Abstract
INTRODUCTION Metastatic anal squamous cell carcinoma (SCC) carries a poor prognosis and the evidence base for surgical resection of metastases remains limited. The aim of this study was to establish the survival outcomes for patients undergoing metastasectomy for anal SCC. METHODS A systematic review was performed using the MEDLINE®, Embase®, Cochrane and PubMed® databases. Studies were considered for inclusion in the review if they involved patients aged >18 years with a diagnosis of stage IV anal SCC who underwent metastasectomy for liver and/or lung metastases. The primary outcome measure was overall survival. Secondary outcome measures were disease free survival, early morbidity according to the Clavien-Dindo classification and quality of life, measured using a validated scoring tool. Risk of bias was assessed with the ROBINS-I (Risk Of Bias In Non-randomised Studies - of Interventions) tool. RESULTS There were 10 studies with a total of 98 patients. There was heterogeneity in results reporting, with recurrence free survival the most reported outcome. For all studies reporting on liver metastasectomy, the one-year overall survival rate was 87%. In studies with adequate follow-up reported, the three and five-year overall survival rates were 53% and 38% respectively. Only one study reported on lung metastasectomy patients; the overall median survival was 24 months. None of the studies reported on quality of life measures. The ROBINS-I tool identified a critical risk of bias in six studies, a serious risk in one study and a moderate risk in three studies. CONCLUSIONS The evidence base for metastasectomy in metastatic anal SCC is limited. Further information is required to inform future treatment methods and use of a standardised outcomes reporting method is needed to support this.

Abstract
Anal cancer, mainly squamous cell carcinoma, is rare but increasing in prevalence, as is its precursor lesion, anal squamous dysplasia. They are both strongly associated with human papillomavirus infection. The 2-tiered Lower Anogenital Squamous Terminology classification, low-grade SIL and high-grade SIL, is preferred to the 3-tiered anal intraepithelial neoplasia classification because of better interobserver agreement and clearer management implications. Immunohistochemistry with p16 is helpful to corroborate the diagnosis of squamous dysplasia. Similarly, immunohistochemistry is helpful to differentiate primary Paget disease from secondary Paget disease, which is usually due to anal squamous mucosal/epidermal involvement by primary rectal adenocarcinoma.

Abstract
BACKGROUND Perianal malignancies are rare tumors with unique presentations and treatment options. OBJECTIVE To review published literature about primary malignancies that present on perianal skin and published guidelines and treatment options. MATERIALS AND METHODS A PubMed search was conducted for original articles about perianal malignancies. RESULTS Squamous cell carcinoma, basal cell carcinoma, melanoma, and extramammary Paget disease are the most common tumors to present on perianal skin. Anal squamous cell carcinoma incidence is increasing and certain populations may benefit from screening. Surgical management is often recommended for localized perianal tumors. CONCLUSION Dermatologic surgeons should be familiar with the presentation and treatment options available for perianal malignancies.

Abstract
INTRODUCTION Physicians must share decisions and choose personalised treatments regarding patients´ beliefs and values. OBJECTIVE To analyse the quality of the recommendations about shared decision making (SDM) in colorectal (CRC) and anal cancer treatment clinical practice guidelines (CPGs) and consensus statements (CSs). METHODS Guidelines were systematically reviewed following prospective registration (Prospero: CRD42021286146) without language restrictions searching 15 databases and 59 professional society websites from January 2010 to November 2021. A validated 31-item SDM quality assessment tool was employed to extract data in duplicate. RESULTS We identified 134 guidelines. Only 46/134 (34.3 %) mentioned SDM. Fifteen (11.1 %) made clear, precise and actionable recommendations, while 9/134 (6.7 %) indicated the strength of the SDM-related recommendations. CPGs underpinned by systematic reviews reported SDM more often than those based on consensus or reviews (35.9 % vs 32.0 %; p = 0.031). Guidelines that reported following quality tools (i.e., AGREE II) more commonly commented about SDM than when it was not reported (75.0 % vs 32.0 %; p = 0.003). CONCLUSION AND PRACTICE IMPLICATIONS Most of the CRC and anal treatment guidelines did not mention SDM and it was superficial. Guidelines based on systematic reviews and those using quality tools demonstrated better reporting of SDM. Recommendations about SDM in these guidelines merit urgent improvement.

Abstract
OBJECTIVE The objective of this review is to synthesize the best evidence available to determine the prevalence and incidence of anal cancer in HIV-positive men. INTRODUCTION Worldwide, an estimated 50,685 people were diagnosed with anal cancer in 2020 and an estimated 19,293 people died from the disease during the same year. From 2001 to 2015, the overall incidence of anal cancer increased by 2.7% per year, while mortality jumped by 3.1% each year. Evidence has shown that anal intraepithelial neoplasia can progress to cancer over time, particularly within the immunocompromised population. INCLUSION CRITERIA This review will consider studies conducted in any setting, in any geographical location that report on the prevalence and incidence of adult males aged 18 years or older from any racial or ethnic background who are HIV positive and diagnosed with any type of anal cancer. Participants will be included regardless of stage of anal cancer, type of cancer treatment used, or length of time diagnosed. METHODS CINAHL, MEDLINE, Embase, LBGTQ+ Source (EBSCO), Web of Science Core Collection, MedNar, WorldWideScience, and ProQuest Dissertations and Theses databases will be searched from 1990 till the present. Analytical and descriptive observational studies will be included and critically appraised by 2 independent reviewers. Data will be extracted using JBI standardized data extraction tools. If sufficient data are available, a meta-analysis will be conducted; otherwise, the findings will be presented in narrative format, including tables and figures to aid in data presentation. REVIEW REGISTRATION PROSPERO CRD42022327933.

