A structured exercise program for patients with advanced non-small cell lung cancer

Effectiveness of Baduanjin exercise on pulmonary function, quality of life, psychological well-being and exercise tolerance in postoperative patients with non-small cell lung cancer: Systematic review and meta-analysis of randomized controlled trials

OBJECTIVE

To evaluate the influence of engaging in Baduanjin exercise on pulmonary function, quality of life (QoL), mental well-being and exercise tolerance among postoperative individuals diagnosed with non-small cell lung cancer (NSCLC).

METHODS

A comprehensive search of randomized controlled trials (RCTs) in eleven different electronic databases, spanning from their inception up until July 3, 2024, was conducted. Following this exhaustive search, the literature was thoroughly screened, relevant information was carefully extracted, and the potential for bias within the selected studies was critically evaluated by two independent researchers. Employing Revman 5.4 software, statistical analyses were then carried out.

RESULTS

A comprehensive compilation of 6 RCTs, involving a collective 540 patients diagnosed with NSCLC, was analyzed. The pooled findings revealed that engaging in Baduanjin exercise leads to a significant enhancement in forced vital capacity (FVC) (WMD=0.23, 95% CI=0.06 ∼ 0.41, P = 0.009), forced expiratory volume in the first second (FEV1) (WMD=0.16, 95% CI=0.00 ∼ 0.32, P = 0.05) in NSCLC patients, as well as QoL (WMD=24.09, 95% CI=20.68 ∼ 27.51, P<0.00001) and functional well-being (WMD=6.70, 95% CI=5.50 ∼ 7.90, P < 0.00001). Meanwhile, Baduanjin exercise reduced Self-Rating Anxiety Scale (SAS) (WMD=-9.58, 95% CI=-10.58 ∼ -8.58, P < 0.00001) scores in patients with NSCLC. However, sensitivity analyses revealed that the results for physical well-being, social/family well-being, emotional well-being, lung cancer subscales, Self-Rating Depression Scale (SDS) scores, and 6 min walk distance (6MWD) lacked robustness. Subgroup analysis was conducted based on the intervention frequency, revealed that both 3 and 10 weekly training sessions improved 6MWD in NSCLC patients. Notably, 10 weekly training sessions (WMD=54.72, 95% CI=28.76 ∼ 80.69, P<0.0001) were found to be twice as effective as 3 weekly training sessions (WMD=26.96, 95% CI=17.31 ∼ 36.61, P<0.00001) in enhancing 6MWD . However, no improvement in 6MWD was observed in the 8 weekly training sessions (WMD=-18.34, 95%CI=-41.55 ∼ 4.87, P<0.00001).

CONCLUSION

The meta-analysis revealed that for individuals diagnosed with NSCLC, Baduanjin exercise demonstrated significant effectiveness in terms of pulmonary function enhancement, QoL elevation, anxiety alleviation and exercise endurance improvement. However, the methodological limitations significantly constrain the strength of clinical evidence. Meanwhile, the lack of robustness in some outcomes as indicated by sensitivity analyses, suggest significant constraints in the external validity and generalizability of the findings to broader populations.

Exercise interventions for older adults with advanced cancer: A scoping review

INTRODUCTION

The feasibility, safety, acceptability, and perceptions of exercise in older adults with advanced disease are not well understood due to the scarcity of evidence. This scoping review aimed to (1) summarize evidence on the feasibility, acceptability, and safety of exercise interventions for older adults with advanced cancer and (2) explore this population's perceptions on participating in exercise programs.

MATERIALS AND METHODS

A systematic search was conducted by an expert research librarian in Medline, CINAHL, EMBASE, Cochrane CENTRAL, and SPORTDiscus (inception through November 2023). Eligible studies included older adults with advanced (stage IV or receiving treatment with non-curative intent) solid cancers and intervention or qualitative studies on physical activity/exercise in older adults pertaining to our objectives.

RESULTS

A total of 36 studies were included: 28 (78 %) intervention studies, seven (19 %) qualitative studies, and one (3 %) cross-sectional study. The Frequency/Intensity/Time/Type (FITT) principle was described in 18 studies (64 %). Feasibility was examined in 15 of the 28 intervention studies (54 %) using various definitions. Four studies had predetermined feasibility thresholds, yielding mixed results. One intervention study reported on two intervention-related severe adverse events. Nineteen of the 28 intervention studies (68 %) examined acceptability, reporting high levels of participant satisfaction. Qualitative data revealed several barriers and facilitators to exercise.

DISCUSSION

Exercise appears to be feasible, acceptable, and safe in older adults with advanced cancer. Consistent reporting on the FITT principle and feasibility operationalization are areas of improvement in exercise studies in older adults with advanced disease.

Mitigation of decline with virtual exercise with lung cancer (MoVE with lung cancer) - A promising approach to enhance physiological strength, improve body composition, and build upon current evidence

INTRODUCTION

Exercise can mitigate declines in physical function for patients with cancer, but in-person exercise programs for patients with advanced lung cancer often face low recruitment and retention. This prospective study assessed the feasibility of virtual exercise for patients with advanced lung cancer.

METHODS

Mitigation of decline with Virtual Exercise (MoVE) with Lung Cancer was a prospective, single-arm, feasibility study. Patients with advanced lung cancer undergoing systemic therapy in British Columbia, Canada participated in a 12-week group exercise program delivered twice weekly via Zoom. Feasibility measures included accrual, recruitment rate, attendance, adherence, attrition, adverse events, and group belongingness. Efficacy was assessed via effect on physical function, cardiovascular fitness, body composition, and quality of life (QoL).

RESULTS

Twenty-seven patients were enrolled (median age = 66 years). Most had adenocarcinoma (92 %) and were on targeted therapy (73 %). Recruitment rate was 61 %, attrition 4 %, attendance 87 %, and adherence 96 %. Significant improvements were seen in gait speed (Z = 2.759, p = 0.006), 30-second chair stand (Z = 3.810, p < 0.001), 30-second bicep curl (Z = 4.209, p < 0.001), 8-foot timed up and go (Z = -3.148, p = 0.002), six minute walk test (Z = 3.124, p = 0.002), and QoL (FACT-G post hoc p = 0.005). Participants' skeletal muscle index increased by 0.9 cm2 (p = 0.033). Participant satisfaction was high (4.6/5).

CONCLUSIONS

A 12-week virtually supervised exercise program for patients with advanced lung cancer showed high attendance and adherence, with significant improvements in physical function and positive participant feedback. These results demonstrate that physical function can be maintained or improved during systemic treatments for advanced lung cancer.

Digital Therapeutics-Based Cardio-Oncology Rehabilitation for Lung Cancer Survivors: Randomized Controlled Trial

BACKGROUND

Lung cancer ranks as the leading cause of cancer-related deaths. For lung cancer survivors, cardiopulmonary fitness is a strong independent predictor of survival, while surgical interventions impact both cardiovascular and pulmonary function. Home-based cardiac telerehabilitation through wearable devices and mobile apps is a substitution for traditional, center-based rehabilitation with equal efficacy and a higher completion rate. However, it has not been widely used in clinical practice.

OBJECTIVE

The objective of this study was to broaden the use of digital health care in the cardiopulmonary rehabilitation of lung cancer survivors and to assess its impact on cardiopulmonary fitness and quality of life (QOL).

METHODS

Early-stage nonsmall cell lung cancer survivors aged 18-70 years were included. All the participants received surgery 1-2 months before enrollment and did not require further antitumor therapy. Participants were randomly assigned to receive cardiac telerehabilitation or usual care for 5 months. Artificial intelligence-driven exercise prescription with a video guide and real-time heart rate (HR) monitoring was generated based on cardiopulmonary exercise testing. Aerobic exercise combining elastic band-based resistance exercises were recommended with a frequency of 3-5 d/wk and a duration of 90-150 min/wk. The effective exercise duration was recorded when patients' HR reached the target zone (HRresting + [HRmax - HRresting] × [≈40%-60%]), representing the duration under the target intensity. The prescription used a gradual progression in duration and action intensity based on the exercise data and feedback. Outcome measurements included cardiopulmonary fitness; lung function; cardiac function; tumor marker; safety; compliance; and scales assessing symptoms, psychology, sleep, fatigue, and QOL.

