Safety and feasibility of exercise interventions in patients with advanced cancer: a systematic review

A cross-sectional study exploring the perception of exercise oncology in the Italian population

Introduction

We aim to examine the population's perception of physical exercise in patients with cancer.

Materials and methods

An anonymous survey was conducted to reach a sample of Italian adults. The questionnaire investigated sociodemographic factors, physical exercise levels, and perceptions about the importance, benefits, and safety of exercise, the support from oncologists and family/friends, as well as the capability and ease of patients of exercise.

Results

Overall, 838 persons participated in this survey. The majority of respondents agree that exercise is important (60.5%) and beneficial (61.5%) for patients with cancer during anticancer treatments, whereas 40.2% believed in its safety. Forty-two percent and 51.9% of participants expressed a positive opinion regarding the advice of oncologists and the encouragement of family/friends to exercise, respectively. Only 27.2% of respondents feel that patients are capable of exercising, and 9.0% agree that it is easy for them.

Conclusion

Although the population has a favorable perception of the importance and benefits of physical exercise, they do not still believe that patients are capable of performing it. Increasing awareness of the feasibility of a physical exercise intervention in the context of cancer is crucial to supporting patients.

Developing a Sitting Simple Baduanjin program for advanced cancer patients with the fatigue-sleep disturbance symptom cluster: A feasibility study

OBJECTIVES

We describe a development and feasibility study of a Sitting Simple Baduanjin program for advanced cancer patients suffering from the fatigue-sleep disturbance symptom cluster. This study was to evaluate the practicality and safety of the Sitting Simple Baduanjin intervention and determine its preliminary efficacy.

METHODS

This work employed a single-arm mixed-methods approach. The primary outcome measures were feasibility (i.e., recruitment, adherence, and satisfaction) and safety. Validated self-report questionnaires were used to evaluate the preliminary effects of the program, including fatigue, sleep quality, and quality of life at the 4th, 8th, and 12th weeks of the intervention. Qualitative interviews were also conducted after the program.

RESULTS

A total of 30 participants were enrolled, of which 23 (77%) completed the 12-week Sitting Simple Baduanjin program. The mean adherence rate was 88% and no adverse events were reported. Statistically significant improvements were observed in terms of fatigue, sleep quality, and quality of life after program completion. Four themes emerged from the qualitative interview data: (a) acceptability of the Sitting Simple Baduanjin technique, (b) perceived benefits of exercise, (c) barriers, and (d) facilitators.

SIGNIFICANCE OF RESULTS

The findings support the feasibility of the Sitting Simple Baduanjin program for advanced cancer patients and show promise in improving patients' levels of the fatigue-sleep disturbance symptom cluster and quality of life.

Simple Sitting Baduanjin mind-body exercise: randomized controlled trial protocol for advanced cancer patients with the fatigue-sleep disturbance symptom cluster

BACKGROUND

Advanced cancer patients commonly suffer from a fatigue-sleep disturbance symptom cluster. Baduanjin is considered a promising mind-body exercise for relieving the fatigue-sleep disturbance symptom cluster. However, few studies have investigated a tailored Baduanjin for advanced cancer patients. The proposed study will create an optimized Baduanjin exercise program to adapt to advanced cancer patients and evaluate the effect of a Simple Sitting Baduanjin (SSBDJ) mind-body exercise on the fatigue-sleep disturbance symptom cluster among advanced cancer patients.

METHODS

The study will be a prospective, assessor-blinded, two-arm, randomized controlled trial, involving a 12-week intervention and 4-week follow-up. A total of 108 advanced cancer patients experiencing the fatigue-sleep disturbance symptom cluster will be recruited from two tertiary general hospitals in China. Participants will be randomized to an experimental group (n = 54) or a control group (n = 54). The experimental group will receive a 12-week SSBDJ intervention plus the usual care, and the control group will receive only the usual care. Outcomes including fatigue-sleep disturbance symptom cluster, fatigue, sleep disturbance, and quality of life will be measured before the intervention, at the 4th, 8th, and 12th weeks of the intervention, and 4 weeks after the intervention. The intention-to-treat principle and a generalized estimating equation will be used to analyze data.

DISCUSSION

This study may produce a new Baduanjin exercise prescription that is user-friendly, simple to execute, more targeted, and adaptable. If proven effective, this approach may be integrated into routine cancer care to manage the fatigue-sleep disturbance symptom cluster and improve QOL in advanced cancer patients.

The Physical Activity and Cancer Control (PACC) framework: update on the evidence, guidelines, and future research priorities

BACKGROUND

We proposed the Physical Activity and Cancer Control (PACC) framework in 2007 to help organise, focus, and stimulate research on physical activity in eight cancer control categories: prevention, detection, treatment preparation/coping, treatment coping/effectiveness, recovery/rehabilitation, disease prevention/health promotion, palliation, and survival.

METHODS

This perspective paper provides a high-level overview of the scientific advances in physical activity research across cancer control categories, summarises current guidelines, updates the PACC framework, identifies remaining and emerging knowledge gaps, and provides future research directions.

RESULTS

Many scientific advances have been made that are reflected in updated physical activity guidelines for six of the cancer control categories apart from detection and palliation. Nevertheless, the minimal and optimal type, dose, and timing of physical activity across cancer control categories remain unknown, especially for the understudied population subgroups defined by cancer type, age, race/ethnicity, and resource level of regions/countries.

CONCLUSION

To achieve the full benefit of physical activity in cancer control, future research should use innovative study designs that include diverse at-risk populations and understudied cancer sites. Additionally, effective behaviour change strategies are needed to increase physical activity levels across populations that use implementation science to accelerate the translation from evidence generation into practical, real-world interventions.

Lifestyle Behaviors in Patients With Gastric Cancer: Continuous Need for Alcohol Abstinence and Muscle Strength Training Education

PURPOSE

This study was performed to assess the lifestyle-related behaviors of patients with gastric cancer (GC) and to investigate the associations between the time since GC diagnosis and these behaviors.

MATERIALS AND METHODS

This study included 29,478 adults (including 338 patients with GC) aged ≥ 40 years who participated in the Korea National Health and Nutrition Examination Survey 2014-2021. Multiple logistic regression analysis explored the associations between the time since GC diagnosis (patients diagnosed with GC less than 5 years ago [<5 years group] and those diagnosed with GC 5 or more than years ago [≥5 years group]) and lifestyle factors. Subgroup analyses were conducted based on age and sex.

RESULTS

The current smoking rate was not lower in the GC group than in the healthy group, regardless of time since diagnosis. Compared to the healthy controls, monthly alcohol intake was lower in the <5 years group (odds ratio [OR], 0.450; 95% confidence interval [CI], 0.275-0.736). The ≥5 years group showed a lower rate of strength training (OR, 0.548; CI, 0.359-0.838), compared with the healthy control group. Subgroup analysis focusing on the ≥5 years group revealed a significantly lower rate of strength training, particularly in patients aged ≥65 years and male patients (OR, 0.519 and 0.553; CI, 0.302-0.890 and 0.340-0.901, respectively).

CONCLUSIONS

Clinicians should continue educating patients on lifestyle behavior modifications, particularly alcohol abstinence, even beyond 5 years after GC diagnosis. Education on strength training is especially important for patients ≥65 years or male patients.

Characteristics and Frequency of Physical Activity and Exercise-Related Side Effects in People Receiving Peritoneal Dialysis

OBJECTIVE

People receiving peritoneal dialysis may receive health benefits from physical activity or exercise. However, on-going uncertainty and fear regarding safety may result in this population missing out on the health benefits of participation. The aim of this study was to explore the characteristics and frequency of physical activity and/or exercise-related side effects (e.g., symptoms such as pain or shortness of breath) and negative health events (e.g., stroke or hyper/hypoglycemia) experienced by people receiving peritoneal dialysis.

METHODS

An international online survey involving adults receiving peritoneal dialysis was conducted with questions related to nature, occurrence, and impact of side effects and/or negative health events experienced during or soon after participation in physical activity or exercise.

RESULTS

Fifty-two people completed the survey reporting 151 side effects that were related to physical activity and exercise and 67 that were possibly related. Fatigue (58% of respondents), muscle/joint soreness or pain (54%), and dizziness (43%) were the most frequently reported side-effect types. The majority occurred occasionally (58% of all side effects), if not rarely (24%) and participation in on-going physical activity or exercise was typically prevented only occasionally (39%) or not at all (31%). Side effects were mainly self-managed (54% of all side effects) or did not require treatment (19%) and had low (38%) or no effect (30%) on ability to do daily activities.

CONCLUSIONS

People receiving peritoneal dialysis generally experience side effects that can be considered a normal response to physical activity or exercise engagement. Furthermore, the risk of serious or peritoneal dialysis-specific side effects as a result of physical activity or exercise appears to be low. The results add to the emerging evidence suggesting physical activity and exercise appear to be safe for people receiving peritoneal dialysis.

Exercise oncology clinical trials during treatments: a commentary to address the safety concerns of human subjects regulatory reviewers and committees

Exercise oncology clinical trials contribute to the advancement of our scientific knowledge and to the safety and care of patients diagnosed with cancer. Nevertheless, regulatory reviewers and committees may not be familiar with the well-documented long-term health benefits and safety of the regular practice of physical activity. Moreover, they may not see how the benefits outweigh the risks in the context where patients diagnosed with cancer are typically seen as vulnerable. Therefore, we would like to provide a purpose-built overview of exercise oncology clinical trials for members involved in institutional review committees, including the Scientific Review Committee (SRC), the Institutional Review Board (IRB), and the Data Safety Monitoring Committee (DSMC) to facilitate a greater understanding of the safety and benefits of physical activity during cancer treatments. Communication is key to improve the success of exercise oncology clinical trials, which are vital for patients diagnosed with cancer.

