Liver Cancer

The liver, one of the largest organs of the body, has many important functions that keep a person healthy. It removes harmful material from the blood, produces enzymes and bile that help digest food and converts food into substances needed for life and growth.

Cancer of the liver, which may be primary or secondary cancer, involves an uncontrolled growth of cells. Primary cancer arises within the liver and in its early stages exists only in the liver. Secondary liver cancer, also called metastatic cancer, originates in another organ, such as the colon, stomach, pancreas or breast and then spreads to the liver. Because secondary cancer is present in at least two organs, the treatment possibilities are more limited than for primary liver cancer.

Primary liver cancer can affect anyone, but it occurs most frequently in people with advanced liver disease. In the United States, the risk is greatest for those with longstanding hepatitis B, advanced hepatitis C and cirrhosis. Because hepatitis viruses are so widespread, liver cancer is the second most common cause of cancer death worldwide.

Certain inherited conditions also predispose a person to liver cancer, including tyrosinemia in children, a rare disorder in which the body can't effectively break down the amino acid tyrosine, and untreated hemochromatosis, a disorder that causes the body to absorb and store too much iron, in adults. Common to all these conditions is chronic liver inflammation and injury.

One of the objectives of current research at UCSF is to determine why liver inflammation and injury lead to liver cancer.
