ABSTRACT
OBJECTIVES: To examine the associated risk of cervical intraepithelial neoplasm grade 3+ (CIN3+) lesions in patients with AGC and extensive human papillomavirus (HPV) genotyping. METHODS: Cases with atypical glandular cell (AGC) interpretation on a Papanicolaou (Pap) test were identified along with associated extensive HPV genotyping and histologic follow-up results. RESULTS: Within this cohort of 469,694 Pap tests, 0.4% were diagnosed as AGCs. In total, 1267 cases had concurrent high-risk HPV (hrHPV) genotyping, and 40.3% were hrHPV positive. The percentage of AGC cases with cervical CIN3+ on histologic follow-up was 52.2% when hrHPV was positive, whereas it was 4.9% with a negative hrHPV result. The top 5 hrHPV genotypes associated with cervical CIN3+ in this cohort were HPV16, HPV18, HPV58, HPV52, and HPV33. Indeed, 92.8% of the hrHPV-associated CIN3+ lesions identified in this cohort were positive for at least one of these HPV genotypes. The sensitivity of detecting cervical CIN3+ lesions was 85.6% with the top 5 hrHPV genotypes (HPV16/18/58/52/33) and only increased to 89.0% when the additional 12 genotypes were included. CONCLUSIONS: In patients with an AGC Pap, the risk of having a cervical CIN3+ lesion is greatly increased by positivity for hrHPV types 16, 18, 58, 52, and/or 33. Incorporating comprehensive HPV genotyping into AGC cytology allows for refined risk stratification and more tailored management strategies.
ABSTRACT
Advances in whole-slide imaging and artificial intelligence present opportunities for improvement in Pap test screening. To date, there have been limited studies published regarding how best to validate newer AI-based digital systems for screening Pap tests in clinical practice. In this study, we validated the Genius™ Digital Diagnostics System (Hologic) by comparing the performance to traditional manual light microscopic diagnosis of ThinPrep® Pap test slides. A total of 319 ThinPrep® Pap test cases were prospectively assessed by six cytologists and three cytopathologists by light microscopy and digital evaluation and the results compared to the original ground truth Pap test diagnosis. Concordance with the original diagnosis was significantly different by digital and manual light microscopy review when comparing across: (i) exact Bethesda System diagnostic categories (62.1% vs 55.8%, respectively, pâ¯=â¯0.014), (ii) condensed diagnostic categories (76.8% vs 71.5%, respectively, pâ¯=â¯0.027), and (iii) condensed diagnoses based on clinical management (71.5% vs 65.2%, respectively, pâ¯=â¯0.017). Time to evaluate cases was shorter for digital (Mâ¯=â¯3.2â¯min, SDâ¯=â¯2.2) compared to manual (Mâ¯=â¯5.9â¯min, SDâ¯=â¯3.1) review (t(352)â¯=â¯19.44, pâ¯<â¯0.001, Cohen's dâ¯=â¯1.035, 95% CI [0.905, 1.164]). Not only did our validation study demonstrate that AI-based digital Pap test evaluation had improved diagnostic accuracy and reduced screening time compared to light microscopy, but that participants reported a positive experience using this system.
ABSTRACT
BACKGROUND: The United States (U.S.) has a growing population of Brazilian immigrant women. However, limited research has explored Pap tests and human papillomavirus (HPV) vaccination among this population. METHODS: Participants completed an online survey between July-August 2020. Bivariate analyses examined associations between healthcare-related variables (e.g., insurance, having a primary care provider) and demographics (e.g., age, education, income, marital status, years living in the U.S., primary language spoken at home) with 1) Pap test recency (within the past 3 years) and 2) HPV vaccination (0 doses vs. 1 + doses). Variables significant at p < 0.10 in bivariate analyses were included in multivariable logistic regression models examining Pap test recency and HPV vaccination. RESULTS: The study found that 83.7% of the sample had a Pap test in the past three years. Women who did not know their household income were less likely to be than women who reported a household income of < $25,000 (adjusted OR [aOR] = 0.34, 95% CI: 0.12, 0.95). Women who had seen a healthcare provider in the past year were more likely to have had a Pap test within the last three years than those who had not seen a provider in the past year ([aOR] = 2.43, 95% CI: 1.32, 4.47). Regarding HPV vaccination, 30.3% of respondents reported receiving one or more doses of the HPV vaccine. The multivariable logic regression models determined that women aged 27 -45 (aOR = 0.35, 95% CI: 0.18, 0.67) were less likely than women aged 18-26 to have been vaccinated against HPV). and that women with a PCP were more likely to be vaccinated than those without a PCP (aOR = 2.47. 95% CI:1.30, 4.59). CONCLUSION: This study found that Brazilian immigrant women in the youngest age groups (21 - 29) for Pap test, 18- 26 for HPV vaccination) had somewhat better rates of Pap screening and HPV vaccination than the general U.S. POPULATION: This study adds new information about cervical cancer prevention and control behaviors among Brazilian immigrant women.

