Clinical Trials (PDQ®)
|Phase III||Treatment||Completed||18 to 70||NCI||NSABP-B-14|
I. Compare disease-free interval and survival of patients with negative axillary nodes following mastectomy for ER-positive breast cancer who are randomly assigned to adjuvant tamoxifen therapy vs. placebo. II. In conjunction with the results of NSABP-B-13, evaluate whether treatment failure and survival correlate with ER level in postmastectomy, node-negative patients who receive no further treatment. III. Evaluate the influence of both hormone receptor status and the interaction of radiotherapy and tamoxifen on the rate of local breast recurrence in patients who have undergone segmental mastectomy and axillary node dissection for their disease.
Histologically proven invasive carcinoma of the breast definitively removed by either: Total mastectomy with axillary node dissection Segmental mastectomy with axillary node dissection No more than 35 days between mastectomy and randomization, with radiotherapy planned on study No more than 4 weeks between diagnosis and mastectomy Histology established by excisional, incisional, or needle biopsy and aspiration cytology Tumor confined to the breast clinically, i.e., movable relative to the underlying muscle, chest wall, and skin Histologic proof of negative axillary nodes required Preoperatively palpable ipsilateral axillary nodes allowed if free of tumor Palpable contralateral axillary nodes or palpable supraclavicular or infraclavicular nodes must be biopsy-proven benign Hormone receptor status: ER-positive, i.e., at least 10 fmol/mg cytosol protein Quantitative PgR status required Receptor statuses must be known prior to randomization The following exclude: Ulceration Erythema Infiltration of the skin Peau d'orange or any degree of skin edema Satellite breast nodules Parasternal nodules Edema of the arm Infiltration of the skin Tethering, skin dimpling, and nipple inversion are not to be interpreted as skin infiltration and patients with these conditions are eligible Inflammatory carcinoma Histologies other than carcinoma Bilateral breast cancer Any mass in the contralateral breast must be biopsy- proven benign Metastatic disease Patients with bone pain with negative bone scan and/or x-rays are eligible Segmental mastectomy patients must additionally meet the following criteria: Tumor clinically no greater than 4 cm in greatest diameter Mammography preferred No diffuse tumor on xeroradiography or mammography considered surgically unsuited for lumpectomy No more than 1 malignant mass in the breast Other masses must be biopsy-proven benign No requirement for removal of nipple Breast is of a size to allow a cosmetically acceptable resection Breast sufficiently small to permit satisfactory irradiation No breast irradiation prior to randomization

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.
