Prognostic factors affecting local control of hepatic tumors treated by Stereotactic Body Radiation Therapy.

Purpose: Robotic Stereotactic Body Radiation Therapy with real-time tumor tracking has shown encouraging results for hepatic tumors with good efficacy and low toxicity. We studied the factors associated with local control of primary or secondary hepatic lesions post-SBRT.

Methods And Materials: Since 2007, 153 stereotactic liver treatments were administered to 120 patients using the CyberKnife® System.
