Physical activity in patients with non-small cell lung cancer after lung resection

BACKGROUND

Lung resection is the standard of care for patients with clinical stage I/II non-small cell lung cancer. This surgery reduces both the duration and quality of patients' daily ambulatory activities 1 month after surgery. However, little is known about physical activity after lung resection in patients with lung cancer. To evaluate the recovery process of physical activity with pulmonary rehabilitation in patients after lung resection and examine whether physical activity is affected by age.

METHODS

In this prospective, observational study, we measured and analysed participants' postoperative physical activity using a uniaxial accelerometer daily from postoperative day 1 to 30.

FINDINGS

We analysed 99 patients who underwent thoracic surgery. The number of walking steps significantly increased until day 4 and then reached a plateau thereafter. The duration of exercise at <3 metabolic equivalents significantly increased until day 3, and no significant difference was observed thereafter. Exercise at >3 metabolic equivalents significantly increased until day 4 and reached a plateau thereafter. A significant correlation was observed between age and number of steps after day 4. Compared with video-assisted thoracoscopic surgery, thoracotomy significantly decreased the number of steps from day 3 to 4.

INTERPRETATION

We found that the level of physical activity varied by index in patients with non-small cell lung cancer who underwent lung resection. Age and surgical procedure affect different periods with the increase in post-operative walking steps.

Safety and efficacy evaluation of personalized exercise prescription during chemotherapy for lung cancer patients

BACKGROUND

To explore the safety and effectiveness of personalized exercise intervention during chemotherapy for lung cancer patients who were relatively weak and with compromised cardiopulmonary function.

METHODS

Thirty-eight lung cancer patients treated with chemotherapy at Peking University Third Hospital were enrolled in this prospective study. The exercise group (N = 21) received individualized exercise guidance based on personal test results and exercised regularly, while the control group (N = 17) only received exercise education and planed exercise methods according to their own preferences. Both groups underwent three fitness tests and clinical indicator assessments at 0, 6, and 12 weeks after starting the exercise, and the differences in trends of various indicators between the two groups were compared.

RESULTS

No exercise-related adverse events occurred during the 12-week exercise period. After 12 weeks of exercise training, in terms of fitness, the exercise group showed significant improvements in 6-min walk test (6MWT) (p < 0.001), peak oxygen consumption (VO2peak) (p = 0.005), muscle content (p < 0.001), muscle percentage (p < 0.001), and grip strength (p = 0.008) compared to the control group. In terms of clinical indicators, the exercise group showed significant improvements in vital capacity (p = 0.018), D-dimer (p = 0.031), and C-reactive protein (CRP) (p = 0.01), uric acid (p = 0.003), triglycerides (p < 0.001), functional average score (p < 0.001), and main symptom average score (p = 0.004) compared to the control group in trends over time.

CONCLUSION

Rehabilitation exercises using individualized exercise prescriptions tailored by exercise prescription specialists during chemotherapy are safe for lung cancer patients. Adhering to exercise can achieve comprehensive improvements in physical fitness and quality of life at 12 weeks.

Harnessing the Systemic Biology of Functional Decline and Cachexia to Inform more Holistic Therapies for Incurable Cancers

Options for treatment of incurable cancer remain scarce and are largely focused on limited therapeutic mechanisms. A new approach specific to advanced cancers is needed to identify new and effective treatments. Morbidity in advanced cancer is driven by functional decline and a number of systemic conditions, including cachexia and fatigue. This review will focus on these clinical concepts, describe our current understanding of their underlying biology, and then propose how future therapeutic strategies, including pharmaceuticals, exercise, and rehabilitation, could target these mechanisms as an alternative route to addressing incurable cancer.

Nurse navigation, symptom monitoring and exercise in vulnerable patients with lung cancer: feasibility of the NAVIGATE intervention

We developed the Navigate intervention to improve survival among vulnerable lung cancer patients. In this intervention-only study, we examined feasibility in terms of recruitment, retention, attendance, adherence, and acceptability to specify adjustments to study procedures and intervention components prior to a randomized trial. The Navigate intervention includes nurse navigation, patient-reported outcomes, and physical exercise. Patients ≥ 18 years old, diagnosed with non-small cell lung cancer at any stage, with performance status ≤ 2, eligible for cancer treatment and vulnerable according to a screening instrument were included. The recruitment goal of eligible patients was 40% while the retention goal was 85%. The predefined cut-offs for sufficient attendance and adherence were ≥ 75%. Acceptability was evaluated by semi-structured interviews with participants, nurse navigators, and physiotherapists. Seventeen (56%) out of 30 screened patients were considered vulnerable and eligible for the study, 14 (82%) accepted participation, and 3 (21%) were subsequently excluded due to ineligibility, leaving 11 patients. Four patients dropped out (36%) and four patients died (36%) during follow-up and 3 (27%) were retained. All 11 patients participated in nurse sessions (mean 16, range 1-36) with 88% attendance and dialogue tools being applied in 68% of sessions. Ninety-one percent of patients responded to PROs (mean of 9 PROs, range 1-24) with 76% of the PRO questionnaires used (attendance) and 100% adherence (completion of all questions in PRO questionnaires), and 55% participated in exercise sessions with 58% attendance and 85% adherence. We identified important barriers primarily related to transportation, but overall acceptability was high. The Navigate intervention was feasible with high participation, acceptability and satisfactory adherence. Retention and exercise attendance were low, which resulted in adjustments.Trial registration: The feasibility study was initiated prior to the multicenter randomized controlled trial registered by ClinicalTrials.gov (number: NCT05053997; date 23/09/2021).

Exploring the feasibility of a combined exercise program for patients with advanced lung or pancreatic cancer

Objective

This study aims to assess the safety, feasibility, and potential benefits of a combined aerobic and resistance exercise intervention for patients diagnosed with advanced pancreatic or lung cancer.

Methods

A prospective, single-arm study was conducted, enrolling patients with advanced lung or pancreatic cancer. Participants engaged in a 12-week exercise intervention comprising personalized bi-weekly aerobic and resistance training tailored to individual baseline conditions. The primary study outcomes focused on safety (absence of serious adverse events) and feasibility. Secondary outcomes included assessments of functional capacity using the "Six minutes walking test", strength measured through handgrip and leg press tests, anthropometric measures including body mass index and waist-hip ratio, quality of life (QoL), and changes in blood parameters.

Results

The study involved twelve patients (mean age 57.66 ​± ​7.40 years), with seven having pancreatic cancer and five having lung cancer. The recruitment rate was 50%, and assessment adherence was 100%, with an 84% adherence to the exercise program and no dropouts. No exercise-related adverse events were recorded, while three non-severe, non-exercise-related adverse events were observed: treatment-related dermatitis (Grade 2), axillary lymphadenopathy (Grade 2), and migraine (Grade 1). Significant enhancements in functional capacity, emotional well-being, and social functioning within the QoL domains were observed. Anthropometric measures, specifically waist-hip ratio and body mass index, remained stable.

Conclusions

The findings suggest that a tailored 12-week exercise intervention is both feasible and safe for patients with advanced lung or pancreatic cancer. This intervention appears to enhance functional capacity, specific aspects of QoL, and contribute to maintaining body weight.

Nurse-Supervised Exercise for People with Stage IV Cancer: The EFICANCER Randomized Clinical Trial

OBJECTIVES

To assess the effectiveness of the EFICANCER individualized and supervised exercise program for people with gastrointestinal, breast, or non-small cell lung stage IV cancer, in terms of quality of life and functional capacity.

DATA SOURCES

Randomized controlled clinical trial with two parallel groups: EFICANCER (n = 47) and control (n = 43). Both groups received standard oncological care. In addition, the EFICANCER group participated in a nurse-supervised exercise program. Primary outcome was cancer-specific (EORTC QLQ-C30 questionnaire) and general quality of life (SF-36) at baseline and after 2, 6, and 12 months. Secondary outcomes were functional capacity (6-minute walking test), strength, and fatigue. The evolution in both groups was compared over 12 months using mixed-effect longitudinal models; 74.47% of patients completed at least one session of the program. At 12 months, EFICANCER group had better scores in cancer-related quality of life, with a difference between groups of 15.7 points (95% confidence interval 4.4 to 25.9) and in functional capacity, with a difference of 4.5 points (95% confidence interval -0.5 to 9.5). No significant differences in any other secondary variables were observed.

CONCLUSION

The EFICANCER primary care nurse supervised exercise program is safe and feasible and improves cancer patient's outcomes.

IMPLICATIONS FOR NURSING PRACTICE

Providing the best care and trying to improve the quality of life of cancer patients are essential parts of nursing practice. Eficancer adds a new dimension to nursing practice by providing greater attention and care to patients during treatment through the supervision of physical exercise, thereby contributing to improve the quality of life of this population.

