SUNNYVALE, Calif., Feb. 12 /PRNewswire-FirstCall/ -- Accuray Incorporated (Nasdaq: ARAY), a global leader in the field of radiosurgery, today announced key clinical presentation highlights from the 7th Annual CyberKnife Users' Meeting, which was held January 23-27, 2008 in Scottsdale, Ariz.

At this year's CyberKnife Users' meeting eight presentations reported on large scale studies, each with more than 100 patients with brain, lung or prostate tumors. Particular interest was expressed in prostate cancer treatment results, with multiple studies with two- and three-year follow-up that demonstrated continued and sustained reduction in prostate specific antigen (PSA) levels, and no significant side effects in men treated for prostate cancer using CyberKnife radiosurgery during that period.

"We're pleased that so much progress has been made demonstrating positive outcomes using the CyberKnife System as a non-invasive treatment option for prostate cancer, including durable PSA level reductions up to three years post-treatment," said Michael Santoro, M.D., attending urologist at Winthrop University Hospital's CyberKnife Radiosurgery Center. "Patient satisfaction with the procedure along with an excellent side effect profile is resulting in more and more patient-to-patient referrals."

Additionally lung cancer treatment using the CyberKnife System continued to draw a large amount of interest among the attendees with the presentation of experiences from clinicians around the world treating patients with lung tumors successfully with the CyberKnife System. This further validated the significant role CyberKnife
