Abstract
BACKGROUND Anal intraepithelial neoplasia grade III is a precursor to squamous cell carcinoma of the anus for which rates are nearly 20-fold higher in people with HIV than in the general population in the United States. We describe trends in anal intraepithelial neoplasia grade III diagnosis and risk of squamous cell carcinoma of the anus following anal intraepithelial neoplasia grade III by HIV status and sex. METHODS We used data from a population-based linkage between cancer and HIV registries in 11 US states; Puerto Rico; and Washington, DC, during 1996-2019. We identified all individuals with a diagnosis of anal intraepithelial neoplasia grade III and determined their HIV status. We estimated the average annual percentage change of anal intraepithelial neoplasia grade III using Poisson regression stratified by HIV status and sex. We estimated the 5-year cumulative incidence of squamous cell carcinoma of the anus following an anal intraepithelial neoplasia grade III diagnosis stratified by sex, HIV status, and prior AIDS diagnosis. RESULTS Among people with HIV, average annual percentage changes for anal intraepithelial neoplasia grade III were 15% (95% confidence interval [CI] = 12% to 17%) per year among females and 12% (95% CI = 11% to 14%) among males. Average annual percentage changes for those without HIV were 8% (95% CI = 7% to 8%) for females and 8% (95% CI = 6% to 9%) for males. Among people with HIV, a prior AIDS diagnosis was associated with a 2.7-fold (95% CI = 2.23 to 3.40) and 1.9-fold (95% CI = 1.72 to 2.02) increased risk of anal intraepithelial neoplasia grade III diagnosis for females and males, respectively. Five-year cumulative incidence of squamous cell carcinoma of the anus following anal intraepithelial neoplasia grade III for people with HIV with a prior AIDS diagnosis were 3.4% and 3.7% for females and males, respectively. CONCLUSIONS Rates of anal intraepithelial neoplasia grade III diagnoses have increased since 1996, particularly for people with HIV, likely influenced by increased screening. A prior AIDS diagnosis was strongly associated with risk of anal intraepithelial neoplasia grade III diagnosis.

Abstract
BACKGROUND Targeted ablation of anal canal high-grade dysplasia results in high recurrence over time. Circumferential radiofrequency ablation might decrease recurrence. OBJECTIVE This study aimed to determine the safety and efficacy of circumferential radiofrequency ablation for anal high-grade dysplasia. DESIGN This was a dual-center, prospective trial of circumferential radiofrequency ablation with a 1-year follow-up with longer follow-up data abstracted from medical records of study patients returning after trial for surveillance. Ten participants from the identically conducted pilot circumferential radiofrequency ablation trial were included to improve sample size for longer-term analysis. SETTINGS This study included 3 surgeons at 2 sites. PATIENTS The study included 51 patients undergoing circumferential radiofrequency ablation for anal canal high-grade dysplasia. INTERVENTION Circumferential radiofrequency ablation of anal canal high-grade dysplasia and targeted radiofrequency ablation of recurrence. MAIN OUTCOME MEASURES The primary outcome measures were circumferential radiofrequency ablation efficacy and associated morbidity. RESULTS Fifty-one participants underwent circumferential radiofrequency ablation but 48 participants returned for 1 or more postprocedure high-resolution anoscopy and were evaluable. The mean age of participants was 43 years, most were male (94%), 33% were living with HIV, and 58% had 3 or more high-grade dysplasias treated. Sixty percent had no recurrence, whereas 19% had 1 recurrence, 15% had 2 recurrences, and 6% had 3 recurrences. Most recurrences (66%) developed within the first 6 months. Kaplan-Meier probability of recurrence combining both series was 19% at 3 months, 30% at 6 months, and approximately 40% after 6 months out to 30 months. Most common morbidities were pain (85.4%) lasting for a median of 21 (range, 4-91) days and bleeding (91%) lasting for a median of 21 (range, 5-87) days. Of those with pain and bleeding, 65% and 85%, respectively, described it as mild. No patients developed fistulas, stricture, or incontinence. No serious adverse events related to circumferential radiofrequency ablation occurred. Having a previous recurrence was the only significant predictor of a subsequent recurrence (HR, 28.53) for recurrence at 9 months or before. LIMITATIONS Enrollment ended prematurely, 10 participants from the pilot study were combined to increase the sample size, and longer-term follow-up was collected retrospectively were the limitations of this study. CONCLUSIONS Circumferential radiofrequency ablation has improved efficacy over targeted ablation but with increased pain and bleeding. See Video Abstract at http://links.lww.com/DCR/B973 .

