目前,人们对宫颈、食管和膀胱等处原位癌的组织病理学的了解已经达到了一定的深度,但是有关鼻咽原位癌的研究,还几乎是空白,至今尚未有专题报道。即使是鼻咽癌旁原位癌,虽然有些作者曾在文章中提及,但还未见有系统的论述。这类病变的组织病理学特征,也缺乏详细的观察。本文以观察大量鼻咽活检材料为基础,探讨这一问题。材料和方法作者收集并复查了1975～1984年10年内所见的鼻咽活检4,173例。其中见到鼻咽癌者2,742例,未见癌者1,431例。在2,742例鼻咽癌的活检切片中,除了见到浸润性癌巢外,同时见到癌旁原位癌者64例。
At present, the understanding of the histopathology of in situ carcinoma of the cervix, esophagus and bladder has reached a certain depth, but the research on nasopharyngeal carcinoma in situ is almost blank, and there have been no special reports. Even if the cancer is next to nasopharyngeal carcinoma, although some authors have mentioned it in the article, there is no systematic discussion. The histopathological features of these lesions also lack detailed observations. This article explores this issue based on the observation of a large number of nasopharyngeal biopsy materials. Materials and Methods The authors collected and reviewed 4,173 cases of nasopharyngeal biopsy seen during the 10 years from 1975 to 1984. Among them, 2,742 cases of nasopharyngeal cancer were seen, and 1,431 cases of cancer were not seen. In 2,742 cases of biopsy specimens of nasopharyngeal carcinoma, in addition to invasive cancer nests, 64 cases of cancer adjacent to cancer were also seen.
