  • 1

    CNS tumors, particularly gliomas, pose significant diagnostic challenges due to their heterogeneity and evolving classification criteria.

  • 2

    The WHO classifications of CNS tumors have progressively integrated molecular markers, enhancing diagnostic accuracy but complicating tumor characterization.

  • 3

    In resource-limited countries, limited access to molecular testing hinders the full application of WHO classification criteria for gliomas.

  • 4

    A retrospective study at a Latin American neurosurgical center revealed increased cases of incomplete tumor characterization with newer WHO classifications.

  • 5

    The reliance on external laboratories for molecular testing in developing regions delays diagnoses and negatively impacts treatment decisions.
