Effects of resistance exercise in prostate cancer patients: a meta-analysis

Cardio-oncology rehabilitation and exercise: evidence, priorities, and research standards from the ICOS-CORE working group

The aim of this whitepaper is to review the current state of the literature on the effects of cardio-oncology rehabilitation and exercise (CORE) programmes and provide a roadmap for improving the evidence-based to support the implementation of CORE. There is an urgent need to reinforce and extend the evidence informing the cardiovascular care of cancer survivors. CORE is an attractive model that is potentially scalable to improve the cardiovascular health of cancer survivors as it leverages many of the existing frameworks developed through decades of delivery of cardiac rehabilitation. However, there are several challenges within this burgeoning field, including limited evidence of the efficacy of this approach in patients with cancer. In this paper, a multidisciplinary team of international experts highlights priorities for future research in this field and recommends standards for the conduct of research.

The Effect of Resistance and/or Aerobic Training on Quality of Life, Fitness, and Body Composition in Prostate Cancer Patients-A Systematic Review and Meta-Analysis

Background: Prostate cancer (PC) and its treatment are often associated with side effects such as fatigue, muscle loss, and diminished quality of life (QoL). Physical exercise, particularly resistance training (RT) and aerobic training (AT), has been suggested as a strategy to mitigate these effects. However, the comparative efficacy of RT, AT, and combined RT/AT on QoL, body composition, physical fitness, and laboratory markers in PC patients is still insufficiently understood. Methods: Randomized controlled trials (RCTs) investigating structured RT, AT, or combined RT/AT programs in PC patients undergoing various treatments were included. The primary outcome was QoL, assessed using EORTC QLQ-C30 and EORTC QLQ-PR25 questionnaires. Secondary outcomes included body composition, fitness, and laboratory parameters. The studies were sourced from PubMed, Embase, and CENTRAL through May 2024. The effect sizes were pooled using random-effects models, and the risk of bias was systematically assessed following the GRADE approach. Results: A total of 30 RCTs, encompassing 2216 PC patients, were analyzed. Combined RT/AT significantly improved QoL subdomains, including global health, and cognitive and sexual function, while reducing fatigue and urinary symptoms. RT alone improved body composition by increasing lean body mass and reducing body fat percentage. Both RT and combined RT/AT enhanced strength (chest and leg press) and VO2peak. No significant changes were observed in laboratory markers, such as PSA or lipid levels. The effects of isolated AT remain unclear due to limited data. Conclusions: RT and combined RT/AT significantly improve QoL, fitness, and body composition in PC patients, with no detectable effect on PSA or lipid levels. Further research is needed to elucidate the specific effects of AT and to investigate long-term outcomes.

Voluntary Exercise Attenuates Tumor Growth in a Preclinical Model of Castration-Resistant Prostate Cancer

Purpose

To examine the effects of voluntary exercise training on tumor growth and explore the underlying intratumoral molecular pathways and processes responsible for the beneficial effects of VWR on tumor initiation and progression in a mouse model of Castration-Resistant Prostate Cancer (CRPC).

Methods

Male immunodeficient mice (SCID) were castrated and subcutaneously inoculated with human CWR-22RV1 cancer cells to construct CRPC xenograft model before randomly assigned to either voluntary wheel running (VWR) or sedentary (SED) group (n=6/group). After three weeks, tumor tissues were collected. Tumor size was measured and calculated. mRNA expression of markers of DNA replication, Androgen Receptor (AR) signaling, and mitochondrial dynamics was determined by RT-PCR. Protein expression of mitochondrial content and dynamics was determined by western blotting. Finally, RNA-sequencing analysis was performed in the tumor tissues.

Results

Voluntary wheel running resulted in smaller tumor volume at the initial stage and attenuated tumor progression throughout the time course (P < 0.05). The reduction of tumor volume in VWR group was coincided with lower mRNA expression of DNA replication markers ( MCM2 , MCM6 , and MCM7 ), AR signaling ( ELOVL5 and FKBP5 ) and regulatory proteins of mitochondrial fission (Drp1 and Fis1) and fusion (MFN1 and OPA1) when compared to the SED group (P<0.05). More importantly, RNA sequencing data further revealed that pathways related to pathways related to angiogenesis, extracellular matrix formation and endothelial cell proliferation were downregulated.

Conclusions

Three weeks of VWR was effective in delaying tumor initiation and progression, which coincided with reduced transcription of DNA replication, AR signaling targets and mitochondrial dynamics. We further identified reduced molecular pathways/processes related to angiogenesis that may be responsible for the delayed tumor initiation and progression by VWR.

Lifestyle and risk factors associated with elevated prostate-specific antigen levels in rural men: implications for health counseling

Background

The use of prostate-specific antigen (PSA) for early detection of prostate cancer (PCa) is common but controversial. In rural areas, PSA is widely used for screening because it is convenient and early-stage PCa often shows no symptoms. Studies suggest that PSA levels are linked to factors like unhealthy lifestyles, obesity, lack of exercise, inflammation, and aging. Proper use and interpretation of PSA are crucial for healthcare providers, especially in primary care settings. This study aims to explore the prevalence and factors linked to higher PSA levels in rural men.

Methods

We conducted a community-based cross-sectional study from March to December 2023 in the western coastal region of Taiwan. Men aged 40-75 years participated, completing a lifestyle questionnaire and providing blood samples for cardiometabolic biomarkers and PSA levels. PSA levels of ≥ 4.0 ng/mL were considered elevated. We used propensity score matching (PSM) and genetic matching (GM) for analysis, followed by regression analysis.

Results

In total, 3347 male adults with a mean age of 56.3 years (SD=11.8, range 40-75), and without cancer-related diseases, were enrolled. Findings indicated that 3.9% (n=130) of men aged 40-75 years had a PSA ≥ 4 ng/mL. and many of them did not adopt health-related behaviors, including inadequate servings of vegetables, water intake, and engaging in regular exercise. Furthermore, more than half of the participants had high blood pressure, and over one-quarter exhibited a higher waist-hip ratio and cardiometabolic diseases. After employing propensity score matching (PSM) and genetic matching (GM) with respect to age and education, the multivariate logistic regression model indicated that less water intake (p<0.01), higher waist-hip ratio (> 0.95) (p<0.05), and being diagnosed with cardiometabolic diseases (p<0.05) were significantly associated with a higher serum PSA level.

Conclusion

This study revealed that inadequate water intake and obesity related diseases are significant risk factors associated with elevated PSA levels among male adults living in rural areas. It is important for frontline healthcare providers to carefully interpret the meaning of a high PSA level. Additionally, launching a longitudinal study is necessary to further investigate its relation to PCa.

Resistance Exercise and Skeletal Muscle-Related Outcomes in Patients with Cancer: A Systematic Review

BACKGROUND

Skeletal muscle loss is prevalent throughout the cancer continuum and correlated with morbidity and mortality. Resistance exercise has been trialed to mitigate skeletal muscle loss. This systematic review summarizes and qualitatively synthesizes the effects of resistance exercise on muscle-related outcomes in adult cancer populations, including skeletal muscle mass, performance and muscle-related biomarkers.

METHODS

The systematic review protocol was developed in accordance with the Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols (PRISMA-P). We searched electronic databases including AMED, CENTRAL, CINAHL, CIRRIE, EMBASE, MEDLINE, PEDro, REHABDATA, Scopus, and SPORTDiscus from inception to December 2021. We included randomized controlled trials that investigated the effects of resistance exercise on muscle-related outcomes in adult cancer populations. Interventions that involved any resistance exercise were included. Muscle-related outcomes were categorized as skeletal muscle mass (e.g., lean mass, appendicular muscle mass), muscle performance (e.g., muscle strength, physical function), and muscle-related biomarkers (e.g., muscle cells, metabolic/inflammatory markers). Risk of bias (RoB) was assessed using the Cochrane ROB tool.

RESULTS

A total of 102 studies from 101 randomized controlled trials were included. The majority of studies focused on breast cancer (46%) and those who completed treatment (43%). Resistance exercise interventions were largely 3-4 months long (48%), combined with aerobic exercise (56%), at a vigorous intensity (25%), and in-person/supervised settings (57%). Among the studies assessing muscle mass, performance, and biomarkers ( n = 42, 83, and 22, respectively), resistance exercise interventions improved upper/lower body or appendicular muscle mass (67%-100%), muscle strength (61%-68%), and physical function (74%-100%). Most biomarkers did not show significant changes (75%-100%) or showed inconsistent results.

CONCLUSIONS

Generally, resistance exercise had positive effects on skeletal muscle mass and performance with no negative effects compared to controls. Our findings demonstrated that resistance exercise may be an effective strategy to attenuate deterioration or exert improvements in muscle mass and performance outcomes.

