Neuroanatomical target theory as a predictive model for radiation-induced cognitive decline Objective:In a retrospective review to assess neuroanatomical targets of radiation-induced cognitive decline, dose volume histogram (DVH) analyses of specific brain regions of interest (ROI) are correlated to neurocognitive performance in 57 primary brain tumor survivors. Methods:Neurocognitive assessment at baseline included Trail Making Tests A/B, [...]

Stereotactic Radiosurgical Salvage Treatment for Locally Recurrent Esthesioneuroblastoma BACKGROUND: Esthesioneuroblastoma (ENB) is a rare malignant neuroendocrine tumor considered to be radiation sensitive. Local recurrence may be treated in a variety of ways, including stereotactic radiosurgery (SRS); however, little information on its effectiveness is available. OBJECTIVE: To determine whether SRS is effective in providing local control [...]

Abstract Temozolomide is known to penetrate the blood–brain barrier and sensitize brain tumors to radiation and has been used clinically to sensitize fractionated external beam radiotherapy. However, there are limited prospective clinical data available on the safety of temozolomide as a chemosensitizing agent administered with stereotactic radiosurgery. This is a phase I trial of previously [...]

BACKGROUND: Radiosurgery is the main alternative to microsurgical resection for benign meningiomas. OBJECTIVE: To assess the long-term efficacy and safety of radiosurgery for meningiomas with respect to tumor growth and prevention of associated neurological deterioration. Medium- to long-term outcomes have been widely reported, but no large multicenter series with long-term follow-up have been published. METHODS: [...]

Journal of Neurosurgery, Volume 0, Issue 0, Page 1-8, Ahead of Print. Epilepsy surgery is an effective treatment for medically resistant temporal lobe epilepsy (TLE). To minimize complication rates and potentially improve neuropsychology outcomes, stereotactic radiosurgery (SRS) has been explored as an alternative. Two pilot trials have demonstrated the effectiveness of SRS for the treatment [...]
