Abstract
OBJECTIVE To assess the oncogenic human papillomavirus (HPV) determination and the cotesting HPV and anal cytology value to detect high-grade anal intraepithelial neoplasia (HGAIN) in a cohort of HIV-MSM. DESIGN AND METHODS Prospective study of HIV-infected MSM who underwent screening for anal dysplasia. Screening program includes anal cytology, HPV testing, and high-resolution anoscopy (HRA) at each visit. Histological samples were obtained if suspicious lesions were revealed by HRA. Sensitivity and specificity of the different tests were calculated by using histological results of HRA-guided biopsy as the reference test for HGAIN diagnosis. RESULTS From May 2009 to August 2016, 692 HIV-infected MSM underwent 1827 anal cytologies, 1841 HRA examinations, and 1607 HPV testing. At first screening visit, anal cytology results were abnormal in 418 (60.4%) of 692 patients, and oncogenic HPV genotypes were found in 482 (79.5%) of 606 patients. Anal cytology showed a sensitivity of 89.2% [95% confidence interval (CI); 80.7-94.2] and a specificity of 44.2% (95% CI; 40.2-48.2) to detect HGAIN. Oncogenic HPV testing had 90.4% sensitivity (95% CI; 82-86.8) and 24.4% specificity (95% CI; 20.8-28.3). Cotesting showed a 97.4% sensitivity (95% CI; 91-99.3) and 14% specificity (95% CI; 11.2-17.3). In patients with atypical squamous cells of uncertain significance on cytology, oncogenic HPV testing had 91.3% sensitivity and 28.3% specificity to detect HGAIN. CONCLUSION Abnormal cytology and oncogenic HPV determination showed similar sensitivity for detecting HGAIN. The two tests used together improved the sensitivity but with lowered specificity. In our opinion, HPV testing does not improve HGAIN detection and should not replace anal cytology as a standard screening test for HIV-infected MSM.

Abstract
BACKGROUND Longitudinal studies of histological outcomes after anal cytological screening in men who have sex with men (MSM) are rare. This study measured the positive predictive values (PPVs) of each level of baseline cytological abnormality in MSM in Sydney, Australia, over a 12-month period. METHODS The Study of the Prevention of Anal Cancer is a 3-year prospective study of the natural history of anal human papillomavirus infection in MSM at least 35 years old. For each participant with a baseline cytological abnormality, the worst histology was recorded at the baseline high-resolution anoscopy and at 6 and 12 months. PPVs for a histological high-grade squamous intraepithelial lesion (HSIL) diagnosis were calculated for each level of baseline cytological abnormality at each time point. RESULTS Among 424 men who completed 3 visits, the PPV of a cytological HSIL increased from 71.6% at the baseline to 86.4% at 6 months and to 92.6% at 12 months (P < .001). For cytological atypical squamous cells, cannot rule out high-grade squamous intraepithelial lesion (ASC-H), the PPV increased from 51.5% at the baseline to 69.7% at 6 months and to 75.8% at 12 months (P = .004). At each time point, the PPV of a cytological HSIL was significantly higher than the PPV of ASC-H. The PPV of low-grade cytology reports was significantly lower than the PPV of ASC-H at each time point. CONCLUSIONS In a cohort of MSM, a baseline histological HSIL diagnosis after an HSIL cytoprediction is high, and it increases with further examinations over the course of 12 months. Lower levels of cytological abnormalities have significantly lower PPVs. These data can inform patient management and the quality assessment of each aspect of the screening pathway.

Abstract
Squamous cell carcinoma of anus (SCCA) is one of the most frequent non-AIDS-defining diseases in HIV patients, mainly in men who have sex with men (MSM), and it is associated with human papillomavirus (HPV) infection.To determine the prevalence of high-risk HPV (HR-HPV) genotypes, premalignant lesions (HSIL) and SCCA in a cohort of HIV-positive MSM; to study the distribution of HPV genotypes according to anal histology results; and to analyze risk factors for this infection.This prospective single-center study was conducted between May 2010 and September 2016. At the study visit, cotton swabs were used to collect anal samples for cytology study in ThinPrep Pap Test liquid medium (Thin Prep Processor 2000, Hologic Corp, USA), and for HPV PCR (Linear Array HPV Genotyping Test). After, high-resolution anoscopy (HRA) (Zeiss 150 fc) was carried out. Logistic regression analysis was performed to identify risk factors for HR-HPV infection.The study included 319 patients, with mean age of 36.7 years; HR-HPV was detected in 81.3%. The prevalence of HSIL was 13.5% and SCCA was 0.3%. With regard to the distribution of HPV genotypes according to histology results, HPV 16 was the most frequent genotype in normal anal mucosa (26.7%), in LSILs (36.9%), and in HSILs (38%). In multivariate analysis, CD4 nadir < 200 cells/μL was the factor associated with infection by HR-HPV (OR 3.66, 95% CI 1.05%-12.75%).HIV-positive MSM showed a high prevalence of HSIL+ lesions and of infection by oncogenic HPV, which appears to be favored by a deficient immune system. HPV 16 was the most frequently isolated genotype in anal mucosa, regardless of lesion type.

Abstract
We studied DNA methylation patterns of human papillomavirus (HPV) and tumor suppressor gene EPB41L3 in 148 anal and perianal biopsies to determine whether high levels of methylation would be associated with anal intraepithelial neoplasia (AIN). The most prevalent HPV type was HPV16, detected in 54% of the 30 benign biopsies, 33% of the 43 low-grade AIN (lgAIN), 82% of the 59 high grade AIN (hgAIN) and 4 of the 5 anal cancers. A methylation score was developed (0.561*HPV16me+0.439*EPB41L3) which had increasing values with severity of disease: the mean was 8.1% in benign, 13.2% in lgAIN, 22.3% in hgAIN and 49.3% in cancers (p < 0.0001). The methylation score as a triage classifier at a cut-off of 8.8 gave a sensitivity of 90.6% (95% CI: 82.8, 96.9), specificity of 50.7% (95% CI: 39.7, 61.6) and area under the curve of 0.82 (95% CI: 0.75-0.89) for separating hgAIN and cancer from benign and lgAIN biopsies. We conclude that methylation of HPV16 and EPB41L3 show highly significant association with increasing severity of AIN and cancer and may be useful as biomarkers in anal disease.

