Filter by:This phase II trial studies ferumoxytol in the magnetic resonance imaging of pediatric patients with brain tumors. Magnetic resonance imaging using ferumoxytol may help in viewing a brain tumor and blood vessels in and around the tumor in a different way than the standard gadolinium-based contrast agent. Imaging with this experimental contrast agent may give doctors more information about tumor blood supply and the extent of the tumor itself.
Background: - Glioblastoma (GBM) is the most common malignant brain tumor in adults. Patients with GBM are usually treated with surgery, radiation, and chemotherapy. Despite this treatment, most GBMs start growing again. Bevacizumab, a chemotherapy drug, has shown promise in slowing the growth of GBMs. More research is needed to find out whether having surgery before starting bevacizumab is more effective than bevacizumab alone. Objectives: - To compare surgery plus bevacizumab to bevacizumab alone in adults with glioblastoma. Eligibility: - Individuals at least 18 years old whose glioblastoma has come back after treatment. Design: - All participants will be screened with a physical exam, medical history, blood tests, and imaging studies. - Participants will be divided into two groups. One group will have surgery followed by bevacizumab. The other group will have the drug without surgery. - The first group will have surgery as soon as possible and will begin bevacizumab 4 weeks after surgery. The second group will start the drug as soon as possible. - Both groups will receive the drug as an infusion every 2 weeks. They will be monitored with frequent blood tests and imaging studies. The infusions will continue for as long as the drug is effective at preventing tumor regrowth. - Participants will be contacted every 4 weeks after they stop taking bevacizumab. They will answer followup questions either in person or by telephone.
