RESUMO
OBJECTIVE: In the context of the opioid epidemic, there is value in examining the use of opioids in specific cancer patient cohorts. We analyzed opioid use in patients undergoing adjuvant therapy for oral cavity cancer to define the incidence of new persistent use beyond 3 months. STUDY DESIGN: Retrospective. SETTING: Comprehensive academic cancer center. SUBJECTS AND METHODS: We performed a retrospective IRB-approved analysis of opioid use in patients who received adjuvant radiotherapy with or with concurrent systemic therapy for surgically resected oral cavity cancer between 2003 and 2016. Factors associated with opioid use were evaluated by Chi-square test and one-way ANOVA. The Kaplan-Meier method was used to estimate overall survival. RESULTS: Of 77 identified patients, 10 (13%) patients received opioid prescriptions at 3 months or greater following completion of radiotherapy. Patients who were opioid naive prior to surgery required significantly fewer opioid prescriptions than intermittent or chronic opioid users. No specific factors were associated with new persistent opioid use. CONCLUSIONS: Patients undergoing surgery and adjuvant radiotherapy for oral cavity cancer who required opioids for cancer treatment related pain are at minimal risk for new dependency. Judicious pain management should be applied for patients with a history of prior opioid use. Larger patient cohorts will be needed to identify patient, disease, and treatment characteristics associated with new persistent use given its limited incidence.
