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

International consensus is needed on a core outcome set to advance the evidence of best practice in cancer prehabilitation services and research

Prehabilitation aims to optimise patients' physical and psychological status before treatment. The types of outcomes measured to assess the impact of prehabilitation interventions vary across clinical research and service evaluation, limiting the ability to compare between studies and services and to pool data. An international workshop involving academic and clinical experts in cancer prehabilitation was convened in May 2022 at Sheffield Hallam University's Advanced Wellbeing Research Centre, England. The workshop substantiated calls for a core outcome set to advance knowledge and understanding of best practice in cancer prehabilitation and to develop national and international databases to assess outcomes at a population level.

Prehabilitation for Patients with Cancer Undergoing Radiation Therapy: a Scoping Review

AIMS

Prehabilitation is a process of identifying and assessing factors that could compromise the physical and psychological health of patients undergoing cancer treatment and implementing an intervention to combat such concerns. The use of prehabilitation in cancer surgery has yielded positive outcomes in rectal, lung and abdominal cancers. Prehabilitation strategies have potential to improve the management of patients receiving radiation therapy or chemoradiation. The aim of the present study was to map the evidence of the assessment and evaluation of prehabilitation for radiation therapy patients.

MATERIALS AND METHODS

A database search using EMBASE and PubMed was conducted. The PRISMA guidelines were adhered to. Keywords included prehabilitation, radiation therapy/radiotherapy, chemoradiotherapy/chemoradiation, intervention and exercise. Types of prehabilitation strategy, their purposes and impact, according to cancer site, were analysed.

RESULTS

Prehabilitation is most commonly evaluated in head and neck cancer, whereby unimodal, physical interventions manage dysphagia. Prehabilitation for lung cancer demonstrated its ability to widen treatment options for patients. Physical prehabilitation is administered to combat adverse effects of neoadjuvant chemoradiation therapy in patients with rectal cancer.

CONCLUSION

Prehabilitation is adaptive and tailored to specific patient and site needs; thus it is applied across a wide range of cancer sites. More interventions by which radiation therapy is the definitive treatment modality and larger sample sizes within these studies are warranted to increase prehabilitation utilisation for patients undergoing radiation therapy.

Rates of compliance and adherence to high-intensity interval training: a systematic review and Meta-analyses

BACKGROUND

To determine rates of compliance (i.e., supervised intervention attendance) and adherence (i.e., unsupervised physical activity completion) to high-intensity interval training (HIIT) among insufficiently active adults and adults with a medical condition, and determine whether compliance and adherence rates were different between HIIT and moderate-intensity continuous training (MICT).

METHODS

Articles on adults in a HIIT intervention and who were either insufficiently active or had a medical condition were included. MEDLINE, EMBASE, PsychINFO, SPORTDiscus, CINAHL, and Web of Science were searched. Article screening and data extraction were completed by two independent reviewers. Risk of bias was assessed using RoB 2.0 or ROBINS-I. Meta-analyses were conducted to discern differences in compliance and adherence between HIIT vs. MICT. Sensitivity analyses, publication bias, sub-group analyses, and quality appraisal were conducted for each meta-analysis.

RESULTS

One hundred eighty-eight unique studies were included (n = 8928 participants). Compliance to HIIT interventions averaged 89.4% (SD:11.8%), while adherence to HIIT averaged 63% (SD: 21.1%). Compliance and adherence to MICT averaged 92.5% (SD:10.6%) and 68.2% (SD:16.2%), respectively. Based on 65 studies included in the meta-analysis, compliance rates were not different between supervised HIIT and MICT interventions [Hedge's g = 0.015 (95%CI: - 0.088-0.118), p = .78]. Results were robust and low risk of publication bias was detected. No differences were detected based on sub-group analyses comparing medical conditions or risk of bias of studies. Quality of the evidence was rated as moderate over concerns in the directness of the evidence. Based on 10 studies, adherence rates were not different between unsupervised HIIT and MICT interventions [Hedge's g = - 0.313 (95%CI: - 0.681-0.056), p = .096]. Sub-group analysis points to differences in adherence rates dependent on the method of outcome measurement. Adherence results should be interpreted with caution due to very low quality of evidence.

CONCLUSIONS

Compliance to HIIT and MICT was high among insufficiently active adults and adults with a medical condition. Adherence to HIIT and MICT was relatively moderate, although there was high heterogeneity and very low quality of evidence. Further research should take into consideration exercise protocols employed, methods of outcome measurement, and measurement timepoints.

Nonlinear, Multicomponent Physical Exercise With Heart Rate Variability-Guided Prescription in Women With Breast Cancer During Treatment: Feasibility and Preliminary Results (ATOPE Study)

OBJECTIVE

The purpose of this study was to examine the feasibility, safety, adherence, and preliminary efficacy of the ATOPE program during radiotherapy (RT) or chemotherapy (CT) for women with breast cancer.

METHODS

This single-blind, pretest-posttest feasibility study included 38 women with breast cancer at the beginning of their treatment. The ATOPE program consisted of 12 to 18 sessions of a multimodal physical exercise program, prescribed based on daily heart rate variability and clinimetric assessments using the ATOPE+ mHealth system. Overall health was assessed with quality of life, autonomous balance, and body composition, whereas health-related fitness was measured through functional capacity, physical activity levels, and upper and lower limb strength.

