  • Title: [Is the use of adriamycin (doxorubicin) limited by its cardiotoxicity?].
    Author: Reinhardt D, Hofmann V, Martz G.
    Journal: Schweiz Med Wochenschr; 1985 Apr 20; 115(16):557-61. PubMed ID: 4001904.
    Abstract:
    Adriamycin (doxorubicin), one of the most active cytotoxic antineoplastic agents, can cause heart failure. This side effect is dose-dependent, the frequency of heart failure being 3% at a cumulative Adriamycin dose of 400 mg/m2 and 18% at 700 mg/m2. It is assumed that Adriamycin, or other anthracycline derivatives, are still active when the cardiotoxic level is reached. In this retrospective study of 171 patients with various metastatic malignant tumors, the total dose of Adriamycin given to the patients and the reasons for withholding the treatment have been analyzed. Overall, among the 171 patients treated by Adriamycin-containing combination chemotherapy, 54 objective remissions (31%) were observed. Remissions were more frequent in untreated patients (52%) than in previously treated patients (20%). In 36 of 54 patients the disease progressed before the cumulative cardiotoxic level was reached. Adriamycin could be discontinued in only 18 patients still in remission. 8 of 171 patients received more than 450 mg/m2 Adriamycin without cardiotoxic side effects being observed. Among the 171 patients, cardiotoxicity probably related to anthracyclines developed in 5 cases (3%), in all cases at a level below 450 mg/m2. These results suggest that in most cases Adriamycin becomes inactive before the dose-limiting cumulative cardiotoxic level is reached.
