All-Purpose Units Rarely Utilized for Radiosurgical Treatments

SUNNYVALE, Calif., March 6 /PRNewswire-FirstCall/ -- Accuray Incorporated (Nasdaq: ARAY), a global leader in the field of radiosurgery, announced today results of an independent survey, which concluded that the CyberKnife(R) Robotic Radiosurgery System is the only extracranial radiosurgery technology in widespread, routine clinical use.

The survey also showed that hospitals with all-purpose units -- which combine radiotherapy and radiosurgery systems -- rarely use the devices for extracranial radiosurgery treatments. In fact, on average, each all-purpose unit was used to treat only five patients per year with extracranial tumors, compared to approximately 91 extracranial patients treated with each CyberKnife System.

In its second year, this survey charts the rapid growth of radiosurgery for treatment of extracranial tumors and reinforces findings from 2006, which also indicated the CyberKnife System was the most widely used device for extracranial radiosurgery. Last year approximately 50 percent of the CyberKnife Systems were used half of the time or more for extracranial treatments. This year, survey data show that 74 percent of CyberKnife Systems are now used half of the time or more to treat extracranial tumors. In contrast, less than 1 percent of all-purpose units currently are used at this level. This low usage suggests that these devices have virtually no measurable impact on the rapidly expanding extracranial radiosurgery market. In contrast, 100 percent of CyberKnife Systems are being utilized for some type of extracranial procedure, with prostate, lung and spine treatments increasing most dramatically over the past year.
