RESUMO
Guidelines promote high quality cancer care. Rehabilitation recommendations in oncology guidelines have not been characterized and may provide insight to improve integration of rehabilitation into oncology care. This report was developed as a part of the World Health Organization (WHO) Rehabilitation 2030 initiative to identify rehabilitation-specific recommendations in guidelines for oncology care. A systematic review of guidelines was conducted. Only guidelines published in English, for adults with cancer, providing recommendations for rehabilitation referral and assessment or interventions between 2009 and 2019 were included. 13840 articles were identified. After duplicates and applied filters, 4897 articles were screened. 69 guidelines were identified with rehabilitation-specific recommendations. Thirty-seven of the 69 guidelines endorsed referral to rehabilitation services but provided no specific recommendations regarding assessment or interventions. Thirty-two of the 69 guidelines met the full inclusion criteria and were assessed using the AGREE II tool. Twenty-one of these guidelines achieved an AGREE II quality score of ≥ 45 and were fully extracted. Guidelines exclusive to pharmacologic interventions and complementary and alternative interventions were excluded. Findings identify guidelines that recommend rehabilitation services across many cancer types and for various consequences of cancer treatment signifying that rehabilitation is a recognized component of oncology care. However, these findings are at odds with clinical reports of low rehabilitation utilization rates suggesting that guideline recommendations may be overlooked. Considering that functional morbidity negatively affects a majority of cancer survivors, improving guideline concordant rehabilitative care could have substantial impact on function and quality of life among cancer survivors.

BACKGROUND: Limited data exist regarding the role of multimodal prehabilitation during neoadjuvant chemotherapy (NACT) for breast cancer. Determining large trial feasibility and identifying signals of prehabilitation benefit are needed. PATIENTS AND METHODS: We conducted a randomized controlled feasibility trial of multimodal prehabilitation versus usual care during NACT among women diagnosed with non-metastatic breast cancer. Intervention participants received an individualized exercise program, dietetic support, and stress management counseling during NACT. The trial assessed feasibility via rates of recruitment, attrition, adherence, and study-related adverse events. Physical fitness (Six Minute Walk Test, grip strength, anthropometrics) and patient-reported outcomes were assessed at baseline, after NACT completion, and 6 months after surgery as exploratory outcomes, and analyzed using linear mixed effects models. Qualitative data were collected from a subsample to understand feasibility and acceptability of prehabilitation. RESULTS: A total of 72 participants were enrolled from the 123 eligible patients (recruitment rate of 53%). There was a 13% attrition rate and no intervention-related adverse events. Participants in the prehabilitation group had better 6-min walk distance at the post-chemotherapy timepoint [between group difference of 49.43 m, 95% confidence interval (CI) - 118.1, 19.2] and at the post-surgery timepoint (27.3, 95% CI -96.8, 42.2) compared with the control group. Prehabilitation participants reported better quality of life, less fatigue, and improved physical activity levels compared with usual care participants. Interviews revealed that the intervention had a positive impact on the treatment experience. CONCLUSIONS: This study demonstrated feasibility and improvement in physical and psychosocial outcomes. Larger trials assessing intervention efficacy to confirm indications of prehabilitation benefit are warranted.

Prehabilitation aims to optimise patients' physical and psychological status before treatment. The types of outcomes measured to assess the impact of prehabilitation interventions vary across clinical research and service evaluation, limiting the ability to compare between studies and services and to pool data. An international workshop involving academic and clinical experts in cancer prehabilitation was convened in May 2022 at Sheffield Hallam University's Advanced Wellbeing Research Centre, England. The workshop substantiated calls for a core outcome set to advance knowledge and understanding of best practice in cancer prehabilitation and to develop national and international databases to assess outcomes at a population level.

Mounting evidence suggests that recovery begins before the surgical incision. The presurgery phase of recovery, namely the preparation for optimal surgical recovery, can be reinforced with prehabilitation. Prehabilitation is the approach of enhancing the functional capacity of the individual to enable them to withstand a stressful event. With this narrative review, we apply the Wilson and Cleary conceptual model of patient outcomes to specify the complex and integrative relationship of health factors that limit functional capacity before surgery. To have the greatest impact on patient outcomes, prehabilitation programs require individualised and coordinated care from medical, nutritional, psychosocial and exercise services.

