Summary
Brief summary (as posted)
RATIONALE: Estrogen can stimulate the growth of breast cancer cells. Hormone therapy using tamoxifen may fight breast cancer by blocking the uptake of estrogen. Chemotherapy uses different ways to stop tumor cells from dividing so they stop growing or die. Combining chemotherapy with hormone therapy may kill more tumor cells. It is not yet known which treatment regimen is most effective for breast cancer. PURPOSE: Randomized phase III trial to compare the effectiveness of tamoxifen with that of ovarian ablation, and/or combination chemotherapy in treating premenopausal women with stage I, stage II, or stage IIIA breast cancer.
