Clinical Trial Summary

The purpose of this research study is to find ways to screen for anal cancer among gay, bisexual, and other men who have sex with men (MSM) and transgender persons. This study will try to find out if persons will do annual anal cancer screening, what factors are associated with repeated screening, and how this affects a person's decision to have high-resolution anoscopy.

Description:

This is a prospective, randomized, two-arm clinical study to evaluate compliance with annual home-based vs clinic-based DNA screening of anal canal exfoliated cells among Milwaukee HIV+ and HIV- men who have sex with men and transpersons aged ≥25 years. At study entry, persons randomized to arm 1 will receive a home-based collection kit in the mail at 0 and 12 months and those in arm 2 will attend a clinic where a clinician will collect the exfoliated cell specimen at 0 and 12 months. Then, persons will receive HRA-directed biopsy to assess precancerous lesions by study arm. We hypothesize that a majority of persons will comply with annual screening with increased compliance among persons in the home-based arm vs clinic-based arm. The proposed research could indicate that annual HPV DNA screening and subsequent HRA are acceptable to MSM and transpersons; thus, we will determine how high-risk persons are identified for HRA in light of limited HRA resources. The duration of each participant's activities is expected to be 12 months. The study is expected have participant activity from 2019 to 2023.
