Introduction: In France, 40% of patients diagnosed with lung cancer are ≥70 years old, but these are under-represented in clinical trials. Using data from the French Epidemiological Strategy and Medical Economics (ESME) platform on Lung Cancer (LC), the objective is to provide an overview of the management and the prognosis of older patients with advanced or metastatic non-small cell lung cancer (AM-NSCLC) in a real-world context., Materials and Methods: From the ESME-LC database, we selected patients with AM-NSCLC (stage IIIB, IIIC, and IV), diagnosed between 2015 and 2019, and who received first-line systemic treatment. Demographics, tumour characteristics, and treatment received were described in patients ≥70, and compared to younger ones. Real-world progression-free survival (rwPFS) and overall survival (OS) were evaluated using the multivariable Cox model., Results: Among 10,002 patients with AM-NSCLC, the median age was 64 years, with 2,754 (27.5%) aged ≥70. In comparison with patients <70, older patients were more often male, with worse performance status and more comorbidities, but they were less underweight and more often non-smokers. The proportion of EGFR mutated non-squamous NSCLC was higher in older patients (25.0% vs 12.8%, p < 0.001), particularly among smokers and former smokers (12.7% vs 7.3%, p < 0.001). Among patients ≥70, 76.6% received first-line chemotherapy (including 67.0% treated with a platinum-based doublet), 15.0% received only targeted therapy, and 11.0% received immunotherapy (alone or in combination). Median first-line rwPFS was 5.1 months (95% confidence interval [CI] = [4.8;5.4]) for patients ≥70 and 4.6 months (95%CI = [4.4;4.8]) for patients <70, but age was not associated with rwPFS in multivariable analysis. Median OS was 14.8 months (95%CI = [13.9;16.1]) for patients ≥70 and 16.7 months (95%CI = [15.9;17.5]) for patients <70, with a significant effect of age in multivariable analysis for patients treated with chemotherapy and/or with targeted therapy, but not for patients treated with immunotherapy (alone or in combination with chemotherapy)., Discussion: In this real-world cohort of patients with AM-NSCLC, age was not associated with first-line rwPFS regardless of treatment received, nor with OS for patients receiving immunotherapy. However, OS was significantly shorter for patients aged ≥70 treated with chemotherapy or with targeted therapy alone., Competing Interests: Declaration of Competing Interest Mathilde Cabart reports non-financial support from Janssen, non-financial support from Pfizer, outside the submitted work.

Background: Management of stage-III-N2 non-small-cell lung cancer (NSCLC) based on a multimodal strategy (surgery or radiotherapycombined with systemic drugs) remains controversial. Patients are treated with a curative intent, and available data suggestprolonged survival after complete resection. However, no consensual definition of "tumor resectability" exists. This study aimed to analyze the concordanceamong French tumor board meeting (TBM)-emittedtherapeutic decisions forstage-III-N2 NSCLC., Methods: Six patients with stage-III-N2 NSCLC discussed at Saint-Etienne University Hospital'sthoracic TBMs were selected, anonymouslyreported, and submitted to the participating TBMs. The primary goal of this multicenter, prospective, observational study was to assess the consistency of TBMpanel decisions for each case. The secondary endpointwas identifying the demographic or technical factors that potentiallyaffected decision-making., Results: Twenty-seven TBMs from university hospitals, a cancer center, general hospitals, and a private hospitalparticipated in this study. None of their decisions for the six cases were unanimous.The decisions were homogenous for three cases (78%, 85%, and 88% TBMs opted for medical treatment, respectively),andmore ambivalent for the other three (medical versus surgical strategies were favored by 44%/56%, 46%/54%, and 58%/42% TBMs, respectively). Interestingly, decisions regarding chemoradiationand perioperative chemotherapyinthe medical and surgical strategies, respectively, were also discordant. Hospital type, specialist participation in TBMs, and activity volumes were not significantly associated with therapeutic decisions., Conclusion: The results of this study highlight substantial disparities amongFrench TBMs regarding therapeutic management of stage-III-N2 NSCLC. The decisions were not associated with local conditions., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 The Author(s).