RESULTS

The rates of recruitment, retention, and adherence were 52.35, 73.68, and 84.37%, respectively, and the satisfaction rating was 9.2 out of a possible 10 points. The perceived health status change score was 3.83 points, scored on a -5 to 5 point scale. No adverse effects were found. Compliance results showed that the ATOPE+ mHealth system was used on 73.38% of the days, and the Fitbit bracelet (Google, Mountain View, CA, USA) was used on 84.91% of the days. Women stayed physically active 55% of days. Regarding preliminary results, for overall health, the percentage of body fat in the RT group decreased by 1.93%, whereas it increased by 5.03% in the CT group. Lower limb strength increased in the RT group, specifically knee extensor isometric strength (6.07%), isokinetic knee flexors 180 degree/second (1.53%), and isokinetic knee extensors 300 degree/second (4.53%), in contrast with the reductions found in the CT group (11.07, 18.67, and 14.89%, respectively).

CONCLUSION

The ATOPE program, through nonlinear prescription based on daily monitoring with the ATOPE+ mHealth system, is feasible and safe for application during breast cancer treatment. The results suggest that the overall health can be maintained or even improved regarding most variables.

IMPACT

This study focused on the feasibility, safety, and completion of a physical therapist-led program at early diagnosis for adults with breast cancer. The multimodal, supervised, tailored, nonlinear physical exercise program is feasible and safe, showed a good completion rate, and was able to prevent the quality-of-life deficits that are often triggered by systemic breast cancer treatment. This study highlights the importance of daily morning assessments using the ATOPE+ mHealth system in patients with breast cancer to prescribe nonlinear physical exercise.

Prehabilitation in the lung cancer pathway: a scoping review

BACKGROUND

Lung cancer is the third most common type of cancer in the UK. Treatment outcomes are poor and UK deaths from lung cancer are higher than any other cancer. Prehabilitation has shown to be an important means of preparing patients both physically and psychologically for cancer treatment. However, little is understood about the context and mechanisms of prehabilitation that can impact physiological and psychological wellbeing. Our aim was to review and summarise primary research on prehabilitation in the lung cancer pathway using a realist approach.

METHODS

A scoping review of empirical primary research was conducted. Five online medical databases from 2016 - February 2023 were searched. All articles reporting on prehabilitation in lung cancer were included in the review. For this review, prehabilitation was defined as either a uni-modal or multi-modal intervention including exercise, nutrition and/or psychosocial support within a home, community or hospital based setting. A realist framework of context, mechanism and outcome was used to assist with the interpretation of findings.

RESULTS

In total, 31 studies were included in the review, of which, three were published study protocols. Over 95% of studies featured an exercise component as part of a prehabilitation programme. Twenty-six of the studies had a surgical focus. Only two studies reported using theory to underpin the design of this complex intervention. There was large heterogeneity across all studies as well as a lack of clinical trials to provide definitive evidence on the programme design, setting, type of intervention, patient criteria, delivery, duration and outcome measures used.

CONCLUSION

A standardised prehabilitation programme for lung cancer patients does not yet exist. Future lung cancer prehabilitation programmes should take into account patient led values, needs, goals, support structures and beliefs, as these factors can affect the delivery and engagement of interventions. Future research should consider using a conceptual framework to conceptualise the living with and beyond cancer experience to help shape and inform personalised prehabilitation services.

Effect of Exercise Training on Quality of Life, Symptoms, and Functional Status in Advanced-Stage Lung Cancer Patients: A Systematic Review

Advanced-stage lung cancer (LC) causes significant morbidity and impacts patients' quality of life (QoL). Exercise has been proven to be safe, feasible, and beneficial for symptom reduction and QoL improvement in many types of cancers, but research is limited in advanced-stage LC patients. This systematic review evaluates the effect of exercise interventions on the symptoms and QoL in patients with advanced-stage LC. Twelve prospective studies (744 participants) were included, evaluating different combinations of exercises and training such as aerobics, tai chi, strength, inspiratory muscle training, and relaxation. Studies found outcomes including but not limited to improved QoL, symptom burden, psychosocial health, functional status, and physical function. The results of this review support that exercise is safe and feasible with evidence supporting improved QoL and symptom mitigation. Integration of exercise should be considered in the individualized management of advanced-stage LC patients under the guidance of their healthcare providers.

High-intensity interval training and thromboembolic events during chemotherapy for testicular cancer: a retrospective analysis from the Body & Cancer cohort

Background: Men with testicular cancer receiving platinum-based chemotherapy have an increased risk of thromboembolic events, with incidence rates between 8-24%. A recent trial evaluating the effect of high-intensity interval training (HIIT) prematurely closed as three out of nine participants (33%) in the intervention group developed a thromboembolic event. The purpose of this retrospective cohort study was: 1) (primary) to evaluate the incidence of thromboembolic events in men receiving chemotherapy for testicular cancer who had participated in HIIT during a 6-week exercise program (Body & Cancer) 2) to describe the feasibility of this program.Material and methods: Forty men who had participated in at least one HIIT session from February 2007 to February 2020 were included. Electronic medical records were searched for incident thromboembolic events (arterial and venous) during Body & Cancer and up to one-year post-chemotherapy. Attendance, cardiorespiratory fitness (VO2-peak), and upper and lower extremity muscular strength (1 repetition maximum (RM)) were obtained from the Body & Cancer database.Results: One participant developed a thromboembolic event during Body & Cancer. No participants developed a thromboembolic event in the follow-up period. In all, data represent 160 HIIT sessions with a median attendance of eight sessions [range 1-19]. Statistically significant increases in upper and lower extremity strength were observed (8.6 (4.2 to 13.0) and 26.0 (14.9 to 37.0) kg, respectively). No significant increase in cardiorespiratory fitness was found (0.14 (-0.03 to 0.31) l/min).Conclusion: While conclusions on the safety of HIIT cannot be drawn, data from the present study do not support previous findings cautioning avoidance of HIIT due to a possible added risk of thromboembolic events in men receiving platinum-based chemotherapy for testicular cancer. Considering the potential for positive effects on cardiovascular outcomes associated with HIIT, future studies with robust design should be performed in this population to confirm these observations.

