SBRT has potential role in HCC, liver mets, cholangiocarcinoma, pancreas, Klaskin tumour, GIST. The initial results are impressive with low toxicity, high response rate Short course, high dose radiation therapy will improve local control and may improve survival function. The data presented in this presented is emerging data.
