| Main Objective: To prospectively determine whether fluoropyrimidine-induced toxicity is preventable by dose adjustment prior to start of the first administration based on the polymorphic status of the DPYD*2A polymorphism in DPYD, in comparison with retrospectively determined full-dose treated heterozygous patients.;Secondary Objective: • To determine whether adaptive dosing based on polymorphic status of DPYD*2A is cost-saving. • To validate an individualized treatment algorithm for 5-FU and capecitabine therapy based on the polymorphic status of DPYD*2A. • To assess the pharmacokinetic profile of capecitabine and 5-FU in DPYD*2A mutant patients given reduced dosages of the respective drugs. • To estimate the frequency of the DPYD*2A polymorphism in a Dutch cancer population. ;Primary end point(s): To prospectively determine whether fluoropyrimidine-induced toxicity is preventable by dose adjustment prior to start of the first administration based on the polymorphic status of the DPYD*2A polymorphism in DPYD, in comparison with retrospectively determined full-dose treated heterozygous patients. | — |
