First noninvasive thermal ablation of a brain tumor with MR-guided focused ultrasound


Coluccia, Daniel; Fandino, Javier; Schwyzer, Lucia; O’Gorman, Ruth; Remonda, Luca; Anon, Javier; Martin, Ernst; Werner, Beat (2014). First noninvasive thermal ablation of a brain tumor with MR-guided focused ultrasound. Journal of Therapeutic Ultrasound, 2:17.

Abstract

Magnetic resonance-guided focused ultrasound surgery (MRgFUS) allows for precise thermal ablation of target tissues. While this emerging modality is increasingly used for the treatment of various types of extracranial soft tissue tumors, it has only recently been acknowledged as a modality for noninvasive neurosurgery. MRgFUS has been particularly successful for functional neurosurgery, whereas its clinical application for tumor neurosurgery has been delayed for various technical and procedural reasons. Here, we report the case of a 63-year-old patient presenting with a centrally located recurrent glioblastoma who was included in our ongoing clinical phase I study aimed at evaluating the feasibility and safety of transcranial MRgFUS for brain tumor ablation. Applying 25 high-power sonications under MR imaging guidance, partial tumor ablation could be achieved without provoking neurological deficits or other adverse effects in the patient. This proves, for the first time, the feasibility of using transcranial MR-guided focused ultrasound to safely ablate substantial volumes of brain tumor tissue.
