We studied whether total gastrectomy for gastric cancer would affect the pharmacokinetics of 5-fluorouracil (5-FU) and its degradation products, such as dihydrouracil (FUH(2)) and alpha-fluoro-beta-alanine (FBAL), after oral administration of the fluorouracil derivative S-1, composed of tegafur, 5-chloro-2,4-dihydroxypyridine (CDHP; a

The aim of this study was to identify the route of administration of 5-FU with the greatest pharmacological advantage in a rat model using non-invasive in vivo 19F nuclear magnetic resonance (NMR) spectroscopy. 5-FU (50 mg/kg) was administered to anesthetized

Capecitabine (Xeloda) is a novel, oral fluoropyrimidine carbamate rationally designed to generate 5-fluorouracil (5-FU) preferentially in tumor tissue via a three-step enzymatic cascade. The objective of this study was to compare the pharmacokinetics of capecitabine and its metabolites in Japanese

A new sensitive and specific HPLC-MS/MS method for the determination of α-fluoro-β-alanine (FBAL), the main metabolite of the antineoplastic drug 5-fluorouracil (5-FU), in urine for the biological monitoring survey of health care workers exposed to 5-FU is described. This procedure

Cardiotoxicity is a rare complication occurring during 5-fluorouracil (5-FU) treatment for malignancies. We herein report the case of a 70-year-old man with 5-FU-induced cardiotoxicity, in whom a high serum level of alpha-fluoro-beta-alanine (FBAL) was observed. The patient, who had unresectable
