Anal squamous cell carcinoma (SCC) is the fourth most prevalent cancer in human immunodeficiency virus (HIV)-infected men who have sex with men (MSM). Human papillomavirus (HPV) has been detected in over 90% of anal carcinoma biopsy specimens from MSM, and is considered a necessary, but alone, insufficient factor for carcinogenesis. Anal intraepithelial neoplasia (AIN) may be precursive for SCC, and screening cytology with referral of persons with abnormality for high-resolution anoscopy-guided biopsy, and AIN treatment, has been recommended for prevention...

REVIEW
Joseph R Roberts, Lacey L Siekas, Andrew M Kaz
Anal intraepithelial neoplasia (AIN) is a premalignant lesion of the anal mucosa that is a precursor to anal cancer. Although anal cancer is relatively uncommon, rates of this malignancy are steadily rising in the United States, and among certain high risk populations the incidence of anal cancer may exceed that of colon cancer. Risk factors for AIN and anal cancer consist of clinical factors and behaviors that are associated with the acquisition and persistence of human papilloma virus (HPV) infection. The strongest HPV-associated risk factors are HIV infection, receptive anal intercourse, and high risk sexual behavior...

OBJECTIVE: To assess risk factors of high-grade anal intraepithelial neoplasia (HGAIN) recurrence in a cohort of HIV-infected MSM. DESIGN AND METHODS: Consecutive HIV-infected 100 MSM with a history of successfully treated intra-anal HGAIN with electrocautery were followed with anal cytology, human papillomavirus (HPV) determination, and high-resolution anoscopy (HRA) at 3-6-month intervals. HGAIN recurrence was analyzed using Kaplan-Meier analysis. Risk factors of recurrence were assessed using Cox proportional hazards regression...

RATIONALE: Patients with human immunodeficiency virus (HIV) infection have been shown to be at increased risk for high-risk human papillomavirus (HR-HPV) infection of the anogenital tract. Furthermore, in the last decades, the introduction of highly active antiretroviral therapy (HAART) has increased the longevity of these patients who now live long enough to develop HPV-related cancers; hence, the impact of HPV infection on HIV-positive patients is of increasing concern. PATIENT CONCERNS: We reported the case of an HIV-positive female patient on HAART with a good virological and immunological response and with a long history of HPV-related intraepithelial and invasive lesions of the anogenital tract...

BACKGROUND: Anal canal high-grade squamous intraepithelial lesion (HSIL) is the precursor to anal cancer. Immunocompromised patients are at increased risk and disease is usually within 3 cm from the anal verge. High-resolution anoscopy (HRA) with an 8-cm anoscope is used to identify and guide cautery treatment of HSIL. PURPOSE: We report three patients with a long-term history of ulcerative colitis (UC) treated with systemic immunomodulators who developed proximally located rectal HSIL...

BACKGROUND: Human immunodeficiency virus (HIV)-infected women have a higher burden of anal high-grade squamous intraepithelial lesions (HSIL) and anal cancer (AC) compared with HIV-uninfected women. Guidelines for AC screening in this population are heterogeneous. Here we report outcomes and risk factors for anal HSIL following implementation of universal AC screening offered to all HIV-infected women. METHODS: Data from women who underwent AC screening with anal cytology from April 2009 to July 2014 were analyzed...

PURPOSE OF REVIEW: Anal cancer is a serious health problem in HIV-positive men who have sex with men, and precursor lesions, anal intraepithelial neoplasia, are well defined. Given the similarities with cervical cancer, screening for and treatment of anal intraepithelial neoplasia might prevent anal cancer. Screening programmes should meet the Wilson and Jungner criteria. We used these criteria to evaluate the current body of evidence supporting a screening programme for anal dysplasia...

Introduction Anal carcinoma represents an increasing problem in HIV-infected patients. Anal intraepithelial neoplasia (AIN), the precursor lesion, is currently diagnosed by high-resolution anoscopy (HRA) using optical magnification derived from gynecological colposcopy. This prospective study evaluates anal chromoendoscopy (ACE) using standard gastroenterological video-endoscopes in diagnosing AIN. Methods After clinical examination, proctoscopy and surface staining with acetic acid followed by Lugol's solution, ACE was performed with a mucosectomy cap on the tip of the endoscope...

PURPOSE: Radiofrequency ablation (RFA) effectively treats esophageal high-grade dysplasia, but its efficacy in treating anal canal high-grade squamous intraepithelial lesions (HSILs) is unsubstantiated. This prospective study assessed the safety and efficacy of applying hemi-circumferential RFA to anal canal HSIL. METHODS: Twenty-one HIV-negative participants with HSIL occupying ≤ half the anal canal circumference were treated with hemi-circumferential anal canal RFA...

BACKGROUND: There is debate about the accuracy of anal cytology and high-resolution anoscopy (HRA), in the diagnosis of anal human papillomavirus (HPV)-related squamous intraepithelial lesions (SIL). Few studies have performed both simultaneously in a large sample of high-risk individuals. METHODS: At baseline in a community-based cohort of HIV-infected and uninfected homosexual men ages ≥35 years in Sydney, Australia, all men underwent anal swabbing for cytology and HPV genotyping, and HRA-guided biopsy...

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...
