Abstract Background:

Olfactory neuroblastoma is a rare sinonasal malignancy, with poorly defined treatment protocols. Management at a tertiary centre was retrospectively evaluated to inform future treatment and follow up.


Cases treated with curative intent (2000–2014) were included. Data were collected, and overall and disease-free survival rates were calculated.


Eleven cases were identified, with a median follow up of 87 months. One patient was Kadish stage A, one was stage B, eight were stage C and one was stage D. The latter patient underwent chemoradiotherapy alone. The remaining patients proceeded to: endoscopic-assisted wide local excision (n = 2), anterior craniofacial resection (n = 4) or endoscopic craniofacial resection (n = 4). No patients had primary nodal disease or elective neck treatment. One patient had neoadjuvant chemoradiation. Six patients had post-operative radiotherapy; three received adjuvant chemotherapy. Two patients had late cervical node failure, and proceeded to neck dissection and post-operative radiotherapy. Two patients had late local recurrence. Ten-year overall and disease-free survival rates were 68.2 and 46.7 per cent, respectively.


Longer-term follow up is supported given the incidence of late regional and local recurrence. Prophylactic treatment of cervical nodes in locally advanced disease is an area for further investigation.