RESULTS

A total of 40 (85%) out of 47 patients finished the trial. The average prescription compliance rate of patients in the telerehabilitation group reached 101.2%, with an average exercise duration of 151.4 min/wk and an average effective exercise duration of 92.3 min/wk. The cardiac telerehabilitation was associated with higher improvement of maximal oxygen uptake peak (3.66, SD 3.23 mL/Kg/min vs 1.09, SD 3.23 mL/Kg/min; P=.02) and global health status or QOL (16.25, SD 23.02 vs 1.04, SD 13.90; P=.03) compared with usual care. Better alleviation of affective interference (-0.88, SD 1.50 vs 0.21, SD 1.22; P=.048), fatigue (-8.89, SD 15.96 vs 1.39, SD 12.09; P=.02), anxiety (-0.31, SD 0.44 vs -0.05, SD 0.29; P=.048), and daytime dysfunction (-0.55, SD 0.69 vs 0.00, SD 0.52; P=.02) was also observed in the telerehabilitation group. No exercise-related adverse events were identified during the intervention period.

CONCLUSIONS

The 5-month, digital therapeutics-based telerehabilitation improved cardiorespiratory fitness in lung cancer survivors with good compliance and safety. Patients receiving telerehabilitation also reported improved QOL with reduced levels of fatigue, anxiety, and daytime dysfunction.

Exercise in cancer care for people with lung cancer: A narrative synthesis

OBJECTIVES

Lung cancer is the second most common cancer diagnosed worldwide, resulting in significant physical and psychological consequences. In this narrative review, we explore the role of exercise as an adjunct therapy to counteract health issues experienced by people before, during and after treatment for lung cancer, and offer recommendations for exercise prescription and future research.

DESIGN

Narrative cornerstone review.

METHODS

A narrative review was conducted to explore the role of exercise in cancer care for people diagnosed with lung cancer.

RESULTS

Improvements in fitness, strength and quality of life have been demonstrated in people with lung cancer following participation in exercise programmes before, during and post treatment. Whilst combined aerobic (50-100 % heart rate maximum) and resistance (50-85 % of 1 repetition maximum) training, 2-5 times per week across the cancer continuum is typically prescribed, few people with lung cancer currently access exercise services. 'Optimal' exercise prescription is unclear, although is likely individual-specific. The immediate priority is to identify a tolerable starting exercise dosage, with the side effects of lung cancer and its treatment on the respiratory system, particularly shortness of breath (dyspnoea), likely driving the initial maximum threshold for session mode, duration and intensity. To date, exercise safety for people with lung cancer has been poorly evaluated and reported - few trials report it, but those that do report small numbers of serious adverse events.

CONCLUSIONS

Recommendations for health professionals prescribing exercise therapy to people with lung cancer are provided, with consideration of the strengths and limitations of the current evidence base.

Effect of exercise for patients with advanced lung cancer and cancer-related fatigue: A systematic review and meta-analysis

BACKGROUND

Cancer-related fatigue (CRF) is a significant burden for patients with advanced lung cancer. While exercise is recommended for managing CRF during pre- and active treatment phases, evidence supporting its efficacy in advanced stage remains limited. This systematic review and meta-analysis aimed to quantify the effects of exercise on CRF and its common complications in patients with advanced lung cancer.

METHODS

A systematic search of 4 databases (PubMed, Embase, Cochrane, and Web of Science) was conducted up to July 10, 2024 to identify relevant randomized controlled trials (RCTs). Studies were selected based on predefined eligibility criteria, including adult patients with advanced lung cancer reporting fatigue as an outcome. Study selection followed Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) 2020 guidelines, and the risk of bias was assessed using the Cochrane Risk of Bias tool (RoB 2.0). The quality of evidence was evaluated with the Grading of Recommendations Assessment, Development and Evaluation (GRADE) system. Random- or fixed-effects models were used for meta-analyses based on heterogeneity levels.

RESULTS

Eight RCTs involving 749 patients were included. Meta-analysis revealed that exercise significantly improved CRF in patients with advanced lung cancer (standardized mean difference (SMD) = -0.33; 95% confidence interval (95%CI): -0.54 to -0.12); p = 0.00; I2 = 0.00%). Subgroup analysis showed greater efficacy in patients aged ≤60 years (p = 0.028), those engaging in traditional Chinese exercise (p = 0.003), and interventions lasting fewer than 12 weeks (p = 0.017). Exercise also significantly improved quality of life (SMD = 0.29; 95%CI: 0.02-0.55; p = 0.04; I2 = 0.00%) and reduced dyspnea (SMD = -0.43; 95%CI: -0.71 to -0.16; p = 0.00; I2 = 0.00%). No significant effects were observed on sleep quality, anxiety, or depression. The risk of bias across studies was moderate, and the quality of evidence, as evaluated by GRADE, was rated as low due to study limitations. Adverse events were minimal, with only one mild, exercise-related event reported.

CONCLUSION

Exercise significantly alleviates CRF in patients with advanced lung cancer, improves certain complications, and enhances quality of life. The intervention's effectiveness varies by age, type of exercise, and duration. Further high-quality studies are needed to validate these findings.

Effect of a Physical Exercise Intervention on Physical Function Parameters and Blood Analytical Changes in Lung Cancer Survivors: A Feasibility Study

Background: Lung cancer carries a high burden of systemic symptoms, including in survivors, leading to a reduced quality of life (QoL). We assessed whether a 12-week multicomponent supervised exercise programme, including muscular strength and aerobic training, was beneficial in patients who had undergone surgery for early non-small cell lung cancer (NSCLC) in terms of physical performance, QoL, and metabolic and nutritional analytical parameters. Methods: Physical performance was measured by gait speed, handgrip strength, 30 s sit-to-stand (30s-STS) test repetitions, distance covered in the 6 min walk test (6MWT), and the Short Physical Performance Battery (SPPB) score. QoL was assessed with the EORTC-QLQ-C30 questionnaire. Blood glucose, cholesterol, triglycerides, total proteins, albumin, pre-albumin, creatinine, c-reactive protein, insulin-growth factor 1 (IGF-1), and the haemoglobin and hematocrit percentages were measured before and after the intervention in order to observe any beneficial effects related to metabolic markers. Results: After the intervention, the mean scores for the 6MWT (p < 0.001), STS (p < 0.001), 6MWT (p < 0.01), and SPPB (p < 0.01) had significantly improved. However, handgrip strength and nutritional analytical were unchanged. The EORTC-QLQ-C30 functions and symptoms significantly improved after the intervention (p < 0.05 and p < 0.01, respectively). A significant decrease in cholesterol, triglycerides, and IGF-1 and a significant increase in pre-albumin in blood was also observed post-intervention (p < 0.05). Conclusions: This supervised, community-based 12-week multicomponent was feasible (adherence rate 70.35%) and provided benefits not only to physical performance but also to the quality of life of patients with NSCLC.

Effect of Tele-exercise Interventions on Quality of Life in Cancer Patients: A Meta-analysis

PURPOSE

To evaluate the impacts of tele-exercise intervention with cancer patients' quality of life, taking into account the influence of the duration of tele-exercise intervention, type of intervention, and gender of cancer patients on quality of life.

METHODS

The PubMed (MEDLINE), Embase, CINAHL, Cochrane Central Register of Controlled Trials (CENTRAL), Web of Science, and PsycINFO databases were searched from inception to August 21, 2023. The Cochrane Collaboration's risk of bias tool 2 was utilized to estimate the risk of bias, and the Grading of Recommendations, Assessment. For statistical analyses, R Studio was employed.

