Abstract
Cervical cancer (CC) screening in women comprises human papillomavirus (HPV) testing followed by cytology triage of positive cases. Drawbacks, including cytology's low reproducibility and requirement for short screening intervals, raise the need for alternative triage methods. Here we used an innovative triage technique, the WID-qCIN test, to assess the DNA methylation of human genes DPP6, RALYL and GSX1 in a real-life cohort of 28,017 women aged ≥30 years who attended CC screening in Stockholm between January and March 2017. In the analysis of all 2,377 HPV-positive samples, a combination of WID-qCIN (with a predefined threshold) and HPV16 and/or HPV18 (HPV16/18) detected 93.4% of cervical intraepithelial neoplasia grade 3 and 100% of invasive CCs. The WID-qCIN/HPV16/18 combination predicted 69.4% of incident cervical intraepithelial neoplasia grade 2 or worse compared with 18.2% predicted by cytology. Cytology or WID-qCIN/HPV16/18 triage would require 4.1 and 2.4 colposcopy referrals to detect one cervical intraepithelial neoplasia grade 2 or worse, respectively, during the 6 year period. These findings support the use of WID-qCIN/HPV16/18 as an improved triage strategy for HPV-positive women.

Abstract
To investigate age and type-specific prevalences of high-risk human papillomavirus (hrHPV) and cervical intraepithelial neoplasia (CIN) in hrHPV+ women referred to colposcopy. This is a retrospective, multicenter study. Participants were women referred to one of seven colposcopy clinics in China after testing positive for hrHPV. Patient characteristics, hrHPV genotyping, colposcopic impressions, and histological diagnoses were abstracted from electronic records. Main outcomes were age-related type-specific prevalences associated with hrHPV and CIN, and colposcopic accuracy. Among 4419 hrHPV+ women referred to colposcopy, HPV 16, 52, and 58 were the most common genotypes. HPV 16 prevalence was 39.96%, decreasing from 42.57% in the youngest group to 30.81% in the eldest group. CIN3+ prevalence was 15.00% and increased with age. As lesion severity increases, HPV16 prevalence increased while the prevalence of HPV 52 and 58 decreased. No age-based trend was identified with HPV16 prevalence among CIN2+, and HPV16-related CIN2+ was less common in women aged 60 and above (44.26%) compared to those younger than 60 years (59.61%). Colposcopy was 0.73 sensitive at detecting CIN2+ (95% confidence interval[CI]: 0.71, 0.75), with higher sensitivity (0.77) observed in HPV16+ women (95% CI: 0.74, 0.80) compared to HPV16- women (0.68, 95% CI: 0.64, 0.71). Distributions of hrHPV genotypes, CIN, and type-specific CIN in Chinese mainland hrHPV+ women referred to colposcopy were investigated for the first time. Distributions were found to be age-dependent and colposcopic performance appears related to HPV genotypes. These findings could be used to improve the management of women referred to colposcopy.

Real-world effectiveness of cytology and HPV-based screening strategy in cervical cancer screening: A cross-sectional population-based study in Chengdu, China. PLoS One 2024; 19:e0299651. [PMID: 38422039 PMCID: PMC10903839 DOI: 10.1371/journal.pone.0299651] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/04/2023] [Accepted: 02/12/2024] [Indexed: 03/02/2024] Open
Abstract
Cervical cancer poses a significant health challenge in developing countries, emphasizing the need for appropriate screening strategies to accelerate the elimination of this disease. This study summarized the results of a large-scale community-based cervical cancer screening program conducted in Chengdu, China, to understand the prevalence of HPV infection and cervical lesions in the population, and to compare the real-world effectiveness of two different screening methods implemented in the program. From January 2021 to December 2022, a total of 363,376 women aged 35-64 years in Chengdu received free screenings. Among these participants, 70.1% received cytology screening and 29.9% received HPV testing combined with 16/18 genotyping and cytology triage. Ultimately, 824 cases of high-grade lesions and cervical cancer were detected, with a total detection rate of cervical cancer and precancerous lesions of 226.8 per 100,000. The follow-up rate of patients with high-grade lesions and above was 98.9%, and the treatment rate was 86.6%. The overall high-risk HPV infection rate was 11.7%, with the HPV 16/18 infection rate of 1.4%. The rate of abnormal cytology results was 2.8%. The attendance rates for colposcopy and histopathology were 71.6% and 86.1%, respectively. By calculating the age-standardized rates to eliminate the different age composition between the two group, the HPV-based screening strategy had a higher rate of primary screening abnormalities (3.4% vs. 2.8%, P<0.001), higher attendance rates of colposcopy (76.5% vs. 68.9%, P<0.001) and histopathological diagnosis (94.1% vs. 78.0%, P<0.001), higher percentage of abnormal colposcopy results (76.0% vs. 44.0%, P<0.001), and higher detection rate of cervical precancerous lesions and cancer (393.1 per 100,000 vs. 156.4 per 100,000, P<0.001) compared to cytology screening. Our study indicates that the combination of HPV testing with 16/18 genotyping and cytology triage has demonstrated superior performance in cervical cancer screening compared to cytology alone in large-scale population.

Abstract
Background: In 2019, the CDC expanded their recommendations for human papillomavirus (HPV) vaccination beyond age 26 years to include shared clinical decision-making (SCDM) among adults aged 27-45 years ("mid-adults"). The purpose of this study was to describe HPV vaccination status among mid-adult women before the implementation of SCDM for HPV vaccination. Methods: A cross-sectional survey was conducted during 2016-2019 in Connecticut, United States, and enrolled women born in 1981 or later (birth cohorts eligible for HPV vaccination). This analysis was restricted to participants aged 27 years and older at the time of the survey. Correlates of vaccination status, sources of vaccine information, and reasons for not receiving the vaccine were examined. Results: Among 298 participants, 64.4% had not received HPV vaccine. Other than age (younger age was associated with being vaccinated), no other demographic or behavioral correlates were associated with vaccination. Compared with unvaccinated women, vaccinated women were more likely to have heard about the HPV vaccine from a doctor (odds ratio [OR] = 3.45, 95% confidence interval [CI]: 2.00-5.88) and less likely to have heard about it from television (OR = 0.23, 95% CI: 0.13-0.41). The main reasons for not being vaccinated were "vaccine not offered" (48%) and "too old" (40%). Conclusions: A majority of mid-adult women in this study were not previously vaccinated against HPV, signaling the large opportunity for SCDM with this population. This may be facilitated by ensuring health care providers and mid-adult women know about the availability and potential benefits of HPV vaccination to inform decision making.

