An update of controlled physical activity trials in cancer survivors: a systematic review and meta-analysis

A Theory and Evidence-Informed e-Cycling Intervention for Individuals Diagnosed With Cancer: Development Study

BACKGROUND

Physical activity engagement following a cancer diagnosis is positively associated with survival, reduced risk of disease recurrence, and reduced cancer-specific and all-cause mortality. However, rates of physical activity engagement are low among individuals diagnosed with and being treated for breast cancer or prostate cancer.

OBJECTIVE

The purpose of this study was to describe the systematic process of developing an e-cycling intervention aimed at increasing physical activity among individuals living with prostate cancer or breast cancer and outline the key components to be implemented.

METHODS

The Medical Research Council guidance for developing complex interventions and the Behaviour Change Wheel were used to guide intervention development. Information was gathered from the literature and through discussions with end users to understand factors influencing e-cycling. These factors were mapped onto the Theoretical Domains Framework to identify potential mechanisms of action. Behavior change techniques were selected from theory and evidence to develop intervention content. Interested parties, including cycling instructors, end users, and behavior change experts, reviewed and refined the intervention.

RESULTS

Anticipated barriers and facilitators to e-cycling engagement were mapped onto 11 of the 14 domains of the Theoretical Domains Framework. A total of 23 behavior change techniques were selected to target these domains over 4 one-to-one e-cycling sessions delivered by trained cycling instructors in the community. Cycling instructors were provided a 3-hour classroom training session on delivering the intervention and a 3-hour practical session with feedback. The outcome of this work is a theory and evidence-informed intervention aimed at promoting e-cycling behavior among individuals being treated for breast cancer or prostate cancer, which is currently being implemented and evaluated.

CONCLUSIONS

Transparent intervention development and reporting of content is important for comprehensively examining intervention implementation. The implementation of this intervention package is currently being evaluated in a pilot randomized controlled trial. If the intervention is found to be effective and the content and delivery are acceptable, this intervention will form a basis for the development of e-cycling interventions in other survivors of cancer.

Cardio-Oncology: A New Discipline in Medicine and Its Relevance to Hematology

Cardio-oncology, a burgeoning subspecialty, addresses the complex interplay between cardiology and oncology, particularly in light of increased cardiovascular (CV) disease mortality in cancer patients. This review provides a comprehensive overview of cardio-oncology with a focus on the therapies used in hematological malignancies. We explore the bidirectional relationship between heart failure and cancer, emphasizing the need for collaborative care. The review discusses risk stratification, highlighting the importance of baseline CV risk assessment and personalized surveillance regimens. Primary and secondary prevention strategies, including pharmacological interventions, are outlined. The review also delves into the cardiotoxicity associated with hematological cancer therapies, focusing on anthracyclines, Bruton kinase inhibitors, BCR-ABL tyrosine kinase inhibitors, CAR-T cell therapy, immune checkpoint inhibitors, multiple myeloma treatments, and hematopoietic stem cell transplantation. We then highlight the high risk of venous and arterial thromboembolisms in cancer patients and the challenges of anticoagulation management in cardio-oncology. Finally, the review touches on the importance of long-term follow-up and appropriate screening in cancer survivors at high risk of CV morbidity and mortality, based on their CV risk profile and the type and dose of cardiotoxic therapies they received such as anthracyclines or high radiation doses.

Physical activities aid in tumor prevention: A finite element study of bio-heat transfer in healthy and malignant breast tissues

The objective of the present research is to explore the temperature diffusion in healthy and cancerous tissues, with a specific focus on how physical activity impacts on the weakening of breast tumors. Previous research lacked numerical analysis regarding the effectiveness of physical activity in tumor prevention or attenuation, prompting an investigation into the mechanism behind physical activity and tumor prevention from a bio-heat transfer perspective. The study employs a realistic model of human breasts and tumors in COMSOL Multiphysics® to analyze temperature distribution by utilizing Penne's bio-heat equation. The research examines their influence on tissue temperature by varying tumor diameter (10-20 mm) and exercise intensities (such as walking speeds and other activities like carpentry, swimming, and marathon running). Results demonstrate that cancerous tissues generate notably more heat than normal tissues at rest and during physical activity. Smaller tumors exhibit higher temperatures during exercise, emphasizing the significance of tumor size in treatment effectiveness. Tumor temperatures range between 40 and 43.2 °C, while healthy tissue temperatures remain below 41 °C during physical activity. High-intensity exercises, particularly swimming, walking at 1.8 m/s, and marathon running, display a therapeutic effect on tumors, increasing effectiveness with intensity. The temperatures of healthy and malignant tissues rise noticeably due to constant metabolic heat and decreased blood flow. The study also identifies the optimal duration of high-intensity exercise, recommending at least 20 min for optimal therapeutic outcomes. The outcomes of this research would help individuals, doctors, and cancer researchers understand and weaken malignant tissues.

Effect of resistance exercise on physical fitness, quality of life, and fatigue in patients with cancer: a systematic review

Objective

The purpose of this study is to conduct a systematic review to assess the effects of different forms of resistance exercises (resistance exercise, resistance exercise combined with aerobic exercise, and resistance exercise combined with other exercises) on physical fitness, quality of life (QOL), and fatigue of patients with cancer.

Methods

We conducted a systematic review using the Cochrane Handbook for Systematic Reviews of Interventions guidelines. We searched PubMed, Web of Science, and Scopus databases for the studies from the establishment of the database to September 2023, including randomized controlled trials and clinical trials that evaluated the effects of different resistance exercise on physical fitness, QOL, and fatigue in all patients with cancer. Two reviewers independently assessed the quality of all the included studies using the Cochrane Handbook for Systematic Reviews of Interventions and MINORS scale. We divided the intervention into three types: resistance exercise, resistance exercise combined with aerobic exercise, and resistance exercise combined with other exercises.

Results

In total, 48 studies (3,843 participants) met the inclusion criteria. The three exercise intervention forms have significant effects on physical fitness and QOL, but the improvement effect on fatigue is not clear. A total of 34 studies reported significant and beneficial effects of resistance exercise on physical fitness across all types of cancer. There were 28 studies that reported significant or borderline improvement effects of resistance on QOL, and only 10 studies reported significant effects of resistance exercise interventions on fatigue improvement in patients with cancer.

Conclusions

Resistance exercise, resistance exercise combined with aerobic exercise, and resistance exercise combined with other exercises all have a positive effect on improving fitness and QOL in patients with cancer. Resistance exercise has an advantage in improving muscle strength, while combined resistance exercise has an advantage in improving QOL; however, there are no consistent findings in improving fatigue, although low-intensity resistance exercise is effective.

Feasibility and preliminary effects of the Fit2ThriveMB pilot physical activity promotion intervention on physical activity and patient reported outcomes in individuals with metastatic breast cancer

PURPOSE

Physical activity research among patients with metastatic breast cancer (MBC) is limited. This study examined the feasibility and potential benefits of Fit2ThriveMB, a tailored mHealth intervention.

METHODS

Insufficiently active individuals with MBC (n = 49) were randomized 1:1 to Fit2ThriveMB (Fit2ThriveMB app, Fitbit, and weekly coaching calls) or Healthy Lifestyle attention control (Cancer.Net app and weekly calls) for 12 weeks. Fit2ThriveMB aimed to increase daily steps via an algorithm tailored to daily symptom rating and step goal attainment. The primary outcome was feasibility defined as ≥ 80% completion rate. Secondary feasibility metrics included meeting daily step goal and wearing the Fitbit ≥ 70% of study days, fidelity, adherence to intervention features and safety. Secondary outcomes included physical activity, sedentary time, patient reported outcomes (PROs), health-related quality of life (QOL) and social cognitive theory constructs. A subsample (n = 25) completed functional performance tests via video conferencing.

RESULTS

The completion rate was 98% (n = 1 died). No related adverse events were reported. Fit2ThriveMB participants (n = 24) wore the Fitbit 92.7%, met their step goal 53.1%, set a step goal 84.6% and used the app 94.1% of 84 study days. Intent-to-treat analyses indicated trends toward improvements in activity, QOL, and some PROs, social cognitive theory constructs, and functional performance tests favoring the Fit2ThriveMB group. Significant effects favoring Fit2ThriveMB were observed for self-efficacy and goal-setting. However, some PROs and functional performance improvements favored the control group (p-values > 0.05).

CONCLUSIONS

Fit2ThriveMB is feasible and safe for patients with MBC and warrants further evaluation in randomized controlled trials with larger sample sizes. Registration Clinicaltrials.gov NCT04129346, https://clinicaltrials.gov/ct2/show/NCT04129346.

Exercise and recovery after surgery in patients with breast cancer: An analysis of the literature

This review explores the impact of exercise on post-surgical recovery in breast cancer patients. Breast cancer, the most prevalent cancer globally, necessitates treatments beyond conventional modalities such as surgery, chemotherapy, radiotherapy, and immunotherapy. While exercise as an adjuvant therapeutic tool is not novel, it is generally accepted for improving cancer outcomes. Yet, it is not included in current treatment guidelines. This study reviews literature using the FACT-B (Functional Assessment of Cancer Therapy - Breast) tool to evaluate quality of life in breast cancer patients undergoing exercise interventions post-surgery. Despite mixed results, with some studies showing significant improvements and others indicating no notable benefits, the general consensus suggests potential advantages of integrating structured exercise programs into recovery protocols. Standardizing the use of quality of life measures like FACT-B could enhance future research and clinical practices, leading to more effective patient care strategies.

The Effect of Dragon Boating on the Quality of Life for Breast Cancer Survivors: A Systematic Review

Physical activity improves breast cancer-related symptoms in women and decreases cancer-related mortality. The main objective of this systematic review is to synthesize and analyze the evidence of the effect of dragon boating on the quality of life of female breast cancer survivors. A systematic review based on the PRISMA method was conducted using four databases (Web of Science, Scopus, Cochrane and Pubmed). The search phrase used was "Breast Cancer" AND "Dragon Boat" AND "Quality of Life". The search was conducted in June 2024. The PEDro method was used to ensure the quality of the publications. A total of 77 articles published until 2024 were selected, of which 10 met the inclusion criteria of assessing the application of dragon boating and that used a validated instrument to assess quality of life. There is no homogeneity in terms of the instrument used to measure QOL. The SF-36 was the most commonly used, followed by the FACT-B and the EORTC QLQ-C30. Five out of ten articles compared the improvement in quality of life between dragon boating and other physical activities, while 6 out of 10 analyzed the pre-post effect of dragon boat use. Dragon boating is a physical activity alternative that improves the quality of life of breast cancer survivors and reduces the symptomatology caused by the disease and its treatments. As dragon boat programs are applied over a longer period of time, the improvements in quality of life are greater. When compared with other types of physical activity, dragon boating does not show significant differences that position it as a better option for this population.

