Objective To assess the management chosen by gynecologists after atypical squamous cells (ASCs) cytology results, and to evaluate the outcomes of these cases in Brazilian women. Methods A prospective observational study evaluated the initial management offered by the gynecologist in the case of 2,458 ASCs cytology results collected between January of 2010 and July of 2016. The outcomes of the cytology, high-risk human papilloma virus (HR-HPV) test and histology were compared in two subgroups: atypical squamous cells of undetermined significance (ASC-US) and atypical squamous cells-cannot exclude high-grade squamous intraepithelial lesion (ASC-H). Results In many cases of ASC-US (36.97%) and ASC-H (40.50%), no clinical actions were taken. Cytology was the most frequent follow-up chosen, including for cases of ASC-H, which goes against the conduct recommended in the national guideline. In women over 30 years of age, the period of time elapsed between an ASC-US result and a new cytology was in 13.03 months, in disagreement with the national guideline recommendations (p < 0.0001). Negative for intraepithelial lesions or malignancy (NILM) cytologic (p = 0.0026) and histologic (p = 0.0017) results in the follow-up were associated with prior ASC-US, while negative results for ASC-H were cytologically (p < 0.0001) and histologically associated with high-grade squamous intraepithelial lesion (HSIL) (p < 0.0001). Two invasive cervical carcinomas (ICCs) were found in the follow-up for ASC-H, and there was a statistically significant association (p = 0.0341). A positive HR-HPV test was associated with ASC-H (p = 0.0075). Conclusion The data suggest that even for a population of Brazilian women assisted at private clinics, the national guidelines recommendations for ASCs results are not followed.

Automated Screening

Introduction: Automated screening of Thin Prep® Papanicolaou Tests has become increasingly common in clinical practice. Increased productivity has initiated laboratory use of the Thin Prep® Imaging System (TIS). Increased sensitivity is a potential additional benefit of TIS. Published studies have shown an increase in discovery of dysplastic cells. This study evaluates the effect of TIS on the incidence of atypical squamous cells high-grade squamous intraepithelial lesion not excluded (ASC-H) and high-grade squamous intraepithelial lesion (HGSIL) results on Thin Prep® Pap Tests by comparing TIS-assisted and manual screening findings and the diagnoses on subsequent follow-up in a screening population over a 1-year time period. Materials and Methods: A compilation of all ASC-H and HGSIL cases was prepared by conducting a computerized search over a 1-year period (7/06-6/07). The accumulated cases include Thin Prep Pap tests that were both TIS and manually screened. Follow-up results of cytologic and histologic cervical specimens were obtained for a time period extending to 2010. Interpretation utilizing TIS was in place 10 months prior to the study's initiation. Results: During the study period 70,522 Pap tests were performed in our laboratory. One third (33%) of Pap tests were screened with assistance of TIS. Manual screening was performed on 47,380 Pap tests of which 153 (0.32%) were interpreted as ASC-H and 164 (0.35%) were interpreted as HGSIL. During the same time period automated screening (TIS) was performed on 23,111 Pap tests. Interpretation of 62 (0.27%) cases provided an ASC-H result, while 71 (0.31%) were HGSIL. Follow-up cervical dysplasia by colposcopic biopsy and cone biopsy was distributed proportionally between TIS and manual screening for both ASC-H and HGSIL categories. Cervical intraepithelial neoplasia (CIN II/III) was identified on follow-up biopsy of 41% TIS cases and 45% manually screened cases for ASC-H. In the HGSIL subset 71% of TIS cases and 69% manually screened cases showed CIN II/III on follow-up. TIS was 26% less sensitive relative to manual screening for ASC-H cases and 3% less sensitive for HGSIL. Conclusion: The similar rate of detection using TIS with an equal percentage of histologic correlation for ASC-H and HGSIL lesions on follow-up histology suggests patients screened by the TIS method are being sent for appropriate follow-up surveillance and treatment. A high-grade or possible high-grade lesion is as likely to be detected by TIS as by a manual screen. The similarities in relative sensitivity and specificity in a direct comparison between manual and TIS screening methodologies indicate that TIS compared to manual screening does not affect detection in patients with high-grade cervical lesions.

The Impact

Abstract Objectives To evaluate the impact of implementing the dual interpretation of atypical squamous cells, cannot exclude high-grade squamous intraepithelial lesion (ASC-H) and low-grade squamous intraepithelial lesion (LSIL) after the Bethesda System 2014 and to compare it with other indeterminate interpretations. Methods Rates of high-risk human papillomavirus (HPV) positivity and histologic follow-up and the proportion of women with high-grade squamous intraepithelial lesion on histologic follow-up were compared for the combined interpretation of ASC-H and LSIL (ASCHL) and the categories of LSIL, cannot exclude high-grade squamous intraepithelial lesion (LSIL-H) and ASC-H. Results The percentage of ASCHL HPV-positive cases (86.0%) was similar to that of LSIL-H but significantly higher in comparison to that of ASC-H. The rates of cervical intraepithelial neoplasia grade 2 or higher (CIN 2+) and CIN 3+ for ASCHL (29.6% and 3.6%, respectively) were similar to those of LSIL-H and ASC-H. When stratified by HPV test results, the proportions of patients with CIN 2+ and CIN 3+ remained statistically similar to those with ASCHL and with LSIL-H and ASC-H. Conclusions Considering the similar risks of CIN 2+ and CIN 3+ for ASCHL and ASC-H, having a separate category of ASCHL for reporting cervical cytology appears to be redundant.

Context.— The incidence of anal cancer in the United States is on the rise in high-risk populations. The anal Papanicolaou test (APT) is advocated as a screening tool, in addition to digital rectal examination and high-resolution anoscopy. Objective.— To review our experience and the current literature to create, in cooperation with clinicians, a standardized screening and treatment algorithm given our large volume of APTs. Data Sources.— All APTs collected between January 2013 and June 2015 were reviewed and correlated with follow-up/concurrent biopsy diagnoses, and clinical and social history. In total, 1417 APTs were performed on 1185 patients and APT results were as follows: 17.4% (247 of 1417) unsatisfactory; 27.9% (395 of 1417) negative; 19.5% (276 of 1417) atypical squamous cells of undetermined significance (ASC-US); 24.1% (342 of 1417) low-grade squamous intraepithelial lesion (LSIL); 3.6% (51 of 1417) atypical squamous cells, cannot exclude high-grade squamous intraepithelial lesion (HSIL) (ASC-H); and 7.5% (106 of 1417) HSIL. In total 376 cases (26.5%) had concurrent/follow-up biopsy. Review of all unsatisfactory cases with squamous intraepithelial lesion (SIL) on biopsy showed LSIL in 19.2% (5 of 26). Anal Papanicolaou test with cytologic abnormality (ASC-US+) had an 83.8% (315 of 376) rate of biopsy-proven disease, and sensitivity was higher (92%) for high-grade anal intraepithelial neoplasia or worse (AIN2+). Overall detection of AIN2+ using ASC-US+ showed specificity of 26%, negative predictive value of 92%, and positive predictive value of 26%. Conclusions.— Anal cytology has a high abnormal rate (54.7%) and sensitivity but poor correlation with histologic grade. High unsatisfactory rate indicates need for improvement in sampling with 68.4% of cases having SIL on biopsy. Multidisciplinary effort led to improvements in sampling, cytologic interpretation, and development of a standardized management algorithm.