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

PURPOSE

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

MATERIALS AND METHODS

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

RESULTS

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

CONCLUSION

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

Feasibility metrics of exercise interventions during chemotherapy: A systematic review

BACKGROUND

Exercise has been shown to play an important role in managing chemotherapy-related side effects, preserving skeletal muscle mass, and attenuating decline in cardiorespiratory fitness associated with chemotherapy treatment, however, the feasibility of how these exercise programs are being delivered has yet to be synthesized. The objective of this review was to measure the rates of recruitment, adherence, and retention to exercise programs delivered for cancer patients during chemotherapy.

METHODS

Relevant studies were identified through a search of MEDLINE, Cochrane, EMBASE and CINAHL databases from January 2002 to July 2022 using keywords relating to exercise interventions during chemotherapy. Title and abstract screening, full text review, data extraction, and quality assessment were all performed independently by two reviewers.

RESULTS

A total of 36 studies were included in the review. The mean recruitment rate for the included studies was 62.39% (SD = 19.40; range 25.7-95%). Travel was the most common reason for declining recruitment in these trials. Adherence rates ranged from 17-109%, however the definition of adherence varied greatly between studies. Mean retention rates for the exercise groups was 84.1% (SD = 12.7; range 50-100%), with chemotherapy side effects being the most common reason why participants dropped out of these trials.

CONCLUSION

Multiple challenges exist for cancer patients during chemotherapy and careful consideration needs to be given when designing an exercise program for this population. Future research should include public and patient involvement to ensure exercise programs are pragmatic and patient centred.

Safety, Feasibility, and Acceptability of a Multisite Individualized Exercise Intervention for People with Multiple Myeloma

INTRODUCTION

High rates of disease- and treatment-related symptoms, such as bone lesions, in people with multiple myeloma (MM) create uncertainty on the safety and feasibility of exercise. This study determined the safety, feasibility, and acceptability of an individualized exercise medicine program for people with MM at any disease stage.

METHODS

A multisite, randomized waitlist-controlled trial was conducted of an individualized, high-intensity aerobic, resistance, and impact-loading exercise program. The exercise sessions were supervised twice weekly by accredited exercise physiologists, with one additional unsupervised session per week, for 12 wk. Safety was determined by number of adverse and serious adverse events. Feasibility outcome measures were study eligibility, recruitment, adherence, and attrition. Acceptability was determined by qualitative interviews and subjective levels of enjoyment.

RESULTS

Of 203 people with MM screened, 88% were eligible, with 34% accepting participation (60 people) and 20% attrition for the between-group analysis, meeting a priori criteria (≥25% and <25%, respectively). No adverse or serious adverse events attributed to testing and/or exercise training were reported. Attendance at supervised exercise sessions was 98%, with 45% completion of the home-based exercise sessions. Adherence rates were 35%, 63%, and 34% for the aerobic, resistance, and impact-loading protocols, with 55%, 80%, and 37% of participants meeting a priori criteria (75% of protocol). Acceptability of the exercise program was high (mean, 82%; 95% confidence interval, 78%-87%) and highly supported by qualitative responses.

CONCLUSIONS

An individualized, high-intensity aerobic, resistance, and impact-loading exercise medicine program is safe and acceptable, and feasible by some measures for people with MM. Adherence to the prescribed exercise protocols was limited by comorbidities and disease symptoms. Strategies to improve unsupervised exercise completion are warranted in this population.

Efficacy and Feasibility of Presurgical Exercise in Bladder Cancer Patients Scheduled for Open Radical Cystectomy

PURPOSE

This study aimed to examine the feasibility and potential efficacy of presurgical exercise in patients with bladder cancer scheduled for open radical cystectomy with follow-up postsurgery.

METHODS

Prospective single-group design with assessments at baseline, presurgery, and 3 months postsurgery was used in this study. Multimodal supervised resistance and aerobic exercise was undertaken 2-3 d·wk -1 at moderate intensity for a median of 3.5 wk (interquartile range [IQR] = 1.3-5.6). Feasibility was assessed by recruitment and completion rates, patient safety, program tolerance, adherence, and compliance. Lean and fat mass were assessed by dual-energy x-ray absorptiometry, physical function by a battery of tests (chest press and leg press strength, 6-min walk test [6MWT], timed up-and-go, repeated chair rise), and quality of life (QoL), psychological distress, and body image by questionnaire. Hospital length of stay (LOS) and complications were assessed by medical records.

RESULTS

Thirty-seven patients were referred with 20 recruited (67.3 ± 12.2 yr) and a presurgery intervention completion rate of 80% (16 of 20). The individual median program adherence was 100.0% (IQR = 89.4-100.0) with compliance of 100.0% (IQR = 90.5-100.0) for resistance exercise and 81.8% (IQR = 55.0-99.5) for aerobic exercise. There were no exercise-related adverse events. Body composition did not change presurgery; however, there were improvements ( P < 0.05) in leg press strength (16%), 6MWT distance (8%), timed up-and-go (12%), chair rise (10%), and multiple QoL domains including mental health. Median LOS was 8.0 d (IQR = 7.0, 15.0). Postsurgery, there were declines in components of QoL and apparent body image dissatisfaction.

CONCLUSIONS

A preradical cystectomy exercise program is feasible, safe, and well tolerated with improvements in physical function and QoL. Supervised multimodal exercise in bladder cancer patients before cystectomy can enhance physical and mental health potentially buffering the effects of surgery.

Effect of Exercise Training on Quality of Life, Symptoms, and Functional Status in Advanced-Stage Lung Cancer Patients: A Systematic Review

Advanced-stage lung cancer (LC) causes significant morbidity and impacts patients' quality of life (QoL). Exercise has been proven to be safe, feasible, and beneficial for symptom reduction and QoL improvement in many types of cancers, but research is limited in advanced-stage LC patients. This systematic review evaluates the effect of exercise interventions on the symptoms and QoL in patients with advanced-stage LC. Twelve prospective studies (744 participants) were included, evaluating different combinations of exercises and training such as aerobics, tai chi, strength, inspiratory muscle training, and relaxation. Studies found outcomes including but not limited to improved QoL, symptom burden, psychosocial health, functional status, and physical function. The results of this review support that exercise is safe and feasible with evidence supporting improved QoL and symptom mitigation. Integration of exercise should be considered in the individualized management of advanced-stage LC patients under the guidance of their healthcare providers.

Feasibility of supervised telehealth exercise for patients with advanced melanoma receiving checkpoint inhibitor therapy

PURPOSE

To determine the feasibility, safety and preliminary efficacy of a telehealth supervised exercise programme in patients with advanced melanoma receiving checkpoint inhibitor therapy.

METHODS

A 8-week non-randomised feasibility pilot trial utilising a telehealth delivered multimodal exercise programme undertaken thrice weekly with assessments at baseline and post-intervention. The study was considered feasible if there were no severe or life-threatening adverse events as a result of exercise, and three or more of the following criteria were met: the recruitment rate was >50%, completion rate was >80%, median programme attendance was >75%, median exercise compliance >75%, and average tolerance was >70%. Preliminary efficacy was assessed for objective measures of physical function (2-min step test, repeated chair stand test, 30-s push-up test, and a modified static balance test) and quality of life (QoL), fatigue and other patient-reported outcomes were assessed using the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire Core 30.

RESULTS

Eleven patients (32-80 years) were included in the study (6 female, 5 male). The recruitment rate was 48%, completion rate 91%, programme attendance 88%, median exercise compliance 82.1% and 84.9% for resistance and aerobic exercise, respectively, and tolerance 88%, with no severe or life-threatening adverse events as a result of exercise. In terms of preliminary efficacy, physical function significantly improved while QoL was maintained following the intervention.

CONCLUSION

An 8-week telehealth exercise intervention is feasible and safe for patients with advanced melanoma and appears to improve physical function while preserving QoL during checkpoint inhibitor therapy.

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.

Adherence, safety, and satisfaction of a cardio-oncology rehabilitation program framework versus community exercise training for cancer survivors: findings from the CORE trial

PURPOSE

To assess safety, satisfaction, and overall adherence of a center-based cardiac rehabilitation (CBCR) program for cancer survivors at increased cardiovascular (CV) risk, compared to community-based exercise training (CBET).

METHODS

The CORE study was a single-center, prospective, randomized controlled trial enrolling cancer survivors exposed to cardiotoxic cancer treatment and/or with previous CV disease. Participants were randomized to an 8-week CBCR program or CBET, twice a week. Overall feasibility (consent, retention, and completion rates), intervention adherence (percentage of exercise sessions attended), and safety were assessed. Adverse events (AEs) were registered, and participants' satisfaction was measured at the end of the study.