Diez participantes del estudio piloto de ablación por radiofrecuencia circunferencial realizada de manera idéntica, se combinaron para mejorar el análisis del tamaño de la muestra a largo plazo.PACIENTES:Se incluyeron 51 pacientes sometidos a la ablación por radiofrecuencia circunferencial de una lesion displásica de alto grado en el canal anal.AJUSTES:Tres cirujanos en 2 centros.INTERVENCIÓN:Ablación por radiofrecuencia circunferencial de la displasia de alto grado en el canal anal y ablación por radiofrecuencia dirigida de la recidiva.PRINCIPALES MEDIDAS DE RESULTADOS:Las medidas primarias fueron la eficacia de la ablación por radiofrecuencia circunferencial y la morbilidad asociada.RESULTADOS:Cincuenta y un participantes se sometieron a la ablación por radiofrecuencia circunferencial, de los cuales, 48 regresaron para ser evaluados con ≥1 anuscopias de alta resolución, después del procedimiento. La edad media de los participantes fue de 43 años, en su mayoría hombres (94%), el 33% eran portadores de VIH y el 58% tenía ≥3 lesiones displásicas de alto grado tratadas. El sesenta por ciento no tuvo recidiva, mientras que el 19%, 15% y 6% tuvieron 1, 2 o 3 recidivas. La mayoría de las recaídas (66%) se desarrollaron dentro de los primeros 6 meses. La probabilidad de recurrencia de Kaplan-Meier combinando ambas series fue del 19 % a los 3 meses, del 30 % a los 6 meses y aproximadamente del 40 % entre los 6 y 30 meses. Los indicadores de morbilidad más frecuentes fueron, el dolor (85,4%) con una mediana de duración de 21 días (rango, 4-91) y sangrado (91%) con una mediana de duración de 21días (rango, 5-87). Aquellos pacientes con dolor (65%) y sangrado (85%) respectivamente, los describieron como leves. Ningún paciente desarrolló fístula, estenosis o incontinencia. No se produjeron eventos adversos graves relacionados con la ablación por radiofrecuencia circunferencial. Tener una recurrencia previa fue el único factor predictivo importante de una recidiva ulterior (RH 28,53) en casos de recaída a los 9 meses o antes.LIMITACIONES:Como el registro finalizó prematuramente, se agregaron 10 participantes del estudio piloto para aumentar el tamaño de la muestra. El seguimiento a largo plazo fué recopilado retrospectivamente.CONCLUSIONES:La ablación por radiofrecuencia circunferencial ha mejorado la eficacia sobre la ablación dirigida pero con dolor y sangrado mas importantes.

Abstract
HPV, or Human Papilloma Virus, has been the primary causative agent of genital warts and cervical cancer worldwide. It is a sexually transmitted infection mainly affecting women of reproductive age group, also infecting men and high-risk group individuals globally, resulting in high mortality. In recent years, HPV has also been found to be the major culprit behind anogenital cancers in both gender and oropharyngeal and colorectal cancers. Few studies have reported the incidence of HPV in breast cancers as well. For a few decades, the burden of HPV-associated malignancies has been increasing at an alarming rate due to a lack of adequate awareness, famine vaccine coverage and hesitancy. The effectiveness of currently available vaccines has been limited to prophylactic efficacy and does not prevent malignancies associated with post-exposure persistent infection. This review focuses on the current burden of HPV-associated malignancies, their causes and strategies to combat the growing prevalence of the cancers. With the advent of new technologies associated with treatment pertaining to therapeutic interventions and employing effective vaccine coverage, the burden of this disease may be reduced in the population.

