Image-derived Prediction of Response to Chemo-radiation in Glioblastoma
This study seeks to investigate if advanced image-analysis of diagnostic scans, can be used to predict how aggressive brain tumors (glioblastoma) respond to standard chemo- and radiation treatment.

Image Guided Reirradiation of High-grade Glioma
The purpose of the study is to evaluate the short- and long term toxicity of radiotherapy to patients with recurrent high-grade glioma who have previously received radiotherapy and to determine the best dose and treatment regimen. Positron emission tomography (PET) using an amino acid tracer, 18-fluoro-ethyltyrosine (18F-FET), is used for target delineation.The study examines, in four sequential treatment groups, the effect of dose, hypofractionation and treatment volume on toxicity. Upon completion of the phase I part, the study progresses to phase II where the best dose- and treatment regimen will be chosen for treatment.

Imaging Study of Glioblastomas Treated With Avastin
This study aims to assess the effect of Avastin on brain vascularity and blood-brain permeability using dynamic contrast ct scans (DECT) and MRI imaging. Previous publications have documented the method by which DECT can determine alterations in vascular volume and tissue permeability within tumors and normal brain tissue. Functional maps of cerebral blood flow cerebral blood volume and permeability-surface area can be generated from the DECT studies to assess tumor perfusion. MRI spectroscopy analyzes brain chemistry to detect tumour versus edema versus normal brain. Thirty patients will receive MRI spectroscopy and DECT imaging at the time of presumed recurrence and 3...

Imaging Trial With I-124-CLR1404 in Patients With Newly Diagnosed or Recurrent Glioblastoma
The primary objective of this trial is to determine the optimal dose and imaging time point(s) of I-124-CLR1404 in subjects with newly diagnosed and recurrent glioma to be used in future trials.

Imatinib Mesylate With or Without Radiation Therapy in Treating Young Patients With Newly Diagnosed or Recurrent Glioma
Phase I/II trial to estimate the maximum tolerated dose of imatinib mesylate in newly diagnosed brain stem gliomas and recurrent high grade gliomas and to assess the effectiveness of imatinib mesylate in treating young patients who have newly diagnosed intrinsic brain stem glioma. Imatinib mesylate may interfere with the growth of tumor cells by blocking the enzymes necessary for their growth. Radiation therapy uses high-energy x-rays to damage tumor cells. Combining imatinib mesylate with radiation therapy may kill more tumor cells.

Imetelstat Sodium in Treating Younger Patients With Recurrent or Refractory Brain Tumors
This molecular biology and phase II trial studies how well imetelstat sodium works in treating younger patients with recurrent or refractory brain tumors. Imetelstat sodium may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth.

Imiquimod/Brain Tumor Initiating Cell (BTIC) Vaccine in Brain Stem Glioma
This is a pilot/feasibility study. The study design represents a modification of current standard of care for Diffuse Intrinsic Pontine Glioma (DIPG) (5580 cGY involved field radiation), with the final two doses of radiation given at intervals during the vaccination phase of treatment. Patients between the ages of 3 years and 25 years diagnosed with Diffuse Intrinsic Pontine Glioma (DIPG) will be allowed to participate in the trial. Study enrollment will occur after the completion of conformal radiation therapy to a dose of 5580 cGy and the post radiation therapy (RT) magnetic resonance imaging (MRI) shows no disease progression. Three patients with glioblastoma multiforme,...

Immunotherapy Targeted Against Cytomegalovirus in Patients With Newly-Diagnosed WHO Grade IV Unmethylated Glioma
This single-arm phase II study will assess the impact of tetanus pre-conditioning and adjuvant Granulocyte Macrophage Colony Stimulating Factor (GM-CSF) on overall survival of patients newly diagnosed with World Health Organization (WHO) Grade IV glioblastoma who have undergone definitive tumor resection, are cytomegalovirus (CMV) positive and unmethylated, and completed standard temozolomide (TMZ) and radiation treatment. After completion of the standard of care radiotherapy with concurrent TMZ, patients will receive 1 cycle of dose-intensified TMZ followed by pp65-loaded dendritic cell (DC) vaccination beginning on day 23.

Immunotherapy With Autologous Tumor Lysate-Loaded Dendritic Cells In Patients With Recurrence Of Glioblastoma Multiforme
Rationale of the Study: Treatment for GBM currently consists of surgical resection of the tumour mass followed by radio- and chemotherapy. Nonetheless overall prognosis still remains bleak, recurrence is universal, and recurrent GBM patients clearly need innovative therapies. Dendritic cells (DC) immunotherapy could represent a well-tolerated, long-term tumour-specific treatment to kill all (residual) tumour cells which infiltrate in the adjacent areas of the brain. Preclinical investigations for the development of therapeutic vaccines against high grade gliomas, based on the use of DC loaded with a mixture of glioma-derived tumor have been carried out in rat as well as in mouse...

Improving Ultrasound Images in Brain Tumour Surgery With the Use of an Acoustic Coupling Fluid Mimicking Brain Tissue.
Tools for improving brain tumor surgery, in particular for gliomas, are increasing. There seems to be an agreement that achieving extensive resections, when done safely without jeopardizing neurological function, improves survival. Ultrasound is currently used as a tool for providing 2D or 3D images for tumor localization and resection control. For the use in resection control the resection cavity is filled with saline to provide acoustic coupling between the ultrasound transducer and tissue. However, attenuation of acoustic waves is very low in saline compared to the brain and this difference in attenuation is the cause of artifacts that may severely degrade the ultrasound...
