Outcome predictors in the management of spinal cord ependymoma.
The aim of this study was to determine predictors of functional outcome and survival in a retrospective cohort of spinal cord ependymomas treated at a single institution. Twenty-six patients who underwent treatment of spinal cord ependymoma at a single institution were retrospectively analysed. The clinicopathological features were reviewed and correlated with functional outcome (measured using the Frankel grade), recurrence (clinical or radiological), progression-free survival (PFS) and overall survival (OS). Seventy-nine percent of patients with complete excision had maintained or improved functional outcome, compared to 75% in the incomplete resection plus radiotherapy group. Patients with a good pre-operative Frankel grade tended to maintain their functional status, though this did not reach statistical significance (Fisher's Exact test, P = 0.090). Univariate analysis revealed that longer symptom duration prior to treatment was associated with poorer functional outcome (P = 0.006). Extent of resection and the use of adjuvant radiotherapy did not influence PFS or OS; however, early diagnosis and treatment are paramount in the management of spinal ependymoma if a good functional outcome is to be achieved.
