    Thoracic radiation therapy is a key treatment for locally advanced non-small cell lung cancer, but it poses significant long-term cardiac and immune system toxicities.

  • 2

    Higher radiation doses to the heart correlate with increased mortality, indicating that cardiac toxicity adversely affects survival outcomes in NSCLC patients.

  • 3

    Specific cardiac substructures, such as the sinoatrial node and coronary vessels, have been identified as critical areas linked to worse survival following thoracic RT.

  • 4

    Thoracic RT may induce lymphopenia and compromise immune surveillance, potentially reducing the effectiveness of concurrent immunotherapy.

  • 5

    Future research should focus on preserving immune integrity and integrating immune-sparing techniques into radiation planning for NSCLC.