Abstract
OBJECTIVE To investigate the infection status of high-risk human papillomavirus (HR-HPV) E6/E7 mRNA in patients with a cytological diagnosis of "atypical squamous cells of undetermined significance" (ASCUS) and to analyze the pathogenic rate of different high-risk HPV subtypes combined with biopsy pathological results to provide a more accurate basis for managing ASCUS patients. METHODS A total of 1387 patients with ASCUS and HPV E6/E7 mRNA positivity who were referred for colposcopy were retrospectively analyzed. They were divided into HPV16+, 18/45 + and other HR-HPV + groups premenopausal and postmenopausal groups. The pathological results of the biopsy were divided into the LSIL- group (including normal and low-grade squamous intraepithelial lesions) and the HSIL + group (including high-grade squamous intraepithelial lesions and higher lesions). SPSS was used for the analysis. RESULTS The age group 31-40 years had the highest level of HPV16+, and HPV18/45 + was the highest in the 41-50 years group. The detection rates of HSIL + in the HPV16+, HPV18/45+, HPV 16/18/45 + and Other HR-HPV + groups were 48.4%, 18.8%, 43.9% and 15.0%, respectively. The infection rates of HPV16/18/45 in postmenopausal and premenopausal women were 42.4% and 34.3%, respectively. In the HPV18/45 group, the incidence of HSIL + was 30.0% in postmenopausal women and 15.0% in premenopausal women (P < 0.01). In the HPV 16 + and Other HR-HPV + groups, the incidence of HSIL + in postmenopausal patients was not significantly different from that in premenopausal patients. The incidence of cervical cancer in postmenopausal patients is significantly higher than that in premenopausal patients. CONCLUSIONS Colposcopy referral or further biopsy is recommended for all ASCUS patients with HPV16/18/45E6/E7 mRNA positivity and postmenopausal patients with HR-HPVE6/E7 mRNA positivity. For premenopausal ASCUS patients with other HR-HPV E6/E7 mRNA positivity, colposcopy should be performed if possible, depending on the specific situation, to achieve early detection and diagnosis.

Abstract
In Australia's HPV-based cervical screening program, we previously showed that risk of histological high-grade abnormality at 1 year post screening decreased with age in women with oncogenic HPV. In this study, we followed 878 HPV16/18 positive women aged 55 years and over for up to 3 years post screening test, to determine the proportion with histological high-grade abnormality (HGA, incorporating high-grade squamous intraepithelial abnormality (HSIL), adenocarcinoma in situ (AIS), squamous cell carcinoma (SCC) and adenocarcinoma) and to correlate risk of HGA with liquid-based cytology result and with prior screening history. HGA was detected in 7.8% at 1 year and 10.0% at 3 years, with no significant difference (P = .136), despite the number of women with follow-up information significantly increasing from 82.9% to 91.0% (P < .0001). The proportion of HPV16/18 positive women with HGA at 3 years was highest in those with an HSIL cytology result (79.0%) and lowest in those with negative cytology (6.2%). Women with an adequate screening history had fewer HGA than such women with inadequate prior screening (6.6% vs 16.0%, P = .001) or with a history of an abnormality (6.6% vs 14.4%, P = .001). HPV16/18 infection in women over 55 years may have a different natural history from that in younger women, in whom HGA are more common after HPV16/18 detection. In HPV-based cervical screening programs, management algorithms for screen-detected abnormalities based on risk stratification should include factors such as age, screening history and index cytology result, so that women receive appropriate investigation and follow-up.

Abstract
INTRODUCTION Understanding whether human papillomavirus (HPV) may establish latency in the uterine cervix is important. A better understanding of HPV natural history is useful for clinical counseling of women attending screening and to accurately inform health prevention strategies such as screening and HPV vaccination. We evaluated the extent of latent HPV infections in older women with a history of abnormal cytology. MATERIAL AND METHODS We conducted a cross-sectional study in Aarhus, Denmark, from March 2013 through April 2015. Women were enrolled if they underwent cervical amputation or total hysterectomy because of benign disease. Prior to surgery, women completed a questionnaire and a cervical smear was collected for HPV testing and morphological assessment. For evaluation of latency (i.e., no evidence of active HPV infection, but HPV detected in the tissue), we selected women with a history of abnormal cervical cytology or histology, as these women were considered at increased risk of harboring a latent infection. Cervical tissue underwent extensive HPV testing using the SPF10-DEIA-LipA25 assay. RESULTS Of 103 women enrolled, 26 were included in this analysis. Median age was 55 years (interquartile range [IQR] 52-65), and most women were postmenopausal and parous. The median number of sexual partners over the lifetime was six (IQR 3-10), and 85% reported no recent new sexual partner. Five women (19.2%) had evidence of active infection at the time of surgery, and 19 underwent latency evaluation. Of these, a latent infection was detected in 11 (57.9%), with HPV16 being the most prevalent type (50%). Nearly 80% (n = 14) of the 18 women with a history of previous low-grade or high-grade cytology with no treatment had an active or latent HPV infection, with latent infections predominating. HPV was detected in two of the six women with a history of high-grade cytology and subsequent excisional treatment, both as latent infections. CONCLUSIONS HPV can be detected in cervical tissue specimens without any evidence of an active HPV infection, indicative of a latent, immunologically controlled infection. Modeling studies should consider including a latent state in their model when estimating the appropriate age to stop screening and when evaluating the impact of HPV vaccination.

