Anastrozole and letrozole are nonsteroidal, reversible inhibitors of the aromatase enzyme and prevent the conversion of androgens to estrogens (Fig. 36-3). Exemestane differs in that its structure is steroidal in nature, and it irreversibly inhibits the aromatase enzyme. These agents are indicated for first- and second-line hormonal therapy in postmenopausal women with hormone receptor–positive breast cancer. Randomized clinical trials comparing 5years of each of the aromatase inhibitors with 5 years of tamoxifen have demonstrated superior survival rates in postmenopausal women receiving the aromatase inhibitor.
