CONTEXT: - The incidence of anal cancer in the United States is on the rise in high-risk populations. The anal Papanicolaou test (APT) is advocated as a screening tool, in addition to digital rectal examination and high-resolution anoscopy. OBJECTIVE: - To review our experience and the current literature to create, in cooperation with clinicians, a standardized screening and treatment algorithm given our large volume of APTs. DATA SOURCES: - All APTs collected between January 2013 and June 2015 were reviewed and correlated with follow-up/concurrent biopsy diagnoses, and clinical and social history...

The prevalence of Human Papillomavirus (HPV) in men who have sex with men (MSM) is high, reaching 85-93% prevalence in HIV-positive men. High-risk HPV are strongly associated with development of high degrees of anal intraepithelial neoplasia (AIN) which, later on, can develop in anal squamous carcinoma. The growing incidence of anal cancer during last years is particularly important in MSM and HIV-positive patients, in which the coexistence of multiple serotypes of HPV reduces the probability of eliminating the AIN...

BACKGROUND: Sexually transmitted infection (STI) rates are increasing in the U.S. while funding for prevention and treatment programs has declined. Sample self-collection for STI testing in men may provide an acceptable, easy, rapid and potentially cost-effective method for increasing diagnosis and treatment of STIs. METHODS: We conducted a systematic review of articles assessing self-collection of anal, oral, or genital swab samples among adult men for detection of STIs and/or human papillomavirus (HPV)-related dysplasia...

Progression of anal intraepithelial neoplasia (AIN) involves transition from productive to transforming human papillomavirus (HPV) infection. Grading aims to distinguish productive low-grade AIN from high-grade anal intraepithelial neoplasia (HGAIN) with risk of cancer. We describe immunohistochemical patterns in AIN adding a novel marker for initiation of the productive phase of the HPV life cycle (panHPVE4) to those for cell cycle activity (Ki-67) and transforming activity of HPVE7 gene (p16). We studied 67 anal biopsies for suspected anal neoplasia (17 normal, 15 AIN1, 20 AIN2, 15 AIN3) from 54 men who have sex with men at New York Presbyterian Hospital, USA...

p16 is the most widely studied biomarker in lower anogenital tract squamous intraepithelial lesions and, currently the only recommended biomarker for histological grade assessment. The aim of this systematic review and meta-analysis was to evaluate p16-positive rates according to anal squamous intraepithelial lesions/anal intraepithelial neoplasia (AIN) grade. Two investigators independently searched four electronic databases: PubMed, Web of Sciences, Scopus, and Embase from inception until August 2017. Studies that evaluated p16 immunostaining in histological samples of anal and/or perianal squamous intraepithelial lesions and defined a p16-positive result as diffuse block staining with nuclear or nuclear plus cytoplasmic staining were included...

The incidence of anal cancer has been rising, especially in HIV+ patients and has been associated with HPV infection. HIV+ patients are more at risk of HPV coinfection and are seven times more likely to have persistent HPV infection; moreover, HIV+ men have an increased risk of developing anal cancer compared to HIV+ women. The development of screening strategies for the detection of HPV in HIV+ men is of major importance; however, there is not enough information about the HPV genotypes and variants that are colonizing the anal epithelia of HIV+ men in diverse geographical regions...

The epidemiology of anal cancer in the U.S. has changed over the past 3 decades. During this period the incidence of anal cancer has increased among both men and women. Of note, women with a history of anogenital HPV infection are at higher risk than the general population for anal cancer. The increased risk ranged from increased incidence rate ratios ranging from 1.82 to 6.3 in women with a history of cervical cancer, to 4.2-16.4 in women with a history of prior cervical intraepithelial neoplasia 3 (CIN 3)...

BACKGROUND: Anal intraepithelial neoplasia is associated with high-risk human papillomavirus (hrHPV) as a precursor to anal cancer. However, factors other than hrHPV are likely to be involved and further study of cofactors is required because of the possibility of syndemic interactions. METHODS: Three hundred and fourteen patients underwent 457 operations. Histopathology and hrHPV testing using the Digene Hybrid Capture 2 (HC 2) method were performed. Demographic factors and sexually transmissible infections (STIs) were recorded...

Purpose: The incidence of invasive anal cancer (IAC) has been increasing among human immunodeficiency virus (HIV)-positive men who have sex with men (MSM). Although cytological diagnosis is the modality of choice for screening cases of IAC, it is associated with lower sensitivity and specificity. Therefore, the present study aimed to evaluate new cytological signs of human papillomavirus (HPV) infection that may contribute to improving anal cytology. Methods: Anal cytology and HPV testing were performed using SurePath liquid-based cytology on samples obtained from 37 HIV-positive Japanese MSM...

OBJECTIVE: Anal cytology is being increasingly used as part of anal cancer screening in patients at high risk for anal neoplasia. Most studies in anal cytology have focused on correlating the abnormal anal Pap smear with histopathologic outcomes. The aim of this study was to document histopathologic or repeat anal cytology outcomes in patients with unsatisfactory cytology. MATERIALS AND METHODS: Unsatisfactory anal Pap tests in high risk male patients were correlated with follow-up histopathologic diagnoses or cytology...

BACKGROUND: Anal intraepithelial neoplasia grade 2 (AIN2) and AIN grade 3 (AIN3) are commonly grouped together as high grade squamous intraepithelial lesions (HSIL). We assessed risk factors for HSIL-AIN2 and HSIL-AIN3 in a cohort of homosexual men. METHODS: At the baseline visit in the Study for the Prevention of Anal Cancer (SPANC), all men completed a questionnaire and underwent anal swabbing for cytology and HPV genotyping, followed by high resolution anoscopy...

OBJECTIVE: HIV-positive MSM are at increased risk for developing anal squamous cell carcinoma. Detection of precursor lesions of anal cancer [anal high-grade squamous intraepithelial lesions (HSIL)] is cumbersome and expensive. Our objective was to identify potential risk factors for anal HSIL in HIV-positive MSM to develop more stringent screening criteria. DESIGN: We studied a cohort of MSM screened by high-resolution anoscopy at three HIV clinics in Amsterdam, the Netherlands...

BACKGROUND: Human papillomavirus (HPV) is the leading cause of cervical cancer and other malignant and benign neoplastic lesions. HPV vaccination has three potential goals: to prevent transmission, infection, and disease. At present, there are no available data about health consequences of HPV immunization in Italy. The aim of this study is to evaluate the effect of current HPV vaccination strategy in Italy. METHODS: A multistate morbidity-mortality model was developed to estimate the infection process in a theoretical cohort of Italian women...

Anal cancer is biological similar to cervical cancer, and is preceded by anal intraepithelial neoplasia (AIN). Screening for AIN and treatments to reduce the risk of anal cancer are not established as guidelines of care for HIV-infected patients. It is mainly because screening and treating of AIN is not yet proven to reduce the incidence of anal cancer. The present study preliminarily demonstrated that a successful screening program in preventing squamous cell anal cancer in HIV positive patients. The authors achieved their purpose of controlling the evolution of all abnormalities identified during the anal cancer screening, preventing AIN to progress towards anal cancer, and reversing any form of AIN by surgery, ablation or medical therapy...