BACKGROUND: The majority of breast cancer survivors do not engage in sufficient levels of exercise. Community-based exercise programs (CBEP) may mitigate low rates of exercise participation; however, few programs exist. Previous research exploring the determinants of CBEP implementation for cancer survivors is limited in that it has predominantly focused on cancer survivor perspectives or it has failed to rely on a theoretical framework to explore determinants to implementation across various implementation domains. An organizational exploration of the determinants of CBEP implementation for breast cancer survivors is warranted to guide future program implementation. PURPOSE: The purpose of this study was to apply the Consolidated Framework for Implementation Research (CFIR) to explore the determinants of CBEP implementation for breast cancer survivors from a program provider perspective. METHODS: Data collection and analysis were guided by the CFIR. Program providers completed an online questionnaire and an interview. Transcripts were analyzed using inductive content analysis. Resulting codes were deductively mapped onto the CFIR. RESULTS: Seven barriers and seven facilitators were identified, with three key influencers (e.g., program awareness, financial support, and knowledge regarding the benefits of exercise for breast cancer survivors) cited as both barriers and facilitators to program implementation. Barriers primarily operated within the outer setting (e.g., needs and resources) domain of the CFIR, whereas facilitators and key influencers operated across multiple CFIR domains (e.g., culture and planning). CONCLUSIONS: Study findings provide insight into the current challenges to CBEP implementation experienced by program providers and highlight potential avenues for future exercise program development and implementation.

Physical activity (PA) can help manage cancer treatment-related side effects and improve well-being following treatment; however, resuming PA after a period of inactivity due to cancer can be challenging. The purpose of this study was to explore adolescents and young adults (AYAs) experiences transitioning back into PA after a period of inactivity due to cancer treatment. Twelve previously active AYAs (Mage = 30 ± 5.8 years) were purposefully sampled and engaged in a semi-structured interview. The following four themes were generated through a reflexive thematic analysis: PA is described as important and valuable; navigating one's appearance and fitness changes after cancer treatment within the PA context; supportive care is essential to successful PA transitions; and juxtaposed environments: fitness facilities, cities, and green spaces. Developing strategies aimed at gradually transitioning into PA should be a priority to improve AYAs' well-being through survivorship.

OBJECTIVE: Cancer and treatment can produce temporary or permanent body changes, which may affect the body image (BI) of adolescents and young adults diagnosed with cancer (AYAs). This evidence has not been comprehensively summarized. A scoping review was conducted to explore the available evidence on BI among AYAs and identify the definitions, theories, models, frameworks, measures, and methods used to assess BI. METHODS: Databases MEDLINE, EMBASE, PsycINFO (via Ovid) and CINAHL and Gender Studies (via EBSCO) were searched to identify published studies from 1 January 2000 to 25 November 2019. Inclusion criteria were: qualitative, quantitative, or mixed methodology; at least one BI-related measure or theme; published in English; and majority of the sample between 13 and 39 years at diagnosis and a mean age at diagnosis between 13 and 39 years. Two authors screened the titles, abstracts, and full-text articles and data were extracted and summarized. RESULTS: The search yielded 11,347 articles and 82 met inclusion criteria. Articles included 45 quantitative, 33 qualitative, and four mixed-methods studies. The majority of studies used cross-sectional designs, while BI definitions, theories, models, frameworks, and measures were varied. Studies explored descriptive, psychological, physical, coping, and social factors, with BI being described most often as an outcome rather than a predictor. CONCLUSIONS: Theory-based research that employs a holistic BI definition and uses longitudinal or intervention study designs or a qualitative methodology is needed to better understand the BI experience of AYAs and inform the development of strategies and programs to reduce BI concerns and increase positive body experiences.

