[Survival analysis of 1115 patients with laryngeal carcinoma]

To study the long-term result of patients with laryngeal carcinoma treated by surgery and the prognostic factors.

The survival status of 1115 patients with laryngeal carcinoma which were treated in this department between 1983 and 1996 were retrospectively investigated.

Overall 5-year survival rate was 77%. Among them, 5-year survival rate for patients of stage I was 94%, stage II 89%, stage III 82%, stage IV 66%. Patients with glottic cancer had the best prognosis, followed by supraglottic, subglottic and transglottic cancer. Five years survival rate for patients with partial laryngectomy was 85%, whereas, for total laryngectomy was 68%. The causes of failure were local recurrence and metastasis(70%). 14% of dead was not clear.

Early diagnosis was the key for both larynx preservation and survival rates. Causes of dead were laryngeal recurrence and metastasis.
