HPV self-collection for cervical cancer screening among survivors of sexual trauma: a qualitative study.

Intimate partner violence affects 20-30% of women in the United States. Disparities in routine cervical cancer surveillance have been demonstrated in certain populations, including victims of intimate partner violence (IPV). This study examined and assessed the acceptability of high-risk HPV (hrHPV) self-collection among individuals who have experienced IPV. We conducted an observational study using qualitative data collection and analysis. We interviewed individuals with a history of IPV and who currently reside in Oregon. This study identified key themes describing knowledge and attitudes towards cervical cancer screening for individuals who have experienced IPV. They include: guideline knowledge, prior office-based cervical cancer screening experience, barriers to cervical cancer screening, at-home hrHPV self-collection experience, and testing confidence. Participants experienced fewer barriers and expressed increased comfort and control with hrHPV self-collection process. Individuals with a history of IPV have lower rates of cervical cancer screening adherence and higher rates of cervical dysplasia and cancer than other populations. The patient-centered approach of hrHPV self-collection for cervical cancer screening can reduce barriers related to the pelvic exam and empower patients to reduce their risks of developing cervical cancer by enabling greater control of the testing process.

Assessment of psychological distress in patients with cervical dysplasia according to age, education, information acquisition and information level.

PURPOSE: This study aims to investigate the psychological distress experienced by patients with an initial diagnosis of abnormal Pap smears or dysplastic changes of the cervix uteri. It investigated whether patients' age, education, information level and approach to information acquisition have an impact on their psychological distress. METHODS: A total of 364 female patients, aged 20-80 years, referred to the special dysplasia consultation hour at the Department of Obstetrics and Gynecology, Wuerzburg, completed a questionnaire containing validated items to assess information level, information acquisition, information needs and psychological distress, including a distress thermometer. Data from questionnaires and medical reports were used for analysis. RESULTS: The study found that 56.9% of patients experienced psychological distress before their first visit. Patients under 44 years of age, especially those with concerns about fertility and sexuality, and those with lower levels of education showed higher levels of distress (p-value = 0.018 and p-value = 0.037). 40.9% of patients felt poorly informed and 53.7% of patients wanted more information before their visit. Correlational analysis showed that the method of obtaining information correlated with the desire for more information (p-value < 0.001). Those who received information via the Internet felt less informed, wanted more information and experienced more anxiety. CONCLUSION: These findings highlight the need for improved patient education strategies and effective doctor-patient communication to address the knowledge gap and reduce patient distress. In addition, healthcare providers should ensure that patients have access to reliable online resources for accurate information.

Enhancing cervical cancer cytology screening via artificial intelligence innovation.

A double-check process helps prevent errors and ensures quality control. However, it may lead to decreased personal accountability, reduced effort, and declining quality checks. Introducing an artificial intelligence (AI)-based system in such scenarios could effectively address the risk of oversights. This study introduces an innovative AI-integrated workflow for cervical cytology screening that substantially improves efficiency and reduces the burden on cytologists. The AI model prioritizes cases for review based on anomaly scores and streamlines the first screening process to approximately 10 s per case. The model enhances the identification of high-risk cases via detailed microscopic observation, high anomaly scores cases, and a targeted review of low-score cases. The workflow highlights its capability for rapid, accurate, and less labor-intensive evaluations, demonstrating the potential to transform cervical cancer screening. This study highlights the importance of AI in modern medical diagnostics, particularly in areas with a high demand for accuracy and efficiency.

Enhancing equity in cervical screening - initiatives to increase screening participation.

PURPOSE OF REVIEW: Cervical cancer can be eliminated as a public health problem through a three-pillar approach including high coverage of human papillomavirus (HPV) vaccination and HPV-based cervical screening, and treatment of precancers and invasive cancers. However, access inequities prevent many women and people with a cervix benefitting from these life-saving advances. This review focuses on evidence-based interventions that can improve equity and scale-up of cervical screening. RECENT FINDINGS: The transition from conventional cytology to HPV screening provides multiple opportunities to address equity and a multipronged approach can be used to identify priority groups, understand barriers and develop tailored solutions. There are proven financing mechanisms, tools, technologies and screening delivery methods to overcome screening barriers in different settings. This includes self-sampling interventions, point-of-care testing, health service integration, consumer-led co-design processes and digital screening registries. SUMMARY: To achieve cervical cancer elimination globally, cervical screening must be delivered in an inclusive, culturally safe and context-appropriate manner. There are multiple tools and strategies that can be implemented to improve participation of never- and under-screened groups, and to enhance equity in cervical screening.

