STOP HCC-GAAD-APAC-Thailand
Sponsor: Mahidol University
Summary
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.

GAAD score
All enrolled participants will undergo standard hepatocellular carcinoma (HCC) surveillance, consisting of blood sampling and abdominal ultrasound performed every 6 months for a total follow-up period of 24 months. Blood samples will be analyzed for serum alpha-fetoprotein (AFP) and protein induced by vitamin K absence or antagonist-II (PIVKA-II) to calculate the GAAD score, a multivariable index incorporating gender, age, AFP, and PIVKA-II. A GAAD score of ≥ 2.57 will trigger a recall procedure, defined as further diagnostic evaluation using multiphasic contrast-enhanced computed tomography (CT) or magnetic resonance imaging (MRI) of the liver. This recall procedure is performed in addition to standard surveillance recall criteria, which include detection of a suspicious hepatic lesion measuring ≥ 1 cm on ultrasound or elevated or rising serum AFP levels (≥ 20 ng/mL).
