尽管乳腺肿瘤的组织学分级及鉴别诊断可以在常规的ＨＥ切片中进行,然而,这不可避免地会带有主观偏面性,故提出具有可重复性的肿瘤定量组织学评估具有重要意义[1,2]。本研究拟在乳腺原位癌及浸润性癌中,进行定量形态学比较,并在伴有或缺乏侵袭性成分的原位癌癌变细胞间特征的比 Although the histological grade and differential diagnosis of breast tumors can be performed in conventional HE slices, this inevitably leads to subjective deviated facial features. Therefore, it is important to propose quantitative histological assessment of reproducible tumors.[1] ,2]. This study intends to compare the quantitative morphological characteristics of in situ carcinoma and invasive carcinoma of the breast with the presence or absence of invasive components in in situ carcinomas.
