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 \u3e 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

Device assessed activity behaviours in patients with indwelling pleural catheter: A sub-study of the Australasian Malignant PLeural Effusion (AMPLE)-2 randomized trial

Background and Objective: Device-assessed activity behaviours are a novel measure for comparing intervention outcomes in patients with malignant pleural effusion (MPE). Australasian Malignant PLeural Effusion (AMPLE)-2 was a multi-centre clinical trial where participants with MPE treated with an indwelling pleural catheter were randomized to daily (DD) or symptom-guided (SGD) drainage for 60-days. Our aim was to describe activity behaviour patterns in MPE patients, explore the impact of drainage regimen on activity behaviours and examine associations between activity behaviours and quality of life (QoL). Methods: Following randomization to DD or SGD, participants enrolled at the lead site (Perth) completed accelerometry assessment. This was repeated monthly for 5-months. Activity behaviour outcomes were calculated as percent of daily waking-wear time and compared between groups (Mann–Whitney U test; Median [IQR]). Correlations between activity behaviour outcomes and QoL were examined. Results: Forty-one (91%) participants provided ≥ 1 valid accelerometry assessment (DDn = 20, SGD n = 21). Participants spent a large proportion of waking hours sedentary (72%–74% across timepoints), and very little time in moderate-to-vigorous physical activity ( \u3c 1% across timepoints). Compared to SGD group, DD group had a more favourable sedentary-to-light ratio in the week following randomization (2.4 [2.0–3.4] vs. 3.2 [2.4–6.1]; p = 0.047) and at 60-days (2.0 [1.9–2.9] vs. 2.9 [2.8–6.0]; p = 0.016). Sedentary-to-light ratio was correlated with multiple QoL domains at multiple timepoints. Conclusion: Patients with MPE are largely sedentary. Preliminary results suggest that even modest differences in activity behaviours favouring the DD group could be meaningful for this clinical population. Accelerometry reflects QoL and is a useful outcome measure in MPE populations

The effects of home-based exercise therapy for breast cancer-related fatigue induced by radical radiotherapy

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 \u3c 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 \u3c 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

Randomised placebo-controlled cross-over study examining the role of anamorelin in mesothelioma (The ANTHEM study): Rationale and protocol

Introduction Cachexia is common in malignant mesothelioma (MM); half of patients have malnutrition and low skeletal muscle mass. Malnourished patients have worse quality of life (QoL). Weight loss is strongly associated with poor survival. Anamorelin is an oral ghrelin receptor agonist that improves appetite, body weight and QoL in advanced cancer. The aim of this study is to examine the efficacy of anamorelin in improving appendicular skeletal muscle mass (ASM) and patient-reported outcomes in patients with MM with cachexia. Methods and analysis A single-centre, phase II, randomised, placebo-controlled cross-over pilot study with 28-day treatment periods and 3-day washout. Forty patients will be randomised. Primary outcome is change in ASM relative to height measured by dual energy X-ray absorptiometry at end of period 1. Secondary outcomes include cancer-specific and cachexia-related QoL, objective physical activity, dietary intake and adverse events. Eligible patients will have confirmed MM, Eastern Cooperative Oncology Group 0-2, expected survival \u3e 3 months and cachexia (defined as \u3e 5% weight loss in 6 months or body mass index \u3c 20 kg/m 2 with weight loss \u3e2%).

Study protocol: Investigating the feasibility of a hybrid delivery of home-based cluster set resistance training for individuals previously treated for lung cancer

Background: Symptom burden remains a critical concern for individuals with non-small cell lung cancer (NSCLC) following the completion of treatment. The most common symptom clusters, dyspnea (shortness of breath) and fatigue, can contribute to physical decline, reductions in quality of life, and a higher risk of comorbidities and mortality. Dyspnea is a primary limiter of exercise capacity in individuals with lung cancer, resulting in exercise avoidance and an accelerated physical decline. As such, designing resistance training with cluster sets to mitigate symptoms of dyspnea and fatigue may result in improved exercise tolerance. Thus, maintaining the exercise stimulus via cluster sets, combined with improved tolerance of the exercise, could result in the maintenance of physical function and quality of life. The purpose of this study is to investigate the feasibility and preliminary efficacy of a hybrid-delivery home-based cluster-set resistance training program in individuals with NSCLC. Methods: Individuals with NSCLC (n = 15), within 12 months of completion of treatment, will be recruited to participate in this single-arm feasibility trial. Participants will complete 8 weeks of home-based resistance training designed to minimize dyspnea and fatigue. The hybrid delivery of the program will include supervised sessions in the participants’ home and virtual supervision via video conferencing. The primary outcome of feasibility will be quantified by recruitment rates, retention, acceptability, and intervention fidelity. Exploratory outcomes (dyspnea, fatigue, quality of life, physical function, and body composition) will be assessed pre- and post-intervention. Discussion: This study will provide important data on the feasibility of delivering this intervention and inform procedures for a future randomized controlled trial. Trial registration: Record not yet publi