Harms of exercise training in patients with cancer undergoing systemic treatment: a systematic review and meta-analysis of published and unpublished controlled trials

Background

Exercise is recommended for people with cancer. The aim of this study was to evaluate the harms of exercise in patients with cancer undergoing systemic treatment.

Methods

This systematic review and meta-analysis included published and unpublished controlled trials comparing exercise interventions versus controls in adults with cancer scheduled to undergo systemic treatment. The primary outcomes were adverse events, health-care utilization, and treatment tolerability and response. Eleven electronic databases and trial registries were systematically searched with no date or language restrictions. The latest searches were performed on April 26, 2022. The risk of bias was judged using RoB2 and ROBINS-I, and the certainty of evidence for primary outcomes was assessed using GRADE. Data were statistically synthesised using pre-specified random-effect meta-analyses. The protocol for this study was registered in the PROESPERO database (ID: CRD42021266882).

Findings

129 controlled trials including 12,044 participants were eligible. Primary meta-analyses revealed evidence of a higher risk of some harms, including serious adverse events (risk ratio [95% CI]: 1.87 [1.47-2.39], I2 = 0%, n = 1722, k = 10), thromboses (risk ratio [95% CI]: 1.67 [1.11-2.51], I2 = 0%, n = 934, k = 6), and fractures (risk ratio [95% CI]: 3.07 [3.03-3.11], I2 = 0%, n = 203, k = 2) in intervention versus control. In contrast, we found evidence of a lower risk of fever (risk ratio [95% CI]: 0.69 [0.55-0.87], I2 = 0% n = 1109, k = 7) and a higher relative dose intensity of systemic treatment (difference in means [95% CI]: 1.50% [0.14-2.85], I2 = 0% n = 1110, k = 13) in intervention versus control. For all outcomes, we downgraded the certainty of evidence due to imprecision, risk of bias, and indirectness, resulting in very low certainty of evidence.

Interpretation

The harms of exercise in patients with cancer undergoing systemic treatment are uncertain, and there is currently insufficient data on harms to make evidence-based risk-benefits assessments of the application of structured exercise in this population.

Funding

There was no funding for this study.

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

INTRODUCTION

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

STATE OF THE ART

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

PERSPECTIVES

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

CONCLUSION

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

Is physical activity effective against cancer-related fatigue in lung cancer patients? An umbrella review of systematic reviews and meta-analyses

OBJECTIVES

To discuss the effects of physical activity on cancer-related fatigue (CRF) in lung cancer patients, summarize the types of physical activity in the published reviews, assess the quality of the evidence, and provide suggestions for the clinical selection of exercise intervention.

METHODS

PubMed, EMBASE, Web of Science, and the Cochrane Database of Systematic Reviews were searched through 8 November 2021 to identify relevant systematic reviews and meta-analyses. We also performed a manual search of the reference lists of included articles as supplements. Two researchers independently performed literature screening, data extraction, and quality assessment. The umbrella review has been registered in the International Prospective Register of Systematic Review (PROSPERO) registry (CRD42021292548).

RESULTS

From the 13 systematic reviews or meta-analyses identified, 10 physical activity interventions were included. The most mentioned intervention was aerobic combined with resistance exercise; however, no reduction of the symptoms of CRF was observed in lung cancer patients by this exercise intervention. Most of the patients who performed aerobic exercises alone showed improvement in CRF after the intervention. In addition, Tai Chi and breathing exercises have been shown to improve fatigue, but more high-quality research is still needed to support its effectiveness.

CONCLUSIONS

Aerobic exercise, respiratory muscle training, aerobic combined with balance training, and other exercise interventions have been shown to improve CRF in lung cancer patients. But it should be noted that according to the different treatment methods and disease stages of patients, individualized rehabilitation programs should be developed for patients. Due to the low methodological quality and evidence quality of some systematic reviews and meta-analyses included in this study, more high-quality clinical studies and systematic reviews are still needed for validation in the future. This umbrella review helps to identify effective ways of exercise to improve fatigue in lung cancer patients before dedicated evidence-based medical guidelines are established.

Functional and postoperative outcomes after high-intensity interval training in lung cancer patients: A systematic review and meta-analysis

Objective

The study evaluated the effects of high-intensity interval training (HIIT) on postoperative complications and lung function in patients with lung cancer compared to usual care.

Methods

We searched electronic databases in April 2022, including PubMed, Embase, the Cochrane Library, Web of Science, and the China National Knowledge Infrastructure (CNKI). Two authors independently applied the Cochrane Risk of Bias tool to assess the quality of RCTs. The postoperative complications, length of hospitalization, and cardiopulmonary functions from the studies were pooled for statistical analysis.

Results

A total of 12 randomized controlled trials were eligible for inclusion and were conducted in the meta-analysis. HIIT significantly increased VO_2peak (MD = 2.65; 95% CI = 1.70 to 3.60; I² = 40%; P <0.001) and FEV1 (MD = 0.12; 95% CI = 0.04 to 0.20; I² = 51%; P = 0.003) compared with usual care. A subgroup analysis of studies that applied HIIT perioperatively showed significant improvement of HIIT on FEV1 (MD = 0.14; 95% CI = 0.08 to 0.20; I² = 36%; P <0.0001). HIIT significantly reduced the incidence of postoperative atelectasis in lung cancer patients compared with usual care (RD = -0.16; 95% CI = -0.24 to -0.08; I² = 24%; P <0.0001). There was no statistically significant effect of HIIT on postoperative arrhythmias (RD = -0.05; 95% CI = -0.13 to 0.03; I² = 40%; P = 0.22), length of hospitalization (MD = -1.64; 95% CI = -3.29 to 0.01; P = 0.05), and the six-minute walk test (MD = 19.77; 95% CI = -15.25 to 54.80; P = 0.27) compared to usual care.

