They comprise 2–6% of CNS tumors, and up to 60% of intramedullary tumors. In this study, we retrospectively analyzed prognostic factors affecting progression-free survival (PFS) and postoperative outcomes for 38 patients. Methods: Clinical and histological data were collected for 38 patients treated at a single neurosurgical center (2012–2021). Data included presenting symptoms, tumor grade and location, type of management (gross total resection [GTR], subtotal resection [STR], or conservative), use of adjuvant therapy, and outcomes such as PFS and functional status. Results: Patients averaged 55 years of age, and there was an equal gender distribution. Tumors most commonly occurred in the lumbar spine (58%), and 47% were classified as the World Health Organization Grade II. Pain was the most frequent presenting symptom (79%). GTR was achieved in 58% of patients, STR in 36%, and 13% were managed conservatively. GTR significantly reduced tumor progression compared to STR (P = 0.008); no progression was observed in the GTR group. Functional outcomes were better with GTR; 58% of patients showed improvement postoperatively versus 50% in the STR group. Adjuvant therapy was utilized in 18% of cases and showed no significant impact on PFS or functional outcomes (P > 0.99). The overall 5-year PFS rate was 75%. Conclusion: This study underscores the importance of GTR in reducing progression while preserving functional outcomes in spinal ependymoma. Adjuvant therapy remains controversial, with limited evidence supporting its benefit.","thumbnailUrl":"https://sni-digital-videos.s3.amazonaws.com/articles/e9436919-4d1b-4cf4-9f14-e8a28bc4d11e/featured/hero-1781557439461.png","publishDate":"2026-06-05T00:00:00.000Z","doi":"10.25259/SNI_1003_2025","categories":["Spine","Original Article"],"fullTextUrl":"https://surgicalneurologyint.com/wp-content/uploads/2026/06/14596/SNI-17-344.pdf"}
