Kurze Zusammenfassung

RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Combining more than one drug and giving them after surgery may kill any remaining tumor cells following surgery. It is not yet known which combination chemotherapy regimen is more effective in treating breast cancer.

PURPOSE: Randomized phase III trial to compare the effectiveness of two different combination chemotherapy regimens in treating women who have primary breast cancer.

OBJECTIVES:

- Compare the time to progression of women with primary breast cancer treated with fluorouracil, epirubicin, and cyclophosphamide vs docetaxel, epirubicin, and cyclophosphamide.

- Compare the overall survival of patients treated with these regimens.

- Compare the toxicity of these regimens in these patients.

- Compare quality of life of patients treated with these regimens.

OUTLINE: This is a randomized, open-label, multicenter study. Patients are stratified according to metastatic axillary lymph node involvement (4-9 vs 10 or more), hormone receptor status (estrogen and/or progesterone) of the primary tumor (negative vs positive), and timing of adjuvant radiotherapy (intermittently after completion of 50% of chemotherapy vs after completion of all chemotherapy). Patients are randomized to 1 of 2 treatment arms.

- Arm I: Patients receive fluorouracil IV over 10-15 minutes and epirubicin IV over 15 minutes on days 1 and 8 and oral cyclophosphamide on days 1-14. Treatment repeats every 4 weeks for 6 courses in the absence of disease progression or unacceptable toxicity.

- Arm II: Patients receive epirubicin IV over 15 minutes and cyclophosphamide IV over 1 hour on days 1, 21, 42, and 63 and docetaxel IV over 1 hour on days 84, 105, 126, and 147 in the absence of disease progression or unacceptable toxicity.

Within 21 days after the completion of chemotherapy, patients undergo adjuvant radiotherapy 5 days a week for 5.5 weeks. Alternatively, patients may undergo radiotherapy intermittently after completion of 50% of chemotherapy.

Upon completion of chemotherapy, patients with positive hormone receptor status (estrogen and/or progesterone) receive oral tamoxifen daily for 5 years. Additionally, patients with positive hormone receptor status who are under age 40 receive goserelin subcutaneously every 4 weeks for 2 years.

Quality of life is assessed at baseline, prior to each course of chemotherapy, 4 weeks after completion of chemotherapy, 6 weeks after completion of radiotherapy, and then at 6 months after completion of chemotherapy.

Patients are followed every 3 months for 3 years, every 6 months for 3 years, and then annually thereafter.

PROJECTED ACCRUAL: A total of 446 patients (223 per treatment arm) will be accrued for this study within 3 years.
