Exploring the Impact of Exercise-Derived Extracellular Vesicles in Cancer Biology

Cancer remains a major challenge in medicine, prompting exploration of innovative therapies. Recent studies suggest that exercise-derived extracellular vesicles (EVs) may offer potential anti-cancer benefits. These small, membrane-bound particles, including exosomes, carry bioactive molecules such as proteins and RNA that mediate intercellular communication. Exercise has been shown to increase EV secretion, influencing physiological processes like tissue repair, inflammation, and metabolism. Notably, preclinical studies have demonstrated that exercise-derived EVs can inhibit tumor growth, reduce metastasis, and enhance treatment response. For instance, in a study using animal models, exercise-derived EVs were shown to suppress tumor proliferation in breast and colon cancers. Another study reported that these EVs reduced metastatic potential by decreasing the migration and invasion of cancer cells. Additionally, exercise-induced EVs have been found to enhance the effectiveness of chemotherapy by sensitizing tumor cells to treatment. This review highlights the emerging role of exercise-derived circulating biomolecules, particularly EVs, in cancer biology. It discusses the mechanisms through which EVs impact cancer progression, the challenges in translating preclinical findings to clinical practice, and future research directions. Although research in this area is still limited, current findings suggest that EVs could play a crucial role in spreading molecules that promote better health in cancer patients. Understanding these EV profiles could lead to future therapies, such as exercise mimetics or targeted drugs, to treat cancer.

Exercise-augmented THSD7B exhibited a positive prognostic implication and tumor-suppressed functionality in pan-cancer

Background

Breast cancer, one of the most prevalent malignancies among women worldwide, has rising incidence rates. Physical activity, particularly exercise, has emerged as a significant modifier of cancer prognosis, influencing both tumor biology and patient outcomes.

Methods

In this study, we utilized a murine breast cancer model, dividing mice into a control group and an exercise group; the latter underwent 21 days of voluntary running. We conducted RNA sequencing, bioinformatics analysis, pan-cancer analysis, and cellular experiments to investigate the underlying mechanisms influenced by exercise.

Results

Exercise led to a significant reduction in tumor size and weight. Post-exercise mRNA sequencing indicated a notable upregulation of THSD7B in the exercised mice, with significant alterations observed in pathways such as MicroRNAs in cancers and the Calcium signaling pathway. In a broader cancer context, THSD7B showed considerable expression variability, being significantly downregulated in several cancers, correlating with positive prognostic outcomes in PRAD, LAML, KIRC, and GBM and highlighting its potential role as a prognostic marker and therapeutic target. THSD7B expression was also negatively associated with processes of breast cancer cell proliferation, migration, and invasion.

Conclusion

This study underscores the dual role of exercise in modulating gene expression relevant to tumor growth and highlights the potential of THSD7B as a therapeutic target in cancer. Future research should further explore the specific mechanisms by which exercise and THSD7B influence cancer progression and develop immunotherapy-enhanced strategies to change patient outcomes in clinical settings.

The safety, feasibility, and efficacy of an 18-week exercise intervention for adults with primary brain cancer - the BRACE study

PURPOSE

To determine the safety, feasibility, and potential effect of an 18-week exercise intervention for adults with primary brain cancer.

MATERIALS AND METHODS

Eligible patients were 12-26-weeks post-radiotherapy for brain cancer. The individually-prescribed weekly exercise was ≥150-minutes of moderate-intensity exercise, including two resistance-training sessions. The intervention was deemed "safe" if exercise-related, serious adverse events (SAE) were experienced by <10% of participants, and feasible if recruitment, retention, and adherence rates were ≥75%, and ≥75% compliance rates were achieved in ≥75% of weeks. Patient-reported and objectively-measured outcomes were assessed at baseline, mid-intervention, end-intervention, and 6-month follow-up, using generalized estimating equations.

RESULTS

Twelve participants enrolled (51 ± 19.5 years, 5 females). There were no exercise-related SAEs. The intervention was feasible (recruitment:80%, retention:92%, adherence:83%). Participants completed a median of 172.8 (min:77.5, max:560.8) minutes of physical activity per week. 17% met the compliance outcome threshold for ≥75% of the intervention. Improvements in quality of life (mean change (95% CI): 7.9 units (1.9, 13.8)), functional well-being (4.3 units (1.4, 7.2)), depression (-2.0 units (-3.8, -0.2)), activity (112.8 min (42.1, 183.4)), fitness (56.4 meters (20.4, 92.5)), balance (4.9 s (0.9, 9.0)), and lower-body strength (15.2 kg (9.3, 21.1)) were observed end-intervention.

CONCLUSION

Preliminary evidence support that exercise is safe and beneficial to the quality of life and functional outcomes for people with brain cancer.Registration: ACTRN12617001577303.

Development of an interpretable machine learning-based intelligent system of exercise prescription for cardio-oncology preventive care: A study protocol

Background

Cardiovascular disease (CVD) and cancer are the first and second causes of death in over 130 countries across the world. They are also among the top three causes in almost 180 countries worldwide. Cardiovascular complications are often noticed in cancer patients, with nearly 20% exhibiting cardiovascular comorbidities. Physical exercise may be helpful for cancer survivors and people living with cancer (PLWC), as it prevents relapses, CVD, and cardiotoxicity. Therefore, it is beneficial to recommend exercise as part of cardio-oncology preventive care.

Objective

With the progress of deep learning algorithms and the improvement of big data processing techniques, artificial intelligence (AI) has gradually become popular in the fields of medicine and healthcare. In the context of the shortage of medical resources in China, it is of great significance to adopt AI and machine learning methods for prescription recommendations. This study aims to develop an interpretable machine learning-based intelligent system of exercise prescription for cardio-oncology preventive care, and this paper presents the study protocol.

Methods

This will be a retrospective machine learning modeling cohort study with interventional methods (i.e., exercise prescription). We will recruit PLWC participants at baseline (from 1 January 2025 to 31 December 2026) and follow up over several years (from 1 January 2027 to 31 December 2028). Specifically, participants will be eligible if they are (1) PLWC in Stage I or cancer survivors from Stage I; (2) aged between 18 and 55 years; (3) interested in physical exercise for rehabilitation; (4) willing to wear smart sensors/watches; (5) assessed by doctors as suitable for exercise interventions. At baseline, clinical exercise physiologist certificated by the joint training program (from 1 January 2023 to 31 December 2024) of American College of Sports Medicine and Chinese Association of Sports Medicine will recommend exercise prescription to each participant. During the follow-up, effective exercise prescription will be determined by assessing the CVD status of the participants.

Expected outcomes

This study aims to develop not only an interpretable machine learning model to recommend exercise prescription but also an intelligent system of exercise prescription for precision cardio-oncology preventive care.

Ethics

This study is approved by Human Experimental Ethics Inspection of Guangzhou Sport University.

How do practitioners prescribe exercise to patients with breast cancer? Professional perspectives on the key considerations for aerobic exercise in patients with breast cancer undergoing chemotherapy

OBJECTIVES

This study aimed to understand the key factors experienced accredited exercise physiologists (AEPs) and medical professionals consider when prescribing/recommending aerobic exercise to patients with breast cancer undergoing chemotherapy.

DESIGN

Modified Delphi Survey.

METHODS

A four-round, two-phase survey was conducted. Following a Delphi approach, four cancer-specific AEPs, four oncologists, and one breast cancer surgeon (median 13-yr breast-cancer-specific experience) completed phase one. Eighty-four AEPs (median 5-yr experience) completed phase two. Phase one participants answered open- and close-ended questions regarding key considerations for aerobic exercise in patients with breast cancer undergoing chemotherapy, and what information should be collected to guide exercise prescription. All questions and considerations agreed upon in phase one (>70 % rating 7-9 on a 0-9 Likert Scale) were rated by AEPs in phase two.

RESULTS

Key considerations for exercise assessment and prescription aligned closely with exercise guidelines for cancer survivors. Common strategies for exercise individualisation were identified by AEPs, including separating aerobic exercise into 5-to--9-minute bouts when required and avoiding exercising to complete exhaustion. Exercise intensity and duration should be adjusted throughout chemotherapy to improve tolerance and adherence. Novel considerations for subjective questioning and objective assessments to tailor exercise prescription were outlined.

CONCLUSIONS

This study identifies how professionals approach exercise assessment and prescription in patients with breast cancer undergoing chemotherapy. Findings can guide AEPs in practice when prescribing tailored exercise to breast cancer patients undergoing chemotherapy and inform future guidelines.

