NCT01535430
Purpose of the study: AIM 1: Prospectively collect pre-operative \[functional magnetic resonance imaging (fMRI), diffusion tensor imaging (DTI), magnetoencephalography (MEG)\] and intra-operative mapping data in patients with intra-axial brain tumors to assess how well each modality predicts the location of eloquent brain function. In addition, each modality will be compared with the other. AIM 2: Assess reorganization of eloquent brain function and plasticity in patients with intra-axial brain tumors. This will be accomplished by prospectively collecting post-operative mapping studies and neuropsychological tests to compare them to prior mapping studies as stated above.
NCT06804655
Advanced technology of ex vivo drug profiling referred to as pharmacoscopy may allow to identify novel drugs for the treatment of glioblastoma and other refractory brain tumors at an individual patient level. This personalized therapeutic approach was developed and validated in pre-clinical glioma models. With the current research proposal, we seek to establish feasibility for a clinical interventional trial for patients with refractory primary brain tumors that is based on pharmacoscopy-guided selection of treatment. The study is supported by an unrestricted grant from Anti Cancer Fund.
NCT05634707
The purpose of this research study is to determine if fluoxetine increases lysosomal stress in patients with recurrent IDHwt glioma by evaluating LAMP1 expression in tumor samples obtained pre-resection via biopsy and during surgery. Lysosomes are organelles (structures in cells) that contain digestive enzymes (substances that break down chemicals) that help keep the cells free of extra or worn out cell parts. Fluoxetine, a drug approved by the FDA to treat problems like depression and anxiety, can cause changes to structures in cells called lysosomes that then improve how well the chemotherapy drug temozolomide (TMZ) kills cancer cells in the brain.
NCT01472731
Brain tumors account for only 2% of all cancers but result in a disproportionate share of cancer morbidity and mortality. The five-year survival rates for the most common histologic subtypes, anaplastic astrocytoma and glioblastoma (glioblastoma multiforme, GBM), are 30% and 10%, respectively. Drugs affecting transforming growth factor-β (TGF-β) might be of great interest for malignant glioma treatment. TGF-β is an oncogenic factor in advanced tumors where it induces proliferation, angiogenesis, invasion, and metastasis as well as suppresses the antitumoral immune response. In addition TGF-β and its TGF-β receptors, TβRI and TβRII, are overexpressed in GBMs. TGF-β signaling is involved in multiple steps of GBM development. GC1008 is an antibody that is capable of neutralizing TGF-β and may therefore offer a new treatment option for patients with malignant glioma. For therapeutic success, it may be essential for GC1008 to reach the target site, in this case located in the brain. We will be able to prove this with 89Zr-GC1008 PET imaging. This imaging method also allows quantification of the amount of GC1008 reaching the tumor. This study consists of 2 parts. In part 1, patients with a suspicion of a malignant glioma undergo an 89Zr-GC1008 PET scan before standard (surgical)treatment. In part 2, patients with relapsed malignant glioma will undergo an 89Zr-GC1008 PET scan and will be treated with GC1008 in a phase II study as there is no standard treatment for these patients. We hypothesize that GC1008 uptake in brain tumors can be visualized and quantified using the 89Zr-GC1008 PET scan and GC1008 might offer a new treatment option for patients with relapsed malignant gliomas.
NCT02389855
The NeuroBlate® System (NBS), is a minimally invasive robotic laser thermotherapy tool. It employs a pulsed surgical laser to deliver targeted energy to abnormal brain tissue caused by tumors and lesions. Since receiving FDA clearance in April 2013, the NBS has been used in nearly 300 procedures conducted at approximately 20 leading institutions across the United States. This post-market, multi-center retrospective study is designed to collect long-term follow-up data on patients who were treated previously with NBS.
NCT05660499
Despite medical advances, cancer remains the leading cause of death by disease in children. Brain tumors are the second most common cause of cancer in children after leukemia, representing 25% of pediatric cancers. The overall survival rate is about 50% with extremes ranging from less than 5% to more than 90% depending on the histological type of brain tumor. The end of life of children with a brain tumor is marked by the possibility of discomfort symptoms, painful or not, and by a progressive neurological deterioration, which makes the management of these children complex for both families and health professionals. Over the last decade, the concept of palliative care has been increasingly integrated into pediatric onco-hematology services with the primary objective of better symptom control in a global approach to the child and his or her family in order to aim at a better quality of life.
NCT04919993
The purpose of this study is to pilot test an empirically supported psychotherapeutic intervention, Cognitive Behavior Therapy for Insomnia (CBT-I) in primary brain tumor patients. Researchers hope to better understand the feasibility and acceptability of this intervention in neuro-oncology, as well as the preliminary potential benefits of this intervention on brain tumor patients' sleep, fatigue, mood, quality of life, and chronic inflammation. This may lead to improvements in treating insomnia in primary brain tumor patients.
NCT00241670
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.
NCT00265174
Numerous studies document the ability of tumors to shed DNA into the blood stream. Circulating DNA can thus be recovered for analyses, representing a surrogate tumor material to test for potential applications in disease diagnosis and prognosis. Detection of genetic alternation is one of the most important tests for cancer patient since they offen correlated with the clinical course, prognosis and chemosensitivity of primary brain tumors. Currently in brain tumor patients these molecular aberrations can be analyzed only on tumor tissue that was obtained at surgery or biopsy. Paucity of pathologic samples or poor fixation technique often make the tissue samples unassessable for molecular aberrations. Therefore, the ability to extract tumor DNA from peripheral blood holds a great clinical significance. Still, the molecular aberration evaluated on serum DNA should be correlated and verified by comparison to standard evaluations performed on tumor samples. Our study aim is to evaluate the feasibility of using serum DNA for routine diagnosis of tumor molecular aberrations.
