title: Expression of NM23 and tenascin in invasive ductal carcinomas of the breast.
abstract: OBJECTIVE
  In this series of ductal carcinoma of the breast, immunoexpression of antimetastasis gene nm23 and tenascin was examined and the role in prognosis was investigated by correlation with the tumour grade and stage, and ER/PR immunoexpression.
  
  
  METHODS
  In this study 27 ductal carcinomas of the breast were analysed for expression of tenascin and nm23 antimetastasis genes by immunohistochemistry.
  
  
  RESULTS
  The results of our study revealed a statistically significant correlation between nm23-H1 immunoexpression and lymph node metastasis. We also found a statistically significant correlation between tenascin and nm23-H1 immunoexpression. Our results suggest that tenascin limits tumour spread.
  
  
  CONCLUSIONS
  Antimetastasis gene expression can be used in predicting lymph node metastasis in ductal carcinomas of the breast.
