Main Results:

  • Pediatric ependymomas show different genomic profiles than adult tumors.
  • Ependymomas from different central nervous system (CNS) locations have distinct genomic profiles.
  • Evidence supports the role of cancer stem cells in tumor resistance and recurrence.

Conclusions:

  • Genomic analysis reveals key differences in pediatric ependymomas.
  • Cancer stem cell hypothesis offers insights into treatment resistance.
  • Targeting molecular alterations in tumor-initiating cells represents a new treatment paradigm.
