title: [Treatment and clinical analysis of laryngeal function preserving surgery in hypopharyngeal carcinoma].
abstract: OBJECTIVE
  To evaluate the therapeutic effect and the prognosis of the laryngeal function preserving surgery (LFPS) and total laryngectomy in hypopharyngeal carcinoma.
  
  
  METHODS
  Ninety-three cases of laryngopharynx carcinoma were retrospectively analyzed from September 1974 to September 2006. Among which 57 cases were primary pyriform sinus cancer, 20 cases were postero-cricoid cancer and 16 cases were postero-pharyngeal wall cancer. 53 cases were treated by LFPS, and 40 cases were treated by total laryngectomy. The treatment effectiveness, complication, survival rate and repair materials were analysed.
  
  
  RESULTS
  Adopting Kaplan-Meier survival analysis, the 3-year survival rates were 69.9% and 5-year survival rates were 43.0%. The 3-year survival rates of LFPS and Non-LFPS were 73.6% and 67.5%, and the 5-year survival rates of LFPS and Non-LFPS were 49.1% and 32. 5%. There was no significant difference between the two groups (chi2 = 2.566, P > 0.05). Single element analysis indicated survival rates concerned with T-stage (chi2 = 9.764, P < 0.05), neck lymphatic transfer (chi2 = 10.472, P < 0.01) and the degree of pathological differentiation (chi2 = 25.894, P < 0.01). Cox regression analysis suggested that T-stage, the degree of pathological differentiation and whether going through the surgical operation were the independent element of the patient's prognosis. There was no significant difference between LFPS and No-LFPS in the neoplasms location, complication, neoplasms residuum and neoplasms recurrence.
  
  
  CONCLUSIONS
  LFPS did not affect the survival rates and LFPS was feasible. LFPS can increase the living quality of laryngopharynx carcinoma patients.
