included in the review. They were published from 2011 to 2018 and conducted in the USA (n = 6), Australia (n = 2) and Canada (n = 1). None of the studies offered insight into self-managing cancer within a rural-urban context in the UK. Studies used qualitative (n = 4), mixed methods (n = 4) and quantitative designs (n = 1).

CONCLUSION

If rural and urban populations define their health in different ways as some of the extant literature suggests, then efforts to support self-management in both populations will need to be better informed by robust evidence given the increasing focus on patient-centred care. It is important to consider if residency can be a predictor of as well as a barrier or facilitator to self-management.

Feasibility and preliminary efficacy of a hypopressive exercise program on postmenopausal cancer survivors: A pilot study

BACKGROUND

Cancer-related fatigue (CRF) is a common symptom during and after cancer treatment that negatively affects the patient's quality of life. Exercise is one of the most effective non-pharmacological treatments for CRF. Multimodal exercise therapy programs that include hypopressive exercises, relaxation and myofascial release may be beneficial for CRF. The aim of this pilot study was to evaluate the feasibility and efficacy of a multimodal program on CRF and lower limb functional strength in postmenopausal women diagnosed with cancer.

METHODS

7 postmenopausal women (age = 55.28 years; BMI = 26.05 kg/m2) who had a cancer diagnosis participated in a supervised and progressive 55-min class once per week for 12-weeks. CRF was measured using the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-Cancer Related Fatigue 12 and lower limb strength was assessed with the sit and stand test.

RESULTS

No adverse events were reported during the training period and all participants completed the exercise protocol. There was a significant increase (p = 0.01) in lower limb functional strength (pre: 19.60 (SD = 2.19) vs post: 24.60(SD = 2.19)) with an effect size of d = 2.28 and a decrease in CRF (p = 0.245) (pre: 29.36 ± 24.42; post: 17.85 ± 14.23) with a trivial effect size (d < 0.5).

CONCLUSIONS

These preliminary findings indicate that a supervised once per week multimodal program that includes hypopressive exercises for postmenopausal cancer survivors increased lower limb functional strength without exacerbating their CRF. These findings support further randomized trials of hypopressive training programs on patients with cancer.

Effect of Perceptual Stress Reduction Control Intervention on the Level of Symptoms in Breast Cancer at Different Time Points

Background

To investigate the effect of perceptual stress reduction control intervention on the level of symptomatic groups at different time points in breast cancer.

Methods

A total of 124 breast cancer patients were divided into intervention group and control group, 62 cases in each group. Perioperative nursing and chemotherapy nursing were given to the control group, and the intervention group was given the interventional stress reduction control intervention. The level of symptom clusters of different time points were compared between the two groups.

Results

The incidence and severity of myelosuppression in the intervention group were slightly lower than those in the control group. The adverse reactions of bone marrow suppression at T3 were much lower than those in the control group, and the differences were significant (P=0.003, P=0.043). The control group had higher incidence and more severe symptoms of nausea, vomiting and diarrhea than the intervention group (P=0.002, P=0.042). The symptoms of breast pain and swelling at T1 in the intervention group were significantly lower than those in the control group (P=0.000, P=0.000). There was no significant difference in breast symptoms between the two groups at T2 and T3 (p>0.05). At the time of T2 and T3 of chemotherapy, the health promotion behavior scores of the intervention group were higher than the control group, and the difference was statistically significant (P_T2=0.000, P_T3=0.000).

Conclusion

Perceptual stress reduction control intervention can effectively relieve bone marrow suppression, digestive tract discomfort and breast symptoms, and promote health promotion behavior.

Psychosocial Issues Associated with Breast Cancer-Related Lymphedema: a Literature Review

PURPOSE OF REVIEW

Breast cancer-related lymphedema (BCRL) is a chronic disease affecting breast cancer survivors. The purpose of this article is to update the scientific literature regarding psychosocial issues associated with BCRL.

