Cholangiocarcinoma

Definition

Cholangiocarcinoma (CCA) is a rare cancerous (malignant) growth in one of the ducts that carries bile from the liver to the small intestine.

Alternative Names

Bile duct cancer

Causes

Bile duct cancers are slow-growing. They don't spread (metastasize) quickly. The exact cause of CCA isn't known. However, many of these tumors are already quite advanced by the time they are found.

CCA may start anywhere along the bile ducts. These tumors block off the bile ducts.

Both men and women are affected. Most people are older than 65.

People with the following health problems may have a higher chance of developing CCA:

  • Bile duct (choledochal) cysts
  • Chronic biliary and liver inflammation
  • History of infection with parasitic worms, liver flukes
  • Primary sclerosing cholangitis
  • Ulcerative colitis

Symptoms

Symptoms of CCA may include any of the following:

Exams and Tests

Your health care provider will perform a physical exam. Tests will be done to check for a tumor or blockage in the bile duct. These may include:

Blood tests that may be done include:

  • Liver function tests (especially alkaline phosphatase or bilirubin levels)
  • Complete blood count (CBC)

Treatment

The goal is to treat the cancer and the blockage it causes. When possible, surgery to remove the tumor is the treatment of choice and may result in a cure. If the tumor is large, the entire liver may need to be removed and a liver transplant will be needed. Often the cancer has already spread locally or to another area of the body by the time it is diagnosed. As a result, surgery to cure the cancer is not possible.

Chemotherapy or radiation may be given after surgery to decrease the risk of the cancer returning. But the benefit of this treatment is not certain.

Endoscopic therapy with stent placement can temporarily relieve blockages in the biliary ducts. This may also relieve jaundice when the tumor cannot be removed. Laser therapy combined with light-activated chemotherapy medicines is another treatment option for blocked bile duct.

Support Groups

You can ease the stress of illness by joining a support group with members who share common experiences and problems.

Hospice is often a good resource for people with CCA that cannot be cured.

Outlook (Prognosis)

Completely removing the tumor allows some people to survive with the possibility of complete cure.

If the tumor cannot be completely removed, a cure is generally not possible. With treatment, about one half of affected people live a year, and about one half live longer, but rarely beyond 5 years.

Possible Complications

Complications of CCA include:

  • Infection
  • Liver failure
  • Spread (metastasis) of tumor to other organs

When to Contact a Medical Professional

Call your provider if you have jaundice or other symptoms of cholangiocarcinoma.