The association between affordable care act implementation and the prevalence of women having ever received a Pap smear.

BACKGROUND: To assess if implementation of the 2010 Patient Protection and Affordable Care Act (ACA) was associated with changes in the prevalence of women having ever received a pap smear. METHODS: This study utilised the publicly available Centre for Disease Control National Survey of Family Growth (NSFG) data set. This was a serial cross-sectional study. The comparison groups were defined as women who received cancer screening and prevention interventions prior to full implementation of the ACA (2011-2013) and post full implementation (2017-2019). The primary outcome was self-reporting receipt of a Papanicolaou (Pap) smear. Secondary outcomes included HPV vaccination and mammogram rates. Anonymized patient information was collected from the nationally representative dataset, and analyses were performed utilising STATA 18. RESULTS: The two study cohorts obtained from the NSFG included women who responded in 2011-2013 (n = 5601), deemed to be 'Pre-ACA implementation' (Pre ACA), and those who responded in 2017-2019 (n = 6141) 'Post-ACA implementation' (Post ACA). The proportion of women who were 21 years and older and ever had a Pap smear in the Pre ACA group (96.0%) was higher than that of the Post ACA group (94.1%) (OR 0.66 (0.49-0.91)). In contrast, HPV vaccination rates rose, and mammogram rates remained stable in the Post ACA period. CONCLUSION: A decrease in proportion of women ever having had a Pap smear despite implementation of health policies to increase access to preventive measures suggests further interventions to improve access to cervical cancer screening are warranted.

The Patient Protection and Affordable Care Act, which was implemented in 2014, aimed to reform health care access. This serial cross-sectional study demonstrated that the number of women age 21 or older who had ever received a pap smear fell after the implementation of the Patient Protection and Affordable Care Act.

High-risk human papillomavirus infection and cervical cytopathology: relationship with cervical nitric oxide levels.

BACKGROUND: Nitric oxide (NO) may contribute to the persistence of high-risk human papillomavirus (hrHPV) infection, which has been linked to the development of premalignant lesions and cervical cancer. Our study aimed to examine the relationship between cervical NO metabolite (NOx) levels, hrHPV infection, and cytopathological findings. Additionally, we assessed cervical NOx levels as a biomarker for predicting hrHPV infection and epithelial atypia. METHODS: The study involved 74 women who attended the Gynecology and Obstetrics outpatient clinics at Cairo University Hospitals between November 2021 and August 2022. Cervical samples were subjected to Pap testing, assessment of NOx levels by the Griess method, and detection of hrHPV DNA by real-time polymerase chain reaction. RESULTS: High-risk HPV was detected in 37.8% of women. EA was found in 17.1% of cases, with a higher percentage among hrHPV-positive than negative cases (35.7% vs. 4.3%, p = 0.001). The most prevalent hrHPV genotype was HPV 16 (89.3%). The cervical NOx level in hrHPV-positive cases was significantly higher (37.4 µmol/mL, IQR: 34.5-45.8) compared to negative cases (2.3 µmol/mL, IQR: 1.2-9.8) (p = < 0.001). Patients with high-grade atypia showed significantly higher NOx levels (38.0 µmol/mL, IQR: 24.6-94.7) in comparison to NILM and low-grade atypia cases (5.0 µmol/mL, IQR: 1.6-33.3 and 34.5 µmol/mL, IQR: 11.7-61.7, respectively) (p = 0.006). Although the NOx levels among hrHPV-positive cases with low-grade atypia (40.4 µmol/mL, IQR: 33.3‒61.8) were higher than those with NILM (36.2 µmol/mL, IQR: 35.7‒44.0) and high-grade atypia (38.0 µmol/mL, IQR: 24.6‒94.7), the difference was not significant (p = 0.771). ROC curve analysis indicated that the cervical NOx cut-off values of > 23.61 µmol/mL and > 11.35 µmol/mL exhibited good diagnostic accuracy for the prediction of hrHPV infection and EA, respectively. CONCLUSIONS: The high prevalence of hrHPV infection, particularly HPV 16, in our hospital warrants targeted treatment and comprehensive screening. Elevated cervical NOx levels are associated with hrHPV infection and high-grade atypia, suggesting their potential use as biomarkers for predicting the presence of hrHPV and abnormal cytological changes.

