title: Expression profile of p63 in 127 patients with laryngeal squamous cell carcinoma.
abstract: OBJECTIVE
  To evaluate p63 expression in laryngeal squamous cell carcinoma and its prognostic significance.
  
  
  METHODS
  p63 expression was examined by immunohistochemistry and scored in 127 patients with laryngeal squamous cell carcinomas.
  
  
  RESULTS
  Sixty-two cases had scored 3, sixty had scored 2, four had scored 1 and one case did not show any expression (48.8, 47.2, 3.1 and 0.8%, respectively). Overall survival was 73.9% at 24 months and 59.5% at 60 months. The disease-free survival was 77.2 and 75.1%, and the disease-specific survival was 79 and 67% at 24 and 60 months, respectively. Uni- and multivariate analysis identified that decreased immunoexpression of protein p63 was a statistically significant factor for the risk of recurrence and death by cancer.
  
  
  CONCLUSIONS
  p63 expression was highly prevalent in laryngeal squamous cell carcinomas, and its underexpression was correlated with a worse prognosis.
