This summary is about the treatment of primary
liver cancer (cancer that begins in the liver). Treatment of metastatic
liver cancer, which is cancer that begins in other parts of the body and spreads to the liver, is not discussed in this summary. Primary liver cancer can occur in both adults and children. However, treatment for children is different than treatment for adults. See the PDQ summary on Adult Primary Liver Cancer Treatment for more information on the treatment of adults.
Certain diseases and disorders can increase the risk of childhood liver cancer.
Anything that increases your chance of getting a disease is called a risk factor. Having a risk factor does not mean that you will get cancer; not having risk factors doesn’t mean that you will not get cancer. Talk with your child’s doctor if you think your child may be at risk.
Tests that examine the liver and the blood are used to detect (find) and diagnose childhood liver cancer and find out whether the cancer has spread.
The following tests and procedures may be used:
and history: An exam of the body to check general signs of health, including checking for signs of disease, such as lumps or anything else that seems unusual. A history of the patient's health habits and past illnesses and treatments will also be taken.
The amount of hemoglobin
(the protein that carries oxygen) in
the red blood cells.
The portion of the blood sample made up of red blood
Liver function tests: A procedure in which a blood sample is checked to measure the amounts of certain substances released into the blood by the liver. A higher than normal amount of a substance can be a sign of liver damage or cancer.
Blood chemistry studies: A procedure in which a blood sample is checked to measure the amounts of certain substances, such as bilirubin
or lactate dehydrogenase
(LDH), released into the blood by organs and tissues in the body. An unusual (higher or lower than normal) amount of a substance can be a sign of disease.
Hepatitis assay: A procedure in which a blood sample is checked for pieces of the hepatitis virus.
(magnetic resonance imaging) with gadolinium: A procedure that uses a magnet, radio waves, and a computer to make a series of detailed pictures of areas inside the liver. A substance called gadolinium is injected
into a vein. The gadolinium collects around the cancer cells so they show up brighter in the picture. This procedure is also called nuclear magnetic resonance imaging (NMRI).
exam: A procedure in which high-energy sound waves (ultrasound) are bounced off internal tissues or organs and make echoes. The echoes form a picture of body tissues called a sonogram. The picture can be printed to be looked at later. In childhood liver cancer, an ultrasound exam of the abdomen to check the large blood vessels is usually done.
(CAT scan): A procedure that makes a series of detailed pictures of areas inside the body, taken from different angles. The pictures are made by a computer linked to an x-ray
machine. A dye
may be injected
into a vein or swallowed to help the organs or tissues show up more clearly. This procedure is also called computed tomography, computerized tomography, or computerized axial tomography. In childhood liver cancer, a CT scan of the chest and abdomen is usually done.
Abdominalx-ray: An x-ray of the organs in the abdomen. An x-ray is a type of energy beam that can go through the body onto film, making a picture of areas inside the body.
Biopsy: The removal of a sample of cells or tissues so it can be viewed under a microscope
to check for signs of cancer. The sample may be taken during surgery
to remove or view the tumor. A pathologist
looks at the sample under a microscope to find out the type of liver cancer.
The following test may be done on the sample of tissue that is removed:
Immunohistochemistry: A test that uses antibodies
to check for certain antigens
in a sample of tissue. The antibody is usually linked to a radioactive
substance or a dye that causes the tissue to light up under a microscope. This type of test is used to check for a certain genemutation
and to tell the difference between different types of cancer.
Certain factors affect prognosis (chance of recovery) and treatment options.
(chance of recovery) and treatment options for hepatoblastoma depend on the following:
