title: [Expression of p27 protein and cyclinD1 in laryngeal carcinoma].
abstract: OBJECTIVE
  To find out whether the expression of p27 and cyclin D1 is different in laryngeal squamous cell carcinoma and the edge tissues, and to study the relationship between the expression of p27 and cyclin D1 with the clinic character in patients with laryngeal squamous cell carcinoma.
  
  
  METHODS
  An immunohistochemistry method was used to study the expression of p27 protein and cyclinD1 in 38 laryngeal squamous cell carcinoma and the edge tissues.
  
  
  RESULTS
  The expression of p27 protein and cyclin D1 was significantly different between the laryngeal carcinoma and the edge tissue. Low expression of p27 and over expression of cyclinD1 was associated with the liability of lymph node metastasis and the poor prognosis for patient with laryngeal squamous cell carcinoma. An interesting observation was that the inverse expression between p27 and cyclinD1 might play an important role in laryngeal squamous cell carcinoma.
  
  
  CONCLUSIONS
  p27 protein and cyclinD1 in laryngeal carcinoma is apparently a significance predictor of survival.
