Estrogen is the main hormone involved in the development and growth of hormone-dependent breast cancer. Endocrine adjuvant treatment in recent years focused primarily on the use of SERMs, mainly tamoxifen. Tamoxifen actions are complex. ⋯ Recently, the results of clinical trials comparing aromatase inhibitors to tamoxifen in post menopausal women with hormone-dependent breast cancer showed a benefit in favor of aromatase inhibitors in reducing the risk of recurrence. These trials were either comparative (for anastrozole) or sequential (for anastrozole, letrozole and exemestane). The issues of long term adverse effects (bone) and hormone treatment sequence remain to be addressed.
