Developing a screening algorithm for anal high-grade lesions in men who have sex with men

Optimizing an Anal High-grade Squamous Intraepithelial Lesion Screening Algorithm for Thai Men Who Have Sex With Men and Transgender Women

Not applicable Interventional Institute of HIV Research and Innovation Foundation, Thailand · NCT05531799

This study is testing a new way to screen for serious anal lesions in men who have sex with men and transgender women to see if it can improve detection and care.

What this trial studies

This study aims to create an optimized screening algorithm for anal high-grade squamous intraepithelial lesions (HSIL) specifically for men who have sex with men (MSM) and transgender women (TGW). Utilizing a Multiphase Optimization Strategy Trial (MOST) design, the researchers will evaluate various intervention components to determine the most effective and efficient screening approach. The implementation of the selected algorithm will be guided by the RE-AIM framework to ensure comprehensive evaluation and uptake in clinical settings. An interrupted time series analysis will compare screening uptake before and after the algorithm's implementation.

Who should consider this trial

Good fit: Ideal candidates include Thai MSM and TGW who are HIV-positive aged 30 years or older or HIV-negative aged 40 years or older.

Not a fit: Patients who are unable to perform study procedures or have anal cancer lesions at enrollment will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could significantly improve the early detection and management of anal HSIL, leading to better health outcomes for MSM and TGW populations.

How similar studies have performed: While similar approaches have been explored, this specific optimization strategy for anal HSIL screening in MSM and TGW populations is novel.
