Cognitive Changes of IDH-mutant and IDH-wildtype Glioma Patients After Chemoradiotherapy With Radiation Dose to the Resting State Networks
Neurocognitive decline after radiation therapy is one of the most concerning complication for brain tumor patients and neuro-oncologists. There are increasing technological advances in evaluating the brain's neural connections responsible for the neurocognitive processes. For example, resting-state functional MRI (RS-fMRI) is an advanced imaging method that can identify the spatiotemporal distribution of the intrinsic functional networks within the brain (also referred to as resting state networks (RSNs) without requiring specific tasks by the imaged participants. Although there is evidence that shows that avoidance of specific neural networks during radiation therapy planning...

Cognitive Function After Radiation Therapy for Primary Brain Tumours
This study will assess cognitive function in patients with a primary brain tumour treated with radiation therapy (RT) to generate radio-sensitivity and volume effect parameters for the development of cognitive dysfunction. All types of brain tumours apart from glioblastoma will be included.

Cognitive Outcomes After Brain Substructure-informed Radiation Planning in Pediatric Patients
The goal of this trial is to determine whether it is possible to minimize radiation dose to parts of the brain that are important for thinking and learning in children who require radiation to treat their tumor, and if this will help reduce neurocognitive (thinking and learning) impairments in these patients. Patients with newly diagnosed brain or head and neck tumors who are having radiation therapy will have neurocognitive testing and MRI imaging (both research and for regular care) done as part of their participation in the study. Survivors of childhood brain tumors who completed radiation therapy at least two years before joining the study, and have not had a recurrence,...

Cognitive Status After Removal of Skull Base Meningioma
The purpose of this prospectively enrolling trial is to assess long-term cognitive outcomes of patients undergoing surgery for resection of a meningioma associated with the frontal and temporal lobes.

Cognitive Training in the Virtual Reality Setting With Children Undergoing Radiotherapy for Brain Tumors
The objective of this study is to estimate the feasibility and acceptability of cognitive training in the virtual reality setting with children undergoing radiotherapy for brain tumors. To achieve this goal, the investigators plan to study children undergoing radiotherapy for brain tumors randomly assigned to cognitive training administered via an iPad or virtual reality. Both groups will also participate in cognitive testing and exams using functional near infrared spectroscopy (fNIRS) pre- and post-intervention. The questions to be investigated are: 1. Will cognitive training via virtual reality be feasible and acceptable for children undergoing radiotherapy for brain...

Collecting Blood Samples From Patients With and Without Cancer to Evaluate Tests for Early Cancer Detection
This study collects blood and tissue samples from patients with cancer and without cancer to evaluate tests for early cancer detection. Collecting and storing samples of blood and tissue from patients with and without cancer to study in the laboratory may help researchers develop tests for the early detection of cancers.

Collection of Blood and Urine Samples in Patients Receiving Radiation Therapy for Glioblastoma Multiforme
This study will collect blood and urine samples from patients undergoing radiation therapy for glioblastoma multiforme (a type of brain tumor) to investigate the effects of this treatment on blood cells and certain proteins. The information from this study may help scientists develop new tests to measure radiation exposure and find new ways to treat cancer with radiation, and help determine which kinds of patients or tumors respond better to radiation therapy. Two proteins of particular interest in this study and which may be involved in the recurrence of cancer are VEGF (vascular endothelial growth factor) and MMPs (matrix metalloproteinases). Patients 18 years of age and older...

Combination Immunotherapy Targeting Melanoma
The purpose of this study is to assess the feasibility, safety and efficacy of combination immunotherapy based on CAR T cells, cytotoxic T lymphocytes (CTLs), and dendritic cell (DC) vaccines modified with GM-CSF and B7-2 (CD86) against melanoma, which targets CAR T specific surface antigens such as GD2, CTL specific antigens such as MAGE-A4, gp100 and a pool of melanoma specific antigens presented by the DCs. Another goal of the study is to learn more about the function and persistence of the CAR T cells and antigen-specific immune effectors in patients.

Combination of Alpelisib and Trametinib in Progressive Refractory Meningiomas
Aggressive growing meningiomas resistant to multiple surgeries and radiotherapy constitute an unmet pharmaceutical need in neurooncology, leading to a fatal issue within a few months. Grade II-III meningiomas progression-free survival (PFS) 6 is at 10-15%. Median PFS grade III meningioma is approximate 3 years. Alpelisib is a well-tolerated Phosphoinositide 3-kinase α (Pi3Kα) specific inhibitor. However, phosphatidylinositol-3-kinase (PI3K) and the mammalian target of rapamycin (mTOR) inhibition does not induce apoptosis in vitro and induces an antiproliferative effect without any radiologic response in most treated patients. Trametinib, a mekinist (MEK) inhibitor is currently...

Combination of Everolimus and 177Lu-DOTATATE in the Treatment of Grades 2 and 3 Refractory Meningioma: a Phase IIb Clinical Trial
Meningioma, the most common intracranial primary tumor of the central nervous system predominantly affects people in their fifties. Meningiomas are generally subdivided into two entities: a priori non-aggressive meningiomas (grade 1), and meningiomas at high risk of aggressive behavior (grade 2/atypical and 3/anaplastic). The current conventional treatments for meningioma are surgery and radiotherapy. When these treatments are no longer feasible, meningiomas are considered refractory irrespectively of grade, and in these rare entities, the therapeutic arsenal is reduced to the few treatments that have shown limited efficacy. Refractory, and particularly grades 2 and 3 meningiomas,...
