Breast Cancer
Conditions
Brief summary
The combination of epirubicin-cyclophosphamide (EC) and paclitaxel (Tax) is one of the main chemotherapy treatments used in breast cancer patients. These treatments, which can be combined with anti-HER2 therapy using trastuzumab, are frequently associated with side effects including cardiac toxicity. However, this cardiac toxicity has only been demonstrated several months after treatment and using global indices such as ejection fraction. The assessment of myocardial dysfunction using regional deformations and the kinetic of this dysfunction during chemotherapy treatment has never been performed. In order to counteract these myocardial dysfunctions, it is essential to better describe the kinetic of the cardiac toxicity by initiating measurements since the beginning of the treatment, in order to be able to propose adapted countermeasures (e.g. exercise training) in parallel with the chemotherapy.
Interventions
OTHERCardiac evaluation
In order to obtain information on the body composition of the patients, a body composition measurement will be performed. A resting cardiac echocardiography will be performed to record myocardial deformations in a non-vulnerable way. A non-invasive evaluation of arterial function will be performed by ultrasound on the femoral artery during a standardized passive movement of the leg. An assessment of myocardial deformations will also be performed under submaximal exercise conditions (at a target heart rate of 120 beats per minute, low to moderate exercise intensity). All of these measurements will be performed during evaluation 1 and reproduced in the same way during the 4 other sessions planned during (evaluation 2, 3 and 4) and after the treatment (evaluation 5).

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Studying the impact of chemotherapy combining EC and Tax on myocardial deformations (at rest and at submaximal effort) in order to identify the kinetic of systolic and diastolic dysfunctions. | During the treatment period, approximately 16 to 21 weeks | Characterizing the alteration of global longitudinal strain (GLS) by resting echocardiography at rest before, during, and after chemotherapy in a group of breast cancer patients receiving EC and Tax. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Studying the kinetic of the development of vascular dysfunction in order to understand a potential vascular dysfunction that could occur during treatment with chemotherapy combining EC and Tax. | During the treatment period, approximately 16 to 21 weeks | Analyze changes in myocardial deformations during submaximal exercise, vascular function assessed non-invasively by femoral artery ultrasound, and changes in the presence of markers of myocardial injury in the blood compartment. |
| To compare myocardial deformations (at rest and under submaximal stress) between patients treated with EC + Tax to patients treated with trastuzumab. | During the treatment period, approximately 16 to 21 weeks | Comparison of myocardial deformations changes induced by two types of treatment: EC + Tax and Trastuzumab. For this endpoint, we will compare the end of chemotherapy treatment to the end of trastuzumab treatment. |
