Abstract
Background Anal cancer disproportionately affects sexual and gender minority individuals living with HIV. High-resolution anoscopy (HRA) is an in-clinic procedure to detect precancerous anal lesions and cancer, yet prospective data on factors associated with HRA attendance are lacking. We examined whether anal HPV sampling at home versus in a clinic impacts HRA uptake and assessed HRA acceptability. Methods Sexual and gender minority individuals were randomised to home-based self-sampling or clinical sampling. All were asked to attend in-clinic HRA 1year later. We regressed HRA attendance on study arm using multivariable Poisson regression and assessed HRA acceptability using χ 2 tests. Results A total of 62.8% of 196 participants who engaged in screening attended HRA. Although not significant (P =0.13), a higher proportion of participants who engaged in clinic-based screening attended HRA (68.5%) compared to home-based participants (57.9%). Overall, HRA uptake was higher among participants with anal cytology history (aRR 1.40, 95% CI 1.07-1.82), and lower among participants preferring a versatile anal sex position versus insertive (aRR 0.70, 95% CI 0.53-0.91), but did not differ by race or HIV serostatus. In the clinic arm, persons living with HIV had lower HRA attendance (42.9%) versus HIV-negative participants (73.3%) (P =0.02) and Black non-Hispanic participants had lower HRA attendance (41.7%) than White non-Hispanic participants (73.1%), (P =0.04). No differences in attendance by race or HIV status were observed in the home arm. Conclusions HRA uptake differed significantly by race and HIV status in the clinic arm but not the home arm.

Abstract
BACKGROUND Anal cancer (AC) disproportionally affects people living with HIV (PLWH). Although there are no consensus-based AC screening guidelines, experts recommend anal pap as a primary screening tool in settings where high-resolution anoscopy (HRA) is available. We aimed to assess barriers and facilitators to anal cancer screening in a sample of Hispanic PLWH in Puerto Rico. METHODS To assess their knowledge and attitudes, we conducted a cross-sectional survey from 2020-2021 among PLWH in Puerto Rico (n = 212). Data was collected through a telephone interview that assessed information on sociodemographics, knowledge, and attitudes about AC, and the history of AC screening. The chi-square test, Fisher exact test, and logistic regression models were used to assess factors associated with screening uptake. RESULTS Anal Pap and HRA awareness were 60.4% and 30.7%, respectively. Anal Pap and HRA uptake was 51.5% and 19.3%, respectively. The most common barriers for anal Pap and HRA were lack of knowledge about the test and lack of physician recommendation. MSM were more likely to have heard of anal Pap (OR: 2.15, 95% CI:1.30-3.54) than MSW. MSM (OR: 3.04, 95% CI: 1.79-5.19) and women (OR: 3.00, 95% CI: 1.72-5.20) were also more likely to have undergone anal Pap. Similarly, individuals with a history of genital warts were more likely to have heard of anal Pap and HRA and have undergone anal Pap and HRA. Awareness of where to go for concerns about anal health was positively associated with having received anal Pap and HRA. CONCLUSIONS With emerging evidence on the effectiveness of screening and treatment for anal cancer, several organizations are steering toward generating consensus-based anal cancer screening recommendations. Our study provides foundational data on barriers and facilitators to anal cancer screening in Puerto Rico that will be critical to informing screening implementation in this US territory.

