Echocardiography in adriamycin cardiotoxicity.

K R Bloom, R M Bini, C M Williams

    Cancer
    |April 1, 1978

    Summary

    Adriamycin treatment for osteogenic sarcoma can cause left ventricular dysfunction, but echocardiography helps monitor heart function. Cardiac function often normalizes after adriamycin cessation, minimizing cardiotoxicity risks.

    Area of Science:

    • Cardiology
    • Oncology
    • Medical Imaging

    Background:

    • Adriamycin (doxorubicin) is a key chemotherapy for osteosarcoma.
    • Cardiotoxicity is a significant concern with adriamycin treatment.
    • Monitoring left ventricular function is crucial during therapy.

    Purpose of the Study:

    • To assess left ventricular function in osteosarcoma patients receiving adriamycin.
    • To evaluate the effectiveness of echocardiography in monitoring adriamycin-induced cardiotoxicity.
    • To determine if cardiac function recovers after adriamycin cessation.

    Main Methods:

    • Serial echocardiographic assessments were performed on 26 patients.
    • Left ventricular function was evaluated using parameters like ejection fraction (EF) and velocity of circumferential fibre shortening (Vcf).
    • Therapy was adjusted based on echocardiographic findings.

    Main Results:

    • A statistically significant decline in left ventricular function was observed during adriamycin therapy.
    • Velocity of Circumferential Fibre Shortening (Vcf) and Ejection Fraction (EF) were sensitive indicators of cardiotoxicity.
    • Cardiac function tended to normalize post-treatment.
    • Only one patient experienced fatal congestive heart failure.

    Conclusions:

    • Echocardiography is a valuable tool for monitoring adriamycin cardiotoxicity in osteosarcoma patients.
    • Serial echocardiography allows for timely intervention, improving the therapeutic index of adriamycin.
    • Proactive monitoring can mitigate the risk of severe cardiac events.
