Abstract
Tamoxifen (Nolvadex) (Fig. 1), a nonsteroidal antiestrogen, is the endocrine treatment of choice for all stages of breast cancer. The drug has ten million women-years of clinical experience and is described by the World Health Organization as an essential treatment for breast cancer. The clinical pharmacology of tamoxifen has been studied in great detail because it is currently being tested as a preventive for breast cancer in high-risk women (Jordan 1993). This strategy is based on three important facts. Firstly, tamoxifen prevents rat mammary carcinogenesis (Jordan 1974, 1976). Secondly, tamoxifen reduces the incidence of contralateral breast cancer (Cuzik and Baum 1985) and, thirdly, when the preliminary studies were started in 1986 (Powles et al. 1989), tamoxifen was believed to have a low incidence of side effects (Furr and Jordan 1984).
This article is dedicated to Professor E. V. Jensen on the occasion of the 40th anniversary of the first report of the specific binding of estrogen in estrogen target tissues. These studies were supported by the NIH grant CA-56143. The author is grateful for the continuing support of the Lynn Sage Breast Cancer Foundation of Northwestern Memorial Hospital.
