CyberKnife® for kidney cancer

What is cyberknife?®

CyberKnife® is a non-invasive option for patients who have inoperable or surgically complex tumors, or who may be looking for an alternative to surgery. The CyberKnife system enables our radiation oncologists to deliver high doses of radiation with pinpoint accuracy to a broad range of tumors throughout the body.

Potential benefits of the CyberKnife system include:

  • No incision
  • No pain
  • No anesthesia or hospitalization
  • Greater comfort (patient can breathe normally during treatment)
  • Little or no recovery time
  • Immediate return to normal activities

How it works

The CyberKnife system’s continual image guidance software allows us to deliver high radiation doses with pinpoint accuracy, while automatically correcting for tumor movement. Since radiation beams adjust in real-time to the patient’s breathing cycle, there is less damage to surrounding healthy tissue.

“The CyberKnife VSI is the latest CyberKnife technology available and offers faster, higher radiation energy, as well as upgraded software,” says Dr. Michael Payne, Medical Director of Radiation Oncology.

Prior to the procedure, a high-resolution CT scan determines the size, shape and location of the tumor. The image data is then digitally transferred to the CyberKnife System’s workstation, where we precisely plan treatment to match the desired radiation dose to the exact tumor location.

Once treatment planning is complete, the patient is comfortably positioned on a cushioned table and the system’s computer-controlled robot slowly moves around the table, targeting radiation to the tumor from various angles while sparing surrounding healthy tissue.

The system’s sophisticated software allows us to track the tumor and continually adjust the radiation treatment to account for patient or tumor movement.

Each treatment session lasts between 30 to 90 minutes for one to five days, depending on the location and type of tumor being treated. Patients can typically complete treatment in 1 to 5 days versus several weeks for traditional radiation therapy.

CyberKnife for kidney cancer

A tumor in or near the kidneys can move as you breathe, making it difficult to accurately target with standard radiation. As a result, the tumor may not receive enough radiation and healthy tissue near the tumor may be damaged.

CyberKnife’s sophisticated software and respiratory tracking system allows us to confirm the exact location of the kidney tumor and continually track its movement, in real time, so we can precisely deliver radiation without damaging healthy surrounding tissue.

Also, unlike standard radiation therapy in which the total radiation dose is divided into smaller doses over numerous sessions, CyberKnife allows us to destroy tumors with high radiation doses in four to five sessions, depending on the location of the tumor and other factors.