Adapting an Efficacious Peer-Delivered Physical Activity Program for Survivors of Breast Cancer for Web Platform Delivery: Protocol for a 2-Phase Study

BACKGROUND

Interventions promoting physical activity (PA) among survivors of cancer improve their functioning, reduce fatigue, and offer other benefits in cancer recovery and risk reduction for future cancer. There is a need for interventions that can be implemented on a wider scale than that is possible in research settings. We have previously demonstrated that a 3-month peer-delivered PA program (Moving Forward Together [MFT]) significantly increased the moderate to vigorous PA (MVPA) of survivors of breast cancer.

OBJECTIVE

Our goal is to scale up the MFT program by adapting an existing peer mentoring web platform, Mentor1to1. InquistHealth's web platform (Mentor1to1) has demonstrated efficacy in peer mentoring for chronic disease management. We will partner with InquisitHealth to adapt their web platform for MFT. The adaptation will allow for automating key resource-intensive components such as matching survivors with a coach via the web-based peer mentoring platform and collecting key indexes to prepare for large-scale implementation. The aim is to streamline intervention delivery, assure fidelity, and improve survivor outcomes.

METHODS

In phase 1 of this 2-phase study, we will interview 4 peer mentors or coaches with experience in delivering MFT and use their feedback to create Mentor1to1 web platform adapted for MFT (webMFT). Next, another 4 coaches will participate in rapid, iterative user-centered testing of webMFT. In phase 2, we will conduct a randomized controlled trial by recruiting and training 10 to 12 coaches from cancer organizations to deliver webMFT to 56 survivors of breast cancer, who will be assigned to receive either webMFT or MVPA tracking (control) for 3 months. We will assess effectiveness with survivors' accelerometer-measured MVPA and self-reported psychosocial well-being at baseline and 3 months. We will assess implementation outcomes, including acceptability, feasibility, and program costs from the perspective of survivors, coaches, and collaborating organizations, as guided by the expanded Reach, Effectiveness, Adoption, Implementation, Maintenance (RE-AIM) framework.

RESULTS

As of September 2023, phase 1 of the study was completed, and 61 survivors were enrolled in phase 2. Using newer technologies for enhanced intervention delivery, program management, and automated data collection has the exciting promise of facilitating effective implementation by organizations with limited resources. Adapting evidence-based MFT to a customized web platform and collecting data at multiple levels (coaches, survivors, and organizations) along with costs will provide a strong foundation for a robust multisite implementation trial to increase MVPA and its benefits among many more survivors of breast cancer.

CONCLUSIONS

The quantitative and qualitative data collected from survivors of cancer, coaches, and organizations will be analyzed to inform a future larger-scale trial of peer mentoring for PA delivered by cancer care organizations to survivors.

Combined Aerobic and Resistance Training Improves Body Composition, Alters Cardiometabolic Risk, and Ameliorates Cancer-Related Indicators in Breast Cancer Patients and Survivors with Overweight/Obesity: A Systematic Review and Meta-Analysis of Randomized Controlled Trials

Breast cancer survivors with obesity are at a high risk of cancer recurrence, comorbidity, and mortality. This review aims to systematically evaluate the effects of combined aerobic and resistance training (CART) on body composition, lipid homeostasis, inflammation, adipokines, cancer-related fatigue, sleep, and quality of life in breast cancer patients and survivors with overweight/obesity. An electronic search was conducted in PubMed, Web of Science, Scopus, Science Direct, Cochrane, and Google Scholar databases from inception up to January 8, 2024. Randomized controlled trials (RCTs) meeting the inclusion criteria were selected for the analysis. The Cochrane risk of bias tool was used to assess eligible studies, and the GRADE method to evaluate the quality of evidence. A random-effects model was used, and data were analyzed using mean (MD) and standardized mean differences (SMD) for continuous variables with 95% confidence intervals (CI). We assessed the data for risk of bias, heterogeneity, sensitivity, reporting bias, and quality of evidence. A total of 17 randomized controlled trials were included in the systematic review involving 1,148 female patients and survivors (mean age: 54.0 ± 3.4 years). The primary outcomes showed significant improvements in body mass index (SMD -0.57 kg/m2, p = 0.04), body fat (SMD -0.50%, p = 0.02), fat mass (SMD -0.63 kg, p = 0.04), hip circumference (MD -3.14 cm, p = 0.02), and fat-free mass (SMD 1.03 kg, p < 0.001). The secondary outcomes indicated significant increases in high-density lipoprotein cholesterol (MD -0.05 mmol/L, p = 0.008), natural killer cells (SMD 0.42%, p = 0.04), reductions in triglycerides (MD -81.90 mg/dL, p < 0.01), total cholesterol (SMD -0.95 mmol/L, p < 0.01), tumor necrosis factor α (SMD -0.89 pg/mL, p = 0.03), and leptin (SMD -0.63 ng/mL, p = 0.03). Also, beneficial alterations were found in cancer-related fatigue (SMD -0.98, p = 0.03), sleep (SMD -1.17, p < 0.001), and quality of life (SMD 2.94, p = 0.02) scores. There was very low to low confidence in the estimated effect of most of the outcomes. The present findings reveal that CART could be considered an adjunct therapy in supporting the conventional clinical approach observed following exercise. However, further high-quality research is needed to evaluate whether CART would be a valuable intervention to lower aggressive pharmacologic use in breast cancer patients with overweight/obesity.

Opportunities and Challenges for Augmented Reality in Family Caregiving: Qualitative Video Elicitation Study

BACKGROUND

Although family caregivers play a critical role in care delivery, research has shown that they face significant physical, emotional, and informational challenges. One promising avenue to address some of caregivers' unmet needs is via the design of digital technologies that support caregivers' complex portfolio of responsibilities. Augmented reality (AR) applications, specifically, offer new affordances to aid caregivers as they perform care tasks in the home.

OBJECTIVE

This study explored how AR might assist family caregivers with the delivery of home-based cancer care. The specific objectives were to shed light on challenges caregivers face where AR might help, investigate opportunities for AR to support caregivers, and understand the risks of AR exacerbating caregiver burdens.

METHODS

We conducted a qualitative video elicitation study with clinicians and caregivers. We created 3 video elicitations that offer ways in which AR might support caregivers as they perform often high-stakes, unfamiliar, and anxiety-inducing tasks in postsurgical cancer care: wound care, drain care, and rehabilitative exercise. The elicitations show functional AR applications built using Unity Technologies software and Microsoft Hololens2. Using elicitations enabled us to avoid rediscovering known usability issues with current AR technologies, allowing us to focus on high-level, substantive feedback on potential future roles for AR in caregiving. Moreover, it enabled nonintrusive exploration of the inherently sensitive in-home cancer care context.

RESULTS

We recruited 22 participants for our study: 15 clinicians (eg, oncologists and nurses) and 7 family caregivers. Our findings shed light on clinicians' and caregivers' perceptions of current information and communication challenges caregivers face as they perform important physical care tasks as part of cancer treatment plans. Most significant was the need to provide better and ongoing support for execution of caregiving tasks in situ, when and where the tasks need to be performed. Such support needs to be tailored to the specific needs of the patient, to the stress-impaired capacities of the caregiver, and to the time-constrained communication availability of clinicians. We uncover opportunities for AR technologies to potentially increase caregiver confidence and reduce anxiety by supporting the capture and review of images and videos and by improving communication with clinicians. However, our findings also suggest ways in which, if not deployed carefully, AR technologies might exacerbate caregivers' already significant burdens.

CONCLUSIONS

These findings can inform both the design of future AR devices, software, and applications and the design of caregiver support interventions based on already available technology and processes. Our study suggests that AR technologies and the affordances they provide (eg, tailored support, enhanced monitoring and task accuracy, and improved communications) should be considered as a part of an integrated care journey involving multiple stakeholders, changing information needs, and different communication channels that blend in-person and internet-based synchronous and asynchronous care, illness, and recovery.

Outcomes for breast cancer survivors with metastatic disease in a physical activity program for medically underserved cancer survivors

PURPOSE

This study examined the effectiveness and feasibility of the Active Living After Cancer (ALAC) program for metastatic breast cancer (MBC) survivors.

METHODS

ALAC is a 12-session community-based program to help cancer survivors improve their physical functioning and quality of life through increased physical activity. ALAC participants with MBC (stage IV) were compared to survivors with early-stage breast cancer (stages I and II). The International Physical Activity Questionnaire, Godin Leisure-Time Physical Activity, 30-second sit-to-stand test, and PROMIS Global Health were administered at baseline and follow-up. Program satisfaction and retention were assessed at week 12. Repeated-measures mixed models were used to compare changes in outcomes between survivors with early-stage breast cancer and MBC.

RESULTS

A total of 585 women (59.3 y ± 10.6), most of whom were Hispanic (54%) or non-Hispanic Black (22%), were included (early stage, n = 538; MBC, n = 47). After the ALAC program, a significant increase in physical activity (P < 0.001), improved physical and mental health T-scores (P < 0.001), and more sit-to-stand repetitions (P < 0.001) were observed for both survivors with early-stage breast cancer and MBC. Women with MBC showed significantly lower physical health (P = 0.037) and physical function (P = 0.010) compared to early-stage at baseline.

CONCLUSIONS

The ALAC program increased physical activity and improved health-related quality of life and physical function among breast cancer survivors with both early-stage and metastatic disease.

IMPLICATIONS FOR CANCER SURVIVORS

This study emphasizes the importance of incorporating physical activity interventions like the ALAC program into the comprehensive care of cancer survivors, including those with metastatic disease.

Social Representativeness and Intervention Adherence-A Systematic Review of Clinical Physical Activity Trials in Breast Cancer Patients

Objectives

Representativeness in physical activity randomised controlled trials (RCT) in breast cancer patients is essential to analyses of feasibility and validity considering privileged- social groups. A step-by-step exclusion of less privileged groups through the trial process could reinforce health inequality. This study aimed at examining representativeness in breast cancer (BC) physical activity trials, investigate associations between socio-economic status (SES) and intervention adherence, and explore associations between representativeness and the relationship between SES and intervention adherence.

