Abstract
To compare all available accuracy data on screening strategies for identifying cervical intraepithelial neoplasia grade ≥ 2 in healthy asymptomatic women, we performed a systematic review and network meta-analysis. MEDLINE and EMBASE were searched up to October 2020 for paired-design studies of cytology and testing for high-risk genotypes of human papillomavirus (hrHPV). The methods used included a duplicate assessment of eligibility, double extraction of quantitative data, validity assessment, random-effects network meta-analysis of test accuracy, and GRADE rating. Twenty-seven prospective studies (185,269 subjects) were included. The combination of cytology (atypical squamous cells of undetermined significance or higher grades) and hrHPV testing (excepting genotyping for HPV 16 or 18 [HPV16/18]) with the either-positive criterion (OR rule) was the most sensitive/least specific, whereas the same combination with the both-positive criterion (AND rule) was the most specific/least sensitive. Compared with standalone cytology, non-HPV16/18 hrHPV assays were more sensitive/less specific. Two algorithms proposed for primary cytological testing or primary hrHPV testing were ranked in the middle as more sensitive/less specific than standalone cytology and the AND rule combinations but more specific/less sensitive than standalone hrHPV testing and the OR rule combination. Further research is needed to assess these results in population-relevant outcomes at the program level.

Abstract
INTRODUCTION Papanicolaou test quality metrics include the ASC rate, ASC:SIL ratio, and ASC HPV+ rate. What a laboratory should do when metrics show a worrisome trend is not well defined. In 2015, our laboratory noted a worrisome trend in our quality metrics and decided to implement a systemic education program in 2016; we monitored the effectiveness of our program. METHODS An educational intervention was designed for March/April 2016. Cytotechnologist education consisted of: group meeting on March 10 to discuss metrics, lecture, and written materials on ASC-US criteria, a quiz on challenging ASC-US cases, encouragement to seek consultation, and each cytotechnologist received quarterly individual metrics. The cytopathologist education consisted of: group meeting on April 16 to discuss metrics, encouragement to bring borderline cases to consensus conference, and each faculty received quarterly individual metrics. The ASC rate, ASC:SIL ratio, and ASC HPV+ rate was collected for the institution and each individual faculty in 2016 for January to March (pre-interventions, Q1), April to June (post-interventions, Q2), and July to September (post-interventions, Q3). ASC-H was included in the calculation of ASC %, ASC:SIL, and ASC HPV+ rates. RESULTS There was a substantial decline in the lab ASC rate and ASC:SIL ratio, and the ASC HPV+ rate increased. Individual faculty changes in ASC:SIL ratio and ASC HPV+ rate also improved. CONCLUSIONS In our institution, an educational program has been very effective in improving Papanicolaou test metrics. It is helpful to perform re-education at all levels within the department.

Abstract
BACKGROUND To investigate whether routine cervical screening using human papillomavirus (HPV) and cytology co-testing effectively identifies women with endometrial (EC) or ovarian (OvC) cancer. METHODS In 2003, Kaiser Permanente Northern California implemented triennial co-testing in women aged ≥30 years. Index screening results (n = 2,385,729) were linked to subsequent EC (n = 3434) and OvC (n = 1113) diagnoses from January 1, 2003 to December 31, 2017. EC were categorized as type 1 or 2, and, selectively, EC and OvC diagnoses were stratified on whether symptoms were present at the time of the co-test. Fractions and absolute risks of EC or OvC of each co-testing result were calculated. RESULTS Most EC (82.18%) and OvC (88.68%) were preceded by a negative HPV and negative cytology co-test. More EC were preceded by atypical squamous cells of undetermined significance (ASC-US) or more severe (ASC-US+) cytology and negative HPV test (n = 290) (8.44% of EC) compared to a negative cytology and a positive HPV test (n = 31) (0.89% of EC) (p < 0.001). The absolute risk of any EC diagnosis following ASC-US+ and negative HPV test was 0.48%. Atypical glandular cells (AGC) cytology and a negative HPV result preceded 6.92% of any EC diagnosis, with an absolute risk of 4.02%, but preceded only 1.13% of type 2 EC cases, with an absolute risk of 0.24%, in asymptomatic women. AGC cytology and a negative HPV result preceded 1.44% of OvC, with an absolute risk of 0.28%. CONCLUSIONS Abnormal cervical screening tests, even AGC cytology, rarely precedes and poorly predict women with EC or OvC.

Abstract
The S5-methylation test, an alternative to cytology and HPV16/18 genotyping to triage high-risk HPV-positive (hrHPV+) women, has not been widely validated in low-middle-income countries (LMICs). We compared S5 to HPV16/18 and cytology to detect cervical intraepithelial neoplasia Grade 2 or worse (CIN2+) and CIN3+ in hrHPV+ women selected from a randomized pragmatic trial of 2661 Colombian women with an earlier-borderline abnormal cytology. We included all hrHPV+ CIN2 and CIN3+ cases (n = 183) age matched to 183

Abstract
OBJECTIVE Cervical cytology and Human papillomavirus (HPV) testing are effective screening techniques but both have limitations. A few recent studies in the literature have highlighted the role of co-expression of p16INK4a and Ki-67 for cervical cancer screening. The present study was undertaken to evaluate the diagnostic performance of the CINtec® PLUS kit (dual immunostaining for p16 and Ki-67) in SurePathTM liquid-based (LBC) cervico-vaginal samples. MATERIALS AND METHODS This was a prospective study performed on 52 cervico-vaginal SurePath™ LBC samples reported as having squamous epithelial cell abnormality (ECA). All the samples were stained using CINtec® PLUS kits. Additionally, HPV-DNA testing was also done and the results were compared. RESULTS The age range was 34-74 years. ECA included 18 (34.6%) cases of ASC-US, 9 (17.3%) cases of low-grade squamous intraepithelial lesion (LSIL), 11 (21.2%) cases of high-grade squamous intraepithelial lesion (HSIL), and 14 (26.9%) cases of squamous cell carcinoma (SCC). Cervical biopsies were available in 19 (36.5%) cases. A total of 34/52 (65.4%) cases were positive for HPV-DNA (5/18-ASC-US; 6/9-LSIL; 10/11-HSIL; 13/14-SCC). The CINtec® PLUS test was positive in 41/52 (78.8%) cases (11/18-ASC-US; 6/9-LSIL; 11/11-HSIL; 13/14-SCC). On comparing CINtec® PLUS positivity (78.8%) with HPV positivity (65.4%), dual positivity was seen in 3/18 cases of ASC-US, 6/9 cases of LSIL, 10/11 cases of HSIL, and 12/14 cases of SCC. One case each of HSIL and SCC was negative on the HPV test and was positive on CINtec® PLUS. CONCLUSIONS CINtec® PLUS test helps to improve the detection of pre-cancerous cervical lesions as compared to cervical cytology or HPV testing alone and hence can serve as a potentially useful diagnostic and triage tool, especially for indeterminate cases.