BMC WOMENS HEALTH 2021; 21:178. [PMID: 33902553 PMCID: PMC8074415 DOI: 10.1186/s12905-021-01310-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 07/13/2020] [Accepted: 04/15/2021] [Indexed: 12/24/2022]
Abstract
Background HPV cervical cancer screening (CCS) must use validated HPV tests based on the molecular detection of either viral mRNA (Aptima HPV Assay—AHPV) or DNA. AHPV has demonstrated the same cross-sectional and longitudinal sensitivity for the detection of HSIL/CIN2+ lesions but with greater specificity than HPV-DNA tests. The study aimed to estimate the total costs of a CCS with a primary HPV test based on the detection of mRNA compared to DNA in women aged 35–65 years for the National Health System. Methods A decision-tree-based model to estimate the cost of the CCS until the first colposcopy was designed based on Spanish CCS guidelines. The total cost (€, 2019) for CCS with AHPV or DNA tests (HC2 and Cobas) was calculated, including HPV test, liquid-based cytology (LBC) and colposcopy, for a population of 7,263,529 women aged 35–65 years (assuming 70% coverage). Clinical inputs derived from a literature review were validated by a multidisciplinary expert panel. Data from head-to-head studies between different HPV tests were selected. Results The use of AHPV showed reduction of 290,541 (− 35%) and 355,913 (− 40%) LBC compared to HC2 or Cobas, respectively. Furthermore, AHPV avoided 151,699 (− 47%) colposcopies versus HC2 and 151,165 (− 47%) versus Cobas. The total cost of CCS was € 282,747,877 with AHPV, € 322,587,588 with HC2 and € 324,614,490 with Cobas. Therefore, AHPV savings € − 39,839,711 versus HC2 and € − 41,866,613 versus Cobas. Conclusions Assuming that 70% of women from 35 to 65 years attend the CCS programme, the cost of screening up to the first colposcopy using AHPV would provide cost savings of up to € 41.9 million versus DNA tests in Spain.

Benefits and potential harms of human papillomavirus (HPV)-based cervical cancer screening: A real-world comparison of HPV testing versus cytology. Acta Obstet Gynecol Scand 2021; 100:394-402. [PMID: 33566361 DOI: 10.1111/aogs.14121] [Citation(s) in RCA: 14] [Impact Index Per Article: 4.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/21/2020] [Revised: 02/03/2021] [Accepted: 02/05/2021] [Indexed: 12/25/2022]
Abstract
INTRODUCTION Human papillomavirus (HPV) testing as the primary cervical cancer screening method is implemented in several countries. We report data from the first round of a large Danish pilot implementation of HPV-based screening. Our aim was to compare colposcopy referrals, detection of high-grade cervical intraepithelial neoplasia (CIN) and cervical cancer, and positive predictive value (PPV) of colposcopy referral in HPV vs cytology-based screening. MATERIAL AND METHODS From May 2017 to October 2018, women aged 30-59 years attending cervical cancer screening in the uptake area of the Department of Pathology, Vejle Hospital, Region of Southern Denmark were screened by primary HPV testing (n = 16 067) or primary cytology (n = 23 981) depending on municipality of residence. In the HPV group, women with HPV16/18, or other high-risk HPV types and abnormal cytology, were referred to immediate colposcopy. Women with other high-risk HPV types and normal cytology were invited for repeat screening with HPV test and cytology after 12 months. From a nationwide pathology register, we obtained information on screening results and subsequent histological diagnoses during up to 2.9 years after the first screen. PPVs included diagnoses within 1 year after referral. RESULTS In the HPV group, 3.7% were referred to immediate colposcopy and 2.8% were referred at the 12-month repeat screening. The total referral to colposcopy was higher in the HPV (6.6%) than cytology group (2.1%) (age-adjusted relative referral = 3.05, 95% confidence interval [CI] 2.75-3.38). The detection of CIN3+ was higher in the HPV (1.5%) than the cytology group (0.8%) (age-adjusted relative detection = 1.88, 95% CI 1.56-2.28). The probability of CIN3+ among women referred to colposcopy (= PPV) was lower in the HPV (21.1%; 95% CI 18.7%-23.7%) than the cytology group (34.6%; 95% CI 30.7%-38.9%). In the HPV group, the PPV was lower among women referred at repeat screening (12.1%) than among women referred immediately (27.8%). CONCLUSIONS Compared with cytology-based screening, HPV-based screening provided a 90% increased CIN3+ detection at the cost of a threefold increase in colposcopy referrals, when considering complete data from the prevalence round. Our findings support implementation of HPV-based screening in Denmark, but modifications of screening algorithms may be warranted to decrease unnecessary colposcopy referrals.

A proposed new generation of evidence-based microsimulation models to inform global control of cervical cancer. Prev Med 2021; 144:106438.

Abstract
Health decision models are the only available tools designed to consider the lifetime natural history of human papillomavirus (HPV) infection and pathogenesis of cervical cancer, and the estimated long-term impact of preventive interventions. Yet health decision modeling results are often considered a lesser form of scientific evidence due to the inherent needs to rely on imperfect data and make numerous assumptions and extrapolations regarding complex processes. We propose a new health decision modeling framework that de-emphasizes cytologic-colposcopic-histologic diagnoses due to their subjectivity and lack of reproducibility, relying instead on HPV type and duration of infection as the major determinants of subsequent transition probabilities. We posit that the new model health states (normal, carcinogenic HPV infection, precancer, cancer) and corollary transitions are universal, but that the probabilities of transitioning between states may vary by population. Evidence for this variability in host response to HPV infections can be inferred from HPV prevalence patterns in different regions across the lifespan, and might be linked to different average population levels of immunologic control of HPV infections. By prioritizing direct estimation of model transition probabilities from longitudinal data (and limiting reliance on model-fitting techniques that may propagate error when applied to multiple transitions), we aim to reduce the number of assumptions for greater transparency and reliability. We propose this new microsimulation model for critique and discussion, hoping to contribute to models that maximally inform efficient strategies towards global cervical cancer elimination.

