RESUMO
BACKGROUND: Structured exercise has an important role in mitigating the extensive side effects caused by ongoing prostate cancer treatments, specifically androgen deprivation therapy (ADT) and radiation therapy (RT). Little is known about men's experiences of, and preferences for, structured exercise programmes during active cancer treatment. This study aimed to inform the acceptability of a 6-month supervised intervention that emphasised increasing and varied intensities of aerobic and resistance exercise, by exploring the experiences of men who participated. METHODS: Individual semi-structured interviews were conducted with an interviewer independent of the exercise study and data was analysed using a descriptive qualitative design. RESULTS: Twelve prostate cancer patients were interviewed including participants who completed (n = 9) and withdrew from (n = 3) the intervention. Four main themes captured how men experienced the intervention: (1) Navigating the Unknown: Building confidence amidst vulnerability (subtheme- pushing the limits), (2) Building Trust: The credibility and approach of the exercise instructor (subtheme- appropriateness of supervised vs. independent exercise), (3) Flexibility in Delivery, (4) Finding Purpose: Exercise as a means of escapism and regaining control during treatment. CONCLUSION: While an initial lack of self-confidence can be a barrier to exercise participation, exercise programmes have the potential to provide psychosocial benefits, rebuild confidence and empower men throughout their cancer treatment and into recovery. Structured exercise is acceptable during treatment including RT and can offer a form of escapism and sense of control for men navigating their cancer journey. Trust building, flexible delivery and credibility alongside a challenging exercise prescription are important facilitators of acceptability for men. Strategies to embed exercise from the point of diagnosis through ADT and RT should reflect men's experiences of exercise during treatment. TRIAL REGISTRATION: The trial has been registered on ClinicalTrials.gov as of the 14th of December 2021 (NCT05156424).

BACKGROUND: High levels of physical activity are associated with reduced risk of the blood cancer multiple myeloma (MM). MM is preceded by the asymptomatic stages of monoclonal gammopathy of undetermined significance (MGUS) and smouldering multiple myeloma (SMM) which are clinically managed by watchful waiting. A case study (N = 1) of a former elite athlete aged 44 years previously indicated that a multi-modal exercise programme reversed SMM disease activity. To build from this prior case study, the present pilot study firstly examined if short-term exercise training was feasible and safe for a group of MGUS and SMM patients, and secondly investigated the effects on MGUS/SMM disease activity. METHODS: In this single-arm pilot study, N = 20 participants diagnosed with MGUS or SMM were allocated to receive a 16-week progressive exercise programme. Primary outcome measures were feasibility and safety. Secondary outcomes were pre- to post-exercise training changes to blood biomarkers of MGUS and SMM disease activity- monoclonal (M)-protein and free light chains (FLC)- plus cardiorespiratory and functional fitness, body composition, quality of life, blood immunophenotype, and blood biomarkers of inflammation. RESULTS: Fifteen (3 MGUS and 12 SMM) participants completed the exercise programme. Adherence was 91 ± 11%. Compliance was 75 ± 25% overall, with a notable decline in compliance at intensities > 70% VÌO2PEAK. There were no serious adverse events. There were no changes to M-protein (0.0 ± 1.0 g/L, P =.903), involved FLC (+ 1.8 ± 16.8 mg/L, P =.839), or FLC difference (+ 0.2 ± 15.6 mg/L, P =.946) from pre- to post-exercise training. There were pre- to post-exercise training improvements to diastolic blood pressure (- 3 ± 5 mmHg, P =.033), sit-to-stand test performance (+ 5 ± 5 repetitions, P =.002), and energy/fatigue scores (+ 10 ± 15%, P =.026). Other secondary outcomes were unchanged. CONCLUSIONS: A 16-week progressive exercise programme was feasible and safe, but did not reverse MGUS/SMM disease activity, contrasting a prior case study showing that five years of exercise training reversed SMM in a 44-year-old former athlete. Longer exercise interventions should be explored in a group of MGUS/SMM patients, with measurements of disease biomarkers, along with rates of disease progression (i.e., MGUS/SMM to MM).