Exercise Rehabilitation and Chronic Respiratory Diseases: Effects, Mechanisms, and Therapeutic Benefits

Chronic respiratory diseases (CRD), is a group of disorders, primarily chronic obstructive pulmonary disease and asthma, which are characterized by high prevalence and disability, recurrent acute exacerbations, and multiple comorbidities, resulting in exercise limitations and reduced health-related quality of life. Exercise training, an important tool in pulmonary rehabilitation, reduces adverse symptoms in patients by relieving respiratory limitations, increasing gas exchange, increasing central and peripheral hemodynamic forces, and enhancing skeletal muscle function. Aerobic, resistance, and high-intensity intermittent exercises, and other emerging forms such as aquatic exercise and Tai Chi effectively improve exercise capacity, physical fitness, and pulmonary function in patients with CRD. The underlying mechanisms include enhancement of the body's immune response, better control of the inflammatory response, and acceleration of the interaction between the vagus and sympathetic nerves to improve gas exchange. Here, we reviewed the new evidence of benefits and mechanisms of exercise intervention in the pulmonary rehabilitation of patients with chronic obstructive pulmonary disease, bronchial asthma, bronchiectasis, interstitial lung disease, and lung cancer.

Cancer-related Fatigue in Lung Cancer: A Research Agenda: An Official American Thoracic Society Research Statement

Background: Fatigue is the most common symptom among cancer survivors. Cancer-related fatigue (CRF) may occur at any point in the cancer care continuum. Multiple factors contribute to CRF development and severity, including cancer type, treatments, presence of other symptoms, comorbidities, and medication side effects. Clinically, increasing physical activity, enhancing sleep quality, and recognizing sleep disorders are integral to managing CRF. Unfortunately, CRF is infrequently recognized, evaluated, or treated in lung cancer survivors despite more frequent and severe symptoms than in other cancers. Therefore, increased awareness and understanding of CRF are needed to improve health-related quality of life in lung cancer survivors. Objectives: 1) To identify and prioritize knowledge and research gaps and 2) to develop and prioritize research questions to evaluate mechanistic, diagnostic, and therapeutic approaches to CRF among lung cancer survivors. Methods: We convened a multidisciplinary panel to review the available literature on CRF, focusing on the impacts of physical activity, rehabilitation, and sleep disturbances in lung cancer. We used a three-round modified Delphi process to prioritize research questions. Results: This statement identifies knowledge gaps in the 1) detection and diagnostic evaluation of CRF in lung cancer survivors; 2) timing, goals, and implementation of physical activity and rehabilitation; and 3) evaluation and treatment of sleep disturbances and disorders to reduce CRF. Finally, we present the panel's initial 32 research questions and seven final prioritized questions. Conclusions: This statement offers a prioritized research agenda to 1) advance clinical and research efforts and 2) increase awareness of CRF in lung cancer survivors.

The impact of prehabilitation interventions on affective and functional outcomes for young to midlife adult cancer patients: A systematic review

OBJECTIVE

Cancer remains one of the most enduring health crises of the modern world. Prehabilitation is a relatively new intervention aimed at preparing individuals for the stresses associated with treatment from diagnosis. Prehabilitation can include exercise, psychological and nutrition-based interventions. The present systematic review aimed to assess the efficacy of prehabilitation on affective and functional outcomes for young to midlife adult cancer patients (18-55 years). Outcomes of interest included prehabilitation programme composition, duration, mode of delivery and measures used to determine impact on affective and functional outcomes.

METHODS

The following databases were searched with controlled and free text vocabulary; Psychological Information database (PsychINFO), Culmunated Index to Nursing and Allied Health Literature (CINAHL), Medical Literature Analysis and Retrieval System Online (MEDLINE), Excerpta Medica Database (EMBASE) and Public MEDLINE (PubMed). Abstract and full-text screening was conducted with a secondary reviewer and final texts were subject to risk of bias analysis.

RESULTS

Thirteen texts were included at full-text. These included data of 797 prehabilitation participants (mean age 53 years) and a large representation of female participants (71% average). Evidence was found for the efficacy of psychological prehabilitation for anxiety reduction. Prehabilitation did not significantly affect health related quality of life. Findings moderately supported the therapeutic validity of exercise prehabilitation for functional outcomes, both in terms of clinical and experimental improvement with respect to the quality of evidence. Variation between all prehabilitation types was observed. There was insufficient evidence to support the efficacy of psychological prehabilitation on stress, distress or depression.

CONCLUSION

Implications for future research are highlighted and then discussed with respect to this young to midlife age group.

Systematic Review of Functional Outcomes in Cancer Rehabilitation

OBJECTIVE

To systematically review the evidence regarding rehabilitation interventions targeting optimal physical or cognitive function in adults with a history of cancer and describe the breadth of evidence as well as strengths and limitations across a range of functional domains.

DATA SOURCES

PubMed, Cumulative Index to Nursing and Allied Health Plus, Scopus, Web of Science, and Embase. The time scope was January 2008 to April 2019.

STUDY SELECTION

Prospective, controlled trials including single- and multiarm cohorts investigating rehabilitative interventions for cancer survivors at any point in the continuum of care were included, if studies included a primary functional outcome measure. Secondary data analyses and pilot/feasibility studies were excluded. Full-text review identified 362 studies for inclusion.

DATA EXTRACTION

Extraction was performed by coauthor teams and quality and bias assessed using the American Academy of Neurology (AAN) Classification of Evidence Scheme (class I-IV).

DATA SYNTHESIS

Studies for which the functional primary endpoint achieved significance were categorized into 9 functional areas foundational to cancer rehabilitation: (1) quality of life (109 studies), (2) activities of daily living (61 studies), (3) fatigue (59 studies), (4) functional mobility (55 studies), (5) exercise behavior (37 studies), (6) cognition (20 studies), (7) communication (10 studies), (8) sexual function (6 studies), and (9) return to work (5 studies). Most studies were categorized as class III in quality/bias. Averaging results found within each of the functional domains, 71% of studies reported statistically significant results after cancer rehabilitation intervention(s) for at least 1 functional outcome.

CONCLUSIONS

These findings provide evidence supporting the efficacy of rehabilitative interventions for individuals with a cancer history. The findings should be balanced with the understanding that many studies had moderate risk of bias and/or limitations in study quality by AAN criteria. These results may provide a foundation for future work to establish clinical practice guidelines for rehabilitative interventions across cancer disease types.

Psychosocial Aspects of Living Long Term with Advanced Cancer and Ongoing Systemic Treatment: A Scoping Review

(1) Background: Studies examining the psychosocial impact of living long term on systemic treatment in advanced cancer patients are scarce. This scoping review aimed to answer the research question “What has been reported about psychosocial factors among patients living with advanced cancer receiving life-long systemic treatment?”, by synthesizing psychosocial data, and evaluating the terminology used to address these patients; (2) Methods: This scoping review was conducted following the five stages of the framework of Arksey and O’Malley (2005); (3) Results: 141 articles published between 2000 and 2021 (69% after 2015) were included. A large variety of terms referring to the patient group was observed. Synthesizing qualitative studies identified ongoing uncertainty, anxiety and fear of disease progression or death, hope in treatment results and new treatment options, loss in several aspects of life, and worries about the impact of disease on loved ones and changes in social life to be prominent psychosocial themes. Of 82 quantitative studies included in the review, 76% examined quality of life, 46% fear of disease progression or death, 26% distress or depression, and 4% hope, while few studies reported on adaptation or cognitive aspects. No quantitative studies focused on uncertainty, loss, or social impact; (4) Conclusion and clinical implications: Prominent psychosocial themes reported in qualitative studies were not included in quantitative research using specific validated questionnaires. More robust studies using quantitative research designs should be conducted to further understand these psychological constructs. Furthermore, the diversity of terminology found in the literature calls for a uniform definition to better address this specific patient group in research and in practice.

Developing a visual model for predicting depression in patients with lung cancer

AIMS AND OBJECTIVES

To investigate and analyse the prevalence of depression among patients with lung cancer, identify risk factors of depression, and develop a visual, non-invasive, and straightforward clinical prediction model that can be used to predict the risk probability of depression in patients with lung cancer quantitatively.

BACKGROUND

Depression is one of the common concomitant symptoms of patients with lung cancer, which can increase the risk of suicide. However, the current assessment tools cannot combine multiple risk factors to predict the risk probability of depression in patients.

DESIGN

A cross-sectional study.

METHODS

The clinical data from 297 patients with lung cancer in China were collected and analysed in this cross-sectional study. The clinical prediction model was constructed according to the results of the Chi-square test and the logistic regression analysis, evaluated by discrimination, calibration, and decision curve analysis, and visualised by a nomogram. This study was reported using the TRIPOD checklist.

RESULTS

130 patients with lung cancer had depressive symptoms with a prevalence of 43.77%. A visual prediction model was constructed based on age, disease duration, exercise, stigma, and resilience. This model showed good discrimination at an AUC of 0.842. Calibration curve analysis indicated a good agreement between experimental and predicted values, and the decision curve analysis showed a high clinical utility.

