Filter by:Patient education plays an essential role in patient-centered care as it enhances patient satisfaction and information comprehension. However, about 40-80% of the information patients receive from healthcare professionals is forgotten and about half of the information patients remember is incorrect. To give informed consent, patients must be able to understand and recall the discussed information correctly. This is especially important in brain tumor patients, in which different treatment options determine outcome and risks. The goal of treatment in brain tumors is resection as completely as possible, without damaging healthy brain tissue. To this end, patients must understand the complex relation of the tumor to healthy brain tissue. This relation is different in each patient and three-dimensional (3D) in nature. Current two-dimensional visual tools lack the ability to properly display these complex 3D relations. In this study, we will investigate the effect of the use of 3D models in patient education, taking into account patient specific factors that might act as confounders. We will conduct a case control, multi-center study in the Radboud University Medical Center (Radboudumc) Maastricht University Medical Center (MUMC). Patients will be enrolled in the control group until inclusion for the control group is completed (n=30), after which patients will be enrolled in the intervention group (n=30). Patients will be cognitively tested using the Amsterdam Cognition Scale (ACS). After the consultation with their neurosurgeon, patients will be asked to fill out two questionnaires, consisting of two parts (patient experiences and information recall), one week apart.
The prognostic value of ANXA2 expression in tumor tissue and PTBE was analyzed, so as to seek new therapies to inhibit glioma invasion and improve the prognosis of glioma patients
This study is to investigate the safety and efficacy of tumor infiltrating lymphocyte (TIL) therapy in patients with malignant glioma . Autologous TILs are expanded from tumor resections and infused i.v. into the patient after NMA lymphodepletion treatment with hydroxychloroquine(600mg,single-dose) and cyclophosphamide.
This is a phase I, open label, plus expansion clinical trial evaluating the safety and tolerability of rHSC-DIPGVax in combination with BALSTILIMAB and ZALIFRELIMAB. rHSC-DIPGVax is an off-the-shelf neo-antigen heat shock protein containing 16 peptides reflecting neo-epitopes found in the majority of DIPG and DMG tumors. Newly diagnosed patients with DIPG and DMG who have completed radiation six to ten weeks prior to enrollment are eligible.
A single-arm, single-center, open-labeled study will be conducted with an aim to investigate the feasibility, safety, and efficacy of the personalized vaccine for patients with recurrent malignant glioma.
This Phase 0 surgical window of opportunity trial seeks to evaluate the pharmacokinetic (PK) and pharmacodynamic (PD) properties of an FDA-approved proprotein convertase/ kexin type 9 serine protease inhibitor (PCSK9i) in patients with primary and recurrent World Health Organization (WHO) grade IV malignant glioma. The investigators intend to evaluate whether a clinically licensed PCSK9i called evolocumab (also known as Repatha) can be repurposed as a potential immunotherapeutic for high grade glioma by testing its ability to access the intracranial space. The primary objective is to evaluate whether evolocumab crosses the blood brain barrier (BBB) and is measurable in the resected tumor specimens of patients with primary and recurrent high grade glioma or glioblastoma.
Fluorescence-guided resection using 5-ALA induced tumor fluorescence of malignant gliomas allows for better identification of tumor tissue and more radical resection in select patients and improvements in progression-free and overall survival. With new developments in surgical microscopy, the development of digital exoscopes have provided advanced visualization as well as improvements in ergonomics and accessibility of the surgical field. The use of the exoscope in 5-ALA fluorescence-guided tumor surgery has the potential to enhance the ability of the surgeon to remove brain tumors with high efficacy. While algorithms for use of 5-ALA fluorescence have been optimized for use with traditional microscopes, the use of fluorescence techniques in newer digital exoscopes have not been developed. The primary outcome of the study is to obtain parameters to optimize visualization of fluorescence intensity and perform optimization based on the intensities achieved. The operating ORBEYE exoscope will be fitted with a blue light filter. All experiments will be performed in darkened operating rooms. The ORBEYE exoscope will be set up at constant distances from the target and incident light intensities. The focal distance and light intensity settings will be recorded from the data displayed on the microscope. Patients (experimental group) will receive 5ALA treatment before operation, blue light filter imagining will take place after tacking up dura and prior to direct resection. The expected outcomes of image analysis will be to have a set of exoscope parameters optimized for visualization of 5ALA tissue in different tumor types. This 5ALA characterization of visualization parameters has never been completed on an exoscope. Optimizing ORBEYE exoscope parameters will define a standard in glioma resection using 5ALA under a novel exoscopic filter as well as contribute insight into the use of the fluorescent filter for additional tumor types.
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.
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).
