CYBERKNIFEMariah Cordie and Deb Norrell

What is CyberKnife?

World’s first and only robotic radiosurgery system designed to treat tumors throughout the body non-invasively.

Procedure

Prior to procedure, CT is needed to determine size, shape, and extent of tumor.

Treatment plan is created Each treatment session will last between

30-90 minutes depending on tumor type and location

Hypofractionation is used Will be treated over 1-5 days

History

Developed by John Adler, MD First patient was treated in 1994 with a

prototype Approved by FDA in 2001 First approved CyberKnife appeared at

Stanford in Oct. 2001 Stanford opened 2nd unit in 2006- first

institution in the world to have 2 Cyberknife units in operation.

Benefits

It provides pain-free, non-surgical option for patients who have inoperable or surgically complex tumors.

No anesthesia or hospitalization needed Greater comfort (patient can breathe

normally during treatment) Little or no recovery time Immediate return to normal activities

What does it treat?

Cancerous and non-cancerous tumors anywhere in the body.

Prostate Lung Brain Liver Spine Pancreas Kidney

Side effects

Acute:NauseaFatigueInjury to nearby tissues

Prostate: constipation, urinary retention, blood in stool, injury to bladder wall, and erectile dysfunction

Brain: Headache, increase intracranial pressure, seizures, edema, necrosis, and neural tissue injury

Advances in Technology Synchrony® Respiratory Tracking

System This tracking system continuously synchronizes

beam delivery to the motion of the tumor, allowing clinicians to significantly reduce margins, while eliminating the need for gating or breath-holding techniques.

RoboCouch® Patient Positioning System This robotic system precisely aligns patients

enabling faster patient setup.
