Overview

Glioblastoma multiforme may be classified into several subtypes based on the origin (primary and secondary) and molecular alterations (classic, proneural, mesenchymal, and neural).[1][2]

Classification

Based on the origin

Glioblastoma multiforme may be classified according to the origin into two subtypes: Primary and secondary.[1]

Subtype of Glioblastoma multiforme Characteristic features
Primary glioblastoma multiforme
  • De novo origin
  • More aggressive
  • Occurs in older patients
Secondary glioblastoma multiforme
  • Arises from pre-existing lower grade gliomas
  • Less aggressive
  • Occurs in younger patients
  • Primary and secondary forms show some molecular differences.
  • The end result of both sub type is same since the same pathways are affected and respond similarly to current standard treatment.

Based on the molecular alterations

Glioblastoma multiforme may be classified according to the molecular alterations into four subtypes:[2]

  • Classic
  • Proneural
  • Mesenchymal
  • Neural
