The degree of xerostomia in patients treated for intermediate-and high-grade non-Hodgkin lymphoma (NHL) of Waldeyer's ring (WR) is unknown.Fifteen patients treated for stage I-IV NHL of WR with radiotherapy (RT) were administered a xerostomia questionnaire. Numerical responses (0 = no xerostomia; 100 = maximum xerostomia) were compared with responses from 5 sets of patients treated for head and neck squamous cell carcinoma who were grouped by amount of parotid in RT field: larynx-only, ipsilateral parotid, bilateral-partial parotid, bilateral-total parotid, parotid-sparing intensity-modulated radiotherapy.Waldeyer's patients' median xerostomia questionnaire score was 31, which was significantly different from the larynx-only group, bilateral-partial parotid group, and bilateral-total parotid group, but not significantly different from the ipsilateral parotid group or parotid-sparing intensity-modulated radiotherapy group.Xerostomia in survivors WR NHL is a detectable toxicity with severity like that in head and neck squamous cell carcinoma patients who receive ipsilateral parotid irradiation, and warrants parotid-sparing RT techniques.
