This is a prospective, open-label, randomized, phase III trial. Patients will be stratified after breast surgery, as per investigational site; menopausal status; node negative diagnosis, as per sentinel-node technique versus lymphadenectomy; hormone receptor status (positive versus negative). Patients will be randomized to:
- FAC x 6 (cycles): 5-fluorouracil 500 mg/m2 + doxorubicin 50 mg/m2 + cyclophosphamide 500 mg/m2 day 1, every 3 weeks, for 6 cycles.
- FAC x 4 (cycles) → Taxol® x 8 (cycles): 5-fluorouracil 500 mg/m2 + doxorubicin 50 mg/m2 + cyclophosphamide 500 mg/m2 day 1, every 3 weeks, for 4 cycles, followed by 8 administrations of weekly paclitaxel 100 mg/m2
Premenopausal women with hormone receptor positive tumors must receive tamoxifen 20 mg daily for 5 years, after the end of chemotherapy.
Postmenopausal women with hormone receptor positive tumors are allowed to receive aromatase inhibitors as initial adjuvant hormone therapy or after tamoxifen.
All patients with breast conservative surgery must receive radiotherapy.
Estimated 5-year disease-free survival in the control arm (FAC x 6) is expected to be 80%. It is expected that disease-free survival will increase by 5% in the experimental arm (FAC-paclitaxel). 906 patients per arm must be recruited, to detect this difference with an alpha error of 0.05 and 80% power. Assuming a 6% post-randomization drop-out rate, 960 patients per arm are needed, 1920 in total.

FAC X 6
FAC x 6: 5-fluorouracil 500 mg/m2 i.v. + doxorubicin 50 mg/m2 i.v. + cyclophosphamide 500 mg/m2 i.v. every 3 weeks, for 6 cycles.
FAC X 4 + 8 Taxol
FAC x 4 -> Taxol x 8:
5-fluorouracil 500 mg/m2 i.v. + doxorubicin 50 mg/m2 i.v. + cyclophosphamide 500 mg/m2 i.v. every 3 weeks, for 4 cycles followed by weekly Taxol 100 mg/ m2 for 8 cycles (days 1, 8, 15, 22, 29, 36, 43 y 50).