CONCLUSIONS

The visual prediction model developed in this study has excellent performance, which can accurately predict the occurrence of depression in patients with lung cancer at an early stage and assist the medical staff in taking targeted preventative measures.

RELEVANCE TO CLINICAL PRACTICE

The visual, non-invasive, and simple nomogram can help clinical medical staff to calculate the risk probability of depression among patients with lung cancer, formulate personalised preventive care measures for high-risk groups as soon as possible, and improve the quality of life of patients.

Prevalence of depression and associated factors among adult cancer patients receiving chemotherapy during the era of COVID-19 in Ethiopia. Hospital-based cross-sectional study

Background

Depression is a major public health problem among cancer patients undergoing chemotherapy. It compromises patient outcomes, resulting in higher rates of mortality. Currently, there are little data on the prevalence of depression in Sub-Sharan countries. Therefore, the current study was done to assess the prevalence of depression among adult cancer patients and its associated factors in Ethiopia.

Method

An institutional based cross-sectional study was conducted among 420 adult cancer patients from 1^st March to April 30, 2021. Systematic random sampling technique was used to recruit participants. Depression was assessed using the Patient Health Questionnaire-9. The collected data were coded and entered into Epi-data version 4.2 and exported to SPSS version 25 for analysis. Bivariate binary logistic regression was performed to select factors that will be included in multivariate analysis, and variables with a p-value < 0.05 were included in multivariate analysis. In multivariate analysis, odds ratios and their 95% confidence intervals were computed and variables with p-value < 0.05 were considered to declare a significant association.

Results

In this study, the prevalence of depression was 33.1% (95% CI = 0.2858, 0.3761). Minimal symptoms of depression, minor depression, moderate depression, moderate severe depression, and severe depression were found to be 272 (64.8%), 9 (2.1%), 104 (24.8%), 28 (6.7%), and 7 (1.7%), respectively. Those cancer patients who had unemployed status, sacked from jobs, and had stage IV cancer were most likely to develop depression, whereas patients who completed primary education, colon, prostate and cervical cancer were less likely to have depression.

Conclusion

Depression is found to be a major public health concern for adult cancer patients in Ethiopia. To reduce the occurrence of depression among cancer patients, special attention is needed.

The Beneficial Effects of Physical Activity in Lung Cancer Prevention and/or Treatment

Lung cancer is the most lethal cancer: it has a significant incidence and low survival rates. Lifestyle has an important influence on cancer onset and its progression, indeed environmental factors and smoke are involved in cancer establishment, and in lung cancer. Physical activity is a determinant in inhibiting or slowing lung cancer. Certainly, the inflammation is a major factor responsible for lung cancer establishment. In this scenario, regular physical activity can induce anti-inflammatory effects, reducing ROS production and stimulating immune cell system activity. On lung function, physical activity improves lung muscle strength, FEV1 and forced vital capacity. In lung cancer patients, it reduces dyspnea, fatigue and pain. Data in the literature has shown the effects of physical activity both in in vivo and in vitro studies, reporting that its anti-inflammatory action is determinant in the onset of human diseases such as lung cancer. It has a beneficial effect not only in the prevention of lung cancer, but also on treatment and prognosis. For these reasons, it is retained as an adjuvant in lung cancer treatment both for the administration and prognosis of this type of cancer. The purpose of this review is to analyze the role of physical activity in lung cancer and to recommend regular physical activity and lifestyle changes to prevent or treat this pathology.

Implementation and Effectiveness of a Veterans Affairs-Based Comprehensive Lung Cancer Survivorship Program

PURPOSE

Few programs exist to address persistent impairment in functional status, quality of life, and mental health in lung cancer survivors. We aimed to determine whether a 12-wk multimodal survivorship program imparts clinical benefit.

METHODS

Any patient at the Durham Veterans Affairs Medical Center with lung cancer and a Karnofsky score of ≥60 could participate. Chronic obstructive pulmonary disease medications were optimized at the enrollment visit. Participants with a Hospital Anxiety and Depression Scale (HADS) score of >8 were offered pharmacotherapy and mental health referral. Participants did home-based exercise with a goal of 1 hr/d, 5 d/wk. They were called weekly to assess exercise progress and review depression/anxiety symptoms. Participants were offered pharmacotherapy for smoking cessation.

RESULTS

Twenty-three (50%) of the first 46 enrollees completed the full 12-wk program. Paired changes from enrollment to completion (mean ± SD) were observed in 6-min walk test (73.6 ± 96.9 m, P = .002), BODE (Body mass index, airflow Obstruction, Dyspnea, and Exercise) index (-1.45 ± 1.64 points, P < .001), Duke Activity Status Index (3.84 ± 7.12 points, P = .02), Fried Frailty Index (-0.588 ± 0.939 points, P = .02), modified Medical Research Council dyspnea scale (-0.619 ± 1.284 points, P = .04), Functional Assessment of Cancer Therapy-Lung Emotional subscale score (1.52 ± 2.96 points, P = .03), HADS total score (-2.63 ± 4.34 points, P = .02), and HADS Anxiety subscale score (-1.47 ± 2.29 points, P = .01).

CONCLUSIONS

A comprehensive Lung Cancer Survivorship Program provides clinically meaningful improvements in functional status, quality of life, and mental health.

Feasibility and Impact of Adapted Physical Activity (APA) in Cancer Outpatients Beginning Medical Anti-Tumoral Treatment: The UMA-CHAPA Study

Simple Summary

Physical activity may reduce the risk of overall cancer incidence and improve survival in cancer patients. The beneficial effects of physical activity are also described in cancer survivors but remains poorly known during systemic cancer treatment. Therefore, we studied the feasibility of an adapted physical activity (APA) program in cancer outpatients beginning a medical anti-tumoral treatment for a digestive, lung, hematological, or dermatological cancer. We also studied the impact of APA on fatigue, anxiety, depression, and handgrip strength.

Abstract

Adapted physical activity (APA) improves quality of life and cancer outcomes. The aim of this study was to assess the feasibility of an APA program in outpatients beginning medical anticancer treatment. The secondary objective was to assess the impact of APA on fatigue, anxiety, depression, and handgrip strength (HGS). This prospective study was conducted between January and July 2017. Among 226 patients beginning treatment in the unit for a digestive, lung, hematological, or dermatological cancer, 163 were included. Adherence to the APA program was defined as more than or equal to one one-hour session per week for 3 months. The first evaluation was conducted at 3 months (M3), and the second evaluation at 6 months (M6). A total of 163 patients were included (mean age 62.5 ± 14.3); 139 (85.3%) agreed to follow the APA program. At M3, 106 of them were evaluated, of which 86 (81.1%) declared that they had followed the program. Improvement in anxiety was observed at M3 (−1.0 ± 3.2; p = 0.002) but there was no significant change in fatigue or depression. HGS decreased significantly (−1.2 ± 5.5; p = 0.04). The APA program was feasible in cancer outpatients beginning medical anticancer treatment. APA should be part of standard support care.

Impact of physical exercise in advanced-stage cancer patients: Systematic review and meta-analysis

Health professionals predict that the number of people who will suffer and die from oncological diseases will continue to increase. It is vitally important to provide comprehensive care to these patients and prescribe physical exercise programs as adjuvant therapy. The objective of this systematic review was to determine the impact of physical exercise on advanced‐stage cancer patients. A literature search was performed in eight different databases. This search focused on randomized controlled trials (RCTs) published during the last 10 years. To assess the methodological quality of the sample of 15 RCTs finally obtained, the PEDro scale was used. Aerobic and strength training methods were used. The combination of both aerobic and strength training methods was the most frequently reported. Likewise, different physical and psychological variables were recorded, from which improvements were seen in fatigue, independence, quality of life and sleep, among others. The participation in physical exercise programs by advanced‐stage cancer patients has a positive impact on health. Providing these programs serves as adjuvant therapy, facilitating the comprehensive care of patients. Similarly, aerobic, strength or mixed training programs increase the muscle mass of patients and therefore reduce hypotonia, the main side effect during the advanced‐stages of cancer.

Effect of acute aerobic exercise before immunotherapy and chemotherapy infusion in patients with metastatic non-small-cell lung cancer: protocol for the ERICA feasibility trial

INTRODUCTION

Patients with metastatic non-small cell lung cancer (mNSCLC) suffer from numerous symptoms linked to disease and treatment which may further impair the patient's overall condition. In addition to its benefits on quality of life and fatigue, physical exercise may improve treatment response, notably due to its known effects on the immune system. The ERICA study is designed to assess the feasibility of a supervised acute physical exercise therapy realised immediately prior immune-chemotherapy infusion in patients with mNSCLC. Secondary objectives will examine the effects of acute exercise combined with an unsupervised home-walking programme on clinical, physical, psychosocial and biological parameters.

