Purpose: Genomic profiling is a major component for first-line treatment decisions in patients with non-small cell lung cancer (NSCLC) and the timeliness of biomarker testing is essential to improve time to treatment initiation (TTI) or avoid inappropriate treatment.

Patients And Methods: The phase III LIBELULE trial (NCT03721120) included patients with radiological suspicion of advanced lung cancer. They were randomized (1:1), the control arm receiving diagnostic procedures according to each center's practice and the liquid biopsy arm with additional testing performed at the first visit using the InVisionFirst®-Lung assay.

Background: Durvalumab, an anti-PD-L1 immune checkpoint inhibitor, after radio-chemotherapy (RCT) has changed the management of locally advanced non-small cell lung cancer (LA NSCLC). A series of retrospective studies have investigated different cut-off of lymphocyte count (LyC) and neutrophil-to-lymphocyte ratio (NLR) to predict survival in LA NSCLC. None of these studies has validated their threshold in an independent group of patients.

Article Synopsis
  • The KRAS protein switches between active (GTP-bound) and inactive (GDP-bound) states, and mutations (especially KRASG12C) can keep it in the inactive state, promoting cancer cell growth primarily in lung adenocarcinomas.
  • Sotorasib and adagrasib are the first drugs that target this inactive state, but resistance to these treatments is common.
  • Resistance mechanisms can be classified as "on-target" (new mutations in KRAS) or "off-target" (changes in other genes or processes), indicating a need for more extensive studies to uncover these adaptive changes in cancer treatment.

Background: Immune checkpoint inhibitors (ICIs) have become standard-of-care at different stage disease in non-small cell lung cancer (NSCLC). Based on the increasing characterization of molecular aberrations and oncogenic drivers in NSCLC, it is expected that more and more patients will benefit from orally small targeted therapies in NSCLC. However, their concomitant or sequential use is associated with an increased risk of a various toxicity pattern.

gain-of-function mutations are frequently observed in sporadic arteriovenous malformations. The mechanisms underlying the progression of such -driven malformations are still incompletely understood, and no treatments for the condition are approved. Here, we show the effectiveness of sotorasib, a specific KRAS G12C inhibitor, in reducing the volume of vascular malformations and improving survival in two mouse models carrying a mosaic G12C mutation.

EGFR exon 20 (EGFR Ex20) insertion mutations in non-small cell lung cancer (NSCLC) are insensitive to traditional EGFR tyrosine kinase inhibitors (TKIs). Mobocertinib is the only approved TKI specifically designed to target EGFR Ex20. We performed an international, real-world safety and efficacy analysis on patients with EGFR Ex20-positive NSCLC enrolled in a mobocertinib early access program.

Mutationsin epidermal growth factor receptor (EGFR) are found in approximately 48% of Asian and 19% of Western patients with lung adenocarcinoma (LUAD), leading to aggressive tumor growth. While tyrosine kinase inhibitors (TKIs) like gefitinib and osimertinib target this mutation, treatments often face challenges such as metastasis and resistance. To address this, we developed physiologically based pharmacokinetic (PBPK) models for both drugs, simulating their distribution within the primary tumor and metastases following oral administration.

Targeting EGFR alterations, particularly the L858R (Exon 21) mutation and Exon 19 deletion (del19), has significantly improved the survival of lung cancer patients. From now on, the issue is to shorten the time to treatment. Here, we challenge two well-known rapid strategies for testing: the cartridge-based platform Idylla™ (Biocartis) and a digital droplet PCR (ddPCR) approach (ID_Solution).

Lung adenocarcinoma (LUAD) is associated with a low survival rate at advanced stages. Although the development of targeted therapies has improved outcomes in LUAD patients with identified and specific genetic alterations, such as activating mutations on the epidermal growth factor receptor gene (EGFR), the emergence of tumor resistance eventually occurs in all patients and this is driving the development of new therapies. In this paper, we present the In Silico EGFR-mutant LUAD (ISELA) model that links LUAD patients' individual characteristics, including tumor genetic heterogeneity, to tumor size evolution and tumor progression over time under first generation EGFR tyrosine kinase inhibitor gefitinib.

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.

  • A study on Stage IVa thymoma, a rare cancer, evaluated the effects of subtotal pleurectomy and HITHOC treatment on patients with either de novo tumors or distant relapses.
  • The research analyzed 40 patients over 24 years, finding a hospital mortality rate of 2.5% and significant differences in disease-free intervals between de novo tumors (49 months) and distant relapses (85 months).
  • The study concludes that HITHOC combined with pleurectomy may yield favorable outcomes for selected patients, but more multicentric research is necessary to establish it as a standard treatment.

Background: The absence of diagnosis of acute respiratory distress syndrome (ARDS) concerns 20% of cancer patients and is associated with poorer outcomes. Diffuse pneumonic-type adenocarcinoma (P-ADC) is part of these difficult-to-diagnose ARDS, but only limited data are available regarding critically ill patients with diffuse P-ADC. We sought to describe the diagnosis process and the prognosis of P-ADC related ARDS patients admitted to the intensive care unit (ICU).

Article Synopsis
  • Lung cancer screening often leads to the discovery of small pulmonary nodules that may require surgery to determine if they are cancerous; the study investigated the effectiveness of video-assisted thoracoscopic surgery (VATS) in these cases.* -
  • A comprehensive analysis of 651 patients who had surgery for suspicious pulmonary nodules revealed that those who underwent VATS had significantly more wedge resections, while thoracotomy patients were more frequently diagnosed with lung cancer.* -
  • Although VATS resulted in a higher rate of surgical procedures for benign lesions, the overall occurrence of lobectomies for benign conditions was not significantly different compared to traditional thoracotomy techniques.*

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.

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.

More than 35% of lung adenocarcinoma patients have bone metastases at diagnosis and have a poor survival. Periostin, a carboxylated matrix protein, mediates lung cancer cell dissemination by promoting epithelial-mesenchymal transition, and is involved in bone response to mechanical stress and bone formation regulation. This suggests that periostin may be used as a biomarker to predict survival in lung cancer patients.
