Clinical Uses
Since August 2001, the CyberKnife system has FDA clearance for treatment of tumors in any location of the body. Some of the tumors treated include: pancreas, liver, prostate, Spinal Lesions, head and neck cancers, and benign tumors.
None of these studies have shown any general survival benefit over conventional treatment methods. By increasing the accuracy with which treatment is delivered there is a potential for dose escalation, and potentially a subsequent increase in effectiveness, particularly in local control rates. However the studies cited are so far limited in scope, and more extensive research will need to be completed in order to show any effects on survival.
In 2008 actor Patrick Swayze was among the people to be treated with Cyberknife radiosurgery.