Mechanisms of exercise in the treatment of lung cancer - a mini-review

Lung cancer constitutes a formidable menace to global health and well-being, as its incidence and mortality rate escalate at an alarming pace. In recent years, research has indicated that exercise has potential roles in both the prevention and treatment of lung cancer. However, the exact mechanism of the coordinating effect of exercise on lung cancer treatment is unclear, limiting the use of exercise in clinical practice. The purpose of this review is to explore the mechanisms through which exercise exerts its anticancer effects against lung cancer. This review will analyze the biological basis of exercise's anticancer effects on lung cancer, with a focus on aspects such as the tumor microenvironment, matrix regulation, apoptosis and angiogenesis. Finally, we will discuss future research directions and potential clinical applications.

Physical Activity Levels in People with Cancer Undergoing Chemotherapy: A Systematic Review

OBJECTIVES

Physical activity (PA) has been shown to improve chemotherapy side effects, survival rates and treatment adherence in people with cancer. This review aimed to identify whether people undergoing chemotherapy in different exercise interventions meet PA guidelines during chemotherapy.

DATA SOURCES

Databases searched were CINAHL complete, PubMed, Cochrane Library, EMBASE, AMED, Joanna Briggs Institute, OVID MEDLINE, and Google Scholar. Eligibility and risk-of-bias were reviewed by two authors. PROSPERO registration: CRD42018093839.

CONCLUSION

Thirty-three studies were eligible (14 randomized controlled trials, six pre-post, and 13 cross-sectional studies), which included 2,722 people with cancer undergoing chemotherapy. Studies (n = 11/13) found PA interventions successfully increased or maintained PA participation levels, whereas PA declined without intervention. This review has identified that due to limited evidence it is not possible to determine the most appropriate intervention to improve PA for people undergoing chemotherapy. Despite the well-documented benefits of PA, most people undergoing chemotherapy do not achieve the PA guidelines. Clinicians should be aware that during treatment, participants may not meet PA guidelines even if they participate in an intervention. However, interventions may prevent PA levels from declining. Further research is required to determine the most effective approaches to increase PA levels while undergoing chemotherapy.

IMPLICATIONS FOR NURSING PRACTICE

Nurses are well placed to have conversations with patients undergoing chemotherapy regarding PA levels. PA should be considered as part of a treatment regimen. Tailored advice must be provided aiming to improve health outcomes. Referral to an exercise professional is best practice to improve the uptake of PA.

Effects and Moderators of Exercise Medicine on Cardiometabolic Outcomes in Men With Prostate Cancer Previously or Currently Undergoing Androgen Deprivation Therapy: An Individual Patient Data Meta-analysis

PURPOSE

To examine the effects and moderators of exercise effects on cardiometabolic outcomes in men with prostate cancer previously or currently undergoing androgen deprivation therapy (ADT).

RESULTS

Seven trials including 560 patients were examined. Exercise resulted in significant effects on whole-body and regional fat mass (P≤0.001). For whole-body fat mass, significant exercise effects were observed in patients who were unmarried (-1.4kg, P<0.05) and who presented with higher fat mass levels (-1.0kg, P<0.05). For diastolic blood pressure and low-density lipoprotein (LDL), younger (-4.7mmHg, P<0.05) and older patients (-0.2mmol.l^-1, P<0.10) achieved greater effects, respectively. Regarding high-density lipoprotein (HDL), patients undertaking ADT + prostatectomy + radiotherapy derived significant exercise effects (0.3mmol.l^-1, P<0.05).

CONCLUSIONS

Exercise effectively reduces fat mass across subgroups of men undergoing or following ADT with different characteristics. For diastolic blood pressure, HDL and LDL, groups based on age and treatment history could be specifically targeted with exercise medicine.

Creatine Supplementation Potentiates Exercise Protective Effects against Doxorubicin-Induced Hepatotoxicity in Mice

We tested the hypothesis that creatine supplementation may potentiate exercise’s protective effects against doxorubicin-induced hepatotoxicity. Thirty-eight Swiss mice were randomly allocated into five groups: control (C, n = 7), exercised (Ex, n = 7), treated with doxorubicin (Dox, n = 8), treated with doxorubicin and exercised (DoxEx, n = 8), and treated with doxorubicin, exercised, and supplemented with creatine (DoxExCr, n = 8). Doxorubicin was administered weekly (i.p.) for a total dose of 12 mg/kg. Creatine supplementation (2% added to the diet) and strength training (climbing stairs, 3 times a week) were performed for a total of 5 weeks. The results demonstrated that doxorubicin caused hepatotoxicity, which was evidenced by increased (p < 0.05) hepatic markers of inflammation (i.e., TNF-α and IL-6) and oxidative damage, while the redox status (GSH/GSSG) was reduced. The plasma concentrations of liver transaminases were also significantly (p < 0.05) elevated. Furthermore, doxorubicin-treated animals presented hepatic fibrosis and histopathological alterations such as cellular degeneration and the infiltration of interstitial inflammatory cells. Exercise alone partly prevented doxorubicin-induced hepatotoxicity; thus, when combined with creatine supplementation, exercise was able to attenuate inflammation and oxidative stress, morphological alterations, and fibrosis. In conclusion, creatine supplementation potentiates the protective effects of exercise against doxorubicin-induced hepatotoxicity in mice.

Cardiovascular Side Effects of Anthracyclines and HER2 Inhibitors among Patients with Breast Cancer: A Multidisciplinary Stepwise Approach for Prevention, Early Detection, and Treatment

Cardiovascular (CV) diseases (CVD) are a major cause of long-term morbidity and mortality affecting life expectancy amongst cancer survivors. In recent years, because of the possibility of early diagnosis and the increased efficacy of neo-adjuvant and adjuvant systemic treatments (targeting specific molecular pathways), the high percentage of survival from breast cancer led CVD to become the first cause of death among survivors. Therefore, it is mandatory to adopt cardioprotective strategies to minimize CV side effects and CVD in general in breast cancer patients. Cancer therapeutics-related cardiac dysfunction (CTRCD) is a common group of side effects of chemotherapeutics widely employed in breast cancer (e.g., anthracycline and human epidermal growth factor receptor 2 inhibitors). The aim of the present manuscript is to propose a pragmatic multidisciplinary stepwise approach for prevention, early detection, and treatment of cardiotoxicity in patients with breast cancer.

The Cost-Effectiveness of Adjunctive Lifestyle Interventions for the Management of Cancer: A Systematic Review

OBJECTIVE

There is a paucity of papers synthesizing the cost-effectiveness (CE) of lifestyle interventions to support cancer patients, and the synthesis papers available have used analytic methods that do not permit easy comparison between studies. We therefore evaluated the CE of adjunctive lifestyle interventions compared with usual care.

METHODS

A systematic literature search of Scopus, MEDLINE, EMBASE, PsycINFO, CINAHL and the Cochrane Library databases was conducted from database inception until June 2021. Eligible studies were economic evaluations from randomised controlled trials or modelled economic evaluations that recruited subjects with a confirmed diagnosis of cancer and were allocated to a lifestyle intervention as an adjunct or supportive treatment, or usual care. Studies were excluded if there was no cost-effectiveness analysis or if costs were identified but not related back to measures of effectiveness. CE of the included interventions was recalculated, adjusting for key differences (with respect to absolute resource costs and timing) between the broad range of study settings and a common 'target' setting. All CE data were converted into incremental net monetary benefit using a common cost-effectiveness threshold to facilitate comparison. The quality of the studies was evaluated for risk of bias using the ECOBIAS check list.

RESULTS

Nine studies were included in our review. Seven studies investigated the benefits of physical exercise in combination with cancer treatment and two studies investigated the combination of exercise and psychosocial counselling alongside cancer treatment. Six studies with an exercise intervention reported larger quality-adjusted life year (QALY) gains compared with usual care and when cost per QALY gained was considered, three of the interventions were cost effective. One of the two interventions combining exercise with psychosocial counselling was cost effective. All studies were considered of good quality but all had some limitations.

CONCLUSIONS

The evidence to support the cost effectiveness of lifestyle interventions in patients with cancer is mixed with four of the nine interventions found to be cost effective and two remaining cost effective when uncertainty was taken into account. Sensitivity analysis showed the influence of the CE threshold on the results, highlighting the importance of selecting a CE threshold that is appropriate to the setting.

