Gynecol Oncol Rep 2024; 54:101421. [PMID: 38881560 PMCID: PMC11176621 DOI: 10.1016/j.gore.2024.101421] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/10/2024] [Revised: 05/14/2024] [Accepted: 05/17/2024] [Indexed: 06/18/2024] Open
Abstract
Vaginal self collection (SC) is safe and effective for human papillomavirus (HPV) testing and can increase cervical cancer screening coverage for underserved women. To better understand the impact of SC methodology on HPV test outcomes, empirical testing was conducted using different swab collection workflows. Deposition of the collection swab into resuspension buffer resulted in a 2.4-cycle reduction in threshold detection of human beta-hemoglobin during PCR when compared to "swirl-and-toss". In addition, reducing the swab resuspension volume from 10 mL to 3 mL resulted in a 2.6-cycle reduction in threshold detection of human beta-globin. A systematic literature search (01/01/2020 to 08/02/2023) of Ovid Medline and Embase, followed by data extraction and analysis, was conducted to further assess the impact of resuspension volume on performance following SC. HPV test performance for SC, relative to clinician collection (CC), was calculated for detection of cervical pre-cancer. Data were stratified by the resuspension volume ratio of SC to CC being either ≥ 1.0 or < 1.0. SC with a volume ratio of ≥ 1.0 and < 1.0 had a relative ≥ CIN2 sensitivity of 92.0 % (95 % CI: 88.0, 96.0) and 97.0 % (95 % CI: 94.0, 100), respectively. Taken together, these results suggest that SC conditions can be modified to optimize sample recovery and performance, as part of cervical cancer screening.

Cancer Epidemiol Biomarkers Prev 2024; 33:1037-1045. [PMID: 38546394 DOI: 10.1158/1055-9965.epi-24-0046] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/10/2024] [Revised: 02/27/2024] [Accepted: 03/26/2024] [Indexed: 08/02/2024] Open
Abstract
BACKGROUND High-risk human papillomavirus (hrHPV)-based cervical cancer screening in the Netherlands led to a substantial increase in number of colposcopy referrals and low-grade lesions detected. Genotyping strategies may be employed to lower the screening-related burden. METHODS We evaluated 14 triage strategies with genotyping (HPV16/18 or HPV16/18/31/33/45/52/58) for hrHPV-positive borderlineormilddyskaryosis (BMD)ornormal cytology,usingdata from a population-based hrHPV-based screening trial with 5-year interval (POBASCAM). We considered colposcopy referral at baseline, after 6-month repeat cytology and after 5-year hrHPV testing. Performance was evaluated by one-round positive and negative predictive value (PPVandNPV) for CIN3+ and by two-roundcolposcopy referral rate. To identify efficient strategies, they were ordered by the one-round colposcopy referral rate. Adjacent strategies were compared by the marginal PPV for detecting one additional CIN3+ (mPPV). RESULTS The most conservative strategy (repeat cytology after BMD and HPV16/18/31/33/45/52/58-positive normal cytology, next round otherwise) yielded an mPPV of 28%, NPV of 98.2%, and two-round colposcopy referral rate of 47.2%. Adding direct referral after BMD or genotype-positive BMD yielded an mPPV ≤ 8.2%, NPV ≥ 98.5% and an increase in colposcopy referral rate of 1.9% to 6.5%. Adding direct referral after HPV16/18-positive normal cytology yielded an mPPV ≤ 3.5%, NPV ≥ 99.5% and an increase in colposcopy referral rate of 13.9%. CONCLUSIONS Direct colposcopy referral of women with BMD or normal cytology is unlikely to be efficient, but genotype-guided direct referral after BMD may be considered because the increase in colposcopies is limited. IMPACT hrHPV screening programs can become very efficient when immediate colposcopy referral is limited to women at highest CIN3+ risk. See related In the Spotlight, p. 979.

Performance of urine samples compared to cervical samples for detection of precancer lesions among HPV-positive women attending colposcopy clinic in Mexico City. Cancer Causes Control 2024; 35:935-942. [PMID: 38368574 PMCID: PMC11129980 DOI: 10.1007/s10552-024-01852-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/29/2023] [Accepted: 01/14/2024] [Indexed: 02/19/2024]
Abstract
BACKGROUND High-risk human papillomavirus (hrHPV) detection in self-collected urine samples (SeCUS) may be a promising alternative for cervical cancer screening because of its greater acceptability, as long as it can offer comparable sensitivity to clinician-collected cervical samples (CCoS) for detecting precancer lesions. OBJECTIVE To evaluate the performance of the SeCUS compared to that of the CCoS for cervical intraepithelial neoplasia grade 3 (CIN3) detection among hrHPV-positive women receiving colposcopy in Mexico City using different specific extended HPV typing procedures: HPV16/18, HPV16/18/35/39/68 or HPV16/18/35/39/68/31. METHODS From March 2017 to August 2018, 4,158 female users of the cervical cancer screening program at Tlalpan Sanitary Jurisdiction in Mexico City were invited to participate in the FRIDA-Tlalpan study. All participants provided ≥ 30 mL of SeCUS, and then a CCoS was obtained with Cervex-Brush®, which was used for hrHPV typing. Participants who tested positive for hrHPV in CCoS were referred for colposcopy for diagnostic confirmation, and all SeCUS of these women were also tested for hrHPV typing. RESULTS In total, 561 hrHPV-positive women were identified by CCoS via colposcopy, and 82.2% of the SeCUS of these women were also hrHPV positive. From both CCoS and SeCUS, 7 cases of CIN3 were detected. Considering HPV16/18 typing, CCoS and SeCUS detected 4 cases of CIN3, but after HPV16/18/35/39/68/31 extension typing, both CCoS and SeCUS detected all 7 of the CIN3 cases among the hrHPV-positive women. CONCLUSIONS Using extended hrHPV typing based on HPV16/18/35/39/68/31, our results suggest that the performance of SeCUS may be equivalent to that of CCoS for detecting CIN3 lesions. Although our results are inconclusive, they support the hypothesis that SeCUS may be an attractive alternative worthy of further research.

