Hepatocellular carcinoma involves a malignant tumor of the liver.
Alternative Names
Primary liver cell carcinoma; Tumor - liver; Liver cancer; Cancer - liver
Causes, incidence, and risk factors
Hepatocellular carcinoma accounts for 80% to 90% of all liver cancers. It occurs more often in men than women and occurs mostly in people 50 to 60 years old. The disease is more common in parts of Africa and Asia than in North and South America and Europe. The cause of liver cancer is unknown, but contributing factors include chronic liver disease , viral hepatitis (especially hepatitis B and C), hemochromatosis , known hepatic (liver) carcinogens, and toxins (mycotoxins) found in foods in parts of Africa and Asia. The incidence is about 4 in 10,000 people.
Signs and tests
Physical examination shows an enlarged, tender liver. A liver biopsy shows hepatocellular carcinoma.
Serum alpha fetoprotein is elevated. There may be a mass shown on abdominal CT scan .
A liver scan may indicate an abnormality.
Liver enzymes ( liver function tests ) are elevated.
Hepatocellular carcinoma may also alter the following test results:
Porphyrins; urinePBGLeucine aminopeptidase - serumLeucine aminopeptidase - urineGamma-glutamyl transpeptidaseGall bladder radionuclide scanDelta-ALABilirubin; urineASTALTAlpha-1 antitrypsin5'-N'Tase
Treatment
Aggressive surgery or liver transplantation may be successful in treating small or slow-growing tumors if they are diagnosed early. Chemotherapy and radiation treatments are not usually effective but may be used to shrink large tumors so that surgery has a greater chance of success.
Support groups
The stress of illness can often be helped by joining a support group where members share common experiences and problems. See liver disease - support group and cancer - support group .
Expectations (prognosis)
The usual outcome is poor, because only 10% to 20% of hepatocellular carcinomas can be removed completely using surgery. If the cancer cannot be completely removed, the disease is usually fatal within 3 to 6 months.
Complications
Gastrointestinal bleeding Liver failure Spread ( metastasis ) of the carcinoma
Calling your health care provider
Call your health care provider if persistent abdominal pain develops, particularly if there has been a history of any liver disease .
Prevention
Control of known hepatic carcinogens may have a preventive effect. Prevention and treatment of viral hepatitis may be beneficial in reducing risk.
