Hewitt A, Kawak S, Yang Q, Stafford LC, Bailey HH, Striker R, Hayden DM, Sanger CB. Risk of developing high-grade squamous intraepithelial lesions or anal cancer after anal condylomata treatment in people living with HIV. Colorectal Dis 2024. [PMID: 39099077 DOI: 10.1111/codi.17099] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/10/2024] [Revised: 05/23/2024] [Accepted: 06/25/2024] [Indexed: 08/06/2024]
Abstract
AIM To assess the risk and natural history of developing advanced anal disease after diagnosis of anal condyloma in people living with HIV (PLWH). METHODS This was a single-centre retrospective cohort study of PLWH and anal condyloma from 2001 to 2021. Patients who developed advanced anal disease (AAD; anal high-grade squamous intraepithelial lesions and/or anal cancer) were compared to those who did not progress (non-AAD). We assessed the potential association between AAD and condyloma location, recurrence, and treatment modality. AAD-free survival was calculated utilizing Kaplan-Meier methods. RESULTS A total of 118 PLWH and anal condyloma were included. Mean overall follow-up time was 9.3 years. A total of 31% of patients developed AAD (n = 37). Average time to AAD from condyloma diagnosis was 5.6 years. On multivariate analysis, risk for AAD development was associated with perianal location of condyloma (OR 4.39, p = 0.038) and increased time from initial condyloma diagnosis (OR 1.12, p = 0.008). Higher CD4/CD8 ratios were associated with lower risk of AAD (OR 0.15, p = 0.029). Condyloma recurrence and treatment type were not associated with development of AAD. AAD-free survival was longer in those with intra-anal only condyloma versus those with either perianal disease alone or combined intra-anal/perianal disease (mean survival times: 22.8 vs. 8.7 vs. 10.7 years, p = 0.017). CONCLUSION Our study demonstrates the need for careful, long-term follow-up of PLWH and condyloma, particularly in the setting of perianal disease and low CD4/CD8 ratio. Risk of anal disease progression is present even in the setting of condyloma regression following treatment.

Abstract
Endoanal ultrasound (EAUS) is a valuable imaging modality for the evaluation of anal and perianal pathologies. It provides detailed information about the anatomy and physiology of the anorectal region and has been used in pre-and post-operative settings of anorectal pathologies. EAUS is not only useful in the evaluation of benign pathologies but also in loco-regional staging of anal and rectal tumors. EAUS has several advantages over MRI, including reduced cost, better patient tolerance, and improved scope of application in patients with contraindications to MRI. Despite its benefits, EAUS is not widely performed in many centers across the globe. This article aims to educate radiologists, trainees, and surgeons about the indications, contraindications, patient preparation, imaging technique, and findings of EAUS. We will also highlight the technical difficulties, diagnostic challenges, and procedural complications encountered during EAUS, along with a comparative analysis of EAUS with other imaging approaches.

Abstract
OBJECTIVES This study aimed to determine if immune inflammatory markers (neutrophil lymphocyte ratio [NLR], platelet lymphocyte ratio [PLR], and prognostic nutritional index [PNI]) correlate with anal cancer risk in people living with HIV and to compare these markers with the CD4/CD8 ratio. MATERIALS AND METHODS This is a regional retrospective cohort study of veterans living with HIV who were screened for or diagnosed with anal neoplasia or cancer from 2001 to 2019. The NLR, PLR, PNI, and CD4/CD8 ratio within 1 year of anal pathology results were computed. Patients with anal cancer were compared to patients without anal cancer. Regression modeling was used to estimate the odds of developing anal cancer. RESULTS Three hundred thirty-four patients were included (37 with anal cancer, 297 without anal cancer). In patients with anal cancer, NLR and PLR were higher (2.17 vs 1.69, p = .04; 140 vs 110, p = .02, respectively), while PNI and CD4/CD8 ratio were lower (44.65 vs 50.01, p < .001; 0.35 vs 0.80, p < .001, respectively). On multivariate logistic regression modeling, only PNI (odds ratio, 0.90; p = .001) and CD4/CD8 ratio (odds ratio, 0.05; p < .001) were associated with increased anal cancer risk. CONCLUSIONS Although NLR and PLR independently correlate with anal cancer risk, when controlling for other risk predictors, only PNI and CD4/CD8 ratio were statistically significant biomarkers for anal cancer. The CD4/CD8 ratio is the strongest immune inflammatory marker that predicts risk of anal cancer among veterans living with HIV.

Abstract
BACKGROUND Solid organ transplantation is a risk predictor for virally-mediated anal squamous intraepithelial lesions and cancer (anal disease). Precancerous squamous intraepithelial lesions can be detected by screening, and treatment may prevent cancer progression. Screening recommendations are not well defined. We aim to define prevalence and describe risk predictors for anal disease in a large population of solid organ transplant recipients. METHODS Retrospective single-center cohort analysis included solid organ transplant recipients cared for between 2001 and 2022 (N = 15 362). The cohort of recipients who developed anal disease was compared with those who did not. Greedy propensity score matching was performed for organ-specific recipients, and time-to-event analysis for the development of anal disease was performed in those with genitourinary human papilloma virus (HPV) disease versus those without. RESULTS Prevalence of anal disease was 0.6% (cancer 0.2%). The average years from transplant to the diagnosis of anal disease was 11.67. Anal disease was more common in women (68.5% versus 31.5%, P < 0.001), patients who had other HPV-related genitourinary diseases (40.4% versus 0.6%, P < 0.001), who were of younger age at transplant (39.62 versus 46.58, P < 0.001), and had increased years from transplant (17.06 versus 12.57, P < 0.001). In multivariate analysis, the odds of anal disease increased by 4% each year posttransplant. History of genitourinary HPV disease (odds ratio 69.63) and female sex (odds ratio 1.96) were the most significant risk predictors for anal disease. CONCLUSIONS The prevalence of anal cancer among solid organ transplant recipients was equal to the general population (0.2%). Due to the low prevalence of overall disease, these data suggest that anal screenings in transplant recipients should be targeted to higher-risk subsets: female recipients farther out from transplant and patients with genitourinary HPV-related diseases.

Abstract
Anal intraepithelial neoplasia (AIN) are precancerous lesions and are sequela of human papilloma virus (HPV) infection. AIN is classified as low-grade squamous intraepithelial lesion or high-grade squamous intraepithelial lesion. Screening with anal cytology and anoscopy should be considered for high-risk populations. Diagnosis is made through high resolution anaoscopy and biopsy. Options for treatment include ablation and several topical therapies; however, recurrence rates are high for all treatment options, and an ongoing surveillance is necessary to prevent progression to anal squamous cell carcinoma. HPV vaccination is recommended to prevent disease.

