Yoga effectively reduces fatigue and symptoms of depression in patients with different types of cancer

Impact of different exercise types on depression and anxiety in individuals with cancer: A systematic review and network meta-analysis of randomized controlled trials

OBJECTIVE

Various exercise modalities have been demonstrated to be effective in alleviating anxiety and depression among individuals with cancer. However, it remains unclear which specific exercise intervention is the optimal choice. This study aimed to systematically evaluate the impact of different exercise intervention types on anxiety and depression in individuals with cancer.

METHODS

Eligible randomized controlled trials were identified through searches of PubMed, Web of Science, and EBSCOHost, with the search period up to December 2024. Two researchers independently conducted the literature screening, data extraction, and assessment. Statistical analyses and visualizations were performed using Stata 15.0 software and RevMan5.4 software.

RESULTS

A total of 26 randomized controlled trials (involving 2118 individuals with cancer) examining three types of exercise interventions were included. Compared to usual care, mind-body exercise (SMD = -0.58, 95 % CI (-0.99, -0.17)), followed by resistance training (SMD = -0.52, 95 % CI (-1.12, 0.09)), and aerobic exercise (SMD = -0.51, 95 % CI (-0.89, -0.13)) significantly decreased depression levels among individuals with cancer. Additionally, resistance training (SMD = -0.66, 95 % CI (-1.59, 0.27)), followed by aerobic exercise (SMD = -0.59, 95 % CI (-1.08, -0.10)), and mind-body exercise (SMD = -0.48, 95 % CI (-0.96, 0.00)) significantly decreased anxiety levels among individuals with cancer compared to usual care.

CONCLUSION

The findings of this network meta-analysis suggest that mind-body exercise, resistance training, and aerobic exercise are all effective interventions for reducing anxiety and depression among individuals with cancer.

Use of Complementary and Integrative Health Approaches in Adults with Long COVID in the US, a Nationally Representative Survey

Background: Long COVID is a serious, complex condition that has affected the lives of millions of people globally. Complementary and integrative health (CIH) approaches offer a wide range of potential therapies for the management of long COVID symptoms. However, there is limited information available about the utilization of CIH among long COVID patients. Methods: Nationally representative cross-sectional data from the United States 2022 National Health Interview Survey (NHIS, response rate 47.7%, n = 27,651) were used to investigate prevalence and predictors of CIH use in the past 12 months among individuals who experienced long COVID. The 12-month prevalence of CIH use was descriptively analyzed for those with long COVID versus those without using chi-squared tests or unpaired t-tests. Independent predictors of CIH use among individuals with long COVID were analyzed using a stepwise multiple logistic regression analysis. Results: A weighted total of 17,610,801 US adults (19.7%) who had a confirmed case of coronavirus disease 2019 (COVID-19) developed long COVID symptoms. A slightly greater proportion of individuals with long COVID (44.4%) than those without (40.9%) used CIH approaches in the past 12 months. The most used approaches were meditation, yoga, and massage therapy. CIH use by those with long COVID was significantly associated with younger age, female sex, higher education level, having health insurance coverage, higher household income level, receiving three or more COVID-19 vaccination doses, ever having asthma, and ever having an anxiety or depression diagnosis. Conclusions: Long COVID represents a major challenge for patients, health care providers, health care systems, economies, and global public health. CIH approaches may play an important role in symptom management for some patients, and additional research is needed to identify which modalities are most effective. Patients and health care providers may benefit from better information about the available options for treatment.

The effectiveness of different non-pharmacological therapies on cancer-related fatigue in cancer patients:A network meta-analysis

BACKGROUND

Cancer-related fatigue is the most common symptom of subjective and persistent nature in cancer patients, which almost runs through the whole process of disease and treatment and rehabilitation, seriously affects the effect of anti-tumor treatment and reduces the quality of life of patients. Non-pharmacological management is one of the key links to relieve cancer-related fatigue, however, there are many types of non-pharmacological management and the related guidelines do not recommend the optimal nursing program for cancer-related fatigue. In our study, Network Meta-analysis was used to compare the effectiveness of different non-pharmacological therapies in Cancer-related fatigue to make their treatment and care more clinically valuable.

METHODS

Randomized controlled trials about non-pharmacological therapies for cancer-related fatigue were searched in Chinese and English databases including China National Knowledge Infrastructure, Wanfang Data Knowledge Service Platform, Chinese Scientific Journal database, Chinese Biomedical Database, Google Scholar, Pubmed, Web of science, Cochrane Library, Sci-Hub, ScienceDirect, and other relevant medical websites including Medlive and DingXiangYuan. The search time was from the establishment of the database to December 2023. The quality of the included Randomized controlled trials was evaluated by two trained researchers using the Cochrane Risk of Bias Assessment Tool, and data were independently extracted from the included literature and analyzed by reticulated Meta-analysis using Stata 18.0 statistical software.

RESULTS

A total of 49 studies with 24 non-drug management methods, and 3887 patients were included. The results of network meta-analysis showed that the use of massage therapy to improve cancer-related fatigue had a more significant advantage over conventional nursing measures and other non-pharmacological therapies in cancer patients, followed by infrared laser moxibustion and ginger-isolated moxibustion with traditional Chinese medicine characteristics, while the worst effect was strengthening excise.

