Correlation between CD24 expression and its relation with Ki67,Bcl-2 in breast carcinoma / 国际外科学杂志

ABSTRACT

Objective To investigate the expression of CD24 and Ki67 in the invasive breast ductal car-cinoma tissues, so as to assess the role of CD24 protein in the carcinogenesis and progression of breast canc-er. Methods The expression of CD24 and Ki67, Bcl-2 was examined by immunohistochemically in 86 breast cancer specimens and 30 non-cancer specimens ( ElivisionTM Plus). The relationship between CD24 expression and Ki67, Bcl-2, patient age, tumor size, histopathologic grade, axillary lymphnode metastasis, and clinical stage of breast cancer was analyzed. Results In 86 eases of invasive breast ductal carcinoma, the positive incidences of CD24 was 87.2% (75/86), which distinguished apparently from those of the con-trol group( P <0.01 ). In breast carcinoma tissues, the expression of CD24 was positively related to axillary lymphnode metastasis(P <0.01 ), but was not related to patients age,tumor size, histopathologic grade and clinical stage(P>0.05). CD24 expression was positively related to Ki67 (P<0.01 ) and negatively relat-ed to Bcl-2(P>0.05). Conclusion CD24 expression was related to the proliferation, invasion and me-tastasis of breast cancer cells and it can serve as an important marker for predicting biological behavior and prognosis of tumors.
