Comparing SingLe- Vs Multi-Fraction Spine STereotActic Radiosurgery in Spinal Metastases

Trial ID or NCT#



recruiting iconRECRUITING


The goal of this study is to determine whether fractionated Stereotactic radiosurgery (SRS) for spine metastases is associated with improved local tumor control compared to single-fraction SRS. Patients will be randomized to treatment with spine SRS using either 22 Gy in 1 fraction or 28 Gy in 2 fractions.
