食管细胞学与活检诊断对比分析

对在食管癌高发区普查中诊断为重度增生的患者,进行食管拉网细胞学、内镜刷检细胞学与内镜活检组织学的复查,并对诊断结果进行对比。结果细胞学诊断与组织学诊断在癌前增生阶段的符合率较低。细胞学癌前增生检出率高于组织学。二者对于鳞癌的诊断符合率较高。提示:食管拉网细胞学检查适合于食管癌前病变的研究,并可作为早期食管癌诊断及筛选方法。

The contrast of the results between the cytologic and the histologic diagnoses of esophageal dysplasia and carcinomal

In high-risk area of esophageal cancer, a follow-up examination of 691 dysplasticsubjects found in mass survey of 1983 was made with balloon cytology. esophagoscopicbrush cytology and bloptic histology in 1987. It was revealed that diagnosticresults with these different methods for dysplasia were different. About 58%of cases of dysplasia were diagnosed with balloon cytology. 50% with brushcytology. and 29 % with bioptic histology. But for the carcinoma cases. about 30% werefound with balloon cytology. 20% with brush cytology, and 25% with bioptic histology.The analysis mentioned above suggests that balloon cytology be good at screening inmass survey, and it should be combined with brushing smear and endoscepic biopsyto elevate the rate of correct diagnosis. The significance of nearcarcinoma cells fordetecting early carcinoma of the esophagus is discussed.