Abstract
PURPOSE This study aimed to characterize the sociodemographic characteristics of sexual minority (i.e., gay, lesbian, bisexual) adults and compare sexual minority and heterosexual populations on nine Healthy People 2020 leading health indicators (LHIs). METHODS Using a nationally representative, cross-sectional survey (National Health Interview Survey 2013-2015) of the civilian, noninstitutionalized population (228,893,944 adults), nine Healthy People 2020 LHIs addressing health behaviors and access to care, stratified using a composite variable of sex (female, male) and sexual orientation (gay or lesbian, bisexual, heterosexual), were analyzed individually and in aggregate. RESULTS In 2013-2015, sexual minority adults represented 2.4% of the U.S. POPULATION Compared to heterosexuals, sexual minorities were more likely to be younger and to have never married. Gays and lesbians were more likely to have earned a graduate degree. Gay males were more likely to have a usual primary care provider, but gay/lesbian females were less likely than heterosexuals to have a usual primary care provider and health insurance. Gay males received more colorectal cancer screening than heterosexual males. Gay males, gay/lesbian females, and bisexual females were more likely to be current smokers than their sex-matched, heterosexual counterparts. Binge drinking was more common in bisexuals compared to heterosexuals. Sexual minority females were more likely to be obese than heterosexual females; the converse was true for gay males. Sexual minorities underwent more HIV testing than their heterosexual peers, but bisexual males were less likely than gay males to be tested. Gay males were more likely to meet all eligible LHIs than heterosexual males. Overall, more sexual minority adults met all eligible LHIs compared to heterosexual adults. Similar results were found regardless of HIV testing LHI inclusion. CONCLUSION Differences between sexual minorities and heterosexuals suggest the need for targeted health assessments and public health interventions aimed at reducing specific negative health behaviors.

[PMID: 28720147 PMCID: PMC5516305 DOI: 10.1186/s12981-017-0160-0] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/02/2017] [Accepted: 07/11/2017] [Indexed: 01/05/2023] Open
Abstract
Background Safety and immunogenicity of the quadrivalent human papillomavirus (qHPV) vaccine were evaluated in HIV-positive Spanish MSM. The prevalence of High Squamous Intraepithelial Lesions (HSIL) and genotypes of high-risk human papillomavirus (HR-HPV) were also determined, as well as risk factors associated with the presence of HR-HPV in anal mucosa. Methods This is a randomised, double blind, placebo-controlled trial of the quadrivalent HPV (qHPV) vaccine. The study enrolled from May 2012 to May 2014. Vaccine and placebo were administered at 0, 2 and 6 months (V1, V2, V3 clinical visits). Vaccine antibody titres were evaluated at 7 months. Cytology (Thin Prep® Pap Test), HPV PCR genotyping (Linear Array HPV Genotyping Test), and high-resolution anoscopy (Zeiss 150 fc© colposcope) were performed at V1. Results Patients (n = 162; mean age 37.9 years) were screened for inclusion; 14.2% had HSIL, 73.1% HR-HPV and 4.5% simultaneous infection with HPV16 and 18. Study participants (n = 129) were randomized to qHPV vaccine or placebo. The most common adverse event was injection-site pain predominating in the placebo group [the first dose (83.6% vs. 56.1%; p = 0.0001]; the second dose (87.8% vs. 98.4%; p = 0.0001); the third dose (67.7% vs. 91.9%; p = 0.0001). The vaccine did not influence either the viral load of HIV or the levels of CD4. Of those vaccinated, 76% had antibodies to HPV vs. 30.2% of those receiving placebo (p = 0.0001). In the multivariate analysis, Older age was associated with lower HR-HPV infection (RR 0.97; 95% CI 0.96–0.99), and risk factor were viral load of HIV >200 copies/µL (RR 1.42 95% CI 1.17–1.73) and early commencement of sexual activity (RR 1.35; 95% CI 1.001–1.811). Conclusions This trial showed significantly higher anti-HR-HPV antibody titres in vaccinated individuals than in unvaccinated controls. There were no serious adverse events attributable to the vaccine. In our cohort, 1 of every 7 patients had HSIL and the prevalence of combined infection by genotypes 16 and 18 was low. This suggests that patients could benefit from receiving qHPV vaccine. Older age was the main protective factor against HR-HPV infection, and non-suppressed HIV viremia was a risk factor.

Abstract
BACKGROUND The present study investigated human papillomavirus (HPV) prevalence in anal and urine samples, and evaluated cytological findings among human immunodeficiency virus (HIV)-infected Japanese men who have sex with men (MSM). METHODS A total of 148 patients were enrolled. Anal and urine samples were collected from each participant, and a HPV-DNA test and genotyping were performed using flow-through hybridization. In addition, anal cytology was evaluated based on Papanicolaou staining. Questionnaires regarding lifestyle habits and sexual behavior were obtained. RESULTS The β-globin gene was positive in 131 (88.5%) anal samples and 139 (94.0%) urine samples. Among the β-globin-positive samples, the HPV prevalence in anal and urine samples was 80.9% and 30.9%, respectively. High-risk HPV (HR-HPV) was detected in 57.3% of anal samples and 20.9% of urine samples. Among 122 adequate cytological samples, anal cytological abnormalities were observed in 99 cases (81.1%). Anal cytological tests revealed that atypical squamous cells of an undetermined significance (ASCUS) were detected in 57 (46.7%) patients, followed by low-grade squamous intraepithelial lesions (SIL) in 35 (28.7%), high-grade SIL in five (4.1%), and atypical squamous cells cannot exclude high-grade SIL (ASC-H) in two (1.6%), respectively. The nadir counts of CD4-positive T-lymphocyte less than 200 μL and anal HR-HPV infection were independent risk factors for anal cytological atypia over ASC-H. CONCLUSIONS The present study demonstrated high HPV prevalence in the anus and urine, and showed a high incidence of anal cytological atypia associated with HR-HPV infections among HIV-infected MSM patients.

