RESUMO
<p><b>OBJECTIVE</b>To study the prognostic factors of 1018 patients with laryngeal cancer treated surgically.</p><p><b>METHODS</b>All patients were treated surgically for laryngeal cancer from 1984 to 1996. A total of 16 clinical factors was studied by univariate analysis and Cox multivariate model.</p><p><b>RESULTS</b>The follow-up rate was 93.5% over 5 years. The overall cumulative survival rate was 79.1% at 3 years, 70.2% at 5 years. The 5-year survival rate of T1N0 is the highest, followed by T1N+, T2N0, T3N0, T4N0, T2N+, T4N+, and T3N+. In univariate analysis, the survival was related to patient age, mobility of vocal cords, preoperative T status, preoperative N status, preoperative UICC stage, postoperative T status, postoperative N status, postoperative UICC stage, topographic location of the tumor and tumor size. In Cox multivariate modal, only postoperative N status, mobility of vocal cords and tumor size were independent prognostic factors.</p><p><b>CONCLUSION</b>Independent prognostic factors for patients with laryngeal cancer after curative resection are postoperative N stage, mobility of vocal cords as well as tumor size. Postoperative follow-up and salvage surgery in time should be attached with importance to improve the survival of patients with laryngeal cancer.</p>
