Cardiac risk test using breast cancer radiotherapy scans to guide decisions

Official title: ARTILLERY-CarDI, Early Detection of Non-communicable Disease Risk in People With Breast Cancer: Multicenter Cardiac Decision Impact Study

Run by UMC Utrecht · NCT07703033 · Data updated 2026-11-12

This study tests whether checking coronary artery calcium on planning CT scans can help patients with breast cancer make informed heart-risk decisions during radiotherapy planning.

Is this trial a fit for you?

Likely a good fit

Ideal candidates are women with breast cancer or DCIS, aged 35 or older, who are planned to receive radiotherapy and can provide informed consent.

Probably not a fit

Patients without significant coronary calcifications or with limited life expectancy may not experience meaningful cardiovascular risk changes from this approach.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This multicenter interventional study uses routine radiotherapy planning CT scans to measure coronary artery calcifications and communicates the associated cardiovascular risk to patients. The goal is to see how this information affects patients’ understanding and decisions about their treatment. The trial involves women with breast cancer (or DCIS) who are planned for radiotherapy and are 35 or older. Results will inform whether incorporating CAC assessment into planning improves patient-centered care and decision quality. No results are reported yet since the study design is to observe the impact of this communication strategy.

Why it matters

Potential benefit: If successful, patients may make more informed choices about their treatment and cardiovascular risk management.

How similar studies have gone: Previous work suggests that sharing imaging-based cardiovascular risk information can influence patient decisions, though this exact CAC-based communication during RT planning is relatively novel.
