Sumario:Background. Adding taxanes to anthracycline-based adjuvant chemotherapy has shown significant improvement in node-positive breast cancer patients but the optimal dose schedule has still remained undetermined. Objectives. The feasibility of dose-dense epirubicin in combination with cyclophosphamide (EC) followed by weekly paclitaxel as adjuvant chemotherapy in node-positive breast cancer patients was investigated. Methods. All patients were treated with epirubicin (100 mg/m(2)) and cyclophosphamide (600 mg/m(2)) every two weeks for four cycles with daily Pegfilgrastim (G-CSF) that was administered 3–10 days after each cycle of epirubicin and cyclophosphamide infusion which followed by (80 mg/m(2)) paclitaxel for twelve consecutive weeks. Results. Sixty consecutive patients were analyzed, of whom 57 patients (95%) completed the regimen and no case of toxicity-related death was observed. Grade 3/4 hematologic toxicity was uncommon and the most common grade 3/4 nonhematological adverse event was neuropathy disorders. Conclusions. Dose-dense epirubicin and cyclophosphamide followed by weekly paclitaxel with G-CSF support is a well-tolerated and feasible regimen in node-positive breast cancer patients without serious complications.
