Brief summary
The investigators hypothesize that the combination of Gemzar®, Abraxane® and Avastin will increase the progression-free survival (PFS) in patients with first line metastatic breast cancer and in patients who received neoadjuvant and/or adjuvant chemotherapy present with definable metastatic disease, 6 or more months after primary treatment.
Detailed description
This is a phase 2, single arm study. Participants will be treated with combination Gemzar, Abraxane and Avastin therapy until disease progression. Each treatment cycle is 28 days.
