Pharmacokinetics and Pharmacogenetics-based Adaptive Dosing of 5-fu (5-Fluorouracile) in Head & Neck Cancer Patient Undergoing Docetaxel, Cisplatin, 5-Fluorouracile (=TPF) Therapy

Summary

Docetaxel, Cisplatin, 5-Fluorouracile (=TPF) is a mainstay for treating head and neck cancers, but elderly or fragile patients are often precluded because of the risk of severe toxicities associated with this protocol. DPD (Dihydro Pyrimidine Dehydrogenase) deficiency is a pharmacogenetic syndrome responsible for most of the severe/lethal toxicities showing in 5-FU (5-Fluorouracile)-treated patients, and our institute has developed a strategy for the routine determination of Dihydro Pyrimidine Dehydrogenase (DPD) status prior to starting giving the 5-FU so as to roughly adapt drug dosage according to the Dihydro Pyrimidine Dehydrogenase (DPD) status. This project aims at developing a Bayesian strategy to further individualize 5-FU dosing to reach a target exposure of area under curve (AUC). To this end, 100 patients with head and neck cancer and scheduled for a Docetaxel, Cisplatin, 5-Fluorouracile (=TPF) regimen will be included.
