不同病理类型的鼻咽癌(NPC)其生物学行为不同。不同地区的鼻咽癌,其病理类型分布等也有差异。本文就贵州省1964——1985年收治的1722例NPC中有明确病理分类、资料完整的1435例,按不同病理类型,对其某些临床及流行学特点进行研究。资料与方法病理分类本组根据1979年长沙会议制定的命名和分类方案(二),参照有关资料,将NPC分为三大类即一.分化好的鼻咽癌(高分化类):包括鳞癌Ⅰ,Ⅱ级,分化好的腺癌,腺样囊性癌,腺泡状腺癌。二.分化差的鼻咽癌(低分化类):包括鳞癌Ⅲ级,分化差的腺癌、泡状核细胞癌(包括旧称大园细胞癌,淋巴上皮癌),梭形细胞癌等。三.未分化鼻咽癌。临床分期所有病例均按1981年广州会
Different pathological types of nasopharyngeal carcinoma (NPC) have different biological behaviors. Nasopharyngeal carcinomas in different regions also differ in their pathological type distribution. In this paper, there were 1,435 NPCs with clear pathological classification and complete data in 1,722 cases of NPC admitted in Guizhou Province from 1964 to 1985. According to different pathological types, some clinical and epidemiological characteristics were studied. Materials and Methods Pathological classification According to the naming and classification scheme (2) developed at the 1979 Changsha conference, referring to relevant data, the NPCs were divided into three categories: 1. Well-differentiated nasopharyngeal carcinoma (highly differentiated): including scales Grades I, II, well-differentiated adenocarcinoma, adenoid cystic carcinoma, adenocarcinoma of the adenocarcinoma. 2. Poorly differentiated nasopharyngeal carcinoma (low differentiation): Includes squamous cell carcinoma grade III, poorly differentiated adenocarcinoma, vesicular nucleus cell carcinoma (including old cell carcinoma, lymphoid epithelial carcinoma), and spindle cell carcinoma. Undifferentiated nasopharyngeal carcinoma. All cases of clinical staging were based on the 1981 Guangzhou Conference.
