Abstract 4136755: Associations of Pulmonary Hypertension and Lung Cancer: A Prospective Cohort Study of Half a Million UK Biobank Participants

Background: Pulmonary hypertension (PH) and lung cancer (LC) are both significant public health issues with substantial morbidity and mortality. Recent studies suggest potential associations between pulmonary vascular diseases and LC due to shared risk factors and pathophysiological mechanisms, yet comprehensive research in large populations is scarce. Methods: This prospective cohort study utilized data from the UK Biobank, with baseline assessment between 2006 and 2010 and follow-up until November 30, 2023, for England and Scotland, and May 31, 2022, for Wales. We included 6,425 participants with LC, identified using linked cancer registry data, and followed them for the incidence of PH over a period of 10 years. We adjusted for potential confounders including age, ethnics, sex, smoking status, BMI, and histologic subtypes of LC. Statistical analyses were performed using Time-dependent Cox proportional hazards models to estimate the associations between PH and LC. Results: Of 502,173 participants in this prospective cohort, 6,425 were diagnosed with LC, while 494,451 did not receive the LC diagnosis. The prevalence of PH in the LC cohort and the no-LC cohort were 0.64% (1,494 of 3,142 women [47.55%]) and 2.40% (59 of 154 women [38.31%]), respectively, with significant difference between the two groups (p<0.001). In the LC cohort, the mortality rates of patients without PH and with PH were 69.18% and 77.92% (p=0.020). Among the patients diagnosed with LC and PH, 33.12% were diagnosed with LC after PH (PH-LC), while 66.88% were diagnosed with LC before PH (LC-PH). And the mortality rates of the PH-LC group and the LC-PH group were 78.43% and 77.67%, respectively, with no significant difference between the two groups (p=0.915). Time-dependent Cox regression analysis showed that PH shows an increasing trend in risk (5th year HR: 3.22, 95% CI: 2.09-4.99, p-value < 0.001), highlighting its significant impact on LC long-term prognosis. Conclusion: To conclude, the presence of PH significantly increased the risk of mortality in participants with LC, especially for the long-term LC survivors. And certain percentage of patients were diagnosed with LC before PH, but they had no significant difference between the patients with LC after PH.

Gut microbiome metabolites, molecular mimicry, and species-level variation drive long-term efficacy and adverse event outcomes in lung cancer survivors

The influence of the gut microbiota on long-term immune checkpoint inhibitor (ICI) efficacy and immune-related adverse events (irAEs) is poorly understood, as are the underlying mechanisms. We performed gut metagenome and metabolome sequencing of gut microbiotas from patients with lung cancer initially treated with anti-PD-1/PD-L1 therapy and explored the underlying mechanisms mediating long-term (median follow-up 1167 days) ICI responses and immune-related adverse events (irAEs). Results were validated in external, publicly-available datasets (Routy, Lee, and McCulloch cohorts). The ICI benefit group was enriched for propionate (P=0.01) and butyrate/isobutyrate (P=0.12) compared with the resistance group, which was validated in the McCulloch cohort (propionate P<0.001, butyrate/isobutyrate P=0.002). The acetyl-CoA pathway (P=0.02) in beneficial species mainly mediated butyrate production. Microbiota sequences from irAE patients aligned with antigenic epitopes found in autoimmune diseases. Microbiotas of responsive patients contained more lung cancer-related antigens (P=0.07), which was validated in the Routy cohort (P=0.02). Escherichia coli and SGB15342 of Faecalibacterium prausnitzii showed strain-level variations corresponding to clinical phenotypes. Metabolome validation reviewed more abundant acetic acid (P=0.03), propionic acid (P=0.09), and butyric acid (P=0.02) in the benefit group than the resistance group, and patients with higher acetic, propionic, and butyric acid levels had a longer progression-free survival and lower risk of tumor progression after adjusting for histopathological subtype and stage (P<0.05). Long-term ICI survivors have coevolved a compact microbial community with high butyrate production, and molecular mimicry of autoimmune and tumor antigens by microbiota contribute to outcomes. These results not only characterize the gut microbiotas of patients who benefit long term from ICIs but pave the way for "smart" fecal microbiota transplantation.

