The relevance of this scientific article is dictated by the fact that currently malignant tumors of the gastrointestinal tract occupy a large share in the structure of oncological diseases. In addition, they are often diagnosed at late stages due to the duration of the asymptomatic period of the disease and patients seek specialized medical institutions al ready with the active spread of metastases, therefore, the study of the features of the blood supply of malignant neoplasms of this localization, first of all, allows us to determine the factors that should be influenced during treatment in order to prevent and predict further spread of the tumor process. The purpose of this study is to analyze experimental data to identify the features of the blood supply of tumors localized in the organs of the gastrointestinal tract and their impact on the course of the disease.