RESULTS

Eighty out of 116 potentially eligible individuals were included; consent rate was 72.4%, and 77 (96.2%) started the study (retention rate 100% in CBCR vs 92.5% in CBET); completion rate was 92.5%. Intervention adherence was higher in CBCR (90.3 ± 11.8% vs 68.4 ± 22.1%, p < 0.001). Exercise-related AEs were mainly related to musculoskeletal conditions in both groups (7 in CBCR vs 20 in CBET, p < 0.001), accounting for exercise prescription modification in 47 sessions (18 (3.3%) in CBCR vs 29 (7.2%) in CBET, p = 0.006), none motivating exercise discontinuation. No participants reported major CV events. Overall, the satisfaction with the different aspects of the programs (e.g., expectations, monitoring) was higher in the CBCR.

CONCLUSION

This exploratory analysis of the CORE trial suggests that both exercise-based interventions are feasible and safe in this setting. The higher intervention adherence and patient satisfaction in CBCR suggest that this comprehensive approach could be of interest in this population.

Safety, Feasibility, and Efficacy of Exercise Interventions for People With Multiple Myeloma: A Systematic Review

Bone lesions and other disease- and treatment-related side effects commonly experienced by people with multiple myeloma (MM) may impede their ability to exercise. This systematic review evaluated the safety, feasibility, and efficacy of exercise program participation on the physiological and/or psychological health of people with MM. Literature searches were conducted through five electronic databases and appraised using the Delphi list of criteria. Controlled trials that assessed the safety and feasibility of an exercise intervention and its effects on disease- or treatment-related symptoms in people with MM were included. Seven studies of varying quality involving 563 participants were included. All studies concluded that exercise was safe, reporting zero serious and 4 adverse events attributable to exercise testing or training. Attendance ranged from 58% to 96%, however no study reported adherence to the exercise prescription. Compared to a control group, exercise did not appear to affect fatigue, depression, anxiety, body composition, quality of life, or sleep. Isolated studies identified between-group differences favoring exercise in lower limb strength (+8.4 kg, 95% CI 0.5, 16.3, P= .04), peak oxygen uptake (+1.2 mL/kg/min, 95% CI 0.3, 3.7, P= .02), physical activity (+6.5MET-hs/wk, P< .001), stem cell collection attempts (1.1 ± 0.2 vs. 1.5 ± 0.9, P< .01), and red blood cell (1.8 ± 2.2 vs. 2.4 ± 2.6, P< .05) and platelet transfusions (2.3 ± 1.6 vs. 3.5 ± 3.4, P < .05) during transplantation. Exercise interventions appear safe and well attended by people with MM. The lack of improvements in disease- and treatment-related symptoms requires further exploration to determine whether exercise is a sufficient stimulus to elicit benefits in this unique population.

Effects of a prescribed, supervised exercise programme on tumour disease progression in oncology patients undergoing anti-cancer therapy: a retrospective observational cohort study

BACKGROUND

Exercise promotes numerous advantages in both health and disease, and is increasingly being acknowledged to improve overall survival in cancer patients. Preclinical studies indicate a direct effect on tumour behaviour, but human data on the effect of exercise on tumour progression are lacking.

AIMS

To capture preliminary clinical data regarding the impact of a prescribed, supervised exercise programme on cancer disease progression.

METHODS

Retrospective cohort study of 137 matched pairs of patients. All patients referred to LIFT Cancer Care Services (LIFT) supervised exercise programme between 2018 and 2019 were matched with non-LIFT patients from the oncology practice database. Disease progression via staging computed tomography scans ± tumour markers was compared for each match. Secondary outcomes were changes in neutrophil-to-lymphocyte ratio (NLR) and death. Results were analysed by logistical regression and adjusted for potential confounders.

RESULTS

Patients from the LIFT group had a 66% (OR = 0.34, 95% CI 0.19 to 0.61) decreased odds of disease progression and 76% (OR = 0.24, 95% CI 0.12-0.47) decreased odds of death compared with the non-LIFT group. No effect on the number of LIFT sessions on disease progression was demonstrated. The LIFT group had a mean final NLR reading 3.48 (-5.89 to -1.09) lower than the non-LIFT group.

CONCLUSION

Supervised exercise programmes have the potential to significantly improve outcomes in cancer patients due to an effect on tumour progression.

[Complementary or alternative medicine in oncology : Chances or risks?]

BACKGROUND

Approximately half of all cancer patients use complementary or alternative medicine.

AIM

The results of the German S3 guidelines on complementary oncology are presented and placed into the context of patient consultation.

MATERIAL AND METHODS

The core recommendations of the S3 guidelines are summarized including an overview of the evidence.

RESULTS

Selected methods of complementary medicine can be used with the aim of improving the quality of life and reducing side effects. Comprehensive data are available for physical activity with respect to survival, quality of life and supportive therapy. For most other methods the evidence is relatively low. Therefore, weighing up the benefits and risks more frequently resulted in negative recommendations in the guidelines, especially for methods based on substances. Exceptions to this are three micronutrients (vitamins B12, D and selenium), as even in the case of a well-balanced diet, deficiency symptoms are possible. Therefore, routine measurement of the blood levels of these micronutrients is recommended.

CONCLUSION

The questions from patients on what they can do by themselves should be answered respectfully and based on evidence. The benefits and risks of complementary methods must be carefully considered. To do this, regular questioning of patients on the interest in complementary methods is recommended. The decisive benefit of complementary medicine is the chance for patients to become active themselves. Therefore, all recommendations refer to the discussion with the patient, which do not formulate a therapy but are consultation recommendations: should be recommended instead of should be done.

Feasibility, Safety, and Preliminary Efficacy of Very Low-Volume Interval Training in Advanced Cancer Patients

PURPOSE

High-intensity interval training (HIIT) has been shown to improve cardiorespiratory fitness (CRF) and health-related outcomes in various chronic diseases, including cancer. However, data on feasibility and efficacy of HIIT in advanced cancer patients are still sparse, presumably because of safety concerns, like suspected immunosuppression after vigorous exercise. This randomized, sham-intervention controlled study aimed to investigate feasibility, safety, and preliminary efficacy of very low-volume HIIT (LOW-HIIT) in advanced cancer patients.

METHODS

Twenty-seven patients (55.4 ± 13.2 yr) with different advanced cancers (Union for International Cancer Control [UICC] III/IV) were randomly allocated to LOW-HIIT ( n = 13), consisting of 5 × 1 min cycle ergometer intervals (14 min per session total duration) at 80% to 95% HR peak (two sessions per week for 12 wk), or a sham intervention ( n = 14) performing light physical mobilization exercises (SHAM). Primary outcomes were attrition and attendance rates, with values of ≤25% and ≥80%, respectively, considered acceptable. Secondary outcomes were safety, protocol fidelity, physiological (including CRF measures) and patient-reported outcomes (including fatigue and quality of life).

RESULTS

One of 13 patients (8%) receiving LOW-HIIT dropped out. Mean attendance rate was ~93%. The prescribed minimum exercise intensity was consistently reached by all patients. Low-volume HIIT was well tolerated and not associated with any serious adverse event nor with increased infection susceptibility. There were no biochemical signs of acute immunosuppression after LOW-HIIT. Contrarily, differentiation and degranulation of natural killer cells was acutely increased postexercise. Low-volume HIIT improved CRF measures including peak oxygen uptake, self-reported fatigue, physical, and social functioning. No significant changes occurred in the SHAM group.

CONCLUSIONS

Low-volume HIIT can be regarded as feasible and safe in advanced cancer patients. Our preliminary data indicate favorable acute effects on NK-cells and beneficial chronic adaptations in CRF, fatigue, and aspects of quality of life.

Bewegungstherapie bei nicht-heilbaren, fortgeschrittenen Krebserkrankungen

Dank der Entwicklung neuer Chemotherapie-Protokolle und verbesserter zielgerichteter Therapiestrategien hat sich das Überleben von Patienten mit nicht-heilbaren, fortgeschrittenen Krebserkrankungen deutlich verlängert. Durch die krankheitsbedingten Symptome und die zusätzlichen therapiebedingten Nebenwirkungen wird die Lebensqualität dieser Patienten aber deutlich eingeschränkt. Übersichtsarbeiten zeigen, dass auch Patienten mit nicht-heilbaren, fortgeschrittenen Krebserkrankungen von angepasster Bewegungstherapie profitieren können. Es wurde eine Literaturrecherche mithilfe elektronischer Datenbanken (PubMed, MEDLINE, EMBASE, Cochrane Library) durchgeführt und eine Übersicht der randomisierten kontrollierten Studien (RCTs) zur Bewegungstherapie bei nicht-heilbaren, fortgeschrittenen Krebserkrankungen gegeben. Die dargestellten Studien zeigen, dass eine gezielte Bewegungstherapie bei Patienten mit nicht-heilbaren, fortgeschrittenen Krebserkrankungen sicher und durchführbar ist und positive Effekte auf die Lebensqualität, auf krankheits- und therapiebedingte Symptome wie Fatigue, Dyspnoe und auf den körperlichen Funktionsstatus erzielen kann. Der Artikel beinhaltet außerdem einen Diskurs mit einem Praxisbezug zum Thema Knochenmetastasen.

Cardiovascular and metabolic determinants of quality of life in patients with cancer

AIMS

Maintaining quality of life (QoL) in patients with cancer has gathered significant interest, but little is known about its major determinants. We sought to identify determinants of QoL in patients undergoing cancer treatment as well as in treatment-naïve patients about to commence such therapy.

