Abstract
INTRODUCTION We assessed the impact of a nationwide screening programme to reduce the risk of anal cancer in a large cohort of high-risk patients with HIV. METHODS From a large database from one referral centre, all high-risk patients with HIV (men who have sex with men, history of anal or genital warts, or previous cervix human papillomavirus-related lesions) who were eligible to enter the French anal cancer screening programme (2011-2020) were retrospectively included. Adherence to the screening programme was defined as no interval >18 months between two visits. Standardized management included perianal visualization and standard anoscopy with biopsies of macroscopic abnormalities. RESULTS Overall, 700 patients with HIV were included (median follow-up 8.4 years [interquartile range 4.3-9.2] and 1491.6 patient-years), and 336 had one or more proctology visit. A total of 13 patients were diagnosed with anal squamous cell carcinomas. The risk of anal cancer was higher with anal intra-epithelial neoplasia grade 3 (AIN3; hazard ratio [HR] 44.5 [95% confidence interval {CI} 11.2-176.6], p < 0.001), AIN2 (HR 11.9 [95% CI 2.1-66.9], p = 0.005), or high-grade dysplasia (HR 23.4 [95% CI 7.9-69.1], p < 0.001) than with low-grade dysplasia or no lesion. Among the patients who were strictly adherent to the screening programme (4.6% [32/700]), we did not report any AIN or anal cancer, but we also did not observe any significant reduction in the risk of anal cancer (p = 0.51), AIN3 (p = 0.28), high-grade dysplasia (p = 0.19), or any AIN lesions (p = 0.10) compared with non-adherent patients. In contrast, screened patients were more likely to be diagnosed with anal warts (HR 3.71 [95% CI 2.14-6.42], p < 0.001). CONCLUSION Macroscopic high-grade dysplasia lesions are associated with a higher risk of developing anal cancer. Despite finding no cases of cancer during the screening programme, we also did not demonstrate a clear benefit from our screening programme for the prevention of anal cancer in high-risk patients with HIV.

Abstract
PURPOSE This study aimed to compare trichloroacetic acid (TCA) versus electrocautery (ECA) for the treatment of anal high-grade squamous intraepithelial lesions (HSIL). METHODS This is an observational, single-center study. All subjects with HIV who had anal HSIL treated with TCA or ECA from 2010 to 2022 were included. Effectiveness was evaluated by on-treatment analysis, defining response as the resolution of HSIL and recurrence as a new diagnosis of HSILs during follow-up. A propensity score analysis was used to adjust for confounding factors. RESULTS In total, 227 and 260 HSIL episodes were treated with ECA and TCA, respectively. Response was observed in 61.7% (95% CI: 55.3-68) of cases treated with ECA and in 73.1% (95% CI: 67.8-78.5) with TCA (p = .004). The effectiveness of TCA was higher in large and multifocal HSILs. Side effects were common with both treatments, but no serious events were described. Tolerability was good in 77.1% and 80.7% of patients treated with ECA and TCA, respectively. At 24 months, recurrent HSIL were observed in 36.3% (95% CI: 27.3-45) and 28% (95% CI: 20.2-35.8) in the ECA and TCA groups (p = .049). A nadir CD4 cell count ≤200 cells/µl was found to be a risk factor for recurrence (OR: 1.77; 95% CI: 1.12-2.78). CONCLUSIONS In this study, treatment with TCA showed high effectiveness, low recurrence and good tolerability. Considering the benefits of TCA, it could be considered one of the first-line treatments for anal HSIL.

Abstract
Anal squamous cell carcinoma (SCC) is not a common disease in the general population, although its incidence is higher in people living with human immunodeficiency virus (PLWH). Anal SCC is caused by human papillomavirus (HPV) infection and arises from premalignant lesions termed squamous intraepithelial lesions (SILs). SIL surveillance programs are based on the early detection and treatment of SILs, especially those with a higher risk of transforming into cancer. An anal surveillance program has been under development in our institution since 2011. In this context, we performed a retrospective cohort study at the anal dysplasia unit of Álvaro-Cunqueiro Hospital (Spain). Epidemiological and clinical data were gathered from our Infectious Diseases Sample Collection (an open sample cohort including PLWH) from January 2011 to January 2022. A total of 493 PLWH were considered, 122 (24.7%) of whom were diagnosed with anal dysplasia at baseline, including 2 cases of anal SCC. Briefly, most of individuals were young men (median age, 38 years old) born in Spain (76%), whose vaccination rate before their inclusion in the program was scarce (<3%). Throughout the study period, 81 (16.4%) cases were diagnosed with high-grade squamous-intraepithelial lesions (HSILs) and 3 with anal SCC. At the baseline, severe immunosuppression (i.e., nadir CD4+ lymphocyte count below 200 cell/μL), and prior diagnosis of condyloma acuminata were more frequent within the group with SILs. Conversely, the baseline CD4+ lymphocyte count was similar among both groups. HPV-16 was related to a higher risk of HSILs (odds ratio: 2.76). At the end of the follow-up, 385 PLWH had been retained in care; one patient had died of anal cancer. Anal dysplasia was common (25% of cases), especially among patients infected by HPV-16, diagnosed with condyloma acuminata, and who were severely immunosuppressed. HPV-16 was the main risk factor for the presentation of HSILs.

Abstract
BACKGROUND The rate of anal squamous cell cancer (aSCC) is increasing among women living with HIV. Treatment of precursor high grade squamous intraepithelial lesions (HSIL) may reduce the risk of progression to aSCC. The objective of this study was to examine effects of a dedicated high-resolution anoscopy (HRA) clinic on management of HSIL in women with HIV. METHODS Women living with HIV who underwent anal dysplasia screening at a single institution between 2006 and 2020 were reviewed. Those who underwent screening before (Group A) and after (Group B) the implementation of an HRA program in 2017 were compared. The primary outcome of interest was the successful detection and treatment of HSIL. RESULTS A total of 201 women living with HIV underwent anal dysplasia screening between 2006 and 2020. Seventy-seven patients were found to have abnormal anal cytology requiring further treatment: 43 (55.8%) in Group A and 34 (44.2%) patients in Group B. Of the patients with abnormal anal cytology, 76.7% of patients in Group A received further biopsy and treatment, whereas 79.4% of Group B patients underwent subsequent biopsy and treatment. In propensity score weighting logistic regression analysis, the Group B was 4.6 times as likely to diagnosis HSIL on biopsy compared to Group A (OR = 4.60, 95% CI: 1.15 to 18.38, P = .03). CONCLUSIONS Anal dysplasia is common among women living with HIV. The establishment of a HRA program was associated with increased identification and treatment of HSIL among women living with HIV, which may prevent the progression to aSCC.