Background: Despite the availability of effective vaccines, human papillomavirus (HPV) vaccine uptake remains low in most resource-limited settings including Nigeria. Mobile health technology (mHealth) may empower patients to control their health, reduce inequalities, and improve the uptake of HPV vaccination. Aim: The "mHealth-HPVac" study will assess the effects of mHealth using short text messages on the uptake of HPV vaccination among mothers of unvaccinated girls aged 9-14 years and also determine the factors influencing the uptake of HPV vaccination among these mothers. Methods: This protocol highlights a randomised controlled trial involving women aged 25-65 years who will be enrolled on attendance for routine care at the General Outpatient clinics of Lagos University Teaching Hospital, Lagos, Nigeria between July and December 2024. At baseline, n=224 women will be randomised to either a short text message or usual care (control) arm. The primary outcome is vaccination of the participant's school-age girl(s) at any time during the 6 months of follow-up. The associations between any two groups of continuous variables will be tested using the independent sample t-test (normal distribution) or the Mann-Whitney U test (skewed data) and that of two groups of categorical variables with Chi-square (X2) or Fisher's exact test where appropriate. Using the multivariable binary logistic regression model, we will examine the effects of all relevant sociodemographic and clinical variables on HPV vaccination uptake among mothers of unvaccinated but vaccine-eligible school-age girls. Statistical significance will be defined as A P<0.05. Discussion: The mHealth-Cervix study will evaluate the impact of mobile technologies on HPV vaccination uptake among mothers of unvaccinated but vaccine-eligible school-age girls in Lagos, Nigeria as a way of contributing to the reduction in the wide disparities in cervical cancer incidence through primary prevention facilitated using health promotion to improve HPV vaccination uptake.

ABSTRACT
BACKGROUND: Despite the availability of effective vaccines, human papillomavirus (HPV) vaccine uptake remains low in most resource-limited settings including Nigeria. Mobile health technology (mHealth) has the potential to empower patients to manage their health, reduce health disparities, and enhance the uptake of HPV vaccination. AIM: The "mHealth-HPVac" study will assess the effects of mHealth using short text messages on the uptake of HPV vaccination among mothers of unvaccinated girls aged 9-14 years and also determine the factors influencing the uptake of HPV vaccination among these mothers. METHODS: This protocol highlights a randomised controlled trial involving women aged 25-65 years who will be enrolled on attendance for routine care at the General Outpatient clinics of Lagos University Teaching Hospital, Lagos, Nigeria between July and December 2024. At baseline, n = 123 women will be randomised to either a short text message or usual care (control) arm. The primary outcome is vaccination of the participant's school-age girl(s) at any time during the 6 months of follow-up. The associations between any two groups of continuous variables will be assessed using the independent sample t-test for normally distributed data, or the Mann-Whitney U test for skewed data. For two groups of categorical variables, the Chi-square (X2) test or Fisher's exact test will be used, as appropriate. Using the multivariable binary logistic regression model, we will examine the effects of all relevant sociodemographic and clinical variables on HPV vaccination uptake among mothers of unvaccinated but vaccine-eligible school-age girls. Statistical significance will be reported as P < 0.05. DISCUSSION: The mHealth-Cervix study will evaluate the impact of mobile technologies on HPV vaccination uptake among mothers of unvaccinated but vaccine-eligible school-age girls in Lagos, Nigeria as a way of contributing to the reduction in the wide disparities in cervical cancer incidence through primary prevention facilitated using health promotion to improve HPV vaccination uptake.

