Paclitaxel and bevacizumab in first-line treatment for HER2-negative metastatic breast cancer: single-center experience

The aim of our analysis was to report the outcome and safety of patients treated with bevacizumab and paclitaxel as first-line treatment for HER2-negative metastatic breast cancer. Between February 2009 and August 2011, 62 consecutive patients received paclitaxel 90 mg/m(2) on days 1, 8, and 15 and bevacizumab (BV) 10 mg/kg intravenously on days 1 and 15, every 28-day cycle. After 6 cycles of combined treatment, patients were given maintenance BV every 3 weeks (15 mg/kg) until progression disease or unacceptable toxicity. At time of analysis, median overall survival was 12.3 months (range 4.6-44.8 months), progression-free survival was 8.1 months (range 2.3-33.2 months), and time to treatment failure was 8.4 months (range 2.3-33.2 months). Our results confirmed the efficacy and the acceptable toxicity profile of bevacizumab plus paclitaxel as first-line regimen for metastatic breast cancer.