Introduction: Predictors for mortality and toxicity in older patients with cancer are mainly studied in cohorts with various cancers at different stages. This study aims to identify predictive geriatric factors (PGFs) for early death and severe chemotherapy related adverse events (CRAEs) in patients aged ≥70 years with metastatic non-small-cell lung cancer (mNSCLC)., Material and Methods: This is a secondary analysis of the multicenter, randomized, phase 3 ESOGIA trial that compared, for patients ≥70 years with mNSCLC, a treatment algorithm based on performance status and age to another algorithm based on geriatric assessment. To identify PGFs of three-month mortality and grade 3, 4, or 5 CRAEs, multivariate Cox models and logistic models, adjusted for treatment group and center, and stratified by randomization arm, were constructed., Results: Among 494 included patients, 145 (29.4%) had died at three months and 344 (69.6%) had severe chemotherapy toxicity. For three-month mortality, multivariate analyses retained mobility (Test Get up and Go), instrumental activity of daily living (IADL) dependence and weight loss as PGFs. The combined effect of IADL ≤2/4 and weight loss ≥3 kg was strongly associated with three-month mortality (adjusted hazard ratio: 5.71 [95% confidence interval [CI]: 2.64-12.32]). For chemotherapy toxicity, Charlson Comorbidity Index ≥2 was independently associated with grade3, 4, or 5 CRAEs (adjusted odds ratio [95% CI]: 1.94 [1.06-3.56])., Discussion: Mobility, IADL dependence, and weight loss were predictive of three-month mortality in a population aged ≥70 years treated for mNSCLC, while comorbidities were independently associated with severe chemotherapy toxicity., Competing Interests: Declaration of Competing Interest All authors have no conflicts of interest and disclosures., (Copyright © 2023.

Background: In an open-label multicenter non-randomized non-comparative phase II study in patients with stage IIIB/IV non-squamous non-small cell lung cancer (NSCLC), oncogenic addiction (EGFR mutation or ALK/ROS1 fusion), with disease progression after tyrosine-kinase inhibitor and no prior chemotherapy (NCT04042558), atezolizumab, carboplatin, pemetrexed with or without bevacizumab showed some promising result. Beyond the clinical evaluation, we assessed safety and patient-reported outcomes (PROs) to provide additional information on the relative impact of adding atezolizumab to chemotherapy with and without bevacizumab in this population., Materials: Patients received platinum-pemetrexed-atezolizumab-bevacizumab (PPAB cohort) or, if not eligible, platinum-pemetrexed-atezolizumab (PPA cohort). The incidence, nature, and severity of adverse events (AEs) were assessed. PROs were evaluated using the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ-Core 30 and EORTC QLQ-Lung Cancer 13)., Result: Overall, 68 (PPAB) and 72 (PPA) patients were evaluable for safety. Grade 3-4 AEs occurred in 83.8% (PPAB) and 63.9% (PPA). Grade 3-4 atezolizumab-related AEs occurred in 29.4% and 19.4%, respectively. Grade 3-4 bevacizumab-related AEs occurred in 36.8% (PPAB). Most frequent grade 3-4 AEs were neutropenia (19.1% in PPAB; 23.6% in PPA) and asthenia (16.2% in PPAB; 9.7% in PPA). In PPAB, we observed a global stability in global health security (GHS) score, fatigue and dyspnea with a constant tendency of improvement, and a significant improvement in cough. In PPA, we observed a significant improvement in GHS score with a significant improvement in fatigue, dyspnea and cough. At week 54, we observed an improvement from baseline in GHS score for 49.2% of patients. In both cohorts, patients reported on average no clinically significant worsening in their overall health or physical functioning scores., Conclusion: PPAB and PPA combinations seem tolerable and manageable in patients with stage IIIB/IV non-squamous NSCLC with oncogenic addiction (EGFR mutation or ALK/ROS1 fusion) after targeted therapies., Competing Interests: Declaration of competing interest The authors declare the following financial interests/personal relationships which may be considered as potential competing interests: P.T report adviser and consultant for TAKEDA, BMS, ROCHE, JANSSENS, AMGEN and ASTRA ZENECA; support for attending meeting for TAKEDA, BMS, ASTRA ZENECA and JANSSENS.

Obstructive sleep apnea syndrome (OSA) has been associated with increased cancer incidence and aggressiveness. One hypothesis to support this association is the implication of immune response, particularly the programmed cell death pathway, formed by the receptor PD-1 and its ligand PD-L1. Recent studies have shown dysregulation of this pathway in severe OSA patients. It has also been shown that small extracellular vesicles (sEVs) carrying PD-L1 induce lymphocyte dysfunction. Thus, the aim of our study was to analyze the expression of PD-L1 on sEVs of OSA patients and to evaluate the role of sEVs on lymphocyte activation and cytotoxicity. Circulating sEVs were isolated from OSA patients and the control group. Lymphocytes were isolated from the control group. Circulating sEVs were characterized by western blot, nanotracking analysis, and flow cytometry and were incubated with lymphocytes. Our results show no differences in the quantity and composition of sEVs in OSA patients and no significant effects of sEVs in OSA patients on lymphocyte activation and cytotoxicity. These results suggest that OSA does not modify PD-L1 expression on sEVs, which does not contribute to dysregulation of cytotoxic lymphocytes.