METHODS AND ANALYSIS

ERICA is a prospective, monocentric, randomised controlled, open-label feasibility study conducted at the Centre Léon Bérard Comprehensive Cancer Center (France). Thirty patients newly diagnosed with mNSCLC will be randomised (2:1 ratio) to the 'exercise' or the 'control' group. At baseline and during the last treatment cycle, participants in both groups will receive Physical Activity recommendations, and two nutritional assessments. In the exercise group, participants will receive a 3-month programme consisting of a supervised acute physical exercise session prior to immune-chemotherapy infusion, and an unsupervised home-based walking programme with an activity tracker. The acute exercise consists of 35 min interval training at submaximal intensity scheduled to terminate 15 min prior to infusion. Clinical, physical, biological and psychosocial parameters will be assessed at baseline, 3 and 6 months after inclusion. Biological measures will include immune, inflammatory, metabolic, oxidative stress biomarkers and molecular profiling.

ETHICS AND DISSEMINATION

The study protocol was approved by the French ethics committee (Comité de protection des personnes Ile de France II, N°ID-RCB 20.09.04.65226, 8 December 2020). The study is registered on ClinicalTrials.gov (NCT number:NCT04676009) and is at the pre-results stage. All participants will sign an informed consent form. The findings will be disseminated in peer-reviewed journals and academic conferences.

High Intensity Aerobic exercise training and Immune cell Mobilization in patients with lung cancer (HI AIM)—a randomized controlled trial

Background

The increasing role of exercise training in cancer care is built on evidence that exercise can reduce side effects of treatment, improve physical functioning and quality of life. We and others have shown in mouse tumor models, that exercise leads to an adrenalin-mediated increased influx of T and NK cells into the tumor, altering the tumor microenvironment (TME) and leading to reduced tumor growth. These data suggest that exercise could improve immune responses against cancer cells by increase immune cell infiltration to the tumor and potentially having an impact on disease progression. Additionally, there are data to suggest that infiltration of T and NK cells into the TME is correlates with response to immune checkpoint inhibitors in patients. We have therefore initiated the clinical trial HI AIM, to investigate if high intensity exercise can mobilize and increase infiltration of immune cells in the TME in patients with lung cancer.

Methods

HI AIM (NCT04263467) is a randomized controlled trial (70 patients, 1:1) for patients with non-small cell lung cancer. Patients in the treatment arm, receive an exercise-intervention consisting of supervised and group-based exercise training, comprising primarily intermediate to high intensity interval training three times per week over 6 weeks. All patients will also receive standard oncological treatments; checkpoint inhibitors, checkpoint inhibitors combined with chemotherapy or oncological surveillance. Blood samples and biopsies (ultrasound guided), harvested before, during and after the 6-week training program, will form basis for immunological measurements of an array of immune cells and markers. Primary outcome is circulating NK cells. Secondary outcome is other circulating immune cells, infiltration of immune cells in tumor, inflammatory markers, aerobic capacity measured by VO₂ max test, physical activity levels and quality of life measured by questionnaires, and clinical outcomes.

Discussion

To our knowledge, HI AIM is the first project to combine supervised and monitored exercise in patients with lung cancer, with rigorous analyses of immune and cancer cell markers over the course of the trial. Data from the trial can potentially support exercise as a tool to mobilize cells of the immune system, which in turn could potentiate the effect of immunotherapy.

Trial registration

The study was prospectively registered at ClinicalTrials.gov on February 10^th 2020, ID: NCT04263467. https://clinicaltrials.gov/ct2/show/NCT04263467

Effects and tolerability of exercise therapy modality on cardiorespiratory fitness in lung cancer: a randomized controlled trial

BACKGROUND

Poor cardiorespiratory fitness (CRF) is a cardinal feature of post-treatment primary lung cancer. The most effective exercise therapy regimen to improve CRF has not been determined.

METHODS

In this parallel-group factorial randomized controlled trial, lung cancer survivors with poor CRF (below age-sex sedentary values) were randomly allocated to receive 48 consecutive supervised sessions thrice weekly of (i) aerobic training (AT)-cycle ergometry at 55% to >95% of peak oxygen consumption (VO₂ peak); (ii) resistance training (RT)-lower and upper extremity exercises at 50-85% of maximal strength; (iii) combination training (CT)-AT plus RT; or (iv) stretching attention control (AC) for 16 weeks. The primary endpoint was change in CRF (VO₂ peak, mL O₂ ·kg^-1 ·min^-1 ). Secondary endpoints were body composition, muscle strength, patient-reported outcomes, tolerability (relative dose intensity of exercise), and safety. Analysis of covariance determined change in primary and secondary endpoints from baseline to post-intervention (Week 17) with adjustment for baseline values of the endpoint and other relevant clinical covariates.

RESULTS

Ninety patients (65 ± 9 years; 66% female) were randomized (AT, n = 24; RT, n = 23; CT, n = 20; and AC, n = 23) of the planned n = 160. No serious adverse events were observed. For the overall cohort, the lost-to-follow-up rate was 10%. Mean attendance was ≥75% in all groups. In intention-to-treat analysis, VO₂ peak increased 1.1 mL O₂ ·kg^-1 ·min^-1 [95% confidence interval (CI): 0.0, 2.2, P = 0.04] and 1.4 mL O₂ ·kg^-1 ·min^-1 (95% CI: 0.2, 2.5, P = 0.02) in AT and CT, respectively, compared with AC. There was no difference in VO₂ peak change between RT and AC (-0.1 mL O₂ ·kg^-1 ·min^-1 , 95% CI: -1.2, 1.0, P = 0.88). Favourable improvements in maximal strength and body composition were observed in RT and CT groups compared with AT and AC groups (Ps < 0.05). No between-group changes were observed for any patient-reported outcomes. Relative dose intensity of exercise was lower in RT and CT compared with AT (Ps < 0.05).

CONCLUSIONS

In the context of a smaller than planned sample size, AT and CT significantly improved VO₂ peak in lung cancer survivors; however, the tolerability-to-benefit ratio was superior for AT and hence may be the preferred modality to target impaired CRF in post-treatment lung cancer survivors.

Prehabilitation exercise therapy for cancer: A systematic review and meta-analysis

OBJECTIVE

The purpose of this study was to determine the impact of prehabilitation exercise intervention with respect to (1) acceptability, feasibility, and safety; and (2) physical function, measured by 6-minute-walk test (6MWT).

DATA SOURCES

PRISMA guidelines were used to systematically search PubMed, Embase, and CINAHL databases evaluating prehabilitation exercise interventions.

STUDY SELECTION

The inclusion criteria were studies investigating patients who underwent surgery for their cancer and underwent prehabilitation exercise.

DATA EXTRACTION AND SYNTHESIS

Guidelines were applied by independent extraction by multiple observers. Data were pooled using a random-effects model.

MAIN OUTCOME(S) AND MEASURE(S)

Acceptability, feasibility, and safety rates were calculated. 6MWT (maximum distance a person can walk at their own pace on a hard, flat surface, measured in meters, with longer distance indicative of better performance status) was compared using two arms using the DerSimonian and Laird method.

RESULTS

Objective 1. Across 21 studies included in this review, 1564 patients were enrolled, 1371 (87.7%) accepted the trial; of 1371, 1230 (89.7% feasibility) completed the intervention. There was no grade 3+ toxicities. Objective 2. Meta-analysis of five studies demonstrated a statistically significant decrease in 6MWT distance postoperatively in the control group (mean difference = +27.9 m; 95% confidence interval (CI): 9.3; 46.6) and a significant improvement postoperatively in the prehabilitation group (mean difference = -24.1 m; 95% CI: -45.7; -2.6). Meta-analysis demonstrated improvements in 6MWT distance 4-8 weeks postoperatively in the prehabilitation group compared to the control group (mean difference = -58.0 m, 95% CI: -92.8; -23.3).

CONCLUSIONS AND RELEVANCE

Prehabilitation exercise for cancer patients undergoing surgery was found to be safe, acceptable, and feasible with a statistically significant improvement in the 6MWT, indicating that prehabilitation can improve postoperative functional capacity.

Food, Nutrition, Physical Activity and Microbiota: Which Impact on Lung Cancer?

Lung cancer still represents the leading cause of cancer-related death, globally. Likewise, malnutrition and inactivity represent a major risk for loss of functional pulmonary capacities influencing overall lung cancer severity. Therefore, the adhesion to an appropriate health lifestyle is crucial in the management of lung cancer patients despite the subtype of cancer. This review aims to summarize the available knowledge about dietary approaches as well as physical activity as the major factors that decrease the risk towards lung cancer, and improve the response to therapies. We discuss the most significant dietary schemes positively associated to body composition and prognosis of lung cancer and the main molecular processes regulated by specific diet schemes, functional foods and physical activity, i.e., inflammation and oxidative stress. Finally, we report evidence demonstrating that dysbiosis of lung and/or gut microbiome, as well as their interconnection (the gut–lung axis), are strictly related to dietary patterns and regular physical activity playing a key role in lung cancer formation and progression, opening to the avenue of modulating the microbiome as coadjuvant therapy. Altogether, the evidence reported in this review highlights the necessity to consider non-pharmacological interventions (nutrition and physical activity) as effective adjunctive strategies in the management of lung cancer.

