This study intends to optimize a fluorouracil/irinotecan chemotherapy regimen by the identification of individual thymidylate synthase (TS) and UDP-glucuronosyltransferase 1 (UGT1A1) polymorphisms before the first administration.

The results of this identification determine the chemotherapy type: high-dose irinotecan or not.

Condition Intervention Phase
Metastatic Colorectal Cancer
Drug: irinotecan
Drug: 5 fluorouracil
Phase 4

Study Type: Interventional
Study Design: Allocation: Non-Randomized
Intervention Model: Single Group Assignment
Masking: Open Label
Primary Purpose: Treatment
Official Title: Protocole Evaluant Chez Des Patients Porteurs de Cancers Colorectaux Metastatiques l'Interet Des Determinants Genotypiques Pour l'Optimisation de l'Efficacite et de la Tolerance de la Chimiotherapie Par Irinotecan et 5-fluorouracile
