摘要:

目的 探讨雄激素受体(androgen receptor,AR)在早期三阴性乳腺癌(triple negative breast cancer,TNBC)中的表达与临床病理特征及预后的关系。方法 回顾分析 2010 年 1 月至 2014 年 12 月在十 堰市太和医院甲乳外科收治的185例早期TNBC患者的病例资料,通过免疫组化方式检测AR的表达情况, 分析AR表达与临床病理指标之间的关系以及AR对患者预后的影响。结果 185例早期TNBC患者中,AR 阳性表达54例(29.2%)。较AR 阴性患者,AR 阳性患者具有组织学分级低、肿瘤直径小、淋巴结转移率低、 p53阳性率低及Ki⁃67低表达的特征(P < 0.05)。AR表达情况与年龄、月经状态、放化疗及脉管癌栓无相关性 (P > 0.05)。中位随访63个月,41例发生复发转移(22.2%),死亡27例(14.6%)。AR阳性患者较AR阴性患者 具有更好的无病生存期和总生存期(P < 0.05),且多因素分析显示 AR 阳性是患者总生存期独立的影响因 素。结论 早期 TNBC 患者中 AR 阳性表达与组织学分级低、肿瘤直径小、Ki⁃67 增殖指数低等预后良好临 床病理指标存在关联性,且是总生存期独立的保护因素,提示AR可能成为TNBC的治疗靶点和预后指标。

Abstract:

Objective To determine the expression of androgen receptor(AR)in early triple negative breast cancer(TNBC)and its relationship with clinicopathologic features and prognosis. Methods The clinical data on 185 patients with early TNBC treated in Taihe Hospital from January 2010 to December 2014 were analyzed retrospectively. The relationship between AR expression and the clinicopathological features was analyzed based on the results of immunohistochemistry,and the influence of AR on prognosis was investigated. Results Of the 185 patients diagnosed with early TNBC,54(29.2%)were AR positive. As compared with AR negative patients,AR positive patients had lower histological grade,smaller tumor size,lower lymph node metastasis rate,and lower expressions of p53 and Ki⁃67(P < 0.05). AR expression was not associated with age,menstruation,vascular cancer thrombus,chemotherapy and radiation(P > 0.05). During a follow⁃up of median 63 months,41 cases(22.2%) developed recurrence and 27(4.6%)were dead. The patients with positive AR had longer disease⁃free survival and overall survival than those with negative AR(P < 0.05). The multivariate Cox analysis showed that AR was an in⁃ dependent risk factor affecting the overall survival in patients with TNBC(P < 0.05). Conclusions AR⁃positive expression in early TNBC patients was associated with good prognosis clinicopathological indicators includinglower histological grade,smaller tumor diameter and lower Ki ⁃67 proliferation index. It was an independent prognostic factor,suggesting that AR may be a new prognostic biomarker and potential therapeutic target for early TNBC.
