Stereotactic Radiosurgery for the Treatment of Primary and Metastatic Spinal Sarcomas.

Local treatment of spinal sarcomas has remained a challenge for decades, with poor rates of local control and limited pain relief following conventional radiotherapy. In this series, pain relief was achieved in 82% of treatments at 6 months, with half of patients experiencing pain progression by 12 months. Given minimal toxicity and suboptimal pain control at 12 months, dose escalation beyond 16 Gy is warranted.
