Cholangiocarcinoma
Cholangiocarcinoma is a cancerous (malignant) growth in one of the ducts that carries bile
from the liver to the small intestine.
Alternative Names
Bile duct cancer
Causes, incidence, and risk factors
Cancerous tumors
of the bile ducts are usually slow-growing and do not spread (metastasize) quickly. However, many of these tumors are already advanced by the time they are found.
A cholangiocarcinoma may start anywhere along the bile ducts. These tumors block off the bile ducts.
They affect both men and women. Most patients are older than 65.
Risks for this condition include:
Cholangiocarcinoma is rare. It occurs in approximately 2 out of 100,000 people.
Signs 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:
-
-
-
-
- Endoscopic retrograde cholangiopancreatography (ERCP)
- Magnetic resonance cholangiopancreatography (MRCP)
- Percutaneous transhepatic cholangiogram (PTCA
)
Blood tests that may be done include:
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. However, often the cancer has already spread by the time it is diagnosed.
Chemotherapy or radiation may be given after surgery to decrease the risk of the cancer returning. However, the benefit of this treatment is not certain.
Endoscopic
therapy with stent placement can temporarily relieve blockages in the biliary ducts and relieve jaundice in patients when the tumor cannot be removed. Laser therapy combined with light-activated chemotherapy medications is another treatment option for those with blockages of the bile duct.
Support Groups
You can ease the stress of illness by joining a support group
with members who share common experiences and problems (see cancer - support group
).
Hospice is often a good resource for patients with cholangiocarcinoma that cannot be cured.
Expectations (prognosis)
Completely removing the tumor allows approximately 1 in 5 patients to survive for at least 5 years, with the possibility of a complete cure.
If the tumor cannot be completely removed, a cure is generally not possible. With treatment, about half of these patients live a year, and about half live longer.
Complications
- Infection
- Liver failure
- Spread (metastasis
) of tumor to other organs
Calling your health care provider
Call your health care provider if you have jaundice or other symptoms of cholangiocarcinoma.
