Precision radiation therapy for early-stage lung cancer in the center of the lung

This study is testing a new type of radiation therapy called online adaptive stereotactic radiotherapy for early-stage lung cancer that is located in the center of the lung. The treatment adjusts in real time during each session using special imaging, which allows doctors to remove safety margins they normally add around the tumor. The goal is to deliver effective radiation while potentially reducing side effects.

Standard radiation therapy adds extra space around tumors to account for patient movement and positioning changes. This trial is testing whether real-time imaging and adjustment during treatment can be so precise that these safety margins are no longer needed, potentially making treatment safer and more effective.
