Abstract
The aim of the work was to assess the possibility of the cytological method in the diagnosis of epithelial liver tumors and to determine the cytomorphological criteria in the differential diagnosis of liver carcinomas. The authors analyzed the data of 106 fine-needle aspiration biopsies and 167 smears-prints during cor-biopsy of masses of the liver in patients who were examined at the polyclinic of the oncological dispensary in Nizhny Novgorod in 2016. - 2017 As a result, full-fledged material for cytological examination in the form of smears-prints from cor-biopsy and fine-needle aspiration biopsies was obtained in 75.4% (n=126) and 95.2% (n=101), respectively. The great possibilities of the cytological method are shown: an affirmative diagnosis of the presence of primary or metastatic liver lesions was made in 88.8% (n=112) based on smears of sorbiopsy prints and in 87.1% (n = 88) with fine-needle aspiration biopsies. Typical cytomorphological criteria for primary and metastatic liver carcinomas made it possible to determine the origin of the primary tumor in 56.6% of cases (n=98).
