About

The purpose of this study was to compare efficacy and side effects of two target delineation methods for stereotactic radiotherapy of metastatic spinal tumors.

Full description

The purpose of this study was to compare efficacy and side effects of two target delineation methods for stereotactic radiotherapy of metastatic spinal tumors. This is a bidirectional cohort study planned to enroll approximately 500 patients with metastatic spinal tumors. Patients are divided into two groups according to the target delineation method. Group 1：The target bolume only includes local tumor. Group 2：The target bolume includes local tumor and adjacent vertebral area.
