Culturally Competent Education and Human Papillomavirus Self-Sampling Achieves Healthy People 2030 Cervical Screening Target Among Low-Income Non-Hispanic Black and Hispanic Women.

PURPOSE: Disparities in cervical cancer screening, incidence, and mortality exist in the United States. Cervical cancer incidence and mortality rates in Texas are 20% and 32% higher, respectively, than national averages. Within Texas, these rates are significantly higher among non-Hispanic (NH) Black and Hispanic women. Cervical cancer screening uptake is lower among NH Black and Hispanic women (72.9% and 75.9%, respectively) compared with White women (85.5%) in Texas. METHODS: During March-August 2023, we conducted a pilot study that offered culturally competent education and human papillomavirus (HPV) self-sampling kits to women in two public housing projects in Houston, TX, that have predominantly NH Black or Hispanic residents. Among those eligible for cervical cancer screening, 35% (n = 24) of the NH Black and 34% (n = 16) of the Hispanic women were found to be underscreened per the US Preventive Services Task Force Guideline. We recruited 40 (24 NH Black and 16 Hispanic) eligible women for our study. The study was approved by the MD Anderson institutional review board and registered with ClinicalTrials.gov (NCT04614155-March 11, 2020). RESULTS: Seventy-five percent of the NH Black and 87% of the Hispanic participants completed the HPV self-sampling procedures per protocol. Samples of 17% NH Black and 12% Hispanic participants showed a performance error. Overall, cervical cancer screening uptake improved from 65% to 91% among NH Black and from 66% to 96% among Hispanic participants. CONCLUSION: Culturally competent education and HPV self-sampling resulted in remarkable improvement in cervical cancer screening uptake among underscreened NH Black and Hispanic women residents of Houston public housing projects. Implementing this strategy could significantly reduce cervical cancer incidence and mortality among similar populations in the United States and globally.

Retrospective analysis of negative cytology results correlated with a positive high-risk in the human papillomavirus result and subsequent results of patients over a period of three years.

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

Prevalence and incidence of anal high-grade squamous intraepithelial lesions in a cohort of cisgender men and transgender women who have sex with men diagnosed and treated during acute HIV acquisition in Bangkok, Thailand.

INTRODUCTION: Men who have sex with men (MSM), especially those living with HIV, are at an increased risk of anal cancer. The prevalence and incidence of its precursor, anal high-grade squamous intraepithelial lesions (HSILs), among MSM who started antiretroviral therapy during acute HIV acquisition are yet to be explored. METHODS: Participants in an acute HIV acquisition cohort in Bangkok, Thailand, who agreed to take part in this study, were enrolled. All participants were diagnosed and started antiretroviral therapy during acute HIV acquisition. Human papillomavirus (HPV) genotyping and high-resolution anoscopy, followed by anal biopsy as indicated, were done at baseline and 6-monthly visits. RESULTS: A total of 89 MSM and four transgender women were included in the analyses. Median age at enrolment was 26 years. Baseline prevalence of histologic anal HSIL was 11.8%. With a total of 147.0 person-years of follow-up, the incidence of initial histologic anal HSIL was 19.7 per 100 person-years. Factors associated with incident anal HSIL were anal HPV 16 (adjusted hazards ratio [aHR] 4.33, 95% CI 1.03-18.18), anal HPV 18/45 (aHR 6.82, 95% CI 1.57-29.51), other anal high-risk HPV (aHR 4.23, 95% CI 1.27-14.14), syphilis infection (aHR 4.67, 95% CI 1.10-19.90) and CD4 count <350 cells/mm3 (aHR 3.09, 95% CI 1.28-7.48). CONCLUSIONS: With antiretroviral therapy initiation during acute HIV acquisition, we found the prevalence of anal HSIL among cisgender men and transgender women who have sex with men to be similar to those without HIV. Subsequent anal HSIL incidence, although lower than that of those with chronic HIV acquisition, was still higher than that of those without HIV. Screening for and management of anal HSIL should be a crucial part of long-term HIV care for all MSM.

HPV genotyping in clinical samples using long-read single-molecule real-time sequencing.

