Active clinical trials for "Glioma"

This is a pilot study. The purpose of this study is to test if an imaging tracer, not approved by the FDA, called 11C-Choline (11C-CH) is useful for evaluating your type of cancer. This tracer is used to perform PET scans. The researchers want to see if the 11C-CH PET scan, using the study tracer 11C-CH, can improve upon the usual scans at diagnosing or monitoring your type of cancer. In patients with high-grade gliomas, changes on standard MRI of the brain may reflect true tumor growth or inflammatory changes in response to treatment, called pseudo-progression. It is important to distinguish true tumor growth from inflammation since inflammation indicates the tumor is responding to treatment. With standard MRI, it is difficult to determine if changes following treatment are due to tumor growth or inflammation early on. Researchers hope to learn if the investigational tracer, 11C-CH, will be able to distinguish true tumor growth from inflammation more accurately than standard MRI or 18F-FDG PET scans.

MET PET and MRS are often performed as imaging tool for the differential diagnosis of gliomas. But both techniques have limitations causing misdiagnosis; thus, the investigators tried to combine these two imaging tools to study whether the combination of MET PET and MRS could raise the diagnosis ability of the radiological diagnosis of gliomas.

This study is being conducted to help determine whether β-elemene as maintain treatment for complete remission patients of newly diagnosed malignant gliomas following standard treatment, is able to delay tumor growth, or impact how long people with newly diagnosed high-grade glioma.

The purpose of this study is to evaluate high and low areas of growth, or proliferation, within the tumor. An imaging technique using a very small amount of a radioactive tracer called 18Ffluoro-deoxy-L-thymidine (18F-FLT) can detect areas of rapid growth within the tumor. This imaging technique is called a FLT PET imaging. This present study involves obtaining one scan using FLT PET imaging. The goal of this study is to investigate associations between the imaging findings showing differences in growth rate within the tumor and the biology of the tumor that is measured in the sampled tumor tissue. This information may be used in future brain tumor patients to determine the best combination of treatment for individual patients. These studies may also improve our understanding of the types of changes taking place in brain tumor tissue that could improve individual patient outcome. FLT is produced for human use by the MSKCC cyclotron facility under an investigational new drug (IND) approval issued by the US Food and Drug Administration (FDA). This means that FLT is produced under strict rules and regulations, is considered safe, and has been approved for use in humans for certain disease conditions. 18F-FLT has been used in several research studies to date at this institution.

The purpose of this study is to assess patient satisfaction, the efficacy and compliance of granisetron patch versus ondansetron pills for radiation induced nausea and vomiting in malignant glioma patients receiving six weeks of radiation therapy (RT) and concomitant temozolomide (TMZ). Use of the patch may benefit brain tumor patients by increasing compliance. All eligible adult malignant glioma subjects should receive a planned total dose of 54-60 GY of radiation and 75 mg/m2 of daily TMZ for a total of six weeks. Subjects will be randomized to receive either granisetron patch or ondansetron for three weeks. Weeks 3-6, they will received the other medication. The granisetron transdermal delivery system (supplied as a 52 cm^2 patch containing 34.3 mg of granisetron - 3.1 mg/day) is applied once per week 24 hours before the weekly radiation and chemotherapy, while the ondansetron 8 mg oral tablet is taken once a day 30-60 minutes prior to each dose of chemotherapy. Subjects will fill out questionnaires regarding the effectiveness of the medication and their satisfaction, and which anti-emetic they prefer. Safety will be assessed throughout the six weeks of radiation by the clinical research nurse using the Common Toxicity Criteria for Adverse Events (CTCAE), version 4.0. All subjects who receive both ondansetron and Granisetron Transdermal Delivery System (GTDS) treatment will be included in analyses of treatment preference. However, all other efficacy and safety analyses will include all subjects who received ondansetron or GTDS.

To investigate a computer-based Cognitive Remediation Therapy (CRT) for brain tumor patients at the Massey Cancer Center on measures of cognitive functioning (e.g., working memory, attention, processing speed, language, visuospatial functioning, immediate and delayed memory, or executive functioning) over time.

