Insights

Preventing liver cancer from chronic hepatitis B (CHB) involves vaccination, antiviral therapies to suppress viral replication, and regular screening. Early detection and treatment are key to improving outcomes for hepatocellular carcinoma (HCC).

Area of Science:

  • Hepatology
  • Oncology
  • Virology

Background:

  • Chronic hepatitis B (CHB) is a leading cause of hepatocellular carcinoma (HCC), responsible for about 50% of cases.
  • Hepatitis B virus (HBV) infection poses a significant global health burden, necessitating effective prevention strategies.

Purpose of the Study:

  • To review primary, secondary, and tertiary preventive measures against HBV-related HCC.
  • To highlight the importance of vaccination, antiviral treatments, and surveillance in HCC prevention.

Main Methods:

  • Literature review of primary, secondary, and tertiary prevention strategies for HBV-related HCC.
  • Analysis of the efficacy of vaccination, antiviral therapies (interferon, nucleos(t)ide analogs), and surveillance methods.

Main Results:

  • Universal hepatitis B vaccination is the most effective primary prevention method, significantly reducing HBV infection and HCC rates.
  • Antiviral treatments and suppression of HBV DNA levels are crucial for preventing progression to cirrhosis and HCC.
  • Periodic surveillance (ultrasonography, α-fetoprotein) aids early HCC detection for curative treatment.
  • Adjuvant interferon prevents early recurrence post-resection, while nucleos(t)ide analogs show promise for late recurrence prevention through viral suppression.

Conclusions:

  • A multi-faceted approach including vaccination, antiviral therapy, and surveillance is essential for preventing HBV-related HCC.
  • Optimal preventive strategies require further investigation to address early and late recurrence effectively.

Hepatitis01:25

Hepatitis

Hepatitis is an inflammatory condition of the liver most commonly caused by hepatotropic viruses (A–E), though non-infectious causes such as alcohol and drugs also exist.Hepatitis AHepatitis A virus (HAV) is a non-enveloped RNA virus of the Picornaviridae family. It is primarily transmitted via the fecal-oral route, typically through ingestion of contaminated food or water. After ingestion, HAV enters the bloodstream through the oropharynx or intestinal epithelium and reaches the liver.

Cancer Prevention02:59

Cancer Prevention

Several factors can increase the risk of cancer in an individual. About 50% of cancer cases can be prevented by adopting a healthy lifestyle, regular exercise, eating healthy, and following a modest cancer prevention diet. Epidemiological studies have consistently shown that populations with vegetable and fruit-rich diets have reduced the incidence of cancer. On the other hand, populations who have a diet rich in animal fat, red meat, junk food, or high calories are predisposed to cancer.

Preventive Healthcare Services

Preventive healthcare services keep people healthy via frequent check-ups, screening, and counseling. They primarily aid in disease prevention rather than treating an acute or chronic illness. Preventive treatment also keeps individuals productive and energetic, allowing them to work well into their retirement years. Examples of preventive care services include:

Cancer Vaccines01:30

Cancer Vaccines

Cancer treatment vaccines are a rapidly evolving field that offers a promising approach to immunotherapy. Unlike traditional vaccines that prevent diseases, cancer treatment vaccines are designed to treat existing cancers by stimulating the immune system to recognize and attack cancer cells.
Cancer vaccines come in two categories: preventive (prophylactic) and treatment (active). Preventive vaccines, such as the Human Papillomavirus (HPV) vaccine, protect against viruses that cause certain...

Diseases of the Liver and Gallbladder

Liver and gallbladder diseases are a significant health concern, with prominent conditions including cirrhosis, hepatitis, non-alcoholic fatty liver disease (NAFLD), and gallstones. Jaundice is a common manifestation of liver and biliary disease.
Cirrhosis is characterized by the scarring of hepatic lobules in the liver, which are replaced by fibrous tissue, affecting the liver's normal functioning. NAFLD, on the other hand, is caused by an excessive build-up of fat in the liver, not...