Abstract
People living with human immunodeficiency virus (HIV) are at high risk for anal cancer. Anal cancer screenings are recommended annually for US veterans with HIV. Screenings can identify treatable precursor lesions and prevent cancer development. In a previous study, we found screening rate to be only 15%. Semistructured interviews were conducted with Veterans Affairs (VA) providers who treat veterans living with HIV. Participants described their experiences with anal cancer screenings. Researchers developed a codebook based on Theoretical Domains Framework (TDF) and coded data using thematic analysis to identify barriers to anal cancer screenings. Twenty-three interviews were conducted with VA providers representing 10 regions. Barriers identified corresponded with five targetable TDF domains: Knowledge, Skills, Environmental Context/Resources, Professional Roles/Identities, and Social Influence. Many providers lacked knowledge of screening protocols. Knowledgeable providers often lacked needed resources, including swabs, clinic space, reliable pathology, access to high-resolution anoscopy, or leadership support to implement a screening program. Providers mentioned competing priorities in the care of veterans with HIV infection and lack of skilled/trained personnel to perform the tests. It was often unclear which provider specialty should "own" screening responsibilities. Additional factors included patient discomfort with screening exams. Anal cancer screening protocols are recommended but not widely adopted in VA. There is a critical need to address barriers to anal cancer screenings in veterans. The TDF domains identified align with five intervention domains to target, including education, training, resource/environment, delineation of provider roles, and improved counseling efforts. Targeting these barriers may help improve the uptake of anal cancer screenings within VA.

Abstract
Anal cancer is a major health problem. This study seeks to determine if the topical protease inhibitor Saquinavir (SQV), is effective at the prevention of anal cancer in transgenic mice with established anal dysplasia. K14E6/E7 mice were entered into the study when the majority spontaneously developed high-grade anal dysplasia. To ensure carcinoma development, a subset of the mice was treated with a topical carcinogen: 7,12-Dimethylbenz[a]anthracene (DMBA). Treatment groups included: no treatment, DMBA only, and topical SQV with/without DMBA. After 20 weeks of treatment, anal tissue was harvested and evaluated histologically. SQV was quantified in the blood and anal tissue, and tissue samples underwent analysis for E6, E7, p53, and pRb. There was minimal systemic absorption of SQV in the sera despite high tissue concentrations. There were no differences in tumor-free survival between SQV-treated and respective control groups but there was a lower grade of histological disease in the mice treated with SQV compared to those untreated. Changes in E6 and E7 levels with SQV treatment suggest that SQV may function independently of E6 and E7. Topical SQV decreased histological disease progression in HPV transgenic mice with or without DMBA treatment without local side effects or significant systemic absorption.

Abstract
The artemisinin family of compounds is cytopathic in certain cancer cell lines that are positive for human papillomaviruses (HPV) and can potentially drive the regression of dysplastic lesions. We evaluated the efficacy of topical dihydroartemisinin (DHA) on cervical dysplasia and anal dysplasia in two papillomavirus mouse models: K14E6/E7 transgenic mice, which express HPV16 oncogenes; and immunodeficient NOD/SCID gamma (NSG) mice infected with Mus musculus papillomavirus (MmuPV1). Mice started treatment with DHA at 25 weeks of age (K14E6/E7) or 20 weeks post infection (MmuPV1-infected), when the majority of mice are known to have papillomavirus-induced low- to high-grade dysplasia. Mice were treated with or without topical DHA at the cervix or anus and with or without topical treatment with the chemical carcinogen 7,12 dimethylbenz(a)anthracene (DMBA) at the anus of in transgenic mice to induce neoplastic progression. Mice were monitored for overt tumor growth, and tissue was harvested after 20 weeks of treatment and scored for severity of histological disease. For MmuPV1-infected mice, anogenital lavages were taken to monitor for viral clearance. Tissues were also evaluated for viral gene expression at the RNA and/or protein levels. Treatment with topical DHA did not reduce dysplasia in the anogenital tract in either papillomavirus-induced mouse model and did not prevent progression to anal cancer in the DMBA-treated K14E6/E7 mice.

Abstract
BACKGROUND Care cascades can inform providers about differences in engagement and retention in care between patient populations thereby improving participation by targeting interventions more effectively. The objective of this study was to assess the uptake and retention of participants along the anal cancer screening algorithm within a single HIV clinic. METHODS Retrospective procedural and demographic data were collected within a Ryan White HIV/AIDS Program clinic from 18 December 2017 to 29 May 2021. A care cascade was constructed among eligible participants who engaged and were retained in the anal cancer screening algorithm. Engagement was defined as having at least one anal Pap smear. Retention was defined as having a follow-up anal Pap smear, and/or high resolution anoscopy, as indicated. Risk ratios (RR) were calculated to reveal factors associated with initiation and retention in screening. RESULTS Of 821 eligible participants, 312 (38%) engaged in screening and 205 (66%) were retained in care. Anoreceptive intercourse was positively associated with engagement (RR 2.81, 95% confidence interval [CI] 2.05-3.90, p<0.001), whereas male gender was negatively associated (RR 0.26, 95% CI 0.20-0.33, p<0.001). Abnormal cytology results on Pap smear were associated with retention (RR 1.39, 95% CI 1.03-1.86, p=0.03). CONCLUSIONS Overall engagement in anal cancer screening is low within our clinic, particularly among men, but retention in the screening program is notably better, especially among those with abnormal cytology. Target populations have been identified to increase awareness, and qualitative studies are underway to understand perceptions and barriers to engagement in anal cancer screening.