The Association of Sources of Support, Types of Support and Satisfaction with Support Received on Perceived Stress and Quality of Life of Cancer Patients

INTRODUCTION

The aim of the present study is to carry out a multidimensional analysis of the relationship of social support with quality of life and the stress perceived by cancer patients.

METHODS

The participants were 200 patients with cancer. Data was gathered on sociodemographic characteristics, health, quality of life, social support and perceived stress.

RESULTS

Frequency of and satisfaction with different sources and types of support are related positively with improvement of quality of life and negatively with perceived stress. The emotional support from the partner and the emotional and informational support from the family are significant predictors of quality of life. Emotional support from the family reduces patients' perceived stress. Satisfaction with emotional support from the partner and with the informational support from friends and family increases quality of life. Satisfaction with emotional support from the family and with informational support from friends decreases patients' perceived stress. Instrumental support and support provided by health professionals are not good predictors of quality of life and perceived stress. Satisfaction with the support received is more significantly related with quality of life and stress than the frequency with which the sources provide support.

CONCLUSIONS

These results have important practical implications to improve cancer patients' quality of life and reduce their perceived stress through social support. Designing intervention strategies to improve satisfaction with the support provided to patients by their closest networks results in a global benefit for the patient's quality of life.

Plasticity in bilateral hippocampi after a 3-month physical activity programme in lung cancer patients

BACKGROUND AND PURPOSE

Cancer treatments have deleterious effects on both brain structure and the cognition of lung cancer patients. Physical activity (PA) has beneficial effects on the cognition of healthy adults by eliciting brain plasticity, especially on the medial temporal lobe (hippocampus). Therefore, the aim was to study the neuroprotective effects of a 3-month PA programme (PAP) on the brain structure and cognitive performance of lung cancer patients.

METHODS

Twelve patients (seven non-small-cell lung cancer [NSCLC] patients following chemotherapy, five small-cell lung cancer [SCLC] patients following chemotherapy and prophylactic cranial irradiation) agreed to complete the PAP and underwent baseline and 3-month (post-PAP) brain magnetic resonance imaging and neuropsychological evaluations (PAP group). Twelve lung cancer patients (seven NSCLC, five SCLC; non-PAP group) and 12 healthy sex-, age- and education-matched controls were recruited and completed two evaluations separated by the same amount of time. A region of interest voxel-based morphometry analysis focused on bilateral hippocampi was performed.

RESULTS

Physical activity programme patients presented greater grey matter volume (GMV) across time in both hippocampi. Moreover, it was observed that SCLC patients in both the PAP and non-PAP groups presented a time-dependent GMV loss in bilateral hippocampi that was not significant in NSCLC patients. Importantly, the PA intervention decreased the magnitude of that GMV loss, becoming thus especially beneficial at the brain structural level for SCLC patients.

CONCLUSIONS

Our study demonstrates, using a neuroimaging approach for the first time, that PA is able to stop the deleterious effects of systemic chemotherapy and brain radiation on brain structures of the lung cancer population, especially in SCLC patients.

Measurements of Older Adults' Physical Competence under the Concept of Physical Literacy: A Scoping Review

Physical literacy, especially in the fields of physical education and public health, has been gaining global interest in recent years. Applying an appropriate method to measure physical competence under the concept of physical literacy for older adults aligns with the goal of healthy aging. In this scoping review, we reflected on previous empirical studies regarding the measurements of physical competence among older adults holistically and systematically to identify and analyze gaps in the topic of “physical literacy” among older adults as a precursor to a systematic review. We searched five databases using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) for Protocols guidelines: (1) SPORTDiscus; (2) PubMed; (3) Scopus; (4) ScienceDirect; and (5) Web of Science. There were 29 studies included in our thematic analysis. Through our review, we found that 73% of the mean age of the participants comprised older baby boomers who were from 65–74 years old as aging continues. Therefore, more effort should be made in developing physical literacy for older adults with the goal of health promotion. Our results showed that most studies adopted both self-reported and objective measures, in which objective measures were widely embraced by scholars in the measurement, while self-reported measures were encouraged to be included in the assessment as well. Using assessment tools to measure a combination of actual physical competence and perceived physical competence is recommended in the measurement of physical competence, especially in older adults. In addition, other elements of physical literacy should be taken into account when measuring physical competency in older adults. For future implementation, when framing the model to chart physical literacy for older adults, it is important to review the definition again and adopt a holistic measurement system including every aspect of physical literacy.

Supervised Physical Rehabilitation in the Treatment of Patients with Advanced Cancer: a Systematic Review and Meta-analysis

BACKGROUND

As the survival rate of cancer patients increases, the clinical importance of rehabilitation provided by healthcare professionals also increases. However, the evidence supporting the relevance of rehabilitation programs is insufficient. This study aimed to review the literature on effectiveness in physical function, quality of life (QOL) or fatigue of supervised physical rehabilitation in patients with advanced cancer.

METHODS

A systematic review and meta-analysis was conducted following the Cochrane guidelines. We narratively described the results when meta-analysis was not applicable or appropriate. Literature databases including Ovid-MEDLINE, Ovid-EMBASE, and the Cochrane Library, as well as several Korean domestic databases, were searched up to June 2017 for studies that investigated the effectiveness of supervised physical rehabilitation programs on physical function, QOL or fatigue in patients with advanced cancer. The quality of the selected studies was evaluated independently by paired reviewers.

RESULTS

Eleven studies with 922 participants were finally selected among 2,459 articles. The meta-analysis revealed that after physical exercise, the physical activity level and strength of patients with advanced cancer increased significantly. The QOL showed a statistically significant improvement after physical rehabilitation according to the European Organization for Research and Treatment of Cancer version C30. Though some of measurements about cardiovascular endurance or strength in several studies were not able to be synthesized, each study reported that they were significantly improved after receiving rehabilitation.

CONCLUSION

Supervised physical rehabilitation for patients with advanced cancer is effective in improving physical activity, strength, and QOL. However, more trials are needed to prove the effectiveness of supervised exercise and to strengthen the evidence.

Feasibility of a multimodal intervention on malnutrition in patients with lung cancer during primary anti-neoplastic treatment

BACKGROUND

Wasting of body mass and skeletal muscle frequently develops in patients with cancer and is associated with impaired functional ability and poor clinical outcome and quality of life. This study aimed to evaluate the feasibility and explore the effect of a multimodal intervention targeting nutritional status in patients with non-small cell lung cancer receiving primary anti-neoplastic treatment. Additionally, predictive and prognostic factors of gaining skeletal muscle were explored.

METHODS

This was a single-centre multimodal intervention trial using a historical control group. The multimodal intervention involved fish oil intake (2 g of eicosapentaenoic acid or docosahexaenoic acid daily), regular dietary counselling and unsupervised physical exercise twice weekly during the first three cycles of primary anti-neoplastic treatment. Feasibility was assessed through recruitment rate, completion rate and compliance rate with the intervention. Differences in skeletal muscle, body weight, and physical function between the intervention and historical control groups were analysed. Factors contributing to increased skeletal muscle were explored using univariate and multivariate ordinal logistic regression analyses.

RESULTS

The recruitment and completion rates were 0.48 (n = 59/123) and 0.80 (n = 46/59), respectively. The overall compliance rate with all five individual interventions was 0.60 (n = 28/47). The individual compliance rates were 0.81 (n = 38/47) with fish oil intake, 0.94 (n = 44/47) with energy intake, 0.98 (n = 46/47) with protein intake, 0.51 (n = 24/47) with resistance exercise and 0.57 (n = 27/47) with aerobic exercise. No mean differences in skeletal muscle, body weight, or physical function were found between the intervention and control groups. However, a larger proportion of patients in the intervention group gained skeletal muscle (p < 0.02). The identified contributing factors of muscle gain were weight gain (OR, 1.3; p = 0.01), adherence to treatment plan (OR, 4.6; p = 0.02), stable/partial response (OR, 3.3; p = 0.04) and compliance to the intervention (OR, 7.4; p = 0.01). Age, sex, tumour stage, performance status, treatment type and baseline cachexia did not predict muscle gain.

CONCLUSION

This three-dimensional intervention in patients with lung cancer undergoing primary anti-neoplastic treatment was feasible and increased the proportion of patients gaining skeletal muscle. Dietary counselling and fish oil use were useful strategies. The motivation for conducting unsupervised physical intervention was low. Clinical trials.gov identifier: NCT04161794.

