Implications of Treatment Modality on Chronic Opioid Use Following Treatment for Head and Neck Cancer

To investigate the relationship between treatment modality and chronic opioid use in a large cohort of patients with head and neck cancer.

Retrospective cohort study.

Single academic center.

There were 388 patients with head and neck cancer treated between January 2011 and December 2017 who met inclusion criteria. Clinical risk factors for opioid use at 3 and 6 months were determined with univariate and multivariate analyses.

The prevalence of opioid use was 43.0% at 3 months and 33.2% at 6 months. On multivariate analysis, primary chemoradiation (odds ratio [OR], 4.04; 95% CI, 1.91-8.55) and surgery with adjuvant chemoradiation (OR, 2.39; 95% CI, 1.09-5.26) were associated with opioid use at 3 months. Additional risk factors at that time point included pretreatment opioid use (OR, 7.63; 95% CI, 4.09-14.21) and decreasing age (OR, 1.03; 95% CI, 1.01-1.06). At 6 months, primary chemoradiation (OR, 2.40; 95% CI, 1.34-4.28), pretreatment opioid use (OR, 5.86; 95% CI, 3.30-10.38), current tobacco use (OR, 2.00; 95% CI, 1.18-3.40), and psychiatric disorder (OR, 1.79; 95% CI, 1.02-3.14) were associated with opioid use.

Of the patients who receive different treatment modalities, those receiving primary chemoradiation are independently at highest risk for chronic opioid use. Other risk factors include pretreatment opioid use, tobacco use, and a psychiatric disorder. In an effort to reduce their risk of chronic opioid use, preventative strategies should be especially directed to these patients.
