The term 'conformal irradiation' is usually used to describe the delivery of sophisticated high dose external beam irradiation (EBRT) with the aid of 3-D treatment planning and the option of both coplanar and non- coplanar beams. Data will be presented from the University of Michigan which suggest that conformal high dose EBRT (48-72.6 Gy) can be used for intrahepatic cancers, both hepatocellular carcinoma (HCC) and intrahepatic cholangiocarcinoma (IHCC), to potentially increase local control and survival over what would be expected with lower dose EBRT. For purpose of this discussion, the term conformal irradiation will be expanded to include other techniques which conform the high dose irradiation boost volume in close proximity to unresected tumor or positive margins of resection. Data will be presented from series which utilize transcatheter iridium and intraoperative electron irradiation (IOERT) supplements to EBRT ± concomitant chemotherapy. Each method intensifies treatment in an attempt to improve local control and survival.