Abstract
This study aimed to provide comprehensive clinical screening data for anal intraepithelial neoplasia (AIN). This study included 312 patients who underwent high-resolution anoscopy (HRA) examinations between January 1, 2020 and April 15, 2024. Clinical data, including demographic information, clinical history, cytology/high-risk human papilloma virus (hrHPV) results, and HRA records, were analyzed. The median age of all patients was 42 years (interquartile range: 33-52 years). Approximately 26.3% reported a history of VIN2/3+, 13.5% had a history of VaIN2/3+, 29.8% had a history of CIN2/3+, 44.6% had persistent cervical HPV16 infection, and 12.5% had immune suppression. Among the 312 patients, 14.4% were diagnosed with AIN2/3, 25.0% with AIN1 and 60.6% were normal. Anal cytological abnormalities were found in 41.3% of all patients, with a significantly higher rate in AIN2/3 patients than in ≤AIN1, 71.1% versus 36.3%, p < 0.001. The hrHPV positivity rate was 89.7%, with HPV16 being the most prevalent. The complete agreement rate for HRA impressions was 79.5%. Multi-variable analysis revealed immune suppression (odds ratio [OR]: 3.47, 95% confidence interval [CI]: 1.42-8.5) and VIN2/3+ (OR: 2.82, 95% CI: 1.27-6.28) were independent risk factors for AIN2/3. Abnormal cytology results (OR: 3.3, 95% CI: 1.52-7.17) and anal HPV16 infection (OR: 3.2, 95% CI: 1.26-8.12) demonstrated similar ORs for AIN2/3. Early screening for AIN2/3+ is crucial in Chinese women with lower genital tract precancerous and cancerous lesions, particularly in those with VIN2/3+ and immune suppression.

Abstract
PURPOSE To investigate the differences in baseline staging of anal squamous cell carcinoma based on CT, MRI, and PET/CT, and the resultant impact on the radiation plan. METHODS This retrospective study included consecutive patients with anal squamous cell carcinoma who underwent baseline pelvic MRI, CT, and PET/CT (all examinations within 3 weeks of each other) from January 2010 to April 2020. CTs, MRIs, and PET/CTs were re-interpreted by three separate radiologists. Several imaging features were assessed; tumor stage was determined based on the eight edition of the American Joint Committee on Cancer (AJCC) staging manual; and T (tumor), N (node), and M (metastasis) categories were determined based on National Comprehensive Cancer Network (NCCN) guidelines. Radiologist assessments were then randomly presented to a radiation oncologist who formulated the radiation plan in a blinded fashion. RESULTS Across 28 patients (median age, 62 years [range, 31-78], T-category classification was significantly different on PET/CT compared to MRI and CT (p = 0.037 and 0.031, respectively). PET/CT staged a higher proportion of patients with T1/T2 disease (16/28, 57%) compared to MRI (11/28, 39%) and CT (10/28, 36%). MRI staged a higher proportion of patients with T3/T4 disease (14/28, 50%) compared to CT (12/28, 43%) and PET/CT (11/28, 39%). However, there was no significant difference between the three imaging modalities in terms of either N-category, AJCC staging, or NCCN TNM group classification, or in treatment planning. CONCLUSION Our exploratory study showed that MRI demonstrated a higher proportion of T3/T4 tumors, while PET/CT demonstrated more T1/T2 tumors; however, MRI, CT, and PET/CT did not show any significant differences in AJCC and TNM group categories, nor was there any significant difference in treatment doses between them when assessed independently by an experienced radiation oncologist.

Abstract
INTRODUCTION The Lower Anogenital Squamous Terminology (LAST) Project recommended unified classification for HPV-associated squamous lesions of the lower anogenital tract, using a 2-tiered nomenclature in 2013. Adherence to the new nomenclature worldwide is unknown. This study aims to assess the trend of the use of the two-tiered High Squamous Intraepithelial Lesion and Low Squamous Intraepithelial Lesion (HSIL/LSIL) as opposed to the traditional three-tiered Anal Intraepithelial Neoplasia (AIN I/II/III) classification as suggested by the LAST Project. METHODS A literature search on full-text English language studies of premalignant anal lesion was performed on PubMed from 2002-2022. The studies were categorized by continent, and the prevalence of HSIL/LSIL classification vs AIN I/II/III was calculated. RESULTS 546 studies and 251 studies were identified using the AIN I/II/II and the HSIL/LSIL classification respectively. Global trend suggested a statistically significant downward trend in the use of the two-tiered nomenclature system in publications globally. Regional trend including North America, Europe, and other (Asia and Latin America) showed variance in adoption of the two-tiered nomenclature system. CONCLUSION Despite multidisciplinary collaborative effort, adherence to the recommendations to use the two-tiered system for HPV-associated premalignant anal lesions continues to be suboptimal. Further efforts are needed to identify the cause of poor adherence to be able to create strategies that reinforces unification of terminology and integration of LAST the recommendations.

Abstract
Purpose: Transgender and gender diverse (TGD) people assigned female at birth (AFAB) face numerous barriers to preventive care, including for cervical cancer screening. At-home human papillomavirus (HPV) testing may expand access to cervical cancer screening for TGD people AFAB. This study assessed the perceptions of TGD individuals AFAB who self-collected cervicovaginal and anal samples. Methods: We recruited TGD individuals AFAB to collect cervicovaginal and anal specimens at home using self-sampling for HPV testing, and individuals reported their perceptions of self-sampling. Associations between demographic and health characteristics and each of comfort of use, ease of use, and willingness to use self-sampling were estimated using robust Poisson regression. Results: Of 137 consenting participants, 101 completed the sample collection and the surveys. The majority of participants reported that the cervicovaginal self-swab was not uncomfortable (68.3%) and not difficult to use (86.1%), and nearly all (96.0%) were willing to use the swab in the future. Fewer participants found the anal swab to not be uncomfortable (47.5%), but most participants still found the anal swab to not be difficult to use (70.2%) and were willing to use the swab in the future (89.1%). Participants were more willing to use either swab if they had not seen a medical professional in the past year. Conclusions: TGD individuals AFAB were willing to use and preferred self-sampling methods for cervicovaginal and anal HPV testing. Developing clinically approved self-sampling options for HPV testing could expand access to cancer screening for TGD populations.

Abstract
INTRODUCTION Anal cancer, a rare malignancy accounting for 2.5-3.0% of gastrointestinal cancers, primarily manifests as squamous cell carcinoma associated with HPV. Recent years have witnessed significant advancements in managing squamous cell carcinoma of the anus (SCCA), particularly with the introduction of immune checkpoint inhibitors (ICIs) and randomized data on front-line chemotherapy. AREAS COVERED This review discusses the current standard treatments for both early and advanced SCCA, based on published data. The authors then describe the new approaches, focusing on ICI combinations, targeted agents, T-cell adoptive therapy, and HPV-therapeutic vaccines. EXPERT OPINION The current standard treatment for SCCA includes front-line carboplatin and paclitaxel, with pembrolizumab and nivolumab as later-line options. While modified DCF has shown promise in single-arm studies, its role as a front-line therapy requires confirmation through randomized data. We eagerly anticipate the results of phase 3 trials investigating the front-line chemo-immunotherapy for metastatic SCCA and ICI consolidation following chemoradiation for early-stage SCCA. Novel approaches like T-cell adoptive therapy, HPV-therapeutic vaccines, and bifunctional antibodies combined with HPV vaccines are in early-stage trials for HPV-mediated tumors, including HPV-positive SCCA. These approaches targeting HPV epitopes may eventually gain tumor-agnostic approval, although their role in SCCA may take time to establish.

