CyberKnife Users' Meeting Highlights Major Clinical Data Milestones and Emerging TrendsLarge Scale Study Results Presented in Prostate, Lung and Brain Tumor Treatment
SUNNYVALE, Calif., Feb. 12 (HSMN NewsFeed) -- 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 treatment is playing in reshaping lung cancer care. In fact, during the meeting a majority of the institutions present expressed strong interest in the prospective clinical study that is being led by M. D. Anderson Cancer Center in Houston comparing treatment outcomes with the CyberKnife System versus surgery in early-stage, operable lung cancer.
Along with the enthusiasm around CyberKnife extracranial treatment results, the System remains a widely accepted tool in the treatment of brain tumors. A data comparison of patients with acoustic tumors, treated by either CyberKnife or Gamma Knife radiosurgery demonstrated superior hearing preservation in the patients treated with the CyberKnife System.
"This year's CyberKnife Users' meeting featured clinical data that continue to support the growing usage of CyberKnife technology not only in cancer care, but also the treatment of pain disorders and psychological illnesses," said Eric P. Lindquist, senior vice president and chief marketing officer of Accuray Incorporated. "The meeting provided a forum for data sharing amongst some of the biggest leaders in the medical field, in an effort to provide the most safe, effective and comfortable care for patients."
Emerging CyberKnife treatment applications highlighted at the meeting demonstrated promising results treating patients with breast cancer, bone cancer, kidney cancer and various pain syndromes. Centers continue to explore these applications in the hopes of providing less invasive treatment options to their patients.