Abstract
In June 2019 the Centers for Disease Control and Prevention (CDC) convened an advisory group to assist in development of the 2021 CDC sexually transmitted infections (STI) guidelines. The advisory group on anal cancer screening and prevention met to formulate key questions in this field. The group examined published literature and abstracts to assess evidence and give recommendations for development of the CDC guidelines. This article summarizes key questions, evidence, recommendations, and areas for further research for the screening, diagnosis, and prevention of anal cancer.

Abstract
OBJECTIVE Our study aim was to validate the use of computer-aided narrative content analysis in the extraction of standard diagnostic categories using an archived cytology database that included individually overread reference classification. DESIGN A retrospective analysis of narrative anal cytology results collected on HIV-infected patients at the University of California, San Diego between January and December 2001. METHODS We used computer-assisted content analysis extraction methodology using Wordstat 8.0 (Provalis Research) that operated using a classification dictionary that we developed for the following diagnostic categories: NAMC, ASCUS, LSIL, HSIL. We compared its accuracy to a physician overread manually extracted method: that classified each report into the most severe diagnostic category referenced in the narrative report. Agreement between content analysis mapped diagnostic categories and the reference category was evaluated using kappa agreement. RESULTS During 2001, 901 patients underwent 997 anal cytological examinations as routine screening. By reference diagnostic category: 54 (5.4%) were unsatisfactory, 460 (46.1%) were NAMC, 291 (29.2%) were ASCUS, 131 (13.1%) were LSIL, and 61 (6.1%) were HSIL. Computer-aided content analysis extracted a single diagnosis from each report in 963 (96.2%) cases and two diagnoses in 38 (3.8%) cases. The Kappa agreement was 0.96 (0.019 s.e.). There were 29 cases classified ASCUS by reference category but LSIL by adjudicated content analysis. A focused review indicated that the over reader assigned reference category was in error. CONCLUSION Computer-aided narrative content analysis of anal cytology results yielded accurate and time-efficient classification into meaningful diagnostic categories that can be used to evaluate screening programs and modeling natural history.

Abstract
AIM Emerging evidence has suggested that metformin may be protective against the development of human-papillomavirus-related cancers. Anal intraepithelial neoplasia (AIN) is highly associated with human papillomavirus infection and a precancerous status of anal cancer. The aim of this study was to investigate the relationship between metformin usage and the development of AIN in a large national sample. METHODOLOGY The IBM MarketScan dataset was used to design a nested case-control study from 2010 to 2017. Patients aged 18-65 years with type 2 diabetes mellitus (DM) were evaluated, and cases of AIN were identified. Four controls were randomly selected in the risk set of each case by using incidence density sampling. The association between metformin usage and AIN was assessed using multivariate logistic regression modelling. RESULTS A total of 258 patients with type 2 DM were diagnosed with AIN during the study interval, and these were matched to 1032 control patients without a diagnosis of AIN. Patients who developed AIN had 38% lower odds of prior metformin use compared to those without a history of AIN (P < 0.01) and this finding remained robust after adjusting for age, sex, human immunodeficiency virus infection and DM complications (P = 0.02). Patients with AIN had 56% lower odds of long-term metformin use compared to control patients (P = 0.01). CONCLUSIONS An AIN diagnosis in patients with DM is associated with 56% lower likelihood of prior metformin use. This relationship suggests that metformin could potentially play a protective role against AIN. Prospective studies in non-diabetic patients are warranted to examine these findings further.

Abstract
Background. Anal HPV infection, anal dysplasia and, ultimately, anal cancer are particularly common in HIV-infected men who have sex with men. Treatment of anal dysplasia, aiming to prevent evolution to squamous cell carcinoma of the anus, is currently limited to direct ablation and/or application of topical therapy. The aim of the present study is to investigate the effect of oral bacteriotherapy (Vivomixx® in EU, Visbiome® in USA) on anal HPV infection and HPV-related dysplasia of the anal canal in HIV-infected men who have sex with men. Methods. In this randomized, placebo-controlled, quadruple-blinded trial (NCT04099433), HIV-positive men who have sex with men with anal HPV infection and HPV-related dysplasia were randomized to receive oral bacteriotherapy or placebo for 6 months. Anal HPV test, anal cytology and high resolution anoscopy with biopsies of anal lesions were performed at baseline and at the end of the study. Safety and tolerability of oral bacteriotherapy were also evaluated. Interim analysis results were presented. Results. 20 participants concluded the study procedures to date. No serious adverse events were reported. In respect to participants randomized to placebo, individuals in the experimental arm showed higher rate of anal dysplasia regression (p = 0.002), lower rate of onset of new anal dysplasia (p = 0.023) and lower rates of worsening of persistent lesions (p = 0.004). Clearance of anal HPV infection was more frequently observed in the bacteriotherapy group (p = 0.067). Conclusion. Being an interim analysis, we limit ourselves to report the preliminary results of the current study. We refer the conclusions relating to the possible effectiveness of the intervention to the analysis of the definitive data.

Abstract
BACKGROUND Renal transplant recipients (RTRs) have increased risk of human papillomavirus (HPV)-related cancers, including anal cancer. We investigated the prevalence of anal high-grade intraepithelial lesions (HSILs) in RTRs compared with immunocompetent controls and risk factors for anal HSIL in RTRs. METHODS We included 247 RTRs and 248 controls in this cross-sectional study. We obtained anal samples for HPV testing with INNO-LiPA and performed high-resolution anoscopy on all participants. The participants completed a questionnaire on lifestyle and sexual habits. We used logistic regression to estimate odds ratios (ORs) of histologically confirmed anal HSIL in RTRs vs controls and risk factors for anal HSIL in RTRs, stratified by sex and anal high-risk (hr) HPV status, adjusting for age, smoking, lifetime sexual partners, and receptive anal sex. RESULTS RTRs had higher anal HSIL prevalence than controls, both among men (6.5% vs 0.8%; adjusted OR [aOR], 11.21 [95% confidence interval {CI}, 1.46-291.17]) and women (15.4% vs 4.0%; aOR, 6.41 [95% CI, 2.14-24.10]). Among those with anal hrHPV, RTRs had higher anal HSIL prevalence than controls (33.8% vs 9.5%; aOR, 6.06 [95% CI, 2.16-20.27]). Having had receptive anal sex (aOR, 6.23 [95% CI, 2.23-19.08]) or genital warts (aOR, 4.21 [95% CI, 1.53-11.48]) were risk factors for anal HSIL in RTRs. All HSIL cases occurred in individuals with anal hrHPV. CONCLUSIONS RTRs had increased risk of anal HSIL compared with immunocompetent controls, with particularly high prevalence in female RTRs. Receptive anal sex, previous genital warts, and anal hrHPV infection were risk factors for anal HSIL in RTRs. Screening for anal HSIL in RTRs should be considered.

