CyberKnife Radiation Cancer Treatment at Medical City Dallas

No anesthesia. No incision. No recovery time.

What is CyberKnife® M6?

CyberKnife® M6 provides a non-surgical option for patients who have inoperable or surgically complex tumors, or who may be looking for an alternative to surgery. It is a non-invasive alternative to surgery that involves no cutting. CyberKnife M6 treats cancerous and noncancerous tumors through a radiation delivery device mounted on a robotic arm.

The flexibility of the robotic arm enables CyberKnife M6 to deliver radiation to tumors anywhere in the body, including the brain, head and neck, spine, lung, prostate, liver, pancreas, breast and other soft tissues. Sophisticated software and advanced imaging tracks tumor and patient movement and adjusts the beams of high-dose radiation to ensure that a patient’s treatment is delivered with a high degree of accuracy.

Patients can complete treatment in one to five treatments, compared to the weeks it takes to complete a course of conventional radiation therapy.

Is CyberKnife safe?

The CyberKnife is cleared by the FDA to treat tumors anywhere in the body. And because of its precision, CyberKnife spares healthy tissue surrounding the targeted area in a manner not achievable with traditional radiation therapy.

Benefits of Using CyberKnife® M6 treatment

  • Non-invasive
  • No anesthesia required
  • Outpatient procedure
  • Exceptional accuracy decreases radiation to healthy tissue and organs
  • No recovery time
  • Immediate return to normal activity
  • No invasive head or body frame
  • No breath holding or “respiratory gating” required during treatment
  • Quicker treatment times
  • Ability to treat broader array of tumors

What makes CyberKnife® M6 unique?

The revolutionary CyberKnife® M6 safely treats tumors with pinpoint accuracy. It is so precise that radiation can be matched to the shape of small, complex tumors located near critical structures. CyberKnife M6 does not require invasive head or body frames to stabilize patient movement, because it continuously tracks, detects and corrects whenever the patient moves during treatment. CyberKnife M6 also treats many lesions that may be considered inoperable or untreatable with other radiosurgery systems — giving many patients new hope. Patients can complete treatment in one to five treatments. This is a significant advantage over conventional radiation therapy, which can require up to eight weeks of daily treatments.

RoboCouch® Patient Positioning System

The RoboCouch® System is the world’s most advanced patient positioning system. It enables sub-millimeter accuracy for full-body radiosurgery.

This state-of-the-art equipment provides a high degree of accuracy and quickly places patients in the planned treatment position for radiosurgery.

CyberKnife® M6 treats

  • Brain and spine tumors
  • Lung tumors
  • Liver and pancreatic cancers
  • Prostate cancer

The simple outpatient treatment process includes:

Step #1 - Consultation

The patient is seen by both a radiation oncologist and a surgeon.

Step #2 - Imaging (Simulation)

Each patient will be placed in a unique treatment position and will undergo a CT scan in that position. This scan will offer a three dimensional reproduction of the patient’s body so that the treating physicians can identify the exact size, shape and location of the tumor and the surrounding vital structure. MRI and/or PET-CT scans may also be required.

Step #3 - Treatment Planning

The radiation oncologist will work with a certified physicist to generate a computerized treatment plan. Advanced software will help the CyberKnife team determine the number, intensity and direction of the radiation beams to be delivered by the robotic arm. This plan will typically utilize one to two hundred radiation beams to provide the desired radiation dose to the tumor while minimizing radiation to the adjacent healthy tissue.

Step #4 - Treatment

The patient is asked to relax and lay still during the CyberKnife procedure. No anesthesia is necessary. The CyberKnife M6 robot will move slowly around the patient to deliver the radiation. The imaging system regularly verifies target position to ensure the radiation is being accurately delivered. The entire procedure typically lasts 30-60 minutes. Following treatment, the patient may immediately return to normal activities.

Insurance Considerations for CyberKnife Patients

CyberKnife treatments are usually covered by Medicare and by most private insurance providers. Our staff will contact insurance providers to assist with pre-authorization requirements before treatment. Medical City Dallas' CyberKnife program is a part of the Radiation Oncology Department at Medical City Dallas. Our team strives to provide high quality, radiation oncology care in an interdisciplinary setting and to provide state-of-the-art care in selected clinical areas.
