title: [Clinicopathological significance of CD137L expression in laryngeal carcinoma].
abstract: OBJECTIVE
  To study the expression of CD137L in laryngeal carcinoma, and to analyze its clinicopathological significance.
  
  
  METHODS
  The expression of CD137L in 50 laryngeal carcinoma specimens and 9 normal laryngeal mucous tissues were detected by immunohistochemical staining.
  
  
  RESULTS
  The positive CD137L staining were found in all 50 cases of laryngeal carcinomas (100%), while its staining were negative in normal laryngeal mucous. There was significant difference between two groups (P < 0.01). The positive ratio of CD137L staining had no relationship with the factors such as age, sex and tumor site, while it had significant correlation with the pathological stage, T stage and lymph node metastasis.
  
  
  CONCLUSIONS
  The expression of CD137L might play an important role in the development of laryngeal carcinomas.
