About this trial

The purpose of the study is to describe confocal laser endomicroscopy (CLE) interpretation criteria for different types of peripheral pulmonary lesions (PPLs), with histopathological correlation, and to perform the validation of these criteria.

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

Patients older than 18 years.

Chest CT shows peripheral pulmonary lesions (peripheral pulmonary lesions are lesions beyond the segmental bronchi that are invisible during bronchoscopy), and transbronchial biopsy is considered necessary and feasible.

Patients who have good compliance and sign informed consent.

Disqualifiers

Patients with known allergy for fluorescein.

Pregnant or lactating women.

Patients with contraindications of bronchoscopy.

The investigators believe that patient has other conditions that are not suitable for the study.

Trial population

Patients with peripheral pulmonary lesions scheduled for transbronchial lung biopsy.

Trial outcomes

Primary outcomes

1

Diagnostic accuracy of CLE in differential diagnosis of benign and malignant PPLs

Diagnostic accuracy is defined as the number of lesions correctly identified as malignant or benign using our proposed CLE interpretation criteria divided by the total number of lesions.

Time frame
6 months post-procedure

Secondary outcomes

1

Sensitivity, specificity of CLE in differential diagnosis of benign and malignant PPLs

Sensitivity is defined as the number of lesions correctly identified as malignant using our proposed CLE interpretation criteria divided by the total number of malignant lesions. Specificity is defined as the number of lesions correctly identified as benign using our proposed CLE interpretation criteria divided by the total number of benign lesions.

Time frame
6 months post-procedure
2

positive predictive value, and negative predictive value of CLE in differential diagnosis of benign and malignant PPLs

The positive predictive value is the percentage of true malignant lesions among all lesions identified as malignant using our proposed CLE interpretation criteria. The negative predictive value is the percentage of true benign lesions among all lesions identified as benign using our proposed CLE interpretation criteria.

Time frame
6 months post-procedure
3

Diagnostic accuracy of CLE in differential diagnosis of different types of PPLs

Different types of PPLs include different types of common malignant PPLs (e.g., adenocarcinoma, squamous cell carcinoma, small cell lung carcinoma, etc.) and different types of common benign PPLs (e.g., inflammation, tuberculosis, fungal infection, etc.). Diagnostic accuracy is defined as the number of lesions correctly identified as a specific disease using our proposed CLE interpretation criteria divided by the total number of lesions.

Time frame
6 months post-procedure
4

Incidence of complications

Complications mean a composite of procedure related adverse advents during and after the operation.

Time frame
1 month post-procedure
