Stereotactic Body Radiation Therapy for Liver Metastases 30

The concept and technique of stereotactic body radiation therapy (SBRT) is presented. This focally tumor-ablative radiation approach is delivered in a few fractions of high radiation doses to a limited volume of metastatic disease to the liver. Indications include one to five metastatic lesions with maximum diameters up to 5 cm. While clinical experience is limited with few larger case series, preliminary outcomes with respect to tumor control and normal liver sparing are encouraging. This new treatment modality offers patients an alternate noninvasive treatment modality promising high local tumor control rates.
