hepatoma

 [hep″ah-to´mah]
1. a tumor of the liver.

hepatocellular carcinoma (HCC),

[MIM*114550]
Malignant tumor of the liver that develops in the setting of chronic liver disease or cirrhosis. Hepatocellular carcinoma is derived from hepatocytes that are transformed into adenocarcinoma. Up to 60% of patients with HCC have elevated serum alpha fetoprotein levels. Tumor has a poor long-term prognosis unless treated surgically by resection or liver transplantation. Noninvasive imaging (e.g., MRI or CT scan) may distinguish hepatomas from other benign tumors such as hemangiomas.

hepatoma

[hep′ətō′mə] pl. hepatomas, hepatomata
Etymology: Gk, hēpar + oma, tumor
a primary malignant tumor of the liver, which is relatively rare in the United States, characterized by hepatomegaly, pain, hypoglycemia, weight loss, anorexia, and ascites, as well as elevated serum alpha-fetoprotein levels, portal hypertension, and jaundice in the plasma. It occurs most commonly in the sixth decade, and its incidence is higher in African-Americans than in Caucasians. It occurs most frequently in association with hepatitis or cirrhosis of the liver and in those parts of the world where the mycotoxin aflatoxin is found. It is treated with surgical resection when isolated to one lobe of the liver. The prognosis is poor. Chemotherapy and liver transplantation are used in some centers.

hepatoma

A primary cancer of the liver (hepatocellular carcinoma). Primary liver cancer is rare in the Western world while secondary cancer is very common. Hepatomas are common in areas in which exposure to HEPATITIS B and AFLATOXINS occur frequently. In these areas, males with CIRRHOSIS are especially prone. There are high blood levels of ALPHAFETOPROTEIN. Surgery is sometimes feasible but the outlook is poor.

hepatoma

any tumor of the liver, especially hepatocellular carcinoma (malignant hepatoma).