Background: Few data are available on the impact of venous thrombotic events (VTE) in patients with metastatic non-small cell lung cancer (mNSCLC) treated with immunotherapy., Methods: This is a secondary analysis of the ESKEYP study, a national, retrospective, multicenter study that consecutively included all PD-L1 ≥ 50% mNSCLC patients who initiated first-line treatment with pembrolizumab monotherapy. From May 2017 to November 2019, 845 patients were included (from availability of pembrolizumab in this indication in France to the authorization of the combination with chemotherapy). Impact of VTE and patient characteristics were analyzed., Results: Of the 748 patients (88.5%) with available data, the incidence of VTE was 14.8% (111/748). At pembrolizumab initiation, Khorana score was ≥ 2 for 55.0% (61/111) of them. Recurrence of VTE was reported for 4 of the 111 patients and 5 had bleeding complications. Patients with VTE were significantly younger, had more frequently long-term corticosteroids treatment and more often liver metastases. Progression-free survival (PFS) was significantly shorter in patients with VTE compared to patients without VTE: 6.1 (95% CI 4.1-9.0) months vs. 8.3 (6.9-10.3) months (p = 0.03). VTE did not significantly impact overall survival (OS): 15.2 (10.0-24.7) months with VTE and 22.6 (18.4-29.8) months without VTE (p = 0.07). In multivariate analysis for PFS and OS, HRs for VTE were 1.3 (0.99-1.71), p = 0.06 and 1.32 (0.99-1.76), p = 0.05., Conclusion: The incidence of VTE appears to be as high with in first-line immunotherapy as with chemotherapy in patients with mNSCLC, with in patient with VTE, a no significant trend for lower PFS and OS in multivariate analysis. more marked impact on PFS than on OS., (© 2023.

Outside clinical trials, few data are available on the effect of long-term first-line pembrolizumab in patients with advanced non-small-cell lung cancers with ≥50% of tumor cells expressing programmed cell death ligand 1 (PD-L1). This French, multicenter study included consecutive advanced patients with non-small-cell lung cancer given first-line pembrolizumab alone between May 2017 (authorization date for this indication) and November 2019 (authorization date for pembrolizumab-chemotherapy combination). Information was collected from patients' medical files, with a local evaluation of the response and progression-free survival (PFS). Overall survival (OS) was calculated from pembrolizumab onset using the Kaplan-Meier method. The analysis concerned 845 patients, managed in 33 centers: median age: 65 (range: 59-72) years, 67.8% men, 78.1% Eastern Cooperative Oncology Group performance status 0/1, 38.9%/51.5%/6.6% active, ex or never-smokers, respectively, 10.9%/16.8% taking or recently took corticosteroids/antibiotics, 69.6% nonsquamous histology, 48.9% ≥75% PD-L1-positive, and 20.8% had brain metastases at diagnosis. After a median (95% CI) follow-up of 45 (44.1-45.9) months, respective median (95% CI) PFS and OS lasted 8.2 (6.9-9.2) and 22 (8.5-25.9) months; 3-year PFS and OS rates were 25.4% and 39.4%, respectively. Multivariate analysis retained never-smoker status, adenocarcinoma histology, Eastern Cooperative Oncology Group performance status ≥2, and neutrophil/lymphocyte ratio >4 as being significantly associated with shorter survival, but not brain metastases at diagnosis or <75% PD-L1 tumor-cell expression. These long-term results of pembrolizumab efficacy based on a nationwide "real-world" cohort reproduced those obtained in clinical trials., (Copyright © 2023 Wolters Kluwer Health, Inc.

There is growing evidence suggesting that urban pollution has adverse effects on lung health. However, how urban pollution affects alveolar mesenchymal and epithelial stem cell niches remains unknown. This study aimed to determine how complex representative urban atmospheres alter alveolar stem cell niche properties. Mice were placed in an innovative chamber realistically simulating the atmosphere of a megalopolis, or "clean air," for 7 days. Lungs were collected, and fibroblasts and epithelial cells (EpCAM + ) were isolated. Proliferative capacities of fibroblasts were tested by population doubling levels (PDL), and microarray analyses were performed. Fibroblasts and EpCAM + cells from exposed, nonexposed, or naive mice were cocultured in organoid assays to assess the stem cell properties. Collagen deposition (Sirius red), lipofibroblasts (ADRP, COL1A1), myofibroblasts (αSMA), alveolar type 2 cells (AT2, SFTPC + ), and alveolar differentiation intermediate cell [ADI, keratin-8-positive (KRT8 + )/claudin-4-positive (CLDN4 + )] markers were quantified in the lungs. Fibroblasts obtained from mice exposed to urban atmosphere had lower PDL and survival and produced fewer and smaller organoids. Microarray analysis showed a decrease of adipogenesis and an increase of genes associated with fibrosis, suggesting a lipofibroblast to myofibroblast transition. Collagen deposition and myofibroblast number increased in the lungs of urban atmosphere-exposed mice. AT2 number was reduced and associated with an increase in ADI cells KRT8 + /CLDN4 + . Furthermore, EpCAM + cells from exposed mice also produced fewer and smaller organoids. In conclusion, urban atmosphere alters alveolar mesenchymal stem cell niche properties by inducing a lipofibroblast to myofibroblast shift. It also results in alveolar epithelial dysfunction and a fibrotic-like phenotype. NEW & NOTEWORTHY Urban pollution is known to have major adverse effects on lung health. To assess the effect of pollution on alveolar regeneration, we exposed adult mice to a simulated high-pollution urban atmosphere, using an innovative CESAM simulation chamber (Multiphase Atmospheric Experimental Simulation Chamber, https://cesam.cnrs.fr/). We demonstrated that urban atmosphere alters alveolar mesenchymal stem cell niche properties by inducing a lipofibroblast to myofibroblast shift and induces alveolar epithelial dysfunction.