Prescribing Exercise to Cancer Patients Suffering from Increased Bone Fracture Risk Due to Metastatic Bone Disease or Multiple Myeloma in Austria-An Inter- and Multidisciplinary Evaluation Measure

INTRODUCTION

In the current absence of specific functional fracture risk assessment technology, the planning of physical exercise interventions for cancer patients suffering from increased bone fracture risk remains a serious clinical challenge. Until a reliable, solely technical solution is available for the clinician, fracture risk assessment remains an inter- and multidisciplinary decision to be made by various medical experts. The aim of this short paper is depicting how this challenge should be approached in the clinical reality according to Austrian experts in cancer rehabilitation, presenting the best-practice model in Austria. Following referral from the specialist responsible for the primary cancer treatment (oncologist, surgeon, etc.), the physiatrist takes on the role of rehabilitation case manager for each individual patient. Fracture risk assessment is then undertaken by specialists in radiology, orthopedics, oncology, and radiation therapy, with the result that the affected bone regions are classified as being at highly/slightly/not increased fracture risk. Following internal clearance, exercise planning is undertaken by a specialist in exercise therapy together with the physiatrist based on the individual's fracture risk assessment. In the case in which the patient shows exercise limitations due to additional musculoskeletal impairments, adjuvant physical modalities such as physiotherapy should be prescribed to increase exercisability.

CONCLUSION

Exercise prescription for cancer patients suffering from increased fracture risk is an inter- and multidisciplinary team decision for each individual patient.

Re-visiting the resource curse hypothesis in the MINT economies

Natural resources are extremely important to the economy, particularly in emerging nations such as the MINT (Mexico, Indonesia, Nigeria, and Turkey) nations. To improve their economic performance, such nations put a priority on maximizing the use of natural resources. These natural materials are the basis on which all living creatures rely, and they are the primary motivation behind contemporary production. Therefore, the current research utilizes a dataset spanning the period from 1970 to 2019 to assess the effect of natural resource on economic growth for the MINT nations. The present study uses a unique quantile-on-quantile regression (QQR) approach to assess this interrelationship. Furthermore, we apply the novel quantile causality suggested by Troster (2018), which identifies causality across quantiles. The findings from the QQR reveal that in the majority of the quantiles, the effect of natural resources on economic expansion is positive in Nigeria and Mexico, while it is negative in Indonesia and Turkey. In addition, a feedback causality is found between economic growth and natural resources for Mexico, Indonesia, and Nigeria. Based on the results, it is paramount for policymakers to develop policies or frameworks that promote cleaner energy sources and more effective use of natural resources, which can aid the country's economic growth.

The effects of home-based exercise therapy for breast cancer-related fatigue induced by radical radiotherapy

BACKGROUND

Radiotherapy (RT) can lead to cancer-related fatigue (CRF) and decreased health-related quality of life (HRQoL) in breast cancer patients. The purpose of this trial was to examine the feasibility and efficacy of a home-based resistance and aerobic exercise intervention for reducing CRF and improving HRQoL in breast cancer patients during RT.

METHODS

Women with breast cancer (N = 106) commencing RT were randomized to 12 weeks of home-based resistance and aerobic exercise (EX) or usual care/control (CON). The primary endpoint was CRF, with secondary endpoints of HRQoL, sleep duration and quality, and physical activity. Measurements were undertaken prior to RT, at completion of RT (~ 6 weeks), at completion of the intervention (12 weeks), and 6 and 12 months after RT completion, while CRF was also measured weekly during RT.

RESULTS

Eighty-nine women completed the study (EX = 43, CON = 46). Over the 12-week intervention, EX completed 1-2 resistance training sessions and accumulated 30-40 min of aerobic exercise weekly. For CRF, EX had a quicker recovery both during and post-RT compared to CON (p < 0.05). Moreover, there was a significant difference in HRQoL between groups at RT completion, with HRQoL unchanged in CON and higher in EX (p < 0.05). There was no change in sleep duration or quality for either group and there were no exercise-related adverse effects.

CONCLUSIONS

Home-based resistance and aerobic exercise during RT is safe, feasible, and effective in accelerating CRF recovery and improving HRQoL. Improvements in CRF and HRQoL for these patients can be achieved with smaller exercise dosages than stated in the generic recommendations for breast cancer.

Practical suggestions for harms reporting in exercise oncology: the Exercise Harms Reporting Method (ExHaRM)

The volume of high-quality evidence supporting exercise as beneficial to cancer survivors has grown exponentially; however, the potential harms of exercise remain understudied. Consequently, the trade-off between desirable and undesirable outcomes of engaging in exercise remains unclear to clinicians and people with cancer. Practical guidance on collecting and reporting harms in exercise oncology is lacking. We present a harms reporting protocol developed and refined through exercise oncology trials since 2015.Development of the Exercise Harms Reporting Method (ExHaRM) was informed by national and international guidelines for harms reporting in clinical trials involving therapeutic goods or medical devices, with adaptations to enhance applicability to exercise. The protocol has been adjusted via an iterative process of implementation and adjustment through use in multiple exercise oncology trials involving varied cancer diagnoses (types: breast, brain, gynaecological; stages at diagnosis I-IV; primary/recurrent), and heterogeneous exercise intervention characteristics (face to face/telehealth delivery; supervised/unsupervised exercise). It has also involved the development of terms (such as, adverse outcomes, which capture all undesirable physical, psychological, social and economic outcomes) that facilitate the harms assessment process in exercise.ExHaRM involves: step 1: Monitor occurrence of adverse outcomes through systematic and non-systematic surveillance; step 2: Assess and record adverse outcomes, including severity, causality, impact on intervention and type; step 3: Review of causality by harms panel (and revise as necessary); and step 4: Analyse and report frequencies, rates and clinically meaningful details of all-cause and exercise-related adverse outcomes.ExHaRM provides guidance to improve the quality of harms assessment and reporting immediately, while concurrently providing a framework for future refinement. Future directions include, but are not limited to, standardising exercise-specific nomenclature and methods of assessing causality.

Integrative Approaches to the Treatment of Cancer

A significant proportion of cancer patients use forms of complementary medicine or therapies. An integrative approach to cancer management combines conventional medicine with evidence-based complementary medicines/therapies and lifestyle interventions, for the treatment and prevention of disease and the optimisation of health. Its basis is a holistic one; to treat the whole person, not just the disease. It makes use of adjunct technologies which may assist the clinician in diagnosis of early carcinogenesis and monitoring of treatment effectiveness. Many factors contribute to the development of cancer including some which are largely modifiable by the patient and which oncologists may be in a position to advise on, such as stress, poor nutrition, lack of physical activity, poor sleep, and Vitamin D deficiency. An integrative approach to addressing these factors may contribute to better overall health of the patient and better outcomes. Evidence-based complementary medicine approaches include the use of supplements, herbal medicine, various practices that reduce stress, and physical therapies. Individualised to the patient, these can also help address the symptoms and signs associated with cancer and its orthodox treatment.

Building the plane while it's flying: implementation lessons from integrating a co-located exercise clinic into oncology care

Background

Despite its therapeutic role during cancer treatment, exercise is not routinely integrated into care and implementation efforts are largely absent from the literature. The aim of this study was to evaluate a strategy to integrate the workflow of a co-located exercise clinic into routine care within a private oncology setting in two clinics in the metropolitan region of Western Australia.

Methods

This prospective evaluation utilised a mixed methods approach to summarise lessons learned during the implementation of an integrated exercise workflow and supporting implementation plan. Data collection was informed by the RE-AIM (Reach, Effectiveness, Adoption, Implementation, Maintenance) framework. Reports detailing utilisation of the exercise service and its referral pathways, as well as patient surveys and meeting minutes documenting the implementation process informed the evaluation.

Results

The co-located exercise service achieved integration into routine care within the clinical oncology setting. Patient utilisation was near capacity (reach) and 100% of clinicians referred to the service during the 13-month evaluation period (adoption). Moreover, ongoing adaptations were made to improve the program (implementation) and workflows were integrated into standard operating practices at the clinic (maintenance). The workflow performed as intended for ~70% of exercise participants (effectiveness); however, gaps were identified in utilisation of the workflow by both patients and clinicians.

Conclusion

Integration of exercise into standard oncology care is possible, but it requires the ongoing commitment of multiple stakeholders across an organisation. The integrated workflow and supporting implementation plan greatly improved utilisation of the co-located exercise service, demonstrating the importance of targeted implementation planning. However, challenges regarding workflow fidelity within and across sites limited its success highlighting the complexities inherent in integrating exercise into clinical oncology care in a real-world setting.

Life style and interaction with microbiota in prostate cancer patients undergoing radiotherapy: study protocol for a randomized controlled trial

Background

Prostate cancer (PCa) is the second most common cancer in men worldwide. The standard non-surgical approach for localized PCa is radiotherapy (RT), but one of the limitations of high-dose RT is the potential increase in gastrointestinal and genitourinary toxicities. We present the protocol of the Microstyle study, a multicentre randomized two-arm crossover clinical trial. The primary outcome will be assessed at the end of 6-month intervention, by measuring the change in adherence to a healthy lifestyle score. The hypothesis is that modifying lifestyle we change microbiome and improve quality of life and decrease side effects of RT.

