Brief Summary: RATIONALE Estrogen can stimulate the growth of breast cancer cells Hormone therapy using tamoxifen may fight breast cancer by blocking the uptake of estrogen by the tumor cells

PURPOSE Randomized phase III trial to compare the effectiveness of at least 2 years of tamoxifen with that of 5 additional years of tamoxifen in treating women who have breast cancer that has been surgically removed
Detailed Description: OBJECTIVES

Compare the disease-free and overall survival of women with early breast cancer who are randomized to discontinue adjuvant tamoxifen vs those randomized to continue for at least 5 additional years

OUTLINE This is a randomized study Patients are stratified for analysis according to duration of tamoxifen given before randomization 2-3 years vs 4-5 years vs 6-7 years vs 8-9 years vs 10 years and over age less than 49 vs over 50 and important prognostic factors including tumor type and grade and nodal and estrogen receptor status Patients are randomized to 1 of 2 treatment arms

Arm I Patients discontinue tamoxifen after at least 2 years of prior treatment
Arm II Patients continue treatment with tamoxifen for at least 5 additional years in the absence of unacceptable toxicity or disease progression

Patients are followed annually
