Fluorescent Light Bronchoscopy Plus White Light Bronchoscopy for Early Detection of Lung Cancer

Study Overview
=================
Brief Summary
-----------------
RATIONALE: Fluorescent bronchoscopy, when used in combination with conventional white light bronchoscopy, may improve the ability to detect early lung cancer. PURPOSE: A pilot study to evaluate fluorescent light bronchoscopy plus conventional bronchoscopy as a tool for screening and detecting lung cancer in persons with completely resected head and neck cancer or successfully treated early-stage lung cancer.

Detailed Description
-----------------
OBJECTIVES: Evaluate the efficacy of autofluorescence bronchoscopy using the Lung Imaging Fluorescence Endoscopic System with conventional white-light bronchoscopy for the early detection of lung cancer in selected patients with known or suspected bronchogenic carcinoma, completely resected head and neck cancer, and successfully treated early-stage lung cancer. Determine the number of areas of moderate dysplasia, severe dysplasia, and carcinoma in situ in patients treated with surgery for lung cancer compared with patients treated with combined modality therapy. Determine the ability of immunohistochemistry to predict whether lesions of moderate to severe dysplasia will progress to cancer. OUTLINE: If possible, patients produce a 3-day pooled sputum sample prior to bronchoscopy. Patients then undergo tracheobronchial white-light bronchoscopy followed by autofluorescence bronchoscopy using the Lung Imaging Fluorescence Endoscopic (LIFE) Device attached to a computerized video camera. Visualized tissue is classified as either normal, abnormal, or suspicious. Abnormal or suspicious tissue is biopsied, as is tissue from 1 or 2 randomly chosen normal sites. Immunohistochemical analysis of the biopsy material is conducted without knowledge of the bronchoscopic results. Patients unable to produce a sputum sample prior to bronchoscopy are required to do so after bronchoscopy. PROJECTED ACCRUAL: A total of 70 patients will be entered.
