鼻咽粘膜上皮细胞如何癌变、异型增生及鳞状化生与癌变的关系如何,目前仍不十分清楚,本文从形态发生的角度探讨其相互关系。材料和方法鼻咽活检1049例,全部均存有粘膜上皮,无上皮者不包括在内。按活检有无癌组织分成癌组(783例)和非瘤组(266例)。切片常规染色,观察粘膜上皮的类型、增生、化生及早期癌变的情况。 How is the relationship between nasopharyngeal epithelial cells cancerous, dysplasia and squamous metaplasia and cancerous, is still not very clear, this article discusses their mutual relations from the perspective of morphogenesis. Materials and Methods 1049 cases of nasopharyngeal biopsy, all with mucosal epithelium, none of which were not included. The biopsy specimens were divided into cancer group (783 cases) and non-tumor group (266 cases). Slices were routinely stained to observe the type, hyperplasia, metaplasia, and early canceration of the mucosal epithelium.
