Abstract:
Purpose To investigate the expression of high mobility group protein Al (HMGA1) and C-X-C chemokine receptor 4 (CXCR4) in breast invasive ductal carcinoma and its clinical significance. Methods Immunohistochemical method was used to detect the expression of HMGA1 and CXCR4 in 105 cases of breast invasive ductal carcinoma and 80 cases of breast adenosis. The correlation between HMGA1 and CXCR4 expression and clinicopathological features was analyzed. Results The positive rate of HMGA1 and CXCR4 in breast invasive ductal carcinoma was significantly higher than that of breast adenosis(77.14％ vs 26.25％, 73.33％ vs 23.75％ ), the difference was statistically significant (P＜ 0.001). There was no significant correlation between HMGA1 and CXCR4 expression in breast cancer tissues (r = 0.104, P =0.289), suggesting that the expression of them were independent of each other. The combined detection of HMGA1 and CXCR4 could improve the sensitivity of diagnosis of (either positive) and specificity of(both positive). The positive rate of CXCR4 in PR positive breast cancer (87.5％ ) was higher than that in PR negative(60.0％ ), the difference was statistically significant (P =0.008) Conclusion HMGA1 is highly expressed in breast invasive ductal carcinoma, and CXCR4 expression is mainly low in breast invasive ductal carcinoma. HMGA1 and CXCR4 have higher sensitivity, and the combined detection of them can significantly improve the sensitivity and specificity of breast cancer diagnosis. The high expression of HMGA1 and CXCR4 in breast cancer has a certain clinical significance for the diagnosis and prognosis of breast cancer, which is expected to provide a new theoretical basis for the diagnosis and treatment of clinical breast cancer.
