Combination of docetaxel, epirubicin and vinorelbine administered every 2 weeks as first-line therapy in patients with metastatic breast cancer: a dose-finding study.

Aims: To assess efficacy and optimum combination dosage of intravenous docetaxel (T), epirubicin (E) and vinorelbine (N) administered every 2 weeks and without colony stimulating factor (CSF) support in patients with metastatic breast cancer (MBC).

Patients And Method: Patients (n = 5 1) with MBC were consecutively assigned to four different dose levels (DL) to receive (in mg/m2): Level I = T35 + E30 + N25; Level II = T30 + E30 + N25; Level III = T30 + E25 + N25; and Level IV = T25 + E25 + N25. Consecutive cycles were delayed if absolute neutrophil and/or platelet counts fell below 1.