METHODS AND RESULTS

QoL was assessed in 283 patients with cancer using the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 questionnaire. All patients underwent a battery of tests including physical examination, resting electrocardiogram, hand grip strength, and biochemistry assessment. Using multivariable logistic regression, we found that age [odds ratio (OR) 0.954, 95% confidence interval (CI) 0.916-0.994], resting heart rate (OR 1.036, 95% CI 1.004-1.068), hand grip strength (OR 0.932, 95% CI 0.878-0.990), and the presence of cachexia (OR 4.334, 95% CI 1.767-10.631) and dyspnoea (OR 3.725, 95% CI 1.540-9.010; all P < 0.05) remained independently predictive of reduced QoL.

CONCLUSIONS

Therefore, it may be reasonable to address circumstances that are affecting muscle mass, body weight, and heart rate to maintaining QoL; however, prospective studies to test these endpoints are required.

Promoting moderate-to-vigorous physical activities in patients with advanced lung cancer: preferences and social cognitive factors, and the mediating roles

PURPOSE

The purpose of this study is to assess the prevalence and preferences of moderate-to-vigorous physical activities (MVPA) in patients with advanced lung cancer, explore the social cognitive factors that were associated with MVPA and interest in PA counseling and program, and examine the mediating role of social cognitive factors.

METHODS

This was a cross-sectional study. Questionnaires on PA levels, PA counseling and programming preferences, and social cognitive variables (social support and self-efficacy) were administered to 105 patients with advanced lung cancer. Linear regression model was used to explore the social cognitive factors associated with MVPA, and logistic regression model was used to explore the factors associated with interest in PA counseling and program. Mediation analysis was used to examine the mediating role of self-efficacy on social support and MVPA.

RESULTS

Merely 30.5% of patients met the recommended level of MVPA; however, the majority of patients (89.5%) were interested in PA program. Social support (β = 0.60; p = 0.007) and self-efficacy (β = 1.06; p = 0.027) were positively associated with MVPA. Specifically, self-efficacy mediated the relationship between social support and MVPA (β = 0.63, p = 0.004).

CONCLUSION

The majority of the patients with advanced lung cancer did not meet the recommended level of MVPA; however, they are interested in receiving PA counseling and joining PA programs. Social support was key to promoting higher levels of MVPA, and the association was mediated by self-efficacy. The established mediating model provides insights into designing PA programs and targeting the mediating variable, self-efficacy, to enhance the level of MVPA.

Exercise, Diet, and Weight Management During Cancer Treatment: ASCO Guideline

PURPOSE

To provide guidance on exercise, diet, and weight management during active cancer treatment in adults.

METHODS

A systematic review of the literature identified systematic reviews and randomized controlled trials evaluating the impact of aerobic and resistance exercise, specific diets and foods, and intentional weight loss and avoidance of weight gain in adults during cancer treatment, on quality of life, treatment toxicity, and cancer control. PubMed and the Cochrane Library were searched from January 2000 to May 2021. ASCO convened an Expert Panel to review the evidence and formulate recommendations.

RESULTS

The evidence base consisted of 52 systematic reviews (42 for exercise, nine for diet, and one for weight management), and an additional 23 randomized controlled trials. The most commonly studied types of cancer were breast, prostate, lung, and colorectal. Exercise during cancer treatment led to improvements in cardiorespiratory fitness, strength, fatigue, and other patient-reported outcomes. Preoperative exercise in patients with lung cancer led to a reduction in postoperative length of hospital stay and complications. Neutropenic diets did not decrease risk of infection during cancer treatment.

RECOMMENDATIONS

Oncology providers should recommend regular aerobic and resistance exercise during active treatment with curative intent and may recommend preoperative exercise for patients undergoing surgery for lung cancer. Neutropenic diets are not recommended to prevent infection in patients with cancer during active treatment. Evidence for other dietary and weight loss interventions during cancer treatment was very limited. The guideline discusses special considerations, such as exercise in individuals with advanced cancer, and highlights the critical need for more research in this area, particularly regarding diet and weight loss interventions during cancer treatment.Additional information is available at www.asco.org/supportive-care-guidelines.

Safety, feasibility, and effectiveness of implementing supervised exercise into the clinical care of individuals with advanced cancer

OBJECTIVE

To evaluate the safety, feasibility, and preliminary effectiveness of implementing supervised exercise programming into the clinical care of individuals with advanced cancer.

DESIGN

Single group implementation feasibility study using a pre-posttest design.

SETTING

Exercise Oncology Unit of the Spanish Cancer Association (a cancer-specific community facility outside the hospital setting).

PARTICIPANTS

Adult individuals with advanced cancer profile involving advanced local cancer or distant metastases.

INTERVENTION

A 12-week, twice-weekly, supervised, clinic-based multi-component exercise program.

MAIN MEASURE

Paired t-tests were used to assess pre-post changes and analyses of covariance were used to compare effects based on selected participant characteristics.

RESULTS

Eighty-four individuals with advanced cancer completed the baseline assessment, with six participants withdrawing prior to the start of the program. Of the 78 participants, 17 dropped out, thus, a total of 61 completed the final assessment. Mean adherence was 82.5%. No serious adverse events occurred. Exercise significantly improved VO_2max by 5.2 mL·kg·min (p < 0.001), chest strength (p < 0.001), leg strength (p < 0.001), lean body mass (p  =  0.003), skeletal muscle mass (p < 0.002), % body fat (p  =  0.02), quality of life by 5.3 points (p  =  0.009), fatigue by 3.2 points (p  =  0.012), and physical activity by 1680 METs/week (p < 0.001).

CONCLUSIONS

Our clinically supervised and tailored exercise program involving moderate to vigorous intensity exercise was found to be feasible, safe, and effective for individuals with advanced cancer.

IMPLICATIONS FOR CANCER SURVIVORS

With proper screening and supervision, individuals with advanced cancer can benefit from tailored exercise oncology support as part of an overall therapeutic care plan.

Physical exercise and fatigue in advanced gastrointestinal cancer during chemotherapy

OBJECTIVES

This study was aimed to analyse the effect of a patient-oriented modality of physical exercise (programmed and directed physical exercise (PDPE)) on cancer-related fatigue (CRF) and quality of life (QoL). The secondary aim was to evaluate changes in body composition and skeletal muscle function during the study in patients with and without PDPE.

METHODS

A prospective randomised study was conducted to analyse the impact of PDPE on CRF and QoL. Patients were selected before the development of CRF to set the intervention before its appearance. A high probability CRF population was chosen: patients with advanced gastrointestinal cancer undergoing chemotherapy with weight loss (≥5%) over the last 6 months. PDPE consisted of a programme of exercise delivered weekly and adjusted to patients' medical conditions. Four visits were planned (weeks 0, 4, 8 and 12). QoL, CRF, body composition and skeletal muscle function were evaluated in each visit.

RESULTS

From 101 patients recruited, 64 were considered evaluable, with three or four visits completed (n=30 control, n=34 PDPE group). Satisfactory compliance of ≥50% to the PDPE programme was seen in 47%. A reduction in the severity of fatigue was detected in the PDPE group (p=0.019), being higher in the subgroup of satisfactory compliance (p<0.001). This latter group showed better results of QoL in comparison with the control group (p=0.0279). A significant increase in endurance was found in the PDPE group (p<0.001).

CONCLUSION

PDPE reduced the severity of fatigue and improved QoL. The difference in endurance would explain the results seen in the severity of fatigue.

Efficacy of resistance training during adjuvant chemotherapy and radiation therapy in cancer care: a systematic review and meta-analysis

PURPOSE

To determine the effect of resistance training during adjuvant chemotherapy and radiation therapy in cancer patients on measures of lean mass and muscle strength. Secondary aims were to analyse the prescription and tolerability of supervised resistance training in this population.

METHODS

EMBASE, Medline, CINAHL, Cochrane Library and Web of Science were searched from inception until 29 March 2021. Eligible randomised controlled trials (RCTs) examining supervised resistance training > 6 weeks duration during adjuvant chemotherapy and/or radiation therapy in cancer patients with objective measurement of muscle strength and/or lean mass were included. The meta-analysis was performed using Revman 5.4.

RESULTS

A total of 1910 participants from 20 articles were included (mean age: 54 years, SD = 10) and the majority were female (76.5%). Resistance training was associated with a significant increase in upper body strength (standardised mean difference (SMD) = 0.57, 95% CI 0.36 to 0.79, I2 = 64%, P < 0.0001), lower body strength (SMD = 0.58, 95% CI 0.18 to 0.98, I2 = 91%, P = 0.005), grip strength (mean difference (MD) = 1.32, 95% CI 0.37 to 2.27, I2 = 0%, P < 0.01) and lean mass (SMD = 0.23, 95% CI 0.03 to 0.42, I2 = 0%, P = 0.02). A P value of < 0.05 was considered statistically significant. The quality of the studies included was moderate to high with low risk of bias as per the PEDro scale.

CONCLUSION

Resistance training is an effective adjunct therapy to improve muscle strength and lean mass in cancer patients undergoing chemotherapy and/or radiation therapy.

Exercise Recommendation for People With Bone Metastases: Expert Consensus for Health Care Providers and Exercise Professionals

PURPOSE

Exercise has been underutilized in people with advanced or incurable cancer despite the potential to improve physical function and reduce psychosocial morbidity, especially for people with bone metastases because of concerns over skeletal complications. The International Bone Metastases Exercise Working Group (IBMEWG) was formed to develop best practice recommendations for exercise programming for people with bone metastases on the basis of published research, clinical experience, and expert opinion.

