Ependymomas, rare neuroectodermal tumors, are best treated with surgery. Radiotherapy is recommended for high-grade or incompletely resected tumors, while chemotherapy shows no proven benefit for ependymoma treatment.

Area of Science:

  • Neuro-oncology
  • Neurosurgery
  • Radiation Oncology

Background:

  • Ependymomas are rare neuroectodermal tumors with varying grades (I-III).
  • Infratentorial location is most common (60%).
  • Prognosis is influenced by age (<40) and surgical extent, but tumor grade and site roles are unclear.

Purpose of the Study:

  • To review current treatment standards for ependymomas.
  • To clarify the role of surgery, radiotherapy, and chemotherapy.
  • To outline prognostic factors and treatment recommendations based on tumor grade and resection extent.

Main Methods:

  • Literature review of ependymoma treatment guidelines and prognostic factors.
  • Analysis of treatment outcomes based on tumor characteristics and interventions.

  • Synthesis of evidence regarding the efficacy of surgery, radiotherapy, and chemotherapy.

    • Main Results:

    • Surgery is the primary treatment for ependymomas.
    • Postoperative radiotherapy is indicated for high-grade tumors and recommended for low-grade tumors with incomplete resection.
    • Radiotherapy doses range from 45-60 Gy based on grade.
    • Chemotherapy has not demonstrated improved outcomes, even at recurrence.

    Conclusions:

    • Surgery remains the cornerstone of ependymoma management.
    • Adjuvant radiotherapy is crucial for specific patient groups.
    • Current evidence does not support the routine use of chemotherapy for ependymomas.