Exercise training as part of lung cancer therapy

Exercise training is playing an increasing role in lung cancer care. Lung cancer is associated with significant burden to the individual and healthcare system. There is now substantial evidence that exercise training is safe, feasible and effective at improving several outcomes in people with lung cancer, especially in those with NSCLC. Exercise is beneficial across the lung cancer disease and treatment pathway, including in patients with early stage disease before and after surgery, and in patients with advanced disease. This review describes the impact of lung cancer and lung cancer treatment on patient health outcomes and summarizes the aims, safety, feasibility and effects of exercise training in the context of both early stage and advanced stage lung cancer. The paper also includes a discussion of current topical discussion areas including the use of exercise in people with bone metastases and the potential effect of exercise on suppression of tumour growth. Finally, seven clinical questions are included, which are a priority to be addressed by future research over the next decade as we strive to progress the field of lung cancer and improve patient outcomes.

Exercise Training in Patients With Non-Small Cell Lung Cancer During In-Hospital Chemotherapy Treatment: A RANDOMIZED CONTROLLED TRIAL

This study aimed to assess the impact of exercise training in patients with lung cancer on several outcomes compared to a control group. Results suggest that exercise programs in patients with lung cancer are a practical and beneficial intervention for enhancing mobility and physical fitness.

Purpose:

The aim of this study was to perform a randomized trial to assess the impact of exercise training in patients with non–small cell lung cancer during chemotherapy on several outcomes in comparison to a control group (CG).

Methods:

The exercise training group (ETG) consisted of 20 patients and the CG consisted of 10 patients. In the ETG, a 4-wk in-hospital exercise training program was performed in 2-wk cycles interspersed with consecutive rounds of chemotherapy with cytostatic drugs. The exercise training program was individualized and included warm-up, respiratory muscle exercise, training on a cycle ergometer or treadmill, and Nordic walking. CG participants were assessed before and after 6 wk of chemotherapy alone.

Results:

Comparing pre- and post-intervention values, the ETG demonstrated an increase in 6-min walk distance (486 ± 92 vs 531 ± 103 m, P = .01). In a battery of physical performance tests: Up and Go Test (6.3 ± 1.0 vs 6.0 ± 1.1 sec, P = .01); chair stand (13.3 ± 2.8 vs 14.3 ± 3.4 repetitions, P = .001); and arm curl (18.4 ± 3.1 vs 20.4 ± 3.5 repetitions, P = .001) all improved significantly. Spirometry values also improved: FEV₁ % predicted (76 ± 16 vs 84 ± 15, P = .01), FVC % predicted (87 ± 14 vs 95 ± 13, P = .01), and FEV₁/FVC (73 ± 13% vs 76 ± 12%, P = .04). The exercise training was well tolerated, without any adverse events due to exercise. There were no significant improvements in the CG.

Conclusions:

This study suggests that planned, individualized, and supervised exercise programs in patients with advanced lung cancer during chemotherapy are a practical and beneficial intervention for enhancing mobility and physical fitness.

Effects of an exercise intervention for patients with advanced inoperable lung cancer undergoing chemotherapy: A randomized clinical trial

OBJECTIVE

Exercise can improve treatment-related side effects, quality of life, and function in patients with various types of cancer; however, more evidence is needed for patients with advanced inoperable lung cancer.

MATERIAL AND METHODS

We randomized 218 patients with advanced inoperable lung cancer to a 12-week supervised, structured exercise training program (aerobic, strength, and relaxation training) twice weekly versus usual care. Primary outcome was change in maximal oxygen uptake (VO₂ peak). Secondary outcomes were muscle strength, functional capacity, forced expiratory volume in 1 s, health-related quality of life, anxiety, and depression.

RESULTS

There was no significant difference between the intervention and control groups in VO₂ peak. There was a significant improvement in muscle strength. There was also a significant difference between the two for social well-being (Functional Assessment of Cancer Therapy-Lung, FACT-L), anxiety, and depression.

CONCLUSION

There was a significant reduction in the level of anxiety and depression and a significant increase in all muscle strength outcomes in the intervention group compared to patients randomized to usual care. There was a significant difference between the groups for social well-being. The primary outcome did not show a significant improvement in VO₂ peak. Based on our results, future patients with advanced inoperable lung cancer should be considered for supervised exercise during the course of their disease.

Exercise experiences in patients with metastatic lung cancer: A qualitative approach

Background

Patients with metastatic lung cancer can have severe cancer-related symptoms and treatment-induced side effects. Exercise is beneficial for patients with metastatic lung cancer; however, little information is available on guiding patients how to perform exercise during hospitalization. The purpose of this qualitative study was to understand exercise experiences in patients with metastatic lung cancer.

Methods

Patients with metastatic lung cancer (n = 24) participated in face-to-face in-depth interviews at an inpatient ward of a medical center in central Taiwan. Interview transcripts were evaluated using narrative analysis to extract and validate themes.

Results

Three primary themes were identified: (1) modifying exercise to maximize physical functions; (2) living with symptoms and frustration, but still exercising; and (3) doing exercise to sustain hopes, inner power, and life. Secondary findings included: (1) adopting walking as their main form of exercise because of its convenience; and (2) among patients with severe symptoms, adjusting exercise towards shorter time durations and shorter distances, slower speeds, and higher frequencies.

Conclusions

The study found physically active lung cancer patients, although with metastatic condition, adjusted their exercise activities to balance disease and treatment-induced deteriorations and boost themselves to feel hope and fight for cancer. However, the results may not be applicable to physically inactive patients. Future research to explore experiences from those with even worse physical conditions and further helping them to take some mild exercise to enhance the positive side of cancer experiences are suggested.

Exercise effects on brain and behavior in healthy mice, Alzheimer's disease and Parkinson's disease model-A systematic review and meta-analysis

This systematic review and meta-analysis examines how exercise modifies brain and behavior in healthy mice, dementia (D) and Parkinson disease (PD) models. A search was performed on the Medline and Scopus electronic databases (2008-2019). Search terms were "mice", "brain", "treadmill", "exercise", "physical exercise". In the total, 430 were found but only 103 were included. Animals n = 1,172; exercised 4-8 weeks (Range 24 h to 32 weeks), 60 min/day (Range 8-120 min per day), and 10/12 m/min (Range 0.2 m/min to 36 m/min). Hippocampus, cerebral cortex, striatum and whole brain were more frequently investigated. Exercise improved learning and memory. Meta-analysis showed that exercise increased: cerebral BDNF in health (n = 150; z = 5.8, CI 3.43-12.05; p < 0.001 I2 = 94.3 %), D (n = 124; z = 4.18, CI = 2.22-9.12; p < 0.001; I2 = 93.7 %) and PD (n = 16 z = 4.26, CI 5.03-48.73 p < 0.001 I2 = 94.8 %). TrkB improved in health (n = 84 z = 5.49, CI 3.8-17.73 p < 0.001, I2 = 0.000) and PD (n = 22; z = 3.1, CI = 2.58-67.3, p < 0.002 I2 = 93.8 %). Neurogenesis increased in health (n = 68; z = 7.08, CI 5.65-21.25 p < 0.001; I2 17.58) and D model (n = 116; z = 4.18, CI 2.22-9.12 p < 0.001 I2 93.7 %). Exercise augmented amyloid clearance (n = 166; z = 7.51 CI = 4.86-14.85, p < 0.001 I2 = 58.72) and reduced amyloid plaques in D models (n = 49; z = 4.65, CI = 3.94-15.3 p < 0.001 I2 = 0.000). In conclusion, exercise improved brain and behavior, neurogenesis in healthy and dementia models, reduced toxicity and cerebral amyloid. Evidence regarding inflammation, oxidative stress and energy metabolism were scarce. Studies examining acute vs chronic exercise, extreme training and the durability of exercise benefit were rare. Vascular or glucose metabolism changes were seldom reported.

The impact of WeChat app-based education and rehabilitation program on anxiety, depression, quality of life, loss of follow-up and survival in non-small cell lung cancer patients who underwent surgical resection

PURPOSE

We aimed to explore whether WeChat app-based education and rehabilitation program (WERP) affected anxiety, depression, quality of life (QoL), loss of follow-up and survival profiles in non-small cell lung cancer (NSCLC) patients after undergoing surgical resection.

METHODS

200 NSCLC patients who underwent surgical resection were randomly allocated to WERP group or control group at a 1:1 ratio and underwent a 12-month interventional stage and 48-month non-interventional follow-up stage. Anxiety and depression were evaluated by Hospital Anxiety and Depression Scale (HADS), and QoL was assessed by European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (QLQ-C30). Loss of follow-up and survival data were also evaluated.

