Radiotherapy

􀂄 Stage IV tumors treated with resection and

radiotherapy, 3yr survival of 10%.(Todoroki et al, World J

surg 15, 1991).

􀂄 Tumor control is rarely achieved by radiotherapy

alone.

􀂄 Brachytherapy via percutaneous transhepatic

approach is used for palliation of obstructive

jaundice due to bile duct obstruction.
