Liver Cancer

What causes liver cancer is not fully known — especially when it comes to understanding how certain risk factors spur the transition from normal cells to cancer cells. Doctors do know that several risk factors may increase a person’s chances of developing primary liver cancer. 

The most common risk factors include:

Cirrhosis

Many people who develop liver cancer already had cirrhosis. This disease occurs when damaged liver cells are replaced by scar tissue. It’s most often caused by alcohol abuse or chronic viral hepatitis. 

Chronic viral hepatitis

The most common liver cancer risk factor is long-term infection with hepatitis B or hepatitis C.

Non-alcoholic fatty liver disease

Common in obese people, this condition can cause cirrhosis even in people who drink little or no alcohol.

Gender

Hepatocellular carcinoma is much more common in men than in women.

Ethnicity

In the United States, liver cancer is most common among Asian-Americans and Pacific Islanders. 

It’s unusual, but in some cases a family history of liver cancer or some inherited metabolic diseases may raise the risk. Talk to your doctor about your risk and whether you should consider genetic counseling.

Early detection of liver cancer can increase the likelihood of successful treatment. There’s currently no routine screening exam for liver cancer, but more than 80% of people diagnosed with this cancer also have cirrhosis of the liver, according to the American Cancer Society. Many doctors recommend liver cancer screening using ultrasound imaging and an alpha fetoprotein (AFP) blood test for patients who may have a higher risk of liver cancer. If you’re concerned, talk with your doctor about your risk.

Minimizing your lifestyle risk factors may help with liver cancer prevention. You may be able to lower your risk of developing liver cancer by:

• Preventing or treating chronic viral infections, including hepatitis B and hepatitis C
• Limiting alcoholic beverages
• Maintaining a healthy weight

In addition to a physical exam and family medical history, Scripps physicians use the most advanced liver cancer diagnostic tests.

Ultrasound

Ultrasound uses sound waves to show any growths on the liver, which may be tumors.

Computed tomography (CT) scan

A CT scan uses X-rays to provide detail about the size, shape and location of any growths in the liver and surrounding areas. 

Magnetic resonance imaging (MRI)

An MRI uses radio waves to provide detailed images of the liver and any abnormal growths.

Angiography

Angiography injects a dye into the blood vessels that supply blood to a liver tumor. This makes them visible on an imaging exam, which can help the doctor decide how best to treat the cancer.

A patient’s liver cancer stage is determined by the severity of the disease and if the cancer has spread beyond the liver. Treatment depends the stage, as well as whether a patient has other liver disease (such as cirrhosis) and their general health.

Stage I

Stage I liver cancer is when there’s a single tumor in the liver; the rest of the liver is healthy, and nearby blood vessels are not affected. 

Stage II

Stage II liver cancer is when there are several tumors smaller than 2 inches across, or a tumor has grown into the blood vessels.

Stage III

In stage III liver cancer, at least one tumor is larger than 2 inches across, the tumors have grown into a major vein or the outer covering of the liver stage or another organ, but not into the lymph nodes or distant sites.

Stage IV

Stage IV is when tumors have spread into the lymph nodes or distant organs. 

Resectable, transplantable and unresectable liver cancer

While staging provides information about the severity of liver cancer, it doesn’t indicate how the cancer should be treated. Doctors generally need to know whether the tumor can be removed with surgery (resectable), and may describe the liver cancer as potentially resectable or transplantable, unresectable or advanced.

• Resectable liver cancer is when the tumor is found early and the rest of the liver is healthy. Surgery may be a possibility for removing all of the cancer. 
• Transplantable liver cancer is when the cancer is in its early stages but the rest of the liver is not healthy. A liver transplant may be an option. Since it may be a long time until a liver becomes available, doctors may recommend other treatments to control the cancer.
• Unresectable liver cancer is when tumors haven’t spread, but their size or location means they cannot be safely removed with surgery.
• Advanced liver cancer is when the cancer has spread to the lymph nodes or other parts of the body and cannot be treated with surgery.

No one wants to hear that they have liver cancer. You may feel frightened, overwhelmed, anxious or sad. All of these feelings are perfectly normal. The more you learn about your diagnosis and next steps, the sooner you can begin to make informed decisions about your treatment.

Questions and considerations

Here are some questions you may want to ask your doctor or health insurance provider regarding your liver cancer diagnosis:

• Should I get a second opinion?
• How do I find a specialist?
• What is my cancer treatment plan?
• Will I have to miss work/school?
• What are the side effects of liver cancer treatment?
• How successful is my treatment likely to be?
• What costs will be covered by insurance?
• Which costs will I be responsible for?

Your Scripps cancer care team is here to help you find the answers you need to take an active role in your care. In addition, there are a number of community resources that provide education, information and helpful resources — often at no cost.

The most appropriate liver cancer treatment options depend on several factors, including the type and stage of the cancer and whether the patient has any other liver disease, as well as the patient's age and overall health.

At Scripps, our goal is to completely eliminate your cancer using the most advanced therapies and technologies, including surgery, radiation and drug therapy. Should you need a liver transplant, your physician will recommend short-term treatments designed to address symptoms or manage the disease until you are able to receive a transplant.

Liver resection

Scripps surgeons perform liver resection, or liver cancer surgery, to remove the cancerous portion of the liver, leaving the healthy tissue in place. This procedure can also be performed with robot-assisted surgery though the Scripps Minimally Invasive Robotic Surgery Program.

Liver transplant

Scripps is an international leader in liver transplant procedures. The most common treatment for patients with cirrhosis, liver transplantation removes the diseased liver and replaces it with a healthy liver from a donor. 

Transcatheter chemoembolization (TACE)

Transcatheter chemoembolization is a procedure performed by Scripps interventional radiologists where they implant tiny beads containing chemotherapy directly into tumors, and then use high-energy rays to attack cancer cells.

Stereotactic radiosurgery

This targeted treatment delivers a high dose of radiation to a precise location to kill cancer cells while protecting surrounding healthy tissue and organs from radiation damage. Scripps offers state-of-the-art stereotactic radiosurgery, including Gamma Knife, at our radiation therapy centers in Vista and Encinitas. 

Radiofrequency ablation (RFA)

Scripps interventional radiologists perform radiofrequency ablation, a minimally invasive procedure that uses an electric current to heat and destroy cancer cells.

3-D conformal radiation therapy

With 3-D conformal radiation therapy, our radiation oncologists can visualize a patient’s anatomy in 3-D, enabling them to match the radiation dose to the shape of the tumor while minimizing radiation exposure to surrounding healthy tissues and organs.

Intensity-modulated radiation therapy (IMRT)

Using intensity-modulated radiation therapy (IMRT) — an advanced form of radiation therapy — our radiation oncologists can specify the dose of radiation for the tumor while restricting the dose to surrounding healthy tissues.

Chemotherapy

Most liver cancers are resistant to chemotherapy. However, sorafenib — a class of medications called kinase inhibitors — can slow or stop the progression of liver cancer in patients who are not candidates for surgery.

Some liver cancer treatment plans involve clinical trials. Talk with your physician about whether a clinical trial is right for you. 

For a list of clinical trials that are currently enrolling patients, see our current list of clinical trials.

Your Scripps cancer team will develop a customized treatment plan outlining the treatments and therapies we recommend for your care. Before you begin treatment, you and your physician will review your plan together and discuss any questions or concerns you may have.
