INTRODUCTION: An overview of the effectiveness of radiosurgery in @entity1 diagnosed with @entity4254 with an analysis of potential predictors of good outcome. METHODS: All @entity1 treated with linear accelerator radiosurgery between 2004 and 2011 were analysed. A dose of 60Gy dose was administered 1 to 2mm from the root entry zone with a maximum isodose of 20% delivered to the brainstem. Clinical results for @entity158 control and any side effects were analysed at 12 and 36 months (BNI score). RESULTS: The study included 71 @entity1 (mean follow-up 50.5 months). @entity158 improvement at 12 months was observed in 68.11% of the total (28.98% with BNI score i-ii; 39.12% with BNI score iii) and at 36 months in 58.21% (23.88% BNI score i-ii; 34.32% BNI score iii). Average recovery time was 3.69 months and the relapse rate was 44.68%. @entity1 with typical @entity158 displayed statistically significant differences in improvement rates at 12 and at 36 months (P<047 and P<.002). Onset of improvement was analysed using Kaplan-Meyer plots. Statistically significant differences were observed between @entity1 with typical and atypical @entity158 at 36 months (P<.012) in Kaplan-Meyer plots. Side effects were recorded in 15 @entity1 (20.89%), including 9 cases of facial @entity1183 (13.43%); only 2 cases were clinically relevant (2.98%). CONCLUSION: According to our results, radiosurgery is an effective treatment for @entity4254 , with few side effects. Typical @entity158 seems to be a good predictor of @entity158 relief.