PURPOSE: Home-based exercise interventions offer many health benefits; however, the environments that constitute home-based exercise are not well-understood. The purpose of this study was to explore what constitutes the "home" for cancer survivors engaging in home-based exercise and identify factors of the environment that may impact exercise participation. METHODS: We conducted a qualitative exploratory study of cancer survivors receiving a home-based exercise prescription to manage their cancer-related impairments. Semi-structured interviews included photo elicitation to actively involve participants in the interview process and provide opportunities to visually "observe" environments utilized for home-based exercise. RESULTS: Sixteen participants were interviewed (n = 11 women, median age = 53.5, range = 26-74 years) and three themes emerged: (1) reasons for participating in a home-based exercise program; (2) physical environmental influences and preferences; and (3) social environmental influences and preferences. The ability to self-manage exercise and accommodate competing demands, having access to exercise facilities, feeling comfortable exercising without qualified supervision, and a desire for autonomy were reasons home-based exercise programs were preferred. Participants reported that the physical environment influenced their experience with home-based exercise and sub-themes related to a dynamic environment, indoor and outdoor characteristics, and aesthetics were identified. The social environment, with sub-themes associated with the presence of people, social climate, exercise modeling, connection, and exercise support, also related to exercise behavior. CONCLUSION: The findings highlight the influence of the physical and social environment on exercise prescription engagement. They further indicate the need for exercise professionals to consider the environment for exercise when delivering home-based exercise interventions.

The new 2017 diagnostic criteria for hypermobile Ehlers-Danlos Syndrome (hEDS) provide a framework for diagnosing hEDS but are more stringent than the previous Villefranche criteria. Our clinical experience at the GoodHope EDS clinic was that the 2017 criteria left many highly symptomatic patients without a diagnosis of hEDS. We conducted a retrospective cohort study to confirm our clinic experience and assess the accuracy of the 2017 diagnostic criteria for hEDS in patients who had a previous hEDS diagnosis based on the Villefranche criteria. Our study found that 15% (n = 20 of 131) of patients with a prior diagnosis of hEDS met the 2017 diagnostic criteria, and many of the traits used to distinguish hEDS were not significantly more frequent in patients who met 2017 criteria versus those who did not. In both groups objective systemic manifestations were found less frequently than subjective systemic manifestations. Beighton score (BS) as assessed by primary care practitioner was found to be higher than assessment by EDS practitioner in 81% (n = 74 of 91) of cases. Generalized joint hypermobility was confirmed in only 46% (n = 51 of 111) of patients who had a previous diagnosis of hEDS. Higher BS did not correlate with increased number of systemic manifestations in our cohort. Common comorbidities of hEDS were found with similar frequency in those who met 2017 criteria and those who did not. Based on our cohort, the 2017 hEDS diagnostic criteria require refinement to improve its diagnostic accuracy.

OBJECTIVE: The relationship between physical activity (PA) and quality of life (QOL) relative to active treatment for prostate cancer (PCa) has been well-studied; however, little is known about this relationship during active surveillance (AS). Moreover, whether PA is associated with better emotional well-being (EWB) in men with low-risk PCa requires further investigation. Accordingly, we examined the association between self-reported PA and the average change in QOL and EWB over time during AS. METHODS: A total of 630 men on AS were included in this retrospective, longitudinal study from AS initiation until AS discontinuation. Generalized estimated equations were used to determine the association between self-reported PA (independent variable) and QOL and EWB (dependent variables) over time, adjusting for participants' age. RESULTS: QOL was higher over time in active ( ß^ (95%CI) = 1.14 (0.11, 2.16), P = .029) and highly active participants ( ß^ (95%CI) = 1.62 (0.58, 2.67), P = .002) compared to their inactive counterparts. Highly active participants had 55% greater odds of experiencing high EWB relative to inactive participants (OR (95%CI) = 1.55 (1.11, 2.16), P = .010). In men with low EWB at baseline (median = 3 months after diagnosis), the highest levels of PA (>1000 metabolic equivalent-minutes per week) were associated with high EWB over time (OR (95%CI) = 2.17 (1.06, 4.46), P = .034). CONCLUSIONS: These data further support the importance of PA as a supportive care strategy for men on AS. Our findings suggest that engaging in higher volumes of PA post-diagnosis may be beneficial particularly for men exhibiting low emotional well-being early on during AS.

