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...
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. The...
Liver Regeneration01:24

Liver Regeneration

The liver is an important organ in vertebrates that plays an essential role in metabolism. It is also responsible for storing and redistributing nutrients such as carbohydrates, fats, and vitamins in the body. Additionally, the liver releases bile salts which are critical for digesting food and eliminating toxic metabolites from the body.
Cells of Liver
The liver comprises four major types of cells— hepatocytes, stellate, Kupffer, and sinusoidal endothelial cells. The hepatocytes are large...
Mutagenicity and Carcinogenicity01:25

Mutagenicity and Carcinogenicity

Mutagenicity and carcinogenicity refer to the ability of drugs to cause genetic defects and induce cancer, respectively. The International Agency for Research on Cancer (IARC) classifies agents into four groups based on their carcinogenic potential. Group 1 agents are known human carcinogens; group 2A agents are probably carcinogenic to humans; group 3 agents lack data to support their role in carcinogenesis; and group 4 includes agents for which data support that they are not likely to be...
Diseases of the Liver and Gallbladder01:26

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...

Summary

Metabolic syndrome is rising, increasing non-alcoholic fatty liver disease (NAFLD) and nonalcoholic steatohepatitis (NASH). NASH-related liver cancer is a growing concern, with a significant annual carcinogenic rate.

Area of Science:

  • Hepatology
  • Oncology
  • Metabolic Diseases

Context:

  • Metabolic syndrome and associated lifestyle diseases are increasing globally.
  • Non-alcoholic fatty liver disease (NAFLD), particularly nonalcoholic steatohepatitis (NASH), is a growing manifestation of metabolic syndrome.
  • While not a direct cause of mortality, NASH progression to liver cirrhosis, liver failure, and liver cancer is a significant health concern.

Purpose:

  • To review the epidemiology of NASH-related liver cancer.
  • To explore gender differences in NASH-related liver cancer.
  • To identify risk factors and pathogenesis of NASH-related liver cancer.

Summary:

  • NAFLD, especially NASH, is increasing due to rising metabolic syndrome.
  • Hepatic fibrosis, a precursor to cirrhosis, elevates cancer risk.

  • NASH-related liver cancer has a notable annual carcinogenic rate of approximately 2.6%.

    • Impact:

    • Highlights the underappreciated risk of liver cancer associated with NASH.
    • Emphasizes the need for increased attention to NASH as a precursor to hepatocellular carcinoma.
    • Provides a foundation for further research into NASH-driven hepatocarcinogenesis.
