Active clinical trials for "Glioma"

WHO classification of low grade gliomas now relies on tumoral molecular patterns, especially on IDH mutation and 1p/19q co deletion status. Textural analysis on medical imaging is studied in several fields, and could provide help in patients with brain tumor due to possible complications of brain biopsy. The purpose of this study is to determine if specific textural signature on MR imaging could be found for low grade gliomas. The investigators included patients with LGG diagnosed at CHU of Nice abd whose first MRI was available on the PACS of the CHU. Textural data are extraxted by tumoral contouring and specific logiciel (LifeX) and histopathologic data are assessed for each patient. Then the investigators analyze it to dtermine if textural indices can predict molecar status.

There is limited knowledge regarding the quality of life and needs of patients with advanced high grade gliomas, especially during the end of life. By doing this research, we are able to assess caregiver and patient symptoms and needs during the end of life phase of patients with brain tumors.

We explores the accuracy and sensitivity of rapid intraoperative detection of IDH, TERT, BRAF indicators through a prospective clinical multi-center study. This part includes a total of 300 fresh tissue samples, paired blood samples, relevant clinical information and follow-up information from 300 patients with different grades of adult glioma. By comparing with the postoperative sequencing results, the specificity and sensitivity of intraoperative IDH and TERT rapid detection results are clear.

Retrospective longitudinal follow-up in patients with diffuse low-grade glioma with multimodal MRI assessment

In this study, we evaluate the role of diffusion kurtosis imaging (DKI) and MR spectroscopy (MRS), two advanced imaging techniques in magnetic resonance (MR) in grading and detection of microscopic infiltrating tumour in gliomas. These parameters are of utmost importance in optimal choice and planning of treatment. Patients treated with gliomatous brain tumours are included voluntarily. They undergo one imaging session on a 3T MR scanner prior to treatment. DKI data are quantitively analyzed in order to estimate specific parameters in normal appearing white matter, grey matter, tumor and peritumoral edema. MRS data are analyzed quantitatively and qualitatively with peak integration, ratio calculation and classification algorithms. Histological confirmation is obtained at subsequent surgery. Information from this study can be of significant importance in avoiding brain biopsies. Furthermore, information on microscopic tumour spread can be used during neurosurgery or in radiotherapy planning. An important advantage of these advanced MR techniques is the non-invasivity and the lack of ionizing radiation, two important issues in this relatively young patient population.

Main limitations in Glioma studies are due to the wide heterogeneity and genetic instability of the tumor and to the fact that the molecular informations are static, i.e. obtained on the tumor at its onset. Instead, spontaneous or therapy-induced variations are difficult to evaluate and they would need further sampling of the tumor throughout the clinical history. Currently these data are more and more routinely used not only for diagnostics but also in the clinical management of the patient. Furthermore, microenvironment study is becoming increasingly important. It is also important correlate morpho-functional pathway and brain Magnetic Resonance. Therefore, the main goal of the study is to correlate the data obtained with morphological (site, signal intensity, margins, behavior after contrast medium infusion, mismatch between T2 and FLAIR sequences) and non-morphological MR imaging through a radiomic approach and Diffusion and Perfusion study, with molecular data relating to the IDH mutation, MGMT gene promoter methylation, 1p/19q co-deletion and EGFRvIII expression. Furthermore, it is proposed to carry out a correlation between the radiological data and the mutations found in the NGS panel.

Glioma is the most common primary malignant brain tumour in adults and has an extremely poor prognosis. The aim of this study is to quantify the degree of early step fatty acid oxidation in gliomas as imaged by 18F-FPIA PET/MRI in 10 evaluable patients. The Investigators hypothesise that FPIA uptake will be higher in high-grade gliomas compared to lower grade gliomas, in keeping with a higher propensity of high grade tumours to generate ATP and NADPH via fatty acid oxidation under bioenergetic stress.

This is an expanded access program to provide vorasidenib for treatment of patients 12 years or older with IDH1- or IDH2-mutated glioma.

Background : The supplementary motor area is the most common/preferential brain location of LGG. This area plays an important role in many motor and cognitive functions such as motor initiation, bimanual coordination and executive functions. Many studies describe the supplementary motor area syndrome resulting from lesions in this area. News managements for LGGs consisting in intraoperative mapping in awake patients reduce significantly neurological disorders and increase also the overall survival . However, the literature does not provide data concerning motor and cognitive functions in a long term and their consequences in the quality of life of patients. Objective : The aim of our research project is to identify whether there are some motor or neurocognitive deficit in the short and the long term in a population of patients who have medical story of LGG resection in the supplementary motor area.

the study aim to evaluate the prevalence of cerebral remote microhaemorrhages (RMH) and remote haematomas (RH) using magnetic resonance susceptibility-weighted imaging (SWI) among patients treated for gliomas during follow-up.