Abstract
In developed countries the incidence of anal squamous cell carcinoma (SCC) has been rising; especially in women over the age of 60 years who present with more advanced disease stage than men. Historically, anal SCC screening has focused on people living with Human Immunodeficiency Virus (HIV) (PLWH) who are considered to be at the highest risk of anal SCC, and its precancerous lesion, anal squamous intraepithelial lesion (SIL). Despite this, women with vulval high-grade squamous epithelial lesions (HSIL) and SCCs have been shown to be as affected by anal HSIL and SCC as some PLWH. Nevertheless, there are no guidelines for the management of anal HSIL in this patient group. The ANCHOR trial demonstrated that treating anal HSIL significantly reduces the risk of anal SCC in PLWH, there is therefore an unmet requirement to clarify whether the screening and treatment of HSIL in women with a prior genital HSIL is also beneficial. This review presents the current evidence supporting the screening, treatment, and surveillance of anal HSIL in high-risk women with a previous history of genital HSIL and/or SCC.

Prevalence of anal dysplasia and HPV genotypes in gynecology patients: The ANGY cross-sectional prospective clinical study protocol. PLoS One 2022; 17:e0276438. [PMID: 36269726 PMCID: PMC9586359 DOI: 10.1371/journal.pone.0276438] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/02/2022] [Accepted: 09/18/2022] [Indexed: 11/06/2022] Open
Abstract
BACKGROUND Human Papillomaviruses (HPV) are highly prevalent in the sexually active populations, with a significant burden in terms of health and psychological cost in all class ages. High-risk (HR) HPV genotypes are associated with anogenital dysplasia and cancers, and anal HPV-induced cancer is increasingly observed in women. The interactions of HPV genotype's between the anus and the cervix, and the subsequent occurrence of dysplasia remains unclear. This clinical study set out to test the hypothesis that risk factors for anal HR-HPV and dysplasia may differ in women with or without cervical dysplasia or in HIV-positive women. METHODS Cervical and anal HPV genotypes and cytology testing will be performed prospectively in a cohort of women recruited in a tertiary university hospital in Switzerland. Women will be allocated to three groups: 1) normal previous cervical smear; 2) high-grade cervical dysplasia (H-SIL) at previous cervical smear; 3) HIV+, independently of previous cervical smear result. General inclusion criteria comprised the followings: Female-Age > = 18 years; Satisfactory understanding of French; No objection to HIV testing. Specific inclusion criteria are: Group 1, no past or current gynecological dysplasia and HIV negative; Group 2, Gynecological dysplasia (H-SIL) or carcinoma in situ demonstrated by histology (vulvar, vaginal or cervical) and HIV negative; Group 3: HIV-positive (regardless of viremia or CD4 count) with or without gynecological dysplasia. General exclusion criteria are: Pregnancy; History of anal dysplasia/cancer; Status after pelvic radiotherapy; Absence of anus and anal canal. Estimated prevalences of anal dysplasia are: in group 1, 1% (0-2%); in group 2, 15% (5-27%), and in group 3, 30% (19-45%). With a 10% margin error, a sample size of 120 women per group is required to reach 90% power for detecting statistical significance (unilateral α error of 5%). DISCUSSION The primary endpoint is the prevalence of anal and cervical dysplasia, and description of the respective HPV genotypes in each group. The results of this study could improve the standard of screening of cervical and anal dysplasia in women through evidence of concomitant presence of HPV's and/or dysplasia in anus or cervix to support vaccination for instance. Beginning of recruitment started in September 2016. Results should be presented in end of 2022. Preliminary analysis for first 100 patients reveals that the mean age of the population is 39.6 (± 10.9) years with mean age of first sexual intercourse of 18.5 (± 3.9) years. In this cohort, 12% are vaccinated and 38% having had anal intercourse. Overall, 43% of the studied population had cervical HR-HPV in the studied population, and 53% had normal cytology. Anal LR HPV and HR HP were found in 27.6% and 38.4% of all patients respectively. Eighty percent had normal anal cytology. Groups 1,2 and 3 had a significant difference in terms of age, gestity, parity, age of first sexual intercourse, systematic use of condom, number of cervical LR HPV and HR HPV and abnormal cervical cytologies. TRIAL REGISTRATION The study was approved by the institutional review board-CER-VD#2015-00200-on the 29th of June 2016 and is registered on the Swiss National Clinical Trials Portal (SNCTP), SNCTP000002567, Registered 29 June 2016, https://www.kofam.ch/en/snctp-portal/study/40742/.

Abstract
Background and Aims The standard treatment for invasive squamous cell anal cancer is chemoradiation treatment. However, treatment options for high-grade dysplasia (squamous cell cancer in situ) are either surgical excision or topical treatment modalities. There are a few case reports, mainly from Japan, about resecting early squamous cell anal cancer (high-grade dysplasia/carcinoma in situ) by endoscopic submucosal dissection. We present a case series of 3 patients from a western hemisphere population with squamous carcinoma in situ of the anal canal resected with endoscopic submucosal dissection (ESD). Methods This is a retrospective series of 3 patients from a western hemisphere population with squamous carcinoma in situ of the anal canal resected with ESD. All patients were referred from the oncology team after declining surgical excision. Results Microscopically margin-negative en bloc resection was achieved in all patients. All patients were free from dysplasia or cancer on their latest endoscopic surveillance, ranging from 10 months to 26 months after ESD. One patient had a small lesion on follow-up 3 months after ESD that was removed by a curative EMR. There were no immediate or delayed adverse events. Conclusions ESD can be used to resect squamous cell carcinoma in situ of the anal canal. Larger studies with long-term follow-up are needed to evaluate the role of ESD in early squamous cell anal cancer and to compare it with other modalities of treatment.

