Triple-negative breast cancer (TNBC) is an aggressive breast type of cancer with no expression of estrogen receptor (ER), progesterone receptor (PR), and human epidermal growth factor receptor-2 (HER2). It is a highly metastasized, heterogeneous disease that accounts for 10-15% of total breast cancer cases with a poor prognosis and high relapse rate within five years after treatment compared to non-TNBC cases. The diagnostic and subtyping of TNBC tumors are essential to determine the treatment alternatives and establish personalized, targeted medications for every TNBC individual. Currently, TNBC is diagnosed via a two-step procedure of imaging and immunohistochemistry (IHC), which are operator-dependent and potentially time-consuming. Therefore, there is a crucial need for the development of rapid and advanced technologies to enhance the diagnostic efficiency of TNBC. This review discusses the overview of breast cancer with emphasis on TNBC subtypes and the current diagnostic approaches of TNBC along with its challenges. Most importantly, we have presented several promising strategies that can be utilized as future TNBC diagnostic modalities and simultaneously enhance the efficacy of TNBC diagnostic.
三阴性乳腺癌(TNBC)是一种侵袭性乳腺癌,其雌激素受体(ER)、孕激素受体(PR)和人表皮生长因子受体 2(HER2)均不表达。它是一种高度转移性、异质性疾病,占所有乳腺癌病例的 10-15%,与非 TNBC 病例相比,其治疗后五年内的预后较差且复发率较高。TNBC 肿瘤的诊断和分型对于确定治疗选择以及为每个 TNBC 患者制定个性化、靶向药物至关重要。目前,TNBC 的诊断是通过影像学和免疫组织化学(IHC)的两步程序进行的,这两个程序都依赖于操作者,并且可能耗时较长。因此,迫切需要开发快速和先进的技术来提高 TNBC 的诊断效率。本文综述了乳腺癌的概述,重点介绍了 TNBC 亚型以及目前 TNBC 的诊断方法及其挑战。最重要的是,我们提出了几种有前途的策略,可以作为未来 TNBC 诊断方式,同时提高 TNBC 诊断的效果。
