Objective: In this series of ductal carcinoma of the breast, immunoexpression of antimetastasis gene nm23 and tenascin was exa­mined and the role in prognosis was investigated by correlation with the tumour grade and stage, and ER/PR immunoexpression. Material and Methods: In this study 27 ductal carcinomas of the breast were analysed for expression of tenascin and nm23 anti­metastasis genes by immunohistochemistry. Results: The results of our study revealed a statistically significant correlation between nm23-H1 immunoexpression and lymph node metastasis. We also found a statistically significant correlation between tenascin and nm23-H1 immunoexpression. Our results suggest that tenascin limits tumour spread. Conclusion(s): Antimetastasis gene expression can be used in predicting lymph node metastasis in ductal carcinomas of the breast.