Abstract
Background Persons living with HIV (PLWH) are at high risk of developing anal high-grade squamous intraepithelial lesions (HSIL). We aimed to develop a prediction model for anal HSIL based on individual characteristics of PLWH. Methods Cross-sectional study of PLWH aged ≥21 years who attended the Anal Neoplasia Clinic of the University of Puerto Rico Comprehensive Cancer Center from 2016 to 2022. The primary outcome was biopsy-confirmed anal HSIL. For each sex, relations between potential predictors and HSIL were examined using univariate (ULRM) and multivariable (MLRM) logistic regression models. Risk modelling was performed with MLRM and validated with bootstrapping techniques. The area under the ROC Curves (AUC) was estimated with 95% CI. Findings HSIL was detected among 45.11% of patients, 68.48% were males, and 59.42% were ≥45 aged. Multivariable analysis showed that, in women, the only significant predictor for HSIL was having a previous abnormal anal cytology (p = 0.01). In men, significant predictors for HSIL were having a previous abnormal anal cytology (p < 0.001) and a history of infection with any gonorrhoea (p = 0.002). Other suggestive predictors for HSIL among women were obesity and smoking. No association between smoking and HSIL among men was observed (p < 0.05). The AUC estimated among women (0.732, 95% CI: 0.651-0.811) was higher than in men (0.689, 95% CI: 0.629-0.748). Interpretation Our results support that the inclusion of individual characteristics into the prediction model will adequately predict the presence of HSIL in PLWH.

Abstract
Background: Women living with human immunodeficiency virus (HIV), WLWHs, are at high risk of developing anal cancer associated with high-risk human papilloma virus infection (HR-HPV). We analyzed the prevalence of anal HR-HPV infection and abnormal anal cytology in a cohort of WLWHs and assessed the risk factors for anal HR-HPV infection. Methods: We present a single-center, observational cross-sectional study. WLWHs who underwent anal cytology and anal human papilloma virus (HPV) testing were selected. High-resolution anoscopy was performed in cases of abnormal anal cytology. All suspicious lesions were biopsied. A univariate and multivariate logistic regression model was used to analyze risk factors for abnormal anal screening. The results are presented as odds ratios (ORs) and 95% confidence intervals (CIs). Results: In total, 400 WLWHs were studied. Of them, 334 met the eligibility criteria and were enrolled in the study. Abnormal anal cytology was detected in 39.5% of patients, and anal HR-HPV in 40.1%, with HPV 16 in 33 (26.6%) of them. Concomitant HR-HPV cervical infection was the only independent risk factor for HR-HPV anal infection (OR 1.67 95% CI, p < 0.001). Conclusions: WLWHs have a high prevalence of HR-HPV anal infection and anal cytologic abnormalities. HR-HPV cervical infection is the main predictor of HR-HPV anal infection.

Abstract
Current expert recommendations suggest anal cytology followed by high-resolution anoscopy (HRA) for biopsy and histological confirmation may be beneficial in cancer prevention, especially in people living with HIV (PLWH). Guided by the social ecological model, the purpose of this study was to examine sociodemographic and clinical variables, individual-level factors (depression, HIV/AIDS-related stigma, and health beliefs) and interpersonal-level factors (social support) related to time to HRA follow-up after abnormal anal cytology. We enrolled 150 PLWH from a large HIV community clinic, with on-site HRA availability, in Atlanta, GA. The median age was 46 years (interquartile range of 37-52), 78.5% identified as African American/Black, and 88.6% identified as born male. The average length of follow-up to HRA after abnormal anal cytology was 380.6 days (standard deviation = 317.23). Only 24.3% (n = 39) of the sample had an HRA within 6 months after an abnormal anal cytology, whereas 57% of the sample had an HRA within 12 months. HIV/AIDS-related stigma [odds ratio (OR) 0.54, 95% confidence interval (CI) 0.33-0.90] and health motivation (OR 0.80, 95% CI 0.67-0.95) were associated with time to HRA follow-up ≤6 months. For HRA follow-up ≤12 months, we found anal cytology [high-grade squamous intraepithelial lesions/atypical squamous cells of undetermined significance cannot exclude HSIL (HSIL/ASCUS-H) vs. low-grade squamous intraepithelial lesions (LSIL) OR = 0.05, 95% CI 0.00-0.70; atypical squamous cells of undetermined significance (ASCUS) vs. LSIL OR = 0.12, 95% CI 0.02-0.64] and health motivation (OR = 0.86, 95% CI 0.65-0.99) were associated. Findings from this study can inform strategies to improve follow-up care after abnormal anal cytology at an individual and interpersonal level in efforts to decrease anal cancer morbidity and mortality.

