Objective To evaluate the role of minimum apparent diffusion coefficient(MinADC) values in peritumoral edema based on magnetic resonance diffusion weighted imaging in the differential diagnosis between primary central nervous system lymphoma(PCNSL) and glioblastoma(GBM).Methods ADC values in
The aim of this systematic review was to examine the relationship between pre-operative peritumoral edema and survival in patients with glioblastoma multiforme (GBM). We searched for studies involving patients with GBM who underwent pre-operative imaging (magnetic resonance imaging and/or computed
BACKGROUND
Peritumoral brain edema in glioblastoma patients is a frequently encountered phenomenon that strongly contributes to neurological signs and symptoms. The role of peritumoral edema as a prognostic factor is controversial.
METHODS
This multi-centre clinical retrospective study included 110
Irradiating glioblastoma preoperative edema (PE) remains controversial. We investigated the associations between tumors' PE extent with invasion into synchronous subventricular zone and corpus callosum (sSVZCC) and treatment outcomes to provide the clinical evidence for radiotherapy
Nivolumab is an immune checkpoint inhibitor (ICI) currently undergoing Phase III clinical trials for the treatment of glioblastoma. The authors present the case of a 10-year-old girl with glioblastoma treated with nivolumab under compassionate-use guidelines. After the first dose of nivolumab the
Glioblastoma (GB) is one of the most common adult primary brain tumors, classified as a grade IV astrocytoma and highly malignant in nature. As the tumor grows and disrupts the blood-brain barrier (BBB), vasogenic edema can result. The edema has the potential to significantly contribute to a
Glioblastoma patients often require chronic administration of steroids due to peri-tumoral edema. Preliminary studies showed that treatment with Angiotensin-II Receptor Blockers (ARBs) for high blood pressure might be associated with reduced peri-tumoral edema. In this study, we aim to
In the article authors consider reasons, leading to the formation of edema around the glioblastoma by analysis of perifocal edema size, glioblastoma size and necrosis zone correlation. According their data, the size of glioblastoma edema, revealed by MRI, varies widely. Practically, in third of
It is well recognized that peritumoral edema is vasogenic cerebral edema in malignant glioma, and vascular endothelial growth factor (VEGF) induced by phosphorylated signal transducer and activator of transcription factor 3 (pSTAT3) strongly contributes to tumor angiogenesis in glioblastoma.
OBJECTIVE
To investigate the expression of aquaporin-4 (AQP4) in the brains of patients with glioblastoma and its association with brain edema.
METHODS
Immunofluorescence cytochemistry and western blot tests were performed to detect the expression of AQP4 in the brain tumors and the adjacent tissues
OBJECTIVE
Glioblastoma and solitary metastatic lesions can be difficult to differentiate with conventional MRI. The use of diffusion-weighted MRI to better characterize peritumoral edema has been explored for this purpose, but the results have been conflicting. The purpose of this study was to test
OBJECTIVE
Anti-edema effect of bevacizumab was evaluated using the apparent diffusion coefficient (ADC) of peritumoral edema associated with regional cerebral blood flow (rCBV) of the tumor.
METHODS
Nine patients with recurrent glioblastoma were treated using bevacizumab for 4 ∼ 36 months (average
BACKGROUND
Neovascularization and peritumoral edema are hallmarks of glioblastoma (GBM). Programmed cell death 10 (PDCD10) plays a pivotal role in regulating apoptosis, neoangiogenesis and vessel permeability and is implicated in certain tumor signaling pathways. However, little is known about
Keeping in mind that the expression of vascular permeability factor (VPF) in astrocytic tumors has been related to tumor angiogenesis and peritumoral edema (PE), the aim of this study is to investigate the correlation between degree of VPF expression by tumor cells, and degree of PE and vascular
Delta-like ligand 4 (DLL4), 1 of the 5 known Notch ligands, is involved in a variety of tumor initiation and progression, particularly in the process of tumor angiogenesis. However, the clinical and prognostic significance of DLL4 in glioblastoma have not been fully elucidated.Tumor tissues from 69
