Exercise is medicine in oncology: Engaging clinicians to help patients move through cancer.

Multiple organizations around the world have issued evidence-based exercise guidance for patients with cancer and cancer survivors. Recently, the American College of Sports Medicine has updated its exercise guidance for cancer prevention as well as for the prevention and treatment of a variety of cancer health-related outcomes (eg, fatigue, anxiety, depression, function, and quality of life). Despite these guidelines, the majority of people living with and beyond cancer are not regularly physically active. Among the reasons for this is a lack of clarity on the part of those who work in oncology clinical settings of their role in assessing, advising, and referring patients to exercise. The authors propose using the American College of Sports Medicine's Exercise Is Medicine initiative to address this practice gap. The simple proposal is for clinicians to assess, advise, and refer patients to either home-based or community-based exercise or for further evaluation and intervention in outpatient rehabilitation. To do this will require care coordination with appropriate professionals as well as change in the behaviors of clinicians, patients, and those who deliver the rehabilitation and exercise programming. Behavior change is one of many challenges to enacting the proposed practice changes. Other implementation challenges include capacity for triage and referral, the need for a program registry, costs and compensation, and workforce development. In conclusion, there is a call to action for key stakeholders to create the infrastructure and cultural adaptations needed so that all people living with and beyond cancer can be as active as is possible for them.

Enhancing circulatory myokines and extracellular vesicle uptake with targeted exercise in patients with prostate cancer (the MYEX trial): a single-group crossover study.

INTRODUCTION: Physical activity is associated with improved disease progression and cancer-specific survival in patients with prostate cancer (PCa). However, the mechanisms underlying these associations remain unclear, while the relative impact of exercise modes is unknown. This study aims to examine the differential impact of exercise mode on tumour-suppressive skeletal muscle-associated systemic molecules as well as their delivery mechanism. This study will compare the effects of the two main exercise modes, aerobic and resistance, on (1) circulatory myokine levels, (2) skeletal muscle-induced extracellular vesicle abundance and cargo contents, and (3) uptake of extracellular vesicles (EVs) in PCa cells in patients with localised or advanced PCa. METHODS: A single-group cross-over design will be used for patients at opposite ends of the disease spectrum. A total of 32 patients (localised PCa, n = 16; metastatic castrate-resistant PCa, n = 16) will be recruited while capitalising on two ongoing studies. Ethics amendment has been approved for two ongoing trials to share data, implement the acute exercise sessions, and collect additional blood samples from patients. The patients will undertake two exercise sessions (aerobic only and resistance only) in random order one week apart. Blood will be collected before, after, and 30 min post-exercise. Circulating/EV-contained myokine levels (irisin, IL-6, IL-15, FGF-21, and SPARC) and plasma skeletal muscle-induced EVs will be measured using ELISA and flow cytometry. PCa cell line growth with or without collected plasma will be examined using PCa cell lines (LNCaP, DU-145, and PC-3), while evaluating cellular uptake of EVs. Ethics amendments have been approved for two capitalising studies to share data, implement acute exercise sessions and collect additional samples from the patients. DISCUSSION: If findings show a differential impact of exercise mode on the establishment of an anti-cancer systemic environment, this will provide fundamental knowledge for developing targeted exercise prescriptions for patients with PCa across different disease stages. 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. TRIAL REGISTRATION: The registration for the two capitalising studies are NCT02730338 and ACTRN12618000225213.

Unleashing anti-tumour immunity: dietary restriction and exercise interventions adjunct to chemotherapy for cancer patients.