CONCLUSIONS

The existing evidence shows that massage therapy has the best effect in the intervention of cancer-related fatigue. However, due to the diversity of non-pharmacological therapies and the small number of studies included in each therapy, the coverage of this study is insufficient, and more large-sample, multi-center and high-quality randomized controlled trials are needed for further verification in the future.

The Role of Spirituality and Religion in Improving Quality of Life and Coping Mechanisms in Cancer Patients

BACKGROUND/OBJECTIVES

This systematic review aimed to comprehensively evaluate the role of spirituality and religion in the journey of patients with cancer and assess their impact on various aspects of well-being and coping mechanisms.

METHODS

Systematic searches were conducted in PubMed, Scopus, and Google Scholar following the PRISMA guidelines. This study focused on the period from 2014 to 2024, the time chosen for the emerging integration of spirituality and religion in cancer treatment. Inclusion criteria targeted studies exploring the impact of spirituality and religion on cancer patients' quality of life, coping, and treatment outcomes.

RESULTS

A comprehensive search initially yielded 2591 papers, of which 1544 were excluded as duplicates, and 113 were further excluded based on the inclusion criteria. Ultimately, 53 papers were selected for review, including 8 prospective cohort, 17 cross-sectional, 16 observational descriptive, and 12 RCT studies. Encompassing 13,590 patients with various cancer types, including breast, gastrointestinal, prostate, brain, and others, the review highlighted spirituality and religion's significant role in improving cancer patients' well-being. Across different cancers, greater spiritual well-being and religious coping were consistently associated with an improved quality of life, reduced distress, enhanced coping, and better treatment outcomes. Interventions such as mindfulness therapy, yoga, and religious coping strategies positively impact patients' spiritual and emotional well-being.

CONCLUSIONS

This review highlights the vital role of spirituality and religion in cancer care. Integrating these aspects into patient plans offers comfort and support throughout treatment. Healthcare providers should prioritize spiritual support to enhance patient well-being and optimize outcomes.

Study protocol for a multicentre randomised controlled trial evaluating the efficacy of an online yoga intervention in high-grade glioma patients and their caregivers: the YINOTA-O-trial

INTRODUCTION

High-grade glioma patients and their caregivers often suffer from distress and a lower quality of life. Results from studies with patients with mixed cancer entities suggest that yoga can be an effective support. However, it is unclear whether this also applies to high-grade glioma patients and their caregivers. This study aims to investigate the effects of mindfulness-based online yoga for patients and their caregivers on emotional distress, quality of life and stress-associated physiological parameters compared with a waiting control group (WCG).

METHODS & ANALYSIS

The study is designed as a multicentre randomised controlled trial. Adult glioma patients (central nervous system WHO grades 3 and 4) and their caregivers will be recruited. Examined yoga instructors deliver the intervention (1 hour per week) in a synchronous format over 8 weeks via video conferencing. The WCG will receive standard care during the 8-week waiting period. Data will be collected before and after the end of the intervention and another 3 months later using questionnaires as well as blood serum and hair samples to evaluate biochemical stress parameters. Primary outcome is self-reported generalised anxiety and secondary outcomes are self-reported fear of progression, depression and quality of life as well as brain-derived neurotrophic factor (BDNF), dehydroepiandrosterone (DHEA)/dehydroepiandrosterone sulfate (DHEAS), ferritin and hair cortisol. We hypothesise better outcomes in the intervention group compared with the WCG at all measurement points. 70 patients and 70 caregivers will be recruited consecutively. Primary endpoints are significant effect detections in the Generalised Anxiety Disorder scale-7 of patients and caregivers at the end of the intervention. Analyses of covariance will be performed to analyse the treatment effects.

ETHICS AND DISSEMINATION

The Ethics Committee of the University of Würzburg approved the YINOTA-O (Yoga-Intervention bei Neuroonkologischen Tumorpatienten und deren Angehörigen - Online) study on 26 October 2021 (No.185/18-me). Results will be presented at conferences and published in peer-reviewed journals.

Correlates and patterns of using complementary health approaches among individuals with recent and longer-term cancer diagnoses: a US national cross-sectional study

PURPOSE

To (1) describe and compare the prevalence of using of complementary health approaches, focusing on mind and body practices, and reasons for use among cancer survivors, and (2) examine characteristics associated with use among those with a recent and non-recent diagnosis of cancer compared to those without a previous cancer diagnosis.

METHODS

Using data from the 2022 US National Health Interview Survey, prevalence estimates were derived for using any complementary health approach, by category (manipulative body-based [chiropractor, acupuncture, massage], creative [music therapy, art therapy], and mind-body [meditation, guided imagery, yoga]), and reasons for use. Regression models identified correlates of use among all participants and within cancer diagnosis subgroups.

RESULTS

Among 26,523 adult participants, overall prevalence of using any complementary approach was similar amongst individuals with recent cancer (40.17%), non-recent cancer (37.75%), and no cancer diagnosis (37.93%). However, odds of use were higher amongst recent (OR = 1.37) and relatively long term (OR = 1.14) cancer survivors compared to those without a history of cancer in adjusted models (both p < 0.05). In cancer survivors, mind-body approaches were mostly used for general health purposes, whereas manipulative approaches were used for general health and pain management. Female sex, younger age, higher education and income were among the prominent variables associated with using complementary approaches.

