Docetaxel plus epidoxorubicin as neoadjuvant treatment in patients with large operable or locally advanced carcinoma of the breast: a single-center, phase II study.

Background: The objective of this study was to test the activity and toxicity of epirubicin plus docetaxel as primary chemotherapy for women with large, operable (T2; > 3 cm) or locally advanced (Stage III) breast carcinoma, including patients with inflammatory breast carcinoma.

Methods: In this single-center, open-label, single-stage, Phase II trial, epirubicin (75 mg/m(2); intravenous bolus) followed by docetaxel (80 mg/m(2); 1-hour intravenous infusion) was administered on Day 1 of each cycle for four cycles.

Results: Nine of 30 patients (30%) had inflammatory breast carcinoma. Twenty-three patients (76.7%; 95% confidence interval, 57.7-90.1) had a clinical objective response that was complete in 6 patients (20%). Twenty-seven patients (90%) underwent surgery that was conservative in 5 patients (16.7%). Pathologic response evaluation revealed four complete responses (13.3%; 95% confidence interval, 3.8-30.7). Grade 4 neutropenia was recorded in 80.0% of patients, and febrile neutropenia was recorded in one-third of patients. Anemia and thrombocytopenia were never severe. Other side effects were diarrhea (26.6%), oral mucositis (43.3%), and emesis (26.6%).

Conclusions: Neoadjuvant chemotherapy with epirubicin plus docetaxel was a feasible treatment and was active in an unfavorable series of patients with locally advanced breast carcinoma, including patients with inflammatory breast carcinoma.