Conventional chemotherapies can stimulate the immune system by increasing tumour antigenicity (e.g., neoantigen exposure to immune cells) and altering adjuvanticity in the tumour (e.g., danger associated molecular patterns and cytokines). These molecules promote the recruitment, activation, and maturation of dendritic cells, which in turn, prime and activate cytotoxic T cells against tumour cells. However, several factors can decrease the immunostimulatory efficacy of chemotherapeutic agents. These include reduced tumour cell antigenicity and adjuvanticity and compromised immune function at a local and systemic level. Findings from preclinical studies show that dietary restriction and exercise promote systemic changes that may help to restore immune system function through several mechanisms, including an enhanced infiltration and function of antitumoral immune cells and a decrease in immunosuppressive cells, leading to a reduction in tumour volume. In addition, dietary restriction and exercise training in mice have been shown to enhance the efficacy of chemotherapy. In human studies there is also emerging evidence that dietary restriction and exercise can impact the immune system towards a more antitumoral profile. In this review, we discuss the immunostimulatory effects of dietary restriction (caloric restriction and fasting) and exercise training in preclinical cancer models, and potential synergies with chemotherapy. We then review clinical studies assessing the effects of these interventions on immune-related endpoints and tumour responses. Finally, we propose that combining dietary restriction with exercise could be a promising strategy to increase chemotherapy efficacy.

Dropout from exercise trials among cancer survivors-An individual patient data meta-analysis from the POLARIS study.

INTRODUCTION: The number of randomized controlled trials (RCTs) investigating the effects of exercise among cancer survivors has increased in recent years; however, participants dropping out of the trials are rarely described. The objective of the present study was to assess which combinations of participant and exercise program characteristics were associated with dropout from the exercise arms of RCTs among cancer survivors. METHODS: This study used data collected in the Predicting OptimaL cAncer RehabIlitation and Supportive care (POLARIS) study, an international database of RCTs investigating the effects of exercise among cancer survivors. Thirty-four exercise trials, with a total of 2467 patients without metastatic disease randomized to an exercise arm were included. Harmonized studies included a pre and a posttest, and participants were classified as dropouts when missing all assessments at the post-intervention test. Subgroups were identified with a conditional inference tree. RESULTS: Overall, 9.6% of the participants dropped out. Five subgroups were identified in the conditional inference tree based on four significant associations with dropout. Most dropout was observed for participants with BMI >28.4 kg/m2 , performing supervised resistance or unsupervised mixed exercise (19.8% dropout) or had low-medium education and performed aerobic or supervised mixed exercise (13.5%). The lowest dropout was found for participants with BMI >28.4 kg/m2 and high education performing aerobic or supervised mixed exercise (5.1%), and participants with BMI ≤28.4 kg/m2 exercising during (5.2%) or post (9.5%) treatment. CONCLUSIONS: There are several systematic differences between cancer survivors completing and dropping out from exercise trials, possibly affecting the external validity of exercise effects.

What are the most effective exercise, physical activity and dietary interventions to improve body composition in women diagnosed with or at high-risk of breast cancer? A systematic review and network meta-analysis.

BACKGROUND: Obesity has been recognized as a risk factor in the development and recurrence of breast cancer and is also associated with poor prognostic outcomes. This systematic review and network meta-analysis aimed to identify the most effective exercise, physical activity, and dietary interventions to reduce fat mass, body fat percentage and body weight as well as potentially increase lean mass in women diagnosed with or at high risk of breast cancer. METHODS: A systematic search of databases was performed up to May 2022. Eligible randomized controlled trials examined the effects of exercise, physical activity and/or dietary interventions on fat mass and lean mass in women diagnosed with or at high risk of breast cancer. A random-effects network meta-analysis was conducted to determine the effects of different interventions across outcomes when sufficient studies were available. RESULTS: Eighty-four studies (n = 6428) were included in this review. Caloric restriction and combined exercise + caloric restriction significantly reduced fat mass (range, -3.9 to -3.7 kg) and body weight (range, -5.3 to -4.7 kg), whereas physical activity + caloric restriction significantly reduced body fat percentage (-2.4%; 95% confidence interval [CI], -3.4% to -13%) and body mass index (-2.2 kg × m-2 ; 95% CI, -3.0 to -1.4 kg × m-2 ) in breast cancer patients. Resistance exercise was the most effective intervention to increase lean mass (0.7 kg; 95% CI, 0.5-1.0 kg) in breast cancer patients. CONCLUSION: Multimodal exercise and diet programs were the most effective interventions to reduce fat mass, body fat percentage, and body weight and increase and/or preserve lean mass.

Exercise Mediates Myokine Release and Tumor Suppression in Prostate Cancer Independent of Androgen Signaling.

