Relationship between expression of CXCR7 and NF-κB in breast cancer tissue and occurrence of breast cancer and lymphatic metastasis.

UNLABELLED

It is designed to discuss the relationship between the expression of chemokine receptor 7 (chemokine receptor 7, CXCR7) and nuclear transcription factor-κB (nuclear factor kappa B, NF-κB) and the occurrence of the breast cancer and lymphatic metastasis.

METHOD

80 samples were excised and confirmed as breast cancer through our hospital pathology from January 2014 to December 2016 and tumor tissues and normal mammary tissues 2 cm from the tumor edges were taken as an experimental group and a control group, respectively. The method of immunohistochemical is utilized to test the expression of CXCR7 and NF-κB in the breast cancer tissue, compared with the para-carcinoma tissue, and analyze its relevance with the clinicopathologic features of the breast cancer tissue, such as tumor size, TNM staging, lymphatic metastasis and other conditions.

RESULTS

both CXCR7 and NF-κB were highly expressed in the breast cancer tissue, the positive rate was significantly higher that that of paracancerous normal tissues, and the difference was statistically significant. And the expressions of CXCR7 and NF-κB were related to TNM staging of the breast cancer and lymphatic metastasis and unrelated to the tumor size, age, and expressions of ER, PR and HER2.

CONCLUSION

both CXCR7 and NF-κB are related to the malignant grade of the breast cancer and lymphatic metastasis, which may be regarded as in important indicator to judge the prognosis of the breast cancer and be expected to be the new target of curing part of the breast cancer.
