Filter by:The goal of this research study is to investigate the role of genes that may point to a higher risk of developing a glioma. Researchers will use new gene mapping techniques to study how high-risk factors are passed on through a family's genes and increase the risk of developing gliomas. Objectives: We propose an international multi-center, multidisciplinary study consortium, GLIOGENE, to identify susceptibility genes in high-risk familial brain tumor pedigrees using the most sophisticated genetic analysis methods available. To address our hypothesis, we propose the following specific aims: Aim 1: Establish a cohort of 400 high-risk pedigrees for genetic linkage analysis. To date, we have identified and collected biologic samples from 20 high-risk families that have met our criteria of 2 or more relatives diagnosed with a brain tumor. From the 15 centers in the United States and Europe, we will screen and obtain epidemiologic data from approximately 17,080 gliomas cases to identify a target of 400 families for genetic analysis. We will establish a cohort of the first and second-degree relatives from these glioma cases to obtain new knowledge about how cancer aggregates in glioma families. We will also acquire biospecimens (blood and tumor tissue), and risk factor data from relevant family members. Aim 2: Identify candidate regions linked to familial brain tumors. To strengthen evidence of linkage to regions found in our preliminary analysis and to identify additional regions linked to brain tumors, we will genotype informative glioma pedigrees identified in aim 1 using Affymetrix 10K GeneChip with markers spaced throughout the genome, and conduct a genome-wide multipoint linkage scan with these markers. Aim 3: Fine map the regions established in Aim 2 by genotyping selected SNPs from genome databases. We will attempt to further refine the regions identified in Aim 2 to less than 1cM by using approximately 1,500 - 2,000 carefully selected SNPs. The prioritization of regions will be based on a combination of the strength of evidence for linkage from families of various ethnic backgrounds and the presence of obvious candidate genes.
Primary Objective: - To assess the efficacy of immediate release methylphenidate, sustained release methylphenidate, and the novel vigilance enhancing drug modafinil for the improvement of cognitive functioning in patients with brain tumors.
The goals of this study are to evaluate each of the following items: 1. Time to recurrence in patients receiving brachytherapy with the GliaSite RTS 2. Overall survival (OS) in patients with malignant brain tumors who are undergoing surgical resection and brachytherapy treatment with the GliaSite® Radiation Therapy System (RTS). 3. Incidence of serious adverse events in patients treated with GliaSite RTS
RATIONALE: Drugs used in chemotherapy, such as temozolomide, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. PURPOSE: This phase II trial is studying how well temozolomide works in treating patients with newly diagnosed anaplastic oligodendroglioma or mixed oligoastrocytoma.

The purpose of this study is to determine if the stereotactic, MR guided, laser interstitial thermal therapy treatment technique can be safety and efficiently used for human brain metastasis and primary brain tumors.
Purpose: The primary objective of this study is to determine if chemotherapy with carboplatin and temozolomide significantly affects the response rates, or size of disease, in patients with brain metastases, originating from cancer in other parts of the body, compared to patients who have already been treated with radiation. Survival, causes of death, recurrence of disease in the central nervous system, toxicity, and quality of life will all be measured as secondary objective in this study.
The purpose of this study is to investigate whether the prophylactic use of itraconazole is a better option than empirical use of itraconazole in the management (prevention and treatment) of fungal infection associated with high-dose chemotherapy and autologous hematopoietic stem cell transplantation in children with high-risk solid tumor.
RATIONALE: Specialized radiation therapy that delivers radiation directly to the tumor may kill more tumor cells and cause less damage to normal tissue. PURPOSE: This phase II trial is studying how well radiation therapy works in treating young patients with gliomas.
Clinical measurement of renal function is generally performed using either laboratory tests or nuclear medicine techniques, however, both of these techniques suffer from some limitations. Notably the lab tests only assess global, rather than individual kidney, function and the nuclear medicine tests are demanding to perform well. Children with brain tumors are often treated with chemotherapeutic in order to try and kill the cancer. Amongst the known side effect of some of the drugs used in the chemotherapy is the fact that they may damage the kidneys. For this reason the function of the kidneys is assessed using a laboratory test at 3 or 6 months intervals during the treatment. In addition, to the problem mentioned above the tests also require a separate visit to the hospital. Children with brain tumors who are undergoing chemotherapy also routinely have contrast-enhanced MRI of the brain performed at intervals of three months in order to evaluate the response of the tumor to the chemotherapy. Recently, MRI techniques have been developed which can evaluate single kidney renal function. The aim of this study is to establish if a single MRI exam can be used to assess both the effect of the chemotherapy on both the tumor and the renal function. The results of the MRI measurement of the single kidney renal function would be combined to provide a measure of global renal function and this would be compared with that obtained from the laboratory test. The MRI exam will require only require an extra 10 minutes of scanning time and will not affect the rest of the MRI exam in any way. This study is being performed to validate a new technique for measuring kidney function. Patients are being asked to volunteer for this study because they require serial contrast enhanced MR scans to monitor their response to chemotherapy. Because some chemo-therapeutic agents can be toxic to the kidney the patient's kidney function will also be evaluated using conventional methods, and the results of these tests can be compared to those obtained using MRI. We plan to study 50 children in this study. The additional procedure for measuring renal function will add 10 minutes to the duration of the MRI exam and will have no effect on the routine brain study. If validated the proposed MRI technique would allow renal function to be evaluated at the time of a routine, contrast enhanced MRI exam and would avoid additional testing using radioactive tracers or urine collection over 24 hours. If successful, MRI could be used to measure single kidney renal function in all any patient undergoing a routine MRI exam by simply extending the scanning time by a maximum of 10 minutes. This would save such patients additional visits to the hospital and would have the advantage of measuring single kidney, rather than global, renal function.
