Association between physical activity and patient-reported outcome measures in patients with lung cancer: a systematic review and meta-analysis

Global research and emerging trends in depression in lung cancer: a bibliometric and visualized study from 2014 to 2024

Background

The impact of depression on the physical and psychological well-being of lung cancer patients has raised significant concerns. This study explored lung cancer-related depression research from a bibliometric perspective.

Methods

Articles and reviews on depression in lung cancer published from 2014 to 2024 in the Web of Science Core Collection were retrieved and identified. The information extracted included "Full Record and Cited References". Bibliometric analysis was conducted using CiteSpace and Excel to examine relevant publications in terms of country, institution, authorship, journal, citations, and keywords.

Results

A total of 761 publications on depression in lung cancer were identified for analysis, contributed by 4,667 authors from 305 institutions and 58 countries. The annual publication count has steadily increased, culminating in a peak in 2024. China (275 papers), Harvard University (58 publications), and Joseph A. Greer (25 publications) were the most productive and influential country, institution, and author, respectively. Jennifer S. Temel emerges as a highly influential author, securing the second position in terms of both publication count and citation impact. The journal with the highest number of publications is Supportive care in cancer, while the Journal of Clinical Oncology has garnered the most citations. Reference and keyword analysis indicated that the research hotspots mainly included 1) Epidemiology of lung cancer-related depression; 2) The deleterious impact of depression on lung cancer patients, particularly with regards to their quality of life; 3) Association between inflammation and depression in lung cancer; 4) Treatment.

Conclusions

Our study employed bibliometric analysis to identify prevalent focal areas and emerging trends in the field of research on lung cancer-related depression. Our study found that numerous unanswered questions persist, including the intricate relationship between lung cancer and depression, the profound impact of depression on lung cancer patients, and the interplay between inflammation and depression in this specific population. Furthermore, a current challenge in clinical practice involves the development of secure and more efficacious treatment strategies for individuals with lung cancer-related depression. These findings provide valuable guidance for scholars seeking to explore new avenues of investigation.

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.

The association between physical activity levels and quality of life in elderly lung cancer patients undergoing chemotherapy in China: a cross-sectional study

OBJECTIVE

This study aimed to investigate the association between physical activity (PA) levels and quality of life (QOL) in elderly lung cancer patients undergoing chemotherapy in China.

METHODS

Two hundred eight elderly lung cancer patients undergoing chemotherapy were recruited by convenient sampling at two tertiary A hospitals in Guangxi from October 2023 to March 2024. The evaluation of PA Levels by the International Physical Activity Questionnaire Short Form (IPAQ-SF) was conducted, and the Functional Assessment of Cancer Therapy-Lung (FACT-L) was utilized to measure the QOL. Multiple linear regression was used to identify factors correlated with QOL.

RESULTS

Out of 208 elderly patients with lung cancer who were undergoing chemotherapy, 119 (57.20%) had low-level PA, 79 (38.00%) had moderate-level PA, and 10 (4.80%) had high-level PA. The mean score of FACT-L was 95.41 ± 15.01, and FACT-L was correlated with age, residency, education level, and per capita monthly household income (P < 0.05). Moderate to high PA levels explained 19.4% of the variation in QOL among elderly patients undergoing chemotherapy for lung cancer.

CONCLUSION

Elderly lung cancer patients undergoing chemotherapy exhibited lower levels of PA. The increase in PA levels was associated with better QOL. Treatment options for elderly lung cancer patients undergoing chemotherapy may involve PA plans to boost their QOL. It is vital to evaluate the patient's physical condition and functional level when creating these plans to ensure safety and effectiveness, thereby increasing patient engagement and maximizing enhancements in their QOL.

Associations of physical activity and sedentary time with health-related quality of life in patients with localized renal cell cancer: a cross-sectional analysis within the ReLife study

PURPOSE

This study examined the associations of device-measured moderate-to-vigorous physical activity (MVPA) and sedentary time as well as self-reported MVPA with health-related quality of life (HRQoL) in patients with localized renal cell cancer (RCC) in the recovery phase after surgery.

METHODS

At 3 months post-surgery, 341 patients with stage I-III RCC participating in the ReLife study wore an ActivPAL3 device to determine MVPA and sedentary time. The SQUASH questionnaire was used for assessing self-reported MVPA, and the EORTC QLQ-C30 for assessing HRQoL (range 0-100). Multivariable linear regression models were used to examine the cross-sectional associations of MVPA and sedentary time with HRQoL.

