OBJECTIVES:
* Determine the inhibitory effect of ICI 182780 on the development of metastasis, as measured by disease-free survival and overall survival, in women with operable stage I or II primary breast cancer.
* Determine toxicity of this regimen in these patients.
OUTLINE: This is a randomized, double-blind, placebo-controlled, multicenter study. Patients are stratified according to participating center and menopausal status (premenopausal vs postmenopausal).
Patients are randomized to receive either ICI 182780 IM or placebo IM over 2 minutes on day 1. Patients undergo surgery between days 8 and 29.
Patients are followed every 3 months for 2 years, every 6 months for 3 years, and then annually thereafter.
PROJECTED ACCRUAL: A total of 3,656 patients (1,828 per arm) will be accrued for this study within 2 years.
