Gamma Knife Radiosurgery: Karnofsky Performance Scale (N = 152)

2020

Functional status is measured by the Karnofsky Performance Scale, a widely used 11-point scale correlating to percentage values from 100% (no evidence of disease, no symptoms) to 0% (death). In 90% of patients, performance status remained stable or improved after stereotactic radiosurgery. Change in status was defined as a change of ≥ 20 points.
