  "abstract": "Context: Long-term opioid use after radiation therapy remains a clinically important issue among cancer survivors and patients with chronic pain. Identifying factors associated with opioid use at long-term follow-up may help target early interventions and supportive care resources. Objective: To identify demographic, clinical, pain-related, and opioid-related factors associated with opioid use at FU2 (the second follow-up assessment occurring ≥180 days after the completion of radiation therapy). Methods: Retrospective cohort study of patients receiving radiation therapy (RT) with available pain and opioid follow-up data. Opioid use at long-term follow-up (FU2) was defined by active (scheduled or as-needed) opioid prescriptions at ≥180 days after RT. Multivariable logistic regression analyses were performed to identify predictors of opioid use at long-term follow-up (FU2). Candidate predictors included demographic variables, smoking history, opioid use before RT, baseline pain scores, longitudinal pain burden (AUC), and pain scores after RT. Results: Higher opioid use within one week before RT start was independently associated with opioid use at FU2. Weekly pain burden during RT and early post-treatment pain scores demonstrated trends toward significance. Demographic factors, including age, sex, and smoking status, were not significantly associated with opioid use at long-term follow-up (FU2). Conclusions: Pre-treatment opioid exposure was independently associated with opioid use at long-term follow-up (FU2). Prospective studies are required to determine whether pre-treatment opioid optimization improves long-term outcomes.",