Associations of physical activity and quality of life in parapneumonic effusion patients

Introduction Little is known about activity behaviours and quality of life (QoL) of patients with parapneumonic pleural effusions (PPE) after hospital discharge. This study is a secondary analysis of a randomised trial (dexamethasone versus placebo) for hospitalised patients with PPE. We: 1) described the patients’ activity behaviour patterns and QoL measured at discharge and at 30 days post-discharge; and 2) examined the association between activity behaviours and QoL scores. Methods Activity behaviour (7-day accelerometry; Actigraph GT3X+) and QoL (Medical Outcomes Study Short-Form 36) were assessed. Repeated measures analysis of covariance controlling for baseline values and a series of linear regression models were undertaken. Results 36 out of 53 eligible participants completed accelerometry assessments. Despite modest increases in light physical activity (+7.5%) and some domains of QoL ( \u3e 2 points) from discharge to 30 days post-discharge, patients had persistently high levels of sedentary behaviour ( \u3e 65% of waking wear time) and poor QoL ( ⩽ 50 out of 100 points) irrespective of treatment group ( p=0.135–0.903). Increasing moderate-to-vigorous physical activity was associated with higher scores on most QoL domains ( p=0.006–0.037). Linear regression indicates that a clinically important difference of 5 points in physical composite QoL score can be achieved by reallocating 16.1 min·day−1 of sedentary time to moderate-to-vigorous physical activity. Conclusion Patients with PPE had low levels of physical activity and QoL at discharge and 30 days post-discharge irrespective of treatment. Moderate-to-vigorous physical activity participation was associated with higher QoL scores. Increasing moderate-to-vigorous physical activity following discharge from the hospital may be associated with improvements in QoL. © The authors 2023

Sedentary behaviour, physical activity, and their associations with health outcomes at the time of diagnosis in people with inoperable lung cancer

This study aimed to examine sedentary behaviour (SB), physical activity (PA) and their associations with health-related measures at the time of diagnosis in people with inoperable lung cancer. People newly diagnosed with inoperable lung cancer were invited to participate in the study and asked to wear an accelerometer for seven consecutive days. Variables analysed included time spent in SB, light intensity PA (LIPA) and moderate-to-vigorous intensity PA (MVPA). Daily steps were also recorded. Data on symptoms, health-related quality of life (HRQoL), hand grip force, comorbidities and lung function were collected. Of the 120 patients referred to the study, 89 (74 %) consented to participate, and SB/PA data were available for 79 (age 71 ± 11 years; 29 females). Participants spent 71 % of their waking time in SB, 28 % in LIPA and 1% in MVPA. Regression models demonstrated that increased SB was associated with more symptoms of fatigue and dyspnoea (p ≤ 0.02 for both), poorer HRQoL (general health and physical component score; p ≤ 0.02 for all) and lower hand grip force. For PA variables, higher daily step count was associated with better scores in all health-related measures (p \u3c 0.05 for all). LIPA was associated with more health-related outcomes than MVPA. These findings may guide future interventions in this population

Exercise Preserves Physical Function in Prostate Cancer Patients with Bone Metastases

The presence of bone metastases has excluded participation of cancer patients in exercise interventions and is a relative contraindication to supervised exercise in the community setting due to concerns of fragility fracture. We examined the efficacy and safety of a modular multi-modal exercise program in prostate cancer patients with bone metastases.Between 2012 and 2015, 57 prostate cancer patients (70.0±8.4 years; BMI 28.7±4.0 kg/m) with bone metastases (pelvis 75.4%, femur 40.4%, rib/thoracic spine 66.7%, lumbar spine 43.9%, humerus 24.6%, other sites 70.2%) were randomised to multi-modal supervised aerobic, resistance and flexibility exercises undertaken thrice weekly (EX, n=28) or usual care (CON, n=29) for 3 months. Physical function subscale of the SF-36 was the primary endpoint as an indicator of patient-rated physical functioning. Secondary endpoints included objective measures of physical function, lower body muscle strength, body composition and fatigue. Safety was assessed by recording the incidence and severity of any adverse events, skeletal complications, and bone pain throughout the intervention.There was a significant difference between groups for self-reported physical functioning (3.2 points, 95% CI 0.4-6.0 points; p=0.028) and lower body muscle strength (6.6 kg, 95% CI 0.6-12.7; p =0.033) at 3 months favouring EX. However, there was no difference between groups for lean mass (p=0.584), fat mass (p=0.598), or fatigue (p=0.964). There were no exercise-related adverse events or skeletal fractures and no differences in bone pain between EX and CON (p=0.507).Multi-modal modular exercise in prostate cancer patients with bone metastases led to self-reported improvements in physical function and objectively measured lower body muscle strength with no skeletal complications or increased bone pain.This is an open-access article distributed under the terms of the Creative Commons Attribution-Non Commercial-No Derivatives License 4.0 (CCBY-NC-ND), where it is permissible to download and share the work provided it is properly cited.

