Summary

This study tested a newer, more precise type of radiation called pencil beam proton therapy, given together with standard chemotherapy, for people with anal cancer. The goal was to see if this approach is practical and might cause fewer side effects than standard radiation. Twenty-five participants were enrolled, and researchers measured how well the treatment could be delivered and tracked any severe skin reactions.
