Effects of home-based walking on cancer-related fatigue in patients with breast cancer: a meta-analysis of randomized controlled trials

Using Integrative Therapies to Improve Patient-Reported Outcomes in Breast Cancer Survivors: A Living Evidence-Based Clinical Practice Guideline

AIM

Breast cancer imposes a serious disease and economic burden on patients. This guideline aims to develop a living evidence-based clinical practice recommendations to guide the use of integrative therapies for the improvement of patient-reported outcomes (PROs) in breast cancer survivors.

METHODS

We searched systematic reviews and meta-analyses or conducted de nova systematic reviews and meta-analyses to support the recommendations. The grading of recommendations, assessment, development, and evaluation approach was used to rate the certainty of evidence and the strength of recommendations.

RESULTS

The guideline panel issued 17 recommendations: for alleviating anxiety, strong recommendations in favor of muscle relaxation training, yoga, acceptance and commitment therapy, cognitive behavioral therapy, psychological education, and Tai Chi in general breast cancer survivors; for alleviating depression, strong recommendations in favor of mindfulness therapy, cognitive behavioral therapy, group psychotherapy, muscle relaxation training, acceptanceand commitment therapy in general breast cancer survivors, and exercise intervention for patients received radiotherapy; for sleep quality, conditional recommendations for all therapies; for pain, strong recommendations in favor of exercise intervention for postoperative breast cancer survivors; for alleviating fatigue, strong recommendations in favor of mindfulness therapy and group psychotherapy in general breast cancer survivors; for improving the quality of life, strong recommendations in favor of mindfulness therapy in general breast cancer survivors, Baduanjin and exercise intervention for patients undergoing anticancer treatment.

CONCLUSION

This proposed guideline provides recommendations for improving the PROs of breast cancer survivors. We hope these recommendations can help support practicing physicians and other healthcare providers for breast cancer survivors.

Metastatic breast cancer patients' preferences for exercise programs: a latent class analysis using data from a survey in five European countries

PURPOSE

We aimed to identify metastatic breast cancer (MBC) patients' preferences for exercise programs and identify patients' characteristics associated with these preferences, to facilitate implementation of exercise programs for MBC patients.

METHODS

We used data from a multinational cross-sectional survey conducted among MBC patients. Patients reported their preferred exercise frequency, intensity, type, session duration, and supervision mode. We used latent class analysis to identify subgroups with similar preferences and descriptive statistics to compare demographic and clinical characteristics of patients within subgroups.

RESULTS

Four distinct classes were identified based on data from 409 participants. Class 1 (47% of participants) is characterized by a preference for moderate exercise with supervision within the health care setting. Most participants in this class had bone metastases. Class 2 (30%) is characterized by a preference for vigorous exercise with supervision. This class included participants who were, on average, younger, and had a higher education level. Class 3 (13%) is characterized by a preference for active walking. These participants were less likely to have bone metastases or comorbidities. Class 4 (10%) is characterized by a preference for recreational walking and included participants who were, on average, older, and less likely to be employed.

CONCLUSION

We identified four classes of patients with different preferences for exercise programs. Many patients with MBC express exercise preferences that meet the current guideline recommendations. Some patients with MBC may benefit from targeted education to align their preferences and behavior with the amount of exercise that is necessary to gain health benefits.

Home-based exercise interventions' impact on breast cancer survivors' functional performance: a systematic review

INTRODUCTION

Home-based exercise (HBE) programs can be a feasible strategy to enhance functional performance and promote physical activity (PA) in breast cancer survivors. A deeper analysis of the effects of HBE interventions, structured by HBE program type and treatment phase, is needed. This systematic review aimed to synthesize the evidence on HBE interventions' impact on breast cancer survivors' functional performance, PA levels, and program adherence rates, according to HBE intervention type and treatment phase.

METHODS

A comprehensive search of peer-reviewed articles reporting HBE interventions' effects on the outcomes of interest was performed in Pubmed, Google Scholar, EBSCO, Web of Science, Science Direct, and B-ON until January 15th, 2024. Data were synthesized according to Denton's domains to classify HBE interventions (prescription: structured vs. unstructured; Delivery method: supervised vs. facilitated vs. unsupervised) and treatment phase. Methodological quality appraisal was performed using the Effective Public Health Practice Project tool.