OBJECTIVE: To review the body of evidence on cardiorespiratory fitness, muscle strength, and physical performance in children with newly diagnosed cancer, five databases (MEDLINE, Embase, CINAHL, CENTRAL, and Web of Science) were searched on December 19, 2022. METHODS: Thirteen studies, embodying 594 participants within 1 month of cancer diagnosis and 3674 healthy controls were included. Eighteen different outcomes on cardiorespiratory fitness (n = 2), muscle strength (n = 5), physical performance (n = 10), and adverse events (n = 1) were analyzed. RESULTS: Fifteen out of 17 outcomes on physical capacity showed severe impairments compared with healthy controls. Where possible, random-effects meta-analysis was conducted to synthesize the results. No adverse events were reported related to testing. CONCLUSION: Children with cancer have impaired cardiorespiratory fitness, muscle strength, and physical performance within the first month after diagnosis. However, the evidence is based on a small number of studies with large clinical heterogeneity, limiting the certainty of evidence.

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.

PURPOSE: Exercise prehabilitation aims to increase preoperative fitness, reduce post-operative complications, and improve health-related quality of life. For prehabilitation to work, access to an effective programme which is acceptable to stakeholders is vital. The aim was to explore acceptability of exercise prehabilitation before cancer surgery among key stakeholders specifically patients, family members and healthcare providers. METHODS: A mixed-methods approach (questionnaire and semi-structured interview) underpinned by the Theoretical Framework of Acceptability was utilised. Composite acceptability score, (summation of acceptability constructs and a single-item overall acceptability construct), and median of each construct was calculated. Correlation analysis between the single-item overall acceptability and each construct was completed. Qualitative data was analysed using deductive and inductive thematic analysis. RESULTS: 244 participants completed the questionnaire and n=31 completed interviews. Composite acceptability was comparable between groups (p=0.466). Four constructs positively correlated with overall acceptability: affective attitude (r=0.453), self-efficacy (r=0.399), ethicality (r=0.298) and intervention coherence (r=0.281). Qualitative data confirmed positive feelings, citing psychological benefits including a sense of control. Participants felt flexible prehabilitation program would be suitable for everyone, identifying barriers and facilitators to reduce burden. CONCLUSION: Exercise prehabilitation is highly acceptable to key stakeholders. Despite some burden, it is a worthwhile and effective intervention. Stakeholders understand its purpose, are confident in patients' ability to participate, and regard it is an important intervention contributing to patients' psychological and physical wellbeing. IMPLICATIONS: â¢Introduction should be comprehensively designed and clearly presented, providing appropriate information and opportunity for questions. â¢Programmes should be patient-centred, designed to overcome barriers and address patients' specific needs and goals. â¢Service must be appropriately resourced with a clear referral-pathway.

INTRODUCTION: Symptoms during cancer treatment cause burden, diminished physical functioning, and poor quality of life. Exercise is recommended during treatment to mitigate symptoms; however, interventions are difficult to translate into clinical care due to the lack of patient uptake and clinical implementation barriers. We evaluated the uptake, acceptability, and impact of an automated ePRO exercise module triggered by three patient-reported symptoms: nausea/vomiting, fatigue, and anxiety, during chemotherapy. METHODS: We conducted a secondary analysis of an exercise module intervention imbedded in the cancer symptom monitoring and management platform, Symptom Care at Home (SCH). Utilizing behavioral economics principles, the exercise module was triggered when any of the three symptoms were reported. Once triggered, participants were coached on exercise benefits for symptom reduction and then offered the opportunity to set weekly exercise goals plus tracking of the goal outcomes and receive further encouragement. We examined uptake, exercise goal setting and attainment, and symptom impact. RESULTS: Of 180 SCH participants receiving the SCH intervention, 170 (94.4%) triggered the exercise module and 102 of the 170 (60%) accepted the module, setting goals on average for 6.3 weeks. Of 102 participants, 82 (80.4%) achieved one or more exercise goals, exercising on average 79.8 min/week. Participants who achieved a higher proportion of goals had statistically significant lower overall symptom severity and lower severity of the triggered symptom. CONCLUSION: An automated mHealth exercise coaching intervention, aimed to nudge those receiving chemotherapy to initiate an exercise routine had significant uptake, is acceptable and may reduce symptom severity. TRIAL REGISTRATION: NCT01973946.

