雄激素受体、Ki-67在三阴性乳腺癌中的表达以及与预后的关系

摘要/Abstract

摘要： 目的探讨雄激素受体和Ki-67在三阴性乳腺癌（TNBC）中的表达,并研究它们与患者预后的关系。方法选择了朝阳市中心医院2015年1月~2020年5月期间治疗的TNBC女性患者88例作为观察组,同时纳入了非三阴性乳腺癌（NTNBC）女性患者89例作为对照组。我们检测了AR和Ki-67的表达情况,并观察它们在TNBC中的表达差异,同时分析了它们与患者预后的关系。结果 AR在观察组的表达率低于对照组（P<0.05）,而Ki-67在观察组中的表达率高于对照组（P<0.05）。AR和Ki-67的表达均与肿瘤直径以及淋巴结转移个数有关（P<0.05）。COX回归分析显示,病理分级、淋巴结转移个数、AR和Ki-67表达情况是影响TNBC预后的独立影响因素(P<0.05)。结论 AR和Ki-67与TNBC的预后密切相关,AR阳性表达和Ki-67低表达的患者提示预后较好,生存时间更长。

Abstract: Objective To investigate the expression of androgen receptor (AR) and Ki-67 in triple-negative breast cancer, and to study their relationship with patients' prognosis. Methods Eighty-eight female TNBC patients treated at Chaoyang Central Hospital from January 2015 to May 2020 were included in the observation group, while 89 female NTNBC patients were included as a control group. We examined the expression of AR and Ki-67 and observed the differences in their expression in triple-negative breast cancer, and analysed their relationship with patients' prognosis. Results The expression rate of AR in the observation group was lower than that in the control group (P<0.05), while the expression rate of Ki-67 in the observation group was higher than that in the control group (P<0.05). The expression of AR and Ki-67 is related to tumor diameter and the number of lymph node metastases (P<0.05). COX regression analysis showed that pathological grade, number of lymph node metastases, AR and Ki-67 expression were independent influences on the prognosis of triple-negative breast cancer (P<0.05). Conclusion AR and Ki-67 were closely related to the prognosis of triple-negative breast cancer. Patients with positive AR expression and low Ki-67 expression suggested a better prognosis and longer survival time.