Abstract
BACKGROUND Anal cancer disproportionately affects people with HIV (PWH). High-grade squamous intraepithelial lesions (HSIL) are cancer precursors and treating them might prevent anal cancer. Data on adherence to HSIL treatment and surveillance is limited but needed to identify deficiencies of screening strategies. METHODS We collected data on high-resolution anoscopy (HRA) attendance and outcomes from 2009 to 2019 in a large urban anal cancer-screening program. Patients with an initial HSIL diagnosis were followed for return for HSIL electrocautery ablation within 6 months of index HSIL diagnosis, and follow-up HRA within 18 months of index HSIL diagnosis. We also evaluated predictors of these outcomes in univariable and multivariable analyses. RESULTS One thousand one hundred and seventy-nine unique patients with an anal HSIL diagnosis were identified and 684 (58%) returned for electrocautery ablation. Of those treated, only 174 (25%) and only 9% of untreated HSIL patients (47 of 495) underwent surveillance HRA within 18 months of index HSIL diagnosis. In multivariable analyses, black patients and PWH regardless of virologic control were less likely to undergo HSIL ablation within 6 months of HSIL diagnosis whereas patients with commercial insurance were more likely to be treated within 6 months of diagnosis. Among treated HSIL patients, PWH with viremia had a lower likelihood of engaging in post-treatment surveillance within 18 months of HSIL diagnosis. DISCUSSION Even in large specialized anal cancer screening programs adherence to HSIL treatment and surveillance is low. Psychosocial and economic determinants of health may impact retention in care. Addressing both personal and structural barriers to patient engagement may improve the effectiveness of anal cancer screening.

Abstract
BACKGROUND Gay and bisexual men (GBM) are disproportionately affected by anal cancer. Prevention is hindered by incomplete understanding of the natural history of its precursor, anal high-grade squamous intraepithelial lesions (HSIL). METHODS The Study of the Prevention of Anal Cancer, conducted between 2010 and 2018, enrolled human immunodeficiency virus (HIV)-positive and HIV-negative GBM aged ≥35 years. Anal cytology and high-resolution anoscopy (HRA) were performed at baseline and 3 annual visits. A composite HSIL diagnosis (cytology ± histology) was used. Cytological high-grade squamous intraepithelial lesions (cHSIL) incidence and clearance rates were calculated with 95% confidence intervals (CIs). Predictors were calculated using Cox regression with hazard ratios (HRs) and 95% CIs. RESULTS Among 617 men, 220 (35.7%) were HIV-positive, median age 49 years. And 124 incident cHSIL cases occurred over 1097.3 person-years (PY) follow-up (11.3, 95% CI 9.5-13.5 per 100 PY). Significant bivariate predictors of higher incidence included age <45 years (HR 1.64, 95% CI 1.11-2.41), HIV positivity (HR 1.43, 95% CI .99-2.06), prior SIL diagnosis (P-trend < .001) and human papillomavirus (HPV)16 (HR 3.39, 2.38-4.84). Over 695.3 PY follow-up, 153 HSIL cleared (clearance 22.0, 95% CI 18.8-25.8 per 100 PY). Predictors were age < 45 years (HR 1.52, 1.08-2.16), anal intraepithelial neoplasia (AIN)2 rather than AIN3 (HR 1.79, 1.29-2.49), smaller lesions (HR 1.62, 1.11-2.36) and no persistent HPV16 (HR 1.72, 1.23-2.41). There was 1 progression to cancer (incidence 0.224, 95% CI .006-1.25 per 100 PY). CONCLUSION These data strongly suggest that not all anal HSIL detected in screening requires treatment. Men with persistent HPV16 were less likely to clear HSIL and are more likely to benefit from effective HSIL treatments.