Inclusivity in prostate cancer and exercise research: a systematic review

BACKGROUND

Prostate cancer (PCa) is the most prevalent type of cancer in men in the UK. Exercise has been shown to improve the health and quality of life of PCa patients. Exercise should be easily accessible to men with PCa regardless of socioeconomic group or ethnicity. There is a need to better understand whether the current evidence base for exercise interventions is representative and inclusive of racial and ethnic minority men with PCa.

METHODS

A systematic review of the literature was conducted according to PRISMA guidelines and prospectively registered via Prospero (ID: CRD42022384373). The MEDLINE Ovid, Cochrane Library and PubMed databases were searched from inception to December 2022. The search strategy keywords and MeSH terms used included the following: (1) exercise, (2) training, (3) prostate cancer, (4) ethnic and (5) diversity.

RESULTS

A total of 778 records were retrieved from database searches, of which 15 records were duplicates. A further 649 were eliminated following the screening of titles and abstracts. After full-text screening of 186 articles, 28 manuscripts were included for review.

CONCLUSION

This systematic review highlights that there is high heterogeneity in the reporting of participants' ethnicity and there are low numbers of ethnic minority men included in PCa and exercise studies in the UK. Further work is required to understand why representation is lacking within PCa exercise trials in the UK and strategies are needed to achieve representation from all ethnic groups.

IMPLICATIONS FOR CANCER SURVIVORS

Improved representation and reporting of ethnicity in exercise trials is vital to ensure the results are applicable to all patients.

Effects of exercise during active surveillance for prostate cancer: A systematic review and meta-analysis

PURPOSE

The efficacy of exercise in men with prostate cancer (PCa) on active surveillance (AS) remains unclear. In this meta-analysis, we aimed to examine the effects of exercise in PCa patients on AS.

METHODS

A literature search was conducted in PubMed, EMBASE, and the Cochrane Library using search terms, including exercise, PCa, AS, and randomized controlled trials (RCTs). The means and standard deviations for peak oxygen consumption (VO2peak), prostate-specific antigen (PSA) levels, and quality of life (QoL) were extracted for the intervention and control groups. A random-effects model was used to summarize the effects of exercise.

RESULTS

Of the 158 identified studies, six RCTs with 332 patients were included. The interventions included lifestyle modifications (aerobic exercise + diet) in three studies and different exercise modalities in three studies. The intervention duration was 2-12 months; three interventions were supervised and three were self-directed. The pooled weighted mean difference between exercise and usual care for VO2peak was 1.42 mL/kg/min (95% confidence interval [CI]: 0.30 to 2.54, P ≤ 0.001). A non-significant effect was observed for QoL (pooled standardized mean difference [SMD]: 0.24, 95% CI: - 0.03 to 0.51, P = 0.08) which became statistically significant and stronger after excluding one outlier study (P < 0.001). Exercise also had a positive effect on PSA levels (pooled SMD: - 0.43, 95% CI: - 0.87 to 0.01, P = 0.05).

CONCLUSION

Exercise improves cardiorespiratory fitness and may improve QoL and PSA levels in men with PCa on AS. Further studies with larger sample sizes are warranted to obtain more reliable results.

Case studies on psychosocial factors that help make exercise programmes for prostate cancer patients self-sustaining

OBJECTIVES

Patients with prostate cancer (PCa) benefit from regular exercise, but it is difficult for patients to maintain an exercise regime. We examined two exercise programmes that have proven to be self-sustaining with the goal of identifying features they share that may contribute to their success.

METHODS

We compared the FC Prostata football (soccer) league in Denmark and the 'Butts in a Boat' (BIAB) dragon-boating team in Canada. The FC Prostata Project Coordinator and the BIAB team leaders provided information on their programmes' history and structure.

RESULTS

Both programmes are team-based with regularly scheduled intense exercise at their core. In both cases, social activities evolved spontaneously, starting with the men going out for food and/or drinks after practices. The sustainability of these programmes may be driven by the regular socialisation linked to the fitness activities.

CONCLUSIONS

Our case studies suggest that exercise programmes for PCa patients may have a good chance of being self-sustaining, if they are: (1) centred around intense exercise, (2) of a team nature, (3) structured to promote egalitarianism and avoid one-on-one competition within teams, yet (4) have some competitions between teams. The data suggest that informal social activities organised by patients after team practices may be important for building fellowship and strengthening patients' commitment to exercise both for themselves and for their team members.

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

BACKGROUND

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

OBJECTIVE

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

METHODS

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

RESULTS

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

CONCLUSION

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

IMPLICATIONS FOR PRACTICE

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

Prostate cancer patients' experiences and preferences for web-based physical activity applications: A qualitative meta-synthesis

BACKGROUND

The incidence of prostate cancer increases with age. Physical activity can improve the prognosis and quality of life of patients. However, studies have observed lower levels of physical activity in men with prostate cancer, and most do not meet physical activity guidelines. Web-based physical activity is a promising form of exercise that will play an important role in prostate cancer patients.

AIMS

To synthesise the experiences and preferences of prostate cancer patients for web-based PA applications, thereby providing a basis for the construction of intervention programs tailored to the needs of patients.

METHODS

We systematically searched PubMed, Web of Science, Cochrane Library, EMBASE, CINAHL and three Chinese databases. This review includes qualitative empirical reports from the date of establishment of the respective databases until April 2023. Data extraction was performed by two independent reviewers and study quality was assessed.

RESULTS

A total of nine studies were included. The experiences and preferences of prostate cancer patients with web-based physical activity apps were synthesised into the following three analysis themes: (1) Pursuing individualised management strategies; (2) Perceiving and seeking social support and (3) Moving forwards in the struggle.

CONCLUSION

Our study found that men with prostate cancer experienced greater challenges in engaging in physical activity. Because of individual differences between patients, health care providers need to provide care that is tailored to each patient. Future studies should further explore the specific effects of web-based PA applications in promoting the physical function of prostate cancer patients to increase their flexibility.

RELEVANCE TO CLINICAL PRACTICE

This article synthesises prostate cancer patients' experiences with web-based physical activity applications, highlighting their specific information needs. The results suggest several implications for the application of individualised management strategies, the perception and search for social support, and health- literacy. The results of this study will inform future research and program design that recognises the importance of patient-centred efforts to better self-manage physical function.

PATIENT OR PUBLIC CONTRIBUTION

In the early stages of the study, objectives and subsequent findings were presented and discussed in a meeting with a reference group that represented patients, health professionals and the public.

The Participation of Trans Women in Competitive Fencing and Implications on Fairness: A Physiological Perspective Narrative Review

Debate has surrounded whether the participation of trans women in female sporting categories is fair, specifically the retained male physiological advantage due to increased testosterone compared to cisgender females. Recently, individual sporting organisations have been investigating and assessing policies regarding trans women athlete participation in female categories, resulting in several banning participation. This review aims to discuss the scientific evidence and provide appropriate guidance for the inclusion of trans women in elite competitive female fencing categories. Fencing is an intermittent sport, where competitions can span 1 to 3 days. The lunge is the most common movement used to attack opponents, where a successful hit relies on the speed of the action. Male puberty induced increased circulating testosterone promotes a greater stature, cardiovascular function, muscle mass, and strength compared to cisgender females, culminating in a ~12-40% sport performance advantage. Elite cisgender male fencers perform significantly higher, ~17-30%, jump heights and leg power measures compared to elite cisgender female fencers, resulting in faster lunges. Trans women receiving androgen-suppression therapy for 12 months showed significant reductions in strength, lean body mass, and muscle surface area, but even after 36 months, the measurements of these three indices remained above those for cisgender females. Previous male muscle mass and strength can be retained through continuation of resistance training. The literature reviewed shows that there is a retained physiological advantage for trans women who have undergone male puberty when participating in the elite competitive female fencing category. A proposed solution of an open or third gender category for elite fencing competition promotes fair competition, while allowing trans women to compete in their chosen sport.

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.

Voluntarily wheel running inhibits the growth of CRPC xenograft by inhibiting HMGB1 in mice

INTRODUCTION

Exercise has been proved to reduce the risk of recurrence and mortality of cancer. Emerging evidence indicated that exercise may regulate both systematical and local metabolism, immunity and other ways. Although the role of exercise in inhibiting castration-resistant prostate cancer is well established, the underlying mechanism remains unclear.

