摘要
目的:寻找提高食管癌早期诊断准确率的方法。方法:本实验对41例食管癌患者进行食管拉网,取其脱落细胞,用PAP法进行脱落细胞β2微球蛋白(β2m)检测。结果:在41例食管癌病例中,均发现β2m完全丢失的阴性细胞(即肿瘤细胞),作出正确诊断,无1例假阴性;而常规细胞学方法,41例中有5例阴性,阳性率仅87.8%。结论:食管拉网脱落细胞β2m检测有很高的诊断准确率,可作为食管癌诊断、早期诊断和高危人群普查的有效检查方法。
Objective:To evaluate an accurate method for early diagnosis of esophageal cancer.Methods:detection of β 2 microglobulin(β 2m) negative exfoliative cells in 41 cases of esophageal cancer with PAP method.Results:β 2m negative exfoliative cells were considered to be the tumor cells,which were found in all 41 cases of esophageal cancer,wherear,in examination with routine cytological method,the positive rate was only 87.8%.Conclusions:The detection of β 2m negative exfoliated cells is of high diagnostic value in esophageal cancer.