RESULTS

After the 12-month intervention (M12), HADS-anxiety score (5.00 ± 2.84 vs. 6.69 ± 4.01) and anxiety rate (19.0% vs. 41.0%) were lower in WERP group compared with control group; meanwhile, HADS-depression score (5.22 ± 2.77 vs. 6.55 ± 3.42) and depression rate (20.0% vs. 36.0%) were decreased in WERP group compared with the control group. Regarding QoL at M12, the QLQ-C30 global health status score (74.44 ± 12.06 vs. 70.26 ± 17.29) and functional score (77.15 ± 15.00 vs. 71.40 ± 17.02) were higher, while QLQ-C30 symptom score was similar (27.29 ± 11.72 vs. 27.86 ± 12.69) in WERP group compared with the control group. Besides, both the 12-month loss to follow-up (3.0% vs 10.0%) and 60-month loss to follow-up (10.0% vs 20.0%) were less in WERP group than the control group. However, limited survival benefit of WERP was observed compared with the control group.

CONCLUSIONS

WERP is an effective way to improve well-being and quality of life in NSCLC patients after undergoing surgical resection.

Physical Activity and Exercise in Lung Cancer Care: Will Promises Be Fulfilled?

Lung cancer remains the leading cause of cancer‐related death worldwide. Affected patients frequently experience debilitating disease‐related symptoms, including dyspnea, cough, fatigue, anxiety, depression, insomnia, and pain, despite the progresses achieved in term of treatment efficacy.

Physical activity and exercise are nonpharmacological interventions that have been shown to improve fatigue, quality of life, cardiorespiratory fitness, pulmonary function, muscle mass and strength, and psychological status in patients with lung cancer. Moreover, physical fitness levels, especially cardiorespiratory endurance and muscular strength, are demonstrated to be independent predictors of survival. Nevertheless, patients with lung cancer frequently present insufficient levels of physical activity and exercise, and these may contribute to quality of life impairment, reduction in functional capacity with skeletal muscle atrophy or weakness, and worsening of symptoms, particularly dyspnea.

The molecular bases underlying the potential impact of exercise on the fitness and treatment outcome of patients with lung cancer are still elusive. Counteracting specific cancer cells’ acquired capabilities (hallmarks of cancer), together with preventing treatment‐induced adverse events, represent main candidate mechanisms.

To date, the potential impact of physical activity and exercise in lung cancer remains to be fully appreciated, and no specific exercise guidelines for patients with lung cancer are available. In this article, we perform an in‐depth review of the evidence supporting physical activity and exercise in lung cancer and suggest that integrating this kind of intervention within the framework of a global, multidimensional approach, taking into account also nutritional and psychological aspects, might be the most effective strategy.

Implications for Practice

Although growing evidence supports the safety and efficacy of exercise in lung cancer, both after surgery and during and after medical treatments, most patients are insufficiently active or sedentary. Engaging in exercise programs is particularly arduous for patients with lung cancer, mainly because of a series of physical and psychosocial disease‐related barriers (including the smoking stigma). A continuous collaboration among oncologists and cancer exercise specialists is urgently needed in order to develop tailored programs based on patients’ needs, preferences, and physical and psychological status. In this regard, benefit of exercise appears to be potentially enhanced when administered as a multidimensional, comprehensive approach to patients’ well‐being.

The potential effect of physical activity in lung cancer is not fully understood, and no specific exercise guidelines for lung cancer patients are available. This article reviews the evidence supporting physical activity and exercise in lung cancer and suggests that this type of intervention, along with considerations for the nutritional and psychological aspects of such an intervention, might be the most effective strategy.

Influence of Tai Chi on Self-Efficacy, Quality of Life, and Fatigue Among Patients With Cancer Receiving Chemotherapy: A Pilot Study Brief

Purpose: While exercise is an effective intervention used to minimize side effects associated with chemotherapy, tai chi (TC) exercise for persons actively receiving chemotherapy remains understudied. The purposes of this study were to (a) evaluate the effects of TC on self-efficacy, quality of life (QOL), and cancer-related fatigue (CRF) and (b) understand the experience and perceived benefits of patients taking chemotherapy involved in a TC program. Design: An explanatory sequential mixed methods study with a dominant qualitative strand was used to explore the differences between an intervention group participating in TC ( n = 3) and a nonexercising, wait-listed comparison group ( n = 3). Method: Following 8-weeks of TC classes, a focus group was conducted with the intervention group. Pretest/posttest scores for CRF, self-efficacy, and QOL were analyzed using t tests to compare the means between and within groups. Thematic analysis was used to interpret transcripts. Quantitative and qualitative results were compared to determine congruence between findings. Findings: Qualitative findings revealed increased mind/body strength. Quantitative scores trended toward improved CRF, self-efficacy, and QOL. Findings from the two strands supported one another. Conclusions: Tai chi is an effective and feasible exercise for individuals with cancer receiving chemotherapy. This mind–body exercise appears to provide benefits beyond improved physical functioning.

Pre-radiotherapy daily exercise training in non-small cell lung cancer: A feasibility study

Aim

To examine the feasibility of an individual, supervised, structured moderate-to-high intensity cycle ergometer exercise training immediately before radiotherapy in patients undergoing concomitant chemoradiotherapy for locally advanced non-small cell lung cancer (NSCLC).

Background

Lung cancer is the most common form of cancer. Despite significant advancements in therapy and supportive care it is still the leading cause of cancer-related death worldwide.

Materials and methods

Randomized controlled study design; patients with NSCLC receiving concomitant chemoradiotherapy were recruited and randomly assigned to either the exercise (EXE) or the control (CON) group. Exercise training consisted of 20 min moderate-to-high intensity aerobic interval training 5 times per week (Mon-Fri) prior to radiotherapy. Secondary outcomes were assessed at baseline and after 7 weeks: peak oxygen consumption (VO_2peak), functional capacity (6MWD), pulmonary function (FEV1), psychosocial parameters (quality of life (FACT-L), anxiety and depression (HADS)) and cancer-related side effects (reported daily).

Results

Fifteen patients were included. All patients completed a baseline test, while 13 patients were eligible for a posttest. The recruiting rate was 44.1% and the overall attendance rate to exercise was 90.0% with an adherence rate to full exercise participation of 88.1%. No adverse events or any unexpected reactions were observed during the exercise sessions. No significant differences were observed within or between groups from baseline to post intervention in any of the secondary outcomes.

Conclusion

This study demonstrated 'proof of principle' that daily moderate-to-high intensity cycle ergometer exercise was feasible, safe and well tolerated among newly diagnosed patients with locally advanced NSCLC undergoing concomitant chemoradiotherapy. Larger randomized controlled trials are warranted.

Multidisciplinary home-based rehabilitation in inoperable lung cancer: a randomised controlled trial

BACKGROUND

Lung cancer is associated with poor health-related quality of life (HRQoL) and high symptom burden. This trial aimed to assess the efficacy of home-based rehabilitation versus usual care in inoperable lung cancer.

METHODS

A parallel-group, assessor-blinded, allocation-concealed, randomised controlled trial. Eligible participants were allocated (1:1) to usual care (UC) plus 8 weeks of aerobic and resistance exercise with behaviour change strategies and symptom support (intervention group (IG)) or UC alone. Assessments occurred at baseline, 9 weeks and 6 months. The primary outcome, change in between-group 6 min walk distance (6MWD), was analysed using intention-to-treat (ITT). Subsequent analyses involved modified ITT (mITT) and included participants with at least one follow-up outcome measure. Secondary outcomes included HRQoL and symptoms.

RESULTS

Ninety-two participants were recruited. Characteristics of participants (UC=47, IG=45): mean (SD) age 64 (12) years; men 55%; disease stage n (%) III=35 (38) and IV=48 (52); radical treatment 46%. There were no significant between-group differences for the 6MWD (n=92) at 9 weeks (p=0.308) or 6 months (p=0.979). The mITT analyses of 6MWD between-group differences were again non-significant (mean difference (95% CI): 9 weeks: -25.4 m (-64.0 to 13.3), p=0.198 and 6 months: 41.3 m (-26.7 to 109.4), p=0.232). Significant 6-month differences, favouring the IG, were found for HRQoL (Functional Assessment of Cancer Therapy-Lung: 13.0 (3.9 to 22.1), p=0.005) and symptom severity (MD Anderson Symptom Inventory-Lung Cancer: -2.2 (-3.6 to -0.9), p=0.001).

CONCLUSIONS

Home-based rehabilitation did not improve functional exercise capacity but there were improvements in patient-reported exploratory secondary outcomes measures observed at 6 months.

New lung cancer treatments (immunotherapy and targeted therapies) and their associations with depression and other psychological side effects as compared to chemotherapy

OBJECTIVE

Lung cancer carries a high prevalence of distress, anxiety and depression. New treatments, targeted therapy and immunotherapy have changed the disease course for subsets of patients and confer longer survival, but their psychological associations and possible mechanisms (e.g., inflammation and physical symptoms) are not well described.

