RESUMO
This research paper evaluates the efficacy of co-testing in precluding cervical cancer, with a particular focus on distinguishable outcomes of the human papillomavirus (HPV) vs. cytology tests. A retrospective review of 5948 patients, who tested positive for high-risk HPV but showed negative cytologic findings, revealed that 15.006% tested positive in subsequent screenings. A comparative analysis of various commercial HPV tests highlighted the precision of mRNA-based HPV testing by Aptima (Hologic) in reducing the likelihood of false-negative cytology. The paper challenges the conviction that a negative cytology alone suffices advocating for a condensed testing interval in instances of positive HPV outcomes, thereby facilitating earlier intervention and optimal preventive care. These findings unveil an exigency for reconsidering preventive strategies based on test outcomes.

Introduction: Since 1 January 2020, diagnostic confirmation of abnormalities detected in the context of cytology/HPV co-testing in cervical cancer screening under the statutory health insurance scheme in women aged 35 and over has been performed according to predefined algorithms. A colposcopy is indicated even in the case of borderline/low-grade cytological changes and/or HPV persistence. In this article we compare the histology findings after primary screening examinations in 2020/21 with those from 2018/19, thus also comparing the results of two different screening approaches. Patients and Methods: Our analysis included all of the cytology, HPV, and histology results from all primary screening examinations, as well as the resulting diagnostic confirmation and curative cases, that could be obtained by 30 June 2023. In 2018/19 these comprised 650600 cytology and 1804 histology findings, and in 2020/21 there were 491450 cytology and 7156 histology findings. The absolute numbers of histology findings and the percentage ratios of these to all cytological diagnoses are presented with comparison factors. Results: In 2020/21 there were 5.2 times more histology findings in relation to all previous cytology examinations than in 2018/19, as well as 10.6 times more biopsies, 3.8 times more conizations, and 1.2 times more hysterectomies. There was a particularly high increase in diagnostic confirmation of borderline/low-grade or only HPV-positive findings. With co-testing, 12.7 times more CIN1, 6.4 times more CIN2, and 3.5 times more CIN3 lesions were diagnosed. The proportion of biopsies without dysplasia was 7.6 times higher than in previous years. Cervical carcinomas were diagnosed 1.8 times more frequently, and endometrial carcinomas 0.7 times less frequently. Conclusion: More CIN lesions were found with co-testing, but the increase in histology findings of low-grade or no dysplasia was far greater than findings of CIN3. Lesions not requiring treatment accounted for 94.4% of biopsy results in 2020/21. The use of computer-assisted LBC with progression markers could reduce this.
RESUMO
OBJECTIVES: The longer-term impact of introducing human papillomavirus (HPV) testing into routine cervical cancer screening on precancer and cancer rates by histologic type has not been well described. Calendar trends in diagnoses were examined using data from Kaiser Permanente Northern California, which introduced triennial HPV and cytology co-testing in 2003 for women aged ≥30 years. METHODS: We examined trends in cervical precancer (cervical intraepithelial neoplasia grade 3 [CIN3] and adenocarcinoma in situ [AIS]) and cancer (squamous cell carcinoma [SCC] and adenocarcinoma [ADC]) diagnoses per 1000 screened during 2003-2018. We examined ratios of squamous vs. glandular diagnoses (SCC:ADC and CIN3:AIS). RESULTS: CIN3 and AIS diagnoses increased approximately 2% and 3% annually, respectively (ptrend < 0.001 for both). While SCC diagnoses decreased by 5% per annually (ptrend < 0.001), ADC diagnoses did not change. These patterns were generally observed within each age group (30-39, 40-49, and 50-64 years). ADC diagnoses per 1000 screened did not change even among those who underwent co-testing starting in 2003-2006. SCC:ADC decreased from approximately 2.5:1 in 2003-2006 to 1.3:1 in 2015-2018 while the CIN3:AIS remained relatively constant, â¼10:1. CONCLUSIONS: Since its introduction at KPNC, co-testing increased the detection of CIN3 over time, which likely caused a subsequent reduction of SCC. However, there has been no observed decrease in ADC. One possible explanation for lack of effectiveness against ADC is the underdiagnosis of AIS. Novel strategies to identify and treat women at high risk of ADC need to be developed and clinically validated.

