FDG and FDOPA PET Demonstration of Functional Brain Abnormalities
The purpose of this pilot study will be to conduct a clinical trial using a time-of-flight PET scanner and MRI scanner to test an improved method for differentiating tumor recurrence from radiation necrosis in glioblastoma patients. We will attempt to do so by performing a static and dynamic FDG-PET scan, a static and dynamic FDOPA-PET scan, and a multiparametric MRI scan - then comparing the results with surgical pathology and static FDG-PET scans. We hypothesize that the new quantitative kinetic analytical methods using FDOPA in combination with FDG will provide crucial functional information to distinguish recurrent tumors from treatment-induced radiation changes in patients...

Feasibility of Quality of Life Assessment in Routine Clinical Oncology Practice at the University Hospital of Besancon
Symptoms related to the disease and/or treatment are common in cancer patients and can affect patient health-related quality of life (HRQol). Unfortunately these symptoms can be underestimated and underreported by the physician. Measure of the HRQoL has been significantly developed in clinical trials and has become a key endpoint to assess clinical benefit of new therapeutic strategies and as prognostic factor of overall survival for several cancer as in women breast cancer, glioblastomas, metastatic colorectal cancer, prostate cancer and hepatocellular carcinoma. Moreover, a recent study conducted in patients receiving routine outpatient chemotherapy for advanced solid tumors...

Feasibility Study of 68Ga-PSMA PET-CT and 18F-FDOPA PET-CT in Glioblastoma's Patients
This study is a non-randomized, prospective, multicentric feasibility study assessing 68Ga-PSMA PET-CT and 18F-FDOPA PET-CT to differentiate early recurrence from post-radiation modifications in patients treated with radiotherapy for glioblastoma. Patients with a MRI performed since the end of the radiotherapy until 12 months of follow up after the end of radiotherapy, will be referred for both 68Ga-PSMA and 18F-FDOPA PET-CT, whatever the conclusion of the MRI (post radiation modifications, relapse or doubtful MRI). The rationale of doing 68Ga-PSMA and 18F-FDOPA brain PET-CT in each case will be discussed in detail with the referring physician and an informed consent will be...

FET-PET and Multiparametric MRI for High-grade Glioma Patients Undergoing Radiotherapy
Glioblastoma is the most common malignant brain tumor in adults. The primary treatment consists of maximal tumor removal followed by radiotherapy (RT) with concomitant and adjuvant temozolomide. Tumor recurrence after chemoradiotherapy has previously been shown to be predominantly within or at the margin of the irradiated volume, but distant failure are not rare, especially in patients with MGMT methylation.Traditionally, RT has been planned based on on planning CT with co-registered postoperative MRI, with the addition of a clinical target volume margin of 2-3 cm to account for infiltrative odema. To better characterize the disease, more specific physiological and/or...

Fluorescence, Light-microscopy, Ultrasound Integrated / Intraoperative Diagnosis to MAXimise Resection
The present study aims to evaluate and compare with the histopathological analysis the various margin-assessment systems, including ultrasound, florescence, brightfield vision, new optical filters and microscope image post-processing systems, for the treatment of High Grade Gliomas (HGGs)

Glioblastoma Evaluation for Heterogeneity In RadioseNsitivity
This is an observational study on GBM surgical samples to investigate if increasing doses of radiation therapy could improve the radiation response; and in particular the investigators will assess if there is a correlation between the number of the phosphorylated H2AX nuclear foci and the different dose level of radiation therapy.

Glioblastoma: Validation and Comparison Between Primary Tumor and Its Murine Model
Despite maximal safe surgery followed by combined chemo-radiation therapy, the outcome of patients suffering from glioblastoma (GBM) remains extremely poor with a median survival of 15 months. Hence, new avenues have to be taken to improve outcome in this devastating disease. Given their intracerebral localization and their highly invasive features, GBM pose some specific challenges for the development of adequate tumor models. Orthotopic xenograft models directly derived from the tumor of a patient might represent an attractive perspective to develop patient-specific targeted therapies. This approach remains however to be validated for GBM as it offers specific challenges,...

Grafts of GSCs Into Brain Organoids for Testing Anti-invasion Drugs
In patients operated for glioblastoma, glioma stem-like cell lines will be obtained from tumor tissue, and IPSCs from skin fibroblasts or PBMCs. Brain organoids will be generated from IPSCs and co-cultured with IPSCs to study brain invasion and ciliogenesis. 3D genome architecture of glioma stem-like cells will be investigated. Gene modulation and pharmacologic strategies to inhibit invasion and restore ciliogenesis will be explored.

Gut Microbiota and Glioblastoma Multiforme Prognosis
Glioma is the most common primary cancer of the central nervous system, and around 50% of patients present with the most aggressive form of the disease, glioblastoma. Conventional therapies, including surgery, radiotherapy, and pharmacotherapy (typically chemotherapy with temozolomide), have not resulted in major improvements in the survival outcomes with only a median survival of around 15 months.The main reason may be related to the highly immunosuppressive tumor microenvironment. In recent years, the microbiome has emerged as a key regulator of not only systemic immune regulation but brain circuitry, neuro-physiology and microglia development. We hypothesized that there is a...

HMPL-813 in Treating Patients With Glioblastoma
This is an open-label study, to evaluated epitinib, which is a selective epidermal growth factor receptor tyrosine kinase inhibitor (EGFR TKI), to treat glioblastoma patients with EGFR gene amplification. As epitinib could cross blood-brain barrier (BBB), inhibition of EGFR may provide a novel mechanism in treating glioblastoma.
