Gamma Knife Perfexion Delivers Results for Brain Metastases

Since The Valley Hospital opened the Gamma Knife Center in November 2011, the center’s Leksell Gamma Knife Perfexion system has been used to successfully treat more than 100 brain metastases. And now, preliminary data is demonstrating just how successful this state-of-the-art treatment can really be.

“We’re excited to report that our data analysis has clearly shown that focused radiation using the Perfexion machine offers a significant survival advantage for patients who have brain metastases when compared to more traditional radiation strategies, including whole brain radiation therapy,” says Anthony D’Ambrosio, M.D., Co-Director of the Gamma Knife Center.

Although the majority of patients who come to the Valley Gamma Knife Center present with a single brain tumor, many have more than one tumor. With the Perfexion system, treating multiple tumors in a single visit has proven to be effective and safe. “Ninety-four percent of the tumors we’ve treated with the Gamma Knife Perfexion have stopped growing, decreased in size or disappeared completely within six months of treatment,” Dr. D’Ambrosio says. “Plus, more than 80 percent of these tumors remain well treated a year after gamma knife radiosurgery!” Convenience is also a big plus in Gamma Knife treatment: Because the technology requires only one treatment session, patients are able to continue their chemotherapy without major delays or disruptions in treating their primary condition.

Brain metastases aren’t the only conditions that can be expertly treated using Valley’s Gamma Knife Perfexion system. Learn more about Gamma Knife treatment at Valley for trigeminal neuralgia, arteriovenous malformations (AVM), meningiomas and more.
