Liver metastases

Definition

Liver metastases refer to cancer that has spread to the liver from somewhere else in the body.

Liver metastases are not the same as cancer that starts in the liver, which is called hepatocellular carcinoma.

Alternative Names

Metastases to the liver; Metastatic liver cancer; Liver cancer - metastatic; Colorectal cancer - liver metastases; Colon cancer - liver metastases; Esophageal cancer - liver metastases; Lung cancer - liver metastases; Melanoma - liver metastases

Causes

Almost all types of cancer can spread to the liver. Cancers that often spread to the liver include:

The risk for cancer spreading to the liver depends on the location (site) of the original cancer. A liver metastasis may be present when the original (primary) cancer is diagnosed or it may occur months or years after the primary tumor is removed.

Symptoms

In some cases, there are no symptoms. When symptoms occur, they may include:

Exams and Tests

Tests that may be done to diagnose liver metastases include:

Treatment

Treatment depends on:

Types of treatments that may be used are described below.

SURGERY

When the tumor is only in one or a few areas of the liver, it may be removed with surgery.

CHEMOTHERAPY

When the cancer has spread to the liver and other organs, whole-body (systemic) chemotherapy is usually used. The type of chemotherapy used depends on the original type of cancer.

When the cancer has only spread to the liver, systemic chemotherapy may still be used.

Chemoembolization is a type of chemotherapy to one area. A thin tube called a catheter is inserted into an artery in the groin. The catheter is threaded into an artery in the liver. Cancer-killing medicine is sent through the catheter. Then another medicine is sent through the catheter to block blood flow to the part of the liver with the tumor. This "starves" the cancer cells.

OTHER TREATMENTS

Outlook (Prognosis)

How well you do depends on the location of the original cancer and how much it has spread to the liver or anywhere else. In rare cases, surgery to remove the liver tumors leads to a cure. This is usually only possible when there are a limited number of tumors in the liver.

In most cases, cancer that has spread to the liver cannot be cured. People whose cancer has spread to the liver often die of their disease. However, treatments may help shrink tumors, improve life expectancy, and relieve symptoms.

Possible Complications

Complications are often the result of tumors spreading to a large area of the liver.

They can include:

When to Contact a Medical Professional

Anyone who has had a type of cancer that can spread to the liver should be aware of the signs and symptoms listed above, and contact their health care provider if any of these develop.

Prevention

Early detection of some types of cancer may prevent the spread of these cancers to the liver.