Conclusion

HIIT may enhance VO_2peak and FEV1 in lung cancer patients and reduce the incidence of postoperative atelectasis. However, HIIT may not reduce the incidence of postoperative arrhythmia, shorten the length of hospitalization, or improve the exercise performance of patients with lung cancer.

An exercise prescription for patients with lung cancer improves the quality of life, depression, and anxiety

Introduction

Lung cancer has the highest rates of morbidity and mortality among all cancers. Patients with lung cancer inevitably confront psychosocial discomforts and progressively experience depression and anxiety that potentially impact the clinical outcomes [e.g., quality of life (QoL)]. These mental disorders in patients with lung cancer may effectively be alleviated with prescribed Chinese traditional mind-body exercises. This study aimed to determine the effect of the exercise prescription containing Chinese traditional mind-body exercise on QoL, depression, and anxiety in patients with lung cancer.

Methods

In this study, 52 patients with non-small cell lung cancer (NSCLC) recruited from the China-Japan Friendship Hospital were divided into two groups, namely, the experimental group (N = 26) and the control group (N = 26). The experimental group was treated with an 8-week exercise prescription containing aerobic and resistance training. The control group received the usual care during the study period. The QoL, depression, and anxiety were separately investigated using EORTC QLQ-C30, EORTC QLQ-LC13, the Self-Rating Depression Scale (SDS), and the Self-Rating Anxiety Scale (SAS) at baseline and post-intervention. The scores of questionnaires were analyzed using the paired sample and independent sample t-tests to explore the intragroup and intergroup differences, respectively.

Results

The EORTC QLQ-C30 scores for physical functioning, role functioning, emotional functioning, and global QoL in the experimental group at post-intervention were significantly higher than those at baseline. The EORTC QLQ-C30 scores for fatigue, pain, dyspnea, and insomnia in the experimental group at post-intervention were significantly lower than those at the baseline. The SDS scores (baseline: 57.74 ± 8.77 vs. post-intervention: 51.42 ± 7.31, p < 0.05) and the SAS scores (baseline: 56.63 ± 9.39 vs. post-intervention: 49.16 ± 7.83, p < 0.05) in the experimental group at post-intervention were significantly lower than those at baseline.

Conclusions

The 8-week exercise prescription containing moderate-intensity Baduanjin (5 days per week) can effectively alleviate QoL, depression, and anxiety in patients with NSCLC. Our exercise prescription is an effective supportive treatment for lung cancer patients with depression and anxiety.

The Role of Exercise Before Cancer Treatment

OBJECTIVES

We aim to describe on the role of exercise in preparation for cancer treatments (prehabilitation) that include surgery and neoadjuvant or nonsurgical approaches. We discuss the evidence for the role of exercise and provide guidelines to exercise prescription and examples of the structure of prehabilitation exercise programs.

DATA SOURCE

We use peer-reviewed articles obtained through PubMed searches with search terms: exercise, oncology, cancer surgery, exercise physiology, respiratory exercises, prehabilitation, and behavior change.

CONCLUSION

The emergence of prehabilitation in preparing patients for cancer care has followed a rapidly upward trajectory over the past 20 years. Exercise prehabilitation remains the cornerstone of management, particularly in patients attending for major surgery. Multimodal approaches to supporting patients before cancer treatment are now well accepted and include screening and individualized treatments of functional, nutritional, and psychological impairments. Respiratory training before surgery and the addition of behavior change strategies to improve adherence to interventions and promote improved longer-term outcomes are now included in many prehabilitation programs. For exercise to be an effective treatment in improving fitness and strength, supervised aerobic and resistance exercises at moderate intensity are recommended. There remains debate regarding the use of higher-intensity exercise, the appropriate outcome to measure efficacy, and the mechanisms driving the efficacy of exercise.

IMPLICATIONS FOR NURSING PRACTICE

We provide background evidence and knowledge pertaining to the role and provision of exercise prehabilitation. Understanding screening, risk factors, and potential efficacy assists in knowing who to refer for prehabilitation and what the programs include. This enables more effective com munication with patients attending for cancer treatments.

Effect of adherence to treatment guidelines on overall survival in elderly non-small-cell lung cancer patients

OBJECTIVES

Mean age at diagnosis of lung cancer is increasing with increasing age in Western populations. The present study was designed to evaluate the effect of adherence to first-line treatment guidelines on overall survival (OS) in elderly patients with non-small-cell lung cancer (NSCLC) and reasons for non-adherence to treatment guidelines.

MATERIALS AND METHODS

All patients aged ≥ 65 years diagnosed with NSCLC in Ostrobothnia, Finland, during the years 2016 to 2020 were identified from hospital registries. Adherence of first-line treatment to contemporary treatment guidelines was analysed based on diagnosis, tumour stage and performance status (PS), as was the effect of adherence on OS.

RESULTS

A review of hospital registries identified 238 NSCLC patients aged ≥ 65 years. Guideline adherence by stage decreased significantly with age, with 66.4% of patients aged 65 to 74 years, but only 33.3% of those aged > 80 years treated according to guidelines (p < 0.001). Other factors associated with non-adherence to guidelines included poor PS, frailty, and limited lung function. Of the patients with PS 0-2, 26.9% were under-treated according to guidelines. Reasons for under-treatment included comorbidities, decreased lung function, physician decision to reduce treatment intensity or recommend best supportive care, patient choice and PS decline before treatment initiation. Guideline adherence increased overall OS of elderly NSCLC patients in all stages. Elderly PS 2 patients appear to benefit from guideline adherence and active treatment. In contrast, active treatment did not benefit patients with PS 3-4.