Abstract
BACKGROUND The Department of Veterans Affairs cares for the largest population of patients with HIV of any healthcare system in the United States. Screening for anal dysplasia/cancer is recommended for all veterans with HIV. Exams are invasive, burdensome, and resource intensive. We currently lack markers of disease to tailor screening. OBJECTIVE The purpose of this study was to establish the prevalence of advanced anal disease (high-grade dysplasia and anal cancer) and to determine whether CD4/CD8 ratio correlates with risk. DESIGN This was a retrospective regional cohort study of veterans with HIV. SETTINGS The study was conducted at eight medical centers between 2001 and 2019. PATIENTS Patients with advanced disease were compared with patients with nonadvanced anal pathology. MAIN OUTCOME MEASURES Logistic regression modeling was used to estimate adjusted odds of disease as a function of CD4/CD8. Lowest (nadir) CD4/CD8 and nearest CD4/CD8 ratio in each cohort were evaluated. RESULTS A total of 2267 veterans were included. Fifteen percent had anal pathology (112 with advanced disease (37 cancer and 75 high-grade), 222 with nonadvanced disease). Nadir and nearest ratio were lower in patients with advanced disease versus nonadvanced (0.24 vs 0.45 (p < 0.001) and 0.50 vs 0.88 (p < 0.001)). In adjusted models, a 1-unit increase in nadir or nearest ratio conferred decreased risk of advanced disease (OR = 0.19 (95% CI, 0.07-0.53); p < 0.001; OR = 0.22 (95% CI, 0.12-0.43); p < 0.001). Using a minimum sensitivity analysis, a cutoff nadir ratio of 0.42 or nearest ratio of 0.76 could be used to risk stratify. LIMITATIONS This was a retrospective analysis with a low screening rate. CONCLUSIONS In a regional cohort of veterans with HIV, 15% were formally assessed for anal dysplasia. Advanced anal disease was present in 33% of those screened, 5% of the HIV-positive population. A strong predictor of advanced disease in this cohort is the CD4/CD8 ratio, which is a promising marker to stratify screening practices. Risk stratification using CD4/CD8 has the potential to decrease burdensome invasive examinations for low-risk patients and to intensify examinations for those at high risk.

PREVALENCIA DE DISPLASIA ANAL DE ALTO GRADO Y CNCER ANAL EN VETERANOS QUE VIVEN CON EL VIH Y LA RELACIN CD / CD COMO MARCADOR DE MAYOR RIESGO UN ESTUDIO DE COHORTE REGIONAL RETROSPECTIVE ANTECEDENTES:El Departamento de Asuntos de Veteranos atiende a la población más grande de pacientes con el virus de inmunodeficiencia humana (VIH) de cualquier sistema de salud en los Estados Unidos. Se recomienda la detección de displasia / cáncer anal para todos los veteranos con VIH. Los exámenes son invasivos, onerosos y requieren muchos recursos. Actualmente carecemos de marcadores de enfermedad para adaptar la detección.OBJETIVO:Establecer la prevalencia de enfermedad anal avanzada (displasia de alto grado y cáncer anal) y determinar si la relación CD4 / CD8 se correlaciona con el riesgo.DISEÑO:Estudio de cohorte regional retrospectivo de veteranos con VIH.AJUSTE:Ocho centros médicos entre 2001-2019.PACIENTES:Se comparó a pacientes con enfermedad avanzada con pacientes con patología anal no avanzada.PRINCIPALES MEDIDAS DE RESULTADO:Se utilizó un modelo de regresión logística para estimar las probabilidades ajustadas de enfermedad en función de CD4 / CD8. Se evaluó la relación CD4 / CD8 más baja (nadir) y la relación CD4 / CD8 más cercana en cada cohorte.RESULTADOS:Se incluyeron un total de 2267 veteranos. El 15% tenía patología anal (112 enfermedad avanzada (37 cáncer, 75 de alto grado), 222 enfermedad no avanzada). El nadir y el cociente más cercano fueron menores en los pacientes con enfermedad avanzada frente a los no avanzados (0,24 frente a 0,45 (p <0,001) y 0,50 frente a 0,88 (p <0,001)), respectivamente. En modelos ajustados, el aumento de una unidad en el nadir o el cociente más cercano confirió una disminución del riesgo de enfermedad avanzada (OR 0,19 (IC del 95%: 0,07, 0,53, p <0,001)) y (OR 0,22 (IC del 95%: 0,12, 0,43, p <0,001))), respectivamente. Utilizando un análisis de sensibilidad mínima, se podría utilizar un cociente del nadir de corte de 0,42 o el cociente más cercano de 0,76 para estratificar el riesgo.LIMITACIONES:Análisis retrospectivo con una tasa de detección baja.CONCLUSIONES:En una cohorte regional de veteranos con VIH, el 15% fueron evaluados formalmente por displasia anal. La enfermedad anal avanzada estuvo presente en el 33% de los examinados, el 5% de la población VIH +. Un fuerte predictor de enfermedad avanzada en esta cohorte es la relación CD4 / CD8, que es un marcador prometedor para estratificar las prácticas de detección. La estratificación del riesgo usando CD4 / CD8 tiene el potencial de disminuir los exámenes invasivos onerosos para los pacientes de bajo riesgo e intensificar los exámenes para los de alto riesgo.