BACKGROUND: Pitfalls in Pap test could be defined as false positive, false negative, or underdiagnosed results which can lead to unnecessary diagnostic procedures or delayed and inadequate treatment. It can be a consequence of misinterpretation of certain morphological entities which are described in this paper. SUMMARY: The paper presents an overview of the morphological features and look-alikes of the common sources of pitfalls such as atrophy, repair, intrauterine device change, tubal metaplasia, hyperchromatic crowded groups, and radiation changes. Rare causes of pitfalls such as Arias-Stella changes, pemphigus, tumor diathesis per se, rare types of cervical cancer, including verrucous and papillary squamous cell cancer, gastric type, and endometrioid adenocarcinoma are also described. KEY MESSAGES: The awareness of pitfalls in cervical cytology is important for cytopathologists and clinicians to avoid future errors. Review of Pap tests with erroneous diagnosis is important for quality control in cytology laboratory, and it must be considered an educational- and experience-building procedure. Cytopathologist should not pull back in significant diagnoses, especially in human papillomavirus-negative cases.

BACKGROUND: A cytologic diagnosis of atypical squamous cells, cannot exclude high-grade squamous lesion (ASC-H) poses a disproportionately high risk of cervical cancer development. The objective of this study was to analyze type-specific risks by mapping human papillomavirus (HPV) genotypes in ASC-H cytology. METHODS: In total, 1,048,581 Papanicolaou tests that had ASC-H cytology were retrieved. Concurrent HPV genotyping using proprietary multiplex real-time (MRT) and polymerase chain reaction (PCR) HPV tests and histologic follow-up findings were analyzed. RESULTS: Among 1678 patients who had ASC-H findings (0.16%), 1414 (84.3%) underwent concurrent HPV genotyping (MRT, 857; HPV PCR test, 557). The overall high-risk HPV (hrHPV)-positive rate was 84.4%. Of the 857 MRT cases, 63.9% were infected with a single hrHPV, and 24.4% had multiple genotypes. The most prevalent HPV types were HPV16/52/58/33/31. Lesions that were identified as cervical intraepithelial neoplasia 2 or worse (CIN2+) were detected in 498 of 906 cases (55.0%), including 81 cervical carcinomas (8.9%). The risk of CIN2+ for the composite group of HPV16/52/58/33/31-positive cases was 62.7%, representing 90.7% (264 of 291) of total CIN2+ lesions in ASC-H/hrHPV-positive cases by MRT. CIN2+ lesions were detected in 108 of 142 (76.1%) HPV16-positive and/or HPV18-positive women by the PCR the HPV test. Among 128 hrHPV-negative ASC-H cases by both methods, CIN2+ lesions were identified in 21 of 128 (16.4%), including five cervical carcinomas (3.9%). The sensitivity, specificity, positive predictive value, and negative predictive value for patients in the composite group with HPV16/52/58/33/31 were 88.0%, 40.8%, 62.7%, and 75.0%, respectively. CONCLUSIONS: Papanicolaou tests classified as ASC-H are associated with a high CIN2+ rate and warrant colposcopy, regardless of HPV status. The extent to which the risk-stratification provided by comprehensive HPV genotyping can inform the management of ASC-H cytology remains to be explored.
ABSTRACT
BACKGROUND: The earliest cytotechnologists are largely unknown. SUMMARY: In 1943, the book "Diagnosis of Uterine Cancer by the Vaginal Smear" by Papanicolaou and Traut recognized several women who have largely faded from memory. While Mary Papanicolaou and Charlotte Street are familiar names, others like Alberta Kuder and Huldah Boerker, who inadvertently laid the groundwork for the field of cytotechnology, remain obscure. There were also women like Christine Rassias and Adele Reboul who did not receive recognition. Notably, Mrs. Lady Mary G. Papanicolaou, despite her significant contributions both in the lab and at home since 1914, was not acknowledged in her husband's work until the publication of his Atlas in 1954. KEY MESSAGE: These women set the benchmark for future cytotechnologists, unknowingly shaping the profession as we know it today.
