Brief Summary

RATIONALE: Drugs used in chemotherapy work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Monoclonal antibodies, such as trastuzumab, can block tumor growth in different ways. Some block the ability of tumor cells to grow and spread. Others find tumor cells and help kill them or carry tumor-killing substances to them. It is not yet known which regimen of combination chemotherapy given together with trastuzumab is most effective in treating breast cancer.

PURPOSE: This randomized phase III trial is comparing two different regimens of combination chemotherapy given together with trastuzumab to see how well they work in treating women with HER2-positive stage I, stage II, or stage III breast cancer.

Detailed Description

OBJECTIVES:

Primary

• To evaluate if 3 months of trastuzumab (Herceptin®) administered according to the Finnish protocol (9-weekly administrations) is not inferior to 12 months (18 three-weekly administrations) in a standard chemotherapy protocol, in terms of disease-free survival, in patients with HER2-positive early breast cancer.
• To determine overall survival of patients treated with these regimens.

Secondary

• To determine the failure rate at 2 years, calculated as cumulative incidence of relapse, contralateral breast cancer (excluding in situ carcinoma), death for all causes, and treatment withdrawal due to toxicity of therapy.
• To determine the incidence of cardiac events (defined as decrease of ejection fraction (EF) over 15% from basal values, or decrease over 10% with EF absolute value below 50%, or symptomatic cardiac failure, or other cardiac side effects grade 2 or more according to NCI CTCAE v.3.

OUTLINE: This is a multicenter study. Patients are stratified according to nodal status (positive vs negative), hormone-receptor status (estrogen receptor-positive vs progesterone receptor-positive disease), and Regional Coordinating Center. Patients are randomized to 1 of 2 treatment arms.

• Arm I (standard long-term adjuvant treatment-12 months): Patients receive chemotherapy comprising either doxorubicin hydrochloride IV and cyclophosphamide IV or epirubicin hydrochloride IV and cyclophosphamide IV on day 1. Treatment repeats every 21 days for up to 4 courses in the absence of disease progression or unacceptable toxicity.

Patients then receive paclitaxel IV over 3 hours or docetaxel* IV over 1 hour and concurrent trastuzumab (Herceptin®) IV over 90 minutes. Treatment repeats every 21 days for up to 4 courses.

NOTE: *Patients < 65 years old receive a higher dose of docetaxel and patients ≥ 65 years old receive a lower dose of docetaxel.

After completion of chemotherapy and concurrent trastuzumab, patients receive trastuzumab IV over 30-60 minutes as monotherapy every 21 days for up to 14 courses in the absence of disease progression or unacceptable toxicity.

• Arm II (experimental short-term adjuvant treatment-3 months): Patients receive docetaxel** IV on day 1. Treatment repeats every 21 days for up to 3 courses. Patients also receive trastuzumab IV over 30-60 minutes on day 1. Treatment repeats weekly for up to 9 weeks (9 doses).

Within 21 days after completion of docetaxel therapy, patients receive fluorouracil IV, epirubicin hydrochloride IV, and cyclophosphamide IV on day 1. Treatment repeats every 21 days for up to 3 courses.

NOTE: **Patients < 65 years old receive a higher dose of docetaxel and patients ≥ 65 years old receive a lower dose of docetaxel.

In both arms, patients treated with conservative surgery or those with more than 4 positive axillary nodes undergo radiotherapy within 8 weeks after completion of chemotherapy. Patients enrolled in arm I undergo radiotherapy concurrently with trastuzumab.

Patients with hormone receptor-positive tumor (i.e., estrogen receptor and/or progesterone receptor-positive tumor) also receive hormonal treatment after completion of chemotherapy. Patients enrolled in arm I receive hormonal therapy concurrently with trastuzumab.

Premenopausal patients receive monthly luteinizing-hormone releasing-hormone agonist for 2 years plus daily tamoxifen citrate for 5 years. Post-menopausal patients receive an aromatase inhibitor daily for 5 years.

After completion of study therapy, patients are followed for up to 3 years.
