Exercise as a supportive care strategy in men with prostate cancer receiving androgen deprivation therapy at a regional cancer centre: a survey of patients and clinicians.

ABSTRACT:

Purpose

To understand how frequently exercise is discussed and/or prescribed as a supportive care measure and the barriers and facilitators to exercise uptake for men with prostate cancer receiving androgen deprivation therapy (ADT) at a regional cancer centre.

Methods

An observational, cross-sectional study was conducted at a regional cancer centre in three stages: (1) Retrospective chart review of men with prostate cancer undergoing ADT to identify the frequency of discussion and/or prescription of supportive care measures; (2) prospective patient survey exploring barriers and facilitators to exercise; and (3) prospective clinician survey exploring barriers, facilitators and awareness of exercise guidelines in men with prostate cancer.

Results

Files of 100 men receiving ADT (mean age 73 years; mean ADT duration =12 months) in the medical oncology (n = 50) and radiation oncology (n = 50) clinics were reviewed. Exercise was discussed with 16% of patients and prescribed directly to 5%. Patient survey (n = 49). 44.2% of patients reported participating in exercise at a high level. Common barriers to exercise participation included fatigue (51.0%), cancer/treatment-related weakness (46.9%) and joint stiffness (44.9%). 36.7% of patients reported interest in a supervised exercise program. Clinician survey (n = 22). 36.4% identified one or more exercise guidelines, and 40.9% correctly identified national exercise guidelines. Clinicians reported low knowledge of referral pathways to a supervised exercise program (27.3%). Clinicians believe physiotherapists (95.5%) are most suited to exercise prescription and 72.7% stated that exercise counselling should be part of supportive care. Limited time (63.6%) and patient safety (59.1%) were the two most common barriers to discussing exercise with patients. Clinicians reported that only 21.9% of their patients asked about exercise. The most endorsed facilitators to increase exercise uptake were patient handouts (90.9%) and integration of exercise specialists into the clinical team (86.4%).

Conclusion

Despite a third of patient respondents indicating an interest in a supervised exercise program, only 16% of patients with prostate cancer undergoing ADT at a regional cancer centre engaged in a discussion about exercise with their treating clinicians. Physical limitations and fatigue were the greatest barriers for patients. Clinicians indicated a need for more clinician education and better integration of exercise specialists into clinical care. A tailored, integrated approach is needed to improve the uptake of exercise in men with prostate cancer.

Project description:BackgroundAndrogen deprivation therapy (ADT) is the mainstay therapy for men with prostate cancer. However, there are musculoskeletal side effects from ADT that increase the risk for osteoporosis and fracture, and can compromise the quality of life of these individuals. The objectives of this study are to determine the efficacy of a home-based walking exercise program in promoting bone health, physical function and quality of life in men with prostate cancer receiving ADT.Methods/designA 12-month prospective, single-blinded, randomized controlled trial will be conducted to compare the Exercise Group with the Control Group. Sixty men with prostate cancer who will be starting ADT will be recruited and randomly assigned to one of the two groups: the Exercise Group will receive instructions in setting up an individualized 12-month home-based walking exercise program, while the Control Group will receive standard medical advice from the attending physician. A number of outcome measures will be used to assess bone health, physical function, and health-related quality of life. At baseline and 12 months, bone health will be assessed using dual-energy X-ray absorptiometry. At baseline and every 3 months up to 12 months, physical function will be evaluated using the Functional Assessment of Chronic Illness Therapy - Fatigue Scale, Activities-specific Balance Confidence Scale, Short Physical Performance Battery, and Six-Minute Walk Test; and health-related quality of life will be assessed using the Functional Assessment of Cancer Therapy Prostate Module and the Medical Outcomes Study 12-item Short Form Health Survey Version 2. A mixed multiple analysis of variance will be used to analyze the data.DiscussionMusculoskeletal health management remains a challenge in men with prostate cancer receiving ADT. This study addresses this issue by designing a simple and accessible home-based walking exercise program that will potentially have significant impact on reducing the risk of fracture, promoting physical function, and ultimately improving the health-related quality of life in men with prostate cancer receiving ADT.Trial registrationClinicalTrials.gov: NCT00834392.

Project description:IntroductionA potential link exists between prostate cancer (PCa) disease and treatment and increased inflammatory levels from gut dysbiosis. This study aims to examine if exercise favourably alters gut microbiota in men receiving androgen deprivation therapy (ADT) for PCa. Specifically, this study will explore whether: (1) exercise improves the composition of gut microbiota and increases the abundance of bacteria associated with health promotion and (2) whether gut health correlates with favourable inflammatory status, bowel function, continence and nausea among patients participating in the exercise intervention.Methods and analysisA single-blinded, two-armed, randomised controlled trial will explore the influence of a 3-month exercise programme (3 days/week) for men with high-risk localised PCa receiving ADT. Sixty patients will be randomly assigned to either exercise intervention or usual care. The primary endpoint (gut health and function assessed via feacal samples) and secondary endpoints (self-reported quality of life via standardised questionnaires, blood biomarkers, body composition and physical fitness) will be measured at baseline and following the intervention. A variety of statistical methods will be used to understand the covariance between microbial diversity and metabolomics profile across time and intervention. An intention-to-treat approach will be utilised for the analyses with multiple imputations followed by a secondary sensitivity analysis to ensure data robustness using a complete cases approach.Ethics and disseminationEthics approval was obtained from the Human Research Ethics Committee of Edith Cowan University (ID: 19827 NEWTON). Findings will be reported in peer-reviewed publications and scientific conferences in addition to working with national support groups to translate findings for the broader community. If exercise is shown to result in favourable changes in gut microbial diversity, composition and metabolic profile, and reduce gastrointestinal complications in PCa patients receiving ADT, this study will form the basis of a future phase III trial.Trial registration numberANZCTR12618000280202.

Project description:BACKGROUND:National guidelines (NICE-CG175) recommended 12 weeks of supervised exercise training for men treated with androgen deprivation therapy (ADT) for prostate cancer to counter debilitating adverse effects of castration. As with other chronic conditions where exercise is indicated, it is uncertain if these services are being delivered in the health services. The aim of this multi-centre investigation was to examine what exercise referral is currently available for men on ADT as provided by the NHS and if a supervised, individually-tailored exercise training package (as per the national NICE guidelines CG175) is embedded within prostate cancer care. METHODS:A multi-centre investigation of current National Health Service (NHS) care involving a web-based survey of NHS prostate cancer care, five focus groups involving 26 men on ADT and 37 semi-structured interviews with healthcare professionals (HCPs) involved in the management of prostate cancer. Descriptive statistics and thematic analysis evaluated quantitative and qualitative data, respectively. Qualitative methods followed COREQ standards. RESULTS:HCPs and men on ADT asserted that medical castration has a serious and debilitating impact on many features of men's quality of life. There is support for exercise training programmes as part of cancer care and patients would support their initiation soon after diagnosis. Involving the Multidisciplinary Team (MDT) is proposed as key to this. Critically, traditional values in oncology would need to be overcome for widespread acceptance. Specialist further training for HCPs around behaviour change support could encourage this. Given that these schemes are seen as a fundamental part of cancer care, it is felt the NHS should commission and support provision. 79 representatives of 154 NHS trusts (51%) provided survey data on current delivery: only 17% could provide supervised exercise as per CG175. CONCLUSIONS:Evidence-based national exercise guidelines are not being delivered to men on ADT as intended. Traditional values in oncology and the need for NHS financial support are seen as major barriers to provision of current best practice guidelines. Despite this both HCPs and men on ADT are in favour of such programmes being a fundamental part of their cancer care.
