9530 Background: OPC treatment is associated with significant long-term toxicity. Very little is known about the long-term symptom burden and orodental health in OPC survivors >2 yrs from treatment. Methods: Survivors treated for OPC with CRT/ST (involving definitive RT) at Dana Farber Cancer Institute between 2002-2011 and >2 yrs from treatment completion, were identified by chart review and asked to complete the Vanderbilt Head and Neck Symptom Survey version 2 (VHNSS v2), National Health And Nutrition Examination Survey for Oral Health Questionnaire, health care availability survey. Results: 200 survivors were contacted, 127 responded (RR: 64%). Median age at diagnosis was 54 yrs; 85% males; 85% stage IVA/B, 13% stage III; 56% CRT, 43% ST. HPV status: 47% (+), 10% (-), 43% unknown. Median time from treatment completion: 50 mths (24-135 mths). Residual moderate to severe toxicities reported in VHNSS v2: 71% dry mouth; 59% difficulty chewing/swallowing food; 53% feeling of food becoming stuck in the throat; 53% prolonged time to eat; 31% thick mucus, 6% had difficulty sleeping secondary to this; 16% trouble speaking, 27% trouble hearing;30% limitation of neck/shoulder movement; altered taste/smell - 45%/23%; sensitivity to spicy food and dryness-57%/62%; 30% decreased desire to eat, 11% had moderate weight loss. Orodental health assessment: 13% thermal sensitivity, 21% teeth cracking and chipping, 20% loose teeth, 33% had treatment for gum disease, 42% had lost bone around teeth. 98% survivors had health insurance; only 66% had dental insurance. No statistically significant difference was noted with respect to symptoms between CRT or ST. ST did not affect long-term toxicity compared to CRT alone. Conclusions: OPC is known to correlate with HPV positivity, early age at diagnosis and high rates of long-term survival after appropriate therapy. Our study documents that the OPC survivors have substantial residual long-term head and neck and orodental symptoms directly related to the treatment that significantly impacts their quality of life. A substantial number of patients lack dental health coverage, which likely further impacts symptom burden and QOL.
