Raman Spectroscopic Analysis of Bronchoscopic Biopsy for Diagnosing Lung Cancer

Raman Spectroscopic Analysis of Bronchoscopic Biopsy for Diagnosing Lung Cancer

The goal of this clinical trial is to evaluate raman spectroscopic analysis of bronchoscopic biopsy for diagnosing lung cancer in visible lesions in the airway. The main question it aims to answer are: the diagnostic efficacy raman spectroscopic analysis of bronchoscopic biopsy for diagnosing lung cancer.

The bronchoscopic biopsy sample of patients with visible lesions in the airway would undergo raman spectrum analysis.

Inclusion Criteria:

• Patients who plan to undergo bronchoscopic biopsy or EBUS-TBNA
• Visible intratracheal lesions under bronchoscope
• Non-visible lesions suspected of lung cancer

Exclusion Criteria:

• The patient could not tolerate further examination aimed at clarifying the cause of the disease or refused to accept further examination aimed at clarifying the cause of the disease due to poor general condition, serious organ dysfunction, etc
• The patient has no definite diagnosis
