ABSTRACT
BACKGROUND:
Extracapsular extension of axillary lymph node (ECE) has significantly increased the risk of locoregional and distant recurrence in breast cancer patients.OBJECTIVE:
Identify markers with high biological aggressiveness since it may serve as a prognostic indicator or adjunct to standard treatment. MATERIAL ANDMETHOD:
The authors immunostained 115 axillary lymph nodes of invasive ductal carcinoma with syndecan-1 and E-cadherin.RESULTS:
The presented data shows a significantly higher number of positive lymph node (8.48 vs. 4.15; p < 0.0001) and larger primary tumor size (3.53 vs. 2.79; p = 0.0029) in ECE patients. Sixty-one cases had node positive and without evidence of ECE, 54 cases had ECE. Syndecan-1 was found to be of significantly high expression (p = 0.001). There was no significant difference in the expression of E-cadherin during progression into extracapsular area (p = 0.12).CONCLUSION:
E-cadherin displays high expression in nodal breast cancer metastases that may have re-expression and has coordinate function with syndecan-1 while invading to the surrounding fatty tissue. The protein is, therefore, likely to play a role in the invasiveness and aggressiveness.