Abstract
The social stigma surrounding an anal cancer diagnosis has traditionally prevented open discussions about this disease. However, as recent treatment options and an increasing rate of diagnoses are made worldwide, awareness is growing. In the United States alone, 9,090 individuals were expected to be diagnosed with anal cancer in 2021. The US annual incidence of squamous cell carcinoma of the anus continues to increase by 2.7% yearly, whereas the mortality rate increases by 3.1%. The main risk factor for anal cancer is a human papillomavirus infection; those with chronic immunosuppression are also at risk. Patients with HIV are 19 times more likely to develop anal cancer compared with the general population. In this review, we have provided an overview of the carcinoma of the anal canal, the role of screening, advancements in radiation therapy, and current trials investigating acute and chronic treatment-related toxicities. This article is a comprehensive approach to presenting the existing data in an effort to encourage continuous international interest in anal cancer.

Abstract
Background Recommendations in clinical practice guidelines (CPGs) may be reversed when evidence emerges to show they are futile or unsafe. In this study, we identified and characterized recommendation reversals in gastroenterology CPGs. Methods We searched CPGs published by 20 gastroenterology societies from January 1990 to December 2019. We included guidelines which had at least two iterations of the same topic. We defined reversals as when (a) the more recent iteration of a CPG recommends against a specific practice that was previously recommend in an earlier iteration of a CPG from the same body, and (b) the recommendation in the previous iteration of the CPG is not replaced by a new diagnostic or therapeutic recommendation in the more recent iteration of the CPG. The primary outcome was the number of recommendation reversals. Secondary outcomes included the strength of recommendations and quality of evidence cited for reversals. Results Twenty societies published 1022 CPGs from 1990 to 2019. Our sample for analysis included 129 unique CPGs. There were 11 recommendation reversals from 10 guidelines. New evidence was presented for 10 recommendation reversals. Meta-analyses were cited for two reversals, and randomized controlled trials (RCTs) for seven reversals. Recommendations were stronger after the reversal for three cases, weaker in two cases, and of similar strength in three cases. We were unable to compare recommendation strengths for three reversals. Conclusion Recommendation reversals in gastroenterology CPGs are uncommon but highlight low value or harmful practices.

Abstract
High grade anal intraepithelial neoplasia due to human papilloma viral (HPV) infections is a precursor lesion for squamous cell carcinoma especially in high risk populations. Frequent examination and anal biopsies remain unpopular with patients; moreover they are also risk factors for chronic pain, scarring and sphincter injury. There is lack of uniform, surveillance methods and guidelines for anal HPV specifically the intervals between exam and biopsies. The aim of this editorial is to discuss the intervals for surveillance exam and biopsy, based on specific HPV related biomarkers? Currently there are no published randomized controlled trials documenting the effectiveness of anal screening and surveillance programs to reduce the incidence, morbidity and mortality of anal cancers. In contrast, the currently approved screening and surveillance methods available for HPV related cervical cancer includes cytology, HPV DNA test, P16 or combined P16/Ki-67 index and HPV E/6 and E/7 mRNA test. There are very few studies performed to determine the efficacy of these tests in HPV related anal pre-cancerous lesions. The relevance of these biomarkers is discussed in this editorial. Longitudinal prospective research is needed to confirm the effectiveness of these molecular biomarkers that include high risk HPV serotyping, P16 immuno-histiochemistry and E6/E7 mRNA profiling on biopsies to elucidate and establish surveillance guidelines.

Comparing and contrasting clinical consensus and guidelines for anal intraepithelial neoplasia in different geographical regions. Updates Surg 2021; 73:2047-2058. [PMID: 34482519 PMCID: PMC8606379 DOI: 10.1007/s13304-021-01156-7] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/09/2021] [Accepted: 08/23/2021] [Indexed: 12/03/2022]
Abstract
Anal Squamous Cell Carcinoma (ASCC) is an uncommon cancer with a recognised precursor Anal Intraepithelial Neoplasia (AIN). Although there are consistent evidence-based guidelines for the management of ASCC, historically this has not been the case for AIN and as a result there have been geographical variations in the recommendations for the treatment of AIN. More recently there have been updates in the literature to the recommendations for the management of AIN. To assess whether we are now closer to achieving an international consensus, we have completed a systematic scoping review of available guidelines for the screening, treatment and follow-up of AIN as a precursor to ASCC. MEDLINE and EMBASE were systematically searched for available clinical guidelines endorsed by a recognised clinical society that included recommendations on either the screening, treatment or follow-up of AIN. Nine clinical guidelines from three geographical areas were included. The most recent guidelines agreed that screening for AIN in high-risk patients and follow-up after treatment was necessary but there was less consensus on the modality of screening. Six Guidelines recommended the treatment of high-grade AIN and four guidelines describe a follow-up protocol of patients diagnosed with AIN. There appears to be increasing consensus on the treatment and follow-up of patients despite a poor evidence base. There is still significant discrepancy in guidance on the method to identify patients at risk of ASCC and AIN despite consensus between geographical regions on which patient subgroups are at the highest risk.

Abstract
Coronavirus 2019 disease (COVID-19) has created major impacts on public health. The virus has plagued a large population requiring hospitalization and resource utilization. Knowledge about the COVID-19 virus continues to grow. It can commonly present with gastrointestinal symptoms; initially, this was considered an atypical presentation, which led to delays in care. The pandemic has posed serious threats to the care of anorectal diseases. Urgent surgeries have been delayed, and the care of cancer patients and cancer screenings disrupted. This had added to patient discomfort and the adverse outcomes on healthcare will continue into the future. The better availability of personal protective equipment to providers and standard checklist protocols in operating rooms can help minimize healthcare-related spread of the virus. Telehealth, outpatient procedures, and biochemical tumor marker tests can help with mitigation of anorectal-disease-related problems. There is limited literature about the clinical management of anorectal diseases during the pandemic. We performed a detailed literature review to guide clinicians around management options for anorectal disease patients. We also highlighted the health challenges seen during the pandemic.

