Introduction. Hepatocellular cancer is the most frequent primary malignant neoplasm of the liver, developing against the background of viral hepatitis, alcohol abuse, metabolic disorders, cirrhosis. Most often hepatocellular cancer is diagnosed at late stages of the disease, when patients are no longer subject to specific treatment. The priority method of treatment of early stages remains surgical. In the absence of cirrhosis or with compensated cirrhosis the best option is liver resection, in other cases orthotopic liver transplantation is performed. However, when hepatocellular cancer is diagnosed, most patients fall outside the Milan criteria, and the bridge to orthotopic liver transplantation is down-stage therapy. Bridge therapy is used to treat hepatocellular cancer while awaiting liver transplantation and aims to prevent stage progression. The probability of progression of hepatocellular cancer after orthotopic liver transplantation within the first two years is about 75% and about 10% is detected after the fourth year. Progression of hepatocellular cancer remains the main factor limiting the life expectancy of patients after orthotopic liver transplantation.The aim of the study: to evaluate the results of antitumor treatment of patients with hepatocellular cancer progression after liver transplantation.Materials and methods. We evaluated the results of treatment of 50 patients with hepatocellular cancer progression after orthotopic liver transplantation, who were treated on the basis of FGBU NMI Center of Oncology named after N.N. Blokhin. N.N. Blokhin Oncology Center in the period from 2009 to 2020. We analyzed and evaluated overall and recurrence-free survival depending on the bridge therapy, type of treatment, presence of vascular invasion and portal vein thrombosis.Results. According to the results of bridge therapy, hepatocellular cancer stage progression was observed in 9 patients, stabilization - in 17 patients, partial/complete response - in 9 patients. The median recurrence-free survival of patients who received bridge therapy and down-stage therapy was 23.6 months; among patients who did not, it was 35.6 months. The median overall survival with surgical treatment was 79.8 months, whereas with radiation therapy it was 17.2 months.
