Abstract
OBJECTIVES Human papillomavirus (HPV) primary testing for cervical screening is being implemented around the world. We explored HPV awareness, and knowledge about primary screening in Great Britain (England, Scotland and Wales), where it has been in place for several years, ahead of extended screening intervals being implemented in England. SETTING/METHODS Women aged 18-70 (n = 1995) were recruited by YouGov from their online panel in August 2022. The weighted sample (n = 1930) was population-representative by age, region, education and social grade. We measured HPV awareness, knowledge (excluding those unaware of HPV) using eight true/false items, and understanding of the role of HPV testing in cervical screening. RESULTS Overall, 77.6% (1499/1930) of women were aware of HPV. When asked to identify the statement describing how cervical screening works, only 12.2% (236/1930) correctly selected the statement reflecting HPV primary screening (13.5% (194/1436) in screening-eligible women). Excluding those unaware of HPV, most participants had heard about the virus in the context of cervical screening (981/1596; 61.5%) or HPV vaccination (1079/1596; 67.6%). Mean knowledge score was 3.7 out of 8 (SD = 2.2) in this group. Most knew that an HPV-positive result does not mean a woman will definitely develop cervical cancer (1091/1499; 72.8%) but far fewer were aware of the long timeline for HPV to develop into cervical cancer (280/1499; 18.7%). CONCLUSIONS Only three-quarters of women in Britain are aware of HPV, and knowledge of primary screening is very low, even among screening-age women. This points to continued need for awareness-raising campaigns to ensure informed choice about screening and mitigate public concern when screening intervals are extended.

Abstract
Vaccination against human papillomavirus (HPV) is changing the performance of cytology as a cervical screening test, but its effect on HPV testing is unclear. We review the effect of HPV16/18 vaccination on the epidemiology and the detection of HPV infections and high-grade cervical lesions (CIN2+) to evaluate the likely direction of changes in HPV test accuracy. The reduction in HPV16/18 infections and cross-protection against certain non-16/18 high-risk genotypes, most notably 31, 33, and/or 45, will likely increase the test's specificity but decrease its positive predictive value (PPV) for CIN2+. Post-vaccination viral unmasking of non-16/18 genotypes due to fewer HPV16 co-infections might reduce the specificity and the PPV for CIN2+. Post-vaccination clinical unmasking exposing a higher frequency of CIN2+ related to non-16/18 high-risk genotypes is likely to increase the specificity and the PPV of HPV tests. The effect of HPV16/18 vaccination on HPV test sensitivity is difficult to predict based on these changes alone. Programmes relying on HPV detection for primary screening should monitor the frequency of false-positive and false-negative tests in vaccinated (younger) vs. unvaccinated (older) cohorts, to assess the outcomes and performance of their service.

Abstract
Objective: To investigate the performance of human papilloma virus (HPV) typing as a triage tool in the management of patients with postcoital bleeding (PCB). Methods: All patients referred for colposcopy at a cervical pathology clinic of a nationwide health insurance organization, due to PCB and had a preceding high-risk HPV (hrHPV) test between 2018 and 2020, were retrospectively located. Demographic and pathologic data were collected from electronic medical files. Sensitivity, specificity, and negative and positive predictive value of hrHPV test according to final pathology were calculated. Results: Three hundred ninety patients referred for colposcopy due to PCB with a preceding hrHPV test were located. HrHPV-positive patients were significantly younger (33.7 ± 10 vs. 37.2 ± 9, p < 0.006) with a higher proportion of nulliparous, nonmarried, and smokers compared with hrHPV-negative patients (75% vs. 47%, p < 0.001; 75.4% vs. 45.1%, p < 0.001; and 24.6% vs. 12.8%, p < 0.028, respectively). No case of high-grade cervical intraepithelial neoplasia (CIN2/3) was identified among hrHPV-negative patients. The sensitivity and NPV of the hrHPV test for high-grade cervical lesions were both 100%, decreasing to 36% and 95%, respectively, for any cervical dysplasia (CIN1/CIN2/CIN3). Adding cytology to HPV typing had a negligible effect on test performance. At univariate analysis, age, HPV vaccine status, nulliparity, and positive HPV typing were independently associated with cervical dysplasia. At multivariate analysis, only positive HPV typing remained significantly associated with cervical dysplasia (hazard ratio 2.75, confidence interval 1.1-6.5, p = 0.023). Conclusion: A negative HPV test even in the presence of PCB may rule out cervical dysplasia with extremely high accuracy and may save unnecessary colposcopies.

Abstract
BACKGROUND Cervical cancer is a major global health concern, disproportionately affecting women in developing countries. Cervical cancer has two primary subtypes, squamous cell carcinoma (SCC) and adenocarcinoma (AC), each with distinct characteristics and screening effectiveness. In this study, we aimed to estimate the global incidence of cervical cancer according to histological subtype to inform prevention strategies. METHODS Using data from population-based cancer registries, we computed the rates of SCC, AC, and other specified histology among all cervical cancer cases by country and by 5-year age group. Proportions were subsequently applied to the estimated number of cervical cancer cases from the Global Cancer Observatory 2020. Age-standardized incidence rates were calculated. RESULTS SCC accounted for 82.72% of global cervical cancer cases, with AC contributing 12.18%. The highest SCC incidence was in Sub-Saharan Africa (29.79 per 100,000 population). The AC incidence was highest in South-Eastern Asia (3.67 per 100,000 population). Age-specific trends showed SCC peaking at approximately age 55 years and AC plateauing after age 45 years. CONCLUSIONS This study provided a comprehensive estimate of cervical cancer incidence by histological subtype. SCC remained the dominant subtype globally, whereas the incidence of AC varied across regions. These findings highlighted the need for tailored prevention strategies, especially testing for human papillomavirus to detect AC in high burden areas.

Abstract
With the rising need for accessible cervical cancer screening, self-sampling methods offer a promising alternative to traditional physician-led sampling. This study aims to evaluate the efficacy of the HygeiaTouch Self Sampling Kit for Women in detecting human papillomavirus (HPV) types and predicting cervical lesions. We studied the concordance in identifying high-risk HPV (hrHPV) types between samples collected by physicians and those self-collected by women using a self-sampling kit for validation. Women aged 21-65, fitting into specific categories based on their cervical health history were eligible. Cohen's kappa coefficient to gauge concordance between the two specimen types and relative accuracy metrics in identifying cervical intraepithelial neoplasia (CIN) were also calculated, with physician-sampled specimens serving as a reference. A total of 1210 participants from three institutes were involved. The self-sampling kit closely matched the physician-led method in terms of collecting valid specimens (100% vs. 100%), identifying hrHPV types (kappa: 0.75, 95% confidence interval [95% CI]: 0.72-0.79; agreement: 87.7%, 95% CI: 85.8-89.6) and predicting CIN grade 2 or worse (CIN2+) (relative sensitivity: 0.949, relative accuracy: 0.959). Kappa values varied between 0.71 and 0.83 for different hrHPV types and combinations, with an overall value 0.75 (95% CI: 0.72-0.79) signifying robust compatibility between the two methods. Our study underscores the potential of the HygeiaTouch Self Sampling Kit as a reliable, efficient, and user-friendly alternative to traditional sampling methods. This suggests that self-sampling could be pivotal in expanding cervical cancer screening accessibility and enhancing detection rates.

Abstract
AIM In Japan, primary human papilloma virus (HPV) testing has not been introduced for cervical cancer screening due to concerns that HPV-negative lesions may be missed and a lack of Japanese data. The purpose of this study was to evaluate the validity of primary HPV testing in Japan by analyzing cervical intraepithelial neoplasia 2 (CIN2) or more/high-risk HPV- (CIN2+/hrHPV-) cases in cervical cancer screening. METHODS Data from 35 525 cervical cancer screenings with HPV testing and cervical cytology from 2011 to 2019 in Saga City, Japan, were reviewed. The cases with low-grade squamous intraepithelial lesion (LSIL+)/hrHPV- were analyzed in detail. RESULTS The results of the 35 525 examinees were as follows: 31 123 were negative for intraepithelial lesion or malignancy (NILM)/hrHPV-, 2612 were NILM/hrHPV+, 262 were atypical squamous cells of undetermined significance (ASC-US)/hrHPV-, 213 were ASC-US/hrHPV+, 291 were LSIL+/hrHPV-, and 1024 were LSIL+/hrHPV+. Of the 256 LSIL+/hrHPV- examinees for whom histology was available, CIN2+ were CIN2 9.4% (24/256), CIN3 3.9% (10/256), cervical adenocarcinoma 0.4% (1/256), uterine corpus cancer 1.2% (3/256), and uterine sarcoma 0.4% (1/256). Overall, the rate of LSIL+/hrHPV- was 0.82% (291/35.525), 0.1% (36/35525) of which were cervical lesions with CIN2+. Only one cervical adenocarcinoma was detected, but gastric-type adenocarcinoma was not included. CONCLUSION HPV-negative CIN2+ or cervical adenocarcinoma is not a concern for the introduction of primary HPV screening in Japan. Primary HPV testing in cervical cancer screening is considered a feasible method that can be used in Japan, although an algorithm suitable for Japan and a national-level management system need to be established.

