Elekta: New Treatment with Leksell Gamma Knife Perfexion Introduced in Japan

STOCKHOLM, Sweden--(HSMN NewsFeed)--Leksell Gamma Knife® Perfexion™, Elekta's (STO:EKTAB) new system for stereotactic radiosurgery, has been used for the first time to treat patients at the Jiro Suzuki Memorial Gamma House, Furukawa Seiryo Hospital, in Miyagi, Japan.

The 100-bed hospital has a strong neurosurgery program, and is the first in Japan to offer treatment with Leksell Gamma Knife Perfexion, an advanced radiosurgery treatment system for intracranial stereotactic radiosurgery or Gamma Knife® surgery.

“We are pleased to be able to offer our patients the benefits of treatment with Leksell Gamma Knife Perfexion," says Dr. Hidefumi Jokura, Vice President of Furukawa Seiryo and director of the hospital's Gamma Knife Center. "The sophistication of the technology is allowing us to treat more patients in less time. And importantly, both staff and patients appreciate the greater efficiency of the design, which results in reduced hospital visitation for the patient."

Dr. Hidefumi Jokura and his colleague, Dr. Kawagishi, reported that they treated 107 cases, 60 percent of them were brain metastases, during the two first months. “With Leksell Gamma Knife Perfexion, we now have the capability to treat 3-4 patients in just half a day – a process that normally would have taken a full working day,” says Jokura.

Leksell Gamma Knife is in daily use in over fifty centers in Japan and Furukawa Seiryo hospital currently utilizes Gamma Knife surgery to treat around 500 patients each year.

"With Leksell Gamma Knife Perfexion, we are further realizing our ambition of offering effective treatments for a wide range of neurological challenges; and are achieving this with a greater degree of positive outcomes and shorter patient treatment times than before," says Hideo Watanabe, Managing Director, Elekta Japan.

About Leksell Gamma Knife® Perfexion™

Leksell Gamma Knife® Perfexion™, the latest version of Leksell Gamma Knife systems, is a complete system for intracranial stereotactic radiosurgery or Gamma Knife® surgery. Perfexion is the most advanced radiosurgery system on the market for head treatments. Specifically designed to treat multiple targets, such as brain metastases, improve patient comfort and treatment time through advanced automation. The treatment applications have also been extended to include all areas of the head.

The non-invasive treatment is shaped by 192 simultaneously focused beams of ionizing radiation that have sufficient penetration to reach even the most deeply seated tumors. The system delivers prescribed doses/shots of radiation, in compliance with a treatment plan, to the exact target site, thereby sparing surrounding tissues. Gamma Knife surgery has many advantages. The risk of complications, as compared to open surgery, is less and it is a gentler form of treatment for the patient. Gamma Knife surgery can normally be performed in a day, and convalescence is extremely short. The technique, supported by over three decades of clinical practice, is performed for over 50,000 patients each year. To date, more than 500,000 patients around the world have undergone Gamma Knife surgery.
