| Phase | Type | Status | Age | Sponsor | Protocol IDs |
|---|---|---|---|---|---|
| Phase III | Treatment | Closed | 18 to 78 | NCI | NSABP-B-28 |
Objectives
I. Compare disease-free survival and overall survival of patients with resected node-positive breast cancer treated with 4 courses of paclitaxel following 4 courses of doxorubicin/cyclophosphamide (AC) vs. 4 courses of AC alone.
Entry Criteria
Disease Characteristics:
Completely resected breast cancer
Clinically confined to 1 breast and ipsilateral nodes (T1-3, N0-1, M0)
Bone scan and/or x-rays negative for metastases in presence of bone pain
X-ray, magnetic resonance imaging, or biopsy confirmation required for
suspicious lesions
Total mastectomy/lumpectomy and axillary node dissection required
Histologic confirmation of invasive adenocarcinoma
At least 1 involved axillary lymph node
Additional criteria for lumpectomy:
Primary tumor no greater than 5 cm on physical exam
No invasive tumor or ductal carcinoma in situ in resection margins
Re-excision permitted to obtain clear margins
Total mastectomy required if clear margins unobtainable
No diffuse tumors on mammogram unless surgically amenable to lumpectomy
No ipsilateral mass following lumpectomy unless histologically benign
No breast irradiation prior to randomization
None of the following:
Contralateral breast cancer
Biopsy required for:
Suspicious mass in breast
Suspicious palpable axillary node
Palpable supraclavicular or infraclavicular node
Ulceration
Erythema
Infiltration of skin or underlying chest wall
Tethering or dimpling of skin, or nipple inversion only, allowed
Peau d'orange or skin edema of any magnitude
Hormone receptor status:
Estrogen and progesterone receptor status required prior to randomization
Randomization within 63 days of initial cytologic or histologic diagnosis
Prior/Concurrent Therapy:
No prior therapy for breast cancer other than surgery Segmental resection of ipsilateral or contralateral lobular carcinoma in situ allowed No prior anthracycline for any malignancy No concurrent sex hormone therapy (e.g., birth control pills, ovarian hormone replacement therapy)
Patient Characteristics:
Age:
18 to 78
Sex:
Not specified
Menopausal status:
Not specified
Performance status:
Not specified
Life expectancy:
At least 10 years
Hematopoietic:
(at time of randomization)
WBC at least 4,000/mm3
Platelet count at least 100,000/mm3
Hepatic:
(at time of randomization)
Bilirubin normal
AST or ALT normal
Renal:
(at time of randomization)
Creatinine normal
Cardiovascular:
No contraindication to doxorubicin or paclitaxel therapy, including:
Myocardial infarction
Angina pectoris requiring medication
History of documented congestive heart failure
Arrhythmia requiring medication
Severe conduction abnormality
Valvular disease with documented cardiac function compromise
Cardiomegaly on chest x-ray or ventricular hypertrophy on EKG unless left
ventricular ejection fraction at least 45% on MUGA or echocardiogram
Poorly controlled hypertension, i.e., diastolic above 100 mm Hg
Concurrent medication that alters cardiac conduction (e.g., digitalis, beta-
blockers, calcium channel blockers) allowed for hypertension or noncardiac
condition
Other:
No nonmalignant systemic disease that precludes treatment or follow-up
No psychiatric or addictive disorder that precludes informed consent
No second malignancy within 10 years except:
Effectively treated nonmelanomatous skin cancer
Surgically treated carcinoma in situ of the cervix
No pregnant women
Chest x-ray within 3 months prior to randomization
Bilateral mammogram, bone scan, EKG, and gynecologic exam within 1 year prior
to randomization
Expected Enrollment
This study will accrue 3050 patients over 21 months.
Outline
This is a randomized study. Patients are stratified on the basis of number of positive nodes, tamoxifen assignment (based on age and hormone-receptor status), type of surgery, and participating institution. Randomization must occur within 63 days of initial diagnosis, and treatment begins no sooner than 2 weeks after the last surgery. Patients in the first group receive doxorubicin and cyclophosphamide (AC) every 21 days for 4 courses. Patients in the second group receive paclitaxel every 21 days for 4 courses following completion of AC as in the first group. All patients over 50 years of age or with hormone-receptor-positive tumors receive oral daily tamoxifen for 5 years, beginning concurrently with chemotherapy. Patients who underwent lumpectomy receive radiotherapy upon completion of their chemotherapy. Granulocyte colony-stimulating factor is prohibited except to treat life-threatening infection, febrile neutropenia, or prolonged granulocytopenia. Hormonal therapy other than tamoxifen is prohibited on study. Patients are followed every 6 months for 2.5 years, then yearly.Published Results

Note: The purpose of most clinical trials listed in this database is to test new cancer treatments, or new methods of diagnosing, screening, or preventing cancer. Because all potentially harmful side effects are not known before a trial is conducted, dose and schedule modifications may be required for participants if they develop side effects from the treatment or test. The therapy or test described in this clinical trial is intended for use by clinical oncologists in carefully structured settings, and may not prove to be more effective than standard treatment. A responsible investigator associated with this clinical trial should be consulted before using this protocol.
