Abstract
OBJECTIVES Anal condylomas are a manifestation of anal human papillomavirus infection and can be associated with precancerous lesions and squamous cell carcinomas. Several methods have been described for treatment, including argon plasma coagulation. A narrative review of the evidence published on this topic was conducted. METHODS A search was conducted using PubMed, Scopus, and Web of Science databases. RESULTS Five studies reported on anal/perianal condyloma treatment with argon plasma coagulation. In 3 of these studies, there was a comparison with other treatment methods (addition of imiquimod, electrofulguration, and electrocautery, respectively). Argon plasma coagulation settings varied between studies. This type of treatment was effective for ablation. Recurrence rates and follow-up times varied largely between studies. No major complications, such as pain, scarring, sexual dysfunction, or severe bleeding were described. CONCLUSION Studies indicate that argon plasma coagulation is an effective and safe therapy for anal and perianal condylomas.

Abstract
Anal pruritus is a common anorectal symptom that can significantly impair a patient’s quality of life, including their mental health. It can be one of the most difficult proctological conditions to treat. Patients often delay seeking medical attention, since it is an embarrassing but non-life-threatening situation. Pruritus ani can be associated with idiopathic and secondary causes, such as anorectal diseases, cancer (anal or colorectal), dermatological and sexually transmitted diseases, fungal infections and systemic diseases. If patients are referred for a colonoscopy, this can sometimes provide the first opportunity to evaluate the perianal area. Classifications of anal pruritus are based on the abnormalities of the perianal skin, one of the most commonly used being the Washington classification. A proper digital anorectal examination is important, as well as an anoscopy to help to exclude anorectal diseases or suspicious masses. Endoscopists should be aware of the common etiologies, and classification of the perianal area abnormalities should be provided in the colonoscopy report. Information on treatment possibilities and follow-up can also be provided. The treatment normally consists of a triple approach: proper hygiene, elimination of irritants, and skin care and protection. Several topical therapies have been described as possible treatments, including steroids, capsaicin, tacrolimus and methylene blue intradermal injections.

Abstract
BACKGROUND We sought to summarize human papillomavirus (HPV) vaccine efficacy/effectiveness (VE) against anal HPV infection and anal intraepithelial neoplasia (AIN). METHODS We performed literature review and meta-analysis to estimate VE, stratified by age and analytic population (per-protocol efficacy [PPE] or intention-to-treat [ITT] population in clinical trials, or all participants in real-world studies). RESULTS We identified 6 clinical trials and 8 real-world studies. In participants vaccinated at age ≤26 years (mainly human immunodeficiency virus [HIV]-negative individuals), significant VE against incident/prevalent anal HPV infection was reported in clinical trials, with a higher estimate in PPE (2 studies with 2390 participants; VE, 84% [95% confidence interval (CI), 77%-90%]; I2 = 0%) than ITT (2 studies with 4885 participants; 55%, 39%-67%; I2 = 46%) populations or in real-world studies (4 studies with 2375 participants; 77%, 40%-91%; I2 = 81%). HPV vaccination at age ≤26 years was associated with significant VE in preventing persistent anal HPV infection and AIN. No significant VE against anal HPV infection or AIN was found in persons vaccinated at age >26 years (mainly people living with HIV). CONCLUSIONS There is strong evidence for high VE against anal HPV infection and AIN in HIV-negative individuals vaccinated at age ≤26 years. However, the lower impact in ITT than in PPE populations and the lack of significant effect in people living with HIV aged >26 years indicates that vaccines have the higher impact in populations with less sexual exposure to anal HPV.

Abstract
ABSTRACT The benefit of treating anal precancerous lesions to reduce anal cancer progression was recently shown in people living with HIV. This will certainly impact the future development of recommendations on anal cancer prevention by including anal precancerous lesions screening and treatment for people living with HIV. However, by bringing this topic to the spotlight, it has also uncovered data that are still missing in this field and that need to be addressed by research.This article will discuss the many unanswered questions about treatment of anal precancerous lesions and future directions for research.

Abstract
BACKGROUND Ulcerative colitis [UC] and Crohn's disease [CD] can be associated with severe comorbidities, namely opportunistic infections and malignancies. We present the first systematic review and meta-analysis evaluating the burden of anal human papillomavirus disease in patients with UC and CD. METHODS PubMed, Web of Science, and Scopus were searched until November 2022. Meta-analyses were performed using random effects models. The protocol was recorded at PROSPERO register with the number CRD42022356728. RESULTS Six studies, including 78 711 patients with UC with a total follow-up of 518 969 person-years, described the anal cancer incidence rate. For anal cancer incidence rate in CD, six studies were selected, including 56 845 patients with a total follow-up of 671 899 person-years. The incidence of anal cancer was 10.2 [95% CI 4.3 - 23.7] per 100 000 person-years in UC and 7.7 [3.5 - 17.1] per 100 000 person-years in CD. A subgroup analysis of anal cancer in perianal CD, including 7105 patients, was calculated with incidence of 19.6 [12.2 - 31.6] per 100 000 person-years [three studies included]. Few studies described prevalence of anal cytological abnormalities [four studies including 349 patients] or high-risk human papillomavirus [three studies including 210 patients], with high heterogeneity. Prevalence of cytological abnormalities or high-risk human papillomavirus was not associated with pharmacological immunosuppression in the studies included. CONCLUSION The incidence of anal cancer is higher in UC than in CD, with the exception of perianal CD. There are limited and heterogeneous data on anal high-risk human papillomavirus infection and squamous intraepithelial lesions prevalence in this population.

