Filter by:Background: In vivo experiments have documented the ability of ZD6474 to inhibit tumor growth in various preclinical tumor models. Given the pronounced neovasculature associated with malignant gliomas, and abundant published data demonstrating the dependence of glioma growth on the maintenance and proliferation of this neovasculature, ZD6474 represents a potentially promising new therapeutic approach to these otherwise refractory tumors. Thus, we now propose a phase I trial of ZD6474 in patients with recurrent and progressive low-grade gliomas who are on P450-inducing anti-epileptic drugs and a phase II trial for patients with recurrent gliomas not taking P450-inducing anti-epileptic drugs. Objective: Phase I - To establish the maximally tolerated dose of ZD6474 and to obtain preliminary information regarding the spectrum of toxicities of ZD6474, and to obtain pharmacokinetic data to patients taking EIAED. Phase I - To obtain preliminary information regarding potential anti-tumor activity of ZD6474 in patients taking EIAED. Phase II - To establish data regarding the anti-tumor activity of ZD6474 and to collect information regarding the spectrum of toxicities in patients not taking EIAEDs. Eligibility: Patients with histologically proven malignant primary gliomas will be eligible for this protocol. Additionally, patients with progressive low-grade gliomas and patients with infiltrative brain stem gliomas, diagnosed radiographically rather than by biopsy will also be eligible. Design: Phase I - Group B patients will be accrued to the formal dose-escalation phase I trial. Groups of patients with recurrent high-grade gliomas will be accrued to increasingly higher doses of ZD6474 until the MTD is established. Phase II - Patients will be treated at a dose of 300 mg day, every day, on a 4-week cycle.
Background: Bevacizumab is a genetically engineered antibody that blocks the growth of new blood vessels in tumors. Inhibiting the formation of these blood vessels may slow or stop disease progression by diminishing the supply of life-sustaining nutrients and oxygen the blood delivers to the tumor. Bevacizumab is approved for treating colorectal cancer and has shown activity against brain tumor cells in laboratory and animal tests. Objectives: To examine the safety and side effects of bevacizumab in patients with recurrent brain tumors. To determine the anti-tumor activity of bevacizumab in patients with recurrent brain tumors. Eligibility: Patients 18 years of age and older with a brain tumor that continues to grow after receiving standard treatments. Design: Patients complete the following procedures during the study: - Infusions of bevacizumab through a vein once every 2 weeks in 4-week treatment cycles. - Positron emission tomography (PET) scan before the first dose of bevacizumab, at the end of the first treatment cycle, and as needed after that. - Magnetic resonance imaging (MRI) scan before the first dose of bevacizumab, within 48-96 hours after the first dose of bevacizumab in the first treatment cycle, and then every 4 weeks. One tube of blood for research is collected at the time of each MRI scan to look at specific cells. - Physical and neurological examinations every 2 weeks for the first treatment cycle and then every 4 weeks. - Quality-of-life questionnaires every 4 weeks.
The purpose of this study is to learn whether 3 tesla (3T) MRI functional imaging will map a tumor more accurately allowing a more targeted delivery of radiation. The investigators hope to learn whether tomotherapy will be able to deliver higher radiation doses safely to the tumor while sparing the surrounding normal tissue.
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.
The primary objective is to evaluate and quantify the reproducibility of functional magnetic resonance imaging (fMRI) maps of the eloquent brain areas corresponding to specific neurological functions based on activation maps obtained with different thresholds in patients with benign and biopsy proven low-grade brain neoplasms. Another objective is to access the impairment in neurological function in image guided intracranial radiotherapy using neurocognitive assessment tools and to derive dose response curves relating the impairment in a particular neurological function to the FED received by the area of eloquent brain corresponding to it.
This study is examining whether Vinblastine is an effective drug to shrink low grade glioma brain tumors in children, and what the side effects are.
To explore the relationship between tissue factor levels, tumour progression, activation of blood coagulation and venous thromboembolism with malignant glioma
Patients have a newly diagnosed brain tumor called a malignant glioma and participate in the study to see if it is possible to increase the benefit of temozolomide when given after radiation. A recent study showed that patients with newly diagnosed glioblastoma lived longer when treated with both temozolomide and radiotherapy followed by 6 months of temozolomide than patients treated with radiotherapy alone. Patients will receive standard low dose temozolomide during radiation. After radiation, they will be randomized to receive either more intense temozolomide or continuous low dose temozolomide.
The purpose of this study is to determine whether [18F]FHBG is suitable for use as an imaging probe in cancer or rheumatoid arthritis patients enrolled in cell or gene therapy trials. In this phase 1 study we will assess the safety and biodistribution of [18F]FHBG in patients.
RATIONALE: Radiation therapy uses high-energy x-rays to kill tumor cells. 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. It is not yet known whether radiation therapy is more effective than temozolomide in treating gliomas. PURPOSE: This randomized phase III trial is studying radiation therapy to see how well it works compared to temozolomide in treating patients with gliomas.
