The Role of Narrow Band Imaging Videobronchoscopy in Lung Cancer (NBI)
Narrow band imaging (NBI) videobronchoscopy is an optical technique in which filtered light enhances superficial neoplasm based on their neoangiogenic pattern. The objectives of this study investigate its better diagnostic yield in the assessment of lung cancer than conventional flexible bronchoscopy.

Time Perspective: Prospective
|Official Title:||The Diagnostic Yield of Narrow Band Imaging Videobronchoscopy in Lung Cancer|
- accuracy of NBI videobronchoscopic biopsy [ Time Frame: 10-11 months ] [ Designated as safety issue: No ]Define and compare the sensitivity, specificity, positive predictive value, negative predictive value, likelihood ratio and accuriacies for the diagnostic techniques for lung cancer.
- early cancer lesion detection rate using Shibuya descriptors [ Time Frame: 10-11 months ] [ Designated as safety issue: No ]Define and compare the sensitivity, specificity, positive predictive value, negative predictive value, likelihood ratio and accuriacies for the diagnostic techniques for early lung cancer.

Inspection with high resolution endoscopy was followed by NBI. Detected lesions were biopsied. applied the system of shibuya et al. to analyze and classify vascular patterns by NBI into four categories (spiral and screw pattern, dotted pattern, tortuous pattern, avascular pattern) compared with the known diagnostic yield of conventional white light bronchoscopy, An equivalent or superior result will also significantly impact on patient care This technology could aid not only early-stage lung cancer diagnosis but also more accurate local staging of lung cancer.