Abstract
AbstractThe gold-standard procedure for anal canal examination is anoscopy. Nonetheless, patients are referred for a colonoscopy for many reasons, and a routine exam might provide an opportunity to diagnose anal pathologies, such as hemorrhoids, anal fissures, anal polyps, condylomas, and anal squamous cell carcinoma. It is important to know the main features of these conditions and relevant information to report in order to help guide patient treatment and follow-up.

Abstract
OBJECTIVES Anal squamous cell carcinoma (ASCC) has a higher incidence described in certain groups, namely, in women with vulvar high-grade squamous intraepithelial lesions (vHSILs) and/or human papillomavirus squamous cell carcinoma (VSCC). This review describes terminology, vHSIL, and VSCC in their association with ASCC and the published recommendations for early detection of this cancer in these women. MATERIALS AND METHODS A narrative review was conducted by the authors on vHSIL and VSCC as risk factors for ASCC. RESULTS The ASCC and VSCC incidence are increasing. Women with vHSIL and/or VSCC can present with ASCC at diagnosis, being one of the highest-risk groups. Suspicious symptoms include rectal bleeding, pain, and a sensation of an anal mass. Digital anorectal examination can help detect early ASCC. Sensitivity of anal cytology in women with vHSIL and VSCC seems low, with the exception of immunosuppressed women with genital neoplasia (cervix, vagina, and vulva). There are still insufficient data on high-resolution anoscopy in women with vHSIL and/or VSCC as a screening method. CONCLUSIONS Clinicians need be aware that women with vHSIL and VSCC comprise one of the highest-risk groups for ASCC. Inquiring suggestive symptoms of ASCC and a digital anorectal examination can help in the early detection of this type of cancer.

Abstract
BACKGROUND Perianal Crohn's disease is a disabling condition, with little known about anorectal function in healed/inactive perianal Crohn's disease; Aim: To evaluate anorectal function in a cohort of patients with treated/healed perianal Crohn's disease; Methods: Prospective cohort study, including high-resolution anorectal manometry, balloon expulsion test, and 3D-endoanal ultrasound in all patients; Results: Of the 16 patients studied (mean age ± SD, 42 ± 13 years), 12 (75%) were men. A laceration of the internal anal sphincter and/or anal scarring was seen in nine (56%) patients; there was no laceration of the external anal sphincter. Five (56%) of these nine patients had never experienced faecal incontinence. All had normal anal resting and squeeze pressures. Manometry suggested dyssynergia in 11 (69%) patients, with only one (6%) fulfilling the criteria for obstructed defecation. Hyposensitivity for at least one sensory parameter was seen in 11 (69%) patients and hypersensitivity in five (31%) patients; Conclusions: This study detected sphincter abnormalities in more than half of patients, many of whom were asymptomatic. Alterations in rectal sensation were frequently seen, more commonly with rectal hyposensitivity. TRIAL REGISTRATION ClinicalTrials.gov (NCT03819257).

Abstract
Computer-aided detection algorithms applied to CT lung imaging have the potential to objectively quantify pulmonary pathology. We aim to develop an automatic classification method based on textural features able to classify healthy and pathological patterns on CT lung images and to quantify the extent of each disease pattern in a group of patients with chronic hypersensitivity pneumonitis (cHP), in comparison to pulmonary function tests (PFTs).27 cHP patients were scanned via high resolution CT (HRCT) at full-inspiration. Regions of interest (ROIs) were extracted and labeled as normal (NOR), ground glass opacity (GGO), reticulation (RET), consolidation (C), honeycombing (HB) and air trapping (AT). For each ROI, statistical, morphological and fractal parameters were computed. For automatic classification, we compared two classification methods (Bayesian and Support Vector Machine) and three ROI sizes. The classifier was therefore applied to the overall CT images and the extent of each class was calculated and compared to PFTs. Better classification accuracy was found for the Bayesian classifier and the 16x16 ROI size: 92.1±2.7%. The extent of GGO, HB and NOR significantly correlated with forced vital capacity (FVC) and the extent of NOR with carbon monoxide diffusing capacity (DLCO).Clinical Relevance- Texture analysis can differentiate and objectively quantify pathological classes in the lung parenchyma and may represent a quantitative diagnostic tool in cHP.