CONCLUSIONS

Guideline adherence was associated with increased OS in elderly NSCLC patients. Almost 10% of elderly and otherwise fit NSCLC patients were not treated according to guidelines and could have benefitted from more intensive treatment.

Effect of exercise on functional capacity in patients with advanced cancer: A meta-analysis of randomized controlled trials

PURPOSE

To determine the impact of exercise on functional capacity, measured through the "Six minutes walking test" (6MWT) in patients with advanced cancer stage.

METHODS

Systematic research on PubMed, Cochrane Library, and SportDiscus was conducted. Randomized controlled trials were eligible if they examined the effect of exercise on 6MWT.

RESULTS

Overall, a total of ten trials were included in the primary analysis. Compared to the controls, the exercise intervention was associated with an increase in functional capacity (+20.86 m; CI: -5.90 to 47.72, p = 0.12) although not reaching the statistical significance. Sensitivity analysis revealed an improvement for studies proposing a supervised exercise intervention towards the statistical significance. Few adverse events were associated with exercise training, and the median withdrawals rate was 17%.

CONCLUSIONS

Exercise may have a beneficial role on functional capacity in patients with advanced cancer, especially if supervised.

The Impact of a Nurse-Led Exercise Activity for Cancer-Related Fatigue in Patients With Leukemia

Many patients with leukemia experience cancer-related fatigue (CRF). However, when patients are admitted for treatment with chemotherapy, clinicians often overlook CRF and interventions that can help to manage it. The purpose of this four-week intervention was to determine whether a nurse-led exercise activity would reduce CRF and increase physical activity compared to current practice. The results suggest that nurse-led exercise programs can immediately decrease CRF and increase activity in admitted patients with leukemia receiving chemotherapy. Including patients in nurse-led exercise activities can support active participation in their own care during and after hospitalization.

Telerehabilitation physical exercise for patients with lung cancer through the course of their disease: A systematic review

BACKGROUND AND OBJECTIVE

Evidence is shown for the benefits of physical activity, for patients with lung cancer, at different times through the course of the disease. Telerehabilitation can overcome some of barriers often met by patients to practice physical activity. The objective of this systematic review is to assess feasibility and safety of telerehabilitation for patients with lung cancer, its effects on physical capacity, quality of life, symptoms severity, depression and anxiety, survival, lung function, post-operative outcomes, dyspnoea and body composition. Secondary aim was to distinguish the telerehabilitation efficacy between the different phases of the disease.

DATA SOURCE AND SELECTION CRITERIA

Pubmed, PEDro, Scopus, ScienceDirect, randomized controlled trials and non-randomized controlled trials, written in French or English, of telerehabilitation among patients with lung cancer.

RESULTS

Eight studies were included. Telerehabilitation is safe but was characterized by a low recruitment and attendance rate (<70%). It enhances quality of life, muscle mass, depression and anxiety but it does not improve physical capacity (except in preoperative period), symptoms severity, survival, lung function or dyspnoea. After surgery, it ameliorates quality of life, depression and anxiety. During systemic treatments of lung cancer, it improves quality of life, symptoms severity and muscle mass.

CONCLUSION

Telerehabilitation could be proposed in patients with lung cancer as a complementary intervention of hospital-based programme to increase physical activity volume, compliance and self-efficacy. In case the classic programmes are not possible, it could also be an alternative approach for patients unable to participate to a hospital or community-based training programme.

High-intensity interval training effects in cardiorespiratory fitness of lung cancer survivors: a systematic review and meta-analysis

PURPOSE

To assess the exercise intervention focused on high-intensity interval training (HIIT) in lung cancer survivors.

DESIGN

We performed a literature search using PubMed, Web of Science, and Science Direct (last search March 2021). Quality assessment and risk of bias were assessed using the Downs and Black scale and the Cochrane tool.

PARTICIPANTS

A total of 305 patients of 8 studies were assessed, with their mean age ranging from 61 ± 6.3 to 66 ± 10 years in the exercise group and from 58.5 ± 8.2 to 68 ± 9 years in the control group.

METHODS

A systematic review and meta-analysis of randomized controlled trials and pilot randomized controlled trials was performed. We included controlled trials testing the effect of HIIT in lung cancer survivors versus the usual care provided to these patients. The data were pooled and a meta-analysis was completed for cardiorespiratory fitness (VO_2peak).

RESULTS

We selected 8 studies, which included 305 patients with lung cancer: 6 studies were performed around surgical moment, one study during radiotherapy's treatment, and other during target therapy. After pooling the data, exercise capacity was included in the analysis. Results showed significant differences in favour to HIIT when compared to usual care in cardiorespiratory fitness (standard mean difference = 2.62; 95% confidence interval = 1.55, 3.68; p < 0.00001).

CONCLUSIONS AND IMPLICATIONS

The findings indicated a beneficial effect of HIIT for improving cardiorespiratory fitness in lung cancer patients in early stages around oncological treatment moment. Nevertheless, this review has several limitations, the total number of studies was low, and the stage and subtype of lung cancer patients were heterogeneous that means that the conclusions of this review should be taken with caution.

