Overview
Bile duct cancer , also known as cholangiocarcinoma , is a rare cancer that forms in the bile ducts, which are tubes that carry bile from the liver to the small intestine. It can occur inside or outside the liver.
Causes
Chronic inflammation of the bile ducts (e.g., primary sclerosing cholangitis) Liver fluke infections Certain genetic conditions or congenital bile duct malformations Exposure to certain chemicals, such as thorotrast (historically used contrast agent)
Symptoms
Jaundice (yellowing of the skin and eyes) Itchy skin Abdominal pain, especially in the upper right side Unexplained weight loss Fever and chills Dark urine and pale stools
Diagnosis
Blood tests including liver function tests and tumor markers (e.g., CA 19-9) Imaging studies: ultrasound, CT scan, MRI, or MRCP Endoscopic procedures with biopsy (ERCP or cholangioscopy) Histopathological examination of tissue samples
Treatment
Surgical removal of the tumor if possible (e.g., hepatectomy or bile duct resection) Radiation therapy for unresectable tumors Chemotherapy to shrink tumors or manage metastasis Palliative care to relieve symptoms and improve quality of life
Prognosis
Prognosis depends on tumor location, stage, and whether surgery is possible Early detection and complete surgical removal improve survival rates
Prevention & Management
Regular monitoring for individuals with chronic bile duct conditions Treat infections promptly, such as liver flukes Maintain a healthy liver with good diet, exercise, and avoiding excessive alcohol
