Abstract Introduction: Regorafenib is a multi tyrosin-kinase inhibitor prescribed in metastatic refractory colorectal cancer treatment. Its toxicity is significant but inconstant. The metabolism of regorafenib includes oxydation via cytochrome P3A4, then glucuroconjugation. A pharmacogenetical approach of mutational status of Uridine-Diphospho-Glucuronosyltransfersase (UDP-glucuronosyl-transferase, UGT) could be a strategy to optimise the use of regorafenib. Patients and Method: This is a restrospective, unicentric study. All adult patients treated with regorafenib for a metastatic colorectal cancer in our center between 2013 and 2017 were analysed. UGT1A1 polypmorphism was previously researched in the laboratory after written informed consent. Results: Thirty-five patients received regorafenib during the study… More >
