Pretreatment serum uracil concentration as a predictor of severe and fatal fluoropyrimidine-associated toxicity

摘要

Background:We investigated the predictive value of dihydropyrimidine dehydrogenase (DPD) phenotype, measured as pretreatment serum uracil and dihydrouracil concentrations, for severe as well as fatal fluoropyrimidine-associated toxicity in 550 patients treated previously with fluoropyrimidines during a prospective multicenter study.