Abstract
INTRODUCTION High-risk human papillomavirus (HR HPV) is found to be responsible for 4.5% of cancer in general, primarily cervical cancer. We aim here to highlight the prevalence and genotypes of HR HPV and correlate its association with Pap tests' results, which are still not well known in the Eastern Province of Saudi Arabia. METHODS Over 7 years (2013-2019), the results of 164 Saudi women coinvestigated for HR HPV along with Pap tests were collected from the archive of King Fahd University Hospital. Only women who had atypical squamous cells of undetermined significance (ASCUS) on the Pap test and those at elevated risk of infection were cotested for HR HPV; otherwise, the Pap test was the only screening modality for cervical cancer. Data were organized and statistically analyzed using IBM SPSS v26. RESULTS Out of 164 Saudi women, 14.5% (n = 24/164) showed positive results for HR HPV (8 patients had HPV16 and 2 had both HPV16 and HPV18/45, while the remaining 14 had other HR HPV); among them, 41.5% (n = 10/24) had an abnormal Pap test (5 ASCUS and 5 LSIL), while 58.5% (n = 14/24) had a negative Pap test. On the other hand, 21% (n = 35/164) of patients, in the study, had an abnormal Pap test (24 ASCUS, 8 low-grade squamous intraepithelial lesion [LSIL], and 3 atypical glandular cell [AGC]). In 80% (n = 19/24) of ASCUS cases, HR HPV was not detected; however, 20% (n = 5/24) were positive for other HR HPV. Concerning LSIL cases, 62.5% (n = 5/8) were positive for HR HPV (1 case showed HPV16 and HPV18/45, 2 cases showed HPV16, and 2 cases showed other HR HPV), while in the remaining 37.5% (n = 3/8) LSIL cases, HR HPV was negative; similarly, all AGC cases were negative for HR HPV. Statistical analysis showed a significant correlation between HPV status and Pap test findings (p value <0.001). DISCUSSION/CONCLUSION HR HPV frequency and genotype distribution, in this study, might reflect a different regional infection pattern. The high association of HR HPV with negative cytology emphasizes the need to add the HR HPV test to screening modalities of cervix cancer.

Abstract
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.

Abstract
OBJECTIVE New rapid and low-cost molecular tests for cervical cancer screening, such as the OncoE6 Cervical Test, are emerging and could be alternatives for low-income and middle-income countries. To this end, we evaluated the clinical performance of the OncoE6 Cervical Test in detecting cervical intraepithelial neoplasia (CIN) among HIV-infected women in Bujumbura, Burundi. METHODS From June to December 2017, a cross-sectional study was conducted in 680 HIV-positive women at the University Hospital. Women aged 25-65 years who declared having had vaginal intercourse were consecutively recruited, and cervical specimens for OncoE6, liquid-based cytology and human papillomavirus (HPV) genotyping were obtained and visual inspection with acetic acid performed. Thereafter, participants underwent a colposcopic examination. The sensitivity, specificity, and positive and negative predictive values of the different tests were calculated with reference to 'colposcopic-histological' diagnoses, and areas under the receiver operating curves of OncoE6 and cytology tests were compared. RESULTS The prevalence of CIN was 4.9%, and OncoE6 positivity was 3.1%. OncoE6 sensitivity varied from poor to low with increasing disease severity (42.1%, 95% CI 19.9% to 64.3% at CIN2+ threshold; and 58.3%, 95% CI 30.4% to 86.2% at CIN3+ threshold). OncoE6 had the highest specificity compared with all other tests used together. The performance of the OncoE6 test was significantly lower compared with cytology at atypical squamous cell of undetermined significance (ASCUS+) cut-off (AUC=0.68 vs 0.85, p=0.03) and low-grade squamous intraepithelial lesion (LSIL+) cut-off (AUC=0.68 vs 0.83, p=0.04) for CIN2+ diagnoses. However, the performance of the OncoE6 test was similar to that of cytology at high-grade squamous intraepithelial lesion (HSIL+) cut-off (AUC=0.68 vs 0.76; p=0.30) for CIN2+ diagnoses and was also similar to that of cytology at all cut-offs (ASCUS+, LSIL+ and HSIL+) for CIN3+ diagnoses (p1=0.76, p2=0.95 and p3=0.50, respectively). CONCLUSION The current OncoE6 test proved to be a point-of-care test. However, given its poor performance for CIN2+ diagnoses, we do not recommend it for primary screening. We recommend to enrich it with more oncogenic HPV types, which may improve the performance of the test akin to that of cytology.

INTRODUCTION A causal link between infection with a high-risk strain of human papilloma virus (hrHPV) and the development of cervical squamous cell carcinoma (SCC) is well established. However, a small number of SCCs are hrHPV-negative by either HPV co-DNA testing and/or HPV-in situ hybridization (HPV-ISH) at the time of diagnosis. These apparently hrHPV-negative lesions are poorly understood, specifically whether hrHPV-positive precursor lesions exist, which would be detected through hrHPV-based screening. METHODS A search of the pathology archives at the Johns Hopkins Hospital identified women with a diagnosis of hrHPV-negative cervical SCC on surgical specimen. All prior pathologies, including cervical cytology and surgical pathology specimens, and associated hrHPV DNA test results, p16 immunohistochemistry, and HPV-ISH were reviewed. RESULTS A total of 25 women were identified having a surgical specimen diagnosed as SCC with either negative or equivocal HPV-ISH. Fifteen had a Pap test in the 6 months preceding a diagnosis of SCC, with cytology diagnoses as follows: high-grade squamous intraepithelial lesion n = 14/15; atypical squamous cells, cannot exclude high-grade squamous intraepithelial lesion n = 1/15. hrHPV co-testing was performed for 5 of these 15 women and was negative in 2/5 cases. Cervical biopsy was performed for 24 women. HPV-ISH testing, performed on 14 of the biopsy specimens, was negative for 11/14 patients. Of 15 specimens stained for p16, 14 were positive. CONCLUSION A subset of patients exist in whom hrHPV is not detectable at or near the time of progression to SCC. Additional research is necessary to further describe this population and determine whether maintaining cytological screening would provide benefit.

Abstract
BACKGROUND Women with atypical squamous cells of undetermined significance (ASC-US) can be triaged accurately with a high-risk human papillomavirus (hrHPV) test to identify those who need a referral. However, the triage of low-grade squamous intraepithelial lesion (LSIL) with hrHPV testing has very low specificity. Overexpression of p16, with or without Ki-67, indicates neoplastic transformation of human papillomavirus-infected cervical cells and may more accurately predict underlying cervical intraepithelial neoplasia of grade 3 or worse (CIN3+). METHODS A literature search was conducted in 3 bibliographic databases. Studies were selected if they included women with ASC-US or LSIL who were triaged with dual staining (p16/Ki-67) and/or p16 staining and, if available, with a comparator hrHPV test to detect cervical intraepithelial neoplasia of grade 2 or worse (CIN2+) or CIN3+. RESULTS Thirty-eight studies were eligible. The sensitivity of p16 staining for CIN3+ was significantly lower than that of hrHPV DNA testing (ratio for ASC-US, 0.87; 95% confidence interval [CI], 0.78-0.97; ratio for LSIL, 0.86; 95% CI, 0.80-0.93). In contrast, the specificity of p16 staining was substantially higher with relative specificities of 1.60 (95% CI, 1.35-1.88) and 2.29 (95% CI, 2.05-2.56) for ASC-US and LSIL respectively. Dual staining was as sensitive as hrHPV DNA testing but was more specific (ratio for ASC-US, 1.65; 95% CI, 1.42-1.92; ratio for LSIL, 2.45; 95% CI, 2.17-2.77). CONCLUSIONS This meta-analysis confirms that p16 staining and p16/Ki-67 staining are more specific for CIN2+/CIN3+ than hrHPV DNA testing. Although p16 staining is less sensitive for CIN3+ than hrHPV DNA testing, dual staining has similar sensitivity.

Abstract
OBJECTIVES The aim of this work was to study the spectrum of epithelial abnormalities on Pap smears of HIV-positive women categorized as per the Bethesda System of Reporting Cervical Cytology, to correlate them with CD4 lymphocyte counts, and to compare them with the spectrum of abnormalities seen in a HIV-negative control group. Study Design and Methodology: The present study was a 6-year retrospective study conducted in the Department of Pathology at Kasturba Medical College, Mangalore, which included 150 Pap smears from HIV-positive and HIV-negative women, respectively. The Pap-stained slides of the cases were retrieved and studied. The data collected were tabulated and analyzed. A statistical study was performed using SPSS software. The χ2 test was used to analyze the data and a p value < 0.05 was considered to be significant. RESULTS Pap smear abnormalities were twice as high in HIV-infected women (12%) as compared with HIV-negative women (6%; p = 0.006, RR = 2). Negative for intraepithelial lesion/malignancy was the most common finding (88%), which was further subdivided into inflammatory, atrophic smear, non-specific, candidiasis, and bacterial vaginitis groups. The percentage of epithelial abnormalities was 12%, including: atypical squamous cells of undetermined significance, 5.55%; atypical squamous cells, cannot exclude HSIL, 16.66%; low-grade squamous intraepithelial lesion, 5.55%; high-grade squamous intraepithelial lesion (HSIL), 61.11%, and squamous cell carcinoma, 11.11%. The highest incidence of intraepithelial lesions in HIV-positive females was in the age group of 34-49 years. CD4 cell counts fell in the range of 200-500 cells/mm3 in most of the HIV-positive patients (68.75%), but was not found to be statistically significant. CONCLUSION Routine Pap smear examination is advocated in women with HIV as the prevalence of epithelial cell abnormalities was found to be 12%, which was twice as high as compared to the HIV-negative control group. Although there was no correlation of epithelial cell abnormalities with CD4 counts, a higher rate of the cases with epithelial abnormalities were observed to have CD4 cell counts of 200-500 cells/mm3.