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
There is a complex interrelationship between human papillomaviruses (HPV) and human immunodeficiency viruses (HIV) that has been recognized from the start of the HIV epidemic. Cervical cancer was used as a surveillance indicator for acquired immunodeficiency syndrome (AIDS) before definitive identification of the viral etiology of either condition were known. Careful epidemiologic studies combined with clinical and laboratory measures of HPV, HPV-associated disease, and HIV have helped us understand many aspects of the relationship between these two virus groups; however, questions remain. The histopathology associated with HPV is identical in HIV-positive and negative patients though the lesions are more frequent, with higher frequency of multiple HPV types, and persistent in HIV infected individuals. In this review we will briefly explain the pathobiology of HPV in HIV-infected persons and the potential impact of secondary (screening) and primary (vaccination) prevention to reduce HPV-associated disease in those infected with HIV.

Abstract
Human papillomavirus (HPV) infection is mostly asymptomatic, but may also have many diverse clinical signs encompassing benign ano-genital lesions, and carcinomas. Recently, interest has also particularly focused on anal cancer since, over the last decades, its incidence has been greatly increasing in developed countries, both in women and men and is drastically higher in specific risk groups, such as men who have sex with men (MSM) and HIV-1 infected individuals. Approximately 88% of anal cancer cases worldwide are associated with HPV infection. This review summarizes our current understanding of anal HPV infection, discussing its epidemiology and risk factors in various populations, and the state of the art in the detection of anal HPV infection and its related lesions through both cytology and histology. Finally, we discuss the clinical management and therapy for these lesions.

Abstract
Lesbian, gay, bisexual, transgender (LGBT), and questioning youth represent a diverse population who are affected by many sexual health inequities, including increased risk for human immunodeficiency virus (HIV) and sexually transmitted infections (STIs). To provide comprehensive sexual health care for LGBT youth, providers should set the stage with a nonjudgmental, respectful tone. Providers should be competent in recognizing symptoms of STIs and HIV and aware of the most up-to-date screening guidelines for LGBT youth. Sexual health visits should also focus on prevention, including safer sex practices, HIV pre-exposure and post-exposure prophylaxis, family planning, and immunization for hepatitis and human papillomavirus.

Abstract
PURPOSE Limited data are available on anal squamous intraepithelial lesions (ASILs) and anal human papillomavirus (HPV) infection in young, Black populations. The purpose of this study was to examine the prevalence of and relationships between ASILs and high-risk HPV infection in a young (<30 years of age), predominantly Black, men who have sex with men (MSM) population. METHODS Results of anal cytology and HPV DNA were gathered for 83 individuals. RESULTS Forty-two percent of individuals (35) had atypical squamous cells of undetermined significance and 33% (27) had low-grade squamous intraepithelial lesion by cytology. Only 9% tested positive for both high-risk HPV subtypes 16 and 18. CONCLUSION Low rates of infection with both HPV types 16 and 18 may provide further evidence that we should continue to vaccinate young, Black MSM against HPV.

Abstract
BACKGROUND High-grade intraepithelial neoplasia is known to progress to invasive squamous-cell carcinoma of the anus. There are limited reports on the rate of progression from high-grade intraepithelial neoplasia to anal cancer in HIV-positive men who have sex with men. OBJECTIVES The purpose of this study was to describe in HIV-positive men who have sex with men with perianal high-grade intraepithelial neoplasia the rate of progression to anal cancer and the factors associated with that progression. DESIGN This was a prospective cohort study. SETTINGS The study was conducted at an outpatient clinic at a tertiary care center in Toronto. PATIENTS Thirty-eight patients with perianal high-grade anal intraepithelial neoplasia were identified among 550 HIV-positive men who have sex with men. INTERVENTION All of the patients had high-resolution anoscopy for symptoms, screening, or surveillance with follow-up monitoring/treatment. MAIN OUTCOME MEASURES We measured the incidence of anal cancer per 100 person-years of follow-up. RESULTS Seven (of 38) patients (18.4%) with perianal high-grade intraepithelial neoplasia developed anal cancer. The rate of progression was 6.9 (95% CI, 2.8-14.2) cases of anal cancer per 100 person-years of follow-up. A diagnosis of AIDS, previously treated anal cancer, and loss of integrity of the lesion were associated with progression. Anal bleeding was more than twice as common in patients who progressed to anal cancer. LIMITATIONS There was the potential for selection bias and patients were offered treatment, which may have affected incidence estimates. CONCLUSIONS HIV-positive men who have sex with men should be monitored for perianal high-grade intraepithelial neoplasia. Those with high-risk features for the development of anal cancer may need more aggressive therapy.

Abstract
To provide updates for the 2015 Centers for Disease Control and Prevention sexually transmitted diseases treatment guidelines on human papillomavirus (HPV) and anogenital warts (AGWs), a review of the literature was conducted in key topic areas: (1) epidemiology and burden of disease; (2) transmission and natural history; (3) diagnosis and management of AGWs; (4) occupational exposure of healthcare workers; (5) anal cancer screening among men who have sex with men (MSM); and (6) HPV vaccine recommendations. Most sexually active persons will have detectable HPV at least once in their lifetime; 14 million persons are infected annually, and 79 million persons have prevalent infection. HPV is transmitted frequently between partners; more frequent transmission has been reported from females to males than from males to females. A new formulation of imiquimod (3.75% cream) is recommended for AGW treatment. Appropriate infection control, including performing laser or electrocautery in ventilated rooms using standard precautions, is recommended to prevent possible transmission to healthcare workers who treat anogenital warts, oral warts, and anogenital intraepithelial neoplasias (eg, cervical intraepithelial neoplasia). Data are insufficient to recommend routine anal cancer screening with anal cytology in persons living with human immunodeficiency virus (HIV)/AIDS or HIV-negative MSM. An annual digital anorectal examination may be useful for early detection of anal cancer in these populations. HPV vaccine is recommended routinely for 11- or 12-year-olds, as well as for young men through age 21 years and young women through age 26 years who have not previously been vaccinated. HPV vaccine is also recommended for MSM, people living with HIV/AIDS, and immunocompromised persons through age 26 years.