Abstract
BACKGROUND Many low- and-middle-income countries are disproportionately burdened by cervical cancer, resulting in high morbidity and mortality. HPV-DNA testing coupled with treatment with thermal ablation is a recommended screening and precancer treatment strategy, but not enough is known about how this can be effectively implemented in the context of integrated services. The (Scale Up Cervical Cancer Elimination by Secondary prevention Strategy, (SUCCESS) project is conducting a study to understand this approach, integrated into existing women's health services in Burkina Faso, Cote d'Ivoire, Guatemala, and the Philippines (2020-2024). METHODS A hybrid effectiveness-implementation type III mixed-methods observational study design is used to assess feasibility, acceptability, and costs of integrated service delivery in 10 sites per country, selected considering urban/rural location, facility level, onsite/offsite laboratories, and health services type. In each country, a sample size of 2227 women aged 25-49 years will be enrolled with about 20% being women living with HIV. The primary outcome is proportion of HPV positive women completing precancer treatment, if eligible, within three months of screening. Data collection and analysis includes; facility and client exit surveys, key informant and client interviews, registries and project records extractions, and costing data analysis. Analysis includes descriptive statistics, context description, thematic analysis, and document analysis. Quantitative analyses will be stratified by participant's HIV status. DISCUSSION Recruitment of study participants started in April 2022 (Burkina Faso and Côte d'Ivoire) and August 2022 (Guatemala and the Philippines). Enrolment targets for women screened, client exit, in-depth and key informant interviews conducted were reached in Burkina Faso and Cote d'Ivoire in November 2022. Guatemala and Philippines are expected to complete enrolment by June 2023. Follow-up of study Participants 12-months post-treatment is ongoing and is expected to be completed for all countries by August 2024. In LMICs, integrating cervical cancer secondary prevention services into other health services will likely require specific rather than incidental recruitment of women for screening. Reconfiguration of laboratory infrastructure and planning for sample management must be made well in advance to meet induced demand for screening.

Abstract
OBJECTIVES Approximately 1% to 2% of routine cytologic specimens collected for Papanicolaou testing are unsatisfactory for evaluation. The American Society for Colposcopy and Cervical Pathology 2019 guidelines recommend repeat testing within 2 to 4 months of an unsatisfactory Papanicolaou test (UPT) result. METHODS We evaluated the utility of follow-up Papanicolaou testing, human papillomavirus (HPV) testing, and biopsy in 258 cases of UPTs. RESULTS High-risk HPV testing was positive in 17.4% (n = 45) and negative in 82.6% (n = 213) of cases at the time of initial UPT; 8.1% (n = 21) of cases had discordant HPV test results. Similarly, 3.8% (n = 8) of initially HPV-negative cases were reported to be HPV-positive on follow-up; 28.9% (n = 13) of initially HPV-positive cases were reported to be HPV negative on follow-up. In total, 27.1% (n = 70) of cases underwent biopsy. Biopsies with significant findings were present in 40% (n = 12) of HPV-positive cases and 7.5% (n = 3) of HPV-negative cases. Low-grade squamous intraepithelial lesion (LSIL) (low-grade cervical intraepithelial neoplasia [CIN-1]) was the most significant finding in all 3 HPV-negative biopsies; 58.3% (n = 7) of HPV-positive biopsies showed LSIL (CIN-1), 13.3% (n = 4) showed HSIL (high-grade CIN), and 3.3% (n = 1) showed invasive carcinoma. The sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of concurrent HPV testing at the time of UPT for predicting follow-up HPV test result within 1 year of initial UPT are 80.0%, 94.0%, 71.1%, and 96.2%, respectively. The sensitivity, specificity, PPV, and NPV of initial HPV test results for predicting follow-up Papanicolaou test results are 67.7%, 89.7%, 48.8%, and 95.0%, respectively. RESULTS Concurrent HPV testing in the setting of UPT can be a sensitive tool for predicting follow-up HPV status and significant findings of squamous intraepithelial lesions on follow-up Papanicolaou tests and biopsy.

Abstract
BACKGROUND Women living with human immunodeficiency virus (HIV) (WLWH) are more likely to be infected with the oncogenic human papillomavirus (HPV). We assessed the prevalence of high-risk (HR) (16/18/31/33/35/39/45/51/52/56/58/59/68/73/82), probable high-risk (pHR) (26/53/66), and low-risk (LR) (6/11/40/42/43/44/54/61/70) HPV types and their associated risk factors. METHODS This cross-sectional study of WLWH aged 18-64 years included one laboratory and eight HIV-specialty healthcare facilities in the pilot network. Descriptive statistics were used to assess sociodemographic and behavioral characteristics. Adjusted analyses were conducted to evaluate risk factors associated with HR and/or pHR HPV infection in WLWH. RESULTS From May/2021 to May/2022, 1,914 (92.5%) WLWH participated in the pilot study and had valid HPV-DNA results of self-collected vaginal samples. The median age of the participants was 45 years, 60.1% had ≥ 9 years of schooling, 80.5% were ≤ 18 years at first sexual intercourse, and 51.7% had > 4 sexual partners throughout life. The prevalence of any HPV type, HR HPV, pHR HPV, and LR HPV was 65.8%, 49.6%, 16.7%, and 40.0%, respectively. Age was inversely associated with pHR and/or HR-HPV (p < 0.001), and education level was inversely associated with HR-HPV (p = 0.003) types. Any HR or pHR was associated with being single (p = 0.029) and exchanging sex for drugs (p = 0.037). CONCLUSIONS The prevalence of HPV, especially HR HPV, among WLWH is high in Brazil, highlighting the need for HPV screening in this population. Self-collection of vaginal samples is an important strategy for increasing testing access.

Abstract
BACKGROUND The transition of Australia's National Cervical Screening Program from cytology to a molecular test for human papillomavirus (HPV) (locally referred to as the 'Renewal'), including a longer five-year interval and older age at commencement, significantly impacted all sectors of program delivery. The Renewal had major implications for the roles and requirements of pathology laboratories providing services for the Program. This study aimed to understand the early impacts of the Renewal and its implementation on the pathology sector. METHODS Semi-structured qualitative interviews were conducted with key stakeholders (N = 49) involved in the STakeholder Opinions of Renewal Implementation and Experiences Study (STORIES), 11-20 months after the program transition. A subset of interviews (N = 24) that discussed the pathology sector were analysed using inductive thematic analysis. RESULTS Four overarching themes were identified: implementation enablers, challenges, missed opportunities, and possible improvements. Participants believed that the decision to transition to primary HPV screening was highly acceptable and evidence-based, but faced challenges due to impacts on laboratory infrastructure, resources, staffing, and finances. These challenges were compounded by unfamiliarity with new information technology (IT) systems and the new National Cancer Screening Register ('Register') not being fully functional by the date of the program transition. The limited availability of self-collection and lack of standardised fields in pathology forms were identified as missed opportunities to improve equity in the Program. To improve implementation processes, participants suggested increased pathology sector involvement in planning was needed, along with more timely and transparent communication from the Government, and clearer clinical management guidelines. CONCLUSION The transition to primary HPV screening had a significant and multifaceted impact on the Australian pathology sector reflecting the magnitude and complexity of the Renewal. Strategies to support the pathology sector through effective change management, clear, timely, and transparent communication, as well as adequate funding sources will be critical for other countries planning to transition cervical screening programs.

Abstract
For the American Cancer Society (ACS), the time for primary human papillomavirus (HPV) screening implementation has unequivocally arrived for the United States, but it will require broad knowledge mobilization and addressing logistical barriers to engage the public and health providers. The ACS is using its convener role and marshalling its considerable educational and knowledge dissemination resources to advance primary HPV screening in the United States and to share best practices from countries that have done the same through the ACS Primary HPV Screening Initiative.