Abstract
This single-center, retrospective cohort study sought to estimate the cumulative incidence in HIV-1-infected patients of biopsy-proven high-grade anal intraepithelial neoplasia (HGAIN) recurrence after infrared coagulation (IRC) treatment. The study was based on data from a prospectively compiled database of 665 HIV-1-infected outpatients who attended a hospital Clinical Proctology/HIV Unit between January 2012 and December 2015. Patient records were checked to see which ones had received IRC treatment but later experienced a recurrence of HGAIN. Cytology samples were also checked for the presence of human papilloma virus (HPV). A total of 81 of the 665 patients (12%, 95%CI: 10–15%), of whom 65 were men and 16 women, were diagnosed with HGAIN and again treated with IRC. Of these 81, 20 (25%) experienced recurrent HGAIN, this incidence being true of both men (16/65, 95%CI: 19–57%) and women (4/16, 95%CI: 10–50%). The median time to recurrence was 6 (2–19) months overall, 6 (2–19) months in men, and 4 (2–6) months in women. HPV infection was detected in all patients except two, with HPV-16 being the most common genotype. This rate of incidence of recurrent HGAIN following IRC treatment is consistent with other reports and highlights the importance of continued post-treatment surveillance, particularly in the first year.

Abstract
AIM The incidence of anal squamous cell carcinoma (SCC) has increased dramatically in the USA. The squamous intraepithelial lesion has been identified as a precursor lesion to SCC, stratifying the abnormality into low grade or high grade. There have been studies on the prevalence of incidentally found SCC in haemorrhoidectomy specimens, but there are no studies to date on the incidence of dysplasia. The purpose of this study was to establish a baseline incidence of dysplasia that provides helpful information for future epidemiological studies. METHODS This is a retrospective review of patients who underwent haemorrhoidectomy from 2005 to 2019. Pathology regarding the type of dysplasia, medications, and diagnoses that may predispose to immunosuppression were collected. RESULTS In all, 810 patients with a mean age of 51.7 (range 20-91) years underwent haemorrhoidectomy. Eighteen (2.2%) of the patients had abnormal pathology (low-grade squamous intraepithelial lesion, 3; high-grade squamous intraepithelial lesion, 12; SCC, 2; adenocarcinoma, 1). Thirty-seven (4.5%) of the entire cohort had some risk factors for immunosuppression: chronic steroid use (nine), human immunodeficiency virus (HIV) (13), biologic medications (six), transplant recipients (two) and immunocompromising diseases (four). Only 4/18 patients had an immunosuppression risk in that all four of these patients were HIV-positive. Surveillance following excision was undertaken for an average of 6 (range 1-12) months, during which time four patients underwent a repeat biopsy. DISCUSSION Anal dysplasia found in an otherwise asymptomatic population has a prevalence of 2.2%. This finding supports the routine examination of benign anorectal specimens undergoing microscopic examination. Interestingly, the majority of the patients identified had no immunosuppressant risk factors.

Abstract
AIM As the understanding of anal dysplasia continues to develop, controversy remains regarding treatment of these lesions. The purpose of this study was to evaluate lesion type (flat vs exophytic) and the association between morphology and dysplasia. METHODS This was a single-centre retrospective analysis of a prospectively collected pathological database of patients > 17 years old who underwent operative excision/biopsies for presumed anal condyloma or dysplasia from 2009 to 2018. The analysis includes comparisons between patient factors, phenotype and grade of dysplasia. RESULTS Sixty-nine patients had 423 lesions. The mean age of the study population was 48.2 years. 62.3% were men and 46.4% of patients were black. 47.8% of patients were human immunodeficiency virus (HIV) positive and 39.1% were men who have sex with men (MSM). There were 176 (41.6%) flat lesions and 234 (55.3%) exophytic lesions. Exophytic lesions were 2.5-fold more likely to be associated with a higher grade of dysplasia than flat lesions (OR 2.63, 95% CI 1.09-6.32). Neither lesion type nor dysplasia severity was associated with human papillomavirus, lesion location or patient characteristics, including race, MSM or HIV status. DISCUSSION Exophytic lesions were more than twice as likely to have advanced dysplasia compared with flat lesions. A clearer understanding of the association between gross lesion appearance and dysplasia will allow more appropriate counselling of patients and the development of better screening and treatment guidelines for anal condylomata and dysplasia.

Abstract
INTRODUCTION Studies have shown that the PD-1/PD-L1 immunomodulatory pathway slows down anti-tumor immunity in a number of cancers. The description of the expression of these molecules has never been performed in anal low-grade/high grade squamous intra-epithelial lesions (LSIL/HSIL respectively). MATERIALS AND METHODS Patients followed in the AIN3 cohort were routinely sampled. For each selected sample, an immunohistochemical study was performed with anti-CD8, PD-1, PD-L1 antibodies. The presence and distribution of CD8+ lymphocytes, and the presence of PD-1+ lymphocytes and PD-L1+ epithelial cells were assessed. The comparison of these characteristics was performed between the HSIL and LSIL groups. RESULTS 33 patients were included and 78 samples selected (60 HSIL and 18 LSIL). CD8+ lymphocytes were observed more frequently in HSIL versus LSIL in the lamina propria or intra epithelial (respectively 90% vs. 60%, p = 0.01; and 62% vs. 33%, p = 0.04). PD-1+ lymphocytes were observed more frequently in HSIL versus LSIL (41% vs 11%, p = 0.03). There was no difference between HSIL and LSIL for PD-L1+ epithelial cells. CONCLUSIONS Anal dysplastic lesions are accompanied by an inflammatory lymphocytic infiltrate expressing CD8 and PD-1, more frequent in high-grade lesions. These results highlight the involvement of the PD-1/PD-L1 pathway in the natural history of anal dysplasia.

