Moving tumors. Head, neck and spine tumors stay put, but tumors in organs (like the lungs, kidney, liver and pancreas) “move.” Because they can shift with each breath, these tumors are particularly challenging to address with precision. St. Anthony’s state-of-the-art CyberKnife with Synchrony technology (the only one in Oklahoma City) tracks where tumors are from moment to moment, allowing our doctors to focus tight beams of radiation directly on the tumor, barely touching any healthy tissue nearby. CyberKnife is painless, non-invasive radiation therapy.
Options mean hope. A tumor may be considered inoperable because it’s small, or it’s a complex shape, or it moves (or all three). CyberKnife changes all that, offering hope instead. Astrid Morrison, MD and St. Anthony radiation oncologist, said, “With our CyberKnife System, we can offer our tumor patients new treatment options that simply weren’t possible before.”
How it works: A guidance system tracks and verifies where the tumor is. The Synchrony predictive software compensates for the patient’s (and therefore the tumor’s) movements, directing CyberKnife’s sophisticated robotic arm and radiation beam at it with pinpoint accuracy. CyberKnife is so precise, in fact, that it’s called “T4”—that is, “tight-to-the-tumor”—radiosurgery.
So far, CyberKnife technology has been used to treat more than 60,000 patients worldwide. As just one example, because CyberKnife is so unlike other types of brain surgeries—no scalpels, incisions, or conventional head frames affixed to your skull—most patients can actually drive themselves home immediately following their surgery!
“For your treatment, you lie on the table in your street clothes, wearing a simple mesh facemask or body immobilizer custom-fit to you,” explains radiologist Marianne M. Young, MD.
Treatment of Prostate Cancer. Medicare now covers CyberKnife to treat prostate cancer for patients living in Oklahoma. Now more patients may take advantage of the many benefits of CyberKnife treatment for prostate cancer patients including brief treatment time, an immediate return to normal activities post-treatment and a high rate of erectile function preservation. Published five-year data demonstrated positive, long-term outcomes for prostate cancer patients treated with CyberKnife.
