Studies show benefits of Cyberknife SBRT for Neurological Disease-Accuray

Accuray announced that studies presented at the 15th European Congress of Neurosurgical Societies reinforce the benefits of the CyberKnife Robotic Radiosurgery System for the treatment of neurological diseases such as meningiomas, acoustic neuromas, trigeminal neuralgia, and spinal tumors. The study included two cohorts of patients with different tumor volumes. In one cohort, 25 patients with a small tumor volume (less than 5 cc) were followed for an average of 60 months (+12 months). In the second cohort, 39 patients with a larger tumor volume (7.5 cc) were followed for an average of 17 months (+10 months). No visual deterioration was observed and tumor control was achieved in all cases. These results support the clinical benefits of CyberKnife treatment for perioptic meningiomas, and were achieved thanks to the ability to fractionate depending on the tumor volume and its proximity to the optic nerve.

Results of a second study indicate that use of the CyberKnife System provides a safe and effective treatment option for people with trigeminal neuralgia. After six months, more than 90 percent of patients showed significant improvement in their symptoms. The system also provided an opportunity to successfully retreat 24 patients who had relapsed within two years from their first treatment.