Methods

Systematic, computerised searches were performed in PubMed, CINAHL, AMED, EMBASE and PsycINFO. Additional citation-based searches retrieved 37 articles. Distributions of education level, ethnicity, and marital status in study samples were compared to national populations data to estimate representativeness in less privileged groups.

Results

A preponderance of studies favoured educated, married and white patients. Only six studies reported SES-adherence associations, hampering conclusions on this relationship and possible associations between representativeness and an SES-adherence relationship.

Conclusion

Less educated, unmarried and non-white individuals may be underrepresented in BC physical activity RCTs, while SES-adherence associations in such trials are inconclusive. Unintentional social misrepresentations may indicate that disguised inequity warrants revived attention.

Role of Gut Microbe Composition in Psychosocial Symptom Response to Exercise Training in Breast Cancer Survivors (ROME) study: protocol for a randomised controlled trial

INTRODUCTION

Breast cancer survivors have an increased risk for chronic fatigue and altered gut microbiota composition, both with negative health and quality of life affects. Exercise modestly improves fatigue and is linked to gut microbial diversity and production of beneficial metabolites. Studies suggest that gut microbiota composition is a potential mechanism underlying fatigue response to exercise. Randomised controlled trials testing the effects of exercise on the gut microbiome are limited and there is a scarcity of findings specific to breast cancer survivors. The objective of this study is to determine if fitness-related modifications to gut microbiota occur and, if so, mediate the effects of aerobic exercise on fatigue response.

METHODS AND ANALYSIS

The research is a randomised controlled trial among breast cancer survivors aged 18-74 with fatigue. The primary aim is to determine the effects of aerobic exercise training compared with an attention control on gut microbiota composition. The secondary study aims are to test if exercise training (1) affects the gut microbiota composition directly and/or indirectly through inflammation (serum cytokines), autonomic nervous system (heart rate variability) or hypothalamic-pituitary-adrenal axis mediators (hair cortisol assays), and (2) effects on fatigue are direct and/or indirect through changes in the gut microbiota composition. All participants receive a standardised controlled diet. Assessments occur at baseline, 5 weeks, 10 weeks and 15 weeks (5 weeks post intervention completion). Faecal samples collect the gut microbiome and 16S gene sequencing will identify the microbiome. Fatigue is measured by a 13-item multidimensional fatigue scale.

ETHICS AND DISSEMINATION

The University of Alabama at Birmingham Institutional Review Board (IRB) approved this study on 15 May 2019, UAB IRB#30000320. A Data and Safety Monitoring Board convenes annually or more often if indicated. Findings will be disseminated in peer-reviewed journals and conference presentations.

Feasibility and preliminary efficacy of a physiotherapy-led remotely delivered physical activity intervention in cancer survivors using wearable technology. The IMPETUS trial

BACKGROUND

Physical activity levels are low in cancer survivors. Remotely delivered programs which harness wearable technology may potentially be beneficial.

OBJECTIVE

To evaluate the feasibility and preliminary efficacy of a remotely delivered, physical activity intervention which harnessed wearable technology.

METHODS

This single arm pre-post longitudinal study included cancer survivors who had completed treatment in the preceding 3 years. Participants were supplied with a Fitbit One® or Flex® for 12 weeks. Physical activity goals were discussed during support phone calls. Outcome measures, assessed at baseline (T1), 12 weeks (T2), and 24 weeks (T3), included feasibility (recruitment, adherence, safety, acceptability) and efficacy [physical activity (Godin leisure time Index, ActiGraph GT3X+), quality of life (functional assessment of cancer therapy - general, short form 36 physical functioning component), functional capacity (six-minute walk test)].

RESULTS

Forty-five participants completed T1 assessments (10 males, 35 females). Thirty-nine (86.6%) of those underwent assessment at T2 and 31 (68.8%) at T3. The intervention was perceived positively with no adverse effects. There were increases in functional capacity (six-minute walk test, p = .002) between T1-T3, an increase in quality of life [short form 36 physical functioning measure (p = .0035), functional assessment of cancer total score (p = .02)] and self-report physical activity levels (p = .000123) between T1-T2, although effect sizes were generally low (d = 0.180 to d = 0.418). Objectively measured physical activity did not change.

CONCLUSION

A physical activity intervention including wearable technology was safe, feasible, and well received by cancer survivors. An intervention based on this proof of concept should be followed up in further studies.

Sex differences of the association between handgrip strength and health-related quality of life among patients with cancer

The purpose of this study is to investigate the association between handgrip strength (HGS) and health-related quality of life (HRQoL), demonstrating HGS as an effective indicator for evaluating HRQoL of patients with cancer. Analyzing 1657 Korean adult cancer patients (644 males, 1013 females) aged ≥ 20 years from the Korea National Health and Nutrition Examination Survey (2014-2019), HGS was standardized based on body mass index and categorized by sex. HRQoL was assessed using the Euro Quality of Life-5-Dimension 3-Level version (EQ-5D-3L) Index. Lower relative HGS was associated with decreased HRQoL in female patients, while no significant association was found in male patients. The lowest quartile of relative HGS exhibited a 2.5-fold decrease in HRQoL compared to the highest quartile (OR 2.50, 95% CI 1.59-3.95, p < 0.001). Both male and female patients with cancer were affected by age, subjective health perception, and stress recognition regarding HRQoL. This study suggests that HGS may be associated with the HRQoL of female patients with cancer, emphasizing that the HGS measurement can be effectively utilized as a pivotal tool for evaluating HRQoL in female patients with cancer.

Examining sociodemographic and health-related characteristics as moderators of an mHealth intervention on physical activity outcomes in young adult cancer survivors

PURPOSE

This study explored whether sociodemographic and health-related characteristics moderated mHealth PA intervention effects on total and moderate-to-vigorous physical activity (MVPA) at 6 months, relative to a self-help condition among young adult cancer survivors (YACS).

METHODS

We conducted exploratory secondary analyses of data from a randomized controlled trial among 280 YACS. All participants received digital tools; intervention participants also received lessons, adaptive goals, tailored feedback, text messages, and Facebook prompts. Potential moderators were assessed in baseline questionnaires. PA was measured at baseline and 6 months with accelerometers. Linear model repeated measures analyses examined within- and between-group PA changes stratified by levels of potential moderator variables.

RESULTS

Over 6 months, the intervention produced MVPA increases that were ≥ 30 min/week compared with the self-help among participants who were males (28.1 vs. -7.7, p = .0243), identified with racial/ethnic minority groups (35.2 vs. -8.0, p = .0006), had baseline BMI of 25-30 (25.4 vs. -7.2, p = .0034), or stage III/IV cancer diagnosis (26.0 vs. -6.8, p = .0041). Intervention participants who were ages 26-35, college graduates, married/living with a partner, had a solid tumor, or no baseline comorbidities had modest MVPA increases over 6 months compared to the self-help (ps = .0163-.0492). Baseline characteristics did not moderate intervention effects on total PA.

CONCLUSIONS

The mHealth intervention was more effective than a self-help group at improving MVPA among subgroups of YACS defined by characteristics (sex, race, BMI, cancer stage) that may be useful for tailoring PA interventions.

IMPLICATIONS FOR CANCER SURVIVORS

These potential moderators can guide future optimization of PA interventions for YACS.

Exercise oncology clinical trials during treatments: a commentary to address the safety concerns of human subjects regulatory reviewers and committees

Exercise oncology clinical trials contribute to the advancement of our scientific knowledge and to the safety and care of patients diagnosed with cancer. Nevertheless, regulatory reviewers and committees may not be familiar with the well-documented long-term health benefits and safety of the regular practice of physical activity. Moreover, they may not see how the benefits outweigh the risks in the context where patients diagnosed with cancer are typically seen as vulnerable. Therefore, we would like to provide a purpose-built overview of exercise oncology clinical trials for members involved in institutional review committees, including the Scientific Review Committee (SRC), the Institutional Review Board (IRB), and the Data Safety Monitoring Committee (DSMC) to facilitate a greater understanding of the safety and benefits of physical activity during cancer treatments. Communication is key to improve the success of exercise oncology clinical trials, which are vital for patients diagnosed with cancer.

Barriers and facilitators to physical activity participation for child, adolescent, and young adult cancer survivors: a systematic review

PURPOSE

The aim of this systematic review is to explore and describe the barriers and facilitators to physical activity (PA) participation for child, adolescent, and young adult cancer survivors.

METHODS

MEDLINE, Embase, AMED, CINAHL, Cochrane, and Web of Science were searched for manuscripts published between January 2000 and February 2021. To be included in this review, studies had to report qualitative or quantitative data on barriers and facilitators to PA participation in child (4 to < 10 years), adolescent (10 to 19 years), and young adult (> 19 to < 40 years) cancer survivors. Six independent reviewers assessed methodological quality using the Mixed Methods Appraisal Tool (MMAT-version 18) in duplicate.

RESULTS

Fifteen studies were included in this systematic review. Fatigue and psychological factors were the most prevalent barriers shared between children, adolescents, and young adults. Support from others was a shared facilitator between age groups.

CONCLUSION

Psychological barriers and social support are important to address in younger cancer survivors. Clinicians can use these findings to create exercise interventions to facilitate and overcome barriers to PA participation.

IMPLICATIONS FOR CANCER SURVIVORS

While PA is beneficial for cancer survivors of all ages, different barriers and facilitators to PA participation exist depending on a survivors age and life stage. Survivors should discuss PA with their healthcare team at all timepoints in the cancer treatment trajectory in order to gain the associated benefits during and after treatment.

Tripartite prehabilitation of patients with acute myeloid leukaemia and high-risk myelodysplastic syndromes during intensive chemotherapy before allogeneic haematopoietic stem cell transplantation (COHABILIT): protocol for an innovating prospective multicentre study

OBJECTIVES

Acute myeloid leukaemia (AML) and high-risk myelodysplastic syndromes (MDS) are often treated with intensive chemotherapy followed by allogeneic haematopoietic stem cell transplantation (allo-HSCT). The pretransplant treatment results in a general deterioration of the patient's health and quality of life. Furthermore, allo-HSCT can be responsible for significant toxicity with risks of graft-versus-host disease (GvHD). Developing strategies to prevent physical deconditioning, undernutrition and psychological distress could help maintain a satisfactory general state of health before transplantation and thus limit these deleterious effects. This protocol evaluates the feasibility and adherence to a personalised prehabilitation programme, which can be modulated and assisted by connected objects, provided from the diagnosis to the allo-HSCT.