Abstract
BACKGROUND In a cytology-based screening program intended to prevent anal cancer, the anal transformation zone (TZ) should be adequately sampled because it is the site most susceptible to the development of the cancer precursor, high-grade squamous intraepithelial lesion (HSIL). An adequate TZ component is defined as comprising at least 10 rectal columnar or squamous metaplastic cells. In the current study, the authors examined whether the presence of a TZ component in anal cytology correlated with the detection of histological HSIL. METHODS In a natural history study of anal human papillomavirus infection in homosexual men, all participants underwent liquid-based cytology and high-resolution anoscopy (HRA) with or without biopsy at each visit. True-negative cytology (negative cytology with non-HSIL biopsy or negative HRA), false-negative cytology (negative cytology with HSIL biopsy), and true-positive cytology (abnormal cytology with HSIL biopsy) were compared with regard to the presence or absence of a TZ component. RESULTS Of 617 participants, baseline results included 155 true-positive results, 191 true-negative results, and 31 false-negative results. The absence of an adequate TZ component was found to be significantly higher for false-negative (32.3%) than for either true-positive (11.0%; P = .0034) or true-negative (13.1%; P = .0089) results. CONCLUSIONS Significantly more false-negative cases lacked a TZ component compared with either true-positive or true-negative cases. TZ cells may be an important indicator of sample quality for anal cytology because, unlike cervical sampling, the anal canal is not visualized during cytology sampling.

Abstract
High-risk human papillomaviruses (HPVs) cause essentially all cervical cancers, most anal and oropharyngeal cancers, and some vaginal, vulvar, and penile cancers. Improved understanding of the pathogenesis of infection and the availability of newer tests are changing the approach to screening and diagnosis. Molecular tests to detect DNA from the most common high-risk HPVs are FDA approved for use in conjunction with cytology in cervical cancer screening programs. More-specific tests that detect RNA from high-risk HPV types are now also available. The use of molecular tests as the primary screening tests is being adopted in some areas. Genotyping to identify HPV16 and -18 has a recommended role in triaging patients for colposcopy who are high-risk HPV positive but have normal cytology. There are currently no recommended screening methods for anal, vulvar, vaginal, penile, or oropharyngeal HPV infections. HPV testing has limited utility in patients at high risk for anal cancer, but p16 immunohistochemistry is recommended to clarify lesions in tissue biopsy specimens that show moderate dysplasia or precancer mimics. HPV testing is recommended for oropharyngeal squamous cell tumors as a prognostic indicator. Ongoing research will help to improve the content of future guidelines for screening and diagnostic testing.

Abstract
BACKGROUND Studies regarding the performance of anal cytology in which both the screening test (cytology) and the diagnostic test (high-resolution anoscopy [HRA]) are performed in all members of a screening population are rare. The authors evaluated the performance of liquid-based anal cytology in a cohort of homosexual men in Sydney, New South Wales, Australia. METHODS The Study of the Prevention of Anal Cancer (SPANC) is a 3-year prospective study of the natural history of anal human papillomavirus infection in homosexual men aged ≥35 years. At baseline, all participants underwent a liquid-based anal cytology test and HRA at the same clinical visit. Biopsies were obtained for histological assessment if lesions suspicious for human papillomavirus infection were visible during HRA. Using any cytological abnormality as the threshold, the sensitivity, specificity, and positive and negative predictive values were calculated against histologically diagnosed high-grade squamous intraepithelial lesions (HSILs). RESULTS Among 617 men recruited, the median age was 49 years (range, 35-79 years) and 35.7% were positive for the human immunodeficiency virus. Overall, the sensitivity of cytology was 83.2%, the specificity was 52.6%, the positive predictive value was 45.8%, and the negative predictive value was 86.7%. Specificity improved with increasing age (P for trend =.041). Sensitivity was significantly higher in men with >1 anal octant of biopsy-confirmed HSIL (92.9% vs 77.7%; P = .010), and in those who had ≥10 metaplastic cells present on their cytology slides (87.5% vs 70.2%; P = .007). CONCLUSIONS Anal cytology was found to have a higher specificity in older men while maintaining sensitivity. Sensitivity was higher among those with more extensive HSILs and men with metaplastic cells present on cytology. Cancer Cytopathol 2016;124:415-24. © 2016 American Cancer Society.

Abstract
This review focuses on the early diagnosis of anal cancer and its precursor lesions through routine screening. A number of risk-stratification strategies as well as screening techniques have been suggested, and currently little consensus exists among national societies. Much of the current clinical rationale for the prevention of anal cancer derives from the similar tumor biology of cervical cancer and the successful use of routine screening to identify cervical cancer and its precursors early in the disease process. It is thought that such a strategy of identifying early anal intraepithelial neoplasia will reduce the incidence of invasive anal cancer. The low prevalence of anal cancer in the general population prevents the use of routine screening. However, routine screening of selected populations has been shown to be a more promising strategy. Potential screening modalities include digital anorectal exam, anal Papanicolaou testing, human papilloma virus co-testing, and high-resolution anoscopy. Additional research associating high-grade dysplasia treatment with anal cancer prevention as well as direct comparisons of screening regimens is necessary to develop further anal cancer screening recommendations.

Abstract
Anal cancer may be an emerging clinical problem in HIV-infected women particularly in resource-limited settings. Human papillomavirus (HPV) infection is a precursor to anal cancer and is prevalent in HIV-infected women, but the natural history of HPV infection and anal cancer precursors is not well described in this population. It is not known which specific dysplastic lesions in the anus are most likely to progress, and whether treatment of high grade squamous intraepithelial lesion reduces the incidence of anal cancer in women. Cervical HPV infection and associated lesions may be related to the pathogenesis and natural history of anal disease. Cervical screening is resource intensive but some limited infrastructure exists in most areas where cervical cancer is prevalent. Anal screening, however is not performed. It may be that the infrastructure for cervical screening may be leveraged in developing the appropriate research, screening and treatment tools for anal dysplasia.