BACKGROUND: The literature reflects considerable heterogeneity in what constitutes home-based exercise interventions. The variability for where and what "home-based" exercise can represent challenges interpretation of findings and appropriate advocacy, referral, or development of these models of care. Therefore, the objective of this review was to provide a comprehensive summary of how home-based exercise is defined and reported in the literature and summarize the range of supportive elements utilized in home-based exercise trials. METHODS: We followed methodology for scoping reviews. Relevant research databases were searched from inception to March 2019. Two reviewers independently screened articles to determine eligibility and extracted terminology used to describe home-based exercise and intervention details for intervention delivery. RESULTS: Of the 9432 records identified, 229 articles met inclusion criteria. Across the literature, exercise interventions were described as home-based if they were completed at-home, outdoors in the neighbourhood, and in community facilities; or in self-selected environments; or if they were unsupervised. Supportive elements for home-based models ranged with respect to the amount of supervision and resources utilized, including the provision of print materials, exercise equipment, telephone support, home visits, and technology. CONCLUSIONS: This review provides a comprehensive summary of strategies previously utilized to deliver home-based exercise interventions in oncology, along with the various definitions of the home-based environment for exercise reported by researchers. Specific recommendations to improve the prescription and reporting of home-based exercise interventions are provided in order to facilitate the delivery, evaluation, and translation of findings into clinical practice.

PURPOSE: Aerobic exercise prescriptions in clinical populations commonly involve target intensities based on cardiopulmonary exercise tests (CPET). CPETs are often discontinued prior to a patient achieving true maximum oxygen consumption (VO2 max) which can adversely affect exercise dose and efficacy monitoring; however, reasons for early discontinuation are poorly reported. Accordingly, we explored the CPET termination reasons in persons with cancer participating in exercise intervention studies. METHODS: This study comprised of an exploratory, descriptive analysis of retrospective CPET data (VO2 and anaerobic threshold) and termination reasons in a convenience sample of people with cancer participating in exercise intervention studies in a single laboratory. CPETs were standardized using the modified Bruce treadmill protocol with expired gas collection and analysis using a metabolic cart. VO2 max was considered "met" when participants demonstrated (a) oxygen consumption plateau or (b) two of the following criteria: rating of perceived exertion ≥ 9/10, respiratory exchange ratio ≥ 1.15, and/or heart rate of 95% of age-predicted maximum. The frequency and distribution of reasons for test termination relative to the number of CPET exposures for the participants were reported. RESULTS: Forty-four participants engaged in exercise studies between February 2016 and March 2018 provided data for the analysis. Participants completed up to three CPETs during this period (total of 78 CPETs in the current analysis). Eighty-six percent of all CPETs were terminated prior to achieving VO2 max verification criteria and no tests resulted in an oxygen consumption plateau. For those that did not demonstrate achievement of VO2 max verification criteria, reasons for discontinuation were distributed as follows: equipment discomfort-49%, volitional peak-36%, and physical discomfort-14.9%. For those who met VO2 max criteria, volitional peak was the most common reason for test termination (45.5%), followed by physical discomfort (36.4%), and equipment discomfort (18.2%). CONCLUSIONS: In our sample of cancer survivors, VO2 max criteria were infrequently met with equipment discomfort being a primary reason for participant-driven test termination. Protocol and equipment considerations are necessary for interpretation and application of CPET findings in clinical practice.

BACKGROUND: National and international bodies acknowledge the benefit of exercise for people with cancer, yet limited accessibility to related programing remains. Given their involvement in managing the disease, cancer centers can play a central role in delivering exercise-oncology services. The authors developed and implemented a clinically integrated exercise-oncology program at a major cancer center and evaluated its effectiveness and participant experience. METHODS: A hospital-based program with prescribed at-home exercise was developed and accepted referrals over a 42-month period (3.5 years). Implementation was conducted in 2 phases: a pilot phase for women with breast cancer and men with genitourinary cancer and a roll-out phase for all patients with cancer. Enrolled patients were assessed and received an exercise prescription as well as a program manual, resistance bands, and a stability ball from a kinesiologist. Program participation and effectiveness were evaluated up to 48 weeks after the baseline assessment using intention-to-treat analyses. Participants in the roll-out phase were asked to complete a program experience questionnaire at the completion of the 48-week follow-up. RESULTS: In total, 112 participants enrolled in the pilot, and 150 enrolled in the roll-out phase. Program attrition to 48 weeks was 48% and 65% in the pilot and roll-out phases, respectively. In participants who consented to research evaluation of their performance, objective and patient-reported measures of functional capacity improved significantly from baseline in both phases. Participants were highly satisfied with the program. CONCLUSIONS: Despite significant drop-out to program endpoints, our cancer-exercise program demonstrated clinically relevant improvement in functional outcomes and was highly appreciated by participants.

