The aim of this study was to analyse the clinico-pathological characteristics and outcomes of a cohort of French patients who were prospectively screened for Anaplastic Lymphoma Kinase (ALK) rearrangement. One hundred and sixteen consecutive patients screened for ALK rearrangement to be recruited into a crizotinib registration trial were included from eight French centres. ALK rearrangement was detected by fluorescence in situ hybridization. Seventeen patients (14.6%) were positive for ALK. ALK+ patients were younger (p = 0.049) and more likely to be males (p=0.032), non- or light-smokers (p = 0.048) and without underlying respiratory disease (p=0.025) compared to ALK- patients. Thyroid-transcription factor-1 expression was present in all ALK+ tumours. ALK+ tumours tended to have lymph node and brain metastases. In multivariate analyses, gender, smoking history and N stage were independently associated with ALK status. Median overall survival (OS) was not reached for ALK+ patients and was significantly longer than for ALK- patients (hazard ratio for death for ALK- patients 2.98; 95% CI [1.29-6.90], p=0.01). French ALK+ patients present a specific phenotype. ALK rearrangement should be determined to improve OS with an effective targeted therapy.

Objective: ALK, ROS1, NTRK, and RET gene fusions and MET exon 14 skipping alterations represent fundamental predictive biomarkers for advanced non-small cell lung cancer (NSCLC) patients to ensure the best treatment choice. In this scenario, RNA-based NGS approach has emerged as an extremely useful tool for detecting these alterations. In this study, we report our NGS molecular records on ALK, ROS1, NTRK, and RET gene fusions and MET exon 14 skipping alterations detected by using a narrow RNA-based NGS panel, namely SiRe fusion.

Introduction: The transcriptomic characteristics of + non-small cell lung cancer (NSCLC) represent a crucial aspect of its tumor biology. These features provide valuable insights into key dysregulated pathways, potentially leading to the discovery of novel targetable alterations or biomarkers.
Methods: From The Cancer Genome Atlas (TCGA) and the Gene Expression Omnibus (GEO) databases, all available + (n = 10), + (n = 5) and + (n = 5) NSCLC tumor and + cell line (n = 7) RNA-sequencing files were collected.

Background: Anaplastic lymphoma kinase () rearrangement, the most common oncogenic rearrangement in lung adenocarcinoma, occurs in approximately 5% of non-small cell lung cancer (NSCLC) patients. gene is the most common partner of rearrangement, and distinct EML4-ALK fusions differ in their responsiveness to ALK tyrosine kinase inhibitors. However, the concurrence of two rearrangements in one patient and whose response to ALK-TKIs have rarely been reported so far.

Background: Given advancements in adjuvant treatments for non-small-cell lung cancer (NSCLC) with epidermal growth factor receptor (EGFR) and anaplastic lymphoma kinase (ALK)-targeted therapies, it is important to consider postoperative targeted therapies for other early-stage oncogene-addicted NSCLC. Exploring baseline outcomes for early-stage NSCLC with these rare mutations is crucial.
Objectives: This study aims to assess relapse-free survival (RFS) and overall survival (OS) in patients with resected early-stage NSCLC with rare targetable driver mutations.

Background: Patients with ALK-rearranged non-small cell lung cancer (ALK+ NSCLC) with symptomatic brain (BM) and leptomeningeal (LM) metastases are underrepresented in clinical trials due to poor performance status. Additionally, the need for improved and validated assessment criteria for evaluating central nervous system (CNS) response remains critical. Lorlatinib has demonstrated systemic activity in patients with ALK+ NSCLC.
