Abstract
Tamoxifen and aromatase inhibitors are widely prescribed therapies for the treatment of breast cancer. Tamoxifen is a selective estrogen receptor modulator that treats hormone-sensitive breast cancers. Research has demonstrated that tamoxifen therapy improves survival and reduces the risk of developing recurrent invasive breast cancer by up to 40%.
Aromatase inhibitors are the drug of choice for the treatment of estrogen receptor– or progesterone receptor–positive breast cancer in postmenopausal women. Research on aromatase inhibitors has demonstrated improved survival in postmenopausal women, postmenopausal women with metastasis, and premenopausal women under the age of 35 with ovarian ablation.
The benefits of these agents have been clearly shown through various clinical trials, yet adherence may be challenging for some patients due to issues of drug interactions, proper education, and adverse effects. Education to prevent and treat adverse effects is of the utmost importance to promote adherence and improve the effectiveness of these medications. Advanced practitioners are in a position to prescribe these therapies, review medication interactions, educate patients, impact patients’ quality of life, improve patients’ sense of control, and increase patients’ partnerships with their oncology providers.
