Objective: The aim of the study was to investigate the distribution and association between human papillomavirus (HPV) genotypes and integration as well as their correlation with cervical lesions.

Methods: Two hundred seven patients diagnosed with high-grade vaginal intraepithelial neoplasia (HG-VaIN) were recruited from the Women's Hospital School of Medicine Zhejiang University between 2015 and 2021 and assayed for HPV genotyping. HPV integration sequencing analysis was conducted using tissues from 53 patients with HG-VaIN and 4 patients with invasive vaginal carcinoma (IVC), along with paired cervical lesion specimens.

Results: A total of 207 patients with HG-VaIN were categorized as having cervical lesions unrelated to HG-VaIN (group A, 71 patients, 34.30%) or cervical lesion-related HG-VaIN (group B, 136 patients, 65.70%). With an average follow-up of 42.19 months, 12 of 153 patients progressed to IVC and were all from group B. HPV16 infection and the presence of cervical lesions were the 2 main factors associated with disease progression, with cervical lesion coexistence being an independent factor. Compared with group A (5/20, 25%), group B (17/33, 51.52%) showed a higher rate of HPV integration, as demonstrated using HPV integration sequencing analysis, with HPV16 being the most integrated genotype (72.73%). The integration analysis of 4 patients with IVC paired with cervical lesion specimens showed that 3 of the 4 pairs exhibited the same HPV infection and integration sites, indicating a high degree of homology in HPV integration between cervical lesions and HG-VaIN-induced IVC.

Conclusions: Patients with HG-VaIN associated with cervical lesions exhibited a higher risk of malignant transformation, necessitating more proactive treatment approaches.

Abstract: Untreated vulvar lichen sclerosus (VLS) can have a significant negative impact on quality of life, increase the risk of neoplastic transformation, and lead to irreversible architectural changes. Early and appropriate management using ultrapotent topical steroids is crucial to alleviate symptoms and prevent long-term complications. This study aimed to characterize clinical signs and architectural changes of 364 VLS patients at a tertiary center. The majority of the patients had sought care from ≥1 provider previously, were referred by a physician, had undergone prior vulvar biopsies, and had previously tried topical steroids. The authors observed predominantly mild clinical signs alongside more frequent severe architectural changes. These findings highlight the increased need for nuanced clinical evaluation, sufficient lifelong maintenance therapy to prevent architectural changes, and improved clinical scoring systems to differentiate between active VLS disease and residual damage.

Objective: The value of the transformation zone (TZ) is often overlooked in clinical settings. This study aims to assess TZ distribution, associated factors, and its impact on colposcopic diagnosis.

Methods: χ 2 tests were used to analyze demographics, clinical history, and tissue samples to examine the differences in TZ distribution. Factors affecting the TZ were explored using logistic regression, and diagnostic indicators were calculated.

Results: A total of 5,302 individual datasets were finally included. TZ1, TZ2, and TZ3 accounted for 31.6%, 38.5%, and 30.0%, respectively. Age is the most important factor that influences the location of the TZ. The proportion of TZ3 steadily increased with age, comprising over 55% in women over 50. The colposcopic diagnostic performance shows that high-grade squamous intraepithelial lesion or worse (HSIL+) sensitivity of TZ3 (58.1%, 95% confidence interval [CI] = 52.9-63.4) is significantly lower than that of TZ1 (69.8%, 95% CI = 65.5-74.1) and TZ2 (73.2%, 95% CI = 69.7-76.8). The HSIL+ specificity of TZ3 (96.3, 95% CI = 95.3-97.4) was higher than that of TZ1 (96.3, 95% CI = 95.2-97.3) and TZ2 (92.5, 95% CI = 91.1-93.9). The HSIL+ positive predictive value (81.3%, 95% CI = 76.4-86.2) and negative predictive value (89.3%, 95% CI = 87.6-90.9) for TZ3 are high, with no significant differences when compared with TZ1 and TZ2.

Conclusions: Age predominantly influences TZ location, with TZ3 being most frequently found in women over 50. While TZ3 poses a higher risk of missed diagnosis during colposcopy, it remains clinically valuable in identifying diseased and nondiseased status. Increasing colposcopists' awareness of TZ importance is needed in clinical practice.

Objectives: This article describe trends in the incidence and mortality of cervical (CC) and anal (AC) cancers by race and neighborhood socioeconomic status.

Methods: The Surveillance, Epidemiology, and End Results (SEER) database was used to construct a cohort of CC and AC cases from 2006 to 2018. Incidence rates and survival were calculated by race and neighborhood socioeconomic status (nSES). Annual percent change (APC) in incidence was calculated using linear regression, and 5-year overall survival (OS) by the Kaplan-Meier method.