Abstract
AIM Human papillomavirus (HPV)-related anal squamous cell dysplasia has been well-reported in high-risk (HR) patients [human immunodeficiency virus (HIV)-positive, men having sex with men (MSM) or immune-suppressed transplant recipients]. However, data are extremely limited for all other patients. This study reports treatment outcomes for HPV-related dysplasia in a population of non-HR patients. METHOD A retrospective study was performed to review treatment efficacy in non-HR patients diagnosed with anal dysplasia or superficially invasive squamous cell carcinoma of the anus (SISCCA) with at least 12-months' follow-up; HR patients were excluded. Medical records were reviewed for demographics, pathology, cytopathology, treatment and recurrences. RESULTS Forty-one patients were identified (34 women). The median age at diagnosis was 58 years (range 26-85) and median follow-up was 26 months (range 12-51). At diagnosis, 36 patients had anal dysplasia and five patients had SISCCA. Treatment outcomes (resolved versus recurrent) differed between treatment modalities (P = 0.014). Topical and fulguration-only treatment modalities were superior to wide local excision (WLE) (P < 0.006 and P < 0.008, respectively). Fourteen (39%) patients had recurrent dysplasia at a median of 14 months (range 4-62); eight patients developed a second recurrence at a median of 14 months (range 11-26). No SISCCA patient had a recurrence, but two patients progressed to anal cancer after treatment. CONCLUSION The behaviour of anal dysplasia reported in this under-represented, small group of non-HR patients reveals that treatment for anal dysplasia is not necessarily a single event and nonexcisional treatments may be favourable to WLE. Though the true denominator of this population is unknown, treatment may not prevent the recurrence of dysplasia or progression to cancer, warranting close follow-up.

Abstract
People living with HIV are at high risk for anal cancer (AC); however, the impact of screening for and treatment of precancerous anal lesions on AC incidence remains uncertain. In 2013, we conducted a survey of HIV providers evaluating the perceived need for an institutional AC screening program. Based on an overwhelmingly positive response, we established a dedicated AC screening clinic (including provision of high-resolution anoscopies) embedded within the institutional HIV clinic. Here, we describe that referral of high-risk patients in the first 3 years was lower than expected. Referral patterns suggest that screening practices vary widely among HIV providers within the institution. Anal cancer clinic patients who completed a perception survey rated the value of AC screening as high, with perceived positive health impact, and identified their providers as the main source of information on AC and AC screening. Our findings imply remaining provider-related barriers to AC screening.

Abstract
BACKGROUND The progression rate and predictors of anal dysplastic lesions to squamous cell carcinoma of the anus remain unclear. Characterizing these parameters may help refine anal cancer screening guidelines. OBJECTIVE This study aimed to determine the rate of progression of high-grade anal dysplasia to invasive carcinoma in HIV-infected persons. DESIGN Using the Surveillance, Epidemiology, and End Results database linked to Medicare claims from 2000 to 2011, we identified HIV-infected subjects with incident anal intraepithelial neoplasia III. To estimate the rate of progression of anal intraepithelial neoplasia III to invasive cancer, we calculated the cumulative incidence of anal cancer in this cohort. We then fitted Poisson models to evaluate the potential risk factors for incident anal cancer. SETTINGS This is a population-based study. PATIENTS Included were 592 HIV-infected subjects with incident anal intraepithelial neoplasia III. MAIN OUTCOME MEASURES The primary outcome measured was incident squamous cell carcinoma of the anus. RESULTS Study subjects were largely male (95%) with a median age of 45.7 years. Within the median follow-up period of 69 months, 33 subjects progressed to anal cancer. The incidence of anal cancer was 1.2% (95% CI, 0.7%-2.5%) and 5.7% (95% CI, 4.0%-8.1%) at 1 and 5 years, following a diagnosis of anal intraepithelial neoplasia III. Risk of progression did not differ by anal intraepithelial neoplasia III treatment status. On unadjusted analysis, black race (p = 0.02) and a history of anogenital condylomata (p = 0.03) were associated with an increased risk of anal cancer incidence, whereas prior anal cytology screening was associated with a decreased risk (p = 0.04). LIMITATIONS The identification of some incident cancer episodes used surrogate measures. CONCLUSIONS In our population-based cohort of HIV-infected subjects with long-term follow-up, the risk of progression from anal intraepithelial neoplasia III to anal squamous cell carcinoma was higher than reported in other studies and was not associated with the receipt of anal intraepithelial neoplasia III treatment.

Abstract
The incidence of anal squamous cell carcinoma (ASCC) in the U.S. is increasing, particularly in immunocompromised patients. Preventative screening is used to monitor precancerous dysplasia known as anal intraepithelial neoplasia (AIN), which can progress to ASCC. High Resolution Anoscopy (HRA) is one screening procedure that uses a colposcope with acetic acid and Lugol's iodine solution to visualize the anal epithelium for AIN. HRA has offered potential in managing AIN, but as more evidence emerges it is unclear whether HRA provides definitive benefit. This narrative review updates readers on the efficacy of HRA in screening AIN, compares HRA to other techniques, compares the use of HRA in various high-risk populations, and offers practical information on the use of HRA. Keyword searches were conducted using MEDLINE, Web of Science, and Cochrane Library. Current literature is mixed regarding the utility of HRA. Further randomized controlled trials are needed to definitively assess the role of HRA.

Abstract
The incidence of anal intraepithelial neoplasia (AIN) has been increasing over the years. AIN acts as a precursor lesion for anal squamous cell cancer. Factors leading to progression of AIN into malignancy are complex and involve grade of the lesion, human papillomavirus and HIV coinfection, as well as patient-related risk factors such as immunocompromised state and men who have sex with men. The multifaced aspects of this disease make its management challenging, as it involves several disciplines including pathology, primary care, infectious disease, and colorectal specialties. Each of these fields brings its own expertize to the management of AIN, and their collaborative, coordinated work culminates into best practice and optimized outcomes in the care of the AIN patient.

Abstract
High-resolution anoscopy (HRA) is a form of low-resolution anal microscopy currently utilized in the screening and management of anal squamous dysplasia. No randomized controlled trials, national or international guidelines exist on the use of HRA for this purpose. Much of our understanding of this entity has been adapted from the literature on cervical squamous dysplasia, including the technique of HRA itself. Epidemiologic evidence has shown that the prevalence and incidence of anal dysplasia is highest in HIV-positive populations. The history of this technique parallels the evolution of our understanding of anal dysplasia. To understand the history of the use of HRA and its place in the screening and management of anal squamous dysplasia, we discuss key advances in the understanding of human papillomavirus-related squamous dysplasia. We begin with early reports in the field establishing the link between this virus and squamous dysplasia, through the marked increase in anal cancer seen with the onset of the HIV epidemic, the identification of relevant populations at risk, the performance of the test itself, to its use today.

