anal intraepithelial neoplasia

Michele Limoges-Gonzalez, Amar Al-Juburi
Anal squamous cell cancer (SCC) is a relatively uncommon cancer in the United States. Anal SCC has long been associated with human immunodeficiency virus (HIV) positivity and/or men who have sex with men. The incidence of anal SCC has been increasing in both genders regardless of HIV status. Few clinicians are aware that white women, when not controlling for gender and sexual preference together, have the highest incidence of anal SCC. Anal intraepithelial neoplasia (AIN), dysplastic cells of the anal canal due to human papilloma virus infection, is believed to be the precursor to anal SCC...

Tumors and tumorlike conditions of the anus and perianal region originate from the anal canal and anal margin or result from direct extension of tumors from adjacent organs. The anatomy of the anal canal is complex, and its different histologic characteristics can lead to diverse pathologic conditions. The anal canal extends from the anorectal junction to the anal verge. The World Health Organization classification of anal canal tumors includes (a) anal intraepithelial neoplasia, the precursor of squamous cell carcinoma (SCC), and (b) invasive tumors...

BACKGROUND: High-risk human papillomavirus (HPV) is essential for developing high-grade cervical intraepithelial neoplasia (CIN2 and CIN3) and has also been associated with noncervical anogenital cancers. However, limited knowledge exists about the long-term risk for anal, vulvar, and vaginal cancer following CIN2 or CIN3 diagnosis. METHODS: In a nationwide cohort study, we followed nearly 2.8 million women born in 1918-1990 who were recorded as living in Denmark between January 1, 1978 and December 31, 2012...

BACKGROUND: The incidence of anal and cervical cancers and their precursors have increased in the past decades. Women with HIV and sexually transmitted infections are at a higher risk. Cervical human papilloma virus infection may serve as a reservoir and source of anal infection or vice versa. A higher incidence of anal cytological abnormality has been observed in patients with abnormal cervical cytology. OBJECTIVES: This cross sectional study was designed to estimate the prevalence and associations of anal and cervical cytological abnormalities in a cohort of sexually active women using Papanicolaou smears...

The incidence of oropharyngeal cancer (OPC) is significantly increasing in the United States. Given that these epidemiologic trends are driven by human papillomavirus (HPV), the potential impact of prophylactic HPV vaccines on the prevention of OPC is of interest. The primary evidence supporting the approval of current prophylactic HPV vaccines is from large phase 3 clinical trials focused on the prevention of genital disease (cervical and anal cancer, as well as genital warts). These trials reported vaccine efficacy rates of 89% to 98% for the prevention of both premalignant lesions and persistent genital infections...

OBJECTIVE: The aim of this study was to evaluate secretory leukocyte protease inhibitor (SLPI) expression in anal biopsies from HIV-positive (HIV+) individuals, and compare that to anal intraepithelial neoplasia (AIN) diagnoses and human papillomavirus (HPV) status. DESIGN: This is a cross-sectional study of a cohort of 54 HIV+ (31 males and 23 females) from an AIDS clinic in Rio de Janeiro, Brazil. METHODS: The study material consisted of anorectal tissue biopsies obtained from HIV+ subjects, which were used to construct tissue microarray paraffin blocks for immunohistochemical analysis of SLPI expression...

BACKGROUND: The incidences of high-grade anal intraepithelial neoplasia (HSIL) and superficially invasive squamous cell carcinomas (SISCCA) related to human papillomavirus (HPV) have increased. These lesions can progress to invasive anal cancer. The aim of the study was to assess the clinical outcome with a special focus on the healing rate. METHODS: Forty-six consecutive patients (M/F: 35/11; HIV+: 30) with histologically proven HSIL lesions (N=41) or SISCCA (N=5) were enrolled in a follow-up survey...

