Background Prostate cancer patients on androgen deprivation therapy (ADT) experience adverse effects such as lean mass loss, known as sarcopenia, fat gain, and changes in cardiometabolic factors that increase risk of metabolic syndrome (MetS). Resistance training can increase lean mass, reduce body fat, and improve physical function and quality of life, but no exercise interventions in prostate cancer patients on ADT have concomitantly improved body composition and MetS. This pilot trial investigated 12 weeks of resistance training on body composition and MetS changes in prostate cancer patients on ADT. An exploratory aim examined if a combined approach of training and protein supplementation would elicit greater changes in body composition. Methods Prostate cancer patients on ADT were randomized to resistance training and protein supplementation (TRAINPRO), resistance training (TRAIN), protein supplementation (PRO), or control stretching (STRETCH). Exercise groups (EXE = TRAINPRO, TRAIN) performed supervised exercise 3 days per week for 12 weeks, while non-exercise groups (NoEXE = PRO, STRETCH) performed a home-based stretching program. TRAINPRO and PRO received 50 g⋅day − 1 of whey protein. The primary outcome was change in lean mass assessed through dual energy x-ray absorptiometry. Secondary outcomes examined changes in sarcopenia, assessed through appendicular skeletal mass (ASM) index (kg/m 2 ), body fat %, strength, physical function, quality of life, MetS score and the MetS components of waist circumference, blood pressure, glucose, high-density lipoprotein-cholesterol, and triglyceride levels. Results A total of 37 participants were randomized; 32 participated in the intervention (EXE n  = 13; NoEXE n  = 19). At baseline, 43.8% of participants were sarcopenic and 40.6% met the criteria for MetS. Post-intervention, EXE significantly improved lean mass (d = 0.9), sarcopenia prevalence (d = 0.8), body fat % (d = 1.1), strength (d = 0.8–3.0), and prostate cancer-specific quality of life (d = 0.9) compared to NoEXE ( p  < 0.05). No significant differences were observed between groups for physical function or MetS-related variables except waist circumference (d = 0.8). Conclusions A 12-week resistance training intervention effectively improved sarcopenia, body fat %, strength and quality of life in hypogonadal prostate cancer patients, but did not change MetS or physical function. PRO did not offer additional benefit in improving body composition. Trial registration ClinicalTrials.gov: NCT01909440 . Registered 24 July 2013.

ObjectivesWalking is an adaptable, inexpensive and accessible form of physical activity. However, its impact on quality of life (QoL) and symptom severity in people with advanced cancer is unknown. This study aimed to assess the feasibility and acceptability of a randomised controlled trial (RCT) of a community-based walking intervention to enhance QoL in people with recurrent/metastatic cancer.DesignWe used a mixed-methods design comprising a 2-centre RCT and nested qualitative interviews.ParticipantsPatients with advanced breast, prostate, gynaecological or haematological cancers randomised 1:1 between intervention and usual care.InterventionThe intervention comprised Macmillan's ‘Move More’ information, a short motivational interview with a recommendation to walk for at least 30 min on alternate days and attend a volunteer-led group walk weekly.OutcomesWe assessed feasibility and acceptability of the intervention and RCT by evaluating study processes (rates of recruitment, consent, retention, adherence and adverse events), and using end-of-study questionnaires and qualitative interviews. Patient-reported outcome measures (PROMs) assessing QoL, activity, fatigue, mood and self-efficacy were completed at baseline and 6, 12 and 24 weeks.ResultsWe recruited 42 (38%) eligible participants. Recruitment was lower than anticipated (goal n=60), the most commonly reported reason being unable to commit to walking groups (n=19). Randomisation procedures worked well with groups evenly matched for age, sex and activity. By week 24, there was a 45% attrition rate. Most PROMs while acceptable were not sensitive to change and did not capture key benefits.ConclusionsThe intervention was acceptable, well tolerated and the study design was judged acceptable and feasible. Results are encouraging and demonstrate that exercise was popular and conveyed benefit to participants. Consequently, an effectiveness RCT is warranted, with some modifications to the intervention to include greater tailoring and more appropriate PROMs selected.Trial registration numberISRCTN42072606.