Abstract
The introduction of Human Papillomavirus (HPV) testing in cervical cancer screening enhanced the opportunity to introduce self-collection as an innovative approach to improve coverage rates. Validation and standardization of the pre-analytical and analytical procedures are crucial for the quality assurance of HPV tests on self-collected samples. This study evaluated the analytical performance and the stability of self-collected vaginal samples resuspended in 5 mL of two non-alcohol-based media, eNat® and MSwab® compared to a professionally collected cervical sample, resuspended in 20 mL ThinPrep®, for the detection of high-risk HPV (hrHPV). The impact of the suspension volumes on analytical performance was also evaluated (2 and 5 ml). A good analytical concordance in hrHPV detection in cervical and vaginal self-collected swabs suspended in 5 ml of both non-alcohol-based media was demonstrated (eNat®: 91.2 %, k = 0.821; MSwab®: 91.4 %; k = 0.798). A similar analytical performance was found for samples resuspended in 2 mL (eNat®: 92.9 %, k = 0.811; MSwab®: 92.9 %, k = 0.811) compared to cervical samples. Good nucleic acid stability was demonstrated for vaginal samples stored at 20-25 °C and 37 °C for up to 4 weeks. Results of this preliminary study support the introduction of these media for vaginal self-sampling-based prevention programs. Nevertheless, further research is necessary to evaluate clinical accuracy in larger settings.

Abstract
INTRODUCTION Long-term exposure to high-risk human papillomavirus (Hr-HPV) is a well-known necessary condition for development of cervical cancer. The aim of this study is to screen for Hr-HPV using vaginal self-sampling, which is a more effective approach to improve women's adherence and increase screening rates. METHODS This pilot study included a total of 100 Women living with HIV (WLWHIV), recruited from the Center for Listening, Care, Animation, and Counseling of People Living with HIV in Bamako. Hr-HPV genotyping was performed on Self-collected samples using the Cepheid GeneXpert instrument. RESULTS The median age of WLWHIV was 44 (interquartile range [IQR], 37-50) years. Approximately 92% of the study participants preferred self-sampling at the clinic, and 90% opted to receive result notifications via mobile phone contact. The overall prevalence of Hr-HPV among study participants was 42.6%, and the most frequent Hr-HPV sub-types observed were HPV18/45 (19.1%), HPV31/35/33/52/58 (13.8%), and HPV39/68/56/66 (12.8%), followed by HPV16 (5.3%), and HPV51/59 (5.3%). WLWHIV under 35 years of age had a higher frequency of Hr-HPV compared to their older counterparts, with rates of 30% versus 11.1% (p = 0.03). The duration of antiretroviral treatment showed an inverse association with Hr-HPV negativity, with patients on treatment for 15 (IQR, 10-18) years versus 12 (IQR = 7-14) years for Hr-HPV positive patients (95% CI [1.2-5.8], t = 3.04, p = 0.003). WLWHIV with baseline CD4 T-Cell counts below 200 exhibited a higher frequency of Hr-HPV compared to those with baseline CD4 T-Cell counts above 200 (17.9% versus 1.9%, p = 0.009). However, other demographics and clinical factors, such as marital status, age of sexual debut, parity, education, history of abortion, history of preeclampsia, and cesarean delivery, did not influence the distribution of Hr-HPV genotypes. CONCLUSION Our findings indicate that WLWHIV under the age of 35 years old exhibited the highest prevalence of Hr-HPV infection, with HPV18/45 being the most prevalent subtype. Additionally, WLWHIV with baseline CD4 T-Cell counts below 200 showed the highest infection rates.

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
BACKGROUND A population-based cervical cancer screening programme is implemented in the Czech Republic. However, participation is insufficient among women over 50 years. This study aimed to estimate the potential improvement in participation through directly mailed HPV self-sampling kits (HPVssk) compared with standard invitation letters in women aged 50-65 non-participating in screening. METHODS The study recruited 1564 eligible women (no cervical cancer screening in the last 3 years or more, no previous treatment associated with cervical lesions or cervical cancer). Eight hundred women were mailed with an HPVssk (HPVssk group), and 764 women were sent a standard invitation letter (control group) inviting them to a routine screening (Pap test). The primary outcome was a comparison of the overall participation rate between study groups using a binominal regression model. RESULTS The participation rate in the HPVssk group was 13.4% [95% confidence interval (CI) 11.2-15.9%; 7.4% of women returned the HPVssk and 6.0% attended gynaecological examination] and 5.0% (95% CI 3.6-6.8%) in the control group. Using the binominal regression model, the difference between the groups was estimated as 7.6% (95% CI 5.0-10.2%; P < 0.001). In the HPVssk group, 22% of women who returned HPVssk had a positive result and 70% of them underwent a follow-up examination. CONCLUSIONS Compared with traditional invitation letters, the direct mailing of the HPVssk achieved a significantly higher participation rate, along with a notable HPV positivity rate among HPVssk responders. This approach offers a potentially viable method for engaging women who have not yet attended a cervical screening programme.

Whittaker M, Davies JC, Sargent A, Sawyer M, Crosbie EJ. A comparison of the carbon footprint of alternative sampling approaches for cervical screening in the UK: A descriptive study. BJOG 2024; 131:699-708. [PMID: 38012840 DOI: 10.1111/1471-0528.17722] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/29/2023] [Revised: 10/25/2023] [Accepted: 11/02/2023] [Indexed: 11/29/2023]
Abstract
OBJECTIVE To understand whether self-sampling can reduce carbon emissions (CO2 e) from the NHS cervical screening programme (NHSCSP) by comparing the carbon footprint of three sampling strategies: routine cervical sampling, vaginal self-sampling and first-void (FV) urine collection. DESIGN Descriptive study. SETTING National Health Service (NHS), United Kingdom (UK). POPULATION OR SAMPLE Patients aged 25-64 years eligible for cervical screening in the UK. METHODS A carbon footprint analysis was undertaken for three cervical screening sampling approaches, from point of invitation to screening through to preparation for transport to the laboratory for HPV testing. A combination of primary and secondary data were used, with a bottom-up approach applied to collection of primary data. MAIN OUTCOME MEASURES We report CO2 e per sampling approach, which is the unit used to express carbon footprint and harmonise the contributions of greenhouse gases with different global warming potentials. RESULTS The total carbon footprint of routine cervical sampling is 3670 g CO2 e. By comparison, vaginal self-sampling had a total carbon footprint of 423 g CO2 e, and FV urine sampling 570 g CO2 e. The largest share of emissions for routine sampling was attributable to the carbon footprint associated with an appointment in a primary care setting, which totalled 2768 g CO2 e. CONCLUSIONS Routine cervical sampling is up to 8.7-fold more carbon-intensive than self-sampling approaches with equivalent effectiveness. We found negligible differences in the carbon footprint of alternative self-sampling methods, supporting the need for an informed choice of screening options for participants, which includes sharing information on their environmental impacts.