Knowledge and awareness of cervical cancer and human papillomavirus vaccination among female university students.

BACKGROUND:  Prevention strategies for reducing cervical cancer incidence rely on informed populations, particularly those most at risk. This study assesses the knowledge and awareness of female university students towards cervical cancer, human papillomavirus (HPV) and its vaccination. METHODS:  A validated self-administered questionnaire was used in a descriptive cross-sectional study among female university students. The data were analysed with Statistical Package for Social Sciences version 26, and p  0.05 was considered significant. RESULTS:  The total participants were 190 with a mean age of 22.6 ± 4.35 years. The majority (90%) were aware of cervical cancer, and 78.9% agreed it is a terminal illness, but fewer participants knew it was associated with infection (63.7%), and that it had effective risk-reducing methods (70.5%). Only 32.6% were aware of the Pap smear test, less than half (43.2%) were aware of the cervical cancer vaccine and only 43.7% knew it was available locally. Although fewer (39.5%) considered themselves susceptible to cervical cancer, many (62.1%) would like a Pap smear test. Overall, 88.9% of the participants possessed adequate knowledge of cervical cancer, 67.9% of the HPV vaccine and only 33.7% of HPV. Ethnicity (p = 0.03), year of study (p = 0.001) and institution (p = 0.002) were all significantly associated with knowledge levels, vaccine awareness and Pap smear test awareness. CONCLUSION:  Participants showed low HPV knowledge and varying awareness levels regarding cervical cancer, HPV and HPV vaccine.Contribution: This study provides insights into female university students' knowledge and awareness gaps, highlighting the need for targeted interventions.

Randomized experimental population-based study to evaluate the acceptance and completion of and preferences for cervical cancer screening.

Cervical cancer has high incidence and mortality rates, especially in less-developed countries. Prevention methods are well established, but there are still barriers preventing some Brazilian women from undergoing a Pap sample. The objective of the study was to evaluate the acceptance, preferences and completion of four screening methods. This has an experimental design (community trial). A total of 164 participants who had never had a Pap sample or had not had one for more than three years were included. The city's urban area was stratified by census tracts and divided according to income and education levels. Women belonging to the lower-income strata were considered in the study. Random blocks were numbered into five intervention groups (Group 1- Pap sample at the hospital; Group 2- Pap sample in the mobile unit; Group 3- urine self-collection; Group 4- vaginal self-collection; Group 5- woman's choice). Only 164 women met all of the eligibility criteria (15.3%). Most of them accepted the assigned method (92%), but only 84% of the women completed the collection step. The acceptance rates were as follows: Group 1 (100%), Group 2 (64.5%), Group 3 (100%) and Group 4 (91.4%). In Group 5, the women's preferences were distributed as follows: examination performed at the hospital, 13 women (33.3%); examination performed at the mobile unit, 11 women (28.2%); urine self-collection, 11 women (28.2%); and vaginal self-collection, 4 women (10.3%). This study suggests that methods that allow cervical sampling collected near the women's domicile might improve the acceptance and completion of preventive tests. This finding is relevant for the development of new cervical cancer screening strategies.

Are we ready for human papillomavirus testing? Assessment of patient knowledge of and preferences for cervical cancer screening in Ontario.

