Filter by:cephaloceles are rare lesions of the petrous apex, inconsistently listed as meningoceles or arachnoid cysts. They're consistent with a herniation posterolateral of the Meckel cavum within the petrous apex. These lesions may be the cause of a symptomatology varied, or be discovered by chance in subjects who have not been asymptomatic. Currently, there is no evidence in the literature a simple, fast and reproducible radiological marker that allows for the diagnosis of cephaloceles of the petrous apex, in particular the small ones. The purpose of this study is to validate a radiological benchmark simple and reproducible, the trigeminal petrol line, in order to improve the diagnosis of petrous apex cephaloceles
The general objective of this project is to evaluate the value of cell-free DNA circulating in plasma as a marker of tumor evolution in patients with high-grade gliomas and meningiomas. To this end, we propose to longitudinally collect four samples of plasma at the following time points: - T0: before surgery; - T1: one month after surgery; - T2: one month after the end of radiotherapy; - T3 at the time of radiological progression. The goal is to evaluate whether changes in plasma concentration of circulating cell-free DNA can help predict progression-free survival, overall survival, and response to therapies.
In this proposal, the investigators introduce a novel, translational study to prospectively examine primary brain tumor patients undergoing fractionated radiation therapy to the brain. Quantitative neuroimaging, radiation dose information, and directed neurocognitive testing will be acquired through this study to improve understanding of cognitive changes associated with radiation dosage to non-targeted tissue, and will provide the basis for evidence-based cognitive- sparing brain radiotherapy.
Tumor dosimetry with somatostatin receptor-targeted peptide receptor radionuclide therapy (SSTR-targeted PRRT) by 177Lutetium-DOTATATE might contribute to improve follow-up and treatment response of refractory meningiomas. This study aims to evaluate Standard Uptake Value mean (SUVmean) as a tumoral absorbed dose predictive predictive factor and propose semi-automated segmentation method to determine metabolic tumor volume with pretherapeutic 68-Gallium-DOTATOC PET.
A Phase II Study of Cabozantinib for Patients with Recurrent or Progressive Meningioma
The natural course for meningioma suggests that a majority will grow over time. Treatment is usually indicated in growing or symptomatic meningiomas. Surgery is usually primary treatment, but there is a significant risk of adverse effects. Stereotactic radiotherapy is most often reserved to treat relapses after surgery, and except for surgery and radiotherapy there are no other established treatment methods. Endovascular embolization may be used in selected cases as a preoperative adjunct to reduce intraoperative bleeding. There is a need for more treatment options in patients with meningioma, both in uncomplicated, asymptomatic cases and in more complex cases. The aim of this study is to assess radiological and clinical results of therapeutic endovascular embolization for meningioma
The purpose of the proposed study is to investigate the usefulness of laser speckle contrast imaging (LSCI) compared to indocyanine green angiography (ICGA). We will collect data from a wide variety of neurovascular surgical procedures to determine when the technology is the most clinically useful. The intraoperative LSCI system provides high resolution images of blood flow in real-time without tissue contact and without the need for an exogenous contrast agent. Further study is needed to gain a better understanding of the use of the technique during surgery, but initial results suggest that the ability to identify blood flow changes with immediate feedback to the surgeon could be a significant advantage during many procedures.
This study will evaluate the safety and efficacy of Lutathera (177Lu-DOTATATE) in patients with progressive or recurrent High-Grade Central Nervous System (CNS) tumors and meningiomas that demonstrate uptake on DOTATATE PET. The drug will be given intravenously once every 8 weeks for a total of up to 4 doses over 8 months in patients aged 4-12 years (Phase I) or older than 12 yrs (Phase II) to test its safety and efficacy, respectively.

Determine by a transcriptomic approach new prognostic and predictive markers in atypical meningiomas (WHO grade II). Retrospective observational study, on a cohort of 85 atypical meningiomas. Transcriptomic study first, on cryopreserved tumor samples. Then identify, thanks to the transcriptomic study, prognostic and predictive factors (study of the link between the quantity of certain RNA transcripts and progression-free survival). Finally, set up immunohistochemical applications, which can be used routinely by the pathologist.
The registry of this study was subjected to patients who were radiologically diagnosed with a non-malignant brain tumor at Seoul National University Hospital since 2001, and who have had magnetic resonance (MR) re-examination after first MR exam or will be re-examined because it was determined that immediate treatment would not be needed at the first visit to the hospital. In all MRs taken by patients, the date of imaging and the volume of the tumor are measured, and we aim to establish a natural growth history for non-malignant brain tumors.