Abstract
Objectives This study was undertaken to study the prevalence of human papillomavirus (HPV) infection using the polymerase chain reaction (PCR) technique in abnormal cervical pap smears and to correlate the different cytological results with HPV infection. Material and Methods A total of 1788 cervical pap smears of women more than 30 years of age conducted over a period of 1 year 3 months (June 2015-August 2016) were screened by liquid-based cytology. High-risk (HR)-HPV testing was performed by PCR in abnormal lesions. Inflammatory smears and some atypical squamous cells of undetermined significance (ASCUS)-reactive cases were excluded from HPV testing. Histopathological correlation was done wherever possible. Results The overall prevalence of the intraepithelial lesions/malignancy was ASCUS. (ASCUS) - 79 (4.42%), atypical squamous cells cannot exclude high-grade squamous intraepithelial lesion (ASC-H) - 10 (0.56%), low-grade squamous intraepithelial lesion (LSIL) - 26 (1.45%), high-grade squamous intraepithelial lesion (HSIL) - 15 (0.84%), squamous cell carcinoma - 5 (0.28%), and adenocarcinoma - 1 case (0.06%). Overall, 136 (7.60%) samples were classified as abnormal. Seventy-seven samples were included for HR-HPV testing - 20 ASCUS, 10 ASC-H, 26 LSIL, 15 HSIL, and 6 malignant cases. A control group of ten samples with normal cervical cytology within the normal limit (Control) (WNLc) was tested for HR-HPV. HR-HPV was detected in 20% of samples of the WNLc group, 45% of the ASCUS group, 70% of the ASC-H group, 73.07% of the LSIL group, 86.67% of the HSIL, and 83.34% of the samples in the malignant group. Overall, HR-HPV was detected in 68.83% of abnormal cervical pap smears. Conclusion Our study shows that the percentage of HR-HPV-positive case increases with the severity of cytologic morphology. HPV had 4 times higher positivity in squamous intraepithelial lesion as compared to ASCUS.

Abstract
Cervical cancer is the fourth most common cancer worldwide, with over 600,000 new cases annually and approximately 350,000 cancer-related deaths per year. The disease burden is disproportionately distributed, with cancer-related mortality ranging from 5.2 deaths per 100,000 individuals in highly-developed countries, to 12.4 deaths per 100,000 in less-developed countries. This article is a review of the current screening recommendations and potential future recommendations.

Abstract
OBJECTIVE Screening with primary human papillomavirus (HPV) testing has been evaluated in highly prescreened populations with lower HPV and HIV prevalence than what is the case in South Africa. High prevalence of HPV and underlying precancer in women living with HIV (WLWH) affect the clinical performance of screening tests significantly. This study investigates the utility and performance of an extended genotyping HPV test in detection of precancer in a population with a high coinfection rate with HIV. METHODS A total of 1,001 women aged 25 to 65 years with no cervical cancer screening in the preceding 5 years were tested with cytology and primary extended genotyping HPV testing. The cohort of 1,001 women included 430 WLWH (43.0%) and 564 HIV-negative (56.3%) women. RESULTS Abnormal cytology (atypical squamous cells of undetermined significance or higher) was significantly higher in WLWH (37.2% vs 15.9%) and high-grade squamous intraepithelial lesion or above (23.5% vs 5.2%). The WLWH also tested positive more often for any HPV type (44.3% vs 19.6%; p < .0001) The specificity for cervical intraepithelial neoplasia 2+ at 91.2% of a combination of HPV types, 16/18/45 (very high risk) and 31/33/58/52 (moderate risk), performed better than cytology or any HPV-positive result to predict cervical intraepithelial neoplasia 3+ on histology. The additional genotype information supports direct referral to treatment or colposcopy in a larger proportion of the screen-positive population. CONCLUSIONS The potential contribution of extended genotyping is demonstrated. The ideal choice of sensitivity and specificity ultimately depends on the health budget. More information will allow a screening algorithm, guiding management according to risk.

Abstract
Testing for high-risk human papillomavirus (HPV) as part of primary cervical cancer screening has become more common recently. The Cobas 6800, an FDA-approved cervical screening platform, detects 14 high-risk HPVs, including HPV16 and HPV18. However, this test is limited to only women, which leads to low screening rates in trans men and other non-binary people. The cervical screening of trans men and other genders, especially those lying on the female-to-male spectrum, is equally important. Furthermore, cisgender males, particularly homosexuals, are also prone to chronic HPV infections and serve as HPV carriers, transmitting it to women and other men through sexual contact. Another limitation of the test is its invasive specimen collection, which induces discomfort and genital dysphoria. Therefore, there is a need for an innovative, less invasive method that would allow the sampling process to be more comfortable. In this study, we assess the performance of the Cobas 6800 for high-risk HPV detection in urine samples spiked with HPV16, HPV18, and HPV68. The limit of detection (LOD) was calculated using a dilution series (1.25-10,000 copies/mL) over a course of three days. Furthermore, the clinical validation was performed by calculating sensitivity, specificity, and accuracy. The limit of detection ranged from 50-1000 copies/mL depending upon the genotype. Moreover, the urine test demonstrated a high clinical sensitivity of 93%, 94%, and 90% for HPV16, HPV18, and HPV68, with 100% specificity. The overall percent agreement was calculated to be 95% for both HPV16 and HPV18, and 93% for HPV68. The high concordance, reproducibility, and clinical performance of the current assay suggest that the urine-based HPV test fulfills the requirements for its use in primary cervical screening. Moreover, it has the potential to be used for mass screening to not only identify high-risk individuals, but also to monitor vaccine effectiveness.

Abstract
In this study, we aimed to document stakeholders' experiences of implementing Australia's renewed National Cervical Screening Program. In December 2017, the program changed from 2nd yearly cytology for 20-69 year olds to 5 yearly human papillomavirus (HPV) screening for women 25-74 years. We undertook semi-structured interviews with key stakeholders including government, program administrators, register staff, clinicians and health care workers, non-government organisations, professional bodies, and pathology laboratories from across Australia between Nov 2018 - Aug 2019. Response rate to emailed invitations was 49/85 (58%). We used Proctor et al's (2011) implementation outcomes framework to guide our questions and thematic analysis. We found that stakeholders were evenly divided over whether implementation was successful. There was strong support for change, but concern over aspects of the implementation. There was some frustration related to the delayed start, timeliness of communication and education, shortcomings in change management, lack of inclusion of Aboriginal and Torres Strait Islander people in planning and implementation, failure to make self-collection widely available, and delays in the National Cancer Screening Register. Barriers centred around a perceived failure to appreciate the enormity of the change and register build, and consequent failure to resource, project manage and communicate effectively. Facilitators included the good will and dedication of stakeholders, strong evidence base for change and the support of jurisdictions during the delay. We documented substantial implementation challenges, offering learnings for other countries transitioning to HPV screening. Sufficient planning, significant and transparent engagement and communication with stakeholders, and change management are critical.

Abstract
BACKGROUND With HPV screening the specificity of screening positives has decreased, even with a cytological triage test. Increases in colposcopies and detection of benign or low-grade dysplasia are reported, not least in older women. These results highlight the necessity to find other triage tests in HPV screening strategies, so that women can be more accurately selected for colposcopy, thus minimizing the clinically irrelevant findings. METHODS The study included 55- to 59-year-old women who exited the screening with normal cytology, but later in a follow-up test were positive for the HPV genotypes 16, 18, 31, 33, 35, 39, 45, 51, 52, 56, 58, 59, 66 and 68 and had a cervical cone biopsy done. To model a screening situation with hrHPV-positive women, three different triage strategies, namely, cytology, genotyping and methylation, were performed. The study considered the effect of direct referral to colposcopy for HPV genotypes 16, 18, 31, 33, 45, 52 and 58, and methylation for FAM19A4 and hsa-mir124-2 and/or any form of abnormal cytology. RESULTS Seven out of 49 women aged 55-59 years with hrHPV had a cone biopsy with high-grade squamous intraepithelial lesion. No triage method found all cases, and when comparing positive and negative predictive value and false negative rate, cytology showed better results than genotyping and methylation. CONCLUSION This study does not support a switch in triage strategies from cytology to hrHPV genotyping and methylation for women above 55 years of age yet, but demonstrates the need for more evidence on molecular triage strategies.

Abstract
The implementation of high-risk human papillomavirus testing (hrHPV testing) as a screening method in substitute for cytology has evoked the need for more sensitive and less objective tests for the triage of HPV-positive women. In a cohort of 1763 HPV-positive women, the potential of immunocytochemical p16 and Ki-67 dual staining as compared to cytology, alone or in combination with HPV partial genotyping, was tested for triage of women attending a cervical cancer screening program. Performance was measured using sensitivity, specificity, and positive and negative predictive values. Comparisons were assessed using logistic regression models and the McNemar test. Dual staining was evaluated in a prospectively collected study cohort of 1763 HPV-screened women. For triage of CIN2+ and CIN3+, NPV and sensitivity, 91.8% and 94.2% versus 87.9% and 89.7%, respectively, were significantly higher using dual staining together with HPV 16/18 positive, as compared to cytology (p < 0.001). The specificities, however, were lower for dual staining as compared to cytology. Conclusions: Dual staining is safer for decision-making regarding HPV-positive women's need for follow-up with colposcopy and biopsy, as compared to cytology.