METHOD

Twenty C57BL/6 male mice were used to construct CRPC xenograft models and randomly divided into exercise group (n = 10) and control group (n = 10). After exercised with voluntarily wheel running for 21 days, the mice were sacrificed and the tumor tissues and serum were collected. TUNEL staining was used to detect the apoptosis of tumor cells. The expression of PI3K signal pathway and apoptosis related proteins were detected by Western blot. The expression of AR and HMGB1 were examined by Western blot and Immunohistochemical staining. IFN-γ, TNF-α, TGF-β, IL-4, IL-6, IL-10 in serum was examined using ELISA kits.

RESULTS

Voluntarily wheel running inhibited the growth of CRPC xenografts, inhibited the proliferation of tumor cells and promoted the apoptosis of tumor cells. HMGB1 levels in serum and tumor tissues were significantly reduced after exercise, which enhanced local immunity by inducing more leukocyte infiltration and inhibited systemic inflammatory response by regulating cytokines.

CONCLUSION

Voluntary wheel running can down-regulate the expression of HMGB1 in serum and transplanted tumor tissues, inhibit proliferation and promote apoptosis of tumor cells, enhance immune cell infiltration and systemic inflammatory response, and regulate local anti-tumor effects in tumor microenvironment.

Associations of Age and Sex with the Efficacy of Inpatient Cancer Rehabilitation: Results from a Longitudinal Observational Study Using Electronic Patient-Reported Outcomes

Cancer rehabilitation is thought to increase the quality of life (QOL) and functioning of cancer survivors. It remains, however, uncertain whether subgroups benefit equally from rehabilitation. We wished to investigate the outcomes of multimodal rehabilitation according to age, sex and functioning. Patients of an Austrian rehabilitation center routinely completed the EORTC QLQ-C30 and the hospital anxiety and depression scale (HADS) questionnaires prior to (T1), and after rehabilitation (T2). To compare the outcomes between age groups (i.e., <40, 41–69, and ≥70 years), sex, and the Norton scale risk status, repeated measures of analyses of variance were calculated. A total of 5567 patients with an average age of 60.7 years were included, of which 62.7% were female. With T1 indicating the cancer survivors’ needs, older and high-risk patients reported lower functioning (all p < 0.001) and a higher symptom burden for most scales (all p < 0.05) before rehabilitation. Regardless of age, sex or risk status, the patients showed at a least small to medium improvement during rehabilitation for anxiety, depression, and most functioning and symptom scales. Some between-group differences were observed, none of which being of a relevant effect size as determined with the Cohen’s d. In conclusion, QOL is improved by rehabilitation in all patients groups, independently from age, sex, or the risk status.

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.

The Impact of Exercise on Improving Body Composition and PSA in High-Risk Prostate Cancer Patients on Androgen-Deprivation Therapy

This prospective study investigated how exercise impacted chronological changes in anthropometrics, body composition, prostate-specific antigen (PSA) level and prognostic nutrition index (PNI) in high-risk prostate cancer (PCa) patients on androgen deprivation therapy (ADT). The patients were divided into either the usual care or exercise group. All patients received measurements a week before ADT initiation, six- and twelve months after treatment. The exercise group received both aerobic and resistance training. The analysis was conducted using appropriate statistical methods. There were 45 males enrolled (age 67.4 ± 8 years and BMI 25.5 ± 3.6 kg/m²). Profound changes were observed at six months follow-up. The exercise group showed a significant increase in the trunk and leg lean mass, and a lesser loss of total and arm lean mass. A significant decrease in PSA was also observed among the exercise group. PNI and PSA were significantly associated with regional lean mass. Exercise can prevent loss or even increase lean mass in high-risk PCa, especially in the early stage of ADT treatment. Moreover, a strong bond between lean mass and PNI and PSA further underscores the importance of early and continuous exercise interventions.

The effects on type 2 diabetes mellitus mouse femoral bone achieved by anti-osteoporosis exercise interventions

Purpose

Exercise therapy and key regulators of bone quality exert anti-hyperglycemic effects on type 2 diabetes mellitus (T2DM) mice. A number of programs have been reported to have an effect on bone disease in T2DM. Major unanswered questions concern the potential correlation of exercise with the improvement of bone quality in T2DM mice and how the nonlinear optical properties of bone are correlated with changes to its crystal structure.

Methods

Subjects were randomly divided into six groups: 1) control (C) group, which was fed a normal diet (n = 8); 2) T2DM quiet group, which was given a high-fat diet and quiet (n = 8); 3) T2DM plus swimming (T2DM+S) group, which received T2DM and swim training (n = 8); 4) T2DM plus resistance exercise (T2DM+RE) group, which was given T2DM and resistance exercise (n = 8); 5) T2DM plus aerobic exercise (T2DM+AE) group, with T2DM and medium-intensity treadmill exercise (n = 8); and 6) T2DM plus high-intensity interval training (T2DM+HIIT), with T2DM and high-intensity variable-speed intervention (n = 8). The levels of runt-related transcription factor 2 (RUNX2), osterix (OSX), and alkaline phosphatase (ALP), as well as the bone microstructure and morphometry, were measured at the end of the 8-week exercise intervention.

Results

Compared with the C group, the bone microstructure indexes [bone mineral density (BMD), bone volume/tissue volume (BV/TV), cortical thickness (Ct.Th), and connectivity density (Conn.D)], the bone biomechanical properties (maximum load, fracture load, yield stress, and elastic modulus), and the osteogenic differentiation factors (RUNX2, OSX, and BMP2) of the T2DM group were significantly decreased (all p < 0.05). Compared with the T2DM group, there were obvious improvements in the osteogenic differentiation factor (OSX) and Th.N, while the separation of trabecular bone (Tb.Sp) decreased in the T2DM+AE and T2DM+HIIT groups (all p < 0.05). In addition, the bone microstructure indicators BV/TV, tissue mineral density (TMD), Conn.D, and degree of anisotropy (DA) also increased in the T2DM+HIIT group, but the yield stress and Ct.Th deteriorated compared with the T2DM group (all p < 0.05). Compared with the T2DM+S and T2DM+RE groups, the BV/TV, trabecular number (Tb.N), Tb.Sp, and Conn.D in the T2DM+AE and T2DM+HIIT groups were significantly improved, but no significant changes in the above indicators were found between the T2DM+S and T2DM+RE groups (all p < 0.05). In addition, the BMD and the expression of ALP in the T2DM+AE group were significantly higher than those in the T2DM+HIIT group (all p < 0.05).

Conclusion

There was a significant deterioration in femur bone mass, trabecular bone microarchitecture, cortical bone geometry, and bone mechanical strength in diabetic mice. However, such deterioration was obviously attenuated in diabetic mice given aerobic and high-intensity interval training, which would be induced mainly by suppressing the development of T2DM. Regular physical exercise may be an effective strategy for the prevention of not only the development of diabetes but also the deterioration of bone properties in patients with chronic T2DM.

Telehealth exercise to Improve Physical function and frailty in patients with multiple myeloma treated with autologous hematopoietic Stem cell transplantation (TIPS): protocol of a randomized controlled trial

BACKGROUND

Advances in autologous hematopoietic stem cell transplantation (HSCT) and supportive care have led to marked improvements in survival for patients with multiple myeloma. Despite these improvements, patients with multiple myeloma remain at high risk of physical dysfunction and frailty due to HSCT and its associated exposures. Although traditional supervised exercise programs can improve frailty in cancer patients and survivors, rehabilitation facilities are typically far from a patient's residence, are offered on fixed days/hours, contain uniform activities for everyone, and carry a higher risk of contact cross-infection due to immunosuppression, which can be barriers to exercise participation. Innovative personalized interventions are needed to overcome the limitations of traditional exercise interventions. The purpose of this study is to determine the efficacy and sustainability of a telehealth exercise intervention on physical function and frailty in patients with multiple myeloma treated with HSCT.

METHODS

This randomized controlled trial will assess the efficacy of an 8-week telehealth exercise intervention in 60 patients with multiple myeloma who underwent autologous HSCT (30-180 days post-transplant) and are pre-frail or frail. There will be 30 intervention participants and 30 delayed controls. We will administer remote baseline assessments (week 0), followed by an 8-week telehealth intervention (week 1-8), post assessment (week 9), and an additional follow-up assessment (week 17). Our primary endpoint will be improved physical function, as assessed by the Short Physical Performance Battery test. Our secondary endpoint will be a decrease in frailty characteristics such as gait speed, strength, and fatigue. We will also evaluate the sustainability of improved physical function and frailty at week 17. Participants randomized to the intervention group will perform at least 90 min of exercise per week throughout the 8 weeks.