Abstract
OBJECTIVE To compare primary test positivity in cytology and human papillomavirus-based screening between different Nordic cervical cancer screening programs using harmonized register data. METHODS This study utilized individual-level data available in national databases in Finland, Iceland, Norway, and Sweden. Cervical test data from each country were converted to standard format and aggregated by calculating the number of test episodes for every test result for each calendar year and one-year age group and test method. Test positivity was estimated as the proportion of positive test results of all primary test episodes with a valid test result for "any positive" and "clearly positive" results. RESULTS The age-adjusted rate ratio for any positive test results in primary human papillomavirus-based screening compared to cytology was 1.66 (95% CI 1.64-1.68). The age-adjusted rate ratio for clearly positive test results was 1.02 (95% CI 1.00-1.05). A decreasing rate ratio by age was seen in both any positive and clearly positive test results. Test positivity increased over time in Iceland, Norway, and Sweden but slightly decreased in Finland. CONCLUSIONS The probability of any positive test result was higher in human papillomavirus testing than in primary cytology, even though the cross-sectional detection of a clearly positive test result was the same. Human papillomavirus testing can still lead to an improved longitudinal sensitivity through a larger number of follow-up tests and the opportunity to identify women with a persistent human papillomavirus infection. Further research on histologically verified precancerous lesions is needed in primary as well as repeat testing.

Negative Roche cobas HPV testing in cases of biopsy-proven invasive cervical carcinoma, compared with Hybrid Capture 2 and liquid-based cytology. J Am Soc Cytopathol 2020; 10:128-134. [PMID: 32896510 DOI: 10.1016/j.jasc.2020.08.006] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/10/2020] [Revised: 08/04/2020] [Accepted: 08/10/2020] [Indexed: 11/24/2022]
Abstract
INTRODUCTION The objective of this study was to conduct a retrospective analysis of results of cytology and Roche cobas (RC) and Hybrid Capture 2 (HC2) human papillomavirus (HPV) screening tests in cases of biopsy-proven invasive cervical carcinoma. MATERIALS AND METHODS The clinical data were obtained at a university hospital in New York, NY, between 2004 and 2017. Results of cytology, reported per Bethesda classification system, and HPV screening in 177 identified cases with cytology and biopsy-proven diagnosis of cervical carcinoma were included in the analysis. RESULTS Two cohorts were analyzed. Of the 177 identified cases, cotesting was performed for 100 patients. Among these 100, cotesting screening results would not trigger immediate colposcopy in 6%; HPV screening results were reported as negative in 16% (16% of all RC, 16% of all HC2, 16% total) and, if HPV was the only screening modality, would not trigger a colposcopy. Of the 177 total cases, 128 patients underwent cytology screening prior to biopsy, with a cytology diagnosis that, alone, would not trigger immediate colposcopy in 14%. CONCLUSIONS The HPV DNA screening and cytology screening alone were negative for 16% and 14%, respectively, of patients with biopsy-proven diagnoses of invasive carcinoma of cervical origin, without a significant difference in failure rates between cytology, HC2, and RC. The cotesting approach had a significantly lower failure rate (6%) compared with the 2 other screening modalities alone.

Abstract
Australia's new HPV-based cervical screening program is based on an algorithm that incorporates reflex cytology to guide decisions about further follow-up with colposcopy and, if indicated, biopsy. We reviewed results for 2300 women referred directly for colposcopy after their first positive HPV screening test, to determine the proportion that had underlying histological high-grade abnormality (HGA). Overall, HGA was detected in 24.3% of women. Among HPV16/18 positive women, 18.0% had HGA, increasing from 6.6% among women with negative cytology to 79.7% among women with high-grade squamous lesion or worse, or any glandular lesion on cytology (HSIL+; P-trend < .001). For this latter group, the proportion with HGA was higher among HPV16/18 positive women than among those positive for other oncogenic types (68.8%; P = .029). Among women with ASC-H cytology, 51.8% had HGA, with no difference between HPV groups (P = .314). In analyses by age-groups, detection of HGA was highest, at 36.4%, among women younger than 35 years, then decreased significantly to 5.9%, among women aged 65 to 74 years (P-trend < .001). The relationship of decreasing HGA detection with increasing age was strong for women with negative cytology, and those with ASC-H cytology (P-trend < .001 for each). For women with HSIL+ cytology, detection of HGA was high and stable, regardless of age (P-trend = .211). This report describes the first follow-up colposcopy findings in Australia's new HPV-based cervical screening program. The results demonstrate the additional value of reflex cytology in managing HPV positive women and suggest that further refinement of the risk-based algorithm to account for age may be warranted.

Abstract
The Scale-Up project introduced vaginal self-sampling and low-cost human papillomavirus (HPV) testing as the primary approach for cervical cancer screening in selected public health centers in Guatemala, Honduras, and Nicaragua. We evaluate the country-specific accomplishments in screening: target-coverage, triage, and treatment. Between 2015 and 2018, cervical cancer screening was offered to women at least 30 years of age. Triage of HPV-positive women was based on visual inspection with acetic acid or Pap. Aggregated data included total women screened, use of self-sampling, age, time elapsed since last screening, HPV results, triage tests, triage results, and treatment. A total of 231,741 women were screened for HPV, representing 85.8% of the target populations within the project. HPV positivity was lower in Guatemala (12.4%) compared to Honduras and Nicaragua (14.5% and 14.2%, respectively, p < 0.05). A follow-up triage test was completed for 84.2%, 85.8%, and 50.1% of HPV-positive women in Guatemala, Nicaragua, and Honduras, respectively. Of those with a positive triage test, 84.7%, 67.1%, and 58.8% were treated in Guatemala, Nicaragua, and Honduras, respectively. First-time screening was highest in Nicaragua (55.8%) where self-sampling was also widely used (97.1%). The Scale-Up project demonstrated that large-scale cervical cancer screening and treatment intervention in a high-burden, low-resource setting can be achieved. Self-sampling and ablative treatment were key to the project's achievements. Data monitoring, loss to follow-up, and triage methods of screen- positive women remain critical to full success.