CONCLUSION

We present an important snapshot of the landscape of using complementary approaches, specifically mind and body practices, in adult cancer survivors in the US. Inequalities in access to these therapies may exist, as use remains highest amongst those with higher socioeconomic conditions.

IMPLICATIONS FOR CANCER SURVIVORS

Given the prevalence and potential benefits of complementary approaches among cancer survivors, there is a need to better understand their effectiveness, optimal use, and integration into cancer care. Further research is needed to understand and address access barriers that might exist amongst some cancer survivors.

Research progress on the psychological burden and intervention measures in cancer patients

In the past 40 years, the gradually increasing incidence and mortality rates of malignant tumors have severely impacted the quality of life of patients, bringing significant physical and psychological burdens and becoming an increasingly serious social issue. With the development of medical standards, new methods for cancer detection and treatment have been continuously proposed. Although it has been proven that cancer is related to increased psychological burden and suicidal behaviors in patients, current research on the psychological burden caused by cancer is insufficient. Clinicians often overlook the psychological health issues of patients while treating their physical diseases. Considering the high incidence of cancer, this review will outline the psychological burdens of cancer patients worldwide in recent years and its high-risk factors. Moreover, this review will summarize the common methods for evaluating psychological burdens, present current predictive models and treatment methods for the psychological burden of cancer patients, aiming to provide a research basis and future direction for the timely and accurate assessment of the psychological burden in cancer patients.

Chairside Yoga Therapy Alleviates Symptoms in Patients Concurrently Receiving Outpatient Cancer Infusions: A Promising Feasibility Study

Purpose: To evaluate effectiveness of chairside yoga therapy on perceptions of fatigue, pain, nausea, anxiety, and distress among oncology patients concurrently receiving outpatient cancer infusion therapy. Design: This prospective pilot study used pre-/post-survey design in convenience sample of cancer patients in outpatient setting. Methods: Researchers developed and administered the Outpatient Cancer Symptom Assessment Scale (OCSAS) comprised of cancer- or treatment-related symptoms commonly reported in the oncology population (nausea, pain, fatigue, anxiety, and distress). Following IRB approval, symptoms were rated using Likert scale of 0 (not present) to 10 (severe) before and after chairside yoga therapy delivered concurrently with outpatient infusions. Qualitative data was collected related to patients' overall infusion experience. Findings: Participants (n = 82) reported positive patient experiences and statistically less pain (p < 0.001), fatigue (p < 0.001), anxiety (p < 0.001), and distress (p < 0.001) following the yoga intervention compared to baseline. Nausea was not significantly impacted by the yoga intervention. Conclusions: Yoga therapy received concurrently during outpatient cancer infusion is consistent with a holistic and integrative approach to care for the oncology population. Yoga therapy offers promise for reducing symptoms which negatively impact quality of life, including pain, fatigue, anxiety, and distress. Qualitative data suggests patients' overall infusion experience was enhanced with yoga therapy.

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.

Yoga Therapy as an Intervention to Improve Patient-Reported Outcomes Among Adults After Treatment for Cancer: Preliminary Findings From a Trial Using Single-Subject Experimental Design

BACKGROUND

Cancer is a chronic condition associated with a substantial symptom burden, which can impair recovery after treatment. Investigating interventions with potential to improve self-reported disease and/or treatment effects-known as patient-reported outcomes (PROs)-is paramount to inform cancer care. The objective of this study was to evaluate the effects of a yoga therapy (YT) intervention on key PROs (ie, cancer-related fatigue, anxiety, cognitive function, depression, stress, quality of life [QoL]) among adults after treatment for cancer.

METHODS

Data from 20 adults (Mage = 55.74 years, 85% female; Mtime since diagnosis = 2.83 years) who had completed treatment for cancer were analyzed for this study. In this single-subject exploratory experimental study, the YT intervention comprised a 1:1 YT session (ie, 1 participant with 1 yoga therapist) followed by 6 weekly small (ie, 2-3 participants) group YT sessions. Group sessions were facilitated by the same yoga therapist who delivered participants' 1:1 session to ensure an in-depth personalized approach. PROs were assessed before (ie, pre-intervention) and after the 1:1 YT session (ie, during the intervention), as well as after the last group YT session (ie, post-intervention). Hierarchical linear modeling was used to analyze the data.

RESULTS

Participants showed improvements in cancer-related fatigue, state anxiety, trait anxiety, perceived cognitive impairments, impacts of perceived cognitive impairments on QoL, and 1 dimension of QoL (ie, functional wellbeing) over time. Notably, cancer-related fatigue and state anxiety increased immediately after the 1:1 session, but showed greater improvements over time afterward (ie, during the intervention phase). No changes were observed for the remaining PROs.

CONCLUSION

Although results require confirmation in future trials, this study highlights the importance of continuing to investigate YT as an intervention to enhance important PROs (ie, cancer-related fatigue and state anxiety) after treatment for cancer. More research is needed to identify additional beneficial effects and factors that influence participants' responses to 1:1 and group YT (ie, moderators and mediators).