Cardiovascular disease burden and risk factor management in cancer survivors: insights from a large-scale East London cohort

Abstract Introduction Improvements in cancer survival have led to an urgent need to address long-term health issues among survivors, notably increased risk of cardiovascular disease (CVD). Shared risk factors may underpin at least part of this excess risk. Aims To investigate differences in cardiovascular risk profile between cancer survivors and controls; and to assesses the management of hypertension and statin use among cancer survivors compared with controls in a multi-ethnic and socio-economically diverse population. Methods The data were obtained from electronic health records of 1.2 million people registered with general practices in East London. It provides a snapshot of health records at the time of data extraction (01/01/2023). We identify individuals with record of past cancer (grouped into 20 cancer types) and their cardiovascular profile. Each cancer-exposed patient was age- and sex-matched to four non-cancer comparators. Multivariable logistic regression, with extensive adjustment for demographic and health-related variables, was used to elucidate the independent associations of past cancer with a range of cardiovascular outcomes. Patterns of guideline-directed risk factor control among cancer patients with hypertension and ischaemic CVDs (vs non-cancer controls) were assessed. Results The study consisted of 18,839 cancer survivors and 75,356 matched controls (64±15 years, 43% male), with marked ethnic diversity (cancer survivors: 48% White, 24% Black and 22% Asian) and socio-economic deprivation. Compared to matched controls, patients with past cancer had a higher prevalence of hypertension (44% vs. 41%) and chronic kidney disease (18% vs. 14%). We observed a higher prevalence of CVDs including venous thromboembolism (VTE) (5.6% vs. 2.8%), atrial fibrillation (AF) (6.5% vs. 5%), and heart failure (HF) (4.4% vs. 3.4%) among cancer survivors. Regression models fully adjusted for shared risk factors demonstrated an increased risk of a range of CVDs in patients with (any) past cancer, including VTE (OR 2.01), HF (OR 1.31) and AF (OR 1.27). CVD risk varied across cancer types (Figure 1). For example, lung cancer survivors had an elevated risk of VTE (OR 4.02), AF (OR 2.47), IHD (OR 1.45) and peripheral artery disease (OR 1.67) while colorectal cancer survivors had increased risks of VTE (OR 2.68), HF (OR 1.4) and AF (OR 1.32). In subgroup analyses, control of blood pressure and cholesterol did not differ significantly across cancer survivors and matched controls with hypertension and ischaemic CVDs, respectively. Conclusion We show higher burden of VRFs and an increased risk of CVDs among cancer survivors compared with non-cancer controls, with notable variation across cancer types. The lack of difference in control of blood pressure and cholesterol between cancer survivors and controls suggests that these risk factors did not explain the increased risk. Suggesting that an individualised approach to risk management is likely to be warranted.Risk of CVDs in Cancer Survivors

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.

Qualitative acceptability testing of a paper-based care planner in patients with metastatic non-small cell lung cancer (mNSCLC).

259 Background: Patients with cancer and their caregivers often describe the fragmented, multi-modal and multi-provider cancer care experience as undertaking a difficult expedition without a map. Based on her experience in 2020 and using self and family management theories (doi: 10.1016/j.outlook.2008.10.004.), Daswani developed a pan-cancer patient planner, which helps patients and families prepare for appointments, track symptoms, and manage their care. It has been available since 2021 through hospitals, advocacy organizations and online retail channels. We adapted and customized the pan-cancer planner for patients with mNSCLC. We tested acceptability through a series of structured patient interviews, and a brief, in-person survey tool. Methods: A lung cancer survivor recruited members of the lung cancer community to participate in a 30-minute structured virtual interview. After reviewing the planner, interviewees were asked: 1) about their diagnosis and treatment experience and 2) to provide semi-structured feedback. We conducted interviews until thematic saturation was reached. We modified the planner based on interview results, distributed planners to patients and care-partners at a major lung cancer patient summit and immediately collected a brief survey to assess patient knowledge of their diagnosis and motivation for planner access. Results: The table shows high level thematic groups of interview responses. Interviewed patients concluded that the planner would have improved their experience because they would have: Stayed organized, facilitated note-taking during appointments, better tracked and managed symptoms &amp; meds, been more confident in decision-making and been able to journal, stay grounded and more mindful. Of 94 planners distributed at the summit, 49 patients knew their diagnosis, 31 knew their stage, 28 knew their cancer mutation status. Of the four domains of self-management, positive responses were: 1. Increase confidence 44 (47%) 2. Gain peace of mind 40 (43%) 3. Stay organized 58 (62%) 4. Manage meds &amp; symptoms 42 (45%). Conclusions: A paper based mNSCLC specific planner is acceptable to patients and they anticipate it would help with all four domains of self management (confidence, peace of mind, organization, med and symptom management) and enhance a difficult experience. We plan further usability testing as we did with the breast cancer planner (JCO Oncol Pract 19, 2023 (suppl 11; abstr 552)). Interviews of 8 (7 female, 1 male) patients (3 with English as a second language) were held in December 2023.

Risk factors for cancer-related cognitive impairment among individuals with lung cancer: a systematic review and meta-analysis.

