Facilitators of and barriers to high-resolution anoscopy adherence among men who have sex with men: a qualitative study

Barriers and facilitators to anal cancer screening among men who have sex with men: a systematic review with narrative synthesis

BACKGROUND

Increasing trends of anal cancer among men who have sex with men (MSM) highlight the importance of anal cancer screening. However, the screening rate of anal cancer among MSM remains relatively low. This systematic review aims to identify and critically evaluate studies examining barriers and facilitators influencing MSM's participation in anal cancer screening.

METHODS

Systematic searches were performed in five databases (Web of Science, Medline, Embase, PsycINFO, and CINAHL). Evidence from qualitative, quantitative, and mixed methods studies was extracted and synthesized. Mixed Methods Appraisal Tool (MMAT) was used for quality assessment. Two researchers underwent selection and appraisal independently. PROSPERO registration number: CRD42024601449.

RESULTS

305 studies were identified with a total of 32 studies included, including 11 qualitative studies, 18 quantitative studies, and 3 mixed methods studies. The barriers and facilitators to anal cancer screening were categorized into four domains: individual factors, healthcare system factors, healthcare provider factors, and screen-related factors. Among the four domains, the most frequently reported barriers and facilitators to anal cancer screening were individual factors. A lack of knowledge about the risks of HPV, anal cancer, and anal screening (n = 16) was the most significant barrier. In contrast, a greater perceived understanding of anal cancer and screening (n = 6) was identified as the primary facilitator.

CONCLUSIONS

This systematic review provided a comprehensive assessment of barriers and facilitators to anal cancer screening among MSM, highlighting the need for targeted comprehensive intervention programs to enhance acceptance of screening. Implementing effective strategies to address potential barriers and promote facilitators across all domains of public health could significantly increase screening uptake.

Challenges in the implementation of a high-resolution anoscopy clinic for people with HIV in an oncologic center in Mexico City

BACKGROUND

Anal cancer incidence is increased in people with HIV (PWH), up to 60 times higher in men who have sex with men, and almost 15 times higher among women with HIV. Screening and treating high-grade lesions (HSIL) have proven to reduce the incidence of invasive anal cancer. In 2020, we started implementing a high-resolution anoscopy (HRA) clinic at INCan, a tertiary care oncologic center, as part of a screening program for PWH from the HIV clinic.

OBJECTIVES

We describe the barriers and difficulties in implementing an HRA Clinic from January 2020 to April 2021, including physician training, the certification process, discrepancies between cytology and histopathologist results, and the lack of experience of gastrointestinal pathologists in HPV-related lesions.

RESULTS

During the first 18 months of the HRA clinic implementation, 124 studies were performed, and 85 biopsies were done. The prevalence of HSIL was 22%. Initially, when a gastrointestinal pathologist reviewed anal canal biopsies, a second opinion was requested from a genitourinary pathologist who examined 72 of the biopsies; there were discrepancies in the diagnosis in 61% of the cases, with more advanced intraepithelial lesions in 43% of cases. Specifically, gastrointestinal pathologists missed 68% of HSILs. The difficulties we faced were not having access to adequate anoscopes. Training and certification are a long way to go. Also, women's reachability was low.

CONCLUSIONS

Diagnosis and management of anal HSIL have become a standard of care in the prevention of Anal Carcinoma in PWIH, the population with the highest incidence of this neoplasia. Implementing HRA programs requires correct supplies and equipment, which are not always locally available; investing in physicians' training and an experienced pathologist in HPV-associated lesions interpretation is also imperative. More advocacy is needed for HIV programs to incorporate and invest in anal cancer screening.

Engagement and Factors Associated With Annual Anal Human Papillomavirus Screening Among Sexual and Gender Minority Individuals

BACKGROUND

Although self-sampling could help address anal cancer screening barriers, no studies have investigated annual engagement with this method or compared it with annual screening with a provider. Building on our baseline article, we compared annual anal screening engagement between home-based self-sampling and clinic-based clinician sampling.

METHODS

The Prevent Anal Cancer Self-Swab Study recruited and randomized sexual and gender minority individuals 25 years and older who have sex with men to a home or clinic arm. Home-based participants were mailed an anal human papillomavirus self-sampling kit at baseline and 12 months, whereas clinic-based participants were asked to schedule and attend 1 of 5 participating clinics at baseline and 12 months. Using Poisson regression, we conducted an intention-to-treat analysis of 240 randomized participants who were invited to screen at both timepoints.

