About this trial

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

Trial outcomes

Primary outcomes

1

Diagnostic accuracy of the CLE-based score for non-small cell lung cancer (NSCLC) detection

Proportion of cases in which the CLE imaging score correctly identifies NSCLC, using standard histopathology from biopsy samples as the reference standard

Time frame
During the endoscopic procedure and confirmed after biopsy analysis (up to 7 days)

Secondary outcomes

1

Improvement of biopsy yield using CLE imaging criteria

Proportion of biopsy samples considered adequate for histopathological diagnosis when guided by CLE imaging features.

Time frame
During the endoscopic procedure and confirmed after pathology analysis (up to 7 days)
2

Identification of NSCLC histological subtypes using CLE imaging

Accuracy of CLE imaging criteria in differentiating NSCLC subtypes (e.g., squamous cell carcinoma, adenocarcinoma, carcinoid tumors) compared with standard histopathology.

Time frame
During the procedure and confirmed after biopsy analysis (up to 7 days)
