title: [Retrospective analyses of postoperative survival of laryngeal carcinoma patients at late stage].
abstract: OBJECTIVE
  To compare the postoperative survival rate of laryngeal carcinoma patient at stage III or IV whom accepted partial laryngectomy and total laryngectomy.
  
  
  METHODS
  We performed a retrospective cohort follow-up study of 126 patients of stage III or IV who underwent operation for laryngeal carcinoma in Chinese PLA General Hospital between January, 2005 and December, 2009. Survival rates were calculated by product-limit method.
  
  
  RESULTS
  There were 80 patients at stage III and 46 patient at stage IV. Sixty five patients underwent partial laryngectomy and 61 patients underwent total laryngectomy. There were 24 patients in whole group died in the 5 years, 15 of them underwent partial and 9 accepted total laryngectomy. The 5-years survival rate of partial and total group were 62.58% and 68.74% respectively. The survival curve of both groups had no significant difference (P < 0.05).
  
  
  CONCLUSIONS
  For laryngeal carcinoma patients at later stage, with suitable operative indication, the partial laryngectomy could achieve an acceptable effect as well as total laryngectomy.
