Intra-operative electron beam radiotherapy for newly diagnosed and recurrent malignant gliomas: feasibility and long-term outcomes.

Introduction: Intra-operative electron beam radiotherapy (IOERT) is an alternative to dose escalation for the treatment of central nervous system tumors. The objective of this study was to describe the feasibility and long-term outcomes of IOERT in the treatment of primary and recurrent gliomas.

Materials And Methods: From January 1992 through December 2002, all patients treated with IOERT at the Hospital San Francisco de Asis, Madrid/Spain were retrospectively reviewed.

Stereotactic radiosurgery as a salvage treatment option for atypical meningiomas previously submitted to surgical resection.

Background: Surgery is the initial treatment for atypical meningiomas (AM), but in cases of recurrence, options become more limited. We present our results from salvage treatment with stereotactic radiosurgery (SRS) in previously surgically treated patients.

Methods: Sixteen patients treated between 1993 and 2007 were retrospectively reviewed.
