Abstract:ObjectiveTo study the expression of Lin28B in triple-negative breast cancer(TNBC)and its clinical significance.MethodsFrom January 2008 to December 2013,96 patients with TNBC treated in our hospital were selected as observation objects.The expression of Lin28B protein in cancer tissue and para-carcinoma tissue was detected by immunohistochemical method in order to analyze the correlation between Lin28B protein expression and pathological characteristics in patients with TNBC.ResultsThe positivity rate of Lin28B from cancer tissue was 70.8%and in para-carcinoma tissue,its positivity rate was 29.2%,which was displayed statistical difference(P<0.05).There was no relationship between Lin28B protein expression and age,the stage of tumor,and the condition of menstruation of patients(P>0.05).The expression of Lin28B protein was positively correlated with tumor differentiation degree,distal metastasis,lymph node metastasis,Ki67 expression(P<0.05).ConclusionThe expression of Lin28B is related to the occurrence and development of TNBC,and may affect the development of disease and prognosis of patients.
