Filter by:The purpose of this study is to test the safety of a new plan for treating glioblastoma. The usual first treatment for glioblastoma is to give focused radiation over 6 weeks in combination with a chemotherapy called temozolomide. In this study the radiation will be given over 2 weeks in combination with temozolomide and another drug, bevacizumab, will also be given. Our idea is that this treatment plan may attack both the tumor and the blood vessels feeding the tumor more effectively. This study will look at what effects, good or bad, this approach has on the patient and the tumor.
The main purpose of this study is to evaluate the safety and performance of the AutoLITT system for the treatment of recurrent/progressive glioblastoma multiforme tumors (GBM).
The purpose of this study is to determine normal measurements (ADC values) from the head and neck of healthy volunteers using 3T MRI.
Meningiomas account for 20% of primary adult brain tumors, occurring at an annual incidence of 6 per 100,000 (Louis, Scheithauer et al. 2000). Complete surgical resection is the treatment of choice but may not possible when the tumor invades critical structures (e.g., skull base, sagittal sinus) (Mirimanoff, Dosoretz et al. 1985; al-Rodhan and Laws 1990; Al-Rodhan and Laws 1991; Newman 1994; De Monte 1995; Levine, Buchanan et al. 1999; Barnett, Suh et al. 2000; Ragel and Jensen 2003). Up to 20% of meningiomas exhibit a more aggressive phenotype that does not respond to standard therapies (Kyritsis 1996). Adjuvant therapies are critical for patients with this subset of meningiomas. Radiation therapy and stereotactic radiosurgery are good adjuvant therapies but are limited by radiation neurotoxicity, tumor size constraints, and injury to adjacent vascular structures or cranial nerves (Goldsmith, Wara et al. 1994; Barnett, Suh et al. 2000; Goldsmith and Larson 2000). Standard chemotherapeutic treatments have been disappointing (Kyritsis 1996). Even drugs like temozolomide that have shown efficacy against malignant brain tumors have failed to inhibit the growth of refractory meningiomas in a phase II study (Chamberlain, Tsao-Wei et al. 2004).
The purpose of this study is to use an imaging method called functional magnetic resonance imaging (fMRI) in patients who have a tumor near an area of the brain that is believed to control language. The fMRI is a new kind of imaging that uses a strong magnetic field to look at functioning brain tissue. This kind of imaging will be used to study the effect of the brain tumor on your speech.
This research protocol makes pictures of brain tumors. The pictures are made with a positron emission tomography (PET) scanner. PET scans use radioactivity to "see" cancer cells. We are using a new kind of PET scan. The new PET scan is called [18F]-FACBC PET. We will compare this to the standard PET scan. The standard PET scan is called [11C]-methionine PET. We expect these pictures will give us information about your tumor. We also hope to collect information about the amount of radioactivity exposure. We will measure radioactivity exposure to your tumor, brain and other organs. The research study results will be used to support the submission of an investigational new drug (IND) application to the Food and Drug Administration (FDA).
This is a pilot study. The goal of this study is to test whether Bevacizumab is safe enough in patients with brain tumors so that a larger study can be conducted. This study will also give us some information about whether the combination of Bevacizumab and radiation has potential to become an effective treatment for regrowing brain tumors. Bevacizumab is an experimental drug that blocks a molecule called VEGF that is found in high amounts in malignant gliomas. VEGF promotes the growth of blood vessels that bring nutrients to tumor cells. In studies with laboratory animals, Bevacizumab slowed the growth of several different types of human cancer cells by blocking the effects of VEGF. There is also evidence that Bevacizumab enhances the effects of radiation on tumor cell
A significant number of brain tumor patients who received radiation or chemotherapy have thinking problems as a result of their treatment. The purpose of this study is to find out if treatment with Aricept (donepezil) may improve some aspects of thinking abilities in patients with brain tumors who received radiation or chemotherapy. This research will also study whether persons having particular genes for a blood-borne substance called apolipoprotein E (APOE) are more likely to have thinking problems after radiation or chemotherapy treatment for their brain tumors. The findings of this study will help us find out whether Aricept can improve thinking abilities after cancer treatment, and whether some of the thinking difficulties may be in part related to having certain genes.
The purpose of this study is to test the effectiveness of perifosine in preventing further tumor growth using the established optimal dose of the drug. A second goal is to determine if perifosine can block the molecules in the tumor that drive it to divide and grow.
The purpose of this study is to obtain chemical information from part of your body without a biopsy. This is done using a technique called magnetic resonance spectroscopy (MRS) which is similar to magnetic resonance imaging (MRI) except that signals are detected from the chemicals (spectroscopy) naturally present in your body using radio waves. To receive this information from your body, small loops of wire (surface coils), placed near the tissue of interest, may be used to more effectively detect signals that come from the chemicals in your body. The investigators may use a second radio channel simultaneously, which will allow us to obtain greater chemical information (decoupling). The results may also help us to understand how this study can be used to help other patients with your condition.
