Effect of opioids on cancer survival in patients with chronic pain: a propensity score-matched population-based cohort study.
Abstract
The impact of opioid analgesic use before cancer diagnosis on survival in patients with chronic pain is unclear. Therefore, we designed a propensity score-matched population-based cohort study to compare overall and cancer-related survival of patients with chronic pain who received long-term opioid analgesic treatment with that of those who did not receive such treatment.
