The factors associated with the progression of ductal carcinoma in situ (DCIS) to invasive breast cancer are poorly understood. Many studies of this subject focus on the role of molecular and genetic alterations in the neoplastic epithelial cells. However, emerging evidence suggests that transition from DCIS to invasive cancer is strongly dependent upon alterations in the microenvironment. The potential roles of myoepithelial cells and of stromal-epithelial interaction are of particular interest in this regard.
乳腺导管原位癌(DCIS)进展为浸润性乳腺癌的相关因素尚不清楚。许多关于该主题的研究聚焦于肿瘤上皮细胞中分子和基因改变的作用。然而,新出现的证据表明,从DCIS向浸润性癌的转变强烈依赖于微环境的改变。在这方面,肌上皮细胞以及基质-上皮相互作用的潜在作用尤其令人关注。