[PMID: 26421104 PMCID: PMC4580949 DOI: 10.4253/wjge.v7.i13.1083] [Citation(s) in RCA: 22] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/26/2015] [Revised: 07/14/2015] [Accepted: 09/01/2015] [Indexed: 02/05/2023] Open
Abstract
High-resolution anoscopy (HRA) is a procedure where patients with an increased risk of anal cancer, like men who have sex with men, human immunodeficiency virus infected individuals, transplant patients and women with a history of lower genital tract neoplasia, with abnormal anal cytology results, are submitted to anal and perianal visualization under magnification. This will allow for a better detection of anal high-grade lesions that can be treated, in an effort to prevent anal cancer. Anal cancer screening follows the same principles that cervical cancer screening. During this procedure, an anoscope is inserted and a colposcope is used to examine systematically the squamocolumnar junction, the transformation zone and the perianal skin. Initially the observation is done with no staining and then with the application of acetic acid and Lugol's iodine solution, allowing for better lesion identification and characterization. Any suspicious lesion seen should be carefully evaluated and biopsied. Without HRA only a small percentage of suspicious lesions are identified. High-grade lesions that are detected can be ablated under HRA. This is a challenging exam to perform, with a long learning curve and the number of clinicians performing it is limited, although the growing number of patients that need to been screened. Specific equipment is required, with these patients ideally been followed by a multidisciplinary team, in a reference centre. HRA remains unfamiliar for many gastroenterologists.

Abstract
Objectives To evaluate the advantages of cytology and PCR of high-risk human papilloma virus (PCR HR-HPV) infection in biopsy-derived diagnosis of high-grade squamous intraepithelial lesions (HSIL = AIN2/AIN3) in HIV-positive men having sex with men (MSM). Methods This is a single-centered study conducted between May 2010 and May 2014 in patients (n = 201, mean age 37 years) recruited from our outpatient clinic. Samples of anal canal mucosa were taken into liquid medium for PCR HPV analysis and for cytology. Anoscopy was performed for histology evaluation. Results Anoscopy showed 33.8% were normal, 47.8% low-grade squamous intraepithelial lesions (LSIL), and 18.4% HSIL; 80.2% had HR-HPV. PCR of HR-HPV had greater sensitivity than did cytology (88.8% vs. 75.7%) in HSIL screening, with similar positive (PPV) and negative predictive value (NPV) of 20.3 vs. 22.9 and 89.7 vs. 88.1, respectively. Combining both tests increased the sensitivity and NPV of HSIL diagnosis to 100%. Correlation of cytology vs. histology was, generally, very low and PCR of HR-HPV vs. histology was non-existent (<0.2) or low (<0.4). Area under the receiver operating characteristics (AUROC) curve analysis of cytology and PCR HR-HPV for the diagnosis of HSIL was poor (<0.6). Multivariate regression analysis showed protective factors against HSIL were: viral suppression (OR: 0.312; 95%CI: 0.099-0.984), and/or syphilis infection (OR: 0.193; 95%CI: 0.045-0.827). HSIL risk was associated with HPV-68 genotype (OR: 20.1; 95%CI: 2.04-197.82). Conclusions When cytology and PCR HR-HPV findings are normal, the diagnosis of pre-malignant HSIL can be reliably ruled-out in HIV-positive patients. HPV suppression with treatment protects against the appearance of HSIL.

Abstract
BACKGROUND Homosexual men infected with human immunodeficiency virus (HIV) are at increased risk of developing anal cancer. The aim of this study was to assess the clinical sensitivity of anal cytology analysis and oncogenic human papillomavirus (HPV) detection for predicting histological anal intraepithelial neoplasia. METHODS Between March 2011 and December 2013, we enrolled 196 HIV-positive men in Taoyuan General Hospital, Taiwan. We analyzed the results of thin-preparation anal Pap smears, HPV genotyping, and histology of anoscopic biopsy samples. RESULTS The mean age (±standard deviation) was 31.43 (±8.74) years. The proportion (95 % confidence interval) with abnormal thin-preparation anal cytology was 36.2 % (29.8-43.2 %): 16.8 % (12.2-22.7 %) atypical squamous cells of undetermined significance, 14.8 % (10.5-20.4 %) low-grade squamous intraepithelial lesions, and 4.6 % (2.4-8.5 %) high-grade squamous intraepithelial lesions. At least one HPV genotype was detected in 90.8 % of subjects, and the mean number of HPV infection types was 4.41 (±3.24).The frequency of histological high-grade anal intraepithelial lesions was 7.14 % (95 % confidence interval 4.3-11.6 %). Anal cytology yielding atypical squamous cells of undetermined significance or higher grades resulted in a sensitivity of 64.3 %, specificity of 65.9 %, positive predictive value of 12.7 %, and negative predictive value of 96 %. Using both oncogenic HPV and cytology did not provide better performance. CONCLUSIONS Anal cytology yielding atypical squamous cells of undetermined significance or higher grades could detect two-thirds of high-grade anal intraepithelial neoplasias in HIV-infected men and should be promoted for anal cancer prevention.

Abstract
Worldwide, approximately 5 to 10% of the population is infected by a Human Papilloma Virus (HPV). Some of these viruses, with a high oncogenic risk (HPV HR), are responsible for about 5% of cancer. It is now accepted that almost all carcinomas of the cervix and the vulva are due to an HPV HR (HPV16 and 18) infection. However, these viruses are known to be involved in the carcinogenesis of many other cancers (head and neck [SCCHN], penis, anus). For head and neck cancer, HPV infection is considered as a good prognostic factor. The role of HPV HR in anal cancer is also extensively studied in high-risk patient's population. The role of HPV infection in the carcinogenesis of esophageal, bladder, lung, breast or skin cancers is still debated. Given the multiple possible locations of HPV HR infection, the question of optimizing the management of patients with a HPV+ cancer arises in the implementation of a comprehensive clinical and biological monitoring. It is the same in therapeutics with the existence of a preventive vaccination, for example.