BACKGROUND: Anogenital warts are often presumed to represent nondysplastic or low-grade anal intraepithelial neoplasia (LGAIN). We previously demonstrated that up to 20% of intra-anal warts in HIV-positive men who have sex with men (MSM) contain regions of high-grade AIN (HGAIN). OBJECTIVES: To determine the causative human papillomavirus (HPV) types of low- and high- grade dysplastic areas in warts from HIV-positive MSM. METHODS: A total of 42 intra-anal warts from 41 HIV-positive MSM were graded as nondysplastic, LGAIN or HGAIN...

INTRODUCTION: The incidence of high-grade anal intraepithelial neoplasia (HGAIN) -with an aetiological based on high-risk types of human papillomavirus- is increasing in some high-risk groups. Screening for HGAIN includes routine anal cytology and, more recently, HPV genotyping. The main objective of this study was to determine the sensitivity and specificity of anal cytology and HPV genotyping for the detection of HGAIN. MATERIALS AND METHODS: This is a study to determine the correlation of cytological and microbiological findings with anal biopsy findings in a cohort of patients at high risk of developing AIN referred to the department of sexually transmitted infections of the Hospital Costa del Sol, Spain, between January 2008 and December 2014...

UNLABELLED: The incidences of human papillomavirus (HPV)-related anal cancer and its precursor lesion, anal intraepithelial neoplasia, are rising in the U.S. and globally. Five-year survival rates with current modalities of treatment for anal cancer are generally favorable for localized and regional disease. For metastatic disease, the relative survival rate is poor. Major contributing factors for the increase in anal cancer incidence include increasing receptive anal intercourse (hetero- and homosexual), increasing HPV infections, and longer life expectancy of treated people who are seropositive for human immunodeficiency virus...

OBJECTIVES: Literature describing the risk factors predisposing inflammatory bowel disease (IBD) patients to anal squamous neoplasia is very scarce. Case reports and small case series have implicated perianal Crohn's disease (CD), long-standing IBD, human papillomavirus (HPV) infection, and immunosuppressive treatment. In this study, we retrospectively examined the association between HPV infection and anal squamous neoplastic lesions among IBD patients from our center. METHODS: We reviewed the pathology records and slides of IBD patients diagnosed with anal squamous cell carcinomas (SCCs), high-grade squamous intraepithelial lesions (HSILs), and low-grade squamous intraepithelial lesions (LSILs) who presented at our center between 1 March 1994 and 9 September 2014...

Condyloma acuminatum (CA) is a common sexually transmitted disease caused by human papilloma virus infection. Not all individuals develop persistent, progressive disease, but careful follow up is required with moderate-to-severe dysplasia to prevent progression to malignancy. Standard therapies include surgical treatments (trans-anal resection and trans-anal endoscopic microsurgery) and immunotherapeutic and topical methods (topical imiquimod); however, local recurrence remains a considerable problem. Here, we report a case with superficial CA of the anal canal, treated with endoscopic submucosal dissection (ESD)...

The incidence of anal cancer is increasing. High risk populations include HIV-positive men who have sex with men (MSM), HIV-negative MSM, HIV-positive women and heterosexual men and women with a history of cervical cancer. HPV has been detected in over 90% of anal cancers. HPV16 is the most common genotype detected in about 70% of anal cancers. The quadrivalent HPV (qHPV) vaccine has been demonstrated to prevent vaccine associated persistent anal HPV infections as well as anal intraepithelial neoplasia grades 2-3 (AIN2+) in young MSM not previously infected...

The prevalence of anal intraepithelial neoplasia has been increasing, especially in high-risk patients, including men who have sex with men, human immunodeficiency virus positive patients, and those who are immunosuppressed. Several studies with long-term follow-up have suggested that rate of progression from high-grade squamous intraepithelial lesions to invasive anal cancer is ∼ 5%. This number is considerably higher for those at high risk. Anal cytology has been used to attempt to screen high-risk patients for disease; however, it has been shown to have very little correlation to actual histology...
