September 30, 2011 — The CyberKnife Coalition announced that more than 500 men have been enrolled in the first national patient registry designed to track prostate cancer patients treated with stereotactic body radiation therapy (SBRT). All of the patients were treated with the CyberKnife Robotic Radiosurgery System.
The multi-institutional Registry for Prostate Cancer Radiosurgery (RPCR) tracks clinical and functional outcomes of men with localized prostate cancer treated at academic and community based centers throughout the United States.
Launched in July 2010, the RPCR is an independent, Institutional Review Board (IRB)-approved observational trial registered with clinicaltrials.gov. It is designed to collect information that will be useful in determining the role of radiosurgical treatment for patients with early-stage prostate cancer.
In addition to tracking clinical data the registry also collects patient selection and quality of life information, which will be reported to the Centers for Medicare & Medicaid Services (CMS) and local Medicare contractors.
By participating in the registry, CyberKnife centers will be better equipped to help patients make the best decision for their individual circumstances, a view shared by the Agency for Healthcare Quality and Research. The agency published a patient guide earlier this month entitled 'Knowing your Treatment Options', an overview of prostate cancer treatment options, that for the first time included SBRT as a treatment option for men with localized prostate cancer.
