Abstract

Background:

The optimal management of glottic carcinoma involving the anterior commissure is controversial.

Method:

A retrospective analysis was conducted of 76 patients with glottic squamous cell carcinoma treated by transoral carbon dioxide laser resection by a single surgeon.

Results:

Sixty-three patients (with tumour stage Tis–T3) were eligible for inclusion. Thirty patients had involvement of the anterior commissure; these patients were significantly more likely to have either uncertain or positive margins (63.3 vs 30.3 per cent, p = 0.012), and were also more likely to receive adjuvant radiotherapy (40 vs 3.2 per cent, p = 0.0005). The overall laryngeal preservation rate was 96.8 per cent; there was no statistically significant difference between those with and without anterior commissure involvement (96.7 and 96.9 per cent respectively).

Conclusion:

Transoral laser resection with the use of adjuvant radiotherapy in a minority of patients with adverse pathological findings can be recommended for the primary treatment of anterior commissure glottic cancer from an oncological perspective; excellent local control and laryngeal preservation rates can be achieved.