RESULTS

This meta-analysis contained eight trials. When compared to controls, tele-exercise interventions (SMD = 0.41, 95% CI: 0.12 to 0.70, p < .010; I2 = 54%, p = .030) have a positive influence on boosting the quality of life within cancer patients. Subgroup analyses demonstrated the greater effectiveness of tele-exercise in enhancing the quality of life of cancer patients when the duration was greater than or equal to 10 weeks. Furthermore, tele-exercise was found to have a stronger advantageous effect on quality of life among female cancer. In addition, among the types of interventions for tele-exercise, neither web-based nor telephone-based formats significantly enhanced quality of life among cancer patients.

CONCLUSION

Tele-exercise interventions are a cost-effective and feasible non-pharmacologic complementary way to promote cancer patients' quality of life. Additional large-sample, carefully designed randomized controlled trials are warranted to further validate the impact of tele-exercise concerning cancer patients' quality of life.

The effect of pulmonary rehabilitation on quality of life and functional capacity after chemotherapy in patients with small cell lung cancer

OBJECTIVE

This study aimed to investigate the effect of pulmonary rehabilitation on quality of life during the survival period in individuals with small cell lung cancer.

METHODS

Thirty-six patients with a diagnosis of small cell lung cancer (SCLC), who completed chemotherapy treatment and were in the survival period, were included in the study. A pulmonary rehabilitation program was applied to individuals at 40-70% of submaximal heart rate, 3 days a week for 8 weeks. The pulmonary rehabilitation program will consist of warm up, breathing exercises, gait training, aerobic exercises, and cool down exercises. Demographic information, walking distance, and presence of dyspnea were questioned. Inspiration/expiration difference was evaluated. Vital signs were evaluated before each session. Quality of life was assessed with the Cancer-Specific Developed Quality of Life Scale (EORTC-QLQ-C30).

RESULTS

Of the patients, 80% (36 people) completed the entire 8-week program. The mean age of the individuals was 51.78 ± 10.23. In the evaluation made at the end of the rehabilitation program, it was observed that the walking distance of the individuals increased significantly. Inspiration of individuals' expiratory difference increased by an average of 2.01 ± 0.40 cm. Improvement was found in the sub-parameters of quality of life (p < 0.05).

SIGNIFICANCE OF RESULTS

The participants with small cell lung cancer had decreased quality of life due to long-term immobilization, surgery, hospitalization times, side effects of chemotherapy treatment, and other problems. Regular exercise programs can provide an increase in the individual's pulmonary functions. Individual-specific pulmonary rehabilitation programs have important contributions to the quality of life in SCLC on the survival period, and it has shown that this study can guide physiotherapists and physicians working in oncological rehabilitation and pulmonary rehabilitation.

Exercise referral schemes increase Patients' cardiorespiratory Endurance: A systematic review and Meta-Analysis

Introduction

The efficacy of exercise referral schemes (ERS) involving primary care providers to an exercise specialist on patients' physical activity is uncertain and primarily based on self-report outcomes. Cardiorespiratory endurance carries clinically relevant information and is an objective outcome measure that has been used to evaluate ERS, but this literature has not been amalgamated. We determined the effectiveness of ERS involving qualified exercise professionals (QEPs) on patients' cardiorespiratory endurance.

Methods

A systematic review with between-group and within-group meta-analyses was performed to examine the effects of ERS on cardiorespiratory endurance. We searched Scopus, EMBASE, MEDLINE, CINAHL, and Academic Search Premier databases from their inception to February 2023 to find ERS interventions (randomized/non-randomized, controlled/non-controlled). To be included, studies required an adult patient referral from a primary care provider to a QEP.

Results

Twenty-nine articles comprising 6326 (3684 females) unique patients were included. Patients were primarily older (62 ± 9 years; range: 48-82) and overweight (body mass index: 28.9 ± 7.5 kg/m2; range: 22.5-37.1). Improvements in patients' cardiorespiratory endurance were observed in 20 of the 29 studies. Among controlled studies (n = 14), the meta-analysis exhibited a favorable effect on cardiorespiratory endurance between the intervention and the comparator groups (Hedge's g: 0.31, 95 % CI: 0.09 to 0.52). The ERS interventions also improved cardiorespiratory endurance when comparing pre- and post-intervention effects (all studies, Cohen's d: 0.57, 95 % CI: 0.45 to 0.69).

Conclusion

ERS that incorporate a QEP lead to improvements in patients' cardiorespiratory endurance, providing support for the creation of these programs to help patients lead healthier lifestyles.

Resiliency among older adults receiving lung cancer treatment (ROAR-LCT): A novel supportive care intervention for older adults with advanced lung cancer

INTRODUCTION

Novel supportive care interventions designed for an aging population with lung cancer are urgently needed. We aimed to determine the feasibility of a novel supportive care physical therapy (PT) plus progressive muscle relaxation (PMR) intervention delivered to older adults with advanced lung cancer in the United States (US).

MATERIALS AND METHODS

This clinical trial, Resiliency Among Older Adults Receiving Lung Cancer Treatment (ROAR-LCT: NCT04229381), recruited adults aged ≥60 years with unresectable stage III/IV non-small cell (NSCLC) or small cell lung cancer (SCLC) receiving cancer treatment at The James Thoracic Oncology Center (planned enrollment, N = 20). There were no exclusion criteria pertaining to performance status, laboratory values, prior cancer diagnoses, comorbidities, or brain metastases. Participants were evaluated by PT and psychology and given an exercise pedaler, resistance bands, a relaxation voice recording, and instructions at study initiation. Participants were evaluated in-person by PTs and psychologists at the start and end of the 12-session intervention, with the intervening sessions conducted via virtual health. Participants completed self-reported measures of functional status, symptoms, and mood longitudinally with the following instruments: EQ-5D-5L, Patient Health Questionnaire-9, and General Anxiety Disorder-7. PT assessments included the Short Physical Performance Battery (SPPB) and the two-minute walk test. Feasibility was defined as at least 60% of participants completing at least 70% of all intervention sessions. Optional gut microbiome samples and activity monitoring data (ActiGraph®) were also collected.

RESULTS

The ROAR-LCT study concluded after consenting 22 patients. Among the 22 consented, 18 (81.8%) started the intervention; 11 participants (61.1%) completed at least 70% of all study sessions. All participants with SCLC completed the intervention. Reasons for withdrawal included progression of disease or hospitalization. The majority (88.9%) of patients who started were able to complete at least one virtual health session. Participants' functional status, SPPB, depression, and anxiety scores were stable from pre- to post-intervention. Participants who withdrew had worse baseline scores across domains. Seven microbiome and six ActiGraph® samples were collected.

DISCUSSION

This is one of the first PT + PMR supportive care interventions using virtual health among older adults with advanced lung cancer to achieve feasibility in the US.

Non-pharmacological interventions targeting mobility among people with advanced cancer: a systematic review

PURPOSE

To synthesise evidence evaluating non-pharmacological interventions targeting mobility among people with advanced cancer, considering the type, efficacy and contextual factors that may influence outcome.

METHODS

Systematic review of studies of non-pharmacological interventions in adults (≥ 18 years) with advanced (stage III-IV) cancer, and assessing mobility using clinical or patient-reported outcome measures. Searches were conducted across three electronic databases (MEDLINE, EMBASE and CINAHL) up to June 2024. Methodological quality was assessed using Joanna Briggs Institute tools and contextual factors were evaluated through the Context and Implementation of Complex Interventions framework. A narrative synthesis was conducted due to clinical heterogeneity of included studies.

