[Stratification of the risk of malignization of intraductal papillary mucinous neoplasms of the pancreas].

The purpose of this review was to analyze the most perspective methods for risk stratification of malignant transformation of pancreatic intraductal papillary mucinous neoplasms (IPMN). Advisability of humoral predictors (tumor markers, inflammatory markers, circulating leptin and branched-chain amino acids, etc.) is in identifying prognostic signs suitable for risk stratification of IPMN malignant transformation and, therefore, determining treatment strategy for a particular patient. According to data screening, the most advisable predictors of malignant transformation of neoplasms are carbohydrate antigen 19-9, carcinoembryonic antigen, neutrophil-to-lymphocyte ratio and high-grade dysplasia. At the same time, DNA sequencing, analysis of miRNA and telomere expression, as well as liquid biopsy have a high potential and require further research for routine clinical practice.
