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.