Abstract
BACKGROUND Targeted screening programs for patients at high risk for anal squamous-cell carcinoma have been proposed; however, the evidence in support of screening remains unclear. OBJECTIVE This study aimed to determine whether screening high-risk patients (predominantly those living with HIV) detected squamous-cell carcinoma at an earlier stage compared to the routine practice of not screening. DESIGN This is a cohort study. SETTINGS This study was conducted at a quaternary care center in Canada. PATIENTS Included patients were at least 18 years old with a pathologic diagnosis of invasive anal squamous-cell carcinoma between 2002 and 2022. INTERVENTIONS Patients diagnosed through a high-risk screening program were compared to those who did not undergo screening. MAIN OUTCOME MEASURES The primary outcome was clinical stage at presentation, categorized as T1N0M0 vs other. Secondary outcomes included treatments received, treatment failure, and overall survival. RESULTS A total of 612 patients with anal squamous-cell carcinoma were included, with 26 of those patients diagnosed through a screening program. Patients with screen-detected cancers had greater odds of presenting with T1N0M0 tumors compared to unscreened patients (18 [69.2%] vs 84 [14.3%]; adjusted OR 9.95; 95% CI, 3.95-25.08). A propensity score-matched sensitivity analysis found similar results (OR 11.13; 95% CI, 4.67-26.52). Screened patients had greater odds of treatment with wide local excision alone, as opposed to any combination of chemotherapy, radiation therapy, and surgery (3 [12.5%] vs 18 [3.2%]; OR 4.38; 95% CI, 1.20-16.04). There were no statistically significant differences in treatment failure or overall survival between groups. LIMITATIONS The small number of screened patients limits the power of the analysis. CONCLUSIONS Screening for anal squamous-cell carcinoma among high-risk populations detects cancers at an earlier stage. Patients with screen-detected cancers also had a greater likelihood of being candidates for wide local excision alone, which may have spared them the morbidity associated with chemoradiotherapy or abdominoperineal resection.

CNCERES DE ANO EN PACIENTES PREVIAMENTE DETECTADOS POR CRIBADO VERSUS NO DETECTADOS ESTADIO DEL TUMOR Y RESULTADOS DEL TRATAMIENTO ANTECEDENTES:Se han propuesto programas de cribado dirigidos a pacientes con alto riesgo de carcinoma anal de células escamosas; sin embargo, la evidencia a favor de la detección sigue sin estar clara.OBJETIVO:Este estudio tuvo como objetivo determinar si el cribado de pacientes de alto riesgo (predominantemente aquellos que viven con el VIH) detectó el carcinoma de células escamosas en una etapa más temprana en comparación con la práctica habitual de no cribado.DISEÑO:Este es un estudio de cohortes.CONFIGURACIÓN:Este estudio se realizó en un centro de atención cuaternaria en Canadá.PACIENTES:Los pacientes incluidos tenían al menos 18 años con un diagnóstico patológico de carcinoma de células escamosas anal invasivo entre 2002 y 2022.INTERVENCIONES:Los pacientes diagnosticados mediante un programa de cribado de alto riesgo se compararon con aquellos que no se sometieron a cribado.PRINCIPALES MEDIDAS DE RESULTADO:El resultado primario fue el estadio clínico en la presentación, categorizado como T1N0M0 versus otro. Los resultados secundarios incluyeron los tratamientos recibidos, el fracaso del tratamiento y la supervivencia general.RESULTADOS:Se incluyeron un total de 612 pacientes con carcinoma anal de células escamosas, con 26 de esos pacientes diagnosticados a través de un programa de cribado. Los pacientes con cánceres detectados mediante cribado tenían mayores probabilidades de presentar tumores T1N0M0 en comparación con los pacientes no cribados (18 [69.2%] frente a 84 [14.3%]; razón de probabilidad ajustada 9.95; intervalo de confianza del 95 % 3.95 -25.08). Un análisis de sensibilidad emparejado por puntaje de propensión encontró resultados similares (odds ratio 11.13; intervalo de confianza del 95% 4.67 -26.52; p < 0.001). Los pacientes examinados tenían mayores probabilidades de recibir tratamiento con escisión local amplia sola, en comparación con cualquier combinación de quimioterapia, radiación y cirugía (3 [12.5%] frente a 18 [3.2%]; razón de probabilidad 4.38; intervalo de confianza del 95 % 1.20 -16.04). No hubo diferencias estadísticamente significativas en el fracaso del tratamiento o la supervivencia global entre los grupos.LIMITACIONES:El pequeño número de pacientes evaluados limita el poder del análisis.CONCLUSIONES:La detección del carcinoma anal de células escamosas entre las poblaciones de alto riesgo detecta los cánceres en una etapa más temprana. Los pacientes con cánceres detectados mediante cribado también tenían una mayor probabilidad de ser candidatos para una escisión local amplia sola, lo que puede haberles evitado la morbilidad asociada con la quimiorradioterapia o la resección abdominoperineal.

[PMID: 38132209 PMCID: PMC10743290 DOI: 10.3390/diagnostics13243625] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/20/2023] [Revised: 11/14/2023] [Accepted: 11/25/2023] [Indexed: 12/23/2023] Open
Abstract
The surge in the implementation of artificial intelligence (AI) in recent years has permeated many aspects of our life, and health care is no exception. Whereas this technology can offer clear benefits, some of the problems associated with its use have also been recognised and brought into question, for example, its environmental impact. In a similar fashion, health care also has a significant environmental impact, and it requires a considerable source of greenhouse gases. Whereas efforts are being made to reduce the footprint of AI tools, here, we were specifically interested in how employing AI tools in gastroenterology departments, and in particular in conjunction with capsule endoscopy, can reduce the carbon footprint associated with digestive health care while offering improvements, particularly in terms of diagnostic accuracy. We address the different ways that leveraging AI applications can reduce the carbon footprint associated with all types of capsule endoscopy examinations. Moreover, we contemplate how the incorporation of other technologies, such as blockchain technology, into digestive health care can help ensure the sustainability of this clinical speciality and by extension, health care in general.

Abstract
The International Papillomavirus Conference was held in Washington DC in April 2023 and encompassed wide ranging basic, clinical and public health research relating to animal and human papillomaviruses. This editorial is a personal reflection, it does not attempt to be comprehensive and reports on some key aspects centred on the prospects for immune interventions in prevention and treatment of HPV infections and early precancers with a focus on cervical neoplasia. There is optimism for the future impact of immunotherapy in treating early HPV associated disease. This will depend on developing an appropriate design of vaccines and delivery vehicles which then need to be properly tested in clinical trials that are able to measure a useful clinical endpoint. Thereafter vaccines (prophylactic or therapeutic) still need global access and sufficient uptake to deliver impact and a key and necessary driver is education.

Abstract
BACKGROUND The rate of anal squamous cell cancer (aSCC) is increasing among women living with HIV. Treatment of precursor high grade squamous intraepithelial lesions (HSIL) may reduce the risk of progression to aSCC. The objective of this study was to examine effects of a dedicated high-resolution anoscopy (HRA) clinic on management of HSIL in women with HIV. METHODS Women living with HIV who underwent anal dysplasia screening at a single institution between 2006 and 2020 were reviewed. Those who underwent screening before (Group A) and after (Group B) the implementation of an HRA program in 2017 were compared. The primary outcome of interest was the successful detection and treatment of HSIL. RESULTS A total of 201 women living with HIV underwent anal dysplasia screening between 2006 and 2020. Seventy-seven patients were found to have abnormal anal cytology requiring further treatment: 43 (55.8%) in Group A and 34 (44.2%) patients in Group B. Of the patients with abnormal anal cytology, 76.7% of patients in Group A received further biopsy and treatment, whereas 79.4% of Group B patients underwent subsequent biopsy and treatment. In propensity score weighting logistic regression analysis, the Group B was 4.6 times as likely to diagnosis HSIL on biopsy compared to Group A (OR = 4.60, 95% CI: 1.15 to 18.38, P = .03). CONCLUSIONS Anal dysplasia is common among women living with HIV. The establishment of a HRA program was associated with increased identification and treatment of HSIL among women living with HIV, which may prevent the progression to aSCC.

