White light (WL) bronchoscopy is a procedure which allows the airway to be examined for cancer. It is one of multiple tools used for staging and diagnosis of lung cancer.
While conventional bronchoscopy can be used to stage early lung cancer, even doctors experienced in bronchoscopy find detecting pre-cancerous lesions to be difficult. In an effort to improve detection, theEndoscopic Light Source and Video Camera may be used with bronchoscopes during endoscopic examination to illuminate and acquire real-time images of the lung or other hollow organs.
Theconsists of an endoscopic light source and video camera. It can operate in two modes:
Light-induced fluorescence endoscopy (FL), when used as an adjunct to WL, has been demonstrated to improve the sensitivity for detection of pre-invasive and invasive lesions in the lung. A recent multi-center study usingdemonstrated that WL+FL bronchoscopy using this device was 1.33 times more sensitive than WL alone in detecting disease, and 4.25 times more sensitive than WL specifically in detecting pre-invasive lesions.
Physicians at both NYU Medical Center and Bellevue Hospital routinely use this method to evaluate the airway for otherwise undetected cancers, improving the early detection and treatment of lung cancer.
