Triple-negative breast cancer (TNBC), defined as lacking expression of the estrogen receptor, progesterone receptor, and HER2, comprises approximately 15% of incident breast cancers and is over-represented among those with metastatic disease. There are several biologically distinct subtypes within TNBC. Although the incidence of BRCA mutations across all subsets of breast cancer is low, BRCA mutations are more common among those with TNBC and may have therapeutic implications. The general principles guiding the use of chemotherapy and radiation therapy do not differ dramatically between early-stage TNBC and non-TNBC.
三阴性乳腺癌(TNBC)定义为缺乏雌激素受体、孕激素受体和 HER2 的表达,约占新发乳腺癌的 15%,并且在转移性疾病患者中更为常见。TNBC 中有几种生物学上明显不同的亚型。尽管所有乳腺癌亚组的 BRCA 突变发生率都较低,但 TNBC 中 BRCA 突变更为常见,并且可能具有治疗意义。指导早期 TNBC 和非 TNBC 化疗和放疗使用的一般原则没有明显差异。