Abstract
OBJECTIVE Atypical Squamous Cells of Undetermined Significance(ASCUS) is the most reported result on pap smears. It is most commonly related to Human Papillomavirus (HPV) infections. However, other pathogens (EBV, Chlamydia) have been reported on cervical samples with abnormal results. Zika virus(ZIKV) has been found to induce cellular abnormalities on different tissues and its presence has been identified on genital secretions. METHODS Two real-time PCR has been made on cervical samples from the gynecological service of a third level hospital on Guayaquil-Ecuador. This work was part of a bigger study of ZIKV presence on different body fluids. RESULTS From 89 samples obtained, 19 received an ASCUS result. From these 5 were positive for ZIKV and 5 were positive for HPV, there were no co infections. CONCLUSION Given the presence of ZIKV RNA and the absence of HPV DNA on cervical samples diagnosed as ASCUS, it might be plausible that ZIKV could be a triggering factor for the induction of cellular changes observed on these cells.

Abstract
4vHPV vaccination has been tested in randomized controlled trials under almost ideal conditions, and studies of real-life use have compared outcome between vaccinated and unvaccinated women from the same birth cohort and mostly before screening age. Here we present the first-to our knowledge-evaluation of the impact of the 4vHPV vaccination in real life without selection bias in the reported data. The study has been carried out by comparing the results after first cervical screening between an HPV-vaccinated and an unvaccinated birth cohort, consisting of women born in Denmark in 1993 and 1983, respectively. Cytology data covering an 8-year period, from the age of 15 (age of HPV-vaccination) to age 23 (age of invitation to first cervical screening), were retrieved from the Danish National Pathology Register. Abnormal cytology, defined as atypical squamous cell of undetermined significance and worse (ASCUS+) was detected in 9.4% of women born in 1993 as compared with 9.0% of women born in 1983; RR = 1.04 (95% CI 0.96-1.12), p = .29. Detection of high-grade squamous intraepithelial lesion (HSIL) was statistically significantly lower in the 1993 than in the 1983 cohort, RR = 0.6 (95% CI 0.5-0.7), p < .0001, while the opposite pattern was seen for ASCUS RR = 1.4 (95% CI 1.2-1.6), p < .0001. The decrease in HSIL means that more women can be spared referral for colposcopy and biopsy. The increase of ASCUS could be explained by transition from conventional to liquid-based cytology, but this observation requires further monitoring.

Abstract
Objective To investigate the diagnostic value of human papillomavirus (HPV) E6/E7 mRNA combined with P16/antigen KI-67(ki67) immunocytochemical double staining in the atypical squamous cells of undetermined significance (ASCUS). Methods A total of 272 patients were selected and the results of HPV E6/E7 and P16/ki67 immunocytochemical double staining in the remaining cytological specimens were retrospectively analyzed. HPV E6/E7 gene was detected by HPV E6/E7 gene detection kit and Panther molecular diagnostic instrument. P16/ki67 was detected by immunocytochemical staining and Ventana Benchmark Ultra immunohistochemical staining instrument. Then we analyzed the difference of positive rate between the two detection methods in the same grade of cervical epithelial lesions, explored the difference of the two detection methods and their combined detection in the diagnosis of high grade squamous intraepithelial lesions (HSIL), and finally evaluated the role of different detection methods in shunt diagnosis of ASCUS. Results Histopathological findings of cervical cytology ASCUS includes chronic cervicitis, low-grade squamous intraepithelial lesions (LSIL), HSIL and cervical cancer. The positive rate of simple molecular diagnosis or immunocytochemical staining increased with the severity of cervical lesions. In cervicitis and LSIL lesion group, the difference between the positive rates of the two methods was obvious, but in HSIL and cervical cancer lesion group, there was no significant difference between the positive rates of the two methods. The sensitivity, specificity, Yoden index, coincidence rate, positive predictive value and negative predictive value were 95.65%, 85.40%, 0.81, 87.13%, 57.14% and 98.97%, respectively. Conclusion The detection of HPV E6/E7 and P16/ki67 immunocytochemical staining has certain significance in ASCUS shunt diagnosis. The combined detection of HPV E6/E7 and P16/ki67 can significantly improve the sensitivity of shunt diagnosis and maintain a good specificity.

Abstract
OBJECTIVES The aim of this study was to evaluate the diagnostic significance of high-risk human papillomavirus (hrHPV) testing for managing women with atypical glandular cells (AGC) and to explore the distribution of hrHPV genotypes. METHODS We analyzed cytologic and histopathologic diagnoses in patients referred to our institution due to AGC or atypical squamous cells of undetermined significance (ASC-US). All patients underwent hrHPV testing and genotyping, and positive (PPV) and negative predictive values (NPV) for cervical intraepithelial neoplasia (CIN) 2 or worse [CIN2+/adenocarcinoma in situ (AIS)+] were calculated. RESULTS Among 41 cases previously diagnosed with AGC, 22 (53%) were classified as CIN2+ (2 squamous cell carcinomas), whereas only 2 were AIS or adenocarcinoma. Twenty-seven (65.8%) cases in the AGC group were hrHPV positive. The most frequent genotypes in both the ASC-US and AGC groups were HPV16 and HPV52. The PPV of hrHPV testing for CIN2+/AIS+ was significantly higher in the AGC than in the ASC-US group (74.1 vs. 35.0%; p = 0.0005). The NPV for CIN2+/AIS+ was significantly lower in the AGC than in the ASC-US group (74.4 vs. 100%; p = 0.0441). CONCLUSION In patients with AGC, both glandular and squamous lesions must be monitored. hrHPV testing is useful for detecting CIN2+/AIS+ in AGC.

Abstract
OBJECTIVE We aimed to assess potential associations between atypical squamous cell (ASC) subgroups: ASC-US (undetermined significance) and ASC-H (cannot exclude high-grade squamous intraepithelial lesion), regarding cytomorphological features, high-risk (HR) human papillomavirus (HPV) testing, and histological outcomes in a sample of Brazilian women. STUDY DESIGN Cross-sectional study which evaluated 1,346 liquid-based cytologies between January 2010 and July 2016 with ASC results. ASC-US and ASC-H were analyzed for frequency, diagnostic criteria, and cytological findings and compared with HR-HPV tests and histological outcomes. RESULTS Enlarged nucleus was the most frequent ASC-US criterion, but alternative criteria were present in 20% of the total cases. No ASC-US criteria were associated with histological outcomes or HR-HPV positivity. Parakeratosis, corneal pearl, giant cells, and binucleation were strongly associated with ASC-US while hyperkeratosis was associated with high-grade squamous intraepithelial lesions (HSIL) or a superior outcome. HR-HPV was positive in 64.39% of ASC-US and 65.38% of ASC-H. HSIL or superior outcomes also occurred in 13.33% of ASC-US and 64.71% of ASC-H cases. CONCLUSION Alternative criteria for ASC-US were relatively frequent. Reactive cellular changes suggestive of atypias were more abundant in ASC-US. Although ASC-H is associated with worse histological outcomes, no differences in HPV positivity were found in comparison to ASC-US.

