Abstract
- Locally advanced breast cancer (LABC) is a good setting in which to monitor response to neoadjuvant chemotherapy, to downsize the tumor (which facilitates breast-conserving surgery), and to test newer agents in untreated patients. Eribulin (E) has shown activity in patients who have undergone previous taxane, anthracycline, and capecitabine treatment. We aimed to evaluate the neoadjuvant use of E followed by doxorubicin and cyclophosphamide (AC) in patients with HER2-negative LABC, using as a control a randomized group of women who received weekly paclitaxel (WP). Fifty women with LABC were accrued January-August 2013. Patients were randomized (1:2) to receive either WP (N = 19) for 12 treatments or E (N = 31) every 3 weeks for 4 cycles followed by AC every 3 weeks for 4 cycles before surgery. 17/19 patients who took WP and 25/30 who took E completed all cycles. Patients were evaluated by clinical examination and breast MRI at baseline and after completion of E or WP. Surgical pCR in breast and lymph nodes was determined by a local pathologist following chemotherapy. Forty-nine patients received ≥1 dose of neoadjuvant chemotherapy and are included in this analysis. Forty-eight underwent surgery; one had disease that was inoperable (on E) and is included as no-pCR patient. 17/19 of these patients who took WP completed 12 doses; 28/30 on E completed 4 cycles. Six discontinued treatment on WP, E, or AC. Both treatments were well tolerated. pCR on WP = 5/19(26 %) and on E = 5/30(17 %). Both regimens were equally well tolerated with no unexpected toxicities. pCR did not suggest higher activity with E than with other standard regimens in these LABC patients.