Abstract
Anal dysplasia can lead to anal cancer, which affects persons living with HIV (PLWH) more than people in the general population. Screening for anal dysplasia is recommended to detect anal cancer at an early stage. The aim of our process improvement project was to improve compliance and consistency in implementing anal dysplasia screening for PLWH receiving care at a Ryan White facility covering 18 counties in western North Carolina. There were 291 PLWH screened for anal dysplasia during the 9-month data-gathering period. The compliance rate significantly increased from a preintervention rate of 31.3% to 57.5% (p < .001). There were 109 (37.5%) abnormal screening results. PLWH who had abnormal screening results were more likely to be White. Gender and age were not significantly associated with abnormal screening results. Anal dysplasia screening is a simple procedure to detect precursors to cancer that can be integrated into the primary care of PLWH.

Abstract
AIM Potential screening modalities for early diagnosis of squamous cell anal cancer (SCC) in HIV patients include digital anorectal examination (DARE), anal Papanicolaou testing (Pap test), human papilloma virus (HPV) co-testing, and high-resolution anoscopy. The aim of this study was to demonstrate the results of a five-year screening program for SCC in HIV patients. MATERIALS AND METHODS We conducted a retrospective study on 204 HIV patients who underwent a screening program for SCC from October 2010 to January 2015. All patients were screened by DARE, anal Pap test, including HPV test and cytology, and high-resolution video-proctoscopy (HR-VPS) with and without acetic acid 3%. Depending on macroscopic appearance and biopsies, patients underwent observation or treatment. Median follow-up was 36 months. RESULTS Cytologic abnormalities (Cyt+) for high-risk HPV genotypes were recorded in 34% of patients. HR-VPS was positive in 59 patients (29%), of whom 13 patients (22%) were positive for warts; the rest have typical features of anal intraepithelial neoplasia (AIN). Sixteen (8%) patients had AIN (AIN I-III) and underwent wide local excision, ablation, or imiquimod. Absence of progression was recorded. Fourteen patients (7%) had SCC: eight (57%) with no evidence of recurrence, two (14%) had recurrence, and four (29%) died from metastatic disease. CONCLUSIONS Our data demonstrated a successful screening program in preventing SCC in HIV patients. We demonstrate the advantages of progression towards SCC. Moreover, we used a new screening tool, the HR-VPS, a low-cost and manageable instrument to collect patients' long-term data.

Abstract
Anal squamous cell carcinoma (SCC) is the fourth most prevalent cancer in human immunodeficiency virus (HIV)-infected men who have sex with men (MSM). Human papillomavirus (HPV) has been detected in over 90% of anal carcinoma biopsy specimens from MSM, and is considered a necessary, but alone, insufficient factor for carcinogenesis. Anal intraepithelial neoplasia (AIN) may be precursive for SCC, and screening cytology with referral of persons with abnormality for high-resolution anoscopy-guided biopsy, and AIN treatment, has been recommended for prevention. In the absence of either randomized controlled trials or surveillance data demonstrating a reduction in anal SCC incidence, these recommendations were based on analogy with cervical cancer. HPV-mediated genetic changes associated with cervical cancer, and aneuploidy, have been documented in AIN. However, little data exist on the rate of AIN progression to SCC. The treatment of AIN is frequently prolonged and not curative, and if routinized in the care of HIV-infected MSM, would likely be recurring well into their sixth decade of life. Clinical trials demonstrating a reduction in invasive anal carcinoma incidence, as well as acceptable morbidity with repeated AIN destruction, are needed before asking our patients to commit to routine treatment.

Abstract
Infection with certain types of human papillomavirus (HPV) has been associated with the development of cervical and anal cancer. Worldwide, the incidence of anal cancer has increased markedly. The present study aimed to evaluate the prevalence of HPV infection of the uterine cervix and anal canal in human immunodeficiency virus (HIV)- and non-HIV-infected risk populations. Cervical and anal HPV swabs and cytology samples were collected from 287 patients at the University Hospital of Munich, Germany between 2011 and 2013. Patients were divided into HIV-negative controls (G1) and two risk groups, including HIV-negative patients with cytological abnormalities of the cervix (G2) and HIV-infected patients (G3). Data, including clinical parameters, were analysed. The risk groups had significantly more positive results for HPV in the anus (71.03 and 83.15% for G2 and G3, respectively), as compared with G1. The predominant HPV genotypes found in the anus were high-risk HPV genotypes, which were significantly correlated with concomittant cervical HPV findings. In the risk groups, a significant association between the cytological findings and HPV detection in the cervix was found, while the results of the anus revealed no significance. The results of the present study suggested that the prevalence of HPV infection in the anal canal of risk populations is high. Furthermore, patients with abnormal cervical cytology results and HIV-infected women, irrespective of their individual cervical findings, may have a risk of concomittant anal high-risk HPV infection. Based on the predominant HPV genotypes found in the study, HPV vaccination could reduce the incidence of anal cancer. Nevertheless, high-risk patients should be intensively screened for anal squamous intraepithelial abnormalities to avoid invasive cancer stages.