Abstract
Anal squamous cell carcinoma is the most common type of anal cancer and is largely associated with anal human papillomavirus infection. The incidence of anal squamous cell carcinoma is increasing, and although still uncommon in the general population, a high incidence has been noted in specific population groups (eg, patients with HIV, men who have sex with men [MSM], recipients of solid organ transplants, women with genital neoplasia, and patients with systemic lupus erythematosus or inflammatory bowel disease). The higher incidence among individuals who are HIV-positive makes anal squamous cell carcinoma one of the most common non-AIDS-defining cancers among HIV-positive individuals. Anal cancer screening in high-risk groups aims to detect high-grade squamous intraepithelial lesions, which are considered anal precancerous lesions, and for which identification can provide an opportunity for prevention. A blind anal cytology is normally the first screening method, and for patients with abnormal results, this approach can be followed by an examination of the anal canal and perianal area under magnification, along with staining-a technique known as high-resolution anoscopy. Digital anorectal examination can enable early anal cancer detection. Several societies are in favour of screening for HIV-positive MSM and recipients of transplants. There are no current recommendations for screening of anal precancerous lesions via endoscopy, but in high-risk groups, a careful observation of the squamocolumnar junction should be attempted. Several treatments can be used to treat high-grade squamous intraepithelial lesions, including argon plasma coagulation or radiofrequency ablation, which are largely limited by high recurrence rates. Gastroenterologists need to be aware of anal squamous cell carcinoma and anal precancerous lesions, given that patients at high risk are frequently encountered in the gastroenterology department. We summarise simple procedures that can help in early anal squamous cell carcinoma detection.

Abstract
Background The objective of this study in MSM living with HIV was to determine the incidence of HSIL and ASCC, related factors, and the response to treatment. Patients and methods Data were gathered in 405 consecutive HIV-infected MSM (May 2010-December 2018) at baseline and annually on: sexual behavior, anal cytology, and HPV PCR and/or high-resolution anoscopy results. They could choose mucosectomy with electric scalpel (from May 2010) or self-administration of 5% imiquimod 3 times weekly for 16 weeks (from November 2013). A multivariate logistic regression model was developed for ≥HSIL-related factors using a step-wise approach to select variables, with a significance level of 0.05 for entry and 0.10 for exit, applying the Hosmer-Lemeshow test to assess the goodness of fit. Results The study included 405 patients with a mean age of 36.2 years; 56.7% had bachelor´s degree, and 52.8% were smokers. They had a mean of 1 (IQR 1–7) sexual partner in the previous 12 months, median time since HIV diagnosis of 2 years, and mean CD4 nadir of 367.9 cells/uL; 86.7% were receiving ART, the mean CD4 level was 689.6 cells/uL, mean CD4/CD8 ratio was 0.77, and 85.9% of patients were undetectable. Incidence rates were 30.86/1,000 patient-years for ≥high squamous intraepithelial lesion (HSIL) and 81.22/100,000 for anal squamous cell carcinoma (ASCC). The ≥HSIL incidence significantly decreased from 42.9% (9/21) in 2010 to 4.1% (10/254) in 2018 (p = 0.034). ≥HSIL risk factors were infection with HPV 11 (OR 3.81; 95%CI 1.76–8.24), HPV 16 (OR 2.69, 95%CI 1.22–5.99), HPV 18 (OR 2.73, 95%CI 1.01–7.36), HPV 53 (OR 2.97, 95%CI 1.002–8.79); HPV 61 (OR 11.88, 95%CI 3.67–38.53); HPV 68 (OR 2.44, CI 95% 1.03–5.8); low CD4 nadir (OR1.002; 95%CI 1–1.004) and history of AIDS (OR 2.373, CI 95% 1.009–5.577). Among HSIL-positive patients, the response rate was higher after imiquimod than after surgical excision (96.7% vs 73.3%, p = 0.009) and there were fewer re-treatments (2.7% vs 23.4%, p = 0.02) and adverse events (2.7% vs 100%, p = 0.046); none developed ASCC. Conclusions HSIL screening and treatment programs reduce the incidence of HSIL, which is related to chronic HPV infection and poor immunological status. Self-administration of 5% imiquimod as first-line treatment of HSIL is more effective than surgery in HIV+ MSM.