Abstract
OBJECTIVE Because the specific prevalence and carcinogenesis of non-16/18 high-risk (hr) Human Papillomavirus (HPV) is not fully understood, we designed a study with aim of evaluating the risk of high-grade cervical intraepithelial neoplasia (CIN) in non-16/18 hr-HPV positive/cytology negative cases and assessing the distribution of non-16/18 hr-HPV subtypes. MATERIALS AND METHODS This cross-sectional study was conducted on 138 non-16/18 hr-HPV positive/cytology negative women, who were referred to the gynecologic oncology clinic of Yas hospital, affiliated with Tehran University of Medical Sciences, January 2021 to 2022. RESULTS Among the detected types, HPV 31 was the most frequent type. 63 cases underwent biopsy as indicated based on colposcopic examination with acetic acid 3% application among which 34 had normal results. In the remaining 29 cases, 25 had insignificant findings. CIN2 was reported in 2 cases, one with HPV 31, 45, 58, and the other with HPV 58. CIN3 was also detected in 2 cases, one with HPV 31 and the other with HPV 35, 45. The overall incidence of high-grade CIN was 2.8%. A statistically significant (P-value = 0.046) difference was detected between patients with high-grade CIN compared with the others regarding the Hookah usage. CONCLUSION The risk of CIN among non-16/18 hr-HPV positive/cytology negative cases is noticeably low. Based on ASCCP guidelines return testing at 1 year without immediate colposcopy seems sufficient; however, because of many reasons doing immediate colposcopy rather than 1-year follow-up may be a more accessible approach in resource poor, low-income countries such as ours.

Abstract
PURPOSE Cervical cancer (CC) is caused by a persistent high-risk human papillomavirus (hrHPV) infection. The cervico-vaginal microbiome may influence the development of (pre)cancer lesions. Aim of the study was (i) to evaluate the new CC screening program in Germany for the detection of high-grade CC precursor lesions, and (ii) to elucidate the role of the cervico-vaginal microbiome and its potential impact on cervical dysplasia. METHODS The microbiome of 310 patients referred to colposcopy was determined by amplicon sequencing and correlated with clinicopathological parameters. RESULTS Most patients were referred for colposcopy due to a positive hrHPV result in two consecutive years combined with a normal PAP smear. In 2.1% of these cases, a CIN III lesion was detected. There was a significant positive association between the PAP stage and Lactobacillus vaginalis colonization and between the severity of CC precursor lesions and Ureaplasma parvum. CONCLUSION In our cohort, the new cervical cancer screening program resulted in a low rate of additional CIN III detected. It is questionable whether these cases were only identified earlier with additional HPV testing before the appearance of cytological abnormalities, or the new screening program will truly increase the detection rate of CIN III in the long run. Colonization with U. parvum was associated with histological dysplastic lesions. Whether targeted therapy of this pathogen or optimization of the microbiome prevents dysplasia remains speculative.

Abstract
Purpose: Unsatisfactory collection of cells during Papanicolaou (Pap) tests prevents the detection of cervical cancer and dysplasia. Prior research found that trans masculine (TM) individuals are significantly more likely than cisgender women to have an unsatisfactory Pap test. The purpose of this study was to identify factors that place some TM individuals at greater risk for an unsatisfactory Pap test than others. Methods: Between 2015 and 2016, 150 TM adults were enrolled in a cross-sectional survey assessing demographics, health characteristics, health care experiences, trauma history, and unsatisfactory Pap test history. Bivariate and multivariable logistic regression analyses conducted in 2020 examined associations between age, length of time on testosterone, smoking history, having to educate a provider about transgender people to receive appropriate care, anticipated health care stigma, post-traumatic stress disorder (PTSD) symptoms, and lifetime history of unsatisfactory Pap tests. Results: Of all participants, 20.2% had an unsatisfactory test in their lifetime, age ranged from 21 to 50 years, 55.1% used testosterone for 1 year or more, and 41.3% had PTSD symptoms. In the multivariable model, older age (adjusted odds ratio [AOR] = 1.15; 95% confidence interval (CI) = 1.04-1.27; p < 0.01), 1 year or more lifetime testosterone use (AOR = 3.51; 95% CI = 1.02-12.08; p = 0.046), and PTSD symptoms (AOR = 3.48; 95% CI = 1.10-11.00, p = 0.03) were significantly associated with increased odds of having an unsatisfactory Pap test. Conclusions: Older age, testosterone use, and PTSD symptoms are associated with lifetime unsatisfactory Pap tests among TM adults. Clinicians should assess TM patients' trauma and testosterone use history before Pap tests and utilize trauma-informed practices that facilitate the collection of adequate Pap samples.

Abstract
INTRODUCTION The 2020 American Cancer Society guidelines preferred primary human papillomavirus (HPV) screening for cervical cancer prevention. Studies investigating the role of cytology in detection of cervical precancer/cancer have focused on high-grade squamous intraepithelial lesion (HSIL) or worse interpretations. Here, we have examined the significance of all those cytology results that require histologic follow-up as per the current management guidelines, regardless of the HPV test result. MATERIALS AND METHODS A database search (September 2010 to December 2019) retrieved cervical Papanicolaou tests with any of the following interpretations: ≥ atypical squamous cells - cannot exclude HSIL or low-grade squamous intraepithelial lesion, HSIL cannot be excluded, and ≥ atypical glandular cells, not otherwise specified and its subcategories. Of these, those with concurrent negative HPV test result were included for further analysis. For this cohort, relevant clinical history and histologic follow-up (within 1 year) were recorded. RESULTS The study cohort comprised 763 patients. Of them, 586 (76.8%) patients had histologic follow-up: 53 (9.0%) had ≥ HSIL/adenocarcinoma in situ; of which, 43 (81.1%) had prior abnormal cytology/histology/not otherwise specified history and/or HPV positivity, and 66 (11.3%) had HPV-unassociated neoplasia; of which, 60 (90.9%) had a known diagnosis or clinical signs/symptoms of the disease. CONCLUSION With widespread adoption of risk-based approach to management, the role of cytology, by itself, will likely diminish in the detection of HPV-associated lesions. Additional data regarding the role of cytology in the screening of patients with no/unknown/limited history and in the detection/management of HPV-independent lesions may be helpful for designing future screening guidelines.

Abstract
HPV testing in cervical cancer screening programs offers the possibility of introducing molecular standardized biomarkers for the triage of HPV-positive women. This study aimed to evaluate the role of HPV genotyping and viral load as possible diagnostic biomarkers of high-grade cervical lesions (CIN2+) by performing a preliminary evaluation of a new HPV test. Cervical specimens were obtained from 200 women referred for a colposcopy. Samples were tested using both Anyplex™ II HR-HPV as well as OncoPredict HPV® Screening (SCR) and quantitative typing (QT). Using a cycle threshold cutoff (Ct) of 36.8 for the SCR assay and 1.27 log10 (viral copies/104 cells) for the QT assay, relative clinical sensitivity for CIN2+ and relative clinical specificity for CIN2- as compared to Anyplex™ II HR-HPV were, respectively, 0.92 and 1.00 for SCR and 1.35 and 1.24 for QT. The distribution of high-risk HPV (HR-HPV) genotypes (p = 0.009) as well as the viral copy numbers (CIN2-: 3.7 log10 (viral copies/104 human cells); CIN2+: 4.3 log10 (viral copies/104 human cells); p = 0.047) were found to differ in women with high- and low-grade cervical lesions, suggesting a possible role of HPV genotyping and normalized viral load as potential biomarkers to identify women at increased risk of cervical lesions.

Abstract
Viruses are the most abundant and genetically diverse entities on the planet, infect all life forms and have evolved with their hosts. To date, 263 viral species have been identified that infect humans, of which only seven are considered type I oncogenic. Human papillomavirus (HPV) is the main virus associated with cancer and is responsible for practically all cases of cervical carcinoma. Screening tests for early detection have been available since the 1960s. Undoubtedly, the entailment between knowledge of HPV biology and the natural history of cervical cancer has contributed to the significant advances that have been made for its prevention since the 21st century, with the development of prophylactic vaccines and improved screening strategies. Therefore, it is possible to eradicate invasive cervical cancer as a worldwide public health problem, as proposed by the WHO with the 90-70-90 initiative based on vaccination coverage, screening, and treatment, respectively. In addition, the emerging knowledge of viral biology generates opportunities that will contribute to strengthening prevention and treatment strategies in HPV-associated neoplasms.

Abstract
Background Replacement of cytology screening with HPV testing is recommended and essential for cervical cancer elimination. HPV testing for primary screening was implemented in 12 laboratories within 9 Latin American countries, as part of the ESTAMPA cervical cancer screening study. Our observations provide information on critical operational aspects for HPV testing implementation in diverse resource settings. Methods We describe the implementation process of HPV testing in ESTAMPA, focusing on laboratory aspects. We assess the readiness of 12 laboratories to start HPV testing and their continuity capacity to maintain good quality HPV testing until end of recruitment or up to December 2021. Readiness was based on a checklist. Information from the study database; regular meetings and monitoring visits; and a questionnaire on laboratory operational aspects sent in May 2020 were used to assess continuity capacity. Compliance with seven basic requirements (readiness) and eight continuity requirements (continuity capacity) was scored (1 = compliant, 0 = not compliant) and totaled to classify readiness and continuity capacity as very limited, limited, moderate or high. Experiences, challenges, and enablers of the implementation process are also described. Results Seven of 12 laboratories had high readiness, three moderate readiness, and of two laboratories new to HPV testing, one had limited readiness and the other very limited readiness. Two of seven laboratories with high readiness also showed high continuity capacity, one moderate continuity capacity, and the other four showed limited continuity capacity since they could not maintain good quality HPV testing over time. Among three laboratories with moderate readiness, one kept moderate continuity capacity and two reached high continuity capacity. The two laboratories new to HPV testing achieved high continuity capacity. Based on gained expertise, five laboratories have become part of national screening programs. Conclusion High readiness of laboratories is an essential part of effective implementation of HPV testing. However, high readiness is insufficient to guarantee HPV testing high continuity capacity, for which a "culture of quality" should be established with regular training, robust monitoring and quality assurance systems tailored to local context. All efforts to strengthen HPV laboratories are valuable and crucial to guarantee effective implementation of HPV-based cervical screening.

