Esthesioneuroblastoma: Reflections of a 21‐Year Experience

Abstract

This series of esthesioneuroblastoma patients (N=35) reflects an 8-year disease-free survival of 80.4%, representing a significant number of patients treated and followed at one institution for an extended period of time. No valuable pathological or molecular indicators to predict aggressive clinical behavior were found. The average time interval before recurrent disease developed was more than 6 years, far greater than that expected for other sinonasal malignancies. Therefore, extended follow-up is necessary for this patient group.
