Abstract

The nm23 gene was originally identified by differential hybridization of metastatic murine melanoma cell lines. Some experimental studies demonstrated a significantly low metastatic potential of melanoma cell lines transfected with the nm23 gene. In this study, we clarified the relationship between intracellular nm23-immunoreactivity and lymph nodal status of human breast cancer. We analyzed 82 surgically removed breast tumors including 67 invasive carcinomas (ductal, lobular and mucinous carcinomas). The nm23 expression was diffusely positive in the benign tumors and non-invasive carcinomas. Of the invasive ductal carcinomas, lymph node metastasis was found in 67.7% (21/31) of the focally positive/negative cases and in 18.2% (4/22) of the diffusely positive cases (p<0.001). Immunohistochemically, advanced margins of invasive carcinomas with lymph node metastasis were shown to be negative for nm23 expression, while intraductal carcinoma components were positive. This observation suggested that focally positive/negative nm23 expression can be a predictor of lymph node metastasis of invasive ductal breast carcinoma.
