Case ReportsSpinal cord anaplastic oligodendroglioma with 1p deletion: report of a relapsing case treated with temozolomide.
Primary spinal cord oligodendroglial tumor is very rare, and in only one patient with spinal cord oligodendroglioma has a deletion of chromosome 1p/19q been reported. We present the case of an 18-year-old girl, who had one-year lower back pain and one-month lower limb weakness. Magnetic resonance images of the spinal cord showed an intramedullary mass from level T8 to T10, which was then radically removed. ⋯ The most recent MRI of brain and spinal cord showed postoperative changes without evidence of tumor recurrence of the spine and oligodendrogliomatosis along the cerebral-spinal axis. To our knowledge, this is the first report of a recurrent anaplastic oligodendroglioma with 1p deletion occurring in the spinal cord. It is also the first case of the patient with recurrent intramedullary anaplastic oligodendroglioma who had a significant clinical improvement and complete imaging remission after subtotal resection then treatment with temozolomide chemotherapy.

Clinical TrialLevetiracetam monotherapy in patients with brain tumor-related epilepsy: seizure control, safety, and quality of life.
We performed a case series analysis to evaluate the effects of levetiracetam (LEV) monotherapy on seizures, adverse events, cognitive functioning and quality of life (QoL) in patients with brain tumor-related epilepsy (BTRE). We also explored the possible effects of systemic therapies on the efficacy of LEV. Twenty-nine patients were followed (13 female, 16 male; age 24-75 years) with 12 months of follow-up. ⋯ Our data suggest that seizure occurrence can be an important warning sign that the clinician should heed throughout the duration of the illness. Patients with BTRE represent a unique patient population that presents difficulties regarding management of two very different pathologies: epilepsy on the one hand, and brain tumor on the other. Our data indicate that LEV, in patients with BTRE, is safe and efficacious, with positive impact on QoL.

Radiotherapy and temozolomide for newly diagnosed glioblastoma and anaplastic astrocytoma: validation of Radiation Therapy Oncology Group-Recursive Partitioning Analysis in the IMRT and temozolomide era.
Since the development of the Radiation Therapy Oncology Group-Recursive Partitioning Analysis (RTOG-RPA) risk classes for high-grade glioma, radiation therapy in combination with temozolomide (TMZ) has become standard care. While this combination has improved survival, the prognosis remains poor in the majority of patients. Therefore, strong interest in high-grade gliomas from basic research to clinical trials persists. ⋯ For patients with newly-diagnosed high-grade gliomas, RTOG-RPA classes retained prognostic significance in patients treated with TMZ and IMRT. In contrast to RTOG-RPA, in our modified RPA model, KPS rather than age represented the initial split. New recursive partitioning identified potential modifications to RTOG-RPA that should be further explored with a larger data set.

Gamma Knife surgery (GKS) has emerged as a valuable adjuvant treatment modality for recurrent or residual craniopharyngioma. However, prognostic factors pertaining to progression-free survival (PFS) remain poorly understood. A study was conducted to address this issue. ⋯ On univariate analysis, absence of VFD at GKS was a favorable prognostic factor (hazard ratio: 0.279; 95% CI, 0.085-0.913, P = 0.035), whereas on multivariate analysis, absence of VFD at GKS, tumor volume ≤1.6 cm(3), and marginal dose >14.5 Gy related to a longer in-field PFS. GKS may offer reasonable control of recurrent or residual craniopharyngiomas. There was a consistent correlation between absence of VFD at the time of GKS and in-field PFS.