Factors affecting physical and mental fatigue in adults from South Korea: A cross-sectional study

In modern society, demanding and stressful events contribute to increased fatigue in adults. Moreover, fatigue is the most prevalent symptom of long coronavirus disease 2019. Fatigue is a subjective feeling of tiredness that can be attributed to various causes. This cross-sectional study investigated factors affecting physical and mental fatigue in adults living in South Korea. Self-reported data were collected through an online survey conducted between July 11 and July 17, 2021. The final sample comprised 362 participants, excluding those with uncertain responses. The collected data were analyzed using IBM SPSS version 27.0. General characteristics and variables of the participants were examined through descriptive statistical analysis. Differences in fatigue level according to the general characteristics of the participants were analyzed using t tests and one-way analysis of variance. The correlation between variables was analyzed using Pearson correlation coefficients. To investigate factors affecting fatigue, stepwise multiple regression analysis was conducted. The overall level of fatigue according to participants' general characteristics differed significantly based on alcohol use, economic status, number of chronic diseases, stress, depression, and sleep problems. Factors affecting physical fatigue were depression, sleep problems, General Health Questionnaire (GHQ-12) scores, and number of chronic diseases. The factors affecting mental fatigue were depression, GHQ-12 score, and alcohol use. The variables that had the most significant impact on overall fatigue were alcohol consumption, the number of chronic illnesses, depression, and GHQ-12, in that order. This emphasizes the importance of lifestyle improvement and dietary management in adults for preventing chronic diseases and managing mental health. The results of this study should be considered when planning health services to provide fatigue interventions for Korean adults.

Changes of Symptoms of Anxiety, Depression, and Fatigue in Cancer Patients 3 Months after a Video-Based Intervention

During the COVID-19 pandemic, social distancing restricted psycho-oncological care. Therefore, this secondary analysis examines the changes in anxiety, fear of progression, fatigue, and depression in cancer patients after a video-based eHealth intervention. We used a prospective observational design with 155 cancer patients with mixed tumor entities. Data were assessed before and after the intervention and at a three-month follow-up using self-reported questionnaires (GAD-7, FOP-Q-SF, PHQ-8, and EORTC QLQ-FA12). The eight videos included psychoeducation, Acceptance and Commitment Therapy elements, and yoga and qigong exercises. The results showed that three months after finishing the video-based intervention, participants showed significantly reduced fear of progression (d = -0.23), depression (d = -0.27), and fatigue (d = -0.24) compared to the baseline. However, there was no change in anxiety (d = -0.09). Findings indicated marginal improvements in mental distress when using video-based intervention for cancer patients for up to three months, but long-term effectiveness must be confirmed using a controlled design.

Integrative Oncology Care of Symptoms of Anxiety and Depression in Adults With Cancer: Society for Integrative Oncology-ASCO Guideline

PURPOSE

To provide evidence-based recommendations to health care providers on integrative approaches to managing anxiety and depression symptoms in adults living with cancer.

METHODS

The Society for Integrative Oncology and ASCO convened an expert panel of integrative oncology, medical oncology, radiation oncology, surgical oncology, palliative oncology, social sciences, mind-body medicine, nursing, methodology, and patient advocacy representatives. The literature search included systematic reviews, meta-analyses, and randomized controlled trials published from 1990 through 2023. Outcomes of interest included anxiety or depression symptoms as measured by validated psychometric tools, and adverse events. Expert panel members used this evidence and informal consensus with the Guidelines into Decision Support methodology to develop evidence-based guideline recommendations.

RESULTS

The literature search identified 110 relevant studies (30 systematic reviews and 80 randomized controlled trials) to inform the evidence base for this guideline.

RECOMMENDATIONS

Recommendations were made for mindfulness-based interventions (MBIs), yoga, relaxation, music therapy, reflexology, and aromatherapy (using inhalation) for treating symptoms of anxiety during active treatment; and MBIs, yoga, acupuncture, tai chi and/or qigong, and reflexology for treating anxiety symptoms after cancer treatment. For depression symptoms, MBIs, yoga, music therapy, relaxation, and reflexology were recommended during treatment, and MBIs, yoga, and tai chi and/or qigong were recommended post-treatment.

DISCUSSION

Issues of patient-health care provider communication, health disparities, comorbid medical conditions, cost implications, guideline implementation, provider training and credentialing, and quality assurance of natural health products are discussed. While several approaches such as MBIs and yoga appear effective, limitations of the evidence base including assessment of risk of bias, nonstandardization of therapies, lack of diversity in study samples, and lack of active control conditions as well as future research directions are discussed.Additional information is available at www.asco.org/survivorship-guidelines.

Effects of exercise interventions on cancer-related fatigue and quality of life among cancer patients: a meta-analysis

PURPOSE

In this study, exercise interventions were evaluated for their effects on cancer-related fatigue (CRF) and quality of life (QoL) among cancer patients.

DESIGN

A meta-analysis was performed.

