What should you know about primary cholangiocarcinoma?

The bile ducts carry bile from the liver and gallbladder towards the small intestine. A tumour may develop inside ducts within the liver, near the liver's exit, or farther along the duct system. The tumour's position, size, involvement of nearby vessels and whether it has spread affect the plan.

Assessment can include blood tests, scans and a tissue sample when appropriate. Doctors may check for blockage because reduced bile flow can cause yellowing of the skin or eyes, dark urine, pale stools and itching. These findings can also have non-cancer causes, so they require clinical assessment.

Ask which part of the bile-duct system is involved and what the scans show about nearby structures. A multidisciplinary team may discuss an operation when the tumour can be removed safely. Other plans can include medicines such as chemotherapy or targeted therapy, with the choice guided by tumour features and overall health.

Bile-duct blockage may need treatment to improve drainage before or alongside cancer treatment. Keep a record of symptoms, medicines and test results, and ask who will coordinate your appointments. Learn about [Tumour Removal Surgery](/treatments/surgical-oncology/tumour-removal-surgery/), [Chemotherapy](/treatments/systemic-therapy/chemotherapy/) and [Targeted Therapy](/treatments/systemic-therapy/targeted-therapy/).

Contact your oncology or liver team promptly for worsening yellow skin or eyes, fever or chills, increasing abdominal pain, repeated vomiting, confusion, or inability to keep fluids down. A blocked or infected bile duct can become urgent, particularly when fever occurs with jaundice or pain.

Ask: Where exactly is the tumour? Has it reached nearby vessels or other organs? Is tissue testing needed? What is the purpose and sequence of each treatment? How will jaundice, itching or pain be managed? Who should I call outside clinic hours?