Abstract
Many countries are transitioning to HPV testing for cervical cancer screening, despite a lack of long-term experience. To anticipate multi-round screening performance, we analyzed 15-year HPV testing results at Kaiser Permanente Northern California (KPNC). We evaluated HPV test result patterns among women aged 30-64 undergoing triennial HPV/cytology cotesting at KPNC during 2003-2018. We calculated incidence rates and proportion of CIN3+ diagnoses associated with the most frequent HPV testing patterns overall and stratified by age. From 2003 to 2018, a total of 1,361,581 women had a valid HPV test result, and 7,087 were diagnosed with CIN3+. Incidence rates of CIN3+ after HPV positivity were lowest when HPV detection was new and highest in women with prevalent infections (770 vs. 13,910/100,000 person-years). Repeat test negativity reduced subsequent incidence rates of CIN3+ to extremely low levels (18/100,000 person-years following four consecutive negative results). For mixed patterns of positivity/negativity, the recency and frequency of positive tests were associated with increased rates of CIN3+ diagnosis. Most CIN3+ cases (76%) were diagnosed in women who were positive at baseline (the first known positive HPV result); 16% were attributed to apparent newly detected infections and 3% to possible reappearing infections. These results corroborate previous findings that current HPV positivity, particularly when prevalent rather than new, is associated with the highest rates of CIN3+. In a screening program implementing HPV testing, most CIN3+ is detected at the first HPV positive test.

Abstract
Background HPV test appears to be more effective in cervical cancer (CC) screening. However, the decision of its adoption as a primary screening method by substituting the established cytology lies in the evaluation of multiple criteria. Aim of this study is to evaluate the economic and clinical impact of HPV test as primary screening method for CC. Methods A decision tree and a Markov model were developed to simulate the screening algorithm and the natural history of CC. Fourteen different screening strategies were evaluated, for women 25–65 years old. Clinical inputs were drawn from the HERMES study and cost inputs from the official price lists. In the absence of CC treatment cost data, the respective Spanish costs were used after being converted to 2017 Greek values. One-way and probabilistic sensitivity analyses were conducted. Results All screening strategies, that offer as primary screening method triennial HPV genotyping (simultaneous or reflex) alone or as co-testing with cytology appear to be more effective than all other strategies, with regards to both annual CC mortality, due to missed disease (-10.1), and CC incidence(-7.5) versus annual cytology (current practice). Of those, the strategy with HPV test with simultaneous 16/18 genotyping is the strategy that provides savings of 1.050 million euros annually. However, when the above strategy is offered quinquennially despite the fact that outcomes are decreased it remains more effective than current practice (-7.7 deaths and -1.3 incidence) and more savings per death averted (1.323 million) or incidence reduced (7.837 million) are realized. Conclusions HPV 16/18 genotyping as a primary screening method for CC appears to be one of the most effective strategies and dominates current practice in respect to both cost and outcomes. Even when compared with all other strategies, the outcomes that it generates justify the cost that it requires, representing a good value for money alternative.

Abstract
OBJECTIVE To assess the 5-year risk of high-grade lesions in women with a transient high-risk HPV infection. DESIGN Population-based cohort study. SETTING HPV primary testing within population-based organised cervical cancer screening programmes. POPULATION Italian women enrolled in seven pilot projects and attending the second round. METHODS On the basis of the cytology triage performed on HPV-positive women, immediate colposcopy or HPV repeat at 12 months was recommended. Data were collected at the subsequent round 3-4 years after HPV infection clearance. MAIN OUTCOME MEASURES Rates of HPV infection, CIN2+ and CIN3+ detection at subsequent round after HPV clearance, and relative risks (RR) in comparison with HPV-negative women (with 95% confidence interval). RESULTS Data on 1230 women (1027 aged 25-64 years and 203 aged 35-64 years) have been analysed. Overall compliance with repeat HPV testing was 84%. In comparison with HPV-negative women, those with a transient HPV infection had higher proportions of HPV positivity (15% versus 3.7%) and of CIN2+ lesions (0.87% versus 0.23%) in round two; most of these (7/10) were CIN2; no cancers were detected, and CIN3 occurred in 3/1230 (0.24%). CONCLUSIONS HPV-based protocols for cervical cancer screening allow long intervals for HPV-negative women; it is important to monitor the clinical outcome in the women with transient high-risk HPV infection. CIN3 detection is similar to that observed in routine European cytology-based screening programmes (CIN3+: 2.7‰); 5-year intervals may provide reasonable protection but longer intervals are not recommended. TWEETABLE ABSTRACT A screening interval of 5 years (but no longer) appears safe in women with transient HPV detection.

Abstract
We studied whether triage of human papillomavirus (HPV)-positive women participating in an HPV-based screening programme can be improved by including the HPV result at the previous screen in the triage algorithm. We analyzed data of a subgroup of 366 women from the POBASCAM trial, screened by cytology and HPV cotesting. Women were included if they tested HPV-positive in the second HPV-based screening round. We evaluated the clinical performance of 16 strategies, consisting of cytology, HPV genotyping, and/or previous screen HPV result. The clinical endpoint was cervical precancer or cancer (CIN3+). The current Dutch triage testing policy for HPV-positive women is to refer women for colposcopy if they have abnormal cytology at baseline or after 6-18 months. In the second HPV-based screening round, this strategy yielded a negative predictive value (NPV) of 95.8% (95% confidence interval: 91.9-98.2) and colposcopy referral rate of 37.6% (32.3-43.2%). Replacing repeat cytology by the previous screen HPV result yielded a similar NPV (96.9%, 93.3-98.9) and colposcopy referral rate (38.8%, 33.4-44.4). A higher NPV (99.2%, 96.3-100%) at the cost of a higher colposcopy referral rate (49.2%, 43.6-54.8) was achieved when cytology was combined with HPV16/18 genotyping. The other 13 triage strategies yielded a lower NPV, a higher colposcopy referral rate or performed similarly but required additional testing. HPV-positive women in the second HPV-based screening round can be suitably managed by cytology, HPV16/18 genotyping and the HPV result at the previous screen, obviating the need for repeat testing of HPV-positive, cytology negative women.

