Hepatocellular carcinoma (HCC) is prevalent globally, linked to hepatitis B (HBV) and C (HCV) infections. Early diagnosis and understanding molecular causes like HBX and aflatoxin are key to managing this liver cancer.

Area of Science:

  • Hepatology and Oncology
  • Molecular Biology
  • Infectious Diseases

Background:

  • Hepatocellular carcinoma (HCC) is a significant global health issue, particularly in tropical Africa and Southeast Asia, primarily linked to chronic hepatitis B virus (HBV) infection.
  • Rising incidence in other regions like Japan, Europe, and the USA is associated with chronic hepatitis C virus (HCV) infection, often stemming from past blood product usage.
  • Molecular studies have identified key factors in hepatocarcinogenesis, including the HBX gene in HBV, HCV core protein, and specific genetic mutations linked to aflatoxin exposure.

Purpose of the Study:

  • To review the current understanding of hepatocellular carcinoma (HCC) epidemiology, etiology, and pathogenesis.
  • To discuss diagnostic challenges related to precancerous lesions and early carcinoma detection.
  • To explore potential therapeutic avenues and diagnostic advancements for HCC.

Main Methods:

  • Literature review of molecular biological studies on hepatocarcinogenesis.
  • Analysis of epidemiological data on HCC prevalence and trends.
  • Discussion of diagnostic criteria and advancements, including the use of liver-specific antibodies.

Main Results:

  • Chronic HBV and HCV infections are major drivers of HCC globally.
  • Specific molecular mechanisms, such as HBX gene involvement and aflatoxin-induced mutations, are implicated in liver cancer development.
  • Diagnostic uncertainties persist regarding precancerous lesions, while new diagnostic tools like liver-specific antibodies show promise.

Conclusions:

  • Effective prevention strategies like infant vaccination for HBV are crucial but long-term solutions.
  • Continued research into molecular mechanisms and diagnostic improvements is essential for combating HCC.
  • Emerging treatments, including immunotherapy, may offer new hope for reducing HCC recurrence post-surgery.
