目的探讨提高住院鼻咽癌早诊率的方法和途径.方法结合社区服务,随机与周边市县合作定期进行人群鼻咽癌血清学筛查,分析同期首次住院病例来源100例以上11市县2436例鼻咽癌资料.结果未筛查过的四市县住院鼻咽癌患者773例,早诊率14.05%,低于筛查过1~2次的4市县(住院986例,早诊率18.05%),P<0.01;筛查过3次以上的3市县住院者677例,早诊率30.43%.结论定期对病例来源较多的市县进行人群鼻咽癌筛查是提高住院鼻咽癌早诊率的方法和途径. 相似文献

以往,人们多用鼻咽部组织进行鼻咽粘膜癌前病变形态学的研究。本文报告用免疫酶法测定病人VCA—IgA抗体,对阳性者的鼻咽部活体组织粘膜各种病变进行观察,试图了解其各种病变在鼻咽癌发生上的意义。材料和方法我们分别于1978年6月,1979年1月,1980年1月,在苍梧县对30岁以上人群应用免疫酶法测定血清VCA—IgA抗体,进行鼻咽癌普查,以VCA—IgA抗体滴度1:2.5 相似文献

目的:应用即用型快捷免疫组化MaxvisionTM微波修复抗原法检测肿瘤耐药基因。方法:随机选取100例乳腺癌组织标本,采用微波加热修复抗原法进行肿瘤基因检测。结果:100例乳腺癌中PgP、GST-л和ToPo的阳性表达率分别29/100、58/100和68/100,结果检测表明29%患者PgP阳性对阿霉素、长春新碱、VP16及紫杉醇等有一定耐药。58%患者GST-л阳性,提示对阿霉素、顺铂、氮介耐药。68%的患者ToPo阳性提示可用阿霉素类药。结论:检测肿瘤细胞的耐药基因,可指导乳腺癌的临床化疗前筛选出不具有耐药的联合用药方案。 相似文献

The immuno-enzymaticmethod was used andserLrm VCA-IgA antibodywas detected in mass
surveys. The relationship between the antibody level
and nasopharyngeal carcinoma (NPC) and non-NPC
lesions were studied. The results showed that in the
NPC or non-NPC antibody positive group, the
occurrence of atypical hypereplasia or metaplasia was
higher than in the antibody negative group of non
NPC patients and the antibody level in NPC atypical
hyperplasia or metaplasia was higher than in simple
hyperplasia or metaplasia, the increase being related
to the mucous lesion stage.
Thus we presume that NPC is closely related
to atypical hyperplasia or metaplasia and that EB
virus may play an important role in nasopharyngeal
mucosal transformation or the development of mali
gnancy. 相似文献