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
Anal cancer is a rare disease, but its incidence has been increasing steadily. Primary staging and assessment after chemoradiation therapy are commonly performed using MRI, which is considered to be the preferred imaging modality. CT and PET/CT are useful in evaluating lymph node metastases and distant metastatic disease. Anal squamous-cell carcinoma (ASCC) and rectal adenocarcinoma are typically indistinguishable on MRI, and a biopsy prior to imaging is necessary to accurately stage the tumor and determine the treatment approach. This review discusses the histology, MR technique, diagnosis, staging, and treatment of anal cancer, with a particular focus on the differences in TNM staging between anal and rectal carcinomas. PURPOSE This review discusses the histology, MR technique, diagnosis, staging, and treatment of anal cancer, with a particular focus on the differences in TNM staging between anal squamous-cell carcinoma (ASCC) and rectal adenocarcinoma. METHODS AND MATERIALS To conduct this updated review, a comprehensive literature search was performed using prominent medical databases, including PubMed and Embase. The search was limited to articles published within the last 10 years (2013-2023) to ensure their relevance to the current state of knowledge. INCLUSION CRITERIA (1) articles that provided substantial information on the diagnostic techniques used for ASCC, mainly focusing on imaging, were included; (2) studies reporting on emerging technologies; (3) English-language articles. EXCLUSION CRITERIA articles that did not meet the inclusion criteria, case reports, or articles with insufficient data. The primary outcome of this review is to assess the accuracy and efficacy of different diagnostic modalities, including CT, MRI, and PET, in diagnosing ASCC. The secondary outcomes are as follows: (1) to identify any advancements or innovations in diagnostic techniques for ASCC over the past decade; (2) to highlight the challenges and limitations of the diagnostic process. RESULTS ASCC is a rare disease; however, its incidence has been steadily increasing. Primary staging and assessment after chemoradiation therapy are commonly performed using MRI, which is considered to be the preferred imaging modality. CT and PET/CT are useful in evaluating lymph node metastases and distant metastatic disease. CONCLUSION ASCC and rectal adenocarcinoma are the most common histological subtypes and are typically indistinguishable on MRI; therefore, a biopsy prior to imaging is necessary to stage the tumor accurately and determine the treatment approach.

Abstract
BACKGROUND Although squamous cell carcinoma is the most common malignancy of the anal canal, it rarely affects the rectum. The present study aimed to assess the differences in characteristics, treatments, clinical and pathologic outcomes, and survival between anal and rectal squamous cell carcinoma. METHODS The United States National Cancer Databases (2004-2020) of anal canal and rectal cancer were used for this retrospective cohort analysis. Patients with anal or rectal squamous cell carcinoma were included in the analysis. The study's primary outcome was overall survival, and secondary outcomes were 30-day and 90-day mortality, 30-day readmission, and positive resection margins. RESULTS The present study included 76,830 patients with anal squamous cell carcinoma and 7,908 with rectal squamous cell carcinoma. Patients with anal squamous cell carcinoma presented more often with early clinical stage I and stage II disease (50.4% vs 45.9%, P < .001) and less often with stage IV disease (6.5% vs 15.1%, P < .001). Anal squamous cell carcinomas were more often treated with upfront surgery than were rectal squamous cell carcinomas (37.7% vs 19.7%, P < .001), whereas rectal squamous cell carcinomas were more often treated with chemoradiation therapy alone (68.3% vs 59.8%, P < .001). Anal squamous cell carcinomas were treated more often with local excision (33.4% vs 15.8%, P < .001) than rectal squamous cell carcinoma. Anal squamous cell carcinoma was associated with a higher incidence of positive resection margins (41.9% vs 32.8%, P < .001). The 30-day and 90-day mortality rates were higher after surgery for rectal squamous cell carcinoma than for anal squamous cell carcinoma (1.5% vs 0.4% and 4.1% vs 1.6%, respectively, P < .001). Anal squamous cell carcinoma had longer median overall survival (145.3 vs 90.3 months, P < .001) than rectal squamous cell carcinoma. CONCLUSION Patients with anal squamous cell carcinoma presented more often with early-stage disease and less often with distant metastasis and were more often treated with upfront surgery, mainly local excision. Anal squamous cell carcinoma was associated with lower 30-day and 90-day mortality and longer overall survival than rectal squamous cell carcinoma.

Abstract
The Centers for Disease Control and Prevention sponsored a project conducted by the American College of Obstetricians and Gynecologists to develop educational materials for clinicians on the prevention and early diagnosis of gynecologic cancers. For this final module, focusing on the cancers of the lower anogenital tract (vulva, vagina, and anus), a panel of experts in evidence assessment from the Society for Academic Specialists in General Obstetrics and Gynecology, ASCCP, and the Society of Gynecologic Oncology reviewed relevant literature and current guidelines. Panel members conducted structured literature reviews, which were then reviewed by other panel members. Representatives from stakeholder professional and patient advocacy organizations met virtually in September 2022 to review and provide comment. This article is the executive summary of the review. It covers prevention, early diagnosis, and special considerations of lower anogenital tract cancer. Knowledge gaps are summarized to provide guidance for future research.

[PMID: 36932225 PMCID: PMC10929685 DOI: 10.1007/s00261-023-03863-8] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/09/2023] [Revised: 02/17/2023] [Accepted: 02/20/2023] [Indexed: 03/19/2023]
Abstract
The role and method of image-based staging of anal cancer has evolved with the rapid development of newer imaging modalities and the need to address the rising incidence of this rare cancer. In 2014, the European Society of Medical Oncology mandated pelvic magnetic resonance imaging (MRI) for anal cancer and subsequently other societies such as the National Comprehensive Cancer Network followed suit with similar recommendations. Nevertheless, great variability exists from center to center and even within individual centers. Notably, this is in stark contrast to the imaging of the anatomically nearby rectal cancer. As participating team members for this malignancy, we embarked on a comprehensive literature review of anal cancer imaging to understand the relative merits of these new technologies which developed after computed tomography (CT), e.g., MRI and positron emission tomography/computed tomography (PET/CT). The results of this literature review helped to inform our next stage: questionnaire development regarding the imaging of anal cancer. Next, we distributed the questionnaire to members of the Society of Abdominal Radiology (SAR) Rectal and Anal Disease-Focused Panel, a group of abdominal radiologists with special interest, experience, and expertise in rectal and anal cancer, to provide expert radiologist opinion on the appropriate anal cancer imaging strategy. In our expert opinion survey, experts advocated the use of MRI in general (65% overall and 91-100% for primary staging clinical scenarios) and acknowledged the superiority of PET/CT for nodal assessment (52-56% agreement for using PET/CT in primary staging clinical scenarios compared to 30% for using MRI). We therefore support the use of MRI and PET and suggest further exploration of PET/MRI as an optimal combined evaluation. Our questionnaire responses emphasized the heterogeneity in imaging practice as performed at numerous academic cancer centers across the United States and underscore the need for further reconciliation and establishment of best imaging practice guidelines for optimized patient care in anal cancer.

Abstract
Anal cancer treatment response assessment can be challenging with both magnetic resonance imaging (MRI) and clinical evaluation considered essential. MRI, in particular, has shown to be useful for the assessment of treatment response, the detection of recurrent disease in follow up and surveillance, and the evaluation of possible post-treatment complications as well as complications from the tumor itself. In this review, we focus on the role of imaging, mainly MRI, in anal cancer treatment response assessment. We also describe the treatment complications that can occur, and the imaging findings associated with those complications.

