A recent retrospective cohort study of the applicants recruited 588 patients after surgery for non-small-cell lung cancer and performed a postoperative follow-up for a medium of 5.2 years. After adjusting the confounding factors with multivariate logistic regression model, perioperative use of dexamethasone (medium dose 10 mg, for prevention of postoperative nausea and vomiting) was associated with prolonged survival (HR 0.70, 95% CI 0.54-0.89; P = 0.004); perioperative use of flurbiprofen axetil (medium dose 200 mg, for postoperative analgesia) was also associated with a slightly longer survival but not statistically significant (HR 0.81, 95% CI 0.63-1.03; P = 0.083). Further analysis showed that combined administration of dexamethasone and flurbiprofen axetil had additive effect in prolonging survival (compared to no use of both: adjusted HR 0.57, 95% CI 0.38-0.84, P = 0.005).