Methods

Study participants will be recruited among men undergoing RT in two Italian centers (Milan and Naples). We foresee to randomize 300 patients in two intervention arms: Intervention Group (IG) and Control Group (CG). Participants allocated to the IG will meet a dietitian and a physiotherapist before RT to receive personalized diet and exercise recommendations, according to their health status, to improve overall lifestyle and reduce side effects (bowel and/or urinary problems). Dietitian and physiotherapist will work together to set individualized goals to reduce or eliminate side effects and pain according to their health status. All participants (IG) will be given a pedometer device (steps counter) in order to monitor and to spur participants to increase physical activity and reduce sedentary behavior. Participants included in the CG will receive baseline general advice and materials available for patients undergoing RT. According to the cross-over design, the CG will cross to the intervention approach after 6-month, to actively enhance compliance towards suggested lifestyle recommendations for all patients.

Discussion

This trial is innovative in its design because we propose a lifestyle intervention during RT, that includes both dietary and physical activity counselling, as well as monitoring changes in microbiome and serum biomarkers. The promotion of healthy behaviour will be initiated before initiation of standard care, to achieve long lasting effects, controlling side effects, coping with feelings of anxiety and depression and improve efficacy of RT.

Towards best practice in the delivery of prescribed exercise via telehealth for individuals diagnosed with cancer: A randomised controlled trial protocol

Introduction

There is a plethora of evidence supporting the therapeutic effects of regular exercise for individuals diagnosed with cancer, particularly during active treatment. The COVID-19 pandemic has complicated delivery of face-to-face exercise programs for individuals with cancer, particularly as this cohort is at much higher risk of morbidity and mortality. The proposed randomised controlled trial explores best practice and assesses the feasibility of exercise programs delivered via Telehealth for individuals diagnosed with cancer.

Methods

Participants (n = 160) must have a current cancer diagnosis, must be undergoing active treatment, receive medical clearance, and have access to a smart device to participate in supervised exercise. Participants will be randomly assigned (two arms; 1:1) to supervised exercise delivered via Telehealth (Coviu) or usual care (receiving physical activity guidelines). Telehealth arm participants will receive an individualised program according to their health status, comorbidities, and exercise history, delivered weekly for eight weeks by an Accredited Exercise Physiologist in a group setting. Outcome measures will assess feasibility, psychological wellbeing, quality of life, symptom management, physical activity and fitness levels. A Telehealth arm participant sub-sample will have the opportunity to share their experience and feedback via an online interview at the intervention completion.

Ethics and dissemination

Outcomes from this study will create evidence to inform best practice for the safe delivery of exercise via Telehealth for individuals diagnosed with cancer. Evidence will be published in peer-reviewed journals and may be presented at national and international conferences. Ethics approval was obtained at the University of Canberra (Project ID: 4604. Version 2: 1st March 2022).

Immunoprotecting Effects of Exercise Program against Ovarian Cancer: A Single-Blind, Randomized Controlled Trial

Exercise is known to help the immune function of cancer survivors after cancer cell removal, but there is little information about the effect of exercise on ovarian cancer survivors. We conducted this study to investigate the effects of exercise training on the physical fitness and innate immunity of ovarian cancer survivors (OCS). Twenty-seven OCS between forty-two and sixty-one years of age volunteered for this study. The participants were divided into a control group (COG, n = 15) and an exercise group (EXG, n = 12). The mean (SD) age was 51.07 (5.67) years, and the mean post-operation period was 45.96 (5.88) months. EXG participated in regular exercise training 6 days a week for 12 weeks. Body weight, fat mass, and body mass index of EXE were significantly decreased compared with those of COG. The muscle mass in EXE was increased compared to that of COG. Physical fitness factors showed positive changes in EXG compared to COG. We found that exercise training enhanced lymphocyte and neutrophil counts of leucocytes and total natural killer (NK) and natural killer T (NKT) cell counts of lymphocytes through improved body composition and physical fitness after 12 weeks. Moreover, we found that improved innate immune cells through the exercise program were achieved through an increase in NKG2D+NK receptors and a decrease in KIR2DL3+NK receptors in OCS.

A Randomised, Comparative, Effectiveness Trial Evaluating Low- versus High-Level Supervision of an Exercise Intervention for Women with Breast Cancer: The SAFE Trial

The aim of this comparative, effectiveness trial was to evaluate the safety, feasibility and effect of an exercise intervention delivered via low-level versus high-level supervision. The target population were women who were diagnosed with ≥stage II breast cancer, had ≥ one comorbidity and/or persistent treatment-related side-effects, and were insufficiently physically active. Sixty women (50 ± 9 years) were randomized to the low-supervision group (n = 30) or high-supervision group (n = 30). The low-supervision group participated in a 12-week, individually-tailored exercise intervention supported by five supervised sessions with an exercise professional. The high-supervision group participated in the same exercise intervention but received 20 supervised sessions across the 12-week period. The target weekly dosage of 600 metabolic equivalent minutes of exercise per week (MET-mins/wk) and the session content, such as safety and behaviour change topics, were standardized between the groups. The primary outcomes were intervention safety, defined as the number, type, and severity of exercise-related adverse events (e.g., musculoskeletal injury or exacerbated treatment-related side effects), and feasibility, which was defined as compliance to target exercise dosage. The effect of the intervention on quality of life, physical activity, self-efficacy, fitness, and strength was also assessed (pre- and post-intervention, and at 12-week follow-up). The intervention was safe, with no exercise-related adverse events of grade 3 or above in either group. Both groups reported high compliance to the target exercise dosage (median MET-mins/wk: High = 817; Low = 663), suggesting the exercise intervention was feasible, irrespective of supervision level. Improvements in quality of life, physical activity and fitness were observed post-intervention and maintained at follow-up for both groups (p < 0.05). Only the high-supervision group showed clinically-relevant improvements in strength and self-efficacy at post-intervention (p < 0.05). Individually-targeted exercise delivered under high- or low-levels of supervision is safe, feasible and beneficial for women with stage II+ breast cancer. Future research needs to assess whether the greater gains observed in the group who received higher supervision may contribute to longer term maintenance of physical activity levels and overall health benefits.

Rehabilitation Needs for Patients Undergoing CAR T-Cell Therapy

PURPOSE OF REVIEW

Chimeric antigen receptor (CAR) T-cell therapy is a relatively new, innovative treatment strategy to manage refractory hematological cancers, including some types of leukemia, lymphoma, and multiple myeloma. This article outlines the CAR T-cell therapy process, toxicity, and complications, along with an overview of the currently known short- and long-term physical and functional sequelae that will be helpful for general or oncology rehabilitation specialists caring for these patients.

RECENT FINDINGS

There is a dearth of literature on the topic of rehabilitation of patients receiving CAR T-cell therapy. Rehabilitation practices can be extrapolated from the limited functional information on patients who have completed treatment for lymphoma and multiple myeloma. Patients present with cognitive impairment, muscle weakness, reduced exercise capacity, neuropathy, and cancer-related fatigue. Physical activity and rehabilitation programs may be beneficial to address fatigue, psychological symptoms, and quality of life. There is limited rehabilitation research in patients receiving CAR T-cell therapy. These patients may present with general deconditioning and neurological complications which translate to neuromuscular and cognitive impairment that benefit from multidisciplinary rehabilitation intervention prior to, during, and after treatment. Studies measuring the impairments at baseline and evaluation of the impact of rehabilitation practices are much needed to support this.

Awareness and attitudes of oncology physicians recommending exercise to patients with cancer

Objectives: The aim of our study was to evaluate oncology physicians’ attitudes and awareness toward recommending exercise to their patients with cancer.

Patients and methods: A total of 86 oncology physicians (52 males, 34 females; mean age: 46.7±10.9 years; range, 26 to 60 years) were included in the study between June 2019 and September 2019. A questionnaire was prepared to evaluate the physicians' perspectives about exercise and it consisted of five main sections including the physician's exercise habits, physicians’ attitudes toward recommending exercise, the effects of exercise on cancer-related symptoms and cancer treatments, whether there was an exercise unit in the hospital, and whether the physician was referring the patients and on which subjects the physicians were willing to receive training.

Results: A total of 87.2% of the physicians recommended exercise to their patients. There were three reasons for physicians who did not recommend exercise: “I don’t have enough training to recommend exercise; I don’t know which type of exercise to recommend; and I don’t know what I should pay attention while recommending exercise.” A total of 83.7% physicians considered that exercise reduced the symptoms associated with cancer. A total of 73.3%, 64%, and 80.2% physicians believed that exercise increased the effectiveness of chemotherapy, radiotherapy, and immunotherapy, respectively. About 94.2% of the physicians were willing to be trained on the effects of exercise in cancer.

