  • To highlight the potential of future genomic and gene expression research.

Main Methods:

  • Review of historical genetic research in glioma.
  • Description of current molecular genetic techniques for brain tumor classification.
  • Discussion of genome-level and gene expression analysis.

Main Results:

  • Identification of three distinct developmental types of glioblastoma multiforme using genetic markers.
  • Ability to predict patient response to alkylating cytostatic drugs based on genetic profiles.
  • Established the foundation for future research directions.

Conclusions:

  • Genetic molecular techniques have revolutionized the understanding and classification of glial brain neoplasms.
  • Future research focusing on gene expression will likely lead to improved tumor grading and personalized treatment strategies.
  • Genomic and transcriptomic analyses offer new therapeutic targets for brain tumors.
