  • Ages 20 years and older
  • All sexes
  • No healthy volunteers
  • Adult, Older adult

Study population: Subjects with chronic hepatitis B or C will be eligible for the study. Subjects with other infectious viral diseases or chronic liver disease are excluded for study enrollment. Real-time Tissue Elastography®, serum maker and gastrointestinal endoscopy are performed. If in the hopsital they can perform FibroScan®, FobroScan® also be performed. The time between the Real-time Tissue Elastography®, blood sampling, FiroScan® must not exceed four weeks.

About this study

Official title: Prediction of Incidence of Liver Cancer or PorTal Hypertension in Patients With Viral Hepatitis by Use of Real-time Tissue Elastography

This is a multi-center cohort study in which the Real-time Tissue Elastography® measurements will predict prospectively the incidence of hepatocellular carcinoma, the incidence and severity of gastroesophageal varices ascites and decompensated cirrhosis in hepatitis B or C patients.

Read the detailed description

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.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Cumulative incidence of carcinogenesis of hepatocellular carcinoma

    Cumulative incidence of carcinogenesis of hepatocellular carcinoma defined as the time from registration to diagnosis of hepatoceluler carcinomais

    Measured: every four or six months

Secondary outcomes (4)
  1. Cancer-free survival

    Cancer-free survival is defined as the time from registration to death due to cencer or any cause

    Measured: every four or six months

  2. Overall survival

    Overall survival is defined as the time from registration to death due to any cause

    Measured: one year

  3. The cumulative incidence and severity of gastro-esophageal varices

    It is estimated by gastrointestinal scope for every year

    Measured: one year

  4. The cumulative incidence and severity of decompensated cirrhosis

    Jaundice, ascites, edema and hepatic encephalopathy etc. is evaluated as decompensated cirrhosis.

    Measured: one year

Questions about this trial

What is this clinical trial studying?

An observational study of Chronic Hepatitis B and Chronic Hepatitis C, run by Kindai University at 1 site in Japan.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 2 inclusion and 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 26 May 2011. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Japan. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Norihisa Yada, M.D. (+81-72-366-0221 ext. 3525, yada@med.kindai.ac.jp), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Cumulative incidence of carcinogenesis of hepatocellular carcinoma (time frame: every four or six months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 26 May 2011.
