A Comparison of FDG-PET Versus MRI Based Target Volume Delineation in Glioblastoma and the Role of FDG-PET/CT in the Alteration of MRI Based Target Volumes.
HYPOTHESIS AND SAMPLE SIZE The tumor delineated by FDG-PET is significantly different from the delineation achieved by MR T1 contrast weighted images in glioblastoma; expecting a standard error of 12.5 % (a confidence interval of 25%), with a confidence level set at 95%, a sample size of 15 patients would be accrued in the study.

Medical and Biotech [MESH] Definitions
Benign and malignant central nervous system neoplasms derived from glial cells (i.e., astrocytes, oligodendrocytes, and ependymocytes). Astrocytes may give rise to astrocytomas (ASTROCYTOMA) or glioblastoma multiforme (see GLIOBLASTOMA). Oligodendrocytes give rise to oligodendrogliomas (OLIGODENDROGLIOMA) and ependymocytes may undergo transformation to become EPENDYMOMA; CHOROID PLEXUS NEOPLASMS; or colloid cysts of the third ventricle. (From Escourolle et al., Manual of Basic Neuropathology, 2nd ed, p21)
A malignant form of astrocytoma histologically characterized by pleomorphism of cells, nuclear atypia, microhemorrhage, and necrosis. They may arise in any region of the central nervous system, with a predilection for the cerebral hemispheres, basal ganglia, and commissural pathways. Clinical presentation most frequently occurs in the fifth or sixth decade of life with focal neurologic signs or seizures.
Transforming Growth Factor Beta2
A TGF-beta subtype that was originally identified as a GLIOBLASTOMA-derived factor which inhibits the antigen-dependent growth of both helper and CYTOTOXIC T LYMPHOCYTES. It is synthesized as a precursor molecule that is cleaved to form mature TGF-beta2 and TGF-beta2 latency-associated peptide. The association of the cleavage products results in the formation a latent protein which must be activated to bind its receptor.
Intracranial tumors originating in the region of the brain inferior to the tentorium cerebelli, which contains the cerebellum, fourth ventricle, cerebellopontine angle, brain stem, and related structures. Primary tumors of this region are more frequent in children, and may present with ATAXIA; CRANIAL NERVE DISEASES; vomiting; HEADACHE; HYDROCEPHALUS; or other signs of neurologic dysfunction. Relatively frequent histologic subtypes include TERATOMA; MEDULLOBLASTOMA; GLIOBLASTOMA; ASTROCYTOMA; EPENDYMOMA; CRANIOPHARYNGIOMA; and choroid plexus papilloma (PAPILLOMA, CHOROID PLEXUS).
The purpose of this study is to determine whether the immunostimulating agent CpG-ODN is effective in the treatment of glioblastoma
The aim of this study is to establish FET-PET as an additional therapy assessment parameter in patients diagnosed with a glioblastoma multiforme receiving radiochemotherapy and adjuvant ch...
A single arm Phase 2 trial with the study drug temozolomide (temodar) for newly diagnosed glioblastoma in elderly patients (defined as greater than or equal to 70 years old). Following sur...
This protocol will test the activity of Enzastaurin vs. Lomustine in the treatment of recurrent brain cancer (specifically intracranial glioblastoma multiforme).
The objective of this study is to assess the efficacy and safety of TLN-4601 used to treat patients with Glioblastoma Multiforme(GBM) that recur/progress after receiving first line systemi...
Glioblastoma is the most common type of astrocytoma in the brain. Due to its high invasiveness and chemoresistance, patients with advanced stage of glioblastoma have a poor prognosis. SNAI1, an import...
microRNA-124 (miR-124) plays an important role in regulating growth, invasiveness, stem-like traits, differentiation and apoptosis of glioblastoma cells. PPP1R3L, an inhibitory member of the apoptosis...
Invasion of glioblastoma cells significantly reduces the effectiveness of current treatments, highlighting the importance of understanding dispersal mechanisms and characteristics of the invasive popu...
ABSTRACT: Regulatory T cells, Tregs, are a subset of lymphocytes that have immunosuppressive attributes. They are elevated in blood of glioblastoma patients and within this tumor's tissue itself. Indo...
Glioblastoma is a disease with poor outcomes despite standard therapy. Specific targeting of the DNA damage response is a strategy that is becoming increasingly employed in oncology and has intriguing...
