To assess the value of mass-screening for uterine cervical cancer, we compared data obtained from a "model area" with findings obtained from the whole of Shimane Prefecture. The factors given attention were: Screening ratio, detection ratio and mortality directly related to cancer of the uterine cervix. These data were obtained from 1976-1980. The results are as follows: Screening ratio and mortality rates were 35.7% and 7.8% respectively, in the model area and 8.4% and 11.5% respectively, in Shimane Prefecture. Four years after setting up the "model area", the mortality rate for uterine cervical cancer reached zero. The ratio of cancer detection in the "model area" was 0.204%, that is about twice that in Shimane Prefecture. The ratios of detection of severe dysplasia, carcinoma in situ and infiltrative carcinoma were higher in the "model area" than in Shimane Prefecture. Detection of severe dysplasia and carcinoma in situ was significantly high in the "model area". Therefore, to reduce the mortality rate for cervical cancer, the CAI should be over 350.
为评估子宫颈癌大规模筛查的价值，我们将从一个“示范区”获得的数据与从岛根县全县获得的结果进行了比较。所关注的因素包括：筛查率、检出率以及与子宫颈癌直接相关的死亡率。这些数据取自1976年至1980年。结果如下：示范区的筛查率和死亡率分别为35.7%和7.8%，而岛根县的筛查率和死亡率分别为8.4%和11.5%。设立“示范区”四年后，子宫颈癌死亡率降为零。“示范区”的癌症检出率为0.204%，约为岛根县的两倍。“示范区”中重度发育异常、原位癌和浸润性癌的检出率高于岛根县。重度发育异常和原位癌在“示范区”的检出率显著较高。因此，为降低宫颈癌死亡率，细胞学涂片检查指数（CAI）应超过350。