Abstract
Introduction Primary-prevention by prophylactic vaccination against HPV-related cancers and HPV-based screening programs are based on HPV-type distribution in immunocompetent individuals. HIV-infected women are at high risk of invasive HPV-disease sustained by a broader range of HPV-types and have higher multi-type infection rates than immunocompetent hosts. Methods This is a cross-sectional analysis of High Risk HPV (HR HPV) type distribution in 805 HIV+ women (HIW) compared with a control group of 1402 immunocompetent HIV- women (SPW) enrolled in the VALHIDATE study in order to define HPV type-specific distribution according to cytology. Results HIW had a 3.8, 3.6, and 2.7 times higher risk of atypical squamous cells of undetermined significance (ASCUS), low-grade squamous intraepithelial lesion (LSIL) and high grade squamous intraepithelial lesion (HSIL) than SPW respectively. HPV-DNA prevalence was 28.4% in HIW and 11.81% in SPW (p<0.0001). The prevalence of infection increased from normal cytology to HSIL both in HIW (from 21.45% to 90.91%) and SPW (from 9.54% to 75%). The OR for women with normal cytology of having a positive HPV-DNA test result of was 2.6 times higher in HIW than in SPW. The cumulative prevalence of HPV-16/18 in HSIL is much lower in HIW (36.4±28.4) than SPW (62.5±33.5). Conclusions A higher prevalence of infection and broader HPV type distribution were observed in HIV+ women compared to the general population. More than 60% of HSIL lesions of HIW patients are caused by single or multi-type infections from non-HPV16/18 HPVs. The potential 9v-HPV vaccine coverage could be even higher than that expected for the general population given the wide panel of HPV-types observed in the HSIL of HIV+ women.

Abstract
BACKGROUND This study was performed to evaluate the surface plasmon resonance-based (SPR) test with the W2600 System of GP Medical Technologies as a screening method for human papillomavirus (HPV) genotyping in China. METHODS Between November 2012 and December 2013, the SPR test, hybrid capture II (HC2) test, and direct DNA sequencing assay were performed on 424 patients aged 22 - 65 years who attended the outpatient clinic at the Department of Obstetrics and Gynecology of West China Second University Hospital with diagnoses of chronic cervicitis or abnormal vaginal bleeding. Cervical specimens were collected from the cervical epithelia. Cytological and histological studies were also performed. RESULTS A total of 424 patient specimens were screened. The positive, negative, and overall concordance between the SPR test and HC2 test was 93.48%, 89.16%, and 90.57%, respectively. The concordance between the SPR test and the direct DNA sequencing assay was 97.41%. Against the results of the direct DNA sequencing assay, the SPR test demonstrated a sensitivity of 96.86% and a specificity of 97.74%. CONCLUSIONS The SPR test is reliable, sensitive, and specific for HPV genotyping. Compared to the hybrid-capture assay, the SPR test may work on more than one specimen at a time and is a low-cost, rapid, and easy-to-use method with the potential for automation. The SPR test may be widely employed in China and other countries for HPV genotyping.

Abstract
OBJECTIVE The aim of this study was to assess the correlation between atypical squamous cells (ASC) and inflammatory infiltrate and vaginal microbiota using cervical liquid-based cytological (SurePath®) and high-risk human papillomavirus (HR-HPV) tests. STUDY DESIGN A cross-sectional study was conducted using a 6-year database from a laboratory in Fortaleza (Brazil). Files from 1,346 ASC cases were divided into subgroups and results concerning inflammation and vaginal microorganisms diagnosed by cytology were compared with HR-HPV test results. RESULTS An absence of specific microorganisms (ASM) was the most frequent finding (ASC of undetermined significance, ASC-US = 74%; ASC - cannot exclude high-grade squamous intraepithelial lesion, ASC-H = 68%), followed by bacterial vaginosis (ASC-US = 20%; ASC- H = 25%) and Candida spp. (ASC-US = 6%; ASC-H = 5%). Leukocyte infiltrate was present in 71% of ASC-US and 85% of ASC-H (p = 0.0040), and in these specific cases HR-HPV tests were positive for 65 and 64%, respectively. A positive HR-HPV test was relatively more frequent when a specific microorganism was present, and Candida spp. was associated with HR-HPV-positive results (p = 0.0156), while an ASM was associated with negative HR-HPV results (p = 0.0370). CONCLUSION ASC-US is associated with an absence of inflammation or vaginosis, while ASC-H smears are associated with Trichomonas vaginalis and inflammatory infiltrate. A positive HR-HPV is associated with Candida spp. in ASC cytology.

Abstract
OBJECTIVES Determine performance of the cobas human papillomavirus (HPV) test for triage of atypical squamous cells of undetermined significance (ASC-US) in SurePath. METHODS Women presenting for routine screening had cervical specimens collected in SurePath and specimen transport medium (STM); those with ASC-US cytology underwent colposcopy. Performance of cobas HPV in SurePath specimens that had undergone a preanalytic procedure to reverse possible cross-linking of HPV DNA was compared with Hybrid Capture 2 (hc2) specimens in STM. RESULTS Among 856 women, HPV prevalence was 45.8%; HPV 16 and HPV 18 prevalences were lower than expected in the 21- to 29-year-old group in this highly vaccinated population. cobas HPV performance in SurePath was comparable to hc2 in STM. Sensitivity and specificity for detection of cervical intraepithelial neoplasia grade 3 or worse were 87.5% (95% confidence interval [CI], 71.9%-95.2%) and 55.5% (95% CI, 52.1%-58.9%) for cobas and 85.3% (95% CI, 69.9%-93.6%) and 54.7% (95% CI, 51.4%-57.9%) for hc2. Sensitivity was negatively affected by random biopsies performed at colposcopy; comparable sensitivities were achieved in the nonvaccinated and vaccinated populations with disease determined by directed biopsy only. CONCLUSIONS Performance of cobas HPV for ASC-US triage in pretreated SurePath specimens meets criteria for validation. Preliminary data indicate reliable performance of HPV testing in a highly vaccinated population.

Abstract
BACKGROUND Using primary human papillomavirus (HPV) testing for cervical screening increases detection of high-grade cervical intraepithelial neoplastic lesions and invasive cancer (cervical intraepithelial neoplasia grade 2+ [CIN2+]) compared to cytology, but no evaluation has been conducted in a population previously offered HPV vaccination. We aimed to assess colposcopy referral and CIN2+ detection rates for HPV-screened versus cytology-screened women in Australia's HPV-vaccinated population (by 2014, resident women ≤33 years had been age-eligible for HPV vaccination, with 3-dose uptake across age cohorts being about 50%-77%). METHODS AND FINDINGS Compass is an open-label randomised trial of 5-yearly HPV screening versus 2.5-yearly liquid-based cytology (LBC) screening. In the first phase, consenting women aged 25-64 years presenting for routine screening at 47 primary practices in Victoria, Australia, provided a cervical sample and were randomised at a central laboratory at a 1:2:2 allocation to (i) image-read LBC screening with HPV triage of low-grade cytology ('LBC screening'), (ii) HPV screening with those HPV16/18 positive referred to colposcopy and with LBC triage for other oncogenic (OHR) types ('HPV+LBC triage'), or (iii) HPV screening with those HPV16/18 positive referred to colposcopy and with dual-stained cytology triage for OHR types ('HPV+DS triage'). A total of 5,006 eligible women were recruited from 29 October 2013 to 7 November 2014 (recruitment rate 58%); of these, 22% were in the group age-eligible for vaccination. Data on 4,995 participants were analysed after 11 withdrawals; 998 were assigned to, and 995 analysed (99.7%) in, the LBC-screened group; 1,996 assigned to and 1,992 analysed (99.8%) in the HPV+LBC triage group; and 2,012 assigned to and 2,008 analysed (99.8%) in the HPV+DS triage group. No serious trial-related adverse events were reported. The main outcomes were colposcopy referral and detected CIN2+ rates at baseline screening, assessed on an intention-to-treat basis after follow-up of the subgroup of triage-negative women in each arm referred to 12 months of surveillance, and after a further 6 months of follow-up for histological outcomes (dataset closed 31 August 2016). Analysis was adjusted for whether women had been age-eligible for HPV vaccination or not. For the LBC-screened group, the overall referral and detected CIN2+ rates were 27/995 (2.7% [95% CI 1.8%-3.9%]) and 1/995 (0.1% [95% CI 0.0%-0.6%]), respectively; for HPV+LBC triage, these were 75/1,992 (3.8% [95% CI 3.0%-4.7%]) and 20/1,992 (1.0% [95% CI 0.6%-1.5%]); and for HPV+DS triage, these were 79/2,008 (3.9% [95% CI 3.1%-4.9%]) and 24/2,008 (1.2% [95% CI 0.8%-1.6%]) (p = 0.09 for difference in referral rate in LBC versus all HPV-screened women; p = 0.003 for difference in CIN2+ detection rate in LBC versus all HPV-screened women, with p = 0.62 between HPV screening groups). Limitations include that the study population involved a relatively low risk group in a previously well-screened and treated population, that individual women's vaccination status was unknown, and that long-term follow-up data on disease detection in screen-negative women are not yet available. CONCLUSIONS In this study, primary HPV screening was associated with significantly increased detection of high-grade precancerous cervical lesions compared to cytology, in a population where high vaccine uptake was reported in women aged 33 years or younger who were offered vaccination. It had been predicted that increased disease detection might be associated with a transient increase in colposcopy referral rates in the first round of HPV screening, possibly dampened by HPV vaccine effect; in this study, although the point estimates for referral rates in women in each HPV-screened group were 41%-44% higher than in cytology-screened women, the difference in referral rate between cytology- and HPV-screened women was not significant. These findings provide initial support for the implementation of primary HPV screening in vaccinated populations.