RESULTS

38 studies encompassing 2,464 participants were included. The most frequent mobility outcome measure was the 6-min walk test (26/38 studies). Exercise was the most common intervention, (33 studies: 27 aerobic and resistance, 5 aerobic, 1 resistance versus aerobic training) and improvements in mobility were found in 21/33 outcomes. Electrotherapy interventions led to significant improvements in mobility in 3/5 studies. Geographical factors (e.g. distance, transport, parking requirements) potentially limited participation in 18/38 studies. A lack of ethnic diversity among populations was evident and language proficiency was an inclusion criterion in 12 studies.

CONCLUSION

Exercise and neuromuscular electrical stimulation appear to improve mobility outcomes in advanced cancer. The evaluation of other non-pharmacological interventions targeting mobility should consider access and inclusivity, and be adaptable to the needs of this population.

Effect of physical activity on patients of NSCLC

OBJECTIVE

The purpose of this study is to assess the impact of physical activity on both therapeutic efficacy and immune-related adverse events (irAEs) during immunotherapy for non-small cell lung cancer (NSCLC).

METHODS

Physical activity was divided into three groups: light physical activity (LPA), moderate physical activity (MPA), and vigorous physical activity (VPA) for laboratory indexes, efficacy, and irAEs. A multivariate logistic regression was employed to analyze the relationship between sedentary behavior with efficacy and irAEs.

RESULTS

The study included 121 patients. The three levels of physical activity were not significantly associated with efficacy or irAEs. However, noteworthy disparities were observed in base-hemoglobin levels (F = 3.4, P = 0.037) and base-lymphocyte levels (χ2 = 6.13, P = 0.047) among the three groups. After treatment, we identified statistically significant variations in albumin levels (P = 0.012) and lymphocyte counts (P = 0.035). Furthermore, a negative correlation emerged between pre-treatment sedentary behavior duration and immune-efficacy (β: -0.005, P = 0.027).

CONCLUSIONS

In summary, within the cohort of NSCLC patients undergoing single immunotherapy or a combination of immunotherapy and chemotherapy, physical activity is closely related to immune and inflammatory indicators in patients, and prolonged sitting will reduce the therapeutic effect.

Associations of different combinations of moderate-vigorous physical activity and muscle-strengthening activity with mortality among US lung cancer survivors

BACKGROUND

To investigate the associations of different combinations of moderate to vigorous physical activity (MVPA) and muscle strengthening activity (MSA) with all-cause and cancer mortality among lung cancer survivors.

METHODS

This nationwide prospective cohort study used data from the US National Health Interview Survey 2009-2018. A total of 785 lung cancer survivors were included in the study. Participants were linked to the National Death Index through December 31, 2019. Self-reported MVPA and MSA frequency data were used to obtain 4 mutually exclusive exposure categories. Multivariate Cox proportional hazard models were applied to explore the association between exposure categories and outcomes.

RESULTS

The mean (standard deviation [SD]) age of the study population was 69.1 (11.3) years and 429 (54.6%) were female. Among them, 641 (81.7%) were White and 102 (13.0%) were Black. The median follow-up time was 3 years (2526 person-years), and 349 (44.5%) all-cause deaths and 232 (29.6%) cancer deaths occurred. Compared to the MVPA < 60 min/week and MSA < 2 sessions/week group, individuals in the MVPA ≥ 60 min/week and MSA < 2 sessions/week group showed hazard ratios (HRs) of 0.50 (95% CI, 0.36-0.69) for all-cause mortality and 0.37 (95% CI, 0.20-0.67) for cancer mortality after the adjustment of covariates. Those in the MVPA ≥ 60 min/week and MSA ≥ 2 sessions/week group exhibited HRs of 0.52 (95% CI, 0.35-0.77) for all-cause mortality and 0.27 (95% CI, 0.12-0.62) for cancer mortality when compared to the MVPA < 60 min/week and MSA < 2 sessions/week group. We also identified distinct non-linear relationships between MVPA and outcomes risk among two MSA frequency subgroups.

CONCLUSION

This cohort study demonstrated that higher levels of MVPA and MSA combined might be associated with optimal reductions of mortality risk in lung cancer survivors.

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.

ExPeCT: a randomised trial examining the impact of exercise on quality of life in men with metastatic prostate cancer

PURPOSE

All patients living with cancer, including those with metastatic cancer, are encouraged to be physically active. This paper examines the secondary endpoints of an aerobic exercise intervention for men with metastatic prostate cancer.

METHODS

ExPeCT (Exercise, Prostate Cancer and Circulating Tumour Cells), was a multi-centre randomised control trial with a 6-month aerobic exercise intervention arm or a standard care control arm. Exercise adherence data was collected via heart rate monitors. Quality of life (FACT-P) and physical activity (self-administered questionnaire) assessments were completed at baseline, at 3 months and at 6 months.

RESULTS

A total of 61 patients were included (69.4 ± 7.3 yr, body mass index 29.2 ± 5.8 kg/m²). The median time since diagnosis was 34 months (IQR 7-54). A total of 35 (55%) of participants had > 1 region affected by metastatic disease. No adverse events were reported by participants. There was no effect of exercise on quality of life (Cohen's d =  - 0.082). Overall adherence to the supervised sessions was 83% (329 out of 396 possible sessions attended by participants). Overall adherence to the non-supervised home exercise sessions was 72% (months 1-3) and 67% (months 3-6). Modelling results for overall physical activity scores showed no significant main effect for the group (p-value = 0.25) or for time (p-value = 0.24).

CONCLUSION

In a group of patients with a high burden of metastatic prostate cancer, a 6-month aerobic exercise intervention did not lead to change in quality of life. Further exercise studies examining the role of exercise for people living with metastatic prostate cancer are needed.

TRIAL REGISTRATION

The trial was registered at clinicaltrials.gov (NCT02453139) on May 25th 2015.

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.

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.

Prehabilitation and Rehabilitation for Patients with Lung Cancer: A Review of Where we are Today

Lung cancer is the third most common type of cancer in the UK, with nearly 50 000 new cases diagnosed a year. Treatments for lung cancer have improved in recent years with the advent of new surgical and radiotherapy techniques and the increased use of immunotherapies. These advances have resulted in increasing numbers of patients surviving beyond the completion of their treatment. Lung cancer patients are now not dying from their cancer diagnosis, but from other co-existing pathologies. Lung cancer patients commonly present with multiple comorbidities. Mitigating the effects of poor lifestyles and changing behaviours may improve the efficacy of treatments, reduce side-effects and improve the quality of life for lung cancer patients. Published evidence supports the use of interventions to manage behavioural habits, to optimise the health of patients. There is no consensus as to what, when or how to embed these into the patient pathway. Supporting patients before, during and after their cancer treatments to increase activity, eat well and stop smoking have been seen to decrease side-effects and improve patient outcomes and wellbeing. The challenge is to provide a package of interventions that is acceptable to patients and fits within the patient pathway so as not to conflict with diagnostic and therapeutic activities. This article reviews where we are today with providing behavioural support to optimise the health of lung cancer patients undergoing treatment.

Systematic assessment of microRNAs associated with lung cancer and physical exercise

It has long been evident that physical exercise reduces the risk of cancer and improves treatment efficacy in tumor patients, particularly in lung cancer (LC). Several molecular mechanisms have been reported, but the mechanisms related to microRNAs (miRNAs) are not well understood. MiRNAs modulated various basic biological processes by negatively regulating gene expression and can be transmitted between cells as signaling molecules. Recent studies have shown that miRNAs are actively released into the circulation during exercise, and are deeply involved in cancer pathology. Hence, the role of exercise intervention in LC treatment may be further understood by identifying miRNAs associated with LC and physical activity. Here, miRNAs expression datasets related to LC and exercise were collected to screen altered miRNAs. Further bioinformatic approaches were performed to analyze the value of the selected miRNAs. The results identified 42 marker miRNAs in LC, of which three core-miRNAs (has-miR-195, has-miR-26b, and has-miR-126) were co-regulated by exercise and cancer, mainly involved in cell cycle and immunity. Our study supports the idea that using exercise intervention as adjuvant therapy for LC patients. These core-miRNAs, which are down-regulated in cancer but elevated by exercise, may act as suppressors in LC and serve as non-invasive biomarkers for cancer prevention.