METHODS

The IBMEWG undertook sequential steps to inform the recommendations: (1) modified Delphi survey, (2) systematic review, (3) cross-sectional survey to physicians and nurse practitioners, (4) in-person meeting of IBMEWG to review evidence from steps 1-3 to develop draft recommendations, and (5) stakeholder engagement.

RESULTS

Recommendations emerged from the contributing evidence and IBMEWG discussion for pre-exercise screening, exercise testing, exercise prescription, and monitoring of exercise response. Identification of individuals who are potentially at higher risk of exercise-related skeletal complication is a complex interplay of these factors: (1) lesion-related, (2) cancer and cancer treatment-related, and (3) the person-related. Exercise assessment and prescription requires consideration of the location and presentation of bone lesion(s) and should be delivered by qualified exercise professionals with oncology education and exercise prescription experience. Emphasis on postural alignment, controlled movement, and proper technique is essential.

CONCLUSION

Ultimately, the perceived risk of skeletal complications should be weighed against potential health benefits on the basis of consultation between the person, health care team, and exercise professionals. These recommendations provide an initial framework to improve the integration of exercise programming into clinical care for people with bone metastases.

Exercise or physical activity-related adverse events in people receiving peritoneal dialysis: A systematic review

People receiving peritoneal dialysis (PD) may benefit from participation in exercise or physical activity. However, exercise therapy for people receiving PD is not typically included in routine care, in part, due to ongoing uncertainties about risk. The aim of this review was to systematically collate and explore data on adverse events experienced by people receiving PD while undertaking an exercise or physical activity intervention. Searches yielded 25 exercise or physical activity intervention studies involving people receiving PD. Of these 25 studies, 17 studies provided adverse event data and were included in the final review. No serious adverse events (e.g. death, hospitalisation) were found attributable to the intervention. From 50 reported adverse events during the intervention period, 32 were attributable to the exercise or physical activity intervention with most being musculoskeletal (e.g. muscle/joint pain, etc.) followed by fatigue. Most events were mild to moderate in severity and resolved by exercise programme modification, education, rest or medication. The results from this review did not uncover signals of harm for people receiving PD who engage in exercise with risk of adverse events appearing to be low, however, improved adverse events reporting and further interventional studies are required before robust guidelines can be produced.

Impact of physical exercise in advanced-stage cancer patients: Systematic review and meta-analysis

Health professionals predict that the number of people who will suffer and die from oncological diseases will continue to increase. It is vitally important to provide comprehensive care to these patients and prescribe physical exercise programs as adjuvant therapy. The objective of this systematic review was to determine the impact of physical exercise on advanced‐stage cancer patients. A literature search was performed in eight different databases. This search focused on randomized controlled trials (RCTs) published during the last 10 years. To assess the methodological quality of the sample of 15 RCTs finally obtained, the PEDro scale was used. Aerobic and strength training methods were used. The combination of both aerobic and strength training methods was the most frequently reported. Likewise, different physical and psychological variables were recorded, from which improvements were seen in fatigue, independence, quality of life and sleep, among others. The participation in physical exercise programs by advanced‐stage cancer patients has a positive impact on health. Providing these programs serves as adjuvant therapy, facilitating the comprehensive care of patients. Similarly, aerobic, strength or mixed training programs increase the muscle mass of patients and therefore reduce hypotonia, the main side effect during the advanced‐stages of cancer.

Effect of acute aerobic exercise before immunotherapy and chemotherapy infusion in patients with metastatic non-small-cell lung cancer: protocol for the ERICA feasibility trial

INTRODUCTION

Patients with metastatic non-small cell lung cancer (mNSCLC) suffer from numerous symptoms linked to disease and treatment which may further impair the patient's overall condition. In addition to its benefits on quality of life and fatigue, physical exercise may improve treatment response, notably due to its known effects on the immune system. The ERICA study is designed to assess the feasibility of a supervised acute physical exercise therapy realised immediately prior immune-chemotherapy infusion in patients with mNSCLC. Secondary objectives will examine the effects of acute exercise combined with an unsupervised home-walking programme on clinical, physical, psychosocial and biological parameters.

METHODS AND ANALYSIS

ERICA is a prospective, monocentric, randomised controlled, open-label feasibility study conducted at the Centre Léon Bérard Comprehensive Cancer Center (France). Thirty patients newly diagnosed with mNSCLC will be randomised (2:1 ratio) to the 'exercise' or the 'control' group. At baseline and during the last treatment cycle, participants in both groups will receive Physical Activity recommendations, and two nutritional assessments. In the exercise group, participants will receive a 3-month programme consisting of a supervised acute physical exercise session prior to immune-chemotherapy infusion, and an unsupervised home-based walking programme with an activity tracker. The acute exercise consists of 35 min interval training at submaximal intensity scheduled to terminate 15 min prior to infusion. Clinical, physical, biological and psychosocial parameters will be assessed at baseline, 3 and 6 months after inclusion. Biological measures will include immune, inflammatory, metabolic, oxidative stress biomarkers and molecular profiling.

ETHICS AND DISSEMINATION

The study protocol was approved by the French ethics committee (Comité de protection des personnes Ile de France II, N°ID-RCB 20.09.04.65226, 8 December 2020). The study is registered on ClinicalTrials.gov (NCT number:NCT04676009) and is at the pre-results stage. All participants will sign an informed consent form. The findings will be disseminated in peer-reviewed journals and academic conferences.

Supportive Care in Oncology-From Physical Activity to Nutrition

The diagnosis and treatment of cancer are associated with impairment at the physical and at psychological level. In addition, side effects are a potentially treatment-limiting factor that may necessitate dose reduction, delay, or even discontinuation of therapy, with negative consequences for outcome and mean survival. Numerous studies have shown that physical activity and sports and exercise therapy programs are not only practicable but also recommendable for oncologic patients during the acute phase and in the aftercare. Furthermore, nutrition plays an important role in all stages of tumor therapy. A timely integration of a nutrition therapy and physical activity in the form of physiotherapy and sports therapy serves to prevent and reduce treatment-associated side effects. Evidence-based recommendations on cancer prevention through nutrition therapy, physical activity, and sports and exercise therapy should be integrated into treatment plans for oncology patients as well as in health care services for the general population. Individual counselling by trained nutrition and exercise specialists may be advisable to receive concrete recommendations on the respective tumor entity or specific side effects. This mini review is based on a selective literature search in the PubMed database and Cochrane Central Register of Controlled Trials on the subjects of healthy diet and physical activity in primary prevention and follow-up about cancer.

Community-Based Exercise Programs for Cancer Survivors: A Scoping Review of Program Characteristics Using the Consolidated Framework for Implementation Research

OBJECTIVE

To describe the characteristics of exercise programs for survivors of cancer conducted outside of a research laboratory (ie, home-based or community-based settings).

DATA SOURCES

A systematic search of published literature was conducted using Medline, Pubmed, Cumulative Index of Nursing and Allied Health Literature, PsycINFO, SPORTdiscus, and Embase from 1980 to January 2021. Where conference abstracts were identified, authors were contacted for other articles.

STUDY SELECTION

Two independent reviewers screened titles and abstracts and full texts of potentially relevant studies to determine eligibility, with discrepancies resolved by discussion. Included studies were reports of exercise programs or interventions in which participants exercise at home or in a community-based setting and including individuals diagnosed with cancer either undergoing treatment or who had completed treatment.

DATA EXTRACTION

Data were extracted using the Oxford Implementation Index and coded under the 5 domains of the Consolidated Framework for Implementation Research (CFIR). Extraction and coding were completed by 2 independent reviewers, with discrepancies resolved through discussion. Data were synthesized narratively according to CFIR.

DATA SYNTHESIS

A total of 58 publications describing 34 individual programs from around the world were included. Of these, only 14 publications had the specific goal of reporting on program implementation and development. A variety of intervention characteristics and characteristics of individuals involved in the intervention were described. Reporting of factors related to the CFIR domains of inner setting, outer setting, and implementation process were minimal.

CONCLUSIONS

This review summarizes the characteristics of existing programs that have been reported in the literature and finds that partnerships and collaboration occur in the inner and outer settings and as part of the process of implementation. This review highlights key knowledge gaps to be answered to support the development of future community-based interventions.

Results From a Physical Activity Intervention Feasibility Study With Kidney Inpatients

Background:

Individuals with end-stage kidney disease requiring dialysis are often physically inactive, resulting in reduced physical functioning, increased frailty, and reduced quality of life. Furthermore, extended hospital stays and frequent readmissions are common, exacerbating health care costs. Physical activity may improve physical functioning, disability, and frailty but is not part of standard care of patients requiring dialysis. Research is required to determine the feasibility of implementing physical function assessments and physical activity programs in kidney inpatients requiring dialysis.

Objective:

To assess the feasibility and preliminary efficacy of an early-physical activity intervention (Move More study) in the care of kidney inpatients requiring dialysis. It was hypothesized that the intervention would be feasible with regards to administration and participation, meeting a priori feasibility criteria, and that kidney inpatients would benefit from participating.

Design:

Pilot study.

Setting:

Patient Unit 37, Foothills Medical Center, Calgary, AB, Canada.

Patients:

Kidney in-patients receiving dialysis.

Measurements:

Feasibility data were collected for recruitment, participation, assessment completion, physical activity completion, and adverse events. Participant and healthcare practitioner (HCP) satisfaction with the intervention was assessed using a questionnaire. Frailty and physical function were assessed by the kinesiologist at baseline and postintervention prior to hospital discharge.

