Résumé

The efficacy of the combination bevacizumab-chemotherapy in the first-line treatment of metastatic breast cancer (mBC) was demonstrated in several randomized clinical trials. However, limited safety data is available in daily medical practice. ATHENA is an international phase-IIIb study conducted in 2,251 patients with locally advanced or mBC, treated in first-line with bevacizumab combined with taxanes-based chemotherapy. The primary objective is safety assessment. In France, 365 patients were included. Their median age was 56 years (24-93 years) and ECOG performance status was 0 or 1 in 93.9% of patients. Bevacizumab was essentially combined with a taxanes monotherapy: docetaxel (37.3%) or paclitaxel (28.8%) or taxanes-based combination therapy (9.4%). The most frequent grade superior or equal to 3 adverse event (AE) was neutropenia (34.5%). Grade superior or equal to 3 AEs of special interest related to bevacizumab were arterial and venous thromboembolism (5.1%), high blood pressure (4.2%), proteinuria (2.3%) and hemorrhage (2%). Median time to progression was 9.5 months (95% CI: 8.8-10.4). The safety profile and the efficacy of the combination bevacizumab-taxanes in a population more representative of daily oncology practice in France are comparable to those reported in clinical trials in mBC.