Can high-intensity interval training improve mental health outcomes in the general population and those with physical illnesses? A systematic review and meta-analysis

OBJECTIVE

High-intensity interval training (HIIT) is a safe and feasible form of exercise. The aim of this meta-analysis was to investigate the mental health effects of HIIT, in healthy populations and those with physical illnesses, and to compare the mental health effects to non-active controls and other forms of exercise.

DESIGN

Random effects meta-analyses were undertaken for randomised controlled trials (RCTs) comparing HIIT with non-active and/or active (exercise) control conditions for the following coprimary outcomes: mental well-being, symptoms of depression, anxiety and psychological stress. Positive and negative affect, distress and sleep outcomes were summarised narratively.

DATA SOURCES

Medline, PsycINFO, Embase and CENTRAL databases were searched from inception to 7 July 2020.

ELIGIBILITY CRITERIA FOR SELECTING STUDIES

RCTs that investigated HIIT in healthy populations and/or those with physical illnesses and reported change in mental well-being, depression, anxiety, psychological stress, positive/negative affect, distress and/or sleep quality.

RESULTS

Fifty-eight RCTs were retrieved. HIIT led to moderate improvements in mental well-being (standardised mean difference (SMD): 0.418; 95% CI: 0.135 to 0.701; n=12 studies), depression severity (SMD: -0.496; 95% CI: -0.973 to -0.020; n=10) and perceived stress (SMD: -0.474; 95% CI: -0.796 to -0.152; n=4) compared with non-active controls, and small improvements in mental well-being compared with active controls (SMD:0.229; 95% CI: 0.054 to 0.403; n=12). There was a suggestion that HIIT may improve sleep and psychological distress compared with non-active controls: however, these findings were based on a small number of RCTs.

CONCLUSION

These findings support the use of HIIT for mental health in the general population.

LEVEL OF EVIDENCE

The quality of evidence was moderate-to-high according to the Grading of Recommendations Assessment, Development and Evaluation) criteria.

Effects of high-intensity training on the quality of life of cancer patients and survivors: a systematic review with meta-analysis

Cancer and associated medical treatments affect patients' health-related quality of life (HRQoL) by decreasing functional dimensions of physical, social, cognitive, and emotional well-being, while increasing short and late-term symptoms. Exercise, however, is demonstrated to be a useful therapy to improve cancer patients' and survivors' HRQoL, yet the effectiveness of high-intensity training (HIT) exercise is uncertain. This systematic review and meta-analysis aimed to analyse the effects of HIT on HRQoL dimensions in cancer patients and survivors as well as evaluate the optimal prescription of HIT. The search followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines (PRISMA) and examined Web of Science and PubMed (Medline) databases. Data were analysed utilizing Review Manager Software. Twenty-two articles were included in the systematic review and 17 in the meta-analysis. Results showed HIT improved global quality of life, physical functioning, role functioning, social functioning, cognitive functioning, fatigue, pain, dyspnea, and insomnia, compared to an inactive control group, yet no differences were found between HIT and low to moderate-intensity exercise interventions. Particular improvements in HRQoL were observed during cancer treatment and with a training duration of more than eight weeks, a frequency of 2 days/week, and a volume of at least 120 min/week, including 15 min or more of HIT. Our findings whilst encouraging, highlight the infancy of the extant evidence base for the role of HIT in the HRQoL of cancer patients and survivors.

Multimodal Exercise Program: A Pilot Randomized Trial for Patients With Lung Cancer Receiving Surgical Treatment

BACKGROUND

Curative lung resection is the best option for patients with stage I-III lung cancer, and the best exercise intervention in these patients has not been determined.

OBJECTIVES

This pilot study explored whether a short-term pre- and postsurgery multimodal exercise program affected dyspnea, exercise capacity, inspiratory capacity, anxiety, and depression.

METHODS

A total of 101 patients were randomly allocated into the combined intervention group (n = 34), the breathing exercise group (n = 32), or the control group (n = 35). During hospitalization, patients in the two intervention groups received one or more kinds of exercise intervention, and patients in the control group only received usual care. Outcomes were assessed at admission, on the day before surgery, and at discharge.

FINDINGS

Both intervention groups achieved significant improvements in dyspnea, exercise capacity, and inspiratory capacity, and patients in the combined intervention group exhibited greater improvements in outcomes as compared to those randomized to the breathing exercise group.

Effect of Exercise Interventions on Quality of Life in Patients With Lung Cancer: A Systematic Review of Randomized Controlled Trials

PROBLEM IDENTIFICATION

Improving quality of life (QOL) is a key issue for patients with lung cancer. Exercise interventions could positively affect patients' QOL; however, there is no clear-cut understanding of the role of exercise in improving QOL in patients with lung cancer.

LITERATURE SEARCH

The PubMed®, Embase®, Cochrane Library, and Web of Science electronic databases were searched from inception to September 6, 2019.

DATA EVALUATION

16 randomized controlled trials met the inclusion criteria. A qualitative synthesis method was used to identify the effect of exercise interventions on QOL in patients with lung cancer.

SYNTHESIS

This review indicates that exercise interventions may have beneficial effects on the QOL of patients with lung cancer. The effectiveness seems to be affected by the duration of the intervention, as well as exercise frequency, intensity, and adherence.

IMPLICATIONS FOR PRACTICE

Exercise interventions can be integrated into management plans for patients with lung cancer to improve their QOL. Healthcare providers should consider developing optimal exercise prescriptions to maximize the results for this population.

