|Condition or disease||Intervention/treatment||Phase|
|Neoplasms||Drug: Capecitabine, 5-fluorouracil||Phase 1|
Patients exhibiting a genetically determined disorder (DPYD*2A) in the metabolic degradation of the frequently used anticancer agents capecitabine and 5-FU (fluoropyrimidines) are at high risk of development of severe and life-threatening toxicity during standard treatment with these compounds. Treatment and recovery of this fluoropyrimidine-induced severe toxicity often requires prolonged periods of hospitalization.
Screening for DPYD*2A in patients to treat with fluoropyrimidine drugs with subsequent dose adjustments in mutant individuals prior to start of therapy will possibly reduce the number of severe toxicity events. Furthermore, by reducing the frequency and/or duration of hospitalization, substantial medical costs can be saved, making this a cost-effective strategy.

Patients are screened for a DPD-deficiency. Patients with a DPYD*2A mutation are eligible for intervention with capecitabine/5-FU .
Drug: Capecitabine, 5-fluorouracil
Patients to treat with capecitabine/5-FU will be screened prior to start of therapy for DPYD*2A. Patients heterozygous or homozygous mutant for DPYD*2A receive dose reductions of capecitabine/5-FU of at least 50% in the first two courses. In case this dose is tolerated well, doses will be increased.
In addition, the pharmacokinetics of capecitabine/5-FU and their metabolites will be assessed in these patients.
- safety [ Time Frame: during fluoropyrimidine treatment of the patient ]
- cost-effectiveness [ Time Frame: during fluoropyrimidine treatment of the patient ]
