Radiation after thymoma surgery: does it keep cancer away?

NCT ID NCT04731610

First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This study looks at whether giving radiation therapy after surgery can stop thymoma (a rare chest tumor) from returning in patients with stage II or III disease. About 314 adults aged 18-75 who had the tumor completely removed will be randomly assigned to receive radiation or just be watched. The main goal is to see if radiation improves the time without cancer coming back.