Abstract
Background Although anal high-risk human papillomavirus (HR-HPV) infection and anal cytological abnormalities are highly prevalent among human immunodeficiency virus (HIV)-infected men who have sex with men (MSM), there are insufficient data on these abnormalities among HIV-infected heterosexual men (HSM) and women. In this study, we evaluated the prevalence of anal HR-HPV, cytological abnormalities, and performance of these screening tests in detecting high-grade anal intraepithelial neoplasia (AIN2+) among our cohort of HIV-infected MSM and non-MSM (HSM and women). Methods A single-center, retrospective cohort study was conducted with HIV-infected individuals who underwent anal cancer screening with anal cytology and HR-HPV testing from January 2011 to January 31, 2013. Results Screening of 221 HIV-infected individuals for both HR-HPV and anal cytology showed the presence of HR-HPV in 54% (abnormal anal cytology 48%) of MSM, 28% (abnormal anal cytology 28%) of HSM, and 27% (abnormal anal cytology 34%) of women. Among 117 (53%) individuals with abnormal results (HR-HPV-positive and/or cytology was atypical squamous cells of undetermined significance or above), 67 underwent high resolution anoscopy. Of these 67 individuals, 22 individuals had AIN2+ (17 MSM, four women, and one HSM). HR-HPV correlated better with AIN2+ than with anal cytology on biopsy in both MSM (r=0.29 versus r=0.10; P=0.05 versus P=0.49) and non-MSM (r=0.36 versus r=−0.34; P=0.08 versus P=0.09). Conclusion Given the presence of AIN2+ in screened HIV-infected HSM and women, routine anal cancer screening in all HIV-infected individuals should be considered. HR-HPV merits further evaluation for anal cancer screening among non-MSM.

Abstract
Neoplasia is the second most common cause of mortality in HIV patients. The prevalence of anal cancer among men who have sex with men (MSM) has continued to increase since the introduction of antiretroviral therapy. We screened 94 HIV-infected MSM patients. We found high-grade squamous intraepithelial lesions (HSIL) in six of the patients. The calculated prevalence of HSIL was 6.4% (95% confidence interval: 2.9-13.2). The study and implementation of screening programs for high-risk groups is a priority.

Abstract
Homosexuality is a global human phenomenon. Although the American Psychiatric Association removed homosexuality from its list of disorders more than 35years ago, homophobia among physicians is still widely prevalent. Men who have sex with men (MSM) form a relatively new epidemiological risk group for STI. To perform correct management, clinicians evaluating men with male-male sex contacts for STI related complaints or STI screening must obtain a thorough sexual history. Emerging STI like lymphogranuloma venereum, hepatitis C, and multidrug resistant N. gonorrhea strains have been described first in MSM. STI related proctitis often occur in MSM. Within the MSM population, HIV positive patients form a special group affected by STI related diseases, such as anal carcinoma and neurosyphilis. The final part of this review concludes with recommendations to reduce the STI burden in MSM.

Abstract
HIV-infected individuals are 28 times more likely than the general population to be diagnosed with anal cancer. An integrative review of recommendations and guidelines for anal cancer screening was performed to provide a succinct guide to inform healthcare clinicians. The review excluded studies that were of non-HIV populations, redundant articles or publications, non-English manuscripts, or nonclinical trials. The review found no formal national or international guidelines exist for routine screening of anal cancer for HIV-infected individuals. To date, no randomized control trial provides strong evidence supporting efficaciousness and effectiveness of an anal cancer screening program. The screening recommendations from seven international-, national-, and state-based reports were reviewed and synthesized in this review. These guidelines suggest anal cancer screening, albeit unproven, may be beneficial at decreasing the incidence of anal cancer. This review highlights the paucity of screening-related research and is an area of need to provide clear direction and to define standard of care for anal cancer screening in HIV-infected persons.

Abstract
Anal squamous cell carcinoma is rare in the general population but certain populations, such as persons with HIV, are at increased risk. High-risk populations can be screened for anal cancer using strategies similar to those used for cervical cancer. However, little is known about the use of such screening practices across jurisdictions. Data were collected using an online survey. Health care professionals currently providing anal cancer screening services were invited to complete the survey via email and/or fax. Information was collected on populations screened, services and treatments offered, and personnel. Over 300 invitations were sent; 82 providers from 80 clinics around the world completed the survey. Fourteen clinics have each examined more than 1000 patients. Over a third of clinics do not restrict access to screening; in the rest, eligibility is most commonly based on HIV status and abnormal anal cytology results. Fifty-three percent of clinics require abnormal anal cytology prior to performing high-resolution anoscopy (HRA) in asymptomatic patients. Almost all clinics offer both anal cytology and HRA. Internal high-grade anal intraepithelial neoplasia (AIN) is most often treated with infrared coagulation (61%), whereas external high-grade AIN is most commonly treated with imiquimod (49%). Most procedures are performed by physicians, followed by nurse practitioners. Our study is the first description of global anal cancer screening practices. Our findings may be used to inform practice and health policy in jurisdictions considering anal cancer screening.

Abstract
INTRODUCTION High-risk (HR) human papillomavirus (HPV) testing is accepted as the standard of care for surveillance of cervical cancer. Its role in anal cancer is not clear. This study was therefore designed to determine if HR HPV genotyping is a useful adjunct in management of abnormal anal Papanicolaou (Pap) tests. MATERIALS AND METHODS HR HPV genotyping and virus quantification was performed on 101 residual anal Pap test samples (28 negative, 25 atypical squamous cells of undetermined significance [ASC], 34 low-grade squamous intraepithelial lesion [LSIL], 6 atypical squamous cells of undetermined significance, cannot exclude high-grade squamous intraepithelial lesion, and 8 high-grade squamous intraepithelial lesion) using multiplex real-time polymerase chain reaction. Results were correlated with cytodiagnosis and follow-up. RESULTS HR HPV was detected in 82% (50% negative, 84% ASC, and 100% LSIL and above) cases. Multiple genotypes were present in 71% of cases. Genotype number and viral load correlated with the degree of anal cytologic abnormality. HPV 16, 18, and 45 were the most frequent genotypes detected. The high frequency of HR HPV in abnormal anal cytologies limits its use as an adjunct test. Anal Pap test samples with anal intraepithelial neoplasia 2/3 (AIN 2/3) on follow-up were positive for HPV 16 and/or 18 (HPV 16/18+) in 80% of cases. We hypothesize that testing for HPV 16/18 on the ASC and LSIL cases would have detected AIN 2/3 with a sensitivity of 81%, specificity of 43%, positive predictive value of 39%, and negative predictive value of 83%. CONCLUSIONS Our results with a small cohort suggest that genotyping for HPV 16/18 may be effective in identifying patients at high risk for anal cancer and in reducing the number of anoscopy referrals. Prospective studies with follow-up are warranted.

