Summary

The goal of this prospective observational study is to test the impact of addition of the GAAD score to imaging in patients with chronic liver disease eligible for HCC surveillance. The main questions it aims to answer are: * Diagnostic accuracy of the GAAD score (cut-off 2.57 (3)) for detection of HCC (overall and by BCLC stage), expressed using sensitivity, specificity, negative predictive value and positive predictive value. * Change in GAAD score over time, and proportion of patients with a GAAD score above the cut-off over time in relation to potential confounding factors (e.g. age, bilirubin levels, presence of HCC). 1000 participants with chronic liver disease eligible for HCC surveillance will be enrolled. Data will be collected for 3 consecutive years after enrollment. As per clinical practice, patients will undergo standard bi-annual HCC surveillance comprising liver imaging with ultrasound (or CT or MRI based on previous investigations) and GAAD score assessment based on blood samples.

Interventions

Type	Name	Description
DIAGNOSTIC_TEST	GAAD score	In order to calculate the GAAD score an in-vitro diagnostic is used. The Elecsys GAAD assay by Roche Diagnostics is used to assess the GAAD score using on blood samples collected from patients during regular outpatient clinic visits. The Elecsys GAAD test combines the results of the Elecsys PIVKA-II and Elecsys AFP assays with gender and age (the GAAD score is calculated with PIVKA-II, AFP, gender and age).
