[Clinicopathologic prognostic factors of laryngeal and pharyngeal tumors. III: Supraglottic carcinoma].

The factors which influenced the prognosis of 306 supraglotic carcinomas were studied. The determinate survival at 3 and 5 years was 7.8% and 57.5% respectively. The lymph node metastases and the presence of recurrence affected significantly the survival. Also showed a worse prognosis those with an advanced local stage, and the patients with excessive alcoholic consumption. Without significative prognostic influence were the grade of tumor differentiation, involvement of surgical margins, previous tracheostomy, and the existence of a second primary tumour.
