Real-Time Imaging to Improve Lung Cancer Diagnosis : Comparing Confocal Laser Endomicroscopy (CLE) With Standard Biopsy for Quicker and Safer Detection of Non-Small Cell Lung Cancer

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

Inclusion Criteria: * Patient for whom endobronchial navigation-guided biopsy is indicated * Complete medical data (CLE images and histopathological results) Exclusion Criteria: * Persons referred to in Articles L. 1121-5, L. 1121-7, and L. 1121-8 of the French Public Health Code: * Individuals under 18 years of age * Adult persons subject to legal protection measures (guardianship, curatorship, or judicial protection) * Adult persons unable to express their consent * Persons deprived of liberty by judicial or administrative decision, and persons receiving psychiatric care under Articles L. 3212-1 and L. 3213-1
