Background Glioblastoma (GBM) is the most common and devastating malignant brain tumor in adults. Patients with glioblastoma face a poor prognosis. Despite maximal treatment, most patients suffer tumor progression after 6-7 months and die within 1-2 years. Standard treatment for newly diagnosed
Primary central nervous system lymphomas (PCNSL) are extra-nodal, malignant non-Hodgkin lymphomas of diffuse large B-cell type confined to the CNS or eyes without evidence of systemic spread. PCNSL account for up to 1% of all lymphomas and 3% of primary brain tumors. Despite recent progress in PCNSL
Brain tumors are the first cause of cancer mortality in children and the 3rd cause in young adults. The most frequent brain tumors are gliomas and among them the most common type is astrocytoma. The most malignant astrocytoma is Glioblastoma (GBM). Standard therapy of newly diagnosed GBM patients
Primary brain tumors in adults are less common than metastatic tumors. The most frequent are glioblastoma multiforme, metastases, anaplastic astrocytoma, meningioma, pituitary tumors and vestibular schwannoma. 70% of the tumors in adults are supratentorial. The most infratentorial tumors are
New approaches are needed for patients newly diagnosed with bulky glioblastoma (GB) and/or with severe neurological impairment that cannot benefit from first line temozolomide (TMZ)-based chemoradiotherapy. Bevacizumab (BEV), an antiangiogenic anti-VEGF-R monoclonal antibody, has a rapid impact on
This is a multicenter observational retrospective study with data collected from Hospital Information System (HIS) and Picture Archiving and Communication System (PACS) of each center involved in the study. The cohort is built with patients diagnosed with glioblastoma (GBM) with a Magnetic Resonance
High-grade gliomas of the central nervous system (CNS) are characterized by profound tumor related neo-angiogenesis, and intracranial perilesional edema. Glioblastoma (WHO-grade IV glioma) expresses high levels of VEGF and frequently carries an amplified gene copy numbers of the VEGFR2, KIT and
BACKGROUND Radiation Necrosis: Stereotactic radiosurgery has become integral in treatment of brain tumors and arteriovenous malformations (AVM). In up to 10% of cases, this can lead to radiation necrosis (RN) with significant surrounding vasogenic edema and mass effect. Medical treatment for RN
Human oncologic tissues exhibit strong phenotypic differences. Due to advances in both acquisition and analysis methods of medical imaging technologies, the extraction of reliable and informative image features to quantify these differences is currently possible. Radiomics, the extraction of large
Glioblastoma (GBM) is the most common primary malignant brain tumor. Despite great efforts have been devoted to promoting the treatment effect, GBM remains one of the most lethal tumors concurrent with poor prognosis and inevitable recurrence. The standard treatment protocol for GBM includes
Glioblastoma (GBM), the most common and most malignant primary brain tumor, represents a major medical challenge considering its extremely poor prognosis (Wen 2008). Current standard of care includes maximal surgical resection, followed by concomitant radio-chemotherapy (temozolomide - TMZ) (RT-CT)
1.1 Primary Aim: To describe MRI response rate as regards edema and enhancement of glioblastoma and radiation- related brain enhancement when treated with subcutaneous (SQ) bevacizumab daily. See section 11 for detail on response assessment.
1.2 Secondary Aims: 1.2.1 To characterize toxicities of SQ
20 patients with newly diagnosed histopathologically confirmed glioblastoma (WHO Grade IV) after surgery will be enrolled in the study. All of the patients will receive conventional concurrent chemoradiation and adjuvant temozolomide plus bevacizumab begin > 3 weeks and ≤ 5 weeks after surgery.
Malignant gliomas are the most common type of brain tumor in adults. They are the second leading cause of cancer mortality in people under the age of 35 and the fourth leading cause in those under the age of 54. Standard therapy for glioblastoma multiforme (GBM) includes surgery followed by
