Detailed Description
The fluoropyrimidines, of which 5-Fluorouracil is the most important, represent a family of medication that is used in particular in cancerology. They are molecules widely used in cancerology since they can be found in nearly 45% of chemotherapy protocols and in the treatment of about 50% of cancers (colorectum, oesophagus, stomach, breast, upper digestive and respiratory tracts). They are not only used in metastatic situations but also more and more in adjuvant situations, in other words for patients treated for a localised tumour, presenting a risk of relapse. A severe toxic risk cannot be tolerated in these conditions, and the doctor should assure the maximum level of safety for his patients. These medicines are the cause of 3% of grade IV toxicity from the first or second administration, and for 0.3% of deaths. To this one can add on a total of 20 to 25% grade III-IV toxic events.
Anticancer treatment is mostly administered by body size and in the best of cases after a few basic biological examinations such as a haemogram and renal status, without taking into consideration any individual particularities, whether genetic or epigenetic. Among potential toxicity risk factors one can find individual metabolic differences linked to genetic modifications of metabolism enzymes as well as differences in the chemical receptors and transporters.
For fluoropyrimidines, a polymorphism was found for the dihydropyrimidine dehydrogenase gene (DPD), a major catabolism enzyme. A deficit of this enzyme is a major counter-indication for the use of these medicines.
Early determination of DPD status would allow identification of patients at risk and would thus help in subsequent dose adjustment or selection of other treatment modalities.

Participant Group / ArmParticipant Group / Arm |
Intervention / TreatmentIntervention / Treatment |
|---|---|
|
Experimental: A : pre-therapeutic screening for DPD deficiency
Prior to treatment by fluoropyrimidines,a DPD deficiency is identified by a joint phenotypic-pharmacogenetic approach.
|
Prior to treatment by 5-FU, a DPD deficiency is identified thanks to just one blood sample (lithium heparinate).
Blood sample (lithium heparinate) will be taken prior to treatment but not analysed.
|
|
Other: B : no pretherapeutic research of DPD deficiency
For patients included in this arm, a blood sample will be taken prior to treatment by fluoropyrimidines but not analysed.
If grade 3 or 4 toxicity levels are encountered during treatment, DPD deficiency will be detected.

Prior to treatment by 5-FU, a DPD deficiency is identified thanks to just one blood sample (lithium heparinate).
Blood sample (lithium heparinate) will be taken prior to treatment but not analysed.

Number and nature of grade IV toxicity.
Time Frame: Up to 4 weeks.
|
The percentage of severe toxicity (grade IV) will be analyzed in each arm.
We expect a reduction of the early, severe, grade IV acute side-effects from 3% to 0.6% in the detected group with adapted doses.
|
Up to 4 weeks.

|
We will carry out a comparison of the prevention costs and the costs related to treating patients with toxicity.
Direct costs and indirect costs will be taken into account.
