Early detection of bronchial lesions using lung imaging fluorescence endoscope.
The performance of the Lung Imaging Fluorescence Endoscope (LIFE) system was compared with conventional bronchoscopy in 158 patients: 68 patients with invasive cancer, 42 patients with abnormal sputum cytology findings (12 early cancer and 26 dysplasia), 17 cases with resected lung cancer and 31 smokers with symptoms. The respective results of conventional bronchoscopy and LIFE for detection of dysplasia were; sensitivity 52% and 90% (biopsy basis), 62% and 92% (patient basis). Fluorescence bronchoscopy may be an important adjunct to conventional bronchoscopy to improve the localization of subtle lesions of bronchus.
