Step 2: Planning comparison
Estimation of dose difference (Δdose)
Standard IMRT:
Dose reduction parotid glands
No dose constraints for SWOARs
D
mean
superior PCM = 64 Gy
D
mean
supraglottis = 60 Gy
Swallowing sparing IMRT (SW-IMRT)
:
Dose reduction parotid glands
Dose reduction SWOARs
D
mean
superior PCM = 54 Gy
D
mean
supraglottis = 30 Gy