Conclusion: Oncology physicians believe that exercise has positive effects on cancer; however, they still need training on this subject.

Protective effects of physical activity in colon cancer and underlying mechanisms: A review of epidemiological and biological evidence

Numerous epidemiological studies indicate that physical activity has a protective effect against colon cancer development and progression. Further, the relevant biological mechanisms where physical activity or exercise may improve survival have also been initially examined. In this review, we provide an overview of the epidemiological evidence to date which comprises 16 cohort studies of the effects of physical activity on colon cancer outcomes including cancer recurrence, cancer-specific and overall survival. Moreover, we present four potential mechanisms involving shear pressure, systemic milieu alteration, extracellular vesicles, and immune function by which physical activity and exercise may favorably impact colon cancer. Research currently in progress will provide definitive evidence of survival benefits resulting from exercise and future work will help clarify the role of targeted exercise and the relevant mechanisms involved.

Association of Demographic and Cancer-Specific Factors on Health Behavior Recommendations Specific to Cancer Prevention and Control Among Adolescent and Young Adult Survivors of Childhood Cancer

Purpose: Adolescent and young adult survivors of childhood cancer (AYA) are at risk for long-term health problems that are exacerbated by not meeting health behavior recommendations (e.g., exercise). To identify AYA at risk for not meeting health behavior recommendations, we explored demographic (e.g., age) and cancer-specific (e.g., intensity of treatment) factors associated with not meeting specific health behavior recommendations that have implications for cancer prevention and control. Methods: Regression (linear/binary) was used to examine demographic and cancer-specific associates regarding fruit/vegetable intake, binge drinking, sleep duration, sunscreen use, tobacco use, and physical activity among 307 AYA (Mage = 20.33, range = 15-34) across three combined studies, treated at a pediatric cancer center. Health behavior measures were adapted from The Health Behaviors Survey and the Youth Risk Behavior Surveillance System questionnaire. Results: AYA in general did not meet health behavior recommendations. Compared with AYA with public insurance, AYA with private insurance (β = -0.19, p < 0.01) were more likely to meet multiple health behavior recommendations. AYA at greatest risk for not meeting specific health behaviors were more likely to be diagnosed in middle childhood (11.35years) compared with early childhood (8.38years), be closer to diagnosis (8.77years vs. 11.76years) and closer to treatment completion (6.97years vs. 9.91years), and have a solid tumor (32.7%) compared with a brain tumor (10.6%). Conclusion: Not meeting health behavior recommendations is common among AYA survivors of childhood cancer. Early education in the context of survivorship care is critical to provide teachable moments to AYA; such interventions might impact future long-term health and reduce risk for secondary cancers.

Residual Impact of Concurrent, Resistance, and High-Intensity Interval Training on Fasting Measures of Glucose Metabolism in Women With Insulin Resistance

We sought to assess the residual effects (post 72-h training cessation) on fasting plasma glucose (FPG) and fasting insulin (FI) after 12-weeks of high-intensity interval training (HIIT), resistance training (RT), or concurrent training (CT) in women with insulin resistance (IR). We also aimed to determine the training-induced, post-training residual impact of CT. A total of adult 45 women (age 38.5±9.2years) were included in the final analysis and were assigned to a control (CG; n=13, BMI 28.3±3.6kg/m2), HIIT [n=14, BMI 28.6±3.6kg/m2, three sessions/wk., 80-100% of the maximum heart rate (HRmax)], RT [n=8, BMI 29.4±5.5kg/m2, two sessions/wk., 8-10 points of the modified Borg, corresponding to 20 to 50% range of one maximum repetition test (1RM)], or CT group (n=10, BMI 29.1±3.0kg/m2, three sessions/wk., 80-100% of HRmax, and 8-10 Borg, or 20 to 50% range of 1RM, to each HIIT and RT compounds), with the latter including both HIIT and RT regimens. Training interventions lasted 12-weeks. The main outcomes were FPG and FI measured at pre- and 24-h and 72-h post-training (FPG24h, FI24h, and FPG72h, FI72h, respectively). Secondary endpoints were body composition/anthropometry and the adiposity markers waist circumference (WC) and tricípital skinfold (TSF). The residual effects 72-h post-training [delta (∆)] were significantly poorer (all p<0.01) in the CT group (∆FPG72h+6.6mg/dl, η 2: 0.76) than in the HIIT (∆FPG72h+1.2mg/dl, η 2: 0.07) and RT (∆FPG72h+1.0mg/dl, η 2: 0.05) groups. These findings reveal that HIIT reduces FPG and RT reduces FI 24-h post-training; both exercise interventions alone have remarkably better residual effects on FPG and FI (post-72h) than CT in women with insulin resistance.

Associations of Physical Activity and Exercise with Health-related Outcomes in Patients with Melanoma During and After Treatment: A Systematic Review

Purpose:

Although exercise medicine is recommended to counter treatment-related side-effects and improve health-related outcomes of patients affected by different cancers, no specific recommendations exist for patients with melanoma. As a result, we systematically examined the current evidence regarding the effects of physical activity and exercise on objectively-measured and patient-reported outcomes among patients with melanoma.

Methods:

Searches were conducted in PubMed, CINAHL, EMBASE, SPORTDiscus, and Web of Science databases. This review included published data involving physical activity or exercise and objectively-measured or patient-reported outcomes of patients with cutaneous melanoma. The quality of included studies was assessed using the McMaster University Critical Appraisal Tool for Quantitative Studies.

Results:

Six studies including 882 patients with melanoma were included. Studies presented heterogeneity of design with 2 cross-sectional surveys, 2 retrospective analyses, and 2 non-randomized intervention trials. No statistically significant change in quality of life, fatigue, physical function, cardiorespiratory fitness, body composition, psychological distress, cognitive function, or treatment-related side-effects were attributable to physical activity or exercise. Importantly, physical activity or exercise during melanoma treatment or into survivorship did not adversely impact patients/survivors.

Conclusion:

In summary, physical activity or exercise did not adversely impact quality of life, objectively-measured or patient-reported outcomes in patients with melanoma. In addition, there is a paucity of quality studies examining the effects of physical activity or exercise on patients with melanoma throughout the cancer care continuum.

Exercise Therapy and Radiation Therapy for Cancer: A Systematic Review

PURPOSE

Exercise therapy (ET) is shown to improve toxicity and surrogates of survival for patients receiving chemotherapy. Current National Comprehensive Cancer Network (NCCN) guidelines lack recommendations for concurrent radiation therapy (RT) and ET. The main objective was to determine the impact of concurrent ET + RT with respect to (1) acceptability, feasibility, safety; and (2) to demonstrate how incorporating ET in cancer treatment can enhance patient-reported outcomes (PROs) and physical function-defined as strength or exercise capacity.

METHODS AND MATERIALS

A PICOS/PRISMA selection protocol was used to search PubMed, Cumulative Index of Nursing and Allied Health Literature (CINAHL), and Cochrane Review for prospective randomized controlled trials evaluating concurrent ET + RT, including >10 patients and with 1 or more study arms. Acceptability, feasibility, and safety rates were calculated. PROs were assessed with study-specific metrics. Physical function was defined as improvements in strength or range of motion. Statistically significant improvement was defined by P <.05.

RESULTS

Twenty-six of 693 screened studies including 1563 patients (831 receiving exercise, 732 controls) with localized breast cancer (67.1% of patients), prostate cancer (27.4%), head and neck cancers (2.8%), and spinal metastases (2.8%) were assessed. Objective 1: Among 3385 patients approached for ET, 1864 (55.1%) accepted the treatment; of those, 1563 patients (83.9%) completed the trials. Objective 2: Statistical improvements were noted in these PROs: quality of life (14 of 15 studies), fatigue (12 of 16 studies), mood/depression (9 of 13), and anxiety (6 of 7). Physical function improved statically in 16 of 16 studies.

CONCLUSIONS

Combination ET + RT is safe and well-tolerated with improvements in PROs and physical function. Additional studies are needed in patients with metastatic cancers to assess survival and to compare effectiveness of different exercise regimens.

