Abstract

Abstract:

Objective

To investigate the expression of chemokine receptor CXCR4 in breast cancer and its correlation with lymphatic and distant metastasis and prognosis.

Methods

Samples of 84 cases of normal breast tissues,84 cases of breast cancer tissues and 43 cases of regional lymph node metastasis were obtained from the Second Affiliated Hospital of Fujian Medical University from January,2000 to December,2002.The expression of chemokine receptor CXCR4 in these samples was detected with immunohistochemistry.The results were processed with Chi-square test for paired numeration data and log-rank test for survival rate.

Results

The positive rates of CXCR4 expression in normal breast tissues,breast cancer tissues and regional lymph node metastasis were 11.9%,53.6%and 74.4%,respectively.Positive expression of CXCR4 was correlated with lymph node metastasis,clinical staging and HER-2 status (P＜0.05),but not with the age of patients,tumor size,ER,PR status and differentiation.The level of CXCR4 expression in the distant metastasis group(74.1%)was far higher than that in the non-metastasis group(43.9%).The 5-year survival rate in the group with positive expression of CXCR4(66.7%)was lower than that in the group with negative expression of CXCR4(87.2%,P＜0.05).

Conclusion

Positive expression of CXCR4 in breast cancer is significantly associated with lymphatic metastasis and distant metastasis,so can be used as a potential predictive factor for prognosis of breast cancer.
