[Presentation of a grid for computer analysis for compilation of histopathologic lesions in chronic viral hepatitis C. Cooperative study of the METAVIR group].

The METAVIR group, including 10 pathologists with a specialization in liver pathology, has been formed in order to discuss on problems related to chronic viral hepatitis C. Cooperative studies have been planed. At first, observer variation in the assessment of features of chronic viral hepatitis C has been performed. This study has led to the proposal of a coded form for pathological features in liver biopsy of chronic viral hepatitis C. This form will be used to study a large number of biopsies from patients included in clinical trials. In the next future, the prevalence of every of these elementary features will be assessed, as well as correlations between clinical, biological and pathological data.