Evaluation of the validity of the HPV viral load compared to conventional techniques for the detection of high-grade anal intraepithelial lesions in men with HIV who have sex with men. PeerJ 2023; 11:e15878. [PMID: 37637161 PMCID: PMC10460151 DOI: 10.7717/peerj.15878] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/15/2023] [Accepted: 07/18/2023] [Indexed: 08/29/2023] Open
Abstract
Background The incidence of high-grade anal intraepithelial lesions (HSILs) has increased in recent years among men who have sex with men with human immunodeficiency virus (HIV). This work evaluated the validity of the human papilloma virus viral load (HPV-VL) versus cytological and qualitative HPV results to detect HSILs. Methods From May 2017 to January 2020, 93 men who have sex with men and HIV were included in an anal cancer screening program from the Infectious Diseases Unit at a tertiary-care hospital in Alicante (Spain). The gold-standard for the screening of anal HSILs is the anal biopsy using high-resolution anoscopy. The diagnostic methods compared against gold-standard were HPV-16-VL, HPV-18-VL, and HPV-16-18-VL co-testing, anal cytology, and qualitative HPV detection. The receiver operating characteristic (ROC) curve and cut-off points for HPV-VL were calculated. The sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and Cohen's Kappa coefficient (κ) were also calculated. Results The mean patient age was 44.6 ± 9.5 years. All of them received antiretroviral treatment, 96.8% had an HIV viral load of <50 copies/mL and 17.2% had a previous diagnosis of AIDS. The diagnosis of the anal biopsies were: 19.4% (n = 18) HSIL, 29.1% (n = 27) LSIL, and 51.6% (n = 48) negative. An HPV-16-VL >6.2 copies/cell was detected in the HSIL biopsy samples (p = 0.007), showing a sensitivity of 100% and a specificity of 46.2%. HPV-18-VL and HPV16-18-VL co-testing showed a sensitivity of 75% and 76.9% and a specificity of 72.7% and 61.3%, respectively. The highest PPV was 50% obtained with the cytology and HPV-18-VL. The HPV-16-VL showed a NPV of 100%, followed by 88.9% in the HPV-18-VL and 87% in the abnormal cytology. Cohen's Kappa coefficient were: HPV-18-VL (κ = 0.412), abnormal cytology (κ = 0.353) and HPV-16-VL (κ = 0.338). Conclusions HPV-VL testing improved the detection sensitivity but not the specificity for HSIL biopsies compared to anal cytology and the qualitative detection of HPV. In men who have sex with men and HIV the HPV-VL could be an useful tool for diagnosis of HSILs in anal cancer screening programs. Further studies will be needed to evaluate the clinical implications of HPV-VL in these programs.

Abstract
In developed countries the incidence of anal squamous cell carcinoma (SCC) has been rising; especially in women over the age of 60 years who present with more advanced disease stage than men. Historically, anal SCC screening has focused on people living with Human Immunodeficiency Virus (HIV) (PLWH) who are considered to be at the highest risk of anal SCC, and its precancerous lesion, anal squamous intraepithelial lesion (SIL). Despite this, women with vulval high-grade squamous epithelial lesions (HSIL) and SCCs have been shown to be as affected by anal HSIL and SCC as some PLWH. Nevertheless, there are no guidelines for the management of anal HSIL in this patient group. The ANCHOR trial demonstrated that treating anal HSIL significantly reduces the risk of anal SCC in PLWH, there is therefore an unmet requirement to clarify whether the screening and treatment of HSIL in women with a prior genital HSIL is also beneficial. This review presents the current evidence supporting the screening, treatment, and surveillance of anal HSIL in high-risk women with a previous history of genital HSIL and/or SCC.

Abstract
Background Prevalence of anal cancer is increasing among people with HIV (PWH). Screening for anal cancer involves evaluating cytology and biopsy with high-resolution anoscopy (HRA) if indicated. In this study, we sought to identify the prevalence of abnormal anal cytology and biopsy-proven high-grade dysplasia, defined as anal intraepithelial neoplasia 2 and 3 (AIN2+). Methods Demographic and clinical data were collected from participants age ≥30 years with ≥1 anal Pap smear performed during the study period (12/18/2017-05/29/2021). A subgroup analysis was performed on those with ≥1 HRA. Logistic regression estimated adjusted odds ratios (aORs) for variables of interest such as age, race, gender, presence of HPV strains, and sexual practices. Results Of 317 participants, 48% (n = 152) had abnormal cytology (93% low-grade squamous intraepithelial lesion [SIL] or atypical cells of undetermined significance [ASCUS] and 7% high-grade SIL). Most with abnormal cytology proceeded to HRA (n = 136/152). Of those with HRA, 62% (n = 84/136) had AIN2+. History of anoreceptive intercourse (aOR 4.62; 95% CI 1.08-23.09; P = .047), HPV 16 (aOR 4.13; 95% CI 1.63-11.30; P = .004), and "other" high-risk HPV strains (aOR 5.66; 95% CI 2.31-14.78; P < .001) were significantly associated with AIN2+. Conclusions Nearly half of those screened had abnormal cytology, highlighting the high prevalence of anal dysplasia in PWH. Though only 7% had high-grade SIL on cytology, 62% of those biopsied had AIN2+, suggesting that cytology underestimates the severity of dysplasia on biopsy. HPV 16 and "other" high-risk strains were associated with AIN2 + and could be considered for risk-stratifying patients in the screening algorithm.