Attention to the Principles of Exercise Training in Exercise Studies of Persons With Lung Cancer: A Systematic Review

The authors systematically reviewed and summarized exercise trials in persons with lung cancer on (a) attention to the principles of exercise training (specificity, progression, overload, initial values, reversibility, and diminishing returns); (b) methodological reporting of FITT (frequency, intensity, time, and type) components; and (c) reporting on participant adherence to prescribed FITT. Randomized controlled trials of exercise that reported on ≥1 physical fitness, physical function, or body composition outcome in persons with lung cancer were included. Of 20 trial arms, none incorporated all principles of exercise training. Specificity was included by 95%, progression by 45%, overload by 75%, and initial values by 80%, while one trial arm applied reversibility and diminishing returns. Fourteen interventions reported all FITT components; however, none reported adherence to each component. Including the principles of training and reporting FITT components will contribute to better understanding of the efficacy of exercise for persons with lung cancer and inform evidence-based exercise prescriptions.

Effect of Exercise on Fatigue in Patients with Lung Cancer: A Systematic Review and Meta-Analysis of Randomized Trials

Background: Fatigue is a frequent debilitating symptom among patients with lung cancer. The effect of exercise on fatigue remains to be quantified. Objective: This review aimed to examine the effect of exercise on fatigue by synthesizing findings from randomized controlled trials (RCTs). Methods: This systematic review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. A systematic search was conducted in five electronic databases from inception to March 2020. Only RCT was included. The primary outcome was fatigue and the secondary outcomes included depression, anxiety, quality of life, and functional capacity. Pooled weighted or standardized mean difference (WMD or SMD) with 95% confidence interval (CI) was calculated. Results: Eight RCTs were included. The exercise intervention was delivered in the supervised environment (n = 6) or free-living settings (n = 2). Exercise reduced the level of fatigue (SMD = -0.33; 95% CI = -0.54 to -0.13). Exercise also decreased depressive symptom (WMD = -1.57; 95% CI = -2.69 to -0.44) and anxiety (WMD = -1.39; 95% CI = -2.60 to -0.18). Exercise showed a moderate effect on the quality of life, with an SMD of 0.33 (95% CI = 0.08 to 0.58). Exercise intervention increased functional capacity as measured by the six-minute walk test by 20 meters (95% CI = 14.2 to 55.0), but the effect was not significant (p = 0.247). Conclusion: Exercise demonstrated a moderate effect on fatigue in patients with lung cancer. Exercise also improved depressive symptoms, anxiety, and quality of life; however, its impact on functional capacity was not significant. More clinical trials are warranted to explore the mechanisms underlying the impact of exercise on fatigue. Strategies improving adherence to exercise prescription should be developed to help these patients overcome potential challenges.

Physiologic and psychologic adaptation to exercise interventions in lung cancer patients undergoing chemotherapy: a systematic review and meta-analysis of randomized controlled trials

OBJECTIVE

The purpose of this meta-analysis is to investigate the effectiveness of exercise interventions in patients with lung cancer (LC) during chemotherapy regarding physiological and psychological outcomes.

METHODS

Databases including MEDLINE and EMBASE were used to find relevant randomized controlled trails that explored outcomes of exercise interventions for patients with LC during chemotherapy up to June 2020. Effect sizes were calculated by standardized mean difference statistics.

RESULTS

Six studies were included that involved 244 participants with average age of 65 years. Patients with LC participating in exercise interventions during chemotherapy had significantly increased strength, forced expired volume, and quality of life as well as significantly decreased pain. Effective exercise intervention characteristics were combined aerobic and resistance exercise, performance more than 5 times a week, moderate to vigorous intensity, and 1-h sessions.

CONCLUSION

Supervised participation in exercise improves strength, forced expired volume, and quality of life and relieves pain and depression during chemotherapy.

High-intensity interval training in the prehabilitation of cancer patients-a systematic review and meta-analysis

PURPOSE

To evaluate the impact of high-intensity interval training (HIIT) on health-related outcome parameters in the prehabilitation of patients diagnosed with cancer.

METHODS

A systematic review and meta-analysis of comparative studies on HIIT in cancer prehabilitation conducted by screening standard databases from their inception to March 30, 2020. Outcomes of interest included cardiorespiratory fitness, feasibility, safety, clinical, and patient-reported outcomes.

RESULTS

Of the 855 identified studies, 8 articles met the inclusion criteria (7 randomized, 1 non-randomized controlled trial) with a total of 896 patients. The study protocols were heterogeneous, but the methodological quality ranged from good to high according to PEDro scale. Meta-analysis revealed a significant improvement of peak oxygen consumption (VO₂peak) achieved with HIIT compared to usual care. Furthermore, HIIT was feasible and safe, showing low risk of adverse events and positive effects on health-related outcomes in prehabilitative settings.

CONCLUSION

In the phase of prehabilitation, HIIT has potential health benefits in patients diagnosed with cancer and is feasible and safe to perform. Nonetheless, larger randomized controlled trials focusing on long-term effects (such as cancer recurrence or survival rates) are missing, to underline the potential relevance of HIIT for cancer patients.

Exercise for Individuals With Lung Cancer: A Systematic Review and Meta-Analysis of Adverse Events, Feasibility, and Effectiveness

BACKGROUND

The purpose of this systematic review and meta-analysis was to evaluate the safety (adverse events), feasibility (recruitment, retention, and adherence) and effectiveness of exercise among individuals with lung cancer.

DATA SOURCES

Electronic databases (CINAHL, Cochrane, Ebscohost, MEDLINE, Pubmed, ProQuest Health and Medical Complete, ProQuest Nursing and Allied Health Source, Science Direct, and SPORTDiscus) were searched for randomized, controlled, exercise trials involving individuals with lung cancer that were published prior to May 1, 2020. The PEDro scale was used to assess risk of bias, and the Common Terminology Criteria for Adverse Events was used to classify adverse event severity. Feasibility was assessed by computing median (range) recruitment, retention, and exercise attendance rates. Meta-analyses were performed to evaluate adverse event risk between exercise and usual care, and effects on health outcomes. Subgroup effects for exercise mode, supervision, intervention duration, diagnosis or treatment-related factors, and trial quality were assessed.