RESULTS

The highest (≥ 6.7 h/week) versus lowest (≤ 2.7 h/week) quartile of MVPA was associated with a better global health status (β, 10.2; 95% CI, 5.1, 15.3), summary score (β, 4.6; 95% CI, 1.1, 8.1), physical (β, 7.7; 95% CI, 3.8, 11.6), role (β, 12.4; 95% CI, 4.7, 20.2), and social functioning (β, 7.3; 95% CI, 0.2, 14.4), and lower fatigue (β, - 11.2; 95% CI, - 18.1, - 4.2). Results for self-reported MVPA were in the same direction but weaker. The lowest (≤ 8.8 h/day) versus highest (≥ 11.5 h/day) quartile of sedentary time was associated with better physical functioning (β, 4.6; 95% CI, 0.8, 8.5).

CONCLUSIONS

In patients with localized RCC, higher MVPA 3 months post-surgery was associated with better HRQoL outcomes including less fatigue whereas lower sedentary time was only associated with better physical functioning. This information can contribute to the development of physical activity guidelines and interventions to improve HRQoL.

The Physical Activity and Cancer Control (PACC) framework: update on the evidence, guidelines, and future research priorities

BACKGROUND

We proposed the Physical Activity and Cancer Control (PACC) framework in 2007 to help organise, focus, and stimulate research on physical activity in eight cancer control categories: prevention, detection, treatment preparation/coping, treatment coping/effectiveness, recovery/rehabilitation, disease prevention/health promotion, palliation, and survival.

METHODS

This perspective paper provides a high-level overview of the scientific advances in physical activity research across cancer control categories, summarises current guidelines, updates the PACC framework, identifies remaining and emerging knowledge gaps, and provides future research directions.

RESULTS

Many scientific advances have been made that are reflected in updated physical activity guidelines for six of the cancer control categories apart from detection and palliation. Nevertheless, the minimal and optimal type, dose, and timing of physical activity across cancer control categories remain unknown, especially for the understudied population subgroups defined by cancer type, age, race/ethnicity, and resource level of regions/countries.

CONCLUSION

To achieve the full benefit of physical activity in cancer control, future research should use innovative study designs that include diverse at-risk populations and understudied cancer sites. Additionally, effective behaviour change strategies are needed to increase physical activity levels across populations that use implementation science to accelerate the translation from evidence generation into practical, real-world interventions.

Exploring factors associated with postoperative physical activity and sedentary behavior in newly diagnosed lung cancer patients: a cross-sectional study

PURPOSE

To comprehensively analyze the factors associated with different intensities of physical activity and sedentary behavior in newly diagnosed lung cancer patients in the early postoperative period, providing a basis for clinically tailored personalized intervention measures.

METHODS

A cross-sectional study design was employed, and 915 patients newly diagnosed with lung cancer completed a questionnaire survey on demographics, disease, health-related fitness, and psychosocial factors. Physical activity levels and sedentary behaviors were assessed using the International Physical Activity Questionnaire. Data were analyzed using SPSS 25.0.

RESULTS

The physical activity level of walking amounted to 1265.4 ± 1025.8 MET-min/week, potentially influenced by factors such as region, depression, health behavior capacity, and lactate dehydrogenase. The moderate-intensity physical activity level stood at 529.8 ± 976.5 MET-min/week, subject to influences like regional lymph node staging, body mass index, and albumin levels, among other factors. The high-intensity physical activity level was 111.1 ± 731.0 MET-min/week, potentially affected by region, grip strength, health behavior capacity, and other factors. Sedentary time averaged 5 ± 3 h/day, potentially influenced by work conditions, red blood cell values, and other factors.

CONCLUSION

In patients newly diagnosed with lung cancer, early postoperative walking activities predominate, with less engagement in high-intensity physical activity and prolonged sedentary time. Physical activity and sedentary behavior may be influenced by various factors such as geography, physiology, psychology, and health-related fitness. To enhance the quality of life of patients with lung cancer in the early postoperative period, tailored intervention measures should be devised based on the circumstances of the individual patients.

Moderating Effect of Daylight Exposure on the Relationship Between Physical Activity and Sleep in Patients with Upper Digestive Cancer: An Exploratory Study

OBJECTIVES

To examine the moderating effect of daylight exposure on physical activity and objective sleep quality, using wearable actigraph devices.

