Stereotactic Radiosurgery: Gamma Knife

The 30- and 180-day survival rates (for the first 6 months of 2017) remained robust for Gamma Knife radiosurgery treatment, independent of tumor type.

Gamma Knife Radiosurgery: Survival by Tumor Type – Meningioma
Gamma Knife Radiosurgery: Survival by Tumor Type – Schwannoma
Gamma Knife Radiosurgery: Survival by Tumor Type – Pituitary
Gamma Knife Radiosurgery: Survival by Tumor Type – Metastasis
Gamma Knife Radiosurgery: Karnofsky Performance Scale (N = 230)

2017

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 92% of patients after Gamma Knife radiosurgery. Change in KPS status was defined as a change of ≥ 20 points.
