Expression and Clinical Significance of nm23 Genes in Primary Breast Carcinomas / 中国医师杂志

ABSTRACT

Objective To study expression and clinical significance of nm23 genes in primary breast carcinomas. Methods The expression of nm23 was detected by immunohistochemical S-P method in 286 cases of primary breast carcinomas. Results The positive rate of nm23 expression was 65.7%. There was not a significant correlation between the positive rate of nm23 and patients' age, tumor pathological types. There was a significant relation between the expression of nm23 and tumor clinical stage, axillary lymph node metastasis, and the positive rate of nm23 expression in the cases of clinical stage I without axilliary lymph node metastasis was significantly higher than that in the cases of clinical stage III with axilliary lymph node metastasis. Conclusion The expression of nm23 gene was negatively related with clinical stage and axilliary lymph node metastasis in breast carcinomas, which indicated that nm23 gene expression may serve as an index for predicting lymph node metastasis and the prognosis of breast carcinoma.
