title: [Expression of Survivin, Caspase-3 and p53 in surgical margin of laryngeal squamous cell carcinoma and their relationship].
abstract: OBJECTIVE
  To study the expression of Survivin, Caspase-3 and p53 in surgical margin of laryngeal squamous cell carcinoma (LSCC), and their clinical significance and relationship.
  
  
  METHODS
  Immunohistochemistry method was used to detect the expression of Survivin, Caspase-3 and p53 in 116 cases of surgical margin of LSCC.
  
  
  RESULTS
  According to the recurrence, the patients were divided into four group, recurrence within one year, between one year to three years, between three to five years, more than 5 years (include no recurrence). The expression rate of survivin were 92.9%, 85.0%, 50.0% and 21.1% (P < 0.01) in four groups, respectively. The expression rate of Caspase-3 were 50.0%, 50.0%, 66.7% and 89.5% (P < 0.01). The expression rate of p53 were 57.1%, 37.5%, 45.8% and 18.4% (P < 0.05). The expression rate of survivin, caspase-3 and p53 in four groups, respectively, there were significant differences (P < 0.05).
  
  
  CONCLUSIONS
  Expression of Survivin, Caspase-3 and p53 in surgical margin of LSCC may play an important role in the tumorigenesis and development of laryngeal carcinoma. They are feasible for early diagnosis and prognosis estimation.
