    BackgroundOpioid prescribing has been increasingly scrutinized among noncancer patients. As an unintended consequence, opioids may be underprescribed for cancer patients. The purpose of this study was to compare trends in opioid prescribing in younger adults with and without cancer.MethodsFrom 2004 to 2013, Ontario residents aged 18-64 years eligible for government paid pharmacare were annually stratified into three groups: no cancer history, cancer diagnosis more than five years ago, and cancer diagnosis five years ago and less. We evaluated time trends in two annual outcomes: opioid prescription rate and mean daily opioid dose.ResultsIn 2013, 800,371 individuals were eligible for this study (3% with recent cancer and 2% with remote cancer). Across all years, compared with noncancer patients, overall opioid prescription rates were 43% and 26% higher for those with recent and remote cancer, respectively. Overall, a 1% relative annual increase was seen in those without cancer and a 1% decrease was seen in those with a recent cancer. Changes in prescription rates varied with drug class and cancer group. Notably, long-acting opioids had a relative annual increase of 7% in noncancer patients vs. 2% in recent cancer patients. Immediate-release combination agents had a relative annual decrease of 2% for all cancer groups. Trends in mean daily dose were similar between groups, but by 2013, they were lowest in recent cancer patients, regardless of drug class.InterpretationSecular trends in opioid prescribing affect cancer and noncancer patients similarly. Further research is required to assess the potential impact on symptom management.Copyright © 2018 American Academy of Hospice and Palliative Medicine. Published by Elsevier Inc.
