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.

Introduction: High-resolution anoscopy (HRA) to prevent anal cancer is complex and screening capacity is limited. Previously, we showed that DNA methylation analysis of anal high-grade squamous intraepithelial lesions (HSIL) biopsies can distinguish between HSIL with an increased cancer risk, and HSIL with a low cancer risk, in which treatment may be safely withheld. Here, we assessed the performance of methylation analysis in anal swabs to identify patients with underlying HSIL with an increased cancer risk.

Human papillomavirus (HPV), the predominant viral infection affecting the anogenital tract, is closely linked to the development of intraepithelial neoplasia and malignancies in the cervix and other anal regions. Currently, 15 high-risk HPVs (HR-HPVs) and 3 potential HR-HPV types have been recognized as contributors to cervical cancer. Consequently, it is imperative to conduct HR-HPV screening using suitable tests in order to identify precancerous lesions and prevent the development of cancer.

While cancer is a leading cause of death worldwide, significant disparities exist in care access in low‑ and middle‑income countries (LMICs). In Liberia, screening and treatment for anal cancers remain limited, and are exacerbated among vulnerable groups, including men who have sex with men (MSM). Screen‑triage‑treat models for cancerous lesions have been successful in reducing cervical cancer mortality, but the feasibility of this approach has not been studied for anal cancers in a low‑resource context.

Anal Squamous Cell Carcinoma (SCCA) is a rare Human Papillomavirus type 16 (HPV16)-associated carcinoma whose pathogenesis is still poorly understood. Recent studies based on biopsy and Next Generation Sequencing (NGS) approaches have linked the viral episomal status to aggressive SCCA phenotypes, suggesting a potential role of the 16E5 oncoprotein in tumor development. Our previous findings indicated that 16E5 induces Fibroblast Growth Factor Receptor 2 (FGFR2) isoform switching, aberrant mesenchymal FGFR2c expression, Epithelial Mesenchymal Transition (EMT), and cell invasion in various in vitro human keratinocyte models, as well as in the in vivo context of cervical Low-grade Squamous Intraepithelial Lesions (LSILs).

Objective: High-resolution anoscopy (HRA) with ablation of high-grade squamous intraepithelial lesions (HSIL) can prevent the development of anal cancer in people with HIV (PWH). The authors sought to characterize factors associated with successful HSIL resolution or local or metachronous recurrence.
Methods: The authors conducted a retrospective study of 62 PWH who underwent HRAs from December 1, 2017, to July 1, 2022.
