Abstract

The objective of this study was to find the risk factors of having high-grade cervical intraepithelial neoplasia/invasive carcinoma in women with atypical glandular cells of undetermined significance (AGUS) smears. A retrospective study of the women with AGUS smears during the 3-year period was performed to determine the correlation between the suspected variables and the histopathologic diagnoses. Among 44,071 smears performed, 119 (0.27%) smears were reported as AGUS. Colposcopies were performed in 102 (88.7%) cases, and high-grade cervical intraepithelial neoplasia/invasive carcinoma was found in 18 (17.6%) cases. Among the following variables, which included age, menopausal status, hormonal contraception, history of previous Pap smears, medical diseases, clinical symptoms, and subclassification of AGUS, both hormonal contraception and AGUS favor neoplasia were risk factors with an odds ratio of 5.4 and 5.0, respectively. Although clinical symptoms seemed to be a significant variable in univariate analysis, it appeared as a confounding factor in multivariate analysis.
