RATIONALE: Estrogen can stimulate the growth of breast cancer cells. Hormone therapy using ICI 182780 before surgery may block the uptake of estrogen by the tumor cells and prevent metastases. It is not yet known if ICI 182780 is effective in preventing breast cancer metastases.

PURPOSE: Randomized phase III trial to study the effectiveness of ICI 182780 given before surgery in treating women who have stage I or stage II primary breast cancer.

Condition Intervention Phase
Breast Cancer
Drug: fulvestrant
Procedure: conventional surgery
Phase 3

Study Type: Interventional
Study Design: Primary Purpose: Treatment
Official Title: A Double-Blind Phase III Clinical Trial to Compare the Effects of a Pre-Operatively Administered Single Dose of "Faslodex" (Long-Acting ICI 182.780) With Placebo on Tumor Recurrence in Pre- and Postmenopausal Women Treated for Operable First Primary Breast Cancer

Further study details as provided by European Organisation for Research and Treatment of Cancer - EORTC:

Study Start Date: November 2000
Primary Completion Date: October 2001 (Final data collection date for primary outcome measure)
Detailed Description:


  • 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.