PURPOSE: Epidemiologic data suggest that high levels of physical activity (PA) may reduce the risk of disease progression in men with prostate cancer (PCa), but it is unknown whether PA can delay the requirement for definitive treatment for those on active surveillance (AS). We investigated the influence of PA post-diagnosis on AS discontinuation in men with low-risk disease. METHODS: The effect of PA on the time to AS discontinuation was assessed in 421 patients, of whom 107 underwent additional PCa treatment over a median of 2.5 years. RESULTS: Using Cox regression models, we found that PA was not significantly associated with time to curative treatment initiation. Prostate-specific antigen (PSA) most proximal to AS initiation (HR, 1.11; 95% CI 1.03 to 1.21) and the number of positive cores (HR, 1.34; 95% CI 1.12 to 1.61) at diagnosis were associated with a significantly increased risk of discontinuing AS. CONCLUSION: Our findings suggest that PA during AS for PCa does not significantly influence time to curative treatment.

BACKGROUND: Existing evidence demonstrates that 1:1 personal training (PT) improves many adverse effects of androgen deprivation therapy (ADT). Whether less resource-intensive exercise delivery models are as effective remains to be established. We determined the feasibility of conducting a multi-center non-inferiority randomized controlled trial comparing PT with supervised group (GROUP) and home-based (HOME) exercise programs, and obtained preliminary efficacy estimates for GROUP and HOME compared to PT on quality of life (QOL) and physical fitness. METHODS: Men with prostate cancer on ADT were recruited from one of two experienced Canadian centres and randomized 1:1:1 to PT, GROUP, or HOME. Randomization was stratified by length of ADT use and site. Participants completed moderate intensity aerobic and resistance exercises 4-5 days per week for 6 months with a target 150 min per week of exercise. Exercise prescriptions were individualized and progressed throughout the trial. Feasibility endpoints included recruitment, retention, adherence, and participant satisfaction. The efficacy endpoints QOL, fatigue, and fitness (VO2 peak, grip strength, and timed chair stands) in GROUP and HOME were compared for non-inferiority to PT. Descriptive analyses were used for feasibility endpoints. Between-group differences for efficacy endpoints were examined using Bayesian linear mixed effects models. RESULTS: Fifty-nine participants (mean age 69.9 years) were enrolled. The recruitment rate was 25.4% and recruitment was slower than projected. Retention was 71.2%. Exercise adherence as measured through attendance was high for supervised sessions but under 50% by self-report and accelerometry. Satisfaction was high and there was no difference in this measure between all three groups. Between-group differences (comparing both GROUP and HOME to PT) were smaller than the minimum clinically important difference on most measures of QOL, fatigue, and fitness. However, two of six outcomes for GROUP and four of six outcomes for HOME had a > 20% probability of being inferior for GROUP. CONCLUSIONS: Feasibility endpoints were generally met. Both GROUP and HOME interventions in men with PC on ADT appeared to be similar to PT for multiple efficacy outcomes, although conclusions are limited by a small sample size and cost considerations have not been incorporated. Efforts need to be targeted to improving recruitment and adherence. A larger trial is warranted. TRIAL REGISTRATION: ClinicalTrials.gov: NCT02046837 . Date of registration: January 20, 2014.

Physical exercise offers numerous health-related benefits to individuals with cancer. Epidemiologic research has primarily been concerned with conventional exercise training that aligns with the recommendations of 150 min of moderate to vigorous physical activity per week. These recommendations are safe and effective at improving physical and psychosocial outcomes. Given the extensive evidence for generalized physical activity, researchers have begun to explore novel training regimens that may provide additional health benefits and/or improved adherence. Specifically, exercise at higher intensities may offer more or different benefits than conventional training approaches with potentially profound effects on the tumor microenvironment. This commentary focuses on the physiological effects of high-intensity interval training, also known as "HIIT," and its potential antineoplastic properties.

