Project description:INTRODUCTION:Level 1 evidence supports the use of supervised exercise to mitigate the adverse effects of androgen deprivation therapy (ADT) in men with prostate cancer. The data, however, have been generated in controlled research settings and might not be transferable to daily clinical practice. This article describes the design of an ongoing prospective observational study to evaluate the potential benefits of exercise in daily clinical practice. METHODS AND ANALYSIS:Men diagnosed with prostate cancer starting or already receiving ADT at our facility are invited to participate in a 12-week exercise programme implemented as the standard of care. Exclusion criteria are opioid-demanding treatment for skeletal pain, an Eastern Cooperative Oncology Group (ECOG) performance status above 2 or the inability to perform floor and machine exercises independently. The intervention consists of an initial educational session of 1½?hours followed by 12?weeks of group-based supervised training two times a week. The focus of the exercise is progressive resistance training in combination with aerobic training. Participants are measured at baseline, after 12?weeks and after 24?weeks as part of the programme. Primary endpoints of this study are changes in physical fitness evaluated by the 30?s Chair-Stand Test and Graded Cycling Test with Talk Test. Secondary endpoints include changes in quality of life, body composition and safety of exercise. Inclusion started in August 2014, with 169 participants being included by December 2015. ETHICS AND DISSEMINATION:The study has been reviewed by the Scientific Ethical Committee of the Capital Region of Denmark (reference number H-3-2013-FSP39). The results of the study will be published in peer-reviewed international journals and will be presented at national and international conferences and symposiums. TRIAL REGISTRATION NUMBER:NCT02631681; Pre-results.

Project description:BackgroundAndrogen deprivation therapy (ADT) has adverse effects on body composition, including muscle wasting and body fat accumulation, which may be attenuated by nutrition therapy. This systematic review summarises available evidence on the effects of dietary interventions on lean mass, fat mass and body mass index (BMI) in men treated with ADT for prostate cancer.MethodsMEDLINE, Embase, Web of Science and ClinicalTrials.org were searched from inception through December 2020. We included all controlled trials evaluating effects of supplementation or dietary interventions on body composition in men with prostate cancer receiving continuous ADT. Methodological quality of the studies was assessed using the Cochrane Collaboration's risk of bias tool. Meta-analysis was performed using a random effects model to calculate standardised mean differences between intervention and comparator groups. (PROSPERO; CRD42020185777).ResultsEleven studies (n = 536 participants) were included. Seven studies investigated the effects of dietary advice interventions, e.g. individual or group counselling, and four studies included a nutritional supplement. Eight studies combined the dietary intervention with exercise. Nine studies reported sufficient data for inclusion in the meta-analysis. Dietary advice and supplementation interventions combined were not associated with significant changes in lean mass (0.05 kg; 95% CI: -0.17, 0.26; p = 0.674; n = 355), fat mass (-0.22 kg; 95% CI: -0.45, 0.01; p = 0.064; n = 336) or BMI (-0.16 kg*m-2; 95% CI: -0.37, 0.04; p = 0.121; n = 399). Dietary advice interventions alone were associated with a significant fat mass reduction (-0.29 kg; 95% CI: -0.54, -0.03; p = 0.028; n = 266).ConclusionsMost studies were dietary advice interventions targeting caloric restriction, which showed the potential to reduce fat mass but did not increase lean mass in men treated with ADT. Future interventions should investigate whether a combination of dietary advice and protein supplementation with concomitant resistance exercise could counteract ADT-induced muscle wasting.

Project description:Interventions: Men with prostate cancer receiving androgen deprivation therapy will attend three clinic-based supervised exercise sessions each week, for 12 weeks (3 months), consisting of moderate-to-high intensity resistance and aerobic exercise (interval and continuous). Each session will take approximately 60 minutes, including warm-up and cool-down, and will be supervised by accredited exercise physiologists (AEP; Exercise and Sport Science Australia, Brisbane, Australia), face-to-face (in groups of up to 8 people per session). The exercise program is designed to provide optimal stimulus to the cardiorespiratory and neuromuscular systems while maximising safety, compliance and retention, thus will be tailored, progressive, periodised and autoregulated in collaboration with the patient (i.e. adjusted based on the patient’s presentation at each session).
Resistance exercise will be prescribed using repetition maximums (RM), where patients will be required to perform 6-8 different resistance exercises using major muscle groups, at 6-12 RM (the maximal weight that can be lifted 6 to 12 times each set, equivalent to ~60-85% of 1RM) for 3-4 sets per exercise to achieve moderate-to-high intensity and volume. Aerobic exercise will include 20 to 30 minutes of moderate-to-vigorous intensity activity (equating to ~60-85% of estimated maximum heart rate; or a rating of perceived exertion (RPE) between 6-9 using the BORG-10 scale) involving a variety of modes including walking, jogging, cycling or rowing, using treadmills and/or stationary ergometers respectively. Aerobic intensity will be monitored using heart rate monitors (Polar M400, H10 Sensor, Polar Electro, NSW, Australia) and an RPE chart for assessment. Patients will also be encouraged to perform additional aerobic exercise

