Non-Small Cell Lung Cancer (NSCLC) Clinical Trials

The goal of this observational study is to evaluate whether confocal laser endomicroscopy (CLE) can improve the real-time diagnosis of non-small cell lung cancer (NSCLC) in patients undergoing bronchoscopic biopsy for suspected lung tumors. The main questions it aims to answer are: * Can a high-specificity CLE-based score accurately identify NSCLC during endoscopic procedures? * Can CLE imaging criteria improve biopsy yield and help differentiate histological subtypes (e.g., squamous cell carcinoma, adenocarcinoma, carcinoid tumors)? Participants will: * Undergo standard bronchoscopic navigation procedures with additional real-time imaging using CLE and biopsy * Have CLE findings compared with standard histopathological analysis of biopsy samples
