Detecting Malignant Brain Tumor Cells in the Bloodstream During Surgery to Remove the Tumor
Glioblastomas, the most frequent malignant brain tumor in adults, are widespread in the brain, despite their discrete appearance on computed tomography (CT) or magnetic resonance imaging (MRI). While this tumor tends to spread widely in the brain, unlike other tumors of the body, it rarely metastasizes, or spreads, to other organs. Approximately 10 percent of patients with glioblastoma develop metastatic disease after radiation or brain surgery. In the absence of radiation or brain surgery, few patients have developed disease spread outside the brain. During surgery to remove tumors of other organs of the body, such as the lung, prostate, kidney, or ovary, cells from these...

Determination of Immune Phenotype in Glioblastoma Patients
Glioblastoma multiforme (GBM) is the most common primary brain tumor in adults. Despite intensive research efforts and a multimodal management that actually consists of surgery, radiotherapy and chemotherapy with temozolomide, the prognosis is dismal. The aim of the current observational study is to determine immune phenotypes in individual patients with GBM at the time of diagnosis and to correlate tumor size, location (imaging), tumor properties (isocitrate dehydrogenase - 1 (IDH-1), o6-methylguanine-DNA-methyltransferase (MGMT), epidermal growth factor receptor (EGFR) mutation status, etc.) with clinical data, such as progression free and overall survival, Karnofsky index...

Development of Strategies to Increase Enrollment in Clinical Trials for Children With Cancer
RATIONALE: Taking part in a clinical trial may help children with cancer receive more effective treatment. PURPOSE: Determine why patients who are eligible for protocols made available through the Pediatric Oncology Group do not enroll in them, and develop strategies to increase enrollment on these clinical trials.

Dexanabinol in Patients With Brain Cancer
The purpose of this study is to try to determine the maximum safe dose of dexanabinol that can be administered to people with brain cancer. Other purposes of this study are to: - find out what effects (good and bad) dexanabinol has; - see how much drug gets into the body by collecting blood and cerebrospinal fluid for use in pharmacokinetic (PK) studies; - learn more about how dexanabinol might affect the growth of cancer cells; - look at biomarkers (biochemical features that can be used to measure the progress of disease or the effects of a drug).

Diffusion Tensor MRI to Distinguish Brain Tumor Recurrence From Radiation Necrosis
This study will examine the use of a variation of standard magnetic resonance imaging (MRI) called diffusion tensor MRI (DT-MRI) for distinguishing injured brain tissue due to radiation therapy (radiation necrosis) from the return of a brain tumor that was previously removed (tumor recurrence). DT-MRI differs from standard MRI in the way that computers process the images; there is no difference in the experience of having the procedure done. Both radiation necrosis and tumor recurrence can occur within weeks to months following brain radiation treatment. Because the treatment and management options for the two conditions differ significantly, distinguishing the two is of...

Dimethyl Fumarate, Temozolomide, and Radiation Therapy in Treating Patients With Newly Diagnosed Glioblastoma Multiforme
This phase 1 trial studies the side effects and best dose of dimethyl fumarate when given together with temozolomide and radiation therapy(RT) in treating patients with newly diagnosed glioblastoma multiforme (GBM). Dimethyl fumarate may help radiation therapy work better by making tumor cells more sensitive to the radiation therapy. Drugs used in chemotherapy, such as temozolomide, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Radiation therapy uses high energy x-rays to kill tumor cells and shrink tumors. Giving dimethyl fumarate with temozolomide and radiation therapy may...

Disulfiram/Copper With Concurrent Radiation Therapy and Temozolomide in Patients With Newly Diagnosed Glioblastoma
The proposed phase I/II study of disulfiram (DSF) for patients with presumed glioblastoma multiforme (GBM) based on magnetic resonance imaging (MRI) or biopsy, including administration before surgery and during adjuvant chemoradiotherapy. Patients will be treated with 3 days of preoperative DSF/copper (Cu) prior to their surgery (or biopsy), which will be followed by collection of tumor samples during surgery for analysis of drug uptake. After the surgery, patients will receive standard radiation therapy (RT) and temozolomide (TMZ) with the addition of concurrent DSF/Cu.

Disulfiram in Recurrent Glioblastoma
Disulfiram (Antabuse®) is a well-tolerated, cheap, generic drug that has been in use since the 1950s to treat alcoholism. There is now an increasing amount of independent preclinical data to support disulfiram as an anticancer agent. The potency of disulfiram as an anticancer agent seems strengthened by copper. The investigators aim is to investigate disulfiram and copper-supplement as add-on treatment in glioblastoma patients with recurrence receiving alkylating chemotherapy.

Disulfiram in Treating Patients With Glioblastoma Multiforme After Radiation Therapy With Temozolomide
This clinical trial studies disulfiram in treating patients with glioblastoma multiforme (GBM) who have completed radiation therapy with temozolomide. Disulfiram may block some of the enzymes needed for tumor cell growth and improve clinical outcome in GBM patients.
