TABLE 2.

DVH metrics used to compare plan performance in each ROI. Metrics are adapted from in‐house institutional dose constraints based on the ROSEL trial. Dose metrics are defined as the minimum dose received by the subscripted relative volume of the structure, while volume metrics are defined as the minimum relative volume receiving the subscripted dose.

ROI	DVH Metrics
PTV	D_95%
GTV	D_95%, D_1%
Lungs	V_20Gy, V_5Gy, D_mean
Heart	D_2%
Spine	D_95%, D_1%
Esophagus	D_95%, D_1%

Abbreviations: DVH, dose volume histograms; GTV, gross tumor volume.
