Analysis of the Relationship between Expressions of TF and MMP-9 and Prognosis of Breast Cancer Patients

OBJECTIVE To investigate expression of the tissue factor (TF)and matrix metalloproteinase-9(MMP-9)in breast cancers, and to assess their expression in relation to possible prognostic significance. METHODS The expression of TF and MMP-9 in 71 breast cancer specimens were determined by EnVision immunohistochemistry, and the positive expressions related to the patient clinical outcome. RESULTS Positive rates of TF and MMP-9 staining were respectively 43.7%and 42.3%.K-M monofactorial analysis showed that the 5-year survival rate of the patients with a positive expression of TF and MMP-9 was lower than those with negative expression(P<0.05).However,the COX multifactorial analysis indicated that TNM staging and lymph node metastasis were the prognostic factors for breast cancer patients,and that TF and MMP-9 could not be used as the independent prognostic factors(P >0.05). CONCLUSION The positive rates of TF and MMP-9 were considerably high in breast cancers,which could provide useful information for patient prognosis.