Cancer-related cognitive impairment (CRCI) exerts a negative impact on the quality of life in lung cancer survivors. Risk factors for CRCI in lung cancer patients remain unclear.This study aimed to identify risk factors for CRCI in lung cancer patients. A comprehensive literature search was conducted across PubMed, CINAHL, Web of Science, Wanfang, VIP Database, Embase, and China National Knowledge Infrastructure (CNKI) from their inception until March 10, 2024. Studies were screened, data extracted, and quality assessed using the Agency for Healthcare Research and Quality and Newcastle-Ottawa Scale. Meta-analysis was performed using RevMan 5.4, assessing risk factors through odds ratios (OR) with 95% confidence intervals (CIs). The analysis was comprised of nine studies, including 1,305 patients. Seven studies were high quality, and two were moderate quality. Identified risk factors for CRCI in lung cancer patients included advanced age (OR = 3.51, 95%CI: 2.14-5.74, I2 = 0.0%), cranial irradiation (OR = 2.12, 95% CI: 1.39-3.22, I2 = 0.0%), anxiety (OR = 2.92, 95% CI: 1.65-5.25, I2 = 37%), and symptom cluster burden (OR = 4.85, 95% CI: 2.99-7.87, I2 = 0.0%). Physical activity (OR = 0.37, 95% CI; 0.23-0.58, I2 = 9.0%) was identified as a protective factor. Advanced age, cranial irradiation, anxiety, and symptom cluster burden are significant risk factors for CRCI, while physical activity serves as a protective factor. These insights provide healthcare professionals with an evidence-based framework for managing CRCI in lung cancer patients.

The links between symptom burden, illness perception, psychological resilience, social support, coping modes, and cancer-related worry in Chinese early-stage lung cancer patients after surgery: a cross-sectional study

ObjectivesThis study aims to investigate the links between the clinical, demographic, and psychosocial factors and cancer-related worry in patients with early-stage lung cancer after surgery.MethodsThe study utilized a descriptive cross-sectional design. Questionnaires, including assessments of cancer-related worry, symptom burden, illness perception, psychological resilience, coping modes, social support and participant characteristics, were distributed to 302 individuals in early-stage lung cancer patients after surgery. The data collection period spanned from January and October 2023. Analytical procedures encompassed descriptive statistics, independent Wilcoxon Rank Sum test, Kruskal-Wallis- H- test, Spearman correlation analysis, and hierarchical multiple regression.ResultsAfter surgery, 89.07% had cancer-related worries, with a median (interquartile range, IQR) CRW score of 380.00 (130.00, 720.00). The most frequently cited concern was the cancer itself (80.46%), while sexual issues were the least worrisome (44.37%). Regression analyses controlling for demographic variables showed that higher levels of cancer-related worry (CRW) were associated with increased symptom burden, illness perceptions, and acceptance-rejection coping modes, whereas they had lower levels of psychological resilience, social support and confrontation coping modes, and were more willing to obtain information about the disease from the Internet or applications. Among these factors, the greatest explanatory power in the regression was observed for symptom burden, illness perceptions, social support, and sources of illness information (from the Internet or applications), which collectively explained 52.00% of the variance.ConclusionsHealthcare providers should be aware that worry is a common issue for early stage lung cancer survivors with a favorable prognosis. During post-operative recovery, physicians should identify patient concerns and address unmet needs to improve patients’ emotional state and quality of life through psychological support and disease education.

Racial and ethnic differences in second primary lung cancer risk among lung cancer survivors.

Recent therapeutic advances have improved survival among lung cancer (LC) patients, who are now at high risk of second primary lung cancer (SPLC). Hispanics comprise the largest minority in the United States, who have shown a lower LC incidence and mortality than other races, and yet their SPLC risk is poorly understood. We quantified the SPLC incidence patterns among Hispanics vs other races. We used data from the Multiethnic Cohort, a population-based cohort of 5 races (African American, Japanese American, Hispanic, Native Hawaiian, and White), recruited between 1993 and 1996 and followed through 2017. We identified patients diagnosed with initial primary lung cancer (IPLC) and SPLC via linkage to Surveillance, Epidemiology, and End Resultsregistries. We estimated the 10-year cumulative incidence of IPLC (in the entire cohort) and SPLC (among IPLC patients). A standardized incidence ratio (SIR) was calculated as the ratio of SPLC-to-IPLC incidence by race and ethnicity. Among 202 692 participants, 6788 (3.3%) developed IPLC over 3 871 417 person-years. The 10-year cumulative IPLC incidence was lower among Hispanics (0.80%, 0.72 to 0.88) vs Whites (1.67%, 1.56 to 1.78) or Blacks (2.44%, 2.28 to 2.60). However, the 10-year SPLC incidence following IPLC was higher among Hispanics (3.11%, 1.62 to 4.61) vs Whites (2.80%, 1.94 to 3.66) or Blacks (2.29%, 1.48 to 3.10), resulting in a significantly higher SIR for Hispanics (SIR = 8.27, 5.05 to 12.78) vs Whites (SIR = 5.60, 4.11 to 7.45) or Blacks (SIR = 3.48, 2.42 to 4.84; P < .001). Hispanics have a higher SPLC incidence following IPLC than other races, which may be potentially due to better survival after IPLC and extended duration for SPLC development. Continuing surveillance is warranted to reduce racial disparities among LC survivors.

