CyberKnife Robotic Radiosurgery
CyberKnife Robotic Radiosurgery
For many cancers, CyberKnife® provides a precise, painless radiation therapy alternative to surgery or traditional radiation therapy.
El Camino Hospital’s cancer program offers the CyberKnife, an advanced form of radiation treatment. CyberKnife, which was invented in Silicon Valley, allows us to eliminate solid tumors 90 percent of the time.
At our Center for Advanced Radiotherapy and CyberKnife Radiosurgery on our Mountain View campus, our staff combines their expertise with compassionate, personalized care to support you throughout your treatment.
Our doctors have extensive experience using CyberKnife for lung cancer, brain and spinal tumors and many other forms of cancer. Combining advanced imaging and CyberKnife technologies, our team pinpoints solid tumors anywhere in your body and delivers radiation treatment to tumors with submillimeter accuracy.
Despite its name, CyberKnife doesn’t require any cutting — which is crucial in certain areas of the body, such as the brain. CyberKnife greatly reduces the risk of damaging critical structures surrounding the tumor and is extremely safe in the hands of our experienced radiation oncologists.
Because you don’t have surgery or anesthesia with CyberKnife, you can receive treatment and go home the same day. The precision of the therapy greatly reduces the number of treatments you require. For example, with prostate cancer, we can perform just four or five sessions of CyberKnife in the same week, rather than multiple treatments over nine weeks with traditional radiation therapy.
What to Expect During CyberKnife Treatment
Before beginning therapy, your doctor takes high-resolution CT or MRI scans to determine the size, shape and location of your tumor. Images are digitally transferred to the CyberKnife system, and one of our specially trained clinicians matches the desired radiation dose to the identified tumor location, while limiting radiation exposure to your surrounding healthy tissue.
During treatment, you lie clothed on a treatment table as the CyberKnife robotic arm moves slowly around you to deliver radiation to the tumor from a number of angles. A treatment session takes 30 to 90 minutes, depending on your type of cancer. If your treatment is being delivered in stages, you’ll return for additional treatments, up to five days.
This is a vast improvement over traditional radiation therapy, which requires daily treatments over several weeks. With traditional radiation therapy, a significant amount of normal tissue is within the field of treatment. To allow these normal tissues to recover, lower doses of radiation must be given over many treatment sessions, and the total amount of radiation is limited.
Because CyberKnife can pinpoint the location of a cancerous tumor with greater accuracy, fewer sessions are required. CyberKnife delivers a minimal dose of radiation to surrounding normal tissues, and often, a much higher dose to the tumor.
You may experience some minimal side effects, such as fatigue or nausea, but those often go away within the first week or two after treatment.
If you have questions or concerns before, during or after treatment, our doctors are readily available to talk with you and do their best to relieve your concerns.
