AB - Background and PurposePrevious work has focussed on changes in drug metabolism caused by altered activity of CYP3A in the presence of inflammation and, in particular, inflammation associated with malignancy. However, drug metabolism involves a number of other P450s, and therefore, we assessed the effect of cancerrelated inflammation on multiple CYP enzymes using a validated drug cocktail.Experimental ApproachPatients with advanced stage ovarian cancer and healthy volunteers were recruited. Participants received caffeine, chlorzoxazone, dextromethorphan, and omeprazole as in vivo probes for CYP1A2, CYP2E1, CYP2D6, CYP3A, and CYP2C19. Blood was collected for serum Creactive protein and cytokine analysis.Key ResultsCYP2E1 activity was markedly upregulated in cancer (6hydroxychlorzoxazone/chlorzoxazone ratio of 1.30 vs. 2.75), while CYP3A phenotypic activity was repressed in cancer (omeprazole sulfone/omeprazole ratio of 0.23 vs. 0.49). Increased activity of CYP2E1 was associated with raised serum levels of IL6, IL8, and TNFα. Repression of CYP3A correlated with raised levels of serum Creactive protein, IL6, IL8, and TNFα.Conclusions and ImplicationsCYP enzyme activity is differentially affected by the presence of tumourassociated inflammation, affecting particularly CYP2E1 and CYP3Amediated drug metabolism, and may have profound implications for drug development and prescribing in oncological settings.