Project description:BackgroundExercise and dietary (EX+D) interventions could represent an optimal treatment for attenuating or reversing adverse effects of androgen deprivation therapy (ADT) in prostate cancer (PCa) patients. The Individualized Diet and Exercise Adherence-Pilot (IDEA-P) trial compared the effects of an EX+D intervention relative to standard-of-care (SC) treatment among PCa patients undergoing ADT. The present study evaluated the effects of the EX+D intervention on body composition (BC) obtained via dual-energy X-ray absorptiometry (DXA) in a subsample of IDEA-P patients. A secondary objective was to explore the association of adiposity and lean mass with mobility performance and strength.MethodsComplete DXA data were acquired from a subsample of 22 PCa patients (EX+D: n = 13; SC: n = 9) at baseline and 3 month follow-up. Intention-to-treat analysis included data from 30 participants (M age = 66.28; SD = 7.79) with baseline DXA assessments.ResultsIntention-to-treat analysis revealed EX+D resulted in significant improvements in fat mass (P = 0.022), per cent fat mass (P = 0.028), trunk fat mass (P = 0.017), fat mass/lean mass (P = 0.040), and per cent lean mass (P = 0.026) vs. SC. EX+D also resulted in more favourable changes in appendicular lean mass/body mass (d = 0.59). Select BC outcomes were also significantly correlated with mobility performance and strength (P < 0.05) at 3 month follow-up.ConclusionsFindings suggest the EX+D intervention resulted in superior preservation of lean tissue and improvement in adiposity relative to SC treatment. Results underscore the utility of implementing EX+D interventions for preserving muscle mass and reducing adiposity in PCa patients undergoing ADT.

Project description:ObjectivesAndrogen deprivation therapy (ADT) has seen increasing use as a prostate cancer treatment in recent years and has proven medically effective in numerous contexts. The treatment, however, is associated with a host of side effects including depression. Managing the psychological wellbeing of prostate cancer patients is important for maximizing their survival outcomes. Thus, this study aimed to evaluate depressive symptomatology in patients with androgen deprivation therapy (ADT) compared with that in patients who underwent prostatectomy and to explore the factors that affect depressive symptoms, which might occur during ADT.MethodsOne hundred and seven patients undergoing ADT (ADT group) and prostatectomy (Operation group) were enrolled. Adjustments were made for differences in characteristics between groups using a propensity score model with stabilized weights before treatment. Depressive symptoms between groups were compared using the Beck Depression Inventory (BDI) before treatment and six months after treatment initiation. To identify factors affecting depressive symptoms during ADT, multivariate regression analysis was performed on the mean change in BDI score, age, body mass index, testosterone level, prostate-specific antigen level, the international index of erectile function (IIEF), and the Gleason score.ResultsThe BDI score significantly increased in the ADT group compared to the operation group six months after treatment initiation (p < 0.001). Multivariate regression analysis revealed that before ADT, the BDI score was higher by 0.446 according to the IIEF. During ADT, the BDI score increased by 1.579 according to changes in BMI (p = 0.021) and decreased by 0.01 according to changes in testosterone levels (p = 0.034).ConclusionDepressive symptoms can be exacerbated in prostate cancer patients undergoing ADT. Efforts are needed to diagnose and treat depression appropriately, especially if depressive symptoms change in ADT patients with a high IIEF score before ADT, or reduced testosterone levels or increased BMI during ADT.

Project description:Androgen deprivation therapy (ADT) improves prostate cancer outcomes in specific clinical settings, but is associated with adverse effects, including cardiac complications and possibly thromboembolic complications. The objective of this study was to estimate the impact of ADT on thromboembolic events (TEs) in a population-based cohort.In the linked Surveillance, Epidemiology and End Results-Medicare database, we identified men older than 65 who were diagnosed with nonmetastatic prostate cancer between 1999 and 2005. Medical or surgical ADT was identified by Medicare claims for gonadotropin-releasing hormone agonists or bilateral orchiectomy at any time following diagnosis. TEs included deep venous thrombosis, pulmonary embolism, and arterial embolism. The impact of ADT on the risk of any TE and on total number of events was estimated, controlling for patient and tumor characteristics.Of 154,611 patients with prostate cancer, 58,466 (38%) received ADT. During a median follow-up of 52 months, 15,950 men had at least 1 TE, including 8829 (55%) who had ADT and 7121 (45%) with no ADT. ADT was associated with increased risk of a TE (adjusted hazard ratio = 1.56; 95% confidence interval, 1.50-1.61; P < .0001), and duration of ADT was associated with the total number of events (P < .0001).In this population-based cohort, ADT was associated with increased risk of a TE, and longer durations of ADT were associated with more TEs. Men with intermediate- and low-risk prostate cancer should be assessed for TE risk factors before starting ADT and counseled regarding the risks and benefits of this therapy.

