Filter by:This single center, single arm, open-label, phase 2 study will assess the safety and efficacy of a pedicled temporoparietal fascial (TPF) or pericranial flap into the resection cavity of newly diagnosed glioblastoma multifome (GBM) patients. The objective of the Phase 2 study is to demonstrate that this surgical technique is safe and effective in a human cohort of patients with resected newly diagnosed AA or GBM and may improve progression-free survival (PFS) and overall survival (OS).
The aim of this study was to analyse usefulness of [68Ga]Ga-PSMA-11 PET/CT scans in preoperative differentiation between HGG and LGG in patients with suspicion of a tumor of glial origin in previously performed imaging examinations. The PET/CT scan will be compared with postoperative histopathological results and with additional immunohistochemical staining for PSMA expression.
This retrospective study aims to assess the utility of 2D non-navigated intraoperative ultrasound (ioUS) as a cost-effective alternative for guiding the surgical resection of gliomas and for detecting residual tumor. The study will analyse the records from consecutive adult patients diagnosed with gliomas, undergoing craniotomy between June 2018 and June 2023. The extent of resection (EOR) will be determined using postoperative MRI as the gold standard. The study will also examine the sensitivity and specificity of ioUS in detecting residual tumor. This research seeks to determine if ioUS can be an affordable and reliable tool that, combined with other intraoperative adjuncts, may aid neurosurgeons in achieving the maximum safe resection in glioma surgery.
The goal of this observational study is to evaluate disease-free survival (DFS) in patients with malignant gliomas undergoing neurosurgical procedures using 5-aminolevulinic acid (5-ALA)-based photodynamic therapy
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.
This is a single-center, open-label, dose-escalating Phase 0 trial that will enroll participants with a confirmed diagnosed recurrent high-grade glioma (grade 3 or 4 per WHO criteria) targeting the mTOR pathway. Eligible participants will be administered a single infusion of temsirolimus through super-selective intra-arterial infusion or intravenous infusion. Participants will receive the study drug administration on the same day as the planned surgical resection of the tumor.
The study aims at investigating the cilium-related transcriptome in patients-derived glioblastoma stem cells and the potential impact of modulation of cilium players in vitro, in vivo and ex vivo in glioblastoma brain organoids. Moreover, drugs inhibiting cilia disassembly will be tested. Finally, the potential prognostic role of a cilium-related gene expression signature in glioblastoma will be assessed.
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.
Patients with gliomas often suffer from lower quality of life, and detrimental social interactions after diagnosis. Two cognitive processes are crucial for maintaining healthy social relationships and interacting with others: social cognition and language. Social cognition is the ability to recognize and process mental and emotional states and to react appropriately in social situations. Social cognition and language are separate cognitive functions that can be affected in different ways in patients with brain injury. Also, distinct cognitive measurement instruments are used to assess both processes. However, there appears to be a certain overlap between social cognition and language. Reacting adequately in social situations requires both verbal and non-verbal communication and to communicate feelings, thoughts and intentions, people often use language. That is, verbal communication is part of a symbolic system that makes social interaction possible. Therefore, language abilities seem to be important to social cognition. Research shows that language is frequently impaired in adult patients with gliomas. Importantly, recent evidence suggests that social cognition can also be impaired in this patient group. However, no studies have been conducted into the relationship between social cognition and language in patients with gliomas. Increasing knowledge on the overlap between both functions, more specifically the influence of language difficulties on social cognition, will improve diagnostic accuracy. Eventually, this will lead to better, tailor-made treatments for these problems that negatively affect daily functioning. Objective: The main research objective is to examine the influence of language impairments on different social cognition processes, i.e., emotion recognition, Theory of Mind (ToM) and affective empathy, in patients with (suspected) gliomas. Secondary objectives are 1) to determine if patients with gliomas show impairments in different aspects of social cognition, i.e. emotion recognition, ToM, empathy and self-awareness; 2) to assess specific language impairments by looking at item-level characteristics of language tasks (e.g., analyses of word properties of fluency tasks, errors during object naming or spontaneous speech), and 3) to determine which tumor characteristics (low- or high-grade, genetic mutation, tumor location) are associated with different aspects of language and social cognition.
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.
