Endoscopic endosonography with fine-needle aspiration biopsy in the diagnosis of pancreatic tumors
Objectives of the study: efficiency assessment of cytological methods in the diagnosis of pancreatic tumors. Material and methods. Our study includes results of 163 pancreatic fine needle aspirations of solid and cystic tumors, from 160 patients of the N.N. Petrov Cancer Research Center for the 4-year period (2016-2020). Results. Representative cell material for morphological studies was obtained in 98.6% of cases. The results of cytological examination of 35 patients with pancreatic tumors were compared with histological data. Malignant process was correctly established in 30 out of 32 patients, benign process- in all three cases. The sensitivity of cytological examination was 93.1%, specificity - 100%. Conclusion. Pancreatic fine-needle aspiration cytology is safe, rapid, accurate and cost-beneficial modality of investigation of pancreatic mass lesion.