Abstract
INTRODUCTION Anal condylomas are associated with human papillomavirus (HPV) infection and are a risk factor for anal squamous cell carcinoma (SCC). OBJECTIVE To conduct a meta-analysis evaluating the prevalence of anal high-risk HPV, high-grade squamous intraepithelial lesions (HSIL) and SCC in patients with condylomas. The standardized incidence ratio (SIR) and the incidence rate of anal SCC were also calculated. METHODS Three electronic databases were searched until April 2020. Meta-analyses were performed using random effects models. RESULTS Pooled prevalence estimate of high-risk HPV (HR-HPV) in anal condylomas was 40.2% (21.0-63.1) in immunocompromised and 16.4% (10.7-24.3) in nonimmunocompromised patients, with an odds ratio (OR) of 3.79 (1.51-9.52, P = 0.005) for immunocompromised patients. HR-HPV in condylomas with HSIL was 73.8% (39.1-92.5) and in non-HSIL cases was 17.7% (9.6-30.2), corresponding to an OR of 12.33 (2.97-51.21, P = 0.001) for those with HSIL. The prevalence of HSIL in condylomas was 24.0% (16.4-33.7) in immunocompromised and 11.8% (7.2-18.8) in nonimmunocompromised patients, with an OR of 2.51 (1.72-3.65, P < 0.001) for immunocompromised patients. The overall prevalence of anal SCC in anal condylomas was 0.3% (0.0-1.7). The SIR of anal SCC was 10.7 (8.5-13.5), 20.1 (14.4-28.2) in men and 7.7 (5.6-10.5) in women. The overall incidence rate of anal SCC was 6.5 per 100 000 person-years (3.6-11.7), 12.7 (9.1-17.8) in men and 4.7 (1.7-13) in women. CONCLUSION Patients with a history of anal condylomas have a high risk of anal SCC, especially men. The prevalence of HR-HPV and HSIL in condylomas from immunocompromised patients is high. This information can change patient follow-up and treatment.

Abstract
Anal squamous cell carcinoma is the most common type of anal cancer and is largely associated with anal human papillomavirus infection. The incidence of anal squamous cell carcinoma is increasing, and although still uncommon in the general population, a high incidence has been noted in specific population groups (eg, patients with HIV, men who have sex with men [MSM], recipients of solid organ transplants, women with genital neoplasia, and patients with systemic lupus erythematosus or inflammatory bowel disease). The higher incidence among individuals who are HIV-positive makes anal squamous cell carcinoma one of the most common non-AIDS-defining cancers among HIV-positive individuals. Anal cancer screening in high-risk groups aims to detect high-grade squamous intraepithelial lesions, which are considered anal precancerous lesions, and for which identification can provide an opportunity for prevention. A blind anal cytology is normally the first screening method, and for patients with abnormal results, this approach can be followed by an examination of the anal canal and perianal area under magnification, along with staining-a technique known as high-resolution anoscopy. Digital anorectal examination can enable early anal cancer detection. Several societies are in favour of screening for HIV-positive MSM and recipients of transplants. There are no current recommendations for screening of anal precancerous lesions via endoscopy, but in high-risk groups, a careful observation of the squamocolumnar junction should be attempted. Several treatments can be used to treat high-grade squamous intraepithelial lesions, including argon plasma coagulation or radiofrequency ablation, which are largely limited by high recurrence rates. Gastroenterologists need to be aware of anal squamous cell carcinoma and anal precancerous lesions, given that patients at high risk are frequently encountered in the gastroenterology department. We summarise simple procedures that can help in early anal squamous cell carcinoma detection.

Abstract
BACKGROUND There is currently a lack of information on full anogenital evaluation of women with a previous history of anogenital neoplasia. METHODS Retrospective analysis of the Homerton Anogenital Neoplasia Service records from January 2012 to March 2017, to identify all new referrals of women with previous anogenital neoplasia, who had had at least one complete examination of all anogenital sites. Multizonal anogenital disease (MZD) was defined as the presence of high-grade squamous intraepithelial lesions (HSIL)/carcinoma concurrently at two or more of the following sites/zones: perianus, anal canal, vulva, vagina or cervix. RESULTS 253 women were included, mean age was 47 (SD=15) years and median duration of follow-up was 12 (IQR=21) months. Fifty-six women (22%) were diagnosed with MZD at first assessment and/or during follow-up. Current smokers (RR=1.84, 95% CI 1.21-2.79, p=0.004) and women on immunodulators/immunosuppressive drugs (RR=2.57, 95% CI 1.72-3.86, p<0.001) had an increased risk for MZD. The risk was lower for women without a previous history of anogenital high-grade lesions/cancer compared to those with this history (RR=0.06, 95% CI 0.01-0.45, p=0.006). CONCLUSIONS Multizonal assessment was important to diagnose occult areas of disease and should be especially considered in current smokers, pharmacologically immunocompromised and those with a previous history of anogenital HSIL/cancer.

