Progressive meningioma continues to grow despite surgery and/or radiation therapy. The purpose of this study is to assess the use of a device called the NovoTTF-100A System for treating progressive meningioma. This portable device is approved for treating a form of brain cancer called glioblastoma multiforme, but its use for treating meningioma is considered investigational.
Patients wear the sticky pads of the NovoTTF-100A System on their scalp. The device transmits electrical fields through the skull which are intended to kill cancer cells. Patients can learn how to put on the device at home and can wear it throughout the day while they go about their regular activities.