RESULTS

More than half (58.8%) of participants completed annual (median = 370 days) anal screening. In the home arm, 65.0% of participants engaged in annual screening compared with 52.5% of clinic-based participants ( P = 0.049). When stratified by HIV status, persons living with HIV had a higher proportion of home (71.1%) versus clinic (22.2%) annual screening ( P < 0.001). Non-Hispanic Black participants participated more in home-based annual anal screening (73.1%) than annual clinic screening (31.6%; P = 0.01). Overall, annual screening engagement was significantly higher among participants who had heard of anal cancer from an LGBTQ organization, reported "some" prior anal cancer knowledge, preferred an insertive anal sex position, and reported any prior cancer diagnosis.

CONCLUSIONS

Annual screening engagement among those at disproportionate anal cancer risk was higher in the home arm.

Predictors of Resolution and Recurrence of Anal High-Grade Squamous Intraepithelial Lesions in People With HIV

OBJECTIVE

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

METHODS

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

RESULTS

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

CONCLUSION

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

To Improve Motivational Barriers to Retention in High Resolution Anoscopy, Patients and Providers Recommend Social and Environmental Changes: A Sequential Explanatory Mixed-Methods Pilot Study in a Federally Qualified Health Center

Loss to follow-up (LTFU) in high-resolution anoscopy (HRA) programs jeopardizes the procedure's potential to help prevent anal cancer. We explored quality improvement factors to understand how to address this LTFU. Using the transtheoretical COM-B Model (Capability, Opportunity, Motivation, and Behavior) and a sequential explanatory mixed-methods design, we surveyed and interviewed 13 patients who remained engaged in HIV care but who delayed their HRA monitoring or treatment visits in the same community clinic, and 6 HRA clinicians and medical assistants. Analyses involved descriptive statistics and rapid qualitative analysis. Patients were racially, ethnically, and economically representative of the LTFU population, and were generally experienced with HRA (Mean HRA visits = 4.6, SD = 2.8, mdn = 3). Providers were experienced clinicians and medical assistants (Mean years providing HRA = 6.0, SD = 2.2). Analyses revealed two primary, related barriers: (A) motivational barriers such as physical pain, discomfort, embarrassment, and anxiety; which were largely borne from (B) opportunity barriers such as difficulties with scheduling, inconsistent after-care (particularly for pain and discomfort), anxiety-inducing exam rooms and equipment, and internalized and anticipated stigma. Capability barriers, such as limited health literacy about HRA, were less common and, like motivational barriers, linked to opportunity barriers. Participants recommended potential facilitators, including easier scheduling, standardization of pain management and after-care services, and examination room modifications to reduce anxiety. To retain HRA patients in community settings, interventions should address social and physical opportunity barriers that strongly determine motivational and capability barriers. Improving convenience, standardizing pain management, and introducing stigma interventions specific to HRA, could alleviate both motivational and capability barriers.

Engagement and factors associated with annual anal human papillomavirus screening among sexual and gender minority individuals

Objectives

Annual screening with a provider has been recommended for groups at highest risk for anal cancer. Anal self-sampling could help address screening barriers, yet no studies have examined annual engagement with this method.

Methods

The Prevent Anal Cancer Self-Swab Study recruited sexual and gender minority individuals 25 years and over who have sex with men in Milwaukee, Wisconsin to participate in an anal cancer screening study. Participants were randomized to a home or clinic arm. Home-based participants were mailed an anal human papillomavirus self-sampling kit at baseline and 12 months, while clinic-based participants were asked to schedule and attend one of five participating clinics at baseline and 12 months. Using Poisson regression, we conducted an intention-to-treat analysis of 240 randomized participants who were invited to screen at both timepoints.

Results

58.8% of participants completed annual (median=370 days) anal screening. When stratified by HIV status, persons living with HIV had a higher proportion of home (71.1%) versus clinic (22.2%) annual screening ( p <0.001). Non-Hispanic Black participants had a higher proportion of home-based annual anal screening engagement (73.1%) compared to annual clinic screening engagement (31.6%) ( p =0.01). Overall, annual screening engagement was significantly higher among participants who had heard of anal cancer from an LGBTQ organization, reported "some" prior anal cancer knowledge, preferred an insertive anal sex position, and reported a prior cancer diagnosis. Annual screening engagement was significantly lower for participants reporting a medical condition.