Post-marketing surveillance to investigate the clinical safety and effectiveness in patients of all implantation of Gliadel with malignant glioma in the actual medical setting.

5-ALA and the Orbeye surgical microscope are U.S. Food and Drug Administration (FDA) approved products. For this study, the Orbeye microscope imaging system is being used with special filters to visualize 5-ALA fluorescence. The FDA currently permits the use of these filters. The purpose of this study is to collect medical information before, during, and after standard treatment in order to better understand how to make this type of procedure accessible to patients. This study is also being conducted to determine if use of the Orbeye equipped with these special filters improves the ability of the surgeon to remove brain tumors.

This pilot study will assess feasibility and to obtain initial estimates of efficacy of Sleep Activity and Task Effectiveness (SAFTE) model, which can accurately estimate the impact of scheduling factors and sleep history on both safety and productivity. The SAFTE model will be used to asses cancer-related fatigue and study potential associations of change in sleep patterns to tumor recurrence in patients with high grade glioma. Data will be collected using the Readiband™ Sleep Tracker (https://www.fatiguescience.com/sleep-science-technology/). The Readiband device captures high-resolution sleep data, validated against the clinical gold standard of polysomnography with 92% accuracy. Sleep data is transmitted to the cloud automatically for SAFTE Fatigue Model analysis. We will correlate clinical progression data obtained from the patient's electronic medical record with SAFTE data.

Background: Diffuse low-grade gliomas (DLGG) are slow-growing primary-cancer of the brain and spinal cord. They represent up to 15% of the developing tumors in those organs with fatal outcome for the patients because of their evolution. The reasons for this transformation towards more malignant tumors still remain ill defined. Previously, the research team in neuro oncology at Montpellier University Hospital found foci of tumor heterogeneity within 20 to 30 % of the patients developing a DLGG and published their results. The investigators assumed that those foci represent the early beginning of the transformation from a diffuse low-grade glioma to a glioblastoma, tumor with highly malignant cells and a life expectancy of two years in average for the patient. Methods: The investigators selected adult patients with no prior surgery nor neuro oncology treatment when enrolled. They presented a specific mutation for an enzyme of the metabolism named IDH1, standing for Isocitrate Dehydrogenase 1, found in 70% of DLGG. Patients were also selected because they presented foci of tumor heterogeneity. After obtaining their consent, the investigators studied by immunohistochemistry the pathways deregulated between the DLGG and the foci. The investigators also extracted RNAs, molecules expressing the life and metabolism of tumor cells, and compared them to know what genes were differentially expressed between the DLGG and the foci. All RNAs were tested for quality control prior to be processed further. The investigators then studied 8 patients with compliance with ethics, authorizations and institutional guidelines. Genes of interest were studied in vitro to assess their functions. The investigators found a barely described enzyme of the catabolism of the phosphoethanolamines and discovered a new anti-proliferative tumor-role for it. •Discussion: The investigators first showed that foci have a higher percentage of p-STAT3+ cells which indicates STAT3 pathway activation in these cells. Phosphorylated STAT3 translocates to the cell nucleus to regulate many genes involved in proliferation, apoptosis and angiogenesis. As such, phosphorylation of STAT proteins, notably STAT3, is involved in the pathogenesis of many cancers, including GBM, by promoting cell cycle progression, stimulating angiogenesis, and impairing tumor immune surveillance. The investigators found that ETNPPL RNA and protein are reduced in foci cells and absent in glioblastomas. This is consistent with glioma database analyses showing that ETNPLL expression is inversely correlated to STAT3 and MKI67 whose expression are higher in foci and glioblastomas. In addition, Kaplan-Meier analysis shows that patients with low expression of ETNPPL have lower overall survival These observations suggested that this enzyme may oppose glioma cells proliferation. The investigators demonstrated this hypothesis by overexpressing ETNPPL in 3 glioblastoma cell cultures. Two were sensitive to ETNPPL overexpression which reduced their growth while no effect was detected in Gli4 cells. These glioblastoma-derived cultures have different types of mutations.
