Abstract
Hepatocellular carcinoma (HCC) is one of the common tumor worldwide and recorded as third most common cause of cancer-related deaths. Invasion of the portal and hepatic veins by HCC is common. But intrabiliary invasion is rare. Radiotherapy (RT) is considered appropriate for unresectable, locally advanced HCC without extrahepatic metastasis. With the conventional RT, it is not possible to deliver a high radiation dose to a treatment volume in a short time and narrow lesion. Recent technological developments in radiation therapy, such as stereotactic body radiation therapy (SBRT), make it possible to deliver a substantial dose of radiation to the tumor and avoid radiosensitive normal liver in the vincinity. We report a patient who were treated by cyberknife therapy for bile duct invasion of progressing HCC despite of treatment.