BACKGROUND: Cytology and high-risk human papilloma virus (hrHPV) cotesting is the mainstay in the detection of cervical carcinoma. METHODS: Endocervical adenocarcinoma (EAC) is divided into HPV-associated adenocarcinoma (HPVA) and HPV-independent adenocarcinoma (HPVI) by the World Health Organization classification (2020). The detection effect of cotesting is suggested to be different among EAC subtypes and precursors, but has not well-documented yet. In this study, the authors retrospectively analyzed cotesting among adenocarcinoma in situ (AIS), HPVA, and HPVI. The cohort included 569 AIS and 498 EAC consisting of 371 (74.5%) HPVA, 111 (22.3%) HPVI, and 16 (3.2%) adenocarcinoma, not otherwise specified. RESULTS: The authors found that AIS patients were significantly younger than HPVA and HPVI (mean ± SD, years: 40.7 ± 8.6; HPVA, 44.8 ± 9.3; HPVI, 50.0 ± 11.3; p < .001) and had a higher prevalence of concurrent squamous intraepithelial lesions (75.5%, HPVA, 37.2%; HPVI, 12.6%; p < .001). The detection rate of hrHPV test or cytology was substantially higher in AIS and HPVA than in HPVI (97.7% and 90.2% vs. 16.5%, p < .001, or 71.1% and 71.9% vs. 60.7%, p = .042, respectively). Cytology and hrHPV cotesting was superior to a single test in the detection of EAC and AIS. The detection rate of cotesting amounted to 100% in AIS and 94.3% in HPVA but was substantially lower in HPVI (72.2%) (p < .001). CONCLUSIONS: The authors conclude that cytology and hrHPV cotesting can maximize the detection effect for HPVA and AIS but is not optimal for HPVI.

The Human Papillomavirus (HPV) causes cervical cancer, the fourth most common cause of death in women in the United States (US). Several major screening clinical trials have demonstrated that high risk HPV (HR-HPV) DNA primary screen is more sensitive at determining the risk of cervical intraepithelial neoplasia level 3 or higher (CIN ≥ 3) than cytology alone and is similar to co-testing. In this cross-sectional study, we characterized a Hispanic population of 18,052 women ages 21-70 years with HR-HPV DNA testing and cytology to determine the prevalence of HR-HPV in the population and determine the likelihood of high grade squamous intraepithelial lesion (HSIL). We also compared cytology, HR-HPV DNA testing, and co-testing strategies to determine sensitivity, specificity, positive predictive value, and negative predictive value for HSIL in cervical biopsies. Results show that HR-HPV had a slightly higher sensitivity (94.2% vs 92.3%) compared to cytology for all high-grade disease (CIN2/3).
RESUMO
INTRODUCTION: In the past 2 decades, cervical cancer screening guidelines in the United States have undergone numerous revisions with recent greater emphasis on primary high-risk human papillomavirus (hrHPV) testing. MATERIALS AND METHODS: We examine the trends of Papanicolaou test and hrHPV testing at our large academic center across 4 years (2006, 2011, 2016, and 2021) over a 15-year period. The number of ThinPrep Papanicolaou and hrHPV tests, as well as the triggers for HPV testing, were retrospectively analyzed. RESULTS: A total of 308,355 Papanicolaou tests and 117,477 hrHPV tests were reported across the 4 years. The number of Papanicolaou tests performed decreased nearly 3-fold over the study period, with only 43,230 Papanicolaou tests performed in 2021. The HPV test to Papanicolaou test ratio increased: 17% of Papanicolaou tests had an associated HPV test in 2006, whereas 72% of Papanicolaou tests ordered in 2021 had a companion hrHPV. The use of co-testing also increased. Overall, 73% were co-tests and 27% were reflexively ordered in the 4 one-year time periods. Co-tests constituted only 46% of HPV tests in 2006, but this increased to 93% in 2021. The percentage of positive hrHPV results decreased; in 2006, 18.3% of cases were positive, dropping to 8.6% in 2021 due to the marked increase in co-testing. Stratifying by diagnostic category, hrHPV results have remained relatively constant. CONCLUSION: With the numerous recent revisions of cervical screening guidelines, screening strategies at our institution reflected these changes in clinical practice. Papanicolaou and HPV co-testing became the most common screening method for women 30 to 65 years of age in our cohort.

