Abstract

Background: Hepatocellular Carcinoma (HCC) arises in chronic liver diseases, particularly caused by hepatitis C virus (HCV) and alcohol in Europe. We aimed at evaluating the characteristics and mortality of patients with HCV-related HCC as compared to other HCC etiologies.

Methods: We retrospectively evaluated data from 887 patients with HCC identified through the Hospital del Mar Cancer Registry (Barcelona, Spain), during the 2001-2020 period. We estimated crude and adjusted hazard ratios (aHR) of dying and its 95% confidence interval (95%CI).

Results: Among 887 patients with HCC, 617 (69.6%) were HCV-infected. Underlying cirrhosis was more frequent in HCV-related HCC compared to other etiologies (97% vs. 89%, p < 0.001). The prevalence of HCV-related HCC decreased from 79% in 2001-2005 to 55% in 2015-2020 (p < 0.001). HCV infection did not increase the hazard of death [aHR 0.95 (CI95% 0.81-1.13)]. Mortality was independently related to age > 75 years, advanced BCLC stage at diagnosis, and diagnosis before 2010.

Conclusion: In our cohort, HCV-related HCC frequently occurred in a cirrhotic background, but showed similar clinical characteristics and mortality as compared to other HCC etiologies.
