Klatskin Tumor (Hilar Cholangiocarcinoma)

Hilar cholangiocarcinoma, also known as Klatskin tumor, is a type of bile duct cancer that occurs at the junction of the right and left hepatic ducts - small tubes that carry bile from the liver. It is the most common form of bile duct cancer, but it is often diagnosed at an advanced stage, making it difficult to treat. Surgical resection is the main curative treatment, but the prognosis is generally poor, with a low 5-year survival rate. Research is ongoing to improve the long-term survival of patients with this type of cancer.