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
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
The incidence of and mortality from anal cancer, predominantly squamous cell carcinoma (SCC), have been increasing since the 1980s, during an era when many common malignancies have seen decreases in mortality. Dermatologists may be more likely to see patients at an increased risk for anal SCC, such as those living with HIV, MSM and those presenting for management of anogenital warts, yet there is little guidance in the field on how to manage these patients. We underwent a project to review the evidence surrounding screening and prevention of anal SCC. HPV vaccination, the main preventative measure for anal SCC, is often underutilized and may not be effective for those most at risk. Screening methods currently include high-risk HPV and anal cytology testing, with high-resolution anoscopy (HRA) reserved for biopsy and confirmatory testing. High-risk HPV testing has been associated with high sensitivity for intraepithelial neoplasia, but low specificity in high-risk groups. Recent meta-analyses examining AIN detection using anal cytology estimate a similarly high sensitivity of 74-87%, with a relatively higher specificity (44-66%) for identifying high-grade AIN. HRA is the gold standard for diagnosis, but its accessibility and cost are deterrents from its use as a screening tool. Cervical cancer screening, initially adopted without significant evidence of its impact, has significantly decreased cervical cancer rates. The argument can be made that rates of anal SCC may also benefit from appropriate screening methods, particularly anal cytology. It is prudent for dermatologists to be aware of the methods available to them in the management of at-risk patients, the data supporting them, and the potential benefits of screening in order to counsel patients appropriately and address the increasing burden of disease.

Abstract
BACKGROUND Our objective was to quantify the extent of anal cancer screening among men receiving HIV specialty care in Ontario, Canada, and evaluate factors associated with screening. SETTING Cross-sectional questionnaire within a multisite clinical HIV cohort. METHODS A questionnaire assessing knowledge and experience with human papillomavirus-associated diseases and their prevention was administered in 2016-2017 to 1677 men in the Ontario HIV Treatment Network Cohort Study. We used logistic regression to identify factors associated with having discussed screening with a health care provider and self-reported receipt of screening [digital anal rectal examinations (DARE); anal cytology or anoscopy]. Results reported as adjusted odds ratios (aORs) with 95% confidence intervals (CIs). RESULTS Forty percent of men reported ever having had anal cytology/anoscopy, and 70% had ever had DARE. After accounting for differences in age, sexual orientation, years since HIV diagnosis, previous diagnosis with AIDS, knowing someone with human papillomavirus-associated cancer, comfort discussing anal health, education, and income, the proportion screened differed by self-identified race. Compared with white men, Asian men were less likely to have discussed screening with a health care provider (aOR = 0.48; 95% CI: 0.29 to 0.80) or to have been screened by DARE (aOR = 0.27; 95% CI: 0.17 to 0.44) or anal cytology/anoscopy (aOR = 0.51; 95% CI: 0.31 to 0.83), and African, Caribbean, or black men (aOR = 0.47; 95% CI: 0.31 to 0.70) were less likely to have had DARE. Results were consistent when restricting the analyses to gay, bisexual, and other men who have sex with men. CONCLUSION Our findings highlight the potential for disparities in anal cancer screening that need to be considered when developing guidelines and screening programs to reduce the burden of anal cancer among men living with HIV and ensure health equity.

Abstract
Gay, bisexual, and other men who have sex with men (MSM) experience disproportionately high burdens of Human Papilloma Virus (HPV)-associated anal cancers. Recent focus has shifted to anorectal cancer prevention through high-resolution anoscopy (HRA); however, little is known about sexual minority men's perceptions, attitudes, or beliefs regarding HRA. We conducted 4 qualitative Focus Group Discussions (FGDs) (n = 15) with sexual minority men, focusing on their beliefs, attitudes, and perceptions of undergoing HRA. Participants discussed their experiences of HPV/HRA as influenced by both their gender and sexuality, including unawareness of HPV disease as a male health issue, challenges relating to female-oriented HPV/HRA language, conception of HPV/HRA as related to prostate health, and connecting their sexual behavior identification as "bottoms" to their need for HRA. As efforts to improve HRA knowledge, access, and uptake among sexual and gender minority communities increase, special attention should be paid to language and messaging choices around HRA.