Human papillomavirus (HPV) testing for cervical screening increases diagnosis of precancer and reduces the incidence of cervical cancer more than cytology alone. However, real-world evidence from diverse practice settings is lacking for the United States (U.S.) to support clinician adoption of primary HPV screening. Using a population-based registry, which captures all cervical cytology (with or without HPV testing) and all cervical biopsies, we conducted a real-world evidence study of screening in women aged 30 to 64 years across the entire state of New Mexico. Negative cytology was used to distinguish cotests from reflex HPV tests. A total of 264 198 cervical screening tests (with exclusions based on clinical history) were recorded as the first screening test between 2014 and 2017. Diagnoses of cervical intraepithelial neoplasia grades 2 or 3 or greater (CIN2+, CIN3+) from 2014 to 2019 were the main outcomes. Of cytology-negative screens, 165 595 (67.1%) were cotests and 4.8% of these led to biopsy within 2 years vs 3.2% in the cytology-only group. Among cytology-negative, HPV tested women, 347 of 398 (87.2%) CIN2+ cases were diagnosed in HPV-positive women, as were 147 of 164 (89.6%) CIN3+ cases. Only 29/921 (3.2%) CIN3+ and 67/1964 (3.4%) CIN2+ cases were diagnosed in HPV-negative, cytology-positive women with biopsies. Under U.S. opportunistic screening, across a diversity of health care delivery practices, and in a population suffering multiple disparities, we show adding HPV testing to cytology substantially increased the yield of CIN2+ and CIN3+. CIN3+ was rarely diagnosed in HPV-negative women with abnormal cytology, supporting U.S. primary HPV-only screening.

OBJECTIVES: Conducting human immunodeficiency virus (HIV) testing in emergency departments (EDs) can be an effective approach to testing and reaching populations at highest risk of contracting HIV. METHODS: All gonorrhea and chlamydia (G/C) and HIV tests ordered in the Cleveland Clinic Health System's 14 EDs were included in the analysis. Data were collected from electronic health records. Descriptive statistics, with medians and means, were computed. RESULTS: From January 1, 2019, to December 31, 2021, we reviewed ED visits for the purpose of sexually transmitted infection (STI) screening, with an emphasis on G/C screening. In October 2019, both HIV rapid testing and G/C testing began across all 14 Cleveland Clinic EDs. The overall rate of co-testing for HIV when obtaining a G/C test for STI evaluation increased overall to around 30% for our health system EDs, with some individual EDs approaching 60%. CONCLUSIONS: The approach the Cleveland Clinic implemented is an effective way to test for HIV in the ED. Local health departments and stakeholders in HIV communities should support and collaborate with EDs in their jurisdictions to accelerate HIV testing initiatives by using an HIV plus G/C co-testing metric.

Cervical cancer screening is an essential component of preventative health care. Although rates of cervical cancer have decreased over the last 50 years, survival has not changed dramatically, and there are significant discrepancies in disease detection by race. Multiple national organizations contribute to the recommendations for cervical cancer screening timing, testing modalities, and management. This article aims to summarize the current understanding of cervical cancer pathogenesis, options for cervical cancer screening, and the shift in guidelines toward risk-based clinical management.

