Filter by:RATIONALE: Talabostat may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as temozolomide and carboplatin, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving talabostat together with temozolomide or carboplatin may kill more tumor cells. PURPOSE: This phase I trial is studying the side effects and best dose of talabostat when given together with temozolomide or carboplatin in treating young patients with relapsed or refractory brain tumors or other solid tumors.
RATIONALE: Zoledronate may prevent bone loss in patients with primary malignant glioma. PURPOSE: This phase II trial is studying how well zoledronate works in preventing osteoporosis in patients with primary malignant glioma.
Brain tumours often have low oxygen levels, and that makes them more resistant to radiation therapy. If patients breathe the right mixture of oxygen during treatment, radiation may work better. In this study, patients with brain tumour will undergo a special MRI test while they breathe different mixtures of oxygen and carbon dioxide to find out whether oxygen levels improve in the tumor. Patients will also be asked to repeat this MRI test during the second week of radiation therapy, as well as 3 months, 6 months and 1 year after RT. The MRI test after RT will help us understand how the blood vessels in the normal brain are affected by radiation.
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.
The aim of this study is to evaluate non-inferiority of salvage stereotactic radiosurgery (SRS) in the patients who received surgical resection for brain metastases in comparison with postoperative whole brain radiation therapy (WBRT).
The aim of the study "Fluorescence-guided resection of malignant gliomas with 5-Aminolevulinic acid (5-ALA) vs. conventional resection" is to determine how accurately contrast agent-accumulating tumour can be removed by primary surgery and to assess the clinical usefulness of this method.
3D ultrasound is a new modality used in image guided neurosurgery. a multicentre study is started for the evaluation of this tool as a means for achieving total resection of brain tumors at greater safety.
The purpose of this study is to examine the long-term safety and tolerability of human corticotropin-releasing factor (hCRF), XERECEPT®, in patients requiring dexamethasone (Decadron) to treat peritumoral brain edema. This open-label, extended-use study is open to all patients who participate in either of the blinded studies, NTI 0302, NTI 0303, or other designated studies, including patients who may have discontinued blinded study medication early but completed the protocol-stipulated follow-up periods.
The study objective is to evaluate the safety and efficacy of patupilone with respect to early progression and response of patients with non-small cell lung cancer (NSCLC) metastatic to the brain, who have progressed after chemotherapy, surgery and/or radiation.
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.
