Expressions of Estrogen Receptor,Progestogen Receptor,Cerb-B2,and Ki67 Index in the Simple Mucinous Carcinoma of the Breast / 中国医学科学院学报

ABSTRACT

<p><b>OBJECTIVE</b>To approach the expressions of estrogen receptor (ER),progestogen receptor (PR),Cerb-B2,and Ki67 index in simple mucinous carcinoma of the breast and their clinical significance.</p><p><b>METHODS</b>The clinicopathological data of 72 patients with simple mucinous carcinoma of the breast who were treated in our hospital from 1997 to 2012 were retrospectively studied. Expressions of ER,PR,Cerb-B2,and Ki67 index and their relationship with clinical characteristics were analyzed.</p><p><b>RESULTS</b>Nine patients had lymph node metastasis. Expressions of ER,PR,and Cerb-B2 were 77.8%,69.4%,and 3.1%,respectively. The expressions of ER,PR,and Cerb-B2 showed no correlation with age,menstrual status,and axillary lymph node metastasis (P>0.05). The expression of ER was correlated with tumor diameter (P=0.008) while the expression of PR and Cerb-B2 showed no such correlation.</p><p><b>CONCLUSIONS</b>High ER or PR expression and low Cerb-B2 expression predict good prognosis in patients with simple mucinous carcinoma of the breast. Combined detection of ER,PR,Cerb-B2,and Ki67 index may help to improve the multidisciplinary management of simple mucinous carcinoma of the breast.</p>
