Liver transplantation (LTx) is the best treatment for patients with early-stage hepatocellular carcinoma (HCC). The Milan criteria positively influenced results of liver transplantation and were adopted by the majority of cancer centers, becoming the criterion standard treatment for early-stage HCC. Despite the use of restrictive criteria, recurrence is still high, affecting between 8% and 20% of cases, and is a significant predictor of survival after LTx. The diagnosis of both micro-and macro-invasion of vessels, which are significant factors in determining the frequency of recurrence and overall survival, significantly decreases the success of transplantation, causing an increase in mortality of 50% in comparison to recipients with no vascular invasion. The risk of recurrence depends on several factors, which are discussed in this review. The authors also discuss the clinical presentation and treatment methods of recurrence and its prognosis. In addition, the role of different models developed to identify groups of patients with high versus low risk of recurrence is discussed, enabling the planning of recommendations and screening protocols after transplantation to help early diagnosis and guide effective treatment. In the era of an increasing numbers of liver transplants due to HCC, the need to create robust screening tools is urgent.

Background The mortality caused by hepatocellular carcinoma is expected to rise in the upcoming decade. Sorafenib has become the preferred systemic treatment option in patients with unresectable HCC. This study aimed to present the median overall survival (OS) in a group of patients with advanced HCC, treated with sorafenib in Poland between 2011 and 2019. Material/Methods The analyzed group of patients was qualified for treatment with sorafenib, financed by the National Health Fund, based on the guidelines of the Polish Drug Program. Kaplan-Meier method was used to plot the OS curves, and the log-rank test was used for testing. Multivariate assessment of factors (sex and age) related to the time to death of the patient was done using Cox regression. Results Of the 2072 treated patients, 75% were men (1556) and 25% were women (516). The minimum age of patients in the trial group was 18 years and the maximum age was 90 years. Among the 1556 analyzed cases in males, 27.44% (427) did not end with death (by the date of completing the analysis). The percentage of one-year survival for this population was 58.16%, and the 2-, 3-, and 5-year survival rates were 34.45%, 21.81%, and 9.72%, respectively. The percentage of censored cases in the 516 females was 25.78% (133). The 1-2-, 3-, and 5-year survival for this population was 59.30%, 36.27%, 22.47%, and 11.34%, respectively. Statistical tests did not reveal a significant difference in the curve profiles by sex. There were no associations between OS and age. Conclusions Systemic treatment with sorafenib in accordance with the presented criteria allows for very good results, comparable to the results of selected groups of patients presented by other authors.

Background Hepatitis B and C viruses have been recognized as undoubtedly carcinogenic to humans. In the Polish population, where most people are protected by HBV vaccinations, hepatocellular carcinoma (HCC) and its main cause, persistent HCV infection, significantly affect the demand for liver transplantations. Material/Methods The purpose of this study was to categorize the number of primary liver transplantations in Poland in the years 2001–2017 by cause and to analyze changes in LTx indications during this period. Data were sourced from POLTRANSPLANT, the Organization and Coordination Center for Transplantation in Poland. Additionally, we compared the numbers of HCC cases and hepatitis B and C cases during this period. Results In the analyzed period, in Poland, 3332 primary liver transplantations were performed. Overall, 44% (1456) of LTx cases were combined with HBV and/or HCV and/or HCC. In this group, transplants in patients with only 1 specific factor – HCV – formed the largest cohort, accounting for about 40% (581) of cases. Transplants in patients who only had HBV and in those who only had HCC accounted for 12% (185) and 5% (69), respectively. Conclusions The analyzed data suggest that HCV infections are a significant public health problem in Poland, as is also reflected by the growing number of LTx performed due to HCC. To limit the numbers of HCV and HCC cases, immediate implementation of a Polish National Program against HCV should be considered.