Abstract
OBJECTIVES To investigate the accuracy of colposcopy for diagnosing high-grade squamous intraepithelial lesion (HSIL) or worse (HSIL+) in human papillomavirus (HPV)-infected patients with atypical squamous cells of undetermined significance (ASCUS) cytology, and determine whether genotyping and viral load quantitation can be useful for detecting immediate HSIL+ risk in these patients. STUDY DESIGN This study included 620 cases with ASCUS and positive for high-risk (HR)-HPV within 1 month before or after cervical cytology at Qilu Hospital between February 2013 and February 2014. Based on the colposcopic impression, lesion-targeted punch biopsy, endocervical curettage biopsy or random cervical punch biopsy in four quadrants was performed on these patients within 1 month. The accuracy of colposcopy for diagnosing HSIL+ was evaluated through comparison with the biopsy results. HR-HPV status determined by Hybrid Capture 2 or HPV genotyping was analysed retrospectively as a possible predictor of HSIL+. RESULTS Agreement between colposcopic impression and cervical pathology was matched perfectly in 89.2% of cases (553/620), and the strength of agreement with the κ statistic was 0.698 (p<0.001). Colposcopy had high specificity (96.9%) but low sensitivity for detecting HSIL+ (67.5%). The risk of HSIL+ was significantly higher in patients with HPV-16 infection (52.3%) than in patients infected with other types of HPV (17.9%, p<0.001). HSIL+ and virus load was correlated at cut-offs (CO) of 50 relative light units (RLU)/CO and 100 RLU/CO (p=0.024 and 0.044, respectively). If considering HPV16 infection or high virus load (at 50 RLU/CO) as a diagnostic standard of HSIL+ when colposcopic impression was negative, sensitivity was improved to 74.7% and 81.0%, respectively. CONCLUSIONS Good agreement was found between colposcopic and pathologic diagnosis. HR-HPV genotyping or virus load is relevant to the detection of HSIL+ among HPV-infected patients with ASCUS cytology. In these patients, biopsies considering HPV-16 infection or virus load ≥50 RLU/CO may be helpful for increasing the HSIL+ detection rate.

Abstract
BACKGROUND Women positive to human papillomavirus (HPV+) testing at cervical screening need triage, typically cytology and immediate colposcopy in case of atypical squamous cells of undetermined significance (ASCUS) or worse (ASCUS+) or, in cytology-normal HPV+ women, HPV test repeat after 1 year and colposcopy referral if still HPV+. Our hypothesis was that substantial variations in triage positivity and sensitivity may produce little variation in overall referral to colposcopy and on sensitivity of the entire screening process. METHODS Centre- and age-aggregated data from 72,869 women aged 35-64 years were derived from 10 organised screening programmes which have piloted HPV screening in Italy since 2012. Overall colposcopy referral was evaluated as a function of immediate colposcopy referral and overall CIN2+ detection as a function of the proportion of all CIN2+ detected by immediate referral (a proxy of cytology's sensitivity). We fitted additive regression models, adjusted for centre, age, compliance to HPV retesting and to colposcopy, by generalised estimation equations. RESULTS The proportion of HPV+ women directly referred to colposcopy varied across programmes (20-57%; average 37%) and so did CIN2+ detection (49-94%; average 77%). Overall, 63% (range 41-75%) of HPV+ were referred to colposcopy either immediately or at HPV repeat. An absolute 10% increase in immediate colposcopy referral resulted in 4.2% (95% CI: 3.3-5.1%) increase in overall referral. An absolute 10% increase in cytology's sensitivity resulted in a 1.1% (95% CI: 0.1-2.0%) increase in overall CIN2+ detection. CONCLUSIONS Repeat HPV testing limits the effect of subjectivity of cytology interpretation on overall referral and sensitivity. These will change only slightly when replacing cytology with another test if the interval to HPV repeat remains unchanged.

Abstract
AIM In 2013, the Local Health Unit Roma 2 ex C screening laboratory introduced a new set of indicators for quality assurance. We compare 2 sets of indicators based on routine multiple readings (peer review) for their ability to identify problems in single-reader accuracy. METHODS All suspect slides were blindly reviewed by all the cytologists of the laboratory. The standard set of indicators includes interreader Cohen's kappa, positivity rate and atypical squamous cell of undetermined significance/squamous intraepithelial lesion (ASC-US/SIL) ratio. The new set included sensitivity for cervical intraepithelial neoplasia of grade 2 or worse (CIN2+), positive predictive value (PPV) and percentage of positive high-risk (HR)-HPV cases among ASC-US. In order to estimate sensitivity and PPV, we considered all women for whom there was a consensus of negative cytology, negative HR-HPV test, negative colposcopy or negative histology true negative. RESULTS Kappa values ranged from 0.521 to 0.753, with narrow 95% confidence intervals (CIs). Positivity rate ranged from 73.9 to 85.7 and the ASC-US/SIL ratio from 0.61 to 0.81. Sensitivity for CIN2+ at the low-grade SIL threshold ranged from 85.8 to 94.2, PPV ranged from 14.8 to 19.4, and both had a broad 95% CI. Readers with low sensitivity did not show low kappa values. The percentage proportion of HR-HPV-positives (HR-HPV+) among ASC-US ranged from 39.9 to 43.8% with a narrow 95% CI. CONCLUSION The proportion of HR-HPV+ among ASC-US cases is a powerful indicator to address in training.