Microbiol Spectr 2024; 12:e0287223. [PMID: 38323823 PMCID: PMC10913526 DOI: 10.1128/spectrum.02872-23] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/18/2023] [Accepted: 01/02/2024] [Indexed: 02/08/2024] Open
Abstract
This study assessed the accuracy of high-risk human papillomavirus testing of BD Onclarity HPV (Onclarity) assay on vaginal self-collected FLOQSwab versus cervical samples to ensure similar accuracy to detect cervical intraepithelial neoplasia. Testing was performed on two automated platforms, BD Viper LT and BD COR, to evaluate the effect of machine and using two vaginal self-samples to analyze the influence of collection, transport, and freezing-unfreezing on the results. A cervical sample and two self-samples were collected from 300 women. The first collected vaginal and the cervical sample were tested on BD Viper LT, and the second swab was frozen and subsequently tested on both automated systems. Test results on vaginal and cervical specimens were considered the index and comparator, respectively; colposcopy and histology were reference standards. Relative sensitivity for ≥CIN2 on vaginal samples analyzed versus the cervical sample was 1.01 (0.97-1.06), 1.01 (0.97-1.06), and 1.00 (0.95-1.05), for the first, second self-collected sample tested on BD VIPER LT, and second self-collected sample tested on BD COR, respectively. Relative specificity was 0.83 (0.73-0.94), 0.76 (0.67-0.87), and 0.82 (0.73-0.92) using the three different workflows. Cut-off optimization for human papillomavirus (HPV) positivity defined at Ct ≤38.3 for HPV16, ≤ 34.2 for HPV18, and ≤31.5 for all other types showed an increased relative specificity with similar sensitivity. No significant difference was observed between self-samples tested with the two platforms and between first- and second-collected swabs. Onclarity assay on FLOQSwab using both platforms showed similar sensitivity but lower specificity to detect ≥CIN2 compared to cervical samples. By cut-off optimization, non-inferior specificity could be reached. IMPORTANCE Human papillomavirus (HPV) testing on self-collected vaginal samples has been shown to improve women's participation to cervical cancer screening programs, particularly in regions with limited access to health care. Nevertheless, the introduction of self-sampling in cervical cancer screening programs requires prior clinical validation of the HPV assay in combination with a self-sample collection device, including also the laboratory workflow and automation required for high-throughput testing in screening. In this study, the performance of BD Onclarity HPV on FLOQSwab-collected vaginal self-samples has been compared to clinician-taken liquid-based cytology samples, to detect high-grade cervical intraepithelial neoplasia using two high-throughput platforms, BD Viper LT and BD COR. The study findings have shown a similar performance of BD Onclarity on testing self-collected samples, confirming the validation of the proposed pre-analytical and analytical protocols for their use in cervical cancer screening programs based on self-collected vaginal samples.

[PMID: 38103276 DOI: 10.1016/j.puhe.2023.11.026] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/03/2023] [Revised: 11/07/2023] [Accepted: 11/14/2023] [Indexed: 12/19/2023]
Abstract
OBJECTIVES Organisation of a screening programme influences programme resilience to a disruption as COVID-19. Due to COVID-19, the Dutch human papillomavirus-based cervical screening programme was temporarily suspended. Afterwards, multiple measures have been taken to catch-up participation. This study aimed to investigate programme resilience by examining the effect of COVID-19 and programme measures taken on participation in cervical screening. STUDY DESIGN Observational cohort study. METHODS Data from the national screening registry and Dutch nationwide pathology databank (Palga) were used on invitations and follow-up in 2018/2019 (pre-COVID) and 2020 (COVID). Sending invitations, reminders and self-sampling kits were suspended from March to July 2020. Main outcome measures include distribution of participant characteristics (age, region and screening history), participation rates by age and region, time between invitation and participation (i.e. response time) and self-sampling use per month. RESULTS Participation rate was significantly lower in 2020 (49.8%) compared to 2018/19 (56.8%, P < 0.001), in all ages and regions. Compared to 2018/19, participation rates decreased most in women invited from January to March 2020 (-6.7%, -9.1% and -10.4%, respectively). From August, participation rates started to recover (difference between -0.8% and -2.7%). Median response time was longer in February and March (2020: 143 and 173 days; 2018/19: 53 and 55 days) and comparable from July onwards (median difference 0-6 days). Self-sampling use was higher in 2020 (16.3%) compared to 2018/19 (7.6%). CONCLUSIONS The pandemic impacted participation rates in the Dutch cervical screening programme, especially of women invited before the programme pause. Implementation of self-sampling in national cervical screening programmes could increase participation rates and could serve as an alternative screening method in times of exceptional health care circumstances, such as a pandemic. Due to the well-organised programme and measures taken to catch-up participation, the impact of COVID-19 on the screening programme remained small.

Abstract
Objective Cervical cancer screening coverage remains low in many countries worldwide. Self-sampling approach for cervical cancer screening has a good potential to improve the screening coverage. This study aims to compare different types of HPV self-sampling devices for cervical cancer screening to identify the most accurate and acceptable device(s). Methods A systematic review was performed on data extracted from all studies specific to HPV self-sampling devices by searching relevant articles in PubMed, Google Scholar, Scopus, Web of Science, ScienceDirect, Cochrane Library, and EBSCO published from 2013 to October 2023. The study was registered in PROSPERO (CRD42022375682). Results Overall, 70 papers met the eligibility criteria for this systematic review and were included in the analysis: 22 studies reported self-sampling devices diagnostic accuracy, 32 studies reported self-sampling devices acceptability and 16 studies reported both (accuracy and acceptability). The most popular self-sampling devices were Evalyn Brush, FLOQ Swab, Cervex-Brush, and Delphi Screener. Out of overall 38 studies analyzing self-sampling devices' diagnostic accuracy, 94.7% of studies reported that self-collected specimens provided sensitivity and specificity comparable with clinician-collected samples; acceptability of Evalyn Brush, FLOQ Swab, Delphi Screener, and Colli-Pee, varied between 84.2% and 100%. Conclusion The self-sampling approach has a good potential to increase cervical cancer screening coverage. Evalyn Brush, Cervex-Brush, FLOQ Swab, and Delphi Screener self-sampling devices for HPV detection were the most commonly utilized and found to be the most accurate, and patient-acceptable. HPV detection accuracy using these self-sampling devices had no significant difference compared to the sampling performed by healthcare providers.

