Background: While therapeutically effective, chemoradiotherapy treatment for high-grade glioma (glioblastoma) is often accompanied by side effects. Exercise has been demonstrated to alleviate the adverse effects of such treatments in other cancers. We aimed to evaluate the feasibility and preliminary efficacy of supervised exercise incorporating autoregulation. Methods: Thirty glioblastoma patients were recruited, five declined exercise and 25 were provided with a multimodal exercise intervention for the duration of their chemoradiotherapy treatment. Patient recruitment, retention, adherence to training sessions and safety were evaluated throughout the study. Physical function, body composition, fatigue, sleep quality, and quality of life were evaluated before and after the exercise intervention. Results: Eight of the 25 participants commencing exercise withdrew prior to completion of the study (32%). Seventeen patients (68%) demonstrated low to high adherence (33%–100%) and exercise dosage compliance (24%–83%). There were no reported adverse events. Significant improvements were observed for all trained exercises and lower limb muscle strength and function with no significant changes observed for any other physical function, body composition, fatigue, sleep, or quality of life outcomes. Conclusions: Only half of glioblastoma patients recruited were willing or able to commence, complete or meet minimum dose compliance for the exercise intervention during chemoradiotherapy indicating the intervention evaluated may not be feasible for part of this patient cohort. For those who were able to complete the exercise program, supervised, autoregulated, multimodal exercise was safe and significantly improved strength and function and may have prevented deterioration in body composition and quality of life.

Purpose: Exercise has been underutilized in people with advanced or incurable cancer despite the potential to improve physical function and reduce psychosocial morbidity, especially for people with bone metastases because of concerns over skeletal complications. The International Bone Metastases Exercise Working Group (IBMEWG) was formed to develop best practice recommendations for exercise programming for people with bone metastases on the basis of published research, clinical experience, and expert opinion. Methods: The IBMEWG undertook sequential steps to inform the recommendations: (1) modified Delphi survey, (2) systematic review, (3) cross-sectional survey to physicians and nurse practitioners, (4) in-person meeting of IBMEWG to review evidence from steps 1-3 to develop draft recommendations, and (5) stakeholder engagement. Results: Recommendations emerged from the contributing evidence and IBMEWG discussion for pre-exercise screening, exercise testing, exercise prescription, and monitoring of exercise response. Identification of individuals who are potentially at higher risk of exercise-related skeletal complication is a complex interplay of these factors: (1) lesion-related, (2) cancer and cancer treatment–related, and (3) the person-related. Exercise assessment and prescription requires consideration of the location and presentation of bone lesion(s) and should be delivered by qualified exercise professionals with oncology education and exercise prescription experience. Emphasis on postural alignment, controlled movement, and proper technique is essential. Conclusion: Ultimately, the perceived risk of skeletal complications should be weighed against potential health benefits on the basis of consultation between the person, health care team, and exercise professionals. These recommendations provide an initial framework to improve the integration of exercise programming into clinical care for people with bone metastases.

Background: Radiotherapy (RT) can lead to cancer-related fatigue (CRF) and decreased health-related quality of life (HRQoL) in breast cancer patients. The purpose of this trial was to examine the feasibility and efficacy of a home-based resistance and aerobic exercise intervention for reducing CRF and improving HRQoL in breast cancer patients during RT. Methods: Women with breast cancer (N = 106) commencing RT were randomized to 12 weeks of home-based resistance and aerobic exercise (EX) or usual care/control (CON). The primary endpoint was CRF, with secondary endpoints of HRQoL, sleep duration and quality, and physical activity. Measurements were undertaken prior to RT, at completion of RT (~ 6 weeks), at completion of the intervention (12 weeks), and 6 and 12 months after RT completion, while CRF was also measured weekly during RT. Results: Eighty-nine women completed the study (EX = 43, CON = 46). Over the 12-week intervention, EX completed 1 – 2 resistance training sessions and accumulated 30–40 min of aerobic exercise weekly. For CRF, EX had a quicker recovery both during and post-RT compared to CON (p < 0.05). Moreover, there was a significant difference in HRQoL between groups at RT completion, with HRQoL unchanged in CON and higher in EX (p < 0.05). There was no change in sleep duration or quality for either group and there were no exercise-related adverse effects. Conclusions: Home-based resistance and aerobic exercise during RT is safe, feasible, and effective in accelerating CRF recovery and improving HRQoL. Improvements in CRF and HRQoL for these patients can be achieved with smaller exercise dosages than stated in the generic recommendations for breast cancer.

Physical activity (PA) has shown to mitigate many of the common side effects of cancer treatments. The promotion of PA by health care professionals (HCPs) can facilitate the adoption of PA by patients with cancer. Drawing on an empirical ethics of care approach, this article explores how the delivery of PA recommendations is done within clinical cancer care. Based on 175 observations of consultations between doctors, nurses and patients and interviews with 27 doctors and nurses, we show how delivering PA recommendations was related to four care practices: “adjusting information to match the patient’s needs and situation,” “managing current and anticipated treatment-induced side effects,” “using visual aids and quantifiable data,” and “maintaining a good relationship between the patient and the HCP.” Drawing on these findings, we discuss strategies to strengthen the delivery of PA recommendations in clinical cancer care.