METHODS

We systematically searched the PubMed/Medline, Web of Science, Embase, Cochrane Central Register of Controlled Trials (CENTRAL), PsycINFO, and CINAHL databases, and gray literature sources including the Virginia Henderson International Nursing Library and Google Scholar. This study only included randomized controlled trials (RCTs) examining how exercise interventions affect CRF and QoL among cancer patients. Based on the Cochrane Risk-of-Bias Assessment Tool, version 2 (RoB 2) and the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach, the methodological quality of the included studies was evaluated. In addition, standardized mean differences (SMDs) and 95% confidence intervals (CIs) were applied to assess the intervention effect with respect to CRF and QoL. Data analysis was performed using Review Manager (version 5.4).

RESULTS

There were a total of 1573 participants in the 28 included articles. According to the meta-analysis, CRF (SMD = -0.35, 95% CI: -0.63 to -0.07, p = 0.01) and QoL (SMD = 0.36, 95% CI: 0.20 to 0.53, p < 0.01) were positively affected by exercise interventions. Subgroup analyses revealed considerable improvements in CRF (SMD = -0.54, 95% CI: -1.00 to -0.09, p = 0.02) and QoL (SMD = 0.38, 95% CI: 0.16 to 0.59, p < 0.01) from aerobic exercise. An intervention duration less than 12 weeks had a better effect on CRF (SMD = -0.80, 95% CI: -1.43 to -0.17, p = 0.01) and QoL (SMD = 0.53, 95% CI: 0.21 to 0.85, p < 0.01), and three times per week was the most effective frequency in improving QoL (SMD = 0.69, 95% CI: 0.28 to 1.11, p < 0.01). Exercise intervention was more successful in improving CRF (SMD = -0.66, 95% CI: -1.10 to -0.21, p < 0.01) and QoL (SMD=-0.50, 95% CI: 0.23 to 0.78, p < 0.01) in female cancer patients. Sensitivity analyses showed that the pooled outcomes were reliable and stable.

CONCLUSION

Exercise interventions are a workable approach to improve CRF and QoL among cancer patients. An aerobic exercise intervention of less than 12 weeks might be most effective in improving CRF and QoL, and three times per week might be the most appropriate frequency. Exercise might have a more positive effect on improving CRF and QoL in female cancer patients. Additionally, a larger number of high-quality RCTs should be conducted to further confirm the efficacy of exercise interventions on CRF and QoL among cancer patients.

Effects of Brain Wave Vibration Training on the Pain and Fatigue Disturbance Symptom Cluster in Persons with Cancer: A Randomized Controlled Trial

Pain and fatigue disturbance constitute the most common symptom cluster in persons with cancer, causing physical and psychological problems associated with a decreased quality of life. This study investigated the effects of brain wave vibration (BWV) training on the pain and fatigue disturbance symptom cluster in persons with cancer. A total of 43 participants were voluntarily recruited and randomly assigned to the experimental group (BWV with therapeutic massage, n = 25) or the control group (conventional physical therapy with spontaneous physical activity, n = 18) (Randomized controlled trial registration number: KCT0005843). BWV with therapeutic massage was performed for a total of 24 sessions (70 min/day, 2 days/week for 12 weeks). The Breakthrough Pain Assessment Tool and Brief Fatigue Inventory were used to evaluate cancer-related pain (CRP) and cancer-related fatigue (CRF), respectively. Regarding CRP variables, the experimental group demonstrated significant improvements in the worst and typical episodes of breakthrough pain, pain distress, and interference with living a normal life compared to the control group. In CRF, there was no significant difference between the groups, although BWV training with therapeutic massage resulted in a significant difference between before and after the intervention. Therefore, our study suggests that BWV training with therapeutic massage is beneficial for improving CRP and CRF in cancer survivors.

Effects of a Video Sequence Based Intervention on Anxiety, Fatigue and Depression in Cancer Patients: Results of a Randomized Controlled Trial

BACKGROUND

Cancer patients often suffer from psychological symptoms and need psychological support. Especially during the COVID-19 pandemic, eHealth interventions might be helpful to overcome the obstacles of the pandemic. This study evaluates the effectiveness of a video sequence-based eHealth intervention on anxiety, fatigue, and depression in cancer patients.

METHODS

Patients (N = 157) with different tumor entities were randomly assigned to the video intervention group (IG) and the waiting control group (CG). Patients in the IG received a video intervention comprising 8 video sequences over 4 weeks. The videos included psychoeducation on distress and psychological symptoms, Acceptance and Commitment Therapy elements, and Yoga and Qigong exercises. Patients' anxiety and fear of progression (primary outcomes) and secondary outcomes were assessed before randomization (T1) and after the end of the intervention for IG or the waiting period for CG (T2) using self-reported questionnaires (GAD-7, PA-F-KF, EORTC QLQ-FA12, PHQ-8).

RESULTS

Patients of the IG showed no significant improvement in anxiety (GAD-7; P = .75), fear of progression (FoP-Q-SF; P = .29), fatigue (EORTC QLQ-FA12; P = .72), and depression (PHQ-8; P = .95) compared to patients in the waiting CG. However, symptoms of anxiety, fatigue, and depression decreased in both groups. Exploratory subgroup analysis regarding sex, therapy status, therapy goal, and tumor entity showed no effects. Overall, the intervention had a high level of acceptance.