ABSTRACT
Human papilloma virus (HPV) infection and its progression still represent a great medical challenge worldwide. Clinical evidence has demonstrated the beneficial effects of polyhexamethylene biguanide (PHMB) on HPV clinical manifestations; however, evidence of the effect of this molecule on HPV viral load is still lacking. In this in vitro study, 13 ThinPrep Papanicolaou (Pap) tests were treated with a PHMB solution (0.10 g/100 mL) for 2 h. We observed no cytological changes but a significant reduction in the viral load of high-risk (HR) HPV after PHMB treatment, also revealing a dose-dependent antiviral effect. In addition, by stratifying the obtained results according to HR-HPV genotype, we observed a significant reduction in the viral load of HPV 16, P2 (56, 59, 66), 31, and P3 (35, 39, 68) and a strong decrease in the viral load of HPV 45, 52, and P1 (33, 58). Overall, 85% of the analyzed cervical cell samples exhibited an improvement in HPV viral load after PHMB exposure, while only 15% remain unchanged. For the first time, the data from this pilot study support the activity of PHMB on a specific phase of the HPV viral lifecycle, the one regarding the newly generated virions, reducing viral load and thus blocking the infection of other cervical cells.
ABSTRACT
BACKGROUND: Cervical cancer is the fourth most common cancer among women worldwide, both for incidence and mortality. Prevention relies on screening with a Pap test to detect precancerous lesions, which can then be treated. Access to this screening is currently both improvable and inequitable. Pregnancy may be an ideal moment for women to catch up on their overdue cervical cancer screening. In the general population, women's risk of not being screened is associated with their place of birth and other social factors; this may be true as well among pregnant women. Our objective was to study the association between women's place of birth and their failure to catch up with this screening during pregnancy. METHODS: The 2016 French National Perinatal Survey included 13,147 women who gave birth after 21 weeks of gestation. The association between their place of birth and failure to catch up on this screening (defined by the absence of a Pap test during pregnancy for women overdue for it) was adjusted for age, parity, education level, health insurance, and when they began prenatal care with logistic regression models. RESULTS: Among the women for whom screening was then recommended, 49% were not up to date at the start of pregnancy, and of these, 53% were not caught up before delivery. After adjustment for other risk factors, maternal place of birth was not associated with a higher risk of failure to catch up with this screening during pregnancy. However, factors identified as associated with this risk included a low education level and late start of prenatal care. CONCLUSION: About half of women overdue for cervical cancer screening did not catch up with it during their pregnancy. Professionals should pay special attention to women with lower education levels and late initiation of prenatal care, who constitute a group at high risk of not catching up on this screening during pregnancy.

Introduction: cervical cancer is a health concern worldwide. The South Kivu Province in the Eastern DR Congo is facing many cases of this disease but poorly screened and reported. The objective of this was to determine the prevalence of cell abnormalities at cervical cytology in a tertiary teaching hospital in Bukavu and their association with common risk factors of cervical cancer. Methods: a cross-sectional study was conducted on 142 women attending the Provincial Referral Hospital of Bukavu (HPGRB) from February to December 2021. Quantitative variables were described by their median following their asymmetric distributions and the qualitative variables in absolute and relative frequencies. Then the Chi-square test was used for the comparison of proportion. Results: forty-five percent of the participants had between three and five children. Twenty-two (15.5%) of the 142 patients reported to have two or more sexual partners and 17.5% reported the use of hormonal contraception. The prevalence of cell abnormalities at cervical cytology was 17% of which Low- Grade Squamous Intraepithelial Lesion (LSIL) was the most representative (12.9%). There was no statistically significant association between the common cervical risk factors and the occurrence of cell abnormalities. Conclusion: cervical pre-cancerous lesions are frequent in South Kivu province. The Pap smear test remains an early and affordable screening method and constitutes a secondary prevention strategy in women of 18 years and older in a low-income country such as DR Congo where vaccination against HPV is still hypothetic.

