Abstract

Objectives

Intestinal-type adenocarcinoma (ITAC) of the ethmoid mostly affects patients exposed to wood dust and has been traditionally treated with bilateral resection. The aim of the present study was to validate unilateral endoscopic resection with transnasal craniectomy (uERTC) in selected ITACs.

Materials and methods

Patients affected by ITAC receiving uERTC from 2004 to 2017 at two tertiary referral centers were retrospectively analyzed. A control group of patients treated with bilateral endoscopic resection with transnasal craniectomy (bERTC) was selected. Olfaction, taste, and quality of life were evaluated. Survival and functional outcomes in the two groups were compared.

Results

Fifty-four patients who underwent uERTC (case group: 27/54) or bERTC (control group: 27/54) were enrolled. The two groups were statistically comparable. Five-year overall (OS), disease-specific (DSS), recurrence-free (RFS) survivals, and local recurrence rates were not significantly different between groups. Hospitalization time was significantly shorter in the uERTC group (p = 0.0004) and no significant difference in terms of complications was demonstrated. The rate of subjective olfaction preservation was significantly higher in the uERTC group (45.5%) than in the bERTC group (0.0%) (p = 0.0007). Median 22-Items Sinonasal Outcome Test (SNOT-22) values were not significantly different between groups. No significant association of olfaction and taste preservation/worsening with reconstructive technique, radiation therapy, and chemotherapy was observed.

Conclusions

uERTC is an adequate surgical procedure for selected unilateral ITAC with similar survival rates and lower morbidity compared to bERTC. A rigorous follow-up of patients with ITAC is crucial and strongly recommended independently of the extent of resection.
