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
