Self-Sampling to Optimize Anal Lesion Outcomes (SOLO) Pilot

Medical College of Wisconsin·interventional·Posted Jul 25, 2025·Updated Jan 27, 2026

In Brief

A clinical study evaluating Inserting a swab 5 cm into the anus during self-sampling and Self-sampling with a swab by inserting the swab 3 cm into the anus. for Squamous Cell Carcinoma of the Anus. Completed, enrolled 50 participants across 1 site.

Detailed Summary

The investigators will test the cytological performance of a nylon-flocked swab at two insertion depths in the anus, 3 cm and 5 cm, to determine which insertion depth is better at collecting cells from the squamocolumnar junction (SCJ), an anatomic site that is particularly vulnerable to carcinogenic transformation. The investigators hypothesize that the 5 cm insertion will result in a higher quality specimen with cells from the SCJ. However, the deeper swab insertion may affect end user acceptability without increasing adequacy or quality.