Abstract
BACKGROUND Atypical squamous cells of undetermined significance (ASCUS) is a term that refers to inflammatory, reactive and reparative processes which are atypical and of higher level and insufficient to be classified as cervical intraepithelial lesions (CIN). AIMS Examine of frequency of HPV infection in ASCUS lesions and regression, stagnation and progression during six-month period. SUBJECTS AND METHODS Prospective study was conducted over a period of 3 years. In private gynecological ambulance "Dr Mahira Jahic". Analysis of PAP smears and HPV typization have been done in 50 patients and PAP test has been repeated after six months. X² test was used for statistical analysis. RESULTS Analysis of 1784 PAP smears showed normal results in 86,6% (N-1530), and abnormal in 13% (N-254). ASCUS in 7,4% (N-133) and ASC-H in 0,5% (N-9), LSIL in 4,4% (N-80), HSIL in 1,3% (N-24), CIN II in 1,2% (N-20), CIN III in 0,2% (N-4). Progression occurred in 18% (9), persistence in 74% (37) and regression in 8%. Patients with ASC-H lesion 0,5% (N-9), PH results showed 22% (N-2) Carcinoma in situ, 33% (N-3) CIN II, 22% (N-2) CIN I and 22% (N-2) chronic cervicitis. Patients with CIN I in 88% (N-7) were positive on HPV of high risk. Patients with persistent ASCUS result were positive in 51% (N-19). The number of CIN I lesions found in women with ASCUS is bigger and statistically significant (p<0,05) in relation to number of CIN I findings found in regular examinations. CONCLUSION Monitoring women with ASCUS lesion, especially HPV positive to high risk group is the best way of selection of women who should be treated and monitored in order to prevent cervical cancer.

Abstract
OBJECTIVES To estimate the frequency of human papillomavirus (HPV) infection and the genotype distribution of HPV among women with a Pap smear showing atypical squamous cells of undetermined significance (ASC-US) attending the Program for the Detection and Control of Cervical Cancer in Bogotá, Colombia. STUDY DESIGN Cervical samples from 200 women with an ASC-US Pap smear were analyzed for the presence of HPV DNA and genotype distribution using a commercial molecular technique (Linear Array®; Roche Molecular Systems, USA). RESULTS HPV infection was found in 140 women (70%). High-risk HPV types were present in 46.4% of the samples; 16.4% showed a low-risk HPV type, and 37.1% showed both. Of the positive samples, 42.9% were infected with a single viral genotype, whereas 57.1% exhibited multiple HPV infections. The most common HPV genotypes were HPV 16, 53, and 52 with a prevalence of 26.4, 16.4, and 13.6%, respectively. CONCLUSION The epidemiological characterization of HPV infections described in this study might guide actions for epidemiological surveillance to strengthen the program in Bogotá and to develop appropriate HPV vaccination programs.

Abstract
OBJECTIVE This paper describes the study design and baseline characteristics of the study population, including the first 30 829 women who enrolled in the Forwarding Research for Improved Detection and Access for Cervical Cancer Screening and Triage (FRIDA Study). This is a large population based study that is evaluating the performance and cost-effectiveness of different triage strategies for high-risk HPV (hrHPV) positive women in Mexico. MATERIALS AND METHODS The target population is more than 100 000 women aged 30 to 64 years who attend the Cervical Cancer Screening Program in 100 health centers in the state of Tlaxcala, Mexico. Since August 2013, all women in the region have been invited to enroll in the study. The study participants are evaluated to determine hrHPV infection using the Cobas 4800 HPV test. The HPV-16/18 genotyping and cytology triage strategies are performed as reflex tests in all hrHPV-positive participants. Women with a positive HPV-16/18 test and/or abnormal cytology (atypical squamous cells of undetermined significance or worse, ASCUS+) are referred for colposcopy evaluation, where a minimum of four biopsies and an endocervical sample are systematically collected. Histologic confirmation is performed by a standardized panel of pathologists. RESULTS Among the 30 829 women who have been screened, the overall prevalence of hrHPV is 11.0%. The overall prevalence of HPV16 and HPV18 are 1.5% and 0.7%, respectively. Cytological abnormalities (ASCUS+) were detected in 11.8% of the hrHPV-positive women. A total of 27.0% (920/3,401) of the hrHPV-positive women were referred to colposcopy because of a positive HPV16/18 test and/or abnormal reflex cytology, (31.6% had only ASCUS+, 53.6% were HPV16/18 positive with a normal cytology result, and 9.5% were positive to both triage tests). CONCLUSION The results of this study will help policy makers and health service providers establish the best practices for triage in cervical cancer screening in Mexico and other countries.

Abstract
BACKGROUND Cervical cancer is the most common cancer in Sub-Saharan Africa. There are little of HIV-infected women one-year after screening using visual inspection with acetic acid (VIA), HPV or cytology in sub-Saharan Africa. METHODS HIV-infected women in Johannesburg South Africa were screened one year later by Pap smear, VIA and human papillomavirus (HPV) testing. Women qualified for the 12 month follow-up visit if they had a negative or cervical intra-epithelial neoplasia (CIN) 1 results at the baseline visit. Modified Poisson regression was used to analyse associations between patient baseline characteristics and progression. RESULTS A total of 688 of 1,202 enrolled at baseline study who were CIN-2+ negative and qualified for a 12 month follow-up visit. Progression to CIN-2+ was higher in women with positive VIA results (12.6%; 24/191) than those VIA-negative (4.4%; 19/432). HPV-positive women at baseline were more likely to progress to CIN-2+ (12.3%; 36/293) than those HPV-negative (2.1%; 7/329). Cytology-positive women at baseline were more likely to progress to CIN-2+ (9.6%; 37/384) than cytology-negative women (2.5%; 6/237). Approximately 10% (10.4%; 39/376) of women with CIN 1 at baseline progressed to CIN 2+. Women who were VIA or HPV positive at baseline were more likely to progress aIRR 1.85, CI 95% (1.46 to 2.36), aIRR 1.41 CI 95% (1.14 to 1.75) respectively. CONCLUSION Progression to CIN-2+ in HIV-infected women is significant when measured by baseline positive VIA, HPV or Pap and yearly screening by any method should be considered in this population if possible.

Abstract
To determine the prevalence of human papillomavirus (HPV) among women with atypical squamous cells of undetermined significance (ASC-US) referred to colposcopy and the implications for clinical management in low- and middle-income countries (LMIC), the present study was conducted. We included 200 women living in Maringa÷Brazil referred to colposcopy service between August 2012 and March 2013 due to an abnormal cytology from ASC-US until high-grade intraepithelial lesion (HSIL). HPV was detected and genotyped by polymerase chain reaction (PCR). The mean age was 36.8±10.5 years, and women with and without ASC-US had similar mean ages (37.4±11.5 and 36.4±9.96 years, respectively). The highest prevalence of ASC-US occurred at 20-24 years (40%). HPV-DNA was positive in 164 (82.0%) women.Of the 57 women with ASC-US, 30 (52.6%) were HPV-DNA-positive and 21 (70%) were high-risk HPV-positive (HR-HPV); the latter was similar to women without ASC-US (76.9%) but with other abnormal cytological findings present. Our data demonstrated that performing tests for HR-HPV can be used for management of women with ASC-US to support the decision of which women should be referred for an immediate or later colposcopy. The same conclusions can be applied to other LMICs for which HPV testing for primary screening has not been adopted.

Abstract
OBJECTIVE Patients whose cervical cytological exams produced a result of atypical squamous cells of undetermined significance (ASCUS) were asked to undergo human papillomavirus (HPV DNA) genotyping detection to assess the role of HPV infection in ASCUS. MATERIALS AND METHODS This study included 1,219 patients with ASCUS that were randomly divided into two groups. The first group contained 618 patients. These participants underwent colposcopy with cervical biopsy. The remaining 601 underwent colposcopy and biopsy with HPV DNA detection. RESULTS Out of the 56,000 patients with ASCUS who underwent ThinPrep cytology test (TCT) de- tection in the authors' hospitals' gynecological outpatient clinics, 1,604 were diagnosed with ASCUS (2.86%). Among the 1,219 patients with ASCUS, the rate of detection of cervical intraepithelial neoplasia (CIN) and cancerization was 22.89% (279/1,219). Among the 601 patients who underwent HPV testing, 182 were positive for high-risk HPV (30.28%). Among HPV-positive samples, the most common high-risk types were HPV16, and HPV58. The most common low-risk types were HPV6 and HPV 11. The rate of detection among high- risk patients who were positive for HPV and cervical carcinoma with intraepithelial neoplasia was 70.88% (129/182). The rate of detection for HPV-negative patients with cervical cancer with intraepithelial neoplasia was 11.55% (47/407). The rate of detection of high-risk HPV was higher than among patients who had not undergone HPV detection and among patients who were negative for HPV (p < 0.05). CONCLUSION The results of cervical cytological examination showed that the manner of progression from inflammation to cancer could differ considerably. HPV DNA examination is an effective means of categorizing and managing ASCUS.

