CyberKnife® Therapy for Prostate Cancer

WJMC Urology Specialists - TreatmentsThe CyberKnife® Robotic Radiosurgery System is a viable, non-invasive alternative to surgery for the treatment of tumors anywhere in the body. The treatment – which delivers high doses of radiation to tumors with extreme accuracy – offers new hope to patients who have inoperable or surgically complex tumors, or who may be looking for an alternative to surgery.

The CyberKnife System uses image-guidance and computer controlled robotics to deliver multiple beams of high-energy radiation to the tumor from virtually any direction. Designed to treat tumors anywhere in the body with sub-millimeter accuracy, the CyberKnife System tracks the tumor’s position, detects any tumor or patient movement and automatically corrects the treatment delivery. This outpatient procedure does not require anesthesia or invasive stabilizing frames. Most patients experience minimal recovery time and can return to normal activities almost immediately.

Why is the Cyberknife System Unique?

Accuray has given cancer patients another treatment option with the development of the world’s first and only dedicated radiosurgery device: the CyberKnife Robotic Radiosurgery System. With the CyberKnife System, radiosurgery is no longer limited to treating intracranial tumors. The CyberKnife System is a viable, non-invasive alternative to surgery and is capable of treating tumors anywhere in the body with pin-point accuracy minimizing damage to surrounding healthy tissue and nearby critical structures, such as the spinal cord or the optic nerve.

  • WJMC Urology Specialists - TreatmentsAccurate - Enables clinicians to confidently treat tumors with minimal harm to surrounding healthy tissue by delivering high doses of radiation with sub-millimeter accuracy (within the width of a hair).
  • Flexible - Offers maneuverability and versatility that is unsurpassed by traditional radiation systems. By delivering radiation beams from virtually unlimited positions, the CyberKnife System can treat tumors anywhere in the body from any angle including the brain, spine, lung, liver, pancreas and prostate.
  • Robotic - Continually tracks tumor position, detects any tumor or patient movement and automatically corrects the treatment delivery without the need to manually reposition the patient or interrupt the treatment, thereby slowing down the treatment process.
  • Beneficial - Provides a pain-free, non-invasive alternative for patients, including those diagnosed with previously inoperable or surgically complex tumors, or for patients who are looking for an alternative to surgery.

Treatment Process

Prior to treatment with the CyberKnife® System, the patient undergoes imaging procedures to determine the size, shape and location of the tumor. The process begins with a standard high-resolution CT scan, or for certain tumors other imaging techniques, such as MRI, angiography or PET, may also be used.

Frequently Asked Questions

How does the CyberKnife System differ from other radiosurgery systems?

Radiosurgery has traditionally been restricted to the treatment of tumors in the brain. Patients undergoing traditional radiosurgery for brain tumors are fitted with a rigid metal frame bolted to the skull. This steadies the head during the treatment so that the high doses of radiation can be more precisely targeted at the tumor with minimal damage to other parts of the brain or structures in the head. Frames cause considerable discomfort, may limit the angles from which radiation can be delivered, and make treatment in more than one session difficult. The CyberKnife System is the first and only intelligent robotic radiosurgery system that uses a combination of image guidance and computer controlled robotics to continuously track, detect and correct for tumor and patient movements throughout the treatment. It delivers radiation with pinpoint sub-millimeter accuracy anywhere in the body including tumors in or near the head, spine, lung, prostate, pancreas and liver. Because of the extreme precision and accuracy of the CyberKnife System, no invasive head or body frame is required.

What are the benefits of treatment with the CyberKnife System?

  • More treatment options - The CyberKnife System gives new hope to patients by offering patients with previously inoperable tumors or those who refuse surgery a new treatment option approved to treat tumors anywhere in the body.
  • Precise - The CyberKnife System delivers high-dose radiation with sub-millimeter accuracy, minimizing damage to surrounding healthy tissue.
  • Painless treatment - The CyberKnife System is painless and requires no anesthesia, effectively eliminating the risk of complications such as infections, hemorrhage, and the loss of hearing and/or feeling associated with traditional surgery.
  • No recovery time - Compared to traditional open surgery, CyberKnife treatments are performed on an outpatient basis eliminating overnight hospital stays.
  • Superior comfort - Patients experience improved comfort due to the system’s frame less design which eliminates the pain and inconvenience associated with the head or body frame used to immobilize patients in traditional radiosurgery.
  • Convenience - With an advanced planning system, a patient’s treatment setup can be scheduled at the patient’s convenience, and patients can be treated in as few as one to five visits.

How long does treatment take?

The patient meets with their physician so that imaging required to plan the treatment (e.g. CT, MRI, PET scan) can be performed prior to the CyberKnife treatment to map the tumor. Then the patient visits the medical center for the treatment session that may last anywhere from 30 to 90 minutes. Treatments can be carried out in a single or up to five sessions depending on how the physician has planned the treatment.

Are CyberKnife treatments covered by insurance?

While Accuray cannot guarantee reimbursement from any third-party payer, data collected from U.S. based CyberKnife Centers indicate that over 100 unique commercial and private payers are reimbursing the related codes and any or all portions of the CyberKnife services. Patients should always consult with a physician in connection with any and all treatment options and obtain prior authorization from their insurance companies once a treatment option is determined.