Abstract
Anal intraepithelial neoplasia (AIN) and 89-100% of anal cancers are caused by persistent infections with high-risk (HR) human papillomaviruses (HPV). In HIV-positive patients, anal HPV infection and AIN are very common and these patients have a significantly increased risk for anal cancer. However, a continuous increase in the incidence of anal cancer has also been observed in the general population in recent decades. AIN can clinically present in diverse manners. In HIV-positive patients AIN can be hidden in condylomas. Approximately 3-14% of high-grade AIN progress to anal cancer within 5 years. Therefore, screening examinations should be offered to patients with an increased risk for anal cancer. The treatment options for AIN are similar to those for condylomas. HIV-positive patients with controlled immune status and HIV-negative patients with anal cancer respond comparably well to combined radiochemotherapy. A German-language S3 guideline for anal cancer will be available in 2020. In HIV-positive patients over 26 years of age, HPV vaccination showed no effect in a controlled phase‑3 study. To prevent AIN and anal cancer in the future, HPV vaccination rates need to be increased in HPV-naïve girls and boys.

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
PURPOSE OF REVIEW Although human papillomavirus (HPV)-related anal squamous cell cancer (ASCC) is rare, its incidence has been rising and in high-risk populations exceeds the incidence of cancers for which screening programs are implemented. Therefore, targeted screening techniques are being evaluated with high-resolution anoscopy (HRA) as the current gold standard because of its ability to detect anal intraepithelial dysplasia (AIN) and premalignant high-grade squamous intraepithelial lesions (HSILs). However, a scarcity of trained providers presents a barrier to screening. RECENT FINDINGS ASCC incidence is rising especially in elderly women and young black men. Premalignant HSIL may not only progress to ASCC but also regress. Biomarkers such as HPV type, p16 immunostaining and DNA methylation markers may emerge as predictors of disease progression.HRA with acetic acid and Lugol's iodine staining can be used to detect HSIL and ASCC. Recent studies suggest that anal cancer screening may have an impact on the stage of ASCC at diagnosis and the incidence of anal cancer.The Anal Cancer HSIL Outcomes Research (ANCHOR) study is underway to determine whether treating HSIL effects ASCC incidence. SUMMARY Although there are no consensus screening guidelines for anal cancer, it is reasonable to screen high-risk populations with physical examination, anal cytology and HRA. Gastroenterologists can support anal cancer screening programmes through identifying patients at risk, performing noninvasive screening and considering to incorporate endoscopic techniques to examine the anal canal.

Abstract
PURPOSE To describe the regional burden of AIN and rate of progression to cancer in patients managed in specialist and non-specialist clinic settings. METHODS Patients with a histopathological diagnosis of AIN between 1994 and 2018 were retrospectively identified. Clinicopathological characteristics including high-risk status (chronic immunosuppressant use or HIV positive), number and type of biopsy (punch/excision) and histopathological findings were recorded. The relationship between clinicopathological characteristics and progression to cancer was assessed using logistic regression. RESULTS Of 250 patients identified, 207 were eligible for inclusion: 144 from the specialist and 63 from the non-specialist clinic. Patients in the specialist clinic were younger (<40 years 31% vs 19%, p = 0.007), more likely to be male (34% vs 16%, p = 0.008) and HIV positive (15% vs 2%, p = 0.012). Patients in the non-specialist clinic were less likely to have AIN3 on initial pathology (68% vs 79%, p = 0.074) and were more often followed up for less than 36 months (46% vs 28%, p = 0.134). The rate of progression to cancer was 17% in the whole cohort (20% vs 10%, p = 0.061). On multivariate analysis, increasing age (OR 3.02, 95%CI 1.58-5.78, p < 0.001), high risk status (OR 3.53, 95% CI 1.43-8.74, p = 0.006) and increasing number of excisions (OR 4.88, 95%CI 2.15-11.07, p < 0.001) were related to progression to cancer. CONCLUSION The specialist clinic provides a structured approach to the follow up of high-risk status patients with AIN. Frequent monitoring with specialist assessments including high resolution anoscopy in a higher volume clinic are required due to the increased risk of progression to anal cancer.

