Cardiovascular follow up will be identical to that recommended and realized in current care in the Cardio-Oncology unit of AP-HM. It will include clinical, biological (BNP and troponin) and trans-thoracic echocardiography (TTE) at baseline and then at 1, 3 and 6 months. Auto-antibodies against troponin I assay will be performed to avoid false negatives of normal blood level of troponin I at baseline and then at 6 months. Cardiac MRI will be performed as well at baseline and at the end of the study (6 months). MRI is the gold standard for ventricular function evaluation.
