This study aims to analyze whether the expressions of E-cadherin and NM23HI can be used as predictors of ductal
carcinoma metastasis in various degrees of histological malignancies.
Paraffin blocks were obtained from 97 patients with invasive breast ductal carcinoma with malignancy grade 1, 2 and 3
who came to several hospitals in Jakarta and Bandung from 2000 to 2006. Histopathological examinations of eosin hematoxylin
slides of primary and secondary tumors were done to diagnose the degree of histological malignancy and metastasis status.
Further, immunohistochemistry staining of E-cadherin, NM23HI and cytokeratin were done followed by scoring according the
number of positive cells and staining intensity. The associations of E-cadhetin and NM23H1 expression with the presence of
metastasis and grade of histological malignancy were analyzed.
Subjects were 29-75 years old (mean: 48.19 years), with most subjects aged 40-45 years old, with malignancy grade 1, 2
and 3 of 18.56%; 45.36% and 36.1% respectively. There was a significant association between E-cadherin and NM23HI expression
in primary tumor with the possibility of invasion and metastasis inhibition by 14 times and 11 times respectively compared
to those with negative E-cadherin and NM23HI expression. The ROC curve showed that E-cadherin (r=0.755) and NM23HI
(r=0.827) expressions were strongly associated, sensitive and specific as metastasis markers.
E-cadherin and NM23HI expressions can be used as invasion and metastasis markers, but cannot be used as markers
for the degree of histological malignancy of invasive ductal carcinoma.

NM23H1 at ductal invasive carcinoma breast cancer and metastasis at lymph node and E-cadherin and NM23H1 as metastasis predictors for
various degrees of histological malignancy in invasive ductal carcinoma.
