JACC CardioOncolPublication date not resolved

  • Non-randomised clinical trial
  • single-group

Authors' conclusion

Reduced CTRCD surveillance every 6 months is safe and feasible for patients at low risk for CTRCD

Study context

Population
Patients with HER2-positive breast cancer treated with non-anthracycline HER2-targeted therapy; excluded: previous anthracycline exposure, significant CVD, uncontrolled hypertension
Participants
190 patients
Comparison
Reduced cancer therapy-related cardiac dysfunction (CTRCD) surveillance (echocardiography every 6 months) during non-anthracycline HER2-targeted therapy
Primary endpoint
Cardiac event rate:
  • HF
  • CV death
Follow-up
1 year

Primary result

As reported in the abstract

Cardiac events:
  • HF
  • CV death
· median follow-up 17.5 months (Q1-Q3: 16.3-18.9 months)

Cardiac events

0 (0%; 1-sided 97.5% CI: 0%-1.9%)

Secondary outcomes

Asymptomatic CTRCD

Asymptomatic CTRCD, 1 patient; resumed therapy after temporary treatment interruption
0.5%; 95% CI: 0.01%-2.9%

Adherence to reduced surveillance schedule every 6 months

Adherence, ITT
73.2%
Adherence, per-protocol
79.9%
