title: [Relevant factors of nm23 protein expression and dangerous factors of bone metastasis in breast cancer].
abstract: OBJECTIVE
  To investigate the relevant factors of the expression of nm23 protein and the dangerous factors of bone metastasis in breast cancer.
  
  
  METHODS
  Seventy-six breast cancer patients confirmed by histological examination after surgeries were enrolled in this study. nm23 protein expressions in original breast cancer tissues were detected by immunohistochemical procedures. The relevant factors of nm23 protein expression and the dangerous factors of bone metastasis were conducted logistic regression analysis.
  
  
  RESULTS
  Among the 58 breast cancer patients who did not have bone metastasis in the observation period, 55 did not have bone metastasis;while the other 18 breast cancer patients having bone metastasis were confirmed in only 14 patients. The correction was 94.83% and 77.78% respectively. The general correction was 90.79%.
  
  
  CONCLUSIONS
  The detection of nm23 protein is helpful to evaluate prognosis and improve the therapy. It is one of the important methods to instruct the breast cancer patients to perform radio-nuclide imaging in the follow-up.
