作者采用组织学、显微镜光度计和免疫组织化学的方法,描述了鼻咽癌旁原位癌的组织病理学特征及其在肿瘤组织发生和演进中的作用. 作者将鼻咽癌旁原位癌分为柱状和鳞状两型,比较了它们各自的组织学和细胞学特点. 本文认为:在浸润性鼻咽癌出现之前已经发生了一系列的改变,而原位癌则是癌症的组织发生和肿瘤演进过程中关键性的一步.已呈异型性改变的储备细胞或未分化中间细胞恶变为原位癌细胞;然后在未知因素的影响下,原位癌细胞呈侵袭性而形成浸润性鼻咽癌.
The authors used histology, microscopy, and immunohistochemical methods to describe the histopathological features of paranasal carcinoma in situ of nasopharyngeal carcinoma and its role in tumorigenesis and progression. There are two types, columnar and squamous, and their respective histological and cytological features are compared. This article believes that a series of changes have occurred before invasive nasopharyngeal carcinoma, while carcinoma in situ is the tissue of cancer. And a critical step in the evolution of tumors. Reserve cells or undifferentiated intermediate cells that have been abnormally transformed into cancer cells in situ; then under the influence of unknown factors, in situ cancer cells are invasive and form infiltrating noses. Pharyngeal cancer.