Conclusions

Annual screening engagement among those at disproportionate anal cancer risk was higher in the home arm.

The influence of home versus clinic anal human papillomavirus sampling on high-resolution anoscopy uptake in the Prevent Anal Cancer Self-Swab Study

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.

Knowledge and Perceived Emotions Regarding an Anal Cancer Preventive Program in People Diagnosed With HIV: A Qualitative Study

BACKGROUND

To the best of our knowledge, no studies have yet examined the emotional repercussions of the care processes among people infected with the human immunodeficiency virus who participate in preventive anal cancer screening programs.

OBJECTIVE

This study aimed to explore the knowledge, emotions, sexuality, barriers, and facilitators perceived by this patient group during the process of anal cancer screening and diagnosis.

METHODS

Detailed, semistructured, qualitative interviews were completed with 17 men and 3 women to explore their knowledge, experiences, and emotions regarding the screening process. Purposive sampling was conducted on the basis of age, gender, and type of lesion diagnosed in the anal biopsy.

RESULTS

Four major themes were identified: 1) knowledge of the disease and its treatment, 2) emotions perceived by the patients, 3) the influence of screening on sexual practices, and 4) facilitators and obstacles during the care provision process. Patients reported appropriate knowledge of anal cancer and human papillomavirus. Predominant emotions were worry and fear with avoidance as one of the coping strategies.

CONCLUSION

These results suggest that communication of information and clinical results can be improved.

IMPLICATION FOR PRACTICE

Understanding the facilitators and barriers to the program will allow the integration of interventions designed to improve healthcare provision into direct care.

The influence of home versus clinic anal human papillomavirus sampling on high-resolution anoscopy uptake in the Prevent Anal Cancer Self-Swab Study

Background

Anal cancer disproportionately affects men who have sex with men (MSM) 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.

Method

MSM and trans persons 25 years and older were randomized to home-based self-sampling or clinical sampling. All were asked to attend in-clinic HRA one year later. We regressed HRA attendance on study arm using multivariable Poisson regression and assessed HRA acceptability using χ 2 tests.

Results

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 1.44, 95% CI 1.11 - 1.87) and lower among participants preferring 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); however, 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.

Impact of a High-Resolution Anoscopy Clinic on Management of Anal Dysplasia in Women Living With HIV

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.

Barriers and facilitators to anal cancer screening among people living with HIV in Puerto Rico

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.

Facilitators and Barriers to HPV Self-Sampling as a Cervical Cancer Screening Option among Women Living with HIV in Rural Uganda

Background: There is a paucity of studies exploring women living with HIV's (WLWH) experiences relating to human papillomavirus (HPV) self-sampling as cervical cancer (CC) screening approach, either at the clinic or at the home setting, using qualitative methods. Our study explored facilitators and barriers to HPV self-sampling as a CC screening approach among human immunodeficiency virus (HIV)-infected women, as supported by the new WHO guidelines of using the HPV test as a screening modality. Methods: The study was guided by the health promotion model (HPM), which helps individuals achieve higher levels of well-being. The phenomenology design was used to explore the deeper facilitators and barriers of women regarding self-sampling, either at home or in clinical settings, at Luweero District Hospital, Uganda. The in-depth interview (IDI) guide was translated from English to Luganda. Qualitative data analysis was guided by content analysis techniques. The transcripts were coded in NVivo 20.7.0. The coded text was used to generate categories of analytically meaningful data that guided the formation of themes, the interpretation of results, and the final write-up. Results: WLWH were motivated to screen for HPV using the clinic-based approach because of perceived early diagnosis and treatment, visualization of the cervix, and free service, while reduced distance, privacy and the smooth sample collection kit were motivators for the home-based approach. A barrier that cut across the two HPV self-sampling approaches was a lack of knowledge about HPV. The barriers to clinic-based HPV self-sampling screening included lack of privacy, perceived painful procedures for visual inception under acetic acid (VIA), and fear of finding the disease. Stigma and discrimination were reported as the major barriers to the home-based HPV self-sampling approach. The major reasons why some WLWH refused to screen were fear of finding the disease, stress, and financial disruptions related to being diagnosed with CC disease. Conclusions: Therefore, early diagnosis for HPV and CC enhances clinic-based HPV self-sampling, while privacy enhances the home-based HPV self-sampling approach. However, fear of finding a disease and the lack of knowledge of HPV and CC hinders HPV self-sampling. Finally, designing pre- and post-testing counselling programs in HIV care is likely to increase the demand for HPV self-sampling.