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
Abstract
Study objectives To perform anal lesion and anal cancer screening in men living with HIV/AIDS.
Methods This is a descriptive, observational, cross-sectional study. Data were obtained from the Specialized Assistance Service (SAE) in Divinópolis, Minas Gerais. A sociodemographic, epidemiological, and sexual behavior questionnaire was applied; material was collected for cytology, high-resolution anoscopy (AAR) was performed, and an acceptability questionnaire applied.
Main results Of the 50 men living with HIV/AIDS invited to participate in this study, 6% were excluded because they were illiterate, 40% refused to participate, and 54% participated in the survey. Among these, all answered the self-administered questionnaire. However, ten (37.0%) underwent proctological examination and anal cytology. Of these, two did not respond to the acceptability questionnaire. No anal lesions were identified during AAR and no biopsy was required. A 10% change in anal cytology was found.
Conclusions Through the study it was possible to construct a flow of referrals from the SAE to the UFSJ Coloproctology outpatient clinic. Moreover, the existence of internal stigmas on the part of the participants regarding the proctological examination and the lack of information about anal cancer screening are challenges to be overcome.

Abstract
BACKGROUND Few studies have examined outcomes of high-resolution anoscopy (HRA)-based screening for people with HIV infection (PWH), a population at increased risk for anal cancer. SETTING Large integrated health care system. METHODS Cohort study of 13,552 people with HIV infection, comparing incidences of anal cancer and advanced anal cancer (higher stage, recurrence, death, or surgical salvage) before and after HRA became available (2008). Calendar time was divided as 1998-2007, 2008-2010, and 2011-2012. Rate ratios (RRs) were obtained from Poisson regression models with adjustment for baseline demographic and health variables. Cohort cases during 2008-2012 were included in a nested case-control study, evaluating association of screening with anal cancer (33 cases, 330 controls) and advanced anal cancer (19 cases, 190 controls). Odds ratios (ORs) for receipt of screening were obtained from conditional logistic regression models with adjustment for baseline demographic and health history variables. RESULTS Compared with 1998-2007 (pre-HRA), 2008-2010 adjusted RRs were 1.32 [95% confidence intervals (CI): 0.77 to 2.27; P = 0.31] for anal cancer and 2.11 (95% CI: 0.99 to 4.48; P = 0.053) for advanced anal cancer; and 2011-2012 adjusted RRs were 0.35 (95% CI: 0.12 to 0.99; P = 0.048) for anal cancer and 0.23 (95% CI: 0.03 to 1.77; P = 0.16) for advanced anal cancer. Individual history of screening did not reach statistical significance for anal cancer (OR 1.7; 0.6-4.6) or advanced anal cancer (OR 0.44; 0.1-3.8). CONCLUSIONS Despite the possible effect of secular trends, we found 2008-2012 incidence trends for anal cancer and advanced anal cancer that seem consistent with expected findings of a beneficial screening program.

Abstract
Background Anal cancer is potentially preventable through screening. For screening to be implemented, the screening procedures must be acceptable to the affected population. The objective of the present study was to measure the acceptability of currently available anal cancer screening tests in a population of women living with hiv who had experienced the tests. Methods The evva study ("Evaluation of Human Immunodeficiency Virus, Human Papillomavirus, and Anal Intraepithelial Neoplasia in Women") is a prospective cohort study of adult women living with hiv in Montreal, Quebec. Participants were screened with cervical or anal hpv testing and cervical or anal cytology every 6 months for 2 years. High-resolution anoscopy (hra) and digital anal rectal examination (dare) were also performed systematically, with biopsies, at baseline and at 2 years. An acceptability questionnaire was administered at the final visit or at study withdrawal. Results Of 124 women who completed the acceptability questionnaire, most considered screening "an absolute necessity" in routine care for all women living with hiv [77%; 95% confidence interval (ci): 69% to 84%]. Yearly anal cytology or anal hpv testing was considered very acceptable by 81% (95% ci: 73% to 88%); hra every 2 years was considered very acceptable by 84% (95% ci: 77% to 90%); and yearly dare was considered very acceptable by 87% (95% ci: 79% to 92%). Acceptability increased to more than 95% with a longer proposed time interval. Pain was the main reason for lower acceptability. Conclusions Most participating women considered anal cancer screening necessary and very acceptable. Longer screening intervals and adequate pain management could further increase the acceptability of repeated screening.

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.