Effectiveness of Outpatient Pulmonary Rehabilitation in Patients with Surgically Resected Lung Cancer: A Retrospective Real-World Analysis

Patients with lung cancer frequently suffer from physical deconditioning, low exercise capacity, and reduced quality of life. There is little evidence on the effects of a structured outpatient pulmonary rehabilitation program (OPR) on exercise capacity and symptom load in these patients. We performed a retrospective, single-center analysis of surgically resected lung cancer patients, who underwent a multiprofessional 6-week OPR. The primary endpoint was a change in the six-minute walk test distance (6 MWT). Secondary endpoints included changes in maximal workload and constant work-rate test results during cycle-ergometry, upper and lower extremity strength, and inspiratory muscle strength. The COPD Assessment Test (CAT) was used to assess symptom burden. Fifty-seven patients were included. Of those, fifty-two (91.2%) completed the full 6 weeks of OPR. The mean age was 56.4 (SD 9.2) years, and 58% were female. At completion of OPR, there was a statistically significant mean of a 50 m (95% CI, 29.6−70.7; p < 0.001) increase in 6 MWT. Significant improvements were also seen in all other exercise and strength tests (p < 0.001), accompanied by a significant reduction in the CAT score (mean difference −3.1, p = 0.001). No adverse effects were reported. OPR for surgically resected lung cancer patients was safe and effective and showed high adherence in the current study.

Association between Nutritional Status and Treatment Response and Survival in Patients Treated with Immunotherapy for Lung Cancer: A Retrospective French Study

Simple Summary

It is estimated that 73% of advanced non-small cell lung cancers (NSCLC) will become malnourished and develop cachexia which is considered as an independent prognostic factor. Therefore, this study aimed to investigate the association between nutritional assessments and (i) immunotherapy efficacy, (ii) tolerance, and (iii) survival in patients with an advanced NSCLC stage of lung cancer treated with immunotherapy. In total, 67% of the 120 patients analysed were not malnourished, 20% presented with moderate malnutrition, and 13% presented with severe malnutrition. There was no significant link between the nutritional status and the toxicity of immunotherapy. However, severe malnutrition was significantly associated with treatment efficacy and with a lower survival rate. Malnutrition appears to have a negative impact in the case of immunotherapy, in contrast to a high body mass index, which seems to be protective. In addition to confirming the benefits of early and appropriate nutritional management, research must also focus on catabolism and the uncontrolled inflammatory mechanisms.

Abstract

Malnutrition is associated with a greater risk of morbidity and mortality and lower tolerance to chemotherapy. Our purpose was to study the association between nutritional status and the efficiency and tolerance of immunotherapy in non-small cell lung cancer (NSCLC). Nutritional and oncological data were reported at 2 months (M2) and 4 months (M4) after the initiation of immunotherapy (M0). The influence of nutritional status at M0 was estimated with the efficacy and toxicity of immunotherapy at M2 to M4. In total, 127 patients were included in the study, and nutritional status was estimated at M0 for 120 patients: 67% were not malnourished, 20% presented with moderate malnutrition, and 13% presented with severe malnutrition. There was no significant link between the nutritional status at M0 and the toxicity of immunotherapy at M2 and M4. However, severe malnutrition was significantly associated with treatment efficacy at M2 (p = 0.04) and with a lower survival rate with an HR (Hazard Ratio) = 2.32–95% C.I: 1.13–4.75 (p = 0.02). Furthermore, a monthly decrease of 1% of the weight had an HR = 1.17–95% C.I: 1.13–1.21 (p = 0.0001). Severe malnutrition and weight loss are independent factors associated with lower survival. Studies integrating the systemic detection of sarcopenia with a closer nutritional follow-up could highlight an improvement in survival.

Feasibility of Rehabilitation during Chemoradiotherapy among Patients with Stage III Non-Small Cell Lung Cancer: A Proof-of-Concept Study

Rehabilitation during chemoradiotherapy (CHRT) might (partly) prevent reduction in physical fitness and nutritional status and could improve treatment tolerance in patients with stage III non-small cell lung cancer (NSCLC). The aim of this proof-of-concept study was to investigate the feasibility of a multimodal program for rehabilitation during CHRT. A home-based multimodal rehabilitation program (partly supervised moderate-intensity physical exercise training and nutritional support) during CHRT was developed in collaboration with patients with stage III NSCLC and specialized healthcare professionals. A predetermined number of six patients with stage III NSCLC (aged > 50 years) who underwent CHRT and participated in this program were monitored in detail to assess its feasibility for further development and optimization of the program. The patient’s level of physical functioning (e.g., cardiopulmonary exercise test, six-minute walking test, handgrip strength, body mass index, fat free mass index, energy and protein intake) was evaluated in order to provide personalized advice regarding physical exercise training and nutrition. The program appeared feasible and well-tolerated. All six included patients managed to perform the assessments. Exercise session adherence was high in five patients and low in one patient. The performed exercise intensity was lower than prescribed for all patients. Patients were motivated to complete the home-based rehabilitation program during CHRT. Preliminary effects on physical and nutritional parameters revealed relatively stable values throughout CHRT, with inter-individual variation. Supervised and personalized rehabilitation in patients with stage III NSCLC undergoing CHRT seems feasible when the intensity of the physical exercise training was adjusted to the possibilities and preferences of the patients. Future research should investigate the feasibility of a supervised and personalized rehabilitation program during CHRT with a low-to-moderate exercise intensity with the aim to prevent physical decline during CHRT.

Perioperative exercise intervention in patients with lung cancer: A systematic literature review of randomized controlled trials

Objectives:

During perioperative, lung cancer (LC) patients are often left to experience debilitating disease-related symptoms, impaired physical activity and health-related quality of life (HRQoL), and social difficulties, despite the progress achieved in terms of treatment efficacy. Nonpharmacological intervention, such as exercise, has been identified as an effective strategy in LC patients before and after lung resection. Therefore, we aimed to assess evidence of the effect of perioperative exercise among patients with LC.

Materials and Methods:

Seven databases were searched from January 1998 to September 2020. All randomized controlled trials (RCTs) that evaluated the effect of exercise on the physical and psychological status of patients with LC during the perioperative period were reviewed. Two reviewers independently assessed the quality of all studies included here using the revised Cochrane risk of bias tool for RCTs.

Results:

Seventeen RCTs (1199 participants) published between 2011 and 2019 met for this literature review. The outcome measures that emerged from these studies included subjective outcomes, such as HRQoL, pain score, fatigue, and objective effects, such as cardiorespiratory fitness, pulmonary function, physical activity, and biological markers. Overall, these studies suggest that exercise should be an optimal option for LC; however, its efficacy and effectiveness regarding HRQoL should be investigated further.

Conclusion:

Perioperative exercise could be included in the rehabilitation program of patients with LC. More extensive, high-quality RCTs evidence is needed on the ideal exercise type, duration, intensity, and timing across the LC perioperative care.

Lifestyle considerations in multiple myeloma

As the prognosis for multiple myeloma (MM) has significantly improved and patients remain on therapy longer, there is a need for supportive care interventions to optimize patient quality of life (QOL) and functional status over the course of cancer treatment. MM is characterized by a significant symptom burden and a relatively lower QOL compared to other cancers. This review evaluates the role of healthy lifestyle behaviors in improving both the physical functioning and psychological well-being of the MM population. We (1) describe the current literature on physical activity, weight management, diet, sleep, and substance use in the context of MM, (2) present important considerations for incorporating lifestyle factors into clinical practice, and (3) identify directions for future research. Developing MM-specific guidelines for modifiable lifestyle changes that take into account both the length of treatment and the unique disease features (i.e. osteolytic lesions and anemia) may provide a promising path for improved patient QOL and functioning.