RESULTS

Twenty-six studies were included. Most studies conducted structured/facilitated interventions and reported positive effects on functional performance (particularly aerobic capacity), increases in PA levels, and high adherence rates (> 70%) during and post-treatment.

CONCLUSION

HBE interventions may be feasible to improve functional performance and promote physical activity among breast cancer survivors. Further studies are needed to confirm which HBE intervention type is more appropriate for each treatment phase. More evidence applying HBE interventions with different designs is required to allow the drawing of more solid conclusions. Studies exploring the effects of HBE interventions on the pre-treatment phase are needed.

Prescribing pre- and post-operative physical activity interventions for people undergoing breast cancer surgery: A qualitative systematic review

INTRODUCTION

Undertaking physical activity, pre- and post-operatively, can benefit recovery time and improve post-surgical outcomes. One cohort of patients that have reported these benefits are those undergoing surgery for breast cancer. Yet, what remains unclear is the level to which physical activity interventions are implemented into standard surgical care for patients with breast cancer.

AIMS

This systematic review aimed to examine existing qualitative evidence focusing on pre- and post-operative physical activity interventions to better understand the benefits and shortcomings of physical activity within the surgical journey.

METHODS

A systematic literature search was undertaken in November 2022, across five databases: MEDLINE, PsycINFO, Embase, CINAHL, and Scopus. Qualitative studies involving people with breast cancer who had undertaken a physical activity intervention, either pre- and/or post-operatively, were included for analysis. The review was registered on PROSPERO: CRD42022372466 and performed according to PRISMA guidelines. The Critical Appraisal Skills Programme qualitative study checklist was used to assess study quality.

RESULTS

Fourteen studies were included, comprising the perspectives of 418 people receiving surgery for breast cancer. One study implemented preoperative physical activity interventions; the remaining studies focused on post-operative interventions. A narrative systematic review was undertaken due to heterogeneity in reported results. Four themes were developed by thematic analysis, centring on: (1) factors promoting engagement with physical activity interventions; (2) factors preventing engagement with physical activity interventions; (3) the impact of pre- and post-operative interventions on physical and psychological health; and (4) participant recommendations for pre- and post-operative interventions.

CONCLUSION

Pre- and post-operative physical activity interventions were well-accepted. Patients recognised factors which promoted or prevented engagement with interventions, as well as pre- and post-operative physical and psychological benefits that arose as a result. Evidence based co-design studies may further inform successful implementation of prescribed physical activity into standard care for surgical breast cancer patients.

Implementation of a Mindful Walking Intervention in Breast Cancer Patients After Their Primary Oncologic Treatment: Results of a Qualitative Study Within a Randomized Controlled Trial

BACKGROUND

Breast cancer survivors often suffer from diagnosis- and therapy-related long-term side effects, such as cancer related fatigue, restricted stress resilience and quality of life. Walking as a physical activity and mindfulness practice have been shown to be helpful in studies. The aim of this study was to compare the individual experiences and subjectively perceived effects of walking in combination with mindfulness practice with moderate walking alone in breast cancer patients. This paper focuses on the qualitative results of a mixed-methods pilot study.

METHODS

Breast cancer patients who had finished their primary oncologic treatment at least 6 months ago were randomized to an 8-week group intervention program of either mindful walking or moderate walking. Within the qualitative study part, semi-structured focus group interviews (2 interviews per study arm) were conducted and analyzed using a qualitative content analysis approach. Audio recorded interviews were transcribed verbatim and pseudonymized. The subsequent data analysis was performed by using MAXQDA®.

RESULTS

A total of 51 women (mean age 55.8 [SD 10.9] years) were included in the RCT, among these 20 (mean age 56.7 [SD 12.0] years) participated in the focus group interviews (n = 11 patients of the mindful walking group; n = 9 patients of the walking group). Breast cancer patients in both groups described different effects in the complex areas of self-efficacy, coping, body awareness and self-reflection. While mindful walking primarily promoted body awareness and inner strength by mindfulness in breast cancer patients, moderate walking promoted self-efficacy by a confidence of their body and an easily integrated and accepted way of physical activity.

