Surgeons at South Sound Gamma Knife at St. Joseph now use the latest Gamma Knife® technology for even greater precision to reduce or eliminate tumors or lesions in the brain without traditional surgery. Gamma Knife is widely recognized as the gold standard for stereotactic radiosurgery in the brain. Perfexion™, the first full redesign of the Gamma Knife in 30 years, improves access to tumors at the base of the skull and offers single-session, leading-edge treatment for multiple metastatic tumors. Perfexion greatly reduces treatment times for improved patient comfort.

“Gamma Knife radiosurgery treatment benefits patients with malignant and benign brain tumors, vascular malformations, trigeminal neuralgia and essential tremor,” said Neurosurgeon Daniel Nehls, MD, a member of the South Sound Gamma Knife team and a practicing physician at Neurosurgery Northwest – Tacoma, part of Franciscan Medical Group. “Response may be seen in just a few weeks or over several months, depending on the condition treated.”

Despite the name, Gamma Knife is actually a bladeless procedure. There is no incision in the skull so the risk for complications is minimal. Gamma Knife can be an option for many patients who were previously not candidates for traditional brain surgery due to advanced age, co-existing health problems or high-risk medical illness.

“Gamma Knife differs from conventional radiation therapy because patients receive highly targeted radiation delivered to a specific focal area of the brain,” said Radiation Oncologist Randy Sorum, MD, co-medical director for the program and a practicing physician at Tacoma Radiation Oncology Centers.  “As a result, they do not experience side effects commonly associated with traditional radiation therapy.”

Gamma Knife Perfexion focuses 192 converging beams of high-dose Cobalt60-generated photons on a computer-mapped target.  Sophisticated, three-dimensional treatment planning provides extreme precision and makes it possible to administer a high radiation dose to the lesion without damaging surrounding healthy tissue.

During Gamma Knife therapy, patients receive local anesthesia, remain awake during the procedure and experience little, if any, discomfort. Treatment generally requires just a single session and patients usually go home the same day. Most individuals resume normal activities within 48 hours.

“We are committed to using state-of-the-art technology to provide our patients with the best treatments that can maintain or improve their quality of life,” said Neurosurgeon Peter Shin, MD, co-medical director for South Sound Gamma Knife and a practicing physician at South Sound Neurosurgery. “Gamma Knife can be an effective and non-invasive treatment option for many patients.”

South Sound Gamma Knife is a partnership between St. Joseph Medical Center, part of Franciscan Health System, and Tacoma/Valley Radiation Oncology Centers. Gamma Knife stereotactic radiosurgery is performed at St. Joseph Medical Center in Tacoma. The experienced team of neurosurgeons and radiation oncologists at South Sound Gamma Knife has performed more than 440 procedures since opening in late 2005.

Gamma Knife therapy is a benefit of most medical insurance plans, including Medicare and Medicaid. For more information about Gamma Knife technology visit www.SouthSoundGammaKnife.com or call 253-284-2438.
