乳腺癌作为高度分子异质性疾病,根据雌、孕激素受体及Her-2的表达可分为4型。研究显示不同的分型具有明显不同的临床特征,根据分子分型指导患者接受化疗、内分泌治疗或靶向治疗。随着对其研究的深入,越来越多的报道显示分子分型可以指导乳腺癌的放疗。
Breast cancer as a highly heterogeneous disease, according to the estrogen, progesterone receptor and Her-2 expression can be divided into 4 types. Studies have shown that different subtypes have significantly different clinical characteristics, and guided patients to chemotherapy, endocrine therapy, or targeted therapy based on molecular typing. With the deepening of its research, more and more reports show that molecular typing can guide breast cancer radiotherapy.