A prominent toxicity of androgen suppression in patients with prostate cancer (PCa) is loss of skeletal muscle. Exercise may induce tumor suppression through the endocrinal function of skeletal muscle; however, this is currently unknown. In this review, we summarize our work demonstrating the acute and chronic myokine response to exercise and the tumor-suppressive effect of circulatory milieu alteration in PCa patients.

Supervised resistance exercise for women with ovarian cancer who have completed first-line treatment: a pragmatic study.

OBJECTIVES: In ovarian cancer (OC), suboptimal muscle morphology (i.e., low muscle mass and density) is associated with poor clinical outcomes, yet little is known about the effect of interventions aimed at improving these measures. We investigated the effect of resistance exercise after first-line treatment on muscle mass and density, muscle strength and physical function, health-related quality of life (QoL), and pelvic-floor function in advanced-stage OC survivors. METHODS: Fifteen OC survivors participated in supervised resistance exercise twice weekly for 12 weeks (in-clinic or by telehealth). Assessments included muscle mass and density (dual-energy X-ray absorptiometry, peripheral quantitative computed tomography), muscle strength (1-repetition maximum [1RM] chest press, 5RM leg press, handgrip strength), physical function (400-m walk, timed up-and-go [TUG]), QoL (QLQ-C30 questionnaire), and self-reported pelvic floor function (Australian Pelvic Floor Questionnaire). RESULTS: The median age was 64 (range 33-72) years, 10 women underwent neoadjuvant chemotherapy and five underwent adjuvant chemotherapy. All participants completed the intervention (median attendance = 92%; range 79-100%). Post-intervention improvements were observed for whole-body lean mass (1.0 ± 1.4 kg, p = 0.015), appendicular lean mass (0.6 ± 0.9 kg, p = 0.013), muscle density (p = 0.011), upper and lower body strength (p ≤ 0.001), 400-m walk (p = 0.001), TUG (p = 0.005), and social and cognitive QoL domains (p = 0.002 and 0.007), with no change to pelvic floor symptoms (p > 0.05). CONCLUSION: In this study, supervised resistance exercise effectively improved muscle mass and density, muscle strength, and physical functioning without deleterious effects on the pelvic floor. Considering the prognostic value of these outcomes, larger studies are needed to confirm the benefits of resistance exercise in OC supportive care.

Skeletal muscle morphology in patients receiving primary versus interval cytoreductive surgery for advanced high-grade serous ovarian cancer.

OBJECTIVE: Our primary aim was to compare muscle morphology (skeletal muscle mass and density) between patients who underwent primary cytoreductive surgery versus interval cytoreductive surgery for advanced high-grade serous ovarian cancer. Secondarily, we explored the associations of muscle morphology with survival outcomes. METHODS: We retrospectively analysed computed tomography (CT) images for 88 ovarian cancer patients (aged 38-89 years) to calculate skeletal muscle index (cm2/m2) and skeletal muscle density (Hounsfield units (HU)). A skeletal muscle index of <38.5 cm2/m2 and skeletal muscle density of <33.7 HU were classified as low. Analyses included repeated measures analysis of covariance and multivariable Cox proportional hazards regression. RESULTS: At baseline, 44.3% of patients had low skeletal muscle index and 50.6% had low skeletal muscle density, with interval surgery patients having significantly lower mean skeletal muscle density than primary surgery patients (32.2±8.9 vs 37.3±8.6 HU, p=0.014). Although both groups had similar reductions in skeletal muscle index following treatment (p=0.49), primary surgery patients had a greater reduction in skeletal muscle density compared with interval surgery patients (-2.4 HU, 95% CI -4.3 to -0.5, p=0.016). Patients who experienced skeletal muscle density loss >2% during treatment (HR 5.16, 95% CI 1.33 to 20.02) and had low skeletal muscle density post-treatment (HR 58.87, 95% CI 3.70 to 935.68) had significantly worse overall survival. CONCLUSION: Low skeletal muscle index and skeletal muscle density were prevalent at ovarian cancer diagnosis. While both groups experienced muscle mass loss, greater reductions in skeletal muscle density occurred in patients undergoing primary surgery. In addition, skeletal muscle density loss during treatment and low skeletal muscle density post-treatment were associated with poorer overall survival. Supportive care involving resistance exercise targeting muscle hypertrophic drive, and nutrition counseling during and after ovarian cancer treatment may help preserve/enhance muscle mass and density.