DISCUSSION

This study will help optimize the delivery of safe, low-cost, and scalable telehealth exercise interventions to improve health outcomes in patients with multiple myeloma, an understudied population at high risk for physical dysfunction and frailty. Our study may provide the foundation for sustainable telehealth exercise interventions to improve physical function and frailty for other hematologic cancer patients (e.g., acute leukemia, lymphoma) as well as any other cancer population of interest.

Effectiveness of combined nutrition and exercise interventions on body weight, lean mass, and fat mass in adults diagnosed with cancer: a systematic review and meta-analysis

CONTEXT

Changes in body weight and composition (fat and lean mass) are prominent side effects of cancer treatment. Nutrition and exercise interventions are both key strategies to protect against these adverse effects, yet their impact when combined has not been comprehensively reviewed in adults with cancer.

OBJECTIVE

This systematic review and meta-analysis aims to assess the effects of combined nutrition and exercise interventions on body weight and composition in adults with cancer.

DATA SOURCES

Four databases were searched until January 2021. Combined nutrition and exercise randomized controlled trials that detailed the nutrition and exercise prescription and reported body weight and composition outcomes were eligible.

DATA EXTRACTION

Risk of bias was assessed through the Cochrane Collaboration tool. The number of participants, mean values, and standard deviations of the outcome variables were extracted. Mean differences (MDs) were pooled using random-effects models. Predetermined subgroup analyses included cancer type, intervention intent, exercise modality, and use of behavior change strategies.

DATA ANALYSIS

Twenty-three RCTs were included. Nutrition plus exercise interventions significantly reduced body weight (MD -  2.13 kg; 95%CI, - 3.07 to - 1.19), fat mass (MD - 2.06 kg; 95%CI, - 3.02 to - 1.09), and lean mass (MD - 0.43; 95%CI, - 0.82 to - 0.04). Subgroup analyses in women with breast cancer showed that weight loss interventions and interventions incorporating behavior change strategies significantly reduced body weight and fat mass but also reduced lean mass. Interventions aiming to maintain body weight showed no changes in body weight, as intended.

CONCLUSION

Combined nutrition and exercise interventions successfully reduce body weight and fat mass in adults with cancer but also reduce lean mass. In contrast, weight loss-focused interventions are associated mostly with reduced lean mass.

Supervised exercise therapy compared with no exercise therapy to reverse debilitating effects of androgen deprivation therapy in patients with prostate cancer: a systematic review and meta-analysis

BACKGROUND

Androgen deprivation therapy (ADT) in patients with prostate cancer can have several debilitating side effects. Supervised exercise is recommended to ameliorate these negative effects.

OBJECTIVE

To systematically evaluate the effect of supervised exercise therapy compared to no exercise therapy in patients with prostate cancer undergoing ADT, primarily according to the patient critical outcomes, 'disease-specific quality of life' and 'walking performance' measured at end of treatment.

METHODS

We searched PubMed/Medline, Embase, Cochrane Library, Cinahl and Pedro, to identify randomised controlled trials (RCTs), which investigated the effect of supervised exercise therapy compared to no exercise therapy in patients with prostate cancer receiving ADT, last search: June 2021. Two independent reviewers extracted data, and assessed risk of bias using Cochrane Risk of Bias Tool and evaluated the certainty of evidence using the GRADE-method.

RESULTS

Eigthteen RCTs (n = 1477) comprised patients with prostate cancer stages T1-T4 were included in the meta-analyses. Compared to no exercise therapy, supervised exercise therapy showed clinically relevant improvements in 'disease-specific quality of life' and 'walking performance'. The standardised mean differences were 0.43 (95% confidence interval (CI): 0.29, 0.58) and -0.41 (95% CI: -0.60, -0.22), respectively. The overall certainty of evidence was moderate due to serious risk of bias.

CONCLUSIONS

Evidence of moderate quality shows that supervised exercise therapy probably is superior to no exercise therapy in improving 'disease-specific quality of life' and 'walking performance' in patients with prostate cancer undergoing ADT. The results apply to all patients receiving androgen deprivation therapy regardless of cancer stage. The results support a strong recommendation for supervised exercise therapy for managing side effects in this population.

Does Androgen Deprivation for Prostate Cancer Affect Normal Adaptation to Resistance Exercise?

BACKGROUND

Loss of muscle mass and muscle function is a common side effect from androgen deprivation therapy (ADT) for prostate cancer (PCa). Here, we explored effects of heavy-load resistance training (RT) on lean body mass and muscle strength changes reported in randomized controlled trials (RCTs) among PCa patients on ADT and in healthy elderly men (HEM), by comparison of results in separate meta-analysis.

METHODS

RCTs were identified through databases and reference lists.

RESULTS

Seven RCTs in PCa patients (n = 449), and nine in HEM (n = 305) were included. The effects of RT in lean body mass change were similar among PCa patients (Standardized mean difference (SMD): 0.4, 95% CI: 0.2, 0.7) and HEM (SMD: 0.5, 95% CI: 0.2, 0.7). It is noteworthy that the within group changes showed different patterns in PCa patients (intervention: 0.2 kg; control: -0.6 kg) and HEM (intervention: 1.2 kg; control: 0.2 kg). The effects of RT on change in muscle strength (measured as 1 RM) were similar between PCa patients and HEM, both for lower body- (PCa: SMD: 1.9, 95% CI: 1.2, 2.5; HEM: SMD: 2.2, 95% CI: 1.0, 3.4), and for upper body exercises (PCa: SMD: 2.0, 95% CI: 1.3, 2.7; HEM: SMD: 1.9, 95% CI: 1.3, 2.6).

CONCLUSIONS

The effects of RT on lean body mass and 1 RM were similar in PCa patients on ADT and HEM, but the mechanism for the intervention effect might differ between groups. It seems that RT counteracts loss of lean body mass during ADT in PCa patients, as opposed to increasing lean body mass in HEM.

The role of muscle depletion and visceral adiposity in HCC patients aged 65 and over undergoing TACE

Background

The incidence of hepatocellular carcinoma (HCC) has been increasing among the elderly populations. Trans-arterial chemoembolization (TACE), a widely used first-line non-curative therapy for HCCs is an issue in geriatrics. We investigated the prognosis of elderly HCC patients treated with TACE and determined the factors that affect the overall survival.

Methods

We included 266 patients who were older than 65 years and had received TACE as initial treatment for HCC. We analyzed the skeletal muscle index (SMI) and visceral-to-subcutaneous fat ratio (VSR) around the third lumbar vertebrae using computed tomography scans. Muscle depletion with visceral adiposity (MDVA) was defined by falling below the median SMI and above the median VSR value sex-specifically. We evaluated the overall survival in association with MDVA and other clinical factors.

Results

The mean age was 69.9 ± 4.5 years, and 70.3% of the patients were men. According to the Barcelona Clinic Liver Cancer (BCLC) staging system, 29, 136, and 101 patients were classified as BCLC 0, A, and B stages, respectively, and 79 (29.7%) had MDVA. During the median follow-up of 4.1 years, patients with MDVA had a shorter life expectancy than those without MDVA (P = 0.007) even though MDVA group had a higher objective response rate after the first TACE (82.3% vs. 75.9%, P = 0.035). Multivariate analysis revealed that MDVA (Hazard ratio [HR] 1.515) age (HR 1.057), liver function (HR 1.078), tumor size (HR 1.083), serum albumin level (HR 0.523), platelet count (HR 0.996), tumor stage (stage A, HR 1.711; stage B, HR 2.003), and treatment response after the first TACE treatment (HR 0.680) were associated with overall survival.

Conclusions

MDVA is a critical prognostic factor for predicting survival in the elderly patients with HCC who have undergone TACE.

Multimodal physical exercise and functional rehabilitation program in oncological patients with asthenia. study protocol

Background

The increase in the survival of oncology patients include multiple side effects as cancer-related asthenia and dyspnea, which represents a serious health problem. An implementation of the conventional clinical practice, developed through multimodal physical exercise and functional rehabilitation program intervention, may be useful in controlling dyspnoea. This study aims to evaluate the effects of a multimodal exercise and functional rehabilitation program on fatigue, pain, functional capacity, and quality of life in cancer patients with cancer-related asthenia.

Methods

This is a protocol for an experimental, prospective, randomised study using a parallel, fixed assignment scheme, with an experimental group and a control group in patients from the oncology hospitalisation unit at the Salamanca University Hospital Complex in Spain, using consecutive sampling to select 50 participants with oncological asthenia who are hospitalised at the time of inclusion. After the baseline evaluation, the participants will be randomised into two groups. Both groups will receive standard clinical practice care and the normal health education program at discharge, but in addition, the participants assigned to the experimental group will also complete a multimodal exercise and functional rehabilitation program lasting one month. The primary outcomes will be basic activities of daily living (Barthel Index) and degree of asthenia (FACT-An scale). Additionally, physical performance will be evaluated with the Short Physical Performance Battery (SPPB), as will the attention and executive functions (Trail-Making Test), fear/avoidance of movement (TAMPA scale), pain (VAS scale), and body composition (waist, hip, brachial, thigh, wrist, and ankle circumferences).