METHODS AND ANALYSIS

This multicentre interventional study will include 50 patients treated for AML or high-risk MDS with intensive chemotherapy and eligible for allo-HSCT. The intervention consists of a coached, supervised or self-directed physical activity programme, organised during the hospitalisation phases and periods at home. At the same time, patients will receive a weekly dietary follow-up. The whole intervention is controlled and modulated through the use of a dedicated application and connected objects allowing adaptation and individualisation. The rate of participation in the prescribed physical activity sessions will assess the feasibility of this study. In addition, the evolution of physical capacities (Short Physical Performance Battery, grip and quadriceps strengths), psychosocial parameters (Functional Assessment of Cancer Therapy - Leukaemia, Functional Assessment of Cancer Therapy - Fatigue, subjective well-being, Hospital Anxiety and Depression Scale, self-efficacy, Coach-Athlete Relationship Questionnaire, interviews) and clinical status (weight, lean body mass, survival rate, number of infections, days of hospitalisation, GvHD) will be evaluated.

ETHICS AND DISSEMINATION

The study procedures have been approved by the National Ethics Committee (21.00223.000003). Consent is given in person by each participant. The information collected on the participants contains only a non-identifiable study identifier. The results of this protocol will be published in a scientific paper and communicated to the medical staff of the medical centre.

Psychosocial correlates of physical activity in cancer survivors: a systematic review and meta-analysis

BACKGROUND

Physical activity (PA) is a non-pharmacological approach to optimize health benefits in cancer survivors and is recommended as part of care. However, most cancer survivors fail to meet PA recommendations. The current systematic review and meta-analysis aimed to identify psychosocial correlates of free-living PA in cancer survivors.

METHODS

Three electronic databases were searched (PubMed, PsycINFO, and SportDiscus). Meta-analyses were conducted for psychosocial correlates tested ≥ 3 times.

RESULTS

Sixty-four articles were included. Eighty-eight different free-living PA correlates were identified. Meta-analyses (n = 32 studies) tested 23 PA correlates, of which 16 were significant (p < 0.05). Larger effect sizes (0.30 < ES > 0.45) were found for exercise self-efficacy, perceived behavioral control, intention, lower perceived barriers for exercise, enjoyment, perceived PA benefits, and attitudes. Small-to-moderate effects (0.18 < ES < 0.22) were found for subjective norms, physical functioning, quality of life, depression, and mental health. These findings were generally in line with narrative results.

CONCLUSIONS

This systematic review highlights important psychosocial correlates of free-living PA that can be targeted in future PA promotion interventions for cancer survivors. Constructs mainly from SCT and TPB were the most studied and appear to be associated with free-living PA in this population. However, we cannot currently assert which frameworks might be more effective. Further studies of better methodological quality, per correlate and theory, exploring longer-term associations and across different types of cancer, are needed.

IMPLICATIONS FOR CANCER SURVIVORS

Having higher exercise self-efficacy, perceived behavioral control, intention, enjoyment and perceived PA benefits, more positive attitudes towards PA, and lower perceived barriers for exercise, can help increase PA in cancer survivors.

Impact of exercise interventions on quality of life and depression in lung cancer patients: A systematic review and meta-analysis

INTRODUCTION

Lung cancer is a leading cause of cancer-related mortality worldwide. Depression is also a common concern for lung cancer patients and is of concern because it negatively impacts overall well-being. This study summarizes the existing literature on the impact of exercise interventions on quality of life and depression in patients diagnosed with lung cancer.

METHODS

A systematic search of electronic databases was performed to identify relevant randomized controlled trials (RCTs) investigating the effects of exercise interventions on depression and quality of life in patients with lung cancer. Two evaluators collected information from the chosen studies utilizing a standardized data extraction form. The quality of the studies was evaluated using the Cochrane risk of bias tool.

RESULTS

Nine RCTs were included in the meta-analysis, with 798 participants. The pooled standardized mean difference (SMD) for the effect of exercise interventions on depression was -0.60, representing a statistically significant reduction in depression levels following exercise interventions (p < 0.001). The pooled SMD for the effect of exercise interventions on quality of life was 0.61, indicating a statistically significant association between quality of life and exercise interventions (p < 0.001).

CONCLUSION

There is evidence that exercise may benefit the mental health of individuals with lung cancer, including improvements in depression symptoms and quality of life, based on the intervention studies reviewed here. Given the heterogeneity in findings, however, additional randomized controlled trials are needed to augment the existing findings. Nevertheless, there appears to be sufficient evidence for now to encourage primary care physicians to recommend exercise for patients with lung cancer, while offering guidelines on how to gradually and safely increase physical activity depending on the patient's health status.

App-Based Lifestyle Intervention (PINK! Coach) in Breast Cancer Patients-A Real-World-Data Analysis

INTRODUCTION

Overweight and a lack of physical activity not only increase the risk of recurrence in breast cancer patients but also negatively impact overall and long-term survival, as well as quality of life. The results presented here are the first real-world data from the DiGA PINK! Coach examining the physical activity and BMI of app users. Based on the literature, an approximate weight gain of 10% over 6 months and a decrease in physical activity can be expected. The purpose of this study is to retrospectively investigate the effects of the PINK! Coach in a real-world setting on patients' BMI and physical activity level during acute therapies. such as chemotherapy (CHT) and antihormone therapy (AHT).

MATERIAL AND METHODS

The PINK! Coach app accompanies breast cancer patients during and after acute therapy to bring about a sustainable lifestyle change. The patients are encouraged to establish a healthy diet, become physically active, and make informed decisions. In this study, real-world data from the app were analyzed over 6 months from baseline to T1 (after 12 weeks) and T2 (after 24 weeks). The patients were under acute therapy or in follow-up care receiving either CHT or AHT.

RESULTS

The analyzed data indicate that all patients were able to maintain a consistent BMI over 6 months independent of pre-defined subgroups such as AHT, CHT, or BMI subgroups. In the subgroup of patients undergoing AHT, overweight patients were even able to significantly reduce their BMI by 1-score-point over 6 months (p < 0.01). The subgroup of patients undergoing CHT also showed an significant overall reduction in BMI (p = 0.01). All patients were also able to significantly increase their daily step count as well as their physical activity minutes per day. After the first 12 weeks, 41.4% of patients experienced weight gain, 33.4% were able to maintain their weight, and 24.2% reduced their weight.

CONCLUSION

The presented data provides intriguing insights into the users of the PINK! Coach app and the impact of this usage in regards to BMI and physical activity. At the current time, there are only a few effective concepts for encouraging all breast cancer patients to engage in moderate physical activity and reduce body weight. Often, these concepts apply to selected patient groups. The data presented here include all age groups, tumor stages, and therapies, providing an initial insight into a comprehensive approach. Data over an even longer period would be one way to better contextualize the results in current research.

Lifestyle factors on the long-term survival of gastric cancer patients after radical resection: A cohort study

Background

This retrospective cohort study aimed to evaluate the effect of lifestyle factors (e.g., smoking, drinking, physical exercise, and sleep duration) on the long-term survival of gastric cancer (GC) patients after radical resection.

Materials and Methods

GC patients after radical resection were enrolled from January 2016 to December 2017. Their baseline clinical data, lifestyle factors, and prognosis were collected. The primary endpoint was all-cause death. The relationship between the variables and survival was examined using the Cox proportional hazards model.

Results

A total of 309 patients were enrolled and 296 patients were followed up for a median of 54.0 months, with 130 confirmed deaths. Older age (>60 years) (hazard ratio [HR]: 1.307, 95% confidence interval [CI]: 1.056-2.161, P = 0.006), advanced tumor, node, and metastasis stage (P < 0.05), poorly pathological differentiation (HR: 1.765, 95% CI: 1.080-2.884, P = 0.023), history of smoking (P < 0.001), never physical exercise (HR: 2.057, 95% CI: 1.170-3.617, P = 0.012), long sleep duration (≥8 h) (HR: 4.160, 95% CI: 1.501-11.533, P = 0.006), and short sleep duration (<6 h) (HR: 3.417, 95% CI: 1.312-8.900, P = 0.012) were independent indicators of a poor overall survival in GC patients after radical resection.

Conclusion

Smoking cessation, proper sleep duration, and regular physical exercise habits can improve the long-term survival of GC patients after radical resection.

Meaning of nutrition for cancer survivors: a photovoice study

Background

Little is known about how cancer survivors perceive nutrition through the cancer experience and how those perceptions may influence their diet.

Aims

This study aimed to capture the meaning of nutrition for cancer survivors who are post-cancer treatment using a participatory photography method known as photovoice.

Methods

Wang and Burris's photovoice procedure was followed. Recruitment took place via email through existing links with participants from a previous quantitative study. The participants were tasked with taking photographs to represent the meaning of nutrition for them post-treatment. Group workshops and semistructured interviews were conducted to facilitate reflection, dialogue and analysis. Data analysis followed Braun and Clarke's six-phase thematic analysis.

Results

One man and seven women (n=8) across the Island of Ireland were recruited. Participants identified six themes (illustrated with photographs): (1) Fresh is Best, (2) Be kind to yourself, (3) Building Blocks. Be Informed., (4) Post-Treatment Healing Changes, (5) Chemo Rituals and (6) Food for the Soul-Healthy Mind. Healthy Body.

Conclusions

Participants displayed a holistic approach to a healthy lifestyle for recovery post-treatment and maintaining health. While diverse, participants made post-treatment nutritional changes by introducing and eliminating certain foods or food groups. All agreed that being informed and building nutrition knowledge are essential. It is important to clarify the implications cancer has had on diet and health when providing nutrition guidance to ensure that it is appropriate and specific.

Pre-post feasibility trial of a telephone-delivered exercise intervention for patients during chemotherapy for recurrent ovarian cancer: the ECHO-R trial protocol

INTRODUCTION

The benefits of exercise in reducing treatment-related morbidity and improving quality of life following a primary diagnosis of cancer have been well documented and have led to exercise being recommended by oncology societies for all people with a cancer diagnosis. However, these recommendations are derived from research typically involving cohorts with more common cancers and relatively good prognosis, such as breast and prostate. Evidence from these cancers may not apply to women with recurrent ovarian cancer. Therefore, the primary objective of this trial is to evaluate the feasibility and safety of a home-based, telephone-delivered exercise intervention for women undergoing chemotherapy for recurrent ovarian cancer.