METHODS

We recruited 324 patients with either gastric or esophageal cancer. Actigraphs were used to measure all objective data including daylight exposure, physical activity, and sleep quality. Pearson's correlation coefficients were used to examine the relationships among demographic data, disease attributes, physical activity, daylight exposure, and sleep. The Hayes PROCESS macro with the regression bootstrapping method was employed to analyze the moderating effect of daylight exposure on the relationship between physical activity and sleep.

RESULTS

Sleep efficiency correlated positively with physical activity, while "wake after sleep onset" correlated negatively with physical activity and mean lux. Mean lux and light >500 lux significantly moderated the association between physical activity and sleep efficiency (P = .002 in both cases). Similarly, mean lux and light >500 lux significantly moderated the association between physical activity and "wake after sleep onset" (P = .002 and .001, respectively).

CONCLUSION

Both average daylight exposure and time of exposure to >500 lux act as moderators of physical activity and objective sleep quality in patients with gastric or esophageal cancer. Healthcare practitioners should encourage patients with cancer to engage in daily outdoor physical activity. Further intervention studies are needed to verify the combined effect of daytime light exposure and physical activity on improving sleep quality.

IMPLICATIONS FOR NURSING PRACTICE

Healthcare practitioners should encourage patients with cancer to engage in daily outdoor physical activity. Further intervention studies are needed to verify the combined effect of daytime light exposure and physical activity on improving sleep quality.

Relationship between nausea and vomiting and physical activity in patients with lung cancer undergoing first chemotherapy

Objective

Nausea and vomiting are the distressing and debilitating side effects of chemotherapy. This study explores the relationship between the degree of nausea and vomiting and physical activity in patients with lung cancer during the first chemotherapy cycle.

Design

A total of 107 patients with lung cancer who received platinum drugs during chemotherapy in a hospital in Shanghai, China, in 2023 were involved in this study. Data were collected with medical record system and self-reported questionnaires.Questionnaires included the International Physical Activity Questionnaire (IPAQ) and Index of Nausea, Vomiting, and Retching (INVR). IPAQ was used before chemotherapy; INVR was used on the second and sixth day of chemotherapy, followed by the analysis of the correlation between physical activity status and degree of nausea and vomiting during chemotherapy. The influencing factors of nausea and vomiting during chemotherapy in patients with lung cancer were analyzed using logistic regression analysis.

Results

More than half of the patients experienced nausea, vomiting or retching related symptoms after chemotherapy, and the proportion of moderate to high physical activity was 50.5%. Univariate analysis showed that the degree of nausea and vomiting was influenced by factors such as age, gender, and history of drinking (P < 0.05). The degree of nausea and vomiting was negatively correlated with physical activity (P < 0.05). The multivariate linear analysis showed that gender, history of drinking, and moderate and high physical activity are contributing factors to nausea and vomiting during chemotherapy (P < 0.05).

Conclusion

Moderate and high physical activity before chemotherapy is a protective factor for nausea and vomiting in patients with lung cancer. Physical activity can not only improve the degree of nausea and vomiting in patients with lung cancer but also reduce the incidence in these patients during the first chemotherapy cycle.

Social support, health behavior self-efficacy, and anxiety on physical activity levels among lung cancer survivors: a structural equation modeling

PURPOSE

The study aims to investigate the relationship among social support, health behavior self-efficacy, anxiety, and the physical activity (PA) levels of lung cancer survivors, and to analyze whether health behavior self-efficacy and anxiety mediate the relationship between social support and PA levels.

METHODS

In a cross-sectional study of 1128 lung cancer survivors from 16 Chinese hospitals, we collected demographic data and administered the Social Support Rating Scale (SSRS), Self-Rated Abilities for Health Practices Scale (SRAHP), Anxiety Scale (AS), and International Physical Activity Questionnaire (IPAQ). SPSS 25.0 was used for descriptive analyses, while the structural equation model in SPSS AMOS 24.0 was used to identify the direct, indirect, and total effects among variables.

RESULTS

There were significant correlations among SSRS, SRAHP, AS, and PA (P < 0.01). Model outcomes revealed a positive association between social support and health behavior self-efficacy (β = 0.732, P < 0.001). Health behavior self-efficacy positively correlated with PA levels (β = 0.228, P < 0.001) and negatively with anxiety (β=-0.252, P = 0.001). Moreover, health behavior self-efficacy was found to partially mediate the relationship between social support and PA (β = 0.174, P < 0.001).

