Transnasal endoscopic surgery in selected nasal‐ethmoidal cancer with suspected brain invasion: Indications, technique, and outcomes

Abstract

Background

In nasal‐ethmoidal malignancies, brain involvement is associated with dismal prognosis.

Method

Patients undergoing endoscopic resection with transnasal craniectomy and subpial dissection (ERTC‐SD) for brain‐invading nasal‐ethmoidal cancer between 2008 and 2016 were included. Complications were analyzed in all patients, whereas oncological outcomes only in patients with pathological brain invasion. The prognostic impact of previous treatments, brain edema, and histology was assessed. Hospitalization ratio was calculated.

Results

Nineteen patients received ERTC‐SD and 11 had pathological‐proven brain invasion. Histologies were 6 olfactory neuroblastomas (ONB), 3 neuroendocrine carcinomas, and 2 intestinal‐type adenocarcinomas. Mean follow‐up was 21.9 months. Three‐year overall, local recurrence‐free, and distance recurrence‐free survivals were 65.5%, 81.8%, and 68.2%, respectively. Overall and distant recurrence‐free survivals were significantly better in patients with ONB (P = 0.032 and P = 0.013, respectively). Hospitalization ratio was 4.1%. Complication rate was 10.5%.

Conclusion

In selected nasal‐ethmoidal tumors with brain invasion, ERTC‐SD can provide good local control, satisfactory survival, and limited morbidity.
