[Study on the maintenance of the accuracy of cytological diagnosis in the mass screening of uterine cervical cancer].
We studied the effect of the centralized cervical cytological screening program in Shimane prefecture and obtained the following results. After the centralized screening system was introduced, the rate detection of dysplasia almost doubled. The detection rates for carcinoma in situ and invasive carcinoma of the uterine cervix increased from 0.042% to 0.047% and from 0.042% to 0.065%, respectively. The cases with Pap. class III, IV, and V decreased to a third on the centralized cytologic screening system. The false negative rates for carcinoma in situ and invasive carcinoma decreased from 20.0% to 17.9% and from 16.0% to 7.4%, respectively. We concluded that the accuracy of the cytological diagnosis was improved by the establishment of the centralized system.
