Background/aim: Anthracyclines, such as doxorubicin, though widely used in anticancer therapy, they are associated with cardiotoxic side-effects. The aim of this trial was to investigate long-term follow-up cardiotoxicity findings in patients treated with doxorubicin and concomitant metoprolol or enalapril 10 years earlier.
Patients and methods: Overall, 147 patients were randomized into the treatment arms. A total of 125 patients treated with doxorubicin without evidence of heart disease at the start of chemotherapy were analyzed. They were followed-up for up to 10 years after treatment start.
Results and conclusion: A total of 47 patients completed the follow-up and 21 patients died, none due to cardiotoxicity events. Clinical signs of heart failure were not seen in any patients and no statistically significant differences between baseline and 10-year findings were seen for echocardiographic variables. No evidence of long-term cardiotoxicity was seen and nor metoprolol or enalapril offered an additional benefit.
