Abstract
Photoelectric detection of fluorescence from hematoporphyrin-containing 'occult' bronchogenic carcinoma is a potentially useful technique for localizing and delineating such cancers. A method is presented which would enable use of a fluorescence-detection system simultaneously with conventional illumination during flexible bronchofiberscopic examination. Preliminary data suggest that quantities of hematoporphyrin as small as 5 picograms can be detected on the surface of tumors by this method.
