Cervicovaginal cytology in an indigent population. Comparison of results for 1964, 1981 and 1989.
To evaluate the usefulness of cervicovaginal cytology in decreasing the incidence of cervical carcinoma in an indigent population, the cytologic findings from 10,000 consecutive smears in 1964 (when cytology screening started) were compared to the results of 10,000 consecutive smears in 1981 and 1989. There was a marked (statistically significant) decrease in invasive cervical squamous carcinoma at all ages between the first and later periods. Squamous carcinoma in situ showed a significant decrease beginning in patients under 40 in 1981. The number of atypias and mild dysplasias showed a proportional increase, from 2% in 1964 to 13.4% in 1981 to 21.8% in 1989, predominantly in young patients. These results reaffirm that cervicovaginal cytology remains the most inexpensive and effective diagnostic tool for the elimination of cervical cancer.
