Paper Abstract

The performance of a fluorescence imaging device was compared with conventional white-light bronchoscopy in 100 patients with lung cancer, 46 patients with resected State I nonsmall cell lung cancer, 10 patients with head and neck cancer, and 67 volunteers who had smoked at least one pack of cigarettes per day for twenty-five years or more. Using differences in tissue autofluorescence between premalignant, malignant and normal tissues, fluorescence bronchoscopy was found to detect more than twice as many moderate-severe dysplasia and carcinoma in situ sites than conventional white-light bronchoscopy. The use of fluorescence imaging to detect small peripheral lung nodules was investigated in a micro metastatic lung model of mice implanted with Lewis lung tumor cells. Fluorescence imaging was found to be able to detect small malignant lung lesions. The use of (delta) -aminolevulinic acid (ALA) to enhance fluorescence detection of CIS was investigated in a patient after oral administration of 60 mg/kg of ALA four hours prior to bronchoscopy, although ALA enhanced the tumor's visibility, multiple sites of false positive fluorescence were observed in areas of inflammation or metaplasia.