Cancer related fatigue (CRF) is a common and debilitating symptom that can influence quality of life (QoL) in cancer patients. The increase in survival times stresses for a better understanding of how CRF affects patients’ QoL. This was a cross-sectional descriptive study with 148 randomly recruited prostate cancer patients aiming to explore CRF and its impact on QoL. Assessments included the Cancer Fatigue Scale, EORTC QLQ-C30, and EORTC QLQ-PR25. Additionally, 15 in-depth structured interviews were performed. Quantitative data were analyzed with simple and multiple regression analysis and independent samples t-test. Qualitative data were analyzed with the use of thematic content analysis. The 66.9% of the patients experienced CRF with higher levels being recorded for the affective subscale. Statistically significant differences were found between the patients reporting CRF and lower levels of QoL (mean = 49.1) and those that did not report fatigue and had higher levels of QoL (mean = 72.1). The interviews emphasized CRF’s profound impact on the patients’ lives that was reflected on the following themes: “dependency on others,” “loss of power over decision making,” and “daily living disruption.” Cancer related fatigue is a significant problem for patients with advanced prostate cancer and one that affects their QoL in various ways.

Background: Due to concerns of fragility fracture, exercise is a perceived contraindication for prostate cancer patients with bone metastases. These patients experience significant functional impairment and muscle atrophy, which may lead to an increased likelihood of skeletal complications (i.e., pathological fracture, bone pain) and/or falls. Safe resistance exercise prescription may counteract this effect. The aim of this feasibility trial was to determine the safety and efficacy of resistance exercise by prostate cancer survivors with bone metastatic disease. Methods: Twenty men with established bone metastases secondary to prostate cancer were randomly assigned to a 12-week resistance exercise program in which exercise prescription was based on the location of bone lesions ( n =10) or usual care ( n =10). Outcomes included safety and tolerance of the exercise program, physical function, physical activity level, body composition, fatigue, quality of life and psychological distress. Outcomes were compared between groups using analysis of covariance adjusted for baseline values. Results: Participants had significant disease load with 65% of participants presenting with two or more regions affected by bone metastases and an average Gleason score of 8.2±0.9. Five participants (exercise=2; usual care=3) did not complete the intervention, three of which were due to advancing disease (exercise=2; usual care=1). No adverse events or skeletal complications occurred during the supervised exercise sessions. The exercise program was well tolerated as evidenced by high attendance (83%) and compliance rates (93%), and the ability of the participants to exercise at an intensity within the target range for cancer survivors (rating of perceived exertion =13.8±1.5). The change in physical function (muscle strength ∼11%; submaximal aerobic exercise capacity ∼5% and ambulation ∼12%), physical activity level (∼24%) and lean mass (∼3%) differed significantly between groups following the intervention, with favorable changes in the exercise group compared with the usual care group. No significant between-group differences were observed for fatigue, quality of life or psychological distress. Conclusions: This initial evidence involving a small sample size suggests that appropriately designed and supervised resistance exercise may be safe and well tolerated by prostate cancer patients with bone metastatic disease and can lead to improvements in physical function, physical activity levels and lean mass. Future trials involving larger sample sizes are required to expand these preliminary findings.