Abstract
BACKGROUND The incidence of anal cancer among HIV-infected patients is higher than that in other populations. Anal high-grade squamous intraepithelial lesions are considered precursors to invasive squamous-cell carcinomas and are strongly associated to high-risk human papillomavirus infection. OBJECTIVE The aim of this study is to determine the prevalence of anal high-grade squamous intraepithelial lesions through screening based on cytology and high-resolution anoscopy with biopsy in a cohort of HIV-infected men who have sex with men. DESIGN This investigation is an observational cross-sectional cohort study. SETTING The study was conducted in the HIV unit of a tertiary hospital in Spain. PATIENTS Three hundred HIV-infected men who have sex with men participated. Physical examination led to a diagnosis of perianal squamous-cell carcinoma and high-grade squamous intraepithelial lesions in 2 patients who were then excluded. INTERVENTIONS Anal liquid cytology was performed. Patients with cytological abnormalities underwent high-resolution anoscopy and biopsy. MAIN OUTCOME MEASURE The primary outcome measured was biopsy-proven high-grade squamous intraepithelial lesions. RESULTS The median age was 41 ± 10.5 years. The mean and nadir CD4 cell counts were 651 ± 205 cells/mm(3) (interquartile range, 438-800) and 273 ± 205 cells/mm(3) (interquartile range, 131-362). High-risk human papillomavirus was detected in 80.9% of patients, and human papillomavirus 16 was detected in 35.9% of patients. The mean number of human papillomavirus genotypes was 4.6 ± 2.9 (CI, 2-6). Anal cytology was abnormal in 40.9% of patients (n = 122/298; interquartile range, 35.4%-46.6%). High-resolution anoscopy and biopsies were performed in 119 patients. The results of histological analyses were as follows: normal, 7.7% (n = 23); condyloma, 4.3% (n = 13); anal intraepithelial neoplasia 1, 5.7% (n = 17); anal intraepithelial neoplasia 2, 14% (n = 42); and anal intraepithelial neoplasia 3, 8% (n = 24). The overall prevalence of high-grade squamous intraepithelial lesions among patients with abnormal cytology was 54% (95% CI, 45.1%-62.8%). A diagnosis of high-grade squamous intraepithelial lesions was associated with human papillomavirus 16 and human papillomavirus 51 infection, and with detection of a higher number of human papillomavirus genotypes. LIMITATIONS High-resolution anoscopy was only performed in patients with abnormal cytology. CONCLUSIONS The prevalence of high-risk human papillomavirus infection and high-grade squamous intraepithelial lesions is high in our cohort. Physical examination enabled straightforward diagnosis of perianal high-grade squamous intraepithelial lesions and squamous-cell carcinoma in 2 patients.

Abstract
BACKGROUND High-grade anal intraepithelial neoplasia (AIN) is present in many human immunodeficiency virus (HIV)-positive men who have sex with men. The major etiologic factor is infection with an oncogenic human papillomavirus (HPV) genotype. We investigated whether individual components of high-grade AIN are caused by single HPV types. METHODS DNA was isolated from whole-tissue sections of 31 high-grade AIN that were recovered from 21 HIV-positive men who have sex with men. The SPF10 PCR/LiPA25 HPV genotyping system was used for DNA analysis. In whole-tissue sections with multiple HPV types, polymerase chain reaction was repeated in regions of AIN sampled by laser-capture microdissection. The results were compared with HPV types in anal swabs. RESULTS A single HPV type was observed in 15 (48%) of 31 whole-tissue sections. In an additional 14 whole-tissue sections, 1 HPV type was found in each lesion sample evaluated by laser-capture microdissection. Consequently, in 29 of 31 biopsy specimens (94%), a single HPV type was found in each lesional component studied. Two whole-tissue sections contained collision regions, each with 2 HPV types. HPV16 was presumed to be causative in 14 of 31 biopsy specimens (45%). More than half of the anal swabs did not contain all causative HPV types. CONCLUSIONS Individual components of high-grade AIN are caused by single HPV types (the so-called one lesion, one virus concept). HPV16 is causative in <50% of cases. Anal swabs are not useful for detecting lesion-specific HPV types.

Abstract
Objective Anal Intraepithelial Neoplasia (AIN) is present in the majority of HIV+ men who have sex with men (MSM) and routine AIN-screening is subject of discussion. In this study we analysed a wide range of potential risk factors for AIN in order to target screening programs. Methods We screened 311 HIV+ MSM by high resolution anoscopy, with biopsies of suspect lesions. HIV-parameters, previous sexual transmitted infections (STI’s), anal pathology, sexual practices and substance use were analysed in relation to AIN by uni- and multivariable logistic regression. Results AIN (any grade) was found in 175/311 MSM (56%), high grade (HG)AIN in 30%. In the univariable analysis, years since HIV diagnosis, years of antiretroviral therapy (cART) and anal XTC use decreased AIN risk, while a history of anogenital warts and use of GHB (γ-hydroxybutyric acid) increased this risk. In the multivariable analysis three parameters remained significant: years of cART (OR=0.92 per year, p=0.003), anal XTC use (OR=0.10, p=0.002) and GHB use (OR=2.60, p=0.003). No parameters were significantly associated with HGAIN, but there was a trend towards increased risk with anal enema use prior to sex (>50 times ever; p=0.07) and with a history of AIN (p=0.06). CD4 count, STI’s, anal pathology, smoking, number of sex partners and anal fisting were not associated with (HG)AIN. Conclusion GHB use increases the risk for AIN, while duration of cART and anal XTC use are negatively correlated with AIN. Given the high prevalence of AIN in HIV+ MSM, these associations are not helpful to guide a screening program.

