Oral cancer patients may avoid unnecessary radiation to the neck
NCT ID NCT07528495
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether it is safe to skip radiation to the lymph nodes in the neck after surgery for early-stage oral cancer. About 396 adults aged 18-70 with certain high-risk features will be randomly assigned to receive or not receive this radiation. The goal is to see if skipping it leads to similar cancer control in the neck area, reducing side effects without harming outcomes.
