Abstract: | AIM: To explore the protein levels of chemokine receptor 7 (CCR7) and vascular endothelial growth factor (VEGF)-C in breast carcinoma, and to investigate the effects of CCR7 and VEGF-C on prognosis of breast carcinoma. METHODS: The protein expression levels of CCR7 and VEGF-C in the breast carcinoma tissues and normal breast tissues were detected by the method of immunohistochemistry. At the same time, the relationship between clinicopathologic characteristics and the protein expression of CCR7 and VEGF-C in the breast carcinoma tissues was analyzed. The relationship between the protein expression of CCR7 and VEGF-C and survival time of the breast cancer patients was estimated by Kaplan-Meier method.RESULTS: The positive expression rates of CCR7 and VEGF-C in the breast carcinoma tissues were significantly higher than those in the normal breast tissues (P<0.01). A positive correlation was observed between the protein expression of CCR7 and the protein expression of VEGF-C in the breast carcinoma tissues (r=0.613, P<0.01). The protein expression of CCR7 and VEGF-C was correlated with lymph node metastasis and TNM stage (P<0.05), but both were not related to patients' age, primary tumor size, estrogen receptor and progesterone receptor. The survival time of the patients with CCR7 and VEGF-C positive expression was significantly shorter than that of the patients without the expression (P<0.05).CONCLUSION: The positive expression of CCR7 and VEGF-C proteins is associated with the prognosis of breast cancer, and combined detection of CCR7 and VEGF-C protein expression levels may be helpful to judge the prognosis of breast cancer. |