Abstract
Background Cervical screening is transitioning from primary cytology to primary human papillomavirus (HPV) testing. HPV testing is highly sensitive but there is currently no high-specificity triage method for colposcopy referral to detect cervical intraepithelial neoplasia grade 3 or above (CIN3+) in women positive for high-risk (hr) HPV subtypes. An objective, automatable test that could accurately perform triage, independently of sample heterogeneity and age, is urgently required. Methods We analyzed DNA methylation at ~850,000 CpG sites across the genome in a total of 1254 cervical liquid-based cytology (LBC) samples from cases of screen-detected histologically verified CIN1-3+ (98% hrHPV-positive) and population-based control women free from any cervical disease (100% hrHPV-positive). Samples were provided by a state-of-the-art population-based cohort biobank and consisted of (i) a discovery set of 170 CIN3+ cases and 202 hrHPV-positive/cytology-negative controls; (ii) a diagnostic validation set of 87 CIN3+, 90 CIN2, 166 CIN1, and 111 hrHPV-positive/cytology-negative controls; and (iii) a predictive validation set of 428 cytology-negative samples (418 hrHPV-positive) of which 210 were diagnosed with CIN3+ in the upcoming 1–4 years and 218 remained disease-free. Results We developed the WID-CIN (Women’s cancer risk IDentification-Cervical Intraepithelial Neoplasia) test, a DNA methylation signature consisting of 5000 CpG sites. The receiver operating characteristic area under the curve (AUC) in the independent diagnostic validation set was 0.92 (95% CI 0.88–0.96). At 75% specificity (≤CIN1), the overall sensitivity to detect CIN3+ is 89.7% (83.3–96.1) in all and 92.7% (85.9–99.6) and 65.6% (49.2–82.1) in women aged ≥30 and <30. In hrHPV-positive/cytology-negative samples in the predictive validation set, the WID-CIN detected 54.8% (48.0–61.5) cases developing 1–4 years after sample donation in all ages or 56.9% (47.6–66.2) and 53.5% (43.7–63.2) in ≥30 and <30-year-old women, at a specificity of 75%. Conclusions The WID-CIN test identifies the vast majority of hrHPV-positive women with current CIN3+ lesions. In the absence of cytologic abnormalities, a positive WID-CIN test result is likely to indicate a significantly increased risk of developing CIN3+ in the near future.

Abstract
We evaluated how temporary disruptions to primary cervical cancer (CC) screening services may differentially impact women due to heterogeneity in their screening history and test modality. We used three CC models to project the short- and long-term health impacts assuming an underlying primary screening frequency (i.e., 1, 3, 5, or 10 yearly) under three alternative COVID-19-related screening disruption scenarios (i.e., 1-, 2-, or 5-year delay) versus no delay in the context of both cytology-based and human papillomavirus (HPV)-based screening. Models projected a relative increase in symptomatically detected cancer cases during a 1-year delay period that was 38% higher (Policy1-Cervix), 80% higher (Harvard), and 170% higher (MISCAN-Cervix) for underscreened women whose last cytology screen was 5 years prior to the disruption period compared with guidelines-compliant women (i.e., last screen 3 years prior to disruption). Over a woman's lifetime, temporary COVID-19-related delays had less impact on lifetime risk of developing CC than screening frequency and test modality; however, CC risks increased disproportionately the longer time had elapsed since a woman's last screen at the time of the disruption. Excess risks for a given delay period were generally lower for HPV-based screeners than for cytology-based screeners. Our independent models predicted that the main drivers of CC risk were screening frequency and screening modality, and the overall impact of disruptions from the pandemic on CC outcomes may be small. However, screening disruptions disproportionately affect underscreened women, underpinning the importance of reaching such women as a critical area of focus, regardless of temporary disruptions.

Abstract
OBJECTIVE Women living with HIV (WLWH) have increased risk of human papillomavirus (HPV) infection, precancers, and invasive cervical cancers. This study aims to determine the rate of cervical cytologic progression and related factors in minority WLWH across 5 years. MATERIALS AND METHODS We used our HIV clinic database, complemented with a retrospective chart review to identify WLWH with a baseline negative cervical cytology between 2009 and 2012 and 5-year follow-up. Data included race/ethnicity, age, years living with HIV, AIDS status, viral load, history of smoking, drug use, and HPV status. Multivariate logistic regression tested progression of negative cytology to low-grade/high-grade squamous intraepithelial lesions (LGSIL/HGSIL). RESULTS Among 162 WLWH, 42% were African American, 30% non-Hispanic African Caribbean, and 26% Hispanic. At baseline, 21% had detectable viral load (>200 cp/mL), mean age was 44.8 (±11 years), and mean years living with HIV was 9.6 (±6.9). After 5 years, 19% of the cohort progressed to LGSIL/HGSIL. Human papillomavirus was detected consistently among women with cytologic changes (30% vs 7%, p < .01). Significant factors that predicted higher likelihood of progression to LGSIL/HGSIL were detection of HPV (adjusted odds ratios = 5.11 [1.31-19.93]; p = .02), and Centers for Disease Control and Prevention-defined AIDS status (adjusted odds ratios = 4.28 [1.04-17.63]; p = .04). Of the women who maintained negative cytology at 1 to 2 years (n = 102), 5 women (5%) progressed during the following 3 years before the recommended follow-up. CONCLUSIONS Human papillomavirus detection and AIDS status were significant factors predicting progression to LGSIL/HGSIL among minority WLWH. Providers screening WLWH for cervical intraepithelial neoplasia should carefully decide screening intervals for minority populations.

Abstract
BACKGROUND Cervical cancer screening programs are facing a programmatic shift where screening protocol based on human papillomavirus testing (HPV-Screening protocol) is replacing the liquid-based cytology (LBC-Screening protocol). For safe technology transfer within the nationwide screening programme in Norway, HPV-Screening protocol was implemented randomized to compare the real-world effectiveness of HPV-Screening protocol and LBC-Screening protocol at the first screening round. METHODS Among 302,295 women ages 34 to 69 years scheduled to attend screening from February 2015 to June 2017, 157,447 attended. A total of 77,207 were randomly allocated to the HPV-Screening protocol and 80,240 were allocated to the LBC-Screening protocol. All women were followed up for 18 months. RESULTS The HPV-Screening protocol resulted in a relative increase of 60% in the detection of cervical intraepithelial neoplasia (CIN) grade 2 or worse [risk ratio (RR) = 1.6, 95% confidence interval (CI) = 1.5-1.7], 40% in CIN grade 3 or worse (RR = 1.4, 95% CI = 1.3-1.6), 40% in cancer (RR = 1.4, 95% CI = 1.0-2.1), and 60% in colposcopy referrals (RR = 1.6, 95% CI = 1.5-1.6) compared with LBC-Screening. The performance of both protocols was age dependent, being more effective in women ages under 50 years. CONCLUSIONS The HPV-Screening protocol was well accepted by women in Norway and detected more CIN2, CIN3, and cancers compared with the LBC-Screening protocol. IMPACT A randomized implementation of the HPV-Screening protocol with real-world assessment enabled a gradual, quality assured, and safe technology transition. HPV-based screening protocol may further be improved by using HPV genotyping and age-specific referral algorithms.

Abstract
OBJECTIVE Primary HPV screening programmes for cervical cancer have been implemented in many European countries using a cytology triage. Nonetheless, the optimal cytology triage strategy for minimizing the harms and maximizing the benefits is yet unclear. We identified key characteristics of different algorithms for HPV screening with cytology triage. METHODS Using the Finnish randomized HPV screening trial data, we formulated five post-hoc algorithms for HPV screening with a cytology triage, one for HPV screening without a triage and one for cytology screening. Sensitivity, specificity, positive predictive value, colposcopy referral rate and cumulative sensitivity for CIN II + s detected during the first and second screening rounds of the trial were calculated for all algorithms. RESULTS In the first screening round, direct referral of HPV positives to colposcopy led to the highest sensitivity (94%) accompanied by the lowest specificity (93%). Following HPV positives up with one repeat screen showed 86% sensitivity and 97% specificity. The corresponding figures with two repeat screens were 84% and 98%. In HPV algorithms, where cytology negative HPV positive individuals had no follow-up, the sensitivities were 65-82% and the specificities 98-99%. The Cytology algorithm had a low sensitivity (69%) with a high specificity (99%). Compared to the first round, the second-round sensitivities were lower and specificities similar or higher. CONCLUSIONS The best balance between sensitivity and specificity was achieved by an HPV algorithm with two repeated follow-up tests. However, all HPV algorithms with cytology triage increased colposcopy volume more than the cytology algorithm and thus provoked overdiagnosis.