A Systematic Review and Narrative Synthesis of Exercise Interventions to Manage Fatigue Among Children, Adolescents, and Young Adults with Cancer

Exercise is known to improve fatigue among adult cancer patients however there is limited understanding of this relationship in children, adolescents, and young adults (AYA) with cancer. The aim is to evaluate the effect of exercise on fatigue outcomes among children and AYA with cancer and to identify important parameters of exercise (frequency, intensity, time, type, and setting), which may be relevant for future intervention design. A systematic search of PubMed, MedLine, CENTRAL, Embase, and Web of Science databases was conducted in December 2019, for studies within the last decade, reporting the effect of exercise on fatigue among cancer patients and survivors 0-24 years of age. Quality assessment was conducted using the Physiotherapy Evidence Database (PEDro) and "Before/After Studies with No Control Group" scales. Seventeen studies (n = 681 participants) were included, of which six were randomized controlled trials (RCTs), and the remaining being pilot (n = 5) or feasibility studies (n = 6). Across studies there was great heterogeneity in intervention delivery, frequency (range: 1-7 days a week), time (range: 10-60 minutes), and duration (range: 3-24 weeks). A positive effect of exercise on fatigue was observed, however, most changes in fatigue were not statistically significant. Exercise is beneficial for reducing fatigue in young cancer patients. However, due to the heterogeneity and quality of existing interventions, firm conclusions about the most effective mode and format of exercise intervention cannot be drawn. There is a need for more definitive large-scale RCTs that can provide data of sufficient quality.

Feasibility and suitability of a graded exercise test in patients with aggressive hemato-oncological disease

Purpose

Physical activity promises to reduce disease-related symptoms and therapy-related side effects in patients suffering from aggressive lymphoma (L) or acute leukemia (AL). For an efficient training program, determination of patients’ physical capacity with a purposive exercise test is crucial. Here, we evaluated the feasibility and suitability of a graded exercise test (GXT) frequently applied in patients suffering from solid tumors by assessing whether patients achieved criteria for maximal exercise testing according to the American College of Sports Medicine (ACSM).

Methods

The GXT was performed by 51 patients with an aggressive L or AL prior to the start or in the earliest possible phase of high-dose chemotherapy, following a recommended protocol for cancer patients, starting at 20 Watts (W), with an increase of 10 W/min until volitional exhaustion. Subsequently, we investigated whether the following ACSM criteria were fulfilled: (1) failure of heart rate to increase despite increasing workload, (2) post-exercise capillary lactate concentration ≥ 8.0 mmol L⁻¹, (3) rating of perceived exertion at exercise cessation > 17 on the 6–20 Borg Scale.

Results

Out of 51 patients, two, six, and 35 participants met the first, second, and third criterion, respectively. No relevant relationships between the completion of the criteria and patients’ characteristics (e.g., gender, age) were found.

Conclusion

Although results of this study suggest a general feasibility of the applied GXT, the ACSM criteria were not met by the majority of the participants. Therefore, this study raises doubts about the suitability of the GXT protocol and the ACSM criteria for this group of patients.

Should healthcare organisations offer ongoing rehabilitation services for patients undergoing haematopoietic cell transplant? A narrative review

Purpose

Hematopoietic stem cell transplant (HSCT) patients can suffer from long-term transplant-related complications that affect their quality of life and daily activities. This study, a narrative review, aims to report the impact of HCT complications, the benefits of rehabilitation intervention, the need for long-term care and highlights the research gap in clinical trials involving rehabilitation.

Design/methodology/approach

A comprehensive search strategy was performed on several databases to look for relevant articles published from 1998 to 2018. Articles published in English with the following terms were used: hematopoietic stem cell transplant, chronic graft-versus-host disease, rehabilitation, exercise, physical therapy, occupational therapy. A patient/population, intervention, comparison, and outcomes (PICO) framework was employed to ensure that the search strategies were structured and precise. Study year, design, outcome, intervention, sample demographics, setting and study results were extracted.

Findings

Of the 1,411 records identified, 51 studies underwent title/abstract screening for appropriateness, 30 were reviewed in full, and 19 studies were included in the review. The review found that, for the majority of patients who underwent HSCT and developed treatment-related complications, rehabilitation exercises had a positive impact on their overall quality of life. However, exercise prescription in this patient group has not always reflected the scientific approach; there is a lack of high-quality clinical trials in general. The review also highlights the need to educate healthcare policymakers and insurance companies responsible for rationing services to recognise the importance of offering long-term follow-up care for this patient group, including rehabilitation services.

Practical implications

A large number of HSCT patients require long-term follow-up from a multidisciplinary team, including rehabilitation specialists. It is important for healthcare policymakers and insurance companies to recognise this need and take the necessary steps to ensure that HSCT patients receive adequate long-term care. This paper also highlights the urgent need for high-quality rehabilitation trials to demonstrate the feasibility and importance of rehabilitation teams.

Originality/value

Healthcare policymakers and insurance companies need to recognise that transplant patients need ongoing physiotherapy for early identification of any functional impairments and appropriate timely intervention.

Androgen deprivation in prostate cancer: benefits of home-based resistance training

INTRODUCTION

Androgen deprivation therapy (ADT) has detrimental effects on body composition, metabolic health, physical functioning, bone mineral density (BMD) and health-related quality of life (HRQOL) in men with prostate cancer. We investigated whether a 12-month home-based progressive resistance training (PRT) programme, instituted at the start of ADT, could prevent these adverse effects.

METHODS

Twenty-five patients scheduled to receive at least 12 months of ADT were randomly assigned to either usual care (UC) (n = 12) or PRT (n = 13) starting immediately after their first ADT injection. Body composition, body cell mass (BCM; a functional component of lean body mass), BMD, physical function, insulin sensitivity and HRQOL were measured at 6 weeks and 6 and 12 months. Data were analysed by a linear mixed model.

RESULTS

ADT had a negative impact on body composition, BMD, physical function, glucose metabolism and HRQOL. At 12 months, the PRT group had greater reductions in BCM by - 1.9 ± 0.8 % (p = 0.02) and higher gains in fat mass by 3.1 ± 1.0 % (p = 0.002), compared to the UC group. HRQOL domains were maintained or improved in the PRT versus UC group at 6 weeks (general health, p = 0.04), 6 months (vitality, p = 0.02; social functioning, p = 0.03) and 12 months (mental health, p = 0.01; vitality, p = 0.02). A significant increase in the Matsuda Index in the PRT versus UC group was noted at 6 weeks (p = 0.009) but this difference was not maintained at subsequent timepoints. Between-group differences favouring the PRT group were also noted for physical activity levels (step count) (p = 0.02). No differences in measures of BMD or physical function were detected at any time point.

CONCLUSION

A home-based PRT programme instituted at the start of ADT may counteract detrimental changes in body composition, improve physical activity and mental health over 12 months.

Exercise intensity prescription in cancer survivors: ventilatory and lactate thresholds are useful submaximal alternatives to VO2peak

PURPOSE

Most studies with cancer survivors use percentages of peak oxygen uptake (VO2peak) for intensity prescription. Lactate or ventilatory thresholds might be useful submaximal alternatives, but this has never been investigated. Therefore, we aimed at comparing three training sessions prescribed using %VO2peak (reference), lactate thresholds, and ventilatory thresholds in terms of meeting the vigorous-intensity zone, physiological, and psychological responses.

METHODS

Twenty breast (58 ± 10 years) and 20 prostate cancer survivors (68 ± 6 years), 3.6 ± 2.4 months after primary therapy, completed a maximal cardiopulmonary exercise test and three vigorous training sessions in randomized order: 38 min of cycling at 70% VO2peak (M-VO2peak), 97% of individual anaerobic lactate threshold (M-IAT), and 67% between ventilatory thresholds 1 and 2 (M-VT). Heart rate (HR), blood lactate concentration (bLa), perceived exertion, and enjoyment were assessed.

RESULTS

Cancer survivors exercised at 75 ± 23, 85 ± 18, and 79 ± 19 W during M-VO2peak, M-IAT, and M-VT (p > .05). Sessions could not be completed in 3, 8, and 6 cases. Session completers showed HR of 82 ± 7, 83 ± 9, and 84 ± 8 %HRpeak and bLa of 3.7 ± 1.9, 3.9 ± 0.9, and 3.9 ± 1.5 mmol·l-1, which was not different between sessions (p > .05). However, variance in bLa was lower in M-IAT compared to M-VO2peak (p = .001) and to M-VT (p = .022).

CONCLUSION

All intensity prescription methods on average met the targeted intensity zone. Metabolic response was most homogeneous when using lactate thresholds.

IMPLICATIONS FOR CANCER SURVIVORS

Submaximal thresholds are at least as useful as VO2peak for intensity prescription in cancer survivors. Overall, slightly lower percentages should be chosen to improve durability of the training sessions.

Optimising Web-Based Computer-Tailored Physical Activity Interventions for Prostate Cancer Survivors: A Randomised Controlled Trial Examining the Impact of Website Architecture on User Engagement

BACKGROUND

Web-based computer-tailored interventions can assist prostate cancer survivors to become more physically active by providing personally relevant behaviour change support. This study aimed to explore how changing the website architecture (free choice vs. tunnelled) impacted engagement within a physical activity computer-tailored intervention targeting prostate cancer survivors.

