Dosimetry for Patients who Experienced ≥3 Esophageal Toxicity After Treatment.^a

Patient	Site	Event Grade	D_5cc, Gy		D_3.5cc, Gy		D_1cc, Gy		D_Max, Gy		RL, mm	AP, mm	PTV, mm	DSC
Patient	Site	Event Grade	Plan	Actual	Plan	Actual	Plan	Actual	Plan	Actual	RL, mm	AP, mm	PTV, mm	DSC
1	RML	3	18.4	30.5	27. 0	36.8	40.6	41.8	42.5	43.3	−1.7	−0.8	−3.9	0.61
2	RML	3	26.4	30.5	36.4	38.2	44.1	44.2	45.0	45.0	−0.4	1.1	1.0	0.80

Abbreviations: AP, anterior–posterior; CBCT, cone beam computed tomography; CT, computed tomography; DCS, Dice similarity coefficients; PTV, planning target volume; RL, right–left.

^aThe actual dose is the median predicted treatment dose per fraction. AP: median posterior motion. PTV: median movement away (+) or towards (−) the PTV. DSC: median DSC between the esophagus contours for each CBCT scan versus the planning CT scan with a lower DSC representing overlap. RL: median leftward motion.
