Analysis of prognostic variables and results after supraglottic partial laryngectomy.

A consecutive series of 78 patients who underwent conservation surgery for squamous cell carcinoma of the supraglottic larynx is analyzed. The majority of the patients were middle-aged men who had early-stage disease, with only 18 patients in stage III and 6 in stage IV. The epiglottis was the most frequent site, followed by the aryepiglottic fold and other sites in the supraglottic larynx. There was no operative mortality and the complication rate was low. Univariate analysis showed no influence of tumor stage, tumor differentiation, or involved surgical margins on survival. Determinate survival rates of 85 percent at 3 years and 72 percent at 5 years were observed. Local recurrences took place in 12 patients, 4 of whom were salvaged by total laryngectomy; neck failure occurred in 13 patients, 7 of whom were salvaged after further treatment; and 1 of the 2 patients with distant metastasis was salvaged after further treatment. We believe that every patient with a favorable lesion of the supraglottic larynx should be considered for conservation surgery, specifically, supraglottic partial laryngectomy, adhering to the criteria mentioned. Initial surgical treatment offers excellent local control and 5 year survival. Adjuvant postoperative radiotherapy may be considered in those patients with bulky primary tumors, positive surgical margins, and histologically confirmed cervical lymph node metastases.
