ObjectivesTo investigate the impact of opioid use on cancer recurrence after oral cancer surgery. We hypothesized that the amount of opioids administered during oral cancer surgery is an independent predictor of recurrence free survival (RFS) and overall survival (OS).MethodsAfter Institutional Review Board approval, we collected demographic, tumor related, intraoperative and survival data of patients who had oral cancer surgery. Multivariable Cox proportional hazards models were used to determine the impact of important covariates on RFS and OS.Results268 patients were included. After adjusting for significant covariates, the amount of opioids administered during surgery was not an independent predictor of RFS (HR: 1.27 [CI 95%, 0.838–1.924], p=0.26). However, we observed an association between opioid consumption and shorter OS (HR=1.77, [CI 95%=0.995–3.149]. p=0.05).ConclusionsHigh requirements of opioids during surgery increase the risk of recurrence and mortality by 27% and 77%, although the association is not statically significant.