Why do men with prostate cancer discontinue active surveillance for definitive treatment? A mixed methods investigation.

OBJECTIVES: To explore the personal and/or medical reasons patients on active surveillance (AS) have, or consider having, further definitive treatment for their prostate cancer. Research suggests up to 50% of patients on AS will discontinue within 5 years, though reasons for discontinuation from the patient's perspective is under-explored. METHODS: Prostate cancer patients who were or had been on AS for at least 6 months were recruited. A questionnaire assessed reasons for receiving/considering definitive treatment and the extent to which reasons were personal or medical. Clinical information was extracted from a state-level population registry. A subset of participants were interviewed to further explore questionnaire responses. RESULTS: One-hundred and-three individuals completed the survey; 33 were also interviewed. Fifty-four survey participants (52%) had discontinued AS for definitive treatment. Common reasons for discontinuation were evidence of disease progression, doctor recommendation, desire to act, and fear of progression. Many participants who considered or had treatment reported weighing medical and personal factors equally in their decision. Interview participants described strongly considering any amount of disease progression and personal factors such as fear of progression, family concerns, and adverse vicarious experiences when deciding whether to pursue treatment. CONCLUSION: Both medical and personal factors are considered when deciding whether to discontinue AS. Identifying predictors of discontinuation is essential for informing supportive care services to improve AS management.

Impact of different unconditional monetary incentives on survey response rates in men with prostate cancer: a 2-arm randomised trial.

BACKGROUND: Men are often viewed as a difficult group to recruit for psychological research, including in psycho-oncology. Whilst research has demonstrated the effectiveness of small monetary incentives for encouraging research participation, little research has examined different large unconditional incentive amounts. Larger unconditional incentives may result in increased participation of men in psychological research. This randomised study within a case-control trial of men diagnosed with early-stage prostate cancer aimed to investigate whether (a) response rates to a 30-min questionnaire completed via mail, online, or phone would vary with different unconditional incentive amounts, and (b) demographics would vary in those who responded within the different incentive groups. METHODS: We conducted this randomised study within a case-control cross-sectional study aiming to identify the social-ecological factors influencing treatment discontinuation in prostate cancer patients. A total of 238 participants from the cross-sectional study were randomised to receive one of two unconditional incentives (n = 121 received AUD$10, n = 117 received AUD$20) with the study materials (consent form and survey). RESULTS: Overall, 113 (47%) responded; n = 61/121 (50.4%) in the AUD$10 group, and n = 52/117 (44.4%) in the AUD$20 group. No evidence of a difference was found in response rates by incentive group (odds ratio 1.27, 95% CI = 0.76-2.12, p = 0.36). Additionally, there were no evident differences in the demographics of the responders vs. non-responders within each incentive group (all p > 0.05). CONCLUSIONS: Unlike previous research, we were unable to show that higher monetary incentives were more effective for increasing response rates. An AUD$20 unconditional incentive may be no more effective than a lesser amount for encouraging prostate cancer survivors to participate in research involving long questionnaires. Future research should consider the cost-benefits of providing large unconditional incentives, as non-responses will result in lost resources perhaps better utilised in other engagement strategies.

Exercise in preventing falls for men with prostate cancer: a modelled cost-utility analysis.

