Features of the Composition of Cytokines of Various Biological Effects in Patients with Uveal Melanoma: Analysis of Blood Serum. Part 2

Abstract

Purpose. Conduct extended analysis of cytokine status and its role in inflammatory processes in uveal melanoma based on multiplex analysis of blood serum.Patients and methods. Immunological studies of blood serum and lacrimal fluid were performed in 80 patients with uveal melanoma and 38 healthy donors (control group). The average age of the surveyed was 53.7 ± 12.2 years. Group 1 included 32 patients with small-sized choroidal melanoma (T1NoMo), group 2 consisted of 26 patients with medium-sized tumors (T2NoMo), group 3 — 22 patients with large tumor size (T3NoMo). Cytokine content was determined in blood serum by the method of multiplex analysis on the xMAP platform in the Luminex xPONENT 3.1 program using 47 plex kits (ProcartaPlex, eBioscience, Austria).Results. In blood serum — increase of pro-inflammatory (LIF, RANTES, IP-10), anti-inflammatory (TGF-1β), proliferative (IL-15), pro-tumor (EGF), angiogenic (PIGF-1 and SDF-1α) cytokines compared with control group, p < 0.05.Conclusion. In response to the manifestation and growth of uveal melanoma, many chemoattractant mediators of proinflammatory, angiogenic, proliferative action are produced that promote metastasis. The study of cytokines at the systemic level in serum leads to a deeper understanding of the pathophysiology of carcinogenesis and to facilitate the development of targeted therapies for inhibiting tumor growth.