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

BACKGROUND: This project aimed to design and evaluate the potential to integrate an exercise oncology service into clinical care in a local healthcare system. The goal was to inform the design of an implementation strategy to promote its sustainable use in standard care. METHODS: This two-phase, exploratory study used a mixed-methods approach. First, qualitative measures were used to understand the context for exercise integration into oncology care by clinicians and administrators in the healthcare system. Next, the Reach, Effectiveness, Adoption, Implementation, Maintenance (RE-AIM) framework guided a comprehensive evaluation of the exercise service. Reach and Adoption were measured via number of patients enrolled in the program relative to those treated. Adoption was measured via referrals from stakeholders. Implementation was described using the program structure and delivery. Maintenance was described using hospital funding decisions. Effectiveness was assessed using the Bellarmine Norton Assessment Tool (BNAT) and Functional Assessment of Cancer Therapy - Fatigue Scale. RESULTS: Phase 1 context analysis suggested critical elements to guide program delivery, including limiting participants to post-primary treatment (surgery, chemotherapy and radiation) and streamlining referral process. The Phase 2 evaluation demonstrated suboptimal program reach (2%); significant program effectiveness (improved physical function (BNAT; p = 0.05 ) and decreased fatigue (p < 0.05)); receptiveness to program adoption (75%); and strong potential for program maintenance. CONCLUSIONS: Traditional approaches to exercise oncology research trials are not easily integrated into healthcare systems. Designing an exercise program for meaningful integration and sustainment requires understanding the context where the program will be delivered, followed by intentional and continuous engagement with key stakeholders to ensure the program continues to meet the needs of the system. Initial exploration of the settings is critical to inform a comprehensive implementation strategy. TRIAL REGISTRATION: clinicaltrials.gov: NCT06039488. Prospectively Registered Sept 15th, 2023.

BACKGROUND: Structured exercise programs provide considerable health benefits for cancer patients. Therefore, various OnkoAktiv (OA) networks were established in Germany with the aim to connect cancer patients with certified exercise programs. However, knowledge about the integration of exercise networks into cancer care systems and conditions of interorganisational collaboration is lacking. The aim of this work was to analyse the OA networks to guide further network development and implementation work. METHODS: We used methods of social network analysis within a cross-sectional study design. Network characteristics were analysed such as node and tie attributes, cohesion and centrality. We classified all networks into their level of organisational form in integrated care. RESULTS: We analysed 11 OA networks with 26 actors and 216 ties on average. The smallest network counted 12 actors/56 ties, the largest 52/530. 76% of all actors operated within the medical/exercise sector, serving 19 different medical professions. In smaller "linkage" networks, several individual professionals were linked "from service to service", whereas the more integrated networks revealed a core-periphery-structure. DISCUSSION: Collaborative networks enable the involvement of professional actors from different operational fields. This study provides an in-depth understanding of underlying organisational structures that provides information for further development of exercise oncology provision. TRIAL REGISTRATION: Not applicable, as no health care intervention was performed.