Abstract
Current US guidelines recommend against cervical screening beyond age 65 in women who have had adequate negative screening. In anticipation of the next round of evidence review and guideline updates, we provide a critical review of the evidence supporting the exiting recommendation in the US, highlighting both practice changes and new insights into the epidemiology and natural history of HPV and cervical cancer. Current recommendations are based, by necessity, on cytology alone, and will be limited in generalizability to evolving screening strategies with co-testing and primary HPV testing. The lack of empirical data to define what constitutes 'adequate recent screening with negative results' is compounded by difficulties in predicting future risk without consideration of concepts of HPV latency and cohort effects of changing sexual behaviour in US women over time. We urge caution in extrapolating past risk experience in post-menopausal women to today's population, and suggest study designs to strengthen the evidence base in well-screened older women. We further recommend building the qualitative evidence base to better define the harms and benefits of screening among older women. Extending the lifetime of screening is a matter of finding the appropriate balance of benefits of cancer reduction and limitation of harms and costs of 'overscreening'. This will require moving beyond current emphasis on number of colposcopies as the metric of harm. Our commentary is meant to stimulate intellectual debate regarding the certainty of our existing knowledge base and set clear research priorities for the future.

Cancer Causes Control 2018; 29:43-50. [PMID: 29124542 PMCID: PMC5754229 DOI: 10.1007/s10552-017-0976-x] [Citation(s) in RCA: 14] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/13/2017] [Accepted: 10/28/2017] [Indexed: 10/18/2022]
Abstract
OBJECTIVE To evaluate the adoption of HPV testing and recommended extended cervical cancer screening intervals in clinical practice, we described yearly uptake of Pap/HPV cotesting and estimated length of time between normal screens by patient characteristics. METHODS We examined 55,575 Pap/HPV records from 27,035 women aged 30-65 years from the Johns Hopkins Hospital Pathology Data System between 2006 and 2013. Cotest uptake and median times to next screening test for cotests and cytology only were calculated. Adjusted hazard ratios were estimated using Cox proportional hazards models, with random effects adjustment for clustering within clinic. RESULTS Cotest usage increased from < 10% in 2006 to 78% in 2013. The median time to next screening test following normal cytology alone remained constant around 1.5 years. Screening intervals following a dual-negative cotest increased from 1.5 years in 2006/2007 to 2.5 years in 2010, coincident with increases in the proportion of women cotested. Intervals following a dual negative cotest were longer among Medicare patients (3 years) compared with privately insured women (2.5 years), and shorter among black (2 years) compared with white women (2.8 years). CONCLUSION By mid-2013 we observed broad adoption of Pap/HPV cotesting in routine screening in a large academic medical center. Increased screening intervals were observed only among cotested women, while those screened by cytology alone continued to be screened almost annually. The influence of different combinations of race and insurance on screening intervals should be further evaluated to ensure balance of screening risks and benefits in the U.S. POPULATION

Abstract
BACKGROUND European guidelines recommend primary HPV testing for cervical cancer screening. However, the starting age remains to be defined, with an undecided window between 30 and 35 years. This pilot study compares the effectiveness of primary HPV testing to that of cytology for the detection of high-grade (CIN2+) lesions stratified by age. METHODS Cotesting with LBC cytology and APTIMA® HPV (AHPV) was performed in 5053 women aged 25-65 in an opportunistic screening program in Madrid. AHPV-positive cases were referred to colposcopy and genotyped for HPV16 and 18/45 (AHPV-GT). Results were analyzed stratified in four age groups. RESULTS 454 cases (9.0%) were AHPV-positive. Women under 35 had a 30.2% CIN2+ rate, compared to 21.9% and 20.4% for women aged 35-44 or 45-54. There was a significant increase (P < .05) in the rate of CIN2+ in AHPV-GT-positive women when compared to that for other HPV types (AHPV-other), being 43.3% versus 15.7%. AHPV-GT-positive women under 35 had significantly higher rates of CIN2+ lesions than any other age-group. The sensitivity of cytology for cervical CIN2+ in APHV-positive women was 60.6%. All 4 carcinomas, including one AHPV-negative endometrial adenocarcinoma, had abnormal cytology. All cervical CIN2+ lesions biopsied were AHPV-positive. CONCLUSIONS Aptima HPV shows a significantly higher sensitivity for cervical CIN2+ lesions than cytology alone. Unexpectedly, AHPV-positive women under 35 had the highest incidence of CIN2+ lesions, particularly when they are HPV16/18/45-positive. Reconsidering HPV primary screening before the recommended age of 35 is warranted.

Abstract
Large-scale epidemiologic studies have been invaluable for elaboration of the causal relationship between persistent detection of genital human papillomavirus (HPV) infection and the development of invasive cervical cancer. However, these studies provide limited data to adequately inform models of the individual-level natural history of HPV infection over the course of a lifetime, and particularly ignore the biological distinction between HPV-negative tests and lack of infection (i.e., the possibility of latent, undetectable HPV infection). Using data from more recent epidemiological studies, this review proposes an alternative model of the natural history of genital HPV across the life span. We argue that a more complete elucidation of the age-specific probabilities of the alternative transitions is highly relevant with the expanded use of HPV testing in cervical cancer screening. With routine HPV testing in cervical cancer screening, women commonly transition in and out of HPV detectability, raising concerns for the patient and the provider regarding the source of the positive test result, its prognosis, and effective strategies to prevent future recurrence. Alternative study designs and analytic frameworks are proposed to better understand the frequency and determinants of these transition pathways.