Short-Term Changes in Quality of Life in Patients with Advanced Lung Cancer during In-Hospital Exercise Training and Chemotherapy Treatment: A Randomized Controlled Trial

The aim of this study was to assess the impact of exercise training on the quality of life (QoL) of patients diagnosed with stage IIIB and stage IV non–small cell lung cancer (NSCLC) compared to a passive control group (CG). The exercise-trained group (ETG) consisted of 18 patients, and the CG consisted of 8 patients. The training program in the ETG consisted of two 2-week running cycles interspersed with consecutive rounds of chemotherapy with cytostatic drugs. A comparison of the changes in the Short Form (36) Health Survey (SF-36), St. George’s Respiratory Questionnaire (SGRQ), and the Functional Assessment of Cancer Therapy-Lung (FACT-L) was the primary outcome. Analysis of the results of the SGRQ and the SF-36 questionnaire did not reveal any statistically significant differences in the assessment of QoL between the examined groups. The analysis of FACT-L questionnaires showed statistically significant changes, indicating deterioration of QoL in domains describing physical well-being in the CG. Therefore, the analysis of the results of the QoL assessment did not show any significant improvements in the group of patients undergoing comprehensive exercise training, although deterioration of QoL was noted in the CG.

Feasibility of a multimodal exercise, nutrition, and palliative care intervention in advanced lung cancer

BACKGROUND

Advanced lung cancer patients face significant physical and psychological burden leading to reduced physical function and quality of life. Separately, physical activity, nutrition, and palliative symptom management interventions have been shown to improve functioning in this population, however no study has combined all three in a multimodal intervention. Therefore, we assessed the feasibility of a multimodal physical activity, nutrition, and palliative symptom management intervention in advanced lung cancer.

METHODS

Participants received an individually tailored 12-week intervention featuring in-person group-based exercise classes, at-home physical activity prescription, behaviour change education, and nutrition and palliative care consultations. Patients reported symptom burden, energy, and fatigue before and after each class. At baseline and post-intervention, symptom burden, quality of life, fatigue, physical activity, dietary intake, and physical function were assessed. Post-intervention interviews examined participant perspectives.

RESULTS

The multimodal program was feasible, with 44% (10/23) recruitment, 75% (75/100) class attendance, 89% (8/9) nutrition and palliative consult attendance, and 85% (17/20) assessment completion. Of ten participants, 70% (7/10) completed the post-intervention follow-up. Participants perceived the intervention as feasible and valuable. Physical activity, symptom burden, and quality of life were maintained, while tiredness decreased significantly. Exercise classes prompted acute clinically meaningful reductions in fatigue, tiredness, depression, pain, and increases in energy and well-being.

CONCLUSION

A multimodal physical activity, nutrition, and palliative symptom management intervention is feasible and shows potential benefits on quality of life that warrant further investigation in a larger cohort trial.

Feasibility of Aerobic Exercise and Tai-Chi Interventions in Advanced Lung Cancer Patients: A Randomized Controlled Trial

BACKGROUND

A majority of lung cancer patients are diagnosed at advanced stages. Although there is considerable evidence of the benefits of aerobic exercise and tai-chi for lung cancer patients, little is known about the comparative effectiveness of the 2 exercise modes in advanced lung cancer patients.

OBJECTIVES

To explore the feasibility and preliminary effects of aerobic exercise and tai-chi interventions on survival and well-being among advanced lung cancer patients.

METHODS

In an assessor-blinded, exploratory randomized controlled trial, 30 advanced lung cancer patients were randomized to an aerobic exercise group, a tai-chi group (both attending 12-week, twice-weekly supervised sessions), or a self-management control group (receiving written exercise guidelines). The primary outcomes focused on feasibility including intervention completion, exercise adherence, and adverse events, while the secondary outcomes addressed preliminary effects and included 1-year survival, cancer symptoms (Pittsburgh Sleep Quality Index, Hospital Anxiety and Depression Score, Brief Fatigue Inventory), quality of life (EORTC QLQ-C30, QLQ-LC13), physical performance (6-minute walk test, up-and-go, sit-to-stand, 1-leg standing), activity levels (actigraph), and circadian rhythms (salivary cortisol).

RESULTS

Intervention feasibility was established with a satisfactory completion rate at post-intervention for the aerobic exercise group (80%) and the tai-chi group (78%). The tai-chi group attained higher adherence than the exercise group in terms of attendance in supervised sessions (89% vs 75% of scheduled classes) and self-practice (225% vs 87% of the prescribed amount). Higher adherence to self-practice in the tai-chi group remained at the 6-month follow-up (81% vs 38% of the prescribed amount). No adverse event as a result of the intervention was reported. Effect-related outcomes did not show statistically significant changes in any group, except an improvement post-intervention in the up-and-go (-2.26, 95% CI: -4.04, -0.48) and sit-to-stand tests (4.52, 95% CI: 2.19, 6.85) in the aerobic exercise group.

CONCLUSIONS

The findings support the feasibility of aerobic exercise and tai-chi interventions in advanced lung cancer patients. A future study with a larger sample from multiple sites is recommended to confirm the comparative effects of the 2 exercise interventions relative to the self-management group and to enhance the generalizability of the findings.

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.

Feasibility of setting up a pre-operative optimisation 'pre-hab' service for lung cancer surgery in the UK

Pre-operative optimisation ‘pre-hab’ is a growing area in peri-operative medicine. This is usually undertaken with the aim of reducing post-operative complications. In the case of early-stage lung cancer, surgery is the treatment modality with the best-proven cure rates. With this in mind, we set up a pre-hab service, not merely to reduce the risk of post-operative complications, but to enable patients of borderline fitness for surgery to safely undergo this potentially lifesaving treatment. We believe this service to be one of the first of its kind in the UK, here we describe the challenges we faced in setting it up and the outcomes from our first 50 patients.

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.

Effect of Collaborative Telerehabilitation on Functional Impairment and Pain Among Patients With Advanced-Stage Cancer: A Randomized Clinical Trial

Importance

Most patients with advanced-stage cancer develop impairment and pain-driven functional losses that jeopardize their independence.

Objective

To determine whether collaborative telerehabilitation and pharmacological pain management improve function, lessen pain, and reduce requirements for inpatient care.

Design, Setting, and Patients

The Collaborative Care to Preserve Performance in Cancer (COPE) study was a 3-arm randomized clinical trial conducted at 3 academic medical centers within 1 health care system. Patient recruitment began in March 2013 and follow-up concluded in October 2016. Participants (N = 516) were low-level community or household ambulators with stage IIIC or IV solid or hematologic cancer.

Interventions

Participants were randomly assigned to the (1) control arm, (2) telerehabilitation arm, or (3) telerehabilitation with pharmacological pain management arm. All patients underwent automated function and pain monitoring with data reporting to their care teams. Participants in arms 2 and 3 received 6 months of centralized telerehabilitation provided by a physical therapist-physician team. Those in arm 3 also received nurse-coordinated pharmacological pain management.

Main Outcomes and Measures

Blinded assessment of function using the Activity Measure for Postacute Care computer adaptive test, pain interference and average intensity using the Brief Pain Inventory, and quality of life using the EQ-5D-3L was performed at baseline and months 3 and 6. Hospitalizations and discharges to postacute care facilities were recorded.

