Evaluation and Medico-Economic Study of FIBROSCAN in Patients With Viral Hepatitis (FIBROSTIC)

February 11, 2009 updated by: Assistance Publique - Hôpitaux de Paris

Evaluation and Medico Economic Study of FIBROSCAN in Patients With Viral Hepatitis

A new approach to the evaluation of liver fibrosis has been proposed using PULSOMETRY. The objective is to evaluate the diagnostic performances of the FIBROSCAN technique, together with non-invasive techniques, and to determine how it is able to predict the histological fibrosis score, defined by the METAVIR score. This transversal study aims to compare the evaluation of hepatic fibrosis obtained by FIBROSCAN and histology (METAVIR score) in 2550 consecutive patients taken in charge for a liver biopsy. The results of the study will compare the respective performances of these techniques in the prediction of the METAVIR score, and help in the recommendation of the care of patients with viral hepatitis B and C; these methods will undergo a medico-economic study.

Detailed Description

The gold standard for the evaluation of fibrosis is considered as the METAVIR score by the clinicians. The results of this score are currently used for clinical decisions and description of the evolution of the disease. FIBROSCAN would be interesting in avoiding liver biopsies, if it was able to predict accurately the METAVIR score obtained if a liver biopsy was performed. The data available on diagnostic performances of FIBROSCAN are incomplete, the number of patients studied and the methods selection (blindness of the results of other techniques) are not precise in some of them. The main objective of this study is therefore to evaluate the performance of FIBROSCAN in the prediction of METAVIR score > 2 (vs F0 or F1). An ancillary study will try to evaluate the diagnostic performance of FIBROSCAN in the global prediction of METAVIR score. A statistical method will be tested using the reference method as an ordinal polytropic variable. Half of the sample (1250 patients) will be used to determine the best THERSHOLD of FIBROSCAN in each of the clinical subgroups of patients, in order to obtain a high sensibility. The second half will be used as the validation sample, and the threshold will be used to estimate the sensibility, specificity and other diagnostic parameters of the FIBROSCAN. The secondary objectives are:

  1. to evaluate the performance of FIBROSCAN in the prediction of METAVIR score in adjacent classes of fibrosis (F0-F1, F1-F2, F2-F3, F3-F4), and
  2. to study the association between elastometry and fibrosis surface obtained by morphometry (considered as the best evaluation of global liver fibrosis).

This technique will be applied to a restricted number of biopsies (consecutive biopsies > 2cm).