Abstract
The objective of the presented cross-sectional-evaluation-screening study is the clinical evaluation of high-risk(hr)HPVE7-protein detection as a triage method to colposcopy for hrHPV-positive women, using a newly developed sandwich-ELISA-assay. Between 2013-2015, 2424 women, 30-60 years old, were recruited at the Hippokratio Hospital, Thessaloniki/Greece and the Im Mare Klinikum, Kiel/Germany, and provided a cervical sample used for Liquid Based Cytology, HPV DNA genotyping, and E7 detection using five different E7-assays: "recomWell HPV16/18/45KJhigh", "recomWell HPV16/18/45KJlow", "recomWell HPV39/51/56/59", "recomWell HPV16/31/33/35/52/58" and "recomWell HPVHRscreen" (for 16,18,31,33,35,39,45,51,52,56,58,59 E7), corresponding to different combinations of hrHPVE7-proteins. Among 1473 women with eligible samples, those positive for cytology (ASCUS+ 7.2%), and/or hrHPV DNA (19.1%) were referred for colposcopy. Cervical Intraepithelial Neoplasia grade 2 or worse (CIN2+) was detected in 27 women (1.8%). For HPV16/18-positive women with no triage, sensitivity, positive predictive value (PPV) and the number of colposcopies needed to detect one case of CIN2+ were 100.0%, 11.11% and 9.0 respectively. The respective values for E7-testing as a triage method to colposcopy ranged from 75.0-100.0%, 16.86-26.08% and 3.83-5.93. Sensitivity and PPV for cytology as triage for hrHPV(non16/18)-positive women were 45.45% and 27.77%; for E7 test the respective values ranged from 72.72-100.0% and 16.32-25.0%. Triage of HPV 16/18-positive women to colposcopy with the E7 test presents better performance than no triage, decreasing the number of colposcopies needed to detect one CIN2+. In addition, triage of hrHPV(non16/18)-positive women with E7 test presents better sensitivity and slightly worse PPV than cytology, a fact that advocates for a full molecular screening approach.

Abstract
OBJECTIVE To compare the risks of histologic high-grade cervical intraepithelial neoplasia (CIN) or worse after different cervical cancer screening test results between two of the largest U.S. clinical practice research data sets. METHODS The New Mexico Human Papillomavirus (HPV) Pap Registry is a statewide registry representing a diverse population experiencing varied clinical practice delivery. Kaiser Permanente Northern California is a large integrated health care delivery system practicing routine HPV cotesting since 2003. In this retrospective cohort study, a logistic-Weibull survival model was used to estimate and compare the cumulative 3- and 5-year risks of histologic CIN 3 or worse among women aged 21-64 years screened in 2007-2011 in the New Mexico HPV Pap Registry and 2003-2013 in Kaiser Permanente Northern California. Results were stratified by age and baseline screening result: negative cytology, atypical squamous cells of undetermined significance (ASC-US) (with or without HPV triage), low-grade squamous intraepithelial lesion, and high-grade squamous intraepithelial lesion. RESULTS There were 453,618 women in the New Mexico HPV Pap Registry and 1,307,528 women at Kaiser Permanente Northern California. The 5-year CIN 3 or worse risks were similar within screening results across populations: cytology negative (0.52% and 0.30%, respectively, P<.001), HPV-negative and ASC-US (0.72% and 0.49%, respectively, P=.5), ASC-US (3.4% and 3.4%, respectively, P=.8), HPV-positive and ASC-US (7.7% and 7.1%, respectively, P=.3), low-grade squamous intraepithelial lesion (6.5% and 5.4%, respectively, P=.009), and high-grade squamous intraepithelial lesion (53.1% and 50.4%, respectively, P=.2). Cervical intraepithelial neoplasia grade 2 or worse risks and 3-year risks had similar trends across populations. Age-stratified analyses showed more variability, especially among women aged younger than 30 years, but patterns of risk stratification were comparable. CONCLUSION Current U.S. cervical screening and management recommendations are based on comparative risks of histologic high-grade CIN after screening test results. The similar results from these two large cohorts from different real-life clinical practice settings support risk-based management thresholds across U.S. clinical populations and practice settings.

Abstract
Kaempferol has been identified as a potential cancer therapeutic agent by an increasing amount of evidences. However, the changes in the topography of cell membrane induced by kaempferol at subcellular- or nanometer-level were still unclear. In this work, the topographical changes of cytomembrane in human cervical cancer cell (SiHa) induced by kaempferol, as well as the role of kaempferol in apoptosis induction and its possible mechanisms, were investigated. At the macro level, MTT assays showed that kaempferol inhibited the proliferation of SiHa cells in a time- and dose-dependent manner. Flow cytometry analysis demonstrated that kaempferol could induce SiHa cell apoptosis, mitochondrial membrane potential disruption, and intracellular free calcium elevation. At the micro level, fluorescence imaging by laser scanning confocal microscopy (LSCM) indicated that kaempferol could also destroy the networks of microtubules. Using high resolution atomic force microscopy (AFM), we determined the precise changes of cellular membrane induced by kaempferol at subcellular or nanometer level. The spindle-shaped SiHa cells shrank after kaempferol treatment, with significantly increased cell surface roughness. These data showed structural characterizations of cellular topography in kaempferol-induced SiHa cell apoptosis and might provide novel integrated information from macro to nano level to assess the impact of kaempferol on cancer cells, which might be important for the understanding of the anti-cancer mechanisms of drugs.

