CyberKnife® Hero


A non-surgical alternative to traditional cancer treatments

New call-to-action

Imagine a nonsurgical way to treat both cancerous and noncancerous tumors anywhere in the body, including the brain, liver, kidney, neck, spine, lung, pancreas and prostate. Now imagine that it were pain-free and caused fewer side effects than did other treatments. The CyberKnife® Robotic Stereotactic Radiosurgery System makes all that a reality.

CyberKnife is the world's most accurate radiosurgery instrument for treating tumors and lesions that were once considered inoperable. Saint Peter's University Hospital is one of a select group of medical institutions in the country currently offering the breakthrough CyberKnife treatment.

CyberKnife is a robotic stereotactic radiosurgery system that noninvasively treats inoperable or complex tumors. It delivers beams of high-dose radiation with pinpoint accuracy in a manner that does not cause any patient discomfort, nor does it require minimizing patient movement, as do other methods do.

During the treatment set-up appointment, the patient undergoes a CT scan with contrast (iodinated dye), which is then used to precisely plan delivery of radiation to the tumor. In some instances, an MRI scan may also be necessary in order to fully visualize the tumor and affected area(s).  Depending on the treatment plan, small metal or gold markers (called fiducials) may be implanted to accurately target radiation from the CyberKnife. These markers are only three to four millimeters long and are implanted on an outpatient basis. Other patients may be fitted with a Synchrony tracking vest, which, like the markers, tracks tumor movement during treatment.
