Outcomes of systemic bevacizumab in radiation-induced optic neuropathy, case series
ConclusionSystemic bevacizumab may stabilize vision in some patients with RION, though the limitations of our study do not allow us to draw this conclusion definitively. Therefore, the risks and potential benefits of using IV bevacizumab should be considered in each individual case.

Transcranial magnetic stimulation for post-operative neurorehabilitation in neuro-oncology: a review of the literature and future directions
ConclusionsAlthough data are overall limited, both safety and effectiveness have been demonstrated for the use of rTMS for neurorehabilitation in the neuro-oncologic population. More randomized controlled trials and specific comparisons of contralateral versus ipsilateral rTMS protocols should be explored. Further work may also focus on individualized, patient-specific TMS treatment protocols for optimal functional recovery.

Relationship between 7T MR-angiography features of vascular injury and cognitive decline in young brain tumor patients treated with radiation therapy
ConclusionsArterial volume is reduced with increasing CMB presence and is influenced by the total brain volume exposed to radiation. This work highlights the potential use of vascular-derived metrics as non-invasive markers of treatment-induced injury and cognitive impairment in pediatric brain tumor patients.

Prophylactic anticoagulation in patients with glioblastoma or brain metastases and atrial fibrillation: an increased risk for intracranial hemorrhage?
ConclusionAC did not seem to influence the incidence of ICH in patients with glioblastoma or brain metastases within follow up of just under 9  months.

Stroke rate after external fractionated radiotherapy for benign meningioma
ConclusionOur study shows a higher incidence of stroke in patients who received radiotherapy for their benign meningioma compared to the general population.

Contrast enhancing spots as a new pattern of late onset pseudoprogression in glioma patients
ConclusionWe hypothesize that the late onset phenomenon of NCES predominantly represents a form of radiation-induced vasculopathy that is different from early pseudoprogression and should be considered especially in younger patients with IDH-mutated glioma before initiation of new therapy.

Platelet count is associated with outcome in cancer patients with stroke
ConclusionIn cancer patients with CVD, thrombocytopenia at the time of CVD diagnosis and altered mental status during initial clinical evaluation were associated with higher mortality, which should be confirmed in future studies.

Features of diffuse gliomas that are misdiagnosed on initial neuroimaging: a case control study
ConclusionSeveral clinical and radiologic metrics are associated with diffuse gliomas that are missed or misdiagnosed on the initial neuroimaging study. Knowledge of these associations may aid in avoiding misinterpretation and accurately diagnosing such cases in clinical practice.

Predictors of unknown cancer in patients with ischemic stroke
AbstractStroke is the second most frequent neurologic finding in postmortem studies of cancer patients. It has also been described as the first expression of an occult cancer. We have studied patients diagnosed with cancer after an ischemic stroke (IS) and we analyze differences with non-tumor patients. Single cohort longitudinal retrospective study of patients admitted to our center with IS diagnosis from 1 January 2012 to 12 December 2014. All patients were followed for 18  months. Patients with transient ischemic infarction or cerebral hemorrhage, active cancer or in the last 5 years, inability to follow-up or absence...

Ischemic stroke after radiation therapy for pituitary adenomas: a systematic review
In conclusion, complications of cerebral ischemia after radiotherapy for pituitary adenoma are infrequently reported. Moreover, after correction for several confounders, no significant difference in ischemic stroke rate between irradiated and non-irradiated patients could be identified.

Reduced-volume radiotherapy for patients with localized intracranial nongerminoma germ cell tumors
We examined outcomes of NGGCT patients receiving reduced-volume RT at a single institution. Records of 16 patients who received reduced-volume RT as part of definitive treatment between 1996 and 2016 were reviewed. Median age at presentation was 10.8 years (range 4.6 –41.0 years). Ten patients had pineal tumors and 6 had suprasellar tumors. All received chemotherapy and 9 patients received second-look surgery thereafter. RT volume was tumor-only to a median of 54 Gy (range 50.4–54 Gy) in 3 patients and whole-ventricle irradiation to a median of 30.6 Gy (r ange 30.6–36 Gy) with a boost to 54 Gy in 13 patients. Me...

Ischemic stroke and intracranial hemorrhage in patients with recurrent glioblastoma multiforme, treated with bevacizumab
AbstractBevacizumab (BVZ), a monoclonal antibody directed against vascular endothelial growth factor (VEGF), has been suspected to increase the incidence of ischemic stroke (IS) and intracranial hemorrhage (ICH) in GBM patients. Intracranial vascular events, such as IS and ICH, were retrospectively analyzed in 364 MRI scans of 82 patients with recurrent GBM (1st/2nd/3rd relapse). Out of these 82 patients, 40 were treated with BVZ (178 scans) in addition to basic treatment, whereas 42 patients matching for age and gender received basic treatment (186 scans). Distribution of typical vascular risk factors between both groups ...

Therapeutic dormancy to delay postsurgical glioma recurrence: the past, present and promise of focal hypothermia
AbstractSurgery precedes both radiotherapy and chemotherapy as the first-line therapy for glioma. However, despite multimodal treatment, most glioma patients die from local recurrence in the resection margin. Glioma surgery is inherently lesional, and the response of brain tissue to surgery includes hemostasis, angiogenesis, reactive gliosis and inflammation. Unfortunately, these processes are also associated with tumorigenic side-effects. An increasing amount of evidence indicates that the response to a surgery-related brain injury is hijacked by residual glioma cells and participates in the local regeneration of tumor ti...

Treatment of pediatric cerebral radiation necrosis: a systematic review
Abstract Cerebral radiation necrosis (CRN) is a toxicity of radiation therapy that can result in significant, potentially life-threatening neurologic deficits. Treatment for CRN has included surgical resection, corticosteroids, hyperbaric oxygen therapy (HBOT), and bevacizumab, but no consensus approach has been identified. We reviewed the available literature to evaluate efficacy of treatment approaches. Using methods specified in the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines when possible, we conducted searches of Ovid MEDLINE, Embase and Pubmed to identify studies re...
