Childhood Liver Cancer Treatment (PDQ®): Treatment - Patient Information [NCI] - Treatment Option Overview
Factors that affect the type of surgery used include the following:
- The PRETEXT stage (stage of the cancer before surgery).
- The size of the primary tumor.
- Whether there is more than one tumor in the liver.
- Whether the cancer has spread to blood vessels.
- The level of alpha-fetoprotein (AFP) in the blood.
- Whether the tumor can be shrunk by chemotherapy so that it can be removed by surgery.
- Whether a liver transplant is needed.
Chemotherapy is sometimes given before surgery, to shrink the tumor and make it easier to remove. This is called neoadjuvant therapy. Even if the doctor removes all the cancer that can be seen at the time of the surgery, some patients may be given chemotherapy or radiation therapy after surgery to kill any cancer cells that are left. Treatment given after the surgery, to lower the risk that the cancer will come back, is called adjuvant therapy.
Watchful waiting is closely monitoring a patient's condition without giving any treatment until symptoms appear or change.
Chemotherapy is a cancer treatment that uses drugs to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. When chemotherapy is taken by mouth or injected into a vein or muscle, the drugs enter the bloodstream and can reach cancer cells throughout the body (systemic chemotherapy). When chemotherapy is placed directly into the cerebrospinal fluid, an organ, or a body cavity such as the abdomen, the drugs mainly affect cancer cells in those areas (regional chemotherapy). Treatment using more than one anticancer drug is called combination chemotherapy. The way the chemotherapy is given depends on the type and stage of the cancer being treated.
Chemoembolization of the hepatic artery (the main artery that supplies blood to the liver) is a type of regional chemotherapy used to treat childhood liver cancer. The anticancer drug is injected into the hepatic artery through a catheter (thin tube). The drug is mixed with a substance that blocks the artery, cutting off blood flow to the tumor. Most of the anticancer drug is trapped near the tumor and only a small amount of the drug reaches other parts of the body. The blockage may be temporary or permanent, depending on the substance used to block the artery. The tumor is prevented from getting the oxygen and nutrients it needs to grow. The liver continues to receive blood from the hepatic portal vein, which carries blood from the stomach and intestine.