Discussion

The results of this study may be translated to clinical practice, incorporating a specific autonomy recovery programme into comprehensive rehabilitation programmes of care for cancer patients with asthenia. The current study addresses to improve the conventional clinical practice by proposing a multimodal physical exercise and functional rehabilitation program intervention, which will be implemented by an interdisciplinary team, to try to improve the autonomy of cancer patients with cancer-related asthenia.

The Effect of Resistance Training on Body Composition During and After Cancer Treatment: A Systematic Review and Meta-Analysis

BACKGROUND

Changes in body composition during cancer treatments have been linked with poorer outcomes, and increased morbidity and mortality. The effect of resistance training (RT) on body composition in cancer cohorts is debated.

OBJECTIVE

We conducted a systematic review and meta-analysis to determine the effect of RT on body composition during and after treatment.

METHODS

We searched five electronic databases for articles up to 1 February 2021 and included randomized controlled trials that compared RT with a non-exercise control in adults with cancer. Risk of bias was assessed using the RoB 2 tool. Pairwise, random-effects meta-analysis was used to synthesize the available data.

RESULTS

Overall, we included 15 studies (n = 1368). After treatment (11 studies), RT increased lean mass with moderate heterogeneity {0.41 kg [95% confidence interval (CI) 0.05, 0.76], p = 0.029; I² = 47.1%, p = 0.02} and decreased fat mass with substantial heterogeneity (- 0.59 kg [95% CI - 1.05, - 0.12], p = 0.019; I² = 69.1%, p < 0.001). During treatment (4 studies), RT did not increase lean mass (0.71 kg [95% CI - 0.04, 1.45], p = 0.05; I² = 0.0%, p = 0.75) or reduce fat mass (0.00 kg [95% CI - 5.31, 5.30], p = 0.99; I² = 0.0%, p = 0.62), both with no heterogeneity.

CONCLUSION

Modest improvements in body composition were observed following RT after cancer treatment; however, no changes were observed during treatment. These adaptations are markedly lower than those observed in healthy cohorts but may be clinically meaningful for the cancer survivorship population. At present it is unclear if these diminished adaptations are due to ineffective exercise prescriptions in cancer cohorts or due to an innate anabolic resistance as a result of cancer and its treatments.

Impact of lifestyle in prostate cancer patients. What should we do?

Objective:

This review aimed to analyze interventions raised within primary and tertiary prevention concerning the disease's incidence, progression, and recurrence of Prostate Cancer (PCa). Priority was given to the multidisciplinary approach of PCa patients with an emphasis on modifiable risk factors.

Materials and Methods:

We conducted a comprehensive literature review in the following databases: Embase, Central, and Medline. We included the most recent evidence assessing cohort studies, case-control studies, clinical trials, and systematic reviews published in the last five years. We only included studies in adults and in vitro or cell culture studies. The review was limited to English and Spanish articles.

Results:

Preventive interventions at all levels are the cornerstone of adherence to disease treatment and progression avoidance. The relationship in terms of healthy lifestyles is related to greater survival. The risk of developing cancer is associated to different eating habits, determined by geographic variations, possibly related to different genetic susceptibilities.

Discussion:

PCa is the second most common cancer in men, representing a leading cause of death among men in Latin America. Prevention strategies and healthy lifestyles are associated with higher survival rates in PCa patients. Also, screening for anxiety and the presence of symptoms related to mood disorders is essential in the patient's follow-up concerning their perception of the condition.

Exercise-induced myokines and their effect on prostate cancer

Exercise is recognized by clinicians in the field of clinical oncology for its potential role in reducing the risk of certain cancers and in reducing the risk of disease recurrence and progression; yet, the underlying mechanisms behind this reduction in risk are not fully understood. Studies applying post-exercise blood serum directly to various types of cancer cell lines provide insight that exercise might have a role in inhibiting cancer growth via altered soluble and cell-free blood contents. Myokines, which are cytokines produced by muscle and secreted into the bloodstream, might offer multiple benefits to cellular metabolism (such as a reduction in insulin resistance, improved glucose uptake and reduced adiposity), and blood myokine levels can be altered with exercise. Alterations in the levels of myokines such as IL-6, IL-15, IL-10, irisin, secreted protein acidic risk in cysteine (SPARC), myostatin, oncostatin M and decorin might exert a direct inhibitory effect on cancer growth via inhibiting proliferation, promoting apoptosis, inducing cell-cycle arrest and inhibiting the epithermal transition to mesenchymal cells. The association of insulin resistance, hyperinsulinaemia and hyperlipidaemia with obesity can create a tumour-favourable environment; exercise-induced myokines can manipulate this environment by regulating adipose tissue and adipocytes. Exercise-induced myokines also have a critical role in increasing cytotoxicity and the infiltration of immune cells into the tumour.

High-intensity interval training or resistance training versus usual care in men with prostate cancer on active surveillance: A three-arm feasibility randomized controlled trial

BACKGROUND

This study assessed the feasibility of a phase II randomized controlled trial of high-intensity interval training (HIIT), resistance training (RT), and usual care (UC) in men with prostate cancer (PCa) on active surveillance (AS) and evaluated changes in clinically relevant outcomes.

METHODS

Eighteen men undergoing AS for PCa were randomized to HIIT (n=5), RT (n=7), or UC (n=6). Exercise participants attended two supervised sessions weekly and were instructed to complete one home-based session weekly for 8 weeks. UC participants were provided with physical activity guidelines.

RESULTS

Feasibility was met for attendance, compliance, and retention, but not recruitment. HIIT increased leg press (mean: +8.2kg, 95%CI 1.1, 15.3) from baseline to 8 weeks. RT increased seated row (mean: +11.7kg, 95%CI 6.1, 17.3) and chest press (mean: +10.4kg, 95%CI 5.3, 15.5), leg press (mean: +13.1kg, 95%CI 5.9, 20.3), serum insulin-like binding protein-3 (IGFBP-3) (mean: +400.0ng/ml, 95%CI 94.5, 705.5), and decreased interferon-γ (mean: -3.1pg/ml, 95%CI -5.7, -0.4). No changes were observed in the UC group.

CONCLUSION

HIIT and RT may be effective strategies for improving muscle strength; however, only RT may increase serum IGFBP-3. Strategies that can enhance recruitment in men on AS are important prior to conducting a phase II trial.

What is the minimal dose for resistance exercise effectiveness in prostate cancer patients? Systematic review and meta-analysis on patient-reported outcomes

BACKGROUND

Active treatments for prostate cancer are well known to result in several adverse effects such as fatigue, depression and anxiety symptoms, impacting the overall quality of life (QoL) and wellbeing of a considerable proportion of patients. Resistance-based exercise interventions have shown positive effects to reduce or mitigate these treatment-related side effects. However, the minimal dosage required to derive these benefits is unknown. We systematically reviewed the resistance training effects in prostate cancer patients to determine the minimal dosage regarding the exercise components (mode, duration, volume and intensity) on fatigue, QoL, depression and anxiety.

METHODS

Using PRISMA guidelines, MEDLINE, CINAHL, EMBASE, SPORTDiscus and Web of Science databases were searched. Eligible randomised controlled trials examined prostate cancer patients undertaking resistance-based exercise programs during or following treatment. Meta-analysis was undertaken when more than three studies were included. Associations between resistance exercise components and its effects were tested by meta-regression analysis.

RESULTS

Eighteen trials involving 1112 men with prostate cancer were included. Resistance-based exercise programs resulted in significant effects on fatigue (effect size = -0.3, 95% CI: -0.4 to -0.2, P < 0.001) and QoL (effect size = 0.2, 95% CI: 0.0 to 0.4, P = 0.018), with significant effects in specific questionnaires and domains of these outcomes. Resistance-based exercise effects on depression (effect size = -0.3, 95% CI: -0.7 to 0.0) and anxiety symptoms (effect size = -0.3, 95% CI: -0.5 to 0.0) were positive but not significant (P = 0.071 to 0.077). Meta-regression indicated no significant association between resistance exercise components with fatigue and QoL outcomes (P = 0.186-0.689).

CONCLUSIONS

Low volume resistance exercise undertaken at a moderate-to-high intensity is sufficient to achieve significant fatigue and QoL benefits for men with prostate cancer and also mitigate depression and anxiety symptoms. A lower resistance exercise dosage than usually prescribed may help enhance adherence by reducing exercise barriers.

