Precise and Powerful CyberKnife Robot Destroys Inoperable Tumours

Radiosurgery treatment for tumours in brain and other organs revolutionized outcomes for patients

Patients don't need to have a metal halo screwed into their skull when they receive radiation treatment with CyberKnife. That was one of the appealing factors for neurosurgeon Dr. John Sinclair to bring the radiosurgery robot to The Ottawa Hospital.

With previous radiosurgery, a patient with brain tumours had to have their head immobilized during treatment. A metal frame or 'halo' was screwed into their skull and then fastened to the table they'd lie on for treatment. However, a patient does not need to be rigidly immobilized when receiving CyberKnife radiosurgery. The robot uses X-rays and complex precision software to accurately track the tumour, and deliver a high dose of radiation to the precise location of the brain tumour while the patient lies on the table fitted with a custom-made plastic mask.

"CyberKnife has an advantage over regular radiation because it is so much more accurate; precision is less than a millimetre," said Dr. John Sinclair, Director of Cerebrovascular Surgery at The Ottawa Hospital. "You can give very high doses of radiation right to the lesion and get almost no spill over to normal tissue. And as a result, we see much more improved responses to this type of treatment compared to traditional radiation."