Abstract
BACKGROUND Primary human papillomaviruses (HPV) cervical cancer screening can be strengthened by offering home-collection of biological specimen as a valuable option to increase screening coverage. As recommended by World Health Organization (WHO), screening programs should consider whether the inclusion of HPV self-sampling as a complementary option within their existing screening algorithms could address the gaps in current coverage. However, few HPV screening tests are validated for self-sampling according to international guidelines. This study aimed to test a self-sampling-based screening strategy, complementary to the main screening program based on clinician-collected cervical samples. The study took place in Trieste, Italy, and it aimed to evaluate the feasibility of self-testing at home under an opt-in system during COVID-19 pandemic in order to exploit self-sampling to reduce the screening delay generated by the lockdown. METHODS 500 women, who should have received the screening call in 2020, were asked, via phone call, to participate in the study. To whom agreed, a home-collection kit, including a vaginal dry swab for specimen collection, was sent. The recipients performed the sample self-collection and sent back the swab through traditional mail using a prepaid envelope. Once received by the hospital, the samples were analyzed with HPV Selfy (Ulisse BioMed, Italy), a CE-IVD HPV screening test specifically validated for self-collection. Results were further compared using cobas® 4800 HPV (Roche, Switzerland). RESULTS 80% women sent back their swab, showing one of the highest return rate obtained in comparable studies. 34 HPV-positive women were followed up and underwent the Pap test, that revealed 8 low squamous intraepithelial lesions (LSIL) cases, later triaged to colposcopy. HPV Selfy was confirmed to be an adequate test for self-sampling-based screening. CONCLUSIONS This study further confirmed the feasibility of self-test at home screening strategy based on self-sampling with an opt-in system as a support method to enhance cervical cancer screening coverage in Italy. Enrolled women showed a high appreciation for this approach. HPV Selfy test demonstrated to be a valuable assay for cervical cancer screening based on home self-collection.

Cost-utility and budget impact analyses of cervical cancer screening using self-collected samples for HPV DNA testing in Thailand. BMC Public Health 2023; 23:2413.

Abstract
INTRODUCTION Cervical cancer ranks as the third most prevalent cancer among women in Thailand. However, the effectiveness of cervical cancer screening programs is limited by several factors that impede the screening rate. The utilization of self-collected samples for screening purposes has the potential to alleviate barriers to screening in Thai women. This study assessed the cost-utility and budget impact of implementing cervical cancer screening using self-collected samples for human papillomavirus (HPV) deoxyribonucleic acid (DNA) testing in Thailand. MATERIALS AND METHODS We employed a decision tree integrated with a Markov model to estimate the lifetime costs and health benefits associated with the cervical cancer screening program for women aged 25-65. The analysis was conducted from a societal perspective. Four screening policy options were compared: (1) additional self-collected samples for HPV DNA testing, (2) clinician-collected samples for HPV DNA testing only, (3) clinician-collected samples for cytology test (i.e., status quo), and (4) no screening. The model inputs were based on unvaccinated women. The screening strategies and management in those with positive results were assumed followed to the Thai clinical practice guideline. Costs were reported in 2022 Thai baht. Sensitivity analyses were conducted. The ten-year budget impacts of the additional self-collected samples for HPV DNA testing were calculated from a payer perspective. RESULTS All screening policies were cost-saving compared to no screening. When comparing the additional self-collected samples for HPV DNA testing with the clinician-collected samples policy, it emerged as the dominant strategy. The incremental benefit in cervical cancer prevention achieved by incorporating self-collected samples for screening was observed at any additional screening rate that could be achieved through their use. Sensitivity analyses yielded consistently favorable results for the screening policies. The average annual budget impact of the additional self-collected samples for screening policy amounted to 681 million Thai baht. This budget allocation could facilitate cervical cancer screening for over 10 million women. CONCLUSIONS An addition of self-collected samples for HPV DNA testing into the cervical cancer screening program is cost-saving. The benefits of this screening policy outweigh the associated incremental costs. Policymakers should consider this evidence during the policy optimization process.

Abstract
OBJECTIVES Optimally, cancer is diagnosed through periodic screening or detection of early symptoms in primary care settings. However, an estimated 23%-52% of gastrointestinal (GI) cancers are diagnosed in the emergency department (ED). Cancer diagnosed in the ED has been associated with worse clinical and patient-reported outcomes even after adjustment for cancer stage. We sought to explore patients' accounts of patient and health care system factors related to their diagnosis in the ED and their lived experience of receiving a diagnosis in this setting. METHODS Patients with an ED visit during or within 30 days of their GI cancer diagnosis at an urban academic hospital serving a largely disadvantaged population were recruited. Interviews were coded in NVivo 12 and analyzed using a thematic analysis approach. RESULTS Patient-reported factors associated with their experiences included denial and avoidance of symptoms, mistrust of the health system, and lack of cancer screening knowledge. Health care system factors included misdiagnosis and delayed access to specialty care or tests. Experiences receiving a cancer diagnosis in the ED were overwhelmingly negative. CONCLUSIONS This study highlights the unmet needs in identifying and diagnosing patients who ultimately present to the ED for evaluation and eventual diagnosis of cancer. Our results shed light on several modifiable factors, including the need for increased public awareness of the asymptomatic nature of cancer and the importance of cancer screening. Additionally, health care systems modifications beyond the ED are needed to improve access to timely care when symptoms arise.