Muscle hypertrophy in cancer patients and survivors via strength training. A meta-analysis and meta-regression

BACKGROUND

Muscle wasting has a negative effect on treatment toxicity and cancer prognosis. Resistance training appears to be a promising approach to counteract the loss of muscle mass.

METHODS

Pubmed, Cochrane Library, SportDiscus and CINAHL. Randomized controlled resistance training trials with cancer survivros where eligible if lean body mass (LBM) or muscle mass were assessed.

RESULTS

A total of 34 trials were included into the primary analysis. Compared to the control individuals, the intervention groups show a superiority in LBM of 0.85 kg (95 % CI = 0.26-1.43, p = .004). Isolated, the participants in the intervention groups show an increase in LBM of 0.51 kg (95 % CI = -0.05-1.06, p = .072); the control groups displayed a decrease of -0.59 kg (95 % CI= -1.04 to 0.06, p = .078). Supervision displayed an mediating role.

CONCLUSIONS

Resistance training can counteract the loss of muscle mass in cancer patients. Especially in a supervised setting.

Skeletal Muscle-Adipose Tissue-Tumor Axis: Molecular Mechanisms Linking Exercise Training in Prostate Cancer

Increased visceral adiposity may influence the development of prostate cancer (PCa) aggressive tumors and cancer mortality. White adipose tissue (WAT), usually referred to as periprostatic adipose tissue (PPAT), surrounds the prostatic gland and has emerged as a potential mediator of the tumor microenvironment. Exercise training (ET) induces several adaptations in both skeletal muscle and WAT. Some of these effects are mediated by ET-induced synthesis and secretion of several proteins, known as myo- and adipokines. Together, myokines and adipokines may act in an endocrine-like manner to favor communication between skeletal muscle and WAT, as they may work together to improve whole-body metabolic health. This crosstalk may constitute a potential mechanism by which ET exerts its beneficial role in the prevention and treatment of PCa-related disorders; however, this has not yet been explored. Therefore, we reviewed the current evidence on the effects of skeletal muscle–WAT–tumor crosstalk in PCa, and the potential mediators of this process to provide a better understanding of underlying ET-related mechanisms in cancer.

Physical exercise for bone health in men with prostate cancer receiving androgen deprivation therapy: a systematic review

PURPOSE

Androgen deprivation therapy (ADT) is a treatment used in men with prostate cancer (PCa); however it is responsible for many adverse effects, with negative impact on quality of life. ADT causes loss of bone mineral density (BMD) and skeletal muscle mass, alteration of body composition, and cognitive function, which altogether lead to increased risk of accidental falls and fractures. This systematic review analyses the effectiveness of physical exercise (PE) in preventing accidental falls and fractures and reducing the loss of BMD in men with PCa receiving ADT.

METHODS

We searched MEDLINE, EMBASE, CINAHL, and the Cochrane Library for articles between database inception and September 2, 2020. Eligible studies included randomized controlled trials (RCTs) investigating the effects of exercise on bone health in men with PCa receiving ADT.

RESULTS

Nine RCTs were included. Experimental PE consisted in multicomponent programmes that involved aerobic, resistance, impact-loading exercise, and football training. None of the RCTs investigated the risk of accidental falls and fractures, while two trials reported beneficial effects of PE on lumbar spine, hip, and femoral shaft BMD. No further significant difference was detected in the outcomes investigated.

CONCLUSION

Evidence of the effectiveness of PE to prevent the risk of accidental falls and fractures and BMD loss is lacking. Nevertheless, clinical guidelines recommend PE as a part of the clinical management of men with PCa receiving ADT due to its known numerous health benefits. Research should focus on PE strategies to prevent accidental falls, a clinically relevant outcome in this vulnerable population.

Physical exercise and quality of life in patients with prostate cancer: systematic review and meta-analysis

BACKGROUND

Prostate cancer leads to worse quality of life due to treatment and consequences of disease; benefits of physical exercise remain unclear on the improvement of quality of life in this population. The aim of this study is to evaluate the effectiveness of physical exercise in improving quality of life in patients with prostate cancer.

METHODS

A systematic review and meta-analysis was carried out. For the search of studies, we used electronics databases such as Cochrane Library, MEDLINE via PUBMED, Regional Health Portal, and EMBASE, without language restrictions or year of publication. The descriptors used were as follows: "prostatic neoplasms," "exercise," and "quality of life." The risk analysis of bias in the meta-analysis was based on the Cochrane Collaboration Tool. For statistical analysis, the fixed effects model was used. Randomized controlled trials were included, which had a sample of patients with stage I-IV prostate cancer and that the intervention was aerobic physical exercise (AE) or resistance physical exercise (RE) or combined AE and RE.

RESULTS

Five thousand six hundred nineteen studies were identified, but only 12 studies were selected. The quality of life of the patients was measured using instruments (SF 36, EORTC, AQoL-8D, IPSS and FACT-P), which served to divide the studies in groups where they presented the same instrument used. The analysis carried out shows that the quality of life of patients with prostate cancer submitted to aerobic training regimens had a protective effect in relation to the others.

CONCLUSION

Most studies show an improvement in the quality of life of patients when they practice physical exercise, perceived by increasing the score of the instrument in question. However, methodological and heterogeneous differences between the studies increase the analysis bias.

Resistance Exercise Dosage in Men with Prostate Cancer: Systematic Review, Meta-analysis, and Meta-regression

PURPOSE

Resistance exercise improves an array of treatment-related adverse effects in men with prostate cancer; however, the minimal dosage required is unknown. We systematically reviewed the resistance training effects in prostate cancer patients to determine the minimal dosage regarding the exercise components (type, duration, volume, and intensity) on body composition, physical function, muscle strength, cardiorespiratory fitness, body mass index, and prostate-specific antigen.

METHODS

Using PRISMA guidelines, MEDLINE, CINAHL, EMBASE, SPORTDiscus, and Web of Science databases were searched. Eligible randomized controlled trials examined prostate cancer patients undertaking resistance-based exercise programs during or after treatment. Meta-analysis was undertaken when more than three studies were included. Associations between mean differences and exercise components were tested by univariate and multivariate meta-regression analysis.

RESULTS

Twenty-three articles describing 21 trials and involving 1748 prostate cancer patients were included. Exercise improved fat mass (-1% in body fat and -0.6 kg in fat mass), lean mass (~0.5 kg in lean and appendicular lean mass), functional capacity (i.e., chair rise, 400-m test, 6-m fast walk, and stair climb tests), and fitness outcomes (i.e., V̇O2peak and muscle strength) (P = 0.040-<0.001) with no change in body mass index or prostate-specific antigen (P = 0.440-0.735). Meta-regression indicated no association between exercise type, resistance training duration, weekly volume and intensity, and primary outcomes (P = 0.075-0.965). There was a significant association between exercise intensity and chest press muscle strength (favoring moderate intensity, P = 0.012), but not in other secondary outcomes.

CONCLUSION

In untrained older men with prostate cancer initiating an exercise program, lower volume at moderate to high intensity is as effective as higher volume resistance training for enhancing body composition, functional capacity, and muscle strength in the short term. A low exercise dosage may help reduce barriers to exercise and enhance adherence.

Resistance Exercise in Prostate Cancer Patients: a Short Review

Purpose of Review

The aim of this paper is to provide an overview of recent findings concerning the utilization of resistance exercise (RE) in prostate cancer (PCa), in particular as pertaining to the management of cancer therapy side effects.

Recent Findings

As of late, studies investigating the effects of RE in PCa patients have found positive effects on muscle strength, body composition, physical functioning, quality of life, and fatigue. The combination of RE and impact training appears to decrease the loss of bone mineral density. RE seems to be well accepted and tolerated, even by patients with bone metastatic disease, although a modification of the RE prescription is often necessary.

Summary

In PCa patients, RE has been well-researched and the data are clear that it is beneficial in multiple ways. Future directions should look at the long-term effects of RE, including mortality and relapse, as well as implementation of exercise programs.

High-intensity interval training in the prehabilitation of cancer patients-a systematic review and meta-analysis

PURPOSE

To evaluate the impact of high-intensity interval training (HIIT) on health-related outcome parameters in the prehabilitation of patients diagnosed with cancer.

METHODS

A systematic review and meta-analysis of comparative studies on HIIT in cancer prehabilitation conducted by screening standard databases from their inception to March 30, 2020. Outcomes of interest included cardiorespiratory fitness, feasibility, safety, clinical, and patient-reported outcomes.