Abstract
People living with human immunodeficiency virus (HIV) are at high risk for anal cancer. Anal cancer screenings are recommended annually for US veterans with HIV. Screenings can identify treatable precursor lesions and prevent cancer development. In a previous study, we found screening rate to be only 15%. Semistructured interviews were conducted with Veterans Affairs (VA) providers who treat veterans living with HIV. Participants described their experiences with anal cancer screenings. Researchers developed a codebook based on Theoretical Domains Framework (TDF) and coded data using thematic analysis to identify barriers to anal cancer screenings. Twenty-three interviews were conducted with VA providers representing 10 regions. Barriers identified corresponded with five targetable TDF domains: Knowledge, Skills, Environmental Context/Resources, Professional Roles/Identities, and Social Influence. Many providers lacked knowledge of screening protocols. Knowledgeable providers often lacked needed resources, including swabs, clinic space, reliable pathology, access to high-resolution anoscopy, or leadership support to implement a screening program. Providers mentioned competing priorities in the care of veterans with HIV infection and lack of skilled/trained personnel to perform the tests. It was often unclear which provider specialty should "own" screening responsibilities. Additional factors included patient discomfort with screening exams. Anal cancer screening protocols are recommended but not widely adopted in VA. There is a critical need to address barriers to anal cancer screenings in veterans. The TDF domains identified align with five intervention domains to target, including education, training, resource/environment, delineation of provider roles, and improved counseling efforts. Targeting these barriers may help improve the uptake of anal cancer screenings within VA.

Abstract
ABSTRACT Many patients are affected by HIV/AIDS, and these conditions are highly prevalent worldwide. Patients with HIV/AIDS can experience debilitating wound infections that often require flap reconstruction and become challenging for surgeons to treat. In the past 5 years, mesenchymal stem cells have been tested and used as regenerative therapy to promote the growth of tissues throughout the body because of their ability to successfully promote cellular mitogenesis. To the authors' knowledge, the use of mesenchymal stem cell grafting following necrosis of a myocutaneous gracilis flap (as part of perineal wound reconstruction) has never been reported in the literature.In addition, the use of mesenchymal stem cells and regenerative medicine combined in the setting of squamous cell carcinoma of the anus with prior radiation (along with comorbid AIDS) has not been previously documented.In this report, the authors outline the case of a 60-year-old patient who had a recipient bed (perineum) complication from prior radiation therapy. Complicating the clinical picture, the patient also developed a Pseudomonal organ space infection of the pelvis leading to the failure of a vertical rectus abdominis myocutaneous flap and myocutaneous gracilis flaps. As a result, the patient underwent serial operative debridements for source control, with the application of mesenchymal stem cells, fetal bovine dermis, porcine urinary bladder xenograft, and other regenerative medicine products, achieving a highly successful clinical outcome. A procedural description for future use and replication of this method is provided.

Abstract
AIM Squamous cell carcinomas of the anus are normally treated with synchronous chemoradiotherapy (CRT). Small, localized anal margin tumours may be adequately treated by local excision (LE) alone. This study aims to investigate the outcomes of patients with anal margin tumours treated with LE alone, reserving the use of CRT for salvage on local recurrence (LR). METHODS Patients with small, localized (stage I/IIA) anal margin tumours treated by LE from October 1999 to September 2018 were identified. The effect of tumour size and resection margin on LR risk was analysed. Outcomes of overall survival and disease-free survival were measured. RESULTS Fifty-five patients with anal margin tumours were identified. Overall 5-year LR, overall survival and disease-free survival rates were 8%, 86% and 82% respectively. Of the seven LRs, five were successfully salvaged with CRT with no further recurrence and two were not fit for CRT. Resection margins in non-fragmented tumours and tumour size did not significantly influence LR risk. CONCLUSIONS Most small, localized anal margin tumours can be adequately treated by LE alone with low LR rates. Most patients who developed LR were salvaged using CRT, with no cancer-related deaths reported.

Abstract
OBJECTIVE Human papillomavirus (HPV)-related squamous intraepithelial lesion (SIL) or malignancy is associated with a significantly increased risk of second-site SIL or malignancy. The primary objective of this study was to determine the feasibility and acceptability of concurrent anal, cervical, and vulvovaginal screening in patients with a history of HPV-related gynecologic high-grade SIL or malignancy. The secondary objective was to assess subjects' knowledge regarding HPV screening and risks. METHODS Women with high-grade cervical, vulvar, or vaginal SIL or malignancy were enrolled during a 1-year pilot period. Subjects with cervical SIL or malignancy underwent vulvar examination and anoscopy. Subjects with vulvovaginal SIL or malignancy underwent Pap test if indicated and anoscopy. Appropriate referrals were made for abnormal findings. Feasibility was assessed by compliance using study acceptance rate, screening procedure adherence, and referral adherence. Acceptability was assessed using a Likert-scaled question after completion of screening procedures. RESULTS One hundred three women with a diagnosis of high-grade vulvovaginal or cervical SIL or carcinoma were approached regarding study enrollment; of these, 74 (71.8%) enrolled. The median score on the HPV knowledge assessment was 8.1 ± 1.6 (max score 10). Seventy-three (98.6%) of 74 patients rated the screening procedures as acceptable (score of 5/5). On examination, 14 (18.9%) subjects had abnormalities noted; 7 (9.5%) were referred for colorectal surgical evaluation, and 6/7 (85.7%) were compliant with their referral appointments. CONCLUSIONS Screening examinations for other HPV-related SILs and malignancies, including Pap tests, vulvovaginal inspection, and anoscopy, are acceptable to patients, with abnormal findings in almost 1 in 5 women.

Abstract
BACKGROUND Screening of anal cancer is rarely available or performed in Brazil. This study analyzes the diagnostic performance of conventional cytology (CC) in the prevention of anal cancer in a coloproctology and gynecology outpatient clinics in a public hospital in Rio de Janeiro, Brazil. METHODS From 2005 to 2017, 1066 conventional cytological samples were collected. We analyze the causes of unsatisfactory samples (11.3%) and compare the cytological diagnoses of 83 samples from persons living with HIV and persons not living with HIV and in specific situations, using as the gold standard high-resolution anoscopy or histopathology in cases biopsied within 6 months after cytology. RESULTS The sensitivity of cytology with diagnosis of ASC-US for detection of anal intraepithelial neoplasia of any grade was 85%, specificity was 41%, positive and negative predictive values were 64% and 75%, respectively, and positive and negative likelihood ratios were 1.46 and 0.35, respectively. CONCLUSION Conventional cytology available in resource-limited settings is a simple, noninvasive, low-cost method that proved feasible for outpatient screening of precursor lesions of the anal canal.

Abstract
Effective and consistent antiretroviral therapy has enabled people with human immunodeficiency virus (HIV) (PWH) to survive longer than previously encountered earlier in the epidemic. Consequently, PWH are subject to the struggles and clinical conditions typically associated with aging. However, the aging process in PWH is not the same as for those who do not have HIV. There is a complex interplay of molecular, microbiologic, and pharmacologic factors that leads to accelerated aging in PWH; this leads to increased risk for certain age-related comorbidities requiring greater vigilance and interventions in routine care.

