Design outcomes

Primary

MeasureTime frame
Main Objective: 5-fluorouracil (5-FU) is the drug most commonly used in the treatment of patients with colorectal cancer. Its efficacy and toxicity can also be evaluated and predicted according to individual pharmacogenetic (PG), pharmacokinetic (PK) and dynamic data (PD). Individual PK is estimated according to drug plasma concentrations –Cpl and kinetic parameters of 5-FU, mainly the AUC as the measure of exposure to drugs. Clinical outcome which is evaluated according to PD parameters, is more depedent on pharmacokinetics than on the dose. This study is devoted to kinetally guided therapy with 5-FU.;Secondary Objective: a. The final effect of 5-FU is also dependent on PG conditions which determine enzymatic activity of DPD (dihydropyrimidin reductase), TS (thymidylate synthase), and MTHFR (methylfolate reductase). These enzymes undergo genetic polymorphism. There for this study is also interested in the genotype;Primary end point(s): interindividual variability in pharmacokinetics and dynamics (toxicity)
