Background: Capmatinib is a selective MET inhibitor with demonstrated efficacy in a phase II study of non-small cell lung cancer (NSCLC) patients harboring METex14 mutations. However, the real-world outcomes of capmatinib are largely unknown. From June 2019, the French Early Access Program (EAP) provided capmatinib to METex14 NSCLC patients who were ineligible for or for whom first-line standard therapies had failed., Methods: IFCT-2104 CAPMATU was a multicenter study that included all METex14 NSCLC patients who received capmatinib as part of the EAP until August 2021. The primary endpoints were time to treatment failure (TTF), progression-free survival (PFS), overall survival (OS) and objective response rate (ORR)., Results: A total of 146 patients were included. The median age was 74.9 years, 56.6 % were never-smokers, and 32.4 % had brain metastases. The median TTF, median PFS and median OS from capmatinib initiation were 5.1 months (95 % CI 4.2-6.0), 4.8 months (95 % CI 4.0-6.0) and 10.4 months (95 % CI 8.3-13.2), respectively. Evaluation of the best response to capmatinib was available for 134 patients and resulted in an ORR of 55.3 % (95 % CI 46.8 %-63.6 %). The median PFS was 7.7 months for treatment-naïve patients and 6.0 and 4.1 months for patients who had received one or 2 + prior lines of treatment, respectively. For patients with brain metastases, the median PFS was 3.0 months. Capmatinib had a known and manageable safety profile, with grade 3 to 4 adverse events, mostly peripheral edema (8.2 %), occurring in 17.8 % of patients., Conclusion: In this large real-world study of METex14 NSCLC patients, the efficacy of capmatinib was confirmed, with a manageable safety profile, even in patients with brain metastases and in those who received several lines of treatment. This study reinforces the key role of capmatinib for these patients., Competing Interests: Declaration of competing interest The authors declare the following financial interests/personal relationships which may be considered as potential competing interests: M.

Introduction: Sequential anti-programmed cell death protein 1 (PD-1) or anti-programmed death-ligand 1 (PD-L1) followed by small targeted therapy use is associated with increased prevalence of adverse events (AEs) in NSCLC. KRASG12C inhibitor sotorasib may trigger severe immune-mediated hepatotoxicity when used in sequence or in combination with anti-PD-(L)1. This study was designed to address whether sequential anti-PD-(L)1 and sotorasib therapy increases the risk of hepatotoxicity and other AEs., Methods: This is a multicenter, retrospective study of consecutive advanced KRAS G12C -mutant NSCLC treated with sotorasib outside clinical trials in 16 French medical centers. Patient records were reviewed to identify sotorasib-related AEs (National Cancer Institute Common Classification Criteria for Adverse Events-Version 5.0). Grade 3 and higher AE was considered as severe. Sequence group was defined as patients who received an anti-PD-(L)1 as last line of treatment before sotorasib initiation and control group as patients who did not receive an anti-PD-(L)1 as last line of treatment before sotorasib initiation., Results: We identified 102 patients who received sotorasib, including 48 (47%) in the sequence group and 54 (53%) in the control group. Patients in the control group received an anti-PD-(L)1 followed by at least one treatment regimen before sotorasib in 87% of the cases or did not receive an anti-PD-(L)1 at any time before sotorasib in 13% of the cases. Severe sotorasib-related AEs were significantly more frequent in the sequence group compared with those in the control group (50% versus 13%, p < 0.001). Severe sotorasib-related AEs occurred in 24 patients (24 of 48, 50%) in the sequence group, and among them 16 (67%) experienced a severe sotorasib-related hepatotoxicity. Severe sotorasib-related hepatotoxicity was threefold more frequent in the sequence group compared with that in the control group (33% versus 11%, p = 0.006). No fatal sotorasib-related hepatotoxicity was reported. Non-liver severe sotorasib-related AEs were significantly more frequent in the sequence group (27% versus 4%, p < 0.001). Severe sotorasib-related AEs typically occurred in patients who received last anti-PD-(L)1 infusion within 30 days before sotorasib initiation., Conclusions: Sequential anti-PD-(L)1 and sotorasib therapy are associated with a significantly increased risk of severe sotorasib-related hepatotoxicity and severe non-liver AEs. We suggest avoiding starting sotorasib within 30 days from the last anti-PD-(L)1 infusion., (Copyright © 2023 International Association for the Study of Lung Cancer. Published by Elsevier Inc.

Introduction: Systemic nocardiosis is an infectious disease that is rarely associated with mediastinal lymph nodes., Case Report: We report the case of a 72-year-old male patient treated with a high dose of oral corticosteroids for rheumatoid polyarthritis. This patient presented with rapid overall deterioration associated with mediastinal lymph nodes. Endobronchial ultrasound enabled us to establish a diagnosis of systemic nocardiosis. The patient recovered after having received suitable antibiotic treatment for four months., Conclusion: This work reports on a rare clinical presentation of systemic nocardiosis associated with mediastinal lymphadenopathies and highlights the key role of endobronchial ultrasound in diagnosing mediastinal lymph nodes, especially in differential diagnosis for lung cancer., (Copyright © 2022 SPLF.

