Summary

BACKGROUND It is estimated that around 71 milion people live with chronic hepatitis C virus (HCV) infection. This may lead to the development of liver cirrhosis and hepatocellular carcinoma (HCC). Liver cirrhosis is considered as one of the most common risk factors of hepatocellular carcinoma (HCC). HCC is seventh most common cancer worldwide. The treatment of HCV with direct-acting antivirals (DAAs) has led to the increase of sustained virological response (SVR) rates to more than 90%. It is suggested that the virus eradication reduces, but not eliminates the risk of HCC. This concerns especially patients with liver cirrhosis or previous HCC history. There are reports of early occurrence of HCC after the DAA treatment. Therefore, patients undergoing successful HCV treatment should be monitored for the possibility of hepatoccelular carcinoma occurrence.

AIM OF THE STUDY In this study the investigators aimed to assess the occurrence of HCC after direct acting antiviral HCV treatment and evaluate whether the course of HCC and liver function differ among the population of patients treated with DAAs and those who were not receiving the therapy with DAA.

MATERIAL AND METHODS This is the observative, cohort, retrospective study which will be performed in several clinical centres in Poland. The inclusion criteria are: hepatocellular carcinoma diagnosis, age >18 years old.

The investigators will collect both epidemiological (age, gender, comorbidities, alcohol abuse) and clinical data (serum bilirubin, alanine, aspartate aminotransferase, platelets, gammaglutamyltransferase, alkaline phosphatase and alpha-fetoprotein level, Child-Pugh and MELD score, imaging tests, liver biopsy and elastography, if performed).

In all patients, the HCV infection and co-infections will be assessed. In those who underwent the DAA treatment, the composition of the therapy and response to the treatment will be evaluated.

Statistical analysis will be performed in subgroups of patients undergoing DAA treatment and without the therapy. The distribution of continuous variables will be analysed by the Shapiro-Wilk test. Quantitative data will be analysed using the Mann-Whitney U test or Kruskal-Wallis ANOVA when appropriate. Qualitative data will be compared using the χ² test or the Fisher exact test. Correlations between quantitative variables will be assessed using the Spearman correlation coefficient. P value will be set at <0.05.
