三陰性乳癌(英語:Triple-negative breast cancer,缩写为TNBC),也称三阴性乳腺癌,是指缺乏雌激素受体英语Estrogen receptor(ESr或Er)、孕酮受体(Pr)表达与缺乏表皮生长因子受体-2(HER)过表达或者增殖的乳癌[1],临床上一般通过免疫组化确定[2]。这三个特征常见于其它乳癌中,却少见于此分型中[1],如激素治疗等在内的常见乳癌治疗方案往往针对这三类受体,因而三阴性乳癌患者身上起效[3]

三阴性作为一种侵袭性表型,主要表现为基底样或正常乳腺样肿瘤[2],90%为单灶性浸润性导管癌[2]。该型癌症易发转移,复发较多且较早,缺乏获批准的靶向治疗方法[3]。该型癌症具有高度异质性,因此可能并非单一疾病,而是不同疾病之集合[4],依据组织学、细胞起源、突变、转移潜能、疾病进展、治疗反应和临床结果等,还可以分出可以采取不同治疗策略的亚型[1][5],如针对BCRA突变的患者已经出现PARP抑制剂等靶向治疗药物[6][7][8]。不同亚型对药物的反应也不同,如病人无BRCA1/2突变或有肿瘤浸润淋巴细胞浓度增加,则已有试验证实卡铂联合紫杉醇进行新辅助英语Neoadjuvant therapy化疗效果更好[9][10]。对于不同亚型的预后也会有所差异,诺丁汉预后指数可以帮助进行预后判断,但需要更激进治疗者除外[11]。目前主要采取化疗对该癌症包括转移期在内各个阶段进行治疗[12]。在美国,超50%的可选择手术的患者选择了乳房切除术[3]

该型癌症多发于年轻女性,可能与BRCA1基因突变相关;特定族裔(非洲裔西班牙裔)等群体呈现高发,可能与较差社会经济地位相关[13]。该型癌症在美国乳癌病例中占15%左右[3],在亚洲的乳癌病例中占10-17%[5]
