Triple-negative breast cancer (TNBC) is an aggressive subgroup of breast cancer lack of effective target therapy. This study was to investigate the prognostic role of p53 and Ki-67 in 156 cases of TNBC patients. Logistic regression analysis was used to examine the association between clinical parameters and recurrence. Univariate and multivariate analyses were used to examine the association between clinical characteristics and disease-free survival (DFS) or overall survival (OS). Survival analyses using the Kaplan-Meier method were performed to examine the association between p53/Ki-67 and DFS and OS. Our data showed that p53 was positive in 71.3% and the Ki-67 high index was in 82.8% of TNBC. Elevated p53 and Ki-67 were associated with histological grade. The tumor size, lymph node involvement, and p53 expression are associated with risk of recurrence. Tumor size, lymph node involvement, family history, Ki-67 and p53 are independent variables associated with either DFS or OS. TNBC patients with positive p53 or Ki-67 high index or family history of cancer have a significant association with worse prognosis. This study suggests that p53, Ki-67 and family history are useful prognostic markers in TNBC.
三阴性乳腺癌(TNBC)是乳腺癌中侵袭性较强的一个亚组,缺乏有效的靶向治疗方法。本研究旨在探讨p53和Ki-67在156例TNBC患者中的预后作用。采用逻辑回归分析来检验临床参数与复发之间的关联。单因素和多因素分析用于检验临床特征与无病生存期(DFS)或总生存期(OS)之间的关联。采用Kaplan-Meier方法进行生存分析,以检验p53/Ki-67与DFS和OS之间的关联。我们的数据显示,71.3%的TNBC患者p53呈阳性,82.8%的患者Ki-67高表达。p53和Ki-67升高与组织学分级相关。肿瘤大小、淋巴结受累情况和p53表达与复发风险相关。肿瘤大小、淋巴结受累情况、家族史、Ki-67和p53是与DFS或OS相关的独立变量。p53阳性或Ki-67高表达或有癌症家族史的TNBC患者预后明显较差。本研究表明,p53、Ki-67和家族史是TNBC有用的预后标志物。