Background: Few real-world data are available in patients with advanced metastatic non-small cell lung cancer (NSCLC) treated with first-line immunotherapy, particularly in those with brain metastases at treatment initiation., Methods: This was a national, retrospective, multicenter study that consecutively included all patients with PD-L1-positive (tumor proportion score ≥ 50%) advanced NSCLC who initiated first-line treatment with pembrolizumab as a single agent between May 2017 (date of availability of pembrolizumab in this indication in France) to November 22, 2019 (approval of the pembrolizumab-chemotherapy combination). Data were collected from medical records with local response assessment., Results: The cohort included 845 patients and 176 (20.8%) had brain metastases at diagnosis. There were no significant differences in outcomes for patients with and without brain metastases: 9.2 (95% CI 5.6-15) and 8 (95% CI 6.7-9.2, p = 0.3) months for median progression-free survival (PFS) and, 29.5 (95% CI 17.2-NA) and 22 (95% CI 17.8-27.1, p = 0.3) months for median overall survival (OS), respectively. Overall response rates were 47% and 45% in patients with and without cerebral metastases. In multivariate analysis, performance status 2-4 vs. 0-1 and neutrophil-to-lymphocyte ratio ≥ 4 vs. < 4 were the main independent negative factors for OS; brain metastasis was not an independent factor for OS., Conclusion: In this large multicenter cohort, nearly 20% of patients initiating pembrolizumab therapy for advanced NSCLC had cerebral metastases. There was no significant difference in response rates, PFS and OS between patients with and without brain metastases., (© 2022.

Objectives: Few data are available on the impact of KRAS mutation in patients with advanced non-squamous non-small cell lung cancer (aNSCLC) treated with immunotherapy. This analysis assessed the impact of KRAS mutation on the efficiency of first-line pembrolizumab immunotherapy in aNSCLC patients with PD-L1 ≥ 50 %., Methods: This was a secondary analysis of the ESCKEYP study, a retrospective, national, multicenter study which included consecutively all metastatic NSCLC patients who initiated first-line treatment with pembrolizumab monotherapy from May 2017 (date of pembrolizumab availability in this indication in France) to November 22, 2019 (pembrolizumab-chemotherapy combination approval). Progression-free survival (PFS) and overall survival (OS) were calculated from the start of pembrolizumab treatment by the Kaplan-Meier method. Tumor response and PFS were assessed locally., Results: Among the 681 non-squamous aNSCLC PD-L1 ≥ 50 % patients treated with pembrolizumab in the first line, 227 (33.0 %) had a KRAS mutation (KRAS G12C, 12.5 %; KRAS non-G12C, 20.5 %). Except among non-smokers (KRAS G12C, 0 %; KRAS non-G12C, 2.9 %; no KRAS mutation, 9.2 %), patients presented no differences in terms of sex, age, number and sites of metastatic disease at diagnosis, use of corticosteroids, use of antibiotics, and for biological factors between wild-type KRAS, KRAS G12C and non-KRAS G12C groups. Median (95 % CI) PFS in months were 7.0 (3.7-14) for KRAS G12C, 4.8 (3.4-6.7) for KRAS non-G12C and 8.5 (7.3-10.6) for wild-type KRAS genotypes (p = 0.23). Median OS were 18.4 (12.6-NR), 20.6 (11.4-NR) and 27.1 (18.7-34.2) months, respectively (p = 0.57)., Conclusion: No difference in efficacy was observed in non-squamous aNSCLC patients treated with first-line pembrolizumab immunotherapy whether they presented a KRAS G12C, non KRAS G12C or wild-type KRAS genotype., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2022 Elsevier B.V.