Missed Follow-up is associated with worse survival in stage I lung cancer: results from a large multi-site academic hospital system

The purpose of this study is to examine the effect of early incomplete follow-up on overall survival among stage I lung cancer patients. Patients with clinical stage I lung cancer at our institution between 2007 and 2016 were identified (N = 1111). Exclusions included < 18 years of age (N = 2), missing stage or demographics (N = 56), incomplete appointment data or had only one scheduled appointment (N = 351), or did not survive for at least 1 year after diagnosis (N = 120). Missed appointments were defined as unattended follow-up appointments within the first year of diagnosis without an attended appointment in the subsequent 60 days. The primary outcome was the hazard ratio (HR) for death associated per 10% increase in missed oncology follow-up appointments. Univariable and descriptive statistics were performed, and a multivariable landmark Cox regression model was created to examine the effect of missed oncology follow-up on survival. A total of 582 patients were analyzed with median follow-up of 3.2 years and median age of 69 years. On multivariable analysis controlling for age, sex, race, insurance status, and definitive treatment type the HR for death was 1.44 (95% CI 1.05–1.97) for every 10% increase in missed appointments. Incomplete oncologic follow-up may negatively impact overall survival among survivors of early-stage lung cancer.

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

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

Radiotherapy-Related Clinical and Functional Sequelae in Lung Cancer Survivors

EGFR-TKIs - induced cardiotoxicity in NSCLC: incidence, evaluation, and monitoring.

The advent of targeted drug therapy has greatly changed the treatment landscape of advanced non-small cell lung cancer(NSCLC), but the cardioxic side effects of targeted drug anti-cancer therapy seriously affect the prognosis of NSCLC, and it has become the second leading cause of death in cancer patients. Therefore, early identification of the cardiotoxic side effects of targeted drugs is crucial for the prevention and treatment of cardiovascular diseases. The cardiotoxic side effects that may be caused by novel targeted drugs epidermal growth factor receptor inhibitors, including thromboembolic events, heart failure, cardiomyopathy, arrhythmia and hypertension, are discussed, and the mechanisms of their respective adverse cardiovascular reactions are summarized, to provide useful recommendations for cardiac management of patients with advanced lung cancer to maximize treatment outcomes for lung cancer survivors. Clinicians need to balance the risk-benefit ratio between targeted therapy for malignant tumors and drug-induced cardiotoxicity, and evaluate and monitor TKIs-induced cardiotoxicity through electrocardiogram, cardiac imaging, biomarkers, etc., so as to remove the susceptibility risk factors as soon as possible and provide a reference for the clinical use of such drugs in the treatment of malignant tumors.

Musculoskeletal Disorders Related to Upper Limb Disability after One-Year Lung Cancer Resection.

Lung resection represents the main curative treatment in lung cancer; however, this surgical process leads to several disorders in tissues and organs. Previous studies have reported cardiovascular, pulmonary, and muscular disturbances that affect the functional capacity of these patients in the short, mid, and long term. However, upper limb impairment has been scarcely explored in the long term, despite the relevance in the independence of the patients. The aim of this study was to characterize the upper limb impairment in survivors of lung cancer one year after pulmonary resection. In this observational trial, patients who underwent lung cancer surgery were compared to control, healthy subjects matched by age and gender. Upper limb musculoskeletal disorders (shoulder range of motion, pain pressure threshold, nerve-related symptoms) and functional capacity (upper limb exercise capacity) were evaluated one-year post-surgery. A total of 76 survivors of lung cancer and 74 healthy subjects were included in the study. Significant differences between groups were found for active shoulder mobility (p < 0.05), widespread hypersensitivity to mechanical pain (p < 0.001), mechanosensitivity of the neural tissue (p < 0.001), and upper limb exercise capacity (p < 0.001). Patients who undergo lung cancer surgery show upper limb musculoskeletal disorders and upper limb functional impairment after a one-year lung resection. This clinical condition could limit the functionality and quality of life of patients with lung cancer.
