While parotid-sparing intensity modulated radiotherapy (IMRT) has demonstrated superiority to conventional RT in terms of observer-rated xerostomia, patient-reported outcome measures (PROMs) have only marginally improved. We investigated how sparing all salivary glands affects PROMs. ⋯ Reducing doses to all salivary glands maximizes PROMs. A cSMG dose constraint of ≤39Gy does not increase failure risk.
