Subclinical cardiac damage monitoring in breast cancer patients treated with an anthracycline-based chemotherapy receiving left-sided breast radiation therapy: subgroup analysis from a phase 3 trial.
Trial report in La Radiologia medica, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers, 1 of them a synthesis that pooled it.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectiveThis study, derived from the phase 3 SAFE trial (ClinicalTrials.gov identifier: NCT2236806), explores subclinical cardiac damage in breast cancer patients receiving anthracycline-based chemotherapy and left-sided breast radiation therapy (RT). MATERIALS AND
methodsEligible patients were randomized to a cardioprotective pharmacological therapy (bisoprolol, ramipril, or both) or placebo, with cardiac surveillance at multiple time-point using standard and 3-dimensional echocardiography. Dosimetric parameters were analysed, including mean heart dose (MHD) and various metrics for heart substructures, employing advanced contouring techniques and auto-contouring software.
resultsIn the analysis of left-sided breast RT patients, the study encompassed 39 out of 46 irradiated individuals, focusing on GLS and 3D-LVEF outcomes with ≥ 10% worsening, defined as subclinical heart damage. Distinct RT schedules were used, with placebo exhibiting the highest ≥ 10% worsening (36.4%). In terms of treatment arms, bisoprolol exhibited 11.1% worsening, while ramipril 16.7% and bisoprolol + ramipril 25%. For patients with no subclinical damage, the mean MHD was 1.5 Gy; for patients with subclinical heart damage, the mean MHD was 1.6 Gy (p = 0.94). Dosimetric parameters related to heart and heart substructures (left anterior descending artery, right and left atrium, right and left ventricle) showed no statistically significant differences between patients with and without subclinical damage.
conclusionOur results emphasize the crucial role of cardioprotective measures in mitigating adverse effects, highlighting RT as having negligible influence on cardiac performance. An extended follow-up assessment of the whole series is warranted to determine whether a subclinical effect could significantly influence clinical outcomes and cardiac events.