INTRODUCTION: Men who receive androgen deprivation therapy (ADT) for prostate cancer (PCa) are a vulnerable falls population due to the side effects of treatment. The purpose of this paper is to determine the cost-effectiveness of exercise in preventing falls and fractures for this high-risk population in Australia. METHODS: A decision analytic model was constructed to evaluate the cost utility of an exercise intervention compared to usual care from a health system perspective. The intervention comprised two 1-h sessions of supervised exercise per week over 1 year for men with non-metastatic PCa receiving curative radiation therapy and ADT. A Markov model simulated the transition between five health states: (1) at risk of falling; (2) at recurrent risk of falling; (3) fracture (minor or major); (4) non-fracture injury (minor or major); and (5) death. Model inputs including transition probabilities and utility scores were obtained from published meta-analyses, and costs were drawn from Australian data sources (e.g. Medical Benefits Schedule). The model time horizon was 3 years, and costs and effects were discounted at 5% annual rate. Costs and quality-adjusted life years (QALYs) were aggregated and compared between the intervention and control to calculate incremental net monetary benefit (iNMB). Uncertainty in the results was explored using deterministic and probabilistic sensitivity analyses (PSA). RESULTS: At a willingness-to-pay of AU$50,000 per QALY, the exercise intervention dominated, as it was less costly and more effective than usual care. The iNMB was $3010 per patient. The PSA showed a 58% probability the intervention was cost-effective. CONCLUSION: This is the first modelled economic evaluation of exercise for men with PCa. Our results suggest supervised exercise is cost-effective in reducing the risks of falls and fractures in this population.

Social ecological influences on treatment decision-making in men diagnosed with low risk, localised prostate cancer.

OBJECTIVE: Individuals diagnosed with low risk, localised prostate cancer (PCa) face a difficult decision between active surveillance (AS) and definitive treatment. We aimed to explore perceived influences on treatment decision-making from the patient and partner's perspectives. METHODS: Patients (and partners) who met AS criteria and had chosen their treatment were recruited. Semi-structured individual interviews were conducted via telephone to explore experiences of diagnosis, impact on patient lifestyle, experiences with physicians, treatment preferences/choice, treatment information understanding and needs, and overall decision-making process. Interviews were audio recorded, transcribed verbatim, and analysed using Reflexive Thematic Analysis. RESULTS: Twenty-four male patients (18 chose AS) and 12 female partners participated. Five themes relating to social-ecological influences on treatment choice were identified: (1) partner support and direct influence on patient treatment choice, (2) patient and partner vicarious experiences may influence treatment decisions, (3) the influence of the patient's life circumstances, (4) disclosing to wider social networks: friends, family, and co-workers, and (5) the importance of a good relationship and experience with physicians. Additionally, two themes were identified relating to information patients and partners received about the treatment options during their decision-making process. CONCLUSIONS: A range of individual and social influences on treatment decision-making were reported. Physicians providing treatment recommendations should consider and discuss the patient and partner's existing beliefs and treatment preferences and encourage shared decision-making. Further research on treatment decision-making of partnered and non-partnered PCa patients is required. We recommend research considers social ecological factors across the personal, interpersonal, community, and policy levels.

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

BACKGROUND: Despite its therapeutic role during cancer treatment, exercise is not routinely integrated into care and implementation efforts are largely absent from the literature. The aim of this study was to evaluate a strategy to integrate the workflow of a co-located exercise clinic into routine care within a private oncology setting in two clinics in the metropolitan region of Western Australia. METHODS: This prospective evaluation utilised a mixed methods approach to summarise lessons learned during the implementation of an integrated exercise workflow and supporting implementation plan. Data collection was informed by the RE-AIM (Reach, Effectiveness, Adoption, Implementation, Maintenance) framework. Reports detailing utilisation of the exercise service and its referral pathways, as well as patient surveys and meeting minutes documenting the implementation process informed the evaluation. RESULTS: The co-located exercise service achieved integration into routine care within the clinical oncology setting. Patient utilisation was near capacity (reach) and 100% of clinicians referred to the service during the 13-month evaluation period (adoption). Moreover, ongoing adaptations were made to improve the program (implementation) and workflows were integrated into standard operating practices at the clinic (maintenance). The workflow performed as intended for ~70% of exercise participants (effectiveness); however, gaps were identified in utilisation of the workflow by both patients and clinicians. CONCLUSION: Integration of exercise into standard oncology care is possible, but it requires the ongoing commitment of multiple stakeholders across an organisation. The integrated workflow and supporting implementation plan greatly improved utilisation of the co-located exercise service, demonstrating the importance of targeted implementation planning. However, challenges regarding workflow fidelity within and across sites limited its success highlighting the complexities inherent in integrating exercise into clinical oncology care in a real-world setting.

An integrated multicomponent care model for men affected by prostate cancer: A feasibility study of TrueNTH Australia.

