Objective: The aim of this work was to evaluate 100% rapid review (100% RR) as a useful tool to detect false negative (FN) results. Study Design: A sample of 8,677 swabs was investigated; the unsatisfactory and negative results were referred to 100% RR, concordant results were taken as the final diagnosis, while the discordant results were debated in a consensus meeting to reach a conclusion. The positive results were examined by 2 cytologists. The data were entered into SAS statistical software, and the agreement of the 100% RR results with the final diagnosis was tested with the weighted kappa statistic. Results: There was a significant increase in unsatisfactory results from 348 to 1,927, and of positive results from 174 to 349. On the other hand, there was a substantial decrease in negative results from 8,155 to 6,401. Assessing the relative risk of FN results in smears that were not referred to quality control (100% RR) revealed the following results: atypical squamous cells of undetermined significance (ASC-US), 2.93; low-grade squamous intraepithelial lesion (LSIL), 2.72; high-grade squamous intraepithelial lesion/atypical squamous cells – cannot exclude HSIL (HSIL/ASC-H), 2.25. Evaluating by age group, a higher risk for LSIL (4.90) and ASC-US (3.85) was observed in patients aged under 25 years, whereas patients between 25 and 64 years and those over 64 years presented a higher risk for HSIL and ASC-H: 2.46 and 2.75, respectively. Conclusion: 100% RR is an effective screening tool for FN results in countries where molecular tests for DNA-HPV and prophylactic vaccines are not available in cervical cancer screening programs.

Objective: We aimed to evaluate the impact of implementing 100% rapid review (100% RR) as a quality control tool in cervical smear cytology. Design: A cross-sectional study was conducted in which cytology findings, false-negative results, and quality indicators were evaluated. The variables were analyzed in 2004, the year in which 100% RR was implemented, and again in 2013, i.e., 10 years on. Results: Detection of atypical squamous cells of undetermined significance (ASC-US) increased from 0.90% in 2004 to 2.47% in 2013 by routine screening. Detection of atypical squamous cells, cannot exclude a high-grade squamous intraepithelial lesion (ASC-H) increased from 13.33% in 2004 to 36.27% in 2013 by 100% RR. Detection of high-grade squamous intraepithelial lesion (HSIL) increased from 0.64% in 2004 to 4.29% in 2013 by routine screening, and increased from 0% in 2004 to 19.61% in 2013 by 100% RR. There was a significant increase (p = 0.00001) in the identification of false-negative results of ASC-US, low-grade squamous intraepithelial lesion, ASC-H, HSIL, and atypical glandular cells. All quality indicators had increased in 2013 when compared to 2004 results. Conclusions: Ten years after the implementation of the 100% RR method, improvements were found in the detection of atypia and precursor lesions and in quality indicators.

Context. Human papillomavirus (HPV) testing is widely used in cervical cancer screening in women; however, its efficiency in triaging women with atypical squamous cells of undetermined significance (ASC-US) needs to be validated. Objective. To evaluate the performance of HPV16/18 in the triage of women with ASC-US. Methods. Women presenting for routine cervical cancer screening had cervical specimens collected, with which both liquid-based cytology (LBC) and hrHPVs were examined; those with ASC-US cytology underwent colposcopy. HPV16/18 and 12 other types were tested with domestic hybridization capture and chemiluminescence signal amplification (DH3). Performance characteristics of HPV test (sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV) for identification of cervical intraepithelium neoplasma (CIN) grade 2 or worse (CIN2+), and CIN grade 3 or worse (CIN3+)) were determined using standard statistical tests. Results. 317 women with ASC-US were eligible for the study. HrHPV prevalence was 15.77% (50/317); HPV16/18 prevalence was 3.61% (20/317). Sensitivity and specificity of HPV16/18 for detection of CIN 2+ were 64.71% and 97% and 64.29% and 96.37% for detection of CIN 3+, respectively. The positive predictive values (PPVs) and negative predictive values (NPVs) of HPV16/18 were 55.00% and 97.98% for CIN2+ and 45.00% and 98.32% for CIN3+, respectively. Conclusion. HPV16/18 can be considered as an effective method to triage women with ASC-US as its good clinical performance. Trial Registration. This trial is registered with Henan Cancer Hospital Medical Ethics Committee on July 5, 2016 (http://www.anti-cancer.com.cn), with registry no.: 2016037.

