Opportunities in Diagnostics of Pancreatic Metastatic Tumors by Cytological Method

Abstract

Our study includes results of 152 pancreatic fine needle aspirations of solid and cystic tumors, from 149 patients of the N.N. Petrov Cancer Research Center for the 3-year period (2016 - 2018). Representative cell material for morphological studies was obtained in 97.4% of cases. The results of cytological examination of 111 patients with pancreatic tumors were compared with histological data. The effectiveness of cytological examination was 96.1%, sensitivity - 95.6%, specificity -100%. Metastatic lesions were presented in 9% (9 patients). In 9 diagnostically proven cases, the cytological result was correct 8 times. Cytological examination with immunocytochemistry is a valid and accurate diagnostic procedure for the evaluation of pancreatic tumors including metastatic lesions.
