Abstract:
In this paper, we reported the method and the results of the intrinsic fluorescence of tumor tissue bring out by using N2-laser and mercury lamp.25 patients and 14 resected specimens were studied.Among the 25 patients, there were 20 cases revealing orange color fluorescence under above lights, and Were confirmed to be malignant by biopsy.The peak wave length of the fluorescenc was between 6000 A and 6200A, while blue-white fluorescenc in normal tissue, benign tumor and chronic inflammation (5 cases)had wave length of 4600 A to 4800 A.The results of 14 resected specimens were similar to those patient's.The cancer tissue will appear a fluorescence of specific spec- trum when excited by appropriate light.It provide a new method for the early diagnosis of malignant tumor.We also discussed the mechanism, the advantages and the light source of the method.
