PURPOSE/ OBJECTIVES: To analyze the clinical features, treatment modalities and outcome of patients treated for a localized esthesioneuroblastoma (ENB). MATERIALS AND METHODS: Forty-three consecutive patients with biopsy proven ENB treated at two referral cancer centers between 1998 and 2010 were retrospectively reviewed. RESULTS: Overall, 5 patients had stage A disease, 13 stage B, 16 stage C and 9 stage D according to the modified Kadish classification. Neo-adjuvant chemotherapy was performed in 23 patients leading to a 74 % response rate. Thirty-one patients were treated by surgery. Thirty-nine patients (90.6%) underwent radiation therapy. Twelve patients received bilateral cervical lymph node irradiation (LNI). After a median follow-up of 77 months, the 5-year overall and progression free survival were 65% and 57%. Twelve patients (28%) had a locoregional relapse leading to 10 ENB-related deaths. The major prognostic factor was the modified Kadish stage with a 3-year survival for stage A-B, C and D of 100%, 48% and 22% respectively (p < 0.0001). Two (9%) isolated cervical lymph node relapses occurred among staged B and C patients treated without elective LNI and none after elective or adjuvant LNI. CONCLUSION: The high risk of locoregional failure in ENB justifies the use of multimodal therapy. Induction chemotherapy leads to a high response rate. Elective LNI might prevent regional failure in locally advanced disease.