OBJECTIVES: The purpose of this study was to understand the physical activity (PA) experiences, as well as preferences, barriers, and facilitators to exercise, among individuals of South Asian heritage diagnosed with cancer. DESIGN: A qualitative descriptive design was used. Individuals of South Asian heritage were recruited via a mix of convenience sampling and purposive sampling, with outreach via radio, posters in community settings, and from outreach to participants in current exercise oncology studies. Inclusion criteria included being over the age of 18; diagnosed with any cancer type and stage; pre, during, or post-treatment; able to speak English, Hindi, or Punjabi; and self-identified as South Asian. Data for this study was collected via semi-structured interviews conducted in the participants language of choice. Interviews were transcribed verbatim in the original language and then analyzed using conventional content analysis. For non-English interviews, the codes created through analysis were subsequently translated into English, and back-translated into the original language, to ensure accuracy. These codes were then organized into themes and categories. RESULTS: Eight participants were recruited, with 5 interviews conducted in Punjabi and 3 interviews in English. The three themes that were created from the participant interviews include: (1) Culture, (2) Informational Needs, and (3) The Nature of Exercise Oncology Interventions. Within these themes, categories included barriers and facilitators to PA, as well as PA needs. CONCLUSION: Participants' perspectives provided insights into the PA experiences, barriers, facilitators, and needs of people of South Asian heritage living with and beyond cancer. These results can be used to inform the tailoring of exercise oncology resources to better support physical activity and exercise for this population.

The purpose of this study was to identify referral source and patient-reported factors that promoted follow-through and participation in exercise oncology rehabilitation programs. A three question open-ended survey was administered to patients enrolled in trainer-supervised, hospital-based (n = 101), or university-based (n = 17) cancer rehabilitation program that provided 12 weeks of individualized one on one aerobic and resistance training 1-3 days per week. Significant themes for each question were as follows: Question #1. Who referred you to the program/facility? Oncology team (Χ2 = 145.814 P ≤ 0.001); Question #2. What convinced you to follow through with the referral? Health, fatigue, and need for supervision (Χ2 = 74.814 P ≤ 0.001); and Question #3. What motivates you to continue in the program? Personal results, getting healthy, and the trainer (Χ2 = 108.729 P ≤ 0.001). In this study, oncology team referral confirms previous work. Patient follow-through and continuation appear largely self-motivated as patients' health and the attainment of health through personal results are primary motivators for continuation in the program. Question #3 responses note the importance of the trainer in maintaining continuation in an exercise oncology rehabilitation program.

Epidemiological evidence shows that regular physical activity is associated with reduced risk of primary and recurrent colon cancer. However, the underlying mechanisms of action are poorly understood. We evaluated the effects of stimulating a human colon cancer cell line (LoVo) with human serum collected before and after an acute exercise bout vs nonexercise control serum on cancer cell proliferation. We also measured exercise-induced changes in serum cytokines and intracellular protein expression to explore potential biological mechanisms. Blood samples were collected from 16 men with lifestyle risk factors for colon cancer (age ≥50 years; body mass index ≥25 kg/m2 ; physically inactive) before and immediately after an acute bout of moderate-intensity aerobic interval exercise (6 × 5 minutes intervals at 60% heart rate reserve) and a nonexercise control condition. Stimulating LoVo cells with serum obtained immediately after exercise reduced cancer cell proliferation compared to control (-5.7%; P = .002). This was accompanied by a decrease in LoVo cell γ-H2AX expression (-24.6%; P = .029), indicating a reduction in DNA damage. Acute exercise also increased serum IL-6 (24.6%, P = .002). Furthermore, stimulating LoVo cells with recombinant IL-6 reduced γ-H2AX expression (ß = -22.7%; P < .001) and cell proliferation (ß = -5.3%; P < .001) in a linear dose-dependent manner, mimicking the effect of exercise. These findings suggest that the systemic responses to acute aerobic exercise inhibit colon cancer cell proliferation in vitro, and this may be driven by IL-6-induced regulation of DNA damage and repair. This mechanism of action may partly underlie epidemiological associations linking regular physical activity with reduced colon cancer risk.