METHODS AND ANALYSIS

The Exercise During Chemotherapy for Recurrent Ovarian Cancer (ECHO-R) trial is a single-arm, phase II, pre/postintervention trial of a 6-month, telephone-delivered exercise intervention (consistent with recommended exercise oncology prescription). The target sample size is 80 women who are currently undergoing (or are scheduled to receive) chemotherapy for recurrent ovarian cancer. Recruitment is through participating hospital sites in Queensland, Australia, or via self-referral. The exercise intervention comprises 12 telephone sessions over a 6-month period delivered by trial-trained exercise professionals and supplemented (where feasible) by five sessions face to face. Exercise prescription is individualised and works towards an overall goal of achieving a weekly target of 150 min of moderate-intensity, mixed-mode exercise. Assessments via self-administered survey and physical fitness and function tests occur at baseline and then at 6 and 9 months postbaseline. Data to inform feasibility and safety are recorded as case notes by the exercise professional during each session.

ETHICS AND DISSEMINATION

Ethics approval for the ECHO-R trial was granted by the Metro North Human Research Ethics Committee (HREC/2020/QRBW/67223) on 6 November 2020. Findings from the trial are planned to be disseminated via peer-reviewed publications and both national and international exercise and oncology conferences.

Impact of a one-year supervised physical activity program on long-term cancer-related fatigue and mediating effects of the gut microbiota in metastatic testicular cancer patients: protocol of the prospective multicentre, randomized controlled phase-III STARTER trial

BACKGROUND

Testicular germ cell tumours (TGCTs) are the most common malignancy in men aged 15-40 years, with increasing incidence worldwide. About 33 ~ 50% of the patients present with metastatic disease at diagnosis. TGCT survivors experience short- and long-term sequelae, including cancer-related fatigue (CRF). Physical activity (PA) has established effects on reducing CRF and other sequelae and improving health-related quality of life (HRQoL). However, its impact on TGCT survivors has so far received little attention. The gut microbiota plays a crucial role in various physiological functions, including cognition and metabolism, and may mediate the effects of PA on CRF and other sequelae, but this has not been investigated in randomized controlled trials.

METHODS

This national, multicentre, phase-III trial will evaluate the impact of a one-year supervised PA program on CRF and other short- and long-term sequelae in metastatic TGCT patients receiving cisplatin-based chemotherapy combined with etoposide+/-bleomycin. It will also investigate potential mediating effects of the gut microbiota and its metabolites involved in the gut-brain axis on the relationship between PA and CRF and other sequelae. A total of 236 men ≥ 18 years of age with metastatic TGCT (seminoma and non-seminoma) will be enrolled before starting first-line chemotherapy in several French hospitals. The primary (CRF) and secondary (cognitive/psychological/metabolic sequelae, HRQoL, etc.) outcomes and gut microbiota and relevant metabolites will be assessed at inclusion, during and at the end of the one-year intervention, and annually until 10 years since inclusion to assess long-term sequelae, more specifically CRF, cardiovascular toxicities, and second primary cancer occurrence in this population.

DISCUSSION

This trial will provide comprehensive and novel insights into the effects of a long-term supervised PA program on CRF and other sequelae in metastatic TGCT patients receiving first-line chemotherapy. It will also contribute to understanding the potential role of the gut microbiota and its metabolites in mediating the effects of PA on these outcomes. The findings of this study will help the development of effective PA interventions to improve the health of TGCT survivors and may have implications for other cancer populations as well.

TRIAL REGISTRATION

The study was registered on ClinicalTrials.gov (NCT05588700) on 20 Oct. 2022.

Timing of exercise therapy when initiating adjuvant chemotherapy for breast cancer: a randomized trial

AIMS

The most appropriate timing of exercise therapy to improve cardiorespiratory fitness (CRF) among patients initiating chemotherapy is not known. The effects of exercise therapy administered during, following, or during and following chemotherapy were examined in patients with breast cancer.

METHODS AND RESULTS

Using a parallel-group randomized trial design, 158 inactive women with breast cancer initiating (neo)adjuvant chemotherapy were allocated to receive (1:1 ratio): usual care or one of three exercise regimens-concurrent (during chemotherapy only), sequential (after chemotherapy only), or concurrent and sequential (continuous) (n = 39/40 per group). Exercise consisted of treadmill walking three sessions/week, 20-50 min at 55%-100% of peak oxygen consumption (VO2peak) for ≈16 (concurrent, sequential) or ≈32 (continuous) consecutive weeks. VO2peak was evaluated at baseline (pre-treatment), immediately post-chemotherapy, and ≈16 weeks after chemotherapy. In intention-to-treat analysis, there was no difference in the primary endpoint of VO2peak change between concurrent exercise and usual care during chemotherapy vs. VO2peak change between sequential exercise and usual care after chemotherapy [overall difference, -0.88 mL O2·kg-1·min-1; 95% confidence interval (CI): -3.36, 1.59, P = 0.48]. In secondary analysis, continuous exercise, approximately equal to twice the length of the other regimens, was well-tolerated and the only strategy associated with significant improvements in VO2peak from baseline to post-intervention (1.74 mL O2·kg-1·min-1, P < 0.001).

CONCLUSION

There was no statistical difference in CRF improvement between concurrent vs. sequential exercise therapy relative to usual care in women with primary breast cancer. The promising tolerability and CRF benefit of ≈32 weeks of continuous exercise therapy warrant further evaluation in larger trials.

Physical activity in people diagnosed with cancer: a rapid review of recommendations and critical appraisal of international guidelines

PURPOSE

There are numerous guidelines that recommend physical activity (PA) in people diagnosed with cancer, but the quality of these guidelines is unknown. The aim of this study was to identify existing PA guidelines for cancer survivors, describe the recommendations, and assess their methodology quality.

METHODS

A rapid review of the literature was conducted in PubMed and EMBASE, supplemented by a search of the grey literature. The methodological quality of the guidelines was assessed using the AGREE II checklist. A descriptive synthesis of the recommendations from guidelines judged to be of good quality has been performed.

RESULTS

A total of nine guidelines published between 2006 and 2019 were included. Of nine guidelines, five achieved a high enough AGREE II score and were judged to be of good quality for use in clinical practice. We found that the recommendations from the five guidelines converged on the prescription of supervised PA (aerobic and resistance exercise) of at least 75 min per week of high intensity or 150 min per week of moderate intensity, spread over two to five sessions per week, equating to a PA dose between 8.70 and 17.5 MET.h/week. The recommendations were applicable to address the most common side effects of cancer and its treatment, namely fatigue, lymphedema, anxiety, depressive symptoms, health-related quality of life (QoL), survival, and physical function. However, no guideline recommends PA to improve other cancer-related outcomes, such as cognitive impairment, falls, sexual function, and peripheral neuropathy frequently experienced by cancer survivors. No guideline also referred to work outcomes (i.e., work ability, return to work, etc.).

CONCLUSION

Most PA guidelines for cancer survivors are of good quality. However, specific PA guidelines are needed for a given cancer site (e.g., location, stage), at a particular phase of the cancer trajectory, and for specific outcomes including return to work (RTW) in order to tailor PA to each cancer survivor.

Long-term efficacy of a computer-tailored physical activity intervention for prostate and colorectal cancer patients and survivors: A randomized controlled trial

BACKGROUND

Physical activity (PA) can improve the physical and psychological health of prostate and colorectal cancer survivors, but PA behavior change maintenance is necessary for long-term health benefits. OncoActive is a print- and web-based intervention in which prostate and colorectal cancer patients and survivors receive automatically generated, personalized feedback aimed at integrating PA into daily life to increase and maintain PA. We evaluated the long-term outcomes of OncoActive by examining the 12-month follow-up differences between OncoActive and a control group, and we explored whether PA was maintained during a 6-month non-intervention follow-up period.

METHODS

Prostate or colorectal cancer patients were randomly assigned to an OncoActive (n = 249) or a usual care waitlist control group (n = 229). OncoActive participants received PA advice and a pedometer. PA outcomes (i.e., ActiGraph and self-report moderate-to-vigorous intensity PA (MVPA) min/week and days with ≥30 min PA) and health-related outcomes (i.e., fatigue, depression, physical functioning) were assessed at baseline, 6 months, and 12 months. Differences between groups and changes over time were assessed with multilevel linear regressions for the primary outcome (ActiGraph MVPA min/week) and all additional outcomes.

RESULTS

At 12 months, OncoActive participants did not perform better than control group participants at ActiGraph MVPA min/week, self-report MVPA min/week, or ActiGraph days with PA. Only self-report days with PA were significantly higher in OncoActive compared to the control group. For health-related outcomes only long-term fatigue was significantly lower in OncoActive. When exploratively examining PA within OncoActive, the previously found PA effects at the end of the intervention (6 months follow-up) were maintained at 12 months. Furthermore, all PA outcomes improved significantly from baseline to 12 months. The control group showed small but non-significant improvements from 6 months to 12 months (and from baseline to 12 months), resulting in a decline of differences between groups.

CONCLUSION

The majority of previously reported significant between-group differences at 6 months follow-up were no longer present at long-term follow-up, possibly because of natural improvement in the control group. At long-term follow-up, fatigue was significantly lower in OncoActive compared to control group participants. Computer-tailored PA advice may give participants an early start toward recovery and potentially contributes to improving long-term health.

Time to embed physical activity within usual care in cancer services: A qualitative study of cancer healthcare professionals' views at a single centre in England

PURPOSE

An increasing number of people affected by cancer (PABC) are living longer lives as treatment continues to advance. There is growing evidence for physical activity (PA) supporting health in this population before, during and after cancer treatment, but PA advice is not part of usual care. This study investigates views of frontline oncology healthcare professionals (HCPs) in one NHS teaching hospital in England to understand the role of PA advice across cancer services.

MATERIALS AND METHODS

This was a qualitative study interviewing HCPs and using thematic analysis.

RESULTS

Four main themes were identified: 1. Awareness of the roles of PA in cancer; 2. Patient-specific factors in rehabilitation; 3. Cancer-specific factors in rehabilitation; 4. Barriers and opportunities to integrating PA within usual care. HCPs' awareness of the role of PA in cancer rehabilitation was low overall and PA was found not to be embedded within rehabilitation. Contrastingly, there was awareness of PA's potential to impact disease and treatment-related outcomes positively. Ideas for PA integration included training for staff and giving PA advice within consultations.

