Background: Due to the peculiar location of central neurocytoma, gross total resection is often challenging, and adjuvant radiotherapy is sometimes indicated. Factors associated with outcome are not well addressed in the literature Methods: A multicenter retrospective cohort study among 11 centers in Saudi Arabia including histologically confirmed central neurocytoma between 2000-2022. Results: A total of 104 patients were included. Pre-operative mRS was 0-2 in 93% of the cases. Gross total resection (GTR) was achieved in 50.7%. Radiotherapy was needed in 40% and Ventriculoperitoneal shunt in 38.6%. Favorable outcome was observed in 81.7%. Factors associated with worse outcome included initial mRs of ≥3, tumor size ≥50 mm, and atypical/anaplastic histology. Disease progression was observed in 18 (17.8%). Five-year absolute survival rate was 91.55%. The only significant predictor of disease progression was the presence of atypical features or anaplasia (P .007). Extent of surgical resection (P 0.877) wasn’t associated with disease progression. Post operative radiotherapy didn’t alter residual progression in patients with subtotal resection (P .170) nor the recurrence rate in those with GTR (.365) Conclusions: Central Neurocytoma cases have a high survival rate with a favourable mRs score at long-term follow up. The extent of resection didn’t alter disease progression nor did the adjuvant radiotherapy
