Radiation after surgery may boost survival in tough lung cancer cases
NCT ID NCT06878274
First seen Jun 27, 2026 · Last updated Aug 14, 2026 · Updated 1 time
Summary
This study looks at whether giving radiation to the chest after surgery and chemo-immunotherapy can help people with stage III non-small cell lung cancer who still have signs of cancer after treatment. About 118 adults will be randomly assigned to receive or not receive radiation. The goal is to see if radiation can delay the cancer from coming back and improve survival, while also checking side effects and quality of life.
