RESUMO
The effectiveness of a fluorescent analysis in the diagnosis of gastric cancer was studied in 280 patients. Fluorescence of a tumor was noted in 87% of cases. Dependence of fluorescence of a tumor on its sizes was revealed: in tumor diameter less than 1 cm, fluorescence was revealed in 94% of cases, more than 4 cm--in 76%. In infiltrative growth, only 74% of tumors were fluorescent. To define the possibility of the use of a fluorescent analysis in the differential diagnosis of gastric diseases, 490 patients with presumptive diagnosis of chronic gastritis, gastric ulcer disease, polyposis were examined. In diagnosis of +malignant polyps in 91.5% of cases, results of the fluorescent analysis concurred with the findings of histologic study. Probability of establishing the correct diagnosis by the data of fluorescent analysis in ulcer disease is equal to 87.5%, in chronic gastritis--86%.