Human papillomavirus (HPV) genotyping is widely used, particularly in combination with high-risk (HR) HPV tests for cervical cancer screening. We developed a genotyping method using sequences of approximately 800 bp in the E6/E7 region obtained by PacBio single molecule real-time sequencing (SMRT) and evaluated its performance against MY09-11 L1 sequencing and after the APTIMA HPV genotyping assay. The levels of concordance of PacBio E6/E7 SMRT sequencing with MY09-11 L1 sequencing and APTIMA HPV genotyping were 100% and 90.8%, respectively. The sensitivity of PacBio E6/EA7 SMRT was slightly greater than that of L1 sequencing and, as expected, lower than that of HR-HPV tests. In the context of cervical cancer screening, PacBio E6/E7 SMRT is then best used after a positive HPV test. PacBio E6/E7 SMRT genotyping is an attractive alternative for HR and LR-HPV genotyping of clinical samples. PacBio SMRT sequencing provides unbiased genotyping and can detect multiple HPV infections and haplotypes within a genotype.

High-Risk Human Papilloma Virus Genotype Distribution and Correlation with Cervical Cytomorphological Data in Turkish and Immigrant Women in Mersin Province.

Human papilloma virus (HPV) is the most common sexually transmitted viral agent in the world and the most common cause of cervical cancer. HPV prevalence and genotype distribution vary by region and demographic data. In a province in the south of Turkey that constantly receives immigration, we aimed to determine the prevalence of high-risk HPV (HR-HPV) genotypes, evaluate the compatibility between cervical Pap smear cytology results patients and HR-HPVs, and make an up-to-date contribution to the elucidation of epidemiological data. In this single-centre study, a total of 12,641 women aged 18 and over were evaluated retrospectively from January 2019 to July 2022. HPV detection and genotyping were analysed by the PCR method. Bethesda scoring was used for Pap smear cytological evaluation. The overall prevalence of HR-HPV was 12.6% (12.7% in Turkish women, 11.2% in foreign women). Among the typed HPVs that were detected, HPV-16 (31%) was found first, followed by HPV-18 (8%). The prevalence of HR-HPV was higher in women with abnormal cytology (977/1762, 55.4%) than in women with normal cytology (620/10879, 5.7%) (p<0.001). Turkey doesn't yet have a national HPV immunisation program. We think that determining the specific regional frequency of other HR-HPVs separately will be useful in the follow-up of the natural course of the type-specific infection and in vaccine studies in the future.

Exploring the Concordance Between High-Risk Human Papillomavirus Infections in Cervical and Oral Sites Among Females: A Cross-Sectional Study in Punjab, Pakistan.

PURPOSE: Human papillomavirus (HPV) is widely recognized as a key contributing factor in cervical and oropharyngeal cancers. However, there has been limited research on the prevalence of concurrent HPV infections in various anatomic regions. This study aimed to investigate the prevalence and specific types of high-risk HPV (HR-HPV) infections in the cervical and oral regions of females in Punjab, Pakistan. METHODS: We conducted a cross-sectional study involving women seeking care for general gynecologic issues at the gynecologic Outpatient Department of Lady Wallington Hospital in Lahore. After interviews and clinical examinations, we collected whole-saliva samples and high vaginal swabs from each participant. HR-HPV detection and genotyping were performed using real-time polymerase chain reaction at both the anatomic sites. RESULTS: In this study, 170 females, averaging 35.36 ± 8.305 years, participated. HR-HPV infection was more prevalent in the cervix (83/170 [48.8%]) than in the oral cavity (19/170 [11.2%]). Concordant HPV infections occurred in 10/170 participants (5.9%). HPV 16 was the most common genotype in cervical and oral locations, at rates of 21.8% and 5.3%, respectively, among concordant HR-HPV types. Socioeconomic status (P = .013), age at first sexual intercourse (P = .015), and history of oral sex (P = .01) were significantly associated with concurrent HR-HPV infection in both regions. CONCLUSION: This study suggests that HR-HPV cervical infections may increase the risk of oral transmission, especially during orogenital sexual practices. Thus, it is important to recognize that HPV infections may be linked in both areas. We emphasize the importance of comprehensive cervical and oral examinations and HPV vaccination in young women irrespective of their sexual practices.

Acceptability of self-collected vaginal samples for human papillomavirus testing for primary cervical cancer screening: comparison of face-to-face and online recruitment modes.