METHODS

On a 2:2:1 ratio, 71 Australian prostate cancer survivors with local or locally advanced disease (mean age: 66.6 years ± 9.66) were randomised into either a free-choice (N = 27), tunnelled (N = 27) or minimal intervention control arm (N =17). The primary outcome was differences in usage of the physical activity self-monitoring and feedback modules between the two intervention arms. Differences in usage of other website components between the two intervention groups were explored as secondary outcomes. Further, secondary outcomes involving comparisons between all study groups (including the control) included usability, personal relevance, and behaviour change.

RESULTS

The average number of physical activity self-monitoring and feedback modules accessed was higher in the tunnelled arm (M 2.6 SD 1.3) compared to the free-choice arm (M 1.5 SD 1.4), p = 0.01. However, free-choice participants were significantly more likely to have engaged with the social support (p = 0.008) and habit formation (p = 0.003) 'once-off' modules compared to the standard tunnelled arm. There were no other between-group differences found for any other study outcomes.

CONCLUSION

This study indicated that website architecture influences behavioural engagement. Further research is needed to examine the impact of differential usage on mechanisms of action and behaviour change.

The Role of Telehealth During the COVID-19 Pandemic Across the Interdisciplinary Cancer Team: Implications for Practice

Objective

This literature review aims to explore the role of telehealth during the COVID-19 pandemic across the interdisciplinary cancer care team.

Data Sources

Electronic databases including CINAHL, MEDLINE, PsychINFO, Scopus, and gray literature were searched using Google Scholar up until September 2020.

Conclusion

Although the safe and effective delivery of cancer care via telehealth requires education and training for health care professionals and patients, telehealth has provided a timely solution to the barriers caused by the COVID-19 pandemic on the delivery of interdisciplinary cancer services. Globally, evidence has shown that telehealth in cancer care can leverage an innovative response during the COVID-19 pandemic but may provide a long-lasting solution to enable patients to be treated appropriately in their home environment. Telehealth reduces the travel burden on patients for consultation, affords a timely solution to discuss distressing side effects, initiate interventions, and enable possible treatment additions and/or changes.

Implications for Nursing Practice

Global public health disasters pose significant and unique challenges to the provision of necessary services for people affected by cancer. Oncology nurses can provide a central contribution in the delivery of telehealth through transformational leadership across all domains and settings in cancer care. Oncology nurses provide the “hub of cancer care” safely embedded in the interdisciplinary team. Telehealth provides a solution to the current global health crisis but could also benefit the future provision of services and broad reach clinical trials.

Physical Activity and Exercise Guidelines for People With Cancer: Why Are They Needed, Who Should Use Them, and When?

OBJECTIVES

This report describes why there is a need for cancer-specific physical activity and exercise prescription guidelines, how the recommendations in the guidelines were derived, and how these guidelines can be used and by whom, to reduce cancer-related burden.

DATA SOURCE

Professional organizations and peer-reviewed papers.

RESULTS

Higher physical activity levels post-cancer diagnosis has been consistently associated with improved morbidity and/or survival outcomes for all cancers studied to date. As such, although physical activity recommendations for those post-cancer are largely generic and tend to replicate physical activity guidelines endorsed for healthy adults, the cancer-specific epidemiological evidence-base suggest this to be appropriate. These guidelines should be endorsed and promoted by all members of the cancer care team, across all phases of cancer survivorship. Cancer-specific exercise prescription guidelines are supported by a clinical trial evidence-base and enable targeted exercise prescription for the benefit of the individual patient. Any member of the cancer care team can refer patients at any time to exercise professionals, who will use these exercise guidelines to direct their provision of exercise as medicine.

CONCLUSION

The prevention of physical activity declines and small increases in physical activity levels during and following cancer treatment is appropriate for the majority. Further, physical activity promotion, alongside incorporation of planned, purposeful, targeted and individualized exercise, has significant potential for reducing morbidity and mortality of cancer worldwide.

IMPLICATIONS FOR NURSING PRACTICE

Nurses are well-placed to regularly encourage patients to participate in physical activity, and to refer patients to exercise professionals, during and following their cancer treatment.

Effect of the exercise programme on the quality of life of prostate cancer survivors: A randomized controlled trial

AIM

The aim of this study was to investigate the effect of the exercise programme on the quality of life of prostate cancer (PCa) survivors.

METHODS

A randomized controlled, parallel trial was conducted from April 2017 to January 2018 on 80 PCa survivors. They were randomly assigned to intervention and control groups (n = 40 in each group). The exercise programme was designed based on the self-management approach (SMA). The intervention group participated in a 12-week exercise programme consisting of one session of group exercise and three sessions of individual exercise per week using exercise facilities in the community. Data were collected using the quality of life questionnaires and the follow-up checklist.

RESULTS

In the intervention group, statistically significant improvements in physical, role, emotional, social and sexual functions were reported. Also, the patients in this group reported reduced fatigue, insomnia, constipation, diarrhoea, urinary, bowel and hormonal treatment-related symptoms in comparison with before the exercise programme (p < 0.05).

CONCLUSIONS

Nurses are suggested to plan for improving the participation of PCa survivors in exercise programmes using exercise facilities in the community in order to reduce the complications of treatment and improve their quality of life.

Resistance training in breast cancer patients undergoing primary treatment: a systematic review and meta-regression of exercise dosage

BACKGROUND

Exercise is recognised as an adjunct therapy for breast cancer patients; however, little is known about the resistance training dose-response. We conducted a systematic review and meta-regression to examine the resistance training dose-response (i.e., volume and intensity) in breast cancer patients undergoing primary treatment.

METHODS

Searches in MEDLINE, CINAHL, and SPORTDiscus were conducted for studies published up to November 2019. Experimental studies that evaluated resistance-based exercise interventions in women with breast cancer undergoing primary treatment were included. Information about resistance training components, average change and change per week, as well as standardised mean difference were extracted, and used for meta-regression analysis. Outcome measures were upper and lower body muscle strength and body composition.

RESULTS

10 trials were included in the systematic review and 4 trials in the dose-response analysis. Resistance training weekly prescribed volume was inversely associated with increases in upper and lower body muscle strength (r² = 98.1-100%; p = 0.009), although there was no relationship between resistance training intensity and strength gains. There was insufficient data for the dose-response analysis of body mass index, percent body fat, and lean mass.

CONCLUSION

Low volume resistance training might be a suitable exercise recommendation for breast cancer patients undergoing primary treatment producing superior benefits for muscle strength compared to higher volume training, regardless of the training intensity. Low volume resistance training may provide a conservative and appropriate approach for breast cancer patients, allowing gradual progression and modification throughout the exercise program.

The role of exercise in the management of adverse effects of androgen deprivation therapy for prostate cancer: a rapid review

PURPOSE

Prostate cancer (PCa) is the most commonly diagnosed cancer in Australia, accounting for one quarter of all new cancer diagnoses for males. Androgen deprivation therapy (ADT) is the standard first-line therapy for metastatic PCa but is also used across much of the spectrum of disease. Unfortunately, debilitating adverse effects are a significant and largely unavoidable feature of ADT. A recent systematic review of adverse effects of ADT identified 19 sub-groups classified according to the Common Terminology Criteria for Adverse Events (CTCAE) Version 5.0. The potential for multiple simultaneous adverse effects, their associated management and the impact of adverse effects on cancer outcomes and quality of life are important considerations in the treatment and supportive care of men with PCa. Exercise is increasingly being recognized as an efficacious strategy in managing these adverse effects.

METHODS

A rapid review was undertaken to examine the role of exercise in the management of the most commonly reported ADT adverse effects classified according to the CTCAE sub-groups. A systematic search was conducted in Medline, PsycINFO, Google Scholar and Google for the years 2010 to September 2019 to identify the benefits of exercise in managing the adverse effects of ADT for PCa.

RESULTS

There is strong evidence for exercise as medicine in addressing several of the adverse effects of PCa such as loss of muscle mass and strength, fatigue and declining physical function. Moderate level evidence for PCa exists for exercise-induced improvements in depression and anxiety, bone loss, and sexual dysfunction. While evidence of the effectiveness of exercise is lacking for many adverse effects of ADT for PCa, evidence in the cancer population as a whole or other clinical populations is strong, and many clinical guidelines recommend exercise as a fundamental part of their clinical management. With the exception of gynaecomastia and breast pain, there is increasing evidence (PCa, cancer or other clinical populations) to suggest that exercise has the potential to reduce and even prevent many of the adverse effects of ADT, thus improving survivorship outcomes for men with PCa.

