title: [Nuclear factor kappaB/p65 and cyclooxygenase-2 expression and clinic significance in human laryngeal squamous cell carcinoma].
abstract: OBJECTIVE
  To investigate nuclear factor-kappaB/p65(NF-kappaB/p65) and cyclooxygenase-2 (COX-2) gene expressions and clinical significance in human laryngeal squamous cell carcinoma, at the same time to investigate the relationship between the two gene expressions.
  
  
  METHODS
  Forty-one samples of laryngeal squamous cell carcinoma and ten samples of vocal cord polyps were assayed using immunohistochemical SP method for detection of NF-kappaB/p65 and COX-2 protein expression level.
  
  
  RESULTS
  There is significant difference between the laryngeal carcinoma group and vocal cord polyps group about NF-kappaB/p65 and COX-2 protein expression level. Qualitative analysis found theres significant relationship between COX-2 and histological classification. There's significant correlation relationship between NF-kappaB/p65 and COX-2 by using spearman correlation analysis.
  
  
  CONCLUSIONS
  (1)The expressions of NF-kappaB/p65 and COX-2 both raise in laryngeal carcinoma. (2) NF-kappaB/p65 perhaps promotes the expression of COX-2 in laryngeal carcinoma. (3) NF-kappaB was hoped to become the new treated target of laryngeal carcinoma.