Results

The study included 516 participants (257 women and 259 men; mean [SD] age, 65.6 [11.1] years), with 172 randomized to 1 of 3 arms. Compared with the control group, the telerehabilitation arm 2 had improved function (difference, 1.3; 95% CI, 0.08-2.35; P = .03) and quality of life (difference, 0.04; 95% CI, 0.004-0.071; P = .01), while both telerehabilitation arms 2 and 3 had reduced pain interference (arm 2, -0.4; 95% CI, -0.78 to -0.09; P = .01 and arm 3, -0.4; 95% CI, -0.79 to -0.10; P = .01), and average intensity (arm 2, -0.4; 95% CI, -0.78 to -0.07; P = .02 and arm 3, -0.5; 95% CI, -0.84 to -0.11; P = .006). Telerehabilitation was associated with higher odds of home discharge in arms 2 (odds ratio [OR], 4.3; 95% CI, 1.3-14.3; P = .02) and 3 (OR, 3.8; 95% CI, 1.1-12.4; P = .03) and fewer days in the hospital in arm 2 (difference, -3.9 days; 95% CI, -2.4 to -4.6; P = .01).

Conclusions and Relevance

Collaborative telerehabilitation modestly improved function and pain, while decreasing hospital length of stay and the requirement for postacute care, but these outcomes were not enhanced with the addition of pharmacological pain management.

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.

Emerging Treatment Options For Cancer-Associated Cachexia: A Literature Review

Cachexia is a disease that has been recognized since antiquity; however, research in this area has recently increased. Promising new agents, including anamorelin hydrochloride, have been tested in large randomized controlled studies, and multidrug as well as multimodal approaches have been proposed as having the potential to improve outcomes in patients with cancer cachexia. However, standard treatment remains elusive. This review summarizes the current literature on treatment of cancer-associated cachexia, showing that there are challenges associated with conducting clinical trials in such patients. First, poor recruitment, retention, and compliance among cachectic patients cause research delays. Second, the lack of consensus regarding clinically meaningful endpoints impedes standardization of study designs and results. Further consideration is needed to identify the most suitable study design and endpoints, which can lead to the development of pharmacological and nonpharmacological interventions that improve patients’ prognosis and outcomes.

Muscle protein anabolism in advanced cancer patients: response to protein and amino acids support, and to physical activity

In the field of oncology, it is well recognized that a decrease in mass, density, strength, or function of skeletal muscle is associated to increased treatment toxicities and postoperative complications, as well as poor progression-free survival and overall survival. The ability of amino acids to stimulate protein synthesis in cancer patients is reduced. Considering nutritional intervention, this anabolic resistance could be in a part counteracted by increasing protein or by giving specific amino acids. In particular, Leucine might counteract this anabolic resistance not only by increasing substrate availability, but also by directly modulating the anabolic signal pathway. Few studies showed the possibility of increasing muscle protein synthesis by specific nutriments and/or by increasing amino acids or protein administration. In addition, whereas many studies provide evidence of a benefit of adapted physical activity in advanced cancer patients, it is difficult to specify the most appropriate type of exercise, and the optimum rhythm and intensity. Moreover, the benefits of physical activities and of protein support seem greater when it is started at the precachexia stage rather than at the cachexia stage, and their benefits are limited or nonexistent at the stage of refractory cachexia. Future approaches should integrate the combination of several complementary treatments in order to prevent (or improve) cachexia and/or sarcopenia in cancer patients.

Exercise interventions for patients with advanced cancer: A systematic review of recruitment, attrition, and exercise adherence rates

Purpose

Patients with advanced cancer can experience debilitating physical symptoms, making participation in exercise programs difficult. This systematic review investigated the recruitment, adherence, and attrition rates of patients with advanced cancer participating in exercise interventions and examined components of exercise programs that may affect these rates.

Methods

Relevant studies were identified in a systematic search of CINAHL, PubMed, PsycINFO, and EMBASE to December 2017. Two quality assessment tools were used, and levels of evidence were assigned according to the Oxford Centre for Evidence-Based Medicine (CEBM) guidelines.

Results

The search identified 18 studies published between 2004 and 2017. Recruitment, adherence, and attrition rates varied widely among the studies reviewed. The mean recruitment rate was 49% (standard deviation [SD] = 17; range 15–74%). Patient-reported barriers to recruitment included time constraints and difficulties in traveling to exercise centers. Levels of adherence ranged from 44% to 95%; however, the definition of adherence varied substantially among trials. The average attrition rate was 24% (SD = 8; range 10–42%), with progression of disease status reported as the main cause for dropout during exercise interventions.

Significance of results

Concentrated efforts are needed to increase the numbers of patients with advanced disease recruited to exercise programs. Broadening the eligibility criteria for exercise interventions may improve accrual numbers of patients with advanced cancer to exercise trials and ensure patients recruited are representative of clinical practice.

Effects of combined supervised intermittent aerobic, muscle strength and home-based walking training programs on cardiorespiratory responses in women with breast cancer

BACKGROUND

The aim of this investigation was to study the effects of supervised combined intermittent aerobic, muscle strength and home-based walking training programs on cardiorespiratory fitness in women with breast cancer during adjuvant chemotherapy treatment.

METHODS

Thirty-two women with breast cancer undertaking adjuvant chemotherapy participated in the study (trained group n=20 and control group n=12). The trained group carried out 6weeks of supervised intermittent cycling aerobic, muscle strength and home-based walking training programs. The self-selected walking speed (WS), walking distance covered (WD), heart rate (rHR), blood lactate ([La]b) concentration and rating of perceived exertion (RPE) were assessed in the two groups during the 6-min walking test before and after the training period.

RESULTS

Compared to controls, a significant increase in the WS (P<0.01) and the WD (P<0.01) accompanied by a significant decrease in resting rHR (P<0.01), exercising HR6' (P<0.01), [La]b (P<0.05), HR6'/WS (P<0.01) and [La]b/WS ratios (P<0.01) was reported in the trained group. However, a significant decrease both in WD (P<0.01) and WS (P<0.01) has been observed in the controls. No significant difference was observed in resting HR, exercising HR6', [La]b, HR6'/WS, and [La]b/WS ratios were observed in the control group. A significant improvement was observed for RPE in training group (P<0.05). However, no difference was shown in controls.

CONCLUSION

Combined training based on intermittent aerobic exercise, muscle strength and walking improve cardiorespiratory responses and reduce the perception of fatigue in women with breast cancer.

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.

Exercise training for advanced lung cancer

BACKGROUND

Patients with advanced lung cancer have a high symptom burden, which is often complicated by coexisting conditions. These issues, combined with the indirect effects of cancer treatment, can cumulatively lead patients to continued deconditioning and low exercise capacity. This is a concern as exercise capacity is considered a measure of whole body health, and is critical in a patient's ability to participate in life activities and tolerate difficult treatments. There is evidence that exercise training improves exercise capacity and other outcomes, such as muscle force and health-related quality of life (HRQoL), in cancer survivors. However, the effectiveness of exercise training on these outcomes in people with advanced lung cancer is currently unclear.

OBJECTIVES

The primary aim of this review was to investigate the effects of exercise training on exercise capacity in adults with advanced lung cancer. Exercise capacity was defined as the six-minute walk distance (6MWD; in meters) measured during a six-minute walk test (6MWT; i.e. how far an individual can walk in six minutes on a flat course), or the peak oxygen uptake (i.e. VO₂peak) measured during a maximal incremental cardiopulmonary exercise test (CPET).The secondary aims were to determine the effects of exercise training on the force-generating capacity of peripheral muscles, disease-specific global HRQoL, physical functioning component of HRQoL, dyspnoea, fatigue, feelings of anxiety and depression, lung function, level of physical activity, adverse events, performance status, body weight and overall survival in adults with advanced lung cancer.

SEARCH METHODS

We searched CENTRAL, MEDLINE (via PubMed), Embase (via Ovid), CINAHL, SPORTDiscus, PEDro, and SciELO on 7 July 2018.

SELECTION CRITERIA

We included randomised controlled trials (RCTs) which compared exercise training versus no exercise training in adults with advanced lung cancer.