Abstract
PURPOSE Squamous cell carcinoma of the anus (SCCA) incidence and mortality rates are rising in the United States. Understanding state-level incidence and mortality patterns and associations with smoking and AIDS prevalence (key risk factors) could help unravel disparities and provide etiologic clues. METHODS Using the US Cancer Statistics and the National Center for Health Statistics data sets, we estimated state-level SCCA incidence and mortality rates. Rate ratios (RRs) were calculated to compare incidence and mortality in 2014-2018 versus 2001-2005. The correlations between SCCA incidence with current smoking (from the Behavioral Risk Factor Surveillance System) and AIDS (from the HIV Surveillance system) prevalence were evaluated using Spearman's rank correlation coefficient. RESULTS Nationally, SCCA incidence and mortality rates (per 100,000) increased among men (incidence, 2.29-3.36, mortality, 0.46-0.74) and women (incidence, 3.88-6.30, mortality, 0.65-1.02) age ≥ 50 years, but decreased among men age < 50 years and were stable among similar-aged women. In state-level analysis, a marked increase in incidence (≥ 1.5-fold for men and ≥ two-fold for women) and mortality (≥ two-fold) for persons age ≥ 50 years was largely concentrated in the Midwestern and Southeastern states. State-level SCCA incidence rates in recent years (2014-2018) among men were correlated (r = 0.47, P < .001) with state-level AIDS prevalence patterns. For women, a correlation was observed between state-level SCCA incidence rates and smoking prevalence (r = 0.49, P < .001). CONCLUSION During 2001-2005 to 2014-2018, SCCA incidence and mortality nearly doubled among men and women age ≥ 50 years living in Midwest and Southeast. State variation in AIDS and smoking patterns may explain variation in SCCA incidence. Improved and targeted prevention is needed to combat the rise in SCCA incidence and mitigate magnifying geographic disparities.

Abstract
BACKGROUND Anal cancer is a human papillomavirus-related cancer. Screening with high-resolution anoscopy (HRA) and subsequent therapeutic intervention are increasingly recognized as the standard procedure for anal cancer. Generally, lesions suspected as being high-grade squamous intraepithelial lesions are biopsied and treated if they are grade 2 or 3 anal intraepithelial neoplasia (AIN). According to several studies, electrocautery ablation for grade 2 or 3 AIN is highly effective. However, relapse within and outside the targeted areas after the intervention is a clinical problem. In Japan, electrocautery ablation is not available at most facilities. Therefore, this study aims to investigate the efficacy and safety of electrocautery ablation. METHODS This single-arm, open-label, pilot intervention study will investigate the efficacy and safety of electrocautery ablative therapy using high-frequency medical devices. Patients diagnosed with grade 2 or 3 AIN will be included and will receive ablation treatment. Then, they will be followed up at 3 and 6 months after the procedure for HRA-guided sextant biopsy. To reduce the possibility of missed lesions before and after the intervention, we will perform HRA-guided sextant biopsy routinely. In this study, a sextant biopsy is defined as at least 6 biopsies in all directions, regardless of abnormal findings under HRA. The primary outcome is the recurrence rate at 6 months, and the secondary outcomes are the adverse event and recurrence rates at 3 months. CONCLUSION This pilot study will provide data on the effectiveness and safety of electrocautery ablation as a treatment for grade 2 or 3 AIN.

Anal Cancer in High-Risk Women: The Lost Tribe. Cancers (Basel) 2022; 15:cancers15010060.

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.

Abstract
AIM Evidence-based medicine is essential for clinical practice. Clinical practice guidelines (CPGs) and consensus statements (CSs) ought to follow a consistent methodology to underpin high-quality healthcare. We systematically analysed the quality and reporting of colorectal (CRC) and anal cancer CPGs and CSs. METHODS Embase, MEDLINE, Scopus, Web of Science, the Cochrane Database of Systematic Reviews and online sources (59 professional society websites and eight guideline databases) were systematically searched following prospective registration (PROSPERO no. CRD42021286146) by two reviewers independently, without language restrictions. CPGs and CSs about CRC and anal cancer treatment were included from January 2018 to November 2021 and were assessed using the AGREE II tool (per cent of maximum score) and the RIGHT tool (per cent of total 35 items) for quality and reporting respectively. RESULTS The median overall quality and reporting of the 59 guidelines analysed were 55.0% (interquartile range 47.0-62.0) and 58% (interquartile range 50.0-67.9), respectively, with a proportion scoring less than half (<50%) for quality (20/59, 33.9%) and reporting (15/59, 25.4%). Guidance reported that following AGREE II methodology scored better on average than that without (AGREE II 77.7% vs. 47.6%, P = 0.001; RIGHT 50.0% vs. 33.9%, P = 0.001). Guidelines based on systematic reviews had better quality and reporting on average than those based on consensus (AGREE II 56.5% vs. 46.6%, P = 0.001; RIGHT 36.9% vs. 35.4%, P = 0.019). CONCLUSION The quality and reporting of colorectal and anal cancer treatment CPGs and CSs were poor. Despite AGREE II and RIGHT inherent methodological limitations, few high-quality guidelines were found. Despite wide variability in scoring different domains, they merit urgent improvement in all areas. It has also been demonstrated that CPGs and CSs should be underpinned by systematic reviews collecting the best available clinical research findings.

Abstract
PURPOSE Squamous cell carcinoma of the anus (SCCA) suffers a constant increase each year in the last decades. Recent studies suggested the possibility of local excision (LE) as an option for early-stage SCAC patients. This systematic review aims to summarize the available evidence on the comparison of LE vs. chemoradiotherapy (CRT) in the treatment of early SCCA patients. METHODS We conducted a literature review including MEDLINE/PubMed, EMBASE, SCOPUS, clinicaltrials.gov, and the Cochrane Database of Systematic Reviews through June 2022. MOOSE guidelines were followed. We used the methodological index for non-randomized studies (MINORS) tool to assess quality. Data on survival and procedure-associated costs were extracted. RESULTS Four retrospective studies including 3323 patients were included. They were all comparative retrospective cohort studies (three were registry-based studies, either NCDB or SEER) with a MINORS score of 16-19 points. Overall survival (OS) was comparable between LE and CRT patients in three studies, with a 5-year OS of 85.3-100% in LE patients and 85-91.6% in CRT patients. One study investigated cancer-specific survival (CSS) and reported similar 5-year CSS in LE (98%) and CRT patients (96%). One investigated progression-free survival (PFS) and did not report any statistically significant difference in 5-year PFS between LE (91%) and CRT patients (83%). Only one study considered the mean costs associated with the two approaches (29,210 USD with LE and 46,350 USD with CRT). CONCLUSIONS LE may potentially be considered a valid alternative to CRT for patients with early-stage SCAA. Results of prospective randomized long-term trials comparing LE with CRT are warranted to draw definitive conclusions and consider LE as a true cost-effective strategy for T1N0 SCCA with similar oncologic results offered by CRT, which-to date-remains the "gold standard."

Abstract
OBJECTIVE Rectal cancer is common in developed countries, though incidence varies globally. We assessed time trends in incidence, relative survival and mortality in Denmark. METHODS Rectal cancer cases ( N = 50 461) diagnosed in 1978-2018 were identified in the Danish Cancer Registry. We calculated age-standardized incidence rates, overall and according to sex and age. Average annual percentage changes (AAPC) were estimated using Poisson regression. We estimated 5-year relative survival and evaluated the effect of age, calendar year of diagnosis, sex and stage of disease on mortality using the Cox proportional hazards model. RESULTS The incidence of rectal cancer tended to decrease in all age groups and both sexes during 1978-1997, but increased since 1998, more in men (AAPC = 2.05%; 95% CI,1.80; 2.31) than in women (AAPC = 0.99%; 95% CI,0.68; 1.30). It increased in men until 79 years and in women up to 59 years. Mortality decreased over time when adjusting for age, stage and sex. Overall, men had the highest 5-year mortality after adjusting for age, calendar period and stage. Five-year relative survival improved (1978-2018) for all stages. Initially, the overall 5-year relative survival tended to be better for women, but in recent years, it has been similar in both sexes. CONCLUSION Incidence of rectal cancer increased in the last two decades, most markedly in women 59 years and younger. Mortality decreased when adjusting for age and stage. Relative survival improved over time more for men than for women, so in recent years, it has been virtually identical in men and women.