Introduction: ROS1-rearranged (ROS1+) non-small-cell lung cancer (NSCLC) is a rare lung cancer with limited treatment options. Phase I-II studies with ROS1-tyrosine kinase inhibitors (TKIs) included small numbers of patients and real-world data are lacking. We investigate the efficacy and safety of lorlatinib, a third-generation TKI targeting ALK and ROS1, in patients with ROS1+ NSCLC treated through an expanded access program., Methods: Consecutive patients with advanced ROS1+ NSCLC treated with lorlatinib between October 2015 and June 2019 were included. Data were collected from medical records. The primary endpoint was progression-free survival., Results: Out of the 80 patients included, 47(59%) were female, 49(62%) never smokers (less than 100 cigarettes over the lifetime), and 68(85%) had stage IV NSCLC at diagnosis. Most frequent histology was adenocarcinoma (95%) and median age was 58.2 years. At the time of lorlatinib initiation, 51(64%) patients had brain metastases and 55(81%) were PS 0-1. Lorlatinib was administered as second/third/fourth/fifth+ line in 29%/28%/18%/26% of patients. All patients previously received at least one ROS1 TKI, and 55(69%) previously received chemotherapy. Median follow-up from lorlatinib initiation was 22.2 months. Median progression-free survival and overall survival from lorlatinib initiation were 7.1 months [95% confidence interval (CI) 5.0-9.9 months] and 19.6 months (95% CI 12.3-27.5 months). Median duration of treatment with lorlatinib was 7.4 months (95% CI 6.5-13.1 months). Overall response and disease control rates were 45% and 82%, respectively. The central nervous system response rate was 72%. Treatment was stopped due to toxicity in 10 patients (13%). The safety profile was consistent with previously published data., Conclusions: Lorlatinib is a major treatment option for advanced refractory ROS1+ NSCLC in treatment strategy., Competing Interests: Role of the funder The funding source had no role in the design, data collection, analysis, or interpretation of the study, or in the preparation of this manuscript.

Introduction: Using immune-checkpoint inhibitors (ICIs) to manage cancer is associated with various immune-related adverse events. Central and/or peripheral neurological disorders are rare and potentially serious. We analyzed the characteristics of non-small-cell lung cancer (NSCLC) patients who developed immune-related encephalitis under anti-programmed-death protein-1 or its ligand (PD-1/PD-L1)., Methods: Clinical, biological and radiological characteristics of ICI-treated NSCLC patients with immune-related encephalitis, from 6 centers, were evaluated retrospectively., Results: The 6 centers included 9 patients: all men, all smokers, median (range) age 67 (48-77) years, 78% adenocarcinomas, first- or second-line ICI for 5 and 4 patients, respectively. Two patients had non-active cerebral metastases at ICI onset. A median of 5 (1-22) ICI infusions preceded neurological symptoms, the most frequent being confusion (78%), fever (45%) and cerebellar ataxia (33%). CSF analyses revealed a median white blood cell count of 22/mm 3 (1-210/mm 3 ), with hyperlymphocytosis in 8 patients and high protein levels in all. All bacteriological and virological analyses were negative. Cerebral MRI was considered normal for 5 patients; 4 patients had FLAIR hypersignals consistent with brain parenchyma inflammation. Three patients required intensive care. All patients received corticosteroids (different doses), a median of 8.5 (6-18) days post-onset. Corticosteroids achieved rapid symptom regression without sequelae in 8 patients. The last patient, with the longest time until corticosteroid introduction, died. ICIs were never restarted in any patient., Conclusion: Immune encephalitis, a rare but serious complication of anti-PD-1/PD-L1 therapy, carries a good prognosis when managed with early corticosteroids., Competing Interests: Declaration of Competing Interest This research did not receive any specific grant from funding agencies in the public, commercial or not-for-profit sectors., (Copyright © 2020.

Background: The prognosis of patients with non-small cell lung cancer (NSCLC) who develop leptomeningeal metastasis (LM) is poor., Objective: To assess the clinical efficacy of osimertinib, a third-generation tyrosine-kinase inhibitor (TKI), in patients with epidermal growth-factor receptor (EGFR)-mutated NSCLCs and LM., Patients and Methods: Retrospective study of NSCLC patients with osimertinib-treated EGFR-mutated NSCLC and LM., Results: Twenty patients (mean age, 61.2 years; 70% women) with adenocarcinoma NSCLC were included in the study. EGFR mutations were reported in exons 18 (n = 2), 19 (n = 7), and 21 (n = 11). Before starting osimertinib, patients had received a mean of 2.3 treatment lines. When LM was diagnosed, all patients had clinical symptoms. Sixteen (80%) patients had a performance status ≥2. At osimertinib initiation, 13 (65%) patients harbored the EGFR-T790M-resistance mutation. Osimertinib was started at 80 (n = 17), 160 (n = 2), or 40 mg/day (n = 1). All 13 (100%) patients with the T790M mutation and 4 (57%) of those without it obtained clinical responses. Among the 11 radiologically assessable patients, 9 (82%) responded, with 5 responses reported within 15 days after treatment initiation. Median overall survival and progression-free survival were 18.0 and 17.2 months, respectively, from the start of osimertinib., Conclusions: In this non-selected population, osimertinib had remarkable efficacy in NSCLC patients with LM irrespective of the presence of the EGFR-T790M-resistance mutation. Osimertinib efficacy was rapid in several patients, even some with poor performance status.

Introduction: Percutaneous transthoracic needle biopsy is a useful and common procedure in the investigation of a lung nodule. The occurrence of air embolism after percutaneous transthoracic needle biopsy is extremely rare., Case Report: We report a 62-year-old woman who presented with neurological signs including restlessness, meningeal signs and focal neurologic deficits 4 hours after percutaneous transthoracic lung biopsy, related to air embolism. The outcome was favorable with hyperbaric oxygen therapy., Conclusion: Percutaneous transthoracic needle biopsy complicated by air embolism has been rarely reported. It usually occurs within minutes after the biopsy. The late onset of this adverse event in our patient is exceptional. Air embolism occurs more frequently after biopsy of lung infiltrates compared to nodules. Occurrence of a pneumothorax or an intraalveolar haemorrhage following a percutaneous transthoracic needle biopsy may be warning manifestations and justify a close monitoring., (Copyright © 2012 Société nationale Française de médecine interne (SNFMI).
