Supracricoid laryngectomy with cricohyoidopexy: oncological results

This study assessed the oncological results in patients undergoing supracricoid laryngectomy with cricohyoidopexy. A cohort of 44 patients surgically treated using supracricoid laryngectomy with cricohyoidopexy between June 2001 and December 2009 was retrospectively analyzed. The mean follow-up period was 53.2 (±24.7) months. The Kaplan-Meier method was used to analyze overall survival and disease-specific survival, as well as survival according to T2 and T3 subgroups. Overall survival rates at 3 and 5 years were 90.5 and 84.1%, respectively. The 3- and 5-year disease-specific survival rates were 95.4 and 92.5%, respectively. Overall survival for patients with T2 disease was 87.5% at 3 years and 80.8% at 5 years. For T3, the corresponding rates were 91.8 and 87.0%. Disease-specific survival for patients with T2 disease was 93.3% at 3 years and the same at 5 years; the corresponding rates for T3 were 96.4 and 91.4%. The differences between T2 and T3 patients at 3 and 5 years with respect to overall and disease-specific survival were not statistically significant (P = 0.903 and P = 0.863, respectively). Recurrence was local in one patient (2.2%) and regional in three (6.8%). There were three distant metastases (6.8%) and one second primary carcinoma (2.2%). These findings support the use of supracricoid laryngectomy with cricohyoidopexy as an oncologically safe technique in properly selected patients with laryngeal carcinoma.
