Hepatitis B Virus-Associated Hepatocellular Carcinoma

Area of Science:

• Hepatology
• Virology
• Oncology

Background:

• Hepatitis B virus (HBV) is a DNA virus causing liver disease and hepatocellular carcinoma (HCC).
• Chronic HBV infection can lead to liver cirrhosis, a significant risk factor for HCC.
• Concurrent Hepatitis D virus (HDV) infection exacerbates HBV-related liver disease and complications.

Purpose of the Study:

• To review the association between HBV infection and HCC development.
• To explore the molecular mechanisms underlying HBV-induced hepatocarcinogenesis.
• To discuss current management and treatment strategies for HBV-related HCC.

Main Methods:

• Review of existing scientific literature on HBV, HCC, and related molecular pathways.
• Analysis of the role of HBV proteins, such as HBx, in oncogenesis.
• Comparison of molecular profiles of HBV-HCC and HDV-HCC.

Main Results:

• HBV infection is linked to HCC risk via direct and indirect oncogenetic mechanisms.
• Altered molecular pathways and DNA damage contribute to HBV-associated hepatocarcinogenesis.
• The HBx protein plays a crucial role in the oncogenetic process.
• Distinct molecular profiles exist for HBV-HCC and HDV-HCC.

Conclusions:

• HBV infection significantly increases the risk of developing HCC, with or without cirrhosis.
• Understanding the molecular basis of HBV-HCC is critical for effective management.
• Comprehensive management includes HCC surveillance, viral suppression, and personalized treatment strategies considering viral etiology.