BACKGROUND: This study aimed to assess the acceptability and attitudes of women towards human papillomavirus (HPV) self-sampling and compare the effectiveness of two delivery modes utilising face-to-face and online website for cervical cancer screening in Hong Kong. METHODS: Women aged 30-65 years were invited to participate by distributing the study information pamphlets at the specialist clinics of a regional acute hospital. Those who were interested in participating were given the option to join directly face-to-face or through an online website. All participants provided informed consent and received self-sampling kits and acceptability questionnaires either immediately (face-to-face) or through the post after registering at the website (online). All participants were requested to collect their own vaginal samples using a swab which was then brushed on a DNA sample storage card and returned to the hospital either in person or by post. The self-collected samples were tested for high-risk HPV using the Sentis™ HPV assay, a validated isothermal nucleic acid amplification real-time fluorescent detection assay. The primary outcome was the uptake rate of HPV self-sampling. RESULTS: Of the 1998 women recruited (1200 face-to-face, 798 online), 1377 returned their samples, giving an overall uptake rate of 68.9%. The uptake rate was significantly greater in the face-to-face mode than in the online mode (74.6% vs. 60.4%, p < 0.001). The median age of the participants was 49 years, 43.7% were never or under-screened, and 7.1% had high-risk HPV detected. Overall, 82.1% of the participants reported self-sampling convenient, and 79.3% were not embarrassed when collecting self-samples. However, only 49.8% were confident that they had collected the self-samples correctly. Most (91.1%) of the participants expressed willingness to perform self-sampling again, mostly because it was simple (79.2%) and quick (56.3%). CONCLUSIONS: HPV self-sampling can serve as an alternative primary screening method for cervical cancer in Hong Kong, especially for individuals who have not been adequately screened in the past. Both face-to-face and online website recruitment were associated with high acceptability, emphasising the potential benefits of utilising different platforms and strategies for reaching diverse populations.

Prevalence of High-Risk HPV Detection and HPV Vaccination in Cervical Cancer Screening During the HPV Vaccination Era at Siriraj Hospital - Thailand's Largest National Tertiary Referral Center.

OBJECTIVE: To investigate the prevalence of high-risk (HR) human papillomavirus (HPV) detection and HPV vaccination among women undergoing cervical cancer screening during the HPV vaccination era at Siriraj Hospital - Thailand's largest national tertiary referral center. METHODS: This prospective cross-sectional study was conducted at our center's outpatient gynecology clinic during September-December 2021. Women aged ≥18 years with no previous hysterectomy, no history of preinvasive or invasive cervical cancer, and no current pregnancy who visited for cervical cancer screening were eligible for enrollment. Women with abnormal vaginal discharge/bleeding, and specimens with inadequate cellularity were excluded. We collected sociodemographic data, history of HPV vaccination, cervical cytology results, and high-risk HPV testing results. Reverse transcription polymerase chain reaction was used to determine HPV genotype. RESULTS: A total of 216 women (mean age: 41.7 years (range: 25-65), 75.9% premenopausal) were enrolled. Twenty of 216 (9.3%) women tested positive for HR-HPV, and 15 of 216 (6.9%) women had been previously vaccinated for HPV. The most common HPV genotypes detected were Group B infection (HPV 35/39/51/56/59/66/68) (38.9%), followed by HPV16 (27.78%), Group A infection (HPV 31/33/52/58) (27.8%), and HPV18 (5.56%). No HPV45 infection was detected. The detection rate of cytologic abnormalities was 4.16%. Three-quarters (77.8%) of patients with cytologic abnormalities were HR-HPV positive. CONCLUSION: Among the 216 women who underwent cervical cancer screening in this study, there was a 9.3% prevalence of HR-HPV infection, and a 6.9% prevalence of HPV vaccination. Among the 15 vaccinated women, 2 tested positive for HPV16 (1 normal cytology, 1 abnormal cytology).

Seegene Anyplex II assays detect HPV consistently using DNA extracts from different extraction methods.

The efficiency of PCR-based diagnostic assays can be impacted by the quality of DNA template, and anal samples can be particularly problematic due to the presence of faecal contaminants. Here, we compared the Quick-DNA Viral Kit (Zymo, Zymo Research, CA) and MagNA Pure 96 DNA and Viral NA Small Volume Kit (MP96, Roche) for use of the Seegene Anyplex II HPV28 assay (Anyplex28, Seegene) with anal samples. A total of 94 anal samples extracted using the MP96 and Zymo kits were tested via the Anyplex28, which detects high-risk human papillomavirus (HR-HPV, Panel A) and low-risk (LR-HPV, Panel B) HPV types. Testing the HR-HPV types (Panel A), 86 (91.5%) MP96 and 84 (89.4%) Zymo samples were deemed assessable. Overall agreement between the two methods was 87/94 (92.6%, 95% CI: 85.3-97.0) with the Kappa value of 0.678 (0.5-0.9). Of the 87 assessable samples, 50 (57.5%) were concordant, 34 (39.1%) partially concordant, and 10 (11.5%)discordant. In conclusion, the Anyplex28 produces comparable HPV genotyping results when using DNA extracts from either of these two methods.

