OBJECTIVE: To investigate the expressions of Survivin protein and nm23 protein and the relationship among the expressions and axillary lymph node metastasis in breast cancer.
METHODS: The expression of Survivin and nm23 in 80 cases of breast cancer tissues were detected by immunohistochemistry SP method, and their correlation with axillary lymph node metastasis and 5-year disease free survival (DFS) were analysed.
RESULTS: Survivin protein positive expression rate was 68.75% (55/80) in breast cancer tissues, which had positive correlation with the axillary lymph nodes metastasis but negative correlation with 5 years FS (P < 0.05); nm23 protein expression had negative correlation with the axillary lymph nodes metastasis but positive to 5 years FS (P < 0.05). Survivin and nm23 proteins expression had no obvious correlation with the breast cancer pathology type, patient age and clinical stage (P > 0.05).
CONCLUSION: The anti-apoptosis effect of Survivin protein and the anti-metastasis effect of nm23 protein may be important in the occurrence and advancement of breast cancer, suggesting that it may be a new indicator of prognostic and judgement in breast cancer.