Abstract
BACKGROUND Cervical cancer is the second most common of malignancy found in Thai women. Human papillomavirus (HPV) infection is a major cause. The objective of the present study was to evaluate the prevalence of HPV infection and association with abnormal cervical cytology in Thai women. MATERIALS AND METHODS This study was conducted at the Gynecologic Clinic, Thammasat University, Pathum Thani, Thailand. A total of 2,144 cases who underwent annual cervical cancer screening by co-testing (liquid based cytology and HPV testing, DNA versus mRNA) during the priod from July 2013 to June 2016 were recruited in this study. RESULTS Prevalence of positive high risk (HR) HPV DNA and mRNA test were 19.7 and 8.4%, respectively with a statistically significant difference. Majority of cases of abnormal cytology in this study were atypical squamous cells of undetermined significance (ASC-US). In patients with ASC-US, positive HR HPV DNA was greater than in the mRNA group (10.1 and 4.5%, p<0.001). Nonetheless, there was no significant difference in participants with cervical intraepithelial neoplasia (CIN). HPV mRNA test had slightly lower sensitivity but higher negative predictive value (NPV) than the DNA test to detect abnormal cytology during cervical cancer screening (p<0.001). Both HPV test (DNA and mRNA) had equally efficacy to detect high grade precancerous lesion or higher (CIN 2+). CONCLUSIONS Prevalence of HR HPV DNA and mRNA were 19.7 and 8.4 percent, respectively. NPV of HPV mRNA was higher than DNA test. Both tests had equal efficacy to detect CIN 2+ with sensitivity and specificity of 63% vs 55.7% and 83% vs 92%, respectively.

Abstract
PURPOSE The authors aimed to detect immediate risk of having high grade squamous lesions (HSIL) in atypical squamous cells of uncertain significance(AS-CUS) and concomitant high-risk human papillomavirus (HrHPV) testing as negative [HrHPV(negative)AS-CUS]. MATERIALS AND METHODS The authors performed immediate/baseline colposcopy on concomitant HrHPV (negative)AS-CUS cases. Pap tests were evaluated with liquid-based cytology (LBC) and HrHPV detection was performed in LBC material with PCR. Colposcopic diagnoses and biopsy results were compared with Pap test and HrHPV test results. RESULTS There were 104 patients over a one-year period. In all, 84 cases were included. Colposcopic biopsies revealed low grade squamous intraepithelial lesion (LSIL) in 19 cases (23%) and HSIL in three cases (4%). Intrauterine device use and smoking were significantly correlated with presence of HSIL (p = 0.005 and p = 0.007 respectively). CONCLUSION Similar data in literature, 4% of ASC-US-HrHPV (negative) cases are expected to have HSIL in follow-up periods less than six months. The present authors believe clinicians should be more open with their patients about limitations of Pap-HPV testing.

Abstract
PURPOSE To study the prevalence of CIN2+ diagnosis in women with atypical Papaniculoau (Pap) smears to suggest appropriate management option for Thai health care. MATERIALS AND METHODS Data from all patients with liquid based cytology with human papillomavirus (HPV) testing between May 2013 - May 2016 were collected from medical records. Women with atypical cervical Pap smears were recruited. Results for age, HPV testing, HPV 16, 18, 45 and other genotypes tested, colposcopic examination and histopathological assessment were all collected. Atypical smears were defined as atypical squamous cells of undetermined significance (ASC-US) and atypical squamous cells cannot be exclude high grade squamous intraepithelial lesion (ASC-H). RESULTS A total of 2,144 cases were recruited. Twenty six women with ASC-US on cytology had high risk (HR) HPV detection while eight cases with ASC-H had HR-HPV (40.0% VS 72.7%, p=0.005). Among the 26 women with ASC-US cytology and positive HR-HPV, HPV type 16 (n=8, 30.8%), type 18 (n=1, 3.8%), type 45 (n=1, 3.8%) and other HPV types (n=17, 65.4%) were found. Eight women with ASC-H and positive HR-HPV demonstrated type 16 (n=6, 75%) and other HPV types (n=2, 25%). Fifty seven women with ASC-US had normal colposcopy, CIN1 and CIN2+ at percentages of 80.7 (46/57), 14.0 (8/57) and 5.3 (3/57), respectively. In the ASC-H group, 7 out of 10 women had normal colposcopy and three (30%) had CIN2+ results. CONCLUSIONS In women with ASC-US cytology, immediate colposcopy is highly recommended. HPV testing can be performed if colposcopy is not an available option because there was high prevalence (5.3%) of CIN2+ in our findings. ASCCP recommendations for ASC-H that colposcopy should be performed on all ASC-H cases regardless of HPV result are thereby supported by the findings of this investigation.

Abstract
OBJECTIVE Individuals are often infected with multiple genotypes of human papillomavirus (HPV) simultaneously, but the role these infections play in the development of cervical disease is not well established. This study aimed to determine the association of multiple HPV infections with high-risk cervical lesions (hrCLs). STUDY DESIGN HPV genotyping was performed on 798 SurePath specimens collected between December 1, 2009, and April 30, 2011. The cases were classified as hrCL (n = 90) or non-hrCL (n = 708) based on cytology diagnoses. The association between hrCL and HPV infection patterns was analyzed. RESULTS Multiple HPV infections were frequently encountered (38.2%) in the cohort. Increased frequency of hrCLs was associated with a single high-risk HPV (hrHPV) infection. An additive or synergistic effect was not observed for hrCL in multiple HPV infections. The hrCL rates appeared to decrease in various patterns of multiple HPV infections, but the reduction was not statistically significant. CONCLUSIONS Multiple HPV infections are common with no additive or synergistic effect on the development of hrCL. Conversely, reduced hrCL rates were observed in various patterns of multiple HPV infections compared to their single-genotype infection counterparts, suggestive of possible intergenotypic competition or more effective immune response triggered by multiple infections. Further studies in larger cohorts are needed.

Abstract
OBJECTIVE To evaluate the role of human papillomavirus (HPV) genotyping in predicting the risk of cervical precancerous lesions or cancer in women with minor abnormal cytology. METHODS AND MATERIALS This study was conducted on 329 women with atypical squamous cells of undetermined significance (ASC-US) and 77 women with low-grade squamous intraepithelial lesions (LSIL) out of a total of 4,215 participants in a multicenter, cross-sectional study. Liquid-based cytology and the Hybrid Capture 2 test (HC2) were used to screen eligible women, and a Linear Array HPV genotyping test was performed on women with positive HC2 results. RESULTS The sensitivity and specificity for detecting cervical intraepithelial neoplasia grade 2 or worse (CIN2+) based on HPV 16/18 were 82% [95% confidence interval (CI): 52-95%] and 91% (95% CI: 87-94%) in women with ASC-US and 67% (95% CI: 35-88%) and 84% (95% CI: 73-91%) in women with LSIL. The women infected with HPV 16/18 had a significantly higher risk of developing CIN2+ than those infected with other high-risk HPV types in both the ASC-US (OR 9.93, 95% CI: 2.02-48.88) and LSIL (OR 7.45, 95% CI: 1.60-34.68) arms. CONCLUSIONS Genotyping for HPV 16/18 greatly improves specificity, but at the expense of potential sensitivity in the triage of minor cytology abnormalities. The role of genotyping for HPV 16/18 in order to triage women with minor abnormal cytology should be further evaluated in future studies.

