French hospital treats 10,000th patient with Gamma Knife

 On Tuesday, November 30, 2010, neurosurgeons at University Hospital La Timone (Marseilles, France) used their Leksell Gamma Knife® Perfexion™ system to deliver radiosurgery to the center’s 10,000th patient, a 40-year-old woman. The treatment comes in the 18th year of the hospital’s Gamma Knife® program, which has employed four different versions of Leksell Gamma Knife , considered the gold standard for brain radiosurgery.

Gamma Knife radiosurgery is a gentler alternative to traditional brain surgery for illnesses such as metastatic disease, which is cancer that has travelled to the brain from elsewhere in the body. With pinpoint accuracy, the system delivers up to thousands of low-intensity radiation beams to one or more targets in a single session. Perfexion provides even greater speed and ease of use than previous models.

"To have offered the benefits of Gamma Knife radiosurgery to so many patients after just 18 years is quite gratifying and speaks to the enduring value and effectiveness of this continually evolving technology," says La Timone neurosurgeon and Gamma Knife program director, Jean Régis, M.D.
At an industrious pace of five to ten Gamma Knife surgeries per day in recent years, Hospital La Timone is on course to make 2010 its busiest Gamma Knife year ever, with patients treated predicted to exceed 900.
Since acquiring its Perfexion system in 2006, Hospital La Timone has harnessed this system’s faster workflow and larger treatable volume to improve and expand its radiosurgery applications.

"We clearly are treating more lesions outside the cranium," Dr. Régis says. "We also now easily treat multiple brain metastases in a single session – our record was 23 metastases. Some years ago we had been treating between one and three mets in one session, but today we routinely treat patients who have up to 10 mets."

Gamma Knife surgery will play an increasingly critical role in the treatment of multiple metastases as the medical literature continues to show evidence concerning the toxicity of whole brain radiation therapy (WBRT), he adds.

Preventing Blindness with Gamma Knife Radiosurgery

 A pituitary tumor was pressing on Theresa’s optic nerve and, after two brain surgeries, her last hope for saving her sight was Gamma Knife radiosurgery .

In just a few hours, the pin-point laser beams irradiated her tumor and Theresa was on her way home – back to her normal active life. The remarkable non-invasive radiosurgery saved her sight. Today, she is tumor free and enjoying time with her family .

This is her story

Gamma Knife Surgery for Trigeminal Neuralgia

Several options exist for the treatment of trigeminal neuralgia. Medical therapy with carbamazepine, phenytoin and more recently gabapentin has provided good first line treatment. Microvascular decompression, glycerol rhizotomy, radiofrequency rhizotomy, and nerve section have proven effective surgical options. Gamma knife radiosurgery has in recent years become the treatment of choice for people unresponsive to medical therapy. Recent advances in imaging and increased experience with its use, have underscored the importance of gamma knife as a treatment for trigeminal neuralgia .

Gamma Knife Surgery

Gamma Knife offers safe, noninvasive, painless, bloodless neurosurgery. The Gamma Knife is a remarkable tool that allows Neurosurgeons to operate on abnormal areas of the brain without making an incision. Using a technique called stereotactic radiosurgery, the Gamma Knife uses gamma rays produced by 201 cobalt-60 sources to precisely target and destroy abnormalities within the skull. Because the gamma rays are so finely focused, surrounding healthy tissue is not affected
