At Premier Cancer Centers in Dallas, stereotactic radiosurgery and stereotactic body radiotherapy for the treatment of cancer is performed with the CyberKnife M6 system. While it is not surgical or invasive, the CyberKnife has surgical precision through the robotic radiosurgery system to deliver the maximum dose of radiation to the tumor with sub-millimeter accuracy. This means the healthy tissue surrounding the cancer receives minimal radiation to avoid unnecessary damage and side effects. The CyberKnife can be used on almost any area of the body, including the brain, lungs, spine, pancreas, kidney, and prostate. Our board-certified radiation oncologist, works with every patient to teach them about the benefits of CyberKnife stereotactic radiosurgery before creating their unique treatment plan. Schedule a consultation to learn more about the CyberKnife system and learn if it's the best treatment for you.
The CyberKnife system uses advanced technology to provide better radiation therapy than other systems. With a sophisticated image guidance system, the CyberKnife can easily bend and move around the patient while adjusting for any movement of the patient or tumor using motion management and the Synchrony® Respiratory Tracking System. This means patients do not need to be strapped onto the table with rigid frames designed to prevent the patient from moving. The extended reach of the CyberKnife allows is to treat more areas than traditional radiosurgery systems, which typically only treat cancerous and non-cancerous tumors in the head. Another great advantage of the CyberKnife system is the impressive accuracy that delivers precise treatments to the tumor with minimal radiation exposure to the healthy tissue.
Each patient will receive a high-resolution CT scan at our office that will allow the radiation oncologist to create a custom treatment plan with the advanced CyberKnife software. The CT scan will determine the location, shape, and size of the tumor so the radiation oncologist can determine the amount of radiation needed. From there, the treatment plan will calculate how often the patient should receive treatment and an estimated time length.
When the patient arrives for their CyberKnife treatment, they should wear comfortable, loose-fitting clothes that may need to be adjusted or partially removed during the treatment. The patient will be carefully positioned on the table before the CyberKnife treatment begins. Most treatments last about 30 – 90 minutes over the course of several days. All patients are given Saturday and Sunday off to let their body recover from the treatment. Patients may have some side effects that range from fatigue to skin reddening in the treatment area, but this usually only happens in the first 1 – 2 weeks of treatment.
Once a patient has completed their CyberKnife radiation therapy, side effects will disappear quickly and patients will be able to return to their normal activities. Patients should try to take it slow when going back to work or exercise to ease their body back to full function. The doctor will talk to each patient about long-term side effects of the treatment, what is normal after treatment, what they should watch for, and when to schedule follow-up appointments.
