Abstract

BACKGROUND:

Bevacizumab with chemotherapy improves outcomes in patients with metastatic breast cancer (MBC). The purpose of this trial was to determine the activity and safety profile of neoadjuvant bevacizumab with chemotherapy in women with locally advanced breast cancer (LABC).

METHODS:

Between November 2006 and August 2007, 45 women with HER2(-) LABC began preoperative standard AC (doxorubicin [Adriamycin], cyclophosphamide) × 4 cycles followed by docetaxel 75 mg/m(2) intravenously (I.V.) on day 1 and capecitabine 825 mg/m(2) twice daily on days 1-14 (TX, docetaxel [Taxotere] and capecitabine [Xeloda]) every 21 days for 4 cycles. Bevacizumab 15 mg/kg I.V. was given concurrently with chemotherapy every 21 days for a total of 6 preoperative doses. Postoperatively bevacizumab was resumed for a total of 10 doses. The primary endpoint was pathologic complete response (pCR) in the breast.

RESULTS:

Thirty patients (66.7%) had stage IIIA disease, 12 (26.7%) patients had stage IIIB, and 3 patients (6.7%) had stage IIIC. Of these, 10 (22%) had inflammatory breast cancer (IBC), and 27 (60%) had estrogen receptor (ER)(+) disease. A pCR in the breast with negative axillary nodes was documented in 4 (9%) of 45 patients. Toxicities that were seen with AC and bevacizumab included fatigue (grade 2/3; 31% and 9%, respectively), mucositis (grade 2/3; 29% and 2%, respectively), and headache (grade 2/3; 16% and 7%, respectively). Toxicities seen with TX and bevacizumab included mucositis (grade 2/3; 48% and 25%, respectively), fatigue (grade 2/3; 43% and 18%, respectively), and hand-foot syndrome (grade 2/3; 34% and 23%, respectively).

CONCLUSIONS:

This regimen demonstrated only modest activity with substantial toxicity and does not appear to warrant further evaluation.
