Spine Stereotactic Radiosurgery

Spine Stereotactic Radiosurgery: Survival

In 2017, 108 patients were treated with spine stereotactic radiosurgery, which is mainly used to treat malignant and metastatic tumors of the spine. The 30- and 180-day survival rates for these patients were 98.1% and 97.2%, respectively (for the first 6 months of 2017).

Spine Stereotactic Radiosurgery: Karnofsky Performance Scale (N = 35)


Functional status is measured by the Karnofsky Performance Scale (KPS), a widely used 11-point scale correlating to percentage values from 100% (no evidence of disease, no symptoms) to 0% (death). Performance status, as measured by the Karnofsky Performance Scale (KPS), remained stable or improved in 89% of patients after spine stereotactic radiosurgery. Change in KPS status was defined as a change of ≥ 20 points.
