Abstract :
[en] AIMS: This study assessed the impact of the strain-guided therapeutic approach on cancer therapy-related cardiac dysfunction (CTRCD) and rate of cancer therapy (CT) interruption in breast cancer. METHODS AND RESULTS: We enrolled 116 consecutive female patients with HER2-positive breast cancer undergoing a standard protocol by EC (epirubicine + cyclophosphamide) followed by paclitaxel + trastuzumab (TRZ). Coronary artery, valvular and congenital heart disease, heart failure, primary cardiomyopathies, permanent or persistent atrial fibrillation, and inadequate echo-imaging were exclusion criteria. Patients underwent an echo-Doppler exam with determination of ejection fraction (EF) and global longitudinal strain (GLS) at baseline and every 3 months during CT. All patients developing subclinical (GLS drop >15%) or overt CTRCD (EF reduction <50%) initiated cardiac treatment (ramipril+ carvedilol). In the 99.1% (115/116) of patients successfully completing CT, GLS and EF were significantly reduced and E/e' ratio increased at therapy completion. Combined subclinical and overt CTRCD was diagnosed in 27 patients (23.3%), 8 at the end of EC and 19 during TRZ courses. Of these, 4 (3.4%) developed subsequent overt CTRCD and interrupted CT. By cardiac treatment, complete EF recovery was observed in two of these patients and partial recovery in one. These patients with EF recovery re-started and successfully completed CT. The remaining patient, not showing EF increase, permanently stopped CT. The other 23 patients with subclinical CTRCD continued and completed CT. CONCLUSION: These findings highlight the usefulness of 'strain oriented' approach in reducing the rate of overt CTRCD and CT interruption by a timely cardioprotective treatment initiation.