Methods:

The study was a single-arm pilot intervention examining feasibility and preliminary efficacy. Kidney inpatients requiring dialysis were recruited to an individualized in-hospital physical activity intervention for the duration of their hospital stay. The intervention was led by a kinesiologist and supported by the clinical care team, including physiotherapists and nurse clinicians. Individualized exercise programs were created for patients to perform daily during their stay. These programs focused on strength, mobility, balance, and general movement and were tailored to each patient’s needs.

Results:

Thirty-six percent of eligible patients (n = 23/64) consented to participate in the Move More study, of whom 78% (n = 18/23) completed the intervention. The a priori level for consent to participate in the intervention was set at 60%. In addition, the a priori level for completion of assessments pre and postintervention was 50%. Ninety-five percent (n = 22/23) of preintervention assessments were completed compared to 65% of postintervention assessments. All participants who completed the survey (100%, n = 14/14) and most of the staff (77%, n = 24/31) reported being satisfied or very satisfied with the program. There were no adverse events related to the intervention. On average, Move More patients demonstrated improvements in frailty status and specific subsets of quality of life.

Limitations:

Firstly, as a feasibility study, the research was not powered to address the effectiveness of the intervention and lacked a comparison group to definitively link observed changes to the intervention itself. The voluntary nature of recruitment may have been biased toward ESKD inpatients with above-average motivation and baseline function. Furthermore, the small sample size from a single site limits the generalizability of findings. An additional limitation was the fact that postassessments were missed on a large number of patients, due to them being discharged prior to research staff knowing and being able to complete the assessments. Finally, studying the length of stay across the institution, as opposed to just the individual ward, would provide insight into hospitalization impact for these patients.

Conclusions:

The administration of and participation in a physical activity intervention for kidney inpatients requiring dialysis was initially not feasible primarily due to low recruitment and adherence challenges. The study was modified by including a research team member on the unit to increase recruitment efforts and support exercise adherence. The intervention impact includes potentially benefits on frailty and quality of life.

Physical Activity Is Associated with Improved Overall Survival among Patients with Metastatic Colorectal Cancer

Simple Summary

Physical activity is linked to longer survival among non-metastasized colorectal cancer patients. It is unclear if physical activity is also beneficial for survival among patients with metastatic colorectal cancer. We researched this question in our study of 293 patients with metastatic colorectal cancer. We found that participants who reported higher levels of physical activity at diagnosis lived longer compared to patients who reported low activity levels. Furthermore, adherence to the physical activity guidelines for cancer survivors was related to prolonged survival. Our findings suggest that patients with metastatic colorectal cancer also benefit from being physically active. Future studies are needed to investigate whether improving exercise levels after diagnosis of metastasis is also beneficial and what kind of exercise interventions are most optimal for possibly improving survival time of patients with metastatic colorectal cancer.

Abstract

Regular physical activity (PA) is associated with improved overall survival (OS) in stage I–III colorectal cancer (CRC) patients. This association is less defined in patients with metastatic CRC (mCRC). We therefore conducted a study in mCRC patients participating in the Prospective Dutch Colorectal Cancer cohort. PA was assessed with the validated SQUASH questionnaire, filled-in within a maximum of 60 days after diagnosis of mCRC. PA was quantified by calculating Metabolic Equivalent Task (MET) hours per week. American College of Sports and Medicine (ACSM) PA guideline adherence, tertiles of moderate to vigorous PA (MVPA), and sport and leisure time MVPA (MVPA-SL) were assessed as well. Vital status was obtained from the municipal population registry. Cox proportional-hazards models were used to study the association between PA determinants and all-cause mortality adjusted for prognostic patient and treatment-related factors. In total, 293 mCRC patients (mean age 62.9 ± 10.6 years, 67% male) were included in the analysis. Compared to low levels, moderate and high levels of MET-hours were significantly associated with longer OS (fully adjusted hazard ratios: 0.491, (95% CI 0.299–0.807, p value = 0.005) and 0.485 (95% CI 0.303–0.778, p value = 0.003), respectively), as were high levels of MVPA (0.476 (95% CI 0.278–0.816, p value = 0.007)) and MVPA-SL (0.389 (95% CI 0.224–0.677, p value < 0.001)), and adherence to ACSM PA guidelines compared to non-adherence (0.629 (95% CI 0.412–0.961, p value = 0.032)). The present study provides evidence that higher PA levels at diagnosis of mCRC are associated with longer OS.

Adverse Events Reporting of Clinical Trials in Exercise Oncology Research (ADVANCE): Protocol for a Scoping Review

INTRODUCTION

Adequate, transparent, and consistent reporting of adverse events (AEs) in exercise oncology trials is critical to assess the safety of exercise interventions for people following a cancer diagnosis. However, there is little understanding of how AEs are reported in exercise oncology trials. Thus, we propose to conduct a scoping review to summarise and evaluate current practice of reporting of AEs in published exercise oncology trials with further exploration of factors associated with inadequate reporting of AEs. The study findings will serve to inform the need for future research on standardisation of the definition, collection, and reporting of AEs for exercise oncology research.

MATERIALS AND METHODS

The ADVANCE (ADverse eVents reporting of clinicAl trials iN exerCise oncology rEsearch) study will be conducted and reported following the PRISMA extension for scoping reviews guideline. Any type of clinical trial involving an exercise intervention in people living with and beyond cancer with a full-text report in English will be included. Six electronic databases (Embase, PubMed, Google Scholar, Web of Science Core Collection, SPORTDiscus, and CINAHL Plus) will be searched for studies. Two independent review authors will assess eligibility of identified studies, chart data using pre-established extraction forms, and evaluate adequacy of reporting of AEs-related data against a 20-item scoring checklist derived from the CONSORT (Consolidated Standards of Reporting Trials) harms extension. We will summarise results using descriptive and inferential analysis methods.

ETHICS AND DISSEMINATION

No ethics approval will be required to conduct the ADVANCE study owing to inclusion of only published data. The study results will be disseminated via publications in peer-reviewed journals and presentations at national and internationa  conferences.

Home-based, supervised, and mixed exercise intervention on functional capacity and quality of life of colorectal cancer patients: a meta-analysis

This systematic review and meta-analysis of randomized controlled trials tested the effects of home-based, supervised, or mixed exercise interventions on the functional capacity (FC) and quality of life (QoL) in colorectal cancer patients. A literature search was performed using the PubMed, Embase, Cochrane, and Medline databases. Two reviewers screened the literature through March 10, 2021 for studies related to exercise and colorectal cancer. Of the 1161 screened studies in the initial search, 13 studies met the eligibility criteria (home-based = 6 studies; supervised or mixed = 7 studies). Overall, 706 patients were enrolled in the trials, and 372 patients were submitted to home-based, supervised, or mixed exercise intervention. The overall results from the main meta-analysis showed a significant effect regarding supervised or mixed intervention (6 studies; p = 0.002; I² = 43%; PI 0.41–1.39); however, no significant effect was observed for home-based intervention (5 studies; p = 0.05; I² = 25%; PI − 0.34–0.76). A sensitivity analysis based on studies with intervention adherence ≥ 80% (home-based = 3 studies; supervised or mixed = 4 studies) revealed that home-based intervention or intervention entirely supervised or with some level of supervision (mixed) are effective in improving the QoL and FC of CRC patients. In summary, this meta-analysis verified that supervised and home-based exercise can modify QoL and FC when intervention adherence ≥ 80%. Regardless of the supervision characteristics, future RCTs are strongly encouraged to provide a detailed description of the exercise variables in physical interventions for CRC prescription. This perspective will allow a refined exercise prescription for patients with CRC, mainly according to their clinical status.

Attention to principles of exercise training: an updated systematic review of randomized controlled trials in cancers other than breast and prostate

BACKGROUND

The primary objective of this systematic review was to update our previous review on randomized controlled trials (RCTs) of exercise in cancers other than breast or prostate, evaluating: 1) the application of principles of exercise training within the exercise prescription; 2) reporting of the exercise prescription components (i.e., frequency, intensity, time, and type (FITT)); and 3) reporting of participant adherence to FITT. A secondary objective was to examine whether reporting of these interventions had improved over time.

METHODS

MEDLINE, EMBASE, CINAHL and SPORTDiscus databases were searched from 2012 to 2020. Eligible studies were RCTs of at least 4 weeks of aerobic and/or resistance exercise that reported on physiological outcomes relating to exercise (e.g., aerobic capacity, muscular strength) in people with cancer other than breast or prostate.

RESULTS

Eighty-six new studies were identified in the updated search, for a total of 107 studies included in this review. The principle of specificity was applied by 91%, progression by 32%, overload by 46%, initial values by 72%, reversibility by 7% and diminishing returns by 5%. A significant increase in the percentage of studies that appropriately reported initial values (46 to 80%, p < 0.001) and progression (15 to 37%, p = 0.039) was found for studies published after 2011 compared to older studies. All four FITT prescription components were fully reported in the methods in 58% of all studies, which was higher than the proportion that fully reported adherence to the FITT prescription components in the results (7% of studies). Reporting of the FITT exercise prescription components and FITT adherence did not improve in studies published after 2011 compared to older studies.

