Filter by: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.
Summary of scientific evidence and rationale of this project: Integrative molecular-genetic approaches have provided important insights in the biology of glioblastoma. It has meanwhile become clear, that glioblastoma is not a single tumor entity but comprises different molecular subtypes, which are associated with a distinct genetic/epigenetic signature and prognosis. Multimodal treatment approaches combining radio- and chemotherapy as well as the recent introduction of novel antiangiogenic agents have resulted in increasing survival times and improved quality-of-life of glioblastoma patients. Yet, despite these intense treatment efforts the therapeutic efficacy in glioblastoma patients is limited, leading in virtually all cases to tumor recurrence and death of the patients. As only a limited fraction of glioblastoma patients undergo second neurosurgery at tumor recurrence (< 10%), post-therapeutic samples are rare and no systematic, large-scale studies exist, which address post-therapeutic morphological and molecular alterations in glioblastoma tumor tissue. Yet, these data would help to improve the understanding of mechanisms involved in therapy-resistance and tumor progression, to develop new therapeutic approaches and could pave the way for personalized treatment strategies.
This research will leverage novel pilot research conducted by the investigators to take important first steps in addressing neurocognitive late effects by intervening early, during treatment, with a promising computerized cognitive remediation program to prevent the downward trajectory of neurocognitive function experienced by pediatric brain tumor survivors. Specifically, we propose to test the feasibility, acceptability, and initial proof of concept of a neuroplasticity-based adaptive cognitive training program (Cogmed) to train working memory (WM) and attention in newly diagnosed youth with a brain tumor. Further, we will test the feasibility of using this intervention in a true prospective design beginning pre-surgery to examine the effects of this intervention in deflecting the downward trajectory of cognitive function in children with brain tumors during treatment. We will also use functional neuroimaging (near infrared spectroscopy - "NIRS") to examine the effects of this program on brain activation in frontal regions that are affected by treatment. Findings from this pilot study will inform the development of a large multi-site randomized efficacy trial to test an individualized cognitive training program. Aim 1. To test the feasibility and acceptability of enrolling youth (7 to 16 years-old) with newly diagnosed brain tumors at time of diagnosis, following patients for 10 weeks, delivering the Cogmed computer-based training program in a randomized trial at 10-weeks post-diagnosis, and following patients to 1 year post-diagnosis. Aim 2. To test the initial acceptability and efficacy of the Cogmed training program on cognitive function in newly diagnosed pediatric brain tumor patients.
Background and purpose: In adult, the half of the CNS neoplasms are metastatic, and high grade astrocytomas and oligodendrogliomas are most frequent malignant tumors among the last half. Recently, integrated MRI-PET (Biograph mMR, Siemens, Germany) was introduced, and can provide simultaneous whole body MRI-PET imaging as well as brain-specific advanced imaging (e.g. DWI, PWI, and DCE). The purpose of the present study is to evaluate whether the simultaneous MRI-PET acquisition can improve the diagnostic yield for the patients initially presented with brain tumors, and predict the prognosis in the patients diagnosed with primary high graded astrocytoma or oligodendroglioma.
The study will compare two different size MRI's of a brain tumor.
The purpose of this study is to test the safety and effects of a special type of a cancer vaccine called a 'dendritic cell vaccine' in patients with either newly diagnosed or recurrent glioblastoma. The goal of this dendritic cell vaccine is to activate a patient's own immune system against their tumor. This study utilizes a patient's own immune-stimulating dendritic cells that are isolated in a procedure called leukapheresis. In a laboratory, these dendritic cells are treated in a way that is designed to promote an immune response against cancer stem cells. Then the dendritic cells are injected under the skin in a series of vaccinations, with the goal of activating an immune response against cancer stem cells in the tumor. To qualify for this study, patients must have very little to no residual tumor visible on a recent MRI. In addition to the vaccines, patients with newly diagnosed glioblastoma will receive standard temozolomide chemotherapy and radiation therapy. Patients with recurrent glioblastoma will not receive any treatment other than the vaccines as long as they are participating in this study, unless they were previously treated with bevacizumab, in which case they will be allowed to continue receiving bevacizumab.
- Metabolic Tumor Volume (MTV), identified by Magnetic Resonance Spectroscopic Imaging (MRSI) is different from the Clinical Target Volume (CTV) used for radiation dose delivery in the treatment of brain tumors. - If MTV > CTV, the investigators hypothesize that the difference in volumes (cc) is related to worse clinical outcome. Furthermore, in case of local recurrence, the lesion is located in the MTV area that is outside of the CTV. - Alternatively, if CTV > MTV, then the difference in volumes is related to higher treatment toxicity.
This is a study for patients with brain tumors called astrocytic tumors. The study will enroll patients who have received standard treatment. The study will test a vaccine called ADU-623. ADU-623 has not been tested in humans before, so the goal of this study is to see if ADU-623 can be given safely to brain cancer patients and what is the better dose to give patients among the three doses that planned to be tested. This study will also evaluate the length of time before patients' cancer worsens and if ADU-623 helps patients to live longer. The study will also measure the body's immune system response to ADU-623.
The objectives of our proposed study are to (a) evaluate the feasibility of conducting a structured exercise program in children treated with cranial radiation for brain tumors, (b) test whether exercise results in improved thinking skills and emotional function, and (c) examine potential mechanisms of improved outcome, particularly recovery of white matter and grey matter.
This protocol is designed to generate and provide preliminary data to determine the safety and activity of combination therapy using tumor treating fields (TTFields; Optune(NovoTTF-100A); Novocure, Haifa, Israel), a novel FDA-approved therapy utilizing alternating electric fields to inhibit tumor cell growth, along with bevacizumab (Avastin; Genentech, San Francisco, CA), a humanized monoclonal antibody that inhibits vascular endothelial growth factor (VEGF), and hypofractionated stereotactic radiotherapy, a highly-focal abbreviated course of brain irradiation, in the treatment of patients with bevacizumab-naive recurrent GBM. Each of these individual therapies, and also several combinations in doublets, has already demonstrated safety and efficacy but prospective clinical data for the concurrent combination of all three therapies are lacking.