Abstract
BACKGROUND The development of high-resolution anoscopy (HRA) has advanced our ability to detect anal dysplasia. Historically, HRA is performed in a clinical setting and subsequent ablation is performed in the clinical setting or operating room. The aim of this study was to determine the most effective venue for the performance of HRA. METHODS Following institutional review board (IRB) approval, the correlation between anal cytology and HRA performed in the clinic versus in the operating room was evaluated. Data were extracted from our IRB-approved prospective HRA database over the time period of 2013-2017. RESULTS One hundred twenty-eight HRAs were compared (101 in the clinical setting, 27 in the operating room). There was a statistically significant difference in the correlation between anal cytology and HRA pathology for procedures performed in the clinical setting (55% [56/101]) versus those performed in the operating room (82% [22/27]) (p = 0.014). More biopsies were obtained in the operating room than in the clinic setting (3 vs. 1, p < 0.0001). The majority of patients who had HRA in a clinical setting with subsequent HRA in the operating room stated that they preferred to have their HRAs performed in the operating room due to discomfort from the HRA procedure. CONCLUSIONS Detection rates for anal dysplasia on HRA, are significantly higher when performed in the operating room. To prevent discomfort in the clinical setting, patients with high-grade dysplasia on anal pap testing may benefit from proceeding directly to the operating room for concurrent HRA and ablation.

Incidence of radiation induced sarcoma attributable to radiotherapy in adults: A retrospective cohort study in the SEER cancer registries across 17 primary tumor sites. Cancer Epidemiol 2021; 70:101857. [PMID: 33249363 PMCID: PMC7856279 DOI: 10.1016/j.canep.2020.101857] [Citation(s) in RCA: 12] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/16/2020] [Revised: 10/13/2020] [Accepted: 11/01/2020] [Indexed: 01/05/2023]
Abstract
BACKGROUND Previous studies have noted the incidence of radiation-induced sarcomas (RIS) but have not investigated the relative risk (RR) of developing RIS based on primary tumor organ disease site. By examining data from the Surveillance, Epidemiology, and End Results (SEER) database, we hypothesized that breast cancer would have a higher incidence of RIS compared to seventeen other primary cancer sites. METHODS This was a retrospective cohort study that examined patients from SEER registries between 1973 and 2013. We included patients aged 18 years or older who were diagnosed with cancer and those diagnosed with a cancer who subsequently developed a sarcoma. We excluded patients with missing information on initial radiotherapy treatment or stage. RIS was defined as those who developed a secondary sarcoma near the site of their original malignancy and after a 24-month latency period. RESULTS Our patients had a mean age of 60 years and follow up time of 9.2 years. Breast cancer comprised the majority with 693,701(36.8%) patients of which 161 (0.02%) had a secondary sarcoma. Of the 359 patients with secondary sarcomas, 242 (67.4%) had RIS. Breast cancer had the highest number of RIS patients at 126 compared to all combined non-breast cancer sites at 116. The RR of RIS in breast cancer versus 19 other primary cancer sites was 1.21 (CI: 1.01-1.45, p < 0.03, adjusted for age at primary diagnosis, gender, and latency). CONCLUSIONS Our study demonstrated that breast cancer has a higher risk of developing RIS compared to other solid cancers.

Abstract
AIM As the understanding of anal dysplasia continues to develop, controversy remains regarding treatment of these lesions. The purpose of this study was to evaluate lesion type (flat vs exophytic) and the association between morphology and dysplasia. METHODS This was a single-centre retrospective analysis of a prospectively collected pathological database of patients > 17 years old who underwent operative excision/biopsies for presumed anal condyloma or dysplasia from 2009 to 2018. The analysis includes comparisons between patient factors, phenotype and grade of dysplasia. RESULTS Sixty-nine patients had 423 lesions. The mean age of the study population was 48.2 years. 62.3% were men and 46.4% of patients were black. 47.8% of patients were human immunodeficiency virus (HIV) positive and 39.1% were men who have sex with men (MSM). There were 176 (41.6%) flat lesions and 234 (55.3%) exophytic lesions. Exophytic lesions were 2.5-fold more likely to be associated with a higher grade of dysplasia than flat lesions (OR 2.63, 95% CI 1.09-6.32). Neither lesion type nor dysplasia severity was associated with human papillomavirus, lesion location or patient characteristics, including race, MSM or HIV status. DISCUSSION Exophytic lesions were more than twice as likely to have advanced dysplasia compared with flat lesions. A clearer understanding of the association between gross lesion appearance and dysplasia will allow more appropriate counselling of patients and the development of better screening and treatment guidelines for anal condylomata and dysplasia.

Abstract
BACKGROUND Anal SCC is a rare disease mainly treated with chemoradiation. Abdominoperineal resection (APR), once the mainstay of treatment for anal cancer, now serves a role as salvage therapy for persistent or recurrent disease after chemoradiation. In addition, clinically positive nodes are currently treated by extending the radiation field to the groin. The role of inguinal lymph node dissection in recurrent or persistent anal SCC is unclear. The aim of the study is to determine the role of inguinal lymph node dissection in the management of inguinal lymph node metastasis for anal squamous cell carcinoma (SCC). METHODS Retrospective analysis of patients with anal SCC in the National Cancer Database with positive inguinal nodes undergoing salvage APR between 2004 and 2014 was performed. A comparison of overall survival between patients who underwent APR with lymph node dissection versus APR only was analyzed using Kaplan-Meier plot. RESULTS A total of 3424 patients underwent salvage APR, with 274 (8%) having clinically positive nodes. Within the subgroup that had clinically positive nodes, 195 (71%) underwent APR, whereas 79 (29%) underwent both APR and node dissection. Kaplan-Meier analysis demonstrates no difference in overall survival in the two groups (P = 0.99). Five-year survival for both groups was similar (36% versus 42%; P = 0.987). No significant difference was found when adjusted for age, gender, and Tumor Node Metastasis staging. CONCLUSIONS Inguinal lymph node dissection does not appear to improve overall survival in patients with advanced-stage anal cancer requiring salvage APR. Proper patient selection for node dissection is essential to spare patients from additional morbid procedures.

