Glioblastoma Radiotherapy Using IMRT or Proton Beams
Radiation therapy is an integral part of the multimodal primary therapy of glioblastomas. As the overall prognosis in this tumor entity remains unfavorable, current research is focused on additional drug therapies, which are often accompanied by increases in toxicity. By using proton beams instead of photon beams, it is possible to protect large parts of the brain which are not affected by the tumor more effectively. An initial retrospective matched-pair analysis showed that this theoretical physical benefit is also clinically associated with a reduction in toxicity during therapy and in the first few months thereafter. The aim of the ...

Glioblastoma Remote Monitoring and Care - Research Protocol
The purpose of this research is to learn more about how what the Apple watch measures, in terms of walking data, heart rate, breathing rate, and sleep habits, relates to how participants feel. During the course of the treatment, the symptoms participants experience change, and whether the Apple watch can detect these changes. Ultimately, this knowledge is being used to design proactive tools and signatures that can predict complications or symptom changes before they happen.

Glioblastoma Targeted Treatment Option Maximization by WGS
In Dutch centers performing neurosurgery on and/or treating GBM, all recurrent GBM patients are discussed in local tumor boards and this setup will be used to effectively identify possible GLOW study candidates. 160 patients that will undergo re-resection in the GLOW study will be presented with WGS results leading to added treatment options.

Glutamate Excitotoxicity and Its Role in Glioblastoma Biology
Gliomas are the most frequent type of primary brain tumors in adults; among them glioblastoma multiforme (GBM) is the most malignant, being associated with the worst prognosis. Glutamate (Glu) is an aminoacid, responsible for essential functions in the Central Nervous System (CNS), acting both as metabolite and neurotransmitter. It is essential for regulating cellular metabolism and developmental synaptogenesis, cellular migration, differentiation and death. Recent scientific evidences have demonstrated alteration in Glu synthesis and signaling being directly involved in GBM growth and invasion

Glutamate Inhibitors in Glioblastoma
The goal of this 1:1 randomized, multi-center, open-label phase Ib/II clinical trial is to explore the efficacy of the add-on of the anti-glutamatergic drugs gabapentin, sulfasalazine and memantine to standard chemoradiotherapy with temozolomide compared to chemoradiotherapy alone in patients with newly diagnosed glioblastoma.

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.

GRETeL: Tumor Response to Standard Radiotherapy and TMZ Patients With GBM
The purpose of this study is to better define longitudinal genomic alterations in patients with glioblastoma (GBM), and to determine if plasma circulating tumor DNA (ctDNA) or cell free DNA (cfDNA) is associated with disease recurrence, survival, tumor characteristics, and/or peripheral immunosuppression.

Hierarchical Diagnosis for Adult Diffuse Glioma Based on Deep Learning
This is a restrospective study to establish a deep learning model based on multi-parametric magnetic resonance imaging scans to predict Grade, histopathologic type and genotype of adult diffuse Glioma.

Hitting the Mark: Introducing State-of-the-art MRI for Precision Radiotherapy of Glioblastoma
The goal of this prospective cohort study is to assess the potential of advanced MRI for improved radiotherapy target delineation in patients diagnosed with glioblastoma. The main questions it aims to answer are: - How does the coverage of the recurrence volume by a radiotherapy plan based on advanced MRI compare to the coverage by the clinical radiotherapy plan? - How does the distribution of the dose to organs at risk by a radiotherapy plan based on advanced MRI compare to the distribution by the clinical radiotherapy plan? Participants will undergo an extended MRI-protocol prior to radiotherapy. This...

hSTAR GBM (Hematopoetic Stem Cell (HPC) Rescue for GBM)
This phase II trial studies the effect of P140K MGMT hematopoietic stem cells, O6-benzylguanine, temozolomide, and carmustine in treating participants with supratentorial glioblastoma or gliosarcoma who have recently had surgery to remove most or all of the brain tumor (resected). Chemotherapy drugs, such as 6-benzylguanine, temozolomide, and carmustine, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing. Placing P140K MGMT, a gene that has been created in the laboratory into bone marrow making the bone more resistant to chemotherapy, allowing intra-patient dose...
