Recruitment status was: Recruiting
Chronic Hepatitis B
Chronic Hepatitis C
|Study Design:||Time Perspective: Prospective|
|Official Title:||Prediction of Incidence of Liver Cancer or PorTal Hypertension in Patients With Viral Hepatitis by Use of Real-time Tissue Elastography|
- Cumulative incidence of carcinogenesis of hepatocellular carcinoma [ Time Frame: every four or six months ]Cumulative incidence of carcinogenesis of hepatocellular carcinoma defined as the time from registration to diagnosis of hepatoceluler carcinomais
- Cancer-free survival [ Time Frame: every four or six months ]Cancer-free survival is defined as the time from registration to death due to cencer or any cause
- Overall survival [ Time Frame: one year ]Overall survival is defined as the time from registration to death due to any cause
- The cumulative incidence and severity of gastro-esophageal varices [ Time Frame: one year ]It is estimated by gastrointestinal scope for every year
- The cumulative incidence and severity of decompensated cirrhosis [ Time Frame: one year ]Jaundice, ascites, edema and hepatic encephalopathy etc. is evaluated as decompensated cirrhosis.

The aim of this study is to validate the predictive value of Real-time Tissue Elastography® by comparison with serum marker or FibroScan® in chronic hepatitis B or C patients.
Every year and for three years, we performed Real-time Tissue Elastography®, blood sampling, gastrointestinal endoscopy. If in the hospital they can perform FibroScan®, FobroScan® also be performed.
Subjects were also performed ultrasonography (US), computed sonography (CT) or magnetic resonance imaging (MRI) evry four or six months.
The time between the Real-time Tissue Elastography®, blood sampling, gastrointestinal endoscopy and FiroScan® must not exceed four weeks.
