Objective: to improve the oncological and direct results of treatment of patients with stage IV colorectal cancer by studying the prognosis of treatment response based on molecular markers of redox status of tumor progression. Parenchymal conservation surgery in patients with colorectal cancer with liver metastases affecting the central sites of the liver is an effective and oncologically safe method. Severe postoperative complications in the groups of central liver sites and peripherally localized metastases were 24.4% and 21.8%, respectively (p = 0.15), and overall 3-year survival was (53 ± 9)% and (59 ± 15). )%, (p = 0.3). It was found that the formation of metastatic microenvironment in the liver is provided by the generation of superoxide radicals and NO-activation of gelatinases MMP-2, which remodel the intercellular matrix in the parenchyma of the operated liver. The rate of generation of superoxide radicals in the adjacent to metastasis and distant liver parenchyma was (1.09 ± 0.19) nmol / g of raw tissue ∙ min and (0.36 ± 0.03) nmol / g of raw tissue ∙ min, p <0.01). The activity of MMP-2 in the adjacent to metastasis and distant relatively healthy parenchyma of the operated liver was respectively (6.88 ± 1.31) in. at. and (3.73 ± 0.60) y. o., (p <0.01). The study showed that the use of preconditioning with sevoflurane in patients during liver resection did not significantly affect the functional capacity of the liver. Further research is needed to include more patients. Product Description popup.authors Sikachev Sergey S. Burlaka Anton A. Ganul Andrey V. Zakalska Khrystyna А. Zubarev Nikolay G.