A meta-analysis of anal cancer incidence by risk group: Toward a unified anal cancer risk scale. Int J Cancer 2021; 148:38-47. [PMID: 32621759 PMCID: PMC7689909 DOI: 10.1002/ijc.33185] [Citation(s) in RCA: 225] [Impact Index Per Article: 75.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/07/2020] [Revised: 06/11/2020] [Accepted: 06/17/2020] [Indexed: 12/23/2022]
Abstract
Certain population groups are known to have higher than average anal cancer risk, namely persons living with HIV (PLHIV), men who have sex with men (MSM), women diagnosed with human papillomavirus (HPV)-related gynecological precancerous lesions or cancer, solid organ transplant recipients (SOTRs) and patients with autoimmune diseases. Our aim was to provide robust and comparable estimates of anal cancer burden across these groups. Summary incidence rates (IRs), as cases per 100 000 person-years (py), were calculated by fixed-effects meta-analysis. IRs were 85 (95% confidence interval [CI] = 82-89) for HIV-positive MSM (n = 7 studies; 2 229 234 py), 32 (95% CI = 30-35) for non-MSM male PLHIV (n = 5; 1626 448 py) and 22 (95% CI = 19-24) for female PLHIV (n = 6; 1 472 123 py), with strong variation by age (eg, from 16.8 < 30 years to 107.5 ≥ 60 years for HIV-positive MSM). IR was 19 (95% CI = 10-36) in HIV-negative MSM (n = 2; 48 135 py). Anal cancer IRs were much higher after diagnosis of vulvar (IR = 48 [95% CI = 38-61]; n = 4; 145 147 py) than cervical (9 [95% CI = 8-12]; n = 4; 779 098 py) or vaginal (IR = 10 [95% CI = 3-30]; n = 4; 32 671) cancer, with equivalent disparity after respective precancerous lesions. IR was 13 (95% CI = 12-15) in SOTRs (n = 5; 1 946 206 py), reaching 24.5 and 49.6 for males and females >10 years after transplant. Anal cancer IRs were 10 (95% CI = 5-19), 6 (95% CI = 3-11) and 3 (95% CI = 2-4) for systemic lupus erythematosus, ulcerative colitis and Crohn's disease, respectively. In conclusion, a unifying anal cancer risk scale, based upon comprehensive meta-analysis, can improve prioritization and standardization in anal cancer prevention/research initiatives, which are in their public health infancy.

Burden of anal squamous cell carcinoma, squamous intraepithelial lesions and HPV16 infection in solid organ transplant recipients: A systematic review and meta-analysis. Am J Transplant 2020; 20:3520-3528. [PMID: 32343489 DOI: 10.1111/ajt.15942] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/18/2019] [Revised: 03/30/2020] [Accepted: 04/10/2020] [Indexed: 01/25/2023]
Abstract
The number of solid organ transplant recipients (SOTR), and their life expectancy, is increasing, with higher risk for long-term complications from immunosuppression. We carried out a systematic review describing the burden of anal squamous cell carcinoma (SCC), and its surrogates, in SOTR. We conducted mixed effect model-based meta-analyses evaluating incidence of anal SCC (standardized incidence ratio [SIR] vs general population, and absolute incidence rate [IR]), prevalence of anal squamous abnormalities, and human papillomavirus (HPV) 16. Generalized I2 statistics were calculated, quantifying heterogeneity. Anal SCC incidence in SOTR was elevated vs the general population (pooled SIR = 6.8, 95% confidence interval [CI], 4.3-10.9; 6 studies including 241 106 SOTR; I2 = 82.3%), with an absolute IR of 12.3 (95% CI, 10.4-14.7) per 100 000 person-years (5 studies including 1 079 489 person-years; I2 = 0%). Prevalence of abnormal anal cytology was 12.9% (95% CI, 9.2%-17.7%; 6 studies including 328 SOTR; I2 = 17.4%). For histology, the pooled prevalence estimate of anal squamous intraepithelial lesions was 22.4% (95% CI, 17.3%-28.5%; 3 studies including 214 SOTR; I2 = 0%), with 4.7% (95% CI, 2.5%-8.5%; I2 = 0%) high-grade squamous intraepithelial lesions. Pooled anal HPV16 prevalence was 3.6% (95% CI, 1.6%-7.8%; 4 studies including 254 SOTR; I2 = 17.6%). There was substantial and consistent evidence of elevated anal SCC incidence in SOTR.
