OBJECTIVES: The purpose of this study was to evaluate the prognostic relevance of temporal muscle thickness (TMT) in melanoma patients with newly diagnosed brain metastases. METHODS: TMT was retrospectively assessed in 146 melanoma patients with newly diagnosed brain metastases on cranial magnetic resonance images. Chart review was used to retrieve clinical parameters, including disease-specific graded prognostic assessment (DS-GPA) and survival times. RESULTS: Patients with a TMT > median showed a statistically significant increase in survival time (13 months) compared to patients with a TMT < median (5 months; p < 0...

Gliomatosis cerebri (GC) is an aggressive glioma characterized by an invasive growth pattern and a dismal prognosis. The low incidence and non-specific symptoms at presentation pose unique challenges for early diagnosis and disease-specific research. There is no standard of care for the treatment of patients with a GC phenotype. Understanding the biology of this entity is a critical step in determining effective treatments. Toward this end, the Second International GC Group convened at National Institutes of Health, Bethesda on June 22nd-23rd 2017...

Nucleolar and spindle-associated protein (NUSAP1) is a microtubule and chromatin-binding protein that stabilizes microtubules to prevent depolymerization, maintains spindle integrity. NUSAP1 could cross-link spindles into aster-like structures, networks and fibers. It has also been found to play roles in progression of several cancers. However, the potential correlation between NUSAP1 and clinical outcome in patients with glioblastoma multiforme (GBM) remains largely unknown. In the current study, we demonstrated that NUSAP1 was significantly up-regulated in GBM tissues compared with adult non-tumor brain tissues both in a validated cohort and a TCGA cohort...

INTRODUCTION: Pineal region glioblastomas (GBM) are very rare, with approximately 46 cases described in the literature. The epidemiology, pathogenesis, and treatment of these lesions are poorly characterized. METHODS: We identified all cases of pineal region GBM treated surgically at our institution between 1990 and 2017. Demographic and clinical follow-up data were extracted from the medical records for all cases. Pathology was reviewed and classified according to 2016 World Health Organization (WHO) criteria...

BACKGROUND: Tumor treating fields (TTF) harness magnetic fields to induce apoptosis in targeted regions. A 2015 landmark randomized phase III trial of newly diagnosed glioblastoma (GBM) patients demonstrated TTF + temozolomide to be superior to temozolomide alone. Given these results, we sought to assess practice patterns of providers in TTF utilization for GBM. METHODS: A survey was administered to practices in the United States self-identifying as specializing in radiation oncology, medical oncology, neuro-oncology, neurosurgery, and/or neurology...

PURPOSE: To date, little is known about neuropsychiatric symptoms in patients with tumors within the cerebellopontine angle (CPA). These, however, might be of clinical relevance. Aim of this study was thus to assess possible impairment in cognition, elevation in mood symptoms, and fatigue in this specific patient group. METHODS: Forty-five patients with an untreated CPA tumor (27 vestibularis schwannoma, 18 meningioma) were tested within a cross-sectional observational study in a single institution prior to neurosurgical treatment...

INTRODUCTION: The current study aimed to assess whether childhood-onset craniopharyngioma patients suffer from symptoms of apathy, as assessed by patients themselves and their close others. We further analyzed whether apathy scores are related to symptoms of depression. METHODS: Childhood-onset craniopharyngioma patients (n = 35, 16 female, median age = 22) and matched healthy controls (n = 35, 19 female, median age = 21) were asked to complete self-ratings of the Apathy Evaluation Scale, whereas informant-ratings were obtained from their close others...

PURPOSE: Spinal meningiomas are slow-growing intradural-extramedullary tumors. They are usually associated with good outcomes. However, there are few descriptions of factors predictive of impaired evolution. Our objective was to identify predictive factors of post-operative deterioration as well as outcomes at follow-up. METHODS: Between 2009 and 2016, 87 patients had surgery for spinal meningioma in our referral center. Clinical presentation, management and outcomes were reported during the post-operative period and at 3-month follow-up...
