Management of Cancer of the Supraglottis

Abstract

We present the results of a retrospective study of 903 patients treated with conservation surgery for carcinoma of the supraglottic larynx so we can evaluate our management of supraglottic cancer with different types of surgery. In 301 patients, an extended supraglottic laryngectomy was performed. The recent selective use of transoral laser resection appears to be a rational approach. The 5-year uncorrected survival was 84%, 81%, 76%, and 55% for stages I, II, III, and IV, respectively. The most common site for local-regional failure was the cervical lymphatics. The percentage of occult disease in the N0 neck was 21% and epilaryngeal supraglottic location, locally advanced and GIII tumors have a higher frequency of lymph node involvement. There were no differences between comprehensive and anterolateral elective neck dissections. A bilateral elective neck dissection is recommended. In histologically positive neck disease, the survival rates were better with postoperative radiotherapy only in cases of extracapsular spread.