Cervical screening is increasingly switching to human papillomavirus (HPV) testing. In many settings, the switch has involved one or several co-tests (testing using both cytology and HPV) in the screening guidelines, to ensure safety. When Sweden switched to HPV testing in 2015 the guidelines included a co-test at age 41. To evaluate the effect of co-testing, we identified all 208,701 women resident in Sweden who in 2019 were 40-42 years old and thus eligible for co-testing. All cervical samples, the results of the test and of the subsequent biopsies were identified in the Swedish National Cervical Screening Registry. Out of the 10,643 women with co-testing in screening, there were 197 women with a subsequent biopsy with high-grade cervical neoplasia or worse (CIN2+). Among these 197 women, 189 had a screening test positive for both HPV and cytology, 6 women were HPV+/Cyt- and 2 women were HPV-/Cyt+. There were 7115 women with a co-test outside of the screening program. Among these, 325 women had a CIN2+ in histopathology, 290 were double positive, 13 women were cyt+/HPV-, and 11 women each were HPV+/cyt- and HPV-/Cyt-. In summary, the additional yield of CIN2+ with co-testing was 2 cases per 10,643 women as compared with 195/10,643 CIN2+ cases detected with HPV screening alone. However, for cervical samples taken outside the screening program (e.g. taken on a clinical indication) there was an increased yield (314 CIN2+ cases detected with co-testing as compared to 301 cases with HPV screening).

Introduction On 1 January 2020 the screening programme for the prevention of cervical cancer in women from the age of 35 years of the Statutory Health Insurance (GKV) in Germany changed from an annual cytology examination to cytological and HPV co-testing carried out every three years. A large standard diagnostics laboratory has been using liquid-based cytology (LBC) with computer-assisted screening (CAS) since 1 January 2020 to assess the samples. Patients and Methods The cytological and HPV results for all cases examined with co-testing from 01.01.2020 to 31.12.2021 (n = 395759) are reported and the cytology results obtained using co-testing are compared with the results obtained using only conventional primary cytology screening from the two previous years (n = 588192). Cytology tests were carried out using LBC and computer-assisted screening. A DNA PCR test which can identify 14 types of HPV was used for HPV testing. The cytology results are reported using the Munich Nomenclature III, which is mandatory in Germany, and converted to The Bethesda System (TBS). Problems occurring during the implementation phase are described here. Results A total of 983951 cases who had primary screening between 01.01.2018 and 31.12.2021 were analysed. The HR HPV-positive rate with co-testing for all age groups was 6.41%. Of this group, 16.31% were positive for HPV-16, 4.43% for HPV-18, and 71.40% had one or more of the other 12 HR HPV types. Several different HPV types were identified in 7.86% of cases. The HPV-positive rate for cases with unremarkable cytological findings was 4.03%. 0.46% of tests were technically invalid. The results of primary cytology screening for 2020/21 (LBC) were: Pap 0 (TBS: unsatisfactory) 0.09%, Pap I and Pap II-a (NILM) 96.82%, Pap II-p/g (~ASC-US/AGC) 1.23%, Pap III-p/g (~ASC-H/AGC) 0.19%, Pap III D1 (LSIL) 1.08%, Pap III D2 (HSIL) 0.31%, Pap IVa/b-p/g (HSIL/AIS) 0.18%, and Pap V-p/g (carcinoma) 0.01%. The rates for 2018/19 (conventional cytology without routine testing for HPV) were significantly higher for Pap II-p/g (1.64%) and significantly lower for Pap III-p/g (0.13%), Pap III D1 (0.45%), Pap III D2 (0.10%) and Pap IVa/b-p/g (0.05%). Conclusion Evaluation of the data for the two first years of cytology and HPV co-testing from a standard diagnostics laboratory found low HR HPV-positive rates. As regards the cytology tests, the Pap II-p/g rate was significantly lower and the ≥ Pap III rate was significantly higher compared to the two previous years. This points to a probable higher sensitivity and specificity of the new method.
RESUMO
OBJECTIVE: To explore rates of under- and overscreening for cervical cancer among a national cohort. METHODS: The MarketScan database, a national administrative database of employee-sponsored insurance, was queried for elements relevant to cervical cancer screening among women aged 21-65 with 6 years of continuous enrollment (2015-2019). Average-risk women were defined as those without high-risk medical conditions or abnormal screening histories, and without evidence of hysterectomy with removal of the cervix for benign indications. Average-risk women were considered adequately screened if they had Pap tests alone at 2.5-3.5 year intervals, or HPV tests or co-tests at 4.5-5.5 year intervals. Logistic regressions were used to predict the odds of receiving guideline-adherent screening, underscreening, and overscreening. RESULTS: Among 1,872,809 eligible patients, 1,471,063 (78.5%) qualified for routine screening. Of these, only 18.1% received guideline-adherent screening, and 25.4% were unscreened during the 6-year period. Younger women (aged 21-39) were more likely to be overscreened [OR 1.46]. Older women (aged 50-64) were more likely to be underscreened or unscreened during the study period [OR 2.54]. Guideline-adherent screening was highest with HPV testing alone (80%) followed by co-testing (44%), and lowest with cytology alone (15%). A total of 329,062 women in this general population sample (18%) met high-risk criteria that required increased frequency of screening. CONCLUSIONS: High rates of both underscreening and overscreening indicate a need for additional strategies to improve guideline-adherent care. CLINICAL TRIAL REGISTRATION: N/A.

