Cyberknife Stereotactic Radiosurgery for Intracranial Chordomas

Abstract

Introduction: Intracranial chordomas are rare malignant skull base tumors representing less than 1% of all intracranial neoplasms. Chordomas are locally aggressive with high recurrence rates regardless of the treatment. As a more convenient alternative to 8 weeks of standard post-operative fractionated radiotherapy we present the Stanford experience with skull base chordomas treated with CyberKnife (CK) stereotactic radiosurgery (SRS).
