Cyberknife stereotactic body radiation therapy for nonresectable tumors of the liver: Preliminary Results

Abstract

Purpose. Stereotactic body radiation therapy (SBRT) has emerged as a treatment option for local tumor control of primary and secondary malignancies of the liver. We report on our updated experience with SBRT in patients with non-resectable tumors of the liver. Methods. Our first 17 consecutive patients (mean age 58.1 years) receiving SBRT for HCC (n=6), IHC (n=3), and LM (n=8) are presented. Mean radiation dose was 34Gy delivered over 1-3 fractions. Results. Treated patients had a mean decrease in maximum pretreatment tumor diameter from 6.9±4.6 cm to 5.0±2.1 cm at three months after treatment (P
