Stereotactic Body Radiation Therapy (SBRT) in Liver Metastasis (COLD 3)
This study is designed to see whether stereotactic body radiation therapy (SBRT) can reduce tumour size, slow progression of the disease, prolong life and improve quality of life. SBRT is concentrated focused radiation therapy delivered very precisely to the liver tumour.
Presently, the treatment for unresectable liver metastases from colorectal cancer is most often chemotherapy or novel targeted therapy. These treatments may improve survival, but not control the metastases permanently; so new treatments are needed to control metastases. It is hoped that knowledge obtained from this study will improve our ability to treat patients with liver tumours that cannot be treated with surgery and other methods, and that SBRT may prove to be a treatment that can lead to long-term and permanent control of liver tumours for some patients.

|Experimental: SBRT for liver mets from colorectal cancer||
Radiation: Stereotactic Body Radiation
Radiation therapy will be delivered on six occasions, over two weeks. Each treatment will take approximately 30 minutes to deliver (up to an hour including all imaging and set-up procedures). You may be asked to swallow 250 cc of oral contrast before each radiation therapy treatment. Pepto Bismol (a liquid that coats the stomach and is used to treat heartburn) and/or water may be combined with the contrast to improve the quality of the stomach's image.
