Aim of the study: Hepatocellular carcinoma (HCC) is the most common type of primary liver cancer, with poor treatment outcomes often because of delayed diagnosis. The aim of this study was to assess the co-incidence of cirrhosis, alcohol abuse, hepatitis B virus (HBV) or hepatitis C virus (HCV) infection and fatty liver disease in patients in the population of north-eastern Poland, to analyse the usefulness of α-fetoprotein (AFP) in the diagnosis of HCC and to assess the effectiveness of HCC treatment in this group.
Material and methods: The study involved 104 patients diagnosed with HCC. The age, sex, comorbidities, HCC risk factors and levels of AFP were analysed. The effect of antiviral therapy of HCV and HBV on HCC development was observed and the effectiveness of therapies used in the treatment of HCC was assessed.
Results: Over 90% of patients with HCC were older than 45 years. The incidence of HCC was higher in men than in women. Patients with HCC were also diagnosed with cirrhosis (72%), alcohol abuse (35%), HCV infection (35%), HBV infection (24%), and fatty liver disease (13%). HCC developed in 9/25 (36%) patients positive for HBV despite effective antiviral therapy. The highest AFP levels were found in HBV-positive patients. The mean survival time was 19 months for partial hepatectomy and 16 months for thermal ablation.
Conclusions: The main predisposing factor for HCC is cirrhosis, followed by alcohol abuse and infection with HCV. Effective antiviral therapy for HBV does not prevent the development of HCC in all cases. Since 29% of patients were disqualified from HCC treatment due to an advanced stage of cancer, it indicates insufficient screening for HCC. Partial hepatectomy and radiofrequency ablation show comparable effectiveness in the treatment of HCC.