RESULTS

Thirty-two trials (n=2109) involving interventions ranging between 1 and 20 weeks were included. Interventions comprised of aerobic (n=13, 41%), resistance (n=1, 3%), combined aerobic and resistance (n=16, 50%) and other exercise (n=2, 6%). There was no difference in the risk of an adverse event between exercise and usual care groups (exercise: n=64 events; usual care: n=61 events]; risk difference: -0.01 [91% CI = -0.02, 0.01]; P = .31). Median recruitment rate was 59% (9%-97%), retention rate was 86% (50%-100%), and adherence rate was 80% (44%-100%). Significant effects of exercise compared to usual care were observed for quality of life, aerobic fitness, upper-body strength, lower-body strength, anxiety, depression, forced expiratory volume, and sleep (standardized mean difference range=0.20-0.59). Subgroup analyses showed that safety, feasibility, and effect was similar irrespective of exercise characteristics, stage at diagnosis, treatment (surgery and chemotherapy), and trial quality.

CONCLUSION

For individuals with lung cancer (stages I-IV), the risk of an adverse event with exercise is low. Exercise can be feasibly undertaken post-diagnosis and leads to improvements in health-related outcomes. Together, these findings add weight behind the importance of integrating exercise into standard cancer care, including for this specific cancer type.

IMPLICATIONS FOR NURSING PRACTICE

Exercise should be considered as part of the treatment for all patients with lung cancer at any stage. Exercise has been shown to be low risk and can be feasibly undertaken by patients. The ideal mode, intensity, frequency, or duration of exercise for all patients with lung cancer is not known. Nonetheless, these findings support endorsement of cancer-specific physical activity guidelines, as well as referral to an exercise professional, such as an exercise physiologist or physiotherapist, for those diagnosed with lung cancer.

Effects of exercise therapy in cancer patients undergoing radiotherapy treatment: a narrative review

Despite its beneficial effects, radiotherapy still results in a range of side effects that negatively impact quality of life of patients. Exercise has been shown to counteract the side effects induced by cancer treatment. This narrative review aims to provide an up-to-date review of the effects of an exercise intervention in cancer patients during radiotherapy. A literature search was performed on PubMed to identify original articles that evaluated the effects of an exercise programme to alleviate treatment-related side effects in cancer patients undergoing radiotherapy with or without other cancer treatments. Benefits related to exercise training have been shown in breast, prostate, rectal, lung, head and neck cancer patients undergoing radiotherapy. Therefore, exercise should be considered as a concurrent treatment alongside radiotherapy to alleviate treatment-related side effects and facilitate effective recovery. Due to the onset and progress of treatment-related side effects throughout radiotherapy, a regular clinical evaluation seems strongly advisable in order to continuously adapt the exercise programme depending on symptoms and side effects. An exercise professional is needed to personalize exercise training based on the medical condition and tailor it throughout the intervention according to progress and the patient’s medical status. Future studies are needed to confirm the potential benefits of exercises observed on treatment-related side effects. Furthermore, because of the narrative design of this study, a systematic review is required to evaluate the strength of the evidence reported.

Efficacy and Safety of an mHealth App and Wearable Device in Physical Performance for Patients With Hepatocellular Carcinoma: Development and Usability Study

Background

Exercise is predicted to have a positive effect among hepatocellular carcinoma (HCC) patients. However, these patients are hesitant to start and build up an exercise program for one major reason: the vague fear of developing hepatic decompensation, a potentially fatal condition that can lead to death. Integrating mobile health (mHealth) with individualized exercise programs could be a possible option for promoting physical capacity among HCC patients.

Objective

The aim of this study was to evaluate the efficacy and safety of rehabilitation exercises, which have been individually prescribed via an mHealth app, on physical fitness, body composition, biochemical profile, and quality of life among HCC patients.

Methods

A total of 37 HCC patients were enrolled in a 12-week course with an mHealth app program targeted to HCC patients. The wearable wristband device Neofit (Partron Co) was provided to participants, and recorded daily physical data, such as the number of steps, calorie expenditure, exercise time, and heart rate. Each participant was given an individualized rehabilitation exercise program that was prescribed and adjusted at the 6-week midintervention period based on the assessment results. At baseline, 6-week, and 12-week sessions, participants’ physical fitness levels (ie, 6-minute walk test, grip strength test, and 30-second chair stand test) were measured. Physical activity levels, as measured by the International Physical Activity Questionnaire-Short Form (IPAQ-SF); body composition (ie, body mass index, body fat percentage, and muscle mass); biochemical profiles; and quality of life, as measured by the European Organization for Research and Treatment of Cancer Quality-of-Life Questionnaire C30, were assessed at baseline and at the end point. At the 6-week midpoint, exercise intensity was individually adjusted.

Results

Of the 37 patients, 31 (84%) completed the 12-week intervention. Grip strength improved significantly after 12 weeks of the intervention. The 30-second chair stand test and the 6-minute walk test showed significant improvement from 0 to 6 weeks, from 0 to 12 weeks, and from 6 to 12 weeks. Muscle mass and the IPAQ-SF score increased significantly after 12 weeks of the intervention without biochemical deterioration.

Conclusions

Following 12 weeks of mHealth care, including an individually prescribed rehabilitation exercise program, we saw significant improvements in physical fitness, body composition, and physical activity without any complication or biochemical deterioration among compensated HCC patients who had completed therapy.
