Surgical resection is recommended for spinal cord ependymomas. Complete tumor removal, prioritizing preoperative neurological status, leads to good outcomes, avoiding radiotherapy for low-grade types.

Area of Science:

  • Neurosurgery
  • Oncology
  • Neuropathology

Background:

  • Spinal cord ependymomas are common in adults.
  • MRI aids diagnosis but cannot always distinguish ependymomas from astrocytomas.
  • Histological evaluation is crucial for definitive diagnosis.

Purpose of the Study:

  • To emphasize the importance of surgical resection for spinal cord ependymomas.
  • To highlight the benefits of gross-total resection and the role of adjuvant therapy.
  • To present long-term outcomes of a surgical strategy.

Main Methods:

  • Surgical resection and histological evaluation for intraspinal cord tumors.
  • Prioritizing complete tumor removal before neurological impairment.
  • Observation and reoperation for tumor recurrence in low-grade ependymomas.

Related Experiment Videos

Main Results:

  • Complete tumor removal was achieved in 86 out of 93 treated spinal cord ependymomas.
  • Only one patient required reoperation for recurrence after 18 years.
  • Gross-total resection without adjuvant radiotherapy yielded good long-term outcomes.

Conclusions:

  • Surgical resection is the gold standard for spinal cord ependymomas.
  • Complete removal should be the primary goal, preserving neurological function.
  • Radiotherapy is generally not recommended for low-grade spinal cord ependymomas.