PURPOSE: There is limited information on how the COVID-19 pandemic has changed health behaviors among cancer patients. We examined changes in exercise behaviors since the pandemic and identified characteristics associated with these changes among cancer patients. METHODS: Cancer patients (n = 1,210) completed a survey from August to September 2020 to assess COVID-19 pandemic-related changes in health behaviors and psychosocial factors. Patients were categorized into three groups: exercising less, exercising did not change, and exercising more. Patient characteristics were compared by exercise groups. RESULTS: One-third of the patients reported a decreased amount of regular exercise, while 10% reported exercising more during the pandemic. Patients who exercised less were more likely to be unemployed/retired and have poor health status and psychosocial stressors such as disruptions in daily life while less likely to be former smokers (all p < 0.05). In contrast, patients who exercised more were younger, had stage IV diagnosis, and also reported disruptions in daily life (all p < 0.05). Patients who were living in rural areas were also more likely not to experience changes in exercise habits (all p < 0.05), although rural-urban status was not identified as a strong predictor. CONCLUSION: A significant proportion of cancer patients experienced changes in exercise habits, especially exercising less, during the first 6 months of the COVID-19 pandemic. Age, employment status, tumor stage, health status, smoking status, and psychosocial factors were associated with changes in exercise behaviors. Our results highlight the importance of promoting physical activity guidelines for cancer survivorship during the COVID-19 pandemic and may help improve the identification of cancer patients susceptible to exercising less.

PURPOSE OF REVIEW: Chimeric antigen receptor (CAR) T-cell therapy is a relatively new, innovative treatment strategy to manage refractory hematological cancers, including some types of leukemia, lymphoma, and multiple myeloma. This article outlines the CAR T-cell therapy process, toxicity, and complications, along with an overview of the currently known short- and long-term physical and functional sequelae that will be helpful for general or oncology rehabilitation specialists caring for these patients. RECENT FINDINGS: There is a dearth of literature on the topic of rehabilitation of patients receiving CAR T-cell therapy. Rehabilitation practices can be extrapolated from the limited functional information on patients who have completed treatment for lymphoma and multiple myeloma. Patients present with cognitive impairment, muscle weakness, reduced exercise capacity, neuropathy, and cancer-related fatigue. Physical activity and rehabilitation programs may be beneficial to address fatigue, psychological symptoms, and quality of life. There is limited rehabilitation research in patients receiving CAR T-cell therapy. These patients may present with general deconditioning and neurological complications which translate to neuromuscular and cognitive impairment that benefit from multidisciplinary rehabilitation intervention prior to, during, and after treatment. Studies measuring the impairments at baseline and evaluation of the impact of rehabilitation practices are much needed to support this.

BACKGROUND: A better understanding of the role of structural barriers for physical activity (PA) after a cancer diagnosis could help to increase PA among people with cancer. Thus, the present study aimed to identify determinants of structural barriers to PA in people with cancer and investigate the association between structural barriers and insufficient post-diagnosis PA, taking different PA change patterns into account. METHODS: A total of 1299 people with breast, prostate, or colorectal cancer completed a questionnaire assessing their socio-demographic and medical characteristics, pre- and post-diagnosis PA, and perceived PA impediment by seven structural barriers. Regression analyses were used to investigate determinants of the perception of structural barriers and to examine the association between structural barriers and insufficient post-diagnosis PA, also with regard to different pre-diagnosis PA levels. RESULTS: Overall 30-60% of participants indicated to feel impeded by structural barriers. The analyses revealed a younger age, higher BMI, lower educational level, no current work activity, co-morbidities, and lacking physicians' exercise counseling as significant determinants of the perception of structural barriers. Individuals reporting stronger impediments by structural barriers were significantly less likely to be meeting PA guidelines post-diagnosis, particularly those with sufficient pre-diagnosis PA levels. CONCLUSIONS: The study highlights the need for tailored PA programs for people with cancer as well as for more guidance and support in overcoming structural barriers to improve PA behavior. The study has been registered under NCT02678832 at clinicaltrials.gov on February 10th 2016.

