Summary

This prospective and multicenter study is to determine the diagnostic performance (accuracy, specificity and sensitivity) of transient elastography (FibroTouch) for liver fibrosis assessment in chronic hepatitis B (CHB) patients using ROC analysis, and liver biopsy as the reference. Actual 517 patients will be enrolled to guarantee 500 final statistical cases; and ≥100 cases are required for fibrosis stage S0/1, S2, S3 and S4 (compensatory stage of cirrhosis), respectively. For each stage, the case is assigned as equally as possible.

Detailed description

The liver diseases frequently occur in China. For various reasons, the chronic liver diseases are not controlled in time, and then develop gradually into liver fibrosis and cirrhosis. Without effective treatment, the advanced liver cirrhosis seriously influences the quality of patients' life, and places an intolerable burden on family and society. At present, the scholars generally thought that the liver fibrosis at early stages is reversible. Therefore, if the liver fibrosis in patients with chronic liver diseases can be accurately evaluated at early stages and be treated in time, so we can stop the progress of diseases and reduce the occurrence of liver cirrhosis and liver cancer. For many years, liver biopsy is still as "golden standard" for diagnosis of liver inflammation and fibrosis. However, with its invasiveness, potential risks and some complications, liver biopsy is limited in clinical application due to the poor acceptability and repeatability. In recent years, the liver fibrosis cannot directly and accurately diagnose via the various diagnostic models using serological biomarkers (e.g. FIBROTEST and APRI) and medical imaging technologies (e.g. ultrasonic B, CT and MRI). Transient elastography is a new technology in the field of ultrasonic imaging. Liver stiffness measurement (LSM) is based on the relationship between the speed of spread of acoustic wave in tissues and stiffness of the tissues. It utilizes specific probes to send out controlled low-frequency shear waves, the waves signals transmit through liver tissues, a high-frequency signals will track the transmitting process of shear wave in the liver and the value of liver stiffness (kPa) is quickly calculated with reference to a built-in liver histological model, which provides a quantitative standard for diagnosis of liver fibrosis of chronic liver disease. The bigger LSM value means the faster transmission of shear wave, and the harder of determined liver tissue. As stated in the "12th Five-year Plan for Medical Device Technological Industry" (the Ministry of Science and Technology), China will greatly support the research and development of new medical devices and promote the application of Chinese transient elastography system, FibroTouch, which was R\&D by Tsing-Hua University independently with new algorithm. FibroTouch can rapidly determine the LSM in a non-invasive way and provide useful information for liver fibrosis and steatosis staging. Due to FibroTouch is a new transient elastography system in marketing, there is no too much studies on the correlation between FibroTouch and liver biopsy in diagnosis of liver fibrosis and cirrhosis. The goal of this prospective and multicenter study is to determine the diagnostic performance (accuracy, specificity and sensitivity) of FibroTouch for liver fibrosis assessment in chronic hepatitis B (CHB) patients using ROC analysis, and liver biopsy as the reference. Actual 517 patients will be enrolled to guarantee 500 final statistical cases; and ≥100 cases are required for fibrosis stage S0/1, S2, S3 and S4 (compensatory stage of cirrhosis), respectively. For each stage, the case is assigned as equally as possible.

Conditions

• Liver Fibrosis
• Cirrhosis
• Chronic Hepatitis B

Interventions

Type	Name	Description
DEVICE	FibroTouch Examination	Liver stiffness measurements are performed using FibroTouch and the procedure is non-invasive and painless.
DEVICE	FibroScan Examination	Liver stiffness measurements are performed using another transient elastography, FibroScan, and the procedure is non-invasive and painless.
DEVICE	Ultrasonic B Examination	The ultrasonic B examination is made at an empty stomach for ≥8h. The inner diameter of liver, spleen, gallbladder, portal vein and splenoportal vein is measured through the ordinary two-dimensional ultrasonic examination. The echo data of liver surface/edge/parenchyma and gallbladder wall is scored to evaluate the severity of fibrosis.
