摘要

Hepatocellular carcinoma (HCC) is a leading cause of cancer-related mortality worldwide, with chronic infections by hepatotropic viruses such as hepatitis B virus (HBV), and hepatitis C virus (HCV), being major risk factors. Chronic infections with these viruses are the leading cause of HCC worldwide, with HBV alone responsible for over 50% of cases. Despite advances in direct-acting antivirals (DAAs) for HCV and nucleos(t)ide analogues (NAs) for HBV, challenges remain in HCC prevention, early detection, and treatment. Recent research highlights the role of viral-induced metabolic alterations, such as the Warburg effect, mitochondrial dysfunction, and lipid dysregulation, in promoting HCC. Moreover, immune checkpoint inhibitors have emerged as effective treatments for advanced HCC, though responses vary between HBV- and HCV-related cancers. Additionally, novel therapeutic approaches and metabolic-targeted therapies offer promising avenues for virus-associated HCC treatment. Advancements in liquid biopsy biomarkers and artificial intelligence-driven diagnostics are improving HCC surveillance and risk stratification, potentially enabling earlier interventions. While HBV vaccination has significantly reduced HCC incidence, disparities in global vaccination coverage persist. Furthermore, antiviral therapies combined with structured surveillance programs have proven effective in reducing HCC incidence and mortality. This review highlights the complex connection between viral, genetic, and environmental factors in HCC development and underscores the importance of integrated prevention strategies to reduce its burden globally.
