[Possible cardiotoxicity induced by orally administered fluoropyrimidines].
Camps C., Godes M., Soler JJ.
4 more cases of cardiotoxicity associated to 5-FU or oral fluoropirimidine (Ptorafur, UFT) in patients without previous heart disease (except in one case) are presented. The toxicity found was myocardial ischemia and EKG changes (in 3 patients) in patients whose enzymes were measured. The etiopathogenesis and features of this toxicity are discussed.
