Abstract
The development of the tumor process involves the involvement of various functional elements of innate and adaptive immunity. A special role in the reorganization of tissues, changes and evolution of the properties of cancer cells is given to cytokines, the study of the role of which in these processes with various types of neoplasms and, in particular, with nonmetastatic gastric cancer is an urgent task.
The aim of the work was to determine the characteristics of the cytokine status in the tissues of patients with non-metastatic gastric cancer.
Materials and methods. In the extracts of tumor tissue, perifocal zone, omentum, peritoneum of patients with gastric cancer without metatstases (T3-4aN0-3M0, n = 20, 58.9 ± 9.7 years), the concentration of IL-1P, IL-2, IL -6, IL-8, IL-18, TNF-a, IL-10 and IL-1RA in tumor tissue, the perifocal zone, as well as in the omentum and peritoneum.
Results and discussion. In the tumor tissue, an increase in the content of IL-1P, IL-8 and a decrease in IL-2, TNF-a and IL-10 were noted. In the perifocal zone, a decrease in the concentration of IL-1P, IL-6, IL-8 was revealed with an increased content of IL-2, IL-1RA, IL-10, TNF-a and IL-18. Against this background, the omentum and peritoneum compared with the tumor, the concentration of IL-1P, IL-18 and IL-1RA is reduced, against the background of an increase in the concentration of IL-2, IL-6, TNF-a and IL-10.
Findings. It was shown that tumor tissue has some features in the cytokine profile compared with unaffected tissues, which can be used to further evaluate the development of the pathological process.
