Abstract
For many cancers, biomarkers have served as an important tool across the cancer care continuum from risk stratification and early detection to diagnosis and treatment. Alpha fetoprotein (AFP) remains one of the few validated biomarkers for patients with hepatocellular carcinoma (HCC). Although AFP has shown potential for each of these steps, its performance when used alone has often been suboptimal. There continues to be discordant recommendations about AFP's value when combined with ultrasound for surveillance as well as its role in diagnostic algorithms. Conversely, high AFP levels are associated with aggressive tumor biology and survival, so it remains a key factor for selection of liver transplant candidates. There have been immense efforts to identify and validate additional biomarkers for each of these steps in the HCC care continuum. Indeed, biomarker panels have shown promising data for HCC risk stratification and surveillance among patients with cirrhosis, as well as prognostication and detection of minimal residual disease in patients undergoing HCC treatment. Several large prospective studies to evaluate the role of these emerging biomarkers in clinical practice are currently ongoing.