Glinska P, Komerska K, Janik B, Olkowicz J, Jedrzejewska I, Macios A, Wieszczy P, Kaminski MF, Arbyn M, Nowakowski A. HPV testing in Polish population-based cervical cancer screening programme (HIPPO project)-study protocol of a randomised healthcare policy trial. BMC Cancer 2023; 23:1118. [PMID: 37978452 PMCID: PMC10655392 DOI: 10.1186/s12885-023-11597-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/29/2022] [Accepted: 10/31/2023] [Indexed: 11/19/2023] Open
Abstract
BACKGROUND An Organised Cervical Cancer Screening Programme (OCCSP) was started in Poland in 2006/2007. Each woman aged 25 to 59 is eligible for a free Pap test every 3 years in OCCSP. Despite implementation of the OCCSP, the age-standardised cervical cancer (CC) incidence and mortality rates in 2019 were 7.3/100 000 and 3.9/100 000 respectively and were still higher than those in Western European countries with well-organised screening programmes. Apart from low coverage of the OCCSP, suboptimal performance of the screening test (conventional cytology) may be partially responsible for this situation. Several countries have already incorporated high risk Human Papillomavirus (hrHPV) testing in CC screening as a more sensitive tool reducing the risk of missing precancerous lesions and allowing for extension of screening intervals. The European Guidelines for Quality Assurance in Cervical Cancer Screening recommend pilot evaluation of a new screening test in country-specific conditions before its implementation. METHODS The HIPPO project (HPV testing In Polish POpulation-based cervical cancer screening program) is a randomised health services study nested in the OCCSP in Poland. The project will randomise 33 000 women aged 30-59 years to cytology or hrHPV testing (ratio: 1:1) with age stratification. In the cytology arm women with repeated Atypical Squamous Cells of Undetermined Significance (ASC-US) or ≥ Low-Grade Squamous Intraepithelial Lesions (LSIL) are referred for colposcopy. In the other arm, hrHPV ( +) women with ≥ ASC-US reflex Liquid-Based Cytology (LBC) are referred for colposcopy. Primary endpoints include detection rates of histologically confirmed high grade intraepithelial lesions or worse (CIN2 +) in each arm. DISCUSSION This pilot randomised healthcare study nested in the OCCSP in Poland will assess and compare the performance of hrHPV testing to current standard-cytology in order to make decisions on implementation of HPV-based screening in the country. TRIAL REGISTRATION This randomised healthcare service study was prospectively registered at https://clinicaltrials.gov/ (identifier: NCT04111835, protocol ID 28/2019) on 19th of September 2019.

Abstract
BACKGROUND To compare the triage performance of HPV viral loads reflected by cycle threshold values (CtV) from two different HPV testing assays: the PCR based Cobas4800 and the isothermal amplification based AmpFire assay. METHODS We used the data from a sub-study of The Chinese Multi-Center Screening Trial and analyzed the data of the cases positive in both Cobas4800 and AmpFire assays with recorded CtV. Spearman's correlation was applied to analyze the association between CtV from AmpFire and Cobas4800 assays, as well as the correlation between CtV and the histological lesion grades. The 50th percentile of CtV was used as the cutoff to construct triage algorithms for HPV-positive cases. McNemar's test was used to analyze the differences in sensitivity and specificity for detecting CIN2 + and CIN3 + in different triage algorithms. RESULTS Four hundred forty-six HPV positive women who had consistent HPV results from Cobas4800 and AmpFire in terms of the HPV genotype and reported Ct values were included in the analysis. The mean CtV of hrHPV tested by Cobas4800 and AmpFire were linear correlated. Direct association were showed between the severity of cervical lesions and the HPV viral loads reflected by CtV of hrHPV, HPV16, non-16/18 hrHPV and A9 group from both assays. HPV16/18 genotyping combined with low-CtV for non-16/18 hrHPV, especially A9 group, were demonstrated to be satisfactory in the sensitivity and specificity for detecting CIN2 + or CIN3 + . CONCLUSION Ct value represented a good triage marker in both PCR-based and isothermal amplification HPV detection.

Abstract
Background The COVID-19 pandemic led to reductions in cervical cancer screening and colposcopy. Therefore, in this mixed method study we explored perceived pandemic-related practice changes to cervical cancer screenings and colposcopies. Methods In 2021, a national sample of 1251 clinicians completed surveys, including 675 clinicians who performed colposcopy; a subset (n=55) of clinicians completed qualitative interviews. Results Nearly half of all clinicians reported they were currently performing fewer cervical cancer screenings (47%) and colposcopies (44% of those who perform the procedure) than before the pandemic. About one-fifth (18.6%) of colposcopists reported performing fewer LEEPs than prior to the pandemic. Binomial regression analyses indicated that older, as well as internal medicine and family medicine clinicians (compared to OB-GYNs), and those practicing in community health centers (compared to private practice) had higher odds of reporting reduced screening. Among colposcopists, internal medicine physicians and those practicing in community health centers had higher odds of reporting reduced colposcopies. Qualitative interviews highlighted pandemic-related care disruptions and lack of tracking systems to identify overdue screenings. Conclusions Reductions in cervical cancer screening and colposcopy among nearly half of clinicians more than 1 year into the pandemic raise concerns that inadequate screening and follow-up will lead to future increases in preventable cancers. Funding This study was funded by the American Cancer Society, who had no role in the study's design, conduct, or reporting.

Abstract
The World Health Organization (WHO) has called for the elimination of cervical cancer as a public health problem. Cervical cancer screening through human papillomavirus (HPV) testing is a core component of the strategy for elimination, with a set target of screening 70% of women twice in their lifetimes. In this review, we discuss technical barriers and opportunities to increase HPV screening globally.

Abstract
Self-collection of samples for human papillomavirus (HPV) testing has the potential to increase the uptake of cervical screening among underscreened women and will likely form a crucial part of the WHO's strategy to eliminate cervical cancer by 2030. In high-income countries with long-standing, organised cervical screening programmes, self-collection is increasingly becoming available as a routine offer for women regardless of their screening histories, including under- and well-screened women. For these contexts, a validated microsimulation model determined that adding self-collection to clinician collection is likely to be cost-effective on the condition that it meets specific thresholds relating to (1) uptake and (2) sensitivity for the detection of high-grade cervical intraepithelial neoplasia (CIN2+). We used these thresholds to review the 'early-adopter' programme-level evidence with a mind to determine how well and how consistently they were being met. The available evidence suggested some risk to overall programme performance in the situation where low uptake among underscreened women was accompanied by a high rate of substituting clinician sampling with self-collection among well-screened women. Risk was further compounded in a situation where the slightly reduced sensitivity of self-sampling vs clinician sampling for the detection of CIN2+ was accompanied with lack of adherence to a follow-up triage test that required a clinician sample. To support real-world programmes on their pathways toward implementation and to avoid HPV self-collection being introduced as a screening measure in good faith but with counterproductive consequences, we conclude by identifying a range of mitigations and areas worthy of research prioritisation.

