Cardiac Toxicity of 5-Fluorouracil: A Study on 1083 Patients

Abstract

The possible onset of cardiotoxic manifestations during chemotherapy with 5-fluorouracil (5-FU) was evaluaetd in 1083 patients treated with the drug for various kinds of neoplasm. We recognized 17 cases of 5-FU cardiopathy (usually anginous crises but also myocardial infarction). The comprehensive incidence was 1.6 %, with a significantly greater risk (4.5 % vs 1.1 %) for patients with a positive anamnesis of previous cardiopathy. On the contrary, age and combination with other antiblastic drugs had no affect on the appearance of cardiopathy. We conclude that 5-FU cardiopathy, although rare, has to be taken into account in oncologic practice, chiefly in those patients already affected with cardiac diseases.
