MRI Following Stereotactic Radiosurgery (SRS) for Brain Metastases
The purpose of this study is to test whether an additional magnetic resonance image (MRI) sequence can improve the ability to distinguish radiation damage from tumor recurrence in participants with brain metastasis who have previously been treated with stereotactic radiosurgery (SRS).

MRI Guided Radiotherapy and Radiobiological Data: the ISRAR Database (Irm Sequences for Radiobiological Adaptative Radiotherapy)
The MRI linac Unity is a major technological evolution in radiotherapy combining a linear accelerator with a 1.5T MRI (radiological quality). It allows to target the target volume more precisely and to adapt the daily dose distribution according to variations in the position and volume of the tumor, critical organs and the tumor response. In many studies conducted in radiology, the analysis of specific MRI sequences, particularly in radiomics, aims to characterize tumors and their sensitivity to treatment. Initial data show that in radiotherapy, it would eventually be possible to characterize the radiosensitivity of healthy and tumorous tissues. With linac 1.5T MRI, the performance...

MRI in High-Grade Glioma Patients Undergoing Chemoradiation
The purpose of this research study is to see if investigators can predict how brain functioning changes after radiation treatment based on PET scans and blood tests. Most participants experience at least mild decreases in their memory or attention after radiation therapy. Investigators hope that PET scans, lumbar puncture, and blood tests might help investigators predict who might have larger changes in their brain function after radiation.

MRI Screening for Brain Metastases Among Patients With Triple Negative or HER2+ Stage II or III Breast Cancer
The goal of this multi-centre, prospective study is to assess the frequency of asymptomatic brain metastasis in patients with stage II or III Triple Negative or HER2 positive breast cancer. The main questions it aims to answer are: 1. What proportion of patients with stage II or III Triple Negative or HER2 positive breast cancer have asymptomatic brain metastases identified on a screening contrast-enhanced magnetic resonance imaging (or computed tomography when Magnetic resonance is not possible) of the brain? 2. How do patients feel about undergoing brain imaging to screen for asymptomatic Brain metastasis? 3. What clinical and tissue-based...

MRS of Glioma Genomics
In France, about 5000 new people with a primary malignant brain tumor are diagnosed each year. The most common primary tumors are gliomas, originating from glial cells (astrocytomas and oligodendrogliomas). Low-grade gliomas are mildly aggressive, but they often evolve into a more malignant form. Mutations in the genes encoding isocitrate dehydrogenase (IDH) are found in about 80% of low-grade gliomas and are associated with a favorable prognosis. Remarkably, IDH-mutated gliomas are characterized by a specific cellular metabolism causing the accumulation of D-2-hydroxyglutarate (2HG) in tumor cells. 2HG can be detected in vivo using 1H magnetic resonance spectroscopy (MRS) and...

MSC-DNX-2401 in Treating Patients With Recurrent High-Grade Glioma
This phase I trial studies best dose and side effects of oncolytic adenovirus DNX-2401 in treating patients with high-grade glioma that has come back (recurrent). Oncolytic adenovirus DNX-2401 is made from the common cold virus that has been changed in the laboratory to make it less likely to cause an infection (such as a cold). The virus is also changed to target brain cancer cells and attack them.

Multi-antigen T Cell Infusion Against Neuro-oncologic Disease
This Phase I dose-escalation trial is designed to determine the safety and feasibility of rapidly generated tumor multi-antigen associated specific cytotoxic T lymphocytes (TAA-T) in patients with newly diagnosed diffuse intrinsic pontine gliomas DIPGs (Group A) or recurrent, progressive, or refractory non-brainstem CNS malignancies (Group B). Pediatric and adult patients who have high-risk CNS tumors known to typically have positivity for one or more Tumor Antigen Associated (TAA) (WT1, PRAME and/or Survivin) will be eligible. TAA-T will all be generated from patient peripheral blood mononuclear cells (PBMC). Group A patients (DIPG): The first TAA-T dose will be infused any...

Multicenter Pheochromocytoma and Paraganglioma Evaluation
Target population: Patients with (1) newly diagnosed or (2) past history of pheochromocytomas and paragangliomas (PPGL) or (3) carrier of genetic mutations in known PPGL susceptibility genes. International multicenter prospective cohort study with randomized intervention (special care follow-up vs. standard care follow-up). All patients will receive instructions about follow-up at the time point of study inclusion. Patients randomized to the standard care follow-up group will be advised to return annually for follow-up according to current routine practice (without active re-scheduling). In contrast, patients randomized to the special care follow-up group will also be...

Multicenter Registry for Patients With Childhood.Onset Craniopharyngioma, Xanthogranuloma, Cysts of Rathke's Pouch, Meningioma, Pituitary Adenoma, Arachnoid Cysts
KRANIOPHARYNGEOM Registry 2019 will prospectively collect and descriptively analyse data on diagnostics, treatment, and follow-up of patients with craniopharyngioma. In continuation of preceding studies also patients with xanthogranuloma, meningioma, pituitary adenoma, prolactinoma and cystic intracranial malformations will be registered.
