title: [Clinicopathologic prognostic factors in laryngeal and pharyngolaryngeal tumors. I. Carcinoma of the pyriform sinus].
abstract: Prognostic factors of pyriform sinus carcinomas were studied in 122 patients. The 5-year determinate survival was 25.8%. Factors that implied a bad prognosis were an advanced local and nodal stage, and the degree of differentiation. At variance, alcohol and tobacco abuse, age, previous tracheostomy, involvement of surgical margins and local complications had not any prognostic significance.
