Optune is a noninvasive regional therapy that targets dividing cancer cells in the brain and generally does not harm healthy cells. Optune works by creating alternating, “wave-like” electric fields called Tumor Treating Fields (TTFields).
TTFields travel across the upper part of the brain in different directions to help slow or stop recurrent glioblastoma cancer cells from dividing.
Optune is delivered through 4 transducer arrays that are placed directly on the scalp to target the tumor. The transducer array placement is determined based on each patient’s MRI results to maximize the therapy’s effect on the tumor.