CONCLUSIONS AND IMPLICATIONS FOR CANCER SURVIVORS

This study revealed a positive correlation between social support and health behavior self-efficacy, and between health behavior self-efficacy and PA levels among lung cancer survivors. Additionally, health behavior self-efficacy mediated the relationship between social support and PA levels. In future clinical practice, medical and nursing staff should assess social support and health behavior self-efficacy in lung cancer survivors to inform personalized PA interventions.

The effectiveness of E-health interventions promoting physical activity in cancer survivors: a systematic review and meta-analysis of randomized controlled trials

PURPOSE

This systematic review and meta-analysis aimed to identify whether E-health interventions effectively improve physical activity (PA) in cancer survivors.

METHODS

PubMed, Web of Science, and Cochrane Library databases were searched from inception to October 21, 2023. Randomized controlled trials reporting the effect of E-health interventions on PA among cancer survivors were included. Random-effect models were used to calculate standardized mean differences (SMD) and the 95% confidence interval (CI).

RESULTS

In total, 15 trials with 2,291 cancer survivors were included in this meta-analysis. The results showed that E-health interventions improved moderate to vigorous physical activity (MVPA) among cancer survivors (SMD = 0.26, 95% CI 0.08, 0.43, N = 8, p < 0.001, I2 = 37%), as well as moderate physical activity (MPA) (SMD = 0.22, 95% CI 0.05, 0.38, N = 9, p < 0.001, I2 = 28%) and vigorous physical activity (VPA) (SMD = 0.34, 95% CI 0.15, 0.54, N = 6, p < 0.001, I2 = 11%).

CONCLUSION

E-health interventions are effective at promoting PA among cancer survivors. As current research primarily focuses on immediate post-intervention measurements with limited follow-up data, further investigation is required to explore the long-term effects of E-health interventions on PA.

The effect of mind-body exercise in lung cancer patients: a meta-analysis of RCTs

PURPOSE

This study aimed to evaluate the impact of mind-body exercise (yoga, tai chi, qigong, etc.) on lung cancer.

METHODS

We performed a literature search of the electronic databases PubMed, Web of Science, Cochrane Library, Embase, CNKI, CBM, WanFang Data, and VIP from their inception to 16 May 2023. The primary outcome was the 6-min walk test (6MWT), while the secondary outcomes were anxiety levels and quality of life (QoL). Two independent reviewers performed the data extraction using a predefined protocol and assessed the risk of bias using the Cochrane risk of bias (ROB) tool for randomized controlled trials, with differences agreed by consensus. Meta-analysis was performed using RevMan 5.4 and Stata 15 software to analyze the extracted data.

RESULTS

This meta-analysis included a total of 11 studies involving 897 patients. The results indicated that compared to the usual care group, lung cancer patients in the mind-body exercise group could increase the 6-min walk distance (5 studies, 346 participants, WMD: 18.83, 95% CI (7.55, 30.10) P = 0.001), reduce anxiety levels (4 studies, 362 participants, SMD: - 1.51, 95% CI (- 1.74, - 1.27), P < 0.05), and enhance the overall quality of life (6 studies, 594 participants, SMD: 0.71, 95% CI (0.10, 1.31), P = 0.02). The overall certainty of the evidence for all outcomes was low; seven studies were judged to be at low risk of bias, and four studies were judged to be at moderate risk of bias.

CONCLUSION

Mind-body exercise could improve exercise capacity in lung cancer survivors, reduce anxiety, and positively affect overall quality of life.

Telemedicine-based inspiratory muscle training and walking promotion with lung cancer survivors following curative intent therapy: a parallel-group pilot randomized trial

PURPOSE

Following curative-intent therapy of lung cancer, many survivors experience dyspnea and physical inactivity. We investigated the feasibility, acceptability, safety, and potential efficacy of inspiratory muscle training (IMT) and walking promotion to disrupt a postulated "dyspnea-inactivity" spiral.

METHODS

Between January and December 2022, we recruited lung cancer survivors from Kaiser Permanente Colorado who completed curative-intent therapy within 1-6 months into a phase-IIb, parallel-group, pilot randomized trial (1:1 allocation). The 12-week intervention, delivered via telemedicine, consisted of exercise training (IMT + walking), education, and behavior change support. Control participants received educational materials on general exercise. We determined feasibility a priori: enrollment of ≥ 20% eligible patients, ≥ 75% retention, study measure completion, and adherence. We assessed acceptability using the Telemedicine-Satisfaction-and-Usefulness-Questionnaire and safety events that included emergency department visits or hospitalizations. Patient-centered outcome measures (PCOMs) included dyspnea (University-of-California-San-Diego-Shortness-of-Breath-Questionnaire), physical activity (activPAL™ steps/day), functional exercise capacity (mobile-based-six-minute-walk-test), and health-related quality of life (HRQL, St.-George's-Respiratory-Questionnaire). We used linear mixed-effects models to assess potential efficacy.

