H&E, anti-EMA, CK 19 and FVIII factor staining was used to identify tumor cells in both lymph nodes and tumor tissues and to count the microvessels. A total of 882 lymph nodes were examined.RESULTS Immunostaining-positive tumor cells were found in 9.0 % (79/882) of the dissected lymph nodes. The positive rates were not significantly different between a surviving group and a deceased group (P>0.05). The microvessel count was significantly higher in group that had died (P<0.001).CONCLUSION The lymph node micrometastases did not show any correlation with patients survival, but the microvessel density had a negative correlation with the survival period in breast cancer patients who had negative axillary lymph nodes.