INTRODUCTION: The screening program for cervical cancer in Sweden recommends the use of primary human papillomavirus (HPV) screening for women aged ≥30 to 65 years. Co-testing with both HPV analysis and cytology is recommended at the first screening after the age of 40 years. To fulfil co-testing, all screened women aged 40-42 years within the region of Skåne were co-tested. The aim of the audit was to investigate the proportion of severe dysplasia as diagnosed by cytology and histological follow-up among women with Aptima HPV-negative tests. We also calculated the cost of adding the cytology to the HPV primary screening program. MATERIAL AND METHODS: The local cytology registry was used to identify women aged 40-42 years who attended screening and were co-tested during the 4 years from January 2017 to December 2020. The Aptima HPV messenger RNA assay detects 14 HPV types. For Aptima HPV-negative women with high-grade cytology or histological high-grade squamous intraepithelial lesions (HSILs), we performed extended HPV typing for 40 HPV types with polymerase chain reaction using modified GP5+/6+ primers followed by a Luminex assay. To estimate the added cost of using cytology to identify each histologically confirmed cervical HSIL case among Aptima HPV-negative women, we used the current cost of 21.2 per cytology evaluation at our laboratory. RESULTS: Of 19 599 women, 5.8% (1137/19 599) had abnormal cytology. Among Aptima HPV-negative women, 0.11 (2/18 132) had histologically confirmed HSIL. One of the women was infected with HPV18 and the other with HPV73 at the diagnosis of HSIL. The calculated cost to find one HSIL, by adding cytology to HPV-negative cases, was approximately 200 000. CONCLUSIONS: The clinical benefit of a single cytology co-test added to an HPV-based screening program in women aged 40-42 years appears doubtful and economically unreasonable.

PURPOSE: This study has two aims: determine the prevalence of CIN3 + in patients with discordant cotesting, defined as negative cytology and positive human papillomavirus (HPV) testing, and identify factors (including HPV strain) associated with CIN3 + , defined as cervical intraepithelial neoplasia (CIN) 3 or cancer within this population. METHODS: We conducted a retrospective chart review of women age 30-65 with intact cervices who had discordant cotesting results between January 1, 2013 and September 1, 2018, at an academic medical center. We used the t test for continuous variables and the Chi-square test for categorical variables to compare women with and without CIN3 + . To identify factors associated with CIN3 + , we performed univariate and multivariate logistic regression. RESULTS: The primary outcome was the prevalence of CIN3 + based on pathologic diagnosis following biopsy or excisional procedure. Among 375 patients with discordant co-testing, the mean age was 43.8 years, 58.4% were parous, and 84.8% were white. Overall, 43/375 (12.0%) had CIN3 + and 7/375 (1.9%) had AIS. On logistic regression, only parity ≥ 1 (p = 0.04, adjusted OR = 2.23, CI = 1.06-4.68) was significantly associated with CIN3 + . HPV-18 was less likely to be associated with CIN3 + (p = 0.02, adjusted OR 0.08, CI 0.01-0.65) but was present in 43% of AIS cases. HPV16 and other HR-HPV strains were highly associated with CIN3 + . CONCLUSION: Women with discordant cotesting are at significant risk for CIN3 + . We recommend that biopsy be performed at the time of indicated colposcopy for all patients with discordant cotesting to assess for high-grade dysplasia.

