Filter by:Gliomas represent the most frequent primary brain tumor, with 2,500 to 3,000 new cases per year in France. Their diagnosis, although highly complex, is essential for determining patient management. While grade I gliomas (infrequent) are curable by surgery or present a slow progression, grades II to IV require heavy treatment (surgery and radio-chemotherapy), and are associated with a prognosis ranging from 10-15 years for grade II to only 15 months for glioblastoma. One of the key processes in glioma oncogenesis is the activation of a telomeric maintenance mechanism (TMM). Two TMMs ensure the maintenance of a telomere size compatible with intense cell proliferation (TERT mutation and ATRX loss). Liquid biopsy is used for the routine diagnosis and monitoring of treatment efficacy of different cancers. To date, no routine clinical testing of liquid biopsies is available for gliomas. The detection of glioma-specific oncogenic processes, by liquid biopsy, in peripheral blood (ctDNA) could improve diagnosis and follow-up and then avoid surgery for patients with suspected lesions. Three oncogenic markers can be used to detect gliomas: IDH mutation, TERT mutation, and a marker correlated with ATRX loss on total blood cells. We hypothesized that the circTeloDIAG will improve and accelerate the diagnostic/prognostic value of the actual classification and provide a new tool to manage patient response to treatment via liquid biopsy. It will combine detection of three markers in liquid biopsy, to produce a versatile tool for all types of gliomas. Patients with suspected newly diagnosed or recurrent glioma will be included.
Evaluate the diagnostic value of TERT promoter mutation in differ glioma subtypes and expend the application of the diagnostic algorithm to surgical practice
This is an open-label, multi-center, Phase 1/2 study of the brain-penetrant MEK inhibitor, mirdametinib (PD-0325901), in patients with pediatric low-grade glioma (pLGG).
In the last decades, many advances have been made in the field of genetic abnormalities of glial and glioneuronal brain tumors. In the 2016 World Health organization (WHO) Classification of Tumors of the Central Nervous System, the concept of "integrated" diagnosis emerged: histological and genetic/molecular features now define many entities. Since 2016, six updates have been published by the c-IMPACT-NOW (the Consortium to Inform Molecular and Practical Approaches to CNS Tumor Taxonomy- Not Official WHO) to develop and clarify the "integrated" diagnosis. In the future WHO 2021 Classification of Tumors of the Central Nervous System, "integrated" diagnoses will take up even more importance. Even if they can have similar histological features, gliomas of children are very different from the "adult" gliomas in the molecular mechanism of oncogenesis. The histomolecular features of adolescents/young adults (AYAs) can have similarities with "pediatric-type" or "adult-type" gliomas, but few studies have focused specifically on the histomolecular profiles of gliomas in AYAs. The investigators would like to study the cohort of patients treated for a glial and glioneuronal tumor diagnosed under the age of 25 in the Amiens University Hospital between 2008 and 2020. The investigators would like to compare the histomolecular profiles of gliomas in children (0-14 years) and AYAs (15-25 years).
Childhood aggressive gliomas are rare brain tumors with very poor prognosis. Due to the tumor's location and infiltrative nature, surgical removal is not always possible, and even when resection is performed and combined with chemo- and/or radiotherapy, tumor cells frequently persist, eventually giving rise to tumor recurrence. A promising strategy to eradicate persisting tumor cells is vaccination with dendritic cells (DC). DC are immune cells that play an important role in organizing the body's defense against cancer. The goal of DC vaccination is to activate these natural anti-tumor defense mechanisms to delay or prevent tumor progression or recurrence. Previous clinical studies have demonstrated that DC vaccination is well-tolerated, safe and capable of eliciting tumorspecific immunity. A clinical study including 10 pediatric patients (aged ≥ 12 months and < 18 years at the time of signing the informed consent) with brain (stem) tumors is initiated at the Antwerp University Hospital to investigate intradermal vaccination with WT1 mRNA-loaded autologous monocyte-derived DCs, either combined with first-line chemoradiation treatment or administered as adjuvant therapy following previous therapies. The general objective of this phase I/II clinical study is (1) to demonstrate that WT1-targeted DC vaccine production and administration in pediatric patients with HGG and DIPG, either combined with first-line chemoradiation treatment or administered as adjuvant therapy following previous therapies, is feasible and safe, (2) to study vaccine-induced immune responses, (3) to document patients' quality of life and clinical outcome for comparison with current patients' outcome allowing indication of the added value.
This trial studies how well spectroscopic magnetic resonance imaging (MRI) guided proton therapy works in assessing metabolic change in pediatric patients with brain tumors. The non-invasive imaging, such as spectroscopic MRI may help to map the differences in tumor metabolism compared to healthy tissue without injection of any contrast agent.
High-grade glioma is the most common primary malignant tumor in central nervous system, and its high tumor heterogeneity is the main cause of tumor progression, treatment resistance and recurrence. Habitat imaging is a segmentation technique by dividing tumor regions to characterize tumor heterogeneity based on tumor pathology, blood perfusion, molecular characteristics and other tumor biological features. In some studies, the Hemodynamic Multiparametric Tissue Signature (HTS) method has been proven to be feasible. The Hemodynamic Multiparametric Tissue Signature (HTS) consists of a set of vascular habitats obtained by Dynamic Susceptibility Weighted Contrast Enhanced Magnetic Resonance Imaging (DSC-MRI) of high-grade gliomas using a multiparametric unsupervised analysis method. This allowed them to automatically draw 4 reproducible vascular habitats (High-angiogenic enhancing tumor; Low-angiogenic enhancing tumor; Potentially tumor infiltrated peripheral edema; Vasogenic peripheral edema) which enable to describe the tumor vascular heterogeneity robustly. In other studies, contrast-enhancing mass can divided into spatial habitats by K-means clustering of voxel-wise apparent diffusion coefficient (ADC) and cerebral blood volume (CBV) values to observe the changes of voxels in spatial habitat on the time line. Using this so-called spatiotemporal habitat to identify progression or pseudoprogression in cancer therapy. Above all, we have sufficient and firm reasons to deem that habitat imaging based on multiparametric MRI is more conducive to reflect the potential biological information inside the tumor and realize individualized diagnosis and treatment. To sum up, the assumption of this experiment is that the Habitats Created by preoperative or postoperative Multiparametric MRI ,such as conventional MRI sequences, Dynamic Susceptibility Weighted Contrast Enhanced Magnetic Resonance Imaging (DSC-MRI), Dynamic Contrast Enhanced Magnetic Resonance Imaging (DCE-MRI), Diffusion Weighted Magnetic Resonance Imaging(DWI) ,Vessel Size Imaging (VSI) ,or Magnetic Resonance Spectroscopy (MRS) can predict the molecular mutation status, prognosis, treatment residence, progression, pseudoprogression, and even recurrence and distant intracranial recurrence in patients with high-grade gliomas.
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.
This phase 1 study will evaluate a novel hEGFRvIII-CD3-biscFv Bispecific T cell engager (BRiTE) in patients diagnosed with pathologically documented World Health Organization (WHO) grade 4 malignant glioma (MG) with an EGFRvIII (epidermal growth factor receptor variant III) mutation (either newly diagnosed or at first progression/recurrence). The primary objective is to evaluate the safety of BRiTE in such patients.
TTFields has been approved by the FDA for the treatment of patients with glioblastoma multiforme. However, the clinical effect and safety of radiotherapy concurrent of TTFields is not definite. In this study, the investigators conduct a phase II clinical trial to evaluate the efficacy and safety of this strategy.
