Enhanced Capabilities Enable More Patients to Benefit from CyberKnife Treatment

SUNNYVALE, Calif., Oct. 29 /PRNewswire/ -- Accuray Incorporated (Nasdaq: ARAY), a global leader in the field of radiosurgery, announced today feedback from Creekside Cancer Care on their use of the CyberKnife VSI System.  Creekside Cancer Care was the first facility in the world to install and begin treating patients with the CyberKnife VSI System.  Patient treatments began in June 2010 and clinicians at Creekside Cancer Care quickly reported that average treatment times are less than 30 minutes.

The CyberKnife VSI System, launched in November 2009, is the latest addition to the CyberKnife product family.  The CyberKnife VSI System leverages the versatility, simplicity, and intelligence of the CyberKnife System to broaden the range of treatment options physicians can offer their patients - from radiosurgery to include conventionally fractionated Robotic IMRT™.  The CyberKnife VSI System features a world-class 1,000 MU/minute X-band linear accelerator, advanced visualization capabilities, automated segmentation capabilities and logical workflow enhancements designed to streamline the physician and patient experience.

To date Creekside Cancer Care has treated more than 45 patients using the new CyberKnife VSI System across a variety of indications including prostate, head and neck, lung, spine and liver.  In addition to traditional intracranial radiosurgery and expanded whole body radiosurgery, clinicians at Creekside are regularly using the latest capability of the CyberKnife VSI System, Robotic IMRT, to address prostate cancer.  The enhanced spectrum of treatment options allows for more customized treatment plans based on patient-specific situations and conditions, such as patients requiring re-irradiation of previously treated areas, or patients requiring partial breast irradiation.  Other examples of where they have found expanded fractionation capabilities useful have been in the treatment of spine, hip and head and neck lesions.

Creekside clinicians report that one of the greatest advantages of the CyberKnife VSI System is the user's ability to adapt to a wider variety of planning objectives based on the clinical situation and then seamlessly deliver a treatment.  They note that treatment delivery features, such as time based intra-fraction imaging, dramatically reduce the time on the table for patients.

"The CyberKnife VSI System enables our physicians, therapists, and physicists to have more flexibility when prescribing and delivering treatment," said Lee McNeely, M.D., of Creekside Cancer Care.  "Because we have been routinely able to deliver treatment in less than 30 minutes, we have greatly improved the patient experience."

"It is encouraging to hear directly from our customers that the CyberKnife VSI System is achieving the intended goal of improving patient care," said Euan S. Thomson, Ph.D., president and CEO of Accuray.  "We look forward to working with existing and new customers to incorporate the enhanced capabilities the CyberKnife VSI System offers into their cancer programs so they can expand the patient population that can benefit from CyberKnife treatments."

Dr. McNeely, who has treated more than 2,000 CyberKnife cases in his career, will present a discussion of Creekside Cancer Care's early CyberKnife VSI experience and further potential clinical opportunities at the Annual Meeting of the American Society for Radiation Oncology (ASTRO) on Monday, November 1, 2010 from 2:45 p.m. to 3:00 p.m. PT and Tuesday, November 2 from 4:15 p.m. to 4:30 p.m. PT.
