Purpose:
The aim of the present paper was to investigate the oncological safety of two-stage bilateral cordectomy for the treatment of cT1b glottic SCC, and to compare its oncological outcome and synechia development rate with those of single-stage procedures.
Materials And Methods:
A retrospective cohort study was performed at the Otolaryngology Unit of Vittorio Veneto Laryngeal Cancer Center (Italy). The prognostic significance of clinical, pathological and surgical factors was also investigated, in terms of recurrence rate and disease-free survival, in a univariate statistical setting.
Results:
Our results indicate that patients treated with primary two-stage bilateral cordectomy achieved local control in 96% of cases, with 95% disease-specific and 88% overall survival rates, and a 95% organ preservation rate, with anterior synechiae developing in 1 case. Involvement of the deep surgical margins correlated with a worse prognosis. Patients developed anterior synechiae less frequently after two-stage bilateral cordectomy, and experienced no higher recurrence rate or shorter disease-free survival than patients treated with a single-stage procedure.
Conclusions:
Two-stage bilateral cordectomy is a safe and effective procedure. In selected patients it could be considered the primary approach for the treatment of early glottic cT1b carcinomas.
