ED visits, hospital admissions and treatment breaks in head/neck cancer patients undergoing radiotherapy.

Objectives: Radiation therapy (RT) is an integral part of treatment of head/neck cancer (HNC) but is associated with many toxicities. We sought to evaluate sociodemographic, pathologic, and clinical factors associated with emergency department (ED) visits, hospital admissions (HA), and RT breaks in HNC patients undergoing curative-intent RT. Methods: We completed a Level 3 (Oxford criteria for evidence-based medicine) analysis of a cohort of HNC patients who underwent curative-intent RT at our institution from 2013 to 2017. We collected demographic characteristics and retrospectively assessed for heavy opioid use, ED visits or HA during RT as well as RT breaks. Treatment breaks were defined as total days to RT fractions ratio ≥1.6. Multivariable stepwise logistic regression analyses were done to determine the association of various sociodemographic, pathologic, and clinical characteristics with ED visits, HA and RT treatment breaks. Results: The cohort included 376 HNC patients (294 male, 82 female, median age 61). On multivariable analysis, significant factors associated with ED visits during RT were heavy opioid use and black race. Receipt of concomitant chemotherapy was the only factor associated with hospital admissions during RT. Advanced age, lower socioeconomic class, glandular site, and receipt of chemotherapy were all independently associated with RT breaks. Lower cancer stage and lack of substance abuse history were independently associated with lack of treatment breaks. Conclusion: HNC patients with factors such as heavy opioid use, Black race, receipt of concomitant chemotherapy, and lower socioeconomic class may require closer monitoring during RT.

Opioid use patterns in patients with head and neck cancer receiving radiation therapy: Single-institution retrospective analysis characterizing patients who did not require opioid therapy.

BACKGROUND: We had previously analyzed the variables that determine the rates of opioid use at 1-year postradiotherapy in patients with head and neck cancer. Here we analyze the variables associated with opioid abstinence during and in the 12 months after radiotherapy at our institution. METHODS: We identified a cohort of patients with head and neck cancer who received radiotherapy as part of curative treatment at our institution. Logistic regression analyses were performed to determine socioeconomic and clinical factors associated with opioid abstinence. RESULTS: The cohort included 376 patients. On multivariable analysis, patients from an upper-income class (p = 0.004), black race (p = 0.004), older (p = 0.008), with dependent children (p < 0.001) or receiving surgery (p = 0.002) were more likely to abstain from opioids, while patients using analgesic mouthwash (p = 0.009) or higher pain scale (p = 0.002) were less likely. CONCLUSION: Socioeconomic and treatment characteristics are associated with opioid abstinence during and following radiation treatment in patients with head and neck cancer.

Long-term opioid use in curative-intent radiotherapy: One-Year outcomes in head/neck cancer patients.

BACKGROUND: No study has determined the incidence of long-term opioid use, or risk factors for long-term use, ≥1 year after radiotherapy. METHODS: Medical records of 276 head/neck cancer patients were retrospectively assessed for persistent opioid use 1-year after curative-intent radiotherapy. Numerous potential risk factors were assessed and the physicians' documented reasons for continued use were qualitatively categorized as suspected opioid use disorder (OUD) or as medically indicated for control of ongoing pain. RESULTS: Of note, 20 of 276 patients continued using opioids long-term. High maximum opioid dose and the use of opioids and/or psychotropics/non-opioid analgesics at the radiation oncology intake visit were associated with this outcome. Three patients continued due to suspected OUD and 17 due to medical indications. CONCLUSION: Of note, 7.2% of patients developed long-term opioid use, which was associated with high maximum opioid dose and early initiation of opioids and/or psychotropics/non-opioid analgesics. Physicians cited medical indications as the primary reason for continued use.