INTRODUCTION: Atypical glandular cells (AGC) represent less than 1% of Pap test cases and include a variety of lesions in both the cervix and endometrium. The study aimed to investigate the cytology-histology correlation in AGC patients and to evaluate the clinical utility of hrHPV testing in this diagnostic context. MATERIALS AND METHODS: We identified 491 atypical glandular cells (AGC) cases in our quality analysis (QA) database of 336,064 Pap tests interpreted between March 1, 2013 and July 12, 2016. Of these, 251 cases had follow-up biopsies with hrHPV tests in 148 cases. RESULTS: The most common histologic diagnosis associated with AGC was normal/benign or low-grade lesions, comprising 55% of cervical biopsies and 24% of endometrial biopsies. High-grade lesions were identified in 21% of follow-up biopsies. In patients with AGC cytology, a positive hrHPV test significantly increased the likelihood of cervical HSIL or above lesions on biopsy by 26.4 times (OR = 26.4, 95% CI: 5.8-119.4, P < 0.0001). A positive genotyping result for HPV 16 dramatically increased the likelihood of cervical HSIL or above lesions on biopsy (OR = 84, 95% CI: 12.0-590.5, P < 0.0001). The HPV test had a negative predictive value of 97% (CI: 85%-100%). CONCLUSIONS: Our study confirms that AGC is a significant diagnosis with an overall risk for high-grade cervical or endometrial lesions as high as 21%. hrHPV testing with genotyping is an effective tool for identifying high-risk individuals within the AGC population, with excellent positive and negative predictive values. This approach is valuable for clinical risk stratification and differential diagnosis in patients with AGC cytology.

BACKGROUND: Cervical cancer is the ninth diagnosed cancer among Saudi women. The majority of cervical cancer cases occur in women who did not undergo screening. However, the screening rates in several countries, including Saudi Arabia, remain suboptimal. It is important to identify the factors associated with the uptake of screening and predictors of screening in order to increase the uptake rate. AIM: To determine the factors associated with the uptake of cervical cancer screening among family medicine physicians (FMPs), compared with women of the community. METHODS: This was a cross-sectional study conducted in the central region (Riyadh), Kingdom of Saudi Arabia from February 2021 for 12 months on female physicians and women of the community. An electronic questionnaire was used to investigate the demographics of women and variables related to the uptake of screening. RESULTS: A total of 126 FMP and 127 women from the community were included. The factors affecting screening among FMP included age (P=0.013), health insurance (P=0.002), availability of Pap smear (PË0.001), and physician encouragement (PË0.001). The factors affecting the screening of community women included the availability of Pap smears (PË0.001) and physician encouragement (PË0.001). Multivariate analysis revealed that physician encouragement of Pap smear was a significant predictor of screening among FMP (OR=8.26, PË0.001) and community women (OR=6.67, PË0.001). The perceived benefit was the only predictor for screening among FMP (OR=0.75, P=0.004). CONCLUSION: The uptake of cervical cancer screening was higher in the community women. The factors linked to the uptake differed among the two groups, but the support of doctors played a significant role in the likelihood of uptake, regardless of the group of women. It is recommended to enhance the guidance of medical personnel in recommending screening during clinic visits for the specific target group. Additionally, there should be increased education on the significance of screening and efforts to educate the community about cervical cancer and screening.
ABSTRACT
BACKGROUND: High HIV prevalence, and lack of organized screening for the indigent population receiving care and treatment within HIV clinics in low-resource settings increases cervical cancer incidence. We sought to determine predictors of cervical precancer in women living with HIV and receiving cervical cancer screening in Jos, Nigeria. METHODS: A cross-sectional study of women living with HIV and receiving care and treatment in adult HIV/AIDS clinics in Jos-Metropolis, Nigeria between June 2020 and April 2023. Ethical approvals were obtained from the ethics committee in Jos, Nigeria and Northwestern University IRB, USA. Informed consent was obtained from eligible participants, and data on socio-demographics, cancer risk factors, and cytology reports were collected. The outcome variables were cervical precancer lesions. The independent variables were prior Pap smear status, socio-demographics, income, educational, and other reproductive health factors. Descriptive statistics was done to obtain means ± sd, frequencies, and percentages for the variables. Univariate and bivariate analyses were done to determine predictors of cervical dysplasia. Analyses were performed using R software. RESULTS: Of 957 women screened, 570 were living with HIV and 566 women had cytology report and were included in the final analysis. The mean age was 45.08 ± 8.89 years and 81.6% had no prior evidence of Pap test (under-screened). Prevalence of cervical dysplasia was 24% (mild and severe dysplasia were 12.9% and 11.1%, respectively). Age above 45 years (aOR = 3.48, p = 0.009), postmenopausal status (aOR = 7.69, p = 0.000), and women with no history of prior IUCD use (aOR = 5.94, p = 0.0001), were predictors for severe dysplasia. Women who had history of STI (aOR = 0.17, p = 0.000), prior use of IUCD (aOR = 0.32, p = 0.004), prior use of condom (aOR = 2.50, p = 0.003) and had co-morbidities (aOR = 0.46, p = 0.009) were more likely to have had a Pap test in the past. CONCLUSIONS: The majority of indigent women receiving care at HIV clinics had their first Pap test screening, and lack of organized screening among older and post-menopausal women with HIV, puts women at a higher risk of developing severe cervical precancer lesions.