CONCLUSION

Exercise has the potential to reduce and even prevent many of the adverse effects of ADT, thus improving survivorship outcomes for men with PCa. The use of exercise for PCa management has the potential to translate into health and economic benefits in improved quality of life and fewer complications, resulting in savings to the health care system, enhanced productivity and reduced patient and carer burden. Exercise thus has the potential to improve quality of life for this population as well as generate significant cost savings.

Sport Medicine in the Prevention and Management of Cancer

Physical inactivity is a major concern in cancer patients despite the established preventative and therapeutic effects of regular physical exercise for this patient group. Sport not only plays an important role in supporting the development and maintenance of a physically active lifestyle but also is increasingly used as a health promotion activity in various populations. Nevertheless, the potential of sport as an effective strategy in the prevention and management of cancer has gained little attention. Based on the scant evidence to date, participation of cancer patients in supervised, well-tailored sport programs appears to be safe and feasible and is associated with an array of physical and psychological benefits. We propose that sport participation may serve as an alternative strategy in the prevention of cancer and sport medicine in the management of cancer. As with the traditional exercise modes, benefits derived from sport participation will be dependent on the sport undertaken and the physical/physiological, motor, and cognitive demands required. To this end, further work is required to develop a solid evidence base in this field so that targeted sport participation can be recommended for cancer patients.

Evidence Supports PA Prescription for Parkinson's Disease: Motor Symptoms and Non-Motor Features: A Scoping Review

Parkinson’s disease (PD) is a prevalent neurodegenerative disorder, which relates to not only motor symptoms, but also cognitive, autonomic, and mood impairments. The literature suggests that pharmacological or surgical treatment has a limited effect on providing relief of the symptoms and also restricting its progression. Recently, research on non-pharmacological interventions for people living with PD (pwPD) that alleviate their motor and non-motor features has shown a new aspect in treating this complex disease. Numerous studies are supporting exercise intervention as being effective in both motor and non-motor facets of PD, such as physical functioning, strength, balance, gait speed, and cognitive impairment. Via the lens of the physical profession, this paper strives to provide another perspective for PD treatment by presenting exercise modes categorized by motor and non-motor PD symptoms, along with its effects and mechanisms. Acknowledging that there is no “one size fits all” exercise prescription for such a variable and progressive disease, this review is to outline tailored physical activities as a credible approach in treating pwPD, conceivably enhancing overall physical capacity, ameliorating the symptoms, reducing the risk of falls and injuries, and, eventually, elevating the quality of life. It also provides references and practical prescription applications for the clinician.

i-Move, a personalised exercise intervention for patients with advanced melanoma receiving immunotherapy: a randomised feasibility trial protocol

INTRODUCTION

There is increasing evidence demonstrating the benefits of exercise in counteracting cancer treatment-related fatigue. Immunotherapy is an established treatment for advanced melanoma, and is associated with fatigue in a third of patients. The safety and efficacy of exercise in counteracting treatment-related fatigue in patients with advanced melanoma receiving immunotherapy are yet to be determined. This study aims to assess the safety, adherence to and acceptability of a mixed-methods parallel-group, pilot randomised controlled trial of a personalised, 12-week semi-supervised exercise programme prescribed by an exercise physiologist (iMove) in 30 patients with stage IV melanoma scheduled to commence immunotherapy: single agent ipilimumab, nivolumab or pembrolizumab, or combination ipilimumab and nivolumab. The trial will be used to provide preliminary evidence of the potential efficacy of exercise for managing fatigue.

METHODS AND ANALYSIS

Thirty participants will be recruited from a specialist cancer centre between May and September, 2019. Participants will be randomised 1:1 to receive iMove, or usual care (an information booklet about exercise for people with cancer). Feasibility data comprise: eligibility; recruitment and retention rates; adherence to and acceptability of exercise consultations, personalised exercise programme and study measures; and exercise-related adverse events. Patient-reported outcome measures assess potential impact of the exercise intervention on: fatigue, role functioning, symptoms and quality of life. Follow-up will comprise five time points over 24 weeks. Physical assessments measure physical fitness and functioning.

ETHICS AND DISSEMINATION

This study was reviewed and approved by the Peter MacCallum Cancer Centre Human Research Ethics Committee (HREC/48927/PMCC-2019). The findings from this trial will be disseminated via conference presentations and publications in peer-reviewed journals, and by engagement with clinicians, media, government and consumers. In particular, we will promote the outcomes of this work among the oncology community should this pilot indicate benefit for patients.

Exercise and Physical Activity in Patients with Osteosarcoma and Survivors

Exercise has the potential to positively affect patients with osteosarcoma by improvement of function, mitigation of disability, and maintenance of independence and quality of life. Exercise may also directly impact cancer treatment efficacy. This chapter examines the feasibility and use of exercise or physical activity as therapy in the treatment of osteosarcoma and its survivors. It additionally presents the benefits of physical activity as treatment and rehabilitation both preoperatively (prehabilitation) and postoperatively. This chapter will also discuss barriers to exercise and physical activity for patients with osteosarcoma and its survivors, emphasizing the need for a comprehensive and cohesive support system to promote its incorporation into patient treatment plans and ensure compliance.

Mechanisms of Physical Activity Behavior Change for Prostate Cancer Survivors: A Cluster Randomized Controlled Trial

Background

Exercise is beneficial for prostate cancer survivors. Therefore, understanding the mechanisms of physical activity (PA) behavior change is imperative.

Purpose

The ENGAGE study was an exercise intervention for prostate cancer survivors, which improved vigorous physical activity (VPA) at postintervention and follow-up. The purpose of this study was to assess (a) whether the intervention improved social cognitive determinants of behavior and (b) the extent to which social cognitive determinants mediated the effect of the exercise intervention on VPA.

Methods

Overall, 147 men consented to be involved in the study (intervention = 54, usual care = 93). Data from baseline, postintervention (12 weeks) and follow-up (6 months) were used in this analysis. Social cognitive determinants were measured using appropriate measures. VPA was measured using an adapted version of the Leisure-Time Exercise Questionnaire.

Results

Compared with the control condition, men in the intervention condition had higher task self-efficacy postintervention (+16.23; 95% confidence interval [CI] +9.19 to +23.31; effect size [d] = 0.85, p < .001) and at follow-up (+12.58; 95% CI = +4.45 to +20.71, d = 0.50, p = .002). Task self-efficacy partially mediated the effect of the exercise intervention on VPA (indirect effect: B = 19.90; 95% CI 1.56 to 38.25, p = .033).

Conclusion

The intervention improved the belief among prostate cancer survivors that they could perform challenging exercises for longer periods of time, which partially explained the positive effect of the intervention on VPA.

Exercise for advanced prostate cancer: a multicomponent, feasibility, trial protocol for men with metastatic castrate-resistant prostate cancer (EXACT)

BACKGROUND

Men with metastatic castrate-resistant prostate cancer can experience an array of treatment-related side effects. Accumulating evidence suggests exercise may alleviate some of these adversities and assist in disease management. However, empirical evidence in advanced prostate cancer patients remains limited. The purpose of this study is to determine whether men with metastatic prostate cancer, who are ineligible for high-intensity exercise, can partake in a home-based, moderate-intensity exercise program and the impact of doing so on quality of life and physical fitness parameters.

METHODS

Thirty men with adenocarcinoma of the prostate and progressive systemic, metastatic disease will be recruited. Clinicians will screen patients against inclusion criteria to determine eligibility. All men enrolled will be prescribed a tailored, home-based, moderate-intensity exercise intervention consisting of aerobic and strengthening components for 12 weeks. Patients will receive supplementary education materials and weekly behavioural change consultations throughout the intervention. The primary outcome will be the feasibility of delivering such an intervention in men with metastatic disease. Secondary endpoints including skeletal events will be monitored for safety, as will the feasibility of patient-reported outcome measures and the sampling time points, generating data pertaining to completion rates and potential effect in future trials. General physical fitness will be assessed during these visits, using timed sit-to-stand testing and a 6-min walking test. Prior to each visit, objective physical activity levels will be captured for 7 days using an accelerometer, to determine the feasibility of this technology and the quality of data obtained. In parallel with the feasibility aspects of the trial, changes compared to baseline will be reported. Direct regular contact will also serve as a feedback loop, should any issues arise. This study has received ethical approval from the Office for Research Ethics Committees Northern Ireland.

CONCLUSIONS

This study aims to determine the potential utility of a home-based exercise intervention in managing side effects associated with advanced prostate cancer and its treatment. This feasibility trial will inform the design and implementation of a larger randomised control trial to determine the efficacy of moderate aerobic and strengthening exercise as an adjuvant therapy in men with metastatic prostate cancer. Collecting such evidence provides further support for exercise in this paradigm and potential for its inclusion as a low-toxicity therapy in standard cancer care, in the longer term.
