[Pre-operative radiotherapy for N0 supraglottic carcinoma: a randomized study].

A randomized study on 100 patients of N0 supraglottic squamous cell carcinoma with at least 3 years of follow-up was performed. Surgery alone was used in 56 patients, and combined therapy in 46 patients. The neck failure occurred in 14 (26%) patients and 7 (15%) patients respectively, there was no statistically difference (P = 0.287). Neck failure was higher in T4 stage supraglottic carcinoma for controlling of regional recurrence.
