Adult classical glioblastoma with a BRAF V600E mutation

We report here the detection of the BRAF V600E mutation in a patient with c-GBM and describe the patient’s clinical course as well as the results of histopathological analysis.

Fleming, Forough Farrokhyar, Saleh Almenawer, Sheila K. Singh, Blake YarascavitchAbstractPurposeThe present study aims to determine the tumor-related, clinical, and demographic factors associated with extent of resection (EOR) and post-operative outcomes in JPA patients.MethodsAll patients with JPA, identified from a single-center brain tumour data base, were included in this retrospective analysis. Pre-operative MRI scans were reviewed by a single neurosurgeon ...

AbstractObjective5-Aminolevulinic acid (5-ALA) –guided resection of gliomas in adults enables better delineation between tumor and normal brain, allowing improved resection and improved patients’ outcome. Recently, several reports were published regarding 5-ALA for resection of pediatric brain tumors. The aim of the study was to determine th e intracellular fluorescence of protoporphyrin IX (PPIX) in pediatric brain tumors by hyperspectral imaging and to compare it with visually observed intraoperative fluorescence.Methods5-ALA was administered orally 4  h prior to surgery. During tumor resection, the surg...

We present three cases of NF1 patients referred for 18F-fluorocholine PET/CT because of suspected glioma in the setting of ongoing FUMEGA (Functional and Metabolic Glioma Analysis) trial. One case turned out to be a WHO grade I ganglioglioma; the second was a high grade glioma; and the last one (negative in PET) a probable low-grade glioma.

CONCLUSIONS: The authors' results show that surgical smoke from various brain tumors has distinct DMS profiles and the DMS analyzer connected to a special sampling system can differentiate between tumorous and nontumorous tissue and also between different tumor types ex vivo.

Background: Amphiregulin (AREG) is one of the ligands of the epidermal growth factor receptor which levels was shown to have a tight coherence with various types of cancer. AREG was also designated to be a promising marker for several types of cancer however precious little data about AREG role in the most frequent and generally lethal human brain tumours - astrocytomas reported up to date. The aim of the study was to investigate how AREG changes at epigenetic and expression levels reflect on astrocytoma malignancy and patient outcome.Methods: In total 205 low and high grade astrocytoma samples (15 pilocytic astrocytomas, ...

Conclusion: This preliminary study suggests that 64CuCl2 is accumulating in some but not all high-grade brain tumors. There appears to variability in the grade of Copper uptake in all grades of tumors. More data is being accumulated to define the cutoff of copper uptake as potential differentiating features for identifying possible theragnostic targets.

156Objectives: Brain tumors are the most common solid tumor in children and are responsible for substantial morbidity and mortality in the pediatric population. [18F] FDG PET/CT has been of limited utility in the evaluation of brain tumors, due to the high level of FDG uptake in the normal brain. Other PET radiopharmaceuticals, such as [18F] FLT, a putative measure of cellular proliferation, have demonstrated promise for the evaluation of brain tumors in adults, but have not been studied systematically in children. The aim of this study is to evaluate the use of [18F] FLT to assess cellular proliferation in pediatric brain...

Authors: Niranjan A, Faramand A, Lunsford LD Abstract Low-grade gliomas represent a heterogeneous group of tumors. The goals of treatment include prolonged survival and reduced morbidity. Treatment strategies vary depending upon tumor histology, anatomic location, age, and the general medical condition of the patient. Safe surgical resection remains the first choice for the treatment of resectable tumors. In cases of unresectable lesions, adjuvant radiotherapy and chemotherapy are considered. Several reports in recent years have documented the safety and effectiveness of stereotactic radiosurgery (SRS) in controlli...

KraussAbstractOccurrence of gliomas in patients with chronic deep brain stimulation (DBS) has been reported few. It has been speculated whether there could be a causal relationship. Here, we report the development of a pilocytic astrocytoma in close vicinity of a DBS electrode during the course of chronic DBS. A 38-year-old man with refractory dystonic head tremor underwent bilateral implantation of quadripolar DBS electrodes in the t...
