Abstract

Purpose of the study improving the diagnosis of precancerous diseases and cancer of the oral mucosa using fluorescent immunocytochemical studies by direct immunofluorescence. A clinical laboratory examination of 111 patients was carried out: 46 patients with squamous cell carcinoma of the oral mucosa, 35 people with precancerous lesions (17 leukoplakia, 18 - oral lichen planus) and 30 healthy people. All patients underwent a traditional cytological examination and an additional immunocytochemical examination by direct immunofluorescence, the expression levels of tumor markers P53, P16 and Ki67 were determined. The data were compared with the results of histological analysis. As a result of the study, it was revealed that in patients with cancer, the expression of oncomarker P53 was four times higher than in patients with precancerous pathology. In 6.52% of cases, co-expression of markers Ki67 and P16 was found. Thus, the advantages of fluorescent immunocytochemical diagnostics were the absence of invasive traumatic intake of the biomaterial in the patient, reduction in the timing of obtaining the result, high sensitivity, and the possibility of remote evaluation of the results. Therefore, that increases the accessibility of the method, and the possibility of using this method for a screening study of population.