Abstract
OBJECTIVES There are no uniform screening recommendations for anal cancer. Medical practice guidelines are now available on the use of Digital Anal Rectal Examinations (DARE) for the detection of anal cancer; however, because screening can result in more harm than benefit, our objective was to assess the evidence for use of DARE as a public health screening tool. MATERIALS AND METHODS We conducted a current critical appraisal of anal cancer literature using World Health Organization criteria for assessing the potential utility of a public health screening program. RESULTS Digital Anal Rectal Examination satisfies most, but not all, World Health Organization criteria for a public health program that seeks to detect early invasive anal cancer in populations at high risk for anal cancer, most notably HIV-positive men who have sex with men; however, DARE is not appropriate when facilities for treatment are nonexistent. In addition, there are insufficient data on DARE sensitivity and specificity. CONCLUSIONS The mildly invasive nature of DARE, limited likelihood of adverse procedure-related events, cost-effectiveness and patient acceptability, as well as wide availability of DARE support consideration of its integration into screening for populations at high risk of anal cancer, especially HIV-positive men who have sex with men.

Abstract
PURPOSE Therapy of anal cancer follows national and international guidelines that are mainly derived from randomized trials. This study aimed to analyze long-term results of stage-dependent treatment of anal cancer in a non-selected patient cohort. PATIENTS AND METHOD All consecutive patients treated for anal cancer between 2000 and 2015 were retrieved from a prospective database. Risk-dependent screening for human immunodeficiency virus showed no infection. Main outcome measure was overall survival with respect to tumor site and treatment. Secondary endpoints were cause-specific survival, stoma free survival, and the rate of salvage operations. RESULTS In total, 106 patients were treated for anal cancer. Of those, 69 (65.1%) suffered from anal canal cancer and 37 (34.9%) from anal margin cancer. Three patients with synchronous distant metastases were excluded from analysis. The majority of patients (n = 79, 76.7%) were treated by chemoradiotherapy in curative intention. Twenty-two patients underwent local surgery. Five-year overall survival was 73.1% and cause-specific survival at 5 years was 87.4%. Overall, 14 patients (13.6%) needed salvage surgery. Their 5-year cause-specific survival was 57.7%. A permanent ostomy was avoided in 77.7%. CONCLUSIONS Treatment of anal cancer results in low rates of salvage surgery and permanent ostomies, when therapy was determined by a multidisciplinary team following national and international guidelines.

Abstract
Background: Anal cancer incidence is increasing in the US. Though formally established national anal cancer screening guidelines are nonexistent, many providers advocate screening to avoid late disease presentation. This study assesses the knowledge, attitudes, and practices of anal cancer screening among providers to identify the degree of variation and barriers to screening.
Methods: Healthcare providers from two academic medical centers and a statewide community primary care group were surveyed using a questionnaire adapted from the National Survey of Primary Care Physicians’ Recommendations and Practice for Cancer Screening. Descriptive statistics were performed to explore providers’ responses and Fisher’s exact test to explore variation.
Results: 86 providers completed the questionnaire (response rate 24.2%): 81.4% physicians, 18.6% advanced practitioners. 48.2% of respondents perform anal cancer screening. 5.8% correctly identified all high-risk patient factors. “HIV+ patient” was identified most frequently as high-risk (93.5%), “organ transplant recipient” (42.9%) least frequently. Anal pap test was the most recommended first-line screening test (76.6%) followed by digital anorectal exam (19.2%), HPV test (8.5%), and high-resolution anoscopy (HRA) (6.4%). Clinical evidence (72.3%) and national guidelines (70.2%) were most influential in guiding providers’ screening recommendations. Lack of qualified screening providers (34.1%), lack of patient follow-up after positive test results (22.7%), and patient non-compliance to initial screening (15.9%) were identified as “usual” barriers.
Conclusions: Anal cancer screening attitudes and practices vary among providers. Development of national practice guidelines that define a multidisciplinary team approach from primary care anal cancer screening to specialist referral for HRA may reduce screening variability.

Abstract
Anal cancer is a heterogeneous and rare disease process that accounts for ∼1.5% of all gastrointestinal tract malignancies. The perianal skin plays host to a variety of different premalignant and malignant lesions, all with variable histology, treatment options, and prognosis. Anal cancers in general are notorious for having a delayed or missed diagnosis leading to treatment delays and may have an impact on survival. This delay is in part due to the nonspecific symptomatology and also improper physical examination of the sensitive and anatomically complex perianal region and anal canal. This article examines the various types of perianal cancers and their precursor lesions and will explore treatment options as well as outcomes and prognosis.

Abstract
A 58-year-old man presented to colorectal clinic with intermittent rectal bleeding, weight loss, also pain and weakness affecting his lower back and right leg. On inspection, there were perianal warts (condyloma acuminata), with an additional palpable anal lesion on digital rectal examination, confirmed by colonoscopy. Subsequent imaging revealed a large right psoas abscess, and an associated paravertebral soft tissue component invading the right lumbosacral plexus and nerve roots at L4, L5 and S1. Biopsy of the paravertebral mass revealed metastatic squamous cell carcinoma. Given his symptomatology, and also as biopsy of the perianal warts revealed high-grade squamous intraepithelial lesion/grade III anal intraepithelial neoplasia on histology with infection by human papillomavirus type 6, the primary was presumed to be anal. This was a case of sciatic pain which proved to be diagnostically challenging on initial presentation to primary care. This mode of presentation and pattern of metastasis are uncommon in anal cancer.