Abstract
BACKGROUND We evaluated the longitudinal performance of three options: HPV16/18 genotyping (HPV16/18), cytology (LBC), and p16/Ki-67 dual stain cytology (DS) for the triage of high-risk Human Papillomavirus-positive (Hr-HPV+) women within the cervical screening program in Scotland. METHODS Data were derived from a cohort of Hr-HPV+ women (n = 385) who participated in PaVDaG (Papillomavirus Dumfries and Galloway) study. Performance of triage strategies for detecting high-grade disease was assessed at 3 (in women <50 years) or 5 years (in women >50 years). Sensitivity, specificity, PPV, and cNPV of each triage test were calculated for CIN2+ and CIN3+ when used singly or sequentially. RESULTS The sensitivity of LBC (≥ borderline), DS, and HPV 16/18 genotyping for the detection of CIN2+ was 62.7% (50.7-73.3), 77.7% (63.1-83.7), and 62.7% (50.7-73.3) with corresponding cNPVs of 10.9%, 8.4%, and 11.9%. The option with the highest sensitivity and lowest cNPV was HPV 16/18 genotyping followed by LBC of Hr-HPV other+ and then DS of the LBC negatives. This yielded sensitivity of 94.7% (86.2-98.3) and cNPV 2.7% for CIN2+. Triage performance was similar if women had tested Hr-HPV+ positive by vaginal self-sampling. CONCLUSIONS Two-step triage with HPV 16/18 genotyping before LBC (or DS) for Hr-HPV other+ women was associated with a lower risk of significant disease at follow-up compared with single triage approaches. IMPACT This study provides longitudinal performance data on triage strategies in Hr-HPV+ women and will be informative for the evolution of cervical screening programs that increasingly rely on molecular technologies.

Abstract
Cervical cancer is estimated to cause 341,831 deaths each year, with 9 of 10 deaths occurring in developing countries. Over the past decade, there has been a significant increase in cervical cancer incidence among women in the Philippines. Persistent infection with high-risk human papillomavirus (HPV) is the well-established necessary cause of cervical cancer. Based on limited studies conducted in the Philippines, the prevalence of infection with any HPV genotype was 93.8% for cervical squamous cell carcinoma and 90.9% for cervical adenocarcinomas. HPV types 16 and 18 were the most common HPV genotypes among Filipino patients with cervical cancer. On the other hand, the incidence of HPV infection among Filipino women with normal cervices was 9.2%. The World Health Organization has launched a global agenda of eliminating HPV infection by 2030. One of its key milestones is to vaccinate 90% of girls with the HPV vaccine by 15 years. However, the HPV vaccination rate among Filipino women remains to be unsatisfactory. HPV vaccination has only been included in the Philippine Department of Health's community-based National Immunization Program in 2015. Despite these efforts, the Philippines currently ranks last on HPV program coverage among low-middle income countries, with coverage of only 23% of the target female population for the first dose and 5% for the final dose. The principal reason for the non-acceptance of HPV vaccines was the perceived high cost of vaccination. The low utilization of available cervical cancer screening tests such as Pap smear and visual inspection with acetic acid hampered the Philippines' control and prevention of HPV infection and cervical cancer. Among those diagnosed with cervical cancer in the Philippines, only an estimated 50% to 60% receive some form of treatment. To this end, we summarize the burden of HPV infection and cervical cancer on Filipinos and the risk factors associated with the disease. We present the current screening, diagnostics, treatment, and prevention of HPV-related diseases in the Philippines. Lastly, we also propose solutions on how each building block in health systems can be improved to eliminate HPV infection and reduce the burden of cervical cancer in the Philippines.

Abstract
In addition to liquid-based cytology (LBC) and HR HPV testing, p16/ki-67 dual-staining is another method for cervical cancer screening. The combination of any two methods can improve the accuracy of screening, but some cervical lesions are still missed or misdiagnosed. In this retrospective study, the significance of LBC, HR HPV testing and especially p16/ki-67 dual-staining in cervical lesion screening was evaluated with reference to histological diagnosis. At the same time, we tried to explore the value of p16/ki-67 dual-staining combined with LBC and HR HPV testing (triple detection) in improving the diagnostic specificity of CIN2+ and reducing the missed diagnosis of CIN2+ lesions. We found that p16/ki-67 dual-staining was valuable in identifying cervical CIN2+ lesions and reducing the missed diagnosis of CIN2+ in HPV negative patients. More than 96% of CIN2+ patients were positive for two or three tests of triple detection. Whole positive triple detection can effectively predict high grade cervical lesions. In conclusion, the triple detection can distinguish almost all cervical CIN2+ lesions. Our data put forward and highlight the feasibility and significance of triple detection in cervical lesion screening.

Abstract
OBJECTIVES To provide updated evidence about the risk of cervical intraepithelial neoplasia grade 3 or higher (CIN3+) and cervical cancer after a negative human papillomavirus (HPV) test in primary cervical screening, by age group and test assay. DESIGN Observational study. SETTING Real world data from the English HPV screening pilot's first and second rounds (2013-16, follow-up to end of 2019). PARTICIPANTS 1 341 584 women. INTERVENTIONS Cervical screening with HPV testing or liquid based cytological testing (cytology or smear tests). Women screened with cytology were referred to colposcopy after high grade cytological abnormalities or after borderline or low grade abnormalities combined with a positive HPV triage test. Women screened with HPV testing who were positive were referred at baseline if their cytology triage test showed at least borderline abnormalities or after a retest (early recall) at 12 and 24 months if they had persistent abnormalities. MAIN OUTCOME MEASURES Detection of CIN3+ and cervical cancer after a negative HPV test. RESULTS For women younger than 50 years, second round detection of CIN3+ in this study was significantly lower after a negative HPV screen in the first round than after cytology testing (1.21/1000 v 4.52/1000 women screened, adjusted odds ratio 0.26, 95% confidence interval 0.23 to 0.30), as was the risk of interval cervical cancer (1.31/100 000 v 2.90/100 000 woman years, adjusted hazard ratio 0.44, 0.23 to 0.84). Risk of an incident CIN3+ detected at the second screening round in the pilot five years after a negative HPV test was even lower in women older than 50 years, than in three years in women younger than 50 years (0.57/1000 v 1.21/1000 women screened, adjusted odds ratio 0.46, 0.27 to 0.79). Women with negative HPV tests at early recall after a positive HPV screening test without cytological abnormalities had a higher detection rate of CIN3+ at the second routine recall than women who initially tested HPV negative (5.39/1000 v 1.21/1000 women screened, adjusted odds ratio 3.27, 95% confidence interval 2.21 to 4.84). Detection after a negative result on a clinically validated APTIMA mRNA HPV test was similar to that after clinically validated cobas and RealTime DNA tests (for CIN3+ at the second round 1.32/1000 v 1.14/1000 women screened, adjusted odds ratio 1.05, 0.73 to 1.50). CONCLUSIONS These data support an extension of the screening intervals, regardless of the test assay used: to five years after a negative HPV test in women aged 25-49 years, and even longer for women aged 50 years and older. The screening interval for HPV positive women who have negative HPV tests at early recall should be kept at three years.

Abstract
As the primary screening test, E6/E7 mRNA has shown similar sensitivity for CIN3+ and lower positivity rate than the HPV DNA test. Nevertheless, the overall mRNA positivity is too high for immediate colposcopy, making a triage test necessary. The aim was to estimate the mRNA performance as a primary test with different triage strategies. All HPV DNA-positives were tested for mRNA, cytology and p16/ki67. A sample of HPV DNA-negatives were also tested for mRNA to estimate test specificity. We included all CIN3+ histologically diagnosed within 24 months since recruitment. Of the 41127 participants, 7.7% were HPV DNA-positive, of which 66.4% were mRNA-positive. Among the HPV DNA-negatives, 10/1108 (0.9%) were mRNA-positive. Overall, 97 CIN3+ were found. If mRNA was used as the primary test, it would miss about 3% of all CIN3+ with a 22% reduction of positivity compared to HPV DNA. The weighted specificity estimate for <CIN2 was 94.5% (95% CI=93.9%-94.9%) and sensitivity for CIN3+ was 96.9% (95% CI=91.3%-99.1%). If all the weighted estimated 6.0% mRNA-positive women had been referred to colposcopy, PPV for CIN3+ would have been 4.2%. Cytology or p16/ki67 triage would decrease immediate referral to 1.7% and 2.0%, increasing PPV to 11.2% and 11.7%, respectively; total colposcopy referral would be 4.0% and 3.9%, respectively. As the primary screening test, the mRNA assay showed a positivity rate lower than that of HPV DNA, with a small number of CIN3+ missed. Triage with cytology or p16/ki67 would only marginally decrease overall colposcopy referral.