Abstract
Background Anal squamous cell carcinoma (ASCC) is one of the most frequent non-AIDS-defining neoplasias in HIV patients, mainly in MSM, and it has been associated with chronic infection with high-risk human papilloma virus (HR-HPV). Our main objective was to determine HR-HPV clearance and acquisition rates and related factors and their relationship with the incidence of HSILs and ASCC in anal mucosa of HIV+ MSM. Patients and methods The study included consecutive HIV-infected MSM between May 2010 and December 2018. Data were gathered at baseline and annually on their sexual behavior, CD4 and CD8 levels, plasma HIV viral load, and results of anal cytology, HPV PCR, and high-resolution anoscopy. Results Out of the 405 patients studied, 34.9% of patients cleared oncogenic genotypes (IQR: 37–69) within 49 months, and 42.9% acquired new genotypes within 36 months (IQR:12–60). In multivariate analysis, clearance was only significantly influenced by the duration of antiretroviral therapy (ART) (OR: 1.016, 95% CI 1.003–1.030). The incidence of HSILs was 30.86/1,000 patient-years and that of ASCC was 81.22/100,000 patient-years; these incidences were not influenced by the acquisition (acquired: 14.9% vs. non-acquired: 10.4%; p = 0.238) or clearance (cleared 11.4% vs. non-cleared: 13.2%; p = 0.662) rates of these viruses. Conclusions The duration of ART appears to positively affect oncogenic genotype clearance in the anal mucosa of HIV+ MSM, although this clearance does not affect the incidence of HSILs or ASCC. The reduction in HSIL+ rate observed in our patients may be attributable to the bundle of measures adopted at our center.

Abstract
BACKGROUND Human papillomavirus (HPV) is associated with the majority of anal high-grade intraepithelial neoplasia (AIN) and anal cancers. Little is known about the risk of anal cancer following a diagnosis of benign anal disease and AIN. METHODS Using data from nationwide, population-based Danish registries, a cohort of 126,174 individuals with either non-neoplastic anal disease or AIN 1 to 3 during 1970 to 2016 was followed until first occasion of anal cancer. Information on HIV status was obtained from the Danish HIV Cohort Study. The absolute risk of anal cancer was estimated using the Aalen-Johansen estimator taking into account censoring at emigration and end of follow-up and competing risk at time of death. Standardized incidence ratios (SIR) for anal cancer among individuals with non-neoplastic anal disease, including inflammatory lesions, hemorrhoids, and polyps, were estimated in Poisson models. Sex-, age-, and calendar period-specific national population rates were estimated using the Danish National Pathology Registry. RESULTS Anal cancer risk increased with increasing severity of lesions, reaching 4% 5 years after diagnosis of AIN3. Even among those with non-neoplastic anal lesions, particularly inflammatory lesions, anal cancer risk was significantly higher than expected from Danish national anal cancer rates (SIR = 2.8; 95% confidence intervals, 2.3-3.2). The absolute 5-year risk of anal cancer following AIN3 was considerably higher among HIV-positive (14.1%) than HIV-negative (3.2%) individuals. CONCLUSIONS Anal cancer risk increases with increasing severity of lesions and is especially high among HIV-positive individuals. IMPACT Vaccination against HPV is important in the prevention of both high-grade AIN and anal cancer.

Abstract
Squamous cell carcinoma (SCC) of the anus is a human papilloma virus (HPV) related malignancy that is preceded by anal intraepithelial neoplasia (AIN) making this cancer, at least theoretically, a preventable disease. In the past 10 years the diagnosis, management and nomenclature of AIN has dramatically changed. Increased life expectancy in human immunodeficiency virus (HIV) positive patients due to highly active antiretroviral therapy (HAART) has caused an increase in the incidence of SCC of the anus. While many experts recommend screening and treatment of anal high-grade squamous intraepithelial lesion (HSIL), there is no consensus on the optimal management these lesions. Therefore, there is a need to review the current evidence on diagnosis and treatment of AIN and formulate recommendations to guide management. Surgeons who are members of the Italian Society of Colorectal Surgery (SICCR) with a recognized interest in AIN were invited to contribute on various topics after a comprehensive literature search. Levels of evidence were classified using the Oxford Centre for Evidence-based Medicine of 2009 and the strength of recommendation was graded according to the United States (US) preventive services task force. These recommendations are among the few entirely dedicated only to the precursors of SCC of the anus and provide an evidence-based summary of the current knowledge about the management of AIN that will serve as a reference for clinicians involved in the treatment of patients at risk for anal cancer.
