Accuray (NSDQ:ARAY) announced today that long-term follow-up data demonstrated pain relief after image-guided robotic radiosurgery treatments with its CyberKnife system.
The data from a study of men and women with trigeminal neuralgia (TN) showed that 72% continued to experience pain relief 10 years after receiving the treatments delivered with the CyberKnife system.
“Robotic Image-Guided Radiosurgery for Trigeminal Neuralgia: Results after 10 Years,” the study abstract, was recognized as “Best Clinical Abstract” at the recent 2022 Radiosurgical Society Meeting in Carlsbad, California, according to a news release.
Sunnyvale, California-based Accuray designed the CyberKnife system to treat diseases in the head and base of the skull, as well as functional disorders, with radiosurgery, but without the use of a fixed frame bolted to the patient’s head.
The company said the system features a linear accelerator (linac) directly mounted on a robot that moves and bends around the patient to deliver non-isocentric, non-coplanar radiation beams from potentially thousands of unique angles. Using advanced imaging and Accuray-exclusive Synchrony real-time target tracking with dynamic delivery technology, Accuray said CyberKnife can track a tumor or lesion and continuously verify its position, automatically correcting and adapting the radiation beam position for the slightest of movements.
Synchrony uses advanced algorithms and AI to account for motion with uninterrupted delivery. With this design, Accuray said the CyberKnife delivers precise and accurate treatments in typically just one to five visits.
“Clinical data continues to confirm the durable benefits that CyberKnife radiosurgery can provide over the long term. The system delivers advanced radiotherapy treatments with sub-millimeter accuracy, which is of critical importance when treating tumors and lesions in the brain while minimizing risk of potential side effects,” Accuray President Suzanne Winter said in the release. “This most recent trigeminal neuralgia study reinforces why medical care teams turn to CyberKnife radiosurgery when precision and accuracy are essential and demonstrates the positive impact this non-invasive treatment option may have on the lives of people living with this severe and challenging-to-treat medical condition.”
