Active clinical trials for "Brain Neoplasms"

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.

This is a single site, investigator initiated study that aims to explore the feasibility of using a personalized 3D printed immobilization mask for CNS patients undergoing radiation therapy. For the purpose of this study, patients will undergo the standard CT SIM, and MR SIM necessary for radiation therapy, creating the masks from the MRIs. Prior to the start of their treatment, patients will have an additional CT scan with the 3D printed mask to confirm safety and treatment accuracy. Patients will then proceed with their standard radiation therapy, immobilized with the mask. There will be a control group that will be treated with the standard thermoplastic mask, as a comparison measure. Both groups will complete a mask tolerability questionnaire throughout the course of their treatment to capture the level of discomfort patients may feel with either masks.

This trial studies how well stereotactic radiation therapy before surgery works in treating patients with cancer that has spread to the brain (brain metastases) and can be removed by surgery (resectable). Stereotactic radiation therapy is a specialized radiation therapy that delivers a single, high dose of radiation directly to the tumor, and may cause less damage to normal tissue. Giving stereotactic radiation therapy before surgery may make the return of brain metastases less likely and help patients live longer compared to surgery followed by radiation therapy.

To evaluate the efficacy of eribulin for treatment of HER2-negative breast cancer brain metastases (BCBM)

The hypothesis of this study is that the addition of NovoTTF-100A System treatment to salvage chemotherapy will significantly increase time to treatment failure in the brain of small cell lung cancer patients.

A phase II trial evaluating Cabazitaxel in patients with brain metastasis secondary to breast and non-small-cell lung cancer (NSCLC). OBJECTIVES: Primary: The purpose of this study is to determine if cabazitaxel can induce a reduction in the size brain metastasis in metastatic HER2-negative breast cancer and NSCLC with brain metastasis who were not previously treated with whole brain irradiation or require immediate brain irradiation. Secondary: To determine the effect of cabazitaxel on the time to initiating whole brain irradiation or radiosurgery To determine the effect of cabazitaxel on the time to developing neurological symptoms To determine the effect of cabazitaxel on the time to disease progression in the brain To determine the effect of cabazitaxel on the time to disease progression outside the brain. This will be evaluated separately for the breast and NSCLC cohorts To determine the objective extra-cranial response (if applicable). This will be evaluated separately in the breast and NSCLC cohorts To determine the safety of cabazitaxel

This pilot clinical trial study will assess the inflammatory response of brain tumors or other central nervous system conditions in pediatric and adult patients using ferumoxytol-enhanced MRI. Imaging features will be correlated with the number of inflammatory cells (macrophages) at histopathology. Determining the extent of inflammation associated with pathologies in the central nervous system may be helpful for diagnostic and prognostic purposes as well as monitoring treatment response of current and future immunotherapies.

Background: - The anti-cancer drug RO4929097 is being tested for its ability to block blood vessel growth to tumors and slow or stop the growth of cancer cells. However, it has been used in only a small number of adults and has not yet been tested in children. Researchers are interested in determining whether RO4929097 is a safe and effective treatment for tumors or leukemia that has not responded to standard treatment. Objectives: - To determine the safety and effectiveness of RO4929097 as a treatment for children and adolescents who have been diagnosed with certain kinds of cancer that have not responded to standard treatment. Eligibility: - Children, adolescents, and young adults between 1 and 21 years of age who have been diagnosed with solid, nervous system, or blood-based cancers that have not responded to standard treatment. Design: Participants will be screened with a medical history, physical examination, blood and urine tests, and imaging studies. Some participants may also have a bone marrow biopsy to evaluate the state of their disease. Participants will be separated into three groups: One group will receive RO4929097 alone, and the other two will receive RO4929097 in combination with the immune-suppressing drug dexamethasone. RO4929097 will be given as tablets on one of two schedules: days 1 to 3 of every week (Schedule A) or days 1 to 5 of every week (Schedule B). The dosing schedule will be determined randomly. Every 4-week treatment period is one cycle, and participants may receive RO4929097 for up to 24 cycles. Participants will have frequent blood and urine tests and imaging studies to evaluate the progress of treatment, and will be asked to keep a diary to monitor any side effects.

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.

To verify the number of metastatic brain tumors detected in contrast-enhanced MRI, which is the primary variable, increases after an additional dose of Magnevist (SH L 451A) comparing images after an initial dose (0.1 mmol/kg) with those after an additional dose (0.1 mmol/kg, a total dose of 0.2 mmol/kg) intra-individually in patients with metastatic brain tumors. Safety was also to be assessed.
