Prevalence and risk factors associated with chronic pain among survivors of head and neck cancer.

e18016 Background: There are over 500,000 survivors of head and neck cancer (HNC) in the United States. Pain is one of the most common symptoms of HNC due to disease anatomy, treatment and post-treatment toxicities. While opioid treatment is a mainstay in HNC care, factors associated with chronic pain are not properly understood. Methods: We built a retrospective cohort of adult patients with a history of HNC using the National Health Interview Survey (NHIS) from 2010 to 2021 that collected through personal household interviews ( n = 353). Chronic pain was defined using the question: In the past three months, how often did you have pain? Would you say never, some days, most days, or every day? Chronic pain was coded as “yes” if the response was most or every day, and “no” if it was never or some days. Using weighted logistic regression analysis adjusting for age and sex, we examined the association between chronic pain and sociodemographic (race, insurance, education, income, employment and smoking history) and clinical (depression, and self-rated health status) factors. Results: Among individuals with a history of HNC, 149 (adjusted Prevalence Rate = 43.2%; 95% CI: 36.6%, 49.8%) had experienced chronic pain in the past three months. There were significant associations with clinical factors, as individuals with poor self-rated health (aOR = 6.42; 95% CI: 3.25, 12.70) and those with depression (aOR = 3.25; 95% CI: 1.73, 6.11) had increased odds of reporting chronic pain. Among sociodemographic factors White race (aOR = 2.52, 95% CI: 1.04, 6.10) and Medicaid insurance (aOR = 3.76, 95% CI: 1.40, 10.10) were associated with and increased odds of reporting chronic pain. There was no significant association of education, income, employment or smoking history with chronic pain among the study HNC survivors. Conclusions: Over 40% of individuals with a history of HNC may be living with chronic pain, unequally distributed based on race, payor status and comorbid depression. Given the current opioid crisis in the United States, and the poor outcomes associated mental health in cancer survivors, our findings highlight clinical and social determinants of health factors that should be taken into the consideration for management of chronic pain among survivors of HNC patients.
