Cytologic Screening for Cervical Cancer in the Florence District

Abstract

During the years 1970–1978, 213,575 women living in the Florence District had at least one cytologic smear. The overall incidence ratios were: dysplasia 1.09 ±, carcinoma «in situ » 1.25 ±, invasive carcinoma 1.01 ±. Age of the women attending the service, and incidence ratios according to age groups are examined. Incidence ratios in women who had previous negative smears are calculated; these values seem to fit well with a «false negative model». These results are compared with those reported by other authors, and indications for a new kind of program are suggested.
