Sparing Cardiac Substructures with Optimized Volumetric Modulated Arc Therapy and Intensity-Modulated Proton Therapy in Thoracic Radiation for Locally Advanced Non-Small Cell Lung Cancer

ConclusionsVMAT is now widely available, and high-quality VMAT plans that incorporate the cardiac substructures into the optimization process can provide overall improvements in doses to OARs and in particular substantial sparing of critical cardiac structures. IMPT provides some incremental dosimetric improvements beyond cardiac-optimized VMAT, the clinical significance of which remains uncertain.