Abstract
A challenge in implementation of sensitive HPV-based screening is limiting unnecessary referrals to colposcopic biopsy. We combined two commonly recommended triage methods: partial HPV typing and "reflex" cytology, evaluating the possibility of automated cytology. This investigation was based on 1,178 exfoliated cervical specimens collected during the enrollment phase of The Study to Understand Cervical Cancer Early Endpoints and Determinants (SUCCEED, Oklahoma City, OK). We chose a colposcopy clinic population to maximize number of outcomes, for this proof-of-principle cross-sectional study. Residual aliquots of PreservCyt were HPV-typed using Linear Array (LA, Roche Molecular Systems, Pleasanton, CA). High-risk HPV typing data and cytologic results (conventional and automated) were used jointly to predict risk of histologically defined ≥CIN2. We developed a novel computer algorithm that uses the same optical scanning features that are generated by the FocalPoint Slide Profiler (BD, Burlington, NC). We used the Least Absolute Shrinkage and Selection Operator (LASSO) method to build the prediction model based on a training dataset (n = 600). In the validation set (n = 578), for triage of all HPV-positive women, a cytologic threshold of ≥ASC-US had a sensitivity of 0.94, and specificity of 0.30, in this colposcopy clinic setting. When we chose a threshold for the severity score (generated by the computer algorithm) that had an equal specificity of 0.30, the sensitivity was 0.91. Automated cytology also matched ≥ASC-US when partial HPV typing was added to the triage strategy, and when we re-defined cases as ≥CIN3. If this strategy works in a prospective screening setting, a totally automated screening and triage technology might be possible.

Abstract
INTRODUCTION Although the utility of high-risk human papillomavirus (hrHPV) testing is established in the triage of ASC-US Papanicolaou tests from the general population, its role in women who have been treated for cervical cancer and other HPV-related cancers is less clear. MATERIALS AND METHODS Records of patients with ASC-US Papanicolaou tests and HPV testing results submitted by our gynecologic oncology service with a history of malignancy between 2006 and 2012 were reviewed. RESULTS Thirty-nine women with a history of treatment for HPV-related cancer and ASC-US Papanicolaou tests who had undergone hrHPV testing were identified. hrHPV was detected in the in specimens from 12 of the 39 patients. Among the 12 patients with ASC-US/hrHPV+ Papanicolaou tests, 2 had a subsequent Papanicolaou test with high-grade squamous intraepithelial lesion (HSIL) and 1 had a cervical biopsy that showed invasive squamous cell carcinoma. Among the 27 patients with ASC-US/hrHPV- Papanicolaou tests with pathologic follow-up, none had HSIL or worse. In patients with treated non-HPV-related cancers, hrHPV was detected in cervical/vaginal cytology specimens from 11 of 47 patients. Of 11 patients with ASCUS/hrHPV+ Papanicolaou tests, 1 had an HSIL Papanicolaou test and a negative vaginal biopsy within 18 months. None of the 36 patients with ASC-US/hrHPV- Papanicolaou tests had HSIL or worse on follow-up. CONCLUSION The rates of hrHPV positivity in ASC-US Papanicolaou tests from women treated for both HPV-related (31%) and non-HPV-related (23%) gynecologic malignancies were similar to those reported in women older than 45 years. hrHPV testing identified all women with ASC-US Papanicolaou tests who subsequently developed HSIL or worse.

Cost-Effectiveness Analysis of Universal Human Papillomavirus Vaccination Using a Dynamic Bayesian Methodology: The BEST II Study. VALUE IN HEALTH : THE JOURNAL OF THE INTERNATIONAL SOCIETY FOR PHARMACOECONOMICS AND OUTCOMES RESEARCH 2015; 18:956-68.

Abstract
BACKGROUND Human papillomavirus (HPV) plays a role in the development of benign and malign neoplasms in both sexes. The Italian recommendations for HPV vaccines consider only females. The BEST II study (Bayesian modelling to assess the Effectiveness of a vaccination Strategy to prevent HPV-related diseases) evaluates 1) the cost-effectiveness of immunization strategies targeting universal vaccination compared with cervical cancer screening and female-only vaccination and 2) the economic impact of immunization on various HPV-induced diseases. OBJECTIVE The objective of this study was to evaluate whether female-only vaccination or universal vaccination is the most cost-effective intervention against HPV. METHODS We present a dynamic Bayesian Markov model to investigate transmission dynamics in cohorts of females and males in a follow-up period of 55 years. We assumed that quadrivalent vaccination (against HPV 16, 18, 6, and 11) is available for 12-year-old individuals. The model accounts for the progression of subjects across HPV-induced health states (cervical, vaginal, vulvar, anal, penile, and head/neck cancer as well as anogenital warts). The sexual mixing is modeled on the basis of age-, sex-, and sexual behavioral-specific matrices to obtain the dynamic force of infection. RESULTS In comparison to cervical cancer screening, universal vaccination results in an incremental cost-effectiveness ratio of €1,500. When universal immunization is compared with female-only vaccination, it is cost-effective with an incremental cost-effectiveness ratio of €11,600. Probabilistic sensitivity analysis shows a relatively large amount of parameter uncertainty, which interestingly has, however, no substantial impact on the decision-making process. The intervention being assessed seems to be associated with an attractive cost-effectiveness profile. CONCLUSIONS Universal HPV vaccination is found to be a cost-effective choice when compared with either cervical cancer screening or female-only vaccination within the Italian context.

Abstract
New cervical cancer screening guidelines in the US and many European countries recommend that women get tested for human papillomavirus (HPV). To inform decisions about screening intervals, we calculate the increase in precancer/cancer risk per year of continued HPV infection. However, both time to onset of precancer/cancer and time to HPV clearance are interval-censored, and onset of precancer/cancer strongly informatively censors HPV clearance. We analyze this bivariate informatively interval-censored data by developing a novel joint model for time to clearance of HPV and time to precancer/cancer using shared random-effects, where the estimated mean duration of each woman's HPV infection is a covariate in the submodel for time to precancer/cancer. The model was fit to data on 9,553 HPV-positive/Pap-negative women undergoing cervical cancer screening at Kaiser Permanente Northern California, data that were pivotal to the development of US screening guidelines. We compare the implications for screening intervals of this joint model to those from population-average marginal models of precancer/cancer risk. In particular, after 2 years the marginal population-average precancer/cancer risk was 5%, suggesting a 2-year interval to control population-average risk at 5%. In contrast, the joint model reveals that almost all women exceeding 5% individual risk in 2 years also exceeded 5% in 1 year, suggesting that a 1-year interval is better to control individual risk at 5%. The example suggests that sophisticated risk models capable of predicting individual risk may have different implications than population-average risk models that are currently used for informing medical guideline development.