RESULTS

Of the 855 identified studies, 8 articles met the inclusion criteria (7 randomized, 1 non-randomized controlled trial) with a total of 896 patients. The study protocols were heterogeneous, but the methodological quality ranged from good to high according to PEDro scale. Meta-analysis revealed a significant improvement of peak oxygen consumption (VO₂peak) achieved with HIIT compared to usual care. Furthermore, HIIT was feasible and safe, showing low risk of adverse events and positive effects on health-related outcomes in prehabilitative settings.

CONCLUSION

In the phase of prehabilitation, HIIT has potential health benefits in patients diagnosed with cancer and is feasible and safe to perform. Nonetheless, larger randomized controlled trials focusing on long-term effects (such as cancer recurrence or survival rates) are missing, to underline the potential relevance of HIIT for cancer patients.

Cost-Effectiveness Analysis of Supervised Exercise Training in Men with Prostate Cancer Previously Treated with Radiation Therapy and Androgen-Deprivation Therapy

BACKGROUND

Exercise for prostate cancer (PCa) survivors has been shown to be effective in addressing metabolic function and associated co-morbidities, as well as sarcopenia and significant functional impairment resulting from long-term androgen deprivation. Evidence on the cost-effectiveness of exercise interventions for PCa, however, is lacking, thus the aim of this study was to determine the cost-effectiveness of a supervised exercise intervention for long-term PCa survivors who previously received radiation therapy and androgen-deprivation therapy.

METHODS

Cost-effectiveness analysis from an Australian healthcare-payer perspective was conducted using patient-level data from a multicentre randomised controlled trial (RCT) of supervised exercise training (resistance and aerobic) compared to receiving printed exercise material and a recommendation to exercise in long-term PCa survivors (> 5 years post-diagnosis). Analysis was undertaken for the 6-month supervised exercise portion of the intervention, which involved 100 men aged between 62 and 85 years, 50 in each arm. The primary outcome was cost per quality-adjusted life-years (QALYs).

RESULTS

A 6-month supervised exercise intervention for PCa survivors resulted in an incremental cost-effectiveness ratio of AU$64,235 (2018 AUD) at an incremental cost of AU$546 per person and a QALY gain of 0.0085. At a willingness-to-pay of AU$50,000, the probability that the intervention is cost-effective was 41%. Sensitivity analysis showed that maintenance of benefits via a 6-month home-based intervention, immediately following the supervised intervention, lowered the cost per QALY gained to AU$32,051.

DISCUSSION

This is the first cost-effectiveness analysis of exercise for PCa survivors. The intervention was effective, but unlikely to be cost-effective at the generally accepted willingness-to-pay of AU$50,000 per QALY. It is likely that evidence to support cost savings from post-intervention outcomes would reveal greater benefits and contribute to a more comprehensive cost-effectiveness analysis. Future RCTs should incorporate longer follow-up durations and collection of data to support modelling to capture future health benefits. Measures of quality of life or utility more sensitive to the impact of physical activity would also improve future economic evaluations.

Effects of a structured exercise program on physical performance and function, quality of life and work ability of physically active breast cancer survivors : A retrospective data analysis

Background

Purpose of this retrospective data analysis was to depict the effects of a structured off-season conditioning program with breast cancer survivors competing in dragon boat paddling.

Methods

In this study 10 breast cancer survivors (mean age 52.0 ± 5.4 years) who had finished the primary cancer treatment and who were paddlers of the Vienna Pink Dragon self-help group underwent a structured 10-week exercise program as part of their routine supportive treatment. Upper extremity strength, endurance capacity, shoulder flexibility, quality of life and work ability were assessed at baseline and after completion of the exercise program.

Results

Out of 10 patients 8 completed more than 80% of the exercise sessions. A multivariate analysis of variance (MANOVA) of the pooled exercise effects showed a very large effect size (Η² = 0.982); however, the change from baseline to follow-up was non-significant (p = 0.363). In the European Organisation for Research and Treatment of Cancer Quality of Life of Cancer Patients Questionnaire (EORTC QLQ-C30) the exercise program led to a significant improvement of body image (p = 0.02) and less arm symptoms in the affected arm (p = 0.04).

Conclusion

A structured and well-planned exercise intervention program can have a large effect on the physical performance of pretrained breast cancer survivors. Moreover, it can increase the body image and decrease the arm symptoms in this population.

Biomarkers Associated With Tumor Ki67 and Cathepsin L Gene Expression in Prostate Cancer Patients Participating in a Presurgical Weight Loss Trial

Our previous presurgical weight loss trial among 40 prostate cancer patients found that rapid (but not slow) weight loss resulted in increased tumor Ki67 and Cathepsin L (CTSL) gene expression. In follow-up analyses, we strove to better understand these unexpected findings. A correlative study was undertaken by performing additional analyses [free fatty acids (FFAs), plasma CTSL, and inflammatory cytokines] on remaining pre-post intervention sera and exploring associations with extant data on tumor Ki67, body composition, physical activity (PA), and fecal microbiota. Positive associations were observed between changes in % body fat and FFAs (ρ = 0.428, p = 0.026), insulin (ρ = 0.432, p = 0.019), and Interleukin-6 (ρ = 0.411, p = 0.041). Change in Ki67 was inversely associated with change in lean mass (ρ = -0.912, p = 0.001) and change in insulin (ρ = -0.650, p = 0.042). Change in insulin was also associated with CTSL (ρ = -0.643, p = 0.024) and FFAs (ρ = -0.700, p = 0.016). Relative abundance of Bifidobacterium was associated with CTSL (ρ = 0.627, p = 0.039) and FFAs (ρ = 0.691, p = 0.019); Firmicutes was positively associated with change in PA (ρ = 0.830, p = 0.003). Contrary to hypotheses, FFAs decreased with systemic fat loss. Moreover, although glucose metabolism improved, it was inversely associated with Ki67 and CTSL. Lean mass loss was highly correlated with increased Ki67. The relationships between prostate tumor Ki67 and CTSL and weight loss associated changes in FFAs, lean mass, and fecal microbiota warrant further investigation.

Exercise and High-Fat Diet in Obesity: Functional Genomics Perspectives of Two Energy Homeostasis Pillars

The heavy impact of obesity on both the population general health and the economy makes clarifying the underlying mechanisms, identifying pharmacological targets, and developing efficient therapies for obesity of high importance. The main struggle facing obesity research is that the underlying mechanistic pathways are yet to be fully revealed. This limits both our understanding of pathogenesis and therapeutic progress toward treating the obesity epidemic. The current anti-obesity approaches are mainly a controlled diet and exercise which could have limitations. For instance, the “classical” anti-obesity approach of exercise might not be practical for patients suffering from disabilities that prevent them from routine exercise. Therefore, therapeutic alternatives are urgently required. Within this context, pharmacological agents could be relatively efficient in association to an adequate diet that remains the most efficient approach in such situation. Herein, we put a spotlight on potential therapeutic targets for obesity identified following differential genes expression-based studies aiming to find genes that are differentially expressed under diverse conditions depending on physical activity and diet (mainly high-fat), two key factors influencing obesity development and prognosis. Such functional genomics approaches contribute to elucidate the molecular mechanisms that both control obesity development and switch the genetic, biochemical, and metabolic pathways toward a specific energy balance phenotype. It is important to clarify that by “gene-related pathways”, we refer to genes, the corresponding proteins and their potential receptors, the enzymes and molecules within both the cells in the intercellular space, that are related to the activation, the regulation, or the inactivation of the gene or its corresponding protein or pathways. We believe that this emerging area of functional genomics-related exploration will not only lead to novel mechanisms but also new applications and implications along with a new generation of treatments for obesity and the related metabolic disorders especially with the modern advances in pharmacological drug targeting and functional genomics techniques.

Supervised Physical Rehabilitation in the Treatment of Patients with Advanced Cancer: a Systematic Review and Meta-analysis

BACKGROUND

As the survival rate of cancer patients increases, the clinical importance of rehabilitation provided by healthcare professionals also increases. However, the evidence supporting the relevance of rehabilitation programs is insufficient. This study aimed to review the literature on effectiveness in physical function, quality of life (QOL) or fatigue of supervised physical rehabilitation in patients with advanced cancer.

METHODS

A systematic review and meta-analysis was conducted following the Cochrane guidelines. We narratively described the results when meta-analysis was not applicable or appropriate. Literature databases including Ovid-MEDLINE, Ovid-EMBASE, and the Cochrane Library, as well as several Korean domestic databases, were searched up to June 2017 for studies that investigated the effectiveness of supervised physical rehabilitation programs on physical function, QOL or fatigue in patients with advanced cancer. The quality of the selected studies was evaluated independently by paired reviewers.

