Introduction: Ependymomas are central nervous system tumors that significantly impact the quality of life of patients and carry a high mortality rate. Both the disease itself and its treatment cause significant morbidity. At a national level, there are no reports on the frequency and characteristics of the disease, and regional reports are also scarce. Objective: To identify the clinical demographic characteristics, prognostic factors, and survival of pediatric and adolescent patients diagnosed with ependymoma at the National Institute of Neoplastic Diseases (INEN). Materials and methods: Retrospective cohort study of a series of cases, with a cross-sectional and analytical design. From 2012 to 2022, 85 patients aged 0-19 years with a diagnosis of ependymoma were included. Results: The mean follow up time was 56.68 months. The overall survival and progression free survival of the entire cohort at 5 years were 55,89% (95% CI: 44,28 - 65,99) y 37,71% (95% CI: 26,21-49,16) respectively. The main prognostic factors identified were age under 3 years (p=0.01), complete treatment (p=0.019), adjuvant chemotherapy (p=0.048), presence of metastasis (p=0.012), and disease recurrence (p=0.02). Conclusions: The survival of patients with ependymoma is below that reported in high income countries. Incomplete treatment and treatment abandonment are factors that negatively impact the prognosis. Further studies are needed to identify barriers in the referral and treatment process for patients with ependymoma.
