Cholangiocarcinoma (CCA) is a rare cancerous (malignant) growth in one of the ducts that carries bile from the liver to the small intestine.
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:
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:
- Abdominal CT scan
- Abdominal ultrasound
- Procedure that uses a viewing scope to look at the bile ducts (ERCP), during which tissue may be taken and looked at under a microscope
Blood tests that may be done include:
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. 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.
In select cases, a liver transplant can be tried.
Endoscopic therapy with stent placement can temporarily relieve blockages in the biliary ducts. This may also relieve jaundice when the tumor cannot be removed.
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.
Hospice is often a good resource for people with CCA that cannot be cured.
Complications of CCA include:
- 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.