BACKGROUND: The guidelines for managing abnormal cervical cancer screening tests changed from a results-based approach in 2012 to a risk-based approach in 2019. OBJECTIVE: We estimated the cost-effectiveness of the 2019 management guidelines and the changes in resource utilization moving from 2012 to 2019 guidelines. STUDY DESIGN: We utilized a previously published model of cervical cancer natural history and screening to estimate and compare the lifetime costs and the number of screens, colposcopies, precancer treatments, cancer cases, and cancer deaths associated with the 2012 vs 2019 management guidelines. We assessed these guidelines under the scenarios of observed screening practice and perfect screening adherence to 3-year cytology starting at age 21, with a switch to either 3-year or 5-year cytology plus human papillomavirus cotesting at age 30. In addition, we estimated the lifetime costs and life years to determine the cost-effectiveness of shifting to the 2019 management guidelines. RESULTS: Under the assumptions of both observed screening practice and perfect screening adherence with a strategy of 3-year cytology at ages 21 to 29 and switching to 3-year cotesting at age 30, the management of the screening tests according to the 2019 guidelines was less costly and more effective than the 2012 guidelines. For 3-year cytology screening at ages 21 to 29 and switching to 5-year cotesting at age 30, the 2019 guidelines were more cost-effective at a willingness-to-pay threshold of $100,000 per life year gained. Across all scenarios, the 2019 management guidelines were associated with fewer colposcopies and cancer deaths. CONCLUSION: Our model-based analysis suggests that the 2019 guidelines are more effective overall and also more cost-effective than the 2012 guidelines, supporting the principle of "equal management of equal risks."

OBJECTIVES: To investigate the prevalence of high-risk human papillomavirus (HPV)-negative cervical intraepithelial neoplasia (CIN) and invasive cervical carcinoma (ICC) and to analyze the distribution of other genotypes in this subset. METHODS: In total, 431 women who underwent excisional surgical treatment for CIN or ICC at the European Institute of Oncology, Milan, Italy, from January 2016 to December 2017 were retrospectively analyzed. The Linear Array HPV genotyping test (Roche Diagnostics) was performed on a postaliquot from high-risk-HPV-negative liquid-based cervical specimens, when available. Patient characteristics and the prevalence of high-risk-HPV-negative CIN grade 2 or worse (CIN2+) were tabulated. We used t tests to compare age between high-risk-HPV-positive and high-risk-HPV-negative patients. RESULTS: Overall, 8.9% of CIN2+ and 7.5% of ICC cases were high-risk HPV negative. There was no age difference between high-risk-HPV-negative CIN2+ women (mean [SD], 41.3 [8.7] years) and high-risk-HPV-positive women (mean [SD], 39.5 [9.0] years) (P = .28). The Linear Array result was available in 22 cases. Most high-risk-HPV-negative patients were positive for a single other genotype infection (32.6%). HPV 73 was the most prevalent genotype, followed by HPV 53 and HPV 84. HPV 26 was detected in 1 case of ICC. CONCLUSIONS: Our results showed a not-negligible proportion of high-risk-HPV-negative CIN2+, suggesting that cotesting would not miss these cases.