Abstract
There are substantial disparities in cancer screening for sexual minorities and gender non-conforming patients. In additional to patients having trauma due to negative experiences with the healthcare system, disparities may be heightened due to heteronormative and cisnormative design of screening programs and electronic medical record systems. Furthermore, there are morphologic challenges specific to certain specimen types from the LGBT + population, such as anal cytology samples, cervical cytology from transgender men taking testosterone, and neovaginal cytology samples. Men who have sex with men are at increased risk for anal cancer compared with the general population. While early detection of anal dysplasia decreases the risk of invasive carcinoma, screening programs are not widespread. Cervical cancer screening may be psychologically and physically challenging for transgender men and non-binary patients. The use of exogenous testosterone therapy causes atrophic changes in cervical cytology samples which mimic high-grade dysplasia. The rate of unsatisfactory samples are also increased in this population. Although HPV driven cancers have been reported in patients with neovaginas, there are currently no guidelines about appropriate screening for transgender women and intersex patients who have neovaginas. Cytopathologists can optimize the health of LGBT + patients in many ways including advocating for inclusive screening guidelines, validating self-collection for HPV and cytology samples, updating requisition forms to better capture the spectrum of gender expression, and recognizing the morphologic changes in cytology samples due to exogenous hormone use.

Abstract
BACKGROUND Care cascades can inform providers about differences in engagement and retention in care between patient populations thereby improving participation by targeting interventions more effectively. The objective of this study was to assess the uptake and retention of participants along the anal cancer screening algorithm within a single HIV clinic. METHODS Retrospective procedural and demographic data were collected within a Ryan White HIV/AIDS Program clinic from 18 December 2017 to 29 May 2021. A care cascade was constructed among eligible participants who engaged and were retained in the anal cancer screening algorithm. Engagement was defined as having at least one anal Pap smear. Retention was defined as having a follow-up anal Pap smear, and/or high resolution anoscopy, as indicated. Risk ratios (RR) were calculated to reveal factors associated with initiation and retention in screening. RESULTS Of 821 eligible participants, 312 (38%) engaged in screening and 205 (66%) were retained in care. Anoreceptive intercourse was positively associated with engagement (RR 2.81, 95% confidence interval [CI] 2.05-3.90, p<0.001), whereas male gender was negatively associated (RR 0.26, 95% CI 0.20-0.33, p<0.001). Abnormal cytology results on Pap smear were associated with retention (RR 1.39, 95% CI 1.03-1.86, p=0.03). CONCLUSIONS Overall engagement in anal cancer screening is low within our clinic, particularly among men, but retention in the screening program is notably better, especially among those with abnormal cytology. Target populations have been identified to increase awareness, and qualitative studies are underway to understand perceptions and barriers to engagement in anal cancer screening.

Abstract
Anal squamous cell carcinoma (SCC) is a human papillomavirus (HPV)-mediated malignancy with increasing incidence. HIV infection is a significant risk factor for anal SCC, however it is unknown if HIV infection alters anal lesion progression and HPV strain profile. This study aims to determine whether HIV co-infection is associated with progression of HPV-mediated anal lesions and on their HPV strain diversity. This is a retrospective cohort study of adults with anal squamous intraepithelial lesion (SIL) who presented for anorectal sampling between 2010-2019. Using the full cohort, we performed clinicopathologic epidemiologic analysis of HIV co-infection on lesion progression. Using a subset of patients, we conducted molecular analysis of HPV strain diversity as related to HIV status and progression. Our cohort included 2203 individuals, of which 940 (43%) were HIV+. HIV+ status was associated with faster progression at all levels of dysplasia. Our molecular cohort included 329 adults, of which 190 (57.8%) were HIV+. HIV+ status was associated with higher HPV strain diversity (median: 7 [5-9] vs. median: 4 [4-6], P<0.001). Latent class analysis identified specific HPV strain signatures associated with progression. We demonstrate that HIV+ individuals had faster rates of anal SIL progression and that almost all HPV strains were more prevalent in anal samples from HIV+ adults. Our results imply that HIV+ adults with anal SIL should undergo more frequent screening and obtain HPV genotyping at initial presentation, as it shows value as a biomarker of lesion progression.

Abstract
BACKGROUND The incidence of anal cancer is substantially higher among persons living with the human immunodeficiency virus (HIV) than in the general population. Similar to cervical cancer, anal cancer is preceded by high-grade squamous intraepithelial lesions (HSILs). Treatment for cervical HSIL reduces progression to cervical cancer; however, data from prospective studies of treatment for anal HSIL to prevent anal cancer are lacking. METHODS We conducted a phase 3 trial at 25 U.S. sites. Persons living with HIV who were 35 years of age or older and who had biopsy-proven anal HSIL were randomly assigned, in a 1:1 ratio, to receive either HSIL treatment or active monitoring without treatment. Treatment included office-based ablative procedures, ablation or excision under anesthesia, or the administration of topical fluorouracil or imiquimod. The primary outcome was progression to anal cancer in a time-to-event analysis. Participants in the treatment group were treated until HSIL was completely resolved. All the participants underwent high-resolution anoscopy at least every 6 months; biopsy was also performed for suspected ongoing HSIL in the treatment group, annually in the active-monitoring group, or any time there was concern for cancer. RESULTS Of 4459 participants who underwent randomization, 4446 (99.7%) were included in the analysis of the time to progression to cancer. With a median follow-up of 25.8 months, 9 cases were diagnosed in the treatment group (173 per 100,000 person-years; 95% confidence interval [CI], 90 to 332) and 21 cases in the active-monitoring group (402 per 100,000 person-years; 95% CI, 262 to 616). The rate of progression to anal cancer was lower in the treatment group than in the active-monitoring group by 57% (95% CI, 6 to 80; P = 0.03 by log-rank test). CONCLUSIONS Among participants with biopsy-proven anal HSIL, the risk of anal cancer was significantly lower with treatment for anal HSIL than with active monitoring.

Abstract
BACKGROUND Risk of anal squamous cell carcinoma (anal cancer) is greater among men who have sex with men (MSM) living with human immunodeficiency virus (HIV). We describe the frequency of and factors associated with abnormal anal cytology results in Colombian MSM living with HIV. METHODS This retrospective observational cohort study included MSM ≥18 years old living with HIV screened with anal cytology at Hospital Universitario San Ignacio in Bogotá, Colombia between January 2019 and February 2020. A multivariable log-binomial regression model estimated associations with abnormal anal cytology. RESULTS A total of 211 patients were included. Mean age was 35.6 years. Sixty-eight (32.3%) had an abnormal anal cytology result: ASC-US 33.8% (n = 23); LSIL 60.3% (n = 41); and HSIL 5.9% (n = 4). MSM with an STI diagnosis in the previous 12 months (RR 1.48, [95% CI 1.03-2.12], p = 0.032) or with a CD4+ T cell count <200 (RR 2.08 [95% CI 1.16-3.73], p = 0.014) were significantly more likely to have abnormal anal cytology. CONCLUSIONS These data provide crucial information to guide scale up of anal cancer screening at select centers in Colombia. Our results also suggest STI prevention efforts and improved virological control among MSM living with HIV may have the secondary benefit of reducing the risk of anal cancer.