Results: Of the cases, 33,487 CC and 16,018 AC cases were identified. Women of low nSES were nearly 4 times more likely to be diagnosed with cervical cancer than those of high nSES. Cervical cancer incidence declined marginally in all groups except for low nSES women who are White (APC 0.0). Women who are Black had lower 5-year OS than their nSES counterparts of other races (most notably for Black women of low nSES 53% vs White 63%). Similarly, the low nSES AC cohort contained nearly 3 times the number of diagnoses as the high nSES cohort. AC incidence increased most in women who are White (APC 1.8 and 2.2 for low and high nSES) and men who are Black and low nSES (APC 3.3). Five-year OS was lowest for men who are Asian American and Pacific Islander (40% and 50% for low and high nSES, respectively).

Conclusions: These data suggest a strong correlation between nSES, race, and their interaction on the incidence and survival trends of HPV-related disease and highlight inconsistent effects between cervical and anal cancers.

Objective: High-resolution anoscopy (HRA) with ablation of high-grade squamous intraepithelial lesions (HSIL) can prevent the development of anal cancer in people with HIV (PWH). The authors sought to characterize factors associated with successful HSIL resolution or local or metachronous recurrence.

Methods: The authors conducted a retrospective study of 62 PWH who underwent HRAs from December 1, 2017, to July 1, 2022. Participants were ≥30 years old with ≥2 HRAs and ≥1 HSIL lesions. Poisson and logistic regressions were used to assess factors associated with HSIL resolution and local or metachronous recurrence of HSIL.

Results: Of 62 PWH, 85.5% had resolution of at least 1 HSIL. Undergoing ≥5 HRAs with thermoablation was associated with HSIL resolution (adjusted rate ratio [aRR] = 2.82) (confidence interval [CI] = 1.55-5.15), p < .001). Tobacco use was negatively associated with resolution (aRR = 0.62 (CI = 0.43-0.90), p = .01). Of this cohort, 58.1% had HSIL recurrence. Having more HRAs (adjusted odds ratio [aOR] = 2.77 (CI = 1.27-6.06), p = .01) and female sex (aOR = 9.66 (CI = 1.14-81.85), p = .04) were associated with recurrence. Non-White race was negatively associated with recurrence (aOR = 0.12 (CI = 0.02-0.68), p = .04). This study was primarily limited by its retrospective nature and small sample size.

Conclusion: This study supports the utility of HRA/ablation for HSIL treatment with >85% of participants experiencing resolution of at least 1 HSIL. The authors found that having more HRAs was associated with a higher likelihood of resolution. However, the high rate of recurrence and progression to HSIL highlights the need for continued surveillance after treatment.

Objective: The aim of the study is to validate the applicability and performance of the 2019 US risk-based guideline for Chinese women.

Materials and methods: The authors analyzed 10,055 cases with data on human papillomavirus testing, cytology, and pathologically confirmed diagnosis (analysis-set). According to the 2019 US risk-based guideline, the authors recorded the risk value and triage recommendations for each case. Then, they assessed the concordance of the guideline triage recommendations with pathology diagnosis for the relevant case from the real-world projects.

Results: Among the analysis-set, 9,495 cases with an estimated risk value were identified as analysis cohort while the remaining 560 cases were cataloged as "special cases." Among the analysis cohort, 960 and 526 cases were pathologically confirmed as cervical intraepithelial neoplasia (CIN) 2+ and CIN3+, respectively. The US risk-based guideline recommended colposcopy or more aggressive interventions (Colp+) for 86.8% (833/960) of the CIN2+ and 95.8% (504/526) of the CIN3+ cases, with 87.1% sensitivity and 82.5% specificity for CIN3+ cases (AUC = 0.926, p < .0001). The US risk-based recommended no-Colp for 98.0% (6,142/6,269) of the pathologically confirmed CIN1 or benign cases. In addition, 97.3% (545/560) of the "special cases" cases were recommended as Colp+.

Conclusions: The 2019 US risk-based guideline works well with satisfied clinical sensitivity for CIN2+ and CIN3+ and seems applicable for cervical cancer screening in China.

Objectives: It is common practice to advise people with vulvar lichen sclerosus to perform vulvar self-examination (VSE) to optimize topical therapy and detect changes that may represent active disease, scarring, and/or squamous cell carcinoma development. The aim of this study was to better understand people's willingness and potential barriers to performing VSE.

Materials and methods: A cross-sectional survey was undertaken of all patients with vulvar LS presenting to a tertiary referral vulvar dermatology clinic in Australia, from June 2022 to January 2023. Patients who did not speak and read English were excluded. Ethics approval was obtained.

Results: Seventy-eight (66%) of 118 eligible patients completed the survey. Fifty-three (68%) of patients had examined their vulva at least once. Forty-one (49%) had been recommended VSE by a medical practitioner. All those recommended VSE had performed VSE at least once. In contrast, only 10 (27%) of the 37 patients not recommended VSE by a health professional had ever performed VSE. Seventy-nine percent of all patients reported that they were very likely or likely to perform VSE if it was recommended.Patients with higher education level and tampon use were more likely to perform VSE. Self-reported back problems were associated with being less likely to perform VSE.