CONCLUSIONS

Study interventions and the study setting triggered processes and reflections on one's own health and situation. However, mindful walking and moderate walking seem to address different resources. This important knowledge may help oncologists and other therapists to assess what type of interventions can best meet the needs and requirements of individual patients.

Effects of Walking Combined With Resistance Band Exercises on Alleviating Cancer-Related Fatigue: A Systematic Review and Meta-analysis of Randomized Controlled Trials

BACKGROUND

Cancer-related fatigue (CRF) is a common symptom, and exercise has shown potential in alleviating CRF. However, there is a need for diverse exercise options tailored to individual patient needs.

OBJECTIVE

To evaluate the overall effects of a combined walking and resistance band exercise intervention in relieving CRF among cancer patients through randomized controlled trials.

METHODS

Comprehensive searches were conducted in multiple databases to identify relevant studies up until March 2023. Inclusion criteria required the intervention to involve walking combined with elastic band training, with a clear exercise protocol description. The primary outcome was CRF, and secondary outcomes included walking steps, distance, mood distress, and quality of life. Standardized mean differences (SMDs) with 95% confidence intervals (CIs) were calculated using random-effects models.

RESULTS

Ten trials were included. The intervention group showed significant improvements in CRF (SMD, -0.40; 95% CI, -0.60 to -0.20), mood distress (SMD, -0.30; 95% CI, -0.53 to -0.07), and daily walking steps (SMD, 0.52; 95% CI, 0.07-0.96) compared with the control group. Although the 6-Minute Walk Test and quality of life did not show significant differences, a trend toward improvement was observed in the intervention group. Adverse events related to the intervention were infrequent.

CONCLUSION

A combined walking and resistance band exercise intervention can effectively alleviate CRF and improve mood distress and daily walking steps among cancer patients.

IMPLICATIONS FOR PRACTICE

This exercise option may provide an additional strategy to manage CRF. Further research is needed to explore the optimal exercise prescription for individual patients.

The effectiveness of exercise on the symptoms in breast cancer patients undergoing adjuvant treatment: an umbrella review of systematic reviews and meta-analyses

Background

Exercise has the potential to reduce symptoms for breast cancer patients during adjuvant treatment, and high-quality systematic reviews are essential for guiding clinical practice. The objective of this umbrella review is to examine current research evidence concerning the effectiveness of exercise on symptom management in breast cancer patients undergoing adjuvant treatment.

Methods

An umbrella review was conducted. We searched for eligible systematic reviews through 11 databases until August 13rd, 2023. Two authors independently screened titles and abstracts, assessing the full-text studies based on inclusion criteria. We used AMSTAR-2 to appraise the quality of the meta-analyses. The results would be presented with narrative summaries if the replication rate of the original study for a symptom was higher than 5% (calculated via the Corrected Covered Area, CCA). The protocol was documented in the PROSPERO registry (CRD42023403990).

Results

Of the 807 systematic reviews identified, 15 met the inclusion criteria, and 7 symptoms were the main focus. The main form of exercise mentioned was aerobic combined resistance exercise. The results of the quality assessment were mostly critically low (10/15). The repetition rate calculated by CCA showed moderate to very high repetition rates (10% to 18.6%). The findings of the included reviews indicated that the effects of exercise on relieving symptoms during breast cancer adjuvant treatment were mixed.

Conclusions

Research is still needed to confirm the majority of studies' recommendations for exercise during adjuvant treatment for breast cancer patients, as it is crucial for managing symptoms in the rehabilitation process. To increase the efficiency of exercise in symptom management, future studies may focus more on the application of bridge symptoms, symptom networks, and ecological instantaneous assessment.