Abstract
BACKGROUND The current standard of care for anal squamous cell carcinoma (SCC) is concurrent chemoradiation (CRT), which enables tumor eradication while preserving the anal sphincter. Patients with locally advanced tumors, however, may experience complications that preclude treatment before stoma creation. OBJECTIVE To evaluate the reversal rate of pretreatment stomas and the risk factors associated with nonreversal. METHODS This single-institution retrospective cohort study using a prospective database included patients diagnosed with anal SCC from January 2008 to December 2020 who required a stoma before curative CRT. RESULTS In total, 651 patients were identified; 65 required a stoma before chemoradiation due to obstruction (43.1%), rectovaginal fistula (20%), and perianal sepsis (36.9%). The stoma was reversed in nine patients after a mean follow-up of 35.8 months. Risk factors associated with a permanent stoma were perianal sepsis (p = 0.010), interruptions during radiotherapy for more than 7 days (p = 0.010), male sex (p = 0.013), poor performance status (Eastern Cooperative Oncology Group [ECOG] ≥ 2) (p = 0.023), large tumors (p = 0.045), and cisplatin-based chemotherapy (p = 0.047). CONCLUSIONS Pretreatment stomas are unlikely to be reversed, and risk factors for a permanent stoma are perianal sepsis, interruptions during radiotherapy for more than 7 days, male sex, poor performance status (ECOG ≥ 2), large tumors, and cisplatin-based chemotherapy.

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
BACKGROUND Squamous cell carcinoma of the anus (SCCA) is associated with human papillomavirus infection and preceded by high-grade squamous intraepithelial lesions (HSIL). Following successful treatment, the standard of care is to surveille for local recurrence with both anoscopy and digital rectal examination. While high-resolution anoscopy (HRA) has been shown to identify HSIL during the surveillance period, it requires specialized training and resources.1 The burden of these resources may be reduced by conducting surveillance with anal cytology. We studied 2 questions: (1) Can anal cytology identify HSIL in patients after successful treatment of SCCA? (2) Can HSIL be found with anal cytology after completion of chemoradiation for SCCA? METHODS Patient charts were queried for diagnosis of SCCA. Patients were excluded if they were not successfully treated for cure or if patients had not been seen in the surveillance period of 5 years following treatment. Descriptive statistics were elucidated. RESULTS 104 patient charts met inclusion criteria. 81 were surveilled using standard of care, while 23 were followed with standard of care plus anal cytology. 5 patients followed with cytology demonstrated HSIL. 2/5 were found via cytology, 1/5 via HRA, and 2/5 patients via exam under anesthesia and biopsy. DISCUSSION This study demonstrated that HSIL was identified cytologically in the surveillance period. There may be utility in using anal cytology to identify HSIL in patients during this period in lieu of the specialized resources required for HRA. This may allow dysplasia to be treated with excision and fulguration prior to redevelopment of SCCA.

Abstract
OBJECTIVES Anal squamous cell carcinoma (ASCC) is an uncommon cancer that is rapidly increasing in incidence. HIV is a risk factor in the development of ASCC, and it is thought that the rapidly increasing incidence in men is related to increasing numbers of people living with HIV (PLWH). We undertook a population-based study comparing the demographics and incidence of ASCC in patients residing high HIV prevalence areas in England to patients living in average HIV prevalence areas in England. METHODS This is a cross-sectional study following the 'Strengthening the Reporting of Observational Studies in Epidemiology' statement. Demographic data and incidence rates of ASCC within Clinical Commissioning Groups (CCGs) between 2013 and 2018 were extracted from the Cancer Outcomes and Services Dataset. CCGs were then stratified by HIV prevalence from data given by Public Health England, and high HIV prevalence geographical areas were compared with average HIV geographical areas. RESULTS Patients in high HIV areas were more likely to be young and male with higher levels of social deprivation. Incidence rates in men between 2013 and 2017 were higher in high HIV areas than average HIV areas with a rapidly increasing incidence rates in early-stage disease and a 79.1% reduction in incidence of metastatic stage 4 disease.Whereas women in high HIV areas had lower ASCC incidence than the national average and a low incidence of early-stage disease; however, metastatic disease in women had quintupled in incidence in high HIV areas since 2013. CONCLUSIONS Patients presenting with ASCC in high HIV geographical areas have different demographics to patients presenting in average HIV geographical areas. This may be related to screening programmes for PLWH in high HIV areas.

Abstract
AIM Emerging evidence has suggested that metformin may be protective against the development of human-papillomavirus-related cancers. Anal intraepithelial neoplasia (AIN) is highly associated with human papillomavirus infection and a precancerous status of anal cancer. The aim of this study was to investigate the relationship between metformin usage and the development of AIN in a large national sample. METHODOLOGY The IBM MarketScan dataset was used to design a nested case-control study from 2010 to 2017. Patients aged 18-65 years with type 2 diabetes mellitus (DM) were evaluated, and cases of AIN were identified. Four controls were randomly selected in the risk set of each case by using incidence density sampling. The association between metformin usage and AIN was assessed using multivariate logistic regression modelling. RESULTS A total of 258 patients with type 2 DM were diagnosed with AIN during the study interval, and these were matched to 1032 control patients without a diagnosis of AIN. Patients who developed AIN had 38% lower odds of prior metformin use compared to those without a history of AIN (P < 0.01) and this finding remained robust after adjusting for age, sex, human immunodeficiency virus infection and DM complications (P = 0.02). Patients with AIN had 56% lower odds of long-term metformin use compared to control patients (P = 0.01). CONCLUSIONS An AIN diagnosis in patients with DM is associated with 56% lower likelihood of prior metformin use. This relationship suggests that metformin could potentially play a protective role against AIN. Prospective studies in non-diabetic patients are warranted to examine these findings further.

Abstract
Background Anal squamous cell carcinoma (ASCC) is the main subtype of anal cancer and has great heterogeneity in prognosis. We aimed to construct a nomogram for predicting their 1‐, 3‐, and 5‐year overall survival (OS) rates. Methods Patients with ASCC, enrolled between January 1, 2010 and December 31, 2017, were identified from the SEER database. They were divided into a training group and a validation group in a ratio of 7:3. Univariate and multivariate Cox analyses were used to identify the prognostic factors for OS. Then a prognostic nomogram was established and validated by Harrell consistency index (C‐index), area under the curve (AUC) of the receiver operating characteristic (ROC) curves, calibration plots, and decision curve analysis (DCA). Results We identified 761 patients in training group and 326 patients in validation group. Four prognostic factors including age, sex, AJCC stage, and radiotherapy were identified and integrated to construct a prognostic nomogram. The C‐index and AUC values proved the model's effectiveness and calibration plots manifested its excellent discrimination. Furthermore, in comparison to the AJCC stage, the C‐index, AUC, and DCA proved the nomogram to be of good predictive value. Finally, we constructed a risk stratification model for dividing patients into low‐risk, medium‐risk, and high‐risk groups, and there were obvious differences in OS. Conclusions A prognostic nomogram was firstly established for predicting the survival probability of ASCC patients and helping clinicians improve their risk management.

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.
