SUNNYVALE, Calif., Dec. 15, 2010 /PRNewswire-FirstCall/ -- Accuray Incorporated (Nasdaq: ARAY ), a global leader in the field of radiosurgery, announced today that the U.S. Food and Drug Administration (FDA) has granted the company 510(k) clearance to market Lung Optimized Treatment, a new component of the CyberKnife® VSI™ System. The 510(k) clearance enables Accuray to provide physicians with greater flexibility in delivering radiosurgery treatments to patients with lung cancer, the most common and deadly cancer worldwide.
Recent studies have found radiosurgery to be an effective treatment option for medically inoperable lung cancer patients as it provides good local control and survival rates. Treating these tumors is particularly complex due to movement with respiration and nearby critical structures. This is especially the case for central and chest wall tumors, which are located in close proximity to such critical anatomical structures.
Lung Optimized Treatment offers the accuracy and steep dose fall off required to safely treat lung tumors, even those close to such critical structures. Simulation and comparison workflows, combined with unique tracking modes, allow the clinician to select from multiple, non-invasive options, providing lung SBRT patients the optimal non-invasive treatment option, regardless of tumor location.
"Lung Optimized Treatment is a new tool we developed to meet the clinical demand for more flexibility in treating lung cancer patients with radiosurgery and the desire to move away from reliance on fiducial markers," said Chris A. Raanes, senior vice president and chief operating officer for Accuray. "This new technology enables treatments throughout the lung without a single incision, all while safeguarding healthy tissue and structures around the tumor to ensure they are not damaged by radiation."