CONCLUSIONS

The video intervention was ineffective in reducing the psychological burden compared to a waiting CG. The findings support prior observations of the value of therapeutic guidance and promoting self-management for improving patients' psychological burdens. Further studies are required to evaluate the effectiveness of psycho-oncological eHealth delivered through video sequences.

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.

Effect of Yoga and Mediational Influence of Fatigue on Walking, Physical Activity, and Quality of Life Among Cancer Survivors

BACKGROUND

Cancer-related fatigue (CRF) negatively affects survivors' walking, engagement in physical activity (PA), and quality of life (QoL). Yoga is an effective therapy for treating CRF; however, evidence from large clinical trials regarding how reducing CRF through yoga influences CRF's interference with survivors' walking, engagement in PA, and QoL is not available. We examined the effects of yoga and the mediational influence of CRF on CRF's interference with walking, PA, and QoL among cancer survivors in a multicenter phase III randomized controlled trial.

PATIENTS AND METHODS

Cancer survivors (n=410) with insomnia 2 to 24 months posttreatment were randomized to a 4-week yoga intervention-Yoga for Cancer Survivors (YOCAS)-or standard care. A symptom inventory was used to assess how much CRF interfered with survivors' walking, PA, and QoL. The Multidimensional Fatigue Symptom Inventory-Short Form was used to assess CRF. Two-tailed t tests and analyses of covariance were used to examine within-group and between-group differences. Path analysis was used to evaluate mediational relationships between CRF and changes in CRF's interference with walking, PA, and QoL among survivors.

RESULTS

Compared with standard care controls, YOCAS participants reported significant improvements in CRF's interference with walking, PA, and QoL at postintervention (all effect size = -0.33; all P≤.05). Improvements in CRF resulting from yoga accounted for significant proportions of the improvements in walking (44%), PA (53%), and QoL (45%; all P≤.05).

CONCLUSIONS

A significant proportion (44%-53%) of the YOCAS effect on CRF's interference with walking, PA, and QoL was due to improvements in CRF among cancer survivors. Yoga should be introduced and included as a treatment option for survivors experiencing fatigue. By reducing fatigue, survivors further improve their walking, engagement in PA, and QoL.

Long-Term Yogic Intervention Improves Symptomatic Scale and Quality of Life by Reducing Inflammatory Cytokines and Oxidative Stress in Breast Cancer Patients Undergoing Chemotherapy and/or Radiotherapy: A Randomized Control Study

INTRODUCTION

Inflammation has been associated with tumor proliferation and metastasis in breast cancer. Yoga is an ancient therapy that helps in reducing inflammation and improves the patient's quality of life (QoL) and fatigue. In the current study, we investigated the effects of long-term yogic intervention at different time points on the level of inflammatory cytokines and oxidative stress, along with the symptomatic scale and QoL in stage II/III breast cancer patients.

METHODS

Ninety-six stage II/III breast cancer patients receiving chemotherapy and/or radiotherapy were enrolled and divided into two groups, non-yoga (Group I) and yoga (Group II). Participants in Group II practiced yoga five days per week for 48 weeks. The European Organisation for Research and Treatment of Cancer quality of life questionnaire (EORTC-QLQ30) was used to measure the QoL and symptomatic scale. Serum levels of pro-inflammatory cytokines, tumor necrosis factor-alpha (TNF-α), interferon-γ (IFN-γ) and granulocyte macrophage colony-stimulating factor (GM-CSF), and oxidative stress markers, superoxide dismutase (SOD), catalase (CAT), malondialdehyde (MDA), and nitric oxide (NO) were measured at baseline, 16, 32, and 48 weeks in both groups.

RESULTS

Yoga significantly (p<0.05) reduced the level of IFN-γ, TNF-α, and MDA and improved QoL (p<0.001) and symptomatic scale (p<0.05) in Group II patients compared to Group I. NO was upregulated in Group I whereas in Group II, it was neither decreased nor increased.

CONCLUSION

These findings suggest that yoga may reduce levels of inflammatory cytokines and improve QoL and symptomatic scale in breast cancer patients receiving chemotherapy and/or radiotherapy. Yoga can be an important additional therapy during cancer treatments to cope with treatment side effects including fatigue, depression, and immunological profile, which directly affects the patient's quality of life.

Long-term yogic intervention decreases serum interleukins IL-10 and IL-1β and improves cancer-related fatigue and functional scale during radiotherapy/chemotherapy in breast cancer patients: a randomized control study

PURPOSE

Yoga improved fatigue and immunological profile in cancer survivors and has been a promising alternative therapy. Breast cancer treatments are rapidly improving, along with their side effects. This article investigated the effect of the yogic intervention at a different time interval during radiotherapy/chemotherapy on the pro- and anti-inflammatory interleukins along with the cancer-related fatigue and functional scale among patients with stage II/III breast cancer.

METHODS

A total of 96 stage II/III breast cancer patients were enrolled in this study and randomly divided into two different groups. Group I (non-Yoga) received chemotherapy and/or radiotherapy and group II (Yoga) received an additional yogic intervention. Both groups were followed up for a period of 48 weeks and blood was collected at the time of enrollment, 16, 32, and 48 weeks, and serum was isolated to measure the pro- and anti-inflammatory interleukins, fatigue, and functional scale questionnaire obtained at each time point.

