In Korea, Cancer of the uterine Cervix is the most common gynecologic malignacy and leading cause of death in women. Cytologic screening for cancer of the cervix, specifically precancerous lesions, is generally accepted as being effective in
reducing
both incidence and mortality for cervical cancer. Due to the absence of a nation-wide mass screening program and national cancer registry program, the prevalance rate of cervical cancer and cervical intraepithelial neoplasia in the normal
population has
not been exactly evaluated in our country.
The purpose of this study is to investigate the efficacy of the cevical cytology as a screening tools for the cervcal cancer and to roughly estimate the prevalence of cervical cancer group of women visited our health care center.
Review of the cytologic smears from January 1, 1991 to December 31, 1993 revealed 14,505 cases with 484 abnormal cytology.
@ES The results were as follows ;
@EN 1. Of the women screened were the age of 20 years, 29.2% < 40 years, 33% <50 years, 25.1% >60, 9.0% <70, 0.8% ≥70 respectively.
2. Abnormal cytology rate was 3.34% including 2.50% of class II, 0.56% of class III, 0.24% of class IV and 0.24% of class V.
3. 3. Abnormal cytology rate increased with age. The proportion of women with abnormal cytology was highest in those age of years(5.1%). Class III was highest between ages 30 and 49 and class IV, V in those age of 60 years(1.0%).
4. 4. At the histopathologic evaluation of the biopsy specimens from the women with class III(40/81), 45(65.3%) had findings cocsistent with CIN(Cervical intraepithelial neoplasia) I or worse. Among the histopathologically evaluated women with
class
IV, V(29/41), 28(97%) had lesions worse than mild dysplasia ; 5 of these were found to have invasive cancer.
5. The prevalence rates of carcinoma in situ and invasive cancer for the past 3 years were 0.23%(33/14,505) and 0.03%(5/14,505).