Project description:Androgen-deprivation therapy is well-established for treating prostate cancer but is associated with bone loss and an increased risk of fracture. We investigated the effects of denosumab, a fully human monoclonal antibody against receptor activator of nuclear factor-kappaB ligand, on bone mineral density and fractures in men receiving androgen-deprivation therapy for nonmetastatic prostate cancer.In this double-blind, multicenter study, we randomly assigned patients to receive denosumab at a dose of 60 mg subcutaneously every 6 months or placebo (734 patients in each group). The primary end point was percent change in bone mineral density at the lumbar spine at 24 months. Key secondary end points included percent change in bone mineral densities at the femoral neck and total hip at 24 months and at all three sites at 36 months, as well as incidence of new vertebral fractures.At 24 months, bone mineral density of the lumbar spine had increased by 5.6% in the denosumab group as compared with a loss of 1.0% in the placebo group (P<0.001); significant differences between the two groups were seen at as early as 1 month and sustained through 36 months. Denosumab therapy was also associated with significant increases in bone mineral density at the total hip, femoral neck, and distal third of the radius at all time points. Patients who received denosumab had a decreased incidence of new vertebral fractures at 36 months (1.5%, vs. 3.9% with placebo) (relative risk, 0.38; 95% confidence interval, 0.19 to 0.78; P=0.006). Rates of adverse events were similar between the two groups.Denosumab was associated with increased bone mineral density at all sites and a reduction in the incidence of new vertebral fractures among men receiving androgen-deprivation therapy for nonmetastatic prostate cancer.

Project description:PurposeAndrogen-deprivation therapy (ADT) for prostate cancer is associated with bone loss and osteoporotic fractures. Our objective was to examine changes in bone density and turnover with sustained, discontinued, or delayed oral bisphosphonate therapy in men receiving ADT.Patients and methodsA total of 112 men with nonmetastatic prostate cancer receiving ADT were randomly assigned to alendronate 70 mg once weekly or placebo in a double-blind, partial-crossover trial with a second random assignment at year 2 for those who initially received active therapy. Outcomes included bone mineral density and bone turnover markers.ResultsMen initially randomly assigned to alendronate and randomly reassigned at year 2 to continue had additional bone density gains at the spine (mean, 2.3% +/- 0.7) and hip (mean, 1.3% +/- 0.5%; both P < .01); those randomly assigned to placebo in year 2 maintained density at the spine and hip but lost (mean, -1.9% +/- 0.6%; P < .01) at the forearm. Patients randomly assigned to begin alendronate in year 2 experienced improvements in bone mass at the spine and hip, but experienced less of an increase compared with those who initiated alendronate at baseline. Men receiving alendronate for 2 years experienced a mean 6.7% (+/- 1.2%) increase at the spine and a 3.2% (+/- 1.5%) at the hip (both P < .05). Bone turnover remained suppressed.ConclusionAmong men with nonmetastatic prostate cancer receiving ADT, once-weekly alendronate improves bone density and decreases turnover. A second year of alendronate provides additional skeletal benefit, whereas discontinuation results in bone loss and increased bone turnover. Delay in bisphosphonate therapy appears detrimental to bone health.

Project description:PurposeAndrogen 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.MethodsWe 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.ResultsNine 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.ConclusionEvidence 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.Trial registrationThe study protocol was registered with International Prospective Register of Systematic Reviews (PROSPERO, number CRD 42020158444 ) on 04/28/2020.

Project description:Androgen deprivation therapy (ADT) is a cornerstone in the treatment of advanced prostate cancer. Adverse musculoskeletal and cardiovascular effects of ADT are widely reported and investigations into the potential of exercise to ameliorate the effects of treatment are warranted. The 'Football Club (FC) Prostate' study is a randomized trial comparing the effects of soccer training with standard treatment approaches on body composition, cardiovascular function, physical function parameters, glucose tolerance, bone health, and patient-reported outcomes in men undergoing ADT for prostate cancer.Using a single-center randomized controlled design, 80 men with histologically confirmed locally advanced or disseminated prostate cancer undergoing ADT for 6 months or more at The Copenhagen University Hospital will be enrolled on this trial. After baseline assessments eligible participants will be randomly assigned to a soccer training group or a control group receiving usual care. The soccer intervention will consist of 12 weeks of training 2-3 times/week for 45-60 min after which the assessment protocol will be repeated. Soccer training will then continue bi-weekly for an additional 20 weeks at the end of which all measures will be repeated to allow for additional analyses of long-term effects. The primary endpoint is changes in lean body mass from baseline to 12 weeks assessed by dual X-ray absorptiometry scan. Secondary endpoints include changes of cardiovascular, metabolic, and physical function parameters, as well as markers of bone metabolism and patient-reported outcomes.The FC Prostate trial will assess the safety and efficacy of a novel soccer-training approach to cancer rehabilitation on a number of clinically important health outcomes in men with advanced prostate cancer during ADT. The results may pave the way for innovative, community-based interventions in the approach to treating prostate cancer.ClinicalTrials.gov: NCT01711892.
