Ischemic stroke in patients with gliomas at The University of Texas-M.D. Anderson Cancer Center
Abstract Patients with gliomas are at risk of cerebrovascular accidents (CVA) with potential consequences on survival, function, and local tumor control. Our objective was to provide information about CVA in patients with gliomas and to estimate survival in this group. We reviewed all adult glioma patients with ischemic CVA at the University of Texas-M.D. Anderson Cancer Center from 2003 through 2014. We extracted demographic, clinical, imaging, treatment and outcome data. We used descriptive summary data and estimated or compared survival rates where appropriate. 60 of 6500 patients (0.1 %) with high-grade (HGG,...

Cn-14 * retrospective analysis of ischemic cerebral strokes in patients diagnosed with a glioblastoma during the course of a bevacizumab treatment
Bevacizumab is an anti-vascular endothelial growth factor approved in the treatment of recurrent glioblastoma. It prolongs progression-free survival, improes radiologic response and contributes to reduce the dose of dexamethasone required to control peritumoral edema. Arterial and venous thromboembolic events represent significant toxicities related to the use of angiogenesis inhibitors. Various mechanisms could be implicated in bevacizumab-related strokes, as cardioembolic, lacunar stroke related to hypertension, deep venous thrombosis passing through a patent foramen ovale, pro-coagulant effect of the underlying glioblas...

Vascular complications in glioma patients.
Abstract Vascular complications in patients with glioma most commonly include venous and arterial thromboembolism; however, treatment-induced vasculopathies are also problematic, especially in long-term survivors. The interactions between treatment such as radiation and chemotherapy, the coagulation cascade, endothelium, and regulators of angiogenesis are complex, drive glioma growth and invasion, and create common management problems in the clinic. We review the incidence of thrombotic complications in glioma, the biology of the coagulome as related to glioma progression, prevention and treatment of thrombosis, t...

Ntox-08. safety of intra-arterial chemotherapy in the treatment of brain tumours
The treatment of brain tumors is greatly limited the delivery impediment caused by the blood-brain barrier and blood-tumor barrier. To circumvent this limitation, different approaches have been studied, including intra-arterial delivery. Because of a significant local increase in plasma-peak concentration, this strategy increases the local area under the curve, and translates into a 3 to 5.5 fold increase in intra-tumoral chemotherapy concentration. However, intra-arterial chemotherapy in the treatment of brain tumors has a notoriously bad name, thanks to prior trials led in past decades showing significant neurotoxicities...

Surg-38. direct evidence of plasticity within primary motor and sensory cortices via direct electrical stimulation in glioblastoma patients undergoing repeat awake craniotomy
In this study, we examine plasticity within primary sensory (S1) and motor (M1) cortices in glioblastoma patients undergoing repeat intra-operative direct electrical stimulation (DES) under awake conditions.METHODS:This retrospective analysis included five patients with glioblastoma in/near M1/S1 that underwent two awake surgeries, each with DES-based sensory and motor mapping. Inter-surgery interval was 216 ± 41 days. Plasticity was defined as a change in mapping result (gain, loss, or change of function) within M1/S1 at second operation or absence of typical mapping result without a change in the patient&rsqu...

Rt-08 * proton therapy (pt) large-volume re-irradiation for recurrent glioma: overall survival (os) and toxicity outcomes
CONCLUSION: Large-volume PT re-irradiation for recurrent glioma is safe and associated with promising OS outcomes, particularly in the setting of bevacizumab-refractory tumors.

Abstract 4058: Acid-sensing ion channel 1a (ASIC1a) contributes to cell proliferation and migration caused by acidic environment in human glioma cells
Conclusions: Extracellular acid reduces proliferation and migration in glioma cells. Extracellular acid induces death of glioma cells via ASIC1a mechanisms. These results indicate the presence of ASIC1a in glioma cells and may play significant role in glioma progression.

Study points to possible treatment for lethal pediatric brain cancer
(NIH/National Institute of Neurological Disorders and Stroke) Using brain tumor samples collected from children in the United States and Europe, an international team of scientists found that the drug panobinostat and similar gene regulating drugs may be effective at treating diffuse intrinsic pontine gliomas, an aggressive and lethal form of pediatric cancer.

Calcification in high grade gliomas treated with bevacizumab
Abstract Calcification is a rare phenomenon in high grade glioma (HGG). CT scans are sensitive to mineralization but used infrequently for tumor assessment in the MRI era. The presence of calcification can be overlooked on routine MRI. Calcification may reflect chronicity and natural changes in the tumor or its milieu over time and may be accelerated by certain treatments. Calcification may have clinical significance which could signal potential risk for stroke or hemorrhage related to particular therapies; or it may be a positive prognostic factor for treatment response. The true incidence and relevance of calcif...

OS5.8 Intravascular lymphoma affecting the central nervous system: features and outcomes in a case series of the Primary CNS Lymphoma Collaborative Group (IPCG)
We present a retrospective case series of 65 adults with IVL from 14 cancer centers in 6 countries. IVL was restricted to the CNS in 29 cases, with a mean age of 60 years and 91% of patients having neurological deficits at the time of diagnosis. There was a mean diagnostic delay of 20 weeks after presentation of stroke-like symptoms or myelopathy. Ninety-three percent had a poor functional status with an Eastern Cooperative Oncology Group (ECOG) performance status ≥2. Serum LDH was elevated in 87% of patients with no correlation with treatment outcome. Frontline treatment with intravenous high-dose methotrexate-bas...

P08.46 Rechallenge with bevacizumab in a long-term survivor with glioblastoma
The prognosis of patients with glioblastoma multiforme (GBM, WHO grade IV), the most common primary brain tumor in adults, is generally poor with median survival of less than one year in untreated patients and approximately 15 months following standard of care therapy. However, 10 % survival at 5 years was observed in a randomized phase III study. At GBM recurrence, the addition of bevacizumab (BEV), a humanized monoclonal antibody against circulating vascular endothelial growth factor (VEGF), resulted in a 3–4 month prolongation of progression-free survival (PFS) without improving overall survival (OS...