Abstract
AIM To determine if positive dual staining of p16/Ki-67 in cytology samples from women with atypical squamous cells of undetermined significance (ASC-US), low-grade squamous intraepithelial lesion (LSIL) or normal cytological reports with presence of high-risk human papillomavirus (HPV), helps in predicting the risk of developing high-grade cervical lesions during one-year of follow-up after a normal initial colposcopy. MATERIALS AND METHODS One-hundred and sixty women with ASC-US, LSIL or otherwise normal cytology, but with the presence of high-risk HPV, were referred to the colposcopy Unit of our Hospital. Cytology and HPV testing were repeated and dual staining of p16/Ki-67 performed on a new cytological specimen, and subsequently patients were colposcopically assessed and prospectively followed-up for one year, after which the colposcopy was repeated. An optional intermediate colposcopical assessment after six months was also offered. RESULTS Out of 143/160 women with a normal initial colposcopy, 13 were ultimately lost to follow-up. Out of the remaining 130, nine developed histologically verified cervical intraepithelial neoplasia or higher grade (CIN2+) lesions during the one-year follow-up period. Two thirds of them (6/9) were initially p16/Ki-67-positive. CONCLUSION Biomarker detection may identify women at higher risk of CIN2+, and these women may benefit from early colposcopic assessment. Women who test negatively for the biomarkers could eventually follow a less aggressive protocol.

Abstract
BACKGROUND Current guidelines recommend initial colposcopy with biopsy regardless of human papillomavirus (HPV) test results in women with atypical squamous cells, cannot exclude high-grade squamous intraepithelial lesion (ASC-H). The purpose of this study was to evaluate the value of HPV testing in women with ASC-H based on colposcopic pathology results. MATERIALS AND METHODS A multicenter cross-sectional study was carried out at three academic hospitals and involved 40,847 Korean women who underwent cervical cancer screening with cytology and HPV tests with or without subsequent colposcopic biopsies between January 2007 and December 2013. RESULTS ASC-H was diagnosed in 276 women (0.7%). Only 6 of 68 (8.8%) women with ASC-H who were HPV negative had cervical intraepithelial neoplasia grade ≥2 (CIN ≥2) lesions, whereas 47.4% of the women with ASC-H who were HPV positive had CIN ≥2 lesions. No cases of invasive cervical cancer were diagnosed among women with ASC-H who were HPV negative. Logistic regression analysis was performed using the group with normal Papanicolaou test results and HPV-negative status as the reference group. Women with ASC-H who were HPV positive had a significantly increased risk of CIN ≥2 lesions, whereas no significant increase was observed in patients with ASC-H and HPV-negative status. CONCLUSION If the result of the HPV test was negative, the risk of CIN ≥2 lesions in Korean women with ASC-H cytology was low. Reflex HPV testing should be an option for the management of women with cytology showing ASC-H to decrease unnecessary colposcopic biopsies, which are expensive and invasive. IMPLICATIONS FOR PRACTICE Current American Society for Colposcopy and Cervical Pathology guidelines recommend universal colposcopy for the management of women with atypical squamous cells, cannot exclude high-grade squamous intraepithelial lesion (ASC-H) on cytology, regardless of human papillomavirus (HPV) test results. The present study suggested that HPV cotesting in patients with ASC-H cytology can provide more detailed and useful information regarding the risk of high-grade cervical intraepithelial neoplasia (CIN) lesions and the need for further treatment. When the result of the HPV test was negative, the risk of CIN lesions of grade ≥2 in women with ASC-H cytology was low. Consequently, reflex HPV testing, rather than immediately performance of invasive and expensive colposcopy with biopsy, should be an option for the management of women with ASC-H.

Abstract
High risk types of human papillomaviruses E6/E7 oncogenes and their association with tumor suppressor genes products are the key factors of cervical carcinogenesis. This study proposed them as specific markers for cervical dysplasia screening. The aim of the study is to compare the clinical and prognostic significance of HPV E6/E7 mRNA as an early biomarker versus HPV DNA detection and cytology in triage of woman for cervical cancer. The study group consists of 413 women: 258 NILM, 26 ASC-US, 81 LSIL, 41 HSIL, and 7 unsatisfactory cytology. HPV4AACE screening, real-time multiplex PCR and MY09/11 consensus PCR primers methods were used for the HPV DNA detection. The real-time multiplex nucleic acid sequence-based assay (NucliSENS EasyQ HPV assay) was used for HPV E6/E7 mRNA detection of the five most common high risk HPV types in cervical cancer (16, 18, 31, 33, and 45). The results show that HPV E6/E7 mRNA testing had a higher specificity 50% (95% CI 32-67) and positive predictive value (PPV) 62% (95% CI 46-76) for CIN2+ compared to HPV DNA testing that had specificity of 18% (95% CI 7-37) and PPV 52% (95% CI 39-76) respectively. The higher specificity and PPV of HPV E6/E7 mRNA testing are valuable in predicting insignificant HPV DNA infection among cases with borderline cytological finding. It can help in avoiding aggressive procedures (biopsies and over-referral of transient HPV infections) as well as lowering patient's anxiety and follow up period.

Abstract
OBJECTIVES To establish the prevalence of cervical cytology abnormalities, determine the correlation between CD4+ cell count and abnormal Pap smear, determine the correlation between WHO-HIV staging and abnormal pap smear among HIV infected women attending HIV clinic at Rwanda Military Hospital. DESIGN Cross-sectional descriptive study. SETTING Rwanda Military Hospital Kigali, Rwanda. SUBJECTS All HIV-positive women, 18-69 years who had been or were sexually active and were attending the HIV-clinic and consented to participate in the study. RESULTS Two hundred and ninety three women infected with HIV had cervical smear taken for cytology. Of the 293 women who were recruited for the study, cervical Squamous Intra epithelial Lesion (SIL) were present in 58 (20%). Of those with cervical SIL, 33 (56.89%) women had low-grade SIL, 15 (25.86%) had Atypical Squamous Cells of Undetermined Significance (ASCUS), six (10.34%) had high-grade SIL, three (5.17%) had Squamous cell carcinoma (SCC) and one (1.72%) had Atypical Glandular Cells of Undetermined Significance (AGUS). In the current study, use of ARV drugs was not associated with a reduction in the risk of cervical SIL. CONCLUSION A high prevalence of cervical SIL was found among HIV-infected women at Rwanda Military Hospital. Increased immune suppression was significantly associated with cervical SIL.

Abstract
Cervical screening by using cytology was proven efficient in reducing the mortality secondary to cervical cancer, but this method has limitations. High risk HPV infection is essential for cervical cancer development so HPV testing is a new tool used for screening patients for cervical neoplasia. HPV testing was proven most useful for women over 30 years old, in cases in which cytology identified ASC-US and after treatment for CIN. This article outlines the clinical significance of HPV-DNA testing for precancerous cervical lesions and the evidence that stands behind these recommendations.

Abstract
BACKGROUND The cytological interpretation of ASC-US represents a category of morphologic uncertainty. For patients with this result, other tests are necessary in order to determine the risk for cervical lesions. MATERIALS AND METHODS 198 patients with ASC-US cytology have been analyzed between 2008 and 2013. All the patients included in the study have subsequently had a high oncogenic HPV testing and colposcopy risk. 103 (52%) patients tested positive for high risk HPV and 21 (10%) had associated colposcopy changes and precancerous and cancerous lesions identified through biopsy. 95 (48%) patients tested negative for HPV and none of these women had lesions at colposcopy. RESULTS AND DISCUSSION High oncogenic risk HPV testing was proven useful in identifying the patients with ASC-US cytology who are at high risk for cervical lesions (100% sensibility). In this study, the HPV testing had a negative predictive value of 100%, which uselessly renders a further colposcopy evaluation. HPV testing for women with ASC-US is not specific in identifying women with cervical lesions (Specificity 53%) and this results from a high prevalence of limited HPV infections in an age group which is less than 30 years old. CONCLUSIONS High risk HPV testing for women with ASC-US cervical cytology is useful in determining the risk for precancerous and cancerous cervical lesions. A positive result is associated with a high risk for cervical lesions (20%) and for these patients colposcopy is necessary. For women with a negative result, the risk for cervical lesions is practically null so colposcopy is not required.