BackgroundPain is an important dimension of quality-of-life in patients with metastatic castrate-sensitive prostate cancer (mCSPC). However, it is unclear if dynamic change in pain over time can predict for overall survival (OS) or progression-free survival (PFS) in these patients.MethodsThis is an exploratory analysis of LATITUDE, a phase III randomized study, in which men with de novo mCSPC were randomized to receive either ADT plus abiraterone versus ADT alone. Information was collected on patient-reported worst pain score (WPS) and pain-interference score (PIS) from the Brief Pain Inventory-Short Form. A Bayesian joint modelling approach was used determine the association of dynamic change in WPS and PIS with OS and PFS.ResultsOverall, 1125 patients with at least 3 measurements on pain scores were eligible. On Cox multivariable regression, increase in baseline WPS was associated with inferior OS (hazard ratio [HR] 1.049 [95% confidence intervals [CI] 1.015–1.085]; time dependent area under curve [tAUC] 0.64) and PFS (HR 1.045 [1.011–1.080]; tAUC: 0.64). Increase in baseline PIS was associated with inferior OS (HR 1.062 [1.020–1.105]; tAUC: 0.63) but not with PFS (HR 1.038 [0.996–1.08]). On independent joint models, an increase in the current value of WPS by 1-unit was associated with inferior OS (HR 1.316 [1.258–1.376]; tAUC 0.74) and PFS (HR 1.319 [1.260–1.382]; tAUC 0.70). Similar association was seen for increase in the current value of PIS with OS (HR 1.319 [1.261–1.381]; tAUC 0.73) and PFS (HR 1.282 [1.224–1.344]; tAUC 0.73).ConclusionsThe above findings highlight the potential dynamic interplay between patient-reported pain with OS and PFS in mCSPC. Compared to baseline pain, such dynamic assessment of pain was found to have superior predictive ability and thus has the potential to tailor subsequent treatment based on response to initial therapy beyond its role as a very important dimension of quality-of-life.

ObjectiveCancer treatment is a particularly stressful period for the patient. The reasons vary and include fear of treatment outcome as well as treatment induced side effects. The patient frequently experiences simultaneously various side effects resulting in a diminishing of the patient’s health-related quality of life (HRQoL). The study provides evidence on the co-occurrence and inter-relations between pain, anxiety, depression and fatigue in patients with breast and prostate cancer.DesignThis paper presents a secondary analysis of the data from a randomised control trial designed to test the effectiveness of guided imagery and progressive muscle relaxation on pain, fatigue, anxiety and depression. Non-parametric bootstrapping analyses were used to test the mediational model of anxiety, fatigue and depression as parallel mediators of the relationship between pain and HRQoL.SettingThe study was undertaken at the home setting.ParticipantsIn total 208 patients were included in the study (assigned equally in two groups), referred at the outpatient clinics of the three participating cancer care centres.ResultsThe three mediators fully mediate the relationship between pain and HRQoL indirect effect (IEoverall=−0.3839, 95% CI: lower limit (LL)=−0.5073 to upper limit (UL)=−0.2825) indicating that patients with increased pain are likely to have higher levels of anxiety, fatigue and depression. Gender significantly moderated the mediational effect of Fatigue Index of Moderated Mediation (IMM=−0.2867 SE=0.1526, LL=−0.6127, UL=−0.0226) but did not moderate mediational effect of anxiety (IMM=−0.0709, SE=0.1414, LL=−0.3459, UL=+0.2089). The results show that the three mediators in a serial causal order fully mediate the relationship between pain and HRQoL (IEoverall=−0.384, 95% CI: LL=−0.51 to UL=−0.284) and the ratio of the overall indirect effect to the total effect is 0.8315 (95% CI: LL=0.5683 to UL=1.1718).ConclusionThis work provides evidence that targeting fatigue, anxiety and depression may have a meaningful effect on pain as a related symptom and potentially have a positive impact on HRQoL of patients with breast and prostate cancerTrial registration number NCT01275872; Post-results.

To identify symptom profiles (e.g., fatigue, sleep disturbance, depression, anxiety, cognitive impairment) among prostate cancer survivors, examine factors associated with the identified symptom profiles, and compare quality-of-life outcomes. 98 prostate cancer survivors who completed primary treatment were enrolled in a randomized parent trial. Established scales were used to measure symptoms and quality of life. Latent profile analysis was employed to classify patient groups based on symptom experiences. Logistic regression assessed factors associated with symptom profiles. The mean age of participants was 69 years (SD = 6.8). A high-symptom group (n = 29) and a low-symptom group (n = 69) were identified. Higher perceived stress (odds ratio [OR] = 1.28; p = 0.006), poorer spiritual well-being (OR = 0.84; p = 0.006), and lower household income (OR = 0.12; p = 0.089) were associated with being classified into the high-symptom group. Patients in the high-symptom group reported worse quality of life across all domains (p < 0.05). Prostate cancer survivors experience varying degrees of symptom severity. Understanding the symptom profiles and associated factors can inform nurses about patients in need of symptom management and targeted interventions.

