Mass screening for cervical cancer in Miyagi prefecture has been taken chiefly by a cytological method since 1962.
The total number of women examined by our screening car from 1962 to 1970 was 131, 084, and smear-positive cases were 238 (0.19% of the total cases).
As a result of this program, 493 cases of dysplasia of cervix were detected. In these the cytologically smear-positive caseas were 39 (7.8%).
At the 1st screening for cervical cancer 46 were suspected as false positive cases. These cases were examined in our cancer clinic by means of a systematic technique including vaginal smear, colposcopy and punch biopsy.
Finally 5 cases revealed no cyto-histological disorders except for inflammation and metaplasia.
The smear-positive cases detected both the first and following second screening were rarely given benign lesions.
About 23% of smear-positive dysplasia was found of progression to carcinoma in situ or invasive carcinoma.
