Extracranialoligometastasis is most common in lung, liver and bone. The standard treatment is systemic chemotherapy but the value of chemotherapy is limited. So, we can suppose the beneficial effects from the addition of local therapy such as metastasectomy, cooling or heating method of tumor and radiotherapy. Stereotactic body radiotherapy is an alternative approach for surgically unresectable lesions because of proximity to blood vessels or other critical structures and multilobar involvement and for the medically inoperable patients or patients who do not require surgery. Extrahepatic metastasis from hepatocellular carcinoma has no general agreement on the optimal treatment strategy. Helical tomotherapy, a new type of dynamic radiotherapy, is an intensity modulated radiotherapy system equipped with megavoltage computed tomography image guidance. We can precisely deliver high dose of radiation to the tumor with maximal sparing of around normal tissue and simultaneously irradiate the multiple tumor using tomotherapy. We introduce the clinical experience of tomotherapy in oligometastasis and metastatic hepatocellular carcinoma for the last several years.
