Adult primary liver cancer is a disease in which malignant (cancer) cells form in the tissues of the liver.
The liver is one of the largest organs in the body. It has four lobes and fills the upper right side of the abdomen inside the rib cage. The liver has many important functions, including:
This summary refers to 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. Treatment for children, however, is different than treatment for adults. (Refer to the PDQ summary on Childhood Liver Cancer Treatment for more information.)
Having hepatitis or cirrhosis can affect the risk of developing adult primary 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. People who think they may be at risk should discuss this with their doctor. The following are possible risk factors for adult primary liver cancer:
Possible signs of adult primary liver cancer include a lump or pain on the right side.
These symptoms may be caused by swelling of the liver. These and other symptoms may be caused by adult primary liver cancer or by other conditions. A doctor should be consulted if any of the following problems occur:
Tests that examine the liver and the blood are used to detect (find) and diagnose adult primary liver cancer.
The following tests and procedures may be used:
Certain factors affect prognosis (chance of recovery) and treatment options.
The prognosis (chance of recovery) and treatment options depend on the following:
Prognosis is also affected by alpha-fetoprotein (AFP) levels.
After adult primary liver cancer has been diagnosed, tests are done to find out if cancer cells have spread within the liver or to other parts of the body.
The process used to find out if cancer has spread within the liver or to other parts of the body is called staging. The information gathered from the staging process determines the stage of the disease. It is important to know the stage in order to plan treatment. The following tests and procedures may be used in the staging process:
There are three ways that cancer spreads in the body.
The three ways that cancer spreads in the body are:
When cancer cells break away from the primary (original) tumor and travel through the lymph or blood to other places in the body, another (secondary) tumor may form. This process is called metastasis. The secondary (metastatic) tumor is the same type of cancer as the primary tumor. For example, if breast cancer spreads to the bones, the cancer cells in the bones are actually breast cancer cells. The disease is metastatic breast cancer, not bone cancer.
The following stages are used for adult primary liver cancer:
Stage I
In stage I, there is one tumor and it has not spread to nearby blood vessels.

Pea, peanut, walnut, and lime show tumor sizes.
Stage II
In stage II, one of the following is found:
Stage III
Stage III is divided into Stage IIIA, IIIB, and IIIC.
Stage IV
In stage IV, cancer has spread beyond the liver to other places in the body, such as the bones or lungs. The tumors may be of any size and may also have spread to nearby blood vessels and/or lymph nodes.
For adult primary liver cancer, stages are also grouped according to how the cancer may be treated. There are 3 treatment groups:
Localized resectable
The cancer is found in the liver only, has not spread, and can be completely removed by surgery.
Localized and locally advanced unresectable
The cancer is found in the liver only and has not spread, but cannot be completely removed by surgery.
Advanced
Cancer has spread throughout the liver or has spread to other parts of the body, such as the lungs and bone.
Recurrent adult primary liver cancer is cancer that has recurred (come back) after it has been treated. The cancer may come back in the liver or in other parts of the body.
There are different types of treatment for patients with adult primary liver cancer.
Different types of treatments are available for patients with adult primary liver cancer. Some treatments are standard (the currently used treatment), and some are being tested in clinical trials. A treatment clinical trial is a research study meant to help improve current treatments or obtain information on new treatments for patients with cancer. When clinical trials show that a new treatment is better than the standard treatment, the new treatment may become the standard treatment. Patients may want to think about taking part in a clinical trial. Some clinical trials are open only to patients who have not started treatment.
Four types of standard treatment are used:
Surgery
The following types of surgery may be used to treat liver cancer:
Radiation therapy
Radiation therapy is a cancer treatment that uses high-energy x-rays or other types of radiation to kill cancer cells or keep them from growing. Radiation therapy is given in different ways:
The way the radiation therapy is given depends on the type and stage of the cancer being treated.
Chemotherapy
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 spinal column, an organ, or a body cavity such as the abdomen, the drugs mainly affect cancer cells in those areas (regional chemotherapy).
Regional chemotherapy is usually used to treat liver cancer. A small pump containing anticancer drugs may be placed in the body. The pump puts the drugs directly into the blood vessels that go to the tumor.
Another type of regional chemotherapy is chemoembolization of the hepatic artery. 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.
The way the chemotherapy is given depends on the type and stage of the cancer being treated.
Percutaneous ethanol injection
Percutaneous ethanol injection is a cancer treatment in which a small needle is used to inject ethanol (alcohol) directly into a tumor to kill cancer cells. The procedure may be done once or twice a week. Usually local anesthesia is used, but if the patient has many tumors in the liver, general anesthesia may be needed.
New types of treatment are being tested in clinical trials.
This summary section describes treatments that are being studied in clinical trials. It may not mention every new treatment being studied. Information about clinical trials is available from the NCI Web site (see also: clinical trials at the Masonic Cancer Center) .
Hyperthermia therapy
Hyperthermia therapy is a type of treatment in which body tissue is exposed to high temperatures to damage and kill cancer cells or to make cancer cells more sensitive to the effects of radiation and certain anticancer drugs. Because some cancer cells are more sensitive to heat than normal cells are, the cancer cells die and the tumor shrinks.
Biologic therapy
Biologic therapy is a treatment that uses the patient's immune system to fight cancer. Substances made by the body or made in a laboratory are used to boost, direct, or restore the body's natural defenses against cancer. This type of cancer treatment is also called biotherapy or immunotherapy.
Patients may want to think about taking part in a clinical trial.
For some patients, taking part in a clinical trial may be the best treatment choice. Clinical trials are part of the cancer research process. Clinical trials are done to find out if new cancer treatments are safe and effective or better than the standard treatment.
Many of today's standard treatments for cancer are based on earlier clinical trials. Patients who take part in a clinical trial may receive the standard treatment or be among the first to receive a new treatment.
Patients who take part in clinical trials also help improve the way cancer will be treated in the future. Even when clinical trials do not lead to effective new treatments, they often answer important questions and help move research forward.
Patients can enter clinical trials before, during, or after starting their cancer treatment.
Some clinical trials only include patients who have not yet received treatment. Other trials test treatments for patients whose cancer has not gotten better. There are also clinical trials that test new ways to stop cancer from recurring (coming back) or reduce the side effects of cancer treatment.
Clinical trials are taking place in many parts of the country. See the Treatment Options section that follows for links to current treatment clinical trials. These have been retrieved from NCI's clinical trials database.
Follow-up tests may be needed.
Some of the tests that were done to diagnose the cancer or to find out the stage of the cancer may be repeated. Some tests will be repeated in order to see how well the treatment is working. Decisions about whether to continue, change, or stop treatment may be based on the results of these tests. This is sometimes called re-staging.
Some of the tests will continue to be done from time to time after treatment has ended. The results of these tests can show if your condition has changed or if the cancer has recurred (come back). These tests are sometimes called follow-up tests or check-ups.
A link to a list of current clinical trials is included for each treatment section. For some types or stages of cancer, there may not be any trials listed. Check with your doctor for clinical trials that are not listed here but may be right for you.
