Breast Cancer
About this trial
This is an interventional treatment trial for Breast Cancer focused on measuring stage IA breast cancer, stage IB breast cancer, stage II breast cancer, stage IIIA breast cancer, HER2-positive breast cancer
Eligibility Criteria
DISEASE CHARACTERISTICS:
- Histologically confirmed invasive breast cancer
- No evidence of metastatic disease
- Overexpression of HER2 receptor defined as 3+ or 2+ HER2 positivity measured by fluorescent in situ hybridization (FISH) gene amplification
Indication for chemotherapy based on the following clinical and histopathological features:
Receiving or scheduled to receive neoadjuvant chemotherapy
- Time between diagnosis biopsy and start date of chemotherapy should be less than 1 month
Receiving or scheduled to receive adjuvant chemotherapy
- Completely resected disease, with negative surgical margins (apart from deep margin if full thickness resection)
- Marginally resected disease and/or positive sentinel nodes allowed provided patients undergo completion of surgery (breast and/or axillary clearance) after chemotherapy
- Hormone receptor status known
PATIENT CHARACTERISTICS:
- Menopausal status not specified
- ECOG performance status 0-1
- Adequate bone marrow, hepatic, and renal function
- LVEF normal by ECHO or MUGA
- Not pregnant or nursing
- Fertile patients must use effective contraception
- No clinically significant cardiac abnormalities
- No myocardial infarction within the past 6 months
- No uncontrolled or malignant hypertension
- No history of atrioventricular arrhythmia and/or congestive heart failure (even under medical control), or active second or third degree cardiac block
- No history of allergy to drugs containing polysorbate 20 and the excipient polysorbate 80 (TWEEN 80®) or history of allergy to mouse proteins
- No co-morbidity significantly adding to risks associated with cytotoxic chemotherapy (i.e., severe chronic obstructive pulmonary disease or poorly controlled diabetes)
No prior diagnosis of malignancy unless managed by surgical treatment only and disease-free for 10 years
- Prior basal cell carcinoma, cervical carcinoma in situ, or ductal carcinoma in situ of the breast allowed if treated by surgery only
- No concomitant medical or psychiatric problems that might preclude completion of treatment or follow-up
PRIOR CONCURRENT THERAPY:
- See Disease Characteristics
- No prior chemotherapy or radiotherapy
- Concurrent radiotherapy allowed

Patients receive trastuzumab IV over 30-90 minutes on day 1. Treatment repeats every 3 weeks for up to 12 months in the absence of disease progression or unacceptable toxicity. All patients also receive standard chemotherapy regimens as per local institutional protocols either concurrently with or sequentially to trastuzumab.
