Radiosurgery for Chordoma and Chondrosarcoma

Abstract

Chordomas and chondrosarcomas are rare locally aggressive skull base tumors with high progression or recurrence rates. Ultimately, they have high mortality rates unless they respond to multimodality management options that include one or more surgical resections, fractionated radiation therapy, and stereotactic radiosurgery (SRS). SRS has become a standard management option for recurrent or residual chordomas and chondrosarcomas after failed surgical resection and fractionated radiation therapy. This report examines the role of SRS in these skull base tumors.
