Alpha-Fetoprotein Applications in Hepatocellular Carcinoma Diagnostics
Summary
Alpha-fetoprotein (AFP) has long been established as a cornerstone biomarker in the surveillance and diagnosis of hepatocellular carcinoma (HCC). Originally identified as a foetal serum protein, elevated AFP levels in adults frequently signal hepatic malignancy, especially in cirrhotic or chronically inflamed livers. Its ease of measurement and relative cost-effectiveness have underpinned widespread adoption in clinical protocols, often in combination with imaging modalities such as ultrasound and MRI. Recent advances have focused on refining cut-off thresholds, stratifying patient cohorts by viral status and liver enzyme profiles, and integrating AFP with novel markers to enhance early detection sensitivity. Despite improvements, limitations in specificity remain, with false positives arising from active hepatitis, liver regeneration and non-malignant conditions. Ongoing research aims to tailor AFP-based algorithms according to antiviral treatment status and transaminase levels, and to couple AFP with quantitative imaging tools for a more precise risk assessment. Such integrative approaches promise to elevate diagnostic accuracy, streamline patient triage and ultimately improve outcomes through timely therapeutic intervention.

Alpha-Fetoprotein Applications in Hepatocellular Carcinoma Diagnostics publication trend
The graph below shows the total number of articles in alpha-fetoprotein applications in hepatocellular carcinoma diagnostics across all publications each year (not limited to Nature Index journals).
Technical terms
Alpha-fetoprotein (AFP): A glycoprotein biomarker elevated in the serum of many adult patients with hepatocellular carcinoma.
Hepatocellular carcinoma (HCC): The most common primary malignancy of the liver, often arising in the context of chronic liver disease.
Receiver operating characteristic (ROC) curve: A graphical plot illustrating the diagnostic performance of a test by comparing sensitivity and specificity across thresholds.
Antiviral therapy: Treatment aimed at suppressing viral replication in hepatitis B or C infections, which can modulate tumour marker levels.
Alanine aminotransferase (ALT) and Aspartate aminotransferase (AST): Enzymes released into the bloodstream during liver injury, which can affect biomarker interpretation.
Fibroscan: A non-invasive ultrasound-based technique that measures liver stiffness to assess fibrosis and cancer risk.
