DOI: 10.61718/khimu2025978-617-7886-88-3https://dspace.khimu-library.com.ua/handle/123456789/453This first study on ROS1 gene alterations in Azerbaijani non-small cell lung cancer (NSCLC) patients retrospectively analyzed 110 cases diagnosed between 2019 and 2023. ROS1 rearrangements were identified in 12 patients (10.9%) using RT-PCR, a rate higher than the global 1–2%, likely due to selection bias. ROS1-positive patients were predominantly female (58.3%) and non-smokers (75%), aligning with international data. The majority were diagnosed at advanced stages (66.7%). The median overall survival was short (8.13 months), attributed to limited access to ROS1-targeted tyrosine kinase inhibitors. The study highlights the urgent need for routine molecular screening and improved access to targeted therapy to enhance diagnostic precision and clinical outcomes in Azerbaijan.enlung cancernon-small cell lung cancerros1 rearrangementtargeted therapyoverall survivalAzerbaijanMolecular and clinical significance of ROS1 gene alterations in lung cancer patients: a retrospective analysis from Azerbaijan (2019–2023)Article