DATA COLLECTION AND ANALYSIS

Two review authors independently screened the studies and selected those for inclusion. We performed meta-analyses for the following outcomes: exercise capacity, disease-specific global HRQoL, physical functioning HRQoL, dyspnoea, fatigue, feelings of anxiety and depression, and lung function (forced expiratory volume in one second (FEV1)). Two studies reported force-generating capacity of peripheral muscles, and we presented the results narratively. Limited data were available for level of physical activity, adverse events, performance status, body weight and overall survival.

MAIN RESULTS

We identified six RCTs, involving 221 participants. The mean age of participants ranged from 59 to 70 years; the sample size ranged from 20 to 111 participants. Overall, we found that the risk of bias in the included studies was high, and the quality of evidence for all outcomes was low.Pooled data from four studies demonstrated that, on completion of the intervention period, exercise capacity (6MWD) was significantly higher in the intervention group than the control group (mean difference (MD) 63.33 m; 95% confidence interval (CI) 3.70 to 122.96). On completion of the intervention period, disease-specific global HRQoL was significantly better in the intervention group compared to the control group (standardised mean difference (SMD) 0.51; 95% CI 0.08 to 0.93). There was no significant difference between the intervention and control groups in physical functioning HRQoL (SMD 0.11; 95% CI -0.36 to 0.58), dyspnoea (SMD -0.27; 95% CI -0.64 to 0.10), fatigue (SMD 0.03; 95% CI -0.51 to 0.58), feelings of anxiety (MD -1.21 units on Hospital Anxiety and Depression Scale; 95% CI -5.88 to 3.45) and depression (SMD -1.26; 95% CI -4.68 to 2.17), and FEV1 (SMD 0.43; 95% CI -0.11 to 0.97).

AUTHORS' CONCLUSIONS

Exercise training may improve or avoid the decline in exercise capacity and disease-specific global HRQoL for adults with advanced lung cancer. We found no significant effects of exercise training on dyspnoea, fatigue, feelings of anxiety and depression, or lung function. The findings of this review should be viewed with caution because of the heterogeneity between studies, the small sample sizes, and the high risk of bias of included studies. Larger, high-quality RCTs are needed to confirm and expand knowledge on the effects of exercise training in this population.

Mobile Phone App-Based Pulmonary Rehabilitation for Chemotherapy-Treated Patients With Advanced Lung Cancer: Pilot Study

BACKGROUND

Advanced lung cancer patients often have chronic lung disease with reduced exercise capacities and various symptoms leading to altered quality of life (QoL). No studies have assessed pulmonary rehabilitation (PR) employing a mobile app and an Internet of Things device in advanced lung cancer patients undergoing chemotherapy.

OBJECTIVE

This study aimed to determine the feasibility and efficacy of smartphone app-based PR on exercise capacity, symptom management, and QoL in patients with advanced lung cancer undergoing chemotherapy.

METHODS

A total of 100 patients were recruited in a prospective, single-arm intervention study using a smartphone app-based PR program for 12 weeks. Exercise capacity (6-min walking distance, 6MWD), QoL, symptom scale scores, and distress indexes were investigated.

RESULTS

A total of 90 patients completed the PR program. The most common cause of drop out was hospitalization because of cancer progression. After PR, there was significant improvement in the 6MWD; 380.1 m (SD 74.1) at baseline, 429.1 m (SD 58.6) at 6 weeks (P<.001), and 448.1 m (SD 50.0) at 12 weeks (P<.001). However, the dyspnea scale score showed no significant improvement in the patients overall, but there was a trend for improvement in those with a stable tumor response (P=.07). Role (P=.02), emotional (P<.001), and social functioning (P=.002) scale scores showed significant improvement after PR. Symptom scale scores for fatigue (P<.001), anorexia (P=.047), and diarrhea (P=.01) also showed significant improvement. There was significant improvement in depression (P=.048) and anxiety (P=.01), whereas there was no significant change in QoL (P=.06) and severity of pain (P=.24).

CONCLUSIONS

Smartphone app-based PR represents an effective and feasible program to improve exercise capacity and to manage symptoms and distress in patients with advanced lung cancer who are undergoing chemotherapy.

Feasibility of early multimodal interventions for elderly patients with advanced pancreatic and non-small-cell lung cancer

BACKGROUND

Combinations of exercise and nutritional interventions might improve the functional prognosis for cachectic cancer patients. However, high attrition and poor compliance with interventions limit their efficacy. We aimed to test the feasibility of the early induction of new multimodal interventions specific for elderly patients with advanced cancer Nutrition and Exercise Treatment for Advanced Cancer (NEXTAC) programme.

METHODS

This was a multicentre prospective single-arm study. We recruited 30 of 46 screened patients aged ≥70 years scheduled to receive first-line chemotherapy for newly diagnosed, advanced pancreatic, or non-small-cell lung cancer. Physical activity was measured using pedometers/accelerometer (Lifecorder^® , Suzuken Co., Ltd., Japan). An 8 week educational intervention comprised three exercise and three nutritional sessions. The exercise interventions combined home-based low-intensity resistance training and counselling to promote physical activity. Nutritional interventions included standard nutritional counselling and instruction on how to manage symptoms that interfere with patient's appetite and oral intake. Supplements rich in branched-chain amino acids (Inner Power^® , Otsuka Pharmaceutical Co., Ltd., Japan) were provided. The primary endpoint of the study was feasibility, which was defined as the proportion of patients attending ≥4 of six sessions. Secondary endpoints included compliance and safety.

RESULTS

The median patient age was 75 years (range, 70-84). Twelve patients (40%) were cachectic at baseline. Twenty-nine patients attended ≥4 of the six planned sessions (96.7%, 95% confidence interval, 83.3 to 99.4). One patient dropped out due to deteriorating health status. The median proportion of days of compliance with supplement consumption and exercise performance were 99% and 91%, respectively. Adverse events possibly related to the NEXTAC programme were observed in five patients and included muscle pain (Grade 1 in two patients), arthralgia (Grade 1 in one patient), dyspnoea on exertion (Grade 1 in one patient), and plantar aponeurositis (Grade 1 in one patient).

CONCLUSIONS

The early induction of multimodal interventions showed excellent compliance and safety in elderly patients with newly diagnosed pancreatic and non-small-cell lung cancer receiving concurrent chemotherapy. We are now conducting a randomized phase II study to measure the impact of these interventions on functional prognosis.

Enhancing behavioral change among lung cancer survivors participating in a lifestyle risk reduction intervention: a qualitative study

PURPOSE

Early detection and improved treatment have increased lung cancer survival. Lung cancer survivors have more symptom distress and lower function compared with other cancer survivors; however, few interventions are available to improve health-related quality of life (HR-QOL). Lifestyle risk reduction interventions have improved HR-QOL in other cancer survivors. The purpose of this study was to explore lung cancer survivor perspectives on making behavioral changes in the context of a lifestyle risk reduction intervention.

METHODS

Twenty-two lung cancer survivors participated in interviews after completing the Healthy Directions (HD) intervention. Interviews were audiotaped, transcribed, and analyzed using inductive content analysis. Demographic and clinical characteristics were gathered through a survey and analyzed using descriptive statistics.

RESULTS

Five main themes were identified: (1) the diagnosis was a motivator for behavior change, (2) participants had to deal with disease consequences, (3) the coach provided guidance, (4) strategies for change were initiated, and (5) social support sustained behavioral changes. Other important subthemes were the coach helped interpret symptoms, which supported self-efficacy and goal setting, and survivors employed self-monitoring behaviors. Several participants found the recommended goals for physical activity were difficult and were discouraged if unable to attain the goal. Findings underscore the need for individualized prescriptions of physical activity, especially for sedentary survivors.

CONCLUSIONS

Lung cancer survivors described the benefits of coaching to enhance their engagement in behavioral change. Additional research is needed to validate the benefit of the HD intervention to improve HR-QOL among this vulnerable and understudied group of cancer survivors.