CONCLUSIONS

Low awareness of benefits of PA-based rehabilitation and lack of integration in usual care contrasted with HCPs' interest in this area's potential. Training HCPs to begin the conversation with patients affected by cancer in teachable moments may increase patient access.Implications for rehabilitationIntegrating physical activity education and training for trainees and existing healthcare professionals workforce would help embed physical activity into routine clinical practice.Brief advice intervention training during every consultation, such as providing relevant individualised information and signposting, can be impactful.Physical activity within a broader cancer rehabilitation programme should be integrated as standard for every cancer patient.Individualised plans may include prehabilitation, restorative rehabilitation and palliative rehabilitation.Patient preferences and the patient experience should continue to shape service design.There is a need to ensure physical activity advice is consistent throughout healthcare settings and not fragmented between primary, secondary and tertiary care.

Effect of exercise on body composition among women with ovarian cancer

PURPOSE

Obesity is associated with a higher risk of mortality in women with ovarian cancer. Exercise has improved body composition among cancer survivors, yet no randomized controlled trial has explored the effect of exercise on body composition in women with ovarian cancer. In this analysis, we examined the effect of a six-month aerobic exercise intervention on body composition among ovarian cancer survivors in the Women's Activity and Lifestyle Study in Connecticut (WALC).

METHODS

Women with ovarian cancer (N = 144) were randomized in a 1:1 ratio to 6 months of an aerobic exercise intervention or attention-control, and body composition was measured as a secondary outcome at baseline and 6 months via dual-energy X-ray absorptiometry (DEXA). Women with at least one DEXA scan were included in the analysis (N = 103).

RESULTS

On average, participants were 57.1 (± 8.7) years old and 1.6 (± 0.9) years since diagnosis. Women randomized to exercise maintained weight during the trial (- 0.11 kg, P = 0.82), while women in attention-control gained weight (+ 1.40 kg, P = 0.03); however, the between-group difference did not reach statistical significance (P = 0.09). We found no statistically significant differences by study arm for changes in body fat percentage, bone mineral density, or lean body mass.

CONCLUSIONS

Weight was maintained as a result of a 6-month aerobic exercise intervention among post-treatment ovarian cancer survivors. Future exercise and healthy eating interventions should consider additional measures (e.g., computer tomography scans, D3-creatinine) to more accurately assess changes in body composition.

IMPLICATIONS FOR CANCER SURVIVORS

Moderate-intensity aerobic exercise may help ovarian cancer survivors maintain weight.

Effects of a 12-week supervised resistance training program, combined with home-based physical activity, on physical fitness and quality of life in female breast cancer survivors: the EFICAN randomized controlled trial

PURPOSE

This study assessed the effects of 12-week supervised resistance training combined with home-based physical activity on physical fitness, cancer-related fatigue, depressive symptoms, health-related quality of life (HRQoL), and life satisfaction in female breast cancer survivors.

METHODS

A parallel-group, outcome assessor-blinded, randomized controlled trial included 60 female breast cancer survivors who had completed their core treatments within the previous 10 years. Through computer-generated simple randomization, participants were assigned to resistance training (RTG; two sessions/week for 12 weeks plus instructions to undertake ≥ 10,000 steps/d) or control (CG; ≥ 10,000 steps/d only). Outcomes were evaluated at baseline and week 12. Muscular strength was assessed with electromechanical dynamometry. A standardized full-body muscular strength score was the primary outcome. Secondary outcomes included cardiorespiratory fitness, shoulder mobility, cancer-related fatigue, depressive symptoms, HRQoL, and life satisfaction.

RESULTS

Thirty-two participants were assigned to RTG (29 achieved ≥ 75% attendance) and 28 to CG (all completed the trial). Intention-to-treat analyses revealed that the standardized full-body muscular strength score increased significantly in the RTG compared to the CG (0.718; 95% CI 0.361-1.074, P < 0.001, Cohen's d = 1.04). This increase was consistent for the standardized scores of upper-body (0.727; 95% CI 0.294-1.160, P = 0.001, d = 0.87) and lower-body (0.709; 95% CI 0.324-1.094, P = 0.001, d = 0.96) strength. There was no effect on cardiorespiratory fitness, shoulder flexion, cancer-related fatigue, depressive symptoms, HRQoL, or life satisfaction. The sensitivity analyses confirmed these results.

CONCLUSION

and implication for cancer survivors. In female breast cancer survivors who had completed their core treatments within the past 10 years, adding two weekly sessions of supervised resistance training to a prescription of home-based physical activity for 12 weeks produced a large increase in upper-, lower-, and full-body muscular strength, while other fitness components and patient-reported outcomes did not improve.

Physical fitness and its association with fatigue in patients with low-grade glioma

PURPOSE

To evaluate physical fitness and its association with fatigue in patients with low grade glioma (LGG).

METHODS

Cross-sectional study. Muscle strength was measured with a digital dynamometer, cardiorespiratory fitness (peak oxygen uptake (VO2peak), maximal workload (MWL)) by cardiopulmonary-exercise-testing, and fatigue by using the Multidimensional Fatigue Inventory.

RESULTS

Thirty patients were included, mean age of 44.1 (SD11.2) years, and 67% were men, 31.2 (SD18) months post-diagnosis. Muscle strength (p < 0.01), and cardiorespiratory fitness (VO2peak, MWL) (p < 0.01) were significantly decreased compared to predicted values based on age and gender. Thirty percent of the patients experienced severe physical fatigue, and severe mental fatigue was reported in 57% of the patients. Cardiorespiratory fitness showed weak to moderate (r - 0.46 to r - 0.52) but significant (p < 0.01) correlations with physical fatigue, not with mental and general fatigue. Muscle strength was not associated with fatigue. A lower VO2peak was independently associated with a higher level of physical fatigue, adjusted for Karnofsky Performance Status (R2 0.40).

CONCLUSIONS

Physical fitness (muscle strength, cardiorespiratory fitness) is reduced in patients with LLG, and a lower level of cardiorespiratory fitness (VO2peak) is independently associated with a higher level of experienced physical fatigue. Trials to explore the benefit of exercise programs to improve cardiorespiratory fitness and, consequently, fatigue are warranted.Implications for rehabilitationPhysical fitness (muscle strength and cardiorespiratory fitness) is reduced in patients with low-grade glioma.Patients with low-grade glioma should be screened for fatigue with the multidimensional fatigue inventory, to differentiate between mental and physical fatigue.Patients with low-grade glioma with severe physical fatigue should be screened for reduced physical fitness, especially cardiorespiratory fitness by objective cardiopulmonary-exercise-testing.Rehabilitation exercise programs to improve cardiorespiratory fitness and, consequently, (physical) fatigue could be warranted in patients with low-grade glioma.

Etiology and treatment of cancer-related secondary lymphedema

Lymphedema and specifically cancer-related lymphedema is not the main focus for both patients and physicians dealing with cancer. Its etiology is an unfortunate complication of cancer treatment. Although lymphedema treatments have gained an appreciable consensus, many practitioners have developed and prefer their own specific protocols and this is especially true for conventional (manual) versus surgical treatments. This collection of presentations explores the incidence and genetics of cancer-related lymphedema, early detection and monitoring techniques, both conventional and operative treatment options, and the importance and role of exercise for patients with cancer-related lymphedema. These assembled presentations provide valuable insights into the challenges and opportunities presented by cancer-related lymphedema including the latest research, treatments, and exercises available to improve patient outcomes and quality of life.

Characterization and efficacy of lifestyle behavior change interventions among adult rural cancer survivors: a systematic review

PURPOSE

Little is known about the intersection between age and rurality as characteristics that impact lifestyle behavior change for cancer survivors. This review aims to summarize the current literature on lifestyle behavior change interventions conducted among rural survivors of cancer, with an emphasis on older survivors.

METHODS

A systematic search of five databases identified randomized controlled trials and controlled clinical trials that targeted diet, physical activity, alcohol consumption, or tobacco use change in adult cancer survivors living in rural areas of the world.

RESULTS

Eight studies met the inclusion criteria. Most studies were conducted in either Australia or the USA, included survivors at least 6 weeks post-treatment, and half included only breast cancer survivors, while the other four included a mix of cancer types. All but one had a physical activity component. No articles addressed changes in alcohol or tobacco behavior. Seven (87.5%) had a fully remote or hybrid delivery model. Most of the physical activity interventions showed significant changes in physical activity outcomes, while the dietary interventions showed changes of clinical but not statistical significance.

CONCLUSIONS

Few studies have been conducted to implement and evaluate the effectiveness of lifestyle behavior change interventions among older rural survivors of cancer. Future research should evaluate the acceptability and relevancy of adapted, evidence-based intervention with this population.

IMPLICATIONS FOR CANCER SURVIVORS

Effective diet and physical activity interventions exist, albeit limited in terms of effective lifestyle behavior change intervention tailored to older, rural survivors of cancer, particularly in relation to alcohol and tobacco behaviors.

A Comparison of the Physical Activity and Sedentary Behavior between Autologous and Allogeneic Hematopoietic Stem Cell Transplantation Survivors

Objective The treatment background, as well as the frequency and type of complications, in autologous (auto-) and allogeneic (allo-) hematopoietic stem cell transplantation (HSCT) survivors influence the appearance of moderate to vigorous physical activity (MVPA) or sedentary behavior. We therefore assessed differences in the MVPA and sedentary behavior between auto- and allo-HSCT survivors. Methods This prospective observational study included 13 auto- and 36 allo-HSCT survivors (approximately 4 years after HSCT). The MVPA and sedentary behavior were assessed using a triaxial accelerometer. Results There were no significant between-group differences in the MVPA or sedentary behavior (p=0.768 and 0.739, respectively). In allo-HSCT survivors, the MVPA was negatively correlated with the Hospital Anxiety and Depression Scale score (r=-0.358, p=0.032). A stepwise multiple regression analysis showed that age was a significant predictor of sedentary behavior in allo-HSCT survivors (β=0.400, p=0.016). Conclusion We observed no significant between-group differences in the MVPA or sedentary behavior. Our results suggest that it may be unnecessary to change the rehabilitation program according to the donor type in interventions for promoting MVPA and reducing sedentary behavior in long-term HSCT survivors.