RESULTS

Breast cancer patients in group II showed a significant improvement (p < 0.05) in the functional scale and fatigue from baseline to 48 weeks compared to group I. The yogic intervention significantly decreased (p < 0.05) the level of pro-inflammatory interleukin IL-1β and pleiotropic interleukin IL-10 in group II compared to group I.

CONCLUSION

These finding suggested that improved fatigue and functional scale is associated with a lower level of IL-1β and IL-10. Yoga may be an important additional therapy along with the cancer treatment to help the patients with cancer-related fatigue and improve their overall immunological profile.

Digitally distributed Yoga Intervention in Breast Cancer Rehabilitation (DigiYoga CaRe): protocol for a randomised controlled trial

INTRODUCTION

Breast cancer is the most prevalent cancer among women. The treatment is extensive; in addition to surgery, various combinations of radiation therapy, chemotherapy and antibody and endocrine treatment can be applied. Cancer-related fatigue (CRF) is high in patients with breast cancer, peaking during chemotherapy, but may persist for several years. Physical activity has proven to be effective in reducing CRF in breast cancer rehabilitation, but many patients tend to be less active after the diagnosis. Yoga has a previously demonstrated effect on energy levels and digitally distributed yoga intervention can potentially increase accessibility in pandemic times and facilitate participation for patients susceptible to infection and those living far from organised rehabilitation opportunities. The purpose of this study, Digital Yoga Intervention in Cancer Rehabilitation (DigiYoga CaRe) is to investigate whether a 12-week digitally distributed yoga intervention can reduce CRF and stress, improve health-related quality of life (HRQL) and affect pro-inflammatory and metabolic markers in patients with breast cancer.

METHODS AND ANALYSIS

This multicentre study will adopt a randomised controlled design including 240 persons after their breast cancer surgery. They will be randomised to a 12-week digitally distributed yoga intervention or to a control group. The intervention group practice yoga two times a week, one yoga class live-streamed to the patient's computer or mobile device and one prerecorded video class for self-training. The controls receive standardised care, gift cards for flowers and access to yoga video links after the data collection has ended. The primary analysis will be performed following the principle of intention to treat. Data will be collected by questionnaires, blood samples, accelerometers and interviews.

ETHICS AND DISSEMINATION

The DigiYoga CaRe study was approved by the Regional Ethical Review Board in Lund. The final results of this study will be disseminated to conference, patient and public involvements and peer-reviewed publications.

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.

Integrative oncology: Addressing the global challenges of cancer prevention and treatment

The increase in cancer incidence and mortality is challenging current cancer care delivery globally, disproportionally affecting low- and middle-income countries (LMICs) when it comes to receiving evidence-based cancer prevention, treatment, and palliative and survivorship care. Patients in LMICs often rely on traditional, complementary, and integrative medicine (TCIM) that is more familiar, less costly, and widely available. However, spheres of influence and tensions between conventional medicine and TCIM can further disrupt efforts in evidence-based cancer care. Integrative oncology provides a framework to research and integrate safe, effective TCIM alongside conventional cancer treatment and can help bridge health care gaps in delivering evidence-informed, patient-centered care. This growing field uses lifestyle modifications, mind and body therapies (eg, acupuncture, massage, meditation, and yoga), and natural products to improve symptom management and quality of life among patients with cancer. On the basis of this review of the global challenges of cancer control and the current status of integrative oncology, the authors recommend: 1) educating and integrating TCIM providers into the cancer control workforce to promote risk reduction and culturally salient healthy life styles; 2) developing and testing TCIM interventions to address cancer symptoms or treatment-related adverse effects (eg, pain, insomnia, fatigue); and 3) disseminating and implementing evidence-based TCIM interventions as part of comprehensive palliative and survivorship care so patients from all cultures can live with or beyond cancer with respect, dignity, and vitality. With conventional medicine and TCIM united under a cohesive framework, integrative oncology may provide citizens of the world with access to safe, effective, evidence-informed, and culturally sensitive cancer care.

Effectiveness of exercise training on cancer-related fatigue in colorectal cancer survivors: a systematic review and meta-analysis of randomized controlled trials

PURPOSE

To investigate the effects of exercise training on cancer-related fatigue (CRF) in colorectal cancer survivors.

METHODS

Randomized controlled trials published between 1 January 2010 and 19 October 2020, selected through online search conducted in PubMed, Scopus, Web of Science, SPORTDiscus and PEDro databases, were included. Eligible trials compared the effect of exercise training interventions, versus non-exercise controls on CRF, in colorectal cancer survivors, during or after treatment. The methodological quality of individual studies was analysed using the Physiotherapy Evidence Database (PEDro) scale. Standardized mean differences (SMD) that were pooled using random-effects models were included as the effect size. In addition, 95% prediction intervals (PI) were calculated.