Abstract
AIM Anal screening is recommended in HIV-positive patients, especially men who have sex with men (MSM), due to an increased incidence of anal cancer. The optimal screening methods are not generally agreed. METHOD Screening for anal lesions by anorectal examination, including anoscopy, was offered to HIV-positive outpatients in a tertiary care university hospital regardless of gender or sexual orientation. RESULTS Among the 1206 screened patients (701 MSM, 247 heterosexual men, 258 women), 311 (26%) had histologically proven lesions related to human papilloma virus (HPV) (34% MSM, 14% heterosexual men, 14% women); 123 (10%) had low-grade dysplasia and 70 (6%) high-grade dysplasia. Seven anal cancers were also diagnosed. Determinants of any lesion were age < 45 years [OR = 1.56 (95% CI, 1.16-2.11)], a CD4 count of < 200/mm3 [OR = 2.54 (1.71-3.78)], receptive anal intercourse [OR =3.03 (2.06-4.47)], sub-Saharan African origin [OR = 0.53 (0.33-0.85)], and history of HPV-related lesion [OR = 1.84 (1.35-2.51)]. These determinants were similar for all different grades of dysplasia. In patient subgroup analysis, receptive anal intercourse, the CD4 cell count and a history of HPV lesions were determinants of HPV-positivity in all patients, whereas age was only a determinant in men. CONCLUSION Anoscopy is an alternative method for anal screening in an HIV-positive population. This screening has to be compared with other tools in populations at high risk of anal cancer.

Abstract
Sexually transmitted infections are a resurgent problem in HIV disease. The number of new cases of syphilis among men who have sex with men has continued to increase, requiring renewed vigilance in screening, diagnosis, and treatment. Drug-resistant gonorrhea has prompted changes in treatment regimens and warrants continued monitoring. This article summarizes an IAS-USA continuing education webinar presented by Jeanne M. Marrazzo, MD, MPH, in January 2014.

Abstract
Squamous epithelial cells are susceptible to infection by the human papillomavirus. Infection of squamous epithelium with oncogenic human papillomavirus types is associated with development of dysplasia and potential malignant transformation. Historically, cervical cancer has been the most prevalent human papillomavirus-induced squamous neoplasia. However, because of widespread screening via Pap smear testing, rates of cervical cancer in the United States have decreased dramatically during the past 50 years. Rates of anal cancer, in contrast, have doubled during the past 30 years. The groups at highest risk for development of anal cancer are men who have sex with men, HIV-positive patients, and patients immunosuppressed as a result of solid-organ transplantation. By detecting dysplasia before it develops into invasive cancer, anal Pap smears may be a potentially useful screening tool for anal cancer, particularly in individuals known to be at increased risk. However, at this time, sufficient data supporting the benefit of anal Pap smear screening are lacking. With insufficient evidence, no national health care organizations currently recommend the use of anal Pap smears as a routine screening test, even among high-risk groups.

Abstract
BACKGROUND Anal carcinoma is increasing in high-risk populations. Dysplasia is often distributed throughout the anal mucosa, and focal ablative techniques have high rates of recurrence. METHODS With the goal of eradicating dysplasia from the entire anal mucosa, we conducted a phase I dose-ranging study to determine the safety and tolerability of radiofrequency ablation (RFA). HIV-infected individuals with high-grade anal intraepithelial neoplasia underwent RFA of the anal mucosa. Patient-reported procedural and postprocedural symptoms were recorded, and mucosal healing was visually assessed. RESULTS Four groups of 3 subjects each were treated with incrementally increasing numbers of RF pulses (1-3) applied to a single area of anal mucosa. Two or three doses of 12 J/cm2 were found to have acceptable patient tolerance and healing of the mucosa within 4 weeks of ablation. Using these doses, 2 groups underwent ablation of 180° of contiguous mucosa. Subjects experienced a loss of 1 to 3 days of daily activities of living, 7 to 14 days of postprocedure symptoms, and mucosal healing within 4 weeks. One subject in the first treatment group had the procedure aborted due to severe procedural pain. CONCLUSIONS The study provides evidence of the safety and tolerability of anal RFA of 180° of contiguous mucosa in a single procedure and will allow future RFA efficacy studies in the treatment of anal dysplasia.

Abstract
The incidence of anal cancer is increasing in the general population and especially in high-risk groups. A total of 90% of anal cancers are caused by human papilloma virus (HPV) infection of the anal canal. Similar to cervical cancer, anal cancer progresses through a predictable series of premalignant stages before resulting in invasive cancer; this process begins with persistent HPV infection. The HPV vaccine represents a promising strategy to combat the increasing incidence of anal cancer. Human Immunodeficiency Virus (HIV) predisposes people to persistent HPV infection, dysplasia, and subsequent anal cancer. Patients infected with HIV should be targeted for vaccination against HPV. There are difficulties in targeting this population, the most notable being that the optimal age for vaccination is prior to identification with any high-risk groups. Universal vaccination against HPV represents the best strategy to achieve maximum protection against anal cancer in high-risk groups.

Abstract
Anal squamous cell cancer is an uncommon malignancy caused by infection with oncogenic strains of Human papilloma virus. Anal cancer is much more common in immunocompromised persons, including those infected with Human immunodeficiency virus. High-grade anal intraepithelial neoplasia (HGAIN), the precursor of anal cancer, is identified by clinicians providing care for patients with anorectal disease, and is increasingly being identified during screening of immunosuppressed patients for anal dysplasia. The traditional treatment for HGAIN has been excision of macroscopic disease with margins. This approach is effective for patients with small unifocal HGAIN lesions. Patients with extensive multifocal HGAIN frequently have recurrence of HGAIN after excision, and may have postoperative complications of anal stenosis or fecal incontinence. This led to the suggestion by some that treatment for HGAIN should be delayed until patients developed anal cancer. Alternative approaches in identification and treatment have been developed to treat patients with multifocal or extensive HGAIN lesions. High-resolution anoscopy combines magnification with anoscopy and is being used to identify HGAIN and determine treatment margins. HGAIN can then be ablated with a number of modalities, including infrared coagulation, CO2 laser, and electrocautery. These methods for HGAIN ablation can be performed with local anesthesia on outpatients and are relatively well tolerated. High-resolution anoscopy-directed HGAIN ablation is evolving into a standard approach for initial treatment and then subsequent monitoring of a disease which should be expected to be recurrent. Another treatment approach for HGAIN is topical treatment, principally with 5-fluorouracil or imiquimod. Topical therapies have the advantage of being nonsurgical and are well suited for treating widespread multifocal disease. Topical treatments have the disadvantage of requiring extended treatment courses and causing a symptomatic inflammatory response. Successful treatment requires adherence to a regime that is uncomfortable at best and at worst painful. Topical treatments can be successful in motivated adherent patients willing to accept these side effects.
