Abstract

Hepatocellular carcinoma (HCC) remains one of the predominant causes of cancer-related mortality across the globe. It is attributed to obesity, excessive alcohol consumption, smoking, and infection by the hepatitis virus. Early diagnosis of HCC is essential, and local treatments such as surgical excision and percutaneous ablation are effective. Palliative systemic therapy, primarily with the tyrosine kinase inhibitor Sorafenib, is used in advanced cases. However, the prognosis for advanced HCC remains poor. This Review additionally describes the pathophysiological mechanisms of HCC, which include aberrant molecular signaling, genomic instability, persistent inflammation, and the paradoxical position of the immune system in promoting and suppressing HCC. The paper concludes by discussing the growing body of research on the relationship between mitochondria and HCC, suggesting that mitochondrial dysfunction may contribute to the progression of HCC. This Review focuses on immunological interactions between different mechanisms of HCC progression, including obesity, viral infection, and alcohol consumption.

Major risk factors of hepatocellular carcinoma (HCC), including viral infections such as HBV and HCV, diabetes, obesity and other metabolic dysfunctions, alcohol consumption (30 g/day for males and 20 g/day for females), and environmental toxins such as aflatoxin-B1.

Drugs employed to treat advanced stages of HCC in primary and secondary care settings. Primary care medicines are the first-line therapy used when advanced HCC is diagnosed. Secondary care medicines are used when the first treatments are no longer effective or the disease develops following an initial response (PD-L1, programmed death ligand 1; VEGF, vascular endothelial growth factor).