Human papillomavirus and Epstein-Barr virus infection in benign thyroid lesions.

INTRODUCTION: The objective was to investigate the correlation between Epstein-Barr virus (EBV) and human papillomavirus (HPV) infection in the development of benign thyroid lesions. MATERIAL AND METHODS: 29 cases of Hashimoto's thyroiditis (HT), 133 cases of thyroid adenoma, and 34 cases of HT with thyroid adenoma paraffin embedded tissue samples were used for EBV and HPV quantitative detection. RESULTS: None of the tissue samples carried HPV DNA. In HT tissue samples, the positive rate of EBV was 55.2% (16/29). In thyroid adenoma tissue samples, the positive rate was 37.6% (50/133). In HT combined with thyroid adenoma tissue samples, the positive rate of EBV was 67.6% (23/34). There was no correlation between EBV infection and clinical features such as age and gender. CONCLUSION: The occurrence and development of benign thyroid lesions are closely related to EBV infection. HT combined with thyroid adenoma may be more susceptible to EBV infection than simple HT and thyroid adenoma, which provides a new idea for the diagnosis and treatment of benign thyroid lesions.

Relationship between vaginal and oral microbiome in patients of human papillomavirus (HPV) infection and cervical cancer.

BACKGROUND: The aim of this study was to assess the microbial variations and biomarkers in the vaginal and oral environments of patients with human papillomavirus (HPV) and cervical cancer (CC) and to develop novel prediction models. MATERIALS AND METHODS: This study included 164 samples collected from both the vaginal tract and oral subgingival plaque of 82 women. The participants were divided into four distinct groups based on their vaginal and oral samples: the control group (Z/KZ, n = 22), abortion group (AB/KAB, n = 17), HPV-infected group (HP/KHP, n = 21), and cervical cancer group (CC/KCC, n = 22). Microbiota analysis was conducted using full-length 16S rDNA gene sequencing with the PacBio platform. RESULTS: The vaginal bacterial community in the Z and AB groups exhibited a relatively simple structure predominantly dominated by Lactobacillus. However, CC group shows high abundances of anaerobic bacteria and alpha diversity. Biomarkers such as Bacteroides, Mycoplasma, Bacillus, Dialister, Porphyromonas, Anaerococcus, and Prevotella were identified as indicators of CC. Correlations were established between elevated blood C-reactive protein (CRP) levels and local/systemic inflammation, pregnancy, childbirth, and abortion, which contribute to unevenness in the vaginal microenvironment. The altered microbial diversity in the CC group was confirmed by amino acid metabolism. Oral microbial diversity exhibited an inverse pattern to that of the vaginal microbiome, indicating a unique relationship. The microbial diversity of the KCC group was significantly lower than that of the KZ group, indicating a link between oral health and cancer development. Several microbes, including Fusobacterium, Campylobacter, Capnocytophaga, Veillonella, Streptococcus, Lachnoanaerobaculum, Propionibacterium, Prevotella, Lactobacillus, and Neisseria, were identified as CC biomarkers. Moreover, periodontal pathogens were associated with blood CRP levels and oral hygiene conditions. Elevated oral microbial amino acid metabolism in the CC group was closely linked to the presence of pathogens. Positive correlations indicated a synergistic relationship between vaginal and oral bacteria. CONCLUSION: HPV infection and CC impact both the vaginal and oral microenvironments, affecting systemic metabolism and the synergy between bacteria. This suggests that the use of oral flora markers is a potential screening tool for the diagnosis of CC.

Assessing the performance and utility of targeted next-generation sequencing for screening and genotyping of human papillomaviruses.