METHOD

Patients with metastatic lung cancer undergoing systemic treatment (n = 109) were evaluated for distress, self-endorsed problems using the Distress Thermometer and Problem List, and depression and anxiety using the Hospital Anxiety and Depression Scale. Demography, cancer-related information, and inflammation were evaluated for their associations with chemotherapy, targeted therapy, and immunotherapy. Inflammation was measured by C-reactive protein, albumin, and neutrophil to lymphocyte ratio.

RESULTS

Chemotherapies were given most often followed by immunotherapy and targeted therapies. Depression and anxiety were endorsed by 23.9%, respectively, and 41.1% had significant distress. Chemotherapy was associated with depression (p = .006) and inflammation (p < .001). Physical symptoms were the same among treatment types. Targeted therapy and immunotherapy predicted for less depression (p = .04, p = .04 respectively) than chemotherapy when controlling for age, sex, and performance status however these predictors where not significant when controlled for inflammation.

CONCLUSION

New immunotherapy and targeted therapies are associated with less depression and inflammation among patients who are living longer while their physical symptoms are the same.

Engaging the older cancer patient; Patient Activation through Counseling, Exercise and Mobilization - Pancreatic, Biliary tract and Lung cancer (PACE-Mobil-PBL) - study protocol of a randomized controlled trial

Background

Several intervention studies have demonstrated that exercise training has beneficial effects among cancer patients. However, older cancer patients are underrepresented in clinical trials, and only few exercise-based studies have focused specifically on older patients with cancer. In particular, research investigating the effects of exercise training among older patients with advanced cancer is lacking. The purpose of the current study is to investigate the effect of a 12-week multimodal and exercise-based intervention among older patients (≥65 years) with advanced pancreatic, biliary tract or lung cancer, who are treated with first-line palliative chemotherapy, immunotherapy or targeted therapy.

Methods

PACE-Mobil-PBL is a two-armed randomized controlled trial. Participants will be randomized 1:1 to an intervention group (N = 50) or a control group (N = 50). Participants in the intervention group will receive standard oncological treatment and a 12-week multimodal intervention, comprised of: (I) supervised exercise training, twice weekly in the hospital setting, (II) home-based walking with step counts and goal-setting, (III) supportive and motivational nurse-led counseling, and (IV) protein supplement after each supervised training session. Participants in the control group will receive standard oncological treatment. The primary outcome is physical function measured by the 30-s chair stand test. Secondary outcomes include measures of feasibility, activity level, physical capacity and strength, symptom burden, quality of life, toxicity to treatment, dose reductions, inflammatory biomarkers, body weight and composition, hospitalizations and survival. Assessments will be conducted at baseline, and after 6, 12 and 16 weeks.

Discussion

The current study is one of the first to investigate the effect of an exercise-based intervention specifically targeting older patients with advanced cancer. PACE-Mobil-PBL supports the development of health promoting guidelines for older patients with cancer, and the study results will provide new and valuable knowledge in this understudied field.

Trial registration

The study was prospectively registered at ClinicalTrials.gov on January 26, 2018 (ID: NCT03411200).

Frailty assessment predicts toxicity during first cycle chemotherapy for advanced lung cancer regardless of chronologic age

BACKGROUND

Improved assessment strategies are needed to individualize treatment for adults of all ages receiving palliative chemotherapy for non-small cell lung cancer (NSCLC). Our aim was to evaluate the utility of the Fried Frailty Index (FFI) and a cancer-specific geriatric assessment (GA) to predict chemotherapy toxicity and overall survival (OS).

METHODS

We conducted a multi-site pilot study of 50 patients with newly diagnosed advanced NSCLC, age ≥ 18 years. All participants received carboplatin AUC 6, paclitaxel 200 mg/m² every 3 weeks. FFI and the GA were administered prior to chemotherapy. A GA toxicity risk score was calculated. Grade 3-5 toxicity was assessed during 1st two cycles of chemotherapy. OS was measured from chemotherapy initiation. Logistic regression and Cox proportional hazards models were fit to estimate the association between baseline characteristics and toxicity and OS respectively.

RESULTS

Among 50 participants, 48 received chemotherapy and were evaluable. The mean age was 68.5 y (range 42-86), 79% male, 85% KPS ≥80. The median OS was 8 months. Many (27%) met FFI criteria for frailty with ≥3 impairments. Impairments detected by the GA were common. In multivariable analyses both FFI ≥ 3 and GA toxicity risk score > 7 were independently associated with higher odds of toxicity (Odds ratio [OR] 7.0; 95% confidence interval [CI] 1.1-44.6 and OR 4.3; 95% CI 1.0-17.7, respectively) in first cycle chemotherapy. Neither score was associated with OS.

CONCLUSIONS

Frailty predicts chemotherapy toxicity during first cycle. Frailty assessment may inform toxicity risk regardless of chronologic age.

Changes in Health-Related Quality of Life During Rehabilitation in Patients With Operable Lung Cancer: A Feasibility Study (PROLUCA)

INTRODUCTION

Surgical resection in patients with non-small cell lung cancer (NSCLC) may be associated with significant morbidity, functional limitations, and decreased quality of life.

OBJECTIVES

The objective is to present health-related quality of life (HRQoL) changes over time before and 1 year after surgery in patients with NSCLC participating in a rehabilitation program.

METHODS

Forty patients with NSCLC in disease stage I to IIIa, referred for surgical resection at the Department of Cardiothoracic Surgery RT, Rigshospitalet, were included in the study. The rehabilitation program comprised supervised group exercise program, 2 hours weekly for 12 weeks, combined with individual counseling. The study endpoints were self-reported HRQoL (Functional Assessment of Cancer Therapy-Lung, European Organization for Research and Treatment in Cancer-Quality of Life Questionnaire-QLQ-C30, Short-Form-36) and self-reported distress, anxiety, depression, and social support (National Comprehensive Cancer Network Distress Thermometer, Hospital Anxiety and Depression Scale, Multidimensional Scale of Perceived Social Support), measured presurgery, postintervention, 6 months, and 1 year after surgery.

RESULTS

Forty patients were included, 73% of whom completed rehabilitation. Results on emotional well-being ( P < .0001), global quality of life ( P = .0032), and mental health component score ( P = .0004) showed an overall statistically significant improvement during the study.

CONCLUSION

This feasibility study demonstrated that global quality of life, mental health, and emotional well-being improved significantly during the study, from time of diagnosis until 1 year after resection, in patients with NSCLC participating in rehabilitation.

Impact of physical exercise in cancer survivors during and after antineoplastic treatments

Cancer patients experience symptoms and adverse effects of treatments that may last even after the end of treatments. Exercise is a safe, non-pharmacological and cost-effective therapy that can provide several health benefits in cancer patient and survivors, reducing cancer symptoms and cancer treatment side effects. The purpose of this review is to describe how the physical exercise is capable to reduce cancer symptoms and cancer treatment side effects. We realized a pragmatic classification of symptoms, dividing them into physical, psychological and psycho-physical aspects. For each symptom we discuss causes, therapies, we analyse the effects of physical exercise and we summarize the most effective type of exercise to reduce the symptoms. This review also points out what are the difficulties that patients and survivors face during the practice of physical activity and provides some solutions to overcome these barriers. Related to each specific cancer, it emerges that type, frequency and intensity of physical exercise could be prescribed and supervised as a therapeutic program, like it occurs for the type, dose and duration of a drug treatment.

Exercise behavior and physical fitness in patients with advanced lung cancer

PURPOSE

The aim of this work was to evaluate exercise behavior and physical fitness of advanced lung cancer patients shortly after primary diagnosis.

METHODS

Between November 2013 and December 2016, advanced lung cancer patients (n = 227, mean age 62.2 years) were enrolled shortly after diagnosis and 211 patients were tested for endurance capacity (six-minute walk test) and strength performance (maximum voluntary isometric contraction of upper and lower extremities). Current and previous exercise and walking behavior were assessed using a self-reported questionnaire regarding type, frequency, intensity, and duration. Paired Student's t tests were used to compare physical fitness to reference data. The relation of potential determinants with physical fitness was assessed using linear regression analysis.

RESULTS

Exercise behavior was superior in the year before diagnosis compared to the time of study enrollment. Patients reduced frequency, intensity, and duration of sports/exercise after their lung cancer diagnosis. We observed significantly lower endurance capacity (p < .01) and strength performance in lower extremities (p < .01) in male and female patients compared to age and sex-matched reference data. We found significant correlations of previous exercise and walking behavior with physical fitness shortly after diagnosis in patients with advanced lung cancer.

CONCLUSION

Patients with advanced lung cancer showed impaired physical fitness regarding endurance and strength capacity. The strong decline in participation of sports/exercise shortly after diagnosis supports early implementation of physical exercise during anti-cancer treatment.
