CyberKnife Radiosurgery for Organ-Confined Prostate Cancer: Homogenous Dose Distribution
Prospective Evaluation of CyberKnife Stereotactic Radiosurgery for Low and Intermediate Risk Prostate Cancer: Homogenous Dose Distribution
Sponsor: Accuray Incorporated
Listed as NCT00643994, this NA trial focuses on Cancer of the Prostate and Prostate Cancer and remains completed. Sponsored by Accuray Incorporated, it has been updated 12 times since 2007, reflecting substantial change activity. This study contributes to the evolving evidence base for cancer treatment protocols.
Study Description(click to expand)The CyberKnife Robotic Radiosurgery System is a unique radiosurgical system capable of treating tumors anywhere in the body noninvasively and with sub-millimeter accuracy. The CyberKnife System delivers radiation using a precise targeting methodology allowing a focal treatment margin around the target, thus limiting the volume of adjacent tissue receiving high doses radiation. This in turn allows the delivery of high doses of radiation to the prostate over a short series of treatments.