Nonpharmacological interventions for cancer-related fatigue: A literature review

Cancer-related fatigue (CRF) is a prevalent and debilitating side effect of cancer treatment that can persist for years posttreatment, significantly impacting patients' quality of life. Given the limited efficacy of pharmacological treatments, nonpharmacological interventions are gaining attention as effective management strategies for CRF. This review aims to provide an overview of the most common nonpharmacological interventions for CRF management, including exercise therapies, psychosocial interventions, sensory art therapy, light therapy, nutritional management, traditional Chinese medicine therapies, sleep management, combination therapy, and health education. By synthesizing the findings of high-quality literature, this review presents the definition of each therapy, along with their advantages and disadvantages in treating patients with CRF. Additionally, it addresses the role of oncology nurses in the nonpharmacological management of CRF. In summary, this review aims to inform oncology nurses about the prevalent nonpharmacological interventions for CRF and explore their clinical application to facilitate the development of effective CRF management strategies in clinical practice.

High-intensity exercise prescription guided by heart rate variability in breast cancer patients: a study protocol for a randomized controlled trial

BACKGROUND

Breast cancer is a chronic disease with a large growth in its treatments, prognosis, improvements, side effects and rehabilitation therapies research. These advances have also highlighted the need to use physical exercise as a countermeasure to reduce the cardiotoxicity of pharmacological treatments, increase patients' strength and quality of life and improve body composition, physical condition and mental health. However, new investigations show the need for a closed exercise individualisation to produce higher physiological, physical and psychological benefits in remote exercise programs. To this end, the present study will use, in a novel way in this population, heart rate variability (HRV) as a measure for prescribing high-intensity training. Thus, the primary objective of this randomised clinical trial is to analyse the effects of a high-intensity exercise program daily guided by HRV, a preplanned moderate to high-intensity exercise intervention and a usual care group, in breast cancer patients after chemotherapy and radiotherapy treatments.

METHODS

For this purpose, a 16-week intervention will be carried out with 90 breast cancer patients distributed in 3 groups (a control group, a moderate to high-intensity preplanned exercise group and a high-intensity exercise group guided by HRV). Both physical exercise interventions will be developed remotely and supervised including strength and cardiovascular exercises. Physiological variables, such as cardiotoxicity, biomarkers, lipid profile, glucose, heart rate and blood pressure; physical measures like cardiorespiratory capacity, strength, flexibility, agility, balance and body composition; and psychosocial variables, as health-related quality of life, fatigue, functionality, self-esteem, movement fear, physical exercise level, anxiety and depression will be measure before, after the intervention and 3 and 6 months follow up.

DISCUSSION

Personalized high-intensity exercise could be a promising exercise intervention in contrast to moderate-intensity or usual care in breast cancer patients to reach higher clinical, physical and mental effects. In addition, the novelty of controlling HRV measures daily may reflect exercise effects and patients' adaptation in the preplanned exercise group and a new opportunity to adjust intensity. Moreover, findings may support the effectiveness and security of physical exercise remotely supervised, although with high-intensity exercise, to reach cardiotoxicity improvements and increase physical and psychosocial variables after breast cancer treatments.

Effectiveness of exercise interventions in the management of cancer-related fatigue: a systematic review of systematic reviews

BACKGROUND

Cancer-related fatigue is a widely prevalent global public health concern with serious consequences. Increasing evidence suggests the effectiveness of exercise intervention in treating cancer-related fatigue, but there is a lack of a summary of relevant literature on the same to help reach a clear consensus.

OBJECTIVE

To summarize evidence regarding the efficacy of exercise interventions to reduce cancer fatigue, as determined in systematic reviews (SRs) and/or meta-analyses (MAs).

METHOD

From inception to September 2022, PubMed (1948-2022), Embase (1974-2022), Cochrane Library (1993-2022), CINAHL (1937-2022), Web of Science (1997-2022), China Knowledge Resource Integrated Database (1999-2022), Wanfang Database (1993-2022), and Chinese Biomedical Database (1994-2022) were searched for inclusion to the study. Two reviewers independently extracted the data from the included articles. AMSTAR II was to evaluate the methodological quality of the reviews.

RESULTS

A total of 46 systematic reviews were assessed for data on exercise intervention in reducing cancer-related fatigue among cancer patients. In addition, some studies have reported adverse events during the exercise intervention period. The quality of the included systematic review was found to be low or critically low.

CONCLUSIONS

The present systematic review of systematic reviews supports exercise intervention for reducing cancer-related fatigue. Further higher-quality studies are warranted to improve the level of evidence for exercise interventions for application in the treatment of cancer-related fatigue.
