    Abstract Background: The incidence of anal cancer has increased over at least the past decade, with estimates of a continued increase in the coming years. Women are more commonly affected than men in the general population; separate high-risk populations have also been identified. While the pathophysiology of anal cancer is thought to be similar to its cervical counterpart, well-defined and standardized screening guidelines have not been established as is seen in cervical cancer prevention. Nonetheless, multiple screening modalities have been examined and are components of proposed institutional and societal screening programs.
    Summary: Anal cytology is one modality that is a mainstay of many suggested screening guidelines. Interpretation and reporting follow current criteria for cervical/vaginal cytology per the Bethesda System, with site-specific alterations and changes in adequacy criteria to better accommodate some of the confounding factors encountered in anal cytology. While there are some limitations, such as a tendency to underestimate the degree of dysplasia and variable interobserver concordance rates, anal cytology, especially liquid-based preparations, overall performs well in detecting anal abnormalities and acts as an adequate screening tool. Importantly, most anal squamous dysplasias and cancers are also associated with human papillomavirus (HPV) infection, raising the possibility of HPV testing or genotyping as a component of screening and/or follow-up. Studies have also shown the efficacy of HPV vaccination in preventing anal lesions. Digital anorectal exam as well as anoscopy, particularly high-resolution anoscopy, are also often components of screening and follow-up. Management guidelines such as those put forth by the American Society for Colposcopy and Cervical Pathology (ASCCP) for cervical cancer are also not established for anal cancer. However, studies such as the Anal Cancer HSIL Outcomes Research (ANCHOR) trial have made significant strides in demonstrating successes in follow-up and treatment of anal lesions, findings that are crucial for establishing prevention and management guidelines going forward.

    Abstract Background: Anal cytology (AC) is accepted as a practical screening modality for anal cancer. However, studies suggest that AC and anal biopsy dysplasia correlation is less robust than in cervicovaginal specimens. The current study goals were to look at our institutional experience in a subset of ACs and correlate with surgical pathology (SP), as well as evaluate their Human Papillomavirus (HPV) status.
    Methods: 377 ACs from 169 patients (151 males and 18 females) from 2008 to 2017 were included. HPV genotyping (n = 47) and SP within one year of AC (n = 58) were reviewed.
    Results: AC/SP was discrepant in 22 cases (37.9%), with a tendency towards AC underestimating the degree of dysplasia. Specifically, any abnormality on AC was 93.8% sensitive for detecting high-grade dysplasia (HGD). However, when requiring a high-grade AC diagnosis, the sensitivity decreases to 12.5%. "Other high-risk HPV" was the most common genotype (57.4%). When considered with all AC with a high-grade diagnosis, co-testing with HPV improved the sensitivity for HGD to 56.3%. Sensitivity improved further to 87.5% when only considering cases with both AC and HPV testing, and were high-risk HPV positive. Furthermore, following review and consensus diagnosis, 8 cases changed from "Discrepant" to "Agreed", reducing the discrepancy rate to 24.1%. Remaining discrepancies were explained by sampling error.
    Conclusion: Given the enhanced sensitivity of AC and HPV testing together, and sampling error seen with AC leading to underestimating dysplasia, we recommend AC and HPV co-testing, as well as describing confounding factors in AC reports and obtaining consensus opinion in equivocal cases.

    Abstract Objectives: Partnerships between low- to middle-income countries (LMICs) and high-income countries (HICs) is one strategy to mitigate observed health disparities. Cambodia's Angkor Hospital for Children (AHC), an LMIC institution, faces shortages in health care resources, including pathology services. A partnership was created with Children's Wisconsin (CW), an HIC hospital, including provision of pathology services. We describe our established pathology workflow, examine cases seen in AHC patients, and evaluate the impact of CW's interpretations.
    Methods: AHC provides clinical history and impression and ships samples to CW, which processes the samples, and pathologists provide interpretations, sending reports electronically to AHC. For analysis, final diagnoses were considered "concordant," "refined," or "discordant" based on agreement with the clinical impression. Cases were also classified as "did not change management" or "changed management" based on how CW interpretation affected clinical management.
    Results: We included 347 specimens (177 malignant, 146 benign, 24 insufficient for diagnosis). Of these cases, 31% were discordant and 44% of cases with clinical follow-up had a change in management with CW interpretation.
    Conclusions: Inclusion of pathology services in LMIC-HIC partnerships is crucial for resolving health disparities between the institutions involved. The described partnership and established pathology workflow can be adapted to the needs and resources of many institutions.
