There are many common misconceptions surrounding gamma knife radiosurgery. What’s the truth behind them? Here, Chad DeYoung, M.D., Co-Director of the Gamma Knife Center, shares clinical evidence to separate fact from fiction.
Dr. DeYoung says:
“Introduced more than 40 years ago, gamma knife radiosurgery has been around longer than the CyberKnife, Novalis, TrueBeam and other radiosurgery systems—so naturally, there’s more research to support it.
“Other systems have expanded their use over time to include brain tumors, but gamma knife radiosurgery is the only technology built solely to treat conditions of the brain, head and neck. It’s taken years for other systems to catch up to the power and sophistication that gamma knife radiosurgery offers.”
Dr. DeYoung says:
“All radiosurgery systems, including the gamma knife, can deliver the accurate radiation dose to a tumor. What’s just as important, however, is the amount of radiation that doesn’t reach healthy tissue—and that’s where gamma knife radiosurgery offers a critical advantage.
“Gamma knife surgery can treat more brain lesions, and spare more healthy tissue, than other technologies. This is especially beneficial for brain metastases, a condition in which patients may need treatments for multiple tumors. It’s important to choose the system that will offer the most effective way to target multiple lesions in a single treatment while minimizing the radiation dose to healthy tissue.”
