title: [Relative factors analysis including carcinoma marker, molecular margin and clinical factors on laryngeal carcinoma recurrence].
abstract: OBJECTIVE
  To investigate the factors of laryngeal carcinoma recurrence, 103 patients of laryngeal carcinoma were analyzed retrospectively on carcinoma marker, molecular margin and clinical factors with univariate analysis and multivariate analysis.
  
  
  METHODS
  CyclinD1, p27, p53 and eIF4E in primary site and surgery margins were detected in laryngeal carcinoma recurrence group and unrecurrence group with immunohistochemical staining to explore the significance of CyclinD1, p27, p53 and eIF4E on laryngeal carcinoma recurrence; The clinical data of 103 patients of laryngeal carcinoma were analyzed retrospectively to investigate the clinical factors of laryngeal carcinoma recurrence; At last above three factors were analyzed with multivariate analysis.
  
  
  RESULTS
  There was significant difference between laryngeal carcinoma recurrence group and unrecurrence group about CyclinD1, p27 and p53 in laryngeal primary site; There was no significant difference between laryngeal carcinoma recurrence group and unrecurrence group about eIF4E. There was significant difference between laryngeal carcinoma recurrence group and unrecurrence group about CyclinD1, p27, p53 and eIF4E in surgery margins. Laryngeal carcinoma recurrence after surgery was related with carcinoma site, T stage, node metastasis, laryngeal carcinoma pathology and operative method; However, it was not related with age, sex and postoperative irradiation therapy with univariate analysis. Laryngeal carcinoma recurrence after surgery was related with T stage, node metastasis, laryngeal carcinoma pathology and operative method with logistic multivariate analysis. At last, laryngeal carcinoma recurrence after surgery was related with T stage, node metastasis, laryngeal carcinoma pathology and positive molecular margins with logistic multivariate analysis.
  
  
  CONCLUSIONS
  The factors of laryngeal carcinoma recurrence is comprehensive. T stage, node metastasis,laryngeal carcinoma pathology and laryngeal carcinoma positive molecular margins were related with laryngeal carcinoma recurrence. Positive molecular margins were more reliable.