A next-generation sequencing (NGS)-based Ezplex HPV NGS kit (SML Genetree, Seoul, Korea) was used for human papillomavirus (HPV) screening. Of 885 cervical swab samples, HPV was detected in 162 samples. High-risk HPVs were detected in 82 samples, and other types of HPV were detected in 13 samples (HPV86, 71, 102, 91, and 114). At the read depth ≥ 500, NGS results exhibited 100 % agreement among repeated tests. HPV NGS results were compared with those of real-time PCR assays, Anyplex HPV28 (Seegene, Seoul, Korea) (n = 383) and Cobas HPV (Roche, Mannheim, Germany) (n = 64); concordances were 92.4 % and 95.0 %, respectively. Sanger sequencing of discordant results (n = 13) produced compatible results with those of HPV NGS. Pap smear abnormalities were detected in 31 patients (3.5 %), and 19 patients had high-risk HPV. Using HPV NGS for screening, rare HPV subtypes were detected, and quantitative values were obtained as read depth.

Evaluating human papillomavirus testing, prevalence, and association with prognosis in head and neck squamous cell carcinoma by subsite: A national cancer database study.

PURPOSE: To compare human papillomavirus (HPV) testing, prevalence, and association with prognosis between head and neck squamous cell carcinoma (HNSCC) subsites. MATERIALS AND METHODS: This study utilized the National Cancer Database (NCDB) to identify patients diagnosed with HNSCC between 2010 and 2017. Rates of HPV testing, HPV-positivity, and changes in these rates over time were measured by subsite. The impact of HPV-positivity on overall survival across six head and neck subsites was assessed using multivariable-adjusted Cox proportional hazards analysis. RESULTS: A total of 121,550 patients were included. Of this cohort, 87,575 (72.1%) were tested for HPV, with the oropharynx (55,049/64,158; 85.8%) displaying the highest rates of testing and the sinonasal tract (1519/2853; 53.2%) displaying the lowest testing rates. Of the 86,136 with a definitive result, 46,878 (54.4%) were HPV-positive, with the oropharynx (40,313/54,205; 74.4%) displaying the highest rates of HPV-positivity and the oral cavity (1818/11,505; 15.8%) displaying the lowest. HPV-positive malignancy was associated with significantly improved adjusted overall survival in the oropharynx (HR = 0.42 [95% CI: 0.43-0.47]), oral cavity (HR = 0.86 [95% CI: 0.79-0.95]), sinonasal tract (HR = 0.63 [95% CI: 0.48-0.83]), larynx (HR = 0.78 [95% CI: 0.71-0.87]), and hypopharynx (HR = 0.56 [95% CI: 0.48-0.66]), but not the nasopharynx (HR = 0.93 [95% CI: 0.77-1.14]). CONCLUSION: HPV testing rates were significantly lower in non-oropharyngeal subsites. This is relevant as HPV-associated disease displayed significantly improved overall survival in both the oropharynx and four of five non-oropharyngeal subsites. While validation with prospective studies is necessary, these findings may warrant HPV testing in all HNSCC subsites.

Evaluation of Pre-Analytical Variables for Human Papillomavirus Primary Screening from Self-Collected Vaginal Swabs.

Human papillomavirus (HPV) primary screening is an effective approach to assessing cervical cancer risk. Self-collected vaginal swabs can expand testing access, but the data defining analytical performance criteria necessary for adoption of self-collected specimens are limited, especially for those occurring outside the clinic, where the swab remains dry during transport. Here, we evaluated the performance of self-collected vaginal swabs for HPV detection using the Cobas 6800. There was insignificant variability between swabs self-collected by the same individual (n = 15 participants collecting 5 swabs per participant), measured by amplification of HPV and human ß-globin control DNA. Comparison of self-collected vaginal swab and provider-collected cervical samples (n = 144 pairs) proved highly concordant for HPV detection (total agreement = 90.3%; positive percentage agreement = 84.2%). There was no relationship between the number of dry storage days and amplification of HPV (n = 68; range, 4 to 41 days). Exposure of self-collected dry swabs to extreme summer and winter temperatures did not affect testing outcomes. A second internal control (RNase P) demonstrated that lack of amplification for ß-globin from self-collected specimens was consistent with poor, but not absent, cellularity. These data suggest that self-collected vaginal samples enable accurate clinical HPV testing, and that extended ambient dry storage or exposure to extreme temperatures does not influence HPV detection. Furthermore, lack of ß-globin amplification in HPV-negative samples accurately identified participants who required recollection.

2023 global inventory of commercial molecular tests for human papillomaviruses (HPV).

