[Clinicopathologic prognostic factors in laryngeal pharyngolaryngeal tumors. II. Glottic carcinomas].

Prognostic factors of glottic carcinomas were studied in 211 patients. The 5-year determinate survival was 85.3%. Factors that implied a bad prognosis were an advanced local stage, previous tracheostomy and advanced age. On the other side, alcohol and tobacco abuse, second primary tumors, degree of differentiation, involvement of surgical margins, and postoperatory complications had not any prognostic relevance. There were no differences in T1 and T2 survival either with surgery or radiotherapy, but the last had a greater recurrence rate.