Conclusions: More widespread VSE may result in earlier detection of the complications of vulvar lichen sclerosus. Most women would perform VSE if recommended by a health care provider; however, currently only half are receiving this advice. Further research should be performed to determine whether VSE affects clinical outcomes.

Objectives: The purpose of this study is to evaluate the content, delivery, and quality of medical information for vulvar lichen sclerosus on the social media platform TikTok.

Materials and methods: This is a descriptive, cross-sectional study. Using the third-party data scraping tool Apify, TikTok videos tagged with #lichensclerosus or "lichen sclerosus" were identified and sorted by view count. A sample of 100 videos was reviewed by 2 independent reviewers, excluding those not discussing lichen sclerosus. Videos were assessed using a coding document, the Patient Educational Materials Assessment Tool, and the DISCERN instrument. Interrater reliability was measured, and statistical analyses included Fleiss' kappa, intraclass correlation coefficient, t tests, and Wilcoxon rank sum test with Holm-Bonferroni correction.

Results: Content creators included patients (46%), health care professionals (30%), and others. Topics focused on clinical disease (52%) and treatment (48%). Evidence-based medicine was discussed in 71.7% of treatment-related videos, while 51.7% included nonevidence-based approaches, with a neutral or positive sentiment. Videos discussing topical steroids often had negative sentiments. Quality assessment revealed 61% of videos were understandable, 27% actionable, and 46% contained misinformation. Videos by health care professionals had less misinformation and higher quality scores compared to patient-generated content. Commercially biased videos were more understandable but contained more misinformation.

Conclusions: TikTok serves as a significant platform for sharing information on lichen sclerosus, but nearly half of the content contains misinformation. Health care professionals need to engage in social media to provide accurate information and counteract misinformation. Enhanced collaboration with patient advocates and careful resource sharing can improve the quality and reliability of medical information available online.

Objectives: Contributors to disparities and worse cervical cancer outcomes include limited education and loss to follow-up after an abnormal Pap smear. Effective interventions are necessary to engage diverse populations. The authors piloted an intervention to assess acceptability, knowledge uptake, and follow-up.

Materials and methods: This prospective pilot study recruited patients scheduled for colposcopy visits at a government-insured clinic and faculty clinics within an academic medical center to use the Patient Activated Learning System (PALS). The PALS intervention included 5 short educational videos about human papillomavirus and colposcopy. Participants completed a baseline knowledge questionnaire, viewed PALS videos followed by post-intervention knowledge and acceptability surveys. Perceptions of PALS, anxiety, and impact on follow-up were evaluated.

Results: Of 63 (70%) participants completing the intervention, 24 (38%) were from the government-insured clinic and 39 (62%) from faculty clinics. Median age was 36 (range 30-48), 38 (63%) were racial and ethnic minorities, and 21 (33%) were non-Hispanic White. The intervention improved knowledge scores for the entire cohort (60%-75%, p < .01), even when stratified by race/ethnicity ( p < .01 for all), income ( p < .01), education ( p < .01), practice ( p < .01), and insurance type ( p < .001). Participants found PALS convenient to use (4.6/5), enjoyable (4.2/5), and acceptable (4.6/5); 75% said the videos alleviated colposcopy-related anxiety, and 84% indicated PALS made them more likely to follow up. The guideline concordant follow-up rate among study completers was 73%.

Conclusion: In this pilot study, PALS was effective and acceptable among a diverse cohort. These free, widely viewed videos can successfully engage diverse populations to improve colposcopy knowledge and follow-up.

Objectives: Genital lichen sclerosus (LS) is a chronic mucocutaneous disorder causing considerable discomfort. Despite this, comprehensive comparison of LS impacts on quality of life (QoL), particularly on men's health or relative to other dermatological conditions like pemphigus, are sparse. This research aims to discern the effects of LS on sexual functionality and overall QoL, benchmarking against pemphigus patients and healthy controls. The study's intent is to broaden the understanding of sexual dysfunction, satisfaction, and psychological distress attributable to LS.

Materials and methods: From March 2021 to September 2023, this observational multicenter study at the affiliated university hospitals involved 176 individuals, 120 females and 56 males, with LS, pemphigus, or as controls. Questionnaires employed were the Female Sexual Function Index or the International Index of Erectile Function depending upon subject's gender, the General Health Questionnaire-12, the Clinical Lichen Sclerosus Score, and Pemphigus Disease Area Index. Differences in QoL were analyzed using either the Fisher exact test or the Mann-Whitney U test, and the correlation between Clinical Lichen Sclerosus Score sexual QoL using Spearman's coefficient.

Results: LS patients faced more sexual health challenges than pemphigus patients and healthy people. Women with LS had difficulties with lubrication and pain, men had less satisfaction during intercourse, and all had increased psychological distress, although less than those with pemphigus. A strong link between LS severity and worse sexual QoL, especially for women, was identified.

Conclusions: LS significantly affects sexual function and psychological well-being, both for men and women, reaffirming the need for comprehensive management.
