Purpose. To determine the feasibility of meta-analysis about pancreatic tumors in Russian scientific literature.	1 - A.V. Vishnevsky Insti-tute of Surgery. 2 - I.M. Sechenov First Moscow State Medical University. Moscow, Russia.

Materials and methods. We searched the scientific electronic library eLIBRARY.RU on query "diagnostic imaging of pancreatic neoplasms". Out of 2444 publications, 1202 were in open access. In total, 34 articles were selected with consequent analysis of sections "Materials and Methods" and "Results and Discussion". Results. Out of 34 analyzed articles, only 13 (38%) had sufficient sample size (more than 100 patients). Demographic characteristics were reflected as follows: gender was indi-cated in 22 (64.7%) articles, age - in 24 (70.5%) publications. The most frequent pancreatic lesions described were ductal adenocarcinoma and neuroendocrinal neoplasms (NEN) (11 articles - 29.7% each), followed by serous cystadenoma, intraductal papillary mucinous ne-oplasm (IPMN) (7 articles - 18.9% each), mucinous cystadenoma and SPPN/SPP-carcinomas (6 articles - 16.2% each). The most common methods for pancreatic tumor imaging were MSCT with intravenous contrast enhancement (88.0%) and transabdominal ultrasound (79.0%) with MRI (61.8%) and endoscopic ultrasound (56.0%) used less frequently. The most frequent diagnostic combination was transabdominal ultrasound and MSCT, in some cases supplemented with MRI. Conclusion. Data of Russian publications is comparable to the world literature. With the goal of meta-analysis in mind, it is advisable to increase the observation period (include larger number of patients), clearly define patient gender and their age in the "Materials and Methods" section (for subsequent comparison of data), use generally accepted statistical pa-rameters and analyze causes of false-positive and false-negative results via pathomorpholog-ical studies.
