Objectives: The aim of this study was to evaluate the sensitivity and specificity of autofluorescence bronchoscopy (AFB) according to the macroscopic appearance of airway lesions under white light bronchoscopy (WLB). Materials and Methods: The bronchoscopic findings of 708 patients, who were pathologically and clinically diagnosed with airway lesions and underwent both WLB and AFB, were analyzed. Results: We recruited 708 patients for this study, of which 336 (47.5%) had benign lesions; 300 and 254 benign lesions were detected by AFB (specificity, 89.3%) and WLB (specificity, 75.6%), respectively. In 372 (52.5%) patients with bronchiogenic carcinoma, 356 and 235 lesions were identified by AFB (sensitivity, 95.7%) and WLB (sensitivity, 63.2%), respectively. The sensitivity and specificity of AFB for diagnosing lung cancer were higher than those of WLB (P < 0.05). Moreover, AFB showed high sensitivity for detecting lung cancer in cases in which WLB revealed hyperplasia, infiltration, and stenosis (P < 0.05). Conclusions: AFB combined with WLB could effectively improve the diagnosis of airway lesions.