Identification of a methylation panel as an alternative triage to detect CIN3+ in hrHPV-positive self-samples from the population-based cervical cancer screening programme. Clin Epigenetics 2023; 15:103. [PMID: 37322534 PMCID: PMC10273737 DOI: 10.1186/s13148-023-01517-6] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/12/2023] [Accepted: 06/03/2023] [Indexed: 06/17/2023] Open
Abstract
BACKGROUND The Dutch population-based cervical cancer screening programme (PBS) consists of primary high-risk human papilloma virus (hrHPV) testing with cytology as triage test. In addition to cervical scraping by a general practitioner (GP), women are offered self-sampling to increase participation. Because cytological examination on self-sampled material is not feasible, collection of cervical samples from hrHPV-positive women by a GP is required. This study aims to design a methylation marker panel to detect CIN3 or worse (CIN3+) in hrHPV-positive self-samples from the Dutch PBS as an alternative triage test for cytology. METHODS Fifteen individual host DNA methylation markers with high sensitivity and specificity for CIN3+ were selected from literature and analysed using quantitative methylation-specific PCR (QMSP) on DNA from hrHPV-positive self-samples from 208 women with CIN2 or less (< CIN2) and 96 women with CIN3+. Diagnostic performance was determined by area under the curve (AUC) of receiver operating characteristic (ROC) analysis. Self-samples were divided into a train and test set. Hierarchical clustering analysis to identify input methylation markers, followed by model-based recursive partitioning and robustness analysis to construct a predictive model, was applied to design the best marker panel. RESULTS QMSP analysis of the 15 individual methylation markers showed discriminative DNA methylation levels between < CIN2 and CIN3+ for all markers (p < 0.05). The diagnostic performance analysis for CIN3+ showed an AUC of ≥ 0.7 (p < 0.001) for nine markers. Hierarchical clustering analysis resulted in seven clusters with methylation markers with similar methylation patterns (Spearman correlation> 0.5). Decision tree modeling revealed the best and most robust panel to contain ANKRD18CP, LHX8 and EPB41L3 with an AUC of 0.83 in the training set and 0.84 in the test set. Sensitivity to detect CIN3+ was 82% in the training set and 84% in the test set, with a specificity of 74% and 71%, respectively. Furthermore, all cancer cases (n = 5) were identified. CONCLUSION The combination of ANKRD18CP, LHX8 and EPB41L3 revealed good diagnostic performance in real-life self-sampled material. This panel shows clinical applicability to replace cytology in women using self-sampling in the Dutch PBS programme and avoids the extra GP visit after a hrHPV-positive self-sampling test.

Abstract
BACKGROUND "REACH-Bhutan" aimed to evaluate the feasibility and clinical performance of a community-based screening program for cervical cancer in rural Bhutan using self-collected samples for high-risk human papillomavirus (HR-HPV) testing. METHODS In April/May 2016, 2590 women aged 30-60 years were screened across rural Bhutan by providing a self-collected sample for careHPV testing. All careHPV-positive women, plus a random sample of careHPV-negative women, were recalled for colposcopy and biopsy. Self-samples also underwent GP5+/6+ polymerase chain reaction (PCR)-based HR-HPV DNA detection and genotyping. Cross-sectional screening indices were estimated against histological high-grade squamous intraepithelial lesions or worse (hHSIL+), including imputation of hHSIL+ in women without colposcopy. RESULTS HR-HPV positivity was 10.2% by careHPV and 14.8% by GP5+/6+ PCR. Twenty-two cases of hHSIL+ were histologically diagnosed, including one invasive cancer; an additional 7 hHSIL+ were imputed in women without colposcopy. HR-HPV testing by GP5+/6+ showed higher sensitivity for hHSIL+ (89.7%, 95% CI 72.6-97.8) than careHPV (75.9%, 95% CI 56.5-89.7). Negative predictive value was also slightly higher for GP5+/6+ (99.9%, 95% CI 99.6-100) than careHPV (99.7%, 95% CI 99.4-99.9). Specificity, however, was lower for GP5+/6+ (86.1%, 95% CI 84.6-87.4) than careHPV (90.6%, 95% CI 89.4-91.7), as was positive predictive value (6.9%, 95% CI 4.5-9.9 vs. 8.5%, 95% CI 5.4-12.6). Of 377 HR-HPV-positive women by GP5+/6+, 173 (45.9%) were careHPV-positive, including 54.7% HPV16-positive and 30.2% HPV18-positive women. CONCLUSIONS The final REACH-Bhutan results show that screening for cervical cancer with self-collection of samples and HR-HPV testing, in addition to our previous report of achieving high participation, can also perform well to detect women with hHSIL+.

Abstract
In 2017, cervical cancer screening in the Netherlands switched from cytology to human papillomavirus (HPV) testing using the validated PCR-based cobas 4800. Women could order and subsequently received a free self-sampling kit (Evalyn Brush) at their home address instead of clinician sampling. In the laboratory, the shipped brush was placed into 20 mL of PreservCyt fluid, before testing. In the first 2 years of the new program, only 7% of screening tests were performed on a self-sample. Those who chose self-sampling versus clinician sampling were more likely to have never been screened previously and differed also with respect to sociodemographic factors. Subsequent more active promotion and increasing the ease to obtain kits increased the proportion opting for self-sampling (16% in 2020). HPV positivity and detection rate of precancer (CIN3+) were lower in the self-sampling compared with the clinician-sampling group (adjusted ORs of 0.65 and 0.86, respectively). Although population differences may partially explain these results, self-samples may have been too dilute, thereby reducing the analytic and clinical sensitivity. The Dutch findings demonstrate the importance of optimizing outreach, specimen handling and testing protocols for self-samples to effectively screen the target population and reach in particular the women at highest risk for cervical cancer.

Cancer Epidemiol Biomarkers Prev 2023; 32:91-97. [PMID: 36620897 PMCID: PMC9833840 DOI: 10.1158/1055-9965.epi-22-0793] [Citation(s) in RCA: 9] [Impact Index Per Article: 9.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/15/2022] [Revised: 09/13/2022] [Accepted: 10/31/2022] [Indexed: 01/10/2023] Open
Abstract
BACKGROUND Through adequate screening and follow-up, cervical cancer can be prevented or detected at early-stage (stage I), which is related to excellent survival. Current guidelines recommend discontinuing screening for women ≥65 years with history of normal Pap and/or HPV tests, potentially leaving this age group vulnerable. This study examined late-stage disease in a population-based cohort. METHODS Using California Cancer Registry data, we identified 12,442 patients ages ≥21 years with a first primary cervical cancer diagnosed during 2009-2018. Proportions of late-stage disease (stages II-IV) and early- and late-stage 5-year relative survival are presented by the age group. Among patients ages ≥65 years, multivariable logistic regression estimated associations of sociodemographic and clinical characteristics with late-stage cervical cancer. RESULTS Nearly one fifth of patients (n = 2,171, 17.4%) were ≥65 years. More women ages ≥65 years (71%) presented with late-stage disease than younger women (48% in patients ages <65). Late-stage 5-year relative survival was lower for women ≥65 years (23.2%-36.8%) compared with patients <65 (41.5%-51.5%). Characteristics associated with late-stage cervical cancer in women ≥65 years included older age [odds ratio (OR), 1.02; 95% confidence interval (CI), 1.01-1.04; each year], non-adenocarcinoma histologic subtypes, and comorbidities (OR, 1.59; 95% CI, 1.21-2.08). CONCLUSIONS There remains a significant burden of advanced cervical cancer in women ≥65. IMPACT Efforts should be made to better understand how the current screening paradigm is failing women of 65 years and older. Future work should focus on determining past screening history, lapses in follow-up care, and non-invasive testing approaches.

