First Patients Treated in Yokohama, Japan Following Expanded Japanese Regulatory Approval

SUNNYVALE, Calif., March 19 /PRNewswire-FirstCall/ -- Accuray Incorporated (Nasdaq: ARAY), a global leader in the field of radiosurgery, announced today that the first extracranial patients were treated in Japan using CyberKnife radiosurgery, following the System's recently expanded regulatory approval.

The CyberKnife System (marketed in Japan as CyberKnife II) was previously approved in Japan to treat only intracranial, head and neck tumors. In June 2008 Accuray announced that Japan's Ministry of Health, Labor and Welfare (MHLW) had granted Shonin approval of the CyberKnife System for extracranial treatments, including tumors in the spine, lung, liver, pancreas and prostate. This regulatory approval and the upgraded capabilities dramatically expand the types of patients that can be treated with radiosurgery in the country.

"Having personally treated thousands of patients using CyberKnife radiosurgery, I was thrilled when the technology received Shonin approval for extracranial use," said Kengo Sato, M.D., chief medical officer at Yokohama CyberKnife Center in Yokohama, Japan. "I have seen firsthand the System's benefits in treating brain tumors and am very happy to be able to extend those benefits to our extracranial patients. We're now treating patients who were previously considered untreatable and are very pleased with the results we're seeing."

"Japan remains the second largest installed base of CyberKnife Systems with more than 20 installed to date, so these extracranial treatments are just the beginning," said Eric P. Lindquist, senior vice president and chief marketing officer of Accuray. "These patients are the first of many to experience a convenient, comfortable and precise form of cancer care."

About the CyberKnife(R) Robotic Radiosurgery System

The CyberKnife Robotic Radiosurgery System is the world's only robotic radiosurgery system designed to treat tumors anywhere in the body non-invasively. Using continual image guidance technology and computer controlled robotic mobility, the CyberKnife System automatically tracks, detects and corrects for tumor and patient movement in real-time throughout the treatment. This enables the CyberKnife System to deliver high-dose radiation with pinpoint precision, which minimizes damage to surrounding healthy tissue and eliminates the need for invasive head or body stabilization frames.