RESULTS

Eleven studies with 922 participants were finally selected among 2,459 articles. The meta-analysis revealed that after physical exercise, the physical activity level and strength of patients with advanced cancer increased significantly. The QOL showed a statistically significant improvement after physical rehabilitation according to the European Organization for Research and Treatment of Cancer version C30. Though some of measurements about cardiovascular endurance or strength in several studies were not able to be synthesized, each study reported that they were significantly improved after receiving rehabilitation.

CONCLUSION

Supervised physical rehabilitation for patients with advanced cancer is effective in improving physical activity, strength, and QOL. However, more trials are needed to prove the effectiveness of supervised exercise and to strengthen the evidence.

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.

Effects of resistance exercise in prostate cancer patients : A systematic review update as of March 2020

Purpose

The aim of this systematic review is to provide an update on the effects of resistance exercise (RE) in patients with prostate cancer (PCa), with special attention to the effects on sexual health.

Methods

A systematic search of the literature was conducted in March 2020 using the databases PubMed, MEDLINE, EMBASE, SCOPUS and the Cochrane Library. Only randomized, controlled trials published after 31 December 2016 were included in this update. Additionally, articles from current and previous reviews were utilized to provide a brief summary of the effects on sexual health.

Results

A total of 10 articles met the inclusion criteria, of which 5 were identified as independent studies. The remaining five articles presented additional data for studies, which have already been included. The identified studies further strengthened the evidence for positive effects on muscle strength, body composition and physical function. Positive effects on bone mineral density were apparent only when RE was combined with impact training. One article reported an improvement in fatigue and health-related quality of life. Only one study examined the effects of RE in isolation and three articles indicated positive effects of exercise on sexual health.

Conclusion

Recent evidence supports the use of RE in PCa patient rehabilitation as a countermeasure for treatment side effects. Further research is necessary to ascertain the optimal delivery methods and illuminate the effects on health-related quality of life (HRQOL), fatigue and sexual health.

Exercise and Nutritional Approaches to Combat Cancer-Related Bone and Muscle Loss

PURPOSE OF REVIEW

The aim of this narrative review is to summarise recent literature on the effects of exercise and nutrition interventions alone or in combination on muscle and bone loss in people with cancer.

RECENT FINDINGS

There is emerging evidence to support the inclusion of targeted exercise and nutrition strategies to counter loss of muscle and bone associated with cancer treatments. Although research in this field is advancing, the optimal exercise and nutrition prescription to combat cancer-related bone and muscle loss remain unknown. This review identifies specific components of nutrition and exercise interventions that are promising although require further exploration through studies designed to determine the effect on muscle and bone. A focused research effort is required to elucidate the full potential of exercise and nutrition intervention for people with cancer at risk of bone and muscle loss.

Resistance exercise and breast cancer-related lymphedema-a systematic review update and meta-analysis

BACKGROUND

The purpose of this systematic review update and meta-analysis was to analyze resistance exercise (RE) intervention trials in breast cancer survivors (BCS) regarding their effect on breast cancer-related lymphedema (BCRL) status and upper and lower extremity strength.

METHODS

Systematic literature search was conducted utilizing PubMed, MEDLINE, and Embase databases. Any exercise intervention studies-both randomized controlled and uncontrolled-which assessed the effects of RE on BCRL in BCS in at least one intervention group published between 1966 and 31st January 2020 were included. Included articles were analyzed regarding their level of evidence and their methodological quality using respective tools for randomized and nonrandomized trials of the Cochrane collaboration. Meta-analysis for bioimpedance spectroscopy (BIS) values as well as upper and lower extremity strength was conducted.

RESULTS

Altogether, 29 studies were included in the systematic review. Results of six studies with altogether twelve RE intervention groups could be pooled for meta-analysis of the BCRL. A significant reduction of BCRL after RE was seen in BIS values (95% CI - 1.10 [- 2.19, - 0.01] L-Dex score). Furthermore, strength results of six studies could be pooled and meta-analysis showed significant improvements of muscular strength in the upper and lower extremities (95% CI 8.96 [3.42, 14.51] kg and 95% CI 23.42 [11.95, 34.88] kg, respectively).

CONCLUSION

RE does not have a systematic negative effect on BCRL and, on the contrary, potentially decreases it.

Factors associated with exercise preferences, barriers and facilitators of prostate cancer survivors

OBJECTIVE

The purpose of this study was to understand the exercise levels, preferences and interests of prostate cancer survivors in Canada.

METHODS

An electronic survey was administered via a prostate cancer-specific website and assessed self-reported exercise levels, exercise preferences and interests, exercise barriers and facilitators to exercise.

RESULTS

Based on 103 participants, the majority (75.7%) of prostate cancer survivors did not meet both aerobic and resistance exercise guidelines, despite an interest in exercise. Strongest exercise preferences were shown for resistance exercise, walking, flexibility and bicycling and for performing exercise from a community-based gym or from home. Significant differences in exercise interests and facilitators were found between individuals who were meeting exercise guidelines compared to those who were not.

CONCLUSION

The majority of Canadian prostate cancer survivors are insufficiently active. Exercise preferences and facilitators appear to be influenced by current exercise levels. Resistance and aerobic exercise should be considered when programming exercise for prostate cancer survivors.

Supervised Physical Training Enhances Muscle Strength but Not Muscle Mass in Prostate Cancer Patients Undergoing Androgen Deprivation Therapy: A Systematic Review and Meta-Analysis

Introduction: Androgen deprivation therapy (ADT) is considered the basic treatment for advanced prostate cancer, but it is highly associated with detrimental changes in muscle mass and muscle strength. The aim of this meta-analysis was to investigate the effects of supervised physical training on lean mass and muscle strength in prostate cancer patients undergoing ADT.

Methods: A systematic literature search was performed using MEDLINE, Embase, and ScienceDirect until October 2018. Only studies that examined both muscle mass and strength in prostate cancer patients undergoing ADT were included. Outcomes of interest were changes in lean body mass (surrogate for muscle mass) as well as upper and lower body muscle strength. The meta-analysis was performed with fixed-effects models to calculate mean differences between intervention and no-training control groups.

Results: We identified 8,521 publications through the search of the following key words: prostate cancer, prostate tumor, prostate carcinoma, prostate neoplasm, exercise, and training. Out of these studies, seven randomized controlled trials met the inclusion criteria and where included in the analysis. No significant mean differences for changes in lean mass were observed between the intervention and control groups (0.49 kg, 95% CI: −0.76, 1.74; P = 0.44). In contrast, the mean difference for muscle strength was significant both in chest (3.15 kg, 95% CI: 2.46, 3.83; P < 0.001) and in leg press (27.46 kg, 95% CI: 15.05, 39.87; p < 0.001).

Conclusion: This meta-analysis provides evidence that low- to moderate-intensity resistance and aerobic training is effective for increasing muscle strength but may not be sufficient to affect muscle mass in prostate cancer patients undergoing ADT. The underlying mechanisms for this maladaptation may in part be explained by an insufficient stimulus induced by the training regimens as well as a delayed initiation of training in relation to the start of ADT. When interpreting the present findings, one should bear in mind that the overall number of studies included in this review was rather low, emphasizing the need for further studies in this field.

Typical aspects in the rehabilitation of cancer patients suffering from metastatic bone disease or multiple myeloma

Background

The aim of this study was to present a practical concept focusing on typical aspects of regular physical activity, exercise and physical modalities for patients suffering from metastatic bone disease or multiple myeloma.

Methods

A narrative review of the relevant scientific literature and presentation of clinical experiences.

Results

In cancer patients with metastatic bone disease or multiple myeloma, pain is treated in an interdisciplinary and multimodal setting by using medication, radiotherapy and physical medical modalities (e.g. transcutaneous electrical nerve stimulation); however, modalities increasing local blood flow, such as ultrasound therapy, thermotherapy, massage, various electrotherapy options, are not performed at the site of the tumor. For physical activity and exercise, a suitable indication of the static and dynamic capacity of the affected skeletal structures is essential. This process includes strategies to maintain and improve mobility and independence. Individually tailored and adapted physical activity and exercise concepts (programs) within a multidisciplinary and interdisciplinary setting (tumor board) are used to manage the condition and bone load-bearing capacity of the patient. Typical clinical features and complications, such as pathological fractures in patients suffering from metastatic bone disease and additionally hypercalcemia, monoclonal gammopathy with bone marrow aplasia and risk of renal failure in patients with multiple myeloma have to be considered when planning supportive strategies and rehabilitation.

Conclusion

In order to ensure the safety and effectiveness of regular physical activity, exercise, and physical modalities in patients with metastatic bone disease or multiple myeloma, typical contraindications and considerations should be noted.