RESULTS

Six trials involving 330 colorectal cancer patients met the inclusion criteria and presented reasonable to good methodological quality. An overall small-to-moderate effect of exercise training on CRF was found (SMD =  - 0.29: 95% CI: [- 0.53; - 0.06]; p = 0.01; PI: [- 0.63; 0.04]; low-quality evidence). Subgroup analysis revealed moderate effects of exercise interventions performed during chemotherapy (SMD =  - 0.63; 95% CI: [- 1.06; - 0.21]; p = 0.003) and small, non-significant effects, when exercise training was performed after cancer treatment (SMD =  - 0.14; 95% CI: [- 0.43; 0.14]; p = 0.32). Steady improvements were achieved when a combination of aerobic plus resistance exercise was used, in interventions lasting 12 to 24 weeks.

CONCLUSION

Exercise training could be regarded as a supportive therapy for the clinical management of CRF in colorectal cancer patients undergoing chemotherapy, but further studies are necessary to clarify the effects of exercise interventions on CRF after cancer treatment.

Psychological intervention to treat distress: An emerging frontier in cancer prevention and therapy

Psychological distress, such as chronic depression and anxiety, is a topical problem. In the context of cancer patients, prevalence rates of psychological distress are four-times higher than in the general population and often confer worse outcomes. In addition to evidence from epidemiological studies confirming the links between psychological distress and cancer progression, a growing body of cellular and molecular studies have also revealed the complex signaling networks which are modulated by psychological distress-derived chronic stress during cancer progression. In this review, aiming to uncover the intertwined networks of chronic stress-driven oncogenesis and progression, we summarize physiological stress response pathways, like the HPA, SNS, and MGB axes, that modulate the release of stress hormones with potential carcinogenic properties. Furthermore, we discuss in detail the mechanisms behind these chronic stimulations contributing to the initiation and progression of cancer through direct regulation of cancer hallmarks-related signaling or indirect promotion of cancer risk factors (including obesity, disordered circadian rhythms, and premature senescence), suggesting a novel research direction into cancer prevention and therapy on the basis of psychological interventions.

Yoga therapy to reduce fatigue in cancer: effects of reminder e-mails and long-term efficacy

Objective

To examine the efficacy of reminder e-mails to continue yoga therapy on practice frequency and fatigue in cancer patients and long-term effects of yoga on fatigue, depression, and quality of life.

Methodology

One hundred two cancer patients who completed an 8-week yoga therapy were randomly allocated to two groups: reminder (N = 51) vs. no-reminder group (N = 51). After completing yoga therapy, the reminder group received weekly e-mails for 24 weeks, which reminded them of practicing yoga, whereas the no-reminder group did not. Primary outcomes were fatigue and practice frequency, and long-term outcomes were fatigue, depression, and quality of life. Data were assessed using questionnaires after yoga therapy (T1) and 6 months after completing yoga therapy (T2).

Result

A significantly stronger reduction of general (p = 0.038, d = 0.42) and emotional fatigue (p = 0.004, d = 0.59) and a higher increase of practice frequency (p = 0.015, d = 0.52) between T1 and T2 were found for the reminder group compared to the no-reminder group. In the mediation model, practice frequency as a mediator partially explained the changes in emotional fatigue (indirect effect B =  − 0.10). Long-term effects of yoga therapy regarding fatigue, depression, and quality of life were found (F > 7.46, p < 0.001, d > 0.54).

Conclusion

Weekly reminder e-mails after yoga therapy can positively affect general and emotional fatigue and help cancer patients with fatigue establish a regular yoga practice at home. However, higher practice frequency did not lead to higher physical or cognitive fatigue improvement, suggesting other factors that mediate efficacy on physical or cognitive fatigue, such as mindfulness or side effects of therapy.

Yoga for depression and anxiety symptoms in people with cancer: A systematic review and meta-analysis

OBJECTIVE

Cancer and its treatment can lead to a variety of physical and emotional concerns impacting on those affected, including subclinical or clinical depression and anxiety, which in turn have a significant impact on wellbeing, quality of life and survival. The aim of this review was to evaluate the effect of yoga-based interventions on self-reported depression and anxiety symptoms in people with cancer in randomized controlled trials.

METHOD

Six databases were searched to identify relevant studies. Systematic review procedures were followed including a quality assessment. Meta-analysis of suitable studies was conducted.

RESULTS

26 studies from our search criteria were eligible for inclusion for depressive and 16 for anxiety symptoms. Meta-analyses revealed evidence for significant medium effects of yoga on depression symptoms (N = 1,486, g = -0.419, 95% confidence interval [CI] = -0.558 to -0.281, p < 0.001) and anxiety (N = 977, g = -0.347, 95% CI = -0.473 to -0.221, p < 0.001) compared to controls. Subgroup analyses for depressive symptoms revealed significant effects for all analyses performed (type of cancer, type of control, treatment status, duration of intervention or frequency of yoga sessions), with effect sizes being comparable between subgroups. Similar findings were found for anxiety symptoms except for treatment status, where the only significant effect was found when yoga was delivered during active treatment.

CONCLUSIONS

This review provides evidence that in people with cancer, yoga-based interventions are associated with amelioration of depression and anxiety symptoms and therefore a promising therapeutic modality for their management. However, the potential for risk of bias together with control group design challenges means the results should be interpreted with caution.