BACKGROUND: Although exercise has been shown to improve cancer survivorship in other communities, cancer exercise studies among Native American communities are rare. We sought to adapt a Navajo-tailored cancer exercise pilot program to serve a broader Native American cancer community. METHODS: Tribal experts representing 10 different Tribal Nations were engaged in small focus groups (n=2-4) to assess program materials for cultural appropriateness and adaptation to expand tribal inclusiveness. Facilitated by a trained Native American interviewer, focus groups were provided a primer survey and then reviewed intervention materials (protocols, incentives, logo, flyers, etc.). Consensus was reached by the research team on all program adaptations. RESULTS: The program name, Restoring Balance, layout, graphics, and symbols were considered culturally appropriate overall. Program exercises and biomarker measurements were viewed as valuable to health improvements in the community. Important color, linguistic, and logistic program modifications were recommended to improve cultural alignment. The order of incentive items was revised to highlight restoration and the logo rotated to align with the four corners of the earth, an important cultural element. Linguistic modifications primarily related to prior traumatic research experiences in Native American communities where data had been taken without adequate community benefit or permission. Program emphasis should be on nurturing, added value and giving. CONCLUSION AND RELEVANCE: The methodology used for cultural expert review was successful in eliciting adaptations to expand the tribal inclusiveness of Restoring Balance. Culture, as well as historically traumatic research experiences, among Native American populations must be considered when adapting health promotion programming.
RESUMO
BACKGROUND: Multiple international organizations have called for exercise to become standard practice in the setting of oncology care. The feasibility of integrating exercise within systemic chemotherapy has not been investigated. METHODS: Patients slated to receive infusion therapy between April 2017 and October 2018 were screened for possible inclusion. The study goal was to establish the acceptability and feasibility of embedding an exercise professional into the chemotherapy infusion suite as a method of making exercise a standard part of cancer care. The exercise prescriptions provided to patients were individualized according to results of brief baseline functional testing. RESULTS: In all, 544 patients were screened, and their respective treating oncologists deemed 83% of them to be medically eligible to participate. After further eligibility screening, 226 patients were approached. Nearly 71% of these patients (n = 160) accepted the invitation to participate in the Exercise in All Chemotherapy trial. Feasibility was established because 71%, 55%, 69%, and 63% of the aerobic, resistance, balance, and flexibility exercises prescribed to patients were completed. Qualitative data also supported the acceptability and feasibility of the intervention from the perspective of patients and clinicians. The per-patient cost of the intervention was $190.68 to $382.40. CONCLUSIONS: Embedding an exercise professional into the chemotherapy infusion suite is an acceptable and feasible approach to making exercise standard practice. Moreover, the cost of the intervention is lower than the cost of other common community programs. Future studies should test whether colocating an exercise professional with infusion therapy could reach more patients in comparison with not colocating. LAY SUMMARY: Few studies have tested the implementation of exercise for patients with cancer by embedding an exercise professional directly into the chemotherapy infusion suite. The Exercise in All Chemotherapy trial shows that this approach is both acceptable and feasible from the perspective of clinicians and patients.

The purpose of this paper is to introduce a novel in silico platform for simulating early-stage solid tumor growth and anti-tumor immune response. We present the model, test the sensitivity and robustness of its parameters, and calibrate it with clinical data from exercise oncology experiments which offer a natural biological backdrop for modulation of anti-tumor immune response. We then perform two virtual experiments with the model that demonstrate its usefulness in guiding pre-clinical and clinical studies of immunotherapy. The first virtual experiment describes the intricate dynamics in the tumor microenvironment between the tumor and the infiltrating immune cells. Such dynamics is difficult to probe during a pre-clinical study as it requires significant redundancy in lab animals and is prohibitively time-consuming and labor-intensive. The result is a series of spatiotemporal snapshots of the tumor and its microenvironment that can serve as a platform to test mechanistic hypotheses on the role and dynamics of different immune cells in anti-tumor immune response. The second virtual experiment shows how dosage and/or frequency of immunotherapy drugs can be optimized based on the aerobic fitness of the patient, so that possible adverse side effects of the treatment can be minimized.

