title: [Survival analysis of 315 cases of laryngectomy].
abstract: OBJECTIVE
  To investigation the clinic long-term result and explore the prognostic factor of patients with laryngectomy.
  
  
  METHODS
  Three hundred and fifteen patients with laryngectomy were analysed. The survival rate and the cause of death were collected from this study.
  
  
  RESULTS
  Five years later, 233 cases were still alive, 60 cases were dead, 22 cases failed to be followed-up. Overall 5-year survival rate was 73.97%, 5-year survival rate for patients of early stage was 82.69. Whereas, for patients of late stage was 62.64%. Five year survival rate for patients of supraglottic carcinoma, glottic carcinoma, subglottic carcinoma and transglottic carcinoma was respectively 73.76%, 82. 55%, 55.56%, 68.75%. Five year survival rate for patients with partial laryngectomy was 79.89%, whereas, for total laryngectomy was 1.03%. The cause of death were local recurrence and cervical glands metastasis.
  
  
  CONCLUSIONS
  Early diagnosis was the key points to both larynx preservation and survival rate. for improving survival rate, we should handle the indications strictly. remain sufficient security cutting edge and follow-up visit.