Background: Exercise has the potential to improve physical function and quality of life in individuals with bone metastases but is often avoided due to safety concerns. This systematic review summarizes the safety, feasibility and efficacy of exercise in controlled trials that include individuals with bone metastases. Methods: MEDLINE, Embase, Pubmed, CINAHL, PEDro and CENTRAL databases were searched to July 16, 2020. Results: A total of 17 trials were included incorporating aerobic exercise, resistance exercise or soccer interventions. Few (n = 4, 0.5%) serious adverse events were attributed to exercise participation, with none related to bone metastases. Mixed efficacy results were found, with exercise eliciting positive changes or no change. The majority of trials included an element of supervised exercise instruction (n = 16, 94%) and were delivered by qualified exercise professionals (n = 13, 76%). Conclusions: Exercise appears safe and feasible for individuals with bone metastases when it includes an element of supervised exercise instruction.

The purpose of this study was to investigate the validity and reliability of methods for determining barbell displacement during heavy back squats. Twelve well-trained rugby union players (mean ± SD 1 repetition maximum [1RM] 90° squat = 196.3 ± 29.2 kg) completed 2 sets of 2 repetitions at 70, 80, and 90% of 1RM squats. Barbell displacement was derived from 3 methods across 4 load categories (120–129, 140–149, 160–169, and 180–189 kg) including: a (a) linear position transducer (LPT) attached 65 cm left of barbell center, (b) 3D motion analysis tracking of markers attached to either end of a barbell, and (c) cervical marker (C7) (criterion measurement). Validity was calculated using the typical error of the estimate as a coefficient of variation (CV%) ±90% confidence interval (CI), mean bias as a percentage, and the Pearson product moment correlation (r). Intraday reliability was calculated using the intraclass correlation coefficient and the typical error expressed as a percentage of CV% ±90% (CI). Mean displacement for C7, LPT, and the barbell ends was 520, 529, and 550–564 mm, respectively. Validity of the LPT compared with the criterion was acceptable (CV% = 2.1–3.0; bias = 0.9–1.5%; r = 0.96–0.98), whereas that of the barbell ends was less (CV% = 2.7–7.5; bias = 4.9–11.2%; r = 0.71–0.97). The CV% reliability of the C7 marker across the load categories was 6.6%, the LPT 6.6%, and the barbell ends between 5.9 and 7.2%. Despite reliable measures, overestimation of displacement occurs as the tracking location moves to the barbell ends in weighted back squats. The LPT demonstrated high validity to the criterion and high trial-to-trial reliability.

OBJECTIVES: To examine whether it is more efficacious to commence exercise medicine in men with prostate cancer at the onset of androgen-deprivation therapy (ADT) rather than later on during treatment to preserve bone and soft-tissue composition, as ADT results in adverse effects including: reduced bone mineral density (BMD), loss of muscle mass, and increased fat mass (FM). PATIENTS AND METHODS: In all, 104 patients with prostate cancer, aged 48-84 years initiating ADT, were randomised to immediate exercise (IMEX, n = 54) or delayed exercise (DEL, n = 50) conditions. The former consisted of 6 months of supervised resistance/aerobic/impact exercise and the latter comprised 6 months of usual care followed by 6 months of the identical exercise programme. Regional and whole body BMD, lean mass (LM), whole body FM and trunk FM, and appendicular skeletal muscle (ASM) were assessed by dual X-ray absorptiometry, and muscle density by peripheral quantitative computed tomography at baseline, and at 6 and 12 months. RESULTS: There was a significant time effect (P < 0.001) for whole body, spine and hip BMD with a progressive loss in the IMEX and DEL groups, although lumbar spine BMD was largely preserved in the IMEX group at 6 months compared with the DEL group (-0.4% vs -1.6%). LM, ASM, and muscle density were preserved in the IMEX group at 6 months, declined in the DEL group at 6 months (-1.4% to -2.5%) and then recovered at 12 months after training. FM and trunk FM increased (P < 0.001) over the 12-month period in the IMEX (7.8% and 4.5%, respectively) and DEL groups (6.5% and 4.3%, respectively). CONCLUSIONS: Commencing exercise at the onset of ADT preserves lumbar spine BMD, muscle mass, and muscle density. To avoid treatment-related adverse musculoskeletal effects, exercise medicine should be prescribed and commenced at the onset of ADT.