Abstract
AIM Up to 30% of patients with squamous cell cancer of the anus (SCCA) will require a salvage abdominoperineal resection (APR) for either persistent or recurrent disease. The objective of this study was to assess cancer-related outcomes in patients with (i) persistent or (ii) recurrent SCCA. METHOD Embase and MEDLINE were searched. Publications were included if they assessed overall survival (OS), disease-free survival (DFS) and locoregional recurrence or metastatic disease after salvage APR for persistent or recurrent SCCA. RESULTS A total of 28 retrospective case series (study size ranged from nine to 111) met our inclusion criteria. The median time to salvage APR was 2.6 months [interquartile range (IQR) 2.6-5.0 months, six studies] for persistent disease and 27.6 months (IQR 15.0-32.7 months, five studies) for recurrent disease. The median 5-year OS from the time of salvage APR was 45.0% (IQR 32.0%-52.3%, 10 studies) for persistent disease and 51.0% (IQR 36.0%-60.9%, 11 studies) for recurrent disease. The median 5-year DFS following salvage APR was 44.0% (IQR 29.5%-53.0%, 10 studies) for all patients. Following salvage APR, the median locoregional recurrence rate was 23.5% (IQR 15.8%- 46.9%, 19 studies) and 9.0% (IQR 6.4%-13.3%, 16 studies) of patients developed metastatic disease after salvage APR. CONCLUSION Our review characterizes the best evidence for outcomes following salvage APR for patients with persistent or recurrent SCCA. The evidence is limited by the quality of included studies, as many were single centre case series.

Abstract
BACKGROUND/OBJECTIVES The first-line treatment for anal squamous cell carcinoma is Nigro protocol chemoradiotherapy. Some patients will fail curative intent chemoradiotherapy and have persistent disease while others may have an initial response followed by disease recurrence. The goal of this study is to investigate survival in anal squamous cell carcinoma patients who fail first-line treatment. METHODS The National Cancer Database (2004-2013) was used to identify patients with anal squamous cell carcinoma. The primary outcome was overall survival. RESULTS There were 256 patients in the early salvage group who underwent abdominoperineal resection (APR) within 6 months of completing chemoradiotherapy and 181 patients in the late salvage group who had APR 6 months or more after completion of chemoradiotherapy. Both groups of patients had similar tumor size (45 vs 50 mm; P = 0.07) and rate of positive margins (21.5% vs 15.6%;P = 0.13). There was no significant difference in overall survival between early and late salvage APR (hazard ratio [HR]: 0.81; 95% confidence interval [CI]: 0.50-1.32; P = 0.40). CONCLUSIONS The overall survival of anal squamous cell carcinoma patients undergoing early vs late salvage APR after failure of chemoradiotherapy is similar. As a result, patients with persistent disease should be offered surgery just as readily as those with recurrent disease.

Abstract
Anal intraepithelial neoplasia (AIN) is a premalignant lesion for anal cancer. It is more commonly found in high-risk patients (e.g., human papilloma virus (HPV)/human immunodeficiency virus infections, post-organ transplantation patients, and men who have sex with men) and development is driven by HPV infection. The incidence of AIN is difficult to estimate, but is heavily skewed by preexisting conditions, particularly in high-risk populations. The diagnosis is made from cytology or biopsy during routine examinations, and can be performed at a primary care provider’s office. A pathologist can then review and classify cells, based on nucleus-to-cytoplasm ratios. The classification of low or high grade can better predict progression from AIN to anal cancer. There is little debate that AIN can develop into anal cancer, and the main rationale for treatment is to delay the progression. Significant controversy remains regarding screening, surveillance, and treatment for AIN. Management options are separated into surveillance (watchful waiting) and interventional strategies. Emerging data suggest that close patient follow up with a combination of ablative and topical treatments may offer the greatest benefit. HPV vaccination offers a unique treatment prior to HPV infection and the subsequent development of AIN, but its use after the development of AIN is limited. Ablative treatment includes excision, fulguration, and laser therapy.

Abstract
BACKGROUND The risk of anal carcinoma after previous diagnosis of anal intraepithelial neoplasia III is unclear. OBJECTIVE The purpose of this study was to estimate the risk of anal carcinoma in patients with anal intraepithelial neoplasia III and to identify predictors for subsequent malignancy. DESIGN This was a retrospective review using the Surveillance, Epidemiology, and End Results registry (1973-2014). SETTING The study was composed of population-based cancer registries from the United States. PATIENTS Patients who were diagnosed with anal intraepithelial neoplasia III were included. MAIN OUTCOME MEASURES The primary outcome was rate of subsequent anal squamous cell carcinoma. Predictors for anal cancer were identified using logistic regression and Cox proportional hazard models. RESULTS A total of 2074 patients with anal intraepithelial neoplasia III were identified and followed for a median time of 4.0 years (interquartile range, 1.8-6.7 y). Of the cohort, 171 patients (8.2%) subsequently developed anal cancer. Median time from anal intraepithelial neoplasia III diagnosis to anal cancer diagnosis was 2.7 years (interquartile range, 1.1-4.5 y). Fifty-two patients (30.4%) who developed anal carcinoma were staged T2 or higher. Ablative therapies for initial anal intraepithelial neoplasia III were associated with a reduction in the risk of anal cancer (OR = 0.3 (95% CI, 0.1-0.7); p = 0.004). Time-to-event analysis revealed that the 5-year incidence of anal carcinoma after anal intraepithelial neoplasia III was 9.5% or ≈1.9% per year. LIMITATIONS The registry did not record HIV status, surveillance schedule, use of high-resolution anoscopy, or provider specialty. CONCLUSIONS In the largest published cohort of patients with anal intraepithelial neoplasia III, ≈10% of patients were projected to develop anal cancer within 5 years. Nearly one third of anal cancers were diagnosed at stage T2 or higher despite a previous diagnosis of anal intraepithelial neoplasia III. Ablative procedures were associated with a decreased risk of cancer. This study highlights the considerable rate of malignancy in patients with anal intraepithelial neoplasia III and the need for effective therapies and surveillance.

