癌症是一种包含肿瘤细胞本身和宿主基质细胞多种成分的全身性疾病。现在很清楚,肿瘤微环境中的基质细胞在癌症发展中起着重要作用。通过反应性基质细胞影响癌细胞的分子事件可以被定义,从而确定生物标志物和治疗靶点。癌症相关成纤维细胞(CAFs)构成了癌症基质的大部分,并影响肿瘤微环境,从而促进癌症的发生、血管生成、侵袭和转移。在乳腺癌中,CAFs不仅促进肿瘤进展,而且诱导治疗抵抗。因此,靶向caf提供了一种新的方法来控制具有治疗耐药性的肿瘤。本文综述了目前对乳腺癌肿瘤基质的认识,特别强调了CAFs的作用和CAFs的治疗意义。此外,其他基质成分如内皮细胞、巨噬细胞和脂肪细胞在乳腺癌中的作用也进行了讨论。最后,我们描述了生物标记物,将患者分类为特定的和确认的亚型,以进行个性化治疗。
Cancer is a systemic disease encompassing multiple components of both tumor cells themselves and host stromal cells. It is now clear that stromal cells in the tumor microenvironment play an important role in cancer development. Molecular events through which reactive stromal cells affect cancer cells can be defined so that biomarkers and therapeutic targets can be identified. Cancer-associated fibroblasts (CAFs) make up the bulk of cancer stroma and affect the tumor microenvironment such that they promote cancer initiation, angiogenesis, invasion, and metastasis. In breast cancer, CAFs not only promote tumor progression but also induce therapeutic resistance. Accordingly, targeting CAFs provides a novel way to control tumors with therapeutic resistance. This review summarizes the current understandings of tumor stroma in breast cancer with a particular emphasis on the role of CAFs and the therapeutic implications of CAFs. In addition, the effects of other stromal components such as endothelial cells, macrophages, and adipocytes in breast cancer are also discussed. Finally, we describe the biologic markers to categorize patients into a specific and confirmed subtype for personalized treatment.