OBJECTIVE: To determine patient knowledge and preferences about primary human papillomavirus (HPV) testing. DESIGN: Cross-sectional survey. SETTING: Two family practice clinics (urban and suburban) and the social media platforms of 2 hospitals in the greater Toronto area between January and February 2023. PARTICIPANTS: A total of 413 Ontario residents aged 25 to 69 years, with a cervix, who qualified for Papanicolaou (Pap) screening and could communicate in English. METHODS: Electronic survey containing questions about knowledge of, and preferences for, cervical cancer screening, including types of screening and screening intervals, and about education related to HPV and screening intervals. MAIN FINDINGS: Of 441 potential participants, 426 were eligible and consented to participate in the study; ultimately 413 provided completed or partially completed surveys (96.9% response rate). Of those who completed a recent Pap test, 57.8% (208 of 360) knew of HPV testing. Initially, 27.8% thought HPV testing was better than Pap testing for cervical cancer screening. After learning HPV tests exist and have self-sampling options, most participants preferred HPV testing (self-sampling 46.3%, provider sampling 34.1%). Annual cervical cancer screening was preferred by 50.1% of participants despite knowing that, for most people, Pap tests should be conducted every 3 years (74.8%). After learning about HPV testing, participants were more likely to prefer 5-year screening intervals (43.8%); however, those in the family practice group were still more likely to prefer 3-year intervals compared with those in the social media group (P<.01). CONCLUSION: Participants in this study identified a preference for HPV testing and self-sampling options. Concerns were raised about extended screening intervals and the safety of self-collected samples that need to be addressed in public health education initiatives during rollout of new screening programs.

DYNAMICS OF HPV GENOTYPES AND THE RESULTS FOUND IN CYTOLOGICAL LESIONS OF UNIVERSITY STUDENTS: A COMPARATIVE STUDY.

The objective of this study was to evaluate the prevalence of human papillomavirus (HPV) genotypes and their relationship with different grades of cytological lesions in female students of the Faculty of Health Sciences of the National University of Chimborazo. Material and Methods: The research had a quantitative and descriptive approach, with a comparative analysis of HPV genotypes and cytological lesions in students of the Faculty of Health Sciences. It is an experimental and field study, cross-sectional and retrospective, conducted from November 2023 to March 2024. Thirty students were selected by quota sampling, analyzing conventional cytology and data using SPSS 26. The results showed that 75.8% of the samples had Bethesda Negative results, whereas 24.2% had some degree of cytological lesion (ASC-US 13.7%, L-SIL 8.1%, H-SIL 1.6%, and ASC-H 0.8%). Genotyping showed the high prevalence of HPV, with HPV 18 and 33 being the most common high-risk genotypes. The most common low-risk indicators were HPV 43 and 42. Conclusions: The study confirmed the high prevalence of HPV among female university students and established a significant correlation between high-risk genotypes and the presence of more severe cytological lesions. These findings underscore the need for interventions aimed at prevention and early treatment of HPV, especially in high-risk populations.

HPV specificity and multiple infections and association with cervical cytology in Chongqing, China: a cross-sectional study.

BACKGROUND: It is important to assess the relationship between specific HPV genotype or multiple infection and cervical cytology. The protection provided by the HPV vaccine is type-specific, and the epidemiology feature of coinfections needs to be investigated. The aim is to provide baseline information for developing HPV vaccination and management of HPV-positive populations in the region. METHODS: A total of 3649 HPV-positive women were collected from 25,572 women who underwent 15 HR-HPV genotypes and ThinPrep cytologic test (TCT) results. Logistic regression was used to determine the correlation between the risk of cytology abnormalities and specific HPV infection. We calculated odds ratios (ORs) to assess coinfection patterns for the common two-type HPV infections. chi-squared test was used to estimate the relationship between single or multiple HPV (divided into species groups) infection and cytology results. RESULTS: The results showed there was a positive correlation between HPV16 (OR = 4.742; 95% CI 3.063-7.342) and HPV33 (OR = 4.361; 95% CI 2.307-8.243) infection and HSIL positive. There was a positive correlation between HPV66 (OR = 2.445; 95% CI 1.579-3.787), HPV51 (OR = 1.651; 95% CI 1.086-2.510) and HPV58(OR = 1.661; 95% CI 1.166-2.366) infection and LSIL. Multiple HPV infections with α9 species (OR = 1.995; 95% CI 1.101-3.616) were associated with a higher risk of high-grade intraepithelial lesions (HSIL) compared with single HPV infection. There were positive correlations between HPV66 and HPV56 (α6) (OR = 3.321; 95% CI 2.329-4.735) and HPV39 and HPV68 (α7). (OR = 1.677; 95% CI 1.127-2.495). There were negative correlations between HPV52, 58, 16 and the other HPV gene subtypes. CONCLUSION: HPV33 may be equally managed with HPV16. The management of multiple infections with α9 may be strengthened. The 9-valent vaccine may provide better protection for the population in Chongqing currently. The development of future vaccines against HPV51 and HPV66 may be considered in this region.

