Title: Local control outcomes using stereotactic body radiation therapy for liver metastases from colorectal cancer

The optimal stereotactic body radiation therapy (SBRT) dose and fractionation schedule for hepatic metastases from colorectal cancer has not yet been determined. Thus, we evaluated the effective dose by reviewing treatment results of 103 lesions. When compared with biological equivalent dose (BED), longer local control was expected if higher doses were used, with optimal BED greater than 132 Gy.
