Brief summary
This project is investigating the optimal use of docetaxel and doxorubicin in the treatment of women with breast cancer and involved lymph nodes (N+). The efficacy of adjuvant chemotherapy in early breast cancer is well established by the international overview conducted by the Early Breast Cancer Trialist's Collaborative Group (EBCTCG). They have demonstrated the efficacy of adjuvant chemotherapy on reducing mortality and recurrence rates, but current regimens are far from optimal. Docetaxel (Taxotere), a new agent, has effectiveness and manageable side effects in the treatment of advanced breast cancer patients, and can plausibly improve outcomes for patients with early N+ breast cancer by optimal integration into current adjuvant chemotherapy regimens. This clinical trial is designed to compare whether it is advantageous to use docetaxel and/or doxorubicin in combination or sequentially with other currently available chemotherapy drugs
Interventions
Arm A1:doxorubicin 75 mg/m² i.v. once every 21 days for 4 cycles, followed by CMF (C = Cyclophosphamide - 100 mg/m² orally for days 1-14, M = Methotrexate - 40 mg/m² i.v. on days 1 and 8, FU = Flourouracil - 600 mg/m² i.v. days 1 and 8, every 28 days) for 3 cycles. (total treatment duration is 24 weeks) Arm A2:doxorubicin 60 mg/m² i.v. and cyclophosphamide 600 mg/m² i.v., once every 21 days for 4 cycles, followed by CMF (C = Cyclophosphamide - 100 mg/m² orally for days 1-14, M = Methotrexate - 40 mg/m² i.v. on days 1 and 8, FU = Flourouracil - 600 mg/m² i.v. days 1 and 8, every 28 days) for 3 cycles. (total treatment duration is 24 weeks) Arm B: doxorubicin 75 mg/m² i.v. day once every 21 days for 3 cycles, followed by Docetaxel 100 mg/m² i.v., once every 21 days for 3 cycles, followed by CMF (C = Cyclophosphamide - 100 mg/m² orally for days 1-14, M = Methotrexate - 40 mg/m² i.v. on days 1 and 8, FU = Flourouracil - 600 mg/m² i.v. days 1 and 8, every 28 days) for 3 cycles. (total treatment duration is 30 weeks) Arm C: doxorubicin 50 mg/m² i.v. and docetaxel 75 mg/m² i.v. once every 21 days for 4 cycles, followed by CMF (C = Cyclophosphamide - 100 mg/m² orally for days 1-14, M = Methotrexate - 40 mg/m² i.v. on days 1 and 8, FU = Flourouracil - 600 mg/m² i.v. days 1 and 8, every 28 days) for 3 cycles. (total treatment duration is 24 weeks)

Eligibility
Inclusion criteria
