Dosimetric evaluation of target coverage as a predictor of local failure following stereotactic body radiation therapy for spinal tumors.

Abstract

Purpose To perform a dosimetric analysis of target coverage and determine parameters predictive for local failure (LF) in patients undergoing spinal stereotactic body radiation therapy (sSBRT).Materials and Methods: Sixty-seven spinal tumors in 59 patients were treated with image-guided linac-based sSBRT from 2008-2012. Median prescription dose was 18Gy (8… (More)
