    Abstract:
    OBJECTIVES: The aim of this work was to explore the value of serum vascular endothelial growth factor-A (VEGF-A) in patients with metastatic triple negative breast cancer (TNBC) treated with chemotherapy. The primary end point was overall survival (OS). Secondary end points were response rate (RR), progression-free survival (PFS) and VEGF-A level at baseline, mid-therapy and at the end of therapy. DESIGN AND METHODS: Female patients aged 18 years or above with histologically proven metastatic TNBC were included. Serum VEFG-A levels were measured at baseline, after the 3rd and 6th cycles of FAC chemotherapy regimen (Fluorourcil, Adriamycin, and Cyclophamide). RESULTS: The overall RR was 57%. The median PFS and OS were 7 and 11.2 months, respectively (95% CI: 4.3-9.7 and 3.8-18.5 months, respectively). Patients whose disease progressed despite therapy had a significantly higher baseline VEGF-A level than those who did not progress. VEGF-A level did not drop with continuation of therapy. Patients with high VEGF-A level had a significantly lower PFS but not OS than patients with low levels. CONCLUSION: The outcome of metastatic TNBC is poor with FAC chemotherapy regimen. Alternative chemotherapeutic regimens and novel therapeutic approaches including targeting of VEGF and/or its receptors are warranted.
