Background: The purpose of this study was to evaluate combined autofluorescence (AF) and narrow band imaging (NBI) for detection of mucosal lesions additional to known primary head and neck cancers and to determine impact on management.
Methods: Patients with head and neck cancer requiring preoperative screening or posttreatment surveillance had white light (WL), AF and NBI inspection of the head and neck and bronchus. Known primary cancers were not analyzed, only additional lesions. Moderate dysplasia or worse was considered significant.
Results: In all, 73 patients were recruited. Respectively, there were 24 and 18 additional lesions in the head and neck and bronchus that had significant histopathology. In both regions, AF and NBI were more sensitive than WL for detecting significant dysplasia with NBI demonstrating better specificity than AF (p = .003); 11 of 73 patients (15.1%) had additional findings detected by AF and NBI, which had an impact on management.
Conclusion: Combined AF and NBI inspection is highly specific at panendoscopy and can influence management.
