Opioid use can induce immunosuppression; however, it is unclear whether opioid use increases infections in patients with advanced cancers. This study assessed the association between opioid use in the week before death and mortality among patients with advanced lung cancer having sepsis. Data on opioid usage in the week before death, general information, and clinical information of the patients were collected retrospectively. The primary outcome was the association between opioid use in the week before death and mortality after sepsis. The study included 980 patients who died of advanced lung cancer between January 2003 and June 2017 (sepsis related: 413, unrelated to sepsis: 567). The average morphine equivalent daily dose in the final week was higher in the sepsis group (313.5 ± 510.5 mg) than in the nonsepsis group (125.2 ± 246.9 mg, P < .001). A significant association was found between the average morphine equivalent daily dose in the final week and mortality due to sepsis (odds ratio: 1.02, 95% confidence interval: 1.01-1.02, P < .001). This was especially evident when the dose was increased by 10 mg in the final week. Furthermore, older age, male sex, and a lower body mass index were associated with an increased risk of mortality after developing sepsis. Opioid use in the week before death may be associated with mortality for patients with advanced lung cancer having sepsis.
