At Las Vegas CyberKnife Center, we offer patients new hope in treating lung tumors with our advanced, non-invasive CyberKnife System. This highly precise radiation therapy allows us to address your lung tumors without invasive surgery or the complications commonly associated with conventional radiation therapy.
The CyberKnife System is designed to deliver stereotactic body radiotherapy (SBRT), and has been in use since 2001, when it was approved by U.S. Food and Drug Administration to treat tumors anywhere in the body, including the lung. The CyberKnife System delivers high doses of radiation directly with pinpoint accuracy to lung tumors. Its advanced robotic design and sophisticated tumor-tracking technologies makes CyberKnife the only technology available to treat tumors while in motion and maintain sub-millimeter accuracy. Treatments are completed on an outpatient basis over the course of one to five consecutive days, compared to conventional radiation therapy treatments that are deliver low dose radiation over the course of 25 to 45 days. Most patients experience minimal to no side effects, and can resume normal daily activities after each treatment session.
Because of the combination of its advanced technologies, the CyberKnife System is often an effective option for patients in poor health who may not be able to tolerate lung cancer surgery due, or those who are looking for a minimally invasive treatment and alternative to surgery.
One of the biggest problems with conventional radiation therapy for lung cancer has been the techniques used to treat tumors in the lung that move as the patient breathes. Conventional radiation therapy requires the use of uncomfortable and painful gating, breath hold or compression techniques to try to minimize patient and tumor movement as much as possible, and result in healthy surrounding tissue receiving radiation during the lung cancer radiation treatment, as well.
With its real-time imaging, tumor-tracking technology and flexible robotic radiation delivery capabilities, the CyberKnife System eliminates problems associated with conventional radiation therapy and has been shown in studies to be a viable alternative to surgery. The CyberKnife System can track the movements of the tumor throughout lung cancer radiation therapy and adjust the position of the radiation beam to ensure precise delivery.
Depending on the size, location density of your tumor, doctors may need to insert fiducial markers into your lung to help the CyberKnife System track the tumor location and movement during treatment. Fiducials are about the size of a grain of rice and are gold in color. If doctors determine you need them to help the CyberKnife System track your tumor’s movements, then three to five of them will be placed into your tumor using a small needle. The fiducials may move slightly after placement, so you will wait one week before treatment starts, to ensure the fiducials are stabilized. Not all patients require fiducials; your need will be assessed by our cancer experts.