To suit the needs of the human papillomaviruses (HPV) community comprehensively, a range of commercial HPV tests with different performance characteristics are required. Four periodic inventories of commercial HPV molecular tests present in the global market were published previously in 2010, 2012, 2015 and 2020. For the fifth inventory, data were retrieved from internal files and a detailed search using the main bibliographic databases as well as general internet search without period or language restrictions was performed in December 2023. At least 264 distinct HPV tests (and 511 test variants) were available globally in December 2023. A small 2020-2023 net increase in total numbers was observed, but with a strong introduction/withdrawal dynamic: 86 new distinct HPV tests (and 141 variants) were introduced and 76 tests (and 55 variants) were withdrawn from the market in the last four years. Although quality improvement of some tests was recorded, half of all HPV tests are still without a single peer-reviewed publication, and 79 % of tests are without published evidence that demonstrate performance characteristics are in line with requirements agreed in the HPV community. Only a relatively small pool of tests fulfill the operational/performance characteristics required to meet the global cervical cancer screening challenge. Although clinical and analytical performance characteristics of many commercial HPV tests are largely unknown, such tests are used worldwide in daily clinical practice and research, with potentially deleterious consequences. Due to this long-lasting unfavorable situation, significant scope for improvement persists for both manufacturers of HPV tests and the HPV community.

Testagem Molecular para Detecção de HPV e rastreamento do câncer do colo do útero / Molecular Testing for HPV Detection and Uterus Colon Cancer Tracking

INTRODUÇÃO: Evidências científicas robustas indicam que o rastreamento com testes moleculares para detecção de HPV oncogênico é mais sensível, eficaz/efetivo e eficiente, em termos do aumento de detecção de lesões precursoras e da redução da incidência e mortalidade por CCU, do que o rastreio com exame citopatológico. Outro aspecto fundamental é a maior detecção de casos de CCU em estágio inicial, precedendo em até 10 anos o diagnóstico pelo exame citopatológico. A detecção precoce leva a tratamentos menos mutilantes e onerosos, com excelente prognóstico e até com possibilidade de cura, impactando positivamente a custo-efetividade do rastreamento. Ademais, por apresentarem maior sensibilidade e valor preditivo negativo (VPN), quando comparados à citologia, os testes para detecção de HPV de alto risco permitem o aumento da idade de início do rastreio e do intervalo de testagem, melhorando a eficiência e otimizando o desempenho dos programas. PERGUNTA: "A testagem molecular para detecção de HPV

The risk of vaginal, vulvar and anal precancer and cancer according to high-risk HPV status in cervical cytology samples.

High-risk human papillomavirus (hrHPV) is the cause of virtually all cervical cancers, most vaginal and anal cancers, and some vulvar cancer cases. With HPV testing becoming the primary screening method for cervical cancer, understanding the link between cervical hrHPV infection and the risk of other anogenital cancers is crucial. We assessed the risk of vulvar, vaginal and anal cancer and precancer (VIN2+, VaIN2+ and AIN2+) in a prospective cohort study including 455,349 women who underwent cervical hrHPV testing in Denmark from 2005 to 2020. We employed Cox proportional hazard models, adjusting for age, calendar year and HPV vaccination status, and estimated hazard ratios (HRs) and 95% confidence intervals (CI). We used the Aalen Johansen estimator to calculate the absolute risks of VIN2+, VaIN2+ and AIN2+. In total, 15% of the women were hrHPV positive at baseline. A positive cervical hrHPV test was associated with increased incidence of vulvar, vaginal and anal squamous cell carcinoma (SCC). Five-year risk estimates of VIN2+, VaIN2+ and AIN2+ among hrHPV-positive women (0.45%, 0.14% and 0.12%) were higher than among hrHPV-negative women (0.14%, 0.01% and 0.05%). Particularly high risk was observed among the hrHPV-positive women of the oldest age, with a history of anogenital precancer and those not HPV vaccinated. In conclusion, our study confirms the association between cervical hrHPV infection and non-cervical anogenital precancers and cancers. Currently, no established risk threshold or guidelines for follow-up. As HPV testing becomes the primary method for cervical cancer screening, future data will help define high-risk groups and acceptable risk thresholds.

Atypical glandular cells in Pap tests: cytology-histology correlation and risk assessment with human papillopmavirus (HPV) testing.

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.
