Photon-based fractionated stereotactic radiotherapy for postoperative treatment of skull base chordomas.

Objectives: We report our series of skull base chordoma patients who underwent surgical resection followed by high-dose fractionated stereotactic radiotherapy (FSRT) as an alternative to proton radiotherapy (RT).

Methods: Between 2002 and 2009, 12 patients with skull base chordomas without prior radiation history were treated with adjuvant or salvage RT. FSRT with dynamic conformal arcs and intensity-modulated radiation therapy boost was used until 2006 when image-guided intensity-modulated FSRT was instituted.

Control of brain metastases using frameless image-guided radiosurgery.

Object: Radiosurgery is an important and well-accepted method in the management of brain metastases. Using conventional frame-based techniques, high lesional control rates are expected. The introduction of image-guided techniques allows for improved patient comfort and workflow.
