STOP HCC-GAAD-APAC-Thailand

Hepatocellular carcinoma (HCC) surveillance is frequently underutilized, and currently available biomarkers, such as alpha-fetoprotein (AFP), demonstrate suboptimal diagnostic performance. This prospective study aims to evaluate a simplified multivariate index, the GAAD score-comprising gender, age, alpha-fetoprotein (AFP), and protein induced by vitamin K absence or antagonist-II (PIVKA-II)-for its ability to improve the detection of hepatocellular carcinoma in patients with chronic liver disease. The study hypothesizes that incorporation of the GAAD score into standard HCC surveillance strategies will improve diagnostic performance compared with existing surveillance modalities alone and may provide evidence to support its inclusion in future clinical practice guidelines.
