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.
Patients with liver cancer are treated by a team of specialists who are experts in treating
The patient's treatment will be overseen by a medical oncologist, a doctor who specializes in treating people with cancer. The medical oncologist may refer the patient to other health professionals who have special training in treating patients with liver cancer. These may include the following specialists
Seven types of standard treatment are used:
A partial hepatectomy
to remove the part of the liver
where cancer is found) may be done. A wedge
of tissue, an entire lobe, or a larger part of the liver, along with some of the healthy tissue around it is removed. The remaining liver tissue takes over the functions of the liver and may regrow.
In a liver transplant, the entire liver is removed and replaced with a healthy donated
liver. A liver transplant may be done when the disease is in the liver only and a donated liver can be found. If the patient has to wait for a donated liver, other treatment is given as needed.
removes or destroys tissue. Different types of ablation therapy are used for liver cancer:
- Radiofrequency ablation
: The use of special needles that are inserted directly through the skin or through an incision in the abdomen
to reach the tumor. High-energy radio waves
heat the needles and tumor which kills cancer cells.
- Microwave therapy
: A type of treatment in which the tumor is exposed to high temperatures created by microwaves. This can damage and kill cancer cells or make them more sensitive to the effects of radiation
and certain anticancer drugs.
- Percutaneous ethanol injection
: A cancer treatment in which a small needle is used to inject
(pure alcohol) directly into a tumor
to kill cancer cells. Several treatments may be needed. Usually local anesthesia
is used, but if the patient has many tumors in the liver, general anesthesia
may be used.
: A treatment that uses an instrument to freeze and destroy cancer cells. This type of treatment is also called cryotherapy and cryosurgery. The doctor may use ultrasound
to guide the instrument.
- Electroporation therapy
: A treatment that sends electrical pulses through an electrode
placed in a tumor to kill cancer cells. Electroporation therapy is being studied in clinical trials.
therapy is the use of substances to block or decrease the flow of blood
through the hepatic artery
to the tumor. When the tumor does not get the oxygen
it needs, it will not continue to grow. Embolization therapy is used for patients who cannot have surgery to remove the tumor or ablation therapy and whose tumor has not spread outside the liver.
The liver receives blood from the hepatic portal vein
and the hepatic artery. Blood that comes into the liver from the hepatic portal vein usually goes to the healthy liver tissue. Blood that comes from the hepatic artery usually goes to the tumor. When the hepatic artery is blocked during embolization therapy, the healthy liver tissue continues to receive blood from the hepatic portal vein.
There are two main types of embolization therapy:
- Transarterial embolization
(TAE): A small incision (cut) is made in the inner thigh and a catheter
(thin, flexible tube) is inserted and threaded up into the hepatic artery. Once the catheter is in place, a substance that blocks the hepatic artery and stops blood flow to the tumor is injected.
- Transarterial chemoembolization
(TACE): This procedure is like TAE except an anticancer drug
is also given. The procedure can be done by attaching the anticancer drug to small beads that are injected into the hepatic artery or by injecting the anticancer drug through the catheter into the hepatic artery and then injecting the substance to block the hepatic artery. Most of the anticancer drug is trapped near the tumor and only a small amount of the drug reaches other parts of the body. This type of treatment is also called chemoembolization.
is a treatment that uses drugs or other substances to identify and attack specific cancer cells without harming normal cells. Adult liver cancer may be treated with a targeted therapy drug that stops cells from dividing and prevents the growth of new blood vessels
that tumors need to grow.

is a cancer treatment that uses high-energy x-rays
or other types of radiation
to kill cancer cells or keep them from growing. There are two types of radiation therapy:
- External radiation therapy
uses a machine outside the body to send radiation toward the cancer. Certain ways of giving radiation therapy can help keep radiation from damaging nearby healthy tissue. These types of external radiation therapy include the following:
- Conformal radiation therapy
: Conformal radiation therapy is a type of external radiation therapy that uses a computer to make a 3-dimensional
(3-D) picture of the tumor and shapes the radiation beams to fit the tumor. This allows a high dose
of radiation to reach the tumor and causes less damage to nearby healthy tissue.
- Stereotactic body radiation therapy
: Stereotactic body radiation therapy is a type of external radiation therapy. Special equipment is used to place the patient in the same position for each radiation treatment. Once a day for several days, a radiation machine aims a larger than usual dose of radiation directly at the tumor. By having the patient in the same position for each treatment, there is less damage to nearby healthy tissue. This procedure is also called stereotactic external-beam radiation therapy and stereotaxic radiation therapy.
- Proton beam radiation therapy
: Proton-beam therapy is a type of high-energy, external radiation therapy. A radiation therapy machine aims streams of protons
(tiny, invisible, positively-charged particles) at the cancer cells to kill them. This type of treatment causes less damage to nearby healthy tissue.
- Internal radiation therapy
uses a radioactive
substance sealed in needles, seeds, wires, or catheters that are placed directly into or near the cancer.
The way the radiation therapy is given depends on the type and stage
of the cancer being treated. External radiation therapy is used to treat adult primary liver cancer.
New types of treatment are being tested in clinical trials.
Information about clinical trials is available from the NCI website.
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
listing of clinical trials.
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.
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.
