NYCyberKnife at Perlmutter Cancer Center—Manhattan

Most CyberKnife courses are delivered in five sessions or fewer; individual treatment sessions commonly last about 20–30 minutes. Some protocols (in select patients) may use a single fraction. (Source: NYU Langone CyberKnife Center and NYU Langone news about S7 model).

No — CyberKnife treatment is noninvasive (no incisions) and patients do not usually require anesthesia. Treatments are typically pain-free and most people can resume normal activities after each session. (Source: NYU Langone CyberKnife Center).

For prostate SBRT/CyberKnife, physicians may place small fiducial markers to track the prostate during treatment, and may use a rectal spacer (SpaceOAR) to reduce radiation exposure to the rectum, depending on the patient and treatment plan.

Before treatment you will have imaging scans (CT/MRI/PET) for planning; a custom mask or body mold may be made to minimize movement. During each session the robotic arm moves around you while image-guided X-rays verify positioning so highly precise beams target the tumor; side effects are typically minimal.
