Esthesioneuroblastoma: the massachusetts eye and ear infirmary and massachusetts general hospital experience with craniofacial resection, proton beam radiation, and chemotherapy.

Abstract

OBJECTIVES:

To determine the efficacy of craniofacial resection and proton radiation for the management of esthesioneuroblastoma (ENB).

DESIGN:

A retrospective chart review was performed of all patients presenting with ENB and completely managed at the Massachusetts General Hospital (MGH) and the Massachusetts Eye and Ear Infirmary (MEEI) from 1997 to 2006.

SETTING:

A tertiary referral center.

MAIN OUTCOME MEASURES:

Disease-free and overall survival.

PARTICIPANTS:

All patients presenting with ENB and completely managed at the MGH and the MEEI from 1997 to 2006.

RESULTS:

Ten patients were identified with a median follow-up time of 52.8 months. Average age at presentation was 45 years. Nasal obstruction was the most common presenting symptom. Three patients presented with Kadish stage B disease and seven with stage C. No patient had evidence of cervical or metastatic disease at presentation. Seven patients were treated with craniofacial resections (CFR) followed by proton beam radiation with or without chemotherapy. Three patients were treated with initial chemotherapy with no response. They subsequently underwent CFR followed by proton beam radiation. The 5-year disease-free and overall survival rates were 90% and 85.7%, respectively, by Kaplan-Meier analysis. No patient suffered any severe radiation toxicity.

CONCLUSION:

ENB can be safely and effectively treated with CFR followed by proton beam irradiation. Proton irradiation may be associated with less toxicity than photon irradiation. The role of chemotherapy remains unclear.
