Elevation of alpha-fetoprotein levels is a characteristic finding in which tumor?
Alpha-fetoprotein (AFP) is commonly elevated in patients with hepatocellular carcinoma (hepatoma), particularly in those with underlying cirrhosis or chronic hepatitis B/C. AFP is not typically elevated in adenomas, cholangiocarcinoma, or FNH.
According to Rumack's Diagnostic Ultrasound:
''Serum AFP levels are elevated in 50--70% of patients with hepatocellular carcinoma.''
