title: [The expression of cathepsin-D in salivary adenoid cystic carcinoma].
abstract: OBJECTIVE
  To investigate the relationship between Cathepsin-D(Cath-D) and the prognosis of patients with salivary adenoid cystic carcinoma (SACC).
  
  
  METHODS
  The immunoactivity of Cath-D of 52 cases with SACC was determined by immunohistochemistry method (Streptavidin-Biotin method). The relationship between Cath-D and the histological type, clinical stage, local recurrence, distant metastasis of the tumor and survival rate of the patients with SACC were analysed.
  
  
  RESULTS
  Statistical analysis showed that the expression levels of Cath-D were correlated positively with distant metastasis potential and clinical stage (P < 0.05), and had no significant relation with histological type, local recurrence and survival rate (P > 0.05).
  
  
  CONCLUSIONS
  Cath-D can facilitate invasiveness and distant metastasis of SACC; evaluation of Cath-D can act as a predictor of distant metastasis of SACC and direct the clinical treatment.
