Active clinical trials for "Brain Neoplasms"

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.

RATIONALE: Treatment with radiosurgery, temozolomide, and erlotinib may affect brain function (the ability to think, learn, remember, and judge) in patients with non-small cell lung cancer and brain metastases. A study that evaluates brain function may help doctors plan the best treatment. PURPOSE: This phase II trial is studying the effect of radiosurgery, temozolomide, and erlotinib on brain function in patients with non-small cell lung cancer and brain metastases.

The purpose of this study is to assess the relationship between brain malignancy volume as defined by post-contrast T1 weighted and F18 Fluciclovine before and following LITT. We hypothesize that imaging with F18 Fluciclovine will be superior to anatomic MR imaging in lesion volume assessment before treatment and that residual F18 Fluciclovine defined tumor will predict local post-LITT disease recurrence.

This study will develop a whole-of-body markerless tracking method for measuring the motion of the tumour and surrounding organs during radiation therapy to enable real-time image guidance. Routinely acquired patient data will be used to improve the training, testing and accuracy of a whole-of-body markerless tracking method. When the markerless tracking method is sufficiently advanced, according to the PI of each of the data collection sites, the markerless tracking method will be run in parallel to, but not intervening with, patient treatments during data acquisition.

The goal of this clinical research study is to learn about using Navigated Transcranial Magnetic Stimulation (nTMS) in patients having surgery to remove a brain tumor in areas of the brain that control movement (motor function) and/or speech. nTMS is a system designed to map the brain's function relating to movement and speech.

This is a pilot study to assess the changes in white matter, in the brain, in response to radiation therapy and correlate these changes with later declines in cognitive function.

The study investigates valproic acid added to radiation and temozolomide therapy (standard of care) for progressive or recurrent pediatric brain tumors.

Patients in good general condition with resectable brain metastases, looks better with more intense treatment of metastases. This local treatment has been accomplished with surgery or radiosurgery. However, there are no randomized studies comparing these two types of treatment. The purpose of this study is to make this.

Patients with confirmed advanced NSCLC and any response to 3-6 cycles of chemotherapy, were randomized to receive PCI (30 Gy/10fr) or no PCI. The primary endpoint was the cumulative incidence of symptomatic brain metastases (BM) . The study was sized to detect a hazard ratio of 0.37 with 80% power and 2-sided 5% significance (60 events, 206 patients).

This phase II trial studies how well magnetic resonance imaging (MRI) using contrast imaging agent ferumoxytol works in comparison to standard imaging agent gadolinium in measuring tumors in patients undergoing treatment for brain tumors or other tumors that have spread to the brain. Diagnostic procedures, such as MRI, may help find and diagnose disease and find out how far the disease has spread. MRI scans use radio waves and a powerful magnet linked to a computer to create detailed pictures of areas inside the body. The contrast imaging agent ferumoxytol consists of small iron particles taken by the blood stream to the brain and to the area of the tumor. It is highly visible on the MRI, and may help visualize the blood flow going through the tumor better than gadolinium can. Using a more sensitive and faster 7 Tesla (7T) magnet MRI in conjunction with a contrast imaging agent may provide a better way to measure tumors than the 3 Tesla (3T) magnet MRI in patients with brain tumors.
