Clinical Pharmacogenetics Implementation Consortium guidelines for dihydropyrimidine dehydrogenase genotype and fluoropyrimidine dosing.
The fluoropyrimidines are the mainstay chemotherapeutic agents for the treatment of many types of cancers. Detoxifying metabolism of fluoropyrimidines requires dihydropyrimidine dehydrogenase (DPD, encoded by the DPYD gene), and reduced or absent activity of this enzyme can result in severe, and sometimes fatal, toxicity. We summarize evidence from the published literature supporting this assoc...
متن کاملFamilial Deficiency of Dihydropyrimidine Dehydrogenase
Severe neurotoxicity due to 5-fluorouracil (FUra) has previously been described in a patient with familial pyrimidinemia. We now report the biochemical basis for both the pyrimidinemia and neurotoxicity in a patient we have recently studied. After administration of a "test" dose of FUra (25 mg/m2, 600 gCi 16-3HJFUra by intravenous bolus) to a patient who had previously developed neurotoxicity a...
متن کاملRegulation of dihydropyrimidine dehydrogenase in colorectal cancer.
Dihydropyrimidine dehydrogenase (DPD) is responsible for degradation of the pyrimidines uracil and thymine and the inactivation of the chemotherapeutic agent 5-fluorouracil. DPD activity is highly variable in cancer populations, and this variation may influence the antitumor efficacy of 5-fluorouracil. However, little is known about the regulation of DPD mRNA expression in any tissues. Using a ...
متن کاملClinical implications of dihydropyrimidine dehydrogenase inhibition.
Dihydropyrimidine dehydrogenase (DPD) is the initial, rate-limiting enzyme in the catabolism of 5-fluorouracil (5-FU). DPD has an important role in regulating the availability of 5-FU for anabolism. It is now clear that DPD also accounts for much of the variability observed with the therapeutic use of 5-FU, including variable drug levels during 24-hour infusion, erratic pharmacokinetics, variab...
متن کاملDehydrogenase Gene Transcription in Cancer Cells Activator Protein Accelerates Dihydropyrimidine
Dihydropyrimidine dehydrogenase is the most extensively investigated predictive marker for individual response to 5fluorouracil. Clinical responses to the anticancer agent, along with various reports, have clearly shown that dihydropyrimidine dehydrogenase activity is closely correlated to its mRNA levels, but the regulatory mechanisms of its expression have remained unclear. We attempted to cl...