BackgroundAndrogen deprivation therapy (ADT) and androgen receptor signaling inhibitors (ARSI) are associated with deleterious physical effects, which exercise may mitigate; however, exercise has never been studied in patients initiating treatment with ADT and an ARSI. Our objective was to determine whether supervised exercise prior to and during initial therapy could mitigate adverse effects of ADT plus enzalutamide.MethodsWe conducted a single center trial in patients with recurrent prostate cancer treated with ADT and enzalutamide. We randomized 26 patients to 16 weeks of supervised exercise (aerobic and resistance), starting 4 weeks before initiation of ADT and enzalutamide, or usual care. The primary endpoint was change in peak oxygen uptake (VO2peak) as a measure of cardiorespiratory fitness (CRF). Secondary endpoints were functional capacity, maximal strength, body composition, patient-reported outcomes, safety, and feasibility. Analysis of covariance was used to compare outcomes for groups at Week 17 adjusted for baseline values.ResultsThe usual care group (N = 13) showed declines from baseline to week 17 in both absolute CRF (−0.31 L/min, −10.9%; p < 0.01) and relative CRF (−3.2 mL/kg/min, −8.9%; p = 0.04); worse fatigue (p = 0.01); and worse quality of life (p = 0.01). At week 17, the exercise group (N = 13) demonstrated improved absolute CRF (between-group change +0.20 L/min, p = 0.05), leg strength (+48.6 kg, p < 0.01) and functional capacity (+21.0 m, p = 0.01) at week 17.ConclusionsThis is the first randomized controlled trial demonstrating a clinically significant decline in CRF in patients initiating ADT and enzalutamide. We show the effectiveness of short-term supervised exercise to mitigate declines in absolute CRF, and improve maximal leg strength and functional capacity.ClinicalTrials.gov IdentifierNCT02256111

To test the feasibility of sleep hygiene education and longitudinal wrist actigraph sleep metrics measurement alone versus in combination with telehealth-delivered cognitive behavioral therapy for insomnia (teleCBT-I) for people with prostate cancer (PC) receiving androgen deprivation therapy (ADT). 45 men with PC receiving ADT were recruited from a midwestern comprehensive cancer center. Participants were provided with wrist actigraphs, their individual sleep metrics data, and sleep hygiene education. Half the sample was randomized to a four-week teleCBT-I intervention. Outcomes were collected at baseline, one month, and two months. Exit interviews were conducted to glean participants' feedback about the study. Feasibility was demonstrated. Physical function, sleep efficiency, fatigue, and health-related quality of life improved for participants receiving teleCBT-I. Assessment of sleep disturbance, access to sleep hygiene education, and teleCBT-I may benefit people with PC receiving ADT.

In this companion to the report by Holmberg et al. on survival in a randomized comparison of radical prostatectomy with watchful waiting among men with localized prostate cancer, sexual dysfunction and urinary leakage were more common in the radical-prostatectomy group, but the subjective quality of life in the two groups was similar. In a comparison of prostatectomy with watchful waiting, the quality of life in the two groups was similar. A man with newly diagnosed localized prostate cancer faces a frustrating choice of therapy. 1 He can defer treatment until symptoms appear (watchful waiting), undergo major surgery (radical prostatectomy), or receive radiotherapy (interstitial or external) with the intention of eliminating the tumor. 2 , 3 He may also receive hormonal therapy with antiandrogens or undergo castration. His choice may influence survival as well as the risk of therapy-induced acute or chronic symptoms. 4 Between 1989 and 1999, a group of Swedish urologists enrolled men with localized high-grade or moderate-grade prostate cancer in a randomized trial to compare radical prostatectomy with watchful waiting. 5 We examined . . .