The role of endocervical curettage in the diagnosis of cervical intraepithelial neoplasia in human papillomavirus positive patients.

BACKGROUND: The role of endocervical curettage (ECC) in the diagnosis of cervical intraepithelial neoplasia (CIN) is a controversial topic. OBJECTIVES: Investigate the role of ECC in the diagnosis of CIN in human papillomavirus (HPV) positive patients. DESIGN: Retrospective. SETTING: A tertiary training and research hospital. PATIENTS AND METHODS: This study included patients who were referred for colposcopy between 2018-2022 because of abnormal screening results. ECC results, age, cytology, HPV status, and colposcopic impression of the patients were extracted from the medical records. Multinomial logistic regression analyses were performed to identify factors that could predict CIN on ECC. MAIN OUTCOME AND MEASURES: The likelihood of high-grade squamous intraepithelial lesions (HSIL) in ECC in patients with cervical biopsy results of normal and low-grade squamous intraepithelial lesion (LSIL). SAMPLE SIZE: 2895 women. RESULTS: In patients with normal and LSIL cervical biopsy results, HSILs were detected in 6.7% of ECC results. There was no difference in the detection rates of CIN in ECC among groups with smear results negative for intraepithelial lesions or malignancy (NILM), atypical squamous cells of undetermined significance (ASC-US), and LSIL. The likelihood of HSIL being observed in ECC was 2.2 times higher in patients with HPV16. The probability of LSIL disanois was 2.3 times higher in women aged 50-59 years and 2.8 times higher in women ≥ 60 years compared to the reference group of <30 years. The probability of LSIL was 2.3 and HSIL by ECC was 2.2 times higher in both age categories (P<.012 and P=.032, respectively) than the reference group of <30 years. CONCLUSION: Regardless of colposcopic findings, ECC should be performed in patients with smear results of NILM who are positive for HPV16, in patients with smear results of ASC-US and LSIL who are positive for any oncogenic type of HPV and in patients 50 and above with any result of smear or any oncogenic HPV type. LIMITATIONS: We did not have the components of the HPV types in mixed groups.

Cervical cancer screening and treatment costing in Senegal.

Introduction: in Senegal, cervical cancer is the leading cause of cancers among women. This study estimated the costs associated with cervical cancer screening and treatment for precancerous lesions from the health system perspective. Methods: we estimated costs for screening, diagnostics, and treatment. We conducted a cross-sectional study in seven regions with primary data collected from 50 health facilities. Data collection included structured questionnaires, with secondary data from the Ministry of Health and other sources. A mixed-methods approach combined ingredients-based costing and financial expenditures to estimate direct medical and non-medical costs. All costs are reported in 2019 USD. Results: average costs were $3.71 for visual inspection with acetic acid, $16.49 for Pap smear, and $46.65 for human papillomavirus deoxyribonucleic acid (HPV DNA) testing. Screening cost drivers were clinical exam supplies and clinical equipment for visual inspection with acetic acid, offsite processing of specimens for Pap smear, and lab equipment costs for HPV DNA procedure. The average cost of diagnosis via colposcopy alone was $25.73, and colposcopy with biopsy/endocervical curettage was $74.96. The average cost of treatment followed by one visit for pre-cancerous lesions was $195.24 for loop electrosurgical excision, $47.35 for cryotherapy, and $32.35 for thermal ablation. Clinical equipment and lab costs were the largest contributors to colposcopy and endocervical curettage/biopsy expenses. Clinical equipment made up the largest portion of cryotherapy, loop electrosurgical excision, and thermoablation costs. Conclusion: this study is the first to estimate the costs of HPV screening and treatment in Senegal, which can be used to inform decision-making on cervical cancer investments.

Improving the effectiveness of cervical cancer screening: Managing positive high-risk human papillomavirus results.