HPV-based screening at extended intervals missed fewer cervical precancers than cytology in the HPV FOr CervicAL Cancer (HPV FOCAL) trial. Int J Cancer 2022; 151:897-905.

Abstract
While cervix screening using cytology is recommended at 2-3-year intervals, given the increased sensitivity of human papillomavirus (HPV)-based screening to detect precancer, HPV-based screening is recommended every 4-5-year. As organized cervix screening programs transition from cytology to HPV-based screening with extended intervals, there is some concern that cancers will be missed between screens. Participants in HPV FOr CervicAL Cancer (HPV FOCAL) trial received cytology (Cytology Arm) at 24-month intervals or HPV-based screening (HPV Arm) at 48-month intervals, and co-testing (cytology and HPV testing) at exit. We investigated the results of the co-test to identify participants with cervical intraepithelial neoplasia grade 2 or higher (CIN2+) who would not have had their precancer detected if they had only their arm's respective primary screen. In the Cytology Arm, 25/62 (40.3%) identified CIN2+s were missed by primary screen (i.e., normal cytology/positive HPV test) and all 25 had normal cytology at the prior 24-month screen. In the HPV arm, three CIN2+s (3/49, 6.1%) were missed by primary screen (i.e., negative HPV test/abnormal cytology). One of these three misses had low-grade cytology findings and would also not have been referred to colposcopy outside of the trial. Multiple rounds of cytology did not detect some precancerous lesions detected with one round of HPV-based screening. In our population, cytology missed more CIN2+, even at shorter screening intervals, than HPV-based screening. This assuages concerns about missed detection post-implementation of an extended interval HPV-based screening program. We recommend that policymakers consider a shift from cytology to HPV-based cervix screening. This article is protected by copyright. All rights reserved.

Abstract
PURPOSE High-risk human papillomavirus (HR-HPV)-positive but cytology-negative cervical cancer screening results are not uncommon. This study aimed to investigate colposcopy's accuracy and diagnostic value in patients with cytology-negative HR-HPV-positive screening results. METHODS This retrospective study included patients with HR-HPV-positive cytology-negative screening results who underwent electronic colposcopy with acetic acid and multi-point cervical biopsy, HPV typing (24 HPV subtypes), and quantitative HPV detection. RESULTS Among 229 patients, 130 had chronic cervicitis, and 99 had cervical lesions (CIN1, n = 37; CIN2/3, n = 55; invasive carcinoma, n = 7). Using colposcopy as a reference, the cervical cytology false-negative rate was 43.2% (99/229). Colposcopy was more accurate in patients with HR-HPV16/18 or high viral loads. Multivariable analyses showed HPV viral load and childbearing history were the independent factors affecting the accuracy of colposcopy (P < 0.05). CONCLUSION Colposcopy in HR-HPV-positive cytology-negative patients has a moderate diagnostic accuracy. The type of cervical transformation zone and HPV viral load are independent factors affecting the accuracy of colposcopy-based diagnosis.

Abstract
Background Human papilloma virus (HPV) causes the most common sexually-transmitted infection especially among sexually-active individuals. The aim of study was to characterize the molecular characterization of HPV genotypes between 5176 female and male patients. Methods HPV DNA was extracted from genital swabs of the study participants and amplified by Real Time Polymerase Chain Reaction (PCR). Genotyping was performed for 2525 cases using REALQUALITY RQ-Multi HPV Detection Kit for the identification of 14 high risk (HR) and 2 low risk (LR) HPV genotypes. Demographic figures were analyzed in correlation with virological data statistically. Results Out of 5176 cases from 7 laboratories, 2727 (53%) were positive for HPV, of which. 2372(87%) women and 355 (13%) men were HPV positive. However, in an intra-gender analysis, positive rate was higher in men (355/637, 55.7%) than in women (2372/4539, 52%; P value 0.007). HPV positive patients were younger than negative individuals. Positive rate was higher among age categories 20–40. Genotyping was performed for 2525 cases. Out of 1219 (48%) patients who contained single genotypes, 566 (22%) and 653 (26%) harboured HR and LR genotypes, respectively. In females and males, 1189 (54%) and 117 (37%) contained multiple genotypes. No substantial associations were found between different age categories and HR/LR and multiple genotypes distribution. Conclusion The prevalence of HPV infection in both genders was high. However, men had a higher rate of infection. These observations highlighted the necessity for a plan for targeted education to younger population in the society as well as application of infection control measures against HPV infection, especially in terms of general population mass HPV vaccination.

Abstract
Introduction. Delayed implementation of evidence-driven
interventions has consequences that can be formally evaluated. In Norway,
programs to prevent cervical cancer (CC)—screening and treatment of precancerous
lesions and prophylactic vaccination against human papillomavirus (HPV)
infection—have been implemented, but each encountered delays in policy
implementation. To examine the effect of these delays, we project the outcomes
that would have been achieved with timely implementation of two policy changes
compared with the de facto delays in implementation (in Norway).
Methods. We used a multimodeling approach that combined HPV
transmission and cervical carcinogenesis to estimate the health outcomes and
timeline for CC elimination associated with the implementation of two CC
prevention policy decisions: a multicohort vaccination program of women up to
age 26 years with bivalent vaccine in 2009 compared with actual “delayed”
implementation in 2016, and a switch from cytology to primary HPV-based testing
in 2015 compared with “delayed” rollout in 2020. Results. Timely
implementation of two policy changes compared with current Norwegian prevention
policy timeline could have averted approximately 970 additional cases (range of
top 10 sets: 830–1060) and accelerated the CC elimination timeline by around 4
years (from 2039 to 2035). Conclusions. If delaying implementation
of effective and cost-effective interventions is being considered, the
decision-making process should include quantitative analyses on the effects of
delays.

Abstract
The assessment of human papillomavirus (HPV) genotype dynamics could support the adoption of more tailored preventive actions against cervical cancer. The aim of the study was to describe the prevalence of HPV infection, HPV genotype distribution, and the epidemiological characteristics of women with ASC-US cytology since the introduction of HPV-DNA testing in Sardinia (Italy), (March 2016–December 2020). Specimens were tested by RT-PCR for 14 high-risk HPV genotypes. A total of 1186 patients were enrolled, with a median (IQR) age of 41 (38–48) years. Of these women, 48.1% were positive for at least one HPV genotype; 311 (26.2%) women were vaccinated with a median (IQR) age of 38 (30/47) years. The percentage of prevalence of HPV-16, -31, -66, -56, and -51 was 36.3%, 18.7%, 11.9%, 11.4% and 10.7%, respectively. The highest prevalence of infection was found in women aged <41 years, and single women. Moreover, women aged >41 years (OR: 0.51, 95% CI: 0.31–0.86; p-value: 0.01), having parity (OR: 0.57, 95% CI: 0.34–0.96, p-value: 0.04), and higher educational level (OR: 0.39, 95% CI: 0.18–0.87; p-value: 0.02) were associated with a lower CIN2+ risk. We did not find a significant difference in terms of prevalence of HPV-16 infection between vaccinated and non-vaccinated (18.3% vs. 17.1%; p-value < 0.001). Our results support the adoption of nonavalent HPV-vaccine to prevent the most prevalent infections caused by HPV-16 and -31 genotypes and underscore the need of surveillance to implement tailored vaccination programs and preventive strategies.

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
Human papillomavirus (HPV) infections cause more than 35,900 cancers annually in the United States. Although cervical cancer is the most prevalent HPV-related malignancy in women, the virus is also responsible for a significant percentage of anal, vaginal, and vulvar cancers. A comprehensive approach to mitigating cervical cancer includes HPV vaccination (primary prevention), screening and treatment of precancerous lesions (secondary prevention), and diagnosis and treatment of invasive cancer (tertiary prevention). Although a successful strategy, there are opportunities to innovate and increase access that can also be adapted to address the unique clinical care gaps that exist with the other anogenital cancers. The Society for Women's Health Research held a series of interdisciplinary meetings and events, during which expert researchers, clinicians, patient advocates, and health care policy leaders evaluated the current landscape of HPV-related cancers and their effects on women's health. This report summarizes the discussions of this working group and areas it identified in which to address gaps in primary and secondary prevention approaches to improve access and health outcomes for women with HPV-related anogenital cancers.