Failure to follow-up women after abnormal cervical screening could lead to cervical cancers, yet little is known about adherence to recommended follow-up after abnormal co-testing [cytology and high-risk human papillomavirus (hrHPV) testing]. We documented clinical management following cervical screening by co-testing in a diverse population-based setting. A statewide surveillance program for cervical screening, diagnosis, and treatment was used to investigate all cytology, hrHPV and biopsy reports in the state of New Mexico from January 2015 through August 2019. Guideline-adherent follow-up after co-testing required 1) biopsy within 6 months for low-grade cytology if positive for hrHPV, for high-grade cytology irrespective of hrHPV, and for HPV 16/18 positive results irrespective of cytology and; 2) repeat co-testing within 18 months if cytology was negative and hrHPV test was positive (excluding types 16/18). Screening co-tests (2015-2017) for 164,522 women were analyzed using descriptive statistics, Kaplan Meier curves, and pairwise comparisons between groups. Guideline adherence was highest when both cytology and hrHPV tests were abnormal, ranging from 61.7% to 80.3%. Guideline-adherent follow-up was lower for discordant results. Women with high-grade cytology were less likely to receive a timely biopsy when hrHPV-testing was negative (48.1%) versus positive (83.3%) (p < 0.001). Only 47.9% of women received biopsies following detection of HPV16/18 with normal cytology, and 30.8% received no follow-up within 18-months. Among women with hrHPV-positive normal cytology without evidence of HPV 16/18 infection, 51% received no follow-up within 18 months. Provider education and creation of robust recall systems may help ensure appropriate follow-up of abnormal screening results.

OBJECTIVE: To determine eligibility for discontinuation of cervical cancer screening. METHODS: Women aged 64 with employer-sponsored insurance enrolled in a national database between 2016 and 2018, and those aged 64-66 receiving primary care at a safety net health center in 2019 were included. Patients were evaluated for screening exit eligibility by current guidelines: no evidence of cervical cancer or HIV-positive status and no evidence of cervical precancer in the past 25 years, and had evidence of either hysterectomy with removal of the cervix or evidence of fulfilling screening exit criteria, defined as two HPV screening tests or HPV plus Pap co-tests or three Pap tests within the past 10 years without evidence of an abnormal result. RESULTS: Of the 590,901 women in the national claims database, 131,059 (22.2%) were eligible to exit due to hysterectomy (1.6%) or negative screening (20.6%). Of the 1544 women from the safety net health center, 528 (34.2%) were eligible to exit due to hysterectomy (9.3%) or negative screening (24.9%). Most women did not have sufficient data available to fulfill exit criteria: 382,509 (64.7%) in the national database and 875 (56.7%) in the safety net hospital system. Even among women with 10 years of insurance claims data, only 41.5% qualified to discontinue screening. CONCLUSIONS: Examining insurance claims in a national database and electronic medical records at a safety net institution led to remarkably similar findings: two thirds of women fail to qualify for screening exit. Additional steps to ensure eligibility prior to screening exit may be necessary to decrease preventable cervical cancers among women aged >65. CLINICAL TRIAL REGISTRATION: N/A.

BACKGROUND: Human papillomavirus testing as an established screenings test allow for the early detection and treatment of cervical cancer. Testing positive for HPV may have adverse consequences for women. This study aimed to explore the psychological impacts of testing positive for HPV on women in a developing country with a distinct cultural and religious background. METHODS: Qualitative face-to-face semi-structured interviews were conducted with 40 Iranian women who received a positive high-risk HPV result. Content analysis approach was used to data analysis through MAXQDA10. RESULTS: Three main categories were emerged: initial confrontation; STD-related psychological burden; and rebuilding health. Initial reactions to positive HPV results were shock, unrealistic fear, confusion, distress, and financial concerns. Stigma was manifested in form of self-blame, fear of HPV-disclosure, negative body image, being stigmatized by healthcare providers, and receiving health care anonymously. Refusal to use insurance services showed how evident and powerful the stigma was. Most women reported lifestyles and sexual behaviors modifications to help their immune system to clear HPV; indicating that the screening can work as a valuable opportunity to improve women's physical and sexual health. Regular follow-up, safe sex and a focus on spirituality enable women infected with HPV to take control of the situation. Worrying about other HPV-linked cancers (oropharynx and anal) and fears of partner infection indicated that women consider HPV to be more than just a cause of cervical cancer. CONCLUSIONS: The findings implied to the HPV-positive women's need to support and factual information. Designing and implementing interventions that mitigate the psychological effect of positive HPV test results can highlight the potential benefits of screening for women's health.
