"With GammaTile, we can deliver radiation directly to the tumor site at the time of surgery without any delay," said Dr. Charles G. Kulwin, a neurosurgeon at Goodman Campbell Brain and Spine. "We are proud to provide such an innovative treatment option at Goodman Campbell Brain and Spine and be recognized as a GammaTile Center of Excellence. We are always looking for opportunities to give patients hope where options have been historically limited."
GammaTile is an innovative form of radiation therapy placed at the time of tumor removal surgery, delivering immediate, targeted radiation to the tumor site when cancer cells are at their lowest levels. Unlike conventional approaches, which often require a delay between surgery and radiation therapy to allow for wound healing, GammaTile eliminates this treatment gap. By delivering immediate, localized radiation directly at the tumor site, it is designed to maximize the treatment's effectiveness against remaining cancer cells and reduce the risk of regrowth.1
