Filter by:The purpose of the research study is to test new methods that could improve diagnosis and assessment of brain tumors. One of these methods is a new MR (magnetic resonance) imaging technique called magnetic resonance fingerprinting (MRF), which allows for rapidly scanning the patient and provides quantitative information on tumor tissue. The investigators will compare the data gathered from MR Fingerprinting with other imaging tests, clinical information, treatment details and biopsy results to evaluate the accuracy of this new technique.
Primary brain cancer kills up to 10,000 Americans a year. These brain tumors are typically treated by surgery, radiation therapy and chemotherapy, either individually or in combination. Present therapies are inadequate, as evidenced by the low 5-year survival rate for brain cancer patients, with median survival at approximately 12 months. Glioma is the most common form of primary brain cancer, afflicting approximately 7,000 patients in the United States each year. These highly malignant cancers remain a significant unmet clinical need in oncology. GBM often has a high expression EFGR (Epidermal Growth Factor Receptor) which is blocked by Cetuximab (CTX). The investigators have recently completed a separate Phase I clinical trial using superselective intra-arterial cerebral infusion (SIACI) of CTX after blood brain barrier disruption (BBBD) for recurrent GBM (Chakraborty et al, in revision, Journal of Neurooncology). The investigators found that intra-arterial infusion of CTX is well tolerated with few adverse effects. The investigators hypothesize that in patients with newly diagnosed GBM, repeated SIACI of this drug after BBBD will be safe and efficacious for our patients when combined with standard chemoradiation (STUPP protocol). This trial will be a non-randomized open label Phase I/II clinical trial. In addition to standard chemotherapy and radiation therapy (STUPP protocol) the patient will be given CTX intra-arterially after BBBD for a total of three doses at approximately post surgery days 30, 120 and 210.

These highly malignant cancers remain a significant unmet clinical need in oncology. GBM often has a high expression of EFGR (Epidermal Growth Factor Receptor), which is associated with poor prognosis. Several methods of inhibiting this receptor have been tested, including monoclonal antibodies, vaccines, and tyrosine kinase inhibitors. The investigators hypothesize that in patients with recurring GBM, intracranial superselective intra-arterial infusion of Cetuximab (CTX), at a dose of 250mg/m2 in conjunction with hypofractionated radiation, will be safe and efficacious and prevent tumor progression in patients with recurrent, residual GBM.
This research study is studying radiation therapy as a possible treatment for meningioma or tumor on the lining of the brain. The study drug or intervention involved in this research study is Intensity Modulated Proton Therapy (IMPT)
Background: Neurobehavioral functions and quality of life (QoL) are the important outcome measurements after radiotherapy in patients with brain tumors and even head/neck cancers. However, few studies have focused on neurobehavioral functions and QoL after anti-cancer treatment particularly brain radiotherapy for pediatric/adolescent patients with brain tumors. This study thus aims to prospectively evaluate those functions in pediatric or adolescent patients with brain or head/neck tumors in order to provide useful information about their clinical outcomes. Methods: A total of 72 pediatric/adolescent patients, who are diagnosed with brain tumors or head/neck cancers, were prospectively recruited. Neurobehavioral functions will be evaluated using a neuropsychological battery, which includes general cognitive functions, intelligence, memory, executive functions, information processing and emotional/behavioral expressions. The QoL will be evaluated by the health-related QoL questionnaire. All participants will be examined at six phases, which include pre-treatment, 1-month post-treatment, 4-month post-treatment, 1-year post-treatment, 2-year post-treatment and 3-year post-treatment. Expected results: Patients'neurobehavioral functions and QoL will show significant improvement after treatment, and the improvement will not be diminished across each post-treatment phase.
During neurosurgical resection of brain tumors within brain areas for motor control, it is important to monitor motor function. For this muscle motor evoked potentials are used. Those are elicited by transcranial and direct cortical stimulation. Motor responses are recorded from muscles. In neurosurgical procedures for spinal cord tumors, the same methods are used, but additionally motor activity is recorded from the spinal cord. This is called spinal motor evoked potentials. It is known that the relation between spinal and muscle motor evoked potentials helps to extent the resection of spinal cord tumors. This study implements the spinal motor evoked potential into brain tumor surgery and analyses the relationship between spinal and muscle motor evoked potentials. With this, detection of injury to the brain area for motor control might be discovered earlier and thus tumor resection can be performed safely.
Background: - More children with cancer are surviving into adulthood. Some side effects from treatment go away quickly. But some problems may not go away or may only show up months or years later. These problems are called late effects. Late effects can cause difficulties in cognitive functions, such as attention and memory. Physical activity has been found to improve the attention and memory skills of children with Attention Deficit Hyperactivity Disorder (ADHD). Researchers want to see if physical activity can help with these cognitive problems in children with brain tumors. Objectives: - To see if physical activity can improve cognitive functions in children who had radiation therapy for a brain tumor. Eligibility: - Children ages 8 17 who had radiation for a brain tumor at least 2 years ago. They must have access to a computer. Design: - Participants will be screened with height, weight, and medical history. They will answer questions about daily physical activities. Their heart will be checked. - Participants will go to the clinic for 2 days. They will have a fitness exam and tests about attention, memory, and concentration. They will have blood taken and answer questions. Parents will also answer questions. - Participants will be put into 2 groups. For the first 12 weeks, the intervention group will follow a physical activity program. The control group will do their usual physical activities. - For the second 12 weeks, the control group will follow the physical activity program. The intervention group will continue the activities on their own. All groups will track their physical activity with an activity monitor and computer. - Participants will have a follow-up visit at the clinic after each session. They will repeat some of the tests listed above. - The study lasts 24 weeks plus the two follow-up visits. Participants can keep their activity monitor.
The outcome of pediatric refractory or relapsed brain tumor is very dismal. Standard chemotherapy showed poor response to these patients. Although tandem high dose chemotherapy with hematopoietic progenitor stem cell rescues has been chosen as a potentially curative therapy for long term survival and better outcome is expected if tumor burden before transplantation reduced by chemotherapy, effective salvage chemotherapy for tumor reduction is not established yet. Irinotecan is a recently developed topoisomerase I inhibitor, and there are preclinical and phase I, II data which proved practical effects in brain tumors. In those studies, irinotecan was administered alone or in combination with one other drug. Vincristine, etoposide, carboplatin, and cyclophosphamide have been used in many protocols for brain tumors but the result was very poor in refractory or relapsed cases. However, irinotecan can be effective with these multiple chemotherapeutic agents. According to the pilot study of irinotecan in combination with vincristine, etoposide, carboplatin and cyclophosphamide in the investigators center, 75% percent of total 12 patients reached more than stable disease, and 2 patients got long term complete remission only with this multi-agent combination chemotherapy. But the combination of irinotecan, vincristine, etoposide, carboplatin, and cyclophosphamide is not clinically studied yet especially for pediatric patients. To improve response rate and progression-free survival, the combination chemotherapy of irinotecan, vincristine, etoposide, carboplatin, and cyclophosphamide is designed for pediatric refractory or relapsed brain tumor.

Two studies (Gerlach et al. 2000; Gerlach et al. 2002) described the impact of factor XIII on the risk of prospective hemorrhage for patients undergoing craniotomy. Since then, factor XIII is measured and substituted in various centers. Few reports support the idea of factor XIII being involved in the formation of deep venous thrombosis and pulmonary embolism. In this prospective observational study, patients undergoing craniotomy for brain tumors or vascular lesions are investigated concerning the incidence of postoperative pulmonary embolism in respect of possible risk factors (factor XIII activity levels, standard coagulation parameters, tumor entity, blood loss).
