Stereotactic Radiosurgery: Benign Indications

Radiotherapy and radiosurgery for benign skull base meningiomas

Meningiomas located in the region of the base of skull are difficult to access. Complex combined surgical approaches are more likely to achieve complete tumor removal, but frequently at a cost of treatment related high morbidity. Local control following subtotal excision of benign meningiomas can be improved with conventional fractionated external beam radiation therapy with a reported 5-year p...

Fractionated stereotactic conformal radiotherapy for large benign skull base meningiomas

PURPOSE To assess the safety and efficacy of fractionated stereotactic radiotherapy (FSRT) for large skull base meningiomas. METHODS AND MATERIALS Fifty-two patients with large skull base meningiomas aged 34-74 years (median age 56 years) were treated with FSRT between June 2004 and August 2009. All patients received FSRT for residual or progressive meningiomas more than 4 centimeters in grea...

Single Fraction Stereotactic Radiosurgery for Retreatment of Skull Base Recurrent Head and Neck Malignancies

INTRODUCTION Recurrent head and neck carcinomas are notoriously difficult to treat. Salvage surgery, brachytherapy, and repeat external beam radiotherapy have all been utilized, achieving modest local control at the expense of elevated toxicity. We performed a retrospective review to evaluate the efficacy of single fraction stereotactic radiosurgery (SRS) for the treatment of recurrent head and...

Radiosurgery and Hypofractionated Stereotactic Irradiation with Photons or Protons for Tumours of the Skull Base

Recent technological advances in photon-RT have allowed an improvement in targeting accuracy, dose escalation, delivery of multiple large fractions (hypofractionated stereotactic radiation therapy HSRT) or single fraction stereotactic ablative radiation therapy (radiosur‐ gery SRS). Radiosurgery delivers a single large dose with very steep dose fall-off outside the lesion to very small volumes ...
