Evaluation of High-Risk Human Papillomavirus Testing in Women with Atypical Squamous Cells of Undetermined Significance to Detect Cervical Intraepithelial Neoplasia

Introduction We retrospectively examined the changes in the management and outcomes of the cases with atypical squamous cells of undetermined significance (ASC-US) according to the Bethesda system (TBS). Materials and Methods Between May 2009 and December 2018, 432 cases with ASC-US were retrospectively examined for the implementation of high-risk human papillomavirus (hrHPV) testing and/or cervical biopsy and clinical courses. Results The hrHPV testing was performed in 277 cases (64.1%). Of these, there were 80 with positive hrHPV (28.9%). Of the 80 cases, cervical biopsy was performed in 71 (88.9%) cases based on the finding of colposcopy. Cervical intraepithelial neoplasia (CIN) was diagnosed in 55 cases (77.4%). The sensitivity, specificity, positive predictive value, and negative predictive value of CIN diagnosis by hrHPV testing in cases of ASC-US were 72.5, 95.0, 88.7, and 86.3%, respectively (p < 0.01). Conclusion The conducting of hrHPV test on women who were evaluated as ASC-US according to TBS affirmed its clinical usefulness.