Clinical Performance of the RealTi me High Risk HPV Assay on Self-Collected Vaginal Samples within the VALHUDES Framework. Microbiol Spectr 2022; 10:e0163122. [PMID: 36047900 PMCID: PMC9602690 DOI: 10.1128/spectrum.01631-22] [Citation(s) in RCA: 7] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/15/2022] [Accepted: 07/08/2022] [Indexed: 12/31/2022] Open
Abstract
The VALHUDES framework (NCT03064087) was established to evaluate the clinical accuracy of HPV testing on self-samples compared with HPV testing on matched clinician-taken cervical samples. Women referred to colposcopy due to previous cervical abnormalities were recruited at five Belgian colposcopy centers. A total of 486 pairs of matched cervical samples and vaginal self-samples were included in the analysis (228 collected with Evalyn Brush and 258 with Qvintip). The dry vaginal brushes were transferred into 20 mL ThinPrep PreservCyt solution. All specimens were tested with the Abbott RealTime High Risk HPV assay (Abbott RT). Testing on vaginal and cervical specimens was considered the index and comparator tests, respectively, and colposcopy and histology as the reference standard. The clinical sensitivity for CIN2+ of Abbott RT (cutoff ≤32 cycle number [CN]) on vaginal self-samples (Evalyn Brush and Qvintip combined) was 8% lower than on the cervical clinician-collected samples (ratio = 0.92 [95% CI, 0.87 to 0.98]), while the specificity was similar (ratio = 1.04 [95% CI, 0.97 to 1.12]). Sensitivity (ratio = 0.95 [95% CI, 0.89 to 1.02]) and specificity (ratio = 1.11 [95% CI, 0.995 to 1.23]) on Evalyn Brush samples was similar to cervical, while on Qvintip samples, the sensitivity was 12% lower than cervical samples (ratio = 0.88 [95% CI, 0.78 to 0.998]) with similar specificity (0.99 [95% CI, 0.90 to 1.10]). Exploratory cutoff optimization (cutoff ≤35 CN) resulted in an improvement of the relative sensitivity (self-sampling versus clinician sampling: ratio = 0.96 [95% CI, 0.91 to 1.02]) but yielded a loss in relative specificity (ratio = 0.92 [0.85 to 1.00]). The clinical accuracy of Abbott RT differed from the self-sampling device. However, after cutoff optimization, the sensitivity on self-samples taken with either of two vaginal brushes became similar to clinician-collected samples. IMPORTANCE Self-samples are becoming a crucial part of HPV-based cervical cancer screening programs to reach nonattendee women and increase screening coverage. Therefore, the VALHUDES framework was established to validate and evaluate HPV tests and devices on self-samples. Here, in the present manuscript, we evaluated the accuracy of the RealTime High Risk HPV assay (Abbott RT) on two different vaginal devices to detect cervical intraepithelial neoplasia grade two or higher (CIN2+). The study results demonstrated that the Abbott RT assay is similarly accurate on vaginal self-samples as on matched clinician-taken cervical samples after adjusting cutoff values. Moreover, we observed that some vaginal devices perform better than others in CIN2+ detection. We also underline the necessity of standardization and validation of general workflow and sample handling procedures for vaginal self-samples.

Comparison of self-collected versus clinician collected cervicovaginal specimens for detection of high risk human papillomavirus among HIV infected women in Ethiopia. BMC Womens Health 2022; 22:360. [PMID: 36050660 PMCID: PMC9434869 DOI: 10.1186/s12905-022-01944-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/19/2022] [Accepted: 08/22/2022] [Indexed: 12/02/2022] Open
Abstract
Background In order to meet the WHO 2030 cervical cancer elimination program, evaluation and utilization of sensitive testing method, and feasible sampling technique is a paradigm for enhancing cervical cancer screening coverage. Self-sampling for screening of HPV DNA testing is one of the easiest and sensitive techniques, though the evidence was limited in the Ethiopian context. This study aimed to compare the performance of self-collected vaginal specimen versus clinician collected cervical specimen for detection of HPV among HIV positive women in Ethiopia.
Methods We conducted a comparative cross-sectional study design to collect cervicovaginal specimens among HIV positive women of age older than 24 years. Data were collected from six government hospitals from January to October 2021. A total of 994 cervicovaginal specimens was collected by clinicians and HIV positive women themselves in the cervical cancer screening unit using Abbott Cervi-Collect Specimen Collection Kit, and molecular HPV testing was conducted. Data were entered into an Excel spreadsheet and analyzed using SPSS version 25. Sensitivity, specificity and kappa were reported with p < 0.05 considered as statistically significant.
Results The prevalence of high-risk HPV was 29.4% among self-sampled specimen and 23.9% among clinician collected specimens. The overall concordance of the test result was 87.3%. Oncogenic HPV types, other than HPV16&18 were predominant in both sampling techniques, 19.9% from vaginal self-collected specimen and 16.7% of clinician collected cervical specimens. The sensitivity and specificity of self-sampled HPV test was 84.0% and 88.4%, respectively. The level of agreement was good (k = 0.68) and statistically significant (p < 0.001). The discriminatory power of the test as true positive and negative was excellent with an area under the curve of 0.86. Conclusion The magnitude of oncogenic HPV was higher in self-collected samples than the clinician collected specimen with good agreement between the two sampling methods. Thus, we recommend the Ministry of Health in Ethiopia to expand utilization of the self-sampled technique and enhance the coverage of screening in the country.

