Filter by:This study is a clinical trial to assess the efficacy and confirm the safety of intratumoral inoculation of G207 (an experimental virus therapy) combined with a single 5 Gy dose of radiation in recurrent/progressive pediatric high-grade gliomas
This trial studies whether a customized video intervention can help to reduce anxiety in brain cancer patients undergoing radiation treatment and their caregivers. A customized neuro-imaging referenced symptom video that describes symptoms and side effects specific to the patients' tumor may result in an early and sustained reduction in anxiety and distress during and after radiation treatment, thereby improving quality of life.
The evaluation of gliomas in imaging represents a real challenge today, at the initial diagnosis, for therapeutic planning or follow-up treatment of these lesions. There is an urgent need for non-invasive imaging tools to evaluate a glioma throughout its management. At present, the diagnosis of certainty is only obtained through an anatomo-pathological analysis with sampling during an invasive procedure (surgery or biopsy). Magnetic resonance imaging, through perfusion, diffusion imaging or spectroscopy is developing in gliomas. However, it remains time-consuming and is not always available. At the same time, positron emission tomography (PET) with amino acids is an interesting alternative for these brain tumours. Amino acid PET has the advantage of being more specific than the abnormalities detected in MRI and the amino acid radiotracers cross the blood-brain barrier, even if not broken, unlike Gadolinium in MRI. Among these radiotracers, 18F-FDOPA can, among other things, assist in the non-invasive staging of gliomas at initial diagnosis.
Nutritional interventions such as ketogenic diet (KD) or fasting are currently under evaluation as anti-cancer treatment. In glioma patient cohorts, the feasibility and safety of fasting in addition to antitumor treatment has been shown. However, it is still unclear whether fasting exerts effects on the glioma tumor tissue at all, and whether fasting causes metabolic or immunological changes in the glioma microenvironment that could be exploited therapeutically. Therefore, the central contribution of this study is to characterize metabolic and immunological changes in the glioma tumor tissue induced by a fasting cycle of 72 hours prior to biopsy or resection.
From the medical records of a series of patients operated on for incident grade II and III glioma, the primary objective is to evaluate the correlation between the molecular profile of tumours and preoperative imaging data (by FDG and FDOPA PET-scan and multimodal MRI).
This Phase 2 study is conducted to assess the efficacy and safety of DS-1001b in patients with chemotherapy- and radiotherapy-naive IDH1 mutated WHO grade II glioma.
This is a prospective, single-arm, two stages, open-label, pilot study to investigate the efficacy and safety of FUS add-on bevacizumab (BEV) in rGBM patients. The BEV is the best physician's choice of standard of care for rGBM after prior radiotherapy and temozolomide chemotherapy in the LinKou Chang Gung Memorial Hospital. Eligible patients will be enrolled through the process of informed consent.
This study aimed to analyze the connectivity alterations in brain networks of LGG patients with epilepsy who take levetiracetam at short-term preoperatively.
This trial is an open-label, multicenter, Phase 0 trial that will enroll up to 20 participants with recurrent high-grade glioma with FGFR1 K656E or FGFR3 K650E mutation or FGFR3-TACC3 translocation which are scheduled for resection. In the lead-in cohort, a total of 20 participants will be enrolled into the proposed phase 0 clinical trial. Participants will be administered infigratinib prior to surgical resection of their tumor.
Background: Diffuse low-grade gliomas (DLGG) are slow-growing primary-cancer of the brain and spinal cord. They represent up to 15% of the developing tumors in those organs with fatal outcome for the patients because of their evolution. The reasons for this transformation towards more malignant tumors still remain ill defined. Previously, the research team in neuro oncology at Montpellier University Hospital found foci of tumor heterogeneity within 20 to 30 % of the patients developing a DLGG and published their results. The investigators assumed that those foci represent the early beginning of the transformation from a diffuse low-grade glioma to a glioblastoma, tumor with highly malignant cells and a life expectancy of two years in average for the patient. Methods: The investigators selected adult patients with no prior surgery nor neuro oncology treatment when enrolled. They presented a specific mutation for an enzyme of the metabolism named IDH1, standing for Isocitrate Dehydrogenase 1, found in 70% of DLGG. Patients were also selected because they presented foci of tumor heterogeneity. After obtaining their consent, the investigators studied by immunohistochemistry the pathways deregulated between the DLGG and the foci. The investigators also extracted RNAs, molecules expressing the life and metabolism of tumor cells, and compared them to know what genes were differentially expressed between the DLGG and the foci. All RNAs were tested for quality control prior to be processed further. The investigators then studied 8 patients with compliance with ethics, authorizations and institutional guidelines. Genes of interest were studied in vitro to assess their functions. The investigators found a barely described enzyme of the catabolism of the phosphoethanolamines and discovered a new anti-proliferative tumor-role for it. •Discussion: The investigators first showed that foci have a higher percentage of p-STAT3+ cells which indicates STAT3 pathway activation in these cells. Phosphorylated STAT3 translocates to the cell nucleus to regulate many genes involved in proliferation, apoptosis and angiogenesis. As such, phosphorylation of STAT proteins, notably STAT3, is involved in the pathogenesis of many cancers, including GBM, by promoting cell cycle progression, stimulating angiogenesis, and impairing tumor immune surveillance. The investigators found that ETNPPL RNA and protein are reduced in foci cells and absent in glioblastomas. This is consistent with glioma database analyses showing that ETNPLL expression is inversely correlated to STAT3 and MKI67 whose expression are higher in foci and glioblastomas. In addition, Kaplan-Meier analysis shows that patients with low expression of ETNPPL have lower overall survival These observations suggested that this enzyme may oppose glioma cells proliferation. The investigators demonstrated this hypothesis by overexpressing ETNPPL in 3 glioblastoma cell cultures. Two were sensitive to ETNPPL overexpression which reduced their growth while no effect was detected in Gli4 cells. These glioblastoma-derived cultures have different types of mutations.
