Patterns of Failure and Outcome in Esthesioneuroblastoma

Abstract

The development of cervical nodal metastases and distant metastases had a significant adverse impact on prognosis. The value of the Kadish staging system was confirmed in our study, significantly correlating with prognosis. Tumor grade according to the Hyams staging system also seems to be an important factor in determining prognosis for tumor recurrence and survival. Aggressive multimodality therapeutic strategies, particularly CFR and adjuvant RT, yielded the best treatment outcome.