CONCLUSION

Full reporting of exercise prescription and adherence still needs improvement within exercise oncology RCTs. Some aspects of exercise intervention reporting have improved since 2011, including the reporting of the principles of progression and initial values. Enhancing the reporting of exercise prescriptions, particularly FITT adherence, may provide better context for interpreting study results and improve research to practice translation.

SupPoRtive Exercise Programmes for Accelerating REcovery after major ABdominal Cancer surgery trial (PREPARE-ABC): Pilot phase of a multicentre randomised controlled trial

AIM

PREPARE-ABC is a pragmatic multicentre randomised controlled trial including an internal pilot designed to assess the clinical and cost-effectiveness of pre- and postoperative exercise in relation to short- and longer-term postoperative recovery outcomes in colorectal cancer patients undergoing surgical resection. Here, we report on internal pilot phase data for the first 200 patients randomised to the trial, which included prespecified stop-go criteria used to inform the decision to progress to the fully powered trial by the funder.

METHODS

Eligible and consenting patients are randomly assigned (1:1:1) to hospital-supervised exercise, home-supported exercise or treatment as usual (TAU). Randomisation is concealed but clinical teams providing treatment and participants are unmasked. Primary outcomes are 30-day morbidity (Clavien-Dindo) and 12-month health-related quality of life (Medical Outcomes Study Health Questionnaire). Here, we present findings from the prespecified pilot phase which assessed feasibility of site set up, recruitment, adherence and acceptability of trial processes to patients and site staff.

RESULTS

Between 9 November 2016 and 18 May 2018, 18 sites were set up, with 200 patients randomised to either hospital-supervised exercise (68), home-supported exercise (69) or treatment as usual (TAU) (63). Across the groups, 19 patients did not proceed to surgery or withdrew and 52% experienced a complication. Over half of the participants (57%) in the hospital-supervised group attended ≥6 preoperative sessions and 50% attended ≥5 monthly postoperative exercise "booster sessions". In the home-supported group, 70% patients engaged with ≥2 telephone support sessions in the preoperative phase and 80% engaged in ≥5 monthly telephone support "booster sessions". Adverse events were reported by 22 patients and three patients reported a serious adverse event. The majority of complications were Clavien-Dindo grades 1-2; however, 16 patients experienced one or more Clavien-Dindo grade 3-4 complication(s).

CONCLUSIONS

Results of the internal pilot phase confirm the feasibility of site set-up and patient recruitment, representativeness of the sample population and adequate adherence to hospital-supervised and home-supported exercise. On the basis of these positive results, progression to the fully-powered trial was authorised by the funder.

A scoping review of studies exploring leisure-time physical activity in adults diagnosed with advanced cancer

OBJECTIVES

Despite improving survival rates, people with advanced cancer face several physical and psychosocial concerns. Leisure-time physical activity (LPA) has been found to be beneficial after cancer diagnosis, but little is known about the current state of research exploring LPA in advanced cancer. Our objectives were to (a) map the literature examining LPA in people with advanced cancer, (b) report on the terms used to describe the advanced cancer population within the literature, and (c) examine how the concept of LPA is operationalized within the literature.

METHOD

Our scoping review followed Arksey and O'Malley's methodological framework. We performed a search of 11 electronic databases and supplementary sources (February 2018; database search updated January 2020). Two reviewers independently reviewed and selected articles according to the inclusion criteria: English-language journal articles on original primary research studies exploring LPA in adults diagnosed with advanced cancer. Descriptive and thematic analyses were performed.

RESULTS

Ninety-two articles met our criteria. Most included studies were published in the last decade (80%) and used quantitative methods (77%). Many study populations included mixed (40%), breast (21%), or lung (17%) cancers. Stages 3-4 or metastatic disease were frequently indicated to describe study populations (77%). Several studies (68%) described LPA programs or interventions. Of these, 78% involved structured aerobic/resistance exercise, while 16% explored other LPA types.

SIGNIFICANCE OF RESULTS

This review demonstrates a recent surge in research exploring LPA in advanced cancer, particularly studies examining exercise interventions with traditional quantitative methods. There remains insufficient knowledge about patient experiences and perceptions toward LPA. Moreover, little is known about other leisure activities (e.g., Tai Chi, dance, and sports) for this population. To optimize the benefits of LPA in people with advanced cancer, research is needed to address the gaps in the current literature and to develop personalized, evidence-based supportive care strategies in cancer care.

Estrogen-Receptor-Positive Breast Cancer in Postmenopausal Women: The Role of Body Composition and Physical Exercise

Breast cancer (BC) is the most commonly diagnosed cancer among women worldwide and the most common cause of cancer-related death. To date, it is still a challenge to estimate the magnitude of the clinical impact of physical activity (PA) on those parameters producing significative changes in future BC risk and disease progression. However, studies conducted in recent years highlight the role of PA not only as a protective factor for the development of ER+ breast cancer but, more generally, as a useful tool in the management of BC treatment as an adjuvant to traditional therapies. In this review, we focused our attention on data obtained from human studies analyzing, at each level of disease prevention (i.e., primary, secondary, tertiary and quaternary), the positive impact of PA/exercise in ER+ BC, a subtype representing approximately 70% of all BC diagnoses. Moreover, given the importance of estrogen receptors and body composition (i.e., adipose tissue) in this subtype of BC, an overview of their role will also be made throughout this review.

Connected device and therapeutic patient education to promote physical activity among women with localised breast cancer (DISCO trial): protocol for a multicentre 2×2 factorial randomised controlled trial

INTRODUCTION

Despite safety and benefits of physical activity during treatment of localised breast cancer, successful exercise strategies remain to be determined. The primary objective of the 'dispositif connecté', that is, connected device in English trial is to evaluate the efficacy of two 6-month exercise interventions, either single or combined, concomitant to adjuvant treatments, on the physical activity level of patients with breast cancer, compared with usual care: an exercise programme using a connected device (activity tracker, smartphone application, website) and a therapeutic patient education intervention. Secondary objectives are to evaluate adherence to interventions, their impact at 6 and 12 months, representations and acceptability of interventions, and to assess the cost-effectiveness of the interventions using quality-adjusted life-years.

METHODS AND ANALYSIS

This is a 2×2 factorial, multicentre, phase III randomised controlled trial. The study population (with written informed consent) will consist of 432 women diagnosed with primary localised invasive breast carcinoma and eligible for adjuvant chemotherapy, hormonotherapy and/or radiotherapy. They will be randomly allocated between one of four arms: (1) web-based connected device (evolving target number of daily steps and an individualised, semisupervised, adaptive programme of two walking and one muscle strengthening sessions per week in autonomy), (2) therapeutic patient education (one educational diagnosis, two collective educational sessions, one evaluation), (3) combination of both interventions and (4) control. All participants will receive the international physical activity recommendations. Assessments (baseline, 6 and 12 months) will include physical fitness tests, anthropometrics measures, body composition (CT scan, bioelectrical impedance), self-administered questionnaires (physical activity profile (Recent Physical Activity Questionnaire), quality of life (European Organization for Research and Treatment of Cancer Quality-Of-Life Questionnaire-30, EQ-5D-5L), fatigue (Piper Fatigue Scale-12), social deprivation (Evaluation of Deprivation and Inequalities in Health Examination Centres), lifestyle, physical activity barriers, occupational status) and biological parameters (blood draw).

ETHICS AND DISSEMINATION

This study was reviewed and approved by the French Ethics Committee. The findings will be disseminated to the scientific and medical community via publications in peer-reviewed journals and conference presentations.

Cancer Cachexia: Its Mechanism and Clinical Significance

The term "cachexia" is derived from the Greek words kakos (bad) and hexis (habit). Cachexia is a malnutrition associated with chronic diseases such as cancer, chronic heart failure, chronic renal failure, and autoimmune diseases, and is characterized by decreased skeletal muscle mass. Cancer cachexia is quite common in patients with advanced cancer. Weight loss is also a characteristic symptom of cancer cachexia, along with decreased skeletal muscle mass. As nutritional supplementation alone cannot improve cachexia, cytokines and tumor-derived substances have been attracting attention as its relevant factors. Cancer cachexia can be also associated with reduced chemotherapeutic effects, increased side effects and treatment interruptions, and even poorer survival. In 2011, a consensus definition of cachexia has been proposed, and the number of relevant research reports has increased significantly. However, the pathogenesis of cachexia is not fully understood, and there are currently few regulatory-approved standard treatments for cachexia. The main reason for this is that multiple etiologies are involved in the development of cachexia. In this review, we will outline the current status of cachexia, the mechanisms of which have been elucidated in recent years, especially from the perspective of advanced cancer.

A multimodal approach to cancer-related cachexia: from theory to practice

Introduction: Cachexia represents a relevant issue in oncological care, which is still lacking effective therapies. Although the incidence of cancer cachexia varies across cancer types, it is responsible for approximately a quarter of cancer-related deaths. The pathophysiology of this syndrome is multifactorial, including weight loss, muscle atrophy and impairment of the pro-/anti-inflammatory balance.Areas covered: Diagnostic criteria and optimal endpoints for cachexia-dedicated trials are still debated, slowing the identification of interventions counteracting cachexia sequaele. The multifaceted features of this syndrome support the rationale for personalized therapy. A multimodal approach is likely to offer the best option to address key cachexia-related issues. Pharmacologic agents, physical exercise, nutritional and psycho-social interventions may have a synergistic effect, and improve quality of life.Expert opinion: A personalized multimodal intervention could be the best strategy to effectively manage cancer cachexia. To offer such a comprehensive approach, a specialized staff, including health professionals with different expertise, is necessary. Each specialist plays a specific role inside the multimodal intervention, with the aim of delivering the best cancer care and access to the most effective therapeutic options for each patient.

