Filter by:The purpose of this study is to demonstrate non-inferiority of Dotarem®-enhanced MRI as compared to Gadovist®/ Gadavist®-enhanced MRI in the diagnosis of brain tumors in terms of overall lesion visualization and characterization (off-site assessment). 270 patients will be randomized between 2 arms defining the sequence of administration of the contrast agents at the dose of 0.1mmol/kg, with a minimum of 48 hours and a maximum of 14 days in between. Each patient will, therefore, receive two MRI during his/her participation in the study. The two arms consist in : - Dotarem® in the first MRI, then Gadovist®/Gadavist® in the second MRI. - Gadovist®/Gadavist® in the first MRI, then Dotarem® in the second MRI. Contrast-enhanced MRIs will be performed on 1.5 or 3 Tesla systems. MRI examinations will be evaluated centrally by blinded independent readers for the main evaluation criterion.
Purpose of the study: AIM 1 Prospectively collect pre-operative (fMRI, DTI, MEG) and intra-operative mapping data in patients with intra-axial brain tumors to assess how well each modality predicts the location of eloquent brain function. In addition, each modality will be compared with the other. AIM 2 Assess reorganization of eloquent brain function and plasticity in patients with intra-axial brain tumors. This will be accomplished by prospectively collecting post-operative mapping studies and neuropsychological tests to compare them to prior mapping studies as stated above.
The management of glioblastoma in elderly patients with poor performance status (KPS<70) is unsettled. This single arm phase 2 trial trial was designed to evaluate the efficacy and safety of temozolomide alone in this population
To determine the safety of prophylaxis with Tinzaparin low molecular weight heparin in primary brain tumor patients. 2. To determine the incidence of deep venous thrombosis or pulmonary embolism in brain tumor patients who will be receiving Tinzaparin as primary prophylaxis. 3. To determine the overall survival of patients with malignant glioma who receive Tinzaparin. 4. To determine the bone density before and after prophylactic Tinzaparin.
Specific Aim 1: To assess the feasibility and acceptability of a home-based, computerized attention training program with survivors of central nervous system (CNS) impacting pediatric cancer (e.g. acute lymphocyte leukemia [ALL], brain tumors). Specific Aim 2: To estimate the effect size of this attention training program with survivors of childhood cancer to determine whether a larger-scale clinical trial is warranted.
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
The purpose of this study is to determine the feasibility, efficacy and safety of intravenous and oral antiepileptic treatment with levetiracetam in patients with primary brain tumors and symptomatic epilepsy in the period of neurosurgical intervention.
A randomized trial comparing radiotherapy with supportive care in patients aged 70 years or older with newly diagnosed, histologically confirmed anaplastic astrocytoma or glioblastoma, and a Karnofsky performance status > 70.
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 critical importance. Currently, surgical biopsy is required to make this differentiation. Healthy volunteers and patients who have received radiation therapy as part of their treatment for a brain tumor may be eligible for this study. All candidates must be at least 21 years old. Patients must have a new area of abnormality that requires a biopsy to determine whether it is a tumor recurrence or radiation necrosis. Candidates are screened with a medical history and physical examination. In addition, patients have blood and urine tests. All participants undergo MRI and DT-MRI. MRI uses a strong magnetic field and radio waves instead of X-rays to obtain images of body organs and tissues. The MRI scanner is a metal cylinder surrounded by a strong magnetic field. During the MRI, the subject lies on a table that can slide in and out of the cylinder and wears earplugs to muffle loud knocking noises that occur during the scanning. Scanning time varies from 20 minutes to 3 hours, with most scans lasting 40-60 minutes. Subjects may be asked to lie still for up to 20 minutes at a time. DT-MRI is a type of MRI that measures how water moves in the brain tissue. This technique uses the same MRI machine as conventional MRI, but the diffusion images are obtained after the normal MRI scan, and by a computer program that is installed into the machine. This completes the participation of healthy subjects. In addition to the scans, patients undergo brain biopsy of the abnormal areas identified by MRI. Patients' commitment to the study protocol is fulfilled when the surgery is complete; they may, however, continue to receive follow-up care at the NIH Clinical Center after they complete the study. They are given the results of the biopsy so that further treatment, if necessary, can be arranged.
Numerous studies document the ability of tumors to shed DNA into the blood stream. Circulating DNA can thus be recovered for analyses, representing a surrogate tumor material to test for potential applications in disease diagnosis and prognosis. Detection of genetic alternation is one of the most important tests for cancer patient since they offen correlated with the clinical course, prognosis and chemosensitivity of primary brain tumors. Currently in brain tumor patients these molecular aberrations can be analyzed only on tumor tissue that was obtained at surgery or biopsy. Paucity of pathologic samples or poor fixation technique often make the tissue samples unassessable for molecular aberrations. Therefore, the ability to extract tumor DNA from peripheral blood holds a great clinical significance. Still, the molecular aberration evaluated on serum DNA should be correlated and verified by comparison to standard evaluations performed on tumor samples. Our study aim is to evaluate the feasibility of using serum DNA for routine diagnosis of tumor molecular aberrations.
