PURPOSE: Randomized phase III trial to compare the effectiveness of therapy with or without axillary lymph node dissection following quadrantectomy in treating older women with stage I breast cancer that is estrogen receptor positive.
- Compare the efficacy of quadrantectomy with or without axillary lymph node dissection, followed by tamoxifen in terms of local and distant relapse rates and overall survival of patients with stage I, invasive breast cancer.
- Determine the relationship between biological variables, such as hormone receptor status, cell proliferation, and DNA ploidy, and the clinical outcome of the disease in these patients.
OUTLINE: This is a randomized, multicenter study. Patients are stratified by center. Patients are randomized to 1 of 2 treatment arms.
- Arm I: Patients undergo quadrantectomy with dissection of level I and II axillary lymph nodes.
- Arm II: Patients undergo quadrantectomy without axillary lymph node dissection. Patients on both arms receive tamoxifen daily for 5 years.
Patients are followed every 4 months for 2 years, every 6 months for 2 years, and then annually thereafter.
PROJECTED ACCRUAL: A total of 642 patients will be accrued for this study within 3 years.
Allocation: Randomized, Control: Active Control, Primary Purpose: Treatment

Tamoxifen is frequently prescribed to prevent breast cancer recurrence. Tamoxifen is a prodrug and requires bioactivation by CYP2D6. Tamoxifen use is often limited by adverse effects including severe ...
Abnormal accumulation of lymph in the arm, shoulder and breast area associated with surgical or radiation breast cancer treatments (e.g., MASTECTOMY).
Metastatic breast cancer characterized by EDEMA and ERYTHEMA of the affected breast due to LYMPHATIC METASTASIS and eventual obstruction of LYMPHATIC VESSELS by the cancer cells.
A infiltrating (invasive) breast cancer, relatively uncommon, accounting for only 5%-10% of breast tumors in most series. It is often an area of ill-defined thickening in the breast, in contrast to the dominant lump characteristic of ductal carcinoma. It is typically composed of small cells in a linear arrangement with a tendency to grow around ducts and lobules. There is likelihood of axillary nodal involvement with metastasis to meningeal and serosal surfaces. (DeVita Jr et al., Cancer: Principles & Practice of Oncology, 3d ed, p1205)
A deoxycytidine derivative and fluorouracil PRODRUG that is used as an ANTINEOPLASTIC ANTIMETABOLITE in the treatment of COLON CANCER; BREAST CANCER and GASTRIC CANCER.
Carbohydrate antigen elevated in patients with tumors of the breast, ovary, lung, and prostate as well as other disorders. The mucin is expressed normally by most glandular epithelia but shows particularly increased expression in the breast at lactation and in malignancy. It is thus an established serum marker for breast cancer.
