一、普通人群中的鼻咽癌普查 1970—1972年期间,在广东省对10岁以上的436,786居民用鼻咽镜检查鼻咽腔,并对全身各部位进行肿瘤普查。在所发现的174例鼻咽癌中(表1),80例(45.9％)是新发现的,其中43例为Ⅰ期病人(53.75％),基本上无症状。普查中的Ⅰ期鼻咽癌发现率较专科医院门诊所见的Ⅰ期鼻咽癌(本院1979.9—1981.1期间Ⅰ期占6％)高7.96倍(表2)。中山县建立防癌网以来,Ⅰ、Ⅱ期鼻咽癌的百分比从1970年的44.93％提高到1975年的68.86％。
I. General survey of nasopharyngeal carcinoma in the general population In the period from 1970 to 1972, 436,786 residents over 10 years of age were examined with nasopharyngeal examination in the nasopharynx in Guangdong, and tumors were examined in various parts of the body. Of the 174 nasopharyngeal carcinomas found (Table 1), 80 (45.9%) were newly discovered, of which 43 were stage I (53.75%) and were essentially asymptomatic. The detection rate of stage I nasopharyngeal cancer in the census was 7.96 times higher than that of stage I nasopharyngeal carcinoma (6% of stage I from 1979.9 to 1981.1 during this period) (see Table 2). Since the establishment of anti-cancer nets in Zhongshan County, the percentage of stage I and II nasopharyngeal cancers has increased from 44.93% in 1970 to 68.86% in 1975.