Prior research has found that women with disabilities have often experienced disparities in receipt of cervical cancer screening. However, there is a research gap regarding receipt of cervical cancer screening by types of disability. This study examined the differences in receiving cervical cancer screening through self-reported Pap testing among women by disability type. This cross-sectional study analyzed data from the 2016, 2018, and 2020 Behavioral Risk Factor and Surveillance System (BRFSS). The relative risk of cervical cancer screening through self-reported Pap tests received within the past three years among women aged 21-65 by disability type was compared using modified Poisson regression with robust error variance. A total of 307,142 women from across the USA were sampled. In every disability group, older women were significantly less likely to receive Pap tests than their counterparts without disabilities. Women with multiple disabilities (aRR=0.91; 95% CI, 0.89-0.94) and those with ambulatory disabilities (aRR=0.93; 95% CI, 0.91-0.97) reported being less likely to receive Pap tests than women with no disability. Ambulatory disability and multiple disabilities are associated with a lower likelihood of cervical cancer screening with Pap test, increasing the need to eliminate disability-specific disparities in Pap testing. Future efforts should focus on improving cancer education programs tailored to the needs of women with disabilities, addressing barriers related to mobility and access to healthcare services, and ensuring equitable access to preventive screenings.

Cervical cytology has been an integral part of cervical cancer screening since the mid-20th century with the implementation of screening protocols utilising Pap testing. During that time, cervical cancer has gone from the leading cause of cancer deaths in women to not even appearing in the top 10 causes of US cancer deaths. However, despite its long and widespread use, cervical cytology remains a diagnostically challenging area in the practice of cytopathology. Of particular importance for diagnosticians is the accurate diagnosis of high-grade squamous intraepithelial lesions (HSILs), given the significant risk of progression to invasive cervical cancer and the importance to patient management. Therefore, this review is presented in order to highlight the diagnostic features of HSIL, its various appearances, and important benign and neoplastic differential considerations with an emphasis on morphological clues that can aid in distinguishing between these different processes.

According to the Center for Disease Control and Prevention's National Breast and Cervical Cancer Early Detection Program, the cervical cancer screening rate dropped by 84% soon after the declaration of the COVID-19 pandemic. The challenges facing cervical cancer screening were largely attributed to the required in-person nature of the screening process and the measures implemented to control the spread of the virus. While the impact of the COVID-19 pandemic on cancer screening is well-documented in high-income countries, less is known about the low- and middle-income countries that bear 90% of the global burden of cervical cancer deaths. In this paper, we aim to offer a comprehensive view of the impact of COVID-19 on cervical cancer screening in LMICs. Using our study, "Prevention of Cervical Cancer in India through Self-Sampling" (PCCIS), as a case example, we present the challenges COVID-19 has exerted on patients, healthcare practitioners, and health systems, as well as potential opportunities to mitigate these challenges.
ABSTRACT
The human papillomavirus (HPV) carries a significant health risk for people with a cervix. Among transgender and nonbinary people, however, testing and treatment for HPV can pose difficulties, and even be traumatic at times. This current study is part of a larger mixed methods study conducted in Michigan in 2020, and it explores the experiences of transmasculine and nonbinary people with at-home self-swabbing HPV test kits and knowledge of HPV transmission/screenings. Phenomenological methods were used by conducting virtual qualitative interviews with ten transmasculine and nonbinary individuals with cervixes, ages 23-59. Interviews were independently coded by members of the research team and a tabletop theming method was used. Four themes were generated from the data: 1) Multilevel barriers; 2) "Get it done, so I know that I am safe"; 3) Contrasting preferences for care; and 4) Community calls for change. The discussion focuses on the implications of these findings for improving sexual health care for the transgender and nonbinary community, along with directions for further research.
