Uncommon mutational landscape in a non-small cell lung cancer patient treated with crizotinib: Case report.

Background: exon 14 (ex14) skipping mutations are oncogenic drivers observed in approximately 3-4% of non-small cell lung cancers (NSCLC). Several distinct genetic alterations leading to METex14 have been reported but clinical significances of rare mutations are not well defined as well as outcomes of patients upon MET inhibitors (METi).

Case Presentation: This report presents the case of a patient with metastatic NSCLC harboring an uncommon mutational landscape including notably a novel ex14 mutation (R1022L).

Real-life clinical management patterns in extensive-stage small cell lung cancer across France: a multi-method study.

Background: We designed this study based on both a physician practice survey and real-world patient data to: (1) evaluate clinical management practices in extensive-stage small cell lung cancer (ES-SCLC) among medical centers located across France; and (2) describe first-line treatment patterns among patients with ES-SCLC following the introduction of immunotherapy into clinical practice.

Methods: A 50-item questionnaire was completed by physicians from 45 medical centers specialized in SCLC management. Responses were collected from June 2022 to January 2023.

Incidence of venous thromboembolism and association with PD-L1 expression in advanced non-small cell lung cancer patients treated with first-line chemo-immunotherapy.

Background: Venous thromboembolism (VTE) is a serious complication in non-small cell lung cancer (NSCLC) patients. The use of thromboprophylactic therapy is subject to an accurate assessment of the VTE risk depending on patients, tumor characteristics and type of systemic antineoplastic treatments. However, little is known concerning the risk of VTE in patients suffering from an advanced NSCLC treated with first-line chemo-immunotherapy and the impact of tumor biomarkers such as PD-L1 expression.

Case Report: Coronaro-bronchial fistula vascularizing a squamous cell lung cancer.

Coronary fistulas are rare, having been described for the first time by Krauss in 1865 in postmortem. They are commonly asymptomatic and can be caused by congenital or acquired malformations. We present the case of a 65-year-old patient who was treated for squamous cell lung cancer with chemoimmunotherapy and presented with angina.

Clinical Characteristics of Patients with Advanced ALK-Translocated Non-small Cell Lung Cancers and Long-Term Responses to Crizotinib (CRIZOLONG GFPC 05-19 Study).

Background: Although ALK-translocated (ALK+) advanced non-small cell lung cancers (aNSCLCs) are currently treated with second- or third-generation ALK inhibitors (ALK-TKIs), some patients respond durably to the first-generation ALK-TKI crizotinib.

Objective: This study aimed to describe the clinical characteristics of these long-term responders.

Patients And Methods: This national, multicenter, retrospective, non-interventional study included patients with ALK+ aNSCLCs and long-term responses to first (L1)- or subsequent (≥ L2)-line crizotinib, defined, respectively, as treatments lasting > 18 and > 10 months.

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).

Real-life second-line epirubicin-paclitaxel regimen as treatment of relapsed small-cell lung cancer: EpiTax study.

Background: Few therapeutic options are approved as second-line treatment after failure of platinum-based chemotherapy for patients with extensive-stage small-cell lung cancer (ES-SCLC). Topotecan widespread use remains challenged by the risk of severe toxicities in a pretreated population. Little is known about the efficacy and safety of epirubicin-paclitaxel doublet in second-line and beyond and especially cerebral outcomes.

Paclitaxel-bevacizumab combination in advanced non-squamous non-small-cell lung cancer (NSCLC): AVATAX, a retrospective multicentric study.

Introduction: Compared with docetaxel, the phase-III trial, ULTIMATE, showed a significant improvement of progression-free survival (PFS) with paclitaxel-bevacizumab combination (PB) as second- or third-line treatment in advanced non-small cell lung cancer (NSCLC). With the increase of immunotherapy treatment in first-line settings, the optimal treatment after first-line failure must be redefined.

Methods: This multicentric retrospective study identified all advanced NSCLC patients treated with PB as second-line therapy and beyond.

Brigatinib for Pretreated, ALK-Positive, Advanced Non-Small-Cell Lung Cancers: Long-Term Follow-Up and Focus on Post-Brigatinib Lorlatinib Efficacy in the Multicenter, Real-World BrigALK2 Study.