Introduction: Good compliance of the management of abnormal results is important for effective cervical screening. This study investigated the rate of surveillance and follow-up outcomes for human papillomavirus (HPV)-positive women in cervical screening. Method: Women on surveillance by repeat HPV testing were identified in a prospectively managed database. Data retrieved included women's age, country residence status, history of colposcopy, HPV-DNA status on the first and repeat tests, dates of follow-up during the 5 years since the initial screening, and histological diagnosis of cervical lesions. The main outcome measures were compliance rate for repeat HPV testing, regression and persistence rates of HPV subtypes, and detection rate of high-grade lesions (CIN2+). Results: This analysis included 680 residents in the community, mean age 44.8 (95% confidence interval 20.1-69.5) years. The compliance rate of repeat testing was 28.2% at 12 months and, cumulatively, 42.8% for the entire 5-year follow-up period. The rates were unaffected by age (P=0.5829) nor prior colposcopy (P=0.1607). There were 5 (1.7%) cases of CIN2+ detected. Of 391 women on longitudi-nal follow-up, 194 (60.8%) cleared their HPV infection. Some women with multiple HPV infection cleared 1 but not the other subtype(s). Thus, the regression rate was 90.3% for HPV-16, 87.0% for HPV-18 and 65.2% for HPV-12-others (P=0.001). The annualised HPV regression rates were similar for HPV subtypes and for each follow-up year. Conclusion: Surveillance of HPV positivity is clinically important for detecting high-grade lesions. Despite a high regression rate of HPV, surveillance hesitancy is a serious weakness in routine cervical screening.

Validation of digital image slides for diagnosis in cervico-vaginal cytology.

OBJECTIVE: To test the diagnostic concordance between microscopic (MI) and digital (DG) observation of cervico-vaginal (CV) cytology in a validation study of the technique. METHODS: Five cytotechnologists (CT) reviewed 888 routine CV cytology cases from the Cervical Pathology Unit of our center over a 2-week period of time. The cases were first observed by MI and at the end of the day the cases were observed by DG. STATISTICAL ANALYSIS USED: Agreement calculated using the Kappa index. RESULTS: Most of the diagnoses corresponded to benign (64%) or inflammatory conditions (14%) and 24% corresponded to the intraepithelial lesion or malignancy (ILM) category. The overall kappa coefficient of concordance was strong (0.87). Among the different CTs it was almost perfect in two, strong in two and moderate in one. In 18 cases (10%) there were discrepancies between techniques in the category of ILM. In 10 (56%) cases there was an overdiagnosis in DG and in 8 (44%) an overdiagnosis in MI. Only in two cases, the diagnostic discrepancy exceeded one degree of difference between lesions, and they were ASCUS or AGUS for DG and CIN 2 for MI. CONCLUSIONS: In this validation test in which routine cases during a two-week period have been used, observing the cases with both techniques on the same day, we have obtained a strong degree of concordance. The discordances obtained have not been considered relevant.

Attitude to cervical cancer screening and human papillomavirus testing experience in self-sampled Nigerian women.

Background: Cervical cancer is a disease of major public health significance which can be prevented by adequate screening. Objective: This study assessed the level of cervical cancer knowledge, attitude to screening and human papillomavirus testing experience in women who self-sampled for cervical cancer screening. Methods: A descriptive cross-sectional study involving 790 women that had human papilloma virus (HPV) testing at the gynae-oncology unit of the Lagos State University Teaching Hospital. Participants were assessed of their cervical cancer screening knowledge, attitude and HPV testing experience. High risk HPV (hr-HPV) nucleic acid testing was funded by the Clinton Health Access Initiative. Results: Majority (76.71%) of the respondents exhibited a high level of knowledge of cervical cancer, its causes, risk factors and prevention; and a positive experience with HPV self-sampling reported in 98.1%. hr-HPV positive rate was 13.4%. The most common reason (43%) for not having a cervical screening done was lack of a doctor's request. The most commonly known method of cervical screening by the respondents was Pap Smear test (55.31%). Conclusion: There is need for more education to improve the level of awareness and uptake of hr-HPV testing for cervical cancer in Lagos. Health care providers are not offering cervical cancer screening enough and this needs to be explored more in future studies.