Abstract
Creating effective programs for cervical cancer prevention is essential to avoid premature deaths from cervical cancer. The Dominican Republic has persistently high rates of cervical cancer, despite the availability of Pap smear screening. This study explored Dominican provider attitudes towards human papillomavirus (HPV) testing and current challenges to effective cervical cancer prevention. In this Consolidated Framework for Implementation Research (CFIR)-driven mixed methods study, we conducted in-depth interviews (N = 21) and surveys (N = 202) with Dominican providers in Santo Domingo and Monte Plata provinces regarding their perspectives on barriers to cervical cancer prevention and their knowledge and attitudes towards HPV testing as an alternative to Pap smear. Providers believed the main barrier to cervical cancer prevention was lack of cervical cancer awareness and resulting inadequate population screening coverage. Providers felt that Pap smear was widely available to women in the Dominican Republic and were unsure how a change to HPV testing for screening would address gaps in current cervical cancer screening programs. A subset of providers felt HPV testing offered important advantages for early detection of cervical cancer and were in favor of more widespread use. Cost of the HPV test and target age for screening with HPV testing were the main barriers to acceptability. Providers had limited knowledge of HPV testing as a screening test. The group was divided in terms of the potential impact of a change in screening test in addressing barriers to cervical cancer prevention in the Dominican Republic. Findings may inform interventions to disseminate global evidence-based recommendations for cervical cancer screening.

Abstract
BACKGROUND Cervical cancer screening with high-risk HPV (HrHPV) testing is being introduced. Most HrHPV infections are transient, requiring triage tests to identify individuals at highest risk for progression to cervical cancer. Head-to-head comparisons of available strategies for screening and triage are needed. Endometrial and ovarian cancers could be amenable to similar testing. METHODS Between 2016-2021 discard cervical cancer screening specimens from women ages 25-65 undergoing screening at Kaiser Permanente Northern California were collected. Specimens were aliquoted, stabilized, and stored frozen. HPV, cytology and histopathology results as well as demographic and co-factor information were obtained from electronic medical records. Follow-up collection of specimens was conducted for 2 years and EMR-based data collection was planned five years. RESULTS Collection of enrollment and follow-up specimens are complet and EMR-based follow-up data collection is ongoing. At baseline, specimens were collected from 54,971 HPV-positive, 10,219 HPV-negative/Pap-positive and 12,751 HPV-negative/Pap-negative women. Clinical history prior to baseline was available for 72.6% of individuals, of which 53.9% were undergoing routine screening, 8.6% recently had an abnormal screen, 30.3% had previous colposcopy, and 7.2% had previous treatment. As of November 2020, 55.6% had one or more colposcopies, yielding 5,515 CIN2, 2,735 CIN3 and 147 cancer histopathology diagnoses. CONCLUSIONS This robust population-based cohort study represents all stages of cervical cancer screening, management, and post-treatment follow-up. IMPACT The IRIS study is a unique and highly relevant resource allowing for natural history studies and rigorous evaluation of candidate HrHPV screening and triage markers, while permitting studies of biomarkers associated with other gynecological cancers.

Abstract
Human papillomavirus (HPV) infection is the leading cause of cervical cancer. The Papanicolaou cytology test is the usually employed type of screening for this infection; however, its sensibility is limited. Only a small percentage of women infected with high-risk HPV develop cervical cancer with an array of genetic and epigenetic modifications. Thus, it is necessary to develop rapid, reproducible and minimally invasive technologies for screening. DNA methylation has gained attention as an alternative method for molecular diagnosis and prognosis in HPV infection. The aim of the present review was to highlight the potential of DNA methylation in cervical neoplasia screening for clinical applications. It was observed that the methylation human and viral genes was correlated with high-grade lesions and cancer. Methylation biomarkers have shown a good capacity to discriminate between high-grade lesions with a transformative potential and cervical cancer, being able to detect these modifications at an early stage. With further research, the epigenetic profiles and subtypes of the tumors could be elaborated, which would aid in therapy selection by opening avenues in personalized precision medicine. Response to therapy could also be evaluated through such methods and the accessibility of liquid biopsies would allow a constant monitoring of the patient's status without invasive sampling techniques.

Abstract
BACKGROUND Cervical cancer, a preventable disease associated with the human papillomavirus, is responsible for significant morbidity and mortality globally. Primary human papillomavirus testing is more sensitive in detecting precancerous cervical lesions than cytologic screening and can be conducted using either DNA- or RNA-based assays. Screening programs must select the most appropriate assay from several available assays for their population. It is not yet known whether these assays perform equivalently in the long term, particularly among women with a negative human papillomavirus test result. This study aims to compare long-term safety after a negative human papillomavirus test result across both DNA- and RNA-based testing assays. OBJECTIVE This study aimed to compare long-term high-grade cervical intraepithelial neoplasia (grade 2 or higher and grade 3 or higher) outcomes of 2 DNA-based assays (Digene Hybrid Capture 2 High-Risk HPV DNA Test and cobas 4800 HPV Test) and 1 messenger RNA-based assay (Aptima HPV Assay) using data from the Human Papillomavirus For Cervical Cancer Trial-DECADEl (FOCAL-DECADE) cohort, by first comparing the positive and negative rates between the assays and then investigating the cumulative incidence of cervical intraepithelial neoplasia grade 2 and higher and grade 3 or higher detection among participants in the FOCAL DECADE cohort over follow-up according to human papillomavirus testing assays. STUDY DESIGN The FOCAL Trial was a randomized controlled trial that evaluated human papillomavirus testing for primary cervical cancer screening. The FOCAL-DECADE cohort subsequently followed FOCAL Trial participants passively through the British Columbia Cervix Screening Program Database for approximately 10 years after the FOCAL Trial study exit to examine the rates of cervical intraepithelial neoplasia grade 2 or higher and grade 3 or higher. For this study, eligible participants had baseline human papillomavirus-negative results from at least 1 assay and had 1 or more cytologic screens after baseline (9509 participants for DNA-based and 3473 participants for DNA- vs RNA-based assay comparisons). We constructed cumulative incidence curves and compared the hazard ratios for cervical intraepithelial neoplasia grade 2 or higher and grade 3 or higher detection according to the assays. RESULTS Over 10 years of follow-up, the cumulative incidence of cervical intraepithelial neoplasia grade 2 or higher and grade 3 or higher did not significantly differ between the DNA-based assays (hazard ratio, 0.95; 95% confidence interval, 0.84-1.06; P=.35 and hazard ratio, 0.82; 95% confidence interval, 0.66-1.01; P=.06 for cervical intraepithelial neoplasia grade 2 or higher and cervical intraepithelial neoplasia grade 3 or higher, respectively) or between the DNA- and RNA-based assays (hazard ratio, 0.97; 95% confidence interval, 0.87-1.06; P=.48 and hazard ratio, 0.94; 95% confidence interval, 0.79-1.13; P=.52 for cervical intraepithelial neoplasia grade 2 or higher and cervical intraepithelial neoplasia grade 3 or higher, respectively). CONCLUSION Among participants who tested negative for human papillomavirus at baseline, the long-term risk of cervical intraepithelial neoplasia grade 2 or higher and grade 3 or higher did not significantly differ regardless of whether DNA- or RNA-based human papillomavirus testing assays were used. Screening program decision makers can be confident that for women who test negative for human papillomavirus, DNA- and RNA-based assays exhibit similar cervical intraepithelial neoplasia grade 2 or higher outcomes over several years.

Abstract
The World Health Organization Call to Eliminate Cervical Cancer resonates in cities like Manaus, Brazil, where the burden is among the world’s highest. Manaus has offered free cytology-based screening since 1990 and HPV immunization since 2013, but the public system is constrained by many challenges and performance is not well-defined. We obtained cervical cancer prevention activities within Manaus public health records for 2019 to evaluate immunization and screening coverage, screening by region and neighborhood, and the annual Pink October screening campaign. We estimated that among girls and boys age 14–18, 85.9% and 64.9% had 1+ doses of HPV vaccine, higher than rates for age 9–13 (73.4% and 43.3%, respectively). Of the 90,209 cytology tests performed, 24.9% were outside the target age and the remaining 72,230 corresponded to 40.1% of the target population (one-third of women age 25–64). The East zone had highest screening coverage (49.1%), highest high-grade cytology rate (2.5%) and lowest estimated cancers (38.1/100,000) compared with the South zone (32.9%, 1.8% and 48.5/100,000, respectively). Largest neighborhoods had fewer per capita screening locations, resulting in lower coverage. During October, some clinics successfully achieved higher screening volumes and high-grade cytology rates (up to 15.4%). Although we found evidence of some follow-up within 10 months post-screening for 51/70 women (72.9%) with high-grade or worse cytology, only 18 had complete work-up confirmed. Manaus has successfully initiated HPV vaccination, forecasting substantial cervical cancer reductions by 2050. With concerted efforts during campaigns, some clinics improved screening coverage and reached high-risk women. Screening campaigns in community locations in high-risk neighborhoods using self-collected HPV testing can achieve widespread coverage. Simplifying triage and treatment with fewer visits closer to communities would greatly improve follow-up and program effectiveness. Achieving WHO Cervical Cancer Elimination goals in high-burden cities will require major reforms for screening and simpler follow-up and treatment.
