Epidemiological analysis of adult-type diffuse lower-grade gliomas and incidence and prevalence estimates of diffuse IDH-mutant gliomas in France.
Background: The recent advent of anti-IDH therapies and changes in the WHO classification of gliomas implies estimating the number of patients who could benefit (or not) from anti-IDH treatment. As published data on the current incidence of different subtypes of IDH-mutant gliomas (based on the latest histomolecular WHO classification) are lacking in many countries. The present analysis aims to review the main factors impacting the incidence of gliomas and lower-grade gliomas and to estimate the incidence and prevalence of IDH-mutant gliomas in France.
Methods: Our analysis was based on data from the French Brain Tumor DataBase and literature.
Results: Case definition, recording methods, histological classifications, age, sex, ethnicity, ancestry, environment, genetics, etc., impact the incidence of gliomas overall and lower-grade gliomas. In France, for the year 2024, the incidence estimates of all gliomas and all adult-type diffuse IDH-mutant gliomas are 6.6/100,000 and 1/100,000 person-years, respectively. The incidence estimates of grades 2, 3, and 4 diffuse IDH-mutant gliomas are 0.5, 0.3, 0.2 per 100,000 person-years, respectively. Of note, the incidence estimate of grade 3 diffuse IDH-mutant glioma versus grade 2 or 4 is slightly more difficult to assess due to the possible variability in histological criteria to define tumor grade. The prevalence of diffuse IDH-mutant grade 2 glioma would be more than 6.57/100,000 persons.
Discussion/conclusion: Our epidemiological analysis provides estimates of potential number of patients, but large prospective real-world studies are required to determine the positioning of anti-IDH treatments among all therapeutic strategies [surgery(ies), chemotherapy(ies), radiotherapy(ies), clinical/radiological follow-up, etc.].
期刊介绍：
Neurochirurgie publishes articles on treatment, teaching and research, neurosurgery training and the professional aspects of our discipline, and also the history and progress of neurosurgery. It focuses on pathologies of the head, spine and central and peripheral nervous systems and their vascularization. All aspects of the specialty are dealt with: trauma, tumor, degenerative disease, infection, vascular pathology, and radiosurgery, and pediatrics. Transversal studies are also welcome: neuroanatomy, neurophysiology, neurology, neuropediatrics, psychiatry, neuropsychology, physical medicine and neurologic rehabilitation, neuro-anesthesia, neurologic intensive care, neuroradiology, functional exploration, neuropathology, neuro-ophthalmology, otoneurology, maxillofacial surgery, neuro-endocrinology and spine surgery. Technical and methodological aspects are also taken onboard: diagnostic and therapeutic techniques, methods for assessing results, epidemiology, surgical, interventional and radiological techniques, simulations and pathophysiological hypotheses, and educational tools. The editorial board may refuse submissions that fail to meet the journal''s aims and scope; such studies will not be peer-reviewed, and the editor in chief will promptly inform the corresponding author, so as not to delay submission to a more suitable journal.
With a view to attracting an international audience of both readers and writers, Neurochirurgie especially welcomes articles in English, and gives priority to original studies. Other kinds of article - reviews, case reports, technical notes and meta-analyses - are equally published.
Every year, a special edition is dedicated to the topic selected by the French Society of Neurosurgery for its annual report.
