Personalized medicine is becoming an important tool in oncology, both in preventing disease and in optimizing the treatment of existing cancers. Here we describe the cases of 2 patients with relevant systemic toxicity following 5-fluorouracil (5-FU) therapy and we study the more frequent
Irinotecan and 5-fluorouracil (5-FU) are used to treat metastatic colorectal cancer. Irinotecan's active metabolite is inactivated by UDP-glucuronosyltransferase 1A1 (UGT1A1), which is deficient in Gilbert's syndrome. Irinotecan and metabolites are transported by P-glycoprotein, encoded by ABCB1.
5-Fluorouracil (5-FU), the mainstay of solid tumor chemotherapy over the past 40 years, induces grade III-IV toxicities in up to 15% of patients with polymorphisms in the dihydropyrimidine dehydrogenase (DPYD), thymidylate synthase (TYMS), and methylenetetrahydrofolate reductase (MTHFR) genes. These
OBJECTIVE
Germinal gene polymorphisms can explain a part of the interpatient pharmacodynamic variability of anticancer drugs, particularly fluoropyrimidines. Genes for which polymorphisms may potentially influence pharmacodynamics of fluoropyrimidines, including capecitabine, are thymidylate