RECENT FINDINGS

Reports describe economic burdens, social support, sexuality, BCRL patient-education needs, and interventions to reduce BCRL symptoms and improve QOL among women with breast cancer. The psychosocial impact of BCRL may differ between younger and older women which has implications for age-related interventions to reduce the adverse psychosocial experiences of women with BCRL. We did not locate studies reporting the psychosocial impact of BCRL on male breast cancer survivors.

SUMMARY

More psychosocial-based interventions are needed that target the concerns of those with BCRL, including age-related needs, sexual concerns, body image, and social support. Future research is indicated to study the psychosocial impact of BCRL among men. Researchers may consider how pandemic-driven health care policies affect the psychosocial needs of those with BCRL.

Improvement of well-being in cancer patients by yoga training

Background: Cancer patients frequently suffer from a reduced physical activity. Non-pharmacological interventions, such as yoga, provide opportunities to deal with these symptoms. The aim of this study is to evaluate the effect of yoga on the well-being of cancer patients.Methods: Between 2015 and 2017, we analyzed the effects of yoga on the well-being of cancer patients. Fifty-one patients received yoga training specifically designed to address cancer-related problems. Before the start (SoS) and after the end (EoS) of training, the WHO-5 well-being index was used to evaluate patients’ perception.Results: WHO-5 scores significantly improved from 47.1±21.4 at SoS to 69.7±15.1 at EoS. Patients in the middle age group (EoS–SoS: 28.0±20.6) showed a significantly higher benefit (p<0.005) compared with age groups <40 years (EoS–SoS: 10.7±15.4) and >60 years (EoS–SoS: 16.0±12.1). Patients with low initial scores benefited most from yoga.Conclusion: Our study showed that yoga training under experienced supervision could serve as a beneficial complementary treatment in cancer patients. Best effects were observed in patients with highly reduced well-being and 40–60-year-old patients.

The Effect of Yoga on Arm Volume, Strength, and Range of Motion in Women at Risk for Breast Cancer-Related Lymphedema

OBJECTIVES

To assess the feasibility, safety, and initial estimates of efficacy of a yoga program in postoperative care for women at high risk for breast cancer-related lymphedema (BCRL).

DESIGN

Single-group pretest-post-test design.

SETTINGS/LOCATION

Patients were recruited from the University of California, San Francisco Carol Franc Buck Breast Care Center.

SUBJECTS

Twenty-one women were enrolled in the study. Women were >18 years of age, had undergone surgical treatment for breast cancer, and were at high risk for BCRL.

INTERVENTION

The women participated in an Ashtanga yoga intervention for 8 weeks. Sessions consisted of once/week instructor-led practice and once/week home practice. Particular attention was given to poses that emphasized upper body strength and flexibility, while avoiding significant time with the upper extremity (UE) in a dependent position.

OUTCOME MEASURES

UE volume was assessed through circumferential forearm measurement, which was converted to volume using the formula for a truncated cone. Range of motion (ROM) was assessed for the shoulders, elbows, and wrists, using a standard goniometer. UE strength was assessed for shoulder abduction, elbow flexion, wrist flexion, and grip using a dynamometer.

RESULTS

Twenty women completed the yoga intervention, with 17 returning for final assessment. Mean age was 52 (±9.1) years and body mass index was 24.8 (±5.1) kg/m². Postintervention, mean volume in the at-risk UE was slightly reduced (p = 0.397). ROM for shoulder flexion (p < 0.01) and external rotation (p < 0.05) significantly increased bilaterally. Shoulder abduction ROM significantly improved for the unaffected limb (p = 0.001). Following intervention, strength improved on the affected side for shoulder abduction and grip strength, and bilaterally for elbow flexion (p < 0.05 for all).

CONCLUSIONS

These preliminary findings suggest that yoga is feasible and safe for women who are at risk for BCRL and may result in small improvements in shoulder ROM and UE strength.
