History of Changes

Purpose

The purpose of this study is to determine whether cessation of hormone replacement therapy for one or two months before a screening mammogram will improve its performance by decreasing breast density.

Estimated Enrollment:	1500
Study Start Date:	November 2004
Estimated Study Completion Date:	November 2006

Detailed Description:

This randomized, controlled trial is designed to test whether short-term (1-2 months) HRT cessation will sufficiently lower breast density to decrease the proportion of women who receive a recommendation for additional evaluation following a screening mammogram, and to examine whether there is a trend by duration of cessation. The study is being conducted at Group Health Cooperative, a managed health care organization in western Washington State with an organized breast cancer screening program. We are recruiting 1,500 women and will randomize women to one of three HRT arms: 1) cessation two months before the screening mammogram; 2) cessation one month before; and 3) continued HRT use. We are using a computer-assisted method to measure mammographic breast density continuously. Mammography recall rates are being determined from an expert radiologist review of the mammograms, blinded to HRT status.