Effect of Exercise Interventions on Quality of Life in Patients With Lung Cancer: A Systematic Review of Randomized Controlled Trials

PROBLEM IDENTIFICATION

Improving quality of life (QOL) is a key issue for patients with lung cancer. Exercise interventions could positively affect patients' QOL; however, there is no clear-cut understanding of the role of exercise in improving QOL in patients with lung cancer.

LITERATURE SEARCH

The PubMed®, Embase®, Cochrane Library, and Web of Science electronic databases were searched from inception to September 6, 2019.

DATA EVALUATION

16 randomized controlled trials met the inclusion criteria. A qualitative synthesis method was used to identify the effect of exercise interventions on QOL in patients with lung cancer.

SYNTHESIS

This review indicates that exercise interventions may have beneficial effects on the QOL of patients with lung cancer. The effectiveness seems to be affected by the duration of the intervention, as well as exercise frequency, intensity, and adherence.

IMPLICATIONS FOR PRACTICE

Exercise interventions can be integrated into management plans for patients with lung cancer to improve their QOL. Healthcare providers should consider developing optimal exercise prescriptions to maximize the results for this population.

Bridging the gap: a pre-post feasibility study of embedding exercise therapy into a co-located cancer unit

PURPOSE

To establish the feasibility of embedding a flexible, exercise-based rehabilitation program into a cancer treatment unit to allow cancer survivors early exercise support.

METHOD

A pre-post study was conducted using Bowen's Framework to describe key domains of feasibility: demand (referrals), acceptability (uptake, attendance, satisfaction), implementation (resources), practicality (adverse events, costs) and limited-efficacy (function, quality of life, self-efficacy). Participants were medically stable, adult cancer survivors receiving curative or palliative treatment for cancer at the health service. Participants completed an 8-week home or hospital-based exercise program. Data were analysed descriptively. Standardised mean differences (Hedge's g) and mean differences were calculated to determine effect size and clinical significance.

RESULTS

The exercise-based rehabilitation service received 155 referrals over 6 months. Of those eligible, 73/119 (61%) commenced. Participants opting for twice-weekly, hospital-based exercise attended 9/16 (56%) sessions. Participants reported high satisfaction and there were no major adverse events. The program utilised existing resources, with the predominant cost being staff. The average health service cost per participant was AUD $1,104. Participants made clinically significant gains in function (6-min walk distance; + 73 m, 95% confidence interval 49 to 96) and quality of life (EORTC QLQ-C30 Global quality of life; + 8 units, 95% confidence interval 3 to 13).

CONCLUSION

Implementation of exercise-based rehabilitation in a co-located cancer unit was safe and feasible. Access, patient and staff education and establishing funding streams are important implementation considerations. Implications for cancer survivors Access to exercise in a cancer unit provides opportunity for early intervention to optimise function during treatment.

Longitudinal changes in skeletal muscle mass in patients with advanced squamous cell lung cancer

Background

Skeletal muscle depletion (sarcopenia) is associated with poor prognosis in patients with lung cancer. We analyzed changes in skeletal muscle area using serial computed tomography (CT) until the death of patients with advanced squamous cell lung cancer (SQCLC).

Methods

This retrospective study comprised 70 consecutive patients who underwent palliative chemotherapy for SQCLC. The cross‐sectional area of the skeletal muscle at the level of the first lumbar vertebra (L1) was measured using chest CT. An artificial intelligence algorithm was developed and used for the serial assessment of the muscle area. Sarcopenia was defined as an L1 skeletal muscle index <46 cm²/m² in men and < 29 cm²/m² in women.

Results

The median age was 69 years; 62 patients (89%) had metastatic disease at the time of initial diagnosis. Sarcopenia was present in 58 patients (82.9%) at baseline; all patients experienced net muscle loss over the disease trajectory. The median overall survival was 8.7 (95% confidence interval 5.9–11.5) months. The mean percentage loss of skeletal muscle between the first and last CT was 16.5 ± 11.0%. Skeletal muscle loss accelerated over time and was the highest in the last 3 months of life (p < 0.001). Patients losing skeletal muscle rapidly (upper tertile, >3.24 cm²/month) had shorter overall survival than patients losing skeletal muscle slowly (median, 5.7 vs. 12.0 months, p < 0.001).

Conclusions

Patients with advanced SQCLC lose a significant amount of skeletal muscle until death. The rate of muscle area reduction is faster at the end of life.

Patients with advanced SQCLC lose a significant amount of skeletal muscle until death. The rate of muscle area reduction is faster at the end of life.

Exercise Medicine in the Management of Pancreatic Cancer: A Systematic Review

ABSTRACT

The aim of this study was to examine the health-related effects of exercise in patients with pancreatic cancer (PanCa) through a systematic review of current evidence. Studies were obtained through searching PubMed, Web of Science, PsycINFO, Embase, CINAHL Plus, and Cochrane Library databases with additional hand searches. All intervention-based studies were included if it involved (1) adult patients with PanCa, (2) exercise training, and (3) findings in quality of life, cancer-related fatigue, psychological distress, and physical function. The review protocol was registered in PROSPERO: CRD42020154684. Seven trials described in 9 publications were included consisting of 201 patients with early-stage and advanced PanCa. Participants were required to perform supervised and/or home-based, low- to moderate-intensity resistance and/or aerobic exercise for 12 to 35 weeks or duration of neoadjuvant therapy. There were no exercise-related adverse events with a reported retention rate of 71% to 90% and exercise attendance of 64% to 96%. The programs were consistently associated with improvements in cancer-related fatigue, psychological distress, and physical function, with mixed effects on quality of life. Exercise training seems to be safe and feasible and may have a beneficial effect on various physical and psychological outcomes in patients with PanCa. Further work with rigorous study designs is required to consolidate and advance current findings.

The Use of Theory to Develop Physical Activity Interventions in Urological Cancer Survivors: A Narrative Review

OBJECTIVES

To summarize the current available evidence on the use of behavior change theories to explain and change physical activity behavior in urological cancer survivors.

DATA SOURCES

Five electronic databases including Medline, Web of Science, Embase, Cochrane, and Psych INFO and reference lists of key studies were searched between database inception and November 2020. Peer-reviewed articles on the use of behavior change theories to understand or change physical activity in urological cancer survivors were included.

CONCLUSION

The theory of planned behavior and the social cognitive theory were the most used theories to explain and change physical activity behavior in urological cancers, respectively. However, the use of behavior change theories in physical activity interventions for urological cancers is still low across all urological tumor groups. Planning frameworks such as the intervention mapping approach should be used to enhance the systematic use of behavior change theories during every phase of intervention development. In addition, more research is needed to identity which behavior change techniques are most effective to change physical activity behavior in urological cancer survivors.

IMPLICATIONS FOR NURSING PRACTICE

Nurses play a key role in the urological cancer patients' clinical pathway and should be able to motivate patients to engage in sufficient physical activity levels. Therefore, it is important that nurses understand the underlying reasons why patients (do not) engage in physical activity and which behavior change techniques are most effective in changing a patients' behavior.

Adverse Events During Supervised Exercise Interventions in Pediatric Oncology-A Nationwide Survey

Objectives: Exercise interventions during and after treatment for pediatric cancer are associated with beneficial physical, psychological, and social effects. However, valid data about adverse events (AEs) of such interventions have rarely been evaluated. This retrospective study evaluates AEs that occurred during supervised oncological exercise programs for pediatric cancer patients and survivors. Methods: This Germany-wide study used a self-administered online survey focusing on general program characteristics and AEs retrospectively for 2019. The questionnaire included (a) basic data on the offered exercise program, (b) AEs with consequences (Grade 2-5) that occurred in 2019 during an exercise intervention, (c) number of Grade 1 AEs, (d) safety procedures as part of the exercise programs, and (e) possibility to give feedback and describe experience with AEs in free text. Results: Out of 26 eligible exercise programs, response rate of program leaders was 92.3% (n = 24). Representatives working for Universities (n = 6), rehabilitation clinics (n = 3), acute cancer clinics (n = 12), and activity camps (n = 3) participated. In total, 35,110 exercise interventions with varying duration were recorded for 2019. Six AEs with consequences (Grade 2-3) occurred during exercise interventions after cancer treatment resulting in an incidence of 17 per 100,000 exercise interventions (0.017%). No life-threatening consequences or death were reported and no serious AE occurred during acute cancer treatment. Grade 1 AE occurred with a frequency of 983, corresponding to an incidence of 2,800 per 100,000 interventions (2.8%). Most frequent Grade 1 AE were muscle soreness, circulatory problems, and abdominal pain. The most frequent preventive safety procedures at the institutions were regular breaks, consultations with the medical treatment team, and material selection with low injury potential. Conclusions: Supervised exercise interventions for pediatric cancer patients and survivors seem to be safe and AEs with consequences comparatively rare when compared to general childhood population data. Occurrence of grade 1 AEs was common, however, causality was probably not evident between AEs and the exercise intervention. Future research should standardize assessment of AEs in clinical practice and research, and prospectively register and evaluate AEs that occur in the context of exercise interventions in pediatric cancer patients and survivors.