Abstract
BACKGROUND High-resolution anoscopy is increasingly advocated to screen HIV+ men who have sex with men for anal cancer and its precursor lesions, anal intraepithelial neoplasia. A systematic comparison between clinical features and the histopathology of suspect lesions is lacking. OBJECTIVE This study aims to analyze interobserver agreement in classifying features of intra-anal lesions suspect for anal intraepithelial neoplasia and to compare these features with their histopathological outcome. DESIGN This study is a cross-sectional survey regarding high-resolution anoscopy with images and biopsies of suspect lesions. Two dermatologists experienced in high-resolution anoscopy, blinded for histopathological outcome, independently classified the lesions on clinical features. SETTING This investigation was conducted at the Dermatology outpatient clinic of the Academic Medical Center in Amsterdam, The Netherlands. PATIENTS Included in the study were 163 HIV+ men who have sex with men, older than 18 years, with no history of anal cancer. MAIN OUTCOME MEASURES The primary outcomes measured were the κ-coefficient for interobserver agreement and the proportions of anal intraepithelial neoplasia per clinical feature. RESULTS Three hundred four biopsies were taken from 163 patients. One hundred sixty-eight biopsies (55%) showed anal intraepithelial neoplasia, and 67/304 (22%) showed high-grade anal intraepithelial neoplasia. The κ-coefficient was 0.65 for condylomatous lesions, 0.14 for surface configuration, 0.54 for punctation, 0.08 for mosaicism, and 0.43 for atypical vessels. Condylomatous lesions showed high-grade anal intraepithelial neoplasia in 18% (95% CI, 11%-27%). In lesions with flat leukoplakia, punctation, and atypical vessels, high-grade anal intraepithelial neoplasia was seen in 25%, 30%, and 23%. In lesions with the combination punctation/atypical vessels and punctation/flat leukoplakia/atypical vessels, high-grade anal intraepithelial neoplasia was found in 38% and 40%. LIMITATIONS We did not take biopsies of healthy-looking mucosa. Furthermore, the real-time description of features during high-resolution anoscopy, instead of the use of images, would improve the recognition of subtle mucosal abnormalities. CONCLUSIONS A moderate to substantial interobserver agreement was demonstrated in recognizing condylomas, punctation, and atypical vessels. Furthermore, high-grade anal intraepithelial neoplasia is present in a high proportion of intra-anal condylomata. A combination of punctation, flat leukoplakia, and atypical vessels is the best predictor for high-grade anal intraepithelial neoplasia.

Abstract
Greater understanding of the role played by human papillomavirus (HPV) in the causation of disease has led to the development of an increasing number of HPV tests with different characteristics. The bewildering choice facing healthcare professionals and providers is daunting. Clearly, HPV testing is no longer simply of research interest, but can provide information that can be used for individual patient management and at the population level for cervical screening and vaccine surveillance. This review aims to provide the background to the development of HPV tests, to explain the different technologies and to discuss the challenges of the application of these optimally in the varied contexts of disease management. Few HPV tests are approved for clinical use and it is important that clinicians understand which test can be utilized, in what circumstances, with what specimens and the meaning of the report issued. HPV testing is no longer applicable only to cervical disease, and we have suggested additional areas, such as the oropharynx, in which HPV testing services might be implemented in the near future. New tests will continue to emerge and we have identified some of the indirect measures of HPV activity, or biomarkers, that could help in the risk stratification of HPV infection and associated disease. The challenges relating to the optimal application of the various HPV technologies are compounded by the lack of evidence regarding their performance in vaccinated populations. Currently published work, including modelling studies, has been undertaken in non-immunized populations. We therefore end by addressing the issues regarding appropriate strategies and tests for immunized populations.

Abstract
Knowledge of human papillomavirus (HPV) type distribution in populations at risk for anal cancer is needed. Here, we describe the anal HPV genotype distribution in a large Spanish cohort (Cohort of the Spanish HIV Research Network HPV [CoRIS-HPV]) of HIV-positive men who have sex with men (MSM) according to geographical origin, age, and cytological status. A cross-sectional analysis of baseline data from 1,439 HIV-infected MSM (2007 to 2012) was performed. Anal HPV genotyping was performed using the Linear Array HPV genotyping test. Descriptive analyses of subject characteristics, prevalences, and 95% confidence intervals (CI) were performed. The global prevalences of HPV, high-risk HPV (HR-HPV), and low-risk HPV (LR-HPV) types were 95.8%, 83.0%, and 72.7%, respectively. Among the HR-HPV types, HPV16 was the most common, followed by HPV59, -39, -51, -18, and -52. The prevalence of multiple HR-HPV infections was 58.5%. There were no differences in the crude analyses between Spanish and Latin-American MSM for most HPV types, and a peak in prevalence for most HPV types was seen in patients in their late thirties. Globally and by specific HPV groups, men with abnormal anal cytologies had a higher prevalence of infection than those with normal cytologies. This study has the largest number of HIV-positive MSM with HPV genotype data analyzed according to cytological status as far as we know. The information gained from this study can help with the design of anal cancer prevention strategies in HIV-positive patients.

Abstract
OBJECTIVES We investigated attitudes about and acceptance of anal Papanicolaou (Pap) screening among men who have sex with men (MSM). METHODS Free anal Pap screening (cytology) was offered to 1742 MSM in the Multicenter AIDS Cohort Study, who reported history of, attitudes about, and experience with screening. We explored predictors of declining screening with multivariate logistic regression. RESULTS A history of anal Pap screening was uncommon among non-HIV-infected MSM, but more common among HIV-infected MSM (10% vs 39%; P < .001). Most participants expressed moderate or strong interest in screening (86%), no anxiety about screening (66%), and a strong belief in the utility of screening (65%). Acceptance of screening during this study was high (85%) across all 4 US sites. Among those screened, most reported it was "not a big deal" or "not as bad as expected," and 3% reported that it was "scary." Declining to have screening was associated with Black race, anxiety about screening, and low interest, but not age or HIV status. CONCLUSIONS This study demonstrated high acceptance of anal Pap screening among both HIV-infected and non-HIV-infected MSM across 4 US sites.