OBJECTIVE: To evaluate the feasibility of implementing an integrated multicomponent survivorship care model for men affected by prostate cancer. METHODS: Using a single arm prospective cohort study design, men with prostate cancer were recruited from two regional public hospitals in Australia for a 6-months program that provided information and decision support, exercise and nutrition management, specialised clinical support, and practical support through localised and central care coordination. Carers of the men were also invited to the program. Data were collected from multiple sources to evaluate: (1) recruitment capability and participant characteristics; (2) appropriateness and feasibility of delivering the specific intervention components using an electronic care management tool; and (3) suitability of data collection procedures and proposed outcome measures. RESULTS: Of the 105 eligible men, 51 (consent rate 49%) participated in the program. Of the 31 carers nominated by the men, 13 consented (consent rate 42%). All carers and 50 (98%) men completed the program. Most (92%) men were newly diagnosed with localised prostate cancer. All men attended initial screening and assessment for supportive care needs; a total of 838 episodes of contact/consultation were made by the intervention team either in person (9%) or remotely (91%). The intervention was implemented as proposed with no adverse events. The proposed outcome measures and evaluation procedures were found to be appropriate. CONCLUSIONS: Our results support the feasibility of implementing this integrated multicomponent care model for men affected by prostate cancer.

Patients and carers' perspectives of participating in a pilot tailored exercise program during chemoradiotherapy for high grade glioma: A qualitative study.

OBJECTIVE: To describe glioblastoma patients' and carers' perspectives of participating in a tailored exercise intervention during chemoradiotherapy. METHODS: A pilot study was conducted to evaluate if exercise was a feasible and safe therapy in patients with glioblastoma undergoing chemoradiotherapy. Patients received a supervised exercise intervention involving an individualised prescription of moderate-intensity aerobic and resistance exercise twice weekly, performed at the hospital when they attended for treatment. Semi-structured interviews were conducted with participants and their carers. Recordings were analysed using thematic analysis. RESULTS: 19 patients and 15 carers participated. Benefits and challenges of participating in the exercise intervention were described. Benefits included an individually tailored exercise program, improvements in health, regaining a sense of control, interacting with people, keeping active and benefits for carers. Challenges included managing symptoms associated with diagnosis and treatment, juggling treatment and exercise, and difficulties engaging in the program. CONCLUSION: Patients and carers expressed positive perceptions and experiences of participating in exercise during chemoradiotherapy; however, some challenges were experienced. These results support the quantitative pilot study which demonstrated that supervised exercise is feasible, safe and well tolerated by patients receiving chemoradiotherapy for glioblastoma. Randomised controlled trials now need to be conducted with this population.

Examining the Priorities, Needs and Preferences of Men with Metastatic Prostate Cancer in Designing a Personalised eHealth Exercise Intervention.

BACKGROUND: Few individuals with metastatic prostate cancer have access to prostate cancer-specific exercise support, despite demonstrated benefits. eHealth tools, such as websites, may be viable options for increasing access. To be effective and acceptable, future eHealth websites need to consider end-users' perspectives, capacity and needs. We aim to provide insight into these factors by exploring daily priorities, activities and health literacy of individuals with metastatic prostate cancer and their perspectives towards exercise and exercise-based web-based eHealth interventions. METHODS: Semi-structured interviews explored participant's experiences and understanding of their disease, exercise levels, advice received from health care providers, as well as acceptability of and suggested content for an eHealth tool. A thematic analysis was undertaken. RESULTS: Interviews were conducted with eighteen Australians (55-83 years; M = 71.5, SD = 8.9) living with metastatic prostate cancer. Needing to perform daily responsibilities was a key priority. Participants had limited understanding of the benefits of prostate cancer-specific exercise, and less than half discussed exercise with their health team. Fourteen men felt they could report metastases location, but only four could provide detailed information, which has clinical implications for exercise prescription. A potential web-based intervention was considered acceptable by seventeen men for reasons such as affordability, accessibility and convenience. User-friendly design and practitioner support were important. CONCLUSIONS: Results identified key aspects useful for person-centred design of exercise programs. Participants were positive towards the proposed web-based tool and expressed the need for individualised, user-friendly and reliable information with support from a professional embedded. Lastly, not all participants could accurately report metastasis locations.