Which Intervention Strategies Promote the Adoption and Maintenance of Physical Activity? Evidence From Behavioral Trials With Cancer Survivors

BACKGROUND/PURPOSE

We address four questions about interventions to promote physical activity in cancer survivors: (a) How often is both the adoption and maintenance of behavior change tested in trials? (b) How often do interventions generate adoption-plus-maintenance of behavior change? (c) Are intervention strategies specifically geared at promoting maintenance of behavior change deployed in trials? and (d) Which intervention strategies distinguish trials that promote both the adoption and maintenance of physical activity from trials that promote adoption-only or generate no behavioral changes?

METHODS

Computerized literature searches identified 206 reports of randomized trials that measured physical activity in the wake of the intervention.

RESULTS

Only 51 reports (24%) measured both behavioral adoption (postintervention) and behavioral maintenance (≥3 months follow-up). The 51 reports included 58 tests of interventions; 22% of tests observed both adoption and maintenance of physical activity, 26% reported adoption-only, and 52% found no change in behavior. Change techniques designed to promote behavioral maintenance were used much less frequently than adoption techniques or adoption and maintenance techniques. Interventions that aimed to improve quality of life, used supervised exercise sessions, were undertaken in community centers, and deployed fewer behavior change techniques were associated with adoption-plus-maintenance of physical activity in cancer survivors.

CONCLUSIONS

The present findings offer new insights into the adoption and maintenance of physical activity and highlight the need to routinely assess these forms of behavior change in future trials. More extensive testing of intervention strategies specifically geared at maintenance of behavior change is warranted.

Understanding In-Person and Online Exercise Oncology Programme Delivery: A Mixed-Methods Approach to Participant Perspectives

Alberta Cancer Exercise (ACE) is an exercise oncology programme that transitioned from in-person to online delivery during COVID-19. The purpose of this work was to understand participants' experiences in both delivery modes. Specifically, survivors' exercise facilitators and barriers, delivery mode preference, and experience with programme elements targeting behaviour change were gathered. A retrospective cohort design using explanatory sequential mixed methods was used. Briefly, 57 participants completed a survey, and 19 subsequent, optional interviews were conducted. Most participants indicated preferring in-person programmes (58%), followed by online (32%), and no preference (10%). There were significantly fewer barriers to (i.e., commute time) (p < 0.01), but also fewer facilitators of (i.e., social support) (p < 0.01), exercising using the online programme. Four themes were generated from the qualitative data surrounding participant experiences in both delivery modes. Key differences in barriers and facilitators highlighted a more convenient experience online relative to a more socially supportive environment in-person. For future work that includes solely online delivery, focusing on building social support and a sense of community will be critical to optimising programme benefits. Beyond the COVID-19 pandemic, results of this research will remain relevant as we aim to increase the reach of online exercise oncology programming to more underserved populations of individuals living with cancer.

Update on the risk assessment of a rehabilitation stay for patients after allogeneic stem cell transplantation

OBJECTIVE

High-dose chemotherapy with allogeneic stem cell transplantation is the only chance of cure for many haemato-oncological patients. After such therapy, the immune system is weakened, and the contact with other people should therefore be limited as much as possible. The question arises whether a rehabilitation stay can be recommended to these patients, which risk factors for complications during the rehabilitation stay can be identified, and whether physicians and patients can be provided with decision-making aids as to when the optimal time is to start rehabilitation.

METHODS

We report about 161 rehabilitation stays of patients after high-dose chemotherapy with allogeneic stem cell transplantation. Premature discontinuation of the rehabilitation was selected as the criterion for a serious complication during the rehabilitation and the underlying reasons were analysed.

RESULTS

The rate of prematurely terminated rehabilitation stays (13.6%) corresponds to our previous result from 2020. The analysis of the reasons for early termination comes to the conclusion that the rehabilitation stay is only considered as a reason for termination in very few cases, if at all. The risk factors identified for premature termination of the rehabilitation stay were male sex, the period (days) between transplantation and the beginning of the rehabilitation stay, haemoglobin value, platelets and presence of immunosuppressing agent. The most significant risk factor is a decreased platelet count at the time rehabilitation begins. The platelet count, the likelihood that it will improve in the further course and the urgency of the rehabilitation stay can be used to help decide when the optimal time for rehabilitation is given.

CONCLUSION

Rehabilitation can be recommended to patients after allogeneic stem cell transplantation. Based on various factors, recommendations can be made for the right time for rehabilitation.

Association between greenspace and cancer: evidence from a systematic review and meta-analysis of multiple large cohort studies

Cancer is a chronic disease that seriously endangers human health, and studies on its association with greenspace have been published. We aimed to systematically review the epidemiological evidence and obtain the best available evidence. PubMed, Web of Science, Embase, and Cochrane Library were used as search databases, the time limit was September 12, 2022, and the cited articles were manually supplemented. Two researchers independently performed literature screening and data extraction. We performed a meta-analysis of data using a normalized difference vegetation index (NDVI) as the greenspace measure, providing hazard ratio (HR) and corresponding 95% CI. After standardization of the data, we used a random effects model for pooling. We also assessed the risk of bias for each study and the quality of each evidence body. We identified 10,108 items and included 14 studies from 11 institutions in eight countries. All studies had a low risk of bias. Quantitative analysis of 13 studies found a beneficial association of greenspace with the mortality of lung cancer (pooled HR [95% CI]=0.965 [0.947, 0.983]) and prostate cancer (HR [95% CI]=0.939 [0.898, 0.980]) based on 0.1-unit NDVI increment and a potential beneficial association with the incidence of prostate, lung, and breast cancer. Greenspace had opposite associations with cancer mortality for urban and rural populations. Indirect comparisons did not find statistically significant differences in the effects of greenspace on different cancer outcomes. The evidence body assessment was considered to be "very low." This review indicated potential beneficial associations between greenspace for lung, prostate, and breast cancer outcomes. However, there was a lack of mediation analysis to explore the underlying mechanism of a causal association. Meanwhile, the interstudy heterogeneity was large. Therefore, future studies should consider more accurate exposure assessment and more comprehensive covariate coverage, while focusing on mediating analysis. PROSPERO: CRD42022361068.

Quality of life considerations and management in patients with myelodysplastic syndrome

INTRODUCTION

This study aimed to identify the factors affecting the quality of life (QOL) and functional status of patients with MDS.

AREAS COVERED

We reviewed the literature published in PUBMED over the past 30 years and searched for keywords such as 'quality of life' and 'myelodysplastic syndromes'. By observing the influence of their symptoms, the possibility of improving patients' QOL was considered by improving these related factors. Concurrently, the effects of related clinical treatments based on the unique disease characteristics of MDS on the patients' QOL were examined, and lifestyle factors were considered in clinical practice, providing an important path to improve the QOL and functional status of patients with MDS.

EXPERT OPINION

This review summarized several areas that can improve the quality of survival of MDS patients and discusses them in depth. Although the clinical benefits may be minimal, we still hope to improve patients' daily life outcomes and enhance their quality of life at minimal cost. Also, we hope more researchers will focus on this area in the future to find more factors that may exist to supplement the limitations of these understanding and thinking, and to provide assistance in clinical work.

A multi-site trial of an electronic health integrated physical activity promotion intervention in breast and endometrial cancers survivors: MyActivity study protocol

Despite the known benefits of moderate-to-vigorous physical activity (MVPA) for breast and endometrial cancer survivors, most are insufficiently active, interventions response is heterogeneous, and MVPA programming integration into cancer care is limited. A stepped care approach, in which the least resource-intensive intervention is delivered first and additional components are added based on individual response, is one strategy to enhance uptake of physical activity programming. However, the most effective intervention augmentation strategies are unknown. In this singly randomized trial of post-treatment, inactive breast and endometrial cancer survivors (n = 323), participants receive a minimal intervention including a Fitbit linked with their clinic's patient portal and, in turn, the electronic health record (EHR) with weekly feedback delivered via the portal. MVPA progress summaries are sent to participants' oncology team via the EHR. MVPA adherence is evaluated at 4, 8, 12, 16 and 20 weeks; non-responders (those meeting ≤80% of the MVPA goal over previous 4 weeks) at each timepoint are randomized once for the remainder of the 24-week intervention to one of two "step-up" conditions: (1) online gym or (2) coaching calls, while responders continue with the minimal Fitbit+EHR intervention. The primary outcome is ActiGraph-measured MVPA at 24 and 48 weeks. Secondary outcomes include symptom burden and functional performance at 24 and 48 weeks. This trial will inform development of an effective, scalable, and tailored intervention for survivors by identifying non-responders and providing them with the intervention augmentations necessary to increase MVPA and improve health outcomes.

Benefits of nature-based walking for breast cancer survivors

INTRODUCTION

Physical activity (PA) promotes significant physical and psychosocial benefits for breast cancer survivors. While evidence exists regarding recommendations for the frequency, duration and intensity of exercise that optimise PA benefits for cancer survivors, the role of the environment in achieving optimal outcomes has yet to be determined. This paper presents a protocol for a clinical trial to evaluate the feasibility of a 3-month nature-based walking programme for breast cancer survivors. Secondary outcomes assessed include the impact of the intervention on fitness, quality of life outcomes, and biomarkers of ageing and inflammation.

METHODS AND ANALYSIS

The trial is a 12-week single-arm pilot study. Twenty female breast cancer survivors will engage in a supervised moderate intensity walking intervention in small groups in a nature reserve for 50 minutes three times per week. Data will be collected at baseline and end of study, and include assessment of inflammatory cytokines and anti-inflammatory myokines (TNF-α, IL-1ß, IL-6, CRP, TGF-ß, IL-10, IL-13), as well as ageing (DNA methylation, ageing genes) biomarkers; surveys (Patient-Reported Outcomes Measurement Information System-29, Functional Assessment of Cancer Therapy-General, Post-Traumatic Growth Inventory); and fitness assessments (6 min Walk Test, Grip-Strength, One Repetition-Maximum Leg Press). Participants will also complete weekly surveys assessing social support and participate in an exit interview. This is an important first step for future research on the influence of exercise environment on cancer survivor PA outcomes.

ETHICS AND DISSEMINATION

This study was approved by the Cedars Sinai Medical Center Institutional Review Board (IIT2020-20). Findings will be disseminated through academic manuscripts, conferences, and community presentations.