BACKGROUND: Advanced lung cancer patients face significant physical and psychological burden leading to reduced physical function and quality of life. Separately, physical activity, nutrition, and palliative symptom management interventions have been shown to improve functioning in this population, however no study has combined all three in a multimodal intervention. Therefore, we assessed the feasibility of a multimodal physical activity, nutrition, and palliative symptom management intervention in advanced lung cancer. METHODS: Participants received an individually tailored 12-week intervention featuring in-person group-based exercise classes, at-home physical activity prescription, behaviour change education, and nutrition and palliative care consultations. Patients reported symptom burden, energy, and fatigue before and after each class. At baseline and post-intervention, symptom burden, quality of life, fatigue, physical activity, dietary intake, and physical function were assessed. Post-intervention interviews examined participant perspectives. RESULTS: The multimodal program was feasible, with 44% (10/23) recruitment, 75% (75/100) class attendance, 89% (8/9) nutrition and palliative consult attendance, and 85% (17/20) assessment completion. Of ten participants, 70% (7/10) completed the post-intervention follow-up. Participants perceived the intervention as feasible and valuable. Physical activity, symptom burden, and quality of life were maintained, while tiredness decreased significantly. Exercise classes prompted acute clinically meaningful reductions in fatigue, tiredness, depression, pain, and increases in energy and well-being. CONCLUSION: A multimodal physical activity, nutrition, and palliative symptom management intervention is feasible and shows potential benefits on quality of life that warrant further investigation in a larger cohort trial. TRIAL REGISTRATION: NCT04575831 , Registered 05 October 2020 - Retrospectively registered.

PURPOSE: To assess the impact of the Personal Optimism With Exercise Recovery (POWER) program on cancer treatment-related side effects among rural cancer survivors. METHODS: In this retrospective study of data collected between 2016 and 2019, we assessed change in cardiorespiratory fitness, whole-body muscular endurance, physical function and strength, anthropometrics, fatigue, and quality of life (QoL), after participation in POWER. Descriptive statistics were calculated for demographic and clinical variables. Univariate analysis of variance was carried out with age and BMI at initial assessment as covariates. RESULTS: A total of 239 survivors, 78% rural residents, completed a follow-up assessment. Among rural cancer survivors, the most prevalent cancer sites were breast (42.5%), prostate (12.4%), and lymphoma (5.9%). The majority of survivors were female (70%), non-Hispanic (94.6%), and white (93.5%), with average age and BMI of 62.1 ± 13.2 years and 28.4 ± 6.7 kg/m2, respectively. Rural cancer survivors with cancer stages I-III exhibited significant improvements in fitness (+ 3.07 ml/kg/min, 95% CI 1.93, 4.21; + 0.88 METS, 95% CI 0.55, 1.20), physical function (30-s chair stand: + 2.2 repetitions, 95% CI 1.3, 3.1), muscular endurance (10-repetition maximum: chest press + 4.1 kg, 95% CI 2.0, 6.3; lateral pulldown + 6.6 kg, 95% CI 4.4, 8.9), self-reported fatigue (FACIT-Fatigue score: + 4.9, 95% CI 1.6, 8.1), and QoL (FACT-G7 score + 2.1, 95% CI, 0.9, 3.4). Among stage IV rural and urban cancer survivors, significant improvements were observed in muscular endurance and physical function. CONCLUSION: Participation in POWER was associated with attenuation of cancer treatment-related side effects and may serve as a model exercise oncology program for rural cancer survivors.
