Non Small Cell Lung Cancer
Conditions
Brief summary
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

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Diagnostic accuracy of the CLE-based score for non-small cell lung cancer (NSCLC) detection | During the endoscopic procedure and confirmed after biopsy analysis (up to 7 days) | Proportion of cases in which the CLE imaging score correctly identifies NSCLC, using standard histopathology from biopsy samples as the reference standard |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Improvement of biopsy yield using CLE imaging criteria | During the endoscopic procedure and confirmed after pathology analysis (up to 7 days) | Proportion of biopsy samples considered adequate for histopathological diagnosis when guided by CLE imaging features. |
| Identification of NSCLC histological subtypes using CLE imaging | During the procedure and confirmed after biopsy analysis (up to 7 days) | Accuracy of CLE imaging criteria in differentiating NSCLC subtypes (e.g., squamous cell carcinoma, adenocarcinoma, carcinoid tumors) compared with standard histopathology. |
