Abstract

The availability of modern high-precision diagnostic methods increased the detection rate of pancreatic neuroendocrine neoplasia (pNEN). There is no doubt concerning the necessity of surgical treatment for localized functioning tumors, whilecurrently there is no objective way to choose the tactic for non-functioning asymptomatic neuroendocrine tumors of the pancreas (pNET) with the exception of the tumor size.Treatment tactics for non-functioning asymptomatic T1 neuroendocrine tumors (less 2 cm in size) are debatable. According to literature surgical treatment for lesions less than 2 cm does not always increase survival. In the same time even in high-volume centers pancreatic surgery shows high morbidity and mortality rate. Prospective randomized trials comparing surveillance and operative treatment are not published yet, as far as authors concerned. International guidelines answer the question of treatment such neoplasms ambiguously, while national Russian recommendations do not cover the topic. Guidelines are based on heterogeneous retrospective studies; therefore, the aim of scientific research is to determine reliable criteria for patient selection for dynamic observation or surgical treatment.This article provides an overview of 60 scientific publications covering the problem.