Brigatinib is a next-generation ALK inhibitor (ALKi) that shows efficacy in ALK inhibitor naïve and post-crizotinib ALK+ advanced NSCLCs (aNSCLCs). The efficacy of brigatinib was retrospectively assessed in patients with aNSCLCs included in the brigatinib French Early-Access Program (1 August 2016−21 January 2019). The primary endpoint was investigator-assessed progression-free survival (invPFS) and the primary analysis was updated in 2021 with a longer follow-up, focused on post-brigatinib lorlatinib efficacy.

Lorlatinib for advanced anaplastic lymphoma kinase-positive non-small cell lung cancer: Results of the IFCT-1803 LORLATU cohort.

Background: Anaplastic lymphoma kinase (ALK)-rearranged (ALK+) non-small cell lung cancer (NSCLC) represents a rare subset of lung cancer, with specific presentation, and multiple treatment options, including selective tyrosine kinase inhibitors (TKIs). Real-world evidence is insufficient regarding the actual real-life treatment sequences in the late line setting, and available clinical trials may not reflect real-world situation. Here, we took advantage of the French Expanded Access Program (EAP) of lorlatinib, a third-generation TKI targeting ALK and ROS1, to assess treatment sequencing, and lorlatinib efficacy and safety, in patients with ALK+ NSCLC.

Henoch-Schönlein Purpura Associated with Lung Cancer: When Paraneoplastic Manifestations Impede Oncological Management.

Background: Henoch-Schönlein purpura (HSP) is an uncommon syndrome that mostly occurs in children, in whom it is frequently triggered by infections. In contrast, HSP in adults is more frequently of neoplastic origin. .

Durvalumab-induced lesions of bronchiolitis and fully reversible bronchiectasis in a patient with non-small cell lung cancer: A case report.

Durvalumab is a humanized monoclonal antibody targeting programmed cell death ligand-1 (PD-L1), leading to an antitumor activity, used as consolidation therapy in patients with locally advanced unresectable non-small cell lung cancer (NSCLC). Several immune-related adverse events (irAEs) have previously been described in patients following treatment with immune checkpoint inhibitors (ICIs). To the best of our knowledge, we report the first case of immunotherapy-induced fully reversible bronchiolitis and bronchiectasis, despite the fact that its pathophysiological mechanism has been previously considered to be irreversible.

Thyroid dysfunction induced by immune checkpoint inhibitors is associated with a better progression-free survival and overall survival in non-small cell lung cancer: an original cohort study.

Background: The objective of this study was to investigate the association between the onset of TD and treatment efficacy in NSCLC patients who initiated anti-PD-1 blockade (Nivolumab) and to assess the impact of TD severity and subtype on nivolumab efficacy.

Materials And Methods: This study was performed at a referral oncology center between July 20, 2015 and June 30, 2018. Patients with histologically confirmed stage IIIB/IV NSCLC in progression after one or two lines of treatment and who initiated Nivolumab were included.

Duration of nivolumab for pretreated, advanced non-small-cell lung cancer.

Background: A standard of care for pretreated, advanced non-small-cell lung cancers (NSCLCs), nivolumab has demonstrated long-term benefit when administered for 2 years. We aimed to better discern an optimized administration duration by retrospectively analyzing real-life long-term efficacy in a prospective cohort.

Methods: All nivolumab-treated adults with advanced NSCLCs (01/09/2015 to 30/09/2016) from nine French centers were eligible.

Encephalitis related to immunotherapy for lung cancer: Analysis of a multicenter cohort.

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).

First-line pembrolizumab for non-small cell lung cancer patients with PD-L1 ≥50% in a multicenter real-life cohort: The PEMBREIZH study.

Background: The KEYNOTE-024 trial demonstrated that pembrolizumab, a PD-1 inhibitor, significantly improves progression-free survival (PFS) and overall survival (OS) in selected patients with previously untreated advanced non-small cell lung cancer (NSCLC) with a PD-L1 tumor proportion score (TPS) ≥50% and without EGFR/ALK aberrations. The main aim of this study was to report the efficacy and safety profile of pembrolizumab in real-life conditions.

Method: This was a French retrospective multicenter longitudinal study of 108 consecutive patients with advanced NSCLC, a PD-L1 TPS ≥50% and without EGFR/ALK aberrations who were treated by pembrolizumab, in first line.