RESULTS

We screened 751 patients, identified 124 eligible, and consented 31 (25%) participants. Among 28 participants randomized (14/group), 22 (11/group) completed the study (79% retention). Intervention participants returned > 90% of self-reported activity logs, completed > 90% of PCOMs, and attended > 90% of tele-visits; 75% of participants performed IMT at the recommended dose. Participants had high satisfaction with tele-visits and found the intervention useful. There was no statistically significant difference in safety events between groups. Compared to control participants from baseline to follow-up, intervention participants had statistically significant and clinically meaningful improved HRQL (SGRQ total, symptom, and impact scores) (standardized effect size: -1.03 to -1.30).

CONCLUSIONS

Among lung cancer survivors following curative-intent therapy, telemedicine-based IMT + walking was feasible, acceptable, safe, and had potential to disrupt the "dyspnea-inactivity" spiral. Future efficacy/effectiveness trials are warranted and should incorporate IMT and walking promotion to improve HRQL.

Physical activity, obesity, and quality of life among rural Australian cancer survivors: a cross-sectional study

PURPOSE

We aimed to describe physical activity (PA), obesity, and quality of life (QoL) among rural Australian cancer survivors, assess whether total and item-specific QoL are associated with sufficient PA and obesity, and assess whether PA and obesity interact with respect to QoL.

METHODS

In a cross-sectional study, convenience sampling was used to recruit adult cancer survivors via a chemotherapy day unit and allied health professionals at a rural hospital in Baw Baw Shire, Australia. Exclusion criteria were acute malnutrition and end-of-life care. PA and QoL were measured using Godin-Shephard and 7-item Functional Assessment of Cancer Therapy (FACT-G7) questionnaires, respectively. Factors associated with total and item-specific QoL were assessed via linear and logistic regression, respectively.

RESULTS

Among 103 rural cancer survivors, the median age was 66 years, 35% were sufficiently physically active, and 41% presented with obesity. Mean/median total QoL scores were 17 on the FACT-G7 scale (0-28; higher scores indicate better QoL). Sufficient PA was associated with better QoL ([Formula: see text]=2.29; 95% confidence interval [CI] = 0.26, 4.33) and more energy (odds ratio [OR] = 4.00, 95% CI = 1.48, 10.78) while obesity was associated with worse QoL ([Formula: see text]=-2.09; 95% CI = -4.17, -0.01) and more pain (OR = 3.88, 95% CI = 1.29, 11.68). The PA-obesity interaction was non-significant (p-value = 0.83).

CONCLUSIONS

This is the first known study conducted among rural survivors of any cancer to find sufficient PA and obesity are associated with better and worse QoL, respectively. PA, weight management, and QoL-including energy and pain-should be considered when targeting and tailoring supportive care interventions for rural cancer survivors.

Might Dog Walking Reduce the Impact of COPD on Patients' Life?

Low levels of physical activity (PA) lead to a worsening of physical condition and contributes to multimorbidity in Chronic Obstructive Respiratory Disease (COPD). Unsupervised PA related to dog ownership may contribute to reducing sedentary behavior. We aimed to investigate the relationship between dog walking, patient-reported outcomes (PROs) and exacerbations in COPD. A pre-defined sample of 200 COPD patients (dog owners and non-dog owners) with symptomatic COPD was sourced from a database representative of the Italian population. A computer-assisted personal interview was used to assess health status impairment (CAT), fatigue (FACIT), health-related quality of life (HRQoL) (EQ-5D), and PA frequency. In the whole sample, PA was associated with better CAT, EQ-5D, VAS, FACIT scores and reduced number of exacerbation (p < 0.001). Under the same CAT scores, dog-walking duration was associated with a better HRQoL (EQ5D, p = 0.015) and less fatigue (FACIT, p = 0.017). In an adjusted regression model, walking dogs >30 min was associated with lower fatigue (FACIT) than having no dogs and walking dogs <15 min (p = 0.026 and p = 0.009, respectively). Motivation related to dog walking could modify patients’ tendency to focus on symptoms during PA and, therefore, to perceive the fatigue. Dog walking may be effective for increasing and maintaining regular PA, reducing the subjective impact of COPD.

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.