BACKGROUND: Androgen deprivation therapy (ADT) is commonly used to treat prostate cancer. However, side effects of ADT often lead to reduced quality of life and physical function. Existing evidence demonstrates that exercise can ameliorate multiple treatment-related side effects for men on ADT, yet adherence rates are often low. The method of exercise delivery (e.g., supervised group in-centre vs. individual home-based) may be important from clinical and economic perspectives; however, few studies have compared different delivery models. Additionally, long-term exercise adherence and an understanding of predictors of adherence are critical to achieving sustained benefits, but such data are lacking. The primary aim of this multi-centre phase III non-inferiority randomized controlled trial is to determine whether a home-based delivery model is non-inferior to a group-based delivery model in terms of benefits in fatigue and fitness in this population. Two other key aims include examining cost-effectiveness and long-term adherence. METHODS: Men diagnosed with prostate cancer of any stage, starting or continuing on ADT for at least 6 months, fluent in English, and living close to a study centre are eligible. Participants complete five assessments over 12 months (baseline and every 3 months during the 6-month intervention and 6-month follow-up phases), including a fitness assessment and self-report questionnaires. Biological outcomes are collected at baseline, 6, and 12 months. A total of 200 participants will be randomized in a 1:1 fashion to supervised group training or home-based training supported by smartphones, health coaches, and Fitbit technology. Participants are asked to complete 4 to 5 exercise sessions per week, incorporating aerobic, resistance and flexibility training. Outcomes include fatigue, quality of life, fitness measures, body composition, biological outcomes, and program adherence. Cost information will be obtained using patient diary-based self-report and utilities via the EQ-5D. DISCUSSION: To disseminate publicly funded exercise programs widely, clinical efficacy and cost-effectiveness have to be demonstrated. The goals of this trial are to provide these data along with an increased understanding of adherence to exercise among men with prostate cancer receiving ADT. TRIAL REGISTRATION: The trial has been registered at clinicaltrials.gov (Registration # NCT02834416 ). Registration date was June 2, 2016.

PURPOSE: High complication rates following colorectal surgery render many patients unable to fully regain functional capacity, thus seriously compromising quality of life. The aim of this study was to assess whether a 4-week trimodal prehabilitation program (exercise, nutritional supplementation, and counseling on relaxation techniques), implemented during the preoperative period, is sufficient to modify exercise behaviors and improve functional capacity of elderly patients scheduled for colorectal cancer surgery. METHODS: Patients were assigned to either a prehabilitation (PREHAB; n = 57) or matched time control group (CTRL; n = 59). Over the 4-week period prior to surgery, patients in PREHAB participated in a trimodal prehabilitation program. Patients in CTRL received the same program but only postoperatively. The Community Healthy Activities Model Program for Seniors (CHAMPS) questionnaire was used to measure physical activity levels, while the 6-min walk test (6MWT) was used for assessment of functional walking capacity. Measurements were collected at baseline and at the time of surgery. RESULTS: Over the preoperative period, patients in PREHAB significantly increased the amount of moderate- and vigorous-intensity physical activities that they performed. PREHAB patients also demonstrated a greater improvement in 6MWT compared to CTRL. At the time of surgery, a greater proportion of patients in PREHAB met current physical activity guidelines, as compared to CTRL. CONCLUSIONS: These findings highlight the positive effects of a trimodal prehabilitation program on patients' physical activity levels and functional walking capacity and demonstrate that modifying exercise behaviors and improving physical function within the 4-week preoperative period are an achievable goal.

Literature regarding the development of adolescent and young adult (AYA) cancer programs has been dominantly informed by pediatric centers and practitioners. However, the majority of young adults are seen and treated at adult cancer centers, in which cancer volumes afford the development of innovative supportive care services. Although the supportive care services in adult cancer centers are helpful to AYAs, some of the most prominent and distinct issues faced by AYAs are not adequately addressed through these services alone. This article describes how the AYA Program at Princess Margaret Cancer Centre has collaborated with existing supportive care services in addition to supplying its own unique services to meet the comprehensive needs of AYAs in the domains of: symptom management (sexuality and fatigue), behavior modification (return to work and exercise), and health services (advanced cancer and survivorship). These collaborations are augmented by patient education interventions and timely referrals. The objective of this article was to assist other centers in expanding existing services to address the needs of AYA patients with cancer.