Abstract
Anal intraepithelial neoplasia (AIN) and anal squamous cell carcinoma (ASCC) are on the rise in the United States, especially among men who have sex with men, HIV-positive or other immunocompromised patients, and women with a history of cervical, vaginal, or vulvar cancer. Strong evidence supports the human papillomavirus as the causative factor in anal dysplasia; reducing the risk of HPV infection can reduce rates of ASCC. High-risk patients should be screened for AIN, but no universal screening guidelines exist, and more studies are needed to develop a national protocol for screening and management of patients with AIN.

Abstract
The incidence of anal intraepithelial neoplasia (AIN) has been increasing over the years. AIN acts as a precursor lesion for anal squamous cell cancer. Factors leading to progression of AIN into malignancy are complex and involve grade of the lesion, human papillomavirus and HIV coinfection, as well as patient-related risk factors such as immunocompromised state and men who have sex with men. The multifaced aspects of this disease make its management challenging, as it involves several disciplines including pathology, primary care, infectious disease, and colorectal specialties. Each of these fields brings its own expertize to the management of AIN, and their collaborative, coordinated work culminates into best practice and optimized outcomes in the care of the AIN patient.

Abstract
Human papillomavirus (HPV) infection is responsible for 4.3% of the global cancer burden. Since 2006, current HPV vaccines have reduced the prevalence of the virus in adolescent girls, reduced the prevalence of genital warts, and been proven to reduce the progression of anal intraepithelial neoplasia in men. Herein, we review the epidemiology, virology, and immunology behind the prophylactic HPV vaccines and current recommendations for its use. We also review future immune therapies being trialed for use against HPV-related cancers including anal cancer.

Abstract
Anal intraepithelial neoplasia (AIN) is the premalignant condition of the anal squamous tissue. It is associated with the human papilloma virus and is considered the transition prior to the invasive anal squamous cell carcinoma. It is typically asymptomatic and can be either an incidental finding after anorectal surgery or identified when high-risk patient populations are screened. Once AIN is diagnosed, the optimal management remains controversial, partly because the natural history of the disease is unclear. Surgical management of the disease has essentially been replaced by more conservative treatment options and can range from expectant management to topical therapy to photodynamic therapy. The aim of this article is to review the varied treatment options and to briefly review prevention strategies.

Abstract
Anal cancer is a rare condition, although its incidence has been increasing over the past several decades, particularly in women. The majority of anal cancers are squamous cell cancers and are linked with human papilloma virus (HPV) infection. Recent work in HPV basic science has delineated the mechanism by which the virus leads to the development of anal cancer. With widespread availability of an HPV vaccine since 2006, vaccination has become an important strategy for anal cancer prevention. However, in the US, there remain no guidelines for anal cancer screening. Treatment of anal cancer is dictated largely by accurate staging, which is generally accomplished with a combination of physical exam, magnetic resonance imaging, computed tomography, and positron emission tomography. Chemoradiation remains the mainstay of treatment for most patients, with surgery reserved for salvage therapy. Recent trials have identified the optimal use of available chemotherapeutics. Exciting developments in immune therapies targeting HPV oncoproteins as well as therapeutic vaccines may soon dramatically change the way patients with anal cancer are managed.

Abstract
BACKGROUND Anal intraepithelial neoplasia (AIN) is dysplasia in the epithelium of the anus and is a pre-malignant condition associated with a low rate of progression to invasive squamous cell carcinoma (SCC). The natural history of progression for AIN to anal SCC is poorly defined. This study aims to review our experience with AIN and investigate the natural history of progression. METHODS Data on all patients with AIN from January 2005 to December 2015 were retrospectively reviewed. Three separate databases were searched - Colorectal, Radiation Oncology and Infectious Diseases. All databases were cross-referred to obtain a complete but non-duplicated data set. Electronic charts were reviewed to obtain clinical information. RESULTS Twenty-eight patients were identified with AIN of various grades. There were 25 males, three females. Twenty of the male patients were human immunodeficiency virus (HIV) positive. Mean length of follow up was 56 months. Complete regression of AIN to normal was noted in 13 patients (46%). Four patients had persisting AIN III with no evidence of regression or malignant transformation. Nine patients with pre-existing AIN developed SCC (32%). Seven were positive for HIV infection (all males). Median time to progression was 36 months. None of the patients demonstrated clear linear pattern of progression of AIN to SCC. CONCLUSION High grade AIN may progress to anal SCC and surveillance is indicated. The exact natural history of progression for AIN is difficult to predict. There is no linear progression over time evident. HIV patients with AIN are at higher risk of developing SCC.

Abstract
OPINION STATEMENT Assessing the quality of health care delivered is a priority across medical specialties, but it is particularly critical for radiation oncology, a field with rapid introduction of new technologies and treatment paradigms. Deviation from acceptable standards can lead to delivery of inferior therapies and medical errors that can directly compromise patient clinical outcome, thus leading to disparities in quality of care. Professional oncologic specialty societies often take ownership of standardizing best practices by issuing evidence-based disease-specific consensus guidelines. They also inform quality indicators that are set as requirements for accreditation, maintenance of certification, and reimbursement. Cooperative groups also create benchmarks for quality radiation therapy through design of clinical protocols that set standard-of-care treatment practices. Pelvic radiotherapy for colorectal and anal cancers has undergone a significant transformation in radiation planning and delivery including increased complexity in contour segmentation with a transition from three-dimensional to intensity-modulated radiation therapy (IMRT). Compliance with quality metrics proposed in national consensus guidelines and participation in clinical trials help keep practicing radiation oncologists up-to-date with advances in our field and well-trained to provide safe and effective high-value care.