Aqua polo: Preliminary feasibility and efficacy study of a programme of adapted, supervised water polo to reduce fatigue and improve women's psychological and social recovery after breast cancer treatment: A mixed-methods design

Physical activity has been shown to have many benefits, including reducing cancer-related fatigue (CRF) and improving psychological and physical recovery from breast cancer. Some authors have shown the benefits of aquatic practice, while others have detailed the benefits of group and supervised practice. We hypothesize that an innovative sports coaching proposal could allow a significant adherence of patients and contribute to their health improvement. The main objective is to study the feasibility of an adapted water polo programme (aqua polo) for women after breast cancer. Secondarily we will analyse the effect of such a practice on patients' recovery and study the relationship between coaches and participants. The use of mixed methods will allow us to question the underlying processes precisely. This is a prospective, non-randomized, monocentric study with a sample of 24 breast cancer patients after treatment. The intervention is a 20 week programme (1 session per week) of aqua polo in a swim club facility, supervised by professional water-polo coaches. The variables measured are patient participation, quality of life (QLQ BR23), CRF (R-PFS) and post-traumatic growth (PTG-I) as well as different variables to observe physical capacity (strength with dynamometer, step-test and arm amplitude). The quality of the coach-patient relationship will be evaluated (CART-Q) to explore its dynamics. Participatory observations and interviews will be carried out to report on the interactions between the coach and the participants during the sessions.

The Streaming Web-Based Exercise at Home Study for Breast and Prostate Cancer Survivors: A Feasibility Study Protocol

BACKGROUND

Despite the known benefits of physical activity in cancer survivors, adherence to exercise guidelines remains low. Known barriers to adhering to guidelines include a lack of time and an unwillingness to return to treatment facilities. Virtual exercise programming could assist in mitigating these barriers. This protocol presents a single arm pilot study exploring the feasibility of personalized Zoom-delivered exercise training for breast and prostate cancer survivors. A secondary objective is to determine the preliminary efficacy of participation on body composition, estimated VO_2max, hand grip, one repetition maximum leg press, resting heart rate, resting blood pressure, exercise self-efficacy, and intentions to remain active.

METHODS

Breast (n = 10) and prostate (n = 10) cancer survivors will participate in a 24-week feasibility study, including (1) 12 weeks of one-on-one virtual personal training with an exercise physiologist (EP) via Zoom, and (2) individual exercise for a 12-week follow-up period using recordings of Zoom sessions for guidance. Physical assessments and surveys will be implemented at baseline, 12 weeks, and at the end of the study (24 weeks from baseline).

CONCLUSIONS

While virtual exercise programming became popularized during the pandemic, evidence is still required to understand whether it can successfully address barriers and promote participation.

Study protocol for two pilot randomised controlled trials aimed at increasing physical activity using electrically assisted bicycles to enhance prostate or breast cancer survival

BACKGROUND

In 2020, 1.4 and 2.3 million new cases of prostate cancer and breast cancer respectively were diagnosed globally. In the UK, prostate cancer is the most common male cancer, while breast cancer is the most common female cancer. Engaging in physical activity (PA) is a key component of treatment. However, rates of PA are low in these clinical populations. This paper describes the protocol of CRANK-P and CRANK-B, two pilot randomised controlled trials, involving an e-cycling intervention aimed at increasing PA in individuals with prostate cancer or breast cancer respectively.

METHODS

These two trials are single-centre, stratified, parallel-group, two-arm randomised waitlist-controlled pilot trials in which forty individuals with prostate cancer (CRANK-P) and forty individuals with breast cancer (CRANK-B) will be randomly assigned, in a 1:1 allocation ratio, to an e-cycling intervention or waitlist control. The intervention consists of e-bike training with a certified cycle instructor, followed by the provision of an e-bike for 12 weeks. Following the intervention period, participants in the e-bike condition will be directed to community-based initiatives through which they can access an e-bike. Data will be collected at baseline (T0), immediately post intervention (T1) and at 3-month follow-up (T2). In addition, in the intervention group, data will be collected during the intervention and follow-up periods. Quantitative and qualitative methods will be used. The primary objectives are to determine effective recruitment strategies, establish recruitment and consent rates, adherence and retention in the study, and determine the feasibility and acceptability of the study procedures and intervention. The potential impact of the intervention on clinical, physiological and behavioural outcomes will be assessed to examine intervention promise. Data analyses will be descriptive.

DISCUSSION

The findings from these trials will provide information on trial feasibility and highlight the potential of e-cycling as a strategy to positively impact the health and behaviour of individuals with prostate cancer and breast cancer. If appropriate, this information can be used to design and deliver a fully powered definitive trial.

[Physical activity and lung cancer: A synthesis of the literature]

INTRODUCTION

Physical activity (PA) has its place in the continuum of care, the objective being to limit alterations associated with cancer and its treatments. This review of the literature collates the evidence and current data relating to PA carried out at different periods of treatment for lung cancer.

STATE OF THE ART

PA is safe and feasible in patients with lung cancer throughout their oncologic treatment. The efficacy of multimodal programs is demonstrated regarding symptoms, exercise capacity, functional capacity, postoperative complications, length of hospital stay and quality of life. Nevertheless, this result remains to be confirmed with more robust upcoming trial, notably in the long term.

PERSPECTIVES

Utilization of activity and energy expenditure sensors or PA questionnaires could help to increase the PA level of lung cancer patients during their continuum of care. For those not at ease with conventional training modalities, it may be judicious to offer intermittent high-intensity training or respiratory muscle strength training. Telerehabilitation could also be implemented. The targeting of populations at high risk should be investigated.

CONCLUSION

Teams caring for patients with lung cancer during or after their oncologic treatment should develop innovative strategies designed to overcome difficulties of access or adherence to exercise programs, so that the PA be an integral part of the care of these patients. Physical therapists play an important role in supporting these patients during their assessment or treatment.

Effectiveness of personalized treatment stage-adjusted digital therapeutics in colorectal cancer: a randomized controlled trial

BACKGROUND

Colorectal cancer survivors often experience decline in physical performance and poor quality of life after surgery and during adjuvant therapies. In these patients, preserving skeletal muscle mass and high-quality nourishment are essential to reduce postoperative complications and improve quality of life and cancer-specific survival. Digital therapeutics have emerged as an encouraging tool for cancer survivors. However, to the best of our knowledge, randomized clinical trials applying personalized mobile application and smart bands as a supportive tool to several colorectal patients remain to be conducted, intervening immediately after the surgical treatment.

METHODS

This study is a prospective, multi-center, single-blinded, two-armed, randomized controlled trial. The study aims to recruit 324 patients from three hospitals. Patients will be randomly allocated to two groups for one year of rehabilitation, starting immediately after the operation: a digital healthcare system rehabilitation (intervention) group and a conventional education-based rehabilitation (control) group. The primary objective of this protocol is to clarify the effect of digital healthcare system rehabilitation on skeletal muscle mass increment in patients with colorectal cancer. The secondary outcomes would be the improvement in quality of life measured by EORTC QLQ C30 and CR29, enhanced physical fitness level measured by grip strength test, 30-sec chair stand test and 2-min walk test, increased physical activity measured by IPAQ-SF, alleviated pain intensity, decreased severity of the LARS, weight, and fat mass. These measurements will be held on enrollment and at 1, 3, 6 and 12 months thereafter.

DISCUSSION

This study will compare the effect of personalized treatment stage-adjusted digital health interventions on immediate postoperative rehabilitation with that of conventional education-based rehabilitation in patients with colorectal cancer. This will be the first randomized clinical trial performing immediate postoperative rehabilitation in a large number of patients with colorectal cancer with a tailored digital health intervention, modified according to the treatment phase and patient condition. The study will add foundations for the application of comprehensive digital healthcare programs focusing on individuality in postoperative rehabilitation of patients with cancer.

The Future of Breast Cancer Research in the Survivorship Field

Prevalence of survivors of breast cancer has been steadily increasing in the last 20 years. Currently, more than 90% of women diagnosed with early-stage breast cancer are expected to be alive at 5 years from diagnosis thanks to early detection and breakthrough innovations in multimodal treatment strategies. Alongside this advancement in clinical outcomes, survivors of breast cancer might experience several specific challenges and present with unique needs. Survivorship trajectories after diagnosis and treatment of breast cancer can be significantly impacted by long-lasting and severe treatment-related side effects, including physical problems, psychological distress, fertility issues in young women, and impaired social and work reintegration, which add up to patients' individual risk of cancer recurrence and second primary malignancies. Alongside cancer-specific sequelae, survivors still present with general health needs, including management of chronic preexisting or ensuing conditions. Survivorship care should implement high-quality, evidence-based strategies to promptly screen, identify, and address survivors' needs in a comprehensive way and minimize the impact of severe treatment sequelae, preexisting comorbidities, unhealthy lifestyles, and risk of recurrence on quality of life. This narrative review focuses on core areas of survivorship care and discuss the state of the art and future research perspectives in key domains including selected long-term side effects, surveillance for recurrences and second cancers, well-being promotion, and specific survivors' needs.

Early postoperative gain in activity levels of lower extremity sarcoma survivors positively affects long-term physical activity and performance

PURPOSE

Little is known about the effect of sports activity levels on health-related quality of life (HRQOL) in long-term survivors of lower-extremity sarcoma.

METHODS

Eighty-three long-term survivors of bone and soft tissue sarcoma of the lower extremities with a median follow-up of 14 (range: 5-35) years completed the University of California and Los Angeles (UCLA) activity scores before tumor resection, 1 year after surgery and at the latest follow-up, as well as a Short Form 36 (SF-36) health survey at the latest follow-up. Simple linear regression models as well as stepwise variable selection with Akaike information criterion (AIC) were undertaken.

RESULTS

The preoperative UCLA activity level (median: 9, range: 2-10) dropped to a median of 4 (range: 1-10) 1 year after surgery before increasing to a score of 6 (range: 2-10) 5 years after surgery. The long-term SF-36 physical health component summary score (PCS) was 49 (SD: 9), and the mental health component summary score (MCS) was 54 (SD: 7). A linear model with stepwise variable selection identified a negative correlation of PCS with age at surgery (estimate: -0.2; p = 0.02), UCLA score at the last follow-up (estimate: 1.4; p = 0.02) and UCLA score 1 year after surgery (estimate: 1.0; p = 0.02).

CONCLUSION

As not only the final activity levels but also the status immediately after surgery affect the PCS, higher early activity levels should be a goal of modern rehabilitation after sarcoma treatment. Further studies are needed to weigh the potential postoperative risks of higher sport activity levels against the benefits described in this study.
