Newest generation of radiosurgical tools now available to patients at Upstate

SYRACUSE, N.Y.— The Upstate Gamma Knife Center at Upstate University Hospital has upgraded its technology to include the newest generation of radiosurgical tools — the Leksell Gamma Knife Perfexion system.

The system offers greater comfort, improved radiation protection, less recovery time and more precise treatment for patients who have metastases or other diseases in the head and neck region. The system gives clinicians the ability to treat multiple lesions in the brain in a single treatment.

“We can treat multiple targets much faster and with unprecedented conformality,” said Gregory Canute, M.D., associate professor of neurosurgery at Upstate Medical University.

The Perfexion gives clinicians unlimited cranial access and has the potential to treat a broader array of conditions than was possible with the original—and highly effective Gamma Knife—which was installed at the Gamma Knife Center in 1998.

The Perfexion is fully automated. Benefits of the system include faster set-up and treatment delivery to one or more tumors in a single session, and the potential to treat select lesions in the paranasal sinuses, orbits and upper cervical spine, paraspinal metastases and laryngeal tumors.

The system directs 192 precise beams of radiation at the target. Strong doses of radiation are released at the exact point where the beams converge, however, before they converge, the individual beams are weak and do not damage the brain tissue.

The Perfexion is especially suitable for treating intracranial lesions such as metastatic brain tumors; arteriovenous malformations; deep-seated intracranial tumors; meningiomas; neoplasms; partially resected tumors; pituitary tumors; trigeminal neuralgia; vascular malformations; skull-based tumors; glomus jugulare; and optic melanoma.

Treatment by the Gamma Knife Perfexion system is performed as an outpatient procedure. Patients may be lightly sedated but are awake throughout the procedure. They go home the same day and often return to work the following day.

More than 100 patients at University Hospital have been treated by the system since it was offered in the Gamma Knife Center in June 2009.