Background Mental illness is a leading cause of the global burden of disease. Physical activity (PA) can improve physical and mental health outcomes for people with mental illness, yet routine implementation of PA within standard care remains ad-hoc. The reasons for this are unclear, although the dissonance between the evidence produced in research settings and that needed in real-world environments may be key. Purpose To explore the effectiveness of PA interventions as a treatment for mental illness. We synthesised past systematic reviews and meta-analyses. Methods We conducted a systematic review of reviews from database inception to 09/2017. Reviews were included that considered any mental health condition (diagnosed via standardised criteria) and where PA interventions were a stand-alone or adjunctive treatment. Effectiveness was defined as outcomes that are important in real-world healthcare (i.e. expected clinical outcomes, intervention safety and cost). Results From 4008 hits, 33 reviews (including 155 unique studies) were included and 32 reported that PA has a positive effect on at least one main outcome of interest (symptoms of mental illness, quality of life and/or physical health). There was inconsistent reporting of adverse events and no cost data was identified. The AMSTAR quality rating suggests inconsistencies in review quality. Conclusions The research agenda must expand to report on outcomes that can support evidence translation efforts (i.e. cost and adverse events). Without such a shift, research in PA and mental health may fail to achieve translation to routine care and may have limited impact on patient outcomes.

Depression in men with prostate cancer is a significant and complex issue that can challenge clinicians' diagnostic efforts. The objective of the current study was to evaluate prototypic and male-specific depression symptoms and suicidal ideation in men with a diagnosis of prostate cancer relative to those with and without comorbidity. The Patient Health Questionnaire-9 (PHQ-9) and Male Depression Risk Scale-22 (MDRS-22) were completed online along with demographic and background variables by 100 men with a diagnosis of prostate cancer ( n = 54 prostatectomy, n = 33 receiving active treatment). Hierarchical logistic regression was used to examine recent (past 2 weeks) suicide ideation. Over one-third of the sample (38%) reported a comorbidity, and this group had significantly higher total depression scores on the PHQ-9 (Cohen's d = 0.65), MDRS-22 emotion suppression ( d = 0.35), and drug use subscales ( d = 0.38) compared to respondents without comorbidity. A total of 14% reported recent suicidal ideation, of which 71.4% of cases were identified by the PHQ-9 "moderate" cut-off, and 85.7% of cases were identified by the MDRS-22 "elevated" cut-off. After control variables, MDRS-22 subscales accounted for 45.1% of variance in recent suicidal ideation. While limited by the exclusive use of self-report data, findings point to the potential benefits of evaluating male-specific symptoms as part of depression and suicide risk screening in men with prostate cancer and the need to be mindful of the heightened risk for depression among men with prostate cancer who have comorbidity.

The purpose of this study was to investigate the feasibility and preliminary efficacy of a pragmatic distance-based intervention designed to increase physical activity (PA) participation in lung cancer survivors. Fourteen lung cancer survivors were recruited via invitation from the State Cancer Registry to join a 12-week PA intervention of print materials paired with brief telephone follow-up. Outcome measures of feasibility, PA participation and quality of life (QoL) were assessed at baseline, post-intervention and follow-up via telephone interview. Eligibility, recruitment and attrition rates were 16%, 58% and 29% respectively. No adverse events were reported; however, pain scores worsened following the intervention (median change −3.6, IQR −8.0, 0.0). Average intervention adherence was 91% with low median ratings of participation burden (i.e., all items 1/7) and high trial evaluation (i.e., all items 7/7). Post-intervention, median change in self-reported moderate and vigorous PA was 84 min (IQR −22, 188), and several domains of QoL improved. However, for both of these outcomes, improvements were not maintained at follow-up. Our findings suggest that this pragmatic distance-based intervention was safe, had good adherence rates, and indicate potential for improving short-term PA and QoL in lung cancer survivors. Additional strategies are needed to improve other indicators of feasibility, particularly recruitment, retention and long-term maintenance of improvements.

Introduction: Clinical research has established exercise as a safe and effective intervention to counteract the adverse physical and psychological effects of cancer and its treatment. This article summarises the position of the Clinical Oncology Society of Australia (COSA) on the role of exercise in cancer care, taking into account the strengths and limitations of the evidence base. It provides guidance for all health professionals involved in the care of people with cancer about integrating exercise into routine cancer care. Main recommendations: COSA calls for: • exercise to be embedded as part of standard practice in cancer care and to be viewed as an adjunct therapy that helps counteract the adverse effects of cancer and its treatment; • all members of the multidisciplinary cancer team to promote physical activity and recommend that people with cancer adhere to exercise guidelines; and • best practice cancer care to include referral to an accredited exercise physiologist or physiotherapist with experience in cancer care. Changes in management as a result of the guideline: COSA encourages all health professionals involved in the care of people with cancer to: • discuss the role of exercise in cancer recovery; • recommend their patients adhere to exercise guidelines (avoid inactivity and progress towards at least 150 minutes of moderate intensity aerobic exercise and two to three moderate intensity resistance exercise sessions each week); and • refer their patients to a health professional who specialises in the prescription and delivery of exercise (ie, accredited exercise physiologist or physiotherapist with experience in cancer care).
