Early anthracycline cardiotoxicity in adolescents and young adults with sarcoma: a prospective echocardiographic study

ESC Heart FailPublished

  • prospective echocardiographic study
  • single tertiary cancer centre
  • echocardiograms interpreted by a single cardiologist

Authors' conclusion

Over one-third of AYAs with sarcoma met the primary endpoint at 1 year, with half of these abnormalities persisting at 2 years, primarily driven by LVWT/D ratio reductions. Subclinical changes in strain and diastolic function were observed, reflecting the broad cardiac impact of high-dose Dox in this population.

Study context

Population
Adolescents and young adults (15–39 years) with sarcoma treated with high-dose doxorubicin at a tertiary cancer centre (2018–22)56 completed at least two of three study echocardiograms
Participants
70 adolescents
Outcome
>10% absolute reduction in LVEF, an absolute LVEF <50%, or >10% decrease in LVWT/D ratio from baseline
Follow-up
1 and 2 years