Abstract
BACKGROUND Human papillomavirus is a common sexually transmitted infection that may affect the oropharynx, genitalia, or anus. Some strains of this virus may cause bulky growths around the anus known as giant anal condylomas. These can become large, disfiguring, and may cause bleeding, as well as difficulty with defecation and hygiene. Surgical management is usually necessary for large condylomas, whereas office-based procedures are common for smaller lesions. It is unclear why some develop large anal margin tumors, whereas others develop limited disease. The aim of the present study was to evaluate for risk factors that may play a role in the development of extensive disease warranting operative management. MATERIALS AND METHODS A retrospective chart review of patients seen within the Anal Dysplasia Clinic at the Medical College of Wisconsin was undertaken. Clinic encounters for patients with anogenital condyloma were abstracted for demographic information, operative interventions, Human Immunodeficiency Virus status, and smoking history to determine risk factors that predicted operative intervention for giant anal condylomas. RESULTS A total of 239 patients met inclusion criteria; 211 (88.3%) were male and 28 (11.7%) were female. Racial makeup of the cohort included 49% Caucasian, 38.9% African-American, 9.2% Hispanic, and 2.9% were identified as another ethnicity. One hundred forty-three patients (60.1%) were current or past smokers. One hundred ninety-eight (82.8%) patients tested positive for human immunodeficiency virus (HIV), whereas 41 (17.2%) were negative. Multiple linear regression identified only African-American race as predictive of greater disease burden. CONCLUSIONS African-American race was associated with increased size of anal condyloma. As the size of anal condylomas increase, management shifts from topical treatments to operative intervention. This is the first study to correlate race with burden of disease in the general population.

Abstract
A broad spectrum of pathology affects the rectum, anus, and perineum and understanding of its relevant anatomy is important in accurate reporting, particularly in rectal cancer. In this pictorial essay, correlative imaging, endoscopic, pathologic, and operative images are presented to illustrate normal anorectal anatomy and neoplastic conditions that affect the anus and rectum. A particular case-based focus is given to rectal adenocarcinoma with pelvic MR and surgical histopathology. Additionally, carcinoid tumor, gastrointestinal stromal tumor, condylomata acuminata, squamous cell carcinoma, melanoma, and metastatic disease about the rectum and anus are reviewed.

Abstract
PURPOSE OF REVIEW No single modality of care serves as the defined best practice for the treatment of anal intraepithelial neoplasia (AIN). This review aims to present the common treatment modalities germane to AIN while considering evolving evidence. RECENT FINDINGS AIN affords an opportunity to evaluate and treat patients before the development of invasive diseases. Efforts to screen for AIN have yielded mixed results. The major available pharmacotheraputic and surgical options offer efficacious options to reduce the bioburden of disease but can be met with high levels of recurrent disease. None affords a predictably durable response in severe disease. Vaccination as primary prevention will likely reduce the overall upward trend in AIN. Evidence suggests vaccination also affords improvement in recurrent disease. Early evidence reveals potential benefit in multimodal approaches to control AIN. Valuable data is anticipated from the phase III, randomized ANCHOR study evaluating the management of high-grade AIN in HIV +patients.

Abstract
Anal cancer incidence and mortality have been increasing over the past decade. Although the incidence in the general population remains low, it is much higher in certain subgroups, including those living with human immunodeficiency virus and men who have sex with men. Approximately 90% of anal squamous cell cancers are caused by infection with carcinogenic human papillomavirus (HPV). Given the common etiology between anal and cervical carcinogenesis, screening for anal cancer has been proposed in certain high-risk populations using strategies adapted from cervical cancer prevention. In this review, the authors discuss important differences in anal and cervical cancer regarding the populations at risk, disease natural history, and clinical procedures and outcomes that need to be considered when evaluating strategies for anal cancer screening. They also performed a systematic review and meta-analysis of the performance of anal cytology, anal HPV testing, and various biomarkers for the detection of anal precancers and cancers. The implications of these performance estimates are summarized in the context of risk-based screening and management of anal precancers, and important research gaps are highlighted that need to be addressed to fully understand the benefits and harms of anal cancer screening.

Abstract
BACKGROUND While intensity modulated radiotherapy (IMRT) has been widely adopted for the treatment of anal cancer (AC), the added contour complexity poses potential risks. This study investigates the impact of contour variation on tumour control probability (TCP) when using IMRT for AC. METHODS Nine Australian centres contoured a single computed tomography dataset of a patient with AC. The same optimised template-based IMRT planning protocol was applied to each contour set to generate nine representative treatment plans and their corresponding dose volume histograms. A geometric analysis was performed on all contours. The TCP was calculated for each plan using the linear quadratic and logitEUD model. RESULTS The median concordance index (CI) for the bladder, head and neck of femur, bone marrow, small bowel and external genitalia was 0.94, 0.88, 0.84, 0.65 and 0.65, respectively. The median CI for the involved nodal, primary tumour and elective clinical target volumes were 0.85, 0.77 and 0.71, respectively. Across the nine plans, the TCP was not significantly different. Variation in TCP between plans increased as tumour cell load increased or radiation dose decreased. CONCLUSIONS When using IMRT for AC, contour variations generated from a common protocol within the limits of minor deviations do not appear to have a significant impact on TCP. Contouring variations may be more critical with increasing tumour cell load or reducing radiotherapy dose.
