title: Studies on adriamycin using a weekly regimen demonstrating its clinical effectiveness and lack of cardiac toxicity.
abstract: Adriamycin has been given to 442 patients using the weekly regimen as initially described by Bonadonna et al. Hematologic toxicity and clinical effectiveness have been similar to those described with regimens in which the drug is given every 3 weeks. Stomatitis is more frequent with the weekly regimen than with the usual triweekly regimen. The incidence of electrocardiographic changes and arrhythmias was similar to that reported in other studies. Nine patients received between 500 and 550 mg/m2, nine between 550 and 600 mg/m2, 28 between 600 and 1000 mg/m2, and 22 between 1000 and 2500 mg/m2. None of the patients developed definite evidence of cardiomyopathy although six showed some disturbance of myocardial function. In each of the six patients, factors other than adriamycin cardiotoxicity were believed to play a major role in the myocardial abnormality. The difference between the incidence of cardiomyopathy seen in this series and that previously reported is statistically significant. The reasons for the difference are not clear but are probably related to the schedule that was used.
