Biweekly docetaxel and gemcitabine as neoadjuvant chemotherapy followed by adjuvant doxorubicin and cyclophosphamide therapy in stage II and III breast cancer patients: results of a phase II study.

INTRODUCTION: The purpose of this phase II study was to evaluate the efficacy and safety of neoadjuvant docetaxel/gemcitabine treatment in a biweekly regimen.
MATERIALS AND METHODS: Patients with stage II/III breast cancer were treated with docetaxel (65 mg/m(2)) followed by gemcitabine (2500 mg/m(2)) every 2 weeks for 6 cycles. Patients with a clinical response or stable disease underwent mastectomy or breast-conserving surgery plus axillary dissection. After surgery, patients received 4 cycles of standard doxorubicin 60 mg/m(2) and cyclophosphamide 600 mg/m(2) every 21 days.
RESULTS: Thirty-five patients were included in the trial. The overall response rate was 71.4% (95% CI: 53.7-85.4), with 8 complete and 17 partial responses. Breast conservation was possible in 59% of the patients. Toxicity was manageable.
CONCLUSIONS: We consider biweekly docetaxel and gemcitabine could be an active and tolerable regimen option in the neoadjuvant setting sequentially with standard adjuvant doxorubicin-cyclophosphamide in patients with stage II or III breast cancer.