Randomized controlled trial of the effects of aerobic exercise on physical functioning and quality of life in lymphoma patients

Purpose Lymphoma patients commonly experience declines in physical functioning and quality of life (QoL) that may be reversed with exercise training. Patients and Methods We conducted a randomized controlled trial in Edmonton, Alberta, Canada, between 2005 and 2008 that stratified 122 lymphoma patients by major disease type and current treatment status and randomly assigned them to usual care (UC; n 62) or 12 weeks of supervised aerobic exercise training (AET; n 60). Our primary end point was patient-rated physical functioning assessed by the Trial Outcome Index-Anemia. Secondary end points were overall QoL, psychosocial functioning, cardiovascular fitness, and body composition. Results Follow-up assessment for our primary end point was 96% (117 of 122) at postintervention and 90% (110 of 122) at 6-month follow-up. Median adherence to the supervised exercise program was 92%. At postintervention, AET was superior to UC for patient-rated physical functioning (mean group difference, 9.0; 95% CI, 2.0 to 16.0; P .012), overall QoL (P .021), fatigue (P .013), happiness (P .004), depression (P .005), general health (P .001), cardiovascular fitness (P .001), and lean body mass (P .008). Change in peak cardiovascular fitness mediated the change in patient-rated physical functioning. AET did not interfere with chemotherapy completion rate or treatment response. At 6-month follow-up, AET was still borderline or significantly superior to UC for overall QoL (P .054), happiness (P .034), and depression (P .009) without an increased risk of disease recurrence/progression. Conclusion AET significantly improved important patient-rated outcomes and objective physical functioning in lymphoma patients without interfering with medical treatments or response. Exercise training to improve cardiovascular fitness should be considered in the management of lymphoma patients

Steroid therapy and outcome of parapneumonic pleural effusions (STOPPE): Study protocol for a multicenter, double-blinded, placebo-controlled randomized clinical trial

BACKGROUND: Community-acquired pneumonia (CAP) is a major global disease. Parapneumonic effusions often complicate CAP and range from uninfected (simple) to infected (complicated) parapneumonic effusions and empyema (pus). CAP patients who have a pleural effusion at presentation are more likely to require hospitalization, have a longer length of stay and higher mortality than those without an effusion. Conventional management of pleural infection, with antibiotics and chest tube drainage, fails in about 30% of cases. Several randomized controlled trials (RCT) have evaluated the use of corticosteroids in CAP and demonstrated some potential benefits. Importantly, steroid use in pneumonia has an acceptable safety profile with no adverse impact on mortality. A RCT focused on pediatric patients with pneumonia and a parapneumonic effusion demonstrated shorter time to recovery. The effects of corticosteroid use on clinical outcomes in adults with parapneumonic effusions have not been tested. We hypothesize that parapneumonic effusions develop from an exaggerated pleural inflammatory response. Treatment with systemic steroids may dampen the inflammation and lead to improved clinical outcomes. The steroid therapy and outcome of parapneumonic pleural effusions (STOPPE) trial will assess the efficacy and safety of systemic corticosteroid as an adjunct therapy in adult patients with CAP and pleural effusions. METHODS: STOPPE is a pilot multicenter, double-blinded, placebo-controlled RCT that will randomize 80 patients with parapneumonic effusions (2:1) to intravenous dexamethasone or placebo, administered twice daily for 48 hours. This exploratory study will capture a wide range of clinically relevant endpoints which have been used in clinical trials of pneumonia and/or pleural infection; including, but not limited to: time to clinical stability, inflammatory markers, quality of life, length of hospital stay, proportion of patients requiring escalation of care (thoracostomy or thoracoscopy), and mortality. Safety will be assessed by monitoring for the incidence of adverse events during the study. DISCUSSION: STOPPE is the first trial to assess the efficacy and safety profile of systemic corticosteroids in adults with CAP and pleural effusions. This will inform future studies on feasibility and appropriate trial endpoints. TRIAL REGISTRATION: ACTRN1261800094720
