Not Yet Recruiting · Not Applicable · Hospices Civils de Lyon · registry updated 2026-06-01
Inclusion and exclusion lines below are quoted from ClinicalTrials.gov. No match score is shown, because a score needs a person's age, biomarkers, and treatment dates. Confirm the record with the study team.
With more than 3,000 new cases per year in France, malignant gliomas are the most common malignant brain tumors in adults. Treatment consists of surgical removal when possible. If this is not possible, a biopsy is performed to obtain a definitive anatomical and molecular diagnosis. Standard medical management after removal or biopsy is based on radio-chemotherapy. Despite this multimodal treatment, progression is the norm due to the invasive nature of these tumors. The prognosis remains very poor, with a median overall survival of around 18 months for glioblastomas. Recent preliminary data indicate that magnetoencephalography (MEG) recordings can identify functional heterogeneity within a glioma. Functional analysis of these two types of areas has shown that the expression of synaptogenic factors is increased in areas of high functional connectivity compared to areas of low functional connectivity. Areas of high functional connectivity are more aggressive and more resistant to treatment. In general, gliomas are characterized by a high degree of inter- and intra-tumoral heterogeneity....
