Insights

Hepatocellular carcinoma (HCC), a major cancer globally, is predominantly found in Asia and Africa. Hepatitis B virus (HBV) infection is the primary driver of HCC worldwide, especially in developing nations.

Area of Science:

  • Hepatology
  • Oncology
  • Infectious Diseases

Background:

  • Hepatocellular carcinoma (HCC) ranks as the fifth most common cancer globally and the third leading cause of cancer-related mortality.
  • Over 80% of HCC cases originate from Asia and Africa, with mainland China accounting for over 50% of these cases.
  • Chronic hepatitis B virus (HBV) infection affects 350-400 million people, serving as the predominant cause of HCC worldwide.

Purpose of the Study:

  • To summarize the global epidemiology of Hepatocellular Carcinoma (HCC).
  • To highlight the significant role of Hepatitis B Virus (HBV) in the global burden of HCC.
  • To note emerging trends in HCC incidence in Western countries.

Main Methods:

  • Literature review and epidemiological data analysis.
  • Synthesis of global cancer statistics.
  • Analysis of HBV infection prevalence and its correlation with HCC.

Main Results:

  • HCC is a leading cause of cancer death, with the highest incidence in Asia and Africa.
  • HBV is responsible for over 50% of liver cancers globally, with up to 89% of HBV-related HCC cases occurring in developing countries.
  • Western countries, including France, Australia, and the United States, are reporting increasing trends in HCC incidence.

Conclusions:

  • Hepatocellular carcinoma (HCC) represents a significant global health challenge, disproportionately affecting Asian and African populations.
  • Hepatitis B virus (HBV) is the primary etiological factor for HCC worldwide, particularly in resource-limited settings.
  • The rising incidence of HCC in Western nations warrants further investigation and public health attention.

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. The...

Viral Hepatitis I: Introduction

Viral hepatitis is an inflammatory condition of the liver caused by infection with hepatotropic viruses, most commonly hepatitis A, B, C, D, and E. Despite variations in structure and transmission, all viruses mentioned infect hepatocytes and provoke immune responses that can hinder liver function. Additionally, some non-hepatotropic viruses can also lead to hepatic inflammation.Hepatitis A VirusHepatitis A virus (HAV) is transmitted through the fecal–oral route, typically by ingestion of food...
Cirrhosis I: Introduction01:23

Cirrhosis I: Introduction

Cirrhosis is a chronic, irreversible liver disease characterized by the widespread replacement of healthy liver tissue with fibrotic scar tissue and the formation of regenerative nodules.Etiology of cirrhosisCirrhosis results from sustained liver injury that triggers progressive fibrosis and structural remodeling. The underlying causes are diverse, encompassing common and less frequent clinical conditions. Regardless of the origin, all causes lead to chronic inflammation, hepatocyte loss, and...
Cirrhosis II: Pathophysiology01:24

Cirrhosis II: Pathophysiology

Cirrhosis is a progressive chronic liver injury caused by prolonged inflammation, excessive fibrotic remodeling, and impaired regeneration. Over time, repeated hepatic insults disrupt the liver’s architecture and function, leading to reduced blood flow, impaired bile drainage, and diminished metabolic capacity.Pathophysiology of cirrhosisCirrhosis arises from three main responses to chronic liver damage: inflammation, immune activation, and hepatocyte death. These processes lead to structural...

Chronic Pancreatitis II: Pathophysiology

Chronic pancreatitis is a progressive and irreversible inflammation of the pancreas, most often caused by long-term alcohol abuse, but it can also be related to ductal obstruction, smoking, or genetic factors.Chronic pancreatitis occurs when the pancreas is repeatedly exposed to harmful agents like alcohol, smoking, ductal obstruction, or genetic predisposition. These factors lead to the release of toxic metabolites and inflammatory cytokines, sustaining chronic inflammation in the pancreatic...

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 related to...