A Novel Medical Student Elective Course in Lesbian, Gay, Bisexual, Transgender, Queer, Intersex, Asexual, and Sexually and Gender Diverse Health: Training Tomorrow's Physician-Leaders

Purpose: Inadequate medical training in lesbian, gay, bisexual, transgender, queer, intersex, asexual, and sexually and gender diverse (LGBTQIA+) health care contributes to health disparities. This article reports on a novel 4-week elective course at Harvard Medical School that prepares students to become physician-leaders in LGBTQIA+ health care. Methods: The course engages students in multidisciplinary clinical placements, self-directed learning, and mentored scholarly projects, all specifically relevant to LGBTQIA+ health. The authors qualitatively reviewed student experiences, and quantitatively analyzed course evaluations. Results: Between 2016 and 2022, 30 students completed the course, and 12 scholarly projects resulted in a published peer-reviewed article authored by the student. Students who completed evaluations rated the course as excellent and reported increased interest and core knowledge in LGBTQIA+ health care. Conclusion: This novel program has demonstrated feasibility and may serve as a model for establishing other advanced medical student clinical and scholarly electives on LGBTQIA+ health care.

Participation, barriers, and facilitators of cancer screening among LGBTQ+ populations: A review of the literature

The LGBTQ+ community is at higher risk of certain cancers but is less likely to participate in screening programs or engage with preventive healthcare. Despite this, the barriers and facilitators to cancer screening are not well understood in this population. We conducted a literature review of research related to LGBTQ+ participation in cancer screening, as well as barriers and facilitators to participation. Following abstract and full-text screening, 50 studies were included in the final synthesis. Compared to their heterosexual counterparts, lesbian and bisexual women were less likely to participate in cervical cancer screening and mammography, but gay and bisexual men were more likely to participate in anal and colorectal cancer screening. Transgender individuals had lower rates of screening than cisgender individuals for all cancer types. Barriers to participation were found at the individual-, provider-, and administrator-level, and good communication with a healthcare provider was the strongest facilitator. These results provide reasonable first steps toward improving participation rates for LGBTQ+ populations in cancer screening. Patient-centered approaches should draw on core guiding principles to inform the provision of care, including anticipating LGBTQ+ patients, improving knowledge about care for these patients, and confronting individually-held biases that may affect care, in order to improve care experiences and participation rates in preventive services.

Gay and Bisexual Men Who Report Anal Sex Stigma Alongside Discomfort Discussing Anal Sex with Health Workers Are Less Likely to Have Ever Received an Anal Examination or Anal Swab

Purpose: We sought to determine whether stigma toward anal sexuality was associated with having ever received an anal examination or anal swab among gay and bisexual men (GBM). Methods: In 2017, we conducted a cross-sectional online survey with 1513 adult cisgender GBM living in the United States. We used structural equation modeling to test whether the Anal Sex Stigma Scales (a validated measure comprising provider stigma, self-stigma, and silence) was negatively associated with lifetime receipt of anorectal examination or anal swabbing by a medical provider. The model assessed mediation by respondents' comfort discussing anal sex practices with health workers and adjusted for possible confounders. Results: As hypothesized, anal sex stigma was associated with less comfort discussing anal sex (β = -0.44, 95% confidence interval [CI]: -0.50 to -0.38, p < 0.001), and greater comfort was associated with greater likelihood of screening (β = 0.28, 95% CI: 0.19 to 0.37, p < 0.001). The model demonstrated good fit (root mean square error of approximation = 0.045, comparative fit index, and Tucker-Lewis index each = 0.99) and adjusted for everyday discrimination, social support specific to anal sex, age, income, education, medical coverage, outness, and ethnic/racial identification. Collectively, model variables accounted for 48% of the variance in screening (p < 0.001). Conclusion: GBM who endorsed less anal sex stigma reported greater comfort discussing anal sex with health workers and were more likely to have ever received anal health screening by a medical provider. To improve anal health and cancer prevention among GBM, anal sex stigma and related discomfort discussing anal sex with health workers are targets for intervention.

The other side of screening: predictors of treatment and follow-up for anal precancers in a large health system

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.

"That's Only for Women": The Importance of Educating HIV-Positive Sexual Minority Men on HPV and High Resolution Anoscopy (HRA)

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.

Anal cancer screening in a high-risk behavior group: A local picture

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.
