... months after GKRS, 25.0% at 6 months, and 7.1% at 12 months. The mean and median progression-free survival (PFS) periods were 8.6 (95% CI, 6.3–11.0) and 4 (95% CI, 3.5–4.5) (range, 1–60) months, respectively. The overall survival (OS) after GKRS was 3–62 months, with a mean of 16.7 (95% CI, 14.6–18.9...

... scoring system for the prediction of survival time. Methods: We retrospectively analyzed data for 311 patients treated with Gamma Knife radiosurgery at a single institute. The mean age at time of treatment was 60 years (range 23–86 years), and the median Karnofsky performance status (KPS) score was 90...

... survival duration was 21.1 months for all patients. Median tumor volume was 14.3 cm 3 (range, 10.0–58.3 cm 3 ). The local control rate was 77.0% and the progression-free survival rate was 73.6% at the last follow-up. There were no significant between-group differences in terms of local control rate ( p...

... rate of complication ( p = 0.056). Median progression-free survival (PFS) and overall survival (OS) for recurrent GBM were 7.4 and 11.6 months, respectively. As a frontline treatment for newly diagnosed GBM, median PFS and OS were 5.9 and 11.4 months, respectively. For metastases, median PFS...

... neurosurgical craniotomy (NS; 130 patients), whole-brain radiotherapy (WBRT; 120 patients). Linac XKnife radiosurgery (RS; 130 patients) and Linac XKnife radiosurgery plus WBRT (RT; 83 cases). Survival was measured from the time of treatment and was analyzed by the Kaplan-Meier product-limit method...
