Which of these hepatitis viruses cause hepatocellular carcinoma of the liver?

Which hepatitis viruses cause hepatocellular carcinoma?

Chronic hepatitis B virus (HBV) infection is a major global cause of hepatocellular carcinoma (HCC). Individuals who are chronic carriers have a greater than 100-fold increased relative risk of developing the tumour. Several mechanisms of HBV-induced HCC have been proposed.

Which hepatitis virus is the most common cause of hepatocellular carcinoma?

In the US, infection with hepatitis C is the more common cause of HCC, while in Asia and developing countries, hepatitis B is more common. People infected with both viruses have a high risk of developing chronic hepatitis, cirrhosis, and liver cancer.

How does hepatitis B cause hepatocellular carcinoma?

HBV likely causes HCC via both indirect (necro-inflammation and regeneration injury) and direct (by integration of its DNA in the host genome) pathways. During recent years it has become evident that HBV viral load >2000 IU/mL is associated with a high risk of malignant transformation.

Is cirrhosis of the liver curable?

Cirrhosis cannot usually be cured, but there are ways to manage the symptoms and any complications, and stop the condition getting worse.

Which hepatitis is not curable?

How to prevent hepatitis B. Hepatitis B is a liver infection caused by a virus (called the hepatitis B virus, or HBV). It can be serious and there’s no cure, but the good news is it’s easy to prevent.

THIS MEANING:  What is a soft tissue tumor?

What cancers are caused by hepatitis B?

Chronic HBV infection can lead to chronic hepatitis, liver cirrhosis, and hepatocellular carcinoma (HCC). HCC is one of the five major cancers in the world population. Hepatitis B virus (HBV) is the most important etiologic agent of liver cancer globally, particularly in high-prevalence areas of liver cancer.

What is the life expectancy of someone with hepatitis B?

The estimated carrier life expectancy is 71.8 years, as compared to 76.2 years among noncarriers (Figure ​ 5). These results are consistent with other estimates, which indicate that 15% to 40% of HBV carriers die of liver complications.

What are the chances of surviving hepatitis B?

The estimated 5-year survival rates were 97% for patients with chronic persistent hepatitis, 86% for those with chronic active hepatitis, and 55% for those with chronic active hepatitis with cirrhosis. The usual cause of death was liver failure and its sequelae.

How can you reverse hepatitis?

Alcoholic hepatitis can be either mild or severe. It is possible to reverse the condition by ceasing to drink alcohol. Severe alcoholic hepatitis can occur without warning, leading to life-threatening complications, such as liver failure.