Background: Pap smear examination has been universally used as an effective screening tool for early detection of cervical carcinoma. The aim of this study was to assess the utility of Cervical Acid Phosphatase staining as an adjunct to routine Pap smear testing to improvethe sensitivity and specificity of routine Pap smear examination for cervical cancer detection. Materials and Methods: Cervical smears were taken from patients attending the gynecology department and a few cervical cancer screening programmes. One set of slides were alcohol fixed and stained with rapid pap stain and another set of slides were fixed in a special fixative and stained with Cervical Acid Phosphatase -Pap stain. The nuclear features of these Cervical Acid Phosphatase stained dysplastic cells was studied on Pap stain to diagnose cervical intraepithelial lesion/ malignancy. Results: Out of 489 cases included in the study 6 cases were diagnosed with intraepithelial lesion/ malignancy. On Cervical Acid Phosphatase -Pap stain 2 of the cases diagnosed as inflammatory smears on pap stain showed Cervical Acid Phosphatase positivity and thus were re evaluated. Mild nuclear atypia was observed in the Cervical Acid Phosphatase positive cells and these cases were diagnosed as Low grade squamous intraepithelial lesion and later biopsy proven to be Cervical intraepithelial Neoplasia I. Therefore Cervical Acid Phosphatase -Pap test was 100% sensitive and specific for cervical cancer detection. Conclusions: With 100% sensitivity Cervical Acid Phosphatase -Pap test satisfies the criteria of an efficient screening test.

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.

Abstract Background Cervical cancer is a leading cause of death in low- and middle-income countries. Self-collection testing for human papillomavirus (HPV) is an alternative form of cervical cancer screening that can be completed privately and at home. Understanding how the use of HPV testing influences follow-up care in low-resourced settings is crucial before broad implementation. This study aimed to identify if access to self-collection HPV testing impacts participation in established cervical cancer screening programs among women in two rural communities in Guatemala. Methods A cohort of 956 women was recruited in 2016 and followed for 2 years for the HPV Multiethnic Study (HPV MES). At baseline, women answered a questionnaire assessing cervical cancer screening history and were offered self-collection HPV testing. Women were re-contacted yearly to determine receipt of additional screening. Statistical changes in screening behavior before and throughout study participation, stratified by self-collection status, were assessed using McNemar pair tests for proportions. Alluvial plots were constructed to depict changes in individual screening behavior. The odds of changes in Pap-compliance (screened in past 3 years), given collection status, were assessed using multivariate logistic regressions. Results Reported screening rates increased 2 years after enrollment compared to rates reported for the 3 years before study entry among women who collected a sample (19.1% increase, p < 0.05), received results of their test (22.1% increase, p < 0.05), and received positive (24.2% increase, p < 0.1) or negative results (21.7% increase, p < 0.05). However, most increases came from one community, with minimal changes in the other. The adjusted odds of becoming Pap compliant were higher for women who collected a sample vs. did not (OR: 1.48, 95% CI: 0.64, 3.40), received their result vs. did not (OR: 1.29, 95% CI: 0.52, 3.02), and received a positive result vs. negative (OR: 2.43, 95% CI: 0.63, 16.10). Conclusions Participation in self-collection HPV testing campaigns may increase likelihood of involvement in screening programs. However, results varied between communities, and reporting of screening histories was inconsistent. Future work should identify what community-specific factors promote success in HPV testing programs and focus on improving education on existing cervical cancer interventions.