We have the program, what now? Development of an implementation plan to bridge the research-practice gap prevalent in exercise oncology.

BACKGROUND: Exercise has emerged as a promising therapy for people with cancer. Novel programs have been developed to translate research into practice; however, implementation barriers have limited their success in part because successful translation of exercise oncology research into practice requires context-specific implementation plans. The aim of this study was to employ the implementation mapping protocol to develop an implementation plan to support programming of a co-located exercise clinic and cancer treatment center. METHODS: The Implementation Mapping protocol, which consists of five specific iterative tasks, was used. A stakeholder advisory group advised throughout the process. RESULTS: A comprehensive needs assessment was used to identify the organization's general manager as the program adopter; oncologists, center leaders, and various administrative staff as program implementers; and the operations manager as the program maintainer. Twenty performance objectives were identified. The theoretical domains framework was used to identify likely determinants of change, which informed the selection of eight individual implementation strategies across the individual and organizational levels. Finally, an evaluation plan was developed which will be used to measure the success of the implementation plan in the project's next phase. CONCLUSION: The Implementation Mapping protocol provided a roadmap to guide development of a comprehensive implementation plan that considered all ecological domains, was informed by theory, and demonstrated an extensive understanding of the implementation context. Strong research-practitioner partnerships and effective stakeholder engagement were critical to development of the plan.

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.

Incidence of the adverse effects of androgen deprivation therapy for prostate cancer: a systematic literature review.

PURPOSE: Androgen deprivation therapy (ADT) has broad application in the treatment of prostate cancer (PC) and is associated with numerous, debilitating adverse effects. Increasing use of ADT for PC, longer timeframe for treatment (increased uptake of PSA testing and earlier diagnosis), as well as improved survival and an ageing population, means patients can live for a considerable period of time on or after ADT, experiencing these adverse effects. A number of systematic reviews of adverse effects of ADT for PC exist; however, no single systematic review has previously examined the evidence for all adverse effects, including newer forms of ADT. METHODS: A systematic review of existing systematic reviews of ADT for PC was conducted (2010-February 2019), as per Cochrane guidelines, to identify the highest level of risk/incidence evidence available, supplemented by evidence drawn from individual studies where no systematic review existed. RESULTS: Incidence data was generated for 19 adverse effect subgroups, classified according to the common terminology criteria for adverse events (CTCAE). CONCLUSION: Incidence of adverse effects provides valuable information for future burden of disease studies. This information can better guide clinical management to reduce symptoms for patients and assist patients to make more informed decisions about their treatment, potentially improving disease outcomes. It also highlights the importance of supportive care for PC patients receiving ADT and their carers. For analysts conducting economic evaluations, the inclusion of adverse effects in PC decision analytic models can provide more comprehensive and accurate information for decision makers.

If you build it, will they come? Evaluation of a co-located exercise clinic and cancer treatment centre using the RE-AIM framework.

OBJECTIVE: Employ the Reach, Effectiveness, Adoption, Implementation, Maintenance framework to evaluate the effectiveness of a co-located exercise clinic model in increasing access to exercise for people undergoing cancer treatment in a private clinic in Western Australia. METHODS: This retrospective evaluation utilised a mixed-method approach to gather feedback from key stakeholder groups involved with the exercise clinic. Questionnaires and workout summary sheets were gathered from 237 exercise clinic participants over the 50-month evaluation period. These were supplemented by survey results from 119 patients who received cancer treatment at the facility, and semi-structured interviews from seven radiation oncologists, eight nurses, and three accredited exercise physiologists involved with the exercise clinic. RESULTS: The co-located clinic demonstrated positive outcomes related to effectiveness and adoption. Participant feedback indicated satisfaction with the exercise programming (effectiveness), and clinicians were receptive to referring patients to the clinic (adoption). However, no clear implementation or maintenance plan was employed and overall reach (12%) remained suboptimal throughout the evaluation period. CONCLUSION: Co-locating an exercise clinic into a treatment facility does not in itself overcome the logistical challenges of providing integrated exercise services to people during cancer treatment. To enhance its utilisation, an implementation plan needs to accompany the intervention.