Abstract
(1) Background: Low patient’s adherence to conventional cervical cancer screening methods determined the need to take into consideration alternative approaches, and vaginal HPV self-sampling is one of them. We aimed to evaluate, using an online survey, the Romanian women’s acceptability of vaginal HPV self-sampling. (2) Methods: A 13-questions online survey was distributed on three Facebook groups, and the results were summarized. (3) Results: Despite of good educational background, 10.8% (n = 60) of the respondents did not know what a Pap smear is, and 33% (n = 183) were not informed about the free national cervical cancer screening program. Multivariate analysis revealed an increased likelihood of vaginal self-sampling acceptance among respondents who did not know about Pap test (OR: 7.80; 95%CI: 1.062−57.431; p = 0.021), national cervical cancer screening program (OR: 1.96; 95%CI: 1.010−3.806; p = 0.02), HPV infection (OR: 7.35; 95%CI: 3.099−17.449; p< 0.001) or HPV test (OR: 1.67; 95%CI: 0.950−2.948; p = 0.03). Moreover, women who did not previously undergo a cervical cancer screening program were more likely to accept the new screening method (OR: 1.62; 95%CI: 0.878−3.015; p = 0.04). (4) Conclusions: Our results showed high acceptability rates of vaginal HPV self-sampling among participants.

Abstract
Objective To calculate the changes in harms and benefits of cervical cancer screening over the first three screening rounds of the Dutch high‐risk human papillomavirus (hrHPV) screening programme. Design Microsimulation study. Setting Dutch hrHPV screening programme; women are invited for screening every 5 or 10 years (depending on age and screening history) from age 30 to 65. Population Partly vaccinated population of 100 million Dutch women. Methods Microsimulation model MISCAN was used to estimate screening effects. Sensitivity analyses were performed on test characteristics and attendance. Main outcome measures Harms (screening tests, unnecessary referrals, treatment‐related health problems), benefits (CIN2+ diagnoses) and programme efficiency (number needed to screen [NNS]) over the first (period 2017–2021), second (period 2022–2026) and third (period 2027–2031) rounds of hrHPV‐based screening. Results The number of screening tests and CIN2+ diagnoses decreased from the first to the second round (−25.8% and −23.6%, respectively). In the third screening round, these numbers decreased further, albeit only slightly (−2.7% and −5.3%, respectively). NNS to detect a CIN2+ remained constant over the rounds; however, it increased in younger age groups while decreasing in older age groups. Conclusion Both harms and benefits of hrHPV screening decreased over the first screening rounds. For younger women, the efficiency would decrease, whereas longer screening intervals would lead to increased efficiency in older women. Programme efficiency overall remained stable, showing the importance of longer intervals for low‐risk women. Tweetable abstract: Cervical cancer screening: both harms and benefits of hrHPV screening will decrease in the future. Cervical cancer screening: both harms and benefits of hrHPV screening will decrease in the future.

Abstract
Cervical cancer is a major public health problem, especially in the north region of Brazil. The aim of the study was to identify the factors associated with not undergoing the cervical cancer screening test in rural riverside populations in the Amazon. A cross-sectional home-based survey was carried out in 38 locations covered by a fluvial primary healthcare team, and the administrative records of the screening tests from January 2016 to May 2019 were analyzed. After the descriptive analysis, logistic regression was performed considering the outcome of having undergone cervical cancer screening within the past three years. Of the 221 women assessed, 8.1% had never undergone the test, and 7.7% had undergone it more than three years ago. Multiparity (OR = 0.76 (95%CI = 0.64-0.90)), occupation in domestic activities (OR = 0.31 (95%CI = 0.11-0.89)), and lack of knowledge of the healthcare unit responsible for the service (OR = 0.18 (95%CI = 0.04-0.97)) were associated with not undergoing the cervical cancer screening test. The administrative records revealed that the screening test was performed outside the recommended age range (24%), performed needlessly (9.6%) with undue repetitions (3.2%), and a high percentage of the samples collected were unsatisfactory (23.5%). The findings revealed the existence of barriers for riverside women to access cervical cancer screening tests.

Effects of Menstrual Cycle on the Accumulation of Human Papillomavirus-Infected Cells Exfoliated from the Cervix That Drift into the Vagina. Microorganisms 2022; 10:microorganisms10040693.

Abstract
Human papillomavirus (HPV) testing using self-collected vaginal specimens is the preferred choice to increase screening uptake. Although the HPV testing results of these samples depend on the cells that naturally exfoliate from the cervical lesion and drift into the vagina, the mechanism of when and how these exfoliated cells mix with the self-collected sample remains unclear. Hence, the study aimed to clarify the relationship between the vaginal drift of HPV-infected cells exfoliated from the cervix, and the menstrual cycle. A total of 180 scraped samples of the cervix and vagina were examined. The exfoliated cells were classified into two categories according to the HPV genotyping results of each sample: sufficient accumulation (same HPV types in cervical and vaginal samples) and insufficient accumulation (fewer HPV types in vaginal samples than in cervical samples, or HPV positivity in cervical samples and HPV negativity in vaginal samples). A moderately strong statistically significant association was observed between exfoliated cell accumulation and the menstrual cycle, and insufficient accumulation was statistically significantly increased at the early proliferative phases. Self-collection of vaginal samples at the early proliferation phase indicates insufficient sample quantities or lower viral load, thereby affecting HPV genotyping.

Explaining Correlates of Cervical Cancer Screening among Minority Women in the United States. PHARMACY 2022; 10:pharmacy10010030.

Abstract
Globally, cervical cancer is the fourth leading cause of death among women. While overall cervical cancer rates have decreased over the last few decades, minority women continue to be disproportionately affected compared to White women. Given the paucity of theory-based interventions to promote Pap smear tests among minority women, this cross-sectional study attempts to examine the correlates of cervical cancer screening by Pap test using the Multi-theory Model (MTM) as a theoretical paradigm among minority women in the United States (U.S.). Structural Equation Modelling (SEM) was done for testing the construct validity of the survey instrument. Data were analyzed through bivariate and multivariate tests. In a sample of 364 minority women, nearly 31% (n = 112) of women reported not having received a Pap test within the past three years compared to the national rate (20.8%) for all women. The MTM constructs of participatory dialogue, behavioral confidence, and changes in the physical environment explained a substantial proportion of variance (49.5%) in starting the behavior of getting Pap tests, while the constructs of emotional transformation, practice for change, and changes in the social environment, along with lack of health insurance and annual household income of less than $25,000, significantly explained the variance (73.6%) of the likelihood to sustain the Pap test behavior of getting it every three years. Among those who have had a Pap smear (n = 252), healthcare insurance, emotional transformation, practice for change, and changes in the social environment predicted nearly 83.3% of the variance in sustaining Pap smear test uptake behavior (adjusted R2 = 0.833, F = 45.254, p < 0.001). This study validates the need for health promotion interventions based on MTM to be implemented to address the disparities of lower cervical cancer screenings among minority women.
