Anthracycline therapy is well-known for its adverse cardiac effects. Anthracycline-induced cardiotoxicity (AIC) is associated with a poor prognosis; since classical heart failure treatment can potentially reverse cardiac dysfunction at the early stage of cardiac toxicity, early detection of AIC is crucial.

Transthoracic echocardiography is recommended for monitoring left ventricular function in patients receiving these molecules. In routine practice, left ventricular systolic function is mainly assessed by the left ventricular ejection fraction (LVEF), measured by two-dimensional echocardiography imaging. However, LVEF depends on the operator's experience and is not sensitive enough to detect subclinical myocardial dysfunction.

To overcome these limitations, two-dimensional speckle-tracking imaging has been proposed. This technique allows for a study of global and regional myocardial deformation, especially the longitudinal component, which appears to be the most sensitive one. Several studies have already emphasized the role of global longitudinal strain (GLS) to detect slight alterations in systolic function, especially in the setting of potentially cardiotoxic drugs and even after low to moderate doses of anthracyclines. A recent expert consensus paper strongly recommends GLS assessment for the detection of subclinical left ventricular dysfunction due to anthracycline therapy.

Although there is growing evidence that GLS can predict subsequent alterations in LVEF, few data exist on the optimal timing to perform echocardiography.

The investigators hypothesized that very early measurement of GLS in the time course of anthracycline therapy could predict subsequent left ventricular systolic dysfunction.

The aim of this study was, therefore, to determine whether assessment of GLS after 150 mg/m² of anthracyclines can predict AIC.

Description Study population: This is a single-centre, prospective cohort study. The patients are evaluated at four time points: visit 1 (V1), before the initiation of anthracycline therapy; visit 2 (V2), after reaching a cumulative dose of 150 mg/m²; visit 3 (V3), at the end of the treatment; and visit 4 (V4), 1 year after V1. Clinical examination at each visit and standard echocardiography are performed. The study is approved by our ethics committee (EudraCT number 2011-002721- 22). Two-dimensional echocardiography: Echocardiography examinations are performed using a Vivid E9 imaging device (GE Medical systems, Horten, Norway). The left ventricular end-diastolic and endsystolic volumes are measured from the apical two- and four-chamber views; LVEF are calculated using Simpson's rule. GLS is computed from high frame rate (>50 frames per second) apical views (four-, two-, and three-chamber). By tracing the endocardial borders on an end-systolic frame, myocardial speckles are automatically tracked on the subsequent frames. Adequate tracking is verified, and manually corrected if necessary. GLS is obtained as the average of regional strains. Percentage change in GLS and absolute reduction in GLS are calculated between baseline and V2. Other classic diastolic and systolic parameters are recorded according to current guidelines. Digital loops are stored for off-line analysis. For LVEF and GLS, digital loops are done in triplicate to assess inter- and intraobserver variability. LVEF and GLS are analysed by two readers. The readers are blinded to each other's measurements and to the patient visit number. Echocardiographic definition of AIC: According to a recent consensus paper, anthracycline cardiotoxicity is defined as a decrease in the LVEF of >10 percentage points, to a value <53%, at V4. This decrease has to be confirmed by a repeat echocardiography performed a few weeks after V4.
