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.
Methods: We retrospectively reviewed data on 201 advanced stage NSCLC patients who were referred to our laboratory for RNA-based molecular evaluation of ALK, ROS1, RET, NTRK gene rearrangements as well as MET exon 14 skipping.
Results: Overall, 23 (11.4%) positive cases were retrieved. Regarding molecular assessment, 11 (5.5%), 2 (1.0%), 9 (4.5%), and 1 (0.5%) out of 201 harbored an ALK, ROS1, RET gene rearrangement, or MET exon 14 skipping, respectively.
Conclusions: In this study, we provide real-world experience on RNA-based NGS analysis in patients with advanced stage NSCLC.

Introduction: This study aimed to assess the feasibility of implementing the Idylla system, an ultra-rapid, cartridge-based assay, as an extension of rapid on-site evaluation (ROSE) in cytology. The authors conducted a pilot validation study on specimens from non-small cell lung carcinoma, thyroid carcinoma, and melanoma, evaluating four assays designed to detect alterations in KRAS, EGFR, BRAF, gene fusions, and expression imbalances in ALK, ROS1, RET, NTRK1/2/3, and MET exon 14 skipping transcripts. They investigated the feasibility of providing accurate biomarker molecular testing results in a cytopathology laboratory within hours of specimen collection.

Introduction: Programmed death-ligand 1 (PD-L1) is the main predictive biomarker used to identify patients with NSCLC who are eligible for treatment with immune checkpoint inhibitors. Despite its utility, the predictive capacity of PD-L1 is limited, necessitating the exploration of supplementary predictive biomarkers. In this report, we describe the prognostic value of / mutation status for overall survival (OS) in patients with NSCLC treated with first-line immunotherapy or combined chemoimmunotherapy.

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.
