Multicenter assessment of exclusive endoscopic endonasal approach for the treatment of 53 olfactory neuroblastomas

Abstract

Background

Given the particularities of olfactory neuroblastoma (ONB) and the lack of studies on the subject, a multicenter collaborative study was conducted to assess treatment strategy.

Methods

Fifty-three patients with ONB were included from the French Rare Head and Neck Cancer Expert Network (REFCOR) database: 16T1, 8T2, 19T3, and 10T4. All cases were treated endoscopically with skull base removal and repair in 26 cases (49%) and without external craniotomy.

Results

The overall survival (OS) and disease-free survival (DFS) rates at 5 years were 87% and 71%, respectively, with mean follow-up of 45.4 ± 26.5 months. The complication rate was 18.8% with 4 cases of meningitis. Pathological analysis showed positive margins in 26.8%, notably on the dura-mater and periorbita, without impairment of OS or DFS. Forty-eight patients received adjuvant radiotherapy on T ± N. Ten patients had a recurrence (18.9%). Six patients died of their disease. Prophylactic neck irradiation seemed to reduce the recurrence rate.

Conclusion

Exclusively endoscopic treatment proved efficient and reliable in a large controlled series.
